Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] One-way exhaust decompression plastic bottle inner cover is characterized in that a one-way exhaust device is set in the middle of the inner cover 1, and the one-way exhaust device is provided with an exhaust pipe 2 in the middle of the inner cover 1, and the exhaust pipe 2. The shape on the inner cover is an exhaust pile, and the exhaust pipe 2 is integrally formed with the inner cover 1. The elastic seal 3 is a soft rubber hose, the exhaust pile is socketed with the soft rubber hose, and the upper mouth 4 of the exhaust pipe 2 is sealed by the soft rubber hose, and the lower mouth 5 of the exhaust pipe is connected to the lower chamber of the plastic bottle. When the air pressure in the bottle rose, the high-pressure gas broke through the pressure of the soft rubber hose through the exhaust pipe 2 and flowed to the top of the bottle.

Abstract

The invention provides an inner cover of a one-way exhaust decompression plastic bottle installed on an opening part of a plastic bottle, and the inner cover is used for solving the technical problem that air pressure in a bottle body rises and cannot be released. The inner cover of the one-way exhaust decompression plastic bottle is characterized in that a one-way exhauster is arranged at the middle part of an inner cover body (1), and the one-way exhauster is as follows: an exhaust pipe (2) is arranged at the middle part of the inner cover; an elastic sealing element (3) blocks an upper opening part (4) of the exhaust pipe, and a lower opening part (5) of the exhaust pipe is communicated with the lower cavity of the plastic bottle. The inner cover of the one-way exhaust decompression plastic bottle can be used for effectively preventing from dangerous accident of cracking caused by over-high air pressure in the bottle body, and preventing external air from entering the bottle body to pollute the food, so as to ensure the food health..

Description

technical field [0001] The invention relates to a food packaging container assembly, in particular to an inner cap of a plastic bottle used for holding food. Background technique [0002] When packaging food in ordinary plastic containers, in order to avoid food deterioration and external contamination in the bottle, tinfoil paper is usually used to seal the mouth of the bottle, and the mouth of the bottle is tightly sealed with a threaded outer cover. The technology of sealing the mouth of the bottle with tin foil paper has potential safety hazards. When the food is placed in this plastic container, the temperature is above 30 degrees, and the fermentation of the food in the bottle will generate a large amount of gas in the bottle, causing the air pressure in the bottle to rise. If the air pressure in the bottle is not released in time, the plastic bottle container is easy to burst. The bottle body bursts to form jets, which may pollute the environment if it is mild, or ma...
