JPH0542153U - Synthetic resin container - Google Patents

Abstract

(57) [Summary] [Purpose] When a synthetic resin container is discarded, it may be discarded with the lid attached. When recovering and regenerating such a container, remove the cover and collect it. . To save this hassle, we provide a container that can be collected without removing the lid. [Structure] A container made of synthetic resin and a lid made of synthetic resin attached to the container have different hardness, and
They were made of the same kind of synthetic resin.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a synthetic resin container such as a bottle.

[0002]

[Prior Art]

 Conventionally, in a container such as a bottle made of a synthetic resin, various liquid products and the like are usually contained in the container, and the container made of a synthetic resin is put on the market. In that case, the lid is generally made of a synthetic resin different from the synthetic resin forming the container. For example, the container is made of polyethylene terephthalate, and the lid is made of polyethylene. In this case, the lid is made of polyethylene to be more flexible than the container, thus enhancing the hermeticity.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional container has the following problems. That is, when the synthetic resin container is discarded after use, it may be discarded with the lid attached to the mouth of the container. And when recovering and reclaiming such containers, the lid must be removed one by one. Although not shown in the drawings, these projections formed on the lid are press-fitted to the engaging portions such as recesses generally formed in the mouth of the container. , Discard the lid and collect and recycle only the container. This work is tedious. The present invention has been made to solve such a problem, and its purpose is to provide a container made of synthetic resin which can be collected and regenerated extremely easily without the trouble of removing the lid as described above. It is to be.

[0004]

[Means for Solving the Problems]

 This invention which achieves the above-mentioned object is described as follows: a container body 1 made of synthetic resin; a cap 2 formed separately from the body 1 and attached to the body 1; And a cap 2 made of the same type of synthetic resin as that of the main body 1;

Further, a container body 1 made of a synthetic resin; a packing 4 formed separately from the body 1 and attached to the body 1; having a hardness different from that of the body 1; The packing 4 made of the same kind of synthetic resin as the body 1; the cap 2 mounted on the body 1 through the packing 4; the cap made of the same kind of synthetic resin as the body 1 2; a container made of synthetic resin.

[0006]

[Action]

 The main body 1 of the container made of synthetic resin according to the present invention is fitted with a cap 2 after containing products such as liquid products therein. In this case, since there is a difference in hardness between the both 1 and 2, the one with the smaller hardness is deformed and the sealing is performed. Then, after using the contents of this container, when disposing of the container with the cap 2 still attached, dispose the cap 2 because it is the same kind of synthetic resin as the main body 1 of the container as described above. Instead, it can be recovered as it is, and thus can be recovered and regenerated extremely easily.

[0007]

【Example】

 In FIG. 1, reference numeral 1 is a container made of synthetic resin, for example, a bottle. The main body 1 is made of polyethylene terephthalate as an example. However, the main body 1 may be made of an appropriate publicly known synthetic resin such as polypropylene or polyethylene. Reference numeral 2 denotes a cap, which is made of polyethylene terephthalate, which is the same type of resin as that of the main body 1 of the container, but has a hardness smaller than that of the main body 1 as an example. In the figure, 5 is an engaging concave portion, and 6 is an engaging convex portion. In FIG. 2, numeral 4 denotes packing, and in the case shown in the figure, it is made of polyethylene terephthalate, which is the same kind of synthetic resin as the body 1 of the container, and is formed to have a hardness smaller than that of the body 1 of the container. It was Further, in this figure, the cap 2 is formed to have hardness smaller than that of the main body 1 of the container and larger than that of the packing 4 in this case. However, in this case, the cap 2 may be formed to have the same hardness as the main body 1 of the container. In this case, the cap 2 was formed of the same resin as the main body 1 of the container, polyethylene terephthalate.

The container body 1, the cap 2 and the packing 4 are made of polyethylene, and their hardnesses are as follows: container body 1> cap 2 and container body 1> cap 2> packing 4 And the container body 1 = cap 2> packing 4. The main body 1 of the container made of synthetic resin may be of a type screwed with the cap 2 as shown in FIG. 3, and as shown in FIG. 4 and FIG. It may be provided with a sealing portion 7 which is deformable by the upper end portion 6.

[0009]

[Effect of the device]

 The present invention is configured as described above, and since the container body 1 and the cap 2 or the container body 1 and the packing 4 have different hardnesses, the one having lower hardness is deformed and closed when closed. When the body 1 of the container is discarded, even if the cap 2 or the cap 2 is attached via the packing 4, it can be recovered and regenerated as it is without removing them. An easy-to-use synthetic resin container can be provided.
