Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a container for accommodating a roll-shaped aluminum box or wrap film, which is generally used for simple packaging of food.

[Conventional technology]

Conventionally, roll-shaped aluminum foil or wrap film has been used for simple home packaging.

These roll sheets are mainly sold by being stored in a horizontally long paper box after being subjected to predetermined folding lines on a single carton blank and being manufactured according to the folding lines.

At the time of use, the opening zipper is removed, the end of the roll sheet is pulled out, and the necessary width is cut with a sawtooth to package food (Actual No. Sho 63-166921, No. 154432, JP-A-63-2726).
No. 56).

[Problems to be solved by the device]

However, in various commercially available roll sheet storage containers, cutting of the sheet has become extremely easy, but after removing the opening zipper, the opening / closing lid opens halfway every time the sheet is repeatedly taken out. The lid will not close completely when left standing, and dust, dirt, and
It was not desirable for hygiene because the pests invaded.

In addition, Japanese Utility Model Publication No. 52-35219 has been proposed as a structure for temporarily closing and closing the lid after opening, but the locking pieces formed on the upper edges of both sides of the container body project from both sides of the lid. For this reason, a plurality of them are packed together in a cardboard box for transportation, or when stacked at a store, the locking piece is damaged due to rough handling at home and the original temporary locking function cannot be exerted. There was room for improvement in points.

Further, there is also known a locking structure in which locking pieces formed on the container body are locked at both inner corners of the lid so as not to project from both side surfaces of the lid, but generally, when a carton blank is manufactured, it is folded and folded. Swelling portion R of the
(See Fig. (B)) As a result of the tips of the locking pieces formed on both sides of the container body hitting the raised portions and locking, the locking pieces are distorted or damaged and the original locking function cannot be exerted. However, there are inherent problems such as unstable locking.

[Means for Solving the Problems]

The purpose of the present invention is to secure and stabilize the temporary locking of the lid at the time of reclosing as described above. Specifically, a crease is formed on the upper edge of the back plate of the container body. In a roll sheet storage container in which a lid that covers the opening of the container body is connected in a freely openable and closable manner, in the front plate side edges of the container body, or the front edges of the lid body at the front edge parts of the left and right side plates. The locking creases (9) are formed by extending locking protrusions for locking with the inner corners of the lid and removing the raised portions of the creases formed at the inner corners on both front sides of the lid B. A roll sheet storage container characterized in that a locking projection (10) is locked and a lid is closed.

[Action]

When the end of the roll sheet is pulled out and the necessary width is cut with saw teeth and the lid B is closed, the locking creases 9 which are the inner corners on both front sides of the right-angled lid B without the raised portion R, The locking projections 10 extending to the container body A are brought into contact with each other and locked, so that there is no collision with the raised portion due to the crease.

〔Constitution〕

Hereinafter, the present invention will be described in detail with reference to the drawings, which are one embodiment.

FIG. 1 is a development view of a roll sheet storage container according to the present invention. In a container body A, a folding plate 7, a front plate 1, a bottom plate 2 and a back plate 3 are sequentially arranged in sequence through folding lines. Adhesive flaps 11, 11 are continuously provided on both sides of the front plate 1 via folding lines, and locking projections 10, 10 projecting to the adhesive flap 11 side are provided above both sides of the front plate 1. Both side edges of the front plate 1 are extended and formed by cutting. Side plates 12 and 12 are provided on both sides of the bottom plate 2, and inner plates 13 and 13 are provided on both sides of the back plate 3, respectively, via folding lines.

On the other hand, in the lid B, a lid top plate 4 and a lid front plate 5 are successively provided in this order on the back plate 3 via folding lines, and the lid front plate 5 is attached to the lid front plate 5 via a sewing machine wire or the like. 6 are arranged in a row.

Lid side plates 14 and 14 are provided on both sides of the lid top plate 4, and adhesive flaps 15 and 15 are provided on both sides of the lid front plate 5. The front lid plate 5 and the front attachment plate 6 are continuously provided via a perforated wire, but saw teeth are provided on the back surface of the front edge of the front lid plate 5, and the front attachment plate 6 is cut off. Then, the teeth of the sawtooth appear. In addition, an adhering portion half-cut into an oval shape is provided on the back surface of the adhering front plate 6 (not shown), and is partially adhered to the surface of the front plate 1 of the container body during box making.

According to the assembling procedure of the present invention having the above-mentioned developed structure, first, the folding piece 7 is folded inward and adhered, the upper edge of the front plate 1 is doubled, and the front plate 6 is attached by the oval-shaped adhering part. It is attached to the surface of the plate 1 to form a square tube.

Next, on both sides of the container body A, the adhesive flaps 11, 11,
When the inner plates 13, 13 and the side plates 12, 12 are sequentially folded and attached, both sides of the container body A are assembled. Adhesive flap 11,
When the locking projections 10 and 10 are protruded to both sides due to the folding of 11, the inner plates 13 and the side plates 12 that are sequentially folded are overlapped on the adhesive flap 11, so even if they are overlapped, they are left and right. It is necessary to cut and form the locking projection 10 so that the stop projection 10 projects. Further, since the upper edge of the front plate 1 of the container body A is reinforced by the folding of the folding piece 7, the locking projections 10 protruding in the left-right direction of the front plate 1 exhibit a stable locking function. The locking protrusion 10 may be provided at the front edge of the left and right side plates 12, and in this case, the side plate is the outermost surface, and therefore the above consideration is not necessary.

Next, the procedure for assembling the lid B continuously provided on the upper edge of the back plate 3 of the container main body A is as follows. When it is attached to the back surface of 14, it becomes a cover that covers the opening of the container body A. By the way, when the lid side plate 14 and the sticking flap 15 are stuck together, conventionally, as shown in FIG. 3 (b), a raised portion R is generated at the inner corner of the sticking flap 15 due to a crease. Since the folding creases (9) which are the right-angled corners in which the raised portion R is removed are formed by applying a sewing line or embossing on the folding creases at the inner corners, the locking protrusions are exactly at the inner corners. 10 will come into contact and be locked.

Further, the front plate 1 for sticking, which is connected to the front plate 4 for the lid through the perforations, is stuck to the front plate 1 to complete the container of the present invention. The roll sheet S is appropriately loaded when the present invention is in the rectangular tube state or after the container body A is assembled.

〔effect〕

Since there is no raised portion R due to the creases in the inner corners on both front sides of the lid B of the present invention, the locking projection is not damaged and the locking mechanism is not deteriorated. Since it does not protrude from both left and right sides of the lid, mass transportation and stacking at stores,
Even if it is handled roughly at home, the locking projections will not be damaged or distorted, the lid re-closing will be reliable and stable, and the ingress of dust, dust, insects from the outside It is a container that is preventable, hygienic, and highly practical. Further, since the locking projection is simply formed by cutting as the locking structure, the existing equipment can be used as it is, and the manufacturing cost can be reduced without using an extra packaging material.
