Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a subdivided corrugated cardboard box and a paper box suitable for use as an outer box packed with a plurality of canned drinks such as soft drinks and beers, and a plurality of paper packs and plastic bottles of juice and tea.
[0002]
[Prior art]
In recent years, canned beverages, bottled beverages, and the like are often packaged in six or twelve shrink packs or multi-pack paper boxes and sold at retail stores. On the other hand, in the transportation from a wholesaler to a retail store, distribution using cardboard boxes containing 20 bottles and 2 dozen is also performed as before.
There is also known a packaging form in which a plurality of small boxes made of cardboard or paperboard are connected and transported and stored as one box in an intermediate form.
For example, as disclosed in Patent Document 1 and the like, a packaging box that can be divided as necessary has been proposed. According to such a packaging box, a plurality of packaging boxes are connected at the distribution stage and divided at the end stage of distribution, thereby meeting the two purposes of streamlining distribution and responding to various needs. Will be.
[0003]
However, in the conventional split-type packaging box, the bonding between the common lid and the plurality of boxes is partial when viewed from the entire box, and the bottom is not connected. Then, there is a problem that wobbling occurs between the plurality of small boxes during transportation, a force is applied to the bonding portion of the common lid, the bonding is released, and the upper sealing property of the box is impaired (see FIG. 7).
In order to prevent this, the sides adjacent to each other of the individual trays may be fixed by hot melt or a plurality of trays may be separately fixed with a tape (30) (see FIG. 6), but the manufacturing process becomes complicated. This is a factor that lowers productivity.
[0004]
Patent Literature 2 or Patent Literature 3 proposes to use the partial projections of the mutual trays for fixing in order to solve such a drawback, but is effective for wobbling of the mutual trays. However, the shape of the tray after subdivision was distorted, and the aesthetic appearance of the tray was lacking.

(1) A plurality of upper open tray-shaped small boxes arranged in a row, a top plate for closing the open upper part of the small box, and an upper side flap extending to the side from the top plate and connecting the plurality of small boxes. The upper side flap has an extension protruding downward before and after the small box connecting portion in the collective packaging box connected by the common lid having:
(2) In the invention of the above (1), a collective packaging box in which a tip end of the upper side flap extension portion projects at least half the height direction of the side surface.
(3) A packaged article according to (1) or (2), wherein after packing and packaging the article in the packaging box according to (1) or (2), in a distribution process, the common lid top plate is transported with the surface of the top side down. Transportation method.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
The small box and common lid used in the present invention may be made of cardboard or paperboard. Microflute cardboard may be used.
Hereinafter, the shape of the box will be described with reference to the drawings as necessary.
[0009]
The form of the upper open tray-shaped small box in the present invention may be any. In addition, the format and direction of a line are not particularly limited. However, in order to prevent waste of blanks and to consider the balance of box strength, the form and connection direction of the small box as shown in FIG. 1 or 8 are preferable.
That is, the small box has a square bottom surface and a wife surface (2) rising from a pair of opposite sides of the bottom surface, a lateral side flap (3) connected to the side of the wife surface to form an inner side surface of the box, and a bottom surface facing the bottom surface. A preferred form is a small box formed from a lower side flap (4) that rises from another pair of sides and forms part of the outer side. The remaining portion of the outer side surface of the box is formed by an upper side flap (7) extending from the lid. In this case, the connection directions of the small boxes are such that the wife faces of the small boxes are in contact with each other. Further, it is preferable that there are two small boxes from the viewpoint of handling and strength balance.
[0010]
Although the upper part of the small box is open, a small upper flap (9) may be extended from the wife's face or the side face. If necessary, the upper flap (9) and the common lid are bonded with an adhesive. Is also good.
[0011]
A common lid according to the present invention includes a top plate (1) that closes an open upper portion and an upper side flap (7) that extends from the top plate to the side and connects a plurality of small boxes (20, 21). Any shape may be used as long as it is a lid. However, in consideration of box strength, sealability, and appearance, it is preferable that the lower end line (71) of the upper side flap abut the upper end line (41) of the lower side flap.
[0012]
Further, the present invention is characterized in that the upper side flap has an extended portion (8) protruding before and after the connecting portion (30) of the small box.
It is preferable in terms of appearance and strength that the lower side flap tip (51) corresponding to the lower tip line (81) of the extension portion also abut.
In the illustrated drawings, the extension portion (8) is trapezoidal, but may be a triangular shape, a semicircle, a quadrangle, or the like.
[0013]
The dimensions of the extension will be described with reference to FIG. When the width of the side surface is A and the width of the base of the extension is B, the value of B / A is preferably １ ／ to １ ／ in terms of strength and design.
When the distance between the tip line (71) other than the extension of the upper side flap and the top surface is C, and the length from the top surface to the tip of the extension portion is D, C is 1/3 of the side height H. D is preferably in the range of 2/3, and D is preferably in the range of 1/2 to 1/1 of H. In particular, it is most preferable in terms of strength that D is substantially equal to H (the end of the extension reaches near the bottom of the box).
[0014]
The common lid is perforated (6) so that a plurality of small boxes can be divided. The perforations are continuously applied to the upper side flap and its extension.
[0015]
The common lid may be a separate lid as illustrated in FIG. 8, or may extend from the wedge face of one small box as illustrated in FIG.
[0016]
The common lid usually fills each box with the contents and then applies an adhesive to the top or side flaps and immediately joins the top and side flaps. The adhesive may be any of a solvent-based adhesive, a water-based adhesive, and a hot-melt adhesive, but a hot-melt adhesive is most preferable from the viewpoint of workability.
[0017]
Since the collective packaging box of the present invention is bonded to a plurality of small boxes in a shape having high strength, the small boxes (20, 21) do not fluctuate even when transported with the bottom side down. However, when the common lid is placed on the lower side and transported in the form as shown in FIG. 4, one bottom plate becomes the lower surface during transport, so that the bottom portion is connected when the conveyor is transported or the boxes are manually transported. There is little risk of damage from the part.
[0018]
【Example】
FIG. 1 shows an embodiment of the present invention.
This drawing is an example in which a common lid is formed by extending from one of two wives of two trays, and is an example in which two small boxes are connected.
FIG. 11 and FIG. 12 are development views of each member.
This case material was made of cardboard. However, not only cardboard but also materials such as paperboard can be put to practical use with the same idea. These two trays are filled with canned beverages and the like by a special filling machine and sealed beverage containers are filled in a specified quantity, and then hot melt adhesive is sprayed onto the parts that come into contact with the common lid part of the trays, and pressure rolls etc. Seal and fix with.
This makes it possible to seal the case as shown in FIG.
[0019]
FIG. 3 shows a state in which one side of the container of the present invention is divided and opened for subdivision.
A perforation for division is provided in the center of the common lid in advance, and by pulling the perforation, subdivision into two trays is possible.
The basic method of opening each container after subdividing is to peel off the flap by hand, but this does not refuse auxiliary agents such as labels.
As is well known, when the flap is once opened and then resealed, the flap is generally inserted into the carton.
FIG. 8 shows another embodiment of the present invention.
In this case, it is composed of two trays of substantially the same shape except for the cut shape of the bottom flap and three members of a common lid. After tightening the lid with the same idea as in FIG. 1, the case becomes strong.
The state at the time of subdivision separation is substantially the same as that of FIG.
[0020]
FIG. 4 shows a connection case in which the common lid of the connection tray of the present invention is formed at the bottom and hand holes are formed in advance. In this state, the common lid becomes a firm bottom and is in a very stable state even when the beverage or the like is filled and sealed.
When subdividing, it can be opened without any problem by turning it over and opening it from the perforation with the common lid facing up.
[0021]
【The invention's effect】
As described above, in the present invention, a plurality of packaging boxes are closed with a common lid plate, and upper side flaps provided on both sides of the lid plate, and the upper side flaps are further lowered before and after the connecting portion. Since the projecting extension is provided, there is an advantage that the adhesive strength is high and the bottom does not fluctuate during transportation.
In a preferred embodiment, the upper side flaps and the lower side flaps extending from the bottom are brought together and connected, and each packaging box independently has a rectangular parallelepiped shape. Since the packaging boxes are maintained, when divided, the packaging boxes after the division independently function sufficiently as packaging boxes and exhibit sufficient strength.
Further, the split packaging box of the present invention is adapted to be glued or adhered on the outer surface of the side wall orthogonal to the side plates overlapping each other. Therefore, the strength of such side wall portions is increased, and a packaging box having high buckling strength is obtained.
In addition, the packaging box according to the present invention can be used as a display display case by cosmetically printing on both sides like a normal candy container.
Even after the logistics stage is completed, even if it is divided into two pieces, the display case can be used to display and sell the goods as contents by such a display case.
