Abstract

The utility model relates to a refreshing cover. The refreshing cover comprises a cover body and further comprises an elastic sealing ring, wherein the outer edge of the elastic sealing ring is fixedly connected with the outer edge of the cover body; the inner edge of the elastic sealing ring is a turnover part which can be turned outside and is used for sealing the outer wall of the peripheral edge of a container opening; the elastic sealing ring is made of silica gel or rubber; and the outer edge of the elastic sealing ring is fixedly connected with the outer edge of the cover body in a bonding manner. The refreshing cover has the beneficial effects that the outer edge of the elastic sealing ring is fixedly connected to the outer edge of the cover body, so that the elastic sealing ring only has a one-layer structure; compared with the existing refreshing cover with three layers of sealing rings, the product is lower in cost and easier in production; the elastic sealing ring and the cover body are fixedly connected, so that the possibility of the air leakage condition between the two layers of sealing rings for hooping the cover body in the existing refreshing cover product with the three layers of sealing rings can be avoided, the refreshing effect is good, and the economical and practical effects are achieved.

Description

Fresh-keeping cover

Technical field

The utility model relates to a kind of container cover, relates in particular to a kind of fresh-keeping cover.

Background technology

Container cover of the prior art basically all will be adaptive with vessel port the supporting use of container, yet, in the actual life; A lot of containers do not have the complete container lid, in the case, and in order to guarantee the fresh of food in the container; People can only utilize preservative film capping container usually, however poor, the cracky of preservative film fastness, and preservative film is a disposable product; The waste resource, so, the wider container cover product that has seal ring of a kind of Applicable scope has just appearred; Yet the seal ring that this series products adopted at present all is a three-decker, two-layerly connects lid in order to hoop, and one deck is sealed on the outer wall of vessel port periphery in order to turnover; The defective of the container cover of this three-layer sealed coil structures is, complex structure connects in order to hoop between the two-layer seal ring of lid and leaks gas, influences fresh-keeping effect easily; Simultaneously, three-layer sealed coil structures makes its cost too high, is unfavorable for production and selling.

The utility model content

In view of this, the utility model technical matters to be solved is: a kind of good airproof performance, simple in structure is provided, the fresh-keeping cover of low cost of manufacture.

In order to achieve the above object, the utility model adopts following technical scheme to realize:

A kind of fresh-keeping cover comprises lid, wherein, also comprises elastic seal ring, and the outer rim of said elastic seal ring is captiveed joint with the outer of said lid, and the inner edge of said elastic seal ring is for can turn up in order to be covered in the turnover portion on the vessel port peripheral outer wall.

As preferably, said elastic seal ring is silica gel or rubber material.

As preferably, said elastic seal ring outer rim is bonding with captiveing joint of said lid outer.

Can know that by technique scheme the beneficial effect of the utility model is:

Compare prior art; The utility model directly is fixed on the outer of lid through the outer rim with elastic seal ring, makes its elastic seal ring have only one deck structure, lower than the fresh-keeping cover product cost of existing three-layer sealed coil structures, produce easier; And elastic seal ring is captiveed joint with lid; Avoid just can existing in the fresh-keeping cover product of existing three-layer sealed coil structures in order to hoop connect the situation that leaks air between the two-layer seal ring of lid maybe, good refreshing effect, economical and practical.

Description of drawings

Fig. 1 is for having the structural representation of the fresh-keeping cover product of three-layer sealed coil structures in the prior art.

Fig. 2 is for having the running condition scheme drawing of the fresh-keeping cover product of three-layer sealed coil structures in the prior art.

Fig. 3 is the structural representation one of the utility model, its signal be that turnover portion is in the state structure in following time of not turning up.

Fig. 4 is the structural representation two of the utility model, its signal be that turnover portion is in the state structure in following time of turning up.

The specific embodiment

In order to make those skilled in the art can further understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing about the utility model.

See also Fig. 1 to shown in Figure 4, the utility model provides a kind of fresh-keeping cover, comprises lid 1; Wherein, Also comprise elastic seal ring, the outer rim 2 of said elastic seal ring is captiveed joint with the outer of said lid, and the inner edge of said elastic seal ring is for can turn up in order to be covered in the turnover portion 3 on the vessel port peripheral outer wall; Said elastic seal ring is silica gel or rubber material, and said elastic seal ring outer rim is bonding with captiveing joint of said lid outer.

But the preferable possible embodiments that the above is merely the utility model is not the claim in order to limitation the utility model, so the equivalent structure that all utilization the utility model specification sheetss and accompanying drawing content are done changes, all in like manner is included in the scope of the utility model.

Claims

1. a fresh-keeping cover comprises lid, it is characterized in that, also comprises elastic seal ring, and the outer rim of said elastic seal ring is captiveed joint with the outer of said lid, and the inner edge of said elastic seal ring is for can turn up in order to be covered in the turnover portion on the vessel port peripheral outer wall.

2. fresh-keeping cover as claimed in claim 1 is characterized in that, said elastic seal ring is silica gel or rubber material.
