Plastic container with air pressure adjusting function

Abstract

The invention discloses a plastic container with an air pressure adjusting function, and belongs to the technical field of plastic containers, the plastic container with the air pressure adjusting function comprises a container body, and an air pressure adjusting part is arranged on the container body. Through the arrangement of the air pressure adjusting piece, when the air pressure in the container body is too large, the heat insulation piston plate can automatically slide to the other side of the air guide hole, air in the container body can flow into the air containing box through the air guide hole, and the elastic sealing film protrudes out of the air containing box to deform; therefore, the purpose of reducing the air pressure in the container body can be achieved, the container body is prevented from protruding, deforming or cracking due to the fact that the air pressure is too large, after the temperature is reduced, air flowing out of the container body can flow back, the container body is prevented from sinking inwards, and then the air pressure adjusting function is achieved. The container body can be effectively prevented from being damaged due to air pressure change, and therefore the service life of the container body can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of plastic containers, in particular to a plastic container with the function of air pressure adjustment. Background technique [0002] Plastic products are a general term for household and industrial products processed from plastic as the main raw material. Including plastic as raw material for injection molding, blister and other products of all processes. Plastic is a class of plastic synthetic polymer materials. Together with synthetic rubber and synthetic fibers, it forms the three major synthetic materials indispensable to daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, adding various additives, which can be molded into a certain shape under certain conditions such as temperature and pressure, and maintains the same shape at room temperature. [0003] Plastic container is one of the common plastic products in life, mainly used for storage, and t...

AI Technical Summary

Problems solved by technology

When the ambient temperature is too high or the temperature of the stored material is too high, the air pressure inside the container will be too high. At this time, the inner wall of the container will be subject to greater pressure, which will easily cause the plastic container to bulge, deform or even break. Although the plastic container can be installed with a pressure relief mechanism, such as a pressure relief valve, when the internal pressure of the container is too high, part of the air can be discharged through the pressure relief mechanism to achieve the purpose of reducing the air pressure, but when the temperature drops, due to the discharge Part of the air will cause the container to sag inward, and it is still easy to cause damage to the container
