Plug body for beverage container

Abstract

PROBLEM TO BE SOLVED: To provide a stopper body of a drink container having a lock mechanism, whose operability and visibility for discrimination between a lock state and an unlock state are improved. SOLUTION: A stopper 4 includes the stopper body 8 and a lid member 7. The stopper body 8 includes a button 21 which is prepared on a front part 8F of the stopper body 8 and has, at its upper part, an engaging part 24 for engaging with an engaged piece 14 of the lid body 7. The button 21 is pivotally supported to the front part 8F so as to be able to advance / recede toward / from the stopper body 8. A slide type stop member 22 is vertically slidably prepared on a part of an outer peripheral wall of the stopper body 8 below the button 21, wherein a stop piece 33 is set at a back side of the button 21 in non-contact state on a steady basis. In this position state, the slide type stop member 22 inhibits movement of the button 21 in the direction of releasing the engagement by inserting the stop piece 33 in the back side of the button 21. The slide type stop member 22 has sideway parts 42 extending right and left of the stop piece 33 and a lengthwise part 43 extending vertically from the stop piece which are formed integrally with the stop piece 33. Operation parts 45, 46, 48, 49, 51 are formed on the extended parts of the slide type stop member 22 so that the operability and visibility are improved.

AI Technical Summary

Problems solved by technology

For example, for right-handed people, locking on the left is not easy to operate

[0024] The lock is installed on the cover to control the rotation of the lock button. When closing the cover, it is easy to cause misoperation by pressing the lock by mistake so that the cover is not locked.

[0025] As described in Patent Document 10, the lock knob is installed on the cover and controls the rotation of the lock knob where the lock is installed and locked. It is difficult to visually distinguish the ON / OFF state of the lock from the front. The solid operation part is separated, and the continuity of the lock button operation and the lock operation is not good

In addition, since the lock button is installed on the cover body, it is necessary to press the lock button and then lift the cover when opening the cover body, so it cannot be fully opened with one touch

In addition, the locking operation part protrudes outward from the cover body, which may easily cause it to fall and cause the locking to be damaged.
