Abstract

(57) [Summary] [Purpose] In order to be able to widely reuse conventional PET bottles, in addition to the small-diameter injection port on the head, the functions of the wide-diameter part injection port and lid are required. is there. Therefore, after the pet bottle is cut into slices, the connecting portions are preliminarily integrally formed above and below the cutting allowance so that the functions of the inlet and the lid can be obtained. By improving the shape, it is possible to increase the strength and to take in and out things that could not be put in through a small-diameter inlet, which also contributes to saving resources and energy. [Structure] It is constituted by a structure in which a close contact portion and a screw portion are provided above and below a cutting margin of a ring slice, or a structure integrally formed into a shape capable of fitting.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a container such as a PET bottle which has a wide diameter injection port in addition to a small diameter injection port in a container such as a disposable PET bottle to improve reusability after use.

[0002]

[Prior art]

 The purpose of conventional containers such as PET bottles is to store liquid, and there is only a small diameter injection port on the head.After use, you can carry drinking water, cut it in half and use it as a vase substitute, small container. It is only reused for example. The material is easy to process, it is still not sufficiently clean, and it has to be discarded without material deterioration over time, which is becoming a problem in terms of resource utilization and the global environment. In order to increase the reuse rate, it is sufficient to use the small-diameter inlet as it is and provide a mouth and a lid that allow items of the wide-diameter part to be easily taken in and out, but this is not taken into consideration. There was a lot of financial and resource waste because I had to buy new bottles.

[0003]

[Issues to be solved by the device]

 The present invention aims to provide a parent-child capped bottle with high reusability that can be used even in the size of the wide-diameter part by cutting the wide-diameter part into slices after use in order to solve the problems of the conventional example. To do.

[0004]

[Means for solving problems]

 According to the present invention, the joint portion of the upper connecting portion 1 and the lower connected portion 2 which engages with the upper connecting portion 1 is integrally formed in advance in the wide-diameter portion of the container body, and this boundary is cut into a ring to separate them. A joint that can be connected and separated airtightly is provided. The structure of the joint uses a screwing method, an inserting method, a clamping method, or the like. Further, without forming the joint portion of the upper connecting portion 1 and the lower connected portion 2 to be engaged with the upper connecting portion 1 integrally, separately from the container body, a joint component that can be airtightly connected and separated is manufactured and cut after cutting. The end surface of the joint is inserted into a groove provided in each joint to be integrated.

[0005]

[Action]

 After use, it can be connected and separated even if it is separated by cutting the boundary into circles, so the inside can be easily cleaned, and in addition to liquids, things with a wide diameter part can be put in and reusability is improved. Also, since the joint part and joint parts are formed thicker than the thickness of the container body, holding this part makes it difficult to deform and easy to handle.

[0006]

【Example】

 An embodiment of a parent-child capped bottle according to the present invention that achieves the above object will be described with reference to the schematic sectional views of FIGS. 1 and 2. FIG. 1 shows a cross section in which a male part 4 is provided under the upper connection part 1 and a lower part to be connected 2 is provided integrally with the female thread part 5 under the ring cutting line in the wide diameter part of the upper part of the bottle as much as possible. . The lower connecting portion 2 is provided with a packing groove 3 to improve airtightness. FIG. 1 is a schematic cross-sectional view showing a state in which a knife or the like is used to cut and connect along a circular cutting line. Since it is only necessary to secure the airtightness at the connection portion, the screw may not be provided on the entire circumference, and the unevenness may be formed by the thickness of the main body.

An embodiment according to claim 2 will be described with reference to FIG. 3 showing schematic cross sections before and after cutting. The upper container 7 and the lower container 8 are arranged so that they are fitted slightly tightly at the connecting portion 10, the outside of the upper container 7 is inside of the lower container 8, and they are connected together by a cutting allowance 9. There is. If there is no problem in the molding die or process, the upper container 7 can be covered by making the inside of the upper container 7 the outside of the lower container 8. The cutting allowance 9 also serves as reinforcement. If the consumer wants to increase the diameter, the cutting allowance 9 may be cut into pieces with a knife. When making fruit liquor, use adhesive tape to assist in sealing.

For a conventional bottle not related to the present invention, as shown in FIG. 4, a connecting part having an insertion groove 11 in each of the upper connecting part 1 and the lower connected part 2 can be separately manufactured and sold separately. To

[0009]

[Effect of device]

 The parent-child capped bottle according to the present invention has the following effects. (1) It can be used as in the past, and it is convenient because it can be widely reused in containers other than liquids even after use. (2) Even when making fruit liquor, the space is efficient and the contents look good, and you can get only fruit liquor directly from the child cap without using a ladle. (3) Easy cleaning due to the wide diameter. (4) Since it has a long life and can be widely reused and substituted, it can contribute to the saving of resources and energy for bottles and substitutes. (5) The number of rings and grooves increases, the bottle itself becomes strong, and it is difficult to deform and easy to handle. (6) Contribute to the expansion of sales of products with the added value as described above.
