Description

Technical Field

[0001] The present invention relates to the technical field of bottle caps, and more particularly to a quick-release cap and a bottle. Background Art

[0002] Anti-theft bottle caps are a common packaging form for bottle packaging and are widely used in daily life. Their sealing and anti-theft features can ensure the safety of food in the bottle. Consumers can check from the outside whether the anti-theft structure of the anti-theft bottle cap has been damaged, and then determine whether the bottle cap has been opened.

[0003] The existing rotating connection bottle caps, such as the mineral water caps on the market, are fixed to the bottle mouth by a threaded connection, and the bottle mouth thread is integrally formed with the bottle body. Therefore, when the cap is unscrewed, the bottle cap can be easily opened along the thread, and the anti-theft ring is automatically disconnected and remains on the bottleneck. This type of structure is simple and can be easily imitated by counterfeiters.

[0004] In addition, due to the complex structure of the existing anti-theft bottle caps, the upper cover and the lower cover need to be injection molded as one piece, and the upper cover and the lower cover cannot be produced separately and then combined, resulting in high mold manufacturing costs, high production costs, and high defective rates.

[0005] In summary, the anti-theft bottle caps in the prior art have the problems that some structures are too simple and easy to be imitated; while some structures are complicated and the manufacturing cost is high, and the upper cover and the lower cover can only be produced in an integrated manner during production.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0027] In the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, the first feature being "above", "above" and "above" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature. The terms "vertical", "horizontal", "left", "right", "above", "below" and similar expressions are for illustrative purposes only, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] See also Figure 1 , Figure 4 , Figure 5 and Figure 6The present invention provides a quick-release cover, including an upper cover 1 and a lower cover 2. The upper cover 1 is sleeved on the outside of the lower cover 2, and the upper cover 1 is rotatably connected to the lower cover 2. A plurality of claws 3 for clamping the bottle mouth are arranged on the lower edge of the lower cover 2, that is, the bottle mouth of the bottle is detachably connected to the quick-release cover of the present application. Any two adjacent claws 3 are connected by a connection component 4 that can be broken under force. A protrusion 5 is arranged on the connection component 4, and a groove 101 adapted to the protrusion 5 is opened at the bottom of the upper cover 1. The protrusion 5 is located inside the corresponding groove 101. The protrusion 5 is arranged so that when the upper cover 1 is rotated, the protrusion 5 is located inside the groove 101, and the protrusion 5 will also rotate relative to the lower cover 2 to break the connection component 4. A plurality of limit blocks 6 that can limit the upper edge of the upper cover 1 are arranged on the outer side surface of the lower cover 2. A plurality of first avoidance grooves 102 corresponding to the plurality of limit blocks 6 are provided on the upper edge of the upper cover 1. When the connection component 4 is not broken, the limit blocks 6 are limited on the upper edge of the upper cover 1, so that the upper cover 1 and the lower cover 2 cannot move radially or rotate relative to each other, so that the upper cover 1 always clamps all the claws 3, and all the claws 3 always clamp the bottle mouth of the bottle, that is, to make the claws 3 disengage from clamping the bottle mouth, the connection component 4 must be broken to make the claws 3 disengage from each other, and the inner wall of the upper cover 1 must be disengaged from clamping the claws 3. When the upper cover 1 rotates to the first angle, the connection component 4 is broken, the claws 3 are located inside the upper cover 1, and the upper cover 1 and the lower cover 2 can rotate relative to each other. At this time, since the limit blocks 6 are limited on the upper edge of the upper cover 1, the upper cover 1 and the lower cover 2 cannot move radially relative to each other. When the upper cover 1 is rotated to the second angle, each stop block 6 is moved above the corresponding first avoidance groove 102. At this time, the upper cover 1 is manually pulled to make the upper cover 1 move radially relative to the lower cover 2, so that the stop block 6 enters the first avoidance groove 102. At this time, the lower cover 2 moves downward relative to the upper cover 1 to make all the claws 3 disengage from the inner wall of the upper cover 1, so that the claws 3 are not subjected to external force, so that the claws 3 can be easily separated from the bottle mouth. Compared with the prior art, the quick-release cover of the present application has stronger anti-theft performance, and the upper cover 1 and the lower cover 2 are easy to install and can be produced separately, reducing the difficulty of production.

[0030] Optionally, the second angle is greater than the first angle.

[0031] In practical applications, the claw 3 may be an elastic claw 3. For example, the claw 3 made of plastic only needs to be able to deform under force, and this application does not limit this.

[0032] In an alternative embodiment, see Figure 1 , Figure 3 , Figure 4 and Figure 5In the present application, a pressing block 7 is arranged on the outer wall of the clamping claw 3, and a second avoidance groove 103 corresponding to the pressing block 7 and for the pressing block 7 to enter is opened on the lower edge of the upper cover 1. When the connecting assembly 4 is not disconnected, the pressing block 7 abuts against the inner wall of the upper cover 1, and the function of the pressing block 7 is to make the clamping claw 3 clamp the bottle mouth more firmly and enhance the clamping force of the clamping claw 3. When the limit block 6 is located in the first avoidance groove 102, the pressing block 7 is located inside the second avoidance groove 103, that is, when the connecting assembly 4 is broken, it is necessary to rotate the upper cover 1 relative to the lower cover 2 by a certain angle so that each limit block 6 goes to the top of the corresponding first avoidance groove 102. At this time, in order to pull the upper cover 1 more effortlessly and make the upper cover 1 move radially relative to the lower cover 2, it is necessary to locate the pressing block 7 inside the second avoidance groove 103 when the limit block 6 is located in the first avoidance groove 102, so that the pressing block 7 is no longer pressed by the inner wall of the upper cover 1, so that the user can pull the upper cover 1 more effortlessly and make the upper cover 1 move radially relative to the lower cover 2.

[0033] In an alternative embodiment, see Figure 1 , Figure 3 and Figure 5 The inner wall of the claw 3 radially protrudes inward to form a flange 10 for clamping the bottle mouth. In actual application, a circle of convex edges will be set at the bottle mouth. The present application uses the flange 10 to clamp the convex edge to make the clamping method of the quick release cover of the present application and the bottle mouth more stable.

[0034] In an alternative embodiment of the connection assembly 4, see Figure 1 and Figure 3 , the connecting assembly 4 includes an anti-theft block 41 and a connecting bridge 42. One end of the anti-theft block 41 is hinged to one of the claws 3 of any two adjacent claws 3, and the other end is hinged to the connecting bridge 42. The connecting bridge 42 is also hinged to the other claw 3 of any two adjacent claws 3. The protrusion 5 is arranged on the anti-theft block 41, and the connecting bridge 42 is broken by force. In actual application, the protrusion 5 is arranged on the anti-theft block 41, and the protrusion 5 is located inside the groove 101 of the upper cover 1, so that the connecting bridge 42 can be broken when the upper cover 1 rotates relative to the lower cover 2. In addition, the anti-theft block 41 is located directly below the lower edge of the upper cover 1 to limit the radial downward movement of the upper cover 1 relative to the lower cover 2.

[0035] In an alternative embodiment, see Figure 1 and Figure 6, the present application also provides a first anti-rotation rib 8 on one side of the first avoidance groove 102, and a second anti-rotation rib 9 on the other side; the first anti-rotation rib 8 and the second anti-rotation rib 9 are provided on the upper edge of the upper cover 1; the limit block 6 is located between the first anti-rotation rib 8 and the second anti-rotation rib 9. The provision of the first anti-rotation rib 8 and the second anti-rotation rib 9 allows the limit block 6 to only enter the corresponding first avoidance groove 102, and the pressing block 7 to only enter the corresponding second avoidance groove 103.

[0036] In an alternative embodiment, see Figure 2 In the present application, a first inclined section 11 is provided above the stop block 6. The distance between the end of the first inclined section 11 close to the upper cover 1 and the stop block 6 is smaller than the distance between the end of the first inclined section 11 far from the upper cover 1 and the stop block 6. The provision of the first inclined section 11 can make it easier for the upper cover 1 to be inserted into the lower cover 2.

[0037] See also Figure 1 , Figure 2 and Figure 5 A second inclined section 12 is provided inside the second avoidance groove 103. The distance between the end of the second inclined section 12 close to the upper edge of the lower cover 2 and the axis of the lower cover 2 is smaller than the distance between the end of the second inclined section 12 close to the lower edge of the lower cover 2 and the axis of the lower cover 2. The first inclined section 11 and the second inclined section 12 can form an oblique wedge shape. When the upper cover 1 is assembled into the lower cover 2, it only needs to align the first inclined section 11 with the second inclined section 12, and then press the upper cover 1 into the lower cover 2 to complete the installation, which is simple and quick.

[0038] The present application also provides a bottle, comprising a bottle body and the quick-release cover as described above; a plurality of the clamping claws 3 are clamped on the bottle mouth of the bottle body.

[0039] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
