Description

Technical Field

[0001] This utility model relates to the field of food preservation bags, and in particular to a vacuum food preservation bag with a valve structure. Background Technology

[0002] The main function of food storage bags is to extend the storage time of fruits and vegetables by inhibiting their respiration. When a food storage bag seals fruits or vegetables, the oxygen content inside decreases and the carbon dioxide content increases, thereby inhibiting respiration, reducing the decomposition of organic matter, and thus extending their shelf life. Food storage bags are typically made of materials such as polyethylene (PE), polyvinyl chloride (PVC), and polyvinylidene chloride (PVDC). Different materials are suitable for different uses. For example, PE bags are suitable for storing vegetables, fruits, grains, and cooked food. Environmentally friendly food storage bags use fully biodegradable materials, which are not only environmentally friendly but also have antibacterial properties, making them suitable for various uses such as preserving fruits and vegetables, carrying food, and packaging cooked food. It is important to note that PVC food storage bags should not be used directly for packaging cooked food, as PVC may release harmful substances at high temperatures. Therefore, choosing the right food storage bag material is crucial for ensuring food safety and extending food shelf life.

[0003] Currently, most vacuum food storage bags require a significant amount of time and effort to remove the air, reducing the oxygen content inside and making them very inconvenient to use. To address this issue, we propose a vacuum food storage bag with a valve structure. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, consisting of an inner preservation bag, an outer protective bag, a first one-way valve, a second one-way valve, a first threaded tube, a second threaded tube, a first sealing gasket, a second sealing gasket, a vent, and a vent threaded tube, uses the first one-way valve in conjunction with the first threaded tube and the first sealing gasket to extract oxygen from the inner preservation bag. Simultaneously, it uses the second one-way valve in conjunction with the second threaded tube and the second sealing gasket to extract oxygen from the outer protective bag. Finally, it seals the outer protective bag through the vent and the vent threaded tube.
