Description

  The present invention relates to a label for opening a shrink package, which can easily cleave the shrink package using the label for opening attached to the joint of the shrink package.

  The shrink-wrapped product is opened by inserting two break induction parts (perforations and cuts) on both sides of the film adhesion part, as represented by PET bottle drinks, and the break induction part from the center of the break induction part. As shown in the bottom of the cup noodles, the method of opening along the same way as the caramel box, packaging the same material as a band like a caramel box at the same time and pulling the material from the band of the material for opening. There is a method in which baking is partially made into a V shape to make it easy to cut and an opening seal is pasted thereon, and the opening of the V shape is widened by peeling off the opening seal. These three types are typical opening methods at present. About these, for example, “Shrink package” in Patent Document 1, “Shrink package and its packaging device” in Patent Document 2, and “Manufacturing method of label for opening and package with label for opening” in Patent Document 3. Some are suggested.

Japanese Patent Laid-Open No. 2003-237741 JP 2003-327271 A JP 2004-315016 A

With the conventional opening methods exemplified in these prior art documents, it is difficult to open 100%. In particular, it is very difficult for elderly people and blind people to find the opening place, and even if it is found, it is difficult to grasp even the protrusion of the opening opening if the hand is not dexterous. Further, according to the experiment of the present inventor, the opening seal attached to the baked portion in the V shape of the cup noodle described above was in a situation where it was not successful even once when the seal was peeled off ten times. In order to prevent these problems and as a reliable means of unsealing, it is natural to drill a hole in a part of the shrink wrap by using a cutter, a sharp-pointed pen or chopsticks as another hand tool, and then open from there. It is done like this. In such a case, if there is no external tool to make a hole nearby, it seems that everyone has experienced the trouble once or twice.
In the current product distribution situation, shrink packaging is an absolutely necessary packaging method from the viewpoint of safety and hygiene, but no perfect solution has been established for opening. The present invention proposed by the applicant of the present invention is formed by pasting a label having a perforation or a cut-inducing portion such as a notch in the center along the connecting portion at the connecting portion of the shrink wrapping, and is composed of an adhesive-free portion at both ends of the label. By grasping the left and right ears with the fingers of the left and right hand and pulling in the opposite direction at the same time, it is possible to tear the label breakage induction part and the shrink film joint at the same time, and as a result, it is easier to open than the joint of the shrink film. It is an epoch-making label. In addition, the conventional opening method has a tendency to make the display and the mouth as small as possible in order not to damage the image of the product. In the present invention, the opening label is used as a POP label together with the idea of reversal, so that anyone can identify the opening and easily open it. The POP label function can also be expected to produce advertising effects.
The POP label is an abbreviation for POINT-OF-PURCHASE label, and the POP label is generally called a pop advertisement label. Product appeal label. Labels that enhance differentiation from other products on the display shelf. A label that pops out of the product. It is said to be a label for increasing display effect.
The present invention is a multi-functional label having the two functions of an opening label of a shrink package and a POP label.

In order to solve the above-mentioned problems, the present invention first attaches an opening label on the shrink film along the joint of the shrink package packaged with the shrink film. A rupture induction part is provided at the center part, provided with adhesive ears on both sides of the rupture induction part and provided with a gripping ear part on both sides, and the rupture induction part of the label for opening is provided. It is made into the structure of the label for opening of a shrink package characterized by sticking along the joint of the shrink package.
Secondly, the outer shape of the label for opening is selectively selected and configured in an arbitrary shape such as a rectangle, a circle, a ribbon, a butterfly, an arrow, etc. An opening label for a shrink wrapping body, characterized in that a description for label operation is written in contrast to the surface of the opening label with a breakage induction portion interposed therebetween. Furthermore, the fourth label is a label for opening a shrink package, characterized in that the description for label operation is printed and displayed in contrast with characters, arrows, designs, and the like. Fifth, the upper surface of the breakage induction portion of the opening label is formed in a V shape, and the valley bottom portion of the V shape is used as the breakage induction starting portion of the breakage induction portion. is there.

By pulling the ear part of the opening label affixed on the shrink film to the both sides with the above configuration, the label breakage induction part and the joint of the shrink film can be cleaved at the same time. It has the effect of providing a functional label with good functionality that can be easily opened.
In this case, when the upper surface of the breakage induction portion of the opening label is formed in a V shape, and the valley bottom portion of the V shape is the breakage induction starting portion of the breakage induction portion, the ear portion of the label is By pulling to both sides or pulling to both sides so as to spread obliquely downward, it is promoted that the joints of the shrink film are more reliably cleaved.
Also, the label for opening is not just a functional label, it has many functions such as presence and advertisement that are excellent in visibility, and pasting shrink-wrapped products until now is impossible by pasting this label Even elderly and disabled people can easily recognize the opening location by visually recognizing it, and it can be opened more easily. In addition, it has the effect of becoming a multi-purpose label that can also obtain the advertising effect of a POP label having excellent advertising properties for manufacturers that sell shrink wrap products.

Hereinafter, the present invention will be described in detail with reference to the drawings relating to the embodiments.
As shown in FIGS. 1, 2, and 3, a label 1 is created based on a seal having an outer size within 60 mm on the left and right sides and a vertical size of 40 mm or less on the top and bottom. The shape may be a rectangular type 1a, or a deformed type such as a ribbon type 1b or a butterfly type 1c. For example, shapes such as a heart shape, a circle shape, an arrow shape, a petal shape, and an animal silhouette shape are conceivable. These are provided by selectively selecting and configuring arbitrary shapes according to customer requirements and market needs, and these shapes can be freely set, and the shapes are not particularly limited. What is important is that the rupture guiding portion 4 constituted by a perforation, a notch or the like is formed so that the label 1 can be broken if the right and left ears 3 and 3 of the label 1 are held in the label center 2 of the label 1 and pulled in the left and right direction. It is to put. By inserting the breakage induction part 4, the label 1 itself is torn first, and then the joint of the shrink film 10 to which the label 1 is stuck is torn. Further, the position where the label 1 is attached to the joint of the shrink film 10 is determined by the break guide portion 4 indicating the position of the label center 2. In addition, the upper surface of the breakage induction portion 4 of the opening label 1 is cut into a V shape, and the valley bottom portion of the V shape is formed as a breakage induction starting portion 4 a of the breakage induction portion 4. When the breakage starting point 4a is formed in this way, the joint of the shrink film 10 can be more reliably connected by pulling the ear portion of the label 1 to both sides or pulling the label 1 to both sides so as to spread obliquely downward. Cleavage is promoted.
As illustrated in FIG. 6, it is preferable to set the ratio of the part with the blade to 2 and the part without the blade to 1 with respect to the blade mold H <b> 2 of the blade unit so that the sewing machine blade can be easily cut. For example, if the blade portion is 2 mm, the bladeless portion is 1 mm, or the blade portion is 1 mm, and the bladeless portion is 0.5 mm, the label 1 is easily torn.
It is necessary to pinch the ears 3 and 3 of 10 mm width or more at the left and right ends of the label 1 with fingers and pull them to both sides. In this case, this operation cannot be performed with a label having an adhesive on the entire back surface of the label 1. It is necessary to make a part without glue in the part (both ears 3 and 3 of the label).

FIG. 2 shows an adhesive surface 5 with glue and non-glue surfaces 6 and 6. There are basically three types of methods for creating the partial glue constituting the adhesive surface 5 and the non-glue surfaces 6 and 6.
First, as shown in FIG. 3, as shown in FIG. 3, a base paper for partial glue is ordered from a base paper manufacturer when placing a base paper order. In this case, if the dimensions of the glued part (adhesive surface 5) at the center of the base paper and the part without glue (ear part 3) on both sides are specified in the order of millimeters, the specified partial base paper can be purchased. . However, an adhesive surface having a width of 5 mm or more is required on both outer sides of the non-glue portion of the ear portion 3. This is also for the purpose of preventing the generation of wrinkles by air entering the non-glue portion during printing. However, this does not solve all the problems. In the case of partial glue printing, the defect rate is nearly doubled compared to the case of printing on a normal full-size glue base paper. In addition, a base paper maker cannot perform partial glue coating on all types of base paper. The types are limited by the facilities of the base paper manufacturer and production convenience. The non-glue part is not accepted unless it is less than half the paper width. There are many restrictions such as having to order a certain amount.
In actual printing, it is important to accurately adjust the position so that the ear portion 3 of the label 1 comes to the non-glue surface 6 and the center of the label 1 comes to the adhesive surface 5.

Next, as a second method, there is a method of performing paste killing. As shown in FIG. 4, purchase a base paper with glue on the entire surface, and once peel off the adhesive-coated upper paper from the release paper (separator) with a rotary type printing machine. This is a method in which silicon varnish is printed on the surface, the adhesive force is killed, and the paper is pasted again with release paper (separator). In this case, the product can be finished in one pass (one stroke).
In front of the first printing unit 1 and the printing unit 2, the upper paper (with adhesive) and the release paper (paper coated with silicon on the surface = separator) are once peeled off. Solid printing is performed partially by the printing unit 1 or 2 on the adhesive surface of the peeled upper paper with a silicon varnish. (The effect of forming a film partially on the surface of the adhesive surface by silicon varnish printing and killing the adhesive force is generated) After printing the silicon, the upper paper and release paper are bonded together. The process up to this point is almost the same when creating a base paper for partial glue. The pasted base paper is printed on the surface with printing units 3 to 7, and the die cutting unit performs half-cutting (processing to cut only the upper paper) with a blade die H2 with a sewing machine blade at the center. When the upper sheet of paper is peeled off (scrap raising), the shrink-open POP label is completed.

Finally, as shown in FIG. 5, as a third method, there is a method of partially leaving a release paper (separator). Slit processing is performed on the release paper side of the boundary between the part requiring glue and the part not requiring glue. Next, insert a finishing blade. Normally, the blade is put into the upper paper (half cut) and finished, but in the case of leaving the separator, the part where the glue is not needed on both sides is inserted into the release paper and partially removed. Perform normal half-cutting on the area where the adhesive surface remains. In the scouring process, the residue including the release paper outside the back slits on both sides is wound up. This completes the label without any part. If the label is peeled off from the release paper remaining in the center with the remaining part of the release paper on both sides, the label will remain on the both side release paper for partial glue substitution. Since the label produced by this method has release paper on both sides, it is most easily grasped when grasping the label for opening. The three methods shown in FIGS. 3, 4, and 5 are the basic partial glue processing methods.
Other special processing methods include partially printing glue (hot-melt coating or glue printing with silk) and a transparent film sandwiched between the upper paper (with adhesive) and release paper and partially glued There is also a method of making a base paper by killing a part of the super-adhesive film where half of the paste is to be killed in advance, raising the other residue, and pasting the adhesive-attached upper paper partly.
However, these other methods are not general because they are special processing.

Briefly explaining the label 1 shown in the present invention, a cut 4 (cut or perforation) as a breakage guide portion enters the label center 2, and the upper surface of the breakage guide portion 4 is formed in a V shape, It can be said that the bottom of the V-shaped form is formed as a breakage induction starting point portion 4a of the breakage induction portion 4, and the ear portions 3 and 3 on both ends are glue paste-free portion labels. It's easy to manufacture, and printing can be done at any printer label manufacturer.
Then, as shown in FIGS. 7 to 11, the label 1 is used as shown in FIGS. 7 to 11, and is drawn and explained on the surface of the label so that it is pulled left and right, or obliquely expanded to the left and right. The remaining space has a POP label function that can effectively promote the product. When entering illustrations and explanations as described above, in contrast to the description of label operation with perforations on the surface of the opening label, as shown in FIG. 7 and FIG. 11, contrast with letters, arrows, designs, etc. The opening label can be printed in multiple colors, and can be printed with explanations and illustrations of the opening method so that it is highly visible and prominent as an advertisement. It is provided as a label for opening a shrink package.
The set is completed by superposing and attaching the breakage induction part 4 and the breakage induction starting part 4a of the seal center 2 to the joint 11 of the shrink film 10 of the shrink-wrapped product with the completed label 1.
The label 1 can be attached by hand (one by hand) or by using a labeling machine to efficiently attach the label 1, but the label 1 of the present invention takes into consideration the current production line. It can handle both.
When tearing the joint of the shrink wrapping, as shown in FIG. 9, the label 1 set on the shrink film 10 is pulled parallel to the tabs 3 and 3 of the label-free label ears with the left and right hands toward the outside. . Alternatively, it is pulled obliquely downward and pulled to the left and right sides. In this case, as shown in FIG. 8, since a floating gap is formed between the ears 3 and 3 and the shrink-wrapped product, the feather-like ears 3 and 3 are pulled outward on the left and right sides. Can be easily done.
Then, as shown in FIG. 10, the label 1 is torn from the perforation 4 after it is torn with the pulling force as the starting point of the breaking induction 4 a of the label center 2. At the same time, the shrink film 10 to which the label 1 is attached is cleaved from the joint 11 and opens.
This is an application of the principle that the adhesive is easily peeled off in the vertical direction but not peeled off in the parallel direction. The joint 11 of the shrink film 10 cannot normally be opened easily. The cause is that the shrink film 10 is contracted by heat and closely adhered to a product such as a beverage container or a tablet container, so that the shrink film 10 itself cannot be directly pinched with a finger. Therefore, the cause is that the force to tear cannot be concentrated on the joint 11. By applying the label 1 of the present invention, the pulling force can be concentrated on the joint 11 of the shrink film 10 and can be easily torn.
In particular, as shown in the embodiment, the upper surface of the breakage induction portion of the opening label is formed in a V shape, and the valley bottom portion of the V shape is used as the breakage induction starting portion 4a of the breakage induction portion. By pulling the ears 3 and 3 of the label to both sides, or pulling the label ears 3 and 3 to both sides so as to spread obliquely downward, it is promoted that the joint (perforation 4) of the shrink film is more reliably broken. There are advantages.

  The strength of the joint 11 itself of the shrink film 10 is not inherently strong, and it can be easily torn even with a little force if it can pinch the edge of the film. The present invention is an epoch-making invention in which the work of pinching both ends of the shrink film 10 is replaced by attaching the label 1 with the ears 3 and 3 so that the shrink film 10 can be easily torn from the joint 11. . Moreover, even visually impaired people and elderly people can easily find the opening by visually recognizing the ears 3 and 3 of the label 1. It is safe because there is no need to use a cutter such as a cutter or scissors. The label material can be made of the same material as the shrink film 10 and becomes a recycled resource. It can also contribute to eco activities. The basic shrink film material is PVC (polyvinyl chloride), PP (polypropylene), PE (polyethylene), PS (polystyrene), PO (polyolefin), PET (polyethylene terephthalate) label 1 material is not limited, but shrink It must be stronger than the film. However, the strength can be reinforced by overlaminating.

Furthermore, the current POP label is merely for promotional purposes and is an unnecessary label that is discarded for consumers. However, it is a multifunctional label that has an advertising effect and an opening function. Become.
Furthermore, it is epoch-making that the manufacture of the label itself is simple and does not require special technology.
Various forms of shrink wrapping can be broadly classified into seven types: L-type three-side seal, pillow-type three-side seal, overlap (caramel wrap), sleeve wrap four-side seal, cap seal, label shrink, and R bag making. Basically, it can only deal with two types of types: three-way seals and pillow-type three-way seals. It has the characteristic that it cannot be opened if there is no joint of shrink wrapping.

  The opening label of the shrink wrapping body of the present invention can be applied to a shrink film for container wrapping having joints. It is also a multi-purpose label that has two functions of an opening label and a POP label. In addition, it is a universal design label that is easy to find and open, and is easy on the weak (children, elderly, and disabled).
