Description

Technical Field

[0001] The utility model relates to the field of packaging cans, in particular to a packaging can that can be opened by rotation. Background Art

[0002] A packaging can refers to a packaging container with roughly the same cross-sectional shape at all locations on the can body, a short can neck, an inner diameter of the can neck that is slightly smaller than the inner neck of the can body, or no can neck.

[0003] The sealing cover on the existing packaging can is sealed by a threaded connection. Since a threaded groove is provided at the mouth of the packaging can and a threaded groove is also provided inside the sealing cover, the sealing cover needs to be placed on the mouth of the packaging can and then rotated along the threaded groove on the mouth of the packaging can to facilitate screwing it on the mouth of the packaging can to seal the mouth of the packaging can. However, when unscrewing the sealing cover, since the sealing cover is screwed tightly, a large force is required to unscrew it. In the process of unscrewing the sealing cover, the sealing cover needs to be rotated along the mouth of the packaging can for two or three turns before the sealing cover can be removed. The unscrewing process is relatively troublesome. If the user has less strength, it is not easy to unscrew the sealing cover, which is easy to affect the user's mood.

[0004] In view of the above problems, it is necessary to design a packaging can that can be opened by rotation. Utility Model Content

[0005] In order to overcome the disadvantage that the sealing cover needs to be rotated along the mouth of the packaging can for two or three circles before the sealing cover can be removed during the process of unscrewing the sealing cover, the utility model provides a packaging can that can be opened by rotation.

[0006] The technical scheme of the utility model is: a packaging can that is opened by rotation, comprising a packaging can, a sealing cover, a rotating block, a limiting disk, a fixed slide rail, an expansion block and a sealing ring, a sealing cover is placed on the packaging can, the sealing cover is rotatably connected with the rotating block, the lower part of the rotating block passes through the sealing cover and is connected with the limiting disk, the lower part of the rotating block is rotatably connected with the fixed slide rail, the expansion block is slidably connected in the fixed slide rail, the expansion block is slidably matched with the limiting disk, there are at least five expansion blocks, sealing rings are sleeved between the outer sides of all the expansion blocks, and also comprises a sliding frame, an elastic member and a wedge block, the sealing cover is connected with the sliding frame, the sliding frame is slidably connected with the wedge block, and an elastic member is connected between the wedge block and the inside of the sliding frame.

[0007] As a preferred technical solution of the utility model, it also includes a label frame, and the front side of the packaging can is connected with the label frame.

[0008] As a preferred technical solution of the utility model, a scale is also included, and the left side of the packaging can is connected with the scale.

[0009] As a preferred technical solution of the utility model, it also includes a prompt block, and the sealing cover is connected with the prompt block.

[0010] As a preferred technical solution of the utility model, a groove is provided on the rotating block.

[0011] As a preferred technical solution of the utility model, the contact surface between the expansion block and the sealing ring is semi-arc-shaped.

[0012] The beneficial effects of the utility model are as follows: the limiting plate is driven to rotate in the opposite direction by rotating the rotating block, and the limiting plate rotates in the opposite direction so that the expansion block moves along the slide groove thereon, and the expansion block moves along the fixed slide rail, and the expansion block drives the sealing ring to move, and after the sealing ring moves and fits the inner wall of the packaging can, it is convenient to seal the inside of the packaging can.

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0020] Embodiment: A packaging can that can be opened by rotation, such as Figure 1-Figure 5As shown, it includes a packaging can 1, a sealing cover 2, a rotating block 3, a limiting disk 4, a fixed slide rail 5, an expansion block 6, a sealing ring 7, a slide frame 8, an elastic member 9, a wedge block 10, a prompt block 11, a label frame 12 and a scale 13. A sealing cover 2 is placed on the packaging can 1, and a rotating block 3 is rotatably connected to the sealing cover 2. A groove is provided on the rotating block 3 to facilitate the user to rotate the rotating block 3. The lower part of the rotating block 3 passes through the sealing cover 2 and is connected to the limiting disk 4. The lower part of the rotating block 3 is rotatably connected to the fixed slide rail 5, and the expansion block 6 is slidably connected in the fixed slide rail 5. The expansion block 6 is slidably matched with the limiting disk 4. There are at least five expansion blocks 6, and all expansion blocks 6 are provided. A sealing ring 7 is sleeved between the outer sides of the expansion block 6 to seal the inside of the packaging can 1. The contact surface between the expansion block 6 and the sealing ring 7 is semi-arc-shaped. A sliding frame 8 is connected to the sealing cover 2. A wedge block 10 is slidably connected inside the sliding frame 8. An elastic member 9 is connected between the wedge block 10 and the inside of the sliding frame 8. The elastic member 9 is a compression spring. A prompt block 11 is connected to the sealing cover 2. The user can identify whether the sealing cover 2 is open or closed through the prompt on the prompt block 11. A label frame 12 is connected to the front side of the packaging can 1. The label strip can be placed in the label frame 12 to facilitate the user to identify the goods in the packaging can 1. A scale 13 is connected to the left side of the packaging can 1.

[0021] When the device needs to be used, since the initial state of the sealing cover 2 is the open state, the user removes the sealing cover 2 and then puts the goods into the packaging can 1. When a certain amount of goods are placed, the sealing cover 2 is put back on the packaging can 1, and then the rotating block 3 is rotated to drive the limiting plate 4 to rotate in the opposite direction. During the reverse rotation of the limiting plate 4, the expansion block 6 moves inward along the slide groove thereon, and the expansion block 6 moves outward along the fixed slide rail 5. The movement of the expansion block 6 drives the sealing ring 7 to move outward. During the movement of the sealing ring 7, the sealing ring 7 fits against the inner wall of the packaging can 1, which is convenient for sealing the inside of the packaging can 1. During the movement, the inclined surface on the rotating block 3 contacts and squeezes the inclined surface of the wedge block 10, so that the wedge block 10 moves inward along the sliding frame 8, and the elastic member 9 is compressed. When the rotating block 3 rotates counterclockwise to ninety degrees, the rotating block 3 is out of contact with the wedge block 10. Under the resetting action of the elastic member 9, the wedge block 10 moves outward along the sliding frame 8 to its original position, and the user releases the rotating block 3. At this time, the sealing cover 2 is tightened on the packaging can 1, and the written label strip is placed in the label frame 12, which is convenient for the user to identify the goods placed in the packaging can 1. If the sealing cover 2 needs to be removed, repeat the above reverse operation.

[0022] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
