Problems solved by technology

[0003] Vacuum packaging currently used includes vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastic and its composite material packaging, etc. Vacuum packaging in clinker bags or aluminum foil packaging is usually disposable packaging and cannot be recycled; glassware, Plastic and its composite material packaging can realize the recycling of containers, but because the container is in a highly decompressed state after being evacuated, the pressure difference between the inside and outside of the container makes it difficult to open the container
Moreover, the storage tanks currently on the market have complex structures, high cost, no decompression effect or insignificant decompression effect, insufficient pressure holding time, and serious air leakage. These problems lead to low product popularity.

Embodiment 1

[0039] When performing air extraction work, take the air extraction device 9 and insert it into the sealing air nozzle from the air hole 31' of the button 3', the air extraction device 9 will press down the sealing assembly, and the piston sealing ring 71' and the cylindrical air guide hole of the sealing bracket 4' A gap is formed between 42'. At this time, the inner cavity of the container, the gap between the inner wall of the valve bottom cover 5' and the outer wall of the valve installation port 21', the ventilation square groove 41' of the sealing bracket 4, and the piston sealing ring The gap between 71' and the cylindrical air guide hole 42' of the sealing bracket 4' forms an air path, through which the air in the container is drawn out by the air extraction device, and a highly decompressed environment is formed in the container.

Embodiment 2

[0041]When performing deflation work, press the button 3" down, the button 3" will press down the sealing assembly, and a gap will be formed between the piston sealing ring 71" and the cylinder air guide hole 42" of the sealing bracket 4", at this time, the button 3" air hole 31", air hole 31" at the bottom of the circular groove 311", the gap between the piston sealing ring 71" and the cylindrical air hole 42" of the sealing bracket 4", the ventilation square groove 41" of the sealing bracket 4", the air The gap between the inner wall of the nozzle bottom cover 5" and the outer wall of the air nozzle installation port 21" forms an air path, and the external air enters the container through the air path to balance the internal and external air pressure, and the container cover 2" can be easily opened.

Abstract

The invention discloses a vacuum air pumping and deflating container. The vacuum air pumping and deflating container comprises a container body and a container cover which covers the container body; the container cover is matched with the container body in an air-tight manner; an air cock assembly opening is formed in the center of the top of the container cover; a button which is slidably matchedwith the air cock assembly opening is sleeved in the air cock assembly opening; a through air hole is formed in the center of the button; a sealing air cock is arranged in the air cock assembly opening; the sealing air cock comprises a sealing support and an air cock bottom cover; the sealing support sleeves the air cock assembly opening; the inner wall of a cylindrical air guiding hole sleeves asealing component which is slidably matched with the cylindrical air guiding hole; a spring is connected between the bottom of the sealing component and the inner bottom surface of the air cock bottom cover; the sealing component ejects the sealing support to be matched with the air cock assembly opening in an air-tight manner; air pumping and deflating of the container are facilitated while ensuring the recycling of the container; the decompressing effect of the device is stable; the pressure maintaining time is reliable and long; and more excellent storage packing experience is provided forusers.

Description

technical field [0001] The invention relates to the technical field of vacuum packaging, in particular to a container for vacuum pumping and degassing. Background technique [0002] Vacuum packaging, also known as decompression packaging, is to extract and seal the air in the packaging container to maintain a high degree of decompression in the bag. The scarcity of air is equivalent to the effect of low oxygen, so that microorganisms have no living conditions, so that the preserved items are fresh and disease-free. purpose of corruption. [0003] Vacuum packaging currently used includes vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastic and its composite material packaging, etc. Vacuum packaging in clinker bags or aluminum foil packaging is usually disposable packaging and cannot be recycled; glassware, Plastic and its composite material packaging can realize the recycling of containers, but because the container is in a highly decompressed state ...
