[0002] Nowadays, a sealed can generally includes a container and a cover body with an airtight cover arranged at the opening of the container. The cover body is detachably covered on the container. In order to airtightly seal the opening of the container, an annular gasket is embedded at the bottom edge of the cover body, and the gasket is airtightly overlapped with the periphery of the opening of the container to achieve a sealing effect.

[0003] The existing sealing cover must be frequently disassembled and cleaned, so the industry has developed a sealing cover with a handle and an elastic element. This sealing cover is operated by pressing the handle, and the elastic force of the elastic element squeezes and deforms the gasket to achieve the sealing effect. However, during the assembly and disassembly process of this type of sealing cover, some require the removal of most components, and some only have a single-direction insertion port for assembly, which makes assembly and disassembly extremely inconvenient during disassembly and cleaning.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] See also Figure 1 and Figure 3 As shown, the present invention provides a sealing cover with a two-way locking mechanism. The sealing cover 1 mainly includes an upper cover component 10 , a lower cover component 20 , a locking member 30 , an elastic element 40 and a handle component 50 .

[0027] The upper cover member 10 of this embodiment is a quadrilateral, but is not limited to this shape. It can be made of plastic materials such as PP. This upper cover member 10 mainly includes a top plate 11 and an annular frame 12 extending downward from the top plate 11. A through hole 111 is provided at the center of the top plate 11, and a ring wall 112 extends downward from the periphery of the through hole 111; a stopper slope 121 is formed at the bottom edge of the annular frame 12. In addition, an upper ring 13 extends downward from the top plate 11 between the ring wall 112 and the annular frame 12. The upper ring 13 of this embodiment is a quadrilateral, and an elastic hook 131 is provided in the middle of each side of the upper ring 13.

[0028] The lower cover member 20 is disposed below the upper cover member 10, and its shape roughly corresponds to that of the upper cover member 10. The lower cover member 20 can be made of plastic materials such as ABS. The lower cover member 20 mainly includes a bottom plate 21 and a sealing ring 22 connected to the bottom plate 21, wherein the bottom plate 21 and the sealing ring 22 are made by injection molding. The manufacturing method can be to first make the bottom plate 21 in a mold, then place the bottom plate 21 in another mold, and then inject and solidify the liquid raw material into the sealing ring 2, wherein the bottom plate 21 and the sealing ring 22 are inseparable.

[0029] Furthermore, the sealing ring 22 of the present embodiment is made of silicone material, roughly in the shape of a quadrilateral ring, and mainly includes a connecting section 221 and an extrusion deformation section 222 extending from the connecting section 221. The connecting section 221 is fixed to the periphery of the bottom plate 21, and the extrusion deformation section 222 extends toward the upper cover component 10 and is formed on the outside of the aforementioned stop slope 121.

[0030] Furthermore, a lower ring 23 is extended from the position of the bottom plate 21 corresponding to the aforementioned upper ring 13, and a hook guide groove 231 is provided in the middle of each side of the lower ring 23. The lower ring 23 is mutually connected with the aforementioned upper ring 13, and each elastic hook 131 can move up and down in each hook guide groove 231.

[0031] Furthermore, a rectangular frame 24 extends upward from the middle of the bottom plate 21, and two corresponding buckle grooves 241 are formed on the side plates of the rectangular frame 24. A plurality of ribs 24 are formed between the outer periphery of the lower ring 23 and the bottom plate 21 to enhance the structural strength.

[0032] The buckle 30 has two corresponding buckle grooves 31 . Each buckle groove 31 includes a sliding channel 311 , a first inserting opening 312 and a second inserting opening 313 . The first inserting opening 312 and the second inserting opening 313 are respectively formed at two ends of the sliding channel 311 .

[0033] Furthermore, the sliding channel 311 is generally in an inverted V shape, with a buckle hole 314 provided at the tip, and a boss 315 formed directly below the buckle hole 314. The boss 315 of this embodiment is generally in a triangular shape. In addition, a climbing slope 316 is provided in the sliding channel 311 at the lower edge of the buckle hole 314. An insert block 32 is provided at the lower part of the fastening member 30, and two corresponding sides of the insert block 32 are respectively provided with a buckle hook 321.

[0034] The fastening member 30 is inserted into the rectangular frame 24 via the insert block 32 , and each snap hook 321 is snapped into the snap groove 241 and connected to the bottom plate 21 . The fastening member 30 penetrates the through hole 111 and is exposed outside the top plate 11 .

[0035] The elastic element 40 is a helical compression spring, which is sleeved around the outer periphery of the aforementioned rectangular frame 24 and the annular wall 112 , and is elastically clamped between the top plate 11 and the bottom plate 21 .

[0036] The handle member 50 can be made of plastic materials such as POM, and mainly includes a handle 51 and two arms 52 extending from the handle 51. Each arm 52 and the handle 51 are integrally formed by injection molding. A shaft rod 53 extends from each arm 52. Each shaft rod 53 can selectively enter from one of the first insertion openings 312 and the second insertion openings 313 and can move in each sliding channel 311. Each shaft rod 53 passes through each climbing slope 316 in sequence and then is locked and positioned in the fastening hole 314.

[0037] See also Figures 4 to 7 As shown, the sealing cover 1 of the present invention is used to be combined with a container 8. An opening 81 is formed above the container 8. The sealing cover 1 covers the position corresponding to the opening 81. When assembled, the fastening member 30 is inserted into the rectangular frame 24 through the insert block 32, and is fastened and connected with each snap hook 321 corresponding to each snap groove 241. The elastic element 40 is sleeved on the outer periphery of the rectangular frame 24 and the ring wall 112, and is elastically clamped between the inner surface of the top plate 11 and the bottom plate 21.

[0038] Next, the fastening member 30 is passed through the through hole 111, and the upper cover member 10 is pressed toward the lower cover member 20, so that a part of the fastening member 30 is exposed outside the top plate 11. At this time, each shaft rod 53 of the handle member 50 can be selectively inserted from one of the first insertion openings 312 and the second insertion openings 313, and each shaft rod 53 will reach the lower edge position of the climbing slope 316 through each sliding channel 311. After the handle member 50 is pulled upward, each support arm 52 and each shaft rod 53 will expand outward along the aforementioned climbing slopes 316. After each shaft rod 53 passes through the climbing slope 316, it is stuck in each fastening hole 314 by the restoring force of each support arm 52 itself, thereby forming a stable positioning effect (such as Figure 6 shown).

[0039] When the handle 51 is turned clockwise or counterclockwise during operation, each shaft 53 will pivot in the fastening hole 314, and the side surface of each support arm 52 will contact the outer surface of the top plate 11 (such as Figure 7 As shown in the figure, (i.e., the distance from the side of the support arm 52 to the shaft 53 is greater than the distance from the bottom of the support arm 52 to the shaft 53, or the aforementioned connection is called forming a height difference), at this time, the lower cover member 20 will move toward the upper cover member 10, and the annular wall 112 is sleeved around the outer periphery of the fastener 30, so that the lower cover member 20 can be stably guided to move, and the extruded deformation section 222 of the sealing ring 22 will be tightly sealed between the stop slope 12 and the inner wall of the container 8.

[0040] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
