Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging processing, in particular to a packaging box leakage prevention detection mechanism. Background Art
[0002] As the name suggests, a packaging box is a box used to package products. It can be classified by material, such as: paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, PVC boxes, etc. Inflatable packaging is to fill the packaging bag with a single gas such as nitrogen, carbon dioxide, oxygen, or a mixture of two or three gases after the packaging bag is vacuumed. The nitrogen is an inert gas and plays a filling role to keep the bag under positive pressure to prevent air from outside the bag from entering the bag, which plays a protective role for the food. Air leakage is an important factor affecting the food safety of inflatable packaging. When air, moisture and other impurities enter the packaging boxes and bags made of soft materials, bacteria are easily bred in the bag, causing the food to deteriorate quickly and the shelf life to be greatly shortened, causing a series of food safety problems.

[0004] In the prior art, the opening of the packaging bag is put into a vacuum pump and then the opening is tightened and fixed. However, the openings of the packaging bags are of different sizes. When the openings are tightened, gaps are easily generated, resulting in low air tightness. Therefore, we propose a packaging box leak detection mechanism. Utility Model Content
