The present disclosure relates to packaging materials for packaging beverage containers and methods of manufacturing beverage products.

2. Description of the Related Art Conventionally, various packaging materials are known for packaging beverage containers. Japanese National Publication of International Patent Application No. 8-508962 describes a carrier that accommodates six beverage cans. The carrier has a flat panel overlying the six beverage cans, and the lateral ends of the panel are formed with outer ribs bent obliquely downward. A V-shaped inner rib is formed between the two beverage cans in the central portion in the width direction of the panel. A rectangular reinforcing strip is fixed so as to cover the V-shaped inner rib.

Japanese Patent Publication No. 8-508962

The transport body described above requires a large amount of paper because it is necessary to prepare the panel and the reinforcing strip. Therefore, it is desirable to reduce the amount of paper used. Furthermore, since the reinforcing strips are fixed to the panel with an adhesive, equipment for applying the adhesive is required. Therefore, it is required to reduce the amount of adhesive used.

An object of the present disclosure is to provide a packaging material that can be lifted easily, has a simple shape, and can reduce the amount of paper and adhesive used, and a method of manufacturing a beverage product.

A packaging material according to the present disclosure is a packaging material for packaging a beverage container, and includes an upper end holding portion fixed to the upper end of the beverage container, and an upper end holding portion extending downward from the upper end holding portion to cover the side surface of the beverage container. a side covering portion extending along the periphery of the beverage container so as to cover it.

In this packaging material, the upper end holder is fixed to the upper end of the beverage container. The wrapper comprises a side covering covering the side of the beverage container, the side covering extending along the circumference of the beverage container. Therefore, the side covering portion extending along the outer periphery of the beverage container can be lifted and the shape can be simplified. The side covering extends downwardly from the upper end retainer. Therefore, since this packaging material can be formed from one sheet of paper in which the upper end holding portion and the side covering portion are continuous, the amount of paper used can be reduced. Further, since the upper end holding portion and the side surface covering portion are molded from a continuous sheet of paper, no adhesive is required, so that the amount of adhesive used can be reduced.

The side covering part may have a first side holding part and a second side holding part facing each other along the circumferential direction of the beverage container. The first lateral support may have a coupling part that couples to the second lateral support. The second side holding part may have a hole through which the coupling part is passed and to which the coupling part is coupled. In this case, the side covering portion has a first side holding portion and a second side holding portion facing each other, and the first side holding portion has a coupling portion coupled to the second side holding portion. Therefore, since the first side holding portion can be coupled to the second side holding portion along the circumferential direction of the beverage container, the side of the beverage container can be firmly held. Also, the second side holding part has a hole to which the joint part of the first side holding part is joined. Therefore, since the first side holding portion is joined to the second side holding portion by joining to the hole, the configuration relating to the joining can be simplified. Therefore, molding can be performed more easily.

The side covering portion may have a curved portion that curves along the circumferential direction of the beverage container. In this case, the curved portion of the side surface covering portion curves along the side surface of the beverage container to cover the side surface, so that the side surface of the beverage container can be firmly held.

The upper end holder is fixed to the upper ends of the plurality of beverage containers, and the plurality of beverage containers are arranged in a row in a state in which the upper end holder is fixed to the upper ends of the plurality of beverage containers. good too. In this case, since the plurality of beverage containers fixed to the upper end holding portion are arranged in a row, both sides of the beverage containers in a row can be easily gripped by hand.

A method for producing a beverage product according to the present disclosure is a method for producing a beverage product using a packaging material for packaging a beverage container, comprising the steps of: fixing an upper end holding portion of the packaging material to the upper end of the beverage container; and covering the side surface of the beverage container with a side covering portion of the packaging material extending downwardly from the portion holding portion.

In this beverage product manufacturing method, the upper end holding portion of the packaging material is fixed to the upper end portion of the beverage container. The side covering portion of the packaging material covers the side of the beverage container so as to extend along the periphery of the beverage container. Therefore, since the side covering portion extending along the outer periphery of the beverage container can be lifted, the shape can be simplified. The side covering portion extends downward from the upper end holding portion. Therefore, the packaging material can be formed from one sheet of paper in which the upper end holding portion and the side covering portion are continuous, so that the amount of paper used can be reduced. Further, by forming the packaging material from a single sheet of paper in which the upper end holding portion and the side covering portion are continuous, no adhesive is required, so the amount of adhesive used can be reduced.

According to the present disclosure, it is possible to make the shape easier to lift and to reduce the amount of paper used and the amount of adhesive used.

Embodiments of a packaging material and a method for manufacturing a beverage product according to the present disclosure will be described below with reference to the drawings. In addition, the packaging material and the method for manufacturing a beverage product according to the present disclosure are not limited to the contents of the embodiments described later. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and duplicate descriptions are omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated for easy understanding, and the dimensional ratios and the like are not limited to those described in the drawings.

FIG. 1 is a perspective view showing a packaging material 1 and a beverage product 100 according to an embodiment. A beverage product 100 comprises a packaging material 1 and a beverage container C packaged in the packaging material 1 . The beverage container C is, for example, a beverage can. Beverage cans may be, for example, short cans, long cans, demitasse cans, bottle cans, barrel-shaped cans, and Westwave cans. Beverage cans may be any of 135ml, 250ml, 335ml, 350ml, 355ml, 500ml, 700ml, 750ml, 1000ml, 2000ml and 3000ml cans. Thus, the type and size of the can are not particularly limited.

The beverage container C has, for example, a cylindrical side surface C1 and an upper end portion C2 located at the upper end of the beverage container C. As shown in FIG. A seam portion C3 is formed on the outer edge of the upper end portion C2 in plan view. As an example, the beverage container C has an inclined surface C4 between the side surface C1 and the seam portion C3, which is inclined in a direction in which the outer diameter of the beverage container C decreases as it goes upward. The side surface C1 has, for example, a cylindrical shape. In this case, the upper end portion C2 is located at the upper end of the cylindrical side surface C1, and the seam portion C3 is an outer edge of the upper end portion C2 and has an annular shape in plan view. However, the shape of the beverage container C is not limited to the above example, and can be changed as appropriate.

The packaging material 1 is made of, for example, one sheet of paper. As a result, the amount of paper used in the packaging material 1 can be reduced compared to a packaging material made up of a plurality of sheets of paper. Moreover, when the packaging material 1 is formed of one sheet of paper, it is possible to eliminate the need to apply an adhesive such as hot melt. As a result, it is possible to omit the arrangement of the adhesive coating device, so that the production equipment for the beverage product 100 can be simplified and the cost of the production equipment can be suppressed.

The packaging material 1 includes an upper end holding portion 2 fixed to the upper end portion C2 of the beverage container C, and a side surface covering portion 3 extending along the outer periphery of the beverage container C so as to cover the side surface C1 of the beverage container C. Prepare. The upper end holding part 2 is fixed to the upper ends C2 of the plurality of beverage containers C, for example. In a state in which the upper end holding part 2 is fixed to the upper ends C2 of the plurality of beverage containers C, for example, the plurality of beverage containers C are arranged in a line.

In this way, in the packaging material 1 and the beverage product 100, by arranging the plurality of beverage containers C in a row, it is possible to make the beverage product 100 easy to hold with one hand. The number of beverage containers C packaged by the packaging material 1 (fixed by the upper end holder 2) is, for example, three.

The upper end holding portion 2 has, for example, a top surface covering portion 2b that covers the top surface of the beverage container C, and an inclined portion 2c that extends obliquely downward from the top surface covering portion 2b. As shown in FIGS. 2 and 3, the top surface covering portion 2b includes, for example, a top surface portion 2d extending in a first direction D1 in which a plurality of beverage containers C are arranged, and a top surface portion 2d extending in the first direction D1 from the top surface portion 2d. and a protruding portion 2f protruding in the intersecting second direction D2. The second direction D2 is, for example, the width direction (transverse direction) of the plurality of beverage containers C arranged along the first direction D1.

The top surface portion 2d includes, for example, a pair of long sides 2g extending along the first direction D1 so as to straddle a plurality of beverage containers C, and a pair of long sides 2g extending along the second direction D2 at the ends of the long sides 2g in the first direction D1. It has an extending short side 2h. In this embodiment, the short side 2h indicates the root portion of the projecting portion 2s. The long side 2g has, for example, a bending line 2m and a cutting line 2p, and the cutting line 2p is formed between the pair of bending lines 2m. By forming the bending line 2m and the cutting line 2p between the top surface covering portion 2b and the inclined portion 2c, the inclined portion 2c can be easily bent with respect to the top surface covering portion 2b.

The upper end holding portion 2 according to this embodiment includes, for example, a perforation line 2x. As an example, the perforation line 2x extends along the first direction D1. For example, the upper end holding portion 2 has a pair of perforation lines 2x aligned along the second direction D2. Each perforation line 2x extends linearly, for example. With this cutout line 2x, the upper end holding part 2 can be easily broken along the first direction D1 with a finger or the like by breaking along the cutout line 2x. The protruding portion 2f protrudes, for example, from the top surface portion 2d in the second direction D2. As an example, the protruding portion 2f protrudes in a rectangular shape. The number of protrusions 2f for one beverage container C is, for example, two. In this case, the number of projecting portions 2f twice as many as the number of beverage containers C packaged by the packaging material 1 is formed. The two protrusions 2f arranged along the second direction D2 protrude in opposite directions.

The inclined portion 2c has an inclined covering portion 2j that covers the inclined surface C4 of the beverage container C, and a concave portion 2k that is recessed in the second direction D2 in the inclined covering portion 2j. The inclined covering portion 2j is, for example, a flat surface. Also, the inclined covering portion 2j may be a curved surface that curves outward of the beverage product 100. FIG. The recessed portion 2k is recessed obliquely downward, for example.

The upper end holding portion 2 has, for example, a slit 4 into which the seamed portion C3 of the beverage container C is inserted. The slit 4 is formed, for example, between the protrusion 2f and the recess 2k. The packaging material 1 has, for example, a pair of slits 4 arranged along the second direction D2. A pair of slits 4 aligned along the second direction D2 are aligned along the first direction D1. The number of sets is, for example, the same as the number of beverage containers C to which the upper end holder 2 is fixed.

The slit 4 has, for example, a cut portion 4b extending downward. The slit 4 has, for example, a pair of cut portions 4b arranged along the first direction D1. The pair of cut portions 4b extend in directions away from each other from the slit 4. As shown in FIG. That is, the pair of cut portions 4b are formed in a V-shape. The seam portion C3 can be easily inserted into the slit 4 by having the cut portion 4b.

The packaging material 1 has a boundary portion 5 between the upper end holding portion 2 and the side covering portion 3 . The boundary part 5 extends over the entire circumference of the plurality of beverage containers C, for example. The boundary portion 5 has, for example, an oval shape in plan view, and surrounds the plurality of beverage containers C in plan view. The boundary portion 5 has curved portions 5d that curve along the outer periphery of the beverage container C at one end and the other end in the first direction D1.

The boundary portion 5 has, for example, folding lines 5b and cutting lines 5c, and the folding lines 5b and the cutting lines 5c are arranged alternately. By forming the bending line 5b and the cutting line 5c at the boundary 5 between the upper end holding portion 2 and the side covering portion 3, the side covering portion 3 can be easily bent with respect to the upper end holding portion 2. can be done.

The side covering portion 3 extends downward from the upper end holding portion 2 . The side covering portion 3 has, for example, an oval shape in a plan view. As an example, the side covering part 3 extends over the entire circumference of the plurality of beverage containers C. As shown in FIG. The side covering part 3 covers the side surfaces C1 of the plurality of beverage containers C from both the first direction D1 and the second direction D2, for example.

The side covering portion 3 has curved portions 3b that curve along the outer periphery of the beverage container C at one end and the other end in the first direction D1. The side covering portion 3 has, for example, a band shape extending along the first direction D1 and the second direction D2. The width W of the side covering portion 3 is, for example, 1 cm or more and 10 cm or less. The width W may be 2 cm or more, 3 cm or more, 4 cm or more, or 5 cm or more. Also, the width W may be 8 cm or less, 7 cm or less, or 6 cm or less. Thus, the value of width W is not particularly limited. However, when the width W is 3 cm or less, the amount of paper used for the packaging material 1 can be further reduced.

A ratio of the width W to the height H of the beverage container C is, for example, 0.05 or more and 0.50 or less. The ratio may be 0.10 or more, 0.15 or more, 0.20 or more, 0.25 or more, or 0.30 or more. Also, the ratio may be 0.45 or less, 0.40 or less, or 0.35 or less. Thus, the ratio value is not particularly limited. However, when the said ratio is 0.25 or less, the usage-amount of the paper of the packaging material 1 can be reduced further.

The side covering portion 3 has, for example, a finger hook portion 3d. Since the side covering portion 3 has the finger hooking portion 3d, the packaging material 1 can be easily held by putting a finger on the finger hooking portion 3d of the side covering portion 3. FIG. The finger hooking portion 3d is formed in a concave shape at the lower end of the side covering portion 3, for example.

The finger hooking portion 3d is, for example, a curved portion recessed inside (upper side) of the side covering portion 3 . By forming the finger hooking portion 3d into a curved portion, it is possible to further reduce the sense of incongruity with the finger when putting the finger on the finger hooking portion 3d. The side covering portion 3 has, for example, a pair of finger hook portions 3d arranged along the first direction D1. The pair of finger hooks 3d arranged along the first direction D1 may be provided on both sides of the side surface covering portion 3 in the second direction D2, or may be provided on one side of the side surface covering portion 3 in the second direction D2. may have been

FIG. 4 is a perspective view when the packaging material 1 and the beverage product 100 are viewed along the first direction D1. FIG. 5 is a developed view of the packaging material 1. FIG. In FIG. 5, the solid lines other than the edges indicate the cut lines of the packaging material 1, and the broken lines indicate the folding lines. As shown in FIGS. 4 and 5, the side covering portion 3 has a first side holding portion 3f and a second side holding portion 3g facing each other along the circumferential direction of the beverage container C. As shown in FIGS.

4 and 5, the side covering portion 3 includes a pair of first side holding portions 3f arranged along the second direction D2 and a second side holding portion positioned between the pair of first side holding portions 3f. 3g. The first side holding portion 3f has a joint portion 3h that is joined to the second side holding portion 3g. The second side holding portion 3g has a hole portion 3j through which the connecting portion 3h is passed and to which the connecting portion 3h is connected.

For example, a bending line 3k is formed at the end of the connecting portion 3h opposite to the second side holding portion 3g. The connecting portion 3h includes an extending portion 3m extending along the outer peripheral surface of the beverage container C from the folding line 3k, and a narrow portion 3p that narrows from the end of the extending portion 3m opposite to the folding line 3k. , and a projecting portion 3q located on the opposite side of the narrow portion 3p from the extending portion 3m.

For example, the connecting portion 3h has a bending line 3s and a cutting line 3t between the extending portion 3m and the narrow portion 3p. The coupling portion 3h has, for example, a pair of bending lines 3s and a cut line 3t formed between the pair of bending lines 3s, and the cut line 3t protrudes to the opposite side of the second side holding portion 3g. It is convex. That is, the cut line 3t forms a protrusion 3z that protrudes toward the bending line 3s. The connecting portion 3h has a pair of bent portions 3v between the narrow portion 3p and the projecting portion 3q, and a cut portion 3w formed between the pair of bent portions 3v.

The second side holding portion 3g is connected to the upper end holding portion 2 via the connecting portion 6, for example. The connecting portion 6 is positioned at the end of the upper end holding portion 2 in the first direction D1. The upper end holding portion 2 has a projecting portion 2s that projects in the first direction D1, and the connecting portion 6 has a recessed portion 6b into which the projecting portion 2s is inserted. A slit 7 similar to the slit 4 is formed between the protrusion 2s and the recess 6b.

The slit 7 may have, for example, a pair of cut portions 7b extending downward like the slit 4, and the pair of cut portions 7b are arranged along the second direction D2.

For example, a bending line 8b and a cutting line 8c are formed at the boundary between the connecting portion 6 and the second side holding portion 3g. The bending lines 8b and the cutting lines 8c are arranged alternately, for example. As an example, bending lines 8b are formed at the ends in the second direction D2 and at the center in the second direction D2, and the cutting line 8c is formed between the two bending lines 8b arranged along the second direction D2. formed.

The second side holding portion 3g has, for example, a pair of holes 3j arranged along the second direction D2. Each hole 3j includes a first hole 3x located on the center side in the second direction D2 and a second hole 3y located on the end side in the second direction D2. For example, the length of the first hole portion 3x in the first direction D1 is longer than the length of the second hole portion 3y in the first direction D1.

The first hole portion 3x may have, for example, a pair of cut portions 3x1. As an example, the cut portion 3x1 is formed at each of one end and the other end in the longitudinal direction of the first hole portion 3x. The connecting portion 3h and the hole portion 3j are connected to each other by, for example, the protruding portion 3q entering the first hole portion 3x and the convex portion 3z entering the second hole portion 3y. The exemplary first side holding portion 3f and the second side holding portion 3g have been described above. However, as will be described later, the modes of the first side holding portion and the second side holding portion are not limited to the first side holding portion 3f and the second side holding portion 3g, and can be changed as appropriate.

Next, an example of a method for manufacturing the beverage product 100 according to this embodiment will be described. However, the manufacturing method of the beverage product 100 is not limited to the following examples. First, the unfolded packaging material 1 is prepared as shown in FIG. 5 (step of preparing the unfolded packaging material). Subsequently, the folding lines of the packaging material 1 are folded to form the packaging material 1 (step of forming the packaging material). In addition, the molding of the packaging material 1 may be performed by a machine, or may be performed manually.

Then, the upper end holding portion 2 of the packaging material 1 is fixed to the upper end portion C2 of the beverage container C (step of fixing the upper end holding portion). Further, the side surface C1 of the beverage container C is covered with the side surface covering portion 3 of the packaging material 1 (step of covering the side surface of the beverage container). At this time, by connecting the connecting portion 3h to the hole portion 3j and connecting the first side holding portion 3f to the second side holding portion 3g (step of connecting the first side holding portion to the second side holding portion), The entire circumference of the beverage container C may be covered with the side covering portion 3 .

The first side holding portion 3f may be coupled to the second side holding portion 3g before the packaging material 1 is attached to the beverage container C, or the packaging material 1 may be attached to the beverage container C ( For example, the first side holding portion 3f may be coupled to the second side holding portion 3g in a state in which the upper end holding portion 2 is fixed to the upper end portion C2. As described above, the order of the step of coupling the first side holding portion to the second side holding portion and the step of attaching the packaging material to the beverage container can be changed as appropriate. After the packaging material 1 is attached to the beverage container C as described above, the beverage product 100 is completed, and a series of steps of the method for manufacturing the beverage product 100 is completed.

Next, the effects obtained from the packaging material 1 and the beverage product 100 according to this embodiment will be described in detail. In the packaging material 1, the upper end holding portion 2 is fixed to the upper end portion C2 of the beverage container C. As shown in FIG. The packaging material 1 includes a side covering portion 3 that covers the side surface C1 of the beverage container C, and the side covering portion 3 extends along the outer periphery of the beverage container C. As shown in FIG. Therefore, the side covering portion 3 extending along the outer periphery of the beverage container C can be held and lifted by hands, and the shape can be simplified.

The side covering portion 3 extends downward from the upper end holding portion 2 . Therefore, since the packaging material 1 can be formed from one sheet of paper in which the upper end holding portion 2 and the side covering portion 3 are continuous, the amount of paper used can be reduced. Further, since the upper end holding portion 2 and the side surface covering portion 3 are molded from a continuous piece of paper, no adhesive is required, so the amount of adhesive used can be reduced.

The side covering portion 3 may have a first side holding portion 3f and a second side holding portion 3g facing each other along the circumferential direction of the beverage container C. As shown in FIG. The first side holding portion 3f may have a joint portion 3h that is joined to the second side holding portion 3g. The second side holding portion 3g may have a hole portion 3j through which the joint portion 3h is passed and to which the joint portion 3h is joined. In this case, the side covering portion 3 has a first side holding portion 3f and a second side holding portion 3g facing each other, and the first side holding portion 3f has a connecting portion 3h that joins the second side holding portion 3g. . Therefore, since the first side holding portion 3f can be coupled to the second side holding portion 3g along the circumferential direction of the beverage container C, the side C1 of the beverage container C can be firmly held. Further, the second side holding portion 3g has a hole portion 3j to which the joint portion 3h of the first side holding portion 3f is joined. Therefore, since the first side holding portion 3f is joined to the second side holding portion 3g by joining to the hole portion 3j, the structure relating to the joining can be made stronger.

In this embodiment, since the second side holding portion 3g connected to the upper end holding portion 2 via the connecting portion 6 is provided between the pair of first side holding portions 3f, the coupling mechanism of the side covering portion 3 is improved. It can look good. Further, since the pair of first side holding portions 3f are coupled to the second side holding portion 3g which is connected to the upper end holding portion 2 via the connecting portion 6, the beverage container is held by the upper end holding portion 2 and the side covering portion 3. Retention of C can be further strengthened.

As shown in FIG. 1, the side covering portion 3 may have a curved portion 3b that curves along the circumferential direction of the beverage container C. As shown in FIG. In this case, the curved portion 3b of the side surface covering portion 3 curves along the side surface C1 of the beverage container C to cover the side surface C1, so that the side surface C1 of the beverage container C can be held firmly.

The upper end holding portion 2 is fixed to the upper end portion C2 of the plurality of beverage containers C. In the state where the upper end holding portion 2 is fixed to the upper end portions C2 of the plurality of beverage containers C, the plurality of beverage containers C are arranged in a row. They may be arranged side by side. In this case, since the plurality of beverage containers C fixed to the upper end holding portion 2 are arranged in a row, both sides of the beverage containers C aligned in the second direction D2 should be shaped to be easily grasped with one hand. can be done.

In the method for manufacturing the beverage product 100 according to this embodiment, the upper end holding portion 2 of the packaging material 1 is fixed to the upper end portion C2 of the beverage container C. As shown in FIG. The side surface covering portion 3 of the packaging material 1 covers the side surface C1 of the beverage container C so as to extend along the outer circumference of the beverage container C. As shown in FIG. Therefore, since the side covering portion 3 extending along the outer periphery of the beverage container C can be lifted, the shape can be simplified.

The side covering portion 3 extends downward from the upper end holding portion 2 . Therefore, since the packaging material 1 can be formed from one sheet of paper in which the upper end holding portion 2 and the side covering portion 3 are continuous, the amount of paper used can be reduced. Furthermore, by forming the packaging material 1 from a single sheet of paper in which the upper end holding portion 2 and the side surface covering portion 3 are continuous, no adhesive is required, so that the amount of adhesive used can be reduced. can.

As described above, the aspects of the first side holding portion and the second side holding portion of the side covering portion 3 can be changed as appropriate. FIG. 6 shows a first side holding portion 13f and a second side holding portion 13g according to a modification. Note that a part of the configuration of the following modified example overlaps with a part of the configuration of the above-described embodiment, so redundant description will be omitted as appropriate.

As shown in FIG. 6, the side covering portion 3 may have a first side holding portion 13f and a second side holding portion 13g instead of the first side holding portion 3f and the second side holding portion 3g. good. In the example of FIG. 6, the connecting portion 6 is omitted. In the example of FIG. 6, the side covering portion 3 includes a first side holding portion 13f located on one side in the second direction D2 and a second side holding portion 13g located on the other side in the second direction D2.

The first side holding portion 13f has a coupling portion 13h coupled to the second side holding portion 13g, and the second side holding portion 13g has a hole 13j through which the coupling portion 13h is passed and coupled to the coupling portion 13h. The connecting portion 13h includes an extending portion 13m extending along the outer peripheral surface of the beverage container C from the bending line 3k, and a narrow portion 13p that narrows from the end of the extending portion 13m opposite to the bending line 3k. , and a protruding portion 13q protruding from the narrow portion 13p through the constricted portion 13r.

The second side holding portion 13g has, for example, a hole portion 13j extending along the height direction D3, and a cut portion 13k is formed at each of one end and the other end of the hole portion 13j. The connecting portion 13h and the hole portion 13j are connected to each other by, for example, the protruding portion 13q entering the hole portion 13j.

As described above, even in the side covering portion 3 having the first side holding portion 13f and the second side holding portion 13g according to the modified example, the first side holding portion 13f is held in the second side along the circumferential direction of the beverage container C. Since it can be combined with the portion 13g, the side face C1 of the beverage container C can be firmly held. Therefore, the same effects as in the case of having the first side holding portion 3f and the second side holding portion 3g can be obtained.

Furthermore, in the packaging material 1 including the side covering portion 3 having the first side holding portion 13f and the second side holding portion 13g according to the modification, one protruding portion 13q is inserted into one hole 13j, thereby Since the first side holding portion 13f can be connected to the second side holding portion 13g, the number of joints can be reduced, and the packaging material 1 and the beverage product 100 can be manufactured more easily.

FIG. 7 is a diagram schematically showing a first side holding portion 23f and a second side holding portion 23g according to a further modification. As shown in FIG. 7, the first side holding portion 23f has a coupling portion 23h coupled to the second side holding portion 23g, and the second side holding portion 23g has a hole portion 23j coupled to the coupling portion 23h.

The coupling portion 23h is arrow-shaped, and the hole portion 23j is T-shaped. The coupling portion 23h has an extension portion 23k extending in the second direction D2 and an extension portion 23m extending from the extension portion 23k. The extending portion 23k has a rectangular shape. The extended portion 23m includes protruding sides 23p protruding upward and downward from the extending portion 23k, a pair of inclined sides 23q extending from the pair of protruding sides 23p in a direction in which the pair of protruding sides 23p approach each other, and a pair of inclined sides 23q. intersect with tip 23r.

The hole 23j has a first portion 23s extending in the height direction D3 and a second portion 23t extending from the first portion 23s in the second direction D2. When the coupling portion 23h is coupled to the hole portion 23j, the extension portion 23m enters the first portion 23s and the extension portion 23k enters the second portion 23t.

For example, the length B of the joint portion 23h (extended portion 23m) in the height direction D3 is longer than the length A of the hole portion 23j (first portion 23s) in the height direction D3. Thereby, the coupling portion 23h can be firmly coupled to the hole portion 23j. A pair of cut portions 23v extending obliquely from each first portion 23s may be formed in the hole portion 23j. In this case, the connecting portion 23h can be easily inserted into the hole portion 23j.

Even with the side surface covering portion having the first side surface holding portion 23f and the second side surface holding portion 23g according to the modification, the same effects as those of the above-described examples can be obtained. Further, the first side holding portion 23f and the second side holding portion 23g can be configured more simply than the above-described example. Therefore, assembly of the packaging material 1 and attachment of the packaging material 1 to the beverage container C can be performed more easily by machine or by hand.

The packaging materials according to the embodiment and various modifications have been described above. However, the present disclosure is not limited to the above-described embodiments or various modifications, and may be further modified and applied to others. That is, the shape, size, number, material and arrangement of each part of the packaging material, and the content and order of the steps of the beverage product manufacturing method are not limited to the above-described embodiments or various modifications, and can be changed as appropriate. be.

For example, in the above-described embodiment, the upper end holding portion 2 having the perforation line 2x was described. However, the shape, number, and arrangement of the upper end holders 2 are not limited to the above-described embodiment. Furthermore, the wrapper may have a top edge retainer that does not have the perforation line 2x. For example, in the embodiment described above, an example was described in which the number of beverage containers C packaged by the packaging material 1 (fixed by the upper end holding portion 2) is three. However, the number of beverage containers C packaged by the packaging material may be, for example, 2 or more and 6 or less. That is, as shown in FIG. 8, the packaging material 21 may hold six beverage containers C arranged in a line. Further, the number of beverage containers C packaged by the packaging material may be 3 or more, 4 or more, or 5 or more, and the number of beverage containers C packaged by the packaging material may be 7 or more. and may be, for example, 10 or less. Thus, the number of beverage containers C packaged by the packaging material is not particularly limited.

In the embodiment described above, the packaging material 1 holding a plurality of beverage containers C arranged in a row has been described. However, as shown in FIGS. 9 and 10, the packaging material 31 may hold a plurality of rows of beverage containers C. FIG. The packaging material 31 includes a plurality of upper end holding portions 2 extending in the first direction D1 and arranged along the second direction D2, a side surface covering portion 3 covering so as to surround the side surfaces C1 of the plurality of rows of beverage containers C, and a connecting portion 32 positioned between the plurality of upper end holding portions 2 . The connecting portion 32 is, for example, a portion that connects the pair of inclined portions 2c to each other. As an example, the connecting portion 32 has a plurality of holes 32b arranged along the first direction D1. Even with this packaging material 31, effects similar to those of the packaging materials according to the above-described embodiments and various modifications can be obtained.

In the above-described embodiment, the first side holding portion 3f has the connecting portion 3h, the second side holding portion 3g has the hole portion 3j, and the connecting portion 3h enters the hole portion 3j to form the first side holding portion 3f. is coupled to the second side holding portion 3g. However, the manner in which the first side holding portion and the second side holding portion are coupled can be further modified. For example, the first side holding part and the second side holding part may be joined together with an adhesive such as a hot melt adhesive. An example in which the first side holding portion and the second side holding portion are bonded to each other with an adhesive will be described below.

FIGS. 11(a) and 11(b) are diagrams showing a side covering portion 43 having a first side holding portion 43f and a second side holding portion 43g which are joined together by an adhesive. As shown in FIGS. 11(a) and 11(b), the side covering portion 43 has an adhesive 45, and the first side holding portion 43f and the second side holding portion 43g are attached to each other with the adhesive 45 interposed therebetween. spliced. The adhesive 45 is, for example, hot melt adhesive. For example, the adhesive 45 is applied to the back surface of the first side holding portion 43f and the surface of the second side holding portion 43g.

For example, the paper flow line in the first side holding portion 43f and the second side holding portion 43g is the first direction D1 (the width direction and the vertical direction of the first side holding portion 43f and the second side holding portion 43g). However, even if the paper grains in the first side holding portion 43f and the second side holding portion 43g are in the second direction D2 (longitudinal direction and lateral direction of the first side holding portion 43f and the second side holding portion 43g), good. However, if the grain of the paper is in the second direction D2, there is a concern that the paper itself will stretch in the first direction D1 when the paper absorbs moisture such as dew condensation during display, resulting in a decrease in strength. On the other hand, when the grain of the paper is in the first direction D1, the paper can be prevented from stretching in the first direction D1, so there is an advantage that the strength of the paper is less likely to decrease.

The first side holding portion 43f has a coupling portion 43q coupled to the second side holding portion 43g, and the second side holding portion 43g has a hole 43j through which the coupling portion 43q is inserted and coupled with the coupling portion 43q. The coupling portion 43q is provided at the end of the first side holding portion 43f. The coupling portion 43q is, for example, a protruding portion that protrudes from a narrow portion 43p that narrows toward the end portion of the first side holding portion 43f. The first side holding portion 43f and the second side holding portion 43g are joined together by the joining portion 43q entering the hole portion 43j. The coupling portion 43q and the hole portion 43j function as a locking mechanism that locks the first side holding portion 43f and the second side holding portion 43g to each other.

As described above, the side covering portion 43 having the first side holding portion 43f and the second side holding portion 43g according to the modified example has the adhesive 45. As shown in FIG. By the way, when the first side holding portion 43f and the second side holding portion 43g do not have the lock mechanism described above and are joined to each other only with the adhesive 45, the end portion of the first side holding portion 43f is the second side holding portion. It may protrude from the portion 43g, and there is a concern that other objects may be caught on the protruding first side holding portion 43f. On the other hand, when the side covering portion 43 has a lock mechanism as described above, the first side holding portion 43f can be prevented from protruding from the second side holding portion 43g, so the above concerns can be resolved. Further, even if the adhesive 45 is peeled off, the locking mechanism can prevent the first side holding portion 43f from coming off the second side holding portion 43g.

Further, when the first side holding portion 43f and the second side holding portion 43g do not have the lock mechanism described above and are joined to each other only with the adhesive 45, the end portion of the first side holding portion 43f may be attached to the second side surface. In order to avoid protruding from the holding portion 43g, the adhesive 45 should be applied to the end portion of the first side holding portion 43f as much as possible (the left portion as far as possible in FIGS. 11(a) and 11(b)). can be considered. However, when trying to apply the adhesive 45 to the end portion of the first side holding portion 43f as much as possible, the adhesive 45 may protrude from between the first side holding portion 43f and the second side holding portion 43g. Also from the viewpoint of reducing this possibility, it is preferable that the first side holding portion 43f and the second side holding portion 43g have the lock mechanism described above.

The side covering portion 43 having the locking mechanism and the adhesive 45 has been described above, and the example in which the locking mechanism is composed of the connecting portion 43q and the hole portion 43j has been described. However, the aspect of the locking mechanism of the side covering portion 43 is not limited to the aspect including the coupling portion 43q and the hole portion 43j, and can be changed as appropriate.

Furthermore, in the above-described embodiment, the upper end holding portion 2 fixed to the upper portion of the beverage container C, and the upper end holding portion 2 extending downward from the upper end holding portion 2 of the beverage container C so as to cover the side surface C1 of the beverage container C. A packaging material 1 has been described which includes a side covering 3 extending along its perimeter. However, the packaging material according to the present disclosure may be a packaging material that includes only an upper end holding part that is fixed to the upper part of the beverage container C, or a packaging material that covers the side surface C1 of the beverage container C. The packaging material may include only the side covering portion extending along the outer periphery.

For example, a packaging material according to the present disclosure may be a packaging material that includes a side covering portion 43 having a locking mechanism and adhesive 45 as described above. In the case of this packaging material, if the first side holding portion 43f is adhered to the second side holding portion 43g with an adhesive 45 and locked by a locking mechanism (for example, if the connecting portion 43q is inserted into the hole 43j), the side covering portion 43 can be formed, the beverage container C can be easily attached to the packaging material. Moreover, in the above-described embodiments, the beverage container C, which is a beverage can, has been described. However, the packaging materials and beverage product manufacturing methods according to the present disclosure are also applicable to beverage containers other than beverage cans, such as barrels, bottles, and PET bottles.
