Gasket body, detachable sealing cover and container

Abstract

A gasket body, a detachable sealing cover and a container, include a body, a sealing element and a magnet. The body includes a main plane and a peripheral wall located on the periphery of the main plane. The sealing element is connected to the periphery of the peripheral wall. The main plane is provided with a mounting blind hole, which has an opening facing inward. The magnet is mounted into the mounting blind hole from the opening. The main plane is provided with through holes. Due to its magnetism, the magnet located inside the mounting blind hole can facilitate the connection or removal of the sealing cover, the sealing element on the periphery can improve sealing ability, and when the sealing cover is closed, part of the air in the container can be discharged from the through holes and sealing element, forming a stronger negative pressure and enhancing sealing ability.

DETAILED DESCRIPTION

Embodiment of Gasket Body

(7) As shown in FIG. 1 to FIG. 3, the gasket body 2 comprises a body 21, a sealing element 22 and a magnet 23, the body 21 comprises a main plane 214 and a peripheral wall 215 located on the periphery of the main plane 214, a locking flange 216 is circumferentially arranged on the radial outer wall of the peripheral wall 215, the sealing element 22 is connected on the periphery of the peripheral wall 215, the main plane 214 is provided with a mounting blind hole 213 at the center of the main plane 214, the mounting blind hole 213 has an opening facing inward to the lid 11, the part of the main plane 214 located at the mounting blind hole 213 protrudes outward, the protrusion 212 protrudes outward away from the lid 11, the magnet 23 is mounted into the mounting blind hole 213 from the opening, the main plane 214 is provided with a plurality of through holes 211 on the radial periphery of the mounting blind hole 213, and the plurality of through holes 211 are in different sizes and shapes and can be combined into various patterns or shapes. Although the body is round and the sealing element is annular in the embodiment, the body can be in other polygons, too, e.g., triangle, square or star, and the sealing element surrounds the outer edge of the body. In this way, the present invention can be implemented, too.

(8) The sealing element 22 is circumferentially provided with a locking slot 221. When the sealing element 22 is connected to the body 21, the locking slot 221 is sleeved outside the locking flange 216. Specifically, the body 21 can be made of hard plastics, such as PP, PE, PC, ABS and other regular plastics, while the sealing element 22 can be made of soft plastics, such as TPE, TPU, TPR and other materials, and there are various production methods. For example, the sealing element 22 and the body 21 are injection-molded, respectively and then are assembled. A better production method is to form the sealing element 22 and the body 21 through secondary injection molding, i.e., to produce the body by the method of injection molding at first, and then conduct injection molding again around the body to form an integrated component including the sealing element combined with the body. This production method avoids the use of adhesives and other non-environment-friendly materials. As the sealing element and the body are both plastic products and adopt an integrated design, they are more suitable for recovery.

(9) The sealing element 22 is circumferentially provided with a first sealing face 222 on the radial outer side of the locking flange 216, the first sealing face 222 is adjacent to the base 111 of the lid 11, and the connecting face 231 of the magnet 23 at the opening is on the same plane of the first sealing face 222. The sealing element is circumferentially provided with a second sealing face 223 on the radial outer side of the locking flange 216. Compared with the first sealing face 222, the second sealing face 223 is farther from the base 111 of the lid 11, i.e., the second sealing face 223 is located outside the first sealing face 222, the radial length of the first sealing face 222 is greater than that of the second sealing face 223, the first sealing face 222 and the second sealing face 223 extend radially, respectively, and a sealing slot is formed between the first sealing face 222 and the second sealing face 223.

(10) A separate gasket body is unable to provide a complete sealing function, but as there are through holes on the gasket body, and the gasket body matched with a container in an appropriate size can serve as a cover partially covering the container, a container filled with dry fragrant flower for example. As another use, as the gasket body has a magnet, it can be attached to a metal plate as an ornament, for example, a refrigerator magnet for fixing notes on a refrigerator.

Embodiment of Detachable Sealing Cover

(11) The sealing cover 1 comprises a lid 11 and the gasket body 2 in the foregoing embodiment. The lid 11 is made of a metallic material that can be magnetically attracted. The lid 11 comprises a base 111 and a side wall 112 located on the periphery of the base 111, the axial thickness of the lid 11 is greater than the axial thickness of the sealing element 22, the gasket body 2 is arranged inside the lid 11, the magnet 23 is magnetically connected to the base 111, the first sealing face 222 is adjacent to the base 111, the outer edge of the sealing element 22, i.e., the outer edge of the first sealing face 222, is adjacent to the side wall 112, and the second sealing face 223 is separated from the side wall 112.

Embodiment of Container

(12) The container comprises a container body and the detachable sealing cover 1 in the foregoing embodiment. The container body is provided with a ring wall at the opening. When the sealing cover 1 is connected to the container body, the outer wall of the ring wall is fit inside the side wall 112 and located within the sealing slot, the axial end face of the ring wall is in interference fit with the first sealing face 222, and the inner wall of the ring wall is in interference fit with the second sealing face 223. When the sealing cover 1 is closed, part of the air in the container can be ejected out of the body from the through holes 211 and the outer edge of the first sealing face 222 of the sealing element 22, forming a stronger negative pressure and enhancing sealing ability. Further, at least one notch is arranged on the second sealing face 223. When the sealing element 22 is close to the ring wall at the opening, the second sealing face 223 can be more easily deformed to extend into the inner wall. Likewise, when the sealing cover is moved away from the container body, as the second sealing face 223 is more easily deformed than the first sealing face 222 does, a relatively smaller friction force is generated with the opening ring wall, thereby making it easier to pull out the sealing cover.

(13) It can be seen that the magnet located inside the mounting blind hole can facilitate the connection or removal of the sealing cover by means of the magnetism of the magnet, the sealing element on the periphery can improve sealing ability, and when the sealing cover is closed, part of the air in the container can be ejected from the through holes and sealing element, forming a stronger negative pressure and enhancing sealing ability. Further, the gasket body can be separated from the sealing cover, so it facilitates the recovery of the sealing cover and can also be used as a refrigerator magnet. Still further, the sealing cover may also be provided with vents, the gasket body is detachably connected to the sealing cover by means of magnetism and can be used on a container for aromatherapy or filled with balm.
