Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage box for storing roll-shaped sheets such as paper towels, aluminum foil for cooking, and wrapping films for cooking with a core.

[0002]

[Prior art]

 According to Japanese Utility Model Laid-Open No. 60-15820, which is a conventional technique for this type of storage box, the top surface of the storage box is formed into an inner / outer double lid, a part of the inner lid is bent outward, and the bent piece and the outer A technique is disclosed in which a sheet is pulled out from between a lid and a cutter provided in a storage box and cut into a required length.

In Japanese Utility Model Publication No. 63-41335, one side of an outlet provided on the top surface of a storage box is bent outward, and a flap extending from one side is pressed onto the bent piece. However, there is disclosed a technique in which a sheet is pulled out from between the bent piece and the flap and is cut to a required length by a serrated cutting portion provided at a free end of the flap. On top of this flap is a flap extending from the remaining flanks so that the flap does not float up during use.

Japanese Utility Model Laid-Open No. 57-117302 discloses a structure in which a flap extending from the side surface of a storage box is provided with a support piece for rotatably supporting the stored roll-shaped sheet.

[0005]

[Problems to be solved by the device]

 Among the above-mentioned conventional techniques, in the technique disclosed in Japanese Utility Model Laid-Open No. 60-15820, if the sheet is pulled out while sliding between the inner and outer double lids, even if the remaining amount of the sheet decreases and the roll becomes lighter, The sliding resistance at that time does not cause the seat to be pulled out excessively, so that no waste occurs. However, in this known technique, the sliding resistance must be obtained by manually pressing the inner and outer double lids when pulling out the sheet, and it is difficult to always obtain a constant resistance when taking out the sheet. Also, children with small hands cannot request such pressing operations as adults.

On the other hand, in the technique disclosed in Japanese Utility Model Publication No. 63-41335, since the inner and outer double lids are held down by the flaps stacked on them, it becomes easy to obtain a constant sliding resistance when the sheet is pulled out. However, since the top surface of this storage box actually consists of four flaps and its structure is extremely complicated, it is difficult for the user to assemble the top surface, and more material is used on the top surface. However, there is a problem that it will be a factor to increase.

Furthermore, in both of these known techniques, when a sheet is pulled out, a roll-shaped sheet is rolled on the bottom surface of the storage box. Therefore, depending on the nature of the surface of the sheet, the frictional resistance with the bottom surface is large or small, resulting in smoothness. There is a problem that the amount of pulling out is not stable because it cannot be rolled. Another problem is that when the number of remaining sheets is low, the rolls start to dance in the storage box, and the amount of pullout is not stable.

By using the technique of Japanese Utility Model Laid-Open No. 57-117320, the roll can be stably rotated with the support piece provided in the storage box as the rotation axis.

In view of this, the present invention has a simple structure in which the top surface of the roll-shaped sheet storage box has an inner / outer double lid and the side flaps provided on the outer lid are engaged with the end surface of the storage box. The problem is to solve various problems.

[0010]

[Means for Solving the Problems]

 The points that this device uses as means for solving the above problems are as follows.

In this invention, each surface is composed of a tubular polyhedron and end surfaces that cover both ends of the polyhedron, and one of the polyhedrons is a top surface, and the top surface is composed of an inner lid and an outer lid. , The inner lid is provided with a sheet outlet and a tongue whose one side is bent outward of the polyhedron, while the outer lid covers the outlet and the free end of the tongue is provided. Since it can be pressed onto the sheet, the sheet sandwiched between the outer lid and the tongue can be pulled out, and the sheet cutting box provided on one of the multiple sides can cut the sheet to the required length. I have to.

On this premise, the end face is provided with a support piece that is bent inward of the polyhedron and rotatably supports the roll, and an engaging portion with an outer lid, and the outer lid has both side edges thereof. The side flap extending from the side is provided with an engaged portion that can be engaged with and disengaged from the engaging portion, and the degree of opening of the outer lid can be regulated by the engagement between the engaged portion and the engaging portion. That is the feature of this device.

In a preferred embodiment of the present invention, the outer lid has one side formed in a sawtooth shape, and the one side is bonded to an upper surface of the inner lid to form the cutting portion.

[0014]

[Action]

 In the storage box configured as described above, when the stored sheet is pulled out, the roll-shaped sheet smoothly rotates about the support piece. The tongue can be pressed against the outer lid whose opening is regulated, and the outer lid and the tongue act as a constant sliding resistance against the sheet pulled out from between them. , Suppress the momentum of pulling out the sheet. As a result, it is possible to accurately pull out the required amount of sheets even if the remaining amount of sheets becomes small and the roll becomes lighter, and it is possible to avoid wasting extra sheets.

【Example】

 The details of the roll-shaped sheet storage box according to the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a storage box 1 and a pulled-out state of a stored roll-shaped sheet 2, with a part thereof broken away. The storage box 1 is a folding box made of cardboard, and has a tubular tetrahedron 6 each having a rectangular top surface 3, a pair of side surfaces 4, and a bottom surface 5, and a pair of end surfaces 7 covering both ends of the tetrahedron 6. It is composed by. The top surface 3 includes an inner lid 11 fixed to the tetrahedron 6 and an openable / closable outer lid 12, and the inner lid 11 has a drawer opening 13 of the sheet 2 and an edge portion on the drawer side. A tongue-shaped piece 14 bent outward (forward) so as to draw a horizontal V shape together with the upper surface of the, and a serrated sheet cutting portion 16 provided along the ridge line 15A of the storage box on the drawer side. , And an end face wrap 11A extending from both sides. The outer lid 12 has a fixed end 20 adhered to the upper surface of the inner lid 11 along the ridgeline 15D of the tetrahedron 6, a free end 21 facing the fixed end 20, and a pair of side flaps 22 extending from both sides. However, the side flap 22 is provided with a later-described engaged portion 23.

The end face 7 is formed by folding an insertion portion 11 B, which will be described later, provided at the free end of the end face flap 11 A of the inner lid 11 along the bottom surface 5 inward of the tetrahedron 6. 1 has a slit 24 parallel to the upper surface thereof. Inside the end face 7, there are flaps 4A, 4B extending from the side edges of each side face 4 and having supporting pieces 25A, 25B, and these supporting pieces 25A, 25B are inside the tetrahedron 6. The roll-shaped sheet 2 is bent and inserted into the winding core 2A. Details of the insertion will be described later with reference to FIG.

FIG. 2 is an end view showing the relationship between the end face 7 and the side flap 22 by (A) and (B), in which the side flap 22 is in a state before being engaged. , (B) is after the engagement and the outer lid 12 is open. Further, in (B), the tongue piece 14 and the roll-shaped sheet 2 are shown by imaginary lines. The side flap 22 has a base line 27 that is inclined by an angle α with respect to the horizontal slit 24, and the engaged portion 23 is a semicircular small piece that is upward with respect to this base line, and is provided with a cut line 28. Is formed. The engaged portion 23 can be inserted into the slit 24 by slightly bending along the base line 27. However, if the tongue-shaped piece 14 of the inner lid is bent outward before insertion, the outer lid 12 is engaged by the force of the tongue-shaped piece 14 to return to the state before bending. When the portion 23 comes into contact with the upper edge of the slit 24 at the position of the base line 27, the roller can be opened (see FIG. (B)). The seat 2 is located between the outer lid 12 and the tongue 14 and is pressed against the outer lid 12 by the restoring force of the tongue 14, so that the seat 2 is always pulled out when the seat 2 is pulled out. A constant sliding resistance due to 14 acts.

FIG. 3 is a perspective view of an end surface showing a state in which the support pieces 25A and 25B are inserted to support the winding core 2A of the roll-shaped sheet 2 on the end surface 7. The flaps 4A, 4B extending from the pair of side faces 4 have a width of about 1/2 of the end face 7, and the supporting pieces 25A, 25B of each of these flaps are bent 90 ° inward of the storage box 1 and wound. Insert it in the hollow part 2B of the heart. The support pieces 25A and 25B are in contact with each other to support the winding core 2A at the top of the hollow portion 2B, while the roll-shaped sheet 2 is separated from the inner surfaces of the side surface 4 and the bottom surface 5 of the storage box, and the sheet 2 is pulled out. Then, the winding core 2A smoothly rotates around the support pieces 25A and 25B (see also FIG. 2B).

In the storage box 1 configured as described above, when the sheet 2 is pulled out, the core 2A rotates to send out the sheet 2, and the outer lid 12 and the tongue-shaped piece 14 sandwich the sheet 1 and The sliding resistance acts so as not to increase the delivery amount unnecessarily, so the seat will not be pulled out more than the required amount. The pulled-out sheet 2 can be cut at a required portion by using the cutting unit 16.

FIG. 4 is a development view of the storage box 1 when the inner lid 11 is placed at the upper end. In the figure, the solid line shows the outline, the one-dot chain line shows the inward folding curve, the two-dot chain line shows the outward folding curve, and the dotted line shows the cutting perforation. The inner lid 11 of the top surface 3 is cut off at a portion surrounded by the first and second perforations 51 and 52, and the tongue-shaped piece 14 is bent outward along the first folding curve 55 to pull out the opening 13 Occurs. The outline of the tongue piece 14 is a symmetrical curve, and only the tops 14A at the center and the left and right sides are in contact with the lower surface of the outer lid 12. The free ends of the side flaps 11A extending to both sides are insertion portions 11B into the inside of the storage box 1. The outer lid 12 of the top surface 3 is located at the lower end of the developed view, and the lower edge thereof is finished in a sawtooth shape so as to form the cut portion 16. The outer lid 12 has first and second adhesive portions 53 and 54 for adhering to the upper surface of the inner lid 11. Inside the second adhesive portion 54, there is a third perforation 56.

In order to assemble the storage box 1 from the development view, the roll-shaped sheet 2 (not shown) is placed inside, and each of the sheets extending in the width direction is arranged so that the outer lid 12 overlaps the upper surface of the inner lid 11. The inner lid 11, the side surface 4, the bottom surface 5, and the outer lid 12 are sequentially bent along the folding curve to bond the first and second adhesive portions 53 and 54 to the inner lid 11. Next, the flaps 4A and 4B with the support pieces 25A and 25B and the support pieces 25A and 25B are bent, and the bent support pieces 25A and 25B are inserted into the winding core 2A (not shown). Subsequently, the end face flap 11A is bent and the insertion portion 11B is inserted into the storage box 1. Lastly, the side flap 22 of the outer lid 12 is bent and overlapped on the end face flap 11A, and the adhesive flaps 16A extending from both sides of the cut portion 16 are adhered to the end face flap 11A.

When the customer uses the storage box 1, the outer lid 12 is cut open along the third perforation 56, and then the inner lid 11 is cut at the first and second perforations 51 and 52 to form a tongue piece. 14 is bent outward to form an outlet 13, and the tip of the sheet 2 is taken out. The outer lid 12 is closed and the engaged portion 23 is inserted into the slit 24.

The length of the slit 24 is preferably slightly longer than the diameter of the engaged portion 23. By doing so, the force that tries to open the outer lid 12 can be received by the entire length of the slit, and a large force locally acts on the slit 24 and the engaged portion 23 to damage them. Disappears. The relationship between the slit 24 and the base line 27 of the engaged portion is opposite to that in the illustrated example, and the slit 24 may be inclined. It is preferable to use the core 2A for the roll-shaped sheet 2, but it is possible to use the core 2A depending on the properties of the sheet 2. In order for the roll-shaped sheet 2 to rotate smoothly, it is preferable to make the outer dimensions of the storage box 1 a little larger in advance so that the roll does not contact the side surface 4 and the bottom surface 5. Although not shown in the drawing, when the roll-shaped sheet 2 is pulled out relatively strongly, the roll rotates excessively due to the rotational inertia, so that the sheet 2 is slackened or wrinkled in the storage box. In order to prevent the roll from rotating smoothly during the next drawing operation of the sheet 2, the end surfaces of the support pieces 25A and 25B that come into contact with the inner surface of the winding core 2A are formed into rough surfaces, The friction coefficient may be relatively high and the support piece may be reinforced, or at least the end face may be coated with a sponge material such as polyurethane. Furthermore, the support pieces 25A and 25B may be formed so as to have a tubular shape as a whole, or the two flaps 4A and 4B may be replaced by one flap, and the flaps may be tubular. A body supporting piece may be formed.

[0025]

[Effect of device]

 In the storage box according to the present invention, since the roll-shaped sheet is rotatable around the support piece as a support shaft, the rotation is smooth, and the sheet is always rotated by the tongue-shaped piece of the inner lid with a constant force. It is pressed against the lid, and the sliding resistance when pulling it out is constant regardless of the remaining amount of the sheet, so it is easy to pull out exactly the required amount of sheet, and there is no risk of pulling out extra.

If a part of the outer lid is diverted to the cut portion, the outer lid is easier to manufacture and less costly than the conventional technique in which the cut portion is made of a metal material.
