Description

  The present invention relates to a cap seal attached to various containers such as a beverage container.

Conventionally, a cap seal has been used to protect the cap portion of a container in which beverages, seasonings and the like are placed, and to ensure that the cap portion is not opened.
A cap perforation is usually formed on the cap seal. A person who purchases a container with a cap seal in which the cap seal is attached to the container cuts and opens the container with a horizontal perforation for opening.
In this respect, mischief such as breaking the cap seal may be performed. For example, even though there is no intention to purchase, there is a case where the cap seal is turned and broken at the opening perforation, and then returned to the original state so that the cap seal appears to be unopened. Hereinafter, breaking the cap seal for such a mischievous purpose is referred to as “illegal opening”.

  Patent Document 1 includes a container with a cap and cap seals each formed with an auxiliary perforation extending substantially parallel to the opening horizontal perforation, and the auxiliary perforation is formed above the opening horizontal perforation. In the cap seal, the horizontal perforation for opening is located below the upper end portion of the trunk portion or the upper end portion of the trunk portion, and the auxiliary perforation is below the portion 3 mm upward from the lower end portion of the cap. A cap-sealed container is disclosed that is heat-shrink mounted. For such a container with a cap seal, when the cap seal is rotated, it is cut at the auxiliary perforation, and an indefinite cut piece is generated. By visually recognizing such a cut piece, it can be visually determined that it has been tampered with.

  However, even if a cut piece is generated by the unauthorized opening, a customer or a sales clerk can make a mischief by removing the cut piece or returning the cut piece to its original state. There may be a situation where it is not possible to determine whether the tampering has been opened at a glance. Furthermore, in the case of over-the-counter sales in which a large number of customers purchase a large number of products, it is possible to overlook the fact that the tampering has been opened when a cashier operation (settlement of products) is required for the customer as soon as possible. In other words, it may be difficult to discover a tampered fact with the human eye alone.

[First Embodiment]
<Cap seal>
The cap seal A of the present invention includes a cylindrical body 1 that can be thermally contracted in the circumferential direction, a reading region 2 provided in the cylindrical body 1, and a breakage auxiliary line 3 formed in the cylindrical body 1. The breaking auxiliary line 3 is arranged so that the virtual extension line of the breaking auxiliary line 3 intersects the edge of the reading region 2.
The cylindrical body 1 is formed by forming a heat-shrinkable film into a cylindrical shape. The cap seal A before being heat-shrink mounted on the container can be opened in a cylindrical shape as shown in FIGS. In the present invention, it should be noted that “cap seal A” means a state before being attached to the container. In the following, the cap seal before heat shrinking is denoted by A and the cap seal after heat shrink fitting on the container is denoted by B.
The cap seal A is opened in a cylindrical shape when attached to a container, but is folded into a flat shape as shown in FIGS. 3 to 5 during normal transportation and storage. In the illustrated example, the cap seal A is folded in a flat shape with a central portion in the width direction (corresponding to the circumferential direction of the cylindrical body 1) of a mechanical reading medium 21 described later as a fold.
In a realistic manufacturing process, the cap seal A is a continuous body in which a plurality of cap seals A are continuously connected, and is provided in the form of a continuous body that is folded into a flat shape. The cap seal A is obtained.

The heat-shrinkable film is a film that shrinks in the heat shrink direction when heated to a heat shrink temperature. Examples of the heat shrink temperature include 60 ° C to 120 ° C.
Examples of the heat-shrinkable film include heat-shrinkable synthetic resin films, nonwoven fabrics, foamed resin films, and laminated films thereof. The laminated film may be a laminate of a layer having no heat shrinkability and a layer having heat shrinkability, provided that the whole laminate has heat shrinkability. Preferably, a synthetic resin film or a synthetic resin laminated film is used as the heat-shrinkable film.
The material of the synthetic resin film or the synthetic resin laminated film is not particularly limited, and polyester resins such as polyethylene terephthalate and polylactic acid; olefin resins such as polypropylene and cyclic olefin; polystyrene such as polystyrene and styrene-butadiene copolymer. One type selected from thermoplastic resins such as polyamide resins; vinyl chloride resins; or a mixture of two or more types. The heat-shrinkable synthetic resin film may be composed of a single resin layer, or may be composed of a plurality of different or different types of resin layers. Since it is relatively soft and easy to tear in the circumferential direction, it is preferable to use a film including a polystyrene resin layer. Furthermore, a polystyrene resin film or a laminated film in which a polystyrene resin layer and a polyester resin layer are laminated is used. More preferably, it is used.
Although the thickness of the heat-shrinkable film is not particularly limited, for example, a film having a thickness of about 20 μm to 100 μm, further about 20 μm to 80 μm can be used.

As the heat-shrinkable film, a film that mainly heat-shrinks in at least the first direction may be used, and a film that slightly heat-shrinks or heat-extends in the second direction may be used. The first direction means one direction in the plane of the film, and the second direction is a direction orthogonal to the first direction in the plane. As such a heat-shrinkable film, a uniaxially stretched or biaxially stretched film mainly stretched in the first direction can be used. Such a stretched film is oriented at least in the first direction, and has a property of tearing easily in the first direction (tearability).
The heat shrinkage rate in the first direction (heat shrink direction) of the heat shrinkable film is not particularly limited, but is preferably 20% or more, more preferably 30% or more, and further preferably 40% or more. is there. In addition, although the heat shrinkage rate in the said 1st direction is so preferable that it is large, since there exists a limit naturally, the heat shrinkage rate in the said 1st direction is theoretically less than 100%. When the heat-shrinkable film is a film that changes heat in the second direction, the heat shrinkage rate in the second direction is, for example, −3 to 15%, preferably 0 to 12%. The minus of the thermal contraction rate means thermal elongation.
However, the heat shrinkage ratio is a ratio of the length of the film before heating (original length) and the length of the film after immersion in warm water at 85 ° C. for 10 seconds (length after immersion). Substituting into the following formula.
Thermal contraction rate (%) = [{(original length in first direction or second direction) − (length after immersion in first direction or second direction)} / (first direction or second direction Original length)] × 100.

The film is rolled into a cylindrical shape so that the first direction (heat shrink direction) of the heat-shrinkable film is the circumferential direction, and the first side end 11 is overlapped with the second side end 12 and bonded. The cylindrical body 1 is configured by forming the seal portion 13. The seal portion 13 extends in a strip shape in the axial direction of the cylindrical body 1.
The bonding method of the first side end portion 11 and the second side end portion 12 is not particularly limited, and examples thereof include welding using a solvent and bonding using an adhesive.
The circumferential length of the cylindrical body 1 is, for example, more than the maximum circumference x 1 times of the portion to which the container is mounted x 1 x 1.5 times, preferably x 1.01 times to x 1.3 times the same. More preferably, it is the same × 1.02 times to the same × 1.15 times.

A mechanical reading medium 21 is provided in a partial area in the plane of the cylindrical body 1.
The mechanical reading medium 21 contains predetermined information, which is read by an optical or electrical reader. By providing the mechanical reading medium 21 in the cylindrical body 1, information that can be read mechanically is provided in the reading area 2.
The optically read information is converted into a one-dimensional or two-dimensional code according to a certain rule, and is replaced with an optically readable display (mechanical reading medium). Examples of such optical reading display include a bar code as shown in the illustrated example, and a matrix type two-dimensional code such as a QR code (registered trademark), a stack type two-dimensional code, etc., although not shown. By providing a display such as a bar code in a partial area of the cylindrical body 1, a mechanical reading medium 21 is provided in that area. Such a display is generally formed by a printing method. The display is printed on the inner surface of the tubular body 1 (the back surface of the heat-shrinkable film) or the outer surface of the tubular body 1 (the surface of the heat-shrinkable film). When the display is provided on the inner surface of the cylindrical body 1, it is preferable to use a heat-shrinkable film excellent in transparency in order to make the display visible.

  The electrically read information is stored in a memory provided in the IC chip in accordance with a certain rule. An electrically readable medium (mechanical readable medium) is constituted by an IC chip in which information is stored in such a memory and an antenna portion connected to the IC chip. By providing the IC chip and the antenna portion in a partial area of the cylindrical body 1, a mechanical reading medium 21 is provided in the area. The IC chip and the antenna portion are very thin and have a sheet shape, and are generally called IC cards and are commercially available. For example, by attaching a commercially available IC card to a partial area of the cylindrical body 1, the mechanical reading medium 21 is provided in that area. Alternatively, an antenna portion is formed in a partial region of the cylindrical body 1 by a printing method or the like, and an IC chip is electrically connected to the antenna portion and attached, whereby the mechanical reading medium 21 is provided in the region. Is done. The IC chip and the antenna unit are provided on the inner surface of the cylindrical body 1 or the outer surface of the cylindrical body 1.

A region where the mechanical reading medium 21 is provided in the cylindrical body 1 is a reading region 2.
The position of the reading region 2 (in other words, the position where the mechanical reading medium 21 is provided) is not particularly limited as long as it is within the surface of the cylindrical body 1, but preferably the surface of the cylindrical body 1 excluding the seal portion 13. Is within. The seal portion 13 is a portion where the heat-shrinkable film is overlapped and adhered, and cannot be easily broken. Therefore, if the region including the seal portion 13 is defined as the reading region 2, the reading region 2 is sufficient when the tampering is opened. There is a possibility that it cannot be broken.
In addition, the reading area 2 is formed in the cylindrical body 1 so that the upper edge of the reading area 2 coincides with the lower end of the cap portion of the container or is located below the lower end in the relationship after being attached to the container.
In the illustrated example, the reading area 2 is arranged in a part of the cylindrical body 1 below the circumferential opening auxiliary line described later.

The front view shape of the reading region 2 is not particularly limited, and examples thereof include a substantially polygonal shape such as a substantially rectangular shape, a substantially triangular shape, and a substantially hexagonal shape, a substantially circular shape, and a substantially elliptical shape. The substantially rectangular shape means a substantially rectangular shape or a substantially square shape. In the present invention, “substantially” in the shape in plan view means a shape allowed in the technical field to which the present invention belongs. The “substantially” of the substantially rectangular shape, the substantially triangular shape, and the substantially polygonal shape in plan view includes, for example, a shape in which a corner is chamfered, a shape in which a part of a side is slightly inflated or depressed, and a side is slightly curved. Shapes are included. Further, the “substantially” of the substantially circular shape and the substantially elliptical shape in a plan view includes, for example, a shape in which a part of the circumference is slightly inflated or depressed, and a shape in which a part of the circumference is slightly straight or oblique. It is.
The planar view shape of the reading area 2 is defined by the outer shape of the mechanical reading medium 21. The outer shape of the mechanical reading medium 21 refers to a rough shape defined by connecting the outer edges of the medium. In FIG. 6, the outer shape of the reading region 2 in a plan view is indicated by a one-dot chain line. For example, when the mechanical reading medium 21 is an optical reading display such as a barcode as in the illustrated example, the planar view shape of the reading area 2 is substantially rectangular. The outer shape of the optical reading display is defined by connecting each outer edge of the numeric part and each outer edge of the bar part.
When the mechanical reading medium 21 is an electrically readable medium such as an IC chip and an antenna unit (not shown), the planar view shape of the reading area 2 is a substantially rectangular shape, a substantially circular shape, or a substantially circular shape. For example, an elliptical shape. The outline of a medium including such an IC chip and an antenna unit is usually defined by connecting the outer edges of the antenna unit.

  As in the illustrated example, when the mechanical reading medium 21 is a barcode, the barcode is arranged so that the longitudinal direction of the bar portion 21 a of the barcode is parallel to the circumferential direction of the cylindrical body 1. However, the longitudinal direction of the bar portion 21 a of the barcode may be arranged so as to be inclined with respect to the circumferential direction of the cylindrical body 1, or arranged so as to be parallel to the axial direction of the cylindrical body 1. May be.

  The tubular body 1 may be provided with a design print layer as necessary (the design print layer is not shown). The heat-shrinkable film may be either transparent or non-transparent, but it is designed on the back side of the film (the back side of the heat-shrinkable film is the inner surface when it is made into the cylindrical body 1). When providing a printing layer, the thing excellent in transparency is used. In the present specification, transparent (colorless transparent or colored transparent) refers to a case where the total light transmittance is 70% or more, preferably 80% or more, more preferably 90% or more. However, the total light transmittance refers to a value measured by a measurement method based on JIS K 7361 (a test method for the total light transmittance of a plastic-transparent material).

The tubular body 1 is formed with a breaking auxiliary line.
The breaking auxiliary line is a line formed in the cylindrical body 1 in order to make the cylindrical body 1 easy to cut. Examples of the auxiliary line for fracture include a perforation line, a cut line, and a half cut line.
The perforation line is a line in which through-hole portions penetrating in the thickness direction of the heat-shrinkable film (tubular body 1) are intermittently connected like a stitch mark of a sewing needle. That is, the perforation line is a line formed by alternately connecting the through-hole portions and the non-through portions. The perforation line can be thought of as a single line as a whole, with a plurality of through-hole portions arranged through non-through portions. Examples of the plan view shape of one through hole portion of the perforation line include a substantially circular shape or a substantially elliptical shape (pinhole shape), an elongated linear shape, a V shape, a Y shape, and the like. FIG. 6 illustrates a perforation line having a pinhole-shaped through hole.

The cut line is a cut having a predetermined length penetrating in the thickness direction of the heat-shrinkable film (tubular body 1). The shape of the cut line in plan view is an elongated line shape, a V shape, or the like.
The perforated through-hole portion and the cut line are common in that both penetrate through the cylindrical body 1 in the thickness direction, but the length of the cut line is larger than the length of the perforated through-hole portion. The point is different. The length of the perforated through-hole portion refers to the length in the direction in which the perforated line extends, and the length of the non-penetrated portion of the perforated line is the length of the two through-hole portions existing on both sides of the target non-penetrated portion. The shortest straight line length. The length of the cut line refers to the straight line length between both ends of the target cut line.
The half-cut line is a line that does not penetrate in the thickness direction of the heat-shrinkable film (tubular body 1) and is continuous with a notch cut into a substantially V shape.

Further, an opening auxiliary line is formed in the surface of the cylindrical body 1.
The opening auxiliary line is a line formed on the cylindrical body 1 so that the cylindrical body 1 can be easily cut when the cap seal B is opened.
In this respect, the breaking auxiliary line and the opening auxiliary line are common in that the cylindrical body 1 is provided to be easily cut, but the breaking auxiliary line is formed with the intention of breaking when it is tampered with. On the other hand, the opening auxiliary line is an auxiliary line that the purchaser of the container with the cap seal intends to use when the cap seal is properly opened. In other words, the breaking auxiliary line is an auxiliary line formed for the purpose of detecting unauthorized opening, and the opening auxiliary line is an auxiliary line formed for the purpose of regular opening.
Examples of the auxiliary opening line include the perforation line, the cut line, and the half cut line as described above.
One or a plurality of the opening auxiliary line and the breaking auxiliary line are provided independently. A perforation line is preferably used as the opening auxiliary line, and a perforation line or a cut line, or a combination of a perforation line and a cut line is preferably used as the break auxiliary line.
Specifically, the cylindrical body 1 is formed with an opening auxiliary line 41 extending in the axial direction, an opening auxiliary line 42 extending in the circumferential direction, and a breaking auxiliary line 3. Hereinafter, the opening auxiliary line 41 extending in the axial direction is referred to as “axial opening auxiliary line 41”, and the opening auxiliary line 42 extending in the circumferential direction is referred to as “circumferential opening auxiliary line 42”.

The shaft opening auxiliary line 41 is extended in the axial direction of the cylindrical body 1 as a pair of left and right. The shaft opening auxiliary line 41 may be extended while being inclined with respect to the axial direction, or may be extended in parallel with the axial direction. In the illustrated example, the pair of auxiliary shaft-opening lines 41 are inclined and extended with respect to the axial direction so that the circumferential distance between the two lines decreases toward the lower side. The shaft opening auxiliary line 41 is formed between the upper edge and the lower edge of the cylindrical body 1. For example, the shaft opening auxiliary line 41 may be formed from the upper edge to the lower edge of the tubular body 1, or may be formed from the upper edge of the tubular body 1 to the middle portion in the axial direction. Alternatively, it may be formed from the upper part (this upper part does not include the upper edge of the cylindrical body 1 and refers to the part away from the upper edge) to the lower edge, or it may be cylindrical. It may be formed from the upper part of the body 1 to the lower part (this lower part does not include the lower edge of the cylindrical body 1 and refers to a part away from the lower edge). In the illustrated example, the shaft opening auxiliary line 41 is formed from the upper edge of the cylindrical body 1 to the middle portion in the axial direction.
Moreover, the case where a perforation line is used as the auxiliary shaft opening line 41 is shown.
The length of the through hole portion of the shaft opening auxiliary line 41 (perforation line) can be appropriately set, for example, 0.5 mm to 2.5 mm, and the length of the non-through portion of the shaft opening auxiliary line 41 is It can set suitably, for example, is 0.5 mm-2.5 mm.

The circumferential opening auxiliary line 42 extends in the circumferential direction of the cylindrical body 1. Although the circumferential opening auxiliary line 42 may be inclined and extended with respect to the circumferential direction, preferably, the circumferential opening auxiliary line 42 is connected to the circumferential direction of the tubular body 1 as in the illustrated example. It extends in parallel.
The circumferential opening auxiliary line 42 is formed at a position away from the upper edge of the cylindrical body 1. The circumferential opening auxiliary line 42 may be formed in the entire circumferential direction, or may be formed in the circumferential direction except for a part thereof. In the example of illustration, it forms in the whole circumferential direction except the area | region 19 pinched | interposed by the auxiliary | assistant line 42 for circumferential opening, and the said auxiliary | assistant line 41 for shaft opening 41,41. Further, both ends of the circumferential opening auxiliary line 42 are connected to the lower end of the shaft opening auxiliary line 41, respectively. Two regions 19 sandwiched between the pair of auxiliary shaft-opening lines 41 can be considered in the circumferential direction of the cylindrical body 1, but here indicate a narrow region. However, the circumferential opening auxiliary line 42 is not limited to being formed in the entire circumferential direction in the range excluding the region 19, and may be formed in a part of the circumferential direction in the range excluding the region 19.
An opening cut 43 is formed in the narrow region 19 as necessary. The opening cut line 43 is connected to the lower ends of the pair of shaft opening auxiliary lines 41 and 41 and is formed on an extension of the circumferential opening auxiliary line 42, for example. The opening cut 43 is a cut having a predetermined length penetrating in the thickness direction of the tubular body 1, similarly to the cut line.
Further, a case where a perforation line is used as the circumferential opening auxiliary line 42 is illustrated.
The length of the through-hole part of the circumferential opening auxiliary line 42 (perforation line) can be set as appropriate, for example, 0.3 mm to 2.5 mm, and the length of the non-penetrating part of the circumferential opening auxiliary line 42 is It can set suitably, for example, is 0.5 mm-2.8 mm.

The breaking auxiliary line 3 is arranged so as to cause a break in the reading area 2 when tampering is opened.
That is, the breaking auxiliary line 3 is arranged in the plane of the cylindrical body 1 such that a virtual extension line of the breaking auxiliary line 3 intersects one edge of the reading region 2.
One edge of the reading area 2 is one of the sides forming the shape of the reading area 2 in plan view.
The virtual extension line only needs to cross at least one edge of the reading region 2, and may, for example, cross two edges (when the virtual extension line is drawn long, for example, as shown in FIG. 6). The two edges to intersect the left and right edges of the reading area).
Specifically, the breaking auxiliary line 3 is extended in the circumferential direction of the cylindrical body 1, for example. The breaking auxiliary line 3 may be extended while being inclined with respect to the circumferential direction, or may be extended in parallel with the circumferential direction of the tubular body 1.
As the auxiliary line 3 for breaking, at least one selected from a perforation line, a cut line, and a half cut line is used. In the illustrated example, the breaking auxiliary line 3 is a combination of a perforation line and a cut line.
The first breaking auxiliary line 31 is a perforated line, and the second breaking auxiliary line 32 is a cut line. Here, the breaking auxiliary line 3 includes a first breaking auxiliary line 31 and a second breaking auxiliary line 32.
The first breaking auxiliary line 31 extends in parallel with the circumferential direction of the cylindrical body 1, and the second breaking auxiliary line 32 also extends in parallel with the circumferential direction of the cylindrical body 1.

The first breaking auxiliary line 31 is disposed below the circumferential opening auxiliary line 42. The distance between the first breaking auxiliary line 31 and the circumferential opening auxiliary line 42 is not particularly limited, but if the breaking auxiliary line 3 is too far from the circumferential opening auxiliary line 42, the breaking auxiliary line at the time of illegal opening There is a possibility that breakage may occur in the circumferential opening auxiliary line 42 without breaking from 3. From this viewpoint, the distance H between the first breaking auxiliary line 31 and the circumferential opening auxiliary line 42 is preferably 30 mm or less, more preferably 20 mm or less, and further preferably 15 mm or less. On the other hand, if the distance is too small, the breaking auxiliary line 3 and the circumferential opening auxiliary line 42 substantially overlap each other, making it difficult to distinguish between the two. From this viewpoint, the distance H is preferably 1 mm or more, more preferably 3 mm or more, and further preferably 5 mm or more.
The distance H between the first breaking auxiliary line 31 and the circumferential opening auxiliary line 42 is a straight line length in the axial direction between the first breaking auxiliary line 31 and the circumferential opening auxiliary line 42 as shown in FIG. (Spacing between both lines in the axial direction). If the distance is not uniform in the circumferential direction, it refers to its maximum length.
The first breaking auxiliary line 31 extends in the circumferential direction from the left side of the reading area 2 to the right side of the reading area 2 except for the reading area 2. Therefore, the left end portion and the right end portion of the first breaking auxiliary line 31 are disposed near the left edge 2a and the right edge 2b of the reading area 2. For example, the first breaking auxiliary line 31 is formed over the circumference of the cylindrical body 1 × 9/10 to the circumference of the cylindrical body 1 × about 1/10.

For example, the second breaking auxiliary line 32 is formed on each of the left side and the right side of the reading region 2. The second breaking auxiliary line 32 is connected to the left end portion and the right end portion of the first breaking auxiliary line 31, respectively, and extends in parallel with the circumferential direction of the cylindrical body 1 with the end portion as a starting point. When the left end portion and the right end portion of the first breaking auxiliary line 31 are perforated through-hole portions, the second breaking auxiliary line 32 is formed to have one non-penetrating portion from each end portion. ing. Moreover, the 2nd auxiliary | assistant line 32 for a fracture | rupture is formed in linear form. However, the second breaking auxiliary line 32 may be formed in a curved shape or a bent shape (the bent shape includes a dogleg shape or a zigzag shape).
The end of the second breaking auxiliary line 32 is disposed at or near the edge of the reading area 2. In the illustrated example, the end of the second breaking auxiliary line 32 is disposed in the vicinity of the edge of the reading region 2. Here, “near” in this specification includes, for example, a case where the distance between a certain part and another part is 5 mm or less. The end of the second breaking auxiliary line 32 is disposed in the vicinity of the edge of the reading area 2. The distance between the end of the second breaking auxiliary line 32 and the edge of the reading area 2 (here The distance at (refers to the straight line length between the end and the edge) is 5 mm or less. Further, the fact that the end portion is arranged at the edge of the reading region 2 means that the end portion of the breaking auxiliary line 3 overlaps or slightly intersects with the edge of the reading region 2 although not particularly illustrated.

  The second breaking auxiliary line 32 is arranged so that its virtual extension line intersects the edge of the reading region 2. It should be noted that no breaking auxiliary line is formed on the virtual extension line. In FIG. 6, the virtual extension line of the breaking auxiliary line 3 is shown by a two-dot chain line. The virtual extension line refers to a virtual straight line drawn from the end portion of the breaking auxiliary line 3 in parallel with the extending direction of the breaking auxiliary line 3. The term “intersecting” means non-parallel. In the illustrated example, the virtual extension line of the second breaking auxiliary line 32 intersects the edge extending in the axial direction among the edges of the reading region 2.

Specifically, the virtual extension line from the left second auxiliary line for breaking 32 whose end is disposed in the vicinity of the left edge 2 a of the reading area 2 is the left edge 2 a extending in the axial direction among the edges of the reading area 2. It intersects the middle part and the middle part of the right edge 2b (in other words, the virtual extension line passes from the left edge 2a through the plane of the reading region 2 to the right edge 2b). The virtual extension line from the right second auxiliary line for breaking 32, the end of which is arranged in the vicinity of the right edge 2b of the reading area 2, is the middle part of the right edge 2b extending in the axial direction among the edges of the reading area 2. And the middle of the left edge 2a (in other words, the virtual extension line passes from the right edge 2b to the left edge 2a through the reading area 2). The virtual extension line divides the reading area 2 into two areas. Although not shown, an imaginary extension line from the left second auxiliary line for breaking 32 whose end is located at the left edge 2a of the reading region 2 passes through the surface of the reading region 2 and extends in the axial direction. A virtual extension line from the right second auxiliary line for breaking 32, which intersects the middle of the extending right edge 2b and whose end is arranged at the right edge 2b of the reading area 2, passes through the plane of the reading area 2. Crossing the middle of the left edge 2a extending in the axial direction.
Further, the angle of the virtual extension line with respect to the edge of the reading area 2 is not particularly limited. However, as shown in the example of the drawing, one edge of the substantially rectangular reading area 2 is parallel to the axial direction and the second auxiliary breaker When the line 32 is formed in parallel to the circumferential direction of the cylindrical body 1, the angle is 90 degrees.
In the illustrated example, the virtual extension line is parallel to the longitudinal direction of the bar portion 21a.

The film breakability of the first breaking auxiliary line 31 and the circumferential opening auxiliary line 42 may be the same or either one may be higher, but the first breaking auxiliary line 31 is a film than the circumferential opening auxiliary line 42. It is preferable that cutting property is high. High film cutability means that two auxiliary lines to be compared are formed on the same film in the same length and in the same direction, and when the film is torn along the auxiliary lines, the film is cut with a weak force Say.
When the first breaking auxiliary line 31 is a perforation line, the length of the through-hole portion can be appropriately set, for example, 0.5 mm to 2.8 mm, and the non-penetrating portion of the first breaking auxiliary line 31 Can be set as appropriate, and is, for example, 0.3 mm to 2.5 mm. When the first breaking auxiliary line 31 and the circumferential unsealing auxiliary line 42 are both perforated lines, as a method of constructing the first breaking auxiliary line 31 having a high film cutting property, (a) for first breaking The length of the through hole portion of the auxiliary line 31 (perforated line) is made larger than the length of the through hole portion of the circumferential opening auxiliary line 42, and (b) the length of the non-through portion of the first breaking auxiliary line 31 is set. (C) The length of the through hole portion of the first breaking auxiliary line 31 is made larger than the length of the through hole portion of the peripheral opening auxiliary line 42. In addition, the length of the non-penetrating portion of the first breaking auxiliary line 31 is made smaller than the length of the non-penetrating portion of the circumferential opening auxiliary wire 42.
The length of the second breaking auxiliary line 32 (cut line) is not particularly limited. For example, the length is larger than the maximum length of the through-hole portion of the first breaking auxiliary line 31, and is preferably 3 mm or more. Preferably, it is 4 mm or more, More preferably, it is 5 mm or more.

In the illustrated example, the shaft opening auxiliary line 41 is arranged such that its virtual extension line intersects the edge of the reading region 2. In the illustrated example, the virtual extension line of the shaft opening auxiliary line 41 intersects edges (upper edge and lower edge) extending in the circumferential direction among the edges of the reading region 2. It can be said that the shaft opening auxiliary line 41 also serves as a breaking auxiliary line.
The shaft opening auxiliary line 41 in the illustrated example is conceptually a breaking auxiliary line, but this shaft opening auxiliary line 41 is planned to be used when the attached cap seal is properly opened. Therefore, it is included in the category of the opening auxiliary line here.

The shaft opening auxiliary line 41, the circumferential opening auxiliary line 42, and the breaking auxiliary line 3 are, as will be described later, a circumferential opening auxiliary line when the cap seal A is put on the cap portion of the container and heat-shrink mounted. It forms in the cylindrical body 1 so that the container with a cap seal in which 42 is arrange | positioned in the predetermined position of the container is obtained. Therefore, the size of the cylindrical body 1 and the specific arrangement of the shaft opening auxiliary line 41, the circumferential opening auxiliary line 42, and the breaking auxiliary line 3 with respect to the cylindrical body 1 depend on the shape and size of the cap portion of the container. It is designed appropriately according to the dimensions and the like.
In addition, the shaft opening auxiliary line 41, the circumferential opening auxiliary line 42, and the breaking auxiliary line 3 are not formed in the plane of the reading area 2, and the reading area 2 remains as a film. Since the shaft opening auxiliary line 41 and the like are not formed in the plane of the reading area 2, the information on the mechanical reading medium 21 can be read by the reader without any trouble.

  The cap seal A can be obtained, for example, as follows. After producing the cylindrical body 1 using the heat-shrinkable film provided with the mechanical reading medium 21, the cylindrical body 1 is folded into a flat shape with the center portion in the width direction of the mechanical reading medium 21 being a fold. By engraving the auxiliary opening 41 for the shaft opening, the auxiliary auxiliary line 42 for opening the circumference and the auxiliary auxiliary line 3 for breaking from the surface on one side of the flat cylindrical body 1 so as to penetrate the opposite surface, Cap seal A can be obtained. As shown in FIGS. 3 and 4, the cap seal A formed by such a manufacturing method includes a shaft opening auxiliary line 41, a circumferential opening auxiliary line 42, and a breaking auxiliary line 3, which are mechanical reading media. It is formed symmetrically with 21 as the center.

The cap seal A can be attached to the cap part by heat shrinkage while remaining in a cylindrical shape, or can be attached to the cap part by pre-molding, or it can be put on the cap part by pre-molding and applied to the cap part by heat shrinkage. It can also be installed. Pre-formation means that the cap seal A is deformed into a predetermined three-dimensional shape with an inner diameter that can be covered with a cap portion of a container. A top plate may be attached to the cap seal A during the preforming.
In addition, since the concrete structure of the preformed cap seal or the preformed cap seal with a top plate is disclosed in, for example, Japanese Patent Application Laid-Open No. 2006-282246, refer to that.

<Use example of cap seal>
The cap seal A of the present invention is used by being attached to various containers having a cap portion. By heat-shrinking and attaching the cap seal A to the part to be attached of the container including the cap part, the cap part can be protected and it can be proved that the container is not opened.

<Container>
As shown in FIG. 7, the container 6 includes a body portion 61 having a storage space for storing contents, and a cap portion 62 attached to an end portion of the body portion 61.
The outer shape of the body 61 is not particularly limited as long as it can hold the contents therein, and is substantially cylindrical, substantially elliptical, substantially polygonal, such as substantially rectangular or triangular, or substantially triangular pyramidal. The substantially polygonal pyramid shape, the substantially saddle shape, the substantially daruma shape, and the three-dimensional shape obtained by combining these shapes may be used. The “substantially” of the substantially polygonal column shape or the substantially polygonal pyramid shape includes a shape in which a corner is chamfered, a shape in which a part of a side is slightly inflated or depressed, and a shape in which a side is slightly curved. . In addition, “substantially” of a substantially cylindrical shape, a substantially elliptical column shape, a substantially saddle shape, and a substantially daruma shape includes a shape in which a part of an arc is inflated or depressed, a shape in which a part of the arc is a straight line or a diagonal line It is.
Further, the outer shape of the body portion 61 may be a straight body shape or may not be a straight body shape. The straight barrel shape refers to a shape whose circumferential length does not change in the axial direction.

The body portion 61 in the illustrated example has a combined solid shape in which substantially cylindrical portions having different diameters are connected in the axial direction. Accordingly, the body 61 in the illustrated example is not a straight body.
Specifically, the body portion 61 in the illustrated example connects the first portion 611 disposed on the lower side, the second portion 612 disposed on the upper side, and the first portion 611 and the second portion 612. An intermediate portion 613. The outer shapes of the first portion 611 and the second portion 612 are both substantially cylindrical (the shape of the cylinder is a straight cylinder and the cross-sectional outer shape in a plane orthogonal to the axial direction is substantially circular). Is smaller than the circumference of the first portion 611. The intermediate portion 613 has a gradually decreasing circumference as it goes upward (the cross-sectional outer shape is not substantially straight and has a substantially circular cross-section on a plane orthogonal to the axial direction).

  The body portion 61 includes a bottom surface portion 63, and the container 6 can stand on the bottom surface portion 63. The contents stored in the torso 61 are not particularly limited. For example, beverages such as alcohols, water, milk, coffee, liquid seasonings such as soy sauce and soup, granular seasonings, shampoos, body soaps, etc. Sanitary goods.

A spout is opened at the upper end of the body 61 (the second portion 612 of the body 61). The spout is in communication with the storage space of the body portion 61. In order to open and close the spout, a cap portion 62 is detachably attached to the upper end portion of the body portion 61. The cap part 62 in the illustrated example is screwed to the outside of the body part 61 by a screw action.
As the outer shape of the cap part 62, various shapes exemplified by the body part 61 can be adopted. Further, the outer shape of the cap part 62 may be a straight body shape or may not be a straight body shape. In addition, the cap part 62 may be equipped with accessories, such as a tube part and a pump part for pouring out the contents (not shown), for example.
The outer shape of the cap portion 62 in the illustrated example is substantially cylindrical and has a straight body shape. Further, the upper surface 621 of the cap portion 62 in the illustrated example that is attached to the body portion 61 by the screw action and does not include the above-described accessory is closed. A female screw portion is formed on the inner peripheral surface of the cap portion 62, and a corresponding male screw portion is formed on the outer peripheral surface of the upper end portion of the trunk portion 61.
The cap 62 can be detached from the body 61 when it is turned in the opening direction, and can be attached to the body 61 when turned in the closing direction. The opening direction of the cap part 62 in the illustrated example is a counterclockwise direction when viewed from above. However, the opening direction may be a clockwise direction.

The circumferential length of the cap portion 62 is not particularly limited. However, if it is too small, it may not break at the first and second breakage auxiliary lines 32 at the time of unauthorized opening, and is, for example, 50 mm or more, preferably It is 60 mm or more. The upper limit of the circumferential length of the cap portion 62 is not particularly limited, but is generally 50 cm or less and preferably 40 cm or less as a practical numerical value. In addition, when the circumference of the cap part 62 is not constant in the axial direction (for example, in the case of the cap part 62 not having a straight body shape), the circumference of the cap part 62 means the maximum circumference. To do. The height of cap portion 62 (the length of cap portion 62 in the axial direction) is not particularly limited, and is, for example, 5 mm to 10 cm.
Further, the circumferential length of the body portion 61 is not particularly limited, and may be the same as the circumferential length of the cap portion 62 or may be smaller or larger than the circumferential length of the cap portion 62.
In the illustrated example of the container 6, the circumference of the cap portion 62 and the circumference of the second portion 612 of the body portion 61 to which the cap portion 62 is attached are substantially the same. In other words, the outer shape over the cap part 62 and the second part 612 is a straight body.
Moreover, the material of the trunk | drum 61 and the cap part 62 is not specifically limited, Glass, a synthetic resin, a metal, earthenware etc. are mentioned each independently.

<Container with cap seal>
As shown in FIGS. 8 and 9, the container C with a cap seal includes a container 6 having a cap portion 62 and a cap seal B which is heat-shrink mounted on a mounting portion including the cap portion 62 of the container 6. Have. The attached portion is other than the cap portion 62 and the cap portion (a part or all of the trunk portion 61), and the cap seal B is attached across the cap portion 62 and the portion other than the cap portion.
In such a container C with a cap seal, the breaking auxiliary line 3 corresponds to the body part 61 of the container 6, the shaft opening auxiliary line 41 corresponds to the cap part 62, and the circumferential opening auxiliary line 42 is the cap part. A cap seal B is attached corresponding to the lower end of 62 or the vicinity of the upper side or the lower side of the lower end.
Regarding the mounting position in the relationship between the reading area 2 and the cap portion 62, the cap seal B is mounted such that the upper edge of the reading area 2 coincides with the lower end of the cap section 62 or is positioned below the lower end. It is preferable that the reading area 2 is mounted so that the upper edge thereof is located within a predetermined range below the lower end of the cap portion 62. The predetermined range is preferably in the range of 1 mm to 30 mm below the lower end of the cap part 62, more preferably 3 mm to 20 mm, and even more preferably 5 mm to 15 mm.

As for the mounting position in the relationship between the breaking auxiliary line 3 and the cap part 62, the cap seal B is mounted so that the breaking auxiliary line 3 coincides with the lower end of the cap part 62 or is positioned below the lower end. It is preferable that the breaking auxiliary line 3 is mounted so as to be located within a predetermined range below the lower end of the cap portion 62. The predetermined range is preferably in the range of 1 mm to 30 mm below the lower end of the cap part 62, more preferably 3 mm to 20 mm, and even more preferably 5 mm to 15 mm.
In addition, the cap seal B is substantially in close contact with the outer surface of the mounted portion of the container 6 as a whole. Further, the upper end portion of the cap seal B is bent so as to be in close contact with the upper surface 621 of the cap portion 62. However, the cap seal B may be mounted so that the upper end portion of the cap seal B is in close contact with the outer peripheral surface of the cap portion 62 (not bent on the upper surface of the cap portion 62).

Such a container C with a cap seal can be obtained by mounting the cap seal A or a preformed cap seal on a mounting site including the cap portion 62 of the container 6.
Specifically, the cap seal A (or a preformed cap seal) is placed on the upper portions of the cap portion 62 and the second portion of the body portion 61 of the container 6. At this time, the circumferential opening auxiliary line 42 is positioned and covered so as to correspond to the lower end of the cap portion 62 or the vicinity thereof. And the container C with a cap seal | sticker is obtained by heating the cap seal | sticker A to heat shrink temperature. That is, when the cap seal A covering the mounted portion including the cap portion 62 is heated to, for example, 60 ° C. to 120 ° C., the cylindrical body 1 is thermally contracted in the circumferential direction and is in close contact with the container 6, and FIGS. A container C with a cap seal as shown in FIG.

  Note that, after the cap seal A is attached to the container 6, the dimensional change in the circumferential direction is relatively large while the dimensional change in the axial direction is relatively small or substantially unchanged in the axial direction. This relies on the heat shrinkage rate of the heat shrinkable film constituting the cylindrical body 1. The heat shrinkage rate of the cap seal B at the time of mounting is [{periphery length of the cap seal A (tubular body 1) before heat shrinking−perimeter length of the portion to which the container 6 is attached} / cap seal A before heat shrinking ( Perimeter of cylindrical body 1)] × 100.

  Since the cap seal A is reduced in diameter in the circumferential direction after being attached to the container 6, the perforation line (the circumferential opening auxiliary line 42 and the first breaking auxiliary line 31 extending in the circumferential direction). The length of the through-hole portion and the length of the non-penetrating portion, the length of the cut line (second breaking auxiliary line 32 extending in the circumferential direction), etc. are the respective heat shrinkage rates when the cap seal B is mounted. Decrease accordingly. The amount of change in the length of the through-hole portion of the perforation line of the cap seal A before heat shrinkage (how much the length becomes smaller after heat shrinkage) varies depending on the heat shrinkage rate of the cap seal B, In general, the lower limit value of the amount of change in the length of the cap seal B after the heat shrinkage is 0.5 times, and the upper limit value thereof is less than 1 time. For example, when the length of the perforated through-hole portion is 0.5 mm to 2.5 mm, the lower limit value of the length of the through-hole portion is 0.5 mm × 0.5 times after the heat shrinkage mounting. Thus, the upper limit of the length may be less than 2.5 mm × 1 time. Preferably, the amount of change in the length of the cap seal B after the heat shrinking is 0.6 to 0.95 times. In this case, the length of the through-hole portion of the perforation line after heat shrinkage may be lower limit value x 0.6 times to upper limit value x 0.95 before heat shrinkage. It is preferable that the lengths of the through hole portion and the non-through portion of the perforation line extending in the axial direction are substantially the same before and after thermal contraction.

<Use of containers with cap seals>
When the container C with a cap seal is normally opened, the upper end of the region 19 sandwiched between the pair of shaft opening auxiliary lines 41 is picked with a finger, and the cap seal B The region 19 is cut out from the upper part of the. Since the opening cut 43 is formed at the lower end of the shaft opening auxiliary line 41, the region 19 can be easily cut and removed. Thereafter, the upper part of the cap seal B is cut off using the circumferential opening auxiliary line 42 (see FIG. 10). By completely removing the upper part of the cap seal B, the cap part 62 can be completely exposed. After that, the cap part 62 can be removed and the contents in the container 6 can be taken out.

On the other hand, it is also assumed that the cap seal B is illegally opened for the purpose of mischief, for example, without purchasing a product and performing regular opening. In this regard, when the cap seal B of the container C with a cap seal of the present invention is tampered with, the reading area 2 is broken and the mechanical reading medium 21 is divided. it can.
Specifically, when the upper part of the cap seal B corresponding to the cap part 62 is gripped by hand and rotated together with the cap part 62 in the opening direction, as shown in FIG. Furthermore, a crack is generated in the circumferential direction from the end of the breaking auxiliary line 3 (second breaking auxiliary line 32), and the reading area 2 is broken. At the time of this unauthorized opening, the cap seal B is twisted between the upper part and the lower part thereof, so that the break may occur along not only the breaking auxiliary line 3 but also a part of the circumferential opening auxiliary line 42. However, since it breaks at the breaking auxiliary line 3, the reading area 2 is broken.

In the cap seal B of the present invention, the breaking auxiliary line 3 is formed so that the virtual extension line of the breaking auxiliary line 3 intersects the edge of the reading area 2. To the reading area 2 and the mechanical reading medium 21 provided in the reading area 2 is divided.
The information on the mechanical reading medium 21 divided in this way is difficult to read by a reader (mechanical reading device), and it is possible to detect the presence or absence of unauthorized opening in a cash register operation in store sales. In particular, as in the illustrated example, when the mechanical reading medium 21 is a bar code and the breaking auxiliary line 3 and its virtual extension line extend in the longitudinal direction of the bar portion 21a of the bar code, a plurality of In the bar part 21a adjacent to the bar code in which the bar parts 21a are arranged in multiple stages, the bar code is divided (see FIG. 11). Thus, the barcode in which the adjacent bar portions 21a are divided cannot be read by a reader, and the presence or absence of the unauthorized opening can be reliably detected.
By using the cap seal A of the present invention, it is possible to detect the presence or absence of unauthorized opening not only by human eyes but also mechanically, so that it is easy to detect mischief, and it is possible to prevent mischief.

The present invention is not limited to the first embodiment and can be variously modified.
Hereinafter, various other embodiments of the present invention will be described, but the description of the same configurations and effects as those of the first embodiment will be omitted (assuming that the description has been made), and the terms and symbols will be used as they are.

[Second Embodiment]
In the first embodiment, the second breaking auxiliary line 32 is formed in parallel with the circumferential direction of the cylindrical body 1. For example, as shown in FIG. 12, the first breaking auxiliary line 31 is a cylinder. It may be formed in parallel with the circumferential direction of the cylindrical body 1, and the second breaking auxiliary line 32 may be inclined with respect to the circumferential direction of the cylindrical body 1 and extended in the circumferential direction. In this case, the virtual extension line of the second breaking auxiliary line 32 forms an acute angle with respect to the edge of the reading region 2.
The angle of inclination of the second breaking auxiliary line 32 with respect to the circumferential direction is not particularly limited as long as it is an acute angle and the virtual extension line intersects the edge of the reading region 2. Sometimes, the mechanical reading medium 21 may not be sufficiently divided. From this viewpoint, the inclination angle is preferably greater than 0 degree and not greater than 60 degrees, and more preferably greater than 0 degree and not greater than 45 degrees. In the illustrated example, the second breaking auxiliary line 32 is inclined downward toward the reading area 2, but may be inclined upward toward the reading area 2 (not shown). ). Furthermore, from the end portion of the first breaking auxiliary line 31, a second breaking auxiliary line 32 that is inclined downward toward the reading region 2 and a second breaking auxiliary that is inclined upward toward the reading region 2. Each of the lines 32 may be formed (not shown).

FIG. 13 shows the cap seal A in which the first breaking auxiliary line 31 inclined with respect to the circumferential direction of the cylindrical body 1 is formed. In the illustrated example, the second breaking auxiliary line 32 is disposed on the inclined virtual extension line of the first breaking auxiliary line 31, and the virtual extension line of the second breaking auxiliary line 32 is at the edge of the reading region 2. Crossed.
In this case, the second breaking auxiliary line 32 is not limited to being inclined downward, and may be parallel to the circumferential direction, or may be inclined upward.

  Further, in the first embodiment, the first breaking auxiliary line 31 is formed relatively long in the circumferential direction of the cylindrical body 1. For example, as shown in FIG. 31 may be relatively short.

In particular, it is more preferable that the end portion of the first breaking auxiliary line 31 is formed in the vicinity of the circumferential opening auxiliary line 42. By forming in this way, at the time of unauthorized opening, a breakage occurs substantially along the circumferential opening auxiliary line 42 and the breaking auxiliary line 3, and the reading region 2 is broken by a crack from the breakage.

Further, in the first embodiment, the breaking auxiliary line 3 is formed in a left-right symmetric shape with the center portion in the width direction of the mechanical reading medium 21 as a center line, but is formed in a left-right symmetric shape. Without being limited thereto, the auxiliary breaking lines 3 may be formed asymmetrically on the left side and the right side around the mechanical reading medium 21 (not shown).
Further, as shown in FIG. 15, the breaking auxiliary line 3 may be formed only on the left side (or on the right side) with the mechanical reading medium 21 as the center. The cap seal A in which the breaking auxiliary line 3 is formed only on the left side as shown in FIG. 15 is preferably mounted on a container having a cap portion 62 whose opening direction is counterclockwise when viewed from above. . This is because if the cap portion is turned in the direction of opening at the time of unauthorized opening, a crack is easily generated from the end portion of the breaking auxiliary wire 3 toward the reading region 2.
As described above, the method of forming the breaking auxiliary line 3 in the left-right asymmetric form or forming the breaking auxiliary line 3 only on one side includes (a) the breaking auxiliary line 3 in advance at a predetermined position of the heat-shrinkable film ( If necessary, the shaft opening auxiliary line 41 and the circumferential opening auxiliary line 42 are formed at the same time, and are formed into a cylindrical shape to form the cylindrical body 1. (b) After the cylindrical body 1 is formed, Inserting a penetration preventing plate into the cylinder, and forming the auxiliary line for breaking 3 from one side of the cylindrical body 1 (at the same time, the auxiliary line 41 for opening the shaft and the auxiliary line 42 for opening the circumference simultaneously) A method is mentioned.

  Further, in the first embodiment, the breaking auxiliary line 3 is formed so that the virtual extension line of the breaking auxiliary line 3 extends in the longitudinal direction of the bar portion 21a of the barcode. 16, the breaking auxiliary line 3 may be formed so that a virtual extension line of the breaking auxiliary line 3 extends in a direction orthogonal to the longitudinal direction of the bar portion 21a of the barcode. In this case, in order to be able to divide the adjacent bar portion 21a of the bar code at the time of tampering, one of the auxiliary lines for breaking 3 '(right side in the illustrated example) is read with its extended virtual line having a bar code. It is preferable to arrange the second auxiliary line for breaking 3 ″ (the left side in the illustrated example) on the lower side (or the upper side) of the bar code so as to cross the edge of the region 2.

In the first embodiment, the circumferential opening auxiliary line 42 and the breaking auxiliary line 3 are formed. However, the circumferential opening auxiliary line 42 may also serve as the breaking auxiliary line 3.
FIG. 17 shows the cap seal A in which the circumferential opening auxiliary line 42, which is an auxiliary line scheduled to be used when the cap seal is normally opened, is also an auxiliary line scheduled to be broken at the time of unauthorized opening. .
In FIG. 17, the circumferential opening auxiliary line 42 is formed in the circumferential direction, but a region (uncut region) in which the opening auxiliary line is not formed is secured in a part of the circumferential direction. The reading area 2 is provided by providing a mechanical reading medium 21 in that area. The end of the circumferential opening auxiliary line 42 is arranged at or near the edge of the reading area 2, and the virtual extension line of the circumferential opening auxiliary line 42 intersects the edge of the reading area 2. .
When a container with a cap seal to which such a cap seal A is attached is tampered with, it is broken along the circumferential opening auxiliary line 42, and the reading region 2 on the extended line is also broken.

In each of the above embodiments, a cut line is used as the second breaking auxiliary line 32, but a perforation line may be used as the second breaking auxiliary line 32 (not shown).
Further, in each of the above embodiments, the shaft opening auxiliary line 41 and the opening cut line 43 are formed in the cylindrical body 1, but these may be omitted as necessary.
Moreover, you may form the auxiliary line for opening other than the auxiliary line for axis | shaft opening, and the auxiliary line for circumference opening in the cylindrical body 1.
