Sealing method for container

Abstract

The invention provides a sealing method for a container. The sealing method comprises the following steps: manufacturing a ring-shaped sealing sleeve adaptive to the periphery of a bottle body by adopting a rubber material which expands with heat and contracts with cold; arranging a ring of ring-shaped stripes capable of being torn in the middle of a ring-shaped outer sleeve; heating the ring-shaped sealing sleeve, and then arranging the heated ring-shaped sealing sleeve at the periphery of the bottle body and at the periphery of a bottle cover in a sleeving mode; and arranging the ring-shaped stripes at an intersection position of the bottle body and the bottle cover. According to the sealing method, an outer cover re-sealing mode is adopted, so that the outer cover is very easy to open, and therefore, anti-theft and anti-fake purposes can be achieved, and quality guarantee time of products in a bottle can be prolonged. After the ring-shaped stripes are torn, the ring-shaped sealing sleeve is changed into two sections which are respectively arranged on the bottle body and the bottle cover in the sleeving mode, so that the container is protected; and meanwhile, the container, which is made of a plastic or elastic material, is convenient for a consumer to hold.

Description

technical field [0001] The invention relates to the technical field of container packaging, in particular to a container sealing method. Background technique [0002] In the field of cosmetics, the sealing of cosmetic bottles is a very important technical link. The sealing of existing cosmetic bottles all adopts an inner sealing method, that is, the outer cover adopts an openable method, and tin foil or aluminum foil is used to seal the cosmetic outlet, but this sealing method is also easy to be damaged. [0003] In the field of food packaging, such as the current cooking oil, there is a tearable disc inside the bottle mouth, and a tearable ring on the bottle cap, but the ring and the bottle cap are integrated structure, which is threaded The way of connection goes up. After tearing off the ring, the upper part is completely a bottle cap; in the oral liquid package or freeze-dried package, the sealed package with the outer buckle is usually pressed with aluminum material, w...

AI Technical Summary

Problems solved by technology

Existing cosmetic bottles are sealed in the way of internal sealing, that is, the outer cover is openable, and the cosmetic outlet is sealed with tin foil or aluminum foil, but this sealing method is also easily damaged

[0003] In the field of food packaging, such as the current cooking oil, there is a tearable disc inside the bottle mouth, and a tearable ring on the bottle cap, but the ring and the bottle cap are integrated structure, which is threaded The way of connection goes up. After tearing off the ring, the upper part is completely a bottle cap; in the oral liquid package or freeze-dried package, the sealed package with the outer buckle is usually pressed with aluminum material, which is not easy to open. After the material is pried open, it becomes a waste product without any other function

[0004] Nutrients are added to many existing cosmetics. If the seal is not done well, these nutrients will become a breeding ground for cell growth, making the cosmetics become a source of skin allergies in the hands of consumers, not only can not make the skin get better Nourishing, but allergies and sores, causing bad effects on consumers

At the time of sale, many cosmetic bottles are placed side by side. Some consumers may try to open the bottle out of curiosity to try the product, and then cover it again, causing the real buyer to buy the opened product. , the result of this is that buyers have doubts about the reputation and product quality of producers and sellers
