Quick sealing type food bag and using method thereof

Abstract

The invention discloses a quick sealing type food bag and a using method thereof, and belongs to the field of food bags. According to the quick sealing type food bag and the using method thereof, through a long pressing rod and a short pressing rod arranged at the edges of the two sides of a bag opening, the bag opening can be turned and folded; the bag opening is turned repeatedly and folded, andthe connectivity with the outside is blocked many times, so that the sealing effect is better; at the same time, under the matching action of an embedded locking rod and an attraction magnet, the turned and folded bag opening can be fixed; in combination with the action of pressing and adhering contacts, the sealing performance and stability after sealing can be effectively improved, the probability of accidental opening of the bag opening can be reduced, and the time for finding a tool to seal the bag opening can be effectively reduced; and meanwhile, compared with clamping sealing, the positioning difficulty and the too much operation time are effectively avoided, and the convenience and the operation efficiency for sealing the packaging bags are effectively improved.

Description

technical field [0001] The invention relates to the field of food bags, more specifically, to a quick-sealing food bag and a use method thereof. Background technique [0002] Food packaging bags are a kind of packaging design. In order to keep fresh and store food in daily life, product packaging bags are produced.

AI Technical Summary

Problems solved by technology

[0005] After the food packaging bag is unpacked, when the food in the packaging bag is taken out, it often needs to be sealed. Many existing food packaging bags do not have the function of secondary sealing. Twist and twist together, but the sealing effect is poor, or use other tools, such as clips, to clamp the bag mouth, but you need to look for clips everywhere, which is inconvenient to use. Generally, it has a sealing function, usually snap-fit ​​seal, snap-fit ​​seal It can be reused many times. After taking the food, snap them together again and still have a sealing effect. However, this method needs to be aligned and snapped, but there are often parts of the snap-fit ​​that fail to snap together normally, resulting in Air leakage shortens the storage time of the food inside and is easily contaminated
