Problems solved by technology

[0004] In addition, it has been proposed to attach a cap with a large outer diameter to the small-diameter opening-side neck. However, if the cap-locking neck has the same diameter as the opening-side neck, strong locking force cannot be obtained. problem, and there is the problem of locking the neck in order to set the cap on the shoulder of the container so that the cap becomes large relative to the neck and up to the shoulder

Embodiment 1

[0077] exist Figure 1 to Figure 5 In the shown embodiment, the container main body 1 related to the present invention is provided with a cap locking neck 30 whose inner and outer diameters are larger than the opening side neck 13 on the container shoulder side neck 14 of the container neck 10. Therefore, a large cap that is easy to hold can be used, and a strong locking force can be obtained by locking the neck 30 with a thicker cap, and a large amount of content can be accommodated in the neck Effect.

[0078] In addition, since the present invention has a structure in which extrusion flexibility is imparted to the cap locking neck portion 30, it is effective to squeeze and pour a large amount of contents accommodated in the neck portion.

[0079] In addition, since the present invention has the structure of imparting the compression recovery elasticity to the cap locking neck 30, it is possible to squeeze and pour a large amount of content contained in the neck, and the re...

Embodiment 2

[0081] In the case of the illustrated embodiment, the cap locking neck portion 30 is provided on the container shoulder side neck portion 14 having a larger diameter than the opening side neck portion 13 of the container neck portion 10 .

[0082] As for the outer diameter of the thick neck, the thicker the outer diameter of the thin neck, the larger the cap locking neck 30 can be provided, and a correspondingly larger locking effect can be expected.

[0083] The outer diameter of the thick neck is about 1.2 times or more than the outer diameter of the thin neck. Ideally, 1.6 to 2.4 times is suitable for ordinary caps, but it may be less than that for special containers and caps. or above.

[0084] In the case of the illustrated embodiment, the cap locking neck portion 30 is made of a threaded fixing structure, and four large-pitch external thread portions 31 are provided at intervals within 90 degrees and in a non-overlapping manner, so that The inner rotation completes the ...

Embodiment 3

[0087] In addition, a stopper 32 for preventing reverse rotation is provided on the cap locking neck portion 30 of the container neck 10, and the stopper 32 is used to securely fix the attached cap.

[0088] In the case of the illustrated embodiment, four stoppers 32 are provided at 90-degree intervals on the boundary portion 23 close to the neck portion 13 on the opening side, and the stoppers on the cover side, which are omitted in the figure, are installed. , engages across the stopper 32 and prevents reverse rotation of the cover.

[0089] In addition, in the embodiment of the present invention, the stopper 32 is configured with a single-click stop-type engagement structure by engaging with the elastic deformation and releasing the elastic force, so that the stopper 32 can be fixed with a single-click feeling. cover.

Abstract

If the diameter of an opening side neck portion is decreased to minimize the contact surface between contents and air and a small cap is fitted on a container where there is the concern that exposure to air may alter the quality of contents in the container, there is not only the problem that a gap results between the cap top board and the container opening where adequate locking force is not available but the problem that force is required to open and close the lid, making removal and fitting troublesome. A container made so a large cap can be fitted thereto by providing a cap locking neck portion 30 whose inner and outer diameters are larger than an opening side neck portion 13 at a container should side neck portion 14 of a container neck 10.

Description

technical field [0001] The present invention relates to a container in which a cap that is larger than the neck on the opening side is arranged on the neck to lock the neck. Background technique [0002] When there is a risk of deterioration of the contents of the container when exposed to the air, the diameter of the neck on the opening side is reduced to reduce the contact area between the air and the contents and a cap is attached. [0003] However, if the small-diameter neck of the small-diameter opening side of the container is fitted with a cap locking neck on the small-diameter neck and then the small cap is installed, not only the top plate of the cap and the opening of the container cannot obtain sufficient locking force. There is a problem that a gap is generated between them, and complete sealing cannot be obtained, and there is also a problem that it takes effort to open and close, and it is troublesome to assemble and disassemble. [0004] In addition, it has b...
