Description

[Detailed description of the invention] The present invention relates to a storage device such as aluminum foil or plastic film, and the invention is directed to a storage device such as aluminum foil or plastic film, in which a cutting blade for a film-like material such as aluminum foil is used to cut the film-like material at the end of the surface constituting the storage material. By providing it only in a small area corresponding to the end of the direction, the length of the cutting blade can be shortened, and the number of parts can be reduced accordingly, resulting in a lower cost. To provide a storage tool which reduces installation work cost because the number of parts is reduced, and furthermore, eliminates the possibility of touching a cutting blade when gripping the storage tool, and which is less dangerous.

Conventionally, as shown in FIG. 1, storage tools such as aluminum foil have a serrated blade 2 along the entire length at the lower end 1'' of the front surface 1' of a casing 1 made by folding cardboard or the like. For example, an aluminum foil 3 wrapped around a core body is stored in such a storage device, and the aluminum foil is pulled out and the stretched aluminum foil is placed in a predetermined position. When the length is reached, the aluminum foil is bent against a serrated blade, and force is applied to the aluminum foil to cut it.

However, in a storage device with such a configuration, the serrated blade is attached over the entire length of the housing part 1 in the longitudinal direction, so for example, when the storage device is held, the serrated blade attached to the storage device is always exposed. You will be able to touch it, which is extremely dangerous. Therefore, if the serrated blade is attached to the upper end of the front surface of the housing, the danger will be relatively reduced. However, even with this arrangement, when the tip 4' of the lid 4 is inserted into the casing 1, if you hold the center part of such a storage tool, the lid surface 4'' of the lid 4 will not touch the casing. The serrated blade will sink into the body part 1 a little, and the serrated blade will come into contact with your hand, so the danger cannot be completely eliminated.For this reason, when handling the storage tool, be careful not to touch the serrated blade with your hand. In particular, aluminum foil, etc., is now common in households as an everyday household item, and households with young children should be careful when storing it. Otherwise, there is a high risk of injury from the serrated blade.Also, since the serrated blade is attached to the entire length of the housing, more parts and materials are required, which only increases costs. In addition, many installation locations are required, and the installation work cost is correspondingly high.

The present invention eliminates the above drawbacks, and examples thereof will be described below.

FIG. 2 is an explanatory diagram of the first embodiment of the storage device according to the present invention. In the figure, 10 is a storage case made by folding cardboard or the like, and 11 is a lid. 12
is a front surface forming the housing section 10, and 13 is a surface bent from the side surface 14 forming the case section 10. 15 is a lid surface constituting the lid body portion 11;
Reference numeral 6 denotes an insertion surface constituting the lid portion 11.

In such a storage device, a saw-shaped blade 17 made of metal, for example, is attached only to the right end of a small area of the upper end 12' of the front surface 12 of the casing 10 so as to protrude from the upper end 12'.

Note that 18 is an aluminum foil wrapped around a core body, and is housed within the casing.

FIG. 3 is an explanatory diagram of the second embodiment of the storage device according to the present invention, and the configuration of the storage casing part and the lid body part is the same as that of the first embodiment.
It is almost the same as the example. That is,
20 is a housing part, 21 is a lid part, 22 is a front surface of the housing part, 24 is a side surface, 23 is a surface bent from the side surface 24, 25 is a lid surface of the lid body part, and 26 is an insertion surface.

In such a storage device, the serrated blade 27 is attached only to the right end of a small area of the tip 26' of the insertion surface 26 of the lid body 21 so as to protrude slightly from the tip 26'.

Note that 28 is an aluminum foil wrapped around the core, and is housed in the housing.

FIG. 4 is an explanatory diagram of the third embodiment of the storage device according to the present invention, and the structure of the storage casing and the lid body is the same as that of the first embodiment.
It is almost the same as the example. That is,
30 is a housing part, 31 is a lid part, 32 is a front surface of the housing part, 34 is a side surface, 33 is a surface bent from the side surface 34, 35 is a lid surface of the lid body part, and 36 is an insertion surface.

In such a storage device, the serrated blade 3 is provided only in a small area of the lower end 32' of the front surface 32 of the housing portion 30.
7 was attached so as to protrude slightly from the lower end 32'.

Note that 38 is an aluminum foil wrapped around the core, and is housed in the housing.

When the storage device configured as described above is used, for example, the stored thin film sheet made of aluminum foil or synthetic resin such as polyvinylidene chloride with a small tensile elongation rate can be pulled out and stretched out to a predetermined length. After that, an aluminum foil or the like is applied to the serrated blade 2 and bent, and cutting is started by applying force. In this case, since there is a cutting blade such as a serrated blade at the beginning of the cut, the cut can be easily made with a small force, and once the cutting line is made, it can be easily continued along the bent part even without the serrated blade etc. so that it can be cut. That is, if the cutting blade of the membrane-like body is provided only at a position corresponding to the beginning of cutting, it can sufficiently fulfill its role. Moreover, since the cutting blade is provided only in a portion, the number of parts for the cutting blade can be reduced accordingly, and the cost can be reduced accordingly. or,
The number of attachment points for the cutting blade is reduced, which makes the attachment work easier and the work cost lower. Furthermore, since the cutting blade is only provided at the edge when the storage device is held in hand, the cutting blade will not shake in the hand even if the central portion is easily held in the hand, and therefore there is no danger. Especially the first
In the case of the example, when the insertion surface is stored inside the casing, if the center part is held, the lid surface will sink in a little, and if a cutting blade is provided in this part, there is a risk of injury to hands etc. On the other hand, the lid surface is relatively hard to sink into at the end portion, so even if a cutting blade is provided at the end, the cutting blade will not protrude above the lid surface, so there is no risk of injuring hands or the like. Similarly, in the case of the second embodiment, since the cutting blade does not protrude during storage, there is no risk of injuring hands or the like. In addition, in the second embodiment, regardless of how the aluminum foil is inserted, it is almost impossible to cut it when cutting.
It can be bent 180 degrees and cuts the aluminum foil by pulling it toward you, making the cutting process particularly easy.

Note that the above example is for a right-handed person,
In the case of a left-handed person, it is sufficient to provide the cutting blade only at the left end. Therefore, considering both of these cases, cutting blades may be provided only at the left and right ends.

As mentioned above, the storage device according to the present invention has a storage device that stores a membrane-like body, and a small area that is located at the end of the surface constituting the housing body and approximately corresponds to the end of the membrane-like body in the cutting direction. Since the membrane-like cutting blade is provided only at the position, the length of the cutting blade to be provided can be shortened, and the number of parts can be reduced accordingly, resulting in a lower cost, and there are also fewer places to attach the cutting blade. Therefore, the installation work cost is reduced accordingly, and there is no protruding cutting blade in the center, which makes it easy to hold when holding the storage tool, so it does not hurt your hands at all. In the case of everyday household items such as thin films, there is no need to handle them carefully, making them extremely convenient.
