[0002] With the popularization of electronic products, the demand for eye drops has been increasing day by day. The design of eye medicine bottles has also become increasingly diverse, from simple to complex, to meet various needs of modern people.

[0003] The existing design of eye medicine bottles usually includes a storage bottle and a bottle cap. When in use, the storage bottle is inverted, and the liquid medicine is dripped out by squeezing the bottle body. However, during the use of this kind of eye medicine bottle, the amount of dripping liquid may be inaccurate and difficult to control due to different squeezing forces or angles. Utility Model Content

[0004] In order to facilitate the user to squeeze and control the amount of dripping liquid, this application provides an eye medicine bottle that facilitates quantitative dripping of liquid medicine.

[0005] An eye medicine bottle that facilitates quantitative dripping of liquid medicine provided by this application adopts the following technical solutions:

[0006] An eye medicine bottle that facilitates quantitative dripping of liquid medicine includes a storage bottle and a bottle cap. Two fixed tubes are symmetrically arranged along the radial direction of the storage bottle. The two fixed tubes are coaxially arranged, and a deformation tube is integrally formed between the two fixed tubes. When the storage bottle is pressed, the two fixed tubes approach each other and squeeze the deformation tube.

[0007] By adopting the above technical solutions, when dripping the liquid medicine, a force is applied to the bottle body. During this process, the two fixed tubes approach each other and squeeze the deformation tube until it cannot be squeezed anymore. At this time, the liquid medicine drips; when the force is released, the bottle body drives the fixed tubes and the deformation tube to return to their original states. Compared with the eye medicine bottles in the prior art, in this application, through a rigid limiting method, the user can accurately control the amount of dripping liquid and is not easily affected by external factors.

[0008] Preferably, the interiors of the fixed tubes and the deformation tube are hollow and communicate to form a channel, and both ends of the channel penetrate through the storage bottle;

[0009] Pressing parts are provided at both ends of the channel, and the pressing parts are fixedly connected to the side wall of the storage bottle.

[0012] By adopting the above technical solution, the setting of the guide component is mainly used to improve the stability of the pressing operation. On the one hand, it is used to guide the fixed tube, and on the other hand, it can make the bottle body quickly return to its original state, making the dripping amount more accurate.

[0013] Preferably, one end of the telescopic tube extending into the fixed tube is integrally formed with a limited edge, and the open end of the fixed tube is integrally formed with a retaining ring for preventing it from falling off.

[0014] By adopting the above technical solution, the setting of the limiting edge and the retaining ring is mainly used to prevent the telescopic tube from being completely separated from the fixed tube.

[0015] Preferably, the pressing portion is block-shaped, and has a surface with textures for increasing friction.

[0016] By adopting the technical solution, fingers can be prevented from slipping and operation is facilitated.

[0017] Preferably, the bottle cap comprises an inner thorn cover and an outer sealing cover;

[0018] The top of the inner piercing cover is processed with a dripping port, and a puncturing body in an inverted cone shape is integrally formed at the dripping port. The tip of the puncturing body extends to the inside of the inner piercing cover, and the tip of the puncturing body is provided with a liquid passing hole;

[0019] The inner thorn cover is threadedly connected to the storage bottle, and the outer sealing cover is threadedly connected to the inner thorn cover.

[0025] 1. When dripping liquid in the present application, a force is applied to the bottle body. During this process, the two fixed tubes approach each other and squeeze the deformation tube until it cannot be squeezed any further. At this time, the liquid medicine drips; when the force application is released, the bottle body drives the fixed tube and the deformation tube to return to their original states. Compared with the existing eye drops bottles, in the present application, through the hard limit method, the user can accurately control the dripping amount and is not easily affected by external factors;

Detailed Embodiment

[0032] The following will further elaborate on the present application in conjunction with the attached Figures 1-4 drawings.

[0033] The embodiment of the present application discloses an eye drops bottle convenient for quantitative dripping. Referring to Figure 1 , the eye drops bottle includes a storage bottle 1 and a bottle cap. The storage bottle 1 is processed from low-density polyethylene material, which has good flexibility, extensibility and transparency. On the one hand, it is convenient to return to its original state after pressing, and on the other hand, it is convenient for the user to observe the usage situation of the liquid medicine. Scale lines 11 are provided on the bottle body of the storage bottle 1, which, in combination with the transparent bottle body, makes it more convenient for the user to observe the usage situation and the remaining amount of the liquid medicine.

[0034] Referring to Figure 1 andFigure 2 The bottle cap includes an inner puncturing cap 2 and an outer sealing cap 3. The double-layer cap design can greatly ensure the overall sealing performance. A liquid dripping port 21 is processed at the top of the inner puncturing cap 2. A plug 31 adapted to the liquid dripping port 21 is integrally formed on the inner top wall of the outer sealing cap 3 for blocking the liquid dripping port 21. A puncturing body 22 is integrally formed at the liquid dripping port 21. The puncturing body 22 extends towards the inside of the inner puncturing cap 2 away from the liquid dripping port 21, with a gradually decreasing aperture and an inverted conical shape. A liquid passing hole is provided at the tip of the puncturing body 22. A diversion groove (not visible in the figure) is provided around the liquid dripping port 21 to ensure that liquid drops can fall smoothly during use.

[0035] The storage bottle 1, the inner puncturing cap 2 and the outer sealing cap 3 are all connected by threads. The inner puncturing cap 2 is threadedly connected to the storage bottle 1, and the outer sealing cap 3 is threadedly connected to the inner puncturing cap 2. It should be noted that the connection between the inner puncturing cap 2 and the storage bottle 1 is a semi-threaded connection, that is, the puncturing body 22 has not pierced the storage bottle 1, and the liquid medicine in the storage bottle 1 is in a sealed state. The thread directions of the inner puncturing cap 2 and the storage bottle 1 and between the outer sealing cap 3 and the inner puncturing cap 2 are the same. During use, simply screwing the outer sealing cap 3 can cause the puncturing body 22 of the inner puncturing cap 2 to pierce the storage bottle 1, which is convenient and practical.

[0036] Refer to Figure 3 and Figure 4 Inside the storage bottle 1, two fixing tubes 4 are symmetrically arranged along its radial direction. The two fixing tubes 4 are coaxially arranged, and a deformable tube 5 is integrally formed between the two fixing tubes 4. Among them, the fixing tubes 4 are rigid tubes that are not easily deformed or bent under extrusion, while the deformable tube 5 is a soft tube, similar to flexible bellows, spring 73 tubes and other structures, which is easily deformed, that is, compressed, under extrusion. When pressing the storage bottle 1, the two fixing tubes 4 approach each other and squeeze the deformable tube 5 until it cannot be squeezed anymore. The compression amount of the deformable tube 5 is the dripping volume of a drop of liquid medicine. The accurate control of the dripping volume is achieved through this hard-limiting method.

[0037] The interiors of the fixing tubes 4 and the deformable tube 5 are hollow and communicate to form a channel. The two ends of the channel penetrate through the storage bottle 1. Pressing parts 6 are provided at both ends of the channel. The pressing parts 6 are fixedly connected to the side wall of the storage bottle 1, specifically, they can be bonded. The pressing parts 6 are designed in different shapes, such as hemispherical, circular or other special shapes, and the surface has patterns for increasing friction. Users can choose according to their preferences when purchasing. The setting of the pressing parts 6 facilitates users to find the pressing position accurately.

[0038] Refer to Figure 4, a guide assembly 7 is provided in the channel, which is mainly used to improve the stability of the pressing operation. The guide assembly 7 includes a fixed cylinder 71, a telescopic cylinder 72 with one end extending into the fixed cylinder 71 and slidingly matched with the fixed cylinder 71, and a spring 73 located in the fixed cylinder 71; the outer wall of the fixed cylinder 71 fits with the inner wall of the fixed tube 4; the telescopic cylinder 72 is a variable diameter structure, and the outer wall of the part of the rod body of the telescopic cylinder 72 away from the spring 73 also fits with the inner wall of the fixed tube 4 without affecting the compression of the deformation tube 5, and the distance between the step surface (the position of the variable diameter) of the thicker rod body of the telescopic cylinder 72 and the end face of the fixed cylinder 71 is equal to the distance of the compression of the deformation tube 5, that is, the dripping amount of a drop of liquid medicine. In this way, a limit can be formed between the fixed cylinder 71 and the telescopic cylinder 72, and the accuracy can be further ensured; one end of the spring 73 is fixedly connected to the inner bottom wall of the fixed cylinder 71, and the other end is fixedly connected to the end face of the telescopic cylinder 72, and the ends of the fixed cylinder 71 and the telescopic cylinder 72 that are away from each other are respectively fixedly connected to the corresponding pressing part 6.

[0039] When force is applied to the bottle body, the deformation tube 5 is compressed, and at the same time, the spring 73 is also compressed; when the force is released, the bottle body quickly returns to its original shape under the action of the spring 73. This arrangement makes the dripping amount more accurate.

[0040] A limiting edge 74 is integrally formed at one end of the telescopic tube 72 that extends into the fixed tube 71, and a retaining ring 75 for preventing detachment is integrally formed at the open end of the fixed tube 71. When the telescopic tube 72 is extended to the limit, the limiting edge 74 abuts against the retaining ring 75 to prevent the telescopic tube 72 from completely detaching from the fixed tube 71.

[0041] The implementation principle of the embodiment of the present application is as follows: when using for the first time, the outer cover 3 is screwed to make the puncture body 22 on the inner puncture cover 2 puncture the storage bottle 1; when dripping, force is applied to the pressing part 6, during which the two fixed tubes 4 approach each other and squeeze the deformable tube 5 until the squeezing stops, at which time the liquid drops from the dripping port 21 along the guide groove; when the force is released, the bottle body quickly returns to its original state under the action of the spring 73. Compared with the eye drop bottle in the prior art, the structural design in the present application facilitates the user to accurately control the dripping amount.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
