Description

The present invention relates to a beverage container such as a pitcher that can be stored in a door box of a refrigerator and cooled in a state where a beverage such as water or tea is contained.

In general, in a pitcher as a beverage container, a lid that closes the central opening of the pitcher body having a large diameter is simply inserted into the central opening from above so that insects and dust do not enter from the central opening of the pitcher body. It was just a thing.
However, if the lid is only inserted, if the pitcher body is tilted when pouring into a cup or the like, the lid may also be tilted and come off at the same time.

Therefore, in order to avoid detachment of the lid, a female screw is engraved on the inner peripheral wall forming the central opening of the pitcher body, and the male screw to be screwed to the female screw is formed in two layers on the outer peripheral wall of the lid. Japanese Patent Application Laid-Open No. 2011-56254 discloses a pitcher serving as a beverage container having a structure in which it is rotated as an all-around screw of three layers and a lid is firmly screwed into the central opening of the pitcher body.

JP 2011-56254 A (see FIGS. 1 and 3)

However, in such a pitcher as a beverage container, even if the female screw 222 engraved on the inner peripheral wall forming the central opening of the pitcher body is not a full screw, but a partial screw, the female screw 222 is threaded. Since the male screw 308 on the lid side to be worn is an all-around screw having multiple layers, when the lid is screwed into the central opening of the pitcher body, the lid must be rotated many times. In addition, it is difficult to easily grasp the first screwing position of the female screw on the pitcher body side and the male screw on the lid side, and the lid body cannot be easily and smoothly operated even though there is no risk of the lid body coming off. was there.

In particular, for the elderly and others to use, if the initial engagement between the pitcher body side and the lid body side does not go smoothly, the lid body will be inserted into the pitcher body side at an angle by forcibly fitting. Next, when removing the lid, there was a problem that the screw engagement was out of order and the lid could not be removed.
In addition, for elderly people, it is troublesome to turn and screw the lid on the pitcher body over and over again. was there.
