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 ideas have been made 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, there is a paper container described in Utility Model Application Publication No. 50-97824 which has half-moon-shaped tongues on both longitudinal ends of the container so that they can enter into the core of the rolled film. However, the locking effect on the storage roll is not sufficient, and if a tensile force beyond a certain level is applied, there is a risk that the roll will be pulled out inadvertently. He completed a device aimed at improving the locking force of the rolls and the rotational performance of the rolls inside the container (Utility Model Publication No. 16500/1983). Also, Jikaisho invented the idea of molding the container body with synthetic resin.
No. 52-42131, Jitko No. 55-5473, Jitko No. 56-
No. 48055 etc. are known.

(Problems to be solved by the invention) However, most of the above-mentioned inventions are made by folding a cardboard carton to form a rectangular container. It was not possible to reuse the sheet by refilling it. In addition, with synthetic resin containers, it takes time to insert the rolls, and the use of hard synthetic resin materials increases manufacturing costs.Furthermore, the rolls do not rotate well within the container, and the sheet There were problems such as difficulty in checking the remaining amount.

(Means for solving the problem) Therefore, in the present invention, the container body is integrally molded from plastic or other synthetic resin material to improve durability, shape retention, and water resistance, and to improve the durability, shape retention, and water resistance of the container body. It is designed to improve rotationability and prevent the roll from slipping out. Specifically, it is formed into a semi-cylindrical shape from the side to the bottom, the top is open, and the peripheral edge of the open end is a synthetic resin container body formed with a flange extending outward in a horizontal radial direction;
It consists of an opening/closing lid made of the same or different material as the container body, which is attached to the flange of the container body and closes the opening, and the container body has at least a pair of left and right stands with a part of the bottom flattened. and a pair of left and right protrusions corresponding to the length of the roll core protruding inward at both ends in the longitudinal direction of the container body, and the opening/closing lid body has a pair of protrusions that overlap on the flanges of the container body described above. A pair of locking tongues that can be bent are arranged in a row from the left and right edges to be attached downwardly inside the opening of the container main body via the fold line, and when the roll is inserted, the tips of the locking tongues are attached to the roll. The present invention relates to a rolled sheet storage container configured to be located within the core.

(Example) The specific content of the present invention will be explained below based on an illustrated example. 1 is a container body made of synthetic resin, and 10 is a material made of the same material as the container body or preferably a different material such as carton paper. The opening/closing lid body is shown. The container body 1 is formed into a semi-cylindrical shape from the side surface 2 to the bottom surface 3, and has an open top surface, and is further provided with a flange 6 extending outward in the horizontal radial direction from the peripheral edge of the open end, and furthermore, a portion of the bottom surface 3 is made flat. A pair of left and right stand parts 4, 4, arcuate ribs 5 projecting inwardly or outwardly from the semi-cylindrical surface at multiple locations in the longitudinal direction, and left and right stands formed at both ends of the container body 1 in the longitudinal direction. An extension of the arch-shaped rib 5 formed in the semi-cylindrical part, which is the part between the pair of protrusions 7, 7 which protrude inwardly of the container, and the joint between the side surface 2 of the container body 1 and the opening flange 6. shape-retaining ribs 9 that partially bulge out to the outside where the ribs are formed;
In addition, the pair of protrusions 7, 7 gradually increase in protrusion from the bottom of the container body 1 toward the upper opening, form an inclined portion 8 toward the upper opening, and form an inclined portion 8 toward the inside of the container body 1. They are formed to protrude toward the side and face each other at intervals corresponding to the length of the roll core. It is preferable for the arcuate ribs 5 to protrude inward from the viewpoint of roll rotation, but in the case of a roll sheet of aluminum foil, the surface of the aluminum roll is pressed by the inward arcuate ribs 5. , it will lead to a decline in the product price, so it should be projected outward as necessary.

The material of the container body 1 can be easily obtained by vacuum forming polyethylene, polystyrene, polypropylene, polyethylene terephthalate, or other synthetic resin materials, and the formed container body 1 is preferably transparent or translucent. good.

On the other hand, the opening/closing lid body 10 is made of carton paper having a size approximately equal to the area of the flange 6 of the container body 1 described above, and is made up of an upper plate 10a and a lower plate 10b that are folded in half along the fold line a. , the lower plate 10b is bent downward into the opening of the container body 1 from a portion corresponding to the flange 6 on the opening edge of the container body 1 and from both left and right end edges overlapped and adhered onto the flange 6 via the fold line 10e. A window portion 10c is formed in line with the opening of the container main body, leaving a pair of locking tongues 10f, 10f that can be connected to each other, and the upper surface of the lower plate 10b on the opposite side (front side) of the fold line a is provided with saw teeth. A shaped cutting tooth 12 is attached. Auxiliary pieces or stepped portions are provided on both sides of the locking tongue 10f to prevent the tongue from entering excessively.

Further, perforations 13, 13 are formed near both end edges in the left and right longitudinal direction of the upper plate 10a at positions corresponding to the cutting line of the window 10c of the lower plate 10b, and in this case, the front incisors 12 are formed on the upper plate 10a. A fold line b is made along the cut line of the opening edge, and the part in front of the fold line b is an insertion piece 10d, and the tip of the insertion piece is somewhat longer than the front protrusion of the incisor 12. It is more preferable to extend it in this way.
Further, if a notch is provided at the tip of the perforation line 13, it can be used as the opening start end of the upper plate 10a, which will be described later. Further, although not shown in the drawings, if a notch is formed in an arc shape in the direction of the upper plate 10a from both left and right ends of the base point with positions at regular intervals on the fold line b as a base point, the front side of the upper plate 10a along the fold line b is formed. When the end edge is bent at right angles, the portion surrounded by the notch rises upward to form a handle, making opening and closing of the top plate more convenient. Further, the upper plate 10a and the lower plate 10b are constructed by bonding adhesive parts 11, 11 to each other at both left and right ends in the longitudinal direction, and the opening/closing lid 10 is placed in the container body with the lower plate 10b facing downward. 1 by integrally attaching it to the upper end flange 6 of the device 1 with an adhesive (see FIG. 1). In this case, the rolled sheet is loaded into the container body 1 in advance or at the time when the lower plate 10b of the opening/closing lid 10 is fixed to the flange 6 of the container body, and in this case, both left and right ends of the rolled sheet are locked. Push the tongues 10f, 10f downward along the folding lines 10e, 10e, and slide the ends of the locking tongues 10f, 10f inside the roll core 15 while slidingly contacting both the left and right sides of the roll core 15. to enter.

(Function) In the configuration of the embodiment described above, when the portion of the insertion piece 10d on the front side of the upper plate 10a superimposed on the incisors 12 is pinched and pulled upward, the upper plate is positioned near both ends in the left and right longitudinal direction. The upper plate 10a is then torn along the perforation lines 13, 13, and the upper plate 10a is opened upward using the fold line a as a hinge. When the cutter is pulled out to a certain length, the part to be cut is pressed against the front edge of the incisor 12 and the cutter is used.

After the upper plate 10a is opened, the front insertion piece 10d is bent approximately at right angles along the fold line b, and is inserted into the container body 1 through the window 10c of the lower plate 10b to close the lid. When the stored roll sheet 14 is used up, the roll core 15 is removed and a new roll sheet 14 is loaded into the container body 1. In this case, the roll core 15 is guided by the sloped surface of the locking tongue 10f at both ends and can be easily pushed in. When the roll core 15 leaves the tip of the sloped surface, the roll core 15 is slightly bent due to the pushing of both ends of the roll core. The tongue pieces enter into the side openings of the roll core 15 due to the reaction, and the auxiliary pieces or stepped portions on both sides of the tongue pieces prevent the tongue pieces from entering excessively and reversing.
4 can be reliably locked in the container body 1. In this case, the protruding portion 7 acts to impart a certain inclination to the locking tongue piece 10f, prevent movement of the roll sheet in the longitudinal direction, and enhance the rotational properties of the roll sheet.

(Effects of the invention) As described above, in this invention, the container body is made of synthetic resin and is formed into a semi-cylindrical shape from the side to the bottom, and the stand part and the protruding part for locking the rolls are integrally molded. The rotatability of the roll within the container body is significantly improved.

In addition, the protrusions formed inwardly on both the left and right longitudinal end surfaces of the container body allow the locking tongues on the opening/closing lid side that protrude into the roll core to ensure that the tips of the tongues are always located within the roll core. Since it is supported reliably from the side, it not only further improves the rotatability of the roll described above, but also allows both ends of the roll to be reliably locked into the container body, and the protruding portion is attached to the opening/closing lid. Since the tongue piece on the body side is held in an oblique direction, it is possible to reliably prevent the roll sheet from flying out when being pulled out. Further, when both ends of the roll sheet pass over the tip of the locking tongue, the tip of the tongue makes a sound due to reaction, making it easy to confirm whether the roll is loaded.

Furthermore, the container body has good stability because it has at least a pair of left and right stands with a flat part of the bottom. Form retaining ribs are formed on the extension of each arcuate rib formed on the cylindrical part, which partially bulges out to the outside, significantly reinforcing the strength of the opening periphery. This allows for stable cutting of the film and also serves to reinforce the entire container. Furthermore, if the above-mentioned container body is made transparent or translucent, the remaining amount of roll sheet can be visually checked at all times, and only the roll sheet can be prepared in advance, which eliminates the inconvenience caused by the lack of roll sheet. .

The opening/closing lid body is made of carton paper, which is folded in half into an upper plate and a lower plate along the fold line, and an opening window is formed in the center of the lower plate, and the periphery of the opening window is attached to the container body. The upper plate and the lower plate are integrally adhered to each other on the flange, and the upper plate and the lower plate are integrally adhered to each other at both left and right longitudinal ends with adhesive, and perforations are provided somewhat inward from the adhesion position. Therefore, the top plate can be easily opened by simply grasping the front part of the top plate and pulling it upward.

Furthermore, when the top plate is opened, the perforations at both ends are separated, making it easy to detect unauthorized use and maintain quality assurance. Furthermore, carton paper has various beneficial effects such as good printing suitability, various designs, and easy differentiation from other products.
