Description

Food can capable of being quickly unsealed and preventing sealing and cutting

Technical Field

The invention relates to the field of food cans, in particular to a food can capable of being quickly unsealed and preventing a seal from being cut.

Background

The food raw materials are pretreated (including cleaning, removing inedible parts, cutting, inspecting, trimming, etc.), precooked, seasoned or directly canned, added with seasoning liquid or additive-free (dry packaging), exhausted, sealed, sterilized, cooled, etc., and finally the can processing is completed. The pretreatment, seasoning processing and the like are different according to different raw materials and product types, but the processes of exhausting, sealing, sterilizing and cooling are necessary procedures, and the processes are basic production processes of can processing. Because the canned food is preserved for a long period of time by means of sterilization, and the preservative is not used for the purpose of preserving the food by inhibiting spoilage microorganisms. Therefore, metal empty cans, glass bottle cans, plastic containers and the like for sealed packaging are necessary conditions for can processing.

Some current metal food cans such as oatmeal can, eight treasures congee can and milk powder can etc. tear the in-process that the sealing connection membrane that will have the pull ring tears, it is great to tear required dynamics, and be difficult for tearing, tear the sealing connection membrane for more effective, some users can hold jar edge with the hand carelessly, and the easy mistake is touched the sealing of being close to jar edge department, the sealing has the cutting edge and cuts the user's hand easily, some food users can stretch into the hand in addition and take out food, take the in-process of food, the hand stretches into jar internal content and easily mistake touches the seal and is cut, edible security is lower.
