Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a roll sheet storage container in which resin sheets, aluminum foil sheets, etc. are wound around a roll core.

(Prior Art) Various devices have been devised in the past to store roll sheets in an attractive manner and to prevent the rolls from flying out of the container when the sheets are pulled out during use.

For example, the locking effect on the storage rolls should be made sufficient, and the locking force on the rolls should be improved to prevent the rolls from being pulled out inadvertently even if a certain amount of tension is applied, and the locking force on the rolls should be improved. A method described in Japanese Utility Model Publication No. 16500/1983 devised by the present inventors is known for the purpose of improving the rotatability of the roll.

In addition, in order to improve the strength of the storage container, the container is designed so that the rolled-up sheet-like material stored inside can be unrolled to an appropriate length through a slit in the width direction, and the container body and lid are made of synthetic resin. are connected by a hinge so that they can be opened and closed, and a slit is formed on the side edge opposite to the hinge, and the slit formed between the container body and the lid body has a gap in the normal state. The containers are brought into contact by pressing, and the container body is provided with a cutting blade along the opening edge, and the lid body is provided with a cutout for drawing out a sheet-like object approximately at the center of the opening edge. A structure having the same configuration is also known from Japanese Utility Model Publication No. 55-5473.

(Problems to be solved with the invention) However, since the former container is constructed by folding a cardboard carton to form a rectangular container, it has poor durability, shape retention, and water resistance, and is particularly difficult to reuse by refilling the roll sheet. It was unbearable to use.

In addition, in the latter synthetic resin container, it is necessary to attach a metal cutting blade to the opening edge, which not only increases the number of manufacturing steps, lowers production efficiency, and increases costs. Even if the metal cutting edge is configured to be wider than the gripping piece on the container body side and protrude outward, the metal cutting edge described above has to protrude outward from the gripping piece on the container body side, making it difficult to handle. It is easy to touch the cutting blade when cutting, and since the engagement pieces with the container body that extend downward from the lid body are only on both left and right edges of the lid side clamping piece, the engagement tends to come off relatively easily. In addition, there were also problems in terms of safety, such as operational hazards.

(Means for solving the problems) The present invention solves the problems of the prior art described above,
It is designed to improve the durability and shape retention of the container, as well as improve productivity and safety. Specifically, it is designed to improve the durability and shape retention of the container, as well as improve productivity and safety. In a storage container that is integrally constructed with a lid that is connected to the container and can be opened and closed using a synthetic resin material, the flange extends horizontally outward from the opening of the main body of the container, and the front edge of the flange has a serrated shape. The edges of the lid body are bent downward at a substantially right angle when the lid is closed to form an edge cover and a side cover, and at least a portion of both covers is provided with the edge edge and/or a flange. The present invention relates to a rolled sheet storage container formed with an engaging part that projects inward to engage with the leading edge of the rolled sheet container.

(Structure) The specific contents of this invention are explained below in Parts 1 to 3.
An explanation will be given based on an embodiment shown in the drawings. Reference numeral 1 denotes a long container body, and 3 denotes a lid body connected to the back side of the opening of the container body 1 so as to be openable and closable.

The container body 1 has a front side flange 2a, a back side flange 2c, and left and right side flanges 2d extending horizontally outward at its opening, and furthermore, the front flange 2a has a front flange 2a that extends horizontally outward. A serrated edger 2b is formed with the cutting edge exposed, and the tip edge of the rear flange 2c is folded upward and connected to the lid 3. The lid body 3 has an area on each flange of the container body 1 that can be overlapped, and the end portion corresponding to the edger 2b provided at the tip edge of the front side flange 2a of the container body 1 is connected to the lid. The edger cover 4 is formed by bending the edger cover 4 downward at a substantially right angle, and at least a portion of the edger cover 4 is formed with an engaging portion 5 that protrudes inward to engage with the edger 2b. Also, the left and right side flanges 2 of the lid body 3, that is, the left and right side flanges of the container body 1.
At the end corresponding to the tip edge of d, a side cover 6 is provided in connection with the edger cover 4, and an engaging portion 5a that can be engaged with the tip edge of the left and right side flanges 2d is provided.

Note that the side cover 6 and the engaging portion 5a may be omitted if the purpose is only to lock the lid.
When this is provided, not only can the strength of the edger cover 4 described above be further improved, but also the engagement can be made more secure, and the intrusion of dust, dirt, insects, etc. from the outside can be prevented. is valid.

Further, both the engaging portions 5 and 5a may be provided,
Alternatively, it may be limited to either one.

In the figure, 1a indicates a holding portion for stably placing the container body 1 on a flat surface, and 1b indicates a stopper support portion protruding toward the inner surface of the container body 1 on the left and right side surfaces.

The container main body 1 having the above-mentioned holding part 1a, stopper support part 1b, and flanges 2a to 2d, and the lid body 3 having the edger cover 4, side cover 6, and engaging parts 5, 5a are made of plastic or other materials. The resin material is simultaneously molded by melt-cutting or other means.

Reference numeral 7 designates a rectangular band-shaped base member made of a cardboard carton and superimposed on each flange 2a, 2c, 2d with only the serrated edges 2b of the container body 1 slightly exposed; Tongue pieces 8 each having a substantially semi-circular tip end are arranged inwardly from the inner edges of the left and right ends of the member 7 in the longitudinal direction.

The base member 7 is adhered to the upper surface of each of the flanges 2a, 2c, and 2d of the container body 1 using an adhesive or the like, and the tongue pieces 8 on both left and right ends are attached to the container body 1.
Bend it toward the inner bottom of the

Note that if the stopper support portion 1b itself is a protruding portion that locks onto the roll core, the base member 7, tongue piece 8, etc. are unnecessary.

(Function) In the configuration of the embodiment described above, the rolled sheet R is charged into the container body 1 with the upper lid 3 open.

At this time, the tongue pieces 8, 8 are pushed and bent toward the bottom of the container main body by both ends of the roll sheet R in the longitudinal direction (left and right directions), and the tip of the tongue pieces 8 is bent into a semicircular arc shape at the position where the roll sheet R is approximately stored in the container main body. The tongues 8, 8 enter into the inner peripheral side of the roll core, and the back sides of the tongues 8, 8 come into contact with the stopper support part 1b projected inside the container body 1 to prevent the roll sheet from slipping out.

Furthermore, when the lid 3 is closed to the container body 1, the upper part of the edger cover 4 is pressed downward against the reaction force of the continuous bending part, and the engaging part 5 is pressed against the bottom surface of the edger 2b. It is possible to engage and completely envelop the edger 2b.

In addition, when the engaging part 5 is not provided on the edge cover 4, the engaging part 5a of the side cover is used for engagement.

Also, when replacing the roll sheet R, the tongue piece 8,
After removing the tip of No. 8 from the roll core and taking it out, another roll sheet is inserted and replaced.

Note that when the container body and lid are integrally molded from transparent resin, the remaining amount of the roll sheet can be visually confirmed.

(Effects of the invention) As described above, the present invention extends the flange horizontally outward from the opening of the container main body, integrally forms a serrated edge on the tip edge of the flange on the front side, and furthermore When the lid is closed, the edge portions are bent downward to form a substantially right angle to form an edger cover, a side cover, and an engaging portion that protrudes inward to engage at least a portion of both covers with the edge of the edger and the flange portion. Because of this, the edger is not touched when handling the storage container, making it extremely safe, preventing dirt and insects from entering the container, and also preventing the holding part, stopper support, each flange, edger, etc. Since the container main body having the above-mentioned shape, the edge cover, the side cover, and the lid body having the engaging portion can be integrally fabricated from plastic or other synthetic resin materials, the manufacturing process can be omitted and productivity can be improved. However, it has various beneficial effects such as significantly improving durability and strength, improving economic efficiency by enabling repeated use, and reducing costs.
