Description

Sealing cover for extendable applications

This creation refers to a closure for a malleable application of an open container, and more particularly to an integrally formed cover construction that can be applied to open containers of different sizes to achieve a sealing effect.

A sealing structure for use on an open container, conventionally, has a sealing structure of "covering the opening of the open container with a plastic film and then binding the wire or bundle of bundles to the outside of the opening"; however, the structure has a time of implementation Longer and less airtight problems, especially for applications that require fast reopening.

The sealing structure currently used on the open container is mainly a sealed structure in which a plurality of components are combined and used for a single-sized open container, such as the "sealing cap structure" of the Republic of China Patent Publication No. M427360 (Application No. 100220272) The patent case and the "sealing cover" invention patent case of the Republic of China Patent Publication No. I316499 (application number: 096122399). Such a sealed structure has many components and can only be used in a single size container.

The seal structure can be applied to open containers of different sizes, and there is a new patent case of "fresh cover structure" of the Republic of China Patent Publication No. M407028 (application number: 099220846), and the Republic of China patent notice M386868 (application number: 099206295) The new patent case for the "cover structure for containers" and the new patent case for "sealing cover structure improvement" of the Republic of China Patent Publication No. M353176 (application number: 097219449). The cover body in the three cases is closely combined with the container opening to achieve an airtight effect, and is composed of a plurality of components. The disadvantage is that it cannot be used on containers that are not flat.

The main object of the present work is to provide a sealing cover that can be used on open containers of different sizes, and to overcome the problem that a sealing structure generally applicable to open containers of different sizes cannot be used on open containers with uneven openings.

In order to solve the above problems, the seal cover of the presently extensible application is a rubber cover integrally formed of elastic rubber or semi-soft plastic, characterized in that the cover body comprises: a film portion which is a cover body a bundle of loops surrounding the outer edge of the film portion and having a thickness greater than the thickness of the film portion. By this design, the film portion can be stretched to cover the opening of the container of different sizes after being stretched, and the bundle ring portion can be tightly bundled to the outer wall of the opening of the container opening. After the cover body is stretched and covered on the opening of the open container, the sealing effect is isolated from the external environment.

In addition, the seal cover of the presently extendable application, in addition to the fact that the collar portion can be in close contact with the open outer wall of the container to provide a sealing function, the film portion can also be in close contact with the opening of the container to provide a second resealing function. At the same time, it can solve the problem that the sealing structure which can be generally applied to the open containers of different sizes cannot be used on the open container which is not flat.

[Fig. 3] is a cross-sectional view showing the sealing cap of the present invention applied to an open container.

As shown in Fig. 1, a perspective view of a possible embodiment of a seal cover 1 is disclosed for the present invention. As shown in the figure, the seal cover 1 of the ductile application comprises a film portion 11 and a bundle of ring portions 12. The sealing cover 1 is a rubber cover integrally formed of elastic or weather resistant rubber or semi-soft plastic. The film portion 11 of the sealing cover 1 is a stretchable dome-shaped film formed on the outer side of the edge of the film portion 11. An annular collar portion 12 that surrounds the thin film portion 11. The film portion 11 may be a flat surface and a cover film of other shapes; and the tow ring portion 12 is composed of at least one bundle ring, and the thickness of the collar portion 12 is larger than the thickness of the film portion 11.

The following is an application assembly method of the present invention: first, the inner side of the collar portion 12 is fastened to one end of the open outer wall 22 of the open container 2; then, the collar portion 12 is stretched so that the collar portion 12 surrounds the open container 2 Opening the outer wall 22; finally, the collar portion 12 is adjusted downward until the film portion 11 tightly covers the open periphery 21 of the open container 2, and all assembly is completed.

According to the above, the seal cover of the presently extensible application, in addition to the fact that the collar portion thereof can be in close contact with the open outer wall of the container to provide a sealing function, the film portion thereof can also be in close contact with the opening of the container to provide the second weight. The sealing effect can solve the problem that the sealing structure generally applicable to open containers of different sizes cannot be used on containers with uneven openings. It is true that the design of a good product is undoubted. It is hoped that the patent application will be filed in accordance with the law and the patent will be granted as soon as possible.
