JP2003128053A - Knockdown corrugated cardboard-made packing box - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the possibility of a metal fitting or a wide-width sticking tape, used as a fixing tool to fix the upper surface of a box, falling into the contents therein or causing injury, when taking them out, in the case of the former, or very much covering a printed indication surface blocking it from achieving its purpose, in the case of the latter, in a corrugated cardboard-made packing box to be used for packing and transporting commodities, etc., which has an aperture provided on the upper surface thereof for verifying the commodities housed therein (the contents). SOLUTION: In the conventional manner, there is a portion, on an upper surface, where flaps are overlapped, necessitating use of a fixing tool to fix them. In order to solve the challenge of dispensing completely with the fixing tool used on the upper surface, a corrugated cardboard-made packing box with the following specification is provided. In a knockdown corrugated cardboard-made packing box that is evolved around in four side surfaces installed in communication in the form of enclosing the bottom surface, the box is formed in such a way that a large aperture is provided on the bottom surface thereof, leaving suitable frames, so as to verify the commodities housed therein (the contents), and the box is turned upside down for use, thus providing a knockdown corrugated cardboard-made packing box which requires no fixing tools at all on its upper surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard packing box.

[0002]

2. Description of the Related Art In the food distribution industry, one of cardboard packaging boxes used as an outer container for packaging and transporting products is provided with a large opening leaving a suitable edge on the top of the box for quality confirmation or Some items (contents) are used as windows for approval.

Conventionally, the above cardboard packing box has flaps a10 to d10 and a20 to d20, which are connected to the upper and lower ends of the four side surfaces a, b, c and d, as shown in the exploded view of FIG. And a glue margin piece e connected to the side of a,
Fold through the fold line 10, connect the adhesive margin piece e and the side surface d, and fold the flap b20 through the fold line 30, and similarly fold the flaps d20, a20, c20 and the fold flaps a20 and c20.
When the side where the edges of the flap are butted is stopped and closed by a stopper, the flap b10 is folded along the fold line 20 and similarly folded with the flaps d10, a10, c10, and the overlapping portion of the flap is stopped with the stopper. This is a cardboard packaging box having an upper surface composed of an opening and an edge in the plan view shown in FIG.

[0004]

Conventionally, the above-mentioned cardboard packaging boxes have sufficiently met the needs of the industry, but in terms of food hygiene, display printing of stored items (contents), from the industry. The demands of the above are becoming stricter and it is desired to improve.

[0005]

The use of a stopper is indispensable in order to fix the edge of the upper surface of the cardboard box of the above-mentioned type. It has been pointed out that this stopper may be mixed in the stored contents (contents) at the time of taking out the product, or may obscure the display printed matter.

The present invention has been made for the purpose of solving the above problems. The metal fitting shown in FIG. 5, which is used as a stopper on the upper surface of this cardboard packing box, has a wide adhesive. By eliminating the use of tape etc. at all, we will provide a prefabricated cardboard packaging box that has an edge on the top and a large opening for confirming the contents (contents), which has decided to solve the above problems It is in.

[0007]

In order to achieve the above-mentioned object, a cardboard-made packaging box according to the present invention has been conventionally used.

In the hexahedron-type corrugated cardboard packing box that is developed on four sides that are continuously connected in a manner surrounding the bottom surface instead of the method described in [1], an appropriate edge is provided on the bottom surface to confirm the contents (contents). A large opening is left and formed.

[0008] Furthermore, a pair of opposite side surfaces is provided with a flap, which is a plug-in type and a lock-type type in the other side, to stop the diameter of the box so as to facilitate the storage of the product and to close it with a wide adhesive tape when the storage is completed. Use the box inverted.

When the box is manufactured as described above, the upper surface of the box is formed without applying a stopper, and the stopper is mixed with the contents (contents) of the stopper or the printed display object is covered. Can be stopped.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 is a development view applied to an embodiment of the present invention.

The surface A, which is originally the bottom surface, is taken out to leave an edge A1 for the purpose of preventing the contents (contents) from being removed in order to take an opening Z for accommodating the contents (contents). The side surfaces of the cardboard box are B, C, D, and E, which are connected to A, and the flaps B1, C1, D1, which are opening / closing portions on the side surfaces.
E1 is installed in series. Further, on the side surfaces B and D, flaps B2, B3, D2 and D3 processed for the purpose of temporarily combining the shape of the box with the opening / closing portion open are provided.

When assembling the cardboard box, the flaps B2 and D2 and B3 and D3 can be combined by folding B and D through the folding line 1 and then B2, B3, D2 and D3 through 2 to store the stored items. The shape of the box that enables the storage of (contents) will be shaped. In the following, if you fold C and E through fold line 3 and C1 and E1 through 4, the inner flap C
1, E1 covers the combination flaps B2D2, B3D3, and folds B1, D1 along the folding line 5, and the outer flaps B1, D
The area where B1 and D1 where 1 overlaps on the inner flap is abutted and stopped with a wide adhesive tape, and the whole box is inverted. As a result, it is possible to provide an assembling-type cardboard packaging box having an opening for accommodating the contents (contents) without using any fasteners on the upper surface.

[0013]

Since the prefabricated cardboard packaging box according to the present invention is prefabricated, it helps reduce the work space for prefabricated products.
In addition, it does not require the use of tools at the time of manufacturing and can be assembled simply, so it has a good workability and has the effect of speeding up manufacturing.

The use of metal fittings for the fastener is reduced to zero, and the amount of adhesive tape or the like is also reduced, resulting in cost reduction.

Accidents such as the inclusion of foreign objects such as metal fittings, which often occur when taking out stored items (contents), because no printed parts can be read clearly because no stoppers are used on the upper surface, and no unsightly appearance is shown on tape. The effect of blocking is obtained.

At the time of unpacking the cardboard packing box, taking out the stored contents (contents), or disassembling, the fear of injury due to the metal stopper is eliminated, and the safety is further enhanced. Also, from the perspective of recycling, it is possible to suppress reuse costs by not mixing foreign matter, and to expect better recycling for the global environment.
