Abstract

The invention discloses a vessel capable of releasing negative pressure automatically. The vessel comprises a container and a cup lid, wherein the cup lid comprises a top cover, a cover body and an inner cover; the top cover is in threaded connection with the top end of the cover body; the cover body is in threaded connection with the outer side of a container opening; the top surface of the cover body is sunken inwards to form an accommodating cavity; the upper end of the inner cover is connected with the cover body; the lower end of the inner cover extends into the container opening; a sealing ring is arranged in a clamping groove in the bottom end of the inner cover; the edge part of the bottom surface of the inner cover is sunken upwards to form a concave cavity; an air channel is arranged above the concave cavity; the air channel extends outwards, communicates with an inner side gap, and communicates with the atmosphere through a gap between the inner side and the outer side of the cover body; a pressure-release partition plate is arranged between the concave cavity and the air channel; and a one-way air inlet valve is clamped in a pressure-release hole of the pressure-release partition plate. According to the vessel capable of releasing negative pressure automatically, the cup lid is not tightly pressed on the opening and is easy to open; and owing to a simple negative-pressure release structure, not only are the production cost and the assembly time greatly saved, but also tableware contamination caused by the atmosphere can be avoided.

Description

technical field [0001] The invention relates to a vessel capable of automatically releasing internal negative pressure. The utensils may be soup boxes, water cups, food jars and the like. Background technique [0002] In life, we often encounter the trouble of not being able to open the lid of the container. This is because the pressure inside the container is lower than the atmospheric pressure, and the lid is pressed to death and the mouth of the container is closed. [0003] The invention patent with the patent number of 201310713472.7 discloses a "Pressure Relief Device for Insulated Container", which includes an insulated container 1, a container cover 2 connected to the insulated container 1 through threads, and the two sides of the container cover 2 are symmetrical on the cover edge A radial groove is provided, and a handle 3 can be horizontally rotatably clamped in the corresponding radial groove through the tongues 301 at both ends, and a seal 4 for sealing the pre...
