Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handy type liquid container, and more specifically, to its stopper opening/closing structure.

Conventionally, in this type of liquid container, the opening of the liquid container is opened and closed by the screw rotation of a screw-type column, but while the screw-type column has an excellent sealing effect when closing the cap, it is troublesome to open and close the cap. However, there was a problem in that it could not be done with one touch.

In view of the above-mentioned problems, the present invention provides a screw-type column with a core frame for opening and closing the liquid container opening, and allows the core frame to be operated from the outside with a single touch, thereby improving the sealing effect of the screw-type column. The purpose of this is to provide a cap opening/closing structure that combines the operability of a one-touch closure, and to achieve this purpose, it is constructed of the upper part of the container body, with a handle at the rear and a lower part at the top. In a liquid container in which a screw-type column is removably screwed into a stopper insertion hole of a lower mouth member each having a mouth cover, the stopper has an opening that communicates with the liquid container in the container body to open and close. A core frame is provided to be able to move up and down, and an external operating lever of an operating mechanism that operates to move the core frame up and down is provided on the upper part of the handle so as to be slidable back and forth. teeth,
It is characterized by a structure in which a lever cover is integrally provided to cover the external operating lever so as to slide and guide the external operating lever between the upper surface of the handle and the upper surface of the handle.
