Pneumatically installed container plug

Abstract

The invention belongs to the field of containers, and particularly relates to a pneumatically installed container plug. The pneumatically installed container plug comprises a container body and a plug main body, wherein a vacuum thermal insulating layer is arranged in the side wall of the container body, and the upper end of the container body contracts inwards in an arc-shaped mode and extends upwards to from a circular-tube-shaped container opening part with the diameter being less than the diameter of the container body; and the plug main body is composed of an outer plug body and an inner plug body, wherein the inner plug body is internally provided with a liquid channel, a drinking water opening is formed in the upper end of the inner plug body, a sealing cover is arranged on the drinking water opening, the lower part of the inner plug body is inserted into the container opening part, and the outer plug body sleeves the container opening part. According to the pneumatically installed container plug, no thread needs to be arranged on the plug of a vacuum cup, the plug can be rapidly installed on the container opening part through a pneumatic device, meanwhile, sealing of the vacuum cup is realized, the manufacturing difficulty and manufacturing cost are effectively reduced, no dead angle is generated, and the cleaning difficulty is reduced.

Description

technical field [0001] The invention belongs to the field of containers, and in particular relates to a pneumatically installed container stopper. Background technique [0002] Existing container embolism, known have the embolism that drinking water mouth, seal cap and plug body are a whole, and such embolism is mostly installed in container mouth by screwing, and like this just needs to be installed in container mouth and embolism respectively. The female thread and the male thread are arranged on the top, and the setting of the female thread and the male thread makes the manufacture of the thermos cup complicated and increases the manufacturing cost of the thermos cup. The female thread and the male thread will also form multiple dead angles on the mouth of the container and the plug , It is more difficult to clean. [0003] Aiming at the problem that various positions of the plug cannot be effectively cleaned, there is a known structure that decomposes the plug into a pl...

AI Technical Summary

Problems solved by technology

In the existing patent application number 201210087163.9, the plug body that can be freely loaded and disassembled at the mouth of the container body is decomposed into an inner plug part and an outer plug part, and the connection between the inner plug body and the outer plug body is realized by buckling. The structure enables all parts of the embolism to be effectively cleaned after decomposition, but this structure also complicates the overall structure of the embolism, increases the manufacturing cost of the embolism, and also makes the embolism form multiple dead ends, increasing the difficulty of cleaning the embolism
