Description

Technical Field

[0001] The embodiments of this utility model relate to the field of bottle cap locking technology, specifically, to a child-safe locking medicine bottle cap. Background Technology

[0002] The background technology for safety lock medicine bottle caps stems from the serious risk of children accidentally ingesting medication and the inadequacies of existing packaging designs. Traditional medicine bottles generally use a simple threaded structure that children can easily open.

[0003] According to a public announcement (announcement number: CN212140939U), when the first latch is located in the first groove and / or the second latch is located in the second groove, the lower end face of the safety cap is pressed against the upper edge of the bottle body, sealing the bottle body together with the safety cap, preventing the medicine from being removed. To open the bottle, simply rotate the sealing cap to disengage the first latch from the first groove of the connecting strip, and rotate the safety cap to disengage the second latch from the second groove of the connecting strip, allowing the safety cap and sealing cap to be pulled off along the axial direction. This process requires minimal effort, making it easy for even weak or powerless patients to operate. Furthermore, the design requiring the sealing cap and safety cap to be rotated to specific positions before opening reduces the probability of children accidentally opening the bottle and helps prevent accidental ingestion.

[0004] In the aforementioned application, the cooperation between the safety cap and the sealing cap assembly makes it difficult to solve the technical problem of securely locking the bottle body when the safety cap is on the bottle body, resulting in cumbersome operation steps and difficulty in quickly opening the cap in emergency situations. Therefore, we propose a child-safe locking medicine bottle cap. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this utility model provide a child-safe lock medicine bottle cap, which solves the problem of not being able to lock the medicine bottle in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a child safety lock medicine bottle cap, including a medicine bottle, the top of which is provided with a cap, and the inside of the cap is provided with a locking device.

[0007] The locking device includes a push button that is slidably connected to the top of the bottle cap. A push rod is hinged to the circumferential surface of the push button. A fixing plate is hinged to one end of the push rod. A locking seat is fixedly connected to the side of the fixing plate. A pressure spring is fixedly connected to the side of the locking seat. A reinforcing pad is fixedly connected to the end of the pressure spring away from the locking seat. An annular groove A is formed on the circumferential surface of the medicine bottle. A limit groove is formed inside the bottle cap. A limit rod is fixedly connected to the side of the push button.

[0008] For example, in at least one embodiment of the present invention, a child safety lock medicine bottle cap is provided, which further includes: a return spring fixedly connected to the side of the limiting rod, and the end of the return spring away from the limiting rod is fixedly connected to the inner side of the bottle cap. Its function is that after the button is pressed and released, the limiting rod can be automatically reset to the initial position by the elastic force of the return spring, so as to ensure the stability and reliability of the locking device.

[0009] The side section of the locking seat is concave. The inner side of the annular groove A is slidably connected to the end of the locking seat away from the pressure spring. Its function is that when locking the bottle cap, the locking seat can slide along the inner side of the annular groove A, and through the elastic force of the pressure spring, the locking seat is tightly attached to the inner side of the annular groove A, thereby increasing the stability of the locking.

[0010] On the displacement trajectory of the side of the limiting rod and the inner side of the limiting groove, there are two limiting rods, limiting grooves and return springs, which are symmetrical about each other along the central axis of the bottle cap. Their function is to further improve the stability and reliability of the locking device.

[0011] The circumferential surface of the locking seat penetrates and slides through the inner wall of the bottle cap. There are two of the annular groove A, the pressure spring and the locking seat, which can further improve the locking effect and ensure the safety and stability of the medicine bottle.

[0012] According to another aspect, at least one embodiment of this utility model also provides a child-safe lock medicine bottle cap, including a rotating locking device provided at the bottom of the button. The rotating locking device includes a connecting rod, one end of which is fixedly connected to a hinge block. A pull rod is hinged to the bottom of the hinge block, and a sliding plate is hinged to one end of the pull rod. An annular groove B is formed on the inner wall of the medicine bottle, and a through groove is formed on the inner wall of the annular groove B. Its function is that when the button is pressed, the locking device is opened, but when the rotating locking device is triggered, it can only be rotated 90 degrees to open the bottle cap.

[0013] For example, in at least one embodiment of the present invention, a child safety lock medicine bottle cap is provided, which further includes: a displacement top post fixedly connected to the side of the sliding plate, and a displacement limiting plate fixedly connected to the inner wall of the annular groove B. The function of the displacement limiting plate is to increase the efficiency of the work and the degree of locking, thereby further enhancing the safety and stability of the child safety lock medicine bottle cap. The displacement limiting plate limits the rotation distance.

[0014] The side of the displacement top column is provided with an arc surface. The inner wall of the annular groove B is slidably connected to the side of the displacement top column. The axis of the through groove is perpendicular to the axis of the annular groove B. The side of the displacement top column is slidably connected to the inner wall of the through groove. Its function is to reduce friction and resistance, so that it can only open the medicine bottle when it reaches the designated position.

[0015] The side of the displacement limiting plate is located on the displacement trajectory of the side of the displacement top column. There are two of the sliding plate, displacement limiting plate and displacement top column, which can further improve the safety and stability of the rotation locking device.

[0016] The circumferential surface of the connecting rod penetrates and slides through the interior of the bottle cap, and the side of the sliding plate penetrates and slides through the interior of the bottle cap. Its function is to ensure the stability and reliability of the rotating locking device, while making the entire locking process smoother and easier to operate.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] 1. In this utility model, the cooperation between components such as the pressure button, push rod, and fixing plate in the locking device effectively prevents children from accidentally opening the medicine bottle, thereby improving the safety of the medicine bottle. Furthermore, it enhances the locking effect, ensuring that only adults can open the cap using the correct method. This innovative child-safe medicine bottle cap not only boasts a simple structure and convenient operation, but also significantly improves the safety of medicine bottle use, preventing children from accidentally ingesting medications. It possesses extremely high practical value and social significance.

[0019] 2. In this invention, the locking effect and safety of the child-safe medicine bottle cap are further improved through the cooperation of components such as the connecting rod, hinge block, and pull rod in the rotating locking device. When an adult needs to open the bottle cap, they need to press the button to unlock the locking device and simultaneously rotate the bottle cap. At this time, the rotating locking device is triggered, and the bottle cap can only be fully opened after rotating to a specific angle (such as 90 degrees). This design not only increases the number of steps to open the bottle cap, but also further prevents the possibility of children accidentally opening the medicine bottle through the restriction of the rotating locking device. At the same time, the various components in the rotating locking device cooperate smoothly with each other, allowing adults to easily open the bottle cap with correct operation, without causing inconvenience in use.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, it illustrates a child safety lock medicine bottle cap according to an embodiment of the present invention, including a medicine bottle 1, a cap 2 on the top of the medicine bottle 1, and a locking device 3 inside the cap 2.

[0034] The locking device 3 includes a button 301, which is slidably connected to the top of the bottle cap 2. A push rod 302 is hinged to the circumferential surface of the button 301. A fixing plate 303 is hinged to one end of the push rod 302. A locking seat 304 is fixedly connected to the side of the fixing plate 303. A pressure spring 305 is fixedly connected to the side of the locking seat 304. A reinforcing pad 306 is fixedly connected to the end of the pressure spring 305 away from the locking seat 304. An annular groove A307 is opened on the circumferential surface of the medicine bottle 1. A limiting groove 308 is opened inside the bottle cap 2. A limiting rod 309 is fixedly connected to the side of the button 301.

[0035] In some examples, a return spring 4 is fixedly connected to the side of the limiting rod 309. The end of the return spring 4 away from the limiting rod 309 is fixedly connected to the inside of the bottle cap 2. Its function is to allow the limiting rod 309 to automatically return to the initial position through the elastic force of the return spring 4 after the button 301 is pressed and released, so as to ensure the stability and reliability of the locking device 3.

[0036] The side section of the locking seat 304 is set to be concave. The inner side of the annular groove A307 is slidably connected to the end of the locking seat 304 away from the pressure spring 305. Its function is that when locking the bottle cap 2, the locking seat 304 can slide along the inner side of the annular groove A307, and through the elastic force of the pressure spring 305, the locking seat 304 is tightly attached to the inner side of the annular groove A307, thereby increasing the stability of the locking.

[0037] On the displacement trajectory of the side of the limiting rod 309 and the inner side of the limiting groove 308, there are two limiting rods 309, two limiting grooves 308 and two return springs 4, which are symmetrical about each other along the central axis of the bottle cap 2. Their function is to further improve the stability and reliability of the locking device 3.

[0038] The circumferential surface of the locking seat 304 penetrates and slides through the inner wall of the bottle cap 2. There are two annular grooves A307, pressure springs 305 and locking seats 304, which can further improve the locking effect and ensure the safety and stability of the medicine bottle.

[0039] For example, such as Figures 1-5 As shown, when it is necessary to open bottle cap 2, the button 301 must first be pressed. The push rod 302, hinged to the circumferential surface of the button 301, will push the fixing plate 303. The fixing plate 303 will drive the locking seat 304 to move, and the locking seat 304 will compress the pressure spring 305, causing the locking seat 304 to disengage from the annular groove A307. At this time, the limiting rod 309 slides in the limiting groove 308, and at the same time, the return spring 4 is compressed, and bottle cap 2 can be opened. When closing bottle cap 2, the bottle cap 2 is placed on the medicine bottle 1 and pressed down. The locking seat 304 will slide along the inner side of the annular groove A307. When the locking seat 304 slides to the designated position of the annular groove A307, the pressure spring 305 will push the locking seat 304 to press tightly against the inner side of the annular groove A307, completing the locking. At the same time, the limiting rod 309 will automatically reset the button 301 under the elastic force of the return spring 4.

[0040] like Figures 1-5 As shown, this invention illustrates a child-safe lock medicine bottle cap in another embodiment of the present invention. It is largely the same as the technical solution described above, so only the differences are emphasized. A rotating locking device 5 is provided at the bottom of the pressure button 301. The rotating locking device 5 includes a connecting rod 501, one end of which is fixedly connected to a hinge block 502. A pull rod 503 is hinged to the bottom of the hinge block 502, and a sliding plate 504 is hinged to one end of the pull rod 503. An annular groove B505 is formed on the inner wall of the medicine bottle 1, and a through groove 506 is formed on the inner wall of the annular groove B505. Its function is that when the pressure button 301 is pressed, the locking device 3 opens; however, when the rotating locking device 5 is triggered, it must be rotated 90 degrees to open the bottle cap 2.

[0041] In some examples, the sliding plate 504 is also fixedly connected to a displacement top post 6 on its side, and a displacement limiting plate 7 is fixedly connected to the inner wall of the annular groove B505. The function of the displacement limiting plate 7 is to increase the efficiency of the work and the degree of locking, and further enhance the safety and stability of the child safety lock medicine bottle cap. The displacement limiting plate 7 limits the rotation distance.

[0042] The side of the displacement top column 6 is provided with an arc surface. The inner wall of the annular groove B505 is slidably connected to the side of the displacement top column 6. The axis of the through groove 506 is perpendicular to the axis of the annular groove B505. The side of the displacement top column 6 is slidably connected to the inner wall of the through groove 506. Its function is to reduce friction and resistance, so that it can reach the designated position before the medicine bottle 1 can be opened.

[0043] The side of the displacement limiting plate 7 is located on the displacement trajectory of the side of the displacement top column 6. There are two sliding plates 504, displacement limiting plates 7 and displacement top columns 6. Their function is to further improve the safety and stability of the rotation locking device 5.

[0044] The circumferential surface of the connecting rod 501 penetrates and slides through the interior of the bottle cap 2, and the side of the sliding plate 504 penetrates and slides through the interior of the bottle cap 2. Its function is to ensure the stability and reliability of the rotating locking device 5, and at the same time make the entire locking process smoother and easier to operate.

[0045] For example, such as Figures 1-5 As shown, simultaneously, the rotating locking device 5 is triggered, and the connecting rod 501 moves as the pressure button 301 is pressed. This moves the pull rod 503 via the hinge block 502, thereby pushing the sliding plate 504 to slide within the annular groove B505. During this process, the displacement pin 6 slides along the inner wall of the annular groove B505. Since the axis of the through groove 506 is perpendicular to the axis of the annular groove B505, the displacement pin 6 can only slide along the inner wall of the annular groove B505. When the displacement pin 6 slides to the side of the displacement limiting plate 7, it will be restricted by the displacement limiting plate 7. At this time, the bottle cap 2 has rotated ninety degrees. Pulling up the bottle cap 2 allows the displacement pin 6 to slide along the inner wall of the through groove 506, thus opening the bottle cap 2. To close the bottle cap 2, place the bottle cap 2 on the medicine bottle 1 and press down on the pressure button 301. Rotate and release to open.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
