Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is a crusher that enables aluminum cans and steel cans to be easily squeezed with a light force while being crushed to reduce the volume of the cans without the need for a dedicated device. It is related to bull cans and can contribute to beautification of the environment.

[Prior art]

Aluminum cans, steel cans and the like are widely used as containers for storing soft drinks, alcoholic drinks and the like. These cans are discarded as empty cans after use. It is a common sight to see these empty cans overflowing from a trash can beside or elsewhere.

If the empty cans can be crushed, the shape of the empty cans can be downsized, and as a result, the volume of the empty cans to be discarded can be reduced, but metal cans such as aluminum cans and steel cans can be reduced. It takes quite a lot of force to crush, and it is very difficult to crush it completely.

[Problems to be solved by the device]

[0004] Therefore, a press device or the like for crushing empty cans has been considered and put into practical use, but these must be set in the press device each time and the usage is troublesome. However, in reality, there are difficulties such as having to prepare the device. . In addition, there is a danger of accidents when used by people unfamiliar with the machine, and in addition to the need to install the device, there is a practical problem that it can not be installed easily anywhere. It was

That is, in order to crush the empty cans to achieve volume reduction, a special device for crushing the empty cans is not prepared as in the conventional case, but a structure that allows the cans to be easily crushed is used. When this happens, you can easily crush it by hand to reduce the volume. It is also desirable to be able to crush it so that it is as small as possible.

[0006]

[Means for Solving the Problems]

 Therefore, in order to solve the above-mentioned problems, the crushable can according to the present invention has a straight-line shape in which the can is tubularly oriented in the vertical direction of the can at an angle of 60 to 90 degrees with respect to the horizontal cross section of the can. A plurality of mountain folds are formed at desired intervals, and an oblique linear valley fold that contacts the lower end of one mountain fold and the upper end of the other mountain fold is formed between the adjacent mountain folds.

[0007]

[Action]

 That is, by forming the mountain folds and valley folds as described above, when the can main body is twisted in the direction in which the distance between the mountain folds and valley folds is narrowed, the valley folds are inside the can main body, and the mountain folds are also formed. Are deformed so that they are folded to the outside of the can body, respectively, and as a result, the top and bottom of the can body are deformed as if they were compressed, resulting in a smaller size and a smaller overall volume. The volume can be reduced.

[0008]

【Example】

 An embodiment of the crushable can according to the present invention will now be described with reference to the drawings. 1 is a can main body whose contour shape is known, and 2 is formed in the vertical direction of the can main body 1. It is a straight mountain fold. The mountain folds 2 are formed at an angle of 60 to 90 degrees with respect to the horizontal cross section of the can body, and 4 to 12 are formed at regular intervals. In each figure showing this embodiment, six examples are shown.

As for the shape of the mountain fold 2, for example, as shown in FIG. 2 (1), the mountain fold 2 is formed by pressing and projecting in a U-shape from the inside to the outside of the can body 1, or As shown in (2), a U-shaped groove may be formed from the inside of the can body 1 to the wall thickness of the tubular portion 3. In any of these cases, it may be V-shaped instead of U-shaped.

Reference numeral 4 denotes a linear valley fold portion (shown by a dotted line in the drawing) formed diagonally with respect to a quadrangle formed by the adjacent mountain fold portions 2 and upper and lower ridge lines thereof. Regarding the shape of the valley fold portion 4, for example, as shown in FIG. 3 (1), it is formed by pressing and projecting in a U-shape from the outer side to the inner side of the can body 1, or as shown in FIG. As shown, a U-shaped groove may be formed from the outside of the can body 1 with respect to the wall thickness of the tubular portion 3. In any of these cases, it may be V-shaped instead of U-shaped.

As described above, the structure of the crushable can according to the present invention described above is not limited to that shown in FIG. 1, but the entire can body 1 may be formed into a rectangular tube shape as shown in FIG. In some cases, only the tubular portion 3 of the can body 1 is formed into a rectangular tubular shape, and the surface formed by the mountain fold portion 2 and the valley fold portion 4 is formed to have a diamond cut shape as shown in FIG. . Furthermore, the cylindrical portion 3 may be formed of a corrugated plate member oriented in the circumferential direction, and a valley fold that obliquely crosses the cylindrical portion 3 may be formed.

In addition, as shown in FIG. 6, a strip-shaped intermediate portion 5 is formed substantially in the middle of the tubular portion 3 of the can body 1. In this case, upper and lower mountain folds of the intermediate portion 5 are formed. 2 and the valley folds 4 have the same structure as that shown in FIG. 1, while forming two mountain folds 2 ′ and 2 ″ on the upper edge and the lower edge of the intermediate portion 5 respectively. Of the two mountain folds, the highest and lowest mountain folds 2'may be intermittent (see Figure 7).

In the case where the intermediate portion 5 is formed, for example, as shown in FIG. 8, the intermediate portion 5 itself is formed in a wide mountain fold shape, and intermittent mountain fold portions are formed along the top and bottom of the mountain fold portion. 2 "may be formed.

In the above, the widths and depths of the mountain folds 2, 2 ′, 2 ″ and the valley folds 4 may both be about 0.1 to 2.0 mm, which is the case when it is soft like an aluminum can. The depth may be shallow and narrow, but if it is relatively hard such as a steel can, it should be wide and deep.

In the figure, 6 is an upper surface of the can body 1, and 7 is a bottom portion.

Next, how to crush the crushable can according to the present invention will be described with reference to FIG. First, as shown in FIGS. 9 (1) and 9 (2), the can body 1 in an empty can is twisted by hand by hand in the opposite directions. Then, the valley folds 4 are deformed so as to face the inside of the can body 1, and the mountain folds 2 are deformed so as to face the outside, and as a result, the valley folds 4 are deformed so as to be folded. When the can is almost completely twisted, it is crushed by hand from above and below as shown in Fig. 9 (3).

Further, in the case of a long can provided with the intermediate portion 5 shown in FIG. 6, when the can body 1 is twisted from above and below, the intermediate portion 5 has edge-shaped mountain folds 2 ′ and 2 ″ at the top and bottom thereof. Due to its presence, the middle part 5 itself is not deformed, so that the cans are twisted between the middle part 5 and the top 6 and between the middle part 5 and the bottom 7, respectively, so that the two cans are the same. When crushed from above and below in this state, the intermediate portion 7 is difficult to deform, so the deformed can is stored in this intermediate portion 5, and the height of the entire can is increased. It is crushed to the height of.

[0018]

[Effect of device]

 As described above, according to the crushable can according to the present invention, a straight mountain fold in the vertical direction of the can at an angle of 60 to 90 degrees with respect to the horizontal cross section of the can is provided in the can. A plurality of them are formed at desired intervals, and between the adjacent mountain folds, diagonal linear folds are formed which contact the lower end of one mountain fold and the upper end of the other mountain fold. When the can main body is twisted in the direction in which the gap between the valley folds is narrowed, the valley folds are bent inside the main body of the can, and the mountain folds are bent outside the main body of the can. As a result, the top and bottom of the can body is deformed and miniaturized as if it were compressed, and the overall volume is reduced. Therefore, the volume of empty cans can be reduced, and empty cans can be prevented from overflowing the trash can. It can be expected to beautify the home, office, town, and other environments. With a cormorant effect.
