Description

  The present invention relates to a wrapping paper and a packaging product for packaging a plurality of beverage cans together.

  Various types of wrapping paper are known for packaging a plurality of beverage cans containing alcoholic beverages such as beer or soft drinks. Japanese Patent Laying-Open No. 2015-123984 describes a multipack packaging box that collectively packages six beverage cans in which three beverage cans arranged in series are arranged in two rows. This multi-pack packaging box is wrapped around a plurality of beverage cans from above, below, left and right by being folded along a plurality of folding lines.

  This multi-pack packaging box has a holding flap portion (gusset portion) that prevents the beverage can from popping out or dropping out from an opening portion that opens back and forth. The holding flap portion is a push-in flap piece (bending portion) that is folded inside the opening to hold the beverage beverage inside, and a retaining strip piece (connecting portion) that extends obliquely from the push-up flap piece toward the upper surface portion. It is constituted by.

Japanese Patent Laying-Open No. 2015-123984

  Since the wrapping paper such as the multipack packaging box described above is provided with a gusset portion that prevents the beverage can from falling off, it is possible to prevent the beverage can from coming out of the opening. However, for example, when a packaged product wrapped with the aforementioned wrapping paper falls and receives an impact, the gusset portion may break.

  Further, the gusset portion is configured by a bent portion that is folded inward and a connecting portion that extends obliquely from the bent portion toward the upper surface portion, and breaks into the gusset portion due to the strength of the connection strength between the bent portion and the connecting portion. Is likely to occur. Specifically, when the connection strength between the bent portion and the connecting portion is too strong, the rupture portion is likely to break between the bent portion and the side surface portion when dropped, and the connection strength between the bent portion and the connecting portion is too weak. In such a case, breakage tends to occur at the connecting portion or at the boundary portion between the connecting portion and the bent portion when dropped. Thus, the wrapping paper described above has room for improvement in terms of strength against dropping.

  Therefore, an object of the present invention is to provide a wrapping paper and a wrapping product with increased strength against dropping.

  The wrapping paper according to the present invention is a wrapping paper that surrounds and wraps a beverage can, and the beverage can is packaged in an upper surface portion that is located above the beverage can, and the beverage can is packaged in the beverage can side. A pair of side portions located on the side, a lower surface portion located below the beverage can in a state where the beverage can is packaged, and a gusset portion that is bent inward at an end portion of the side portion. And a connecting portion that is located outside the bending portion and connects the bending portion and the upper surface portion, and a linear first perforation is formed at the boundary between the bending portion and the connecting portion. A straight second perforation is formed at the boundary between the bent portion and the side surface, and the first perforation is formed at the straight first slit and both ends of the first slit. A first linear connecting portion located and connecting the bent portion and the connecting portion; Thus is formed, the length of each first connecting portion is and less than 7.0mm or 5.0 mm.

  According to the wrapping paper of the present invention, the connecting portion and the bent portion are continuous via the first perforation and are connected by the two first connecting portions of the first perforation. And the connection strength of a connection part and a bending part can be made favorable by making each length of two 1st connection parts more than 5.0 mm and less than 7.0 mm, and the packaging product fell. Sometimes, the connecting part and the bent part can be made difficult to break. Therefore, the strength of the gusset part against dropping can be increased.

  The width of the connecting portion at the end on the lower surface portion side of the first slit is longer than the length of each first connecting portion, and the connecting portion at the end portion on the upper surface portion side in the first connecting portion on the upper surface portion side. It may be shorter than the width. In this case, the width of the connecting portion can be made narrower from the upper surface side toward the lower surface side, and the width of the connecting portion at the end portion on the lower surface side of the first slit is made longer than the length of each first connecting portion. Yes. Therefore, the width of the connecting portion can be widened to make it difficult to concentrate the impact force on the connecting portion, and the breakage of the connecting portion can be further reliably suppressed.

  The second perforation is formed by alternately arranging the second slits and the second connecting portions in a straight line, and the total length of the first connecting portions is set to A (mm), second When the total value of the lengths of the joint portions is B (mm) (A and B are positive real numbers), 0.435 ≦ (A / B) ≦ 0.650 may be satisfied. By combining the total length of the first connecting portion connecting the connecting portion and the bent portion and the total length of the second connecting portion connecting the bent portion and the side surface portion with the aforementioned relationship, the strength of the connecting portion and The balance with the strength of the bent portion can be improved. Therefore, the connecting portion and the bent portion can be made more difficult to break, and the strength against dropping can be further increased.

  A packaged product according to the present invention includes the wrapping paper described above and a beverage can packaged with the wrapping paper. Thus, since the packaging product which concerns on this invention is equipped with the wrapping paper mentioned above, it can be set as the packaging product with which the intensity | strength of the gusset part with respect to fall was raised.

  According to the present invention, it is possible to provide a wrapping paper and a wrapping product with increased strength against dropping.

It is a perspective view which shows the gusset part periphery of the wrapping paper of FIG. It is the figure which expanded the gusset part in the expanded view of FIG. (A), (b) and (c) is a figure for demonstrating the drop experiment with respect to a wrapping paper and a packaging product. FIG. 6 is a chart showing specifications of examples and comparative examples used in the drop experiment of FIG. 5. 6 is a chart showing the results of the drop experiment of FIG. 5 for each example and comparative example.

  Hereinafter, embodiments of a wrapping paper and a wrapping product will be described in detail with reference to the drawings. In the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 1, the wrapping paper 1 of the present embodiment is, for example, a six-can pack that packages six 500 ml beverage cans C together. The packaged product 100 includes a wrapping paper 1 and a beverage can C packaged with the wrapping paper 1. The wrapping paper 1 is positioned below the beverage can C, with the upper surface portion 2 positioned above the beverage can C, the pair of side surface portions 3 positioned on the sides of the beverage can C, in a state where the beverage can C is packaged. The lower surface part 4 to be provided. The wrapping paper 1 surrounds and holds six beverage cans C from the top, bottom, left, and right.

  In the following, for convenience, the direction in which the upper surface portion 2 and the lower surface portion 4 are located when viewed from the packaged beverage can C is defined as the vertical direction, the direction in which the pair of side surface portions 3 is disposed is defined as the horizontal direction, and the vertical direction and the left and right directions. The direction orthogonal to the direction will be described as the front-rear direction. However, these directions are merely for convenience of explanation and do not limit the scope of the present invention.

  As shown in FIG. 2, the wrapping paper 1 has a substantially rectangular shape in the unfolded state. In the developed wrapping paper 1, a pair of separated lower surface portions 4 are positioned at both ends, the side surface portion 3 is positioned at the center side of the lower surface portion 4, and one upper surface portion is positioned at the center side of the side surface portion 3. 2 is located. That is, in the developed wrapping paper 1, the separated lower surface portion 4, the one side surface portion 3, the upper surface portion 2, the other side surface portion 3, and the separated other lower surface portion 4 are arranged in this order. It is installed. In the unfolded state of the wrapping paper 1, the lower surface portion 4 and the side surface portion 3 are continuous via a fold line 5 that extends in a direction orthogonal to the parallel arrangement direction of the lower surface portion 4 and the side surface portion 3. Moreover, the side part 3 and the upper surface part 2 are continuing via the bending line 6 extended in the direction orthogonal to the said parallel arrangement direction.

  Moreover, as FIG.1 and FIG.2 shows, the wrapping paper 1 has a pair of opening part 1a open | released in the front-back direction in the state which packaged the beverage can C. The wrapping paper 1 includes a gusset portion 10 that protrudes from each side surface portion 3 to the opening 1 a and extends obliquely toward the upper surface portion 2. Each gusset portion 10 holds the beverage can C so that the beverage can C does not fall out of the opening 1a by protruding inward of the opening 1a above each side surface portion 3.

  The upper surface portion 2 has a pair of gripping portions 2a, and each gripping portion 2a includes a U-shaped cutout portion 2b and a bent portion 2c that connects one end and the other end of the cutout portion 2b. . The grip portion 2a can lift the packaged product 100 by putting a finger under the bent portion 2c by cutting the cut portion 2b and folding the cut portion 2b inside the wrapping paper 1. .

  The upper surface portion 2 includes a pair of cutout portions 2f extending from one end 2d toward the other end 2e. Each of the cutout portions 2f extends obliquely by a predetermined length so as to go to the side surface portion 3 as it goes away from the other end 2e, and an oblique side portion 2g that extends obliquely by a predetermined length so as to go to the side surface portion 3 as it goes away from one end 2d. It includes a hypotenuse part 2h and a straight line part 2j that connects the hypotenuse parts 2g and 2h and extends parallel to the folding line 6. In addition, since a notch recessed in a V shape is formed at one end 2d of the cutout portion 2f, the cutout portion 2f is easily cut out with a finger starting from these cutouts.

  The side surface portion 3 has three holes 3a, 3b, 3c at the boundary with the upper surface portion 2, and the holes 3a, 3b, 3c are arranged along the folding line 6 in this order. . The hole 3 a and the hole 3 c are disposed at both ends of the folding line 6. The hole 3b is disposed at the center of the fold line 6. The edge C1 of the upper end of the beverage can C enters the holes 3a, 3b, 3c. Further, a recessed portion 3 d that is recessed inward from the gusset portion 10 is formed on the lower surface portion 4 side of the side surface portion 3.

  Three can bottom holding portions 7 are arranged on a fold line 5 positioned between the side surface portion 3 and the lower surface portion 4. Two of the three can bottom holding portions 7 are disposed near both ends of the fold line 5, and the remaining one is disposed at the center of the fold line 5. The can bottom holding part 7 has a cutout part 7a formed in a U-shape and a bent part 7b connecting one end and the other end of the cutout part 7a. The can bottom holding part 7 has a cutout part 7a cut out when the beverage can C is wrapped on the wrapping paper 1, and a bent part 7b is bent inward (the back side of the paper surface in FIG. 2). Each beverage can C is held by entering.

  A pair of engaging projections 4a is formed at the end of the separated lower surface portion 4, and a pair of engaging holes 4b into which the respective engaging projections 4a enter is formed at the lower surface portion 4 of the other side. ing. The engaging protrusion 4a has a bent portion 4c located at the base thereof and an extended portion 4d expanded in a U shape at the tip. The engagement hole 4b has a long hole shape extending along the folding line 5, and the length of the engagement hole 4b is longer than the bending part 4c and shorter than the extension part 4d. Accordingly, by bending the bent portion 4c of the engagement protrusion 4a and pushing the expansion portion 4d into the engagement hole 4b, a state in which the expansion portion 4d is caught in the engagement hole 4b is realized. The wrapping paper 1 can be assembled as shown in FIG. 1 by engaging with the engaging holes 4b.

  Next, the gusset part 10 of the wrapping paper 1 will be described in detail. As shown in FIGS. 3 and 4, the gusset portions 10 are disposed at both ends of the side surface portion 3 in the extending direction of the folding line 6. The gusset part 10 is located on the inner side of the opening 1a, the bent part 11, and the outer side of the bent part 11 (on the side opposite to the side part 3 when viewed from the bent part 11). And a connecting portion 12 for connecting the two.

  The bent portion 11 is a portion extending downward from the hole portions 3 a and 3 c and is interposed between the side surface portion 3 and the connecting portion 12. A linear first perforation 13 is formed at the boundary between the bent portion 11 and the connecting portion 12, and a linear second perforation 14 is formed at the boundary between the bent portion 11 and the side surface portion 3. Yes. Holes 3 a and 3 c are formed above the bent portion 11, and a concave portion 3 d is formed below the bent portion 11, and the bent portion 11 can be bent along the second perforation 14. Yes. A notch 15 that is recessed inward is formed between the connecting portion 12 and the bent portion 11. Since the notch 15 is formed, the bent portion 11 is more easily bent.

  The connecting portion 12 extends downward from the upper surface portion 2 toward the bent portion 11. The connecting portion 12 is bent downward from a folding line 8 located at the boundary with the upper surface portion 2. Further, the side 12 a forming the holes 3 a and 3 c of the connecting portion 12 and the first perforation 13 extend in substantially the same direction and obliquely with respect to the second perforation 14. Therefore, when the bent portion 11 is bent inward along the second perforation 14 with the beverage can C inside the wrapping paper 1, as shown in FIG. It extends diagonally outside the beverage can C toward. As described above, the four connecting portions 12 obliquely extend outside the beverage can C, thereby preventing the beverage can C from falling off by the gusset portion 10.

  By the way, in a wrapping paper such as a six-can pack in which a plurality of beverage cans C are packaged together, the strength of the connection strength between the connecting portion and the bent portion in the gusset portion is important. Specifically, when the connection strength between the bent portion 11 and the connecting portion 12 is too strong, the breakage tends to occur between the bent portion 11 and the side surface portion 3 (second perforation 14) during the fall, and the bent portion is bent. If the connection strength between the portion 11 and the connecting portion 12 is too weak, the connecting portion 12 or the boundary portion (the first perforation 13) between the connecting portion 12 and the bent portion 11 is likely to break when dropped. In addition, as the beverage can C, a 350 ml can and a 500 ml can are typical, but the breakage problem is likely to occur particularly in the case of a 500 ml can.

  In the wrapping paper 1 of the present embodiment, the above-described problem is solved, and a state in which the connection strength between the bent portion 11 and the connecting portion 12 is good is realized. Below, the more concrete structure of the bending part 11 and the connection part 12 is demonstrated.

  First, the linear 1st perforation 13 which is a boundary of the bending part 11 and the connection part 12 is located in the linear 1st slit 13a and the both ends of the 1st slit 13a, and the bending part 11 and the connection part 12 Are formed by first connecting portions 13b and 13c. The first connecting portion 13b is located on the hole 3a, 3c side above the first slit 13a, and the first connecting portion 13c is located on the notch 15 side below the first slit 13a.

  The length of the 1st connection part 13b and the length of the 1st connection part 13c may mutually be the same, and may differ. However, the length of the first connecting portion 13b and the length of the first connecting portion 13c are preferably the same from the viewpoint of improving the strength against dropping. Moreover, the length of the 1st connection part 13b and the length of the 1st connection part 13c are 5.0 mm or more and less than 7.0 mm, Preferably they are 5.0 mm or more and less than 6.8 mm, More preferably, it is 6.0 mm. Above and below 6.8 mm.

  Further, as a more preferable form, the length of the first connecting portion 13b and the first connecting portion 13c is 6.1 mm to 6.4 mm, the length of the first slit 13a is 6.5 mm to 7.0 mm, the first sewing machine An example in which the total length of the eye 13 is 18.7 mm to 19.8 mm is given.

  Here, when at least one of the length of the first connecting portion 13b and the length of the first connecting portion 13c is less than 5.0 mm, the strength of the first perforation 13 is weakened and the connecting portion 12 is It becomes easy to break.

  The width B1 of the connecting portion 12 at the end portion 13d on the lower surface portion 4 side (first connecting portion 13c side) of the first slit 13a may be longer than the first connecting portions 13b and 13c, and on the upper surface portion 2 side. The width may be shorter than the width B2 of the connecting portion 12 of the end portion 13e on the upper surface portion 2 side in the first connecting portion 13b. Here, as a more preferable form, the width B1 of the connecting portion 12 in the end portion 13d is 6.6 mm to 7.6 mm and the width B2 in the end portion 13e is 7.8 mm to 9.4 mm. Is mentioned.

In addition, the linear second perforation 14 that is the boundary between the bent portion 11 and the side surface portion 3 has the second connecting portions 14a, 14c, 14e, and 14g and the second slits 14b, 14d, and 14f alternately arranged linearly. It is formed by lining up. Here, when the total length of the first connecting portions 13b and 13c is A (mm) and the total length of the second connecting portions 14a, 14c, 14e and 14g is B (mm) (A And B are positive real numbers),
0.435 ≦ (A / B) ≦ 0.650
Meet.

  Further, the upper limit of the value of (A / B) is preferably 0.630, more preferably 0.600, and still more preferably 0.570. On the other hand, the lower limit of the value of (A / B) is preferably 0.461 and more preferably 0.542. Here, as a more preferable form, the value of (A / B) is 0.435 ≦ (A / B) ≦ 0.569, and the total length of the second connecting portions 14a, 14c, 14e, and 14g is 22.5 mm. The example which is above and 24.0 mm or less is given. By making the total length of the second connecting portions 14a, 14c, 14e, and 14g 22.0 mm or more and 24.0 mm or less, the strength of the second perforation 14 can be improved. For example, if the total length of the second connecting portions 14a, 14c, 14e, and 14g is longer than 24.0 mm, the mechanical suitability with a machine that folds the bent portion 11 decreases.

  Here, when the value of (A / B) is less than 0.435, the strength of the first perforation 13 decreases. Further, when the value of (A / B) exceeds 0.650 and the above-described width B1 is longer than the length of the first joint portion 13c, the second perforation 14 is likely to be broken.

  As described above, in the gusset part 10, the balance between the strength of the bent part 11 and the strength of the connecting part 12 can be improved by making each element constituting the bent part 11 and the connecting part 12 as described above. It is possible to make the bent portion 11 and the connecting portion 12 more difficult to break. Here, as shown in FIG. 5 to FIG. 7, the drop test was performed as Examples 1 to 6 that satisfy the requirements of the above-described dimensions, and Comparative Examples 1 to 3 as examples that do not satisfy the requirements, and the gusset portion 10 was broken. An experiment was conducted to confirm whether or not. Below, the method of this drop test and the result of a test are demonstrated.

  First, as shown in FIGS. 5 (a) and 5 (b), in this test, four packaged products 100 are accommodated in a cardboard box D with the upper surface part 2 facing upward, It arrange | positions above the shock absorbing material K in the state maintained so that it might become horizontal. At this time, the cardboard box D is arranged so that one short side D1 of the cardboard box D enters the inside of the cushioning material K in a plan view. Then, as shown in FIG. 5C, the cardboard box D is dropped to give a drop impact to the packaged product 100 on the short side D1 side, and the gusset portion 10 is broken at the four places P located on the short side D1 side. The presence or absence was confirmed.

  Moreover, the specification of Example 1- Example 6 and Comparative Examples 1-3 is described in FIG. In FIG. 6, the total length (mm) is the total length of the first perforation 13 that is the gusset connecting portion, the left side of the three rows of “perforation pitch” is the length of the first connecting portion 13 b, and the center is the first slit. The length of 13a and the right side are the length of the 1st connection part 13c.

  In FIG. 6, the gusset width (mm) is the width of the connecting portion 12, B1 is the width B1 of the connecting portion 12 at the end 13d on the lower surface portion 4 side of the first slit 13a, and B2 is on the upper surface portion 2 side. This is the width B2 of the connecting portion 12 of the end portion 13e on the upper surface portion 2 side in the first connecting portion 13b. Further, the gusset folding portion is the bending portion 11, and the numbers of the perforation pitch are, from the left, the second connecting portion 14a, the second slit 14b, the second connecting portion 14c, the second slit 14d, the second connecting portion 14e, Each length of the 2nd slit 14f and the 2nd connection part 14g is shown. In Examples 4 to 6 and Comparative Example 3, a slit is further provided on the recess 3d side of the second connecting portion 14g. Further, the total length of the gusset turn-up portions indicates the total length of the second connecting portions 14a, 14c, 14e, and 14g.

  As a result of performing the drop test of FIG. 5 on Examples 1 to 6 and Comparative Examples 1 to 3 shown in FIG. 6, the results shown in FIG. 7 were obtained. In FIG. 7, the drop test of FIG. 5 is performed 4 times and the result of having confirmed 16 gusset parts 10 by performing 16 places or 5 times is shown. Of the gusset breakage occurrence rate in FIG. 7, the cut of the connecting portion is the occurrence rate of the cut of the connecting portion 12, and those with (horizontal) indicate the occurrence rate of the connecting portion 12 being cut in the width direction. Yes. The cut | disconnection on a connection part has shown the generation | occurrence | production rate of the cut | disconnection of the part adjacent to the hole 3a, 3c of the connection part 12, ie, the hole 3a, 3c. The top surface-gusset connecting portion cutting indicates the occurrence rate of cutting of the boundary portion (the folding line 8 portion) between the connecting portion 12 and the upper surface portion 2, and the folded portion cutting is the occurrence of cutting of the bent portion 11. Shows the rate.

  As shown in FIG. 7, first, in Comparative Example 1 in which the value of (A / B) described above exceeds 0.650 and the width B1 is longer than the length of the first connecting portion 13c, The incidence of breakage was 31.25%. On the other hand, the fracture | rupture of the bending part 11 was not seen in Examples 1-6 in which the length of the 1st connection parts 13b and 13c is less than 7.0 mm.

  On the other hand, in Comparative Example 2 in which the lengths of the first connecting portions 13b and 13c are 3.3 mm, the occurrence rate of breakage of the connecting portion 12 was 55%. Further, in Example 6 where the length of the first connecting portions 13b and 13c is 5.3 mm, the fracture occurrence rate of the connecting portion 12 was 10%, but the length of the first connecting portions 13b and 13c was 5%. The result was better than when the thickness was less than 0.0 mm. In Examples 1 to 5 in which the lengths of the first connecting portions 13b and 13c are 6.1 mm to 6.4 mm, the occurrence rate of breakage of the connecting portion 12 is 5% or less, which is a better result.

  Moreover, in the comparative example 3 whose length of the 1st connection part 13b is 7.9 mm, the incidence rate of the fracture | rupture above the connection part 12 was 15%. When the difference between the length of the first connecting portion 13b and the length of the first connecting portion 13c is large as in the comparative example 3, the difference in strength between the first connecting portion 13b and the first connecting portion 13c becomes large. Therefore, it turned out that a fracture | rupture is easy to produce. On the other hand, as in Examples 1 to 6, it was found that breakage hardly occurred when the lengths of the first connecting portion 13b and the first connecting portion 13c were made similar.

  Next, functions and effects of the wrapping paper 1 and the packaged product 100 according to this embodiment will be described. First, according to the wrapping paper 1, the connecting portion 12 and the bent portion 11 are continuous via the first perforation 13 and are connected by the two first connecting portions 13 b and 13 c of the first perforation 13. Yes. And the connection strength of the connection part 12 and the bending part 11 can be made favorable by making each length of the two 1st connection parts 13b and 13c more than 5.0 mm and less than 7.0 mm. Therefore, the connection part 12 and the bending part 11 can be made difficult to break when the packaged product 100 falls. Therefore, the strength of the gusset portion 10 against dropping can be increased. Furthermore, since the packaging product 100 includes the wrapping paper 1 and the beverage can C packaged with the wrapping paper 1, the packaging product 100 in which the strength of the gusset portion 10 against dropping can be provided.

  The width B1 of the connecting portion 12 at the end portion 13d on the lower surface portion 4 side of the first slit 13a may be longer than the lengths of the first connecting portions 13b and 13c, and the first connecting portion on the upper surface portion 2 side. 13b may be shorter than the width B2 of the connecting portion 12 of the end portion 13e on the upper surface portion 2 side. In this case, the width of the connecting portion 12 becomes narrower from the upper surface portion 2 side toward the lower surface portion 4 side. Further, the width B1 of the connecting portion 12 at the end portion 13d on the lower surface portion 4 side of the first slit 13a is longer than the lengths of the first connecting portions 13b and 13c, so that the width of the connecting portion 12 can be increased. It is possible to make it difficult to concentrate the impact force on the portion 12. Therefore, the breakage of the connecting portion 12 can be more reliably suppressed.

  The second perforation 14 is formed by alternately arranging the second slits 14b, 14d, 14f and the second connecting portions 14a, 14c, 14e, 14g in a straight line, and the first connecting portions 13b, When the total length of 13c is A (mm) and the total length of the second connecting portions 14a, 14c, 14e, and 14g is B (mm), 0.435 ≦ (A / B) ≦ It satisfies 0.650. The total length of the first connecting portions 13b and 13c that connect the connecting portion 12 and the bent portion 11, and the total length of the second connecting portions 14a, 14c, 14e, and 14g that connect the bent portion 11 and the side surface portion 3. With the above relationship, the balance between the strength of the connecting portion 12 and the strength of the bent portion 11 can be improved. Therefore, the connection part 12 and the bending part 11 can be made more difficult to break, and the strength against dropping can be further increased.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above, What was changed in the range which does not change the summary described in each claim, or applied to others It may be.
