Description
Technical Field
[0001] This utility model relates to the field of bottle caps, and more particularly to a bottle cap with a tear-off ring. Background Technology
[0002] Bottle caps are components used to close and seal the openings of containers. They are widely used in the food, beverage, pharmaceutical, and chemical industries. Containers commonly used in daily life are sealed with bottle caps to prevent dust and other debris from entering. Bottle caps can be divided into detachable and connectable types. Connectable bottle caps are widely used because they do not completely separate from the container after opening, providing better anti-loss performance.
[0003] Existing bottle caps typically have a sealing structure at the opening to prevent the product from being opened before sale and to further seal the bottle mouth and enhance the overall sealing ability of the device. However, to ensure the stability of the connection, the existing sealing structure has multiple sets of connecting feet. Although this can prevent the sealing structure from falling off, it makes it difficult for the operator to open the cap and makes it inconvenient to open the bottle cap. Therefore, a bottle cap with a tear-off ring is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a bottle cap with a tear-off ring, which aims to improve the problem in the prior art that "existing sealing structures are designed with multiple sets of connecting feet, which makes it difficult for operators to open the cap".
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bottle cap with a tear-off ring, comprising a connecting sleeve, a bottle cap fitted onto the upper surface of the connecting sleeve, a bottle body inserted into the lower surface of the connecting sleeve, a detachable closure buckle connected to the upper surface of the connecting sleeve, a slot provided on the rear surface of the closure buckle, a protruding plate provided on the front surface of the bottle cap, the protruding plate being inserted into the inner wall of the slot, a boss provided on the rear surface of the closure buckle, a connecting strip fixedly connected to the rear end of the boss, the rear end of the connecting strip being fixedly connected to the front surface of the connecting sleeve, a closure ring fitted onto the outer wall of the bottle body, the upper surface of the closure ring being detachably connected to the lower surface of the connecting sleeve, a limiting plate provided on the inner wall of the closure ring, a connecting strap fixedly connected to the right end of the connecting sleeve, and the other end of the connecting strap being fixedly connected to the right surface of the bottle cap.
[0006] As a further description of the above technical solution:
[0007] The outer wall of the bottle is provided with external threads, and the inner wall of the connecting sleeve is provided with internal threads, and the internal threads and external threads mesh with each other.
[0008] As a further description of the above technical solution:
[0009] The limiting plate is set in an inclined shape, one end of the limiting plate is fixedly connected to the inner wall of the closed ring, and the other end of the limiting plate is suspended in the air.
[0010] As a further description of the above technical solution:
[0011] The outer wall of the bottle is provided with a limiting block. The cross-section of the limiting block is triangular. One end of the limiting plate is suspended and corresponds to the parallel end face of the triangle of the limiting block. The inclined surface of the limiting block faces the direction of the external thread.
[0012] As a further description of the above technical solution:
[0013] The outer wall of the bottle is provided with a limit ring.
[0014] As a further description of the above technical solution:
[0015] Both ends of the connecting belt are connected to bent belts. The front end of the bent belt is fixedly connected to the rear surface of the connecting sleeve, and the rear end of the bent belt is fixedly connected to the rear surface of the connecting sleeve.
[0016] As a further description of the above technical solution:
[0017] The front surface of the connecting sleeve is provided with a snap groove.
[0018] As a further description of the above technical solution:
[0019] The closure buckle has bent edges at both ends.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, by reducing the number of connecting strips and setting connecting strips only in the lower half of the sealing buckle, the traditional connection method is changed. The bottle cap is locked by the cooperation of the slot and the convex plate, which ensures the sealing ability of the whole device. Firstly, the production difficulty of the whole device can be reduced due to the reduction of connection positions, and secondly, the difficulty of opening the whole device can be reduced. The whole device is more convenient in both production and use.
[0022] 2. In this utility model, by setting a limiting plate and a limiting block, when the operator attempts to rotate the connecting sleeve to separate it from the bottle body, the limiting plate will block the limiting block so that the closing ring cannot rotate with the bottle cap. The traditional structure can only force the connecting sleeve to separate from the closing ring by the upward pulling force of the connecting sleeve. However, with this structure, the connecting sleeve and the closing ring can be separated by the shear stress generated by the relative rotation of the connecting sleeve and the closing ring on the basis of the pulling force. The separation of the connecting ring of the whole device is more labor-saving. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a bottle cap with a tear-off ring, comprising a connecting sleeve 2, a bottle cap 3 for sealing the top opening of a bottle body 1 fitted onto the upper surface of the connecting sleeve 2, a bottle body 1 for storing liquid inserted into the lower surface of the connecting sleeve 2, a sealing buckle 4 for restricting the opening of the bottle cap 3 detachably connected to the upper surface of the connecting sleeve 2, a slot 41 for accommodating a protrusion 31 provided on the rear surface of the sealing buckle 4, and a protrusion 31 for restricting the rotation of the bottle cap 3 provided on the front surface of the bottle cap 3, the protrusion 31 being inserted into the inner wall of the slot 41. Because the protrusion 31 and the slot 41 are used for connection, no connecting structure is needed between the sealing buckle 4 and the bottle cap 3, making production more convenient and opening easier. A boss 44 for supporting a connecting strip 45 is provided on the rear surface of the sealing buckle 4, and a connecting sleeve is fixedly connected to the rear end of the boss 44. The connecting strip 45 of the 2 is fixedly connected to the front surface of the connecting sleeve 2. The connecting strip 45 and the connecting sleeve 2 are integrally formed. Since the connection area between the boss 44 and the closing buckle 4 is larger, the two are not easy to separate. Therefore, when the closing buckle 4 is removed, the connecting strip 45 and the boss 44 are not easy to remain on the outer wall of the connecting sleeve 2. The outer wall of the bottle body 1 is fitted with a closing ring 5 for connecting the bottle body 1 and the connecting sleeve 2. The upper surface of the closing ring 5 is detachably connected to the lower surface of the connecting sleeve 2. The inner wall of the closing ring 5 is provided with a limiting plate 51 for preventing the closing ring 5 from rotating. The right end of the connecting sleeve 2 is fixedly connected with a connecting strap 6 for connecting the connecting sleeve 2 and the bottle cap 3. The other end of the connecting strap 6 is fixedly connected to the right surface of the bottle cap 3. By setting the connecting strap 6, the bottle cap 3 can be prevented from separating from the connecting sleeve 2 at will, thus preventing the bottle cap 3 from being lost.
[0032] Reference Figure 1 , Figure 4 and Figure 5The outer wall of the bottle body 1 is provided with an external thread 11 for connecting the connecting sleeve 2, and the inner wall of the connecting sleeve 2 is provided with an internal thread 21. The internal thread 21 and the external thread 11 mesh with each other, and the connecting sleeve 2 can be installed on the outer wall of the bottle body 1 through the cooperation of the external thread 21 and the internal thread 11. In this embodiment, the connecting sleeve 2 moves downward when rotated clockwise and moves upward when rotated counterclockwise. The limiting plate 51 is set in an inclined shape. One end of the limiting plate 51 is fixedly connected to the inner wall of the closing ring 5, and the other end of the limiting plate 51 is suspended. The limiting plate 51 has elastic deformation capability. When the suspended end of the limiting plate 51 is squeezed, the limiting plate 51 will bend towards the inner wall of the closing ring 5. The outer wall of the bottle body 1 is provided with a limiting block 13 for blocking the limiting plate 51. The cross section of the limiting block 13 is set in a triangle. When the limiting plate 51 is pressed, the limiting block 13 will bend towards the inner wall of the closing ring 5. When the 51 ring rotates counterclockwise, the limiting block 13 will press the limiting plate 51 inward through the triangular inclined surface, so that the limiting plate 51 can pass through the obstruction of the limiting block 13 normally. This ensures that when the connecting sleeve 2 is installed with the bottle body 1, the limiting plate 51 can rotate normally with the connecting sleeve 2. The suspended end of the limiting plate 51 corresponds to the parallel end face of the triangle of the limiting block 13. When the closing ring 5 rotates counterclockwise, the limiting plate 51 will contact the triangular plane end of the limiting block 13 with its suspended end. In this way, the closing ring 5 will be restricted from passing through the obstruction of the limiting block 13, and thus the closing ring 5 cannot rotate counterclockwise. The inclined surface of the limiting block 13 corresponds to the upward direction of the external thread 11. When the operator attempts to rotate the connecting sleeve 2 to separate it from the bottle body 1, the limiting block 13 will block the movement of the limiting plate 51.
[0033] Reference Figure 2 , Figure 4 and Figure 5 The outer wall of the bottle body 1 is provided with a limiting ring 12 to restrict the upward movement of the limiting plate 51. The upper edge of the limiting ring 12 is arc-shaped. When the limiting plate 51 moves downward and contacts the limiting ring 12, it can pass through the limiting ring 12 through its own deformation. When the limiting plate 51 attempts to move upward, it will be restricted by the limiting ring 12 and cannot move upward. Both ends of the connecting strap 6 are connected with a bending strap 7 to guide the rotation of the bottle cap 3. The front end of the bending strap 7 is fixedly connected to the rear surface of the connecting sleeve 2, and the rear end of the bending strap 7 is fixedly connected to the rear surface of the connecting sleeve 2. The bending strap 7 itself is composed of two sets of triangular elastic pieces. It will keep itself in a bent state through its own elastic deformation. For example, when the bottle cap 3 is in the open state, the bending strap 7 will push the bottle cap 3 so that it will not rotate inward and close arbitrarily. The front surface of the connecting sleeve 2 is provided with a buckle groove 42 to facilitate the operator to lift the sealing buckle 4. Both ends of the sealing buckle 4 are provided with a bent edge 43 to facilitate the operator to lift the sealing buckle 4.
[0034] Working principle: When the whole device is placed normally, the bottle cap 3 is sleeved on the upper surface of the connecting sleeve 2, and the protruding plate 31 is inserted into the slot 41 of the closing buckle 4, so that the bottle cap 3 is locked and cannot be opened at will. The closing buckle 4 is connected to the connecting sleeve 2 through the connecting strip 45. The connecting sleeve 2 is installed on the bottle body 1 through the internal thread 21 and the external thread 11 of the bottle body 1. The closing ring 5 is sleeved on the outer wall of the bottle body 1, and the limiting plate 51 on its inner wall cooperates with the limiting block 13 on the outer wall of the bottle body 1 to restrict the rotation of the closing ring 5. The connecting strip 6 connects the connecting sleeve 2 and the bottle cap 3 to prevent the bottle cap 3 from being lost. The bending strip 7 is kept in a bent state so that the bottle cap 3 will not rotate inward to close at will when it is open.
[0035] When it is necessary to open the bottle cap 3, firstly, the operator's fingers hold the buckle groove 42 on the front surface of the connecting sleeve 2 and pinch the bent edges 43 on both sides of the sealing buckle 4. Then, the sealing buckle 4 can be lifted forcefully. Since the connecting strip 45 is integrally formed with the connecting sleeve 2 and the protrusion 44 has a larger connection area with the sealing buckle 4, the connecting strip 45 and the protrusion 44 are not easy to remain on the outer wall of the connecting sleeve 2 when the sealing buckle 4 is removed. After the sealing buckle 4 is lifted, the protrusion 31 disengages from the slot 41, and then the bottle cap 3 can be rotated to open it.
[0036] When it is necessary to remove the connecting sleeve 2, the operator needs to rotate the connecting sleeve 2. Since the inclined surface of the limiting block 13 is aligned with the upward direction of the external thread 11, when the connecting sleeve 2 is rotated counterclockwise in an attempt to separate from the bottle body 1, the limiting block 13 will block the movement of the limiting plate 51, preventing the closing ring 5 from rotating with the connecting sleeve 2. During the relative rotation of the connecting sleeve 2 and the closing ring 5, shear stress is generated. Combined with the upward pulling force of the connecting sleeve 2, the connecting sleeve 2 can be separated from the closing ring 5 with less effort, thus removing the connecting sleeve 2 from the outer wall of the bottle body 1.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
