Description

Technical Field

[0001] The invention belongs to the technical field of desiccant bottles, and more specifically, relates to a bottle cap type self-closing desiccant bottle. Background Art

[0002] Desiccant medicine bottles are commonly used packaging for tablet-type solid medicines. There are two main forms of desiccant delivery: bagged and built-in bottle caps. In the existing technology, packaging usually adopts the method of built-in desiccant in bottle caps. This method utilizes the space on the top of the tablet medicine bottle cap to seal the desiccant inside the cap to achieve the purpose of moisture-proofing. Compared with bagged desiccant, this method saves internal space, reduces direct contact between the medicine and the desiccant, and to a certain extent can also prevent patients or children from accidentally ingesting the desiccant. However, it has at least the following defects: 1. The shelf life of solid medicines is usually long, and the validity period of desiccant is usually shorter than the shelf life of the medicine, and the user cannot know whether the desiccant in the bottle has exceeded the validity period. It is easy for the desiccant to expire without the user knowing, resulting in moisture in the long-term storage of the medicine, affecting the effect of the medicine. 2. It is inconvenient for the user to take out the expired desiccant, and the medicine bottle cannot play the function of moisture-proof and drying after the desiccant expires, and the desiccant medicine bottle cannot be reused. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a bottle cap type self-closing desiccant bottle, which can observe the usage of the desiccant through the light-transmitting plates to remind the user to replace the new desiccant; at the same time, it can repeatedly replace a new batch of desiccant, so that the medicine bottle can maintain its moisture-proof function for a long time and can be recycled.

It should be noted that in this embodiment, Fig.10 As shown, the drying strip 5 includes a paper sleeve and silica gel particles. A plurality of silica gel particles are arranged in the closed paper sleeve. The silica gel particles are conventional desiccants that gradually change color as the degree of moisture absorption increases. The paper sleeve is translucent, and the color of the silica gel particles can be observed. Since the silica gel particles are filled in the paper sleeve, and the paper sleeve has a certain elasticity, after the two ends are hooped into a ring, the drying strip 5 naturally has a tendency to expand outward into a strip.

[0019] The bottle cap 1 is provided with an internal thread 11, and the upper opening of the bottle body 2 is provided with an external thread 21, and the internal thread 11 matches the external thread 21 to make the bottle cap 1 and the bottle body 2 threadedly connected. The bottle body 2 contains solid medicine.

[0020] The drying component 3 includes a drying bin 31, a limiting boss 32, a bottom plate 34 and a light-transmitting plate 36. The drying bin 31 is arranged on the lower side of the bottle cap 1, and the drying bin 31 is a hollow structure. Preferably, in the present embodiment, the bottom surface of the drying bin 31 is flush with the lower side of the bottle cap 1. The limiting boss 32 is arranged at the bottom of the drying bin 31, and the outer diameter of the lower end of the limiting boss 32 is larger than the outer diameter of the upper end. A through annular groove is provided at the bottom of the drying bin 31, and the annular groove is located on the outer side of the bottom of the limiting boss 32. The bottom plate 34 is arranged on the annular groove, and the drying bin 31 and the limiting boss 32 are fixedly connected by the bottom plate 34.

[0021] like Figure 7As shown, a trapezoidal notch is provided on the bottom plate 34, and a lower cover slot is provided on the trapezoidal notch. A lower cover buckle is fixedly provided on the edge of the lower cover 37, and the lower cover slot matches the position of the lower cover buckle, so that the bottom plate 34 and the lower cover 37 are mutually engaged. The buckle and the slot are both conventional technical means, and their specific structure and working principle are not described here. When it is necessary to take out the drying strips 5 in the drying tank 33, the lower cover 37 is opened and the drying strips 5 are respectively taken out therefrom.

[0022] The bottom plate 34 is provided with air holes 35, and a lower cover 37 is detachably connected to the bottom plate 34. The outer peripheral side of the limiting boss 32 cooperates with the inner wall of the drying chamber 31 to form a drying groove 33. The drying strip 5 is located between the drying grooves 33, and the light-transmitting plate 36 is arranged on the upper side of the bottle cap 1 and is located directly above the bottom plate 34. The light-transmitting plate 36 is made of a transparent material to observe the color change of the drying strip 5.

[0023] Preferably, in the present embodiment, the drying component 3 further includes a comparison test paper. The comparison test paper is arranged on the upper side of the bottom plate 34 (not shown in the figure), and is located between the drying strip 5 and the bottom plate 34. An opening is provided on the comparison test paper, and the shape and position of the opening match the air vent 35. The surface of the comparison test paper includes an indicator color of the change process from effective to ineffective of the color developing desiccant. Among them, the comparison test paper is pasted on the upper side of the bottom plate 34, and the color change of the silica gel particles from effective to ineffective is respectively shown from the head end to the tail end of the comparison test paper, and the head end is marked with the word "effective" and the tail end is marked with the word "ineffective".

[0024] The material changing assembly 4 is nested between the light-transmitting plates 36. The material changing assembly 4 includes a material preparation bin 41, an upper cover 42, an end cover 43, a button 44, a pressure column 45, a reset spring 46, a connecting rod 47, a material discharge baffle 48 and a connecting plate 49. The material preparation bin 41 includes a first support plate 411 and a second support plate 412, which are used to place the drying strips 5. The outer diameter of the second support plate 412 is larger than the outer diameter of the first support plate 411, and is fixedly connected by a connecting plate 49. The outer wall of the second support plate 412 is fixedly connected to the light-transmitting plate 36, and the end cover 43 is fixedly arranged on the inner side of the first support plate 411. The button 44 and the end cover 43 are connected to each other in an up-and-down sliding manner, and the lower end of the button 44 is fixedly connected to the upper end of the pressure column 45. The lower end of the pressure column 45 is connected to one end of the reset spring 46, and the other end of the reset spring 46 is connected to the upper side of the limiting boss 32. A connecting rod 47 is fixedly connected to the outer side of the pressure column 45, and the connecting rod 47 is connected to the material discharge baffle 48. The material discharge baffle 48 is an annular structure and is located at the lower side of the material preparation bin 41 to block the drying strips 5. The upper cover 42 is detachably connected to the upper side of the material preparation bin 41 to seal the material preparation bin 41.

[0025] The side of the material discharge baffle 48 receiving the drying strip 5 is an inclined surface, and the inclined surface is downward toward the second support plate 412 to guide the drying strip 5 to fall. When the drying strip 5 is located in the material preparation bin 41, it is in a compressed state, and its surface abuts against the second support plate 412, and has a tendency to expand outward.

[0026] The upper cover 42 is provided with a notch that matches the shape of the connecting plate 49. An upper cover buckle (not shown) is fixedly provided on the lower side of the upper cover 42, and an upper cover slot is provided on the side wall of the first support plate 411. The upper cover slot matches the upper cover buckle position so that the upper cover 42 and the first support plate 411 are mutually engaged. The buckle and the slot are both conventional technical means, and their specific structure and working principle are not described here. When a new drying strip 5 needs to be loaded, the upper cover 42 is opened, and the new drying strip 5 is hooped into a ring shape and then inserted into the preparation bin 41.

[0027] Working principle: A plurality of drying strips 5 are installed in the preparation bin 41. The plurality of drying strips 5 are stacked on each other. The upper cover 42 is opened, and a new drying strip 5 is hooped into a ring shape and inserted into the preparation bin 41. At this time, the drying strip 5 is in a compressed state and has a tendency to expand outward into a strip shape. The drying strip 5 at the bottom of the drying slot 33 absorbs moisture in the medicine bottle through the air holes 35. The user can directly observe the color change of the drying strip 5 through the light-transmitting plate 36 and compare it with the comparison test paper to directly know the use status of the drying strip 5, so as to remind the user to replace the new drying strip 5 and prevent the drying strip 5 from failing prematurely. The drying strips 5 in the drying slots 33 are in an unfolded state; when the drying strips 5 in the drying slots 33 need to be taken out, the lower cover 37 is opened and the drying strips 5 are taken out respectively. Meanwhile, the lower cover 37 needs to be opened to replace the drying strips 5, so as to prevent children or users from accidentally ingesting the desiccant; it should be noted that the old and invalid drying strips 5 are cleaned out in time so that the drying slots 33 are filled with new drying strips 5, which is beneficial to the moisture-proof effect in the bottle.

[0028] When it is necessary to add a new drying strip 5, the button 44 is pressed downward, the pressure column 45 moves downward, and the material discharge baffle 48 is driven to move downward through the connecting rod 47. The drying strip 5 at the bottom of the preparation bin 41 is gradually expanded outward by the action of gravity and its own elasticity, and moves downward along the inclined surface of the material discharge baffle 48. The inclined surface of the material discharge baffle 48 guides the drying strip 5 downward. When the pressure column 45 moves downward to the limit position, the gap between the material discharge baffle 48 and the second support plate 412 allows the drying strip 5 at the bottom to fall out. The drying strip 5 falls into the drying groove 33 along the outer surface of the limiting boss 32, and is superimposed on the old drying strip 5 to continue to maintain the moisture-proof function of the medicine bottle. The return spring 46 causes the pressure column 45 and the button 44 to return upward, and the discharge baffle 48 moves toward the lower opening of the preparation bin 41 to prevent the subsequent drying strips 5 from continuing to fall; New drying strips 5 can be added by opening the upper cover 42, and a new batch of desiccant can be repeatedly replaced, so that the medicine bottle can maintain the moisture-proof function for a long time and the medicine bottle can be recycled.

[0029] Specific embodiment 2: Please refer to Figure 11-Figure 12 A bottle cap type self-closing desiccant bottle is provided, and the same points as the specific embodiment 1 are not repeated here, and the difference is that: the discharge baffle 48 is also provided with a protection plate 481. The protection plate 481 is fixedly arranged on the side of the discharge baffle 48 close to the first support plate 411, and the side of the protection plate 481 abuts against the side of the first support plate 411. When the discharge baffle 48 moves downward, the gap distance between the discharge baffle 48 and the second support plate 412 becomes larger, and the drying strip 5 falls from the gap.

[0030] By providing the protection plate 481, the material discharge baffle 48 blocks the inner side of the material preparation bin 31 when moving downward, preventing the drying strip 5 from extending toward the first support plate 411, so that it can fall from the gap faster and more effectively. Preferably, an extension plate is provided on the lower side of the second support plate 412. In this embodiment, when the pressure column 45 is in the initial position, the upper side of the inclined edge of the material discharge baffle 48 abuts against the lower side of the extension plate to improve the sealing of the material preparation bin 41, which can improve the control effect of replacing the drying strip 5 and prevent the drying strip 5 from becoming ineffective too quickly or too slowly due to long-term use.
