Description

A tank sealing cover structure

technical field

The utility model relates to a tank body, in particular to a tank body sealing cover structure.

Background technique

In the prior art, most of the packaging cans used for packaging food are metal cans. The metal cans are usually provided with an outer cover and a sealing layer. , Cause the secondary sealing difficulty of metal outer cover and tank body, both be inconvenient to the storage of food for a long time, be inconvenient to take food again and again of food. For milk powder, the amount of each time is small, and each can is used for a long time, which puts forward higher requirements for the sealing of the packaging cans. At present, iron cans are generally used in the market, and the sealing forms of the can lids are mostly. Among them, the clamping extrusion seal is adopted, the fit is tighter, and the sealing effect is better, but the disadvantage of this type of tank cover is that it is troublesome to open the cover, and it is often necessary to use other tools such as scissors to pry it up, which cannot achieve the effect of convenient use. Frequent prying is easy to deform the tank cover and cannot be tightly combined with the tank body, weakening the sealing effect. There is also a sealing structure, such as a tank body sealing cover structure, including a tank body, a cover ring and a sealing cover, the mouth of the tank body is sealed and connected with a cover ring, and the cover ring is provided with a conical depression that is recessed into the inner cavity of the tank, The center of the bottom of the conical depression is provided with an opening, and the opening is sealed and connected with a sealing cover film, and the sealing cover is arranged on the upper port of the depression of the cover ring. After the film, the sealing behind it mainly depends on the sealing connection between the sealing cover and the upper port of the recess to complete, and this sealing method is not conducive to the preservation of milk powder in the tank at first, and secondly, the milk powder is easily polluted.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a tank body sealing cover structure, including a tank body, a cover ring and a sealing cover, the mouth of the tank body is sealed with a cover ring, and the cover ring is provided with a The concave conical depression, the center of the bottom of the conical depression is provided with an opening, the opening is sealed and connected with a sealing cover film, the sealing cover is arranged on the upper port of the depression of the cover ring, the sealing cover and the sealing cover A second sealing cover is provided in the conical depression between the membranes, the radial edge of the second sealing cover is connected to the inner wall of the conical depression, and at least three groups of evenly distributed seals are arranged on the wall of the conical depression The inner convex buckle, the second sealing cover is fixed on the inner wall of the tapered recess on the lower side of the inner convex buckle through the inner convex buckle.

For an optimization of the utility model, an annular groove is provided at the upper end of the edge between the bottom of the conical recess and the opening, and the edge of the sealing cover film is embedded and connected in the annular groove through a sealing ring.

For an optimization of the present utility model, a pull ring is connected to the inner side of the sealing ring, a connection root is provided between the pull ring and the sealing ring, and a receiving connection is provided between the inner side of the ring groove and the edge of the opening. Root container.

For an optimization of the present utility model, the lower side of the edge of the second sealing cover is provided with a downwardly extending tapered lip, and the tapered lip is in sealing connection with the tapered recess on the lower side of the inner convex buckle.

For an optimization of the utility model, a handle is provided in the middle of the upper end of the second sealing cover.

For an optimization of the present utility model, a handle is provided on the edge side of the sealing cover film for easy opening of the sealing cover film.

Compared with the background technology, the utility model has the advantages of reasonable structure and convenient manufacture. The whole set of device adopts cylinder transmission, thereby preventing secondary pollution of the product; Cooling-storage after gluing, the overall performance is good, the action is fast, the control is easy, and the maintenance cost is low.
