Description

Technical Field

[0001] The utility model relates to the technical field of eye drop bottles, in particular to a solid-liquid separation type eye drop bottle. Background Art

[0002] Some special drugs (such as rifampicin) are easy to deteriorate after contact with water, which is not conducive to long-term storage, and solid drugs are not suitable for eye medication. Eye drops of this nature are usually packaged in a solid-liquid separation manner.

[0003] The solid-liquid separation packaging eye drop device currently on the market has tablets and buffer solution packaged separately. When patients use it, they must first open the tablet package (such as aluminum-plastic blister packaging) and unscrew the buffer solution bottle cap, put the tablet into the buffer solution, tighten the bottle cap, and shake it until the tablet is dissolved before use. This process is cumbersome to operate, and it is difficult to avoid the patient's hands touching the tablets, and there is a risk of bacteria and dust contaminating the eye drops.

[0004] The existing patent document (application number: KR1020200053151) discloses a solid-liquid separation container cover. Although its main function is to separate and store the solid content from the liquid content stored in the container body, the solid-liquid separation container cover is applied to containers such as oral bottles, rather than eye drop bottles. In addition, the solid-liquid separation container cover is composed of three parts: an outer cover, an inner cover and a middle cover, and the specific structures of these three parts are relatively complex. Finally, refer to paragraph

[0044] of the existing patent document specification: When the outer cover 10 is opened in the container body (B), the middle cover 30 is also removed together with the outer cover 10 by engaging the outward engagement protrusion 15 and the inward engagement protrusion 35. In other words, the sealing structure between the middle cover 30 and the inner cover 20 must be released by opening the outer cover 10, and the pills are immersed in the beverage, which may cause the pills or beverages to be contaminated by bacteria in the external air, posing a safety and sanitation hazard.

[0084] Therefore, the solid-liquid separation eye drop bottle of the utility model can realize an integrated solid-liquid separation packaging form, and the solid medicine 6 can be put into the buffer solvent without pollution by screwing the anti-theft cover 2, which is more convenient to use and the eye drops are safer and more reliable.

[0085] The various states of the solid-liquid separation eye drop bottle are described in detail:

[0086] When not enabled (such as Figure 5 As shown): the bottom cover 4, the inner plug 3, the anti-theft cover 2, and the protective cap 5 together define a closed space for storing solid medicine 6; at the same time, the bottom cover 4, the inner plug 3, and the medicine bottle 1 together define a closed space for storing buffer solvent.

[0087] When enabled (such as Figure 4 and Figure 6As shown in the figure, the anti-theft cover is rotated in the preset tightening direction (i.e. clockwise), the anti-theft cover 2 is further tightened relative to the liquid medicine bottle 1, the anti-theft cover moves downward, and the inner column 23 pushes the bottom cover 4 downward under the drive of the cover body 21 until the bottom cover 4 is downwardly separated from the inner plug 3, and the bottom cover 4 and the solid medicine 6 fall into the buffer solvent together, so that the solid medicine 6 falls into the buffer solvent. Subsequently, the entire solid-liquid separation type eye drop bottle is continuously shaken to completely dissolve the solid medicine 6 in the buffer solvent, and finally the eye drops are prepared.

[0088] After activation: the medicine bottle 1, the inner plug 3, the anti-theft cover 2, and the protective cap 5 together define a closed space for storing eye drops.

[0089] When using (such as Figure 7 and Figure 8 As shown): remove the protective cap 5, invert the solid-liquid separation type eye drop bottle and align the drip head 22 with the eye, squeeze the liquid medicine bottle, the eye drops drip out, and the medication is completed.

[0090] The solid-liquid separation eye drop bottle has good sealing properties, namely:

[0093] The third sealing position: the inner plug has an interference fit with the medicine bottle, which prevents the buffer solvent from leaking when not activated and prevents the eye drops from leaking after activation.

[0094] Fourth sealing position: the inner plug is interference-fitted with the bottom cover 4 to prevent leakage of the buffer solvent when not in use.

[0095] Furthermore, in order to enable the protective cap 5 to have the function of blocking the dripping hole 222, the dripping head 22 includes a tubular liquid outlet 223 connected to the inner column 23 and a dripping end 224 provided at the top of the tubular liquid outlet 223, the tubular liquid outlet 223 forms the liquid collecting cavity 221, and the dripping hole 222 is formed in the dripping end 224; the protective cap 5 includes a cap part 51 and a hole blocking part 52 provided at the top of the cap part 51 and protruding downward, the cap part 51 is threadedly sleeved on the tubular liquid outlet 223, and the hole blocking part 52 blocks the dripping hole 222 when the protective cap 5 is tightened to the preset limit position. The hole blocking part 52 and the dripping hole 222 are interference fit to achieve the sealing function.

[0096] Furthermore, the outer peripheral wall of the protective cap 5 has anti-slip grooves, which is convenient for rotating the protective cap 5. The protective cap 5 and the drip head 22 are threadedly connected, which is convenient for the patient to control the opening and closing of the drip hole 222 by unscrewing or tightening.

[0097] As a specific embodiment of the anti-theft cover 2: the outer peripheral wall of the tubular liquid outlet 223 of the drip head 22 has a small thread, so that it can be threadedly connected with the protective cap 5.

[0098] Furthermore, in order to simplify the structure of the bottom cover 4, the bottom cover 4 includes a cover plate portion 42, on which is provided an inner ring portion 43 and an outer ring portion 44 concentrically arranged with the inner ring portion 43, the inner cavity of the inner ring portion 43 constitutes the medicine storage chamber 41, and the annular gap between the outer ring portion 44 and the inner ring portion 43 forms a sealing groove portion 45, and a sealing clamping relationship is formed between the sealing groove portion 45 and the bottom port of the inner plug 3.

[0099] Furthermore, the inner peripheral wall of the outer ring portion 44 has an annular sealing protrusion to prevent the interference position from creeping and loosening. The outer peripheral wall of the inner ring portion 43 and the inner peripheral wall of the outer ring portion 44 are both interference-fitted with the inner plug 3, and the sealing is more reliable.

[0100] Furthermore, if Fig. 9 , Fig.18 , Fig.19 As shown, in order to facilitate patients to identify that the product has been activated, the outer peripheral wall of the bottle mouth 12 close to the bottle body 11 is provided with a bottleneck protrusion 14, and the bottleneck protrusion 14 is gradually expanded from top to bottom; the anti-theft cover 2 also includes an anti-theft ring 24 connected to the cover body 21, and the anti-theft ring 24 is broken by the bottleneck protrusion 14 when the user rotates the anti-theft cover 2 in a preset tightening direction. When in use, when the anti-theft cover is rotated clockwise, the cover body 21 of the anti-theft cover moves downward to push the anti-theft ring 24. Since the inner diameter of the anti-theft ring 24 is smaller than the maximum outer diameter of the bottleneck protrusion 14, during the downward movement of the cover body 21, the anti-theft ring is gradually expanded by the bottleneck protrusion 14 until the anti-theft ring expands and breaks. Fig. 9 The A region in the figure is the cracking position of the anti-theft ring. Specifically, the bottle neck protrusion 14 has a wedge-shaped surface, and the wedge-shaped surface and the anti-theft ring 24 form a sliding abutment fit.

[0101] Furthermore, the anti-theft ring 24 includes an arc-shaped strip 241 with a disconnection opening, and the disconnection openings of the arc-shaped strip 241 are connected via a breakable connector 242 .

[0102] Furthermore, the liquid medicine bottle is preferably made of LDPE (low-density polyethylene), so that the bottle body 11 has good flexibility, so that the patient can squeeze and administer the medicine. Furthermore, the inner wall of the bottle mouth 12 has an annular sealing groove, and the annular sealing groove of the bottle mouth 12 is matched with the annular sealing protrusion of the inner plug 3 to prevent the interference position from creeping and loosening.

[0103] Furthermore, in order to ensure good sealing between the inner plug 3 and other parts, the inner plug 3 includes an inner plug body 32 that is connected from top to bottom, the flow hole 31 is formed in the inner plug body 32, the lower port edge of the inner plug body 32 extends downward to form a snap-on lip 33, the upper port edge of the inner plug body 32 extends radially outward to form a stop flange 34, the snap-on lip 33 is sealed and snap-on with the bottom cover 4, and the stop flange 34 abuts against the opening of the bottle mouth 12. The outer peripheral wall of the inner plug body 32 can be called a large outer circular surface, and the outer peripheral wall of the snap-on lip 33 can be called a small outer circular surface. The large outer circular surface is interference-fitted with the liquid medicine bottle to achieve a sealing function, and the large outer circular surface has an annular sealing protrusion, which is adapted to the annular sealing groove of the bottle mouth 12 (also mentioned above) to prevent the interference position from creeping and loosening. The small outer cylindrical surface is interference fit with the bottom cover 4 to achieve a sealing function; the small outer cylindrical surface has an annular sealing groove, which is adapted to the annular sealing protrusion of the outer ring portion 44 to prevent the interference position from creeping and loosening. The inner hole surface of the flow hole 31 is respectively interference fit with the inner column 23 of the anti-theft cover and the bottom cover 4 to achieve a sealing function.

[0104] Furthermore, in order to prevent the bottom cover 4 from blocking the flow hole 31 of the inner plug 3 when dripping liquid, the density of the bottom cover 4 is smaller than the density of the buffer solvent.

[0105] Furthermore, in order to improve the rigidity of the inner column 23 , the anti-theft cover 2 further includes reinforcing ribs 25 , which are arranged on the inner wall of the drip head 22 and the inner wall of the inner column 23 .

[0106] Furthermore, when the solid medicine 6 is in the form of a pill, in order to prevent the solid medicine 6 from being damaged by collision, the number of the reinforcing ribs 25 is multiple, each reinforcing rib 25 extends up and down, and the lower ends of all the reinforcing ribs 25 are used to jointly restrict the movement range of the solid medicine 6.

[0107] In summary, the solid-liquid separation eye drop bottle of the utility model can realize an integrated solid-liquid separation packaging form, and solid drugs can be put into the buffer solvent without pollution by screwing the anti-theft cover, which is more convenient to use and the eye drops are safer and more reliable. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
