Description

Lid

Technical field

The utility model relates to a kind of seal that is used to become the container of splendid attire food, specifically adorn food bottle, jar lid.

Background technology

Bottled, the canned food of selling on the market is a feast for the eyes, these commodity all seal after sterilization for the ease of storage, transportation, these lids are the lid of pure sealing function structure the earliest, all to could open lid in people's long-term use with great strength and special instrument, therefore all sensation inconvenience like this, impels makers to design later-model lid, this lid has not only kept is convenient to the function of storing, transporting, and is convenient to open.The easy-open lid that this lid particularly generally uses on Cans now.Such as Chinese patent ZL96247422.3, a kind of pop can skull, this lid on its top surrounds ring-band shape by the twice groove, and the top of endless belt is being fixed one with rivet and is being opened handle, during use, applies a pressure by prizing handle, can open whole lid.The present Beverages and Canned Food of mass selling on the market, the food canned eight treasure porridge, even " cold tea " can that has a place, Guangdong of health care purpose has also all adopted the lid of this pattern principle.Though this lid has realized being convenient to storage, transportation, guarantee food quality and easy-open end labour-saving purpose again, but all to fix a draw ring with rivet at the circular groove of caping place, or unlatching handle, so just must increase the investment of equipment such as tapping machine, increase operation simultaneously, increased employed material, caused cost to increase; The pecker that is tapping machine on the other hand is built-in with " rivet ", when the pecker on the tapping machine is bored a hole caping rivet is placed the hole.Must seal could be air tight slit place between rivet and the caping, could guarantee that like this food never degenerates in the jar, we know the circumference in the tank deck hole in the cold machine up be impossible rivet is fixedly sealed to airtight, the pecker work initial stage that is to say tapping machine like this is cold, the lid of producing is certain to gas leakage and becomes waste product, has only pecker repeatedly after caping perforation extruding friction produces certain heat, just can make circular hole that caping is worn that certain heat has been arranged and expand, temperature descends that the back fixes its rivet by its contraction and to rivet and the sealing in slit between caping hole circle week by the time.Tapping machine is because of high efficiency, and pecker moves back and forth soon, but just Chuan Gai hole more than 2000 was individual in one minute, and these these more than 2000 lids that is to say tapping machine work initial stage manufacturing can become waste product, have caused certain waste.

Summary of the invention

The purpose of this utility model provides a kind of lid, and this lid guarantees that food never degenerates, and easily opens, particularly low the and no waste product of cost.

Technical solution of the present utility model is finished like this, lid, caping at existing known technology seal on the basis of bottleneck U-shaped circular groove, the utility model particularly at caping envelope bottleneck U-shaped circumferential groove outer bottom, carve and cut an imperforate circular groove by suitable its bottom land circumference.

The above inboard place of caping envelope bottleneck U-shaped circumferential groove outer bottom, suitable its bottom land circumference is carved and has been cut an imperforate circular groove.

The utility model principle of work is, only need take the corresponding any hard object that is not more than caping envelope bottleneck U-lag width when uncapping, such as, the head or tail of soupspoon, key, the fork that metal sheet, western-style food are used, cutter or the like, be placed in the groove, hold its other end slightly firmly press down can tearing groove at the bottom of on circular groove, and the part in the caping U-shaped circumferential groove is pried open, i.e. edible.Because the utility model is not provided with draw ring on caping, promptly do not open handle, has just removed the investment of tapping machine from yet, and has reduced operation, has saved the energy, has reduced cost, the waste of yet having avoided tapping machine inevitably to make waste product at the work initial stage.

The utility model has the advantages that this lid guarantees that food never degenerates, easily open, particularly low the and no waste product of cost.
