Abstract

The utility model discloses a sealing cover capable of being buckled easily, which comprises a cover body. An inner sealing ring matched with the inside diameter of a metal ring cover on a tank body, and an outer sealing ring matched with the outer diameter of the tank opening of the tank body are arranged inside the cover body; an inner bulge is formed on the mouth rim of the outer sealing ring, and the inner bulge is matched with a groove on the tank body. The sealing cover capable of being buckled easily ensures that the overall production material cost of a packaging tank is reduced by 10 percent about, and the cover body is convenient to clean. Particularly, the inner sealing and the outer sealing are adopted on the same cover body, thereby meeting the sealing requirements and ensuring that the cover body can be opened conveniently, and any other tools are not required during the opening process of the cover body.

Description

Easily-buckled seal cover

Technical field

The utility model relates to a kind of cover that is used for pressed powder packing jar, particularly a kind of easily-buckled seal cover.

Background technology

As shown in Figure 1, existing pressed powder packing jar, after using, unlatching still can keep the leak free purpose in order to reach, often adopt the wire loop lid 2 consistent with tank body 1 material is set in the tank body 1, have 3 sealings of aluminium film at wire loop lid 2, on wire loop lid 2, establish metal inner cap 4 again, and then establish enclosing cover 5 on the jar mouth outside metal inner cap 4.This packing jar and cover have continued and have used decades, particularly use in a large number in commodity packagings such as milk powder, malt extract, cocoa power, and never change.In use, people can find, the unlatching of metal inner cap 4 extremely bothers, and often all will prize just and can open with instrument, and it almost is impossible empty-handedly wanting opening metal inner cap 4, with after rethink and also need will cover tight metal inner cap 4 time cost must strength, and between metal inner cap 4 and the wire loop lid 2 owing to be cooperation between metal and the metal, tolerance clearance is excessive, is difficult for sealing, cooperate too closely, open just more difficult.So it is very inconvenient that the cover of this structure uses, and the setting of metal inner cap 4, also wastes metallic material, the whole cost of packing jar also is difficult to descend.

Summary of the invention

The purpose of this utility model is to provide a kind of packing jar that can be held open after the use still conveniently to seal for the deficiency that solves above-mentioned technology, can make things convenient for repeated open to get thing again, and can save metallic material, reduce the easily-buckled seal cover of packing jar whole cost.

In order to achieve the above object, the easily-buckled seal cover that the utility model is designed comprises lid, is provided with inner seal ring that cooperates with wire loop lid internal diameter on the tank body and the outer seal ring that cooperates with tank body jar mouth external diameter in lid; In order to guarantee the leak tightness between lid and the tank body, the lid that has inner seal ring and outer seal ring is a soft materials, can be plastics especially.In order to obtain the fastness that covers of better leak tightness and lid, be provided with convex at the Kou Yanchu of outer seal ring, convex cooperates with groove on the tank body.In order to improve the leak tightness between inner seal ring and the wire loop lid, between the internal diameter contact surface of inner seal ring and wire loop lid, be provided with groove and the arcwall face that is interlocked.Can be that groove is located on the inner seal ring, arcwall face be located on the internal diameter contact surface of wire loop lid; Also can be that arcwall face is located on the inner seal ring, groove be located on the internal diameter contact surface of wire loop lid, and both have identical effect.

The resulting a kind of easily-buckled seal cover of the utility model owing to do not need to be provided with inner cap, make the integral production material cost of packing jar can descend about 10%, and lid also is convenient to clean again.Particularly on same lid by the sealing of inside and outside twice, both guaranteed the leak free needs, opening cover easily again need be by any instrument in the process of opening cover yet.

The specific embodiment

The utility model will be further described in conjunction with the accompanying drawings below by embodiment.

Embodiment 1:

As shown in Figure 2, the easily-buckled seal cover that present embodiment is described comprises lid 6, in lid 6, be provided with tank body 1 on wire loop cover inner seal ring 7 that 2 internal diameters cooperate and the outer seal ring 8 that cooperates with 1 jar of mouth external diameter of tank body; In order to guarantee the leak tightness between lid 6 and the tank body 1, the lid 6 that has inner seal ring 7 and outer seal ring 8 is soft materials, and present embodiment adopts plastic production.

Embodiment 2:

As shown in Figure 3, in order to obtain the fastness that covers of better leak tightness and lid 6, outer seal ring 8 mouthful be provided with convex 10 along 9 places, convex 10 cooperates with groove 11 on the tank body 1.

Embodiment 3:

As shown in Figure 4, in order to improve the leak tightness between inner seal ring 7 and the wire loop lid 2, between the internal diameter contact surface of inner seal ring 7 and wire loop lid 2, be provided with groove 12 and the arcwall face 13 that is interlocked.At this, can be that groove 12 is located on the inner seal ring 7, arcwall face 13 is located on the internal diameter contact surface of wire loop lid 2; Also can be that arcwall face 13 is located on the inner seal ring 7, groove 12 be located on the internal diameter contact surface of wire loop lid 2, and both have identical effect.
