Metal materials surface decorative arts can good, high compressive strength, convenient to store and transport and other obvious characteristics, increasingly has suffered the love, metal bucket is used for packing food, start dates back to 200 before the Napoleonic era, now two pieces of metal materials, 3-piece cans had become soft drinks, fruit juice, your beer etc. One of the key way of packing. At this stage, many models and specifications of beverage cans are widely used on the market. Most of the covers are easy to open. However, the current standard adopts the easy to open structure types are flawed.

Eoe, commonly known as the pull down can cover, this kind of cover is convenient to open, open only the flap ring on the cat, a little strength to tear pull type can open the can cover. Buckle type easy to open the basic principle of opening is: first in the tank cover opened at the prefabricated stamping, reduce its part of the compressive strength, when opened in the buckle caused more centralized internal stress around the effect of shear stress, is cracked and opened at the stamping. In general, the external pressure difference in the tank is small, the shear stress caused by the imprint is small and well-proportioned, and the tank is not easy to split independently, which ensures the safety factor of canned goods in the delivery and SQL statement.

Easy pull cover

There are two ways to pull the lid: one is the opening type, the buckle is pulled up when the jar lid opens a small opening, so that the jar can suck out or pour out the liquid contents, the other is the open mouth type, the buckle is pulled up almost all the jar lid is opened, easy to remove the solid, powder or relatively high viscosity of the contents. The key to explore the opening of the lid, this kind of cover is widely used in beverage cans, at the present stage, the opening type easy to open the cover has two kinds: full tear type and part-time tear type. Both pot LIDS have their advantages and disadvantages.
