  As described above, in a package that wraps a small container with a heat-shrinkable film, a knob is provided at the edge of the film in order to remove the heat-shrinkable film. Since the heat-shrinkable film is covered so that the edge part extends along the top surface part up to the upper part called the top surface part of the cap of the container, the knob extending from the edge part is in a form along the top surface part. Provided. In order to have this knob part, as described in Patent Document 1, it is necessary to cause it from a state along the top surface part. If the container is small, the knob is also small, which is troublesome, such as taking time to cause this.

  An object of the present invention is to provide a package in which a knob for removing a heat-shrinkable film packaging a small container is easy to pick.

A packaging body according to the present invention includes a body, a container connected to the upper part of the body, and having a reduced diameter part that is reduced in diameter toward the top and the top surface or the top, and the body of the container. Heat shrinkable film covering

The knob part is provided so as to be along the outer peripheral surface of the container body part at a distance, and the knob part is provided to rise upward from the upper end edge part of the heat shrink film, and is provided apart from the reduced diameter part. .

  The package according to the present invention includes a container having a container body and a cap attached to the outlet, a heat-shrinkable film covering the container body and the cap from the container body to the cap, and a heat-shrinkable film. A cap provided at the upper edge of the heat-shrinkable film for removal, and the cap is connected to the cap body and the upper part of the cap body, and has a diameter smaller than the cap body toward the upper side. And the upper edge of the heat-shrinkable film is separated from the upper end of the cap body by a predetermined distance from the outer peripheral surface of the cap body. The knob is provided so as to rise upward from the upper edge of the heat-shrinkable film and to be spaced apart from the cap diameter-reduced portion.

  The package according to the present invention includes a container having a container body and a cap attached to the outlet, a heat-shrinkable film covering the container body and the cap from the container body to the cap, and a heat-shrinkable film. A cap provided on the upper edge of the heat-shrinkable film for removal, the cap has a cap body and a top surface connected to the cap body, and the upper edge of the heat-shrinkable film Is provided at a predetermined distance below the upper end of the cap body so as to be along the outer peripheral surface of the cap body, and the knob is directed upward from the upper edge of the heat shrinkable film. It stands up and is provided apart from the top surface.

  Moreover, the package which concerns on this invention WHEREIN: It is preferable that a knob | pick part has a printing part for rigidity reinforcement in the back surface.

  Further, in the package according to the present invention, the container has a container lower part that is reduced in diameter from the position of the maximum outer diameter toward the bottom, and the heat-shrinkable film is on the outer peripheral surface of the container lower part that is reduced in diameter. It is preferable to reduce the diameter along.

  Further, in the package according to the present invention, the container has an upper part of the container that is reduced in diameter from the position of the maximum outer peripheral diameter toward the top surface part or the top part, and the heat-shrinkable film is formed on the upper part of the container that is reduced in diameter. It is preferable to reduce the diameter along the outer peripheral surface.

  Further, in the package according to the present invention, the heat-shrinkable film includes a horizontal perforation provided along the circumferential direction of the outer peripheral surface of the container, a vertical perforation provided from the knob to the horizontal perforation, It is preferable to have a plurality of slope cuts provided along the perforation and inclined with respect to the arrangement direction of the horizontal perforation.

  Further, in the package according to the present invention, the heat-shrinkable film includes a horizontal perforation provided along the circumferential direction of the outer peripheral surface of the container, a vertical perforation provided from the knob to the horizontal perforation, And an adhesive layer provided on the back surface on the lower end side of the perforation.

  With the above configuration, the packaging body for a container having a trunk portion and a reduced diameter portion that is connected to the upper portion of the trunk portion and has a diameter smaller than the trunk portion toward the upper side to become the top surface portion or the top portion is the trunk portion of the container. Is covered with a heat-shrinkable film, and a knob is provided at the upper edge of the heat-shrinkable film to remove the heat-shrinkable film. Here, the upper edge portion of the heat-shrinkable film is provided along the outer peripheral surface of the container body portion at a predetermined distance below the upper end of the body portion, and the knob portion is heat-shrinkable. It rises upward from the upper edge of the film and is provided away from the reduced diameter portion. In the prior art, since the picking portion is stretched in close contact with the container, it may be difficult to pick, but in comparison with this, the picking portion for removing the heat-shrinkable film for packaging a small container is easy to pick.

  In addition, the packaging body for a container having a container main body and a cap covers the container main body and the cap from the container main body to the cap, and the heat shrinkable film covers the upper edge of the heat shrinkable film to remove the heat shrinkable film. A knob is provided in the part. Here, the upper edge of the heat-shrinkable film is provided so as to be along the outer peripheral surface of the cap body part at a predetermined distance below the upper end of the cap body part. It rises upward from the upper edge of the adhesive film and is provided away from the cap diameter-reduced portion. This makes it easy to pick a knob for removing the heat-shrinkable film that packages the small container.

  In addition, a package having a container body and a cap, and when the cap has a top surface part, the heat shrinkable film covers the container body and the cap from the container body to the cap, and the heat shrinkable film is removed. A knob is provided at the upper edge of the heat-shrinkable film. Here, the upper edge of the heat-shrinkable film is provided so as to be along the outer peripheral surface of the cap body part at a predetermined distance below the upper end of the cap body part. It rises upward from the upper edge of the adhesive film and is provided away from the top surface of the cap. This makes it easy to pick a knob for removing the heat-shrinkable film that packages the small container.

  Further, in the package, since the knob has the rigidity reinforcing printing part on the back surface, the knob is easily separated from the outer peripheral surface of the container and rises more easily than when nothing is provided on the back surface.

  Further, when the container has a container lower part that is reduced in diameter from the position of the maximum outer peripheral diameter toward the bottom part, in the package, the heat-shrinkable film is reduced in diameter along the outer peripheral surface of the container lower part that is reduced in diameter. Therefore, it is possible to prevent the label portion of the heat shrink film from coming out upward until the heat shrink film is removed by perforations or the like.

  In addition, when the container has a container upper portion that is reduced in diameter from the position of the maximum outer diameter toward the top surface portion or the top portion, in the package, the heat-shrinkable film is along the outer peripheral surface of the container upper portion that is reduced in diameter. Since the diameter is reduced, it is possible to prevent the label portion of the heat shrink film from coming out downward until the heat shrink film is removed by perforation or the like.

  Further, in the package, the heat-shrinkable film includes a horizontal perforation provided along the circumferential direction of the outer peripheral surface of the container body, a vertical perforation provided from the knob to the horizontal perforation, and a horizontal perforation. And a plurality of inclined cut lines provided to be inclined with respect to the arrangement direction of the horizontal perforations. If the upper edge of the heat-shrinkable film is provided at a predetermined distance away from the upper end of the cap body in order to stand up away from the outer peripheral surface of the container, heat shrinkage will occur on the upper surface of the cap. The adhesive film is not in close contact. Therefore, depending on the shape of the container, the heat-shrinkable film may be pulled out above the cap. This impairs the protective function of preventing the cap as a package from being intentionally opened by mischief or the like.

  According to the above configuration, if the heat-shrinkable film is intentionally removed, the heat-shrinkable film is irreversibly broken by a plurality of inclined breaks, and it is difficult to restore it to the original state. Accordingly, it is easy to find a prank that breaks only a horizontal perforation without opening a cap or the like and then restores to the original state without breaking the vertical perforation, so that such a prank can be suppressed.

  In the package, the heat-shrinkable film is composed of a horizontal perforation provided along the circumferential direction of the outer peripheral surface of the container body, a vertical perforation provided from the knob to the horizontal perforation, and a horizontal perforation. And an adhesive layer provided on the back surface on the lower end side. Thereby, integration between the heat-shrinkable film and the container can be strengthened, and for example, the heat-shrinkable film is prevented from being pulled out both on the upper side and the lower side of the cap.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following, a small eye drop container will be described as a container to be packaged, but any other container may be used as long as it is packaged with a heat-shrinkable film having a knob. In the following description, the container includes a container body and a cap. However, the container may be a container having no cap and having an upper part of the container body sealed.

  FIG. 1 is a diagram illustrating a state of a package 10 packaged with a heat-shrinkable film having a knob. Here, an eye drop container as a small container 20 is covered with a cylindrical heat-shrinkable film 29 before heat shrinkage, and is shrunk by applying appropriate heating, for example, heating with hot air of about 100 ° C. to about 200 ° C. A package 10 formed by wrapping with a heat-shrinkable film 30 is shown.

  The container 20 is configured to include a container main body 22 that contains eye drops therein, and a cap 24 that is detachably attached to an outlet portion at the top of the container main body 22 by screws. The container 20 is formed of a resin material suitable for the characteristics of eye drops, and has a size of about 30 mm to about 60 mm in height and about 10 mm to about 25 mm in outer diameter. In the example of FIG. 1, considering the ease of handling of the cap 24, the outer diameter of the container body 22 and the outer diameter of the cap 24 are almost the same.

  The cap 24 has a cap body portion having the same outer diameter and a top surface portion which is a flat top portion on the cap body portion. However, from the cap body portion toward the top surface portion, the outer diameter decreases gradually and becomes a reduced diameter portion. The reduced diameter portion is a portion that is connected to the upper portion of the cap body portion and becomes a top surface portion or a top portion by reducing the diameter of the cap body portion upward. In the case of a container that does not have a cap, there is a container body part, which is connected to the upper part of the container body part, and the part which becomes the top surface part or the top part by reducing the diameter from the container body part upward is the container. It becomes a reduced diameter part.

  The heat-shrinkable film 29 before heat shrinkage is a cylindrical film having an inner diameter larger than the maximum outer shape of the container 20, which is covered with the container 20 and contracted by heating under appropriate conditions. It is a film having the property of being attached in close contact with the outer peripheral surface. As another method, a sheet of heat-shrinkable film before heating may be wound around the outer periphery of the container 20. In FIG. 1, the center seal part 32, the horizontal perforation 34, the vertical perforation 36, the knob | pick part 50, and the upper end edge part 48 are shown in the cylindrical heat-shrinkable film 29 before heat shrinkage. Details of these will be described later.

  The heat-shrinkable film 29 before heat-shrinking is heated, and the heat-shrinkage caused by this can be given anisotropy. In the case of FIG. 1, the container 20 moves from the container body 22 to the cap 24. When the direction is the vertical direction and the direction perpendicular to the width direction is the width direction, the heat shrinkage rate in the width direction due to heating is set to be larger than the heat shrinkage rate in the vertical direction in the tubular heat-shrinkable film 29. .

  Examples of the material of the heat-shrinkable film 29 include polyester resins such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyethylene naphthalate (PEN); polyolefin resins such as polyethylene and polypropylene; styrene-butadiene. Polystyrene resins such as copolymers; polyvinyl chloride resins, polyvinylidene chloride resins and the like can be used. These materials can be used alone or in admixture of two or more. Among these, a film made of polystyrene resin, polyester resin, or polyvinyl chloride resin is preferable. These heat-shrinkable films 29 may be composed of either a single layer film or a multilayer film.

  The heat-shrinkable film 29 is stretched in at least one direction (for example, the transverse direction) and exhibits heat-shrinkability in the stretching direction. In the above example, the sheet having the extending direction in the width direction is combined with the center seal portion 32 to form the cylindrical heat-shrinkable film 29. This stretching treatment is carried out using a tenter method, a tube method, or the like, for example, at a temperature of about 70 to 100 ° C., and 2.0 to 8.0 times in the main stretching direction, preferably 3.5 to 6.0. It is performed by stretching about twice. In addition, about 1.1 to 1.5 times can be extended also in the direction orthogonal to the main extending direction.

  The heat shrinkage ratio of the heat-shrinkable film 29 thus stretched in one direction by heating in the main stretching direction is, for example, about 10 to 80%, preferably 20 to 75 at 90 ° C. (immersion in warm water for 10 seconds). %. At this time, the heat shrinkage rate is about −3 to + 10% in the direction orthogonal to the main stretching direction. Here, −3% indicates a thermal expansion of 3%. This heat shrinkage rate can be adjusted by appropriately selecting the stretching conditions such as the type of resin constituting the heat shrinkable film 29 and the stretching ratio. The thickness of the heat-shrinkable film 29 can be selected from the range of, for example, about 10 to 80 μm, preferably about 20 to 60 μm, from the viewpoint of shrinkage stress and cost.

  In the package 10 of FIG. 1, the knob 50 is formed so as to be separated from the outer peripheral surface of the container 20 and rise. For this reason, the upper edge 48 of the heat-shrinkable film 30 after heat-shrinking does not cover the entire upper portion of the container 20 and is below the top surface, which is the top surface of the cap 24, as will be described later. It is set so as to be along the outer peripheral surface of the cap body part at a predetermined distance.

  FIG. 2 shows a state in which the package 10 of FIG. 1 is compared with the package 11 of the prior art. In this figure, the container having the container main body 22 and the cap 24 described with reference to FIG. 1 is a heat-shrinkable film made of the same material, but the upper edge of the container is different in position. (A) is the package 10 demonstrated in FIG. 1, and FIG.2 (b) on the right side is the package 11 of a prior art.

  In the package 10, the position of the upper edge 48 of the heat-shrinkable film is lowered by S from the upper surface of the cap 24 connected to the upper end of the cap body, that is, the upper part of the cap body. It is packaged by a heat-shrinkable film 30 serving as a position. On the other hand, the package 11 according to the prior art is packaged by the heat-shrinkable film 31 whose upper edge 49 covers a part of the top surface of the cap 24. Due to the difference in structure, in the package 10, the knob portion 50 rises apart from the outer peripheral surface of the cap 24 without being along the top surface portion, whereas in the conventional package 11, the knob portion 51 is raised. However, as the upper edge 49 of the heat-shrinkable film 31 covers the top surface portion of the cap 24, it extends along the top surface portion of the cap 24, does not separate from the cap 24, and does not stand up.

  Here, the upper edge of the heat-shrinkable film is the state before the heat shrinkage, as shown in FIG. It is a linear part. In a state where the container is packaged, it is an upper boundary that wraps around the container and is a portion excluding the knob. Therefore, in the package 10 shown in FIG. 2A, the upper edge 48 is an upper boundary that wraps around the outer periphery of the cap 24 and excludes the knob 50. As described above, the cap 24 It is provided so that the outer peripheral surface of the cap trunk | drum which fell only S from the top | upper surface part of this may be followed. On the other hand, in the package 11 of FIG. 2 (b), the upper edge 49 is a boundary between where the top surface of the cap 24 is covered and where it is not covered, excluding the knob 51. As described above, the cap 24 is provided along the top surface portion.

  When the heat-shrinkable film is placed on the container and given appropriate heat, it shrinks and adheres along the outer shape of the container. Accordingly, when the upper edge of the heat-shrinkable film before shrinkage is aligned and heat-shrinked so as to extend above the top surface of the cap 24, the upper edge of the cap 24 is heated. An attempt is made to adhere to the top surface of the cap 24, which is the outer shape. At this time, the knob portion is also arranged in a form extending on the top surface portion of the cap 24 according to the close contact of the upper edge portion. This case is the prior art package 11 shown in the diagram on the right side of FIG.

  When the upper edge of the heat-shrinkable film before shrinkage is heat-shrinked by aligning the upper edge of the heat shrinkable film so that it does not exceed the top surface portion of the cap 24, the upper edge of the cap 24 is heated. It adheres along the side surface of the cap 24 which is the outer shape of. At this time, the knob is arranged in a form extending upward along the side surface of the cap 24 extending vertically upward in accordance with the close contact of the upper end edge with the cap body, and the tip thereof is located above the upper end of the cap body. By exceeding the top surface portion of the cap 24, the cap 24 is separated from the outer peripheral surface of the cap 24 and rises upward. This case is the package 10 shown in the left side of FIG.

  In the above description, it is assumed that the cap 24 has a cylindrical shape, the top portion of which is a flat top surface portion, and the transition from the cylindrical shape to the top surface portion is performed with a very short dimension. There are various types of caps, but in any case, the heat shrinkable film is contracted by heating along the outer shape of the container, so that the upper edge also adheres along the outer shape. For this reason, in order for the knob part to stand apart from the outer peripheral surface of the cap 24 during heat shrinkage, the upper edge of the heat shrinkable film needs to be provided below the upper end of the cap body part. It is. In addition, the setting of the upper edge part about the form of some containers is mentioned later using an example.

  Then, considering the variation in the shape of the cap 24, the variation in the shape of the heat-shrinkable film, etc., it is preferable to arrange the upper end edge with some allowance. 2, the upper edge 48 of the heat-shrinkable film 30 is shown to have a predetermined distance S that is set in advance from the position of the upper end of the cap body. The predetermined distance S can be about 1 mm to about 3 mm, for example.

  Next, the manufacturing method of the heat-shrinkable film 29 before heat shrinking is demonstrated. FIG. 3 shows an example of this. A long sheet-shaped material is rounded into a cylindrical shape in the width direction and overlapped at both ends to be bonded and fixed. This adhesive fixing is sometimes called a center seal. This long cylindrical thing is cut | disconnected to predetermined length, and it is set as the individual heat shrinkable film 29 before a heat shrink. As described above, the sheet-shaped material is used that has been uniaxially stretched at least in the width direction. Also, a wide material is formed, and this is matched with a predetermined cylindrical shape to have a predetermined width. It can be cut into pieces. The longitudinal cut is performed by a straight cut that becomes the upper edge 48, but in order to form the knob 50, a portion is formed in an overhang shape. Accordingly, the shape after cutting and separating individually corresponding to the overhanging portion at the upper edge 48 is a part where the lower end is partially cut away. In addition, in the package 10 of FIG. 1, a mode that the lower end part of the heat-shrinkable film 30 after heat shrinking is partly cut off and the container is peeping is shown.

  FIG. 4 is a detailed view of the heat shrinkable film 29 before heat shrinkage. Here, the thing of the form manufactured with the method of FIG. 3 is shown. In the following, elements similar to those in FIGS. 1 to 3 are denoted by the same reference numerals, and detailed description thereof is omitted. In the following, description will be made using the reference numerals in FIGS. As already briefly described with reference to FIG. 1, the cylindrical heat-shrinkable film 29 is provided with a center seal portion 32, a horizontal perforation 34, a vertical perforation 36, and a knob 50. In FIG. 5, the upper edge 48 is shown.

  As described with reference to FIG. 3, the center seal portion 32 is a portion that is bonded and fixed at both end portions in the width direction in order to round the sheet-like material into a cylindrical shape. Adhesion and fixation can be performed by a method using an adhesive or a solvent, a method by heat sealing using a heat-sensitive adhesive, a method using high-frequency heating, or the like. As shown in the enlarged view A, when the print layer 40 for display or the like is provided on the back surface of the heat-shrinkable film 29, that is, the surface close to the container 20, the print layer is placed at the center seal portion 32. It is preferable not to provide a part. In the example of FIG. 4, the printing layer 40 on the back side of the sheet that comes to the front side is partially omitted.

  As described above, when the heat-shrinkable film 30 that wraps the container 20 is removed, the knob 50 is an overhang provided so that the user can easily grip and pull it. The knob 50 is provided so as to protrude from the upper edge 48 of the heat-shrinkable film 29 before heat shrinkage to a size that can be picked with a finger. The size of the knob 50 can be about 2 mm to about 10 mm in width and about 5 mm to about 20 mm in length of the overhang.

  As shown in the sectional view B showing the adhesion state to the container, it is preferable to provide an appropriate printed layer 40 on the back surface of the knob 50, that is, the surface facing the outer peripheral surface of the container 20. The printed layer 40 functions to reinforce the rigidity of the knob 50 rather than for display. That is, since the printing layer 40 has an appropriate thickness, the thickness of the printed layer 40 increases the rigidity of the entire film of the knob portion 50, so that the knob portion 50 is placed on the outer peripheral side of the container 20 during heat shrinkage. Suppress falling. Moreover, since the printing layer 40 is provided only on the inner surface, the printed layer 40 is easily curled on the outer surface side, and more unlikely to fall on the outer peripheral side of the container.

  The horizontal perforation 34 is a perforation provided over the entire circumference of the cylindrical shape along the width direction of the heat-shrinkable film 29. As the perforation, one that repeats a cut part in which a hole is formed and a joint part between the hole is used. As a means for opening the hole, a rotary blade can be used, and a die cutting or a laser processing machine may be used. The horizontal perforation 34 has a function for separating both the lower side as a label portion for displaying the contents of the container 20 and the upper side as a separation portion for separating the cap 24 when the cap 24 is opened. Part.

  Further, the vertical perforation 36 is a perforation provided from the knob 50 to the horizontal perforation 34, and when the user picks the knob 50 and pulls it toward the bottom of the container 20, the vertical perforation 36 is broken in the vertical direction. It has the function of forming and connecting to the horizontal perforations 34. As the vertical perforations 36, a single perforation may be provided from one side of the knob 50, or a total of two perforations may be provided from both sides of the knob 50.

  As shown in the enlarged view C, the horizontal perforation 34 where the vertical perforations 36 intersect is preferably a long hole 35 having a longer cut portion than the other portions. Thereby, the break of the vertical perforation 36 is easily connected to the horizontal perforation 34. Similarly, as shown in the enlarged view D, the horizontal perforation 34 where the center seal portion 32 intersects is also preferably a long hole 35. This breaks in the circumferential direction and facilitates removal of the heat-shrinkable film.

  A detailed view E indicated by a broken-line circle is a view showing an inclined cut 33 provided to intersect the horizontal perforation 34. The inclined cut line 33 is provided in order to make it difficult to restore to the original state when, for example, only the horizontal perforation 34 is illegally opened by rotating the separating portion without removing it using the vertical perforation 36. It is what That is, at the time of such opening, the heat-shrinkable film 30 that is heat-shrinked and is in close contact with the container 20 at this inclined cut 33 is torn considerably complicatedly, and this is restored to an extent that cannot be visually confirmed. Is difficult. That is, the inclined cut 33 has a function of making the film removal process irreversible. This makes it easier to find mischiefs such as opening a film and opening a cap without intentionally removing the separation, and then restoring it to its original state. Can do.

  Further, an appropriate adhesive layer can be provided on the lower side of the horizontal perforation 34, that is, on the back surface of the portion to be the label portion, that is, on the surface facing the container 20. Thereby, not only at the time of film removal but also before film removal and after film removal, it can prevent that a label part also removes from the container 20 together. That is, before the film is removed, the film itself is prevented from slipping out in any of the vertical directions of the container 20, and after the removal, the label portion is prevented from slipping out in any of the vertical directions of the container 20.

  FIG. 5 to FIG. 8 are diagrams for explaining the setting of the arrangement of the upper edge portion of the heat-shrinkable film for several container forms. In the following, elements similar to those in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, in these illustrations, the printing layer 40, the long hole 35, the inclined cut line 33, the adhesive layer, etc. which were demonstrated in FIG. 4 can each be used according to a use.

  FIG. 5 shows a case in which the container 60 includes a container body 62 having a large outer diameter and a cap 64 having a small outer diameter, and the top of the cap 64 has a flat top surface portion 66. Since this form is substantially the same as in FIGS. 1 and 2, the position of the upper edge 48 of the heat-shrinkable film 30 is separated from the top surface 66 by a predetermined distance from the body portion on the cap 64 side. Is set in place. The horizontal perforation 34 is on the upper side of the container main body 62 so that the label part can be sufficiently displayed and the label part after removing the film and the separation part does not come out downward without being adhered, It is preferable to set it at the shoulder portion where the diameter of the container body is reduced as it goes upward. Moreover, it is preferable that the heat-shrinkable film 30 covers a part of the bottom portion of the container main body 62. By doing in this way, when the knob | pick part 50 is pulled, it can prevent that the heat-shrinkable film 30 falls out upwards.

  FIG. 6 shows a case in which the container main body 72 and the cap 74 have the same outer diameter, and the top of the cap 74 has a flat top surface portion 76 in the container 70. Also in this case, as in FIG. 5, the position of the upper edge 48 of the heat-shrinkable film 30 is set at the body on the cap 74 side at a predetermined distance from the top surface 76 downward. . The horizontal perforation 34 is also preferably set to a neck portion having a smaller outer diameter than the body portion of the container main body 72. Similarly, it is preferable that the heat-shrinkable film 30 covers a part of the bottom of the container main body 72.

  In the structure described with reference to FIGS. 1, 5, and 6, since the knob portion protrudes upward from the uppermost portion of the cap, the knob portion is easy to pinch and is a particularly preferable structure.

  7 is the same as FIG. 5 in that the container 80 includes a container body 82 having a large outer diameter and a cap 84 having a small outer diameter, but the upper part of the cap 84 is a hemisphere 86. It is. In this case, the cap 84 reaches the top of the hemisphere through a reduced diameter portion that is reduced in diameter from the outer diameter of the body portion that is a cylindrical portion. Since the diameter reduction starts from the boundary between the cylindrical portion and the hemisphere, the position of the upper edge 48 of the heat-shrinkable film 30 is predetermined from the upper end of the cap body, which is the position of the boundary between the cylindrical portion and the hemisphere. The distance is set at a position close to the cap body part. The horizontal perforation 34 is preferably set at a shoulder portion having a smaller outer diameter than the body portion of the container body 82. Moreover, it is preferable that the heat-shrinkable film 30 covers a part of the bottom of the container body 82.

  FIG. 8 is the same as FIG. 6 in that the container 90 includes a container body 92 having a large outer diameter and a cap 94 having a small outer diameter, but the cap 94 extends upward in two stages. Thus, the outer diameter is reduced, and the transition between the first stage and the second stage is arcuate. In this case, in the cap 94, the body portion that is the first-stage cylinder portion reaches the top surface portion through the diameter-reduced portion that is reduced in an arc shape from the body portion that is the second-stage cylinder portion. The diameter reduction starts from the position where the first stage cylindrical part starts to move in a circular arc shape from the second stage cylindrical part, that is, the position of the maximum diameter of the circular arc part. Accordingly, the position of the upper edge 48 of the heat-shrinkable film 30 is set at the first-stage cap body at a predetermined distance downward from the position of the maximum diameter of the arc shape that becomes the upper end of the cap body. . The horizontal perforation 34 is preferably set on the shoulder of the container body 92. Moreover, it is preferable that the heat-shrinkable film 30 covers a part of the bottom of the container main body 92.

  As shown in FIGS. 5 to 8, it is preferable that the bottom of the container body is covered along the reduced diameter. As a result, the label portion after the film itself and the separation portion are removed does not come out upward. That is, when the container has a container lower part that is reduced in diameter from the position of the maximum outer diameter toward the bottom, the heat shrinkable film is reduced in diameter along the outer peripheral surface of the container lower part to be reduced in diameter. It is preferable to make it. Thereby, even if the heat-shrinkable film is removed, the label portion of the heat-shrinkable film can be prevented from coming out upward. Also, when the container body has an upper part of the container that reduces the diameter from the position of the maximum outer peripheral diameter toward the top surface or the top, such as the shoulder of the container body, the diameter of the heat-shrinkable film is reduced. It is preferable to reduce the diameter along the outer peripheral surface of the upper part of the container. Thereby, even if the heat-shrinkable film is removed by perforations or the like, the label portion of the heat-shrinkable film can be prevented from falling downward.

  The container body and the cap body should have a cylindrical structure with the same outer diameter in the vertical direction, or a cylindrical structure with an upper outer diameter slightly larger than the lower outer diameter. Is preferred. By doing in this way, a knob part becomes easier to stand up.
