Description

Spinning seal pot

Technical Field

The utility model relates to a novel packaging container, in particular to a spinning sealing tank.

Background

In the prior art, the tea is stored and packaged by adopting an iron pot, and the cover and the pot body can be matched tightly, so that the cover is not easy to separate from the pot body, and the tightness is good. However, as consumer ideas increase, industry packaging is increasingly being performed with paper cans. The stamping of paper cans is typically made of metal, plastic or bamboo. Because of the relatively soft material of the can, the cap is relatively difficult to mate with the can, and in order to achieve the sealing effect, the mouth of the can is generally snapped into the recess of the cap by means of an internal bayonet.

However, the tightness of the connection between the cover and the can body is not reliable, especially, the can body such as a paper can body or a paper-plastic composite can body, which has poor self material strength or poor elasticity, has a poor sealing effect due to elastic fatigue after the upper cover is opened and closed for many times.

In order to solve the above-mentioned shortcomings of similar products in the market, the applicant has invented a multi-seal packaging can, such as chinese patent CN202121909969.2. As shown in fig. 1, the multiple sealing packaging can utilizes the multiple sealing structure between the upper cover and the middle cover, so that the removable sealing connection of the packaging can be ensured, and the disposable anti-theft sealing is carried out through the easy-tearing film, thereby achieving the multiple sealing packaging effect. The multiple sealing packaging can is particularly suitable for the cans with poor self material strength or poor elasticity, such as paper cans or paper-plastic composite cans, and can ensure that the upper cover can have reliable sealing effect after being opened and closed for many times. The applicant has brought the multi-seal packaging can to market, obtaining a very good reverberation.

However, as the sales of the product increases, the application of the product is increasingly wide, the use of the product is more and more, and some problems which are not expected originally are also followed, such as the problem of tightness. Because the sealing of jar relies on jar body oral area to a great extent to compress tightly the upper cover sealing washer and forms, and still one deck easily tears the membrane between jar body oral area and the upper cover sealing washer when packing, has certain space after tearing easily tearing the membrane between jar body oral area and the upper cover sealing washer, and then influences jar holistic leakproofness. The problem is more obvious when the elasticity of the upper cover sealing ring is reduced after the use times are increased, and particularly, the problem is more remarkable when the tank body is further provided with the inserting groove, because the bottom of the inserting groove prevents the upper cover from further downwards, so that the space between the opening of the tank body and the upper cover sealing ring cannot be compensated.
