Description
Technical field
The present invention relates to food packaging applications, and in particular to a kind of food cans lid and food cans.
Background technology
Food cans are commonly used for the packaging for foodstuff that can, milk powder etc. need to preserve for a long time, the sealing property of food cans and
Structural strength determines preservation quality of the food during storage and transport.The structure of food cans generally includes tank body and tank
Lid, tank body is processed respectively with cover, and is finally fastened.The passage that takes food of food is typically preset on cover, facilitates making for user
With.
Publication No. CN 201834291U Chinese utility model patent discloses a kind of packing box of convenient food, sealing
Lid is provided with annular indentation, and is scored in lid in the region enclosed provided with draw ring.When edible, it is only necessary to pull draw ring,
The region that indentation on lid can be surrounded is separated from lid, forms the opening taken food, and this tank body is easy to use, and is preserved
Good airproof performance.But, after switching, the edge at opening is very sharp for lid, there is easy scratch during user takes food
The problem of hand, have a strong impact on performance.
For said structure presence the problem of easily scraping hand, in the market occurs in that a kind of food cans of flip-cover type, i.e., by tank
Lid is divided into lid and flip, and the centre of lid is provided with opening, and described flip is directly fastened at opening with lid, and at opening
Edge fold inward, prevent from scraping hand.Although this structure solves the problem of easily scraping hand, but is fastened between flip and lid
The sealing property of structure is poor, and the long-time for being difficult to realize food is preserved.Publication No. CN 201856969U China is practical
New patent discloses a kind of safe compound cover, and aluminium foil is laid in the bottom of above-mentioned cover-lift structure, in the storage and transport of food
During, aluminium foil can realize the sealing of food well.But, because the structure needs to tear on aluminium foil before food is taken food
Broken, aluminium foil fragment is likely to enter food, so as to influence edible safety；Moreover, the combining structure increase of flip and aluminium foil
The complexity of structure, the production cost of food cans is higher, after being opened especially for can and convenient food etc. in the short time
The food eaten, the repeatedly unlatching closure function of cover-lift structure is not fully utilized on the contrary.
