Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, and in particular to a novel press-on cap. Background Technology

[0002] Existing screw-on caps typically consist of an outer cap and an inner screw cap. The inner screw cap is screwed inside the outer cap and connected to the bottle neck via threads. To open the cap, the user needs to press the outer cap firmly to engage the protruding parts of the outer and inner caps, allowing the inner cap to be easily unscrewed. The main purpose of this design is to prevent children from opening the cap unnecessarily, providing a degree of safety.

[0003] However, the existing screw caps have a relatively simple structure and function, making it difficult to meet the needs of different users. Although the structure of the outer cap and inner screw cap can effectively prevent children from opening them, their functions are too fixed and require a large amount of pressing force during normal use. Users must press the cap every time they open it, which makes the process cumbersome and lacks convenience and flexibility. Utility Model Content

[0004] This invention proposes a novel pressure-screw cap to solve the problem mentioned in the background art that existing pressure-screw caps can only be opened by applying pressure.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A novel press-on cap, comprising:

[0007] Inner screw cap;

[0008] The outer sleeve is connected to the inner sleeve and can move relative to the inner sleeve.

[0009] The inner rotating cover and the outer rotating sleeve are provided with a linkage structure, which can switch to at least the following two working states when the two move relative to each other axially:

[0010] In the first working state, the inner rotating cover and the outer rotating sleeve can achieve bidirectional synchronous rotation;

[0011] In the second working state, the inner rotating cover and the outer rotating sleeve can only rotate synchronously in the first direction, and they do not move together when rotating in the second direction.

[0012] Preferably, the linkage structure includes:

[0013] The inner convex teeth are located in the circumferential direction of the inner wall of the outer sleeve;

[0014] The externally protruding teeth are located in the circumferential direction of the outer wall of the inner screw cap and are matched with the internally protruding teeth.

[0015] Preferably, the linkage structure further includes:

[0016] The first meshing tooth is located in the circumferential direction of the inner wall of the outer sleeve;

[0017] The second meshing tooth is located in the circumferential direction of the outer wall of the inner screw cap and matches the first meshing tooth;

[0018] The first meshing tooth and the second meshing tooth each include a limiting surface on one side and a guide surface on the opposite side. When the first meshing tooth and the second meshing tooth approach each other and are in contact with each other through the limiting surface, meshing transmission can be achieved. When the first meshing tooth and the second meshing tooth approach each other and are in contact with each other through the guide surface, they slip off from each other and the linkage is broken.

[0019] Preferably, there is an axial gap between the first meshing tooth and the inner convex tooth, and the second meshing tooth and the outer convex tooth are within the gap range when they are not in a linkage state.

[0020] Preferably, the inner wall of the outer sleeve is formed with a convex ring at the upper and lower ends of the inner convex tooth, and the inner diameter of the convex ring is smaller than the tip circle diameter of the second meshing tooth.

[0021] Preferably, the upper and lower surfaces of the convex ring are both formed with sloping surfaces, and the thickness of the convex ring gradually increases from the position near the center of the outer sleeve to the position far away from the center of the outer sleeve.

[0022] Preferably, the inner screw cap has an internal thread.

[0023] Preferably, the outer sleeve is a sleeve-type structure with openings at both ends.

[0024] Preferably, the outer wall of the outer sleeve is provided with an anti-slip structure.

[0025] Preferably, the inner screw cap is transparent or semi-transparent.

[0026] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0027] This invention achieves synchronous or limited rotation of the inner cap and outer sleeve under different working conditions. This not only retains the safety function of preventing children from opening the bottle, but also eliminates the need for users to press the cap every time they open it under normal use. This greatly simplifies the operation and improves the convenience and flexibility of use. Attached Figure Description

[0038] 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.

[0039] As shown in the figure, a novel press-on cap includes:

[0040] Inner screw cap 1;

[0041] The outer sleeve 2 is sleeved and connected to the inner sleeve 1, and can move relative to the inner sleeve 1. The inner sleeve 1 and the outer sleeve 2 can move relative to each other along the axial direction and can also rotate relative to each other around their axis.

[0042] The inner rotating cover 1 and the outer rotating sleeve 2 are provided with a linkage structure, which can switch to at least the following two working states when the two move relative to each other axially:

[0043] In the first working state, the inner rotating cover 1 and the outer rotating sleeve 2 can achieve bidirectional synchronous rotation;

[0044] In the second working state, the inner rotating cover 1 and the outer rotating sleeve 2 can only rotate synchronously in the first direction, and the two do not move together when rotating in the second direction.

[0045] In addition, this embodiment also has a third working state, that is, the inner rotating cover 1 and the outer rotating sleeve 2 can rotate relative to each other in any direction in a non-linkage state, and there is no linkage between the two.

[0046] In this example, the linkage structure includes:

[0047] The inner convex teeth 201 are arranged in the circumferential direction of the inner wall of the outer rotating sleeve 2. Specifically, there are multiple inner convex teeth 201, which are evenly distributed around the center of the outer rotating sleeve 2.

[0048] The outer protruding teeth 101 are arranged in the circumferential direction of the outer wall of the inner rotating cover 1 and match the inner protruding teeth 201. Similarly, there are multiple outer protruding teeth 101, which are evenly distributed around the center of the outer rotating sleeve 2.

[0049] When the inner screw cap 1 and the outer screw sleeve 2 move relative to each other along the axial direction to the first working state described above, the inner protruding tooth 201 and the outer protruding tooth 101 can mesh, thereby driving the inner screw cap 1 to rotate synchronously when the outer screw sleeve 2 rotates forward or backward. This usage state is suitable for occasions where bottle caps need to be opened and closed frequently without considering children. It can achieve the purpose of smoothly opening or closing the bottle cap without applying additional axial pressure, thus improving the convenience of operation.

[0050] It is understandable that the internal convex tooth 201 and the external convex tooth 101 can also be designed as a single tooth structure, etc.

[0051] In this example, the linkage structure also includes:

[0052] The first meshing tooth 202 is arranged in the circumferential direction of the inner wall of the outer sleeve 2, and multiple teeth are arranged in the circumferential direction of the outer sleeve 2 and are evenly distributed.

[0053] The second meshing tooth 102 is arranged in the circumferential direction of the outer wall of the inner screw cover 1 and matches the first meshing tooth 202. Similarly, multiple teeth are arranged in the circumferential direction of the inner screw cover 1 and are evenly distributed.

[0054] Both the first meshing tooth 202 and the second meshing tooth 102 include a limiting surface 3 on one side and a guide surface 4 on the opposite side. When the first meshing tooth 202 and the second meshing tooth 102 approach each other and are in contact with each other by the limiting surface 3, meshing transmission can be achieved. When the first meshing tooth 202 and the second meshing tooth 102 approach each other and are in contact with each other by the guide surface 4, they slip off from each other and the linkage is broken. In this example, the first meshing tooth 202 and the second meshing tooth 102 adopt a ratchet tooth structure to achieve the function of unidirectional synchronous rotation. In this example, the limiting surface 3 of the first meshing tooth 202 and the second meshing tooth 102 is set parallel to the central axis of the outer rotating sleeve 2. In addition, it can also be designed as a structure with a certain tilt angle.

[0055] Specifically, there is an axial gap between the first meshing tooth 202 and the inner convex tooth 201. When the second meshing tooth 102 and the outer convex tooth 101 are not in a linkage state, they are located within the gap range. In this state, the outer rotating sleeve 2 and the inner rotating cover 1 can be rotated relative to each other when the outer rotating sleeve 2 is rotated in any direction.

[0056] In another embodiment, the second meshing tooth 102 and the outer protruding tooth 101 can also be designed with a gap along the axial direction, in which the first meshing tooth 202 and the inner protruding tooth 201 are located in the gap when not in a linkage state.

[0057] Specifically, a convex ring 203 is formed on the inner wall of the outer sleeve 2 at the upper and lower ends of the inner convex tooth 201. The inner diameter of the convex ring 203 is smaller than the tooth tip circle diameter of the second meshing tooth 102. The purpose of setting the convex ring 203 is, on the one hand, to prevent the inner convex tooth 201 and the outer convex tooth 101 from easily achieving linkage. Only when the user applies a certain axial force, forcing the inner sleeve 1 or the outer sleeve 2 to undergo a certain deformation, can the outer convex tooth 101 pass over the convex ring 203 and mesh with the inner convex tooth 201. On the other hand, it is to prevent the two from easily disengaging when the outer convex tooth 101 and the inner convex tooth 201 are meshing with each other, thus achieving a limiting effect in two aspects.

[0058] In this example, the convex ring 203 is arranged in a ring shape along the inner wall of the outer sleeve 2. It can be understood that, in order to achieve the purpose of limiting, the convex ring 203 can also adopt a segmented structure design.

[0059] Specifically, the upper and lower surfaces of the convex ring 203 are both formed with sloped surfaces 2031. The thickness of the convex ring 203 gradually increases from the position near the center of the outer sleeve 2 to the position far away from the center of the outer sleeve 2. With this setting, the sloped surfaces 2031 can play a certain guiding role and prevent the interference area from being too large, which would cause the outer convex tooth 101 and the inner convex tooth 201 to be unable to cooperate.

[0060] Specifically, the inner screw cap 1 has an internal thread 103 for connecting to the bottle mouth.

[0061] Specifically, the outer sleeve 2 is a sleeve-type structure with openings at both ends. This design reduces material usage and production costs, while also allowing the inner cap 1 to protrude from the opening of the outer sleeve 2, thus enabling more functional extensions and increasing playability. For example, when the entire cap is screwed off from the bottle mouth, the inner cap 1, due to its protruding structure, can be manipulated by fingers, achieving a spinning motion similar to a finger spinner. This enhances the product's fun and interactivity, improves the user experience, and is particularly suitable for children or young users.

[0062] Specifically, the outer wall of the outer sleeve 2 is provided with an anti-slip structure 204. In this example, the anti-slip structure 204 is a groove-shaped structure opened along the axial direction of the outer wall of the outer sleeve 2. In addition, the anti-slip structure 204 can also adopt a shape such as frosted or oblique rolling groove, and anti-slip film, anti-slip rubber, or sprayed anti-slip material can be added to the outer wall of the outer sleeve 2.

[0063] Specifically, the inner screw cap 1 is transparent or semi-transparent. This design allows the contents of the bottle to be clearly seen from the outside through the inner screw cap 1, enabling quick identification of the type, quantity, and color of the items inside. Furthermore, labels of different colors and patterns can be placed on the inner screw cap 1 for marking and differentiation.

[0064] This novel press-lock cap, through the linkage structure between the inner screw cap 1 and the outer screw sleeve 2, can switch between different working states during axial relative movement: in normal use, bidirectional rotation opening and closing is achieved through the mutual meshing of the inner convex tooth 201 and the outer convex tooth 101, simplifying the operation process; while in the safety protection state, only unidirectional rotation is allowed to prevent children from accidentally opening it; this structure takes into account both safety and convenience, and the outer screw sleeve 2 is a sleeve-type structure with openings at both ends, reducing material costs and providing playability and customization, thereby improving user experience and product added value.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
