Food can capable of preventing cutting of sealing edge surface

Abstract

The invention discloses a food can capable of preventing cutting of a sealing edge surface, and belongs to the field of food cans. The food can capable of preventing cutting of the sealing edge surface comprises a can body, a convex part, a sealing film structure, a pull ring, an annular sealing part and an upper connecting part, wherein the convex part is fixedly arranged at the upper end of thecan body; the upper connecting part is fixedly arranged at the upper end of the convex part; a concave surface is arranged on the inner side of the convex part; the annular sealing part is fixedly arranged on the concave surface; the inner diameters of the can body and the upper connecting part are both smaller than the inner diameter of the annular sealing part; the outer side edge part of the sealing film structure is in tearing connection with the inner wall of the annular sealing part; the sealing film structure is deformed under the pulling effect of external force, and the deformation quantity is increased step by step, so that when hands of operators extend into the can body to take contained objects or extend out of the can body, the hands are not easy to cut by the edge surface ofthe annular sealing part, and the use safety is higher; and meanwhile, through special structure setting of the sealing film structure, the convex part is not easy to hinder taking of the sealing film structure out of the can body.

Description

technical field [0001] The invention relates to the field of food cans, more specifically, to a food can that prevents cuts on the sealing blade surface. Background technique [0002] Food raw materials are pre-treated (including cleaning, removal of non-edible parts, cutting, checking, trimming, etc.), pre-cooked, seasoned or directly filled in cans, seasoned liquid or without addition (dry packaging), exhaust, sealing and sterilization, Cooling and other processes, and finally complete the canning process. Among them, pretreatment and seasoning processing vary with different raw materials and product types, but exhaust, sealing and sterilization, and cooling are necessary processes, which are the basic production processes of canning. Because canned food is preserved for a long time by sterilization, rather than using preservatives to suppress spoilage microorganisms to preserve food. Therefore, containers such as metal empty cans, glass bottles and cans, and plastics us...

AI Technical Summary

Problems solved by technology

[0003] Some existing metal food cans, such as cereal cans, eight-treasure porridge cans, and milk powder cans, etc., in the process of tearing the sealing film with the pull ring, in order to tear the sealing film more effectively, some users will accidentally pull their hands. Holding the rim of the can, it is easy to accidentally touch the sealing part near the rim of the tank. The sealing part has a blade surface that is easy to cut the user's hand. In addition, some food users will reach in and take out the food. During the process of taking food, It is easy to touch the seal by mistake and get cut when you put your hand into the tank, which is less safe to use
