[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1 , Figure 2 , Figure 3The image shows an embodiment of the tinplate vacuum can of this utility model. A tinplate vacuum can includes a tinplate box body 1, which is a box body with a box body opening 11 and a sealed storage cavity 12. A vacuum pumping device 2 is provided at the box body opening 11, which can make the storage cavity 12 a vacuum state. The vacuum device 2 is equipped with a lid 3, which can be closed and connected to the tin box body 1. The lid 3 has a through lid inlet 31 and a lid outlet 32. The lid inlet 31 is sealed to the tin box body 1. The vacuum device 2 includes a base 21 and a pressing body 22 that cooperates with the base 21. The pressing body 22 is equipped with a pressing cover 221. The pressing cover 221 has a circumferential locking part 2211 and an upwardly protruding pressing part 2222. The pressing part 2222 extends out of the lid outlet 32, and the locking part 2211 is locked in the lid outlet 32. The base 21 is fixed inside the lid 3. The pressing body 22 extends out of the lid outlet 32. It also includes a return spring 23 and a pressing body sealing ring 24 located between the base 21 and the pressing body 22. A first one-way valve 25 is installed on the pressing body 22, and a second one-way valve 26 is installed on the base 21. The first one-way valve 25 and the second one-way valve 26 are located in the same closed base cavity 27. The first one-way valve 25 can be opened to the outside space, and the second one-way valve 26 can be opened from the storage cavity 12 to the base cavity 27. A vent valve 28 is also provided on the base 21. The vent valve 28 has a vent valve inlet 281 that can communicate with the storage cavity 12, and a vent valve outlet 282 that can communicate with the outside space. The base 2 is fixedly connected to the box cover 3. A box body sealing ring 131 is provided between the upper edge 13 of the box body and the vacuum device 2 at the opening 11 of the box body. In this embodiment, to ensure airtightness, the tinplate box body 1 can be formed by stamping or double-stamping and flattening, such as the technical solution with patent number ZL201310736948.9. Alternatively, it can be a box body formed by connecting two pieces of tinplate with rolled edges, where injection sealing or interlayer sealing can be used, such as the technical solution with patent number 201220614500.0. Or, the inner surface of the box can be covered with a single piece of plastic mold, etc.Thus, in use, an item is placed in the storage cavity 12, and the vacuum device 2 and the lid 3 are fastened onto the tin box body 1. The storage cavity 12 of the box body 1 is now isolated from the outside world. When the pressing part 2222 is pressed by hand, the pressing cover 221 will cause the pressing body 22 to move downward. At this time, the first one-way valve 25 is opened and the second one-way valve 26 is closed. The gas in the base cavity 27 will enter the outside space through the first one-way valve 25 and the gap 33 between the pressing cover 221 and the lid 3. When the pressing part 2222 is released, the pressing body 22 will move upward under the action of the return spring 23. At this time, the first one-way valve 25 is closed and the second one-way valve 26 is opened, and the air in the storage cavity 12 will enter the base cavity 27. Repeating the above operation can create a relative vacuum in the storage cavity 12.

[0026] like Figure 4 The illustration shows a second embodiment of the tinplate vacuum can of this utility model. Unlike the first embodiment, in this second embodiment, an inner box body 1A is fixed inside the tinplate box body 1. This inner box body 1A is a plastic box body. The top of the tinplate box body 1 has a rolled edge 13. The outer wall of the inner box body 1A has an inner box upper surround 1A1 and an inner box body retainer 1A2. The rolled edge 13 is engaged between the inner box upper surround 1A1 and the inner box body retainer 1A2. A support base 1A3 extends from the outer bottom surface of the inner box body 1A. A support plate 14 is provided at the bottom of the tinplate box body 1. The support base 1A3 is disposed on the support plate 14. The support plate 14 has a groove 141, and part of the support base 1A3 is located within the groove 141. The bottom of the tin box body 1 is provided with a vertical plate 15, which is fixedly connected to the support plate 14 to support the support base 1A3. The vertical plate 15 is fixed together with the stamped flange of the tin box body 1. In this embodiment, a sealing cover plate 33 is provided inside the box cover 3. The sealing cover plate 33 has a cover plate through hole 331. An inner box body sealing ring 1A5 is provided on the top surface 1A4 of the inner box body 1A. The sealing cover plate 33 is located on the top surface 1A4 of the inner box body. The top end of the inner box body 1A extends outward to have an inner box body opening extension 1A6. The inner box body opening extension 1A6 and the inner box body enclosure 1A1 form a clamping opening 1A7. A box cover retainer 34 is provided on the inner wall of the box cover 3. The inner box cover retainer 34 can be provided in the clamping opening 1A7. Compared to Embodiment 1, Embodiment 2 features an inner box body 1A, which allows for a higher vacuum level within the storage cavity. The support base further stabilizes the inner box body, preventing relative movement or wobbling. The tinplate box body 1 and the plastic inner box body 1A are combined to form a single unit, making the vacuum container resistant to impacts, providing excellent sealing, and ensuring long-term use, thus meeting consumer needs.

[0027] like Figure 5 , Figure 6The image shows a third embodiment of the tinplate vacuum can of this utility model. Based on, but differing from, embodiment three features a tinplate lid 3A covering the outer lid 3. This tinplate lid 3A has a rolled edge 3A1 at the bottom end, and a tinplate body retainer 16 is provided on the tinplate body 1. The tinplate lid 3A can be snapped onto the tinplate body 1 to cover the lid 3. Thus, the tinplate lid 3A effectively protects the lid 3.
