JP4314329B2 - Packaging box assembly that can be easily divided into packaging boxes - Google Patents

Description

  The present invention relates to a packaging box material, a packaging box, and a packaging box assembly, and in particular, beverage containers for alcoholic beverages such as whiskey, beer, and liqueur and soft drinks, and cylindrical cans (including bottle cans). The present invention relates to a packaging box material, a packaging box, and a packaging box assembly for collectively packaging containers and bottles (including PET bottles).

In recent years, an increasing number of consumers purchase beverage containers as packaging boxes. Conventionally, six packaging boxes (multipack) have been used, but some consumers think that this is a small number. For this reason, in large-volume retailers of beverage products, it is becoming mainstream for consumers to purchase the entire cardboard case containing 24 beverage containers.
However, on the other hand, there is a persistent demand for packaging boxes that are fewer than 24 and larger than 6 multipacks. This is because the volume and weight of the consumer are excessive when transporting after purchase. However, such a cardboard packaging box having a size that has not been used in the past has many disadvantages in the physical distribution process, such as a reduction in packing efficiency, and is not currently used. If more than six packaging boxes are produced, the strength of the thin paper used in the conventional multipack will be insufficient. For this reason, it is necessary to use a packaging material excellent in strength.

In view of such a situation, it is required that an existing volume packaging box can be divided into several boxes. For example, the following has already been disclosed as a packaging box capable of dividing one box into two at a store. First, as a first example, as shown in FIG. 5, a perforation 103 is formed in a packaging box 101 composed of a first box portion 101A and a second box portion 101B (patent) Reference 1 and Patent Document 2). That is, in the box making process, the packaging box 101 is formed as one. And after packaging, each box part 101A and 101B is cut | disconnected from the perforation 101 at a shop etc. as needed, and it divides into two.
However, in these conventional splittable packaging boxes 101, the first box portion 101A and the second box portion 101B are merely engaged by the perforation 103 as described above. For this reason, when the packaging box 101 is lifted, the perforation 103 may be bent by the weight of the entire box, and in some cases, the perforation 103 may be partially broken.

  In addition, another example of a packaging box is also disclosed in order to prevent bending and tearing at the perforation 103 as described above (see Patent Document 3). Although the perforation for a division | segmentation is formed, a box is made into a double structure through a reinforcement member inside the side wall of a packaging box. As another example, there is a structure in which a flap-like piece of paper is folded and inserted toward the adjacent box portion, and slits and reinforcing pieces are used to improve strength. These packaging boxes are those that are relatively light in contents, such as those that contain packaging packs such as strawberries and daikon radishes, and are used as a single packaging box during transportation and storage, and small at the store. It can be divided into two boxes.

  However, as described above, in the case of the packaging box that is engaged only by the perforation, there are problems such as bending or tearing of the perforation. Further, in the case of a packaging box having a double structure, there is a problem that the structure becomes extremely complicated. Furthermore, in the case of a conventional packaging box engaged with perforations, it is possible to divide at the store etc. if necessary, but in order to divide the packaging box, all perforations on the outer periphery of the packaging box are cut.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1A shows a development view of the packaging box material 1. As shown in this figure, the packaging box 1 is composed of four rectangular side wall portions 3, 5, 7, and 9, four upper lid portions 3a, 5a, 7a, and 9a, and four lower lids. It consists of parts 3b, 5b, 7b, 9b. A connecting portion 7 c for connecting to the side wall portion 9 is provided at the end of the side wall portion 7. When assembling the packaging box material 1 as a packaging box, it is bent along the dotted line in the figure, and a cube is formed with the connecting member 7c, and the bottom surface is sealed with the lower lid portions 3b, 5b, 7b, 9b. Here, the material of the packaging box material is, for example, cardboard paper, but is not limited thereto, and may be another cardboard material, plastic material, or the like.
Each component of the packaging box material 1 of this invention is demonstrated in detail below. Each side wall part 3, 5, 7, 9 is connected in order. The heights of the side wall portions 3, 5, 7, and 9 are all substantially equal to form a box-like body. When the packaging box material 1 is assembled into a cube, among the side wall portions 3, 5, 7, and 9, the pair of side wall portions 3 and 7 face each other, and the pair of side wall portions 5 and 9 face each other. . Accordingly, the pair of side wall portions 3 and 7 and 5 and 9 facing each other have substantially the same shape and size. In addition, each side wall part 3,5,7,9 is cut out from one material, and is bend | folded at each boundary line.

Further, upper lid portions 3a, 5a, 7a, and 9a are connected to the upper portions of the side wall portions 3, 5, 7, and 9, respectively. Each upper lid portion 3a, 5a, 7a, 9a has a width substantially equal to that of the corresponding side wall portions 3, 5, 7, 9 and is a boundary line (dotted line) with the side wall portions 3, 5, 7, 9 ) To bend. Although the height of the upper lid portions 3a, 5a, 7a, 9a can be freely selected, in this embodiment, the upper upper lid portions 3a, 7a connected to the side wall portions 3, 7 are described later. It is set to about half the width W of the side wall portion 5 so that the upper surface of the packaging box 1A to be sealed can be sealed. The upper lid portions 3a, 5a, 7a, and 9a are cut out from the material integrally with the corresponding side wall portions 3, 5, 7, and 9, and are bent at each boundary line. Moreover, since the upper surface of the packaging box can be sealed with the upper lid portions 3a and 7a, the upper lid portions 5a and 9a may be omitted.
Further, lower lid portions 3b, 5b, 7b, and 9b are connected to the lower portions of the side wall portions 3, 5, 7, and 9, respectively. Each of the lower lid portions 3b, 5b, 7b, 9b has substantially the same shape and size as the upper lid portions 3a, 5a, 7a, 9a, and can seal the bottom surface of the packaging box. Yes. As in the case of the upper lid portions 3a, 5a, 7a, 9a, the packaging box can be sealed with the lower lid portions 3b, 7b, so that the upper lid portions 5b, 9b may be omitted.

Next, the notches 15, 17, 19, and 21 formed in the packaging box material 1 will be described. In the present embodiment, two notches (first notches) 15 and 17 are formed in the vertical direction along the boundary line L ₁ with the adjacent sidewall portions 5 and 9 at the left and right ends on the upper side of the sidewall portion 3. Has been. The width of the first notches 15 and 17 is set to be equal to or less than the thickness of the engaging member (see FIGS. 1B and 1C) that fits into the notches 15 and 17. However, in order to ensure the ease of insertion, it is preferable that the thickness is at least about half of the thickness of the engaging member. Further, the depth of the first notches 15 and 17 is set to, for example, about half the height of the side wall portion 3. This is to prevent the strength of the packaging box material 1 from being reduced so much. However, the depth of each notch 15 and 17 is an example, and if the strength required according to the strength of the material to be used and the weight of the contents to be packed can be ensured, the height of the side wall portion 3 is increased. It is also possible to make it about half or less.
In addition, the packing box member 1, the notch (-out second notch) the two in the horizontal direction along the boundary line L ₂ of the upper lid portion 3a corresponding thereto and sidewall portion 3 19 and 21 are formed ing. The second notches 19 and 21 are also the same depth as the first notches 15 and 17 in the vertical direction. However, as in the case of the first notches 15 and 17, the depth of the second notches 19 and 21 is also appropriately determined according to the required strength. Note that predetermined inclined portions 19a and 21a are formed on the upper lid portion 3a side at the entrances of the second notches 19 and 21. This is because the engagement members 35 and 37 (see FIGS. 1B and 1C), which will be described later, can be easily inserted into the second notches 19 and 21.

The notches 15, 17, 19, and 21 formed in the packaging box material 1 do not need to be exactly along the boundary lines L ₁ and L ₂ , and in order to ensure ease of assembly, the boundary lines It may be formed slightly shifted from L ₁ and L ₂ . For example, as shown in the figure, the second horizontal cutouts 19 and 21 are formed slightly above the upper ends (dotted lines) of the side wall portions 5 and 9. This is to prevent the side wall portions 5 and 9 from getting in the way when the second engaging members 35 and 37 are inserted into the assembled packaging box.
Further, as described above, the packaging box material 1 of the present embodiment has the first notches (vertical direction) 15 and 17 and the second notches (horizontal direction) 19 and 21 at the upper corners of the side wall portion 3. However, the present invention is not limited to this. That is, only the first cutout 15 and the second cutout 19 may be formed only at one corner of the side wall portion 3. As described above, when the notches 15 and 19 are formed only on one side, the engagement strength when the two packaging boxes are engaged is lowered as compared with the case where the notches are formed on both sides. If it is a thing, it may be able to withstand sufficient use.

FIG. 1B shows the first engaging members 31 and 33 inserted into the first cutouts 15 and 17 in the vertical direction, and FIG. 1C shows the second engagement member in the horizontal direction. The 2nd engaging members 35 and 37 inserted in the notches 19 and 21 are shown, respectively. Each engagement member 31, 33, 35, 37 is a rectangular plate. The size of each engaging member 31, 33, 35, 37 is determined by the size of the packaging box material 1. Here, for example, as shown in FIG. 1B, the vertical length of the first engaging members 31 and 33 is a, and the horizontal length is b. And if the width of the side wall portions 5 and 9 of the packaging box material 1 is W as described above and the height (corresponding to the depth of the packaging box) is D (see FIG. 1 (A)),
a ≦ D
b ≦ 2W
Meet the relationship. In the case of the second engagement members 35 and 37, the horizontal length is limited to be equal to b of the first engagement member, but the vertical length is limited to the depth of the packaging box. There is nothing.
The material of the engaging members 31, 33, 35, and 37 is preferably the same cardboard material as the packaging box material 1 as described above, but may be a different material (for example, a plastic material or the like). Each engaging member 31, 33, 35, 37 is formed with a predetermined engaging notch 31 a, 33 a, 35 a, 37 a along the direction perpendicular to the longitudinal direction at the center in the longitudinal direction. In the present embodiment, one engagement notch 31a, 33a, 35a, 37a is formed in each engagement member 31, 33, 35, 37, but the present invention is not limited to this, You may make it form two or more engagement notches in each engagement member 31,33,35,37, respectively. Engagement notches 31a, the depth of 33a is slightly shorter than the length of each of the boundary L ₁ between the sidewall portion 3 and the side wall portions 5,9. In addition, a predetermined inclined portion is formed at the entrance of the engagement notches 31a, 33a, 35a, and 37a of the engagement members 31, 33, 35, and 37 to facilitate insertion into the packaging box. However, this is not an essential component for the present invention.

Next, a packaging box 1A assembled using the packaging box material 1 will be described with reference to FIG. FIG. 2 is a perspective view showing a packaging box 1A according to the present embodiment. In this figure, the members constituting the packaging box 1A are shown as having no thickness, but as described above, they are made of corrugated cardboard or the like, and needless to say, they have a predetermined thickness. 2 shows one packaging box 1A for convenience of explanation, but actually, two packaging boxes shown in FIG. 2 are engaged to form a packaging box assembly (see FIGS. 3 and 4). In some cases, this point will be described later.
As can be seen from FIG. 2, when the packaging box 1A is assembled, the bottom surface is sealed by the lower lid portions 3b, 5b, 7b, 9b (see FIG. 1). And this packaging box 1A wraps a canned drink etc. in this embodiment. As described above, the side surface of the packaging box 1 </ b> A is composed of two opposing pairs of side wall portions 3 and 7 and 5 and 9. In the figure, the upper lid portions 3a, 5a, 7a, and 9a are opened. However, when products or the like are actually packaged, they are sealed with these upper lid portions 3a, 5a, 7a, and 9a and are substantially hexahedrons. Shape. Thus, the packaging box 1A according to this embodiment functions as a packaging box alone.

Next, based on FIG. 3, an example when the packaging boxes 1A ₁ and 1A ₂ according to the present embodiment are engaged to form the packaging box assembly 1B will be described. Here, the structures of the packaging box 1A ₁ and the packaging box 1A ₂ are exactly the same. First, as shown in the figure, two packaging boxes 1A ₁ and 1A ₂ are arranged adjacent to each other. At this time, in each of the packaging boxes 1A ₁ and 1A _2, a packaged item may be accommodated or may be empty without being accommodated. The side wall portions 3 and 3 on the side where the above-described notches 15, 17, 19, and 21 are formed are arranged so as to face each other. Then, toward the one package box 1A ₁ contacting both by moving the other packing box 1A ₂ (broken line 1 in the figure). By this, the the notch 15, 19 of one packaging box 1A ₁ and the other notch 17, 21 of the packing box 1A ₂ adjacent.

Next, the first engaging member 31 is inserted toward the first notches 15 and 17 of the packaging boxes 1A ₁ and 1A ₂ (broken line 2 in the figure). At this time, the notches 15 and 17 of the packaging boxes 1A ₁ and 1A ₂ and the engaging notches 31a of the first engaging member 31 are inserted so as to fit each other. Thus, the packing box 1A ₁ the notch 31a for engagement of the engaging member 31, 1A ₂ wall portions (boundary line L ₁ region between sidewall portions) enters, which the first packing box 1A _1, 1A ₂ simultaneously The engaging member 31 enters the notches 15 and 17 of one. Here, the width of the engagement notch 31a of the engagement member 31 is set to be equal to or less than the total thickness of the packaging box members fitted into the engagement notch 31a. That is, in the present embodiment, the thickness is equal to or less than the total thickness of the two packaging box members fitted into the engagement notches 31a. Therefore, when the engaging member 31 is inserted into the packing box 1A _1, 1A _2, 2 two packing box 1A _1, 1A ₂ is firmly engaged. Here, in order to increase the engagement strength, it is narrower than the total thickness of the two packaging boxes to be fitted (for example, equivalent to the thickness of one piece of material), and in order to increase the ease of insertion It is desirable that the total thickness of the two packaging box materials to be fitted is about. Similarly, the first engagement member 33 is inserted into the notch on the opposite side (dashed line 3 in the figure). Thereby, both packaging boxes 1A ₁ and 1A ₂ are not separated in the horizontal direction.
Engaging members 31 and 33, the packaging box 1A _1, when fully inserted into 1A _2, the side wall portion upper end of the packaging box 1A _1, 1A ₂ of the engaging members 31 and 33 3,5,7,9 It is formed so as to be at a position equivalent to or lower than that. For this reason, these engaging members 31 and 33 do not obstruct the opening and closing of the upper lid portions 3a, 5a, 7a and 9a. The packaging box 1A ₁ and 1A ₂ at when the packaged articles are not accommodated, accommodating the article to be packaged in a packaging box 1A ₁ and 1A _2.

Next, the second engagement member 35 is inserted into the packaging boxes 1A ₁ and 1A ₂ (broken line 4 in the figure). That is, the second engaging member 35 is inserted into the second notches 19 and 21 formed in the horizontal direction in the packaging boxes 1A ₁ and 1A ₂ as shown in the drawing. Upon insertion of the engaging member 35 in the packaging box 1A _1, 1A _2, the boundary line of the wall portion (side wall portion 3 of the engaging packing box in the notch 35a 1A _1, 1A ₂ of the engaging member 35 and the upper lid portion 3a L ₂ region) enters, and at the same time, the engaging member 35 enters the notches 19 and 21 of the packaging boxes 1A ₁ and 1A ₂ . Further, the opposite engagement member 37 is inserted in the same manner (dashed line 5 in the figure). Then, after closing the upper lid portions 5a and 9a, the upper lid portions 3a and 7a are closed.
In addition, although the insertion order of each engaging member 31, 33, 35, 37 is an example for convenience of explanation to the last, when engaging after packing materials to be stored in the packaging boxes 1A ₁ and 1A ₂ in advance, The insertion order of each engagement member 31, 33, 35, 37 is not particularly limited. However, when engaging before storing the packaged object, only the first engaging members 31 and 33 are inserted as described above. This is because the second engaging members 35 and 37 are inserted in the horizontal direction, and are easily disturbed if inserted before the packaged article is accommodated.

FIG. 4 is a perspective view showing the packaging box assembly 1B in a state where the two packaging boxes 1A ₁ and 1A ₂ are engaged and the upper lid portions 3a and 7a are closed. As shown in the figure, when the upper lid portions 3a and 7a are closed, the engaging members 31 (33), 35 and 37 are inside the upper lid portions 3a, 5a, 7a and 9a. The boxes 1A ₁ and 1A ₂ will not escape. Then, the engagement members 31 (33) prevent the packaging boxes 1A ₁ and 1A _{2 from} being separated from each other in the horizontal direction. In addition, the engaging members 35 and 37 suppress the relative movement of the packaging boxes 1A ₁ and 1A _{2 in} the vertical direction. The size of the packaging box assembly 1B engaged in this manner was the same as the size of the packaging box used conventionally.

As already described, the packaging box assembly 1B of the present embodiment can engage the two packaging boxes 1A ₁ and 1A ₂ side by side, but each of the packaging boxes 1A ₁ and 1A ₂ can be used alone or as a packaging box. Needless to say, it functions as. Therefore, during distribution, the product is transported in the state of the packaging box assembly 1B in which the two packaging boxes 1A ₁ and 1A ₂ are engaged, and sold at the store etc. so as to be divided into _two packaging boxes 1A ₁ and 1A ₂ for display. A method is also possible. Moreover, even if it divides | segments once, it can engage again by the engaging members 31, 33, 35, and 37, Therefore It is possible to select and use an engagement state and a division | segmentation state according to the objective.

Here, a method for dividing the packaging boxes 1A ₁ and 1A ₂ will be described. In the case of the packaging box assembly 1B described in the above embodiment, the upper lid portions 3a, 5a, 7a, 9a can be opened, and the engaging members 31, 33, 35, 37 can be extracted and divided. In this case, it is possible to re-engage the packaging boxes 1A ₁ and 1A ₂ by reusing the engaging member. However, it is also possible to divide without opening the upper lid portion by providing a perforation at the center of the engaging members 31, 33, 35, 37, or cutting this portion with a cutter or the like. If it does in this way, the aesthetics of a packaging box will not be spoiled. However, in this case, when it is desired to re-engage the packaging boxes 1A ₁ and 1A ₂ , it is necessary to use a new engaging member. Separately from this, the upper lid portions 5a and 9a are omitted, so that the upper lid portions 3a and 7a seal the upper surface and assemble as a packaging box. A gap is formed through which 37 can be taken out. Therefore, the upper lid portion 3a of the packaging box 1A _1, 1A _2, without opening the 7a, it is possible to divide the packing box 1A _1, 1A _2.
Thus, when distributing to a store, it can be distributed as a packaging box assembly by the same system as a conventional packaging box, and can be easily divided into individual packaging boxes in the store. For this reason, it can respond to a consumer's request flexibly.

Moreover, the said embodiment demonstrated the case where two packaging boxes were used by engaging and dividing | segmenting. However, the present invention is not limited to this. For example, three or four packaging boxes may be engaged and divided for use. In this case, the notches for inserting the engaging members need to be formed not only at the two upper end portions of the side wall portion 3 but also at the two upper end portions of the side wall portion 7 as in the present embodiment. .
Moreover, although this embodiment demonstrated the case where each notch 15, 17, 19, 21 was formed in the upper cover part 3a, 5a, 7a, 9a side, this invention is not limited to this. Each notch may be formed on the lower lid portions 3b, 5b, 7b, 9b. In this case, the upper surface of the packaging box assembly has an appearance similar to that obtained by simply arranging two packaging boxes. However, if the packaging box assembly 1B of the above embodiment is turned upside down, the same effect can be obtained. Moreover, it becomes possible not only to arrange in parallel in the horizontal direction as described above but also to stack a plurality of packaging boxes in the vertical direction by engaging in the vertical direction. Such an engagement method is particularly useful when a large number of thin packaging boxes are stacked.

Although the packaging box and the packaging box assembly can be adapted to beverage containers of various capacities, the size of the packaging box assembly is not limited to the existing size packaging box (for example, 350 ml or 500 ml, particularly from the viewpoint of logistics). It is desirable to be equivalent to 24 plastic bottles and cans. However, about 4 to 24 containers with a capacity of about 250 to 500 ml can be sufficiently applied. Of course, it is possible to deal with the case of 24 or more with various capacities.
Further, a cardboard material such as corrugated paper is often used as a material constituting the packaging box. The thickness is about 3 to 5 mm when the beverage contains 350 ml. In the case of a 500ml beverage, it is desirable to use a thicker one. However, other materials can be used in consideration of strength.

  It can be divided into individual packaging boxes as needed at stores, etc., and by engaging this packaging box, it can be put in circulation as a packaging box assembly of the same size as conventionally used packaging boxes. Applicable to packaging boxes that can.
