[0032] Air gap D DETAILED DESCRIPTION

[0033] See also Figures 1 to 12 As shown, the present invention has a vacuum airtight can, comprising:

[0034] The container 1 has an open storage space 10 and a joint portion 11 on the top, and the storage space 10 is used for placing food.

[0035] The cover body 2 is tightly and slidably mounted on the joint portion 11 of the container 1. The cover body 2 has an air outlet groove 20, a control groove 21 and an air extraction groove 22. The air outlet groove 20 is located at the top of the cover body 2, and the air outlet groove 20 has an air outlet hole 200 and a first joint surface 201 extending outward from the air outlet hole 200. The air outlet hole 200 passes through the cover body 2 and is connected to the storage space 10 of the container 1. A stop ring 202 is protruded upward from the outer peripheral edge of the first joint surface 201. The control groove 21 is located at the side of the cover body 2, and the control groove 21 has a hole 210. The hole 210 passes through the cover body 2 and is connected to the storage space 10 of the container 1. The air extraction groove 22 is located at the top of the cover body 2 and is provided with an air extraction hole 220. The air extraction hole 220 passes through the cover body 2 and is connected to the storage space 10 of the container 1, and a concave rib 221 is protruded upward from the outer peripheral edge of the air extraction groove 22.

[0036] The elastic gas outlet member 3 is provided with a first connection portion 30 and a second joint surface 31 extending outward from the first connection portion 30. The surface of the first connection portion 30 has adjacent concave and convex annular ribs 300 and a hook rib 301 at the end. The second joint surface 31 of the first connection portion 30 is arranged corresponding to the first joint surface 201 of the gas outlet groove 20, and a convex attachment portion 310 is arranged around the second joint surface 31 adjacent to the first connection portion 30. When the elastic gas outlet member 3 is arranged in the gas outlet groove 20, it can be stably placed in the gas outlet groove 20 due to the limitation of the stop ring 202 of the gas outlet groove 20, and when the first connection portion 30 of the elastic gas outlet member 3 is connected to the gas outlet hole 200 of the gas outlet groove 20, the attachment portion 310 of the second joint surface 31 will have a part of its area pressed tightly in the gas outlet hole 200, and the annular rib 300 and the hook rib 301 of the first connection portion 30 make the elastic gas outlet member 3 more closely attached to the gas outlet groove 20.

[0037] The control assembly 4 comprises a control member 40 , a clamping member 41 and an elastic member 42 . The control member 40 is integrally formed with a shaft 400 , and a surface of the shaft 400 comprises a receiving portion 401 and a hole 402 . The receiving portion 401 receives the clamping member 41 .

[0038] The tightening member 41 penetrates the hole 210 of the control groove 21 from the inner side of the cover body 2. When the shaft portion 400 of the control member 40 penetrates the elastic member 42 and enters the control groove 21 from the outer side of the cover body 2, the tightening member 41 is tightened in the hole 210 of the control groove 21 to close the hole 210. At this time, the hole 210 of the control groove 21 cannot communicate with the storage space 10 of the container 1, so that the storage space 10 of the container 1 is sealed and moisture-proof. In this embodiment, the elastic member 42 is a telescopic spring.

[0039] The air extraction assembly 5 comprises an air extraction member 50, an elastic positioning ring 51, an elastic leak-stopping member 52 and a fixing member 53. The air extraction member 50 is provided with a pressing part 500, a side wall of the pressing part 500 is provided with an annular groove 501, a top is provided with a pull block 502, and a bottom is provided with an air flow groove 503, a stop block 504 is provided with a protrusion on the air flow groove 503, and a plurality of notches 505 are provided at the outer end edge of the pressing part 500, and each notch 505 is connected with the annular groove 501. The elastic positioning ring 51 is slidably provided in the annular groove 501 of the pressing part 500, and when the air extraction member 50 is not pulled upward, the elastic positioning ring 51 is closely attached to each notch 505 of the pressing part 500.

[0040] The elastic leak-proof member 52 is provided with a second connection portion 520 at a position corresponding to the air extraction hole 220 of the air extraction groove 22, and the elastic leak-proof member 52 is connected to the air extraction hole 220 of the air extraction groove 22 via the second connection portion 520. The fixing member 53 is hollow and is provided with a convex rib 530 corresponding to the concave rib 221 of the air extraction groove 22, and the surface of the fixing member 53 has a plurality of indication characters 531. In this embodiment, each indication character 531 can be a date representation, so as to provide the user with the date when the food in the storage space 10 of the container 1 is stored.

[0041] When the vacuum member 50 is arranged in the vacuum groove 22 of the cover body 2, the abutment block 504 of the pressing portion 500 of the vacuum member 50 is abutted against the elastic leak-stopping member 52, and the convex rib 530 of the fixing member 53 and the concave rib 221 of the vacuum groove 22 are mutually engaged to prevent the vacuum member 50 from accidentally detaching from the vacuum groove 22 during the up and down movement.

[0042] Further, the use of the airtight can with vacuum of the present invention is described. Figure 7 and Figure 8 As shown, when the cover 2 is to be removed, the control member 40 of the control assembly 4 is only required to be pressed, so that the control member 40 pushes the elastic member 42 and the elastic member 42 is compressed, and the shaft portion 400 of the control member 40 protrudes from the hole 210 of the control groove 21 to the inside of the cover 2, so that the pressing member 41 of the shaft portion 400 of the control member 40 is separated from the hole 210 of the control groove 21, so that the hole 210 is opened and communicated with the storage space 10 of the container 1. At this time, the external air passes through the notch 402 of the shaft portion 400 of the control member 40 and passes through the hole 210 of the control groove 21 to enter the storage space 10 of the container 1, and then the cover 2 is removed.

[0043] On the contrary, when the cover 2 is to be placed on the container 1, the control member 40 of the control assembly 4 is also pressed. Similarly, because the external air can pass through the notch 402 of the shaft 400 of the control member 40 and pass through the hole 210 of the control groove 21, and form a communication relationship with the storage space 10 of the container 1, the cover 2 can be easily placed on the joint 11 of the container 1. When the control member 40 is released, the control member 40 forms a rebound action due to the elastic recovery of the elastic member 42, so that the tightening member 41 of the shaft 400 of the control member 40 is pressed against the hole 21 of the control groove 21, and the external air cannot communicate with the storage space 10 of the container 1. Under the principle of atmospheric pressure, the cover 2 is tightly placed on the container 1 and cannot be removed, so that the storage space 10 of the container 1 is sealed and moisture-proof.

[0044] Furthermore, when the food fermentation gas pressure in the storage space 10 of the container 1 increases, the gas in the storage space 10 of the container 1 will be discharged outwardly through the air gap D between the elastic gas outlet member 3 and the gas outlet groove 20 (such as Figure 5 As shown), the food will not be deteriorated due to excessive air pressure in the storage space 10 of the container 1.

[0045] In addition, when the storage space 10 of the container 1 is to be in a nearly vacuum state, the vacuum member 50 of the vacuum assembly 5 is pulled upward to separate the abutment block 504 of the pressing portion 500 from the abutment relationship with the elastic leak-stopping member 52 (such as Fig.10 As shown in FIG. 2 , the gas in the storage space 10 of the container 1 flows upward due to the upward pulling action of the air extraction member 50 and pushes the elastic leak-stopping member 52, so that a first channel 54 is formed between the elastic leak-stopping member 52 and the bottom of the air extraction groove 22 (as shown in FIG. 2 ). Fig.10 As shown in FIG. 1 , and in the process of pulling the air extraction member 50 upward, the elastic positioning ring 51 located in the annular groove 501 of the pressing part 500 moves downward under the influence of atmospheric pressure (as shown in FIG. 1 ). Fig.10 As shown), the ring body of the elastic positioning ring 51 will be slightly deformed, so that a plurality of second channels 55 (as shown) are formed between each notch 505 of the pressing part 500 and the elastic positioning ring 51. Fig.12 As shown). Therefore, the gas in the storage space 10 of the container 1 can flow to the airflow groove portion 503 through the first channel 54, and then flow to each second channel 55 through the airflow groove portion 503 to be discharged outside the container 1. On the contrary, when the air extraction member 50 of the air extraction component 5 is pushed downward, similarly, the elastic positioning ring 51 moves upward under the influence of atmospheric pressure and is tightly attached to each notch 505 of the pressing portion 500, thereby preventing external gas from entering the storage space 10 of the container 1 due to the downward pushing action of the air extraction member 50. Accordingly, by repeatedly pulling, pushing and releasing the air extraction member 50 of the air extraction component 5 in the air extraction groove 22 of the cover body 2, the gas in the storage space 10 of the container 1 can be extracted outside the container 1, so that the storage space 10 of the container 1 forms a nearly vacuum state.

[0046] In summary, the airtight can of the present invention forms a vacuum state in the storage space 10 of the container 1 by means of the air extraction member 50 of the air extraction assembly 5. Also, by pressing or releasing the control member 40 of the control assembly 4, the lid 2 and the container 1 can be easily assembled or disassembled, and when the food fermentation gas pressure in the storage space 10 of the container 1 increases, it can be discharged outward through the air gap D between the elastic air outlet member 3 and the air outlet groove 20, thereby achieving the purpose of preserving the food.
