DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0032] Please refer to Figure 1-9 ,in, Figure 1 A schematic structural diagram of a first embodiment of a child-resistant bottle cap for a container provided by the present invention; Figure 2 for Figure 1 A schematic diagram of the disassembly of the outer cover shown; Figure 3 for Figure 2 A schematic diagram of the structure of the bottom portion of the outer cover shown; Figure 4 for Figure 2 A schematic diagram of the structure of the inner cover part shown; Figure 5 for Figure 2 A schematic diagram of the structure when the inner cover and the outer cover are joined together; Figure 6 for Figure 5 A schematic diagram of the cross-sectional structure of the outer cover before being pressed; Figure 7 for Figure 6 A schematic diagram of the cross-sectional structure of the outer cover after being pressed; Figure 8 for Figure 2 The structural diagram of the anti-theft component part shown; Fig. 9 for Figure 8 The schematic diagram of the structure after the anti-theft ring 51 and the anti-theft ring 52 are separated. The child-proof bottle cap of the container comprises: an inner cap 1 and an outer cap 2; a flexible convex piece 3, the flexible convex piece 3 is fixed to the top of the inner wall of the outer cap 2; a protrusion assembly 4, the protrusion assembly 4 is fixed to the top of the inner cap 1, the protrusion assembly 4 comprises a fixing ring 41, the inner surface of the fixing ring 41 is connected to a second protrusion 43 through a first protrusion 42; and a press-fit protrusion 11, the press-fit protrusion 11 is fixed to the top of the inner wall of the outer cap 2.

[0033] The second protrusion 43 is matched with the flexible protrusion 3 on the inner surface of the outer cover; the first protrusion 42 is matched with the press-fitting protrusion 11 on the inner surface of the outer cover.

[0034] There are corresponding press-fitting devices 11 at the top of the fixing ring 41 and the bottom of the inner wall of the outer cover 2, which facilitates the outer cover 2 and the inner cover 1 to be pressed together. The grooves inside the outer cover 2 and the grooves outside the inner cover 1 are designed to correspond to each other, so that the outer cover 2 fits on the top of the inner cover 1 through friction, and can prevent the inner cover 1 from detaching from the outer cover 2 when the cover is screwed.

[0035] The inner cover 1 is arranged inside the outer cover 2, and the inner cover 1 and the outer cover 2 are matched.

[0036] The fixing ring 41 is fixed to the top of the inner cover 1 , and the second protrusion 43 is matched with the flexible protrusion 3 .

[0037] Preferably, a total of four second bumps 43 are provided, and a total of eight first bumps 42 are provided.

[0038] When the outer cover 2 is pressed downward toward the bottle, the flexible protrusion 3 will drop to the connection between the second protrusion 43 and the top base of the inner cover 2 .

[0039] When screwing the cover, the outer cover 2 is pressed downward to fully fit the outer cover 2 onto the inner cover 1, and the outer cover 2 is rotated in the clockwise direction at the same time (preferably clockwise, and can also be designed to rotate counterclockwise according to actual needs, as long as the connection between the outer cover 2 and the inner cover 1 is satisfied), and the flexible protrusion 3 is against the connection between the second protrusion and the top base of the inner cover 2. In addition, the crimping protrusion 11 is inserted between the two first protrusions 42, and the fixing ring 41 is also inserted into the inner groove of the outer cover to lock the inner and outer covers. In addition to increasing the twisting force transmitted from the outer cover to the inner cover, it can also prevent the flexible sheet protrusion 3 from being broken due to excessive force.

[0040] An anti-theft component 5 is provided at the bottom of the inner cover 1 , and the anti-theft component 5 includes an anti-theft circle 51 and an anti-theft ring 52 . The anti-theft circle 51 and the anti-theft ring 52 are connected via a connecting bridge 53 . An indication label 6 is provided on the top of the outer cover 2 .

[0041] By designing the anti-theft ring 52, the bottle cap has a firm seal, good leak-proof and anti-theft performance. After the package is opened, the connecting bridge breaks and the anti-theft ring 52 is difficult to return to its original position, which can effectively prevent the contents in the bottle from being contaminated by bacteria and replaced. The indicator label 6 can indicate the operation of opening the bottle cap 2.

[0042] There is a locking device on the outer cover 2 to prevent the inner cover 1 from being removed from the outer cover 2, in order to prevent the outer cover 2 and the inner cover 1 from being easily separated, and then the inner cover 1 is directly touched, which loses the child-proof opening function. The locking device to prevent the anti-theft component 5 from being removed from the inner cover 1 is designed so that when the inner cover 1 is opened, the anti-theft ring 51 is screwed out along with the inner cover 1, while the anti-theft ring 52 continues to be stuck on the locking ring of the container, thereby causing the connecting bridge 53 to break, ensuring that the anti-theft ring 52 is separated.

[0043] Tightening the lid: The first method: when the outer lid 2 is not pressed downward toward the bottle, but only the lid is twisted in the direction of the flexible protrusion 3, the flexible protrusion 3 is embedded in the connection between the second protrusion 43 and the base of the inner lid, driving the inner lid to rotate in the same direction, thereby tightening the inner lid 1; The second method: after the outer lid 2 is pressed downward toward the bottle, the crimping mating protrusion 11 of the outer lid 2 is embedded between the two first protrusions 42, and when the lid is twisted in the direction of the flexible protrusion 3, the flexible protrusion 3 is embedded in the connection between the second protrusion 43 and the base of the inner lid, driving the inner lid to rotate in the same direction, thereby tightening the inner lid 1. This design can prevent the flexible protrusion 3 from being twisted off by a strong torque.

[0044] When the outer cover 2 is not pressed downward toward the bottle, the flexible protrusion 3 forcibly separates the press-fitting protrusion 11 and the first protrusion 42 .

[0045] The working principle of the child-resistant bottle cap of the container provided by the present invention is as follows:

[0046] When the bottle cap needs to be opened, the inner cap is loosened. When the outer cap is not pressed downward toward the bottle body, the flexible protrusion 3 forcibly separates the crimping protrusion 11 and the first protrusion 42 that loosen the cap. When the cap is twisted in the opposite direction of the direction of the flexible protrusion 3, the design of the flexible protrusion 3 ensures that the flexible protrusion 3 cannot be embedded in the connection between the second protrusion 43 and the base of the inner cap, resulting in the outer cap being unable to drive the inner cap to rotate, and thus being unable to loosen the inner cap. Only when the outer cap is pressed downward toward the bottle body, so that the crimping protrusion 11 of the outer cap is embedded between the two first protrusions 42 and the fixing ring, and then the outer cap is twisted in the opposite direction of the direction of the flexible protrusion 3, can the outer cap drive the inner cap to rotate in the same direction, thereby twisting the inner cap.

[0047] Compared with the related art, the child-resistant bottle cap for the container provided by the present invention has the following beneficial effects:

[0048] By dividing the bottle cap into an outer cover 2 and an inner cover 1, the inner cover 1 is used to seal bottles or other containers that need to be closed. When the outer cover 2 is directly rotated, the inner cover 1 will not rotate with the outer cover 2. Only when the outer cover 2 is pressed down and then rotated, can the inner cover 1 be driven to rotate, which makes it convenient to open the bottle cap and prevents children from accidentally opening the bottle cap. By using the flexible protrusion 3 and the second protrusion 43 in combination, and the crimping protrusion 11 and the first protrusion 42 in combination, the axial pushing stroke and force of the outer cover toward the inner cover can be increased, thereby preventing the risk of children opening the bottle cap. In addition, it also reduces the risk of the inner cover and the outer cover being engaged due to misoperation, resulting in the cover being accidentally opened.

[0049] Second embodiment

[0050] See also Fig.10 , Fig.11 and Fig.12 Based on the child-resistant bottle cap for a container provided in the first embodiment of the present application, the second embodiment of the present application provides another child-resistant bottle cap for a container. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0051] Specifically, the difference of the child-resistant bottle cap of the container provided in the second embodiment of the present application is that the child-resistant bottle cap of the container also includes a connecting device 7, the connecting device 7 includes a connecting column 71, the outer surface of the connecting column 71 is provided with an annular groove 72, and a bottom outer ring 73 is rotatably connected to the connecting column 71, the top of the bottom outer ring 73 is fixedly connected with a vertical rod 74 and a tension spring 75, the top of the tension spring 75 is fixedly connected with a T-shaped sleeve 76, and the top of the inner wall of the annular groove 72 is fixedly connected with a positioning hole 77; a limiting component 8, the limiting component 8 is arranged on one side of the inner wall of the annular groove 72, the limiting component 8 includes a groove 81, the bottom of the inner wall of the groove 81 is fixedly connected with a sliding rod 82, and a movable plate 83 is slidably connected to the sliding rod 82; a driven component 9, the driven component 9 is fixed to one side of the inner wall of the outer cover 2, the driven component 9 includes an arc-shaped movable plate 91, and the top of the arc-shaped movable plate 91 is provided with a through hole 92.

[0052] The fixing ring 41 and the inner cover 1 are connected by the connecting column 71 , so that when the fixing ring 41 rotates, the inner cover 1 can still be driven to rotate through the connecting column 71 .

[0053] The connecting column 71 is fixedly connected to the top of the inner cover 1, and the top of the connecting column 71 is fixedly connected to the fixing ring 41. The tension spring 75 is sleeved on the outer surface of the vertical rod 74. The top of the vertical rod 74 is located inside the T-shaped sleeve 76. The T-shaped sleeve 76 and the positioning hole 77 are adapted to each other.

[0054] The top of the vertical rod 74 is located inside the T-shaped sleeve 76 .

[0055] The groove 81 is opened on one side of the inner wall of the annular groove 72, the top of the sliding rod 82 passes through the movable plate 83 and is fixedly connected to the top of the inner wall of the groove 81, one end of the movable plate 83 is fixedly connected to the T-shaped sleeve 76, and there are two limit assemblies 8, which are respectively arranged on both sides of the connecting column 71.

[0056] The slide bar 82 passes through the movable plate 83 to ensure that the movable plate 83 can only rotate in the vertical direction.

[0057] The arc-shaped movable plate 91 is fixed to one side of the inner wall of the outer cover 2, the top of the T-shaped sleeve 76 passes through the through hole 92 and extends to the outside of the arc-shaped movable plate 91, and there are two driven components 9, which are respectively fixed to the two sides of the inner wall of the outer cover 2.

[0058] The tension spring 75 is in a contracted state at this time, exerting an upward thrust on the arc-shaped movable plate 91 .

[0059] Compared with the related art, the child-resistant bottle cap for the container provided by the present invention has the following beneficial effects:

[0060] The arc-shaped movable plate 91 is pushed upward by the tension spring 75, and the arc-shaped movable plate 91 bears the pressure on the outer cover 2, so that a greater force is required to press the outer cover 2 downward to press the flexible protrusion 3 between the first protrusion 42 and the second protrusion 43, thereby improving the protection against misoperation by children;

[0061] At this time, when the outer cover 2 is rotated, the second protrusion 43 is pushed by the flexible protrusion 3 to drive the inner cover 1 to rotate together. The T-shaped sleeve 76 can also be pushed by the arc-shaped movable plate 91. The T-shaped sleeve 76 pushes the slide bar 82 through the movable plate 83, so that the connecting column 71 drives the inner cover 1 to rotate. Through the joint action of the slide bar 82 and the flexible protrusion 3, and the torque resistance of the bottle cap, the inner cover 1 can still be removed even if the flexible protrusion 3 is broken.
