Description

Technical Field

[0001] The present invention relates to a sealed can, and more particularly to a push-type sealed can. Background Art

[0002] A sealed can is a can used to store food, isolating the food from contact with air and preventing the food from getting damp and moldy when placed in the air. Due to its light weight, portability and strong practicability, etc., it is widely used in daily production and life. However, most of the existing sealed cans have ordinary structures, with unsatisfactory sealing effects and relatively cumbersome operations. Summary of the Invention

[0003] In view of the above problems, the present invention aims to provide a push-type sealed can with novel structure, convenient operation and good sealing effect.

[0004] The technical solution of the present invention is a push-type sealed can, which includes a can body and a can lid. An installation plate is connected to the lower end of the can lid. A movable plate is arranged on the installation plate. The outer edge of the installation plate is embedded and covered with a sealing soft rubber. The outer diameter of the installation plate is smaller than the outer diameter of the movable plate, the outer diameter of the movable plate is smaller than the inner diameter of the can body, and the outer diameter of the sealing soft rubber is larger than the inner diameter of the can body. Guide columns longitudinally extend out from the front and rear sides of the movable plate.

Oblique long holes for sleeving the guide columns are arranged at the front and rear two end heads on the inner side of the push plate. The oblique long holes are inclined downward from the outside to the inside. A button is arranged in the middle on the outer side of the push plate. The button passes through the holes on the left and right sides of the can lid. Compression springs are arranged between the left and right push plates and the inner side walls of the push plate installation cavities. In the normal state, the compression springs push the push plates outwards, the movable plate presses the sealing soft rubber downwards to expand, and when the buttons on both sides are pressed inwards, the movable plate drives the guide columns to rise through the oblique long holes, thereby driving the movable plate to rise, so that the movable plate is separated from the sealing soft rubber to facilitate the free deformation of the sealing soft rubber.

[0005] Preferably, two rows of front and rear clamping plates are arranged on the bottom surface of the can lid. Clamping holes are arranged on the clamping plates. A plurality of clamping plates are correspondingly arranged on the upper surface of the installation plate. Clamping hooks are arranged at the tops of the clamping plates. The installation plate is snap-connected in the clamping holes on the clamping plates of the can lid through the clamping hooks.

[0019] As Figures 1 to 8 shown, the present invention relates to a press-type structure sealed can, including a can body 1 and a can lid 2. A mounting plate 3 is connected to the lower end of the can lid 2. A movable plate 4 is arranged on the mounting plate 3. The outer edge of the mounting plate 3 is embedded and coated with a sealing soft rubber 5. The outer diameter of the mounting plate 3 is smaller than the outer diameter of the movable plate 4, the outer diameter of the movable plate 4 is smaller than the inner diameter of the can body 1, and the outer diameter of the sealing soft rubber 5 is larger than the inner diameter of the can body 1. Guide posts 6 extend longitudinally from the front and rear sides of the movable plate 4. Push plate mounting cavities 7 are arranged at the positions on the left and right sides of the movable plate 4 on the bottom surface of the can lid 2. Push plates 8 are respectively installed in the left and right push plate mounting cavities 7. Oblique long holes 9 for sleeving the guide posts 6 are arranged at the front and rear ends of the inner side of the push plate 8. The oblique long holes 9 are inclined downward from the outside to the inside. A button 10 is arranged in the middle of the outer side of the push plate 8. The button 10 passes through the holes on the left and right side surfaces of the can lid 2. Compression springs 11 are arranged between the left and right push plates 8 and the inner side walls of the push plate mounting cavities 7; in the normal state, the compression springs 11 push the push plates 8 outwards, the movable plate 4 presses the sealing soft rubber 5 downwards to expand, and when the buttons 10 are pressed inwards on both sides, the movable plate 4 drives the guide posts 6 to rise through the oblique long holes 9, thereby driving the movable plate 4 to rise, so that the movable plate 4 is separated from the sealing soft rubber 5 to facilitate the free deformation of the sealing soft rubber 5.

[0020] On the basis of the above solution, two rows of clamping plates 12 are arranged on the bottom surface of the can lid 2. Clamping holes 13 are arranged on the clamping plates 12. A plurality of clamping plates 14 are correspondingly arranged on the upper surface of the mounting plate 3. Hooks 15 are arranged at the tops of the clamping plates 14. The mounting plate 3 is snap-connected into the clamping holes 13 on the clamping plates 12 of the can lid 2 through the hooks 15.

[0021] In addition, the push plate 8 includes a longitudinal plate 81 on the outer side. Two parallel transverse plates 82 extend inwards from the front and rear ends of the longitudinal plate 81. The oblique long holes 9 are located at the front ends of the transverse plates 82. A plurality of guide plates 16 for guiding the left and right lateral sliding of the push plate 8 are arranged on the push plate mounting cavity 7. A spring mounting seat 83 extends inwards from the inner side of the longitudinal plate 81. The compression spring 11 is arranged at the spring mounting seat 83. An extension section extends outwards from the middle of the outer side of the longitudinal plate 81.

[0022] In addition, a sleeve 31 extends upward from the middle of the mounting plate 3. A sleeve mounting cavity 41 for the sleeve 31 to pass through is provided in the middle of the movable plate 4. A sealing plug 32 is provided at the bottom of the inner hole of the sleeve 31. A ventilation hole 33 is provided at the center of the sealing plug 32. A push-button spring lock 34 and a sealing gasket 35 are provided above the sealing plug 32 inside the sleeve 31. The top of the push-button spring lock 34 is connected to a push-button cover 36. Pressing the push-button cover 36 downward causes the spring lock 34 to snap downward or spring upward to make the sealing gasket 35 in a sealed or open state.

[0023] During use, press the buttons 10 on both sides by hand. The push plate 8 moves inward, drives the guide post 6 to move upward through the front oblong hole 9, the movable plate 4 is lifted upward, and the movable plate 4 is separated from the sealing soft rubber 5. The can lid 2 is loaded into the can body 1. During the loading process, the sealing soft rubber 5 contacts the inner side wall of the can body 1 and then curls and deforms upward. When the loading is in place, release the button 10. Under the elastic force of the spring 11, the push plate 8 is pushed outward, and the movable plate 4 presses the sealing soft rubber 5 downward, so that the sealing soft rubber 5 closely adheres to the inner side wall of the can body 1, achieving a better sealing effect. In addition, for the exhaust structure in the middle of the can lid 2, the communication or closing between the internal ventilation hole 33 and the outside can be realized through the push-button spring lock 34 and the sealing gasket 35, which is convenient for storing some foods that need to exhaust, such as coffee beans, etc.
