Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, specifically a child-safe press-type bottle cap. Background Technology

[0002] Bottle caps are an important packaging structure used to seal bottles. Common bottle caps are sealed or opened by threads that match the bottle opening. Child-safe press-type bottle caps, also known as screw caps, are specially designed to prevent children from opening containers containing medicines, chemicals, or other hazardous materials, thereby avoiding accidents such as accidental ingestion or poisoning.

[0003] However, the existing technology still has some shortcomings. The existing technology achieves the opening of the bottle cap through a two-action process of pressing and rotating the cap. Although this method makes it impossible for most young children to open the bottle, some children may have great curiosity. If they frequently see their parents performing the same action, they may accidentally open the bottle cap by imitating the adults' actions, causing the medicine inside the bottle to fall out accidentally. The child may then imitate the parents and swallow the medicine, thus causing the danger of accidental ingestion. Therefore, we provide a child-safe pressing bottle cap to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a child-safe press-type bottle cap.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a child-safe press-type bottle cap, comprising an outer bottle cap and an inner bottle cap, wherein the outer bottle cap and the inner bottle cap are rotatably connected, and a limiting tooth is fixedly connected to the inner top of the outer bottle cap; a limiting groove is formed on the top of the inner bottle cap, and the limiting tooth is adapted to the limiting groove; a slip ring is fixedly connected to the outside of the inner bottle cap, and two limiting blocks are fixedly connected to the inner wall of the inner bottle cap respectively; a sliding groove is formed on the inner wall of the outer bottle cap, and the outer wall of the slip ring is slidably connected to the inside of the sliding groove; two directional markers are fixedly connected to the inner bottle cap respectively, and a bottle body is threadedly connected to the inner wall of the inner bottle cap; two directional markers are fixedly connected to the outer surface of the bottle body respectively, and two support frames are fixedly connected to the outer surface of the bottle body respectively; a limiting mechanism is hinged to the inner side of the support frame, and an elastic mechanism is fixedly connected to the bottom of the limiting mechanism.

[0006] The aforementioned limiting mechanism includes a connecting rod, an abutment block, a synchronizing bar, a pull block, and a pull ring. One end of the connecting rod is fixedly connected to one end of the abutment block, and the bottom end of the connecting rod is fixedly connected to the top end of the synchronizing bar. The bottom of the synchronizing bar is fixedly connected to one end of the pull block, and the bottom of the pull block is fixedly connected to the top end of the pull ring.

[0007] As described above, one end of the connecting rod is hinged to the inner side of the support frame, and one side of the connecting rod passes through the inner bottle cap and is slidably connected to the outer wall of the bottle body.

[0008] As described above, the end of the abutment block furthest from the connecting rod is in close contact with the end of the limiting block.

[0009] The elastic mechanism described above includes a sleeve, a spring, and a rod. One end of the rod is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the inside of the sleeve.

[0010] As described above, a mounting base is fixedly connected to the bottom end of the sleeve, and one end of the mounting base is fixedly connected to one end of the support frame.

[0011] As described above, the top end of the sleeve rod is fixedly connected to the bottom end of the connecting rod, and the bottom end of the sleeve rod is slidably connected to the inner wall of the sleeve.

[0012] Compared with existing technologies, this child-safe press-type bottle cap has the following advantages: I. This utility model constructs a new safe opening method for the inner bottle cap by adding a contact block to unlock and limit the limiting block. It works in conjunction with the original limiting tooth-limiting groove medicine bottle opening structure, which not only improves the overall safety of medicine storage, but also effectively prevents the risk of children accidentally opening the medicine bottle.

[0013] II. This utility model utilizes the dual function of the spring. When extended, the spring provides power to the sleeve rod, which drives the contact block into the inner bottle cap through the connecting rod to complete the limiting. The entire process requires no additional external power source. When compressed, the spring enables the sleeve rod to adapt to human pulling force, effectively buffering the pulling force of different operators, thereby avoiding damage to the connecting structure at the connecting rod due to excessive force.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0017] 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.

[0018] like Figure 1-4 As shown, this utility model provides a technical solution: a child-safe press-type bottle cap, including an outer bottle cap 1 and an inner bottle cap 2, which are rotatably connected. A limiting tooth 3 is fixedly connected to the inner top of the outer bottle cap 1. The outer bottle cap 1 has anti-slip textures on its exterior to increase friction with the user's hand, thus saving the user's effort. A limiting groove 4 is formed on the top of the inner bottle cap 2, and a sealing ring is provided inside the inner bottle cap 2 to prevent air from entering through the gap between the inner bottle cap 2 and the bottle body 11, thereby improving the sealing of the medicine. The limiting tooth 3 and the limiting groove 4 are compatible. The outer bottle cap 1 is fixedly connected to a slip ring 5, and the inner wall of the inner bottle cap 2 is fixedly connected to two limiting blocks 6 respectively. The inner wall of the outer bottle cap 1 is provided with a sliding groove 7. The outer wall of the slip ring 5 is slidably connected to the inside of the sliding groove 7. The inner bottle cap 2 is fixedly connected to two directional markers 10 respectively, and the inner wall of the inner bottle cap 2 is threadedly connected to a bottle body 11. The outer surface of the bottle body 11 is fixedly connected to two directional markers 12 respectively, and the outer surface of the bottle body 11 is fixedly connected to two support frames 13 respectively. The inner side of the support frame 13 is hinged to a limiting mechanism 8, and the bottom of the limiting mechanism 8 is fixedly connected to an elastic mechanism 9. The outer bottle cap 1 is made of transparent material, allowing users to easily observe the inner bottle cap 2 inside. Users can see the arrow markings on the inner bottle cap 2 (marker 10). Clockwise rotation of the arrow indicates the tightening direction. To open the inner bottle cap 2, it needs to be rotated counter-clockwise. When the arrow markings 10 and 12 on the bottle body 11 are in the same column, immediately pull down the limiting mechanism 8 and press to rotate the inner bottle cap 2, ultimately causing it to separate from the bottle body 11. The arrow markings 10 and 12 not only indicate the tightening or loosening direction to the user but also remind them that when the arrow markings 10 and 12 are in the same column, pulling down the limiting mechanism 8 releases the resistance block 802 from the limiting block 6, and then pressing down again... The inner bottle cap 2 can be opened and the medicine removed by pressing and rotating. The opening of the inner bottle cap 2 by pressing and rotating further enhances the safety of children in opening the inner bottle cap 2. The upper section of the bottle body 11 and the upper section of the inner bottle cap 2 are both provided with a small number of threaded grooves. The upper section of the inner bottle cap 2 is provided with internal threads, and the upper section of the bottle body 11 is provided with external threads. The internal threads and external threads are compatible. The internal threads of the upper section of the inner bottle cap 2 are located above the limiting block 6. The internal threads are located in this position so as not to affect the normal rotation of the limiting block 6 inside the inner bottle cap 2. After the small number of internal threads of the inner bottle cap 2 have been rotated, the limiting block 6 and the abutment block 802 are in contact. At this time, the first directional marker 10 and the second directional marker 12 are in the same column, thus prompting the user to operate the limiting mechanism 8 to open the inner bottle cap 2.

[0019] like Figure 1 and Figure 4 As shown, the limiting mechanism 8 includes a connecting rod 801, an abutment block 802, a synchronizing bar 803, a pull block 804, and a pull ring 805. One end of the connecting rod 801 is fixedly connected to one end of the abutment block 802, and the bottom end of the connecting rod 801 is fixedly connected to the top end of the synchronizing bar 803. The bottom of the synchronizing bar 803 is fixedly connected to one end of the pull block 804, and the bottom of the pull block 804 is fixedly connected to the top end of the pull ring 805. One end of the connecting rod 801 is hinged to the inner side of the support frame 13. One side of the connecting rod 801 passes through the inner bottle cap 2 and is slidably connected to the outer wall of the bottle body 11. The end of the abutment block 802 away from the connecting rod 801 is tightly attached to one end of the limiting block 6.

[0020] By restricting or releasing the limiting block 6 through the contact block 802, the inner bottle cap 2 is closed or opened. By adding a safe way to open the inner bottle cap 2 and combining it with the opening method of the medicine bottle by the limiting tooth 3 and the limiting groove 4, the safety of medicine storage is improved and the phenomenon of children accidentally opening medicine bottles is further reduced.

[0021] like Figure 1 and Figure 4As shown, the elastic mechanism 9 includes a sleeve 901, a spring 902, and a sleeve rod 903. One end of the sleeve rod 903 is fixedly connected to one end of the spring 902, and the other end of the spring 902 is fixedly connected to the inside of the sleeve 901. A mounting base 14 is fixedly connected to the bottom end of the sleeve 901, and one end of the mounting base 14 is fixedly connected to one end of the support frame 13. The top end of the sleeve rod 903 is fixedly connected to the bottom end of the connecting rod 801, and the bottom end of the sleeve rod 903 is slidably connected to the inner wall of the sleeve 901.

[0022] Spring 902 has extension and compression functions for sleeve rod 903. When spring 902 is extended, sleeve rod 903 provides power for the abutment block 802 to enter the inner bottle cap 2 through connecting rod 801. The limiting action of abutment block 802 can be completed without an additional external power source. When spring 902 is compressed, sleeve rod 903 cooperates with manual pulling of abutment block 802 to perform adaptive compression, which can buffer the pulling force of different operators and avoid damage to the connecting structure at connecting rod 801 due to excessive operating force.

[0023] Working principle: First, when the inner bottle cap 2 needs to be opened, press down on the outer bottle cap 1 so that the limiting teeth 3 of the outer bottle cap 1 insert into the limiting groove 4 at the top of the inner bottle cap 2. At this time, the outer bottle cap 1 and the inner bottle cap 2 are an integral structure. Second, rotate the outer bottle cap 1 counterclockwise. Observe whether the direction indicator 10 is rotating to determine whether the inner bottle cap 2 is rotating. When the direction indicator 10 and the direction indicator 2 12 are in the same column, pull down the pull ring 805. The pull ring 805 drives the pull block 804 to move downward. At this time, the pull block 804 drives the connecting rod 801 to move downward through the synchronous bar 803, and then the connecting rod 801 drives the abutment. Block 802 moves downward, causing the abutment block 802 to move away from one end of the limiting block 6, thereby releasing the restriction on the limiting block 6 and opening the inner bottle cap 2. Subsequently, as the connecting rod 801 drives the abutment block 802 to move downward, the connecting rod 801 presses the sleeve rod 903, causing the sleeve rod 903 to be compressed within the sleeve 901 by the spring 902. Conversely, the natural extension of the spring 902 causes the sleeve rod 903 to press the connecting rod 801, causing the connecting rod 801 to rise and drive the abutment block 802 to spring back into the inner bottle cap 2. This, in turn, re-limits the inner bottle cap 2 by the limiting block 6, thereby tightening the inner bottle cap 2 over the bottle body 11.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
