Japanese Utility Model Publication No. 4-3963 Japanese Patent Laid-Open No. 10-175641 JP 2005-87331 A

  When the bag (article storage unit) is formed using a right triangle-shaped bag-forming piece in the bag-forming seal (small article holder) having the above-described configuration, the inserted small article (plate-shaped accessory) is likely to drop off. It was found (see Patent Document 1 Fig. 4).

  The right-angled triangular bag-forming piece is only intended to be attached along the corner (corner) of the packaging container. The same applies to Patent Documents 2 and 3.

  In addition, since the right-angled triangular bag-forming pieces can be manufactured as a pair at the same time, the productivity is good (see, for example, FIG. 1 of Patent Document 1).

  Further, in Patent Document 2, there is a proposal for improving the retention of plate-shaped small objects by installing an embossed protrusion projecting on the product side serving as the back surface at a position near the corner of the right triangle shape of the bag. (See claim 5).

  In view of the above, it is a first object of the present invention to provide a bag-forming seal excellent in retention of small bag-like articles formed when a right-angled triangular bag-forming piece is used. .

  Another object of the present invention is to provide a bag forming seal that is excellent in the insertion property of the plate-like small articles formed when the bag forming piece is used.

  Still another object of the present invention is to provide a bag forming seal having a shape structure that can be manufactured with good productivity in each of the bag forming seals.

  The present inventors have found that the above first object can be achieved by using a bag-forming seal comprising the following invention specific matters.

That is, one of the present invention includes a release layer (peeling layer), an adhesive layer (adhesive layer), and a main body layer, and includes a right triangle bag forming portion and a periphery excluding the hypotenuse of the right triangle of the bag forming portion. In the bag forming seal provided with one or a plurality of bag forming pieces composed of the adhesive margin portion formed in the adhesive margin portion, the release layer can be peeled only at the adhesive margin portion,
On one side or both sides sandwiching the right angle of the right triangle of the bag forming portion, the article holding auxiliary portion is formed by partially protruding the glue margin portion to one side or a plurality of locations on the bag forming portion side. Features.

  By setting it as the said structure, the holding | maintenance property of the plate-shaped accessory of the bag formed at the time of use of the right triangle triangular bag formation piece improves. That is, the bag-forming piece peeled off from the bag-forming seal is attached to the flat surface of the packaging container through the glued portion to form a right-angled triangular bag. It will not fall off even if tilted. This is because there is an article holding auxiliary portion that partially protrudes from the gluing portion into the bag on the side of the bag forming portion sandwiching the right angle of the right triangle (see FIG. 2).

  The article holding auxiliary portion may be provided at one location, but may be formed at two locations on the side of the bag bottom when using the right angle of the right triangle, ie, the base portion side and the tip portion side. Since the article holding assist function is carried out at two places, either one of them has the article assisting function even if the insertion position of the plate-shaped accessory with respect to the bag is slightly shifted. For this reason, dropping off of the plate-shaped accessory from the bag is prevented.

  In each of the above-mentioned configurations, a folding brazing line can be attached from the front side of the main body layer along the inside of the oblique side of the right triangle of the bag forming portion. When the bag is formed on the outer flat portion of the packaging container in the same manner as described above, the gap between the openings formed by the hypotenuses of the right triangle of the bag is widened to the outside, and the insertion insertion property of the plate-like accessory is improved. The objective can be achieved.

  In the above configuration, a quadrangular laminate composed of a release layer, an adhesive layer, and a main body layer, and a quadrangular back side engraved line is formed by cutting only the release layer from the back side of the quadrangular laminate, A square front-side engraved line cut only in the main body layer and the adhesive layer is formed outside the back-side engraved line, and further, a piece dividing line that cuts through the square of the front-side engraved line in a plane oblique direction is formed. Thus, a pair of the bag forming pieces can be provided, and the piece dividing line can be configured as a diagonal line of a flattened quadrangle formed by extending one opposite side of the quadrangle of the back side engraving line. By adopting such a configuration, it is possible to form the article holding auxiliary part on the front end side without forming the inner protrusion on the square blade of the back side engraving line, and it is possible to manufacture with good productivity, and the third object is achieved. it can.

  In each of the above configurations, the outer side of the front side engraving line is a holding frame formed only by a release layer, and the front side engraving line and the back side engraving line at both ends of the piece breaking line It can be set as the structure by which the release layer in the middle is left uncut. By setting it as the said structure, a surplus part can be collectively recycled as industrial waste. Moreover, there is no possibility that the bag-forming seal is wound on the surplus portion, and as a result, productivity is improved.

  In each of the above configurations, any of the main body layer, the adhesive layer, and the release layer can be formed of a transparent material. It is possible to improve information transferability when holding small plate-like items that are information media such as greeting cards and business cards. Furthermore, when the packaging container is formed of a transparent material, the internal visibility of the packaging container is improved.

(3) and (4) are a plan view and a cross-sectional view, respectively, in the front-side engraved line forming step and the broken line adding step. It is a top view which shows the bag formation seal of other one Embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described.

  As shown in FIG. 1, a release layer (peeling layer) a, an adhesive layer (adhesive layer) b, and a main body layer c, and a right triangle bag forming portion 17 and a hypotenuse of the right triangle of the bag forming portion 17 are formed. One or a plurality of bag forming pieces 20 including the margin allowance 19 formed around the periphery are provided, and the release layer a can be peeled only from the margin allowance 19.

  Here, the release layer a is a release paper (release plastic sheet) that has been subjected to a release treatment, the adhesive layer b is usually a pressure-sensitive adhesive, and the main body layer c is formed of a plastic or paper sheet. The plastic is not limited to either transparent or non-transparent. For example, when forming with a transparent material, polyester, polyethylene, polypropylene, polyvinyl chloride (PVC), etc. can be used.

  The thickness of each layer is not particularly limited and varies depending on the selected material. For example, the main body layer c and the release layer a are appropriately selected from the range of 20 to 500 μm, desirably 30 to 100 μm, and the adhesive layer b is 10 to 50 μm. Select appropriately from the range.

  Here, the right triangle of the bag forming portion 17 has two sides sandwiching a right angle as shown in the figure, and one side is a long side that is the bag forming portion bottom side 17a and the other side is a short side that is an upright side. The relationship between the long side and the short side may be reversed, and the right triangle may be an isosceles triangle. In addition, although the length ratio of a long side and a short side changes with design properties and the kind of the plate-shaped accessory G to hold | maintain, it selects suitably from the range of long side / short side = 1 / 1-2 / 1. Usually, it is desirable that the ratio of long side / short side≈golden ratio (1.618) from the viewpoints of design properties and retention of small plate-like objects.

  The bag-forming seal S of the present embodiment is a quadrangular laminate composed of a release layer a, an adhesive layer b and a main body layer c, and is a quadrangular laminate in which only the release layer a is cut from the back side of the quadrangular laminate. A back side engraving line C1 is formed, and a rectangular front side engraving line C3 in which only the main body layer c and the adhesive layer b are cut is formed outside the back side engraving line C1. A piece dividing line C2 for dividing and cutting a quadrangle in a plane oblique direction is formed, and a pair of bag forming pieces 20 are provided. In the present embodiment, the bag forming piece 20 has a holding frame made of only the release layer a by removing unnecessary portions (main body layer c and adhesive layer b) 27a on the outside of the square of the front side engraving line C3. 27.

  Here, the size of the rectangle of the back side engraving line C1, the rectangle of the front side engraving line C3, and the holding frame 27 is not particularly limited.

  For example, when the square of the back side engraving line C1 is 110 × 65 mm, the size of the front side engraving line C3 is a pair of glue margins formed between the back side engraving line C1 and the front side engraving line C3. The width of the square ring corresponding to 19 and 19 is set to be 5 to 10 mm. In the example shown in the figure, the widths are the same, but the vertical and horizontal directions may be different. For example, the width of the bag forming portion 17 on the side that is the upright side of the bag (easily peeled off from the bottom side) is increased.

  The size of the square laminate formed of the laminate raw fabric 31 is such that the protruding width of the holding frame 27 is 5 to 10 mm in the longitudinal direction and 1 to 2 mm in the lateral direction. The reason why the width in the short direction is reduced is to reduce the loss as much as possible when taking the material of the bag forming seal S with the direction along the feeding direction of the laminated raw fabric 31 of the bag forming seal S as the short direction. It is.

  Then, on the long side of the bag forming portion 17 that sandwiches the right angle of the right triangle, the margin part 19 is partially projected toward the bag forming portion 17 at the base portion side (right side vicinity) and the tip portion side. Thus, first and second article holding auxiliary portions 29 and 30 are formed. Here, the shape of the partial protrusion of the first article holding auxiliary portion 29 on the base side is a semicircular shape, but may be a trapezoidal shape or a triangular shape. The protrusion length (semicircle radius) in the case of the semicircular shape is 3 to 6 mm when the bag forming seal S has the above-mentioned dimensional specifications.

  Further, the second article holding auxiliary portion 30 on the front end side is formed such that the piece dividing line C2 is a diagonal line of a flattened rectangle T configured by extending one side of the rectangle of the back side engraved line C1. Has been. When this configuration is adopted, the article holding auxiliary portion 30 on the tip end side can be formed without forming the inner protruding portion 35a on the deformed rectangular blade 35 forming the back side engraving line C1 (FIGS. 1 and 4-B). 3)).

  And it is desirable that the holding frame 27 has a three-layer structure of the main body layer c, the adhesive layer b, and the release layer a from the standpoint of form retention (handleability) of the bag forming seal S, but in this embodiment, the bag The upper side of the projecting portion of the holding frame 27 is peeled off and formed only by the release layer a for inspection of defective formation in the manufacturing method described later of the formation piece 20. Further, the holding frame 27 can be configured as a holding side (connected side) only at the top and bottom, or a single-piece configuration in which only a bag forming piece without a holding frame is used. When the holding frame 27 is formed only by the release layer a, as shown in FIG. 1 (B), there is an uncut portion between the front side engraving line C3 and the back side engraving line C1 at both ends of the piece dividing line C2. It is desirable to have the configuration described above. For the above reasons.

  Next, the usage aspect of the said bag formation seal | sticker S is demonstrated (refer especially FIG. 2).

  The holding frame 27 of the bag forming seal S is grasped with a finger, and the bag forming piece 20 is peeled off from the bag forming seal S. Then, the release layer a of the adhesive margin 19 is peeled off, and the adhesive layer b of the adhesive margin 19 of the bag forming piece 20 is exposed. The bag forming piece 20 in this state is adhered by pressing the adhesive layer b of the adhesive margin portion 19 against the outer flat surface portion (corner portion) of the packaging container P. Then, a right-angled triangular bag B is formed at the corner of the packaging container P. Since the bag B is a right triangle, it can be inserted and inserted even if the plate-shaped accessory is longer than the length of the bottom (long side) of the right triangle. That is, it has flexibility with respect to the size of the plate-like accessory (for example, a postcard and a postcard containing a postcard), and it is not necessary to prepare a bag forming seal of another size.

  In addition, when the small plate-like object is inserted into the bag (pocket) B in which the packaging container P is formed, since the opening O side is opened outward as shown in the figure, the small plate-like object G can be inserted smoothly. And even if the packaging container P is inclined, the inserted small plate G does not fall out of the bag. This is because the adhesive layer b is exposed on the base part and the tip part side of the bottom side and the article holding auxiliary part 29 exists (see FIG. 2A). The adhesive layer b is a pressure-sensitive adhesive layer and hardly contaminates the small plate-like objects.

  Here, as described in Patent Documents 2 and 3, the bag-forming seal of the present invention is a holding container (pocket) such as a thank-you card or a business card on a packaging container such as a gorgeous article, a crude article for entertainment, or a film package product thereof. It can also be used to form various types of paper and plastic document files, as well as holding bags for storing notes such as notebooks, and bags for inserting delivery cards for product containers in factories. Is.

  Next, an example of a method for producing the bag forming seal will be described.

  A layered raw fabric (made of ready-made products) 31 composed of a release layer a, an adhesive layer b, and a main body layer c is fed out from a feed roll (not shown) and fed forward, and the following (1) forming a back side engraved line ( (Half-cutting) step, (2) piece cut line forming step, (3) front side engraved line forming (half-cutting) step, (4) bent brazing line adding step, (5) unnecessary portion removing step, and (6) It is manufactured through a cutting process (see FIG. 3).

(1) Back side engraved line forming process:
This is a step of forming the back side engraved line C1. By pressing the laminated original fabric 31 with the upper pressing die 39 against the back side engraving die 37 provided with the deformed quadrangular blade 35 provided with the partially semicircular inner protrusion 35a at the rotationally symmetric position twice. Only the release layer a is cut so as to leave the main body layer c and the adhesive layer b (FIG. 4A (1)).

(2) Piece break line forming step:
This is a step of forming a piece breaking line C2. While supporting the laminated original fabric 31 with the first lower receiving die 41, the dividing cutting die 45 provided with the oblique cutting blade 43 is lowered to cut through the three layers of the main body layer c, the adhesive layer b and the release layer a. ( FIG. 4A (2) ).

  Here, as in the embodiment, when the piece dividing line C2 does not cut the release layer a between the back side engraving line C1 and the front side engraving line C3, within the square of the back side engraving line C1 A spacer 44 having a thickness substantially equal to the thickness of the release layer a is disposed along the oblique cutting blade 43.

(3) Front side carving process:
This is a step of forming the front side engraved line C3. While supporting the laminated original fabric 31 with the second lower receiving die 47, the front side engraving die 51 having the quadrangular blade 49 is lowered so that the main body layer c and the adhesive layer b leave the release layer a. Cut (FIG. 4B (3)).

(4) Folding brazing line addition process:
This is a step of additionally forming a bent brazing line L. While supporting the laminated original fabric 31 with the third lower receiving die 53, the brazing blade die 57 having a pair of brazing blades 55 is lowered to add a pair of folding brazing lines L, L ( FIG. 4B ( 4) ).

  In addition, although the said division | segmentation cutting | disconnection type | mold 45, the front side engraving type | mold 51, and the brazing blade type | mold 57 are separated and displayed in the example of a figure, it is good also as an integral continuous type | mold. Three processes can be performed simultaneously with one mold lowering. In this case, it is desirable that the length of the brazing blade mold 57 be 3/5 to 4/5 (and further around 2/3) of the diagonal length of the back side engraved line C1. Since the brazing blade mold 57 is lowered simultaneously with the cutting and engraving dies 45 and 51, the drag received by the brazing blade mold 57 is reduced, and the processing stability of each mold is hardly hindered.

  Further, the arrangement order of the engraving dies 37, 51 to the cut-and-cut dies 45 and the brazing dies 57 is desirable as described above, but can be replaced.

(5) Unnecessary part removal step:
This is a step of removing the front side unnecessary portion 27a by winding it with a winding roll 59 while leaving the release layer a of the holding frame 27. The main body layer c above the release layer a on the outer side of the front side engraving line C3 of the holding frame 27 is peeled off together with the adhesive layer b so that the holding frame 27 is made only of the release layer a. This unnecessary portion removing step can also serve as an inspection for defective engraving of the bag forming seal S.

(6) Cutting process The rectangular bag forming seal S is continuously manufactured by cutting with the cutting machine 60 between the pair of bag forming pieces 20 formed in parallel with the laminated raw fabric.

  In addition, the bag formation seal | sticker of this invention is not restricted to the said embodiment, It extends to various aspects within the range described in each claim.

  For example, FIG. 5 shows that the piece dividing line C2 is formed along the diagonal line of the back side engraving line C1 in the above embodiment. Therefore, the second article holding auxiliary portion 30 on the front end side is formed by projecting the margin part 19 in a semicircular shape in the vicinity of both end portions of the square diagonal position of the back side engraving line C1.

  Others are the same as those of the above-described embodiment, and thus the same reference numerals are given and description thereof is omitted.

  Further, as described above, the manufacturing method of the bag-forming seal is not limited to the method of drawing out the roll-shaped laminated raw material and engraving it, and the adhesive layer and the main body layer are formed on the sheet-shaped release paper (release layer). Of course, it can also be manufactured by sequentially forming them and engraving them with an engraving die while shifting them.
