Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container with a cylindrical label and a cylindrical label formed by mounting a heat-shrinkable cylindrical label on a container body such as a PET bottle.
[0002]
[Prior art]
Conventionally, as a soft drink container such as tea and juice, as shown in FIG. 8, a product name and a design are added to a plastic container body 50 such as a polyethylene terephthalate (PET) bottle filled with a soft drink as a content. It is well known that a cylindrical label 53 made of a heat-shrinkable film on which a description such as an explanation of contents is printed is inserted and mounted.
[0003]
After the cylindrical label is peeled and removed, the cylindrical label 53 is provided with a perforation 55 for breaking to improve the peelability so as to collect and recycle the container body 50. There is something.
[0004]
[Problems to be solved by the invention]
When a product in which the cylindrical label 53 is mounted on the container body 50 is marketed and distributed, for example, when the cylindrical labels come into contact with each other, the label 53 is inadvertently broken from the perforation 55 due to the impact. There is a risk that. Therefore, it is necessary to set the perforation 55 to the size of the eye having such a strength that it does not break carelessly. For example, the engraved length is reduced and the interval between the engraved lengths is set large.
[0005]
As a result, the conventional cylindrical label 53 cannot be easily peeled off from the container body 50 by the consumer. In particular, a cylindrical label formed from a heat-shrinkable film made of polyester resin has a problem because it is difficult to tear in the vertical direction (vertical direction of the container body).
[0006]
Further, it is difficult to sell a container (a container filled with contents) in which the label 53 is provided with the perforations 55 (a container filled with contents). That is, when the container is accommodated in the vending machine, the lowermost container is taken out, so that a plurality of upper containers are integrally dropped. In such a case, since the lower container is subjected to an impact, the label 53 may be broken from the perforation 55.
[0007]
Therefore, in order to facilitate the handling of the container provided with the perforation 55 on the cylindrical label 53, or to allow the container to be sold by a vending machine, the perforation is not inadvertently broken, In the present situation, for the recycling of the container body, etc., a device for making the label easily peelable is required.
[0008]
Therefore, the present invention aims to reinforce the broken portion of the cylindrical label by sticking the tape to the label body along the half cut, and to improve the handling of the container, and by pulling the tape, It is an object of the present invention to allow the consumer to easily peel off the label and to provide for collection of the container body.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is made as a container with a cylindrical label and a cylindrical label, and the feature as the container with a cylindrical label is that the container main body 10 has a heat-shrinkable film. cylindrical label body 5 is mounted comprising a line in the cylindrical labeled container breaking means is provided in the cylindrical label body 5, the breaking means, is formed over the entire length to the inner surface of the cylindrical label body 5 A tape cut 15 is attached to the inner surface of the cylindrical label main body 5 so as to cover a portion where the half cut 13 is provided.
[0010]
Incidentally, with the half-cut 13 refers to cuts or grooves of the linear formed without penetrating from the inner surface side of the film to the other side.
[0011]
And since the tape 15 is affixed on the cylindrical label main body 5 so that the part in which the half cut 13 was provided may be covered, the thinning | rupture means can be reinforced. Therefore, when the product with the cylindrical label attached to the container body is distributed on the market or sold by a vending machine, the half-cut 13 of the label is not inadvertently broken.
[0012]
Moreover, when the cylindrical label main body 5 is peeled from the container main body 10, the tape 15 is stuck to the inner surface of the cylindrical label main body 5. Can be easily broken. Furthermore, the half cut 13, by being formed on the inner surface side of the film, since the outer surface of the cylindrical label body 5 is a smooth surface, for example, vending containers cylindrical label body 5 is mounted It is possible to prevent the cylindrical label main body 5 from being caught by a shooter or the like when stored in the container .
[0013]
The cylindrical label is characterized in that a label main body 5 is formed by forming a film 3 having heat shrinkage into a cylindrical shape, and the label main body 5 includes a breaking means provided in a cylindrical label. The breaking means comprises a half-cut 13 for breaking which is a slit or groove formed in the inner surface of the cylindrical label body 5 over the entire length, and the half-cut 13 is formed on the inner surface of the cylindrical label body 5. The tape 15 is attached so as to cover the provided portion.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 show a cylindrical label 1 according to the present invention. The cylindrical label 1 is provided with a label body 5 formed in a cylindrical shape by adhering both end portions of a heat-shrinkable film 3, and the cylindrical label 1 is heated and contracted as shown in FIG. Mounted on the main body 10.
[0015]
The container body 10 is made of plastic such as a polyester resin bottle (PET bottle) such as polyethylene terephthalate having a substantially rectangular cross section.
[0016]
The film 3 has transparency, for example, and is provided with a label printing layer on one side (for example, the inside of a cylindrical label) for displaying, for example, a product name, a design, an explanation about contents, a barcode, and the like. .
[0017]
Examples of the film 3 include a film made of polyester resin, polystyrene resin, polypropylene resin, polyvinyl chloride, etc., having a thickness of 20 μm to 80 μm and mainly having a heat shrinkability in the circumferential direction when formed into a cylindrical shape. It can be used.
[0018]
The label main body 5 is provided, for example, from the shoulder portion of the container main body 10 to the lower edge of the peripheral surface (almost the entire length of the container main body), and the half as a breaking means over the entire length of the label (vertical direction of the container main body) A cut 13 is formed. A method of forming the half cut 13 is not particularly limited, and the cutter blade may be formed by cutting the inner surface side of the label main body 5 halfway or while being pressed with a Thomson blade or the like. In addition, as shown in FIG. 3, when the thickness W of the film 3 is 40-50 micrometers, for example, it is preferable to set the depth D of the half cut 13 to 10-20 micrometers.
[0019]
On the inner surface of the label main body 5, a strip-shaped tear tape 15 having a width of about 2 to 10 mm is attached over the entire length of the label main body so as to cover the half cut 13.
The tear tape is formed of a film having a thickness of about 20 μm to 100 μm, such as polyethylene terephthalate or polypropylene, and is preferably a film uniaxially stretched in the longitudinal direction (longitudinal direction) of the same material as the film of the label body 5, for example, a label When the main body 5 is composed of a polyester-based heat-shrinkable film, it is preferable that the base material of the tear tape 15 and its adhesive are also made of a sheet based on a polyester-based resin. This is because, when the PET bottle is recycled, even if the label main body 5 and the tier tape 15 (its base material and adhesive) are mixed, there is little influence on the recycling.
[0020]
In the production of the label, as shown in FIG. 5, a long film 3 is fed out, a half cut 13 is formed in the feeding direction of the film, and then a tear tape 15 is fed out so as to cover the half cut 13. We stick to film sequentially. And after bonding the both ends of a film and forming in a cylinder shape, it folds in a flat state and winds up in a roll shape.
Furthermore, the roll-shaped film 3 set in the label mounting device is fed out and cut into a predetermined length to form a single cylindrical label, which is then mounted on the container body 10.
[0021]
Further, after the film 3 is cut to a predetermined length, the half cut 13 and the tear tape 15 may be attached.
[0022]
The half cut 13 and the tear tape 15 are located at the corners of the container body 10. The reason why the half-cut 13 and the tape 15 are positioned at the corners in this way is that the film 3 is pulled in the circumferential direction when the cylindrical label 1 fitted to the container body 10 is heated and shrunk. By positioning the half-cut 13 at the corner, the half-cut 13 portion of the film 3 is difficult to be pulled by being in contact with the corner, and the half-cut 13 is not easily broken by the contraction force. Since the tape 15 is located on the inner surface side of the film 3, these do not stand out.
[0023]
For example, when the container is transported from a manufacturing factory to a store or stored in a vending machine in a stacked state, the labels 1 of the containers come into contact with each other. Since the tape 15 is stuck, the half cut 13 is reinforced in the circumferential direction of the label 1 and is not easily broken.
[0024]
In particular, when containers are stored in vending machines, when an operator sequentially puts in containers or takes out the lowermost container at the time of purchasing the container, a plurality of upper containers fall together. Will do. At the time of loading or unloading the container, the container receives an impact, but since the tear tape 15 is stuck along the half cut 13 as described above, the half cut 13 can be prevented from being broken by the impact.
[0025]
Moreover, since the outer surface side of the label main body 5 is a smooth surface , for example , the container can be smoothly conveyed without being caught by a shooter in the vending machine.
[0026]
Next, when peeling off the cylindrical label attached to the container body, if the upper end or lower end of the tear tape 15 is sandwiched and pulled, the film is stretched along the half cut 13 or along both side edges of the tape 15. 3 is broken and the cylindrical label 1 can be easily peeled off.
[0027]
In particular, compared to heat-shrinkable films of polystyrene-based resins and polyvinyl chloride, cylindrical labels made of polyester-based resin films that are substantially uniaxially stretched in the longitudinal direction (the vertical direction of the container) are difficult to cut (tear). Very effective for peeling. The term “substantially laterally uniaxially stretched” means, for example, that the film is stretched 3 to 5 times in the lateral direction and 1.0 to 1.5 times in the longitudinal direction.
[0028]
The present invention is not name limited to the above embodiment. As a reference example, FIG. 6A illustrates a case where the half cut 13 is provided on the outer surface side of the film 3 (the side opposite to the tear tape 15) . Even in such a case, it is possible to reinforce the half-cut 13 portion of the film 3 as compared with the case of the conventional perforation alone. Moreover, the half-cut 13 can be made inconspicuous by positioning it at the corner of the container body 10 as described above. In another embodiment of the present invention shown in FIG. 6 ( c), a plurality of flaws (for example, a depth of 1 to 10 μm) are formed as the half cut 13. 6 (b), which is a reference example, has the scratch 13 on the outer surface side of the film, and FIG. 6 (c), which is another embodiment of the present invention, has the scratch 13 on the inner surface side of the film. The case is illustrated.
[0029]
Further, as another embodiment of the present invention, as shown in FIG. 7C, the breaking means may be a combination of a half cut 13 and a perforation 13a. In FIG. 7A, which is a reference example, in order to facilitate cutting from the upper end or the lower end, the perforations 13 are provided at the upper and lower end portions 5a and 5b of the label body 5, and both the perforations 13a are connected. Thus, a half cut 13 is provided. The length of such perforations 13a, as shown in FIG. 7 (b) is a reference example, the upper end portion 5a is positioned on the shoulder portion side of the container main body 10, the lower end portion 5b is to be positioned on the bottom side of the container main body 10 This prevents the perforation 13a from being caught on a shooter or the like because the perforation 13a is not present on the outer surface of the body portion 10a of the container body 10. Furthermore, it is not necessary to provide the perforation 13a on the straight line of the half cut 13, and as shown in FIG. 7C, which is another embodiment of the present invention , the half cut 13 is provided over the entire length of the label main body 5, A perforation 13 a may be provided in the vicinity of the cut 13. In this case, the half cut 13 and the perforation 13a are set within the width of the tear tape 15.
[0030]
A case where the half cuts 13 are provided on both sides of the virtual line in FIG.
[0031]
Furthermore, the label 1 may be provided on a part of the container body 10, for example, may be provided only on the upper part of the container body 10 so that the phantom line is the lower edge in FIG. Although the said embodiment demonstrated the case where a container main body was a square bottle, the thing of arbitrary shapes, such as a round bottle, may be sufficient as a container main body.
Examples of the container body include glass bottles, metal cans, plastic cups, and paper cups, but they are particularly suitable for PET bottles that require separation of labels during recycling.
Moreover, although the tape 15 is continuously attached to the entire length of the film 3 along the half cut 13, it is not always necessary to provide the entire length of the film 3, and it is possible to intermittently attach a short length.
[0032]
【The invention's effect】
As described above, in the present invention, the breaking means includes a half-cut for breaking formed on the inner surface of the cylindrical label body, and the inner surface of the cylindrical label body covers a portion provided with the half-cut. Thus, since the tape is stuck, the half cut portion can be reinforced. Therefore, even when the container is distributed or when the container is housed in a vending machine, sufficient strength can be obtained in the half-cut portion, and the half-cut may be carelessly broken in the circumferential direction of the label body. Can be prevented.
[0033]
Also, when peeling the cylindrical label body from the container body, the tape is attached to the inner surface of the cylindrical label body. Can break.
[0034]
Moreover, since the half-cut portion is reinforced with the tape as described above, the size of the half-cut is made deeper or shallower depending on the material of the film so that the label body can be easily broken at the time of peeling. Or change the width as desired.
[0035]
Furthermore, when the container body is made of a bottle (PET bottle) molded from a polyester resin, the film is made of a polyester film, and the tape is made of a sheet based on a polyester resin. Can be easily peeled off and removed from the PET bottle, can be used for PET bottle recovery, etc., and even if the label is forgotten to peel off from the PET bottle, Since labels are made of homogeneous materials, there is little support for PET bottle recycling (resin reuse).
