Description

Technical Field

[0001] The invention relates to a sealed container, in particular to a vacuum sealed container with a lifting and sliding sealing top cover. Background Art

[0002] Sealed containers, such as sealed cans and fresh-keeping boxes, are used to store foods such as nuts, dried fruits, and biscuits to prevent them from getting damp. Existing sealed containers mostly include a container body and a lid, which are fixed to the container body by a snap fit or a buckle. Although such sealed containers can achieve a sealing effect, each time the lid is closed, a large amount of air remains in the container and cannot be discharged. Over time, the food will gradually get damp, thus affecting the taste. Therefore, people have invented a vacuum-evacuable sealed container, in which a vacuum valve is provided on the lid, and a vacuum pump is used to evacuate the valve. However, the lid of the sealed container with this structure is fixed, that is, when evacuating, the volume of the internal space remains unchanged, resulting in a poor vacuuming effect. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a vacuum-sealed container with a lifting and sliding sealing top cover, which reduces the internal space of the container body when vacuuming, has a good vacuuming effect, and improves the sealing performance.

[0004] The closure of the container is sealed with a sealing ring, and the closure is sealed with a sealing ring.

[0005] The present invention discloses a vacuum-sealed container with a lifting and sliding sealing top cover. When in use, the cover body is covered on the upper opening of the container body. At this time, the top cover in the cover body is in an ascending state. Then people use a vacuum pump (the specific structure of the vacuum pump is existing technology and can be directly purchased from the market) to vacuum the inlet and outlet air holes of the top cover. When the air inside the container body is gradually extracted, the top cover and the fixed ring are driven to move downward under the action of negative pressure, and the fixed ring drives one end of the sealing sleeve to move downward, thereby gradually reducing the space inside the container body until the outer retaining ring contacts the inner retaining ring of the mounting hole, and the top cover stops moving. When the vacuum is completed, the movable plug moves downward, and the sealing baffle of the movable plug is in sealing contact with the top cover, thereby preventing air from entering. This solution is a vacuum-sealed container with a lifting and sliding sealing top cover. A lifting and sliding top cover is provided on the cover body, and an elastic sealing sleeve is connected between the top cover and the cover body to prevent air from entering the container body through the gap between the top cover and the cover body. When vacuuming, negative pressure is used to drive the top cover, the fixing ring and the upper end of the sealing sleeve to move downward together to reduce the space inside the sealed container, thereby improving the vacuuming effect, improving the sealing performance of the container body, and preventing air leakage in the container body.

[0006] The present invention provides a vacuum-sealed container with a lifting and sliding sealing top cover. The upper end of the movable plug is provided with a pull block. When the lid is to be opened, the pull block is pulled upward by a finger to drive the movable plug upward, allowing air to enter the container body. The pull block makes pulling easy and convenient.

[0007] The movable stopper has a limit ring at its lower end, and a downward-pointing limit post is formed on the inner wall of the air inlet and outlet holes. The lower ends of the limit posts are evenly distributed with protrusions, and the lower ends of the protrusions cooperate with the limit ring, forming an air inlet and outlet channel between the protrusions. The limit ring prevents the movable stopper from falling out of the air inlet and outlet holes when pulled upward, thereby limiting the movable stopper. A downward-pointing limit post is formed on the inner wall of the air inlet and outlet holes, and the bottom of the limit post is formed with a protrusion and an air inlet and outlet channel. When the limit ring contacts the bottom of the limit post, air can enter the container body through the air inlet and outlet channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention relates to a vacuum sealed container with a lifting and sliding sealing top cover, such as Figure 1 — Figure 4As shown, it includes a container body 1, a cover body 2 is provided on the container body, a convex ring 3 is formed under the cover body 2, the outer wall of the convex ring is connected to the sealing sleeve 4, one end of the sealing sleeve is tightly sealed with the convex ring, and the outer wall of the sealing sleeve is formed with a protruding sealing ring 5, which is sealed with the inner wall of the container body 1, a mounting hole 6 is formed in the cover body 2, the inner wall of the mounting hole is formed with an inner retaining ring 7, a top cover 8 is provided in the mounting hole, the top cover and the mounting hole slide together up and down, an outer retaining ring 9 is formed around the top cover, the outer retaining ring cooperates with the inner retaining ring, a fixing ring 10 is provided on the inner wall of the top cover, the fixing ring is fixed to the inner wall of the top cover, a card groove 11 is formed on the fixing ring, a card hook 12 is formed at the other end of the sealing sleeve 4, the card hook is tightly sealed with the card groove, an air inlet and outlet hole 13 is opened in the top cover 8, a movable plug 14 is provided in the air inlet and outlet hole, a sealing baffle 15 is formed on the outer wall of the movable plug, and the sealing baffle and the top cover are located at the upper end of the air inlet and outlet hole 13 and are sealed and matched. During use, the cover body 2 is placed on the upper opening of the container body 1. At this time, the top cover 8 in the cover body is in an upward state. Then people use a vacuum pump (the specific structure of the vacuum pump is existing technology and can be purchased directly from the market) to evacuate the inlet and outlet holes 13 of the top cover 8. When the air inside the container body 1 is gradually extracted, the top cover 8 and the fixed ring 10 are driven downward by the action of negative pressure, and the fixed ring drives one end of the sealing sleeve 4 to move downward, thereby gradually reducing the space inside the container body until the outer retaining ring 9 contacts the inner retaining ring 7 of the mounting hole 6, and the top cover stops moving. When the vacuum is completed, the movable plug 14 moves downward, and the sealing baffle 15 of the movable plug is in sealing contact with the top cover, thereby preventing air from entering. This embodiment of a vacuum-tight container with a lifting and sliding sealing top cover comprises a lid body 2, a lifting and sliding top cover 8, and an elastic sealing sleeve 4 connected between the top cover and the lid body to prevent air from entering the container body 1 through the gap between the top cover and the lid body. During vacuuming, negative pressure is used to drive the top cover 8, the retaining ring 10, and the upper end of the sealing sleeve downward, thereby reducing the space inside the sealed container. This improves the vacuuming effect, enhances the sealing performance of the container body 1, and prevents air leakage. A pull block 16 is formed at the upper end of the movable plug 14. When the lid is to be opened, the pull block 16 can be pulled upward by a finger to move the movable plug 14 upward, allowing air to enter the container body 1. The pull block makes pulling easy and convenient. A limit ring 17 is formed at the lower end of the movable plug 14, and a downward-facing limit post 18 is formed on the inner wall of the air inlet and outlet 13. The lower ends of the limit posts are evenly distributed with protrusions 19, which cooperate with the limit ring 17 at the lower ends of the protrusions to form an air inlet and outlet channel 20. The limiting ring 17 prevents the movable plug 14 from falling out of the air inlet and outlet holes 13 when it is pulled upward, and plays a limiting role for the movable plug. A downward limiting column 18 is formed on the inner wall of the air inlet and outlet holes 13, and a protrusion 19 and an air inlet and outlet channel 20 are formed at the bottom of the limiting column. When the limiting ring is in limiting contact with the bottom of the limiting column 18, air can enter the interior of the container body 1 through the air inlet and outlet channel 20.
