Description

  The present invention relates to a pressure-sensitive adhesive label that can be easily cut at a predetermined position while having a large tensile strength, and a connecting structure for packaging bodies using the same.

  2. Description of the Related Art Conventionally, for the purpose of selling products at a low price, it has been widely practiced to sell a plurality of the same type of goods together. As an example, several sliced hams are wrapped in plastic film packaging material to make a package that can be sold individually. The thing connected with the adhesive label is known.

  And the consumer who purchased this can take out articles | goods individually from each package body, after peeling off an adhesive label and isolate | separating each package body.

  However, according to such a connection structure, the adhesive labels are strongly attached to the article storage part of the adjacent package and the surrounding sealing part, so that each package is inadvertently separated before sale. Although it was possible to prevent this, it was difficult for consumers who purchased the product to peel off the adhesive label to separate each package.

  Therefore, in order for the consumer to easily separate each package, a tape piece or a label (adhesive label) is adhered only to the article storage part of each package, and at the position of the peripheral part (sealing part) of each package. It has been proposed to form a perforation, a V-shaped cut, or an I-shaped cut on an adhesive label (for example, Patent Document 1).

  In addition, the adhesive tape (adhesive label) is provided with an adhesive region and a non-adhesive region, and a perforation, a V-shaped cut, or an I-shaped cut is formed in the non-adhesive region as an easy-to-cut portion. There is also a proposal of positioning at the edge of the peripheral part (sealing part) between each other (for example, Patent Document 2).

Japanese Patent No. 2947349

Japanese Patent No. 3564048

  However, according to the conventional methods disclosed in Patent Documents 1 and 2, since only a part of the adhesive label is adhered to the site of each package, the binding force of each package is weak, and the adhesive label Since a perforation, a V-shaped cut, or an I-shaped cut is formed at a portion that is not adhered to the package, the adhesive label may be accidentally broken at that portion.

For example, perforations, since it is the form of short and small a cut line of several are arranged in a straight line at equal intervals, the acts pull tension on the adhesive label upon transportation or display of the package, the residual between the cut lines Tensile stress concentrates on the slightly connected portion, and the adhesive label breaks at the perforated portion.

  In addition, since the V-cut and I-cut are also cut inward from one edge of the label, the label is inadvertently broken at the cut and each package is separated before sale. There was a risk of it.

  The present invention has been made in view of the circumstances as described above, and an object thereof is to provide an adhesive label that can be easily cut as necessary while having a large tensile strength. It is to make it the connection structure of the packaging body which uses such an adhesive label, and to perform the isolation | separation operation | work of each packaging body easily.

  In order to achieve the above object, the present invention provides an adhesive label in which the surface of a label body having a pressure-sensitive adhesive layer formed on the back surface is covered with a protective film, and a plurality of short cut lines engraved on the label body and the protective film. Each of the short cut lines of the label main body is arranged along the edge of the label main body, and each is inclined or perpendicular to the arrangement direction. Each of the short cut lines of the protective film is arranged along the edge of the protective film in a state of intersecting with each of the short cut lines of the label main body one by one, It is formed in the direction orthogonal to each other.

  Moreover, in the adhesive label which coat | covered the surface of the label main body by which an adhesive layer is formed in the back surface with a protective film, the multiple short cut line engraved on the label main body, and the multiple short cut line engraved on the protective film, Each short cut line of the label main body is formed along the edge of the label main body, and each is formed in a direction inclined or orthogonal to the alignment direction, and the protection Each short cut line of the film is formed along the edge of the protective film between the respective short cut lines of the label body, and each is formed in a direction inclined or orthogonal to the arrangement direction. To do.

On the other hand , a plurality of packaging bodies each having an article storage portion storing articles and a bowl-shaped sealing portion surrounding the article storage portion are arranged so as to partially overlap each other, and the respective packaging bodies are arranged on the front and back sides. In a packaging structure connected by coupling means attached on both sides, at least one of the coupling means on the front and back sides is composed of an adhesive label configured as described above, and the package assembly in which the cut-out aggregate region in the adhesive label is adjacent It is characterized by straddling the boundary part.

  The pressure-sensitive adhesive label according to the present invention has a laminated structure of a label main body and a protective film, and both of them are individually engraved with a plurality of short cut lines arranged along their edges, and the short cut lines are aligned with the alignment direction. In this case, the short cut lines of the protective film are crossed one by one with respect to the short cut lines of the label main body, or provided between the short cut lines of the label main body. The label main body and the protective film complement each other with respect to the decrease in yield strength against the tensile force of the edge along the direction in which the short cut lines are arranged.

  For this reason, the adhesive label does not inadvertently break in the cut gathering area composed of the short cut lines of the label main body and the protective film, and the intended working force can be given to the cut gathering area for the purpose of label cutting. For example, the label main body can be cut along the protective film while cutting the protective film starting from one of the short cut lines formed along the edge of the protective film.

On the other hand , according to the connected structure of the package connected by the adhesive label as described above, the cut aggregate region in the adhesive label straddles the boundary portion of the adjacent packages, so that each package is required as necessary. Each package can be maintained in a connected state when the package is transported from the manufacturer to the customer.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing a configuration example of a connecting structure for packaging bodies using an adhesive label according to the present invention, FIG. 2 is a side view of the connecting structure, and FIG. 3 is a bottom view of the connecting structure. . In these drawings, 1A, 1B, and 1C are package bodies (in this example, triple), and each of the package bodies 1A to 1C is an article 11 made of two plastic films having thermoplastic properties such as polyethylene and polypropylene. It is sandwiched and heat sealed around it.

  In this example, the article 11 is a plurality of sliced hams, and the article storage section 12 storing the sliced ham has a circular shape, and the surface side is raised by the thickness of the article 11. On the other hand, 13 is a sealing part formed by heat-sealing two upper and lower plastic films while leaving the article storage part 12, and this sealing part 13 has a square bowl shape surrounding the article storage part 12, and the article storage part It works to maintain 12 airtightness. One corner of the sealing portion 13 is a non-welded opening portion 14, and the upper and lower plastic films are peeled off from the opening portion 14 so that the article 11 in the article storage portion 12 can be taken out.

  And each packaging body 1A-1C comprised as mentioned above is arranged in a row so that it may overlap partially, and the adhesive labels 2 and 3 are stuck as a coupling means on those both sides, and it connects integrally It is a structure.

  In this example, the pressure-sensitive adhesive labels 2 and 3 are in the form of strips. Among these, the front-side pressure-sensitive adhesive label 2 has a product name, sales price, etc., and the back-side pressure-sensitive adhesive label 3 contains the raw material or manufacturer of the article 11. It is written. The adhesive labels 2 and 3 may be oval or other shapes.

  Here, the adhesive labels 2 and 3 are adhered to the article storage portion 12 and the sealing portion 13 of the adjacent packaging bodies 1A, 1B and 1B, 1C, and both ends thereof are the packaging bodies 1A, 1A, It is adhered to the 1C article storage unit 12. In particular, in this example, the front-side adhesive label 2 has a region along the long-side end edges as a band-shaped cut gathering region 21 used to cut the adhesive label in the transverse direction over the entire length. The cut gathering region 21 extends in the connecting direction of the respective packaging bodies 1A to 1C across the boundary portions of the adjacent packaging bodies 1A, 1B and 1B, 1C.

  FIG. 4 is a plan view showing the pressure-sensitive adhesive label, and FIG. 5 shows a partially enlarged cross section taken along line XX of FIG.

  As is apparent from FIG. 5, the pressure-sensitive adhesive label 2 is a thin laminated structure having a label main body 22 as a base and a protective film 23 covering the entire surface of the label main body. Among these, the label main body 22 is a regular paper piece (printing paper) punched out from the base paper, and an adhesive layer 24 is formed on the back surface thereof by applying an adhesive, and printing is performed on the opposite surface. . On the other hand, the protective film 23 is a thin piece made of a synthetic resin having the same shape as the label main body 22, and is superposed on the surface of the label main body 22 and heat sealed, or the surface of the label main body 22 using an adhesive. Glued to. Note that a release paper (release liner) (not shown) is attached to the adhesive layer 24 before use.

  FIG. 6 is a plan view showing the label main body and the protective film separately. As apparent from these drawings, a plurality of parallel short cut lines 21A are engraved on the label main body 22 at regular intervals along two opposite edges 22A and 22A on the long side. In this example, each short cut line 21A of the label main body 22 is an oblique cut formed in a direction inclined with respect to the arrangement direction (the length direction of the end edge 22A), and each one end of the label main body 22 has a label main body. It is closed without passing through the edge 22A.

  On the other hand, a plurality of parallel short cut lines 21B are also engraved on the protective film 23 at regular intervals along two opposite long side edges 23A and 23A. The short cut line 21B is also formed in a direction inclined with respect to the arrangement direction (the length direction of the end edge 23A), and one end thereof is closed without being connected to the end edge 23A of the protective film 23. The incline direction of the cut line 21B is opposite to that of the short cut line 21A of the label main body.

  Each short cut line 21B of the protective film 23 is on the surface of the label main body 22 and intersects each short cut line 21A one by one (indicated by x in FIG. 4). 21A and 21B are connected in the same direction to form the cut gathering region 21 described above.

  Here, the effect | action of the adhesive label 2 comprised as mentioned above is demonstrated. According to the pressure-sensitive adhesive label 2, the strength of the edge 22 </ b> A is reduced due to the presence of the short cut line 21 </ b> A with respect to the tensile force in the length direction of the cut gathering region 21, and the protective film 23 has a short cut line. The presence of 21B reduces the proof stress of the edge 23A.

  However, the decrease in yield strength of the end edge 22A of the label main body 22 is supplemented by the protective film 23 superimposed thereon, and the decrease in yield strength of the end edge 23A of the protective film 23 is supplemented by the label main body 22 existing therebelow.

  Therefore, the pressure-sensitive adhesive label 2 has a higher tensile strength than the conventional product provided with perforations, V-shaped cuts, and I-shaped cuts, but is locally required in the cut gathering region as shown in FIG. When the tensile force is applied, the protective film 23 is broken at the position a between the one end of the short cut line 21B (shown by a solid line) and the end edge 23A at the position where the tensile force is concentrated, and the label is adjacent to the protective film 23. The main body 22 is broken at a portion b between one end of the short cut line 21A (shown by a broken line) and the end edge 22A.

  Thus, as shown in FIG. 8, the protective film 23 is torn from the position of the short cut line 21B, and the label body 22 is also torn from the position of the short cut line 21A. The adhesive label 2 can be cut without any trouble, and since the package connected by this extends over the boundary portion between adjacent ones (see FIG. 1), the individual packages are separated. Work can be done easily. FIG. 9 shows an enlarged cut portion of the adhesive label 2.

  Next, if the manufacturing method of the above adhesive labels 2 is demonstrated easily, first, it will print on the base paper which comprises the label main body 22, and will apply an adhesive to the back surface, and will affix a release sheet. Next, a short cut line is cut in each area of the base paper, and a plastic film sheet formed with the protective film 23 is overlaid on the surface, and this is heat-sealed or bonded using an adhesive.

  After that, the plastic film sheet and the printed base paper are simultaneously punched out using the same punching die, and at the same time, the blade is inserted into the plastic film sheet by the thickness of the plastic film sheet at the position of the short cut line engraved on the base paper. By cutting the short cut line, the adhesive label 2 as in the above example is obtained.

  The configuration example of the present invention has been described above. However, the adhesive label 2 is not limited to the configuration described above. For example, as illustrated in FIGS. When connecting the individual package bodies, the cut aggregate regions 21 may straddle border portions of adjacent package bodies. The adhesive label 2 shown in FIG. 10 is used to connect two packages, and the adhesive label 2 shown in FIG. 11 is used to connect three packages. The adhesive label shown in FIG. 2 is used to connect four packages.

  Further, the short cut lines 21A and 21B forming the cut collecting area 21 are not limited to be inclined, and for example, as shown in FIG. 13, a short cut line 21A (indicated by a broken line) of the label main body 22 is an edge 22A. In contrast, the short cut line 21B (shown by a solid line) of the protective film 23 is formed so as to intersect the short cut line 21A of the label body so as to be orthogonal to the edge 23A. Also good.

  Furthermore, as shown in FIG. 14, the short cut lines 21A and 21B are formed in a state orthogonal to the end edges 22A and 23A, respectively, while the short cut lines 21A and 21B do not cross each other. The short cut lines 21B may be formed between the short cut lines 21A of the label main body 22 so that the short cut lines 21A and 21B appear alternately in the arrangement direction. In FIG. 14, the short cut lines 21A and 21B may be inclined with respect to the end edges 22A and 23A.

Here, in the illustrated example, the short cut lines 21A and 21B are closed, and minute cuts are provided between the end edges 22A and 23A. However, the short cut lines 21A and 21B are open and the edges 22A, 21B are open. You may make it open to 23A. However, in order to increase the tensile strength of the pressure-sensitive adhesive label 2, as shown in the example described above, a plurality of parallel short cut lines 21 </ b> A engraved along the edge 22 </ b> A of the label main body 22 are inclined with respect to the arrangement direction. It is most preferable that the short cut line 21B of the protective film 23 is inclined in the direction opposite to the short cut line 21A of the label main body while crossing each other one by one.

  On the other hand, the adhesive label 2 as described above may be affixed to the back side of each package instead of the adhesive label 3, or may be affixed to both front and back sides of each package. In addition to its use as a package, it can also be used as sealing paper.

  On the other hand, each packaged body that is a connected structure is not limited to a package that contains processed food such as sliced ham as a vacuum pack. For example, a package that stores toys and other items between a mount and a transparent plastic package. But you can.
