Abstract

(57) [Summary] [Purpose] The purpose of the present invention is to reduce the processing cost by facilitating dismantling for the purpose of more space saving when collecting disposable containers, and to promote recycling of container materials. [Structure] Disposable containers of various shapes are provided with notches that can be disassembled without tools after use along the major axis direction of the container.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a disposable container made of synthetic resin such as plastic.

[0002]

[Prior art]

 Speaking of PET bottles, the body part is inflated and cut at the largest radius after use, and the same type of PET bottles are stacked separately on top and bottom to reduce the volume for collection. Things were invented. This container is supposed to be dismantled. However, other than that, there has been no disposable container that is supposed to be dismantled so that the volume after use becomes smaller.

[0003]

[Problems to be solved by the device]

 This had the following disadvantages. (A) The above-mentioned plastic bottle had a geometrical constraint that the body part had to be inflated, and that the body part had to have fewer irregularities when viewed from above and below. (B) The above PET bottle alone could not save the volume at the time of collection unless the same type PET bottle was stored. (C) When the container material is reused, the metal lid must be removed, but in the case of the above-mentioned PET bottle, when the lid is recovered without removing the lid, the mouth part of the container overlaps dozens. It took more time to get the lid on. (D) It took a lot of time to disassemble many disposable containers, and it was costly to recover the containers because they were transported in a large volume without being dismantled. (E) Along with this, the reuse of container materials was hindered. The present invention has been made to eliminate these disadvantages.

[0004]

[Means for Solving the Problems] A main body having a shape similar to that of various disposable containers is provided with a notch for enabling disassembly along the major axis direction so that the container can be easily disassembled without a tool.

[0005]

[Action]

 This container is used in the same way as the existing disposable container, and after the original purpose of use is finished, it is disassembled without tools by using the cut portion made.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described.

Example 1 FIGS. 2 and 1 show a container before being disassembled according to Example 1 and a state of disassembly. Make a notch in a cylindrical container such as a PET bottle as shown by the chain line in Figure 2. When disassembling this, if the notch as shown in Fig. 7 is made, remove the mouth part together with the cap, and then pull the main body left and right to dismantle. In addition, when the notch is formed as shown in Fig. 8, the part is disassembled according to the notch by pulling the part toward you. Example 2 FIG. 3 shows a container of Example 2 before disassembly. As shown by the alternate long and short dash line in FIG. 3, a cut portion is made in the rectangular cylindrical container along the major axis direction and parallel to the side surface. Then dismantle as in the previous example. Practical example 3 FIG. 4 shows a container of Example 3 before disassembly. In the same rectangular cylindrical container as in Example 2, as shown by the alternate long and short dash line in FIG. 4, cut portions are formed along the major axis direction and diagonally as viewed from above. Then dismantle as in the previous example. Practical example 4 FIG. 5 shows a container of Example 4 before disassembly. Make a notch in a gourd-shaped container with the body part collapsed as shown by the chain line in Fig. 5. Then dismantle as in the previous example.

The reason why the bottom portion of Example 1 has a circular notch is that the central portion of the bottom is thick in the case of a pet bottle, but it is important to disassemble it efficiently in the major axis direction. If it can be disassembled even if it is connected in a straight line, there is no problem. In this case, cylindrical type, square tubular type and gourd type are taken as examples, but by providing notches for promoting dismantling along the major axis direction in the container body, space saving after use of any shape disposable You can make a container. Any notch can be used, such as a combination of kerf, weakening line, and tear groove, if disassembly is easy.

[0009]

[Effect of the invention]

 For disposable containers of any shape, it can be easily disassembled without tools after use to save the volume for collection. Moreover, it is not necessary to store the same type for that purpose. Even if you put it in a garbage bag with other garbage alone, as shown in Fig. 6, less space will be wasted and space will be saved compared to when the barrel is sliced. Even in the case where the same type is accumulated, as shown in Example 4, even in the case of the case where the body is sliced, it is not possible to stack the containers in many cases, and in many cases, the containers can be easily stacked. Also, since the mouths do not overlap, unlike the plastic bottles that have the body cut into slices, there is no additional work to remove the lid when reusing. Due to these effects, the collection cost of the container can be reduced and the material can be reused.
