Description

Technical Field

[0001] This invention relates to the field of medicine bottle technology, specifically to a medicine bottle and cap structure with child-proof opening function. Background Technology

[0002] Conventional medicine bottles typically consist of a bottle body and a cap positioned at the bottle opening. The locking mechanism between the bottle opening and the cap usually includes a surface-threaded screw connection or the bottle opening being inserted into the cap and secured by protrusions or grooves. These conventional structures are easy for children to operate; after a few tries, they can open the cap, posing a risk of medication use. While existing medicines have improved this issue by incorporating child-proof features, the unlocking mechanism is generally located on the cap, making it quite noticeable and easily spotted by children. Even after repeated attempts, the cap can still be opened.

[0003] For example, the authorized invention patent CN1 12340226A relates to the field of medicine bottle technology and discloses a safe medicine bottle to prevent children from accidentally ingesting medicines, including a bottle body, an inner cap, an outer cap, and an anti-accidental opening mechanism; the upper end of the bottle body is provided with a connecting part, and the outer peripheral wall of the connecting part is provided with an external thread; the inner peripheral wall of the inner cap is provided with an internal thread, and the internal thread is threadedly connected to the external thread, so that the inner cap is movably connected to the connecting part; the outer cap is fastened to the outer side of the inner cap, the outer side of the inner cap is provided with an annular protrusion, and the inner side of the outer cap is provided with an annular groove, and the annular groove is rotatably engaged with the annular protrusion; the anti-accidental opening mechanism is disposed between the inner cap and the outer cap, and is used to control the connection state and disconnection state of the inner cap and the outer cap. Although it provides a new type of bottle cap locking structure to improve the problem that children can easily open medicine bottles in the existing technology, which could lead to accidental ingestion of the medicine and thus pose certain safety hazards, the anti-accidental opening mechanism is located on the bottle cap and its anti-accidental opening rod is exposed on the bottle cap. Children can easily notice this and may unlock and open the bottle cap by repeatedly touching it. Furthermore, the anti-accidental opening mechanism can be damaged during the process of pulling, pressing, and twisting the anti-accidental opening rod, making it impossible to open the bottle cap.

[0004] In summary, existing medicine bottles complicate the unlocking mechanism and operation process, rather than improving the bottle structure based on children's limitations in using large objects. This means that there is still a possibility that children may accidentally open the medicine bottles, and the possibility of children accidentally opening the caps cannot be completely eliminated. Summary of the Invention

[0005] The purpose of this invention is to address the problem that existing medicine bottles do not have a stable cap to prevent children from opening, which poses a safety hazard when using the medicines inside. Therefore, this invention provides a medicine bottle and cap structure with a child-proof opening function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a medicine bottle and cap structure with child-proof opening function, comprising:

[0007] The bottle body has a first button groove on its side, which extends to the top surface of the bottle body through a first inner channel, and a stopper is provided at the bottle mouth.

[0008] The first button has an elastic sliding seal disposed within the first button groove;

[0009] A bottle cap is fitted onto the bottle opening and has a second inner channel inside. The lower end of the second inner channel extends to the bottom surface of the bottle cap and communicates with the upper end of the first inner channel. A second button slot is also provided laterally through the bottle cap, and the second inner channel communicates with the second button slot.

[0010] A float is floatingly disposed in the second inner channel at a position corresponding to the second button slot, and a second limiting ring is provided at the bottom of the float in the second inner channel;

[0011] The second button has an elastic sliding seal disposed within the second button groove;

[0012] A locking mechanism is disposed in the inner cavity of the bottle cap, at a position corresponding to the second button groove, and is used to abut against the bottle mouth to achieve locking and positioning of the bottle mouth and the bottle cap.

[0013] As a further description of the above technical solution:

[0014] The first button slot has a first limiting ring at the inner end of the first button, and a first elastic element is provided between the first button and the first limiting ring. The outer end of the first button has a stepped structure, and the outer end of the first button slot has a limiting inner edge that fits into the stepped structure.

[0015] As a further description of the above technical solution:

[0016] Several insertion guide blocks are provided on the outer side of the upper end face of the bottle body, and the insertion guide blocks are axially inserted into the slots on the bottom surface of the bottle cap.

[0017] As a further description of the above technical solution:

[0018] A sealing gasket is provided on the upper end face of the bottle body on the outside of the bottle mouth, and a through hole is provided on the sealing gasket to connect the first inner channel and the second inner channel.

[0019] As a further description of the above technical solution:

[0020] The second button has an I-shaped structure. The third limiting ring in the groove of the second button is sleeved on the recess in the middle of the second button. A second elastic element is provided between the outer end face of the third limiting ring and the recess.

[0021] As a further description of the above technical solution:

[0022] The locking mechanism includes an eccentric wheel, which is elastically and eccentrically rotatably connected to a rotating shaft inside the bottle cap. A notch is provided on the side of the bottle opening to fit into the side of the eccentric wheel.

[0023] As a further description of the above technical solution:

[0024] The rotating shaft passes through the through hole of the eccentric wheel, and a coil spring is embedded between the rotating shaft and the through hole. The two ends of the coil spring are respectively positioned on the rotating shaft and the through hole.

[0025] As a further description of the above technical solution:

[0026] The rotating shaft is provided with a limiting plate on the outside of the perforation of the eccentric wheel, and the limiting plate abuts against the end face of the eccentric wheel.

[0027] As a further description of the above technical solution:

[0028] The float has a lightweight magnetic shielding structure, and magnets are provided on the second button and the locking mechanism.

[0029] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0030] The medicine bottle and cap structure of this invention takes into account the limitations of large-sized objects for children. Through a multi-switch structure of a first button and a second button, a structural linkage unlocking design is achieved. When only a single button is pressed, the cap cannot be unlocked. Moreover, the buttons are embedded inside the medicine bottle. The two types of buttons are respectively located on the bottle body and the cap, making them difficult to notice. Several buttons with the same function are arranged around the circumference of the medicine bottle, so that pressing all buttons is required to unlock it. This increases the difficulty of opening the medicine bottle for children with small hands and achieves the function of preventing children from opening it. In use, first press the first button to reduce the space within the first and second inner channels, increasing internal pressure and lifting the float upwards, disengaging it from the second button slot. Then, press the second button to allow its inner end to pass through the second inner channel and second button slot, triggering the locking mechanism and unlocking the bottle body and cap. The cap can then be pulled off the bottle opening. When the cap is on the bottle body, first invert the cap, causing the float to move out of the second button slot due to its own weight and the air pressure created by the pressure difference on both sides. Then, press the second button and place the cap back on the bottle body. Releasing the second button causes it to automatically move outwards and reset, releasing its obstruction of the float, which then re-enters the middle of the second button slot, completing the locking process. This ensures that the bottle cap is difficult for children to open, regardless of how they grasp or position it. Once the method is understood, opening and closing the cap is simple, and the cap is securely positioned. Attached Figure Description

[0045] Example 1:

[0046] Please see Figure 1-6 This invention provides a technical solution: a medicine bottle and cap structure with child-proof opening function, comprising:

[0047] The bottle body 1 has a first button groove 11 on its side, the first button groove 11 extends to the top surface of the bottle body 1 through a first inner channel 12, and a stopper 14 is provided at the bottle mouth 13 of the bottle body 1.

[0048] The first button 2 is elastically and slidingly sealed within the first button groove 11;

[0049] A bottle cap 3 is fitted onto the bottle mouth 13, and a second inner channel 31 is provided inside it. The lower end of the second inner channel 31 extends to the bottom surface of the bottle cap 3 and communicates with the upper end of the first inner channel 12. A second button groove 32 is also provided laterally through the bottle cap 3, and the second inner channel 31 communicates with the second button groove 32.

[0050] A float 4 is floating in the second inner channel 31 at a position corresponding to the second button slot 32. A second limiting ring 33 is provided at the bottom of the float 4 in the second inner channel 31.

[0051] The second button 5 is elastically and slidingly sealed within the second button groove 32;

[0052] A locking mechanism is disposed in the inner cavity of the bottle cap 3 at a position corresponding to the second button groove 32. It is used to abut against the bottle mouth 13 to achieve locking and positioning of the bottle mouth 13 and the bottle cap 3.

[0053] The medicine bottle and cap structure of this invention takes into account the limitations of large-sized objects for children. It achieves a multi-switch design with a first button and a second button, enabling a linked unlocking mechanism. Pressing only a single button will not unlock the cap, and the buttons are embedded inside the bottle. The two types of buttons are located on the bottle body and cap respectively, making them difficult to notice. Several buttons with the same function are arranged around the circumference of the bottle, requiring all buttons to be pressed to unlock. This increases the difficulty for children with small hands to open the bottle, achieving a child-proof opening function. In use, pressing the first button first reduces the space within the first and second inner channels, increasing internal pressure and pushing the float upwards, disengaging it from the second button slot. Then, pressing the second button causes its inner end to pass through the second inner channel and the second button slot, triggering the locking mechanism and unlocking the bottle body and cap. The cap can then be pulled off the bottle opening. Pressing only the first button without using the second button will not trigger the locking mechanism, preventing unlocking. Pressing only the second button will also prevent unlocking due to the float's obstruction. When the bottle cap is on the bottle, first invert the bottle. This causes the float to move out of the second button slot due to its own weight and the air pressure created by the pressure difference on both sides. At this point, press the second button, then put the bottle cap back on the bottle. After releasing the second button, it will automatically move outward and reset due to its elastic force, releasing its obstruction of the float. The float will then be blocked again in the middle of the second button slot, completing the locking. However, when the medicine bottle is directly inverted, the float will not move out of the second button slot. In this case, it cannot be unlocked by pressing the second button alone. This achieves the effect of making it difficult for children to open the bottle cap no matter how they hold or position it. Moreover, once the method of use is understood, opening and closing the bottle cap is simple, and the bottle cap is securely positioned.

[0054] In this embodiment, the elastic installation method of the two buttons is as follows: A first limiting ring 17 is provided at the inner end of the first button 2 in the first button groove 11. A first elastic element 18 is provided between the first button 2 and the first limiting ring 17. The outer end of the first button 2 has a stepped structure, and the outer end of the first button groove 11 is provided with a limiting inner edge that fits into the stepped structure. The second button 5 has an I-shaped structure. A third limiting ring 36 in the second button groove 32 is fitted onto the recess in the middle of the second button 5. A second elastic element 37 is provided between the outer end face of the third limiting ring 36 and the recess. This improves the elastic assembly and stability of the buttons during use.

[0055] Several insertion guide blocks 16 are provided on the outer side of the upper end face of the bottle body 1. The insertion guide blocks 16 are axially inserted into the slots 35 on the bottom surface of the bottle cap 3. This enables the bottle cap 3 to be circumferentially positioned with the bottle body 1 after it is placed on the bottle mouth 13, and improves the convenience of the docking operation between the two.

[0056] The locking mechanism includes an eccentric wheel 6, which is elastically and eccentrically rotatably connected to a rotating shaft 34 inside the bottle cap 3. A notch 15 is provided on the side of the bottle mouth 13 to fit into the side of the eccentric wheel 6.

[0057] The rotating shaft 34 passes through the through hole 61 of the eccentric wheel 6, and a coil spring 38 is embedded between the rotating shaft 34 and the through hole 61. The two ends of the coil spring 38 are respectively positioned on the rotating shaft 34 and the through hole 61. A limiting plate 39 is provided on the outside of the through hole 61 of the eccentric wheel 6, and the limiting plate 39 abuts against the end face of the eccentric wheel 6. This improves the stability of the eccentric wheel 6 in its elastic rotational connection on the rotating shaft 34.

[0058] The working principle of a medicine bottle and cap structure with child-proof opening function in this embodiment includes: When in use, first press the first button 2 to reduce the space inside the first inner channel 12 and the second inner channel 31, and pressurize the inside to push the float 4 upward and disengage it from the second button slot 32. At this time, press the second button 5 to make its inner end pass through the second inner channel 31 and the second button slot 32 and link the locking mechanism to unlock the bottle body 1 and the cap 3. Then, the cap 3 can be pulled out from the bottle mouth 13.

[0059] The specific linkage between the second button 5 and the locking mechanism includes: when the bottle cap 3 is opened, the inner end of the second button 5 directly or indirectly contacts and pushes the side of the eccentric wheel 6, causing the eccentric wheel 6 to rotate along the rotating shaft 34 and disengage from the notch 15. At this time, the axial locking effect of the locking mechanism on the bottle mouth 13 and the bottle cap 3 is released, and the bottle cap 3 can be pulled out from the bottle mouth 13.

[0060] When the bottle cap 3 is placed on the bottle body 1, the bottle cap 3 is first inverted, so that the float 4 moves out of the range of the second button groove 32 due to its own weight and the air pressure formed by the pressure difference on both sides. At this time, the second button 5 is pressed, and the bottle cap 3 is placed on the bottle body 1. Then, the second button 5 is released, and it automatically moves outward and resets under the action of the elastic force. Its blocking effect on the float 4 is released, and the float 4 is blocked again in the middle of the second button groove 32. At this time, the effect of the second button 5 on the eccentric wheel 6 is released, and the eccentric wheel 6 automatically rotates and resets under the action of the elastic force and its side moves into the notch 15, completing the locking.

[0061] When only the first button 2 is pressed without using the second button 5, the locking mechanism cannot be activated, thus preventing unlocking. Similarly, pressing only the second button 5 results in the float 4 obstructing the movement, also preventing unlocking. When the medicine bottle is inverted, the float 4 remains within the range of the second button slot 32, making unlocking impossible with only the second button 5. This ensures that the bottle cap is difficult to open regardless of how a child holds or positions it. Furthermore, once the user understands the operation, opening and closing the cap is simple, and the cap is securely positioned.

[0062] Example 2:

[0063] Please see Figure 1 , 2 Based on the above embodiment one, preferably, a sealing gasket 7 is provided on the upper end face of the bottle body 1 outside the bottle mouth 13, and a through hole is provided on the sealing gasket 7 to connect the first inner channel 12 and the second inner channel 31. This achieves a seal at the joint of the first inner channel 12 and the second inner channel 31 when the bottle cap 3 is closed on the bottle body 1, thereby improving the stability of the pneumatic linkage between the first button 2 and the float 4.

[0064] Example 3:

[0065] Please see Figure 1 , 2 4. Based on the above embodiment one, preferably, the float 4 is a lightweight magnetic shielding structure, and magnets are provided on the second button 5 and the locking mechanism. The float 4 can be a lightweight structure containing magnetic shielding materials such as iron, steel, and nickel. It can be a hollow structure or a composite structure with a lightweight block body covered by a layer of magnetic shielding material. It needs to ensure that its density is low enough to allow it to levitate in air, while also possessing good magnetic shielding performance.

[0066] The working principle of a medicine bottle and cap structure with child-proof opening function in this embodiment includes: In this embodiment, the linkage between the second button 5 and the eccentric wheel 6 adopts a non-contact linkage based on magnetic effect. When the float 4 is within the range of the second button slot 32, the float 4 magnetically shields the magnetic field formed by the magnet in the second button 5 and the eccentric wheel 6, so that the elastic force of the coil spring 38 is greater than the magnetic force of the magnet, and the eccentric wheel 6 abuts against the notch 15 to achieve locking; when the float 4 rises and the second button 5 moves toward the eccentric wheel 6, the magnetic force on the eccentric wheel 6 is greater than the elastic force, and it rotates and disengages from the notch 15 to achieve unlocking.

[0067] In summary, due to the adoption of the above technical solution, the medicine bottle and cap structure with child-proof opening function of this embodiment has the following advantages compared with the prior art:

[0068] The medicine bottle and cap structure of this invention takes into account the limitations of large-sized objects for children. Through a multi-switch structure of a first button and a second button, a structural linkage unlocking design is achieved. When only a single button is pressed, the cap cannot be unlocked. Moreover, the buttons are embedded inside the medicine bottle. The two types of buttons are respectively located on the bottle body and the cap, making them difficult to notice. Several buttons with the same function are arranged around the circumference of the medicine bottle, so that pressing all buttons is required to unlock it. This increases the difficulty of opening the medicine bottle for children with small hands and achieves the function of preventing children from opening it. In use, first press the first button to reduce the space within the first and second inner channels, increasing internal pressure and lifting the float upwards, disengaging it from the second button slot. Then, press the second button to allow its inner end to pass through the second inner channel and second button slot, triggering the locking mechanism and unlocking the bottle body and cap. The cap can then be pulled off the bottle opening. When the cap is on the bottle body, first invert the cap, causing the float to move out of the second button slot due to its own weight and the air pressure created by the pressure difference on both sides. Then, press the second button and place the cap back on the bottle body. Releasing the second button causes it to automatically move outwards and reset, releasing its obstruction of the float, which then re-enters the middle of the second button slot, completing the locking process. This ensures that the bottle cap is difficult for children to open, regardless of how they grasp or position it. Once the method is understood, opening and closing the cap is simple, and the cap is securely positioned.
