Usually, adhesive tape is applied at the joint between the cardboard container and the cover, or sealing bags are wrapped around the inner and outer ends of the cardboard container. This is cumbersome and will incur additional expenses, increase production and use costs, and has certain limitations. Utility Model Content
[0004] The purpose of the utility model is to provide a cardboard container with good sealing effect to solve the problems raised in the above background technology.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a cardboard container with good sealing effect, including a container body, a group of fixing grooves are opened on the top of each of the four sides of the container body, a cover plate is connected to the top of the inner top of the container body, a group of handles are provided on the top of the cover plate, and a group of fixing blocks are provided at the positions of the outer ends corresponding to the fixing grooves, and the middle ends of the fixing blocks are connected to sealing mechanisms.
[0006] Preferably, the components of the sealing mechanism are all the same, and the sealing mechanism includes an expansion cavity, a connecting cloth, a slot and a connecting plate. A group of expansion cavities are provided at the positions of the four sides of the cover plate corresponding to the fixed blocks, a connecting cloth is provided on the inner side of the expansion cavity, and the middle end of the fixed block is provided with a slot that can be connected to the expansion cavity, a group of connecting plates are provided in the slot, and the inner end of the connecting plate is connected to the connecting cloth.
[0007] Preferably, the connecting cloth is elastic.
[0008] Preferably, a magnetic strip is provided on the outer side of the connecting plate, which can be adsorbed on the inner side of the slot.
[0009] Preferably, the handle is in an inverted "U" shape, with the left and right bottom ends extending and rising.
[0010] Preferably, the cover plate is made of hard material.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] A container body is provided, a group of fixing grooves are provided on the top of each of the four sides of the container body, and a cover plate is connected through the fixing grooves. A fixing block corresponding to the fixing groove is provided on the outside of the cover plate, and a sealing mechanism is provided on the inner end of the fixing block. The sealing mechanism includes components such as an expansion cavity, a connecting cloth, a slot and a connecting plate. The container body and the cover plate can be strengthened and connected with each other to make the two fit better and improve the connection sealing between the two. It is simple and convenient to use and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.
[0019] See also Figure 1-2 The utility model provides a cardboard container with good sealing effect, including a container body 1, a group of fixing grooves 2 are opened on the top of each of the four sides of the container body 1, a cover plate 3 is connected to the top of the container body 1, and a group of handles 4 are provided on the top of the cover plate 3. The handles 4 are in an inverted "U" shape, and the left and right bottom ends are extended and raised, which is conducive to the connection and fixation with the connecting cloth 62. A group of fixing blocks 5 are provided at the positions of the outer ends of the cover plate 3 corresponding to the fixing grooves 2. The fixing blocks 5 can be snapped into the fixing grooves 2 to achieve preliminary sealing between the container body 1 and the cover plate 3, and the middle ends of the fixing blocks 5 are connected to sealing mechanisms 6.
[0020] See also Figure 2-4The present invention provides a cardboard container with good sealing effect. The components of the sealing mechanism 6 are all the same. The sealing mechanism 6 includes an expansion cavity 61, a connecting cloth 62, a slot 63 and a connecting plate 64. A group of expansion cavities 61 are opened on the four sides of the cover plate 3 at the positions corresponding to the fixed block 5. The inner side of the expansion cavity 61 is connected to the connecting cloth 62. The connecting cloth 62 is elastic and easy to stretch. The middle end of the fixed block 5 is provided with a slot 63 that can be communicated with the expansion cavity 61. A group of connecting plates 64 are provided in the slot 63. The inner end of the connecting plate 64 is connected to the connecting cloth 62. By pulling out the connecting plate 64, the connecting cloth 62 is stretched and connected to the handle 4. Among them, the cover plate 3 is made of hard material, such as cardboard or corrugated cardboard. When the connecting cloth 62 is connected to the handle 4, it remains unchanged and has a good packaging sealing effect. Furthermore, a magnetic strip is provided on the outer side of the connecting plate 64, which can be adsorbed on the inner side of the slot 63 to prevent the connecting plate 64 from falling out of the slot 63.
[0021] Here's how it works:
[0022] During use, the cover plate 3 can be placed on the top of the container body 1 so that the fixing block 5 is stuck in the fixing groove 2 to achieve a preliminary seal between the container body 1 and the cover plate 3. Then, force can be applied to the connecting plate 64 in turn to pull it outward, and drive the connecting cloth 62 to stretch and wrap around the handle 4 to connect it, so that the top of the container body 1 is more closely attached to the outside of the cover plate 3, thereby improving the sealing effect.
[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
