Plug for beverage container

Abstract

PROBLEM TO BE SOLVED: To secure the locking / unlocking operation of a cover, and to surely recognize a locking / unlocking state to be identified. SOLUTION: This plug 3 includes a ring member 20 having a center opening 22 around a center axis 10 penetrating in the vertical direction, and a hinge 23 at one end connected to a hinge receiving portion 16 so as to be turnable, and a rotary member 21 which is mounted to an inside opening 20A of the ring member 20 so as to be turnable and on the side face of which a second male screw 30 as a locking protrusion is disposed. A hinge shaft hole 39 is formed in an oblong hole shape longer in the direction of the center axis 10 during closing the cover. The locking / unlocking state of the cover 4 to be identified can be confirmed in viewing the ring member 20 at its upper end position projected / exposed with the ring member 20 moved forward and backward in the vertical direction.

Description

technical field [0001] The present invention relates to a plug body for a beverage container. Background technique [0002] In the past, as a plug body for such a beverage container, the following technology is known: a cover ring for opening and closing the container opening is hingedly supported on the container body, and a cover ring is provided on the inside of the cover ring to be threadedly engaged with the opening of the container body to open and close the cover. Rotary cover (for example, Patent Document 1, etc.). In addition, the cover covering the flow channel is attached and detached by screw fitting (for example, patent document 2, etc.); the cover and the plug body are connected by a connecting member (for example, patent document 3, etc.); Drinking and pouring operations can be performed with the cap attached without detaching and attaching the cap (for example, Patent Document 4, etc.). The cover covering the pouring spout or the drinking port and the flow ...

AI Technical Summary

Problems solved by technology

[0011] As for the screw cap and the hinge shaft rotating integrated plug body of Patent Document 1, since it does not belong to the pouring and drinking plug structure, it is difficult to recognize the direction of the front, or when viewed from above, it is difficult to recognize the locking and locking of the cap. Fixed release, that is, the cover is advancing and retreating in a certain direction up and down

[0012] With regard to the cap-separated type of the threaded cap of Patent Document 2, since the removed cap needs to be held in the hand or placed on the table, it is not easy to attach and detach.

On the other hand, with regard to the plug body in which the cover of Patent Document 2 is connected to the plug body through a relatively long connecting member, when the container is tilted to drink, the drooping cover will hinder drinking and sometimes fall on the forehead, etc. In addition, Since the position and direction can change freely when it is removed, it is not easy to align the thread positions one by one during installation.

Moreover, for the plug body that rotates halfway and produces a channel gap like Patent Document 4, it is difficult to recognize the outflow of the beverage, that is, the change of flow rate, speed, and liquid level, because the flow channel of the drinking port will not be completely opened. Because it is difficult to control, the desired amount will not flow out, or an excessive amount will flow out, which is not convenient and may cause burns

[0013] In addition, for the one-touch (one-touch and open) plug body of Patent Document 5, a button and a locking member for locking the cover, and a spring member for energizing the cover or the button are required, and the structure is complicated, and the assembly performance is low. There are problems in product cost, cleanability, etc., and if the locking protrusions of the button and the locking member are arranged on the top or front of the plug body, the drinking operation, carrying, and storage are hindered, and the protrusions may be damaged after being dropped, or Inconvenient situations such as hooking in the bag, and when the cover is turned with spring force given by the spring member, the water droplets attached to the water-stop seal of the cover when it is suddenly opened splashes and stains the surroundings, or it may be caused by the sudden movement of the cover. open to be frightened

[0014] In addition, for the manual cover type plug body of Patent Document 6, because it belongs to the non-water-stop or simple water-stop structure mainly used on the desktop, the structure for locking the cover in the closed state does not exist or is insufficient, so there is a problem of carrying When the lid is opened when it is dropped or when it is dropped, the beverage will leak out

[0015] And, for the plug body of the manual liquid injection hole handle rotation type of patent document 7, since the container opening and the liquid flow channel will not all be opened when drinking, it is difficult to recognize the outflow of the beverage and it is difficult to control it, so it will not flow out. Desired amount, or excessive flow out, not convenient, and may cause burns

In addition, since the liquid flow path is not fully opened, the cleaning performance is poor and unhygienic
