Description

Improved sealing cover

Technical Field

The utility model relates to an improvement type sealed lid indicates especially the sealed lid of improvement type that can be applicable to the container of multiple different materials.

Background

As shown in fig. 7, in order to store or carry the beverage, a user may pour the beverage into a container 80, and a sealing cover is disposed at an opening 81 of the container 80, so as to seal the container 80 by the sealing cover, so that the beverage contained in the container 80 will not leak, wherein the container 80 has a screw-threaded section 82 at the opening 81, and the sealing cover includes a cover body 90 and an annular rubber gasket 91, an annular accommodating groove 92 and a screw-threaded section 93 are formed inside the cover body 90, the rubber gasket 91 is disposed in the accommodating groove 92 of the cover body 90, when the sealing cover is disposed at the opening 81 of the container 80, the screw-threaded section 93 of the sealing cover is screwed with the screw-threaded section 82 at the opening 81 of the container 80, so that the opening 81 of the container 80 can tightly abut against the rubber gasket 91 of the sealing cover, thereby achieving the sealing effect.

However, when the sealing cap is applied to containers 80 made of different materials, the sealing cap and the opening 81 are not screwed together because of the different material properties and hardness of each material, and the sealing effect and the screwing degree between the container 80 and the sealing cap are affected.

For example, when the sealing cap is disposed on the container 80 made of glass, the threaded segment 93 of the sealing cap is difficult to be completely screwed into the threaded segment 82 of the opening 81, so that the opening 81 of the container 80 is difficult to be completely pressed against the rubber pad 91 of the sealing cap, resulting in poor sealing effect between the container 80 and the sealing cap, and therefore, the rubber pad 91 with a thicker thickness is required to be selected to achieve complete sealing effect; however, when the sealing cover is installed on the container 80 made of plastic, if the rubber pad 91 with a relatively large thickness is used, the sealing cover is difficult to screw, so that the sealing cover of the prior art cannot be completely applied to the containers 80 made of various materials, and improvement is still needed.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The following description of the preferred embodiments of the present invention will be made in conjunction with the drawings and the accompanying drawings to further illustrate the technical means adopted to achieve the objects of the present invention.

Referring to fig. 1 to 4, a preferred embodiment of the improved sealing cover of the present invention includes a cover 10 and an annular gasket 20.

As shown in fig. 1 to 4, an annular stop wall 11 and an annular receiving groove 12 are formed on the inner top surface of the lid 10, a threaded section 13 is formed on the inner wall surface of the lid 10, and the receiving groove 12 is formed between the stop wall 11 and the inner wall surface of the lid 10, wherein at least one notch 14 is formed on the stop wall 11 of the lid 10, and the notch 14 extends upward from the bottom edge of the stop wall 11.

As shown in fig. 1 to 4, the annular gasket 20 is disposed in the receiving groove 12 of the cover 10, the annular gasket 20 includes an inner ring portion 21 and an extending portion 22, the inner ring portion 21 surrounds and is attached to the periphery of the stopper wall 11 of the cover 10, the extending portion 22 extends radially outward from the bottom end of the inner ring portion 21, and a deformation space 23 is formed between the extending portion 22 of the annular gasket 20 and the inner top surface of the cover 10.

As shown in fig. 5 and 6, the improved sealing cover of the present invention can be applied to

containers

30a and 30b made of different materials, and when the improved sealing cover is disposed on the

containers

30a and 30b, the improved sealing cover can be screwed on the screw segments 32 of the

containers

30a and 30b by the screw segments 13 of the cover 10, so that the

containers

30a and 30b can push against the annular gasket 20 to achieve the sealing effect.

And wherein, the utility model discloses the sealed lid of improvement type can make by means of the structural design of this annular gasket 20 when the sealed lid of improvement type sets up in the container 30a of different materials, the opening 31 of

container

30a, 30b can butt really the extension 22 of annular gasket 20, just the deformation space 23 between the extension 22 of annular gasket 20 and the interior top surface of this lid 10 can provide the extension 22 of annular gasket 20 has sufficient space to produce the deformation under pushing away of

container

30a, 30b, consequently, can effectively avoid the sealed lid of improvement type sets up when the container 30a of different materials, 30b, has the unable scheduling problem of screwing or becoming flexible, makes the sealed lid of improvement type can be applicable to the container 30a of multiple material, 30 b.

For example, as shown in fig. 5, when the improved sealing cap is disposed on a container 30a made of plastic material such as plastic, the thread portion of the improved sealing cap can be completely screwed into the threaded section 32 of the container 30a, so that the opening 31 of the container 30a can be tightly pressed against the extending portion 22 of the annular gasket 20, and the joint between the inner ring portion 21 and the extending portion 22 is squeezed between the container 30a and the stop wall 11 of the cap body 10, thereby achieving the sealing effect.

As shown in fig. 6, when the improved sealing cover is disposed on a container 30b made of a hard material such as glass, since the material of the container 30b is hard, the thread portion of the improved sealing cover cannot be completely screwed into the screwing section 32 of the container 30b, at this time, the opening 31 of the container 30b pushes against the extending portion 22 of the annular gasket 20 and deforms the extending portion 22 toward the deformation space 23, and the joint between the inner ring portion 21 and the extending portion 22 is squeezed between the container 30b and the stop wall 11 of the lid 10, so that the improved sealing cover still provides a good sealing effect when disposed on the container 30 b.

In addition, as shown in fig. 1 to 4, when the improved sealing cap is cleaned, a user can directly insert a finger into the notch 14 of the cap body 10 and press the top end of the inner ring portion 21 of the annular gasket 20, and at this time, the inner ring portion 21 moves toward the deformation space 23, so that a consumer can take out the annular gasket 20 in a hooking manner and clean the receiving groove 12 and the annular gasket 20 of the cap body 10, which can improve the cleaning convenience of the improved sealing cap and prevent the generation of germs therein.

To sum up, the improved sealing cover of the present invention mainly uses the extension portion 22 of the annular gasket 20 to match the deformation space 23 between the extension portion 22 of the annular gasket 20 and the inner top surface of the cover 10, so as to provide that the extension portion 22 of the annular gasket 20 has enough space to deform under the pushing of the

containers

30a and 30b, so that the improved sealing cover can be applied to the

containers

30a and 30b made of multiple materials, and in addition, when the extension portion 22 is pushed by the

containers

30a and 30b, the connection portion between the extension portion 22 and the inner ring portion 21 can be squeezed into the space between the stopping wall 11 of the

containers

30a and 30b and the cover 10, thereby further improving the sealing effect between the improved sealing cover and the

containers

30a and 30 b.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with the preferred embodiment, but not limited to the present invention, any skilled person in the art can make some modifications or equivalent changes to the technical content disclosed above without departing from the technical scope of the present invention, but all the technical matters of the present invention are within the scope of the technical solution of the present invention.
