Description

Sealing cover adaptive to containers of various specifications

Technical Field

The utility model relates to a sealed technical field specifically is a sealed lid of multiple specification container of adaptation.

Background

The sealing cap is commonly used for sealing the mouth of the container for storage, and generally comprises an outer cap and an inner cap or a sealing ring arranged in the outer cap as a combination. However, the sizes of the containers in the existing market are different, and the types of the containers comprise glassware, ceramic bowls, stainless steel boxes and the like, except that the opening flatness of the containers cannot be well guaranteed, and the shapes of some openings are irregular, so that the matching of the containers and the covers cannot achieve the most proper sealing state easily, and the sealing covers with specific sizes can only be suitable for the containers with specific sizes and shapes, so that the sealing covers have uniqueness. In order to solve the defects, the sealing cover which is suitable for containers with various specifications and has strong sealing performance is continuously provided.

Disclosure of Invention

The utility model aims at overcoming the defects of the prior art and providing a sealing cover which is simple in structure, convenient to use and good in sealing performance and is suitable for containers with various specifications.

The utility model discloses the purpose is realized with following mode: the utility model provides a sealed lid of multiple specification container of adaptation, covers including the face, its characterized in that, face lid below covers and has sealed the pad, the face lid andor sealed outer along the perk of filling up, sealed pad meets with the outer edge of face lid, thereby makes sealed pad and face cover between form cavity and the space of deformability, set up first through-hole on the sealing pad, the face is covered and is set up the second through-hole, install the check valve in the second through-hole. The outer edge of the surface cover and/or the sealing gasket is tilted, namely the surface cover or the sealing gasket can be tilted at any outer edge or both outer edges; namely, the outer edge of the surface cover is tilted, and the sealing gasket is connected with the outer edge of the surface cover; or the outer edge of the sealing gasket is tilted, and the surface cover is connected with the outer edge of the sealing gasket; or the outer edges of the surface cover and the sealing gasket are tilted, and the surface cover is connected with the outer edge of the sealing gasket.

The sealing gasket is made of elastic sealing materials.

The utility model has the advantages that: 1. simple structure, the cost of manufacture is low, improves market competition. 2. The sealing operation is simple and convenient. 3. The width of the end face of the sealing gasket is much larger than that of the traditional sealing ring, so that the sealing gasket can adapt to containers with various specifications. 4. Because the sealing gasket is made of elastic sealing materials and is molded, and the structure adopts the characteristic of forming a deformation space, the sealing gasket can be sealed with the container under the action of self gravity or other downward applied forces, and the sealing effect is good. The structure of soft material and deformable space can adapt to the container of multiple material, requires greatly reduced to container port plane degree or shape. 5. The one-way valve is arranged in the through hole of the face cover, so that air in the container can be effectively discharged outwards, and external air cannot enter the container, so that the air density in the container is lower relative to the outside and even in a vacuum state, the container is further sealed, and the sealing effect is ensured.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, the sealing cover adapted to containers with various specifications comprises a surface cover (1), wherein a sealing gasket (2) covers the lower part of the surface cover (1), the outer edge of the surface cover (1) is tilted, and the sealing gasket (2) is seamlessly connected with the tilted outer edge of the surface cover (1), so that a hollow and deformable space (21) is formed between the sealing gasket (2) and the surface cover (1). The sealing gasket (2) is made of elastic sealing materials and formed, and a first through hole (23) is formed in the deformation space (21) of the sealing gasket (2) so that the deformation space (21) is communicated with the container space (22). The face cover (1) is provided with a second through hole (24) in the area of the deformation space (21), a one-way valve (3) is arranged in the second through hole (24), at the moment, when pressure is applied to the face cover (1) or the sealing gasket (2) is pressed downwards under the action of the gravity of the sealing cover, the sealing gasket (2) is pressed into the container (4), so that the air of the container (4) is squeezed, the sealing gasket (2) is contacted with the port of the container (4) and is blocked by the port wall of the container (4) to deform to form a recess (5), the recess (5) is coated with the port of the container (4), the sealing contact area between the sealing gasket (2) and the port of the container (4) is increased, the air in the container (4) is prevented from being discharged from the port of the sealing gasket (2) and the port of the container (4) after being squeezed, and then the squeezed air can only flow into the deformation space (21) through the first through hole (23), and further the air is discharged outwards through the one-way valve (3) of the second through hole (24), and the external air is restricted by the one-way valve (3) and cannot reversely enter the container (4), so that the air pressure of the container (4) is lower than the external air, and the sealing cover is firmly fastened on the container (4) under the action of atmospheric pressure difference, thereby realizing the relative isolation and sealing between the inside of the container (4) and the outside. The sealing operation is simple and convenient, and the sealing performance is better.

Furthermore, as shown in fig. 4, a vacuum generator (6) is disposed above the sealing cover, the air suction port of the vacuum generator (6) is connected to the one-way valve (3), and after the vacuum generator (6) is started to perform the vacuum pumping action, the air in the container space (22) is further pumped away, and finally, the sealing effect relative to the vacuum can be formed.

The width of the end face of the sealing gasket (2) is larger than that of the traditional sealing gasket, so that the sealing gasket can be suitable for containers with various specifications. Moreover, because the whole sealed pad (2) of filling up is by the shaping of the sealed material preparation of elasticity, the soft material makes sealed pad can adapt to the container (4) of multiple material, reduces the requirement to container (4) port plane degree.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
