Description

Technical Field

[0001] The invention relates to a container structure, in particular to a container plug cover. Background Art

[0002] A container in the prior art includes an outer cover arranged outside the container mouth and a plug cover plugging the container mouth. The outer cover can be used as a water cup when in use. Therefore, when in use, after removing the outer cover, it is necessary to open the plug cover to pour out the liquid in the container, which is quite troublesome.

[0003] In order to solve the above problems, Chinese utility model patent CN 211380959U discloses a thermos pot, wherein a pot stopper is used to block the pot mouth, and the pot stopper includes a body, a knob, a cover, a cam mechanism and a temperature display module; the body is provided with a flow channel, the knob is provided at one end of the body, and the cover is provided at the other end of the body; the cover can reciprocate along the axial direction of the body to open or close the flow channel; the cam mechanism is provided in the body and connects the cover and the knob, and when the knob is rotated, the cover can be pushed by the cam mechanism to reciprocate along the axial direction of the body, and the temperature display module is provided on the body for detecting and displaying the temperature. The cam mechanism includes an active cam connected to the knob, a passive cam connected to the cover, and an elastic member that pushes the passive cam to reset, the active cam is provided with a wavy push surface, and the passive cam is provided with a wavy contact surface adapted to the wavy push surface.

[0004] This technical solution sets a liquid flow channel on the plug cover, and uses an active cam and a passive cam to control the cover to open or close the liquid flow channel, so that the liquid can be poured out of the container without pulling out the plug cover. However, this solution sets a knob and a cam structure to cooperate, and the user cannot distinguish when the cover is opened and when the cover is closed, and often makes mistakes, thinking that the cover is closed. As a result, when the outer cover is opened again, the liquid in the container has overflowed. In addition, in this technical solution, a reset spring must be provided, otherwise the cam structure cannot achieve its function of controlling the cover, which means that once there is a problem with the spring, the plug cover may not be able to close the liquid flow channel.
