Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a plastic bottle for storing mineral water, juice and other liquids in an internal space, and a plastic bottle connecting structure formed by connecting a plurality of the plastic bottles.

[0002]

[Prior art]

 FIG. 2 (A) is a longitudinal sectional view of a conventional mineral water PET bottle. FIG. 2B is an enlarged longitudinal sectional view of a region 101 in FIG. As shown in FIG. 2 (B), an external male screw 12 is formed on the outer periphery of the entrance through which the liquid enters and exits. On the inside of the lid 14, a female screw to be screwed with the male screw 12 at the mouth is formed. The packing 13 is fitted on the surface of the lid 14 which is in contact with the end of the entrance. The main body 31 is made of PET resin (polyethylene terephthalate) and is a container made by blow molding and suitable for storing a liquid.

[0003]

[Problems to be solved by the invention]

 When the conventional PET bottles shown in FIG. 2 are collected, they are arranged on the floor surface for a considerable period of time, for example, one week or two weeks at home. At that time, the floor space is occupied widely, which is a hindrance until the collected vehicles come around. PET resins have the drawback that they generate high temperatures during incineration and are liable to damage the incinerator, which in turn results in high incineration costs. Such conventional PET bottles were developed solely for the purpose of containing liquids and distributing beverages at low cost, and no consideration was given to reusing them. Therefore, the purpose of the present invention is to provide plastic bottles that are designed for reuse from the beginning.
