[Prior art]
In recent years, the purchase of beverages in containers such as cans as packaging boxes has been increasing, and there is a demand that these beverage containers be stored in refrigerators as packaging boxes and taken out one by one at the time of beverage. strong.
As a packaging box made of cardboard for bundling and packaging a plurality of beverage containers, a multipack and a cardboard box have conventionally been the mainstream. A multi-pack is a generic name for multiple containers, such as cans and bottles, that are packaged in cardboard, shrink film, plastic, etc. And full enclosure types are well known. In order to take out the container of both the multipack and the cardboard, it is usual to dismantle part or all of the packaging box, take it out by hand, and store it in a refrigerator. When placing beverage containers in refrigerators, many consumers handle packaging boxes as follows. In other words, in the case of a multi-pack, disassemble the entire packaging box before putting it in the refrigerator, take out the beverage container and put it in the refrigerator, and in the case of a cardboard box, disassemble part (mostly the flap part). The required number of beverage containers are taken out and placed in a refrigerator. All of these methods take time and effort to disassemble the packaging box and take out the beverage container, and do not satisfy the above-mentioned demands of putting the packaging box in a refrigerator and taking it out one by one at the time of drinking.
[0003]
On the other hand, the following is disclosed as a packaging box that makes it easy to take out a beverage can. A packaging box (Japanese Patent Application Laid-Open No. H11-171264) has been disclosed in which cans can be put into a vending machine in a continuous and efficient manner in a short time. The packaging box is provided with an opening 105 on a side surface 103 opposite to the side surface of the beverage can 101 as shown generally by 100 in FIG. 8, and the stored beverage can 101 can be taken out through the opening 105. Things. However, this packaging box is for continuously discharging the beverage cans 101, and is not intended to take out one by one in a state where the packaging boxes 100 are placed horizontally. In addition, in order to remove the beverage can 107 located at the back of the packaging box 100, it is necessary to insert a hand through the opening 105 or the U-shaped opening 106, or to tilt the packaging box 100 artificially. there were.

In the packaging box of Japanese Utility Model Application Laid-Open No. 55-153325, it is described that an opening through which a can rolls sideways is provided on the flap surface of a cardboard box and the can is continuously put into a column of a vending machine. .
In the packaging box of Japanese Utility Model Publication No. 1-13071, there is a problem of the packaging box disclosed in Japanese Utility Model Publication No. 55-153325, that is, the cuts are discontinuous with the upper and lower flaps in order to prevent the cuts from being broken during transportation. The inner flap is folded and turned to the outside to prevent a step and make it easier to roll.
The packaging box disclosed in JP-A-11-171264 has a drawback of the packaging box disclosed in Japanese Utility Model Laid-Open No. 55-153325, that is, the cans can be manually aligned to prevent the cans from being clogged at the opening. A feature is that a roller is attached near the opening to provide a hand insertion opening and to facilitate rolling. The packaging box disclosed in Japanese Utility Model Application Laid-Open No. 3-108676, in addition to the invention of the packaging box disclosed in Japanese Utility Model Application Laid-Open No. 55-153325, has a rolling guide plate for a can inside a corrugated cardboard so that it can roll smoothly. .
However, these packaging boxes are packaging boxes for continuously putting beverage cans into a vending machine, and do not solve the problem of the present invention of taking out one by one from the packaging box at the time of beverage.
[0005]
Packaging boxes in which the can is guided to the vicinity of the opening by using gravity to take out the can from the other cardboard box (Japanese Unexamined Patent Publication No. 10-230929, Japanese Utility Model Publication No. 3-129224, Japanese Utility Model Application No. 64-29121, Utility Model No. No. 2,527,584) is present, but is a vertical drop, and does not have a structure of rolling out.

It pulls out one or two pieces at a time, and the upper can is dropped by gravity.
In the packaging box disclosed in Japanese Utility Model Laid-Open No. 3-129224, cans are pulled out one by one in a horizontal direction and in a longitudinal direction. The same as the packaging box. However, at the corners of the cardboard surface on the upper surface or the lower surface of the stored can, cut lines are formed so as to divide the corners into two, and the opening is different in shape.
In the packaging box disclosed in Japanese Utility Model Application Laid-Open No. 64-29121, the cans are pulled out side by side and one by one in the longitudinal direction, and the upper cans fall due to gravity. The use of gravity drop is the same as that of the packaging box of JP-A-10-230929 or JP-A-3-129224, but a cutout line is provided at the corner of the cardboard surface on the upper or lower surface of the inner can. The shape of the opening is different.
In the packaging boxes disclosed in JP-A-10-230929, JP-A-3-129224, and JP-A-64-29121, the gap for putting a finger into the opening is small and difficult to remove. Therefore, in order to solve the above-mentioned problem, the packaging box disclosed in Utility Model No. 2527584 is characterized in that a cut-and-raised portion is provided. Since it stops on the raised part, it has enough space to put your fingers in, and at the same time, prevents falling hands from injuring your hands.
[0006]
[Problems to be solved by the invention]
None of the publications described in the above-mentioned publications is intended to put a package or the like in a refrigerator, for example, cool a beverage or the like in a container, and take out the cooled containers one by one.
The present inventor has conducted intensive studies on a packaging box in which a plurality of containers are loaded in a packaging box, and as a result, provided an opening with a stopper at one end of the packaging box and inclined the packaging box so that the opening was lowered. It was found that the method of moving the container by gravity was optimal.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a packaging box which can accommodate a plurality of cylindrical containers collectively and can be taken out one by one from an opening by being inclined.
Another object of the present invention is to provide a packaging box in which a part of a packaging box can be deformed to form a projection and the packaging box can be inclined by the projection.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the packaging box of the present invention employs the following configuration.
That is, the present invention is a packaging box for a cylindrical container, which is formed of a sheet-like box material and stores the cylindrical containers stacked in a horizontal direction.
One surface of the packaging box facing the side surface of the cylindrical container is a bottom wall, and end walls adjacent to both ends of the bottom wall are a first end wall and a second end wall,
At the lower part of the first end wall, an opening forming means is provided for forming an opening for taking out a stored cylindrical container sideways by separating a part of the box material from the packaging box,
A part of the opening formed by the opening forming means is provided with a stopper for preventing the cylindrical container from being continuously discharged,
The bottom wall is provided with protrusion forming means capable of forming a protrusion that makes the second end wall side of the bottom wall higher than the first end wall side.
As described above, when the user grasps and pulls out the cylindrical container remaining in the opening by the inclination forming means for inclining the bottom surface of the packaging box, the cylindrical container in the packaging box is moved to the opening by the action of gravity. Moving. The moved cylindrical container is not continuously discharged from the opening, but is continuously discharged by the stopper provided in the opening. In this way, the user can reliably and easily take out the cylindrical containers one by one from the packaging box.
[0008]
Any cylindrical container may be used as long as it is a cylindrical container such as a bottle, a can, and a plastic bottle.
The contents of this container are not limited to beverages, but since the packaging box of the present invention can be installed in a refrigerator as it is, it is preferable to use beer, water whiskey, soft drinks, etc. that are cooled and consumed. The box material is preferably cardboard or cardboard paper, but any material may be used as long as it is constructed so that the cut line (perforation) can be broken by hand. The characteristics of the cardboard need only be determined in consideration of the weight and size of the cylindrical container to be stored. In the case of a packaging box for storing regular-sized (350 ml) beverage cans, it is preferable to use cardboard of 18 points for 6 cans and 20 points for 8 cans for packaging, and a long-sized (500 ml) beverage can for packaging. In the case of a packaging box to be stored, it is preferable to use cardboard with 20 points for 6 cans and 24 points for 8 cans. Furthermore, when the cylindrical container is a 350-m1 can or a 500-m1 can and an 8-can packaging box, it is preferable to use aqua-coated paper suitable for printing and waterproofing at 18 to 24 points. In the case of a six-can packaging box, the thickness of the cardboard may be 18 to 20 points because the weight of the cylindrical container is somewhat small.
Although the packaging box of the present invention can be applied to cylindrical containers of various capacities, it is particularly preferable that the packaging box is easy to put in a refrigerator, about 350 × 6 to 10, and the optimal size is 350 ml × 8. A capacity of about 250 m1 or 500 m1 can be sufficiently applied to four to twenty-four, but is not limited to the above embodiment.
[0009]
In the packaging box for a cylindrical container, the box material of the bottom wall may be doubled from a back member and a front member, and a part of the front member may be cut off to be formed on the protrusion. .
It is possible to form the projection with a simple structure by using the bottom surface as a double structure and using the front and back members.
In this case, the protrusion has a triangular trapezoidal shape, and the front member has a fold defining two sides of the triangle, and extends along the two sides at a desired distance from the two sides. A cut line and a fold defining another side of the triangle may be formed, and the front member may be cut along the cut line to form the protrusion, or the protrusion may be a polygon. A cutout line extending along three sides of the square, and a fold formed on the other side of the square, and cutting the front member along the cutout line to form the protrusion. A part may be formed.
In the packaging box, the opening forming means may include a perforated cut line formed at the first end wall and at a boundary between the first end wall and a side wall adjacent to the first end wall. Or the opening forming means is formed by a perforated cut line formed on the first end wall and a side wall adjacent to the first end wall, and The side of the opening may be extended to the side wall so that the upper and lower end surfaces of the container can be grasped by hand.
Furthermore, in the packaging box of the cylindrical container, a hole for a handle may be provided in a bottom wall. This makes it easy to carry the packaging box of the present invention.
In particular, a preferred embodiment of the present invention is a form in which a handle hole is provided on the bottom surface having a double structure penetrating the front member and the back member.
Thus, by forming not only the protrusion but also the hole for the handle on the bottom surface having the double structure, the strong protrusion and the hole for the handle can be formed with a simple configuration. In addition, it is possible to simplify the packaging box, reduce the weight, and reduce the manufacturing cost.

It may be formed linearly at the boundary. Further, the second end wall has the same structure as the first end wall 10 except that a means for forming an opening is not provided, and thus a detailed description thereof is omitted.
[0018]
(Protrusion Forming Means 51) This will be described with reference to FIG. In this embodiment, the projection forming means 51 forms a projection 55 at a position close to the second end wall 40 side of the bottom wall, and the bottom wall 50 is inclined by the projection 55. The protrusion 55 has a double-walled structure of the cardboard of the bottom wall 50 of the back member 57 and the front member 59. A part of the front member 59 is cut along the perforation, and this is inserted into the back member 59. It is formed by being inserted into the portion 52.
FIG. 4A shows the bottom surface 50 on which the projection 55 is formed. In FIG. 4A, the near side is the first end wall side, and the far side is the second end wall 40 side. Of the members constituting the bottom wall 50, the upper side is the front member 59, and the lower side is the back member 57. FIG. 4B is an enlarged view of the formed protrusion 55.
[0019]
The configuration of the protrusion 55 formed by the protrusion forming means 51 will be described below.
With the center line 60 of the front member 59 as the center (substantially symmetrically), a bending line defining two upper edges 61 (two sides of the triangle) of the projection is formed so as to form a convex triangle toward the second end wall. A cutting line is provided outside the upper edge 61 to define a supporting edge 63 of the projection with a predetermined distance from the upper edge 61. The distance between the supporting edge 63 and the upper edge 61 is gradually enlarged toward the second end wall 40. The degree of enlargement is appropriately determined according to the degree that the packaging box 1 containing the cylindrical container is not crushed by the weight of the packaging box even when the packaging box 1 is inclined. Further, a cut-out line defining a convex insertion portion 65 is provided on the distal end side of the support edge 63 of the projection. These cut lines are formed as perforations in the front member 59, so that the protrusions can be separated from the surroundings. The line defining the other upper edge (the other side of the triangle) 69a and the line defining the support edge 69b of the triangular projection at the projection upper edge 61 are not perforated, and are easy to bend. Bend line.
[0020]
The back member 57 is provided with a pair of elongated or slit-shaped receiving portions 52 at positions corresponding to the insertion portions 65. The angle β formed by the ends of the pair of receiving portions 52 is substantially the same as the angle α formed by the ends of the upper edge 61.
The shape of the upper edge 61 of the projection is not limited to a triangle, but may be a trapezoid or a rectangle. Further, in order to facilitate separation of the perforations of the projections, the front member 59 has semicircular holes 62 on the left and right outside the support edge 63 and a pentagonal shape on the outside of the support edge 67. Hole 68 is cut out.
[0021]
The formation of the projection 55 will be described below with reference to FIG.
First, a cut line (formed by perforation) defining the support edge 63, the insertion portion 65, and the side 67 of the protrusion is cut off, and a portion constituting the protrusion 55 is separated from the front member 59. The upper edge 69a and the supporting edge 69b corresponding to the base of the triangle are not separated.
In the constituent members of the separated projection 55, the supporting edge 63 is bent along the upper edge 61 to form a side surface 64 of the projection. In addition, the upper edge and the supporting edges 69 a and 69 b formed as a bent line located at the bottom of the upper edge 61 are appropriately bent to form the projection upper surface 66.
The insertion portion 65 located at the tip of the projection side surface 64 is inserted into the receiving portion 52 of the back member 57. The angle α ′ formed by the contact between the two insertion portions 65 is the same as the angle α formed by the tip of the upper edge 61. Therefore, the angle α ′ is equal to the angle β of the tip of the receiving portion 52, and the insertion portion 65 inserted into the receiving portion 52 is stably held (without twisting or shrinking). Is done. Thereby, the projection side surface 64 of the projection 55 is stabilized, and the projection 55 is formed on the bottom wall 50.
[0022]
FIG. 5 shows a state in which the packaging box 1 in which the above-described opening 13 and the projection 55 are formed is installed with the bottom wall 50 facing downward. FIG. 5 shows the first end wall 10 provided with the opening 13 on the left side.
As described above, since the distance between the support edge 63 and the upper edge 61 is gradually increased toward the second end wall 40, the upper surface 66 of the protrusion is higher on the second end wall 40 side. Even when the packaging box 1 is inclined with respect to the installation surface 7, a part of the upper surface 66 of the projection is arranged substantially parallel to the installation surface 7 due to the weight of the cylindrical container. Becomes possible.
[0023]
When the user takes out the cylindrical container 3 located at the head on the opening 13 side, the cylindrical container 3 ′ located behind the container is moved toward the opening 13 according to gravity due to the inclination γ of the bottom surface 50. Roll and move. The stopper 17 in the opening 13 abuts on the upper side of the cylindrical container 3, and the rolling movement thereof is suppressed, so that the cylindrical container 3 is prevented from being continuously discharged from the opening 13. Is done.
A part of the end surface (bottom surface or lid surface) 6 of the cylindrical container 3 appears on the user side by a side perforation 88 provided on the side surface of the opening 13. The user can easily remove the cylindrical container 3 by gripping the upper and lower end surfaces 6 thereof.
[0024]
The packaging box 1 is inclined by an angle γ with respect to the installation surface 7 because the protrusion 55 contacts the installation surface 7. The value of the inclination γ of the packaging box is appropriately determined according to the strength of the cardboard and the weight of the cylindrical container 3 to be stored. If the inclination γ is too large, the protrusion 55 will be crushed by the weight of the cylindrical container 3. On the other hand, if the inclination γ is too small, the disadvantage that the cylindrical container 3 does not roll into the opening 13 tends to occur. Thus, in the case of the packaging box 1 for 250 ml or 350 ml, the value of the inclination γ is desirably about 1 ° to 5 °, and the range of 1 ° to 3 ° is optimal. Alternatively, the height H5 of the protrusion 55 is preferably about 4 mm to 20 mm, and more preferably about 4 mm to 10 mm.
[0025]
In a desirable configuration of the present invention, a handle hole for facilitating the carrying of the packaging box is provided on the bottom surface. FIG. 4 shows the handle hole 31. In this embodiment, the handle hole 31 is provided so as to penetrate the front member 59 and the back member 57.
The handle hole 31 is provided substantially symmetrically on both sides of the center line 60. The front member 59 has a left handle hole 33a and a right handle hole 35a, and the back member 57 has a left handle hole 33b and a right handle hole 35b. These holes 33 and 35 have the same shape and are arranged at the same position when the front member 59 and the back member 57 are overlapped. Desirable size S of handle hole 31 is large enough to insert four fingers from the index finger to the little finger of the user, and specifically, is preferably about 6 cm to 9 cm. However, when the number of cylindrical containers to be packed is small, a finger hole type having a structure having one or two circular holes may be used.
Thus, by providing the handle hole 31 on the bottom surface of the double structure, it is possible to form the strong handle hole 31 without special reinforcement.
The left handle hole 33 and the right handle hole 35 do not need to have the same shape and size, and may be set appropriately according to the use of the packaging box 1.
