Description

[Detailed description of the invention] The present invention relates to a storage device for a cylindrical wound thin film body such as aluminum foil, and the storage device has two opposing inner walls whose side walls are double-layered. By forming a notch in the shape and roughly shaped notches in the two opposing outer walls, for example, when using aluminum foil in the storage device, it is possible to By folding the notch part inward and inserting this folded piece into the aluminum foil winding core and hooking it, the entire aluminum foil will remain in the storage case even if the tip of the aluminum foil is pulled out. Since the tip of the aluminum foil does not protrude, pulling out and cutting the tip of the aluminum foil becomes extremely easy and smooth.Furthermore, the folding piece hooked onto the aluminum foil is oriented vertically, so even if a large force is applied to the folding piece, it will not fold back. The pieces are not easily damaged and do not lose their latching effect, and in particular, the vertically folded pieces of the outer wall are regulated by the horizontally folded pieces of the inner wall. Therefore, the folded pieces that are hooked on the aluminum foil will be restored and will not become unlatched on the aluminum foil, and the work of forming the folded pieces that will be hooked on the aluminum foil will be easy, and the storage tool To provide a storage tool in which aluminum foil can be stored easily and smoothly since there is no protrusion inside the storage tool.

Conventionally, it has been proposed to provide a stopper on the side wall of a storage case for cylindrically wound aluminum foil, etc., to prevent the entire aluminum foil from flying out when the tip of the aluminum foil is pulled out. There is. It is also considered that this stopper may be used so as not to interfere with the aluminum foil storage operation when storing the aluminum foil in the storage case, that is, to use a part of the side wall of the storage case itself. For example, as shown in FIG. 1, a semicircular notch 2 is formed in the outer wall 1 of the storage case, and notches 4 and 4' are formed in the inner wall 3. Push the cut 2 part of 1 inward and bend it inward to form the bent piece 5,
A storage case has been proposed in which the folded piece 6 of the inner wall body 3 prevents the folded piece 5 from being restored. However, in this storage case, the aluminum foil is hung on the folding piece 5 bent in the horizontal direction, so if a slightly large force is applied to the folding piece 5, the folding piece 5 will bend 180 degrees. As a result, the bending piece 5 loses its ability to hold the aluminum foil.

Further, as shown in FIG. 2, a substantially square-shaped notch 11 is formed in the outer wall 10 of the storage case, and substantially V-shaped notches 13, 13' are formed in the inner wall 12. When the part of the notch 11 of 10 is pushed inward and bent inward to form the bent piece 14, the part of the notch of the inner wall body 12 is bent to form the bent piece 15,1.
5' is formed, and an aluminum foil inside the storage case is hung by the bent pieces 15, 15'.

However, in this storage case, the aluminum foil is hung on diagonally bent pieces 15, 15'.
Therefore, if a slightly large force is applied to the bent pieces 15, 15', the base portions of the bent pieces 15, 15' tend to break, and a sufficient stopper effect cannot be exerted.

As a result of investigating this point, it was discovered that the bent piece that acts as a stopper supporting the aluminum foil winding core is not in the same direction as the tensile force acting when the aluminum foil is pulled out. This resulted in the devising of a storage case in which the bent piece that acts as a stopper is oriented in the same direction as the force acting when the aluminum foil is pulled out, and which prevents the bent piece from easily returning to its original shape and no longer functioning as a stopper, and which allows the user to easily assemble the stopper member.

Examples of the storage device according to the present invention will be described below.

FIG. 3 is a developed explanatory view of the storage device according to the present invention, and FIGS. 4a and 4b are explanatory views of the storage device in an assembled state.

In the figure, reference numeral 20 is a plate made of, for example, cardboard or the like and formed into a predetermined shape, and a fold is formed for folding the plate 20 to construct a predetermined storage case. Note that 21 is a serrated blade attached to a predetermined position on the plate body 20, and is located at the upper end of the front surface of the storage case A when the storage case A is assembled.

22 and 22' are the parts that will become the outer walls of the storage case A when the plate 20 is bent and the storage case A is assembled, and 23 and 23' are the parts that will become the inner walls of the storage case A. be. Of these side walls,
As shown in FIG. 3, the inner wall portions 23, 23' are formed with substantially square-shaped notches 24, 24', and the outer wall portions 22, 22' are formed with third grooves 24, 24'.
As shown in the figure, approximately H-shaped cuts 25, 22
5' is formed. These notches 24,2
4' and the notches 25, 25' relative to each other when the plate body 20 is bent and the storage case A is assembled.
The cutouts 25, 25' of the outer wall portion overlap the cutouts 24, 24' of the inner wall portion. Then, the notches 25, 25 of the outer wall body are made so that when the parts of the notches 25, 25 are bent inward, the bent pieces can penetrate into the inside from the notches part of the inner wall body.
The dimensions of the notches 24, 24', 25, and 25' are formed so that the notch end gap m at the notches 5 and 25' is shorter than the notch end gap n at the notches 24 and 24' of the inner wall portion. There is.

Assemble the plate body 20 formed as described above,
A storage case A as shown in FIG. 4a is constructed.
Storage case A at this stage is storage case A.
Since the notch in the side wall is not pressed and bent,
The work of storing, for example, aluminum foil in the storage case A can be done easily and smoothly as before. That is, there is no protruding part inside the storage case A that would get in the way of inserting the aluminum foil.

When using the aluminum foil, that is, when using it for the first time after purchasing the case in which the aluminum foil is stored, if you apply pressure while pushing the notch in the direction of the arrow, the result will be as shown in Figure 4b. , the notch part of the side wall of storage case A is bent inward to form bent pieces 30, 30', 31,
31', 32, and 32' are constructed. That is, by configuring the storage case as shown in FIG. 4b while the aluminum foil is in use, the bent piece 3 can be inserted into the winding core of the aluminum foil B wound into a cylindrical shape.
0 and 30' are inserted, and when the tip of aluminum foil B is pulled to pull out the aluminum foil, the bent pieces 30 and 30' act as a stopper and pop out from the aluminum foil B and the storage case. There is nothing like that at all. Moreover, this bent piece 3
Since the planes 0 and 30' are perpendicular to the top and bottom surfaces of the storage case A, that is, parallel to the direction of the force acting on the folding pieces 30 and 30', the folding pieces 3
Even if a large force is applied to the bent pieces 30,
There is no possibility that the 30' will be bent or torn off at the base. In other words, the durability of the aluminum foil stopper effect provided by the bent pieces 30, 30' is excellent.
Moreover, the bent pieces 31 and 3 are placed between the bent pieces 30 and 30'.
1', the restoring force of the bent pieces 30, 30' is restricted by the bent pieces 31, 31', and the bent pieces 30, 30' do not return to their original positions. , it does not lose its role as a stopper for aluminum foil. Also, bent pieces 30,3
The bending pieces 32, 32' regulate the bending angle of the bending pieces 30, 30' so that the bending pieces 30, 30' do not bend more than necessary, for example, by 180 degrees.
0', an extremely large force acts on the bent pieces 30, 3
Even if 0' is damaged, the bent pieces 32, 32' will remain the bent piece 3.
This means that it functions as a stopper instead of 0.30', and since the stopper by the bent piece is doubled, it is extremely excellent.

As shown in the drawings of this embodiment, the side wall of the storage case is partially triple-layered, and if one end of the innermost wall of this side wall is located at the base of the folded piece, the folded piece The bending piece will not be bent more than necessary, and the stopper effect will be more reliable.

Moreover, instead of forming a substantially square-shaped cut, for example, the cut 24, only in one inner wall portion 23 as in the above embodiment, for example, as shown in FIG. Approximately at the ends of the inner wall portions 41 and 42
Each half of the shape cut, that is, the inner wall portion 41,
Notches 43 and 44 each having a substantially square shape are formed in each of the notches 42, and when assembled as a storage case, these cuts 43 and 44 form a notch having a substantially square shape as a whole. Good too. In addition, 45
4 is an outer wall portion, and 46 is a substantially H-shaped notch, which is formed in the same manner as in the above embodiment.

As mentioned above, the storage device according to the present invention is a storage device in which the side wall bodies are overlapped at least twice, and the two opposing inner wall bodies are provided with a substantially square-shaped cut in the vertical direction, and this cut is provided with a substantially square-shaped cut in the vertical direction. Since the two outer walls facing each other at corresponding positions are formed with roughly shaped notches in the vertical direction and have a width shorter than the interval between the cut ends in the vertical direction of the inner wall body, it is possible to fit inside the storage device. For example, when inserting a cylindrically wound aluminum foil, there is no protruding part inside the storage tool, so the work of storing the aluminum foil can be done smoothly and efficiently, and when the aluminum foil is used, the storage tool is If you apply force to the notch on the side to form a bent piece on the inside, you can prevent the bent piece from getting caught in the aluminum foil winding core when pulling the tip of the aluminum foil out. It acts as a stopper, and there is no chance of the aluminum foil popping out of the storage tool, and the process of pulling out the tip of the aluminum foil becomes smoother.
Moreover, since the bent piece that serves as the aluminum foil stopper is perpendicular to the bottom surface of the storage device, the strength of this bent piece is high, making it difficult to tear at the base, and the bending piece is not easily damaged. It has never been said that the bent piece does not bend 180 degrees and become a stopper when the bending piece acts, and the bending angle of the bent piece is different from that of the inner wall and the outer wall. Since the bent pieces are restrained from each other by their own restoring force, the bent pieces return to their original state by their own restoring force, and there is no possibility that they will lose their stopper action.Furthermore, when forming the bent pieces, no force is applied to the notch. It has the advantage of being easy to form as it only requires adding .
