Description
Technical Field
The application relates to the field of medical containers, in particular to an eye drop bottle.
Background
At present, the common eyedrop bottle in the market extrudes liquid medicine by compressing and deforming the bottle body through extruding the bottle body, and directly discharges the eyedrop bottle to drop into human eyes. After hands are loosened, liquid is discharged out of the bottle to generate negative pressure, so that outside air is sucked into the bottle, outside bacteria enter the bottle along with the air to pollute liquid medicine, and liquid medicine is invalid or even harmful to human eyes. The current method for preventing the liquid medicine from losing efficacy is to add a preservative, and the long-term use of the eye liquid medicine containing the preservative can cause damage to eyes.
Meanwhile, the amount of the eye drop bottle dripped each time is not fixed, the amount of the liquid medicine discharged is different along with different hand squeezing force of users, waste can be caused when the liquid medicine is discharged too much, and the eye protection effect cannot be realized when the liquid medicine is discharged too little.
The prior art (US 7249693B2 and CN104058181 a) discloses a liquid dispenser, which is provided with a check valve at both of a liquid medicine suction part and a liquid medicine discharge part, the suction part and the liquid medicine discharge part are provided with a through pipe, which is a storage bin for liquid medicine, so that: when the medicine bottle is pressed, the suction part is closed, the discharge part is opened, and the medicine liquid in the through pipe is discharged; when the medicine bottle is not pressed, the suction part is opened, the discharge part is closed, and due to the negative pressure of the through pipe, the medicine liquid is sucked into the suction part and stored in the through pipe for discharging the medicine liquid when the medicine bottle is pressed next time. Through this kind of mode, the control liquid medicine volume of discharging at every turn is the capacity that the siphunculus can be stored to realize quantitative exhaust effect, the check valve of discharge portion has effectively blocked the entering of air simultaneously. However, the operation mode is axial pressing, which is not suitable for the posture of lateral pressing commonly used by people and is inconvenient for single person operation.
With respect to the related art in the above, the inventors thought that an eyedrop bottle should be designed to be contamination-proof, quantitative, and laterally-pressed.

The embodiment of the application has the advantages that: the upper portion of the medicine bottle is provided with the vent hole 222, the medicine bottle comprises a double-layer medicine liquid container outer layer 221 and a double-layer medicine liquid container inner container 223, the double-layer medicine liquid container outer layer 221 is made of hard materials, the double-layer medicine liquid container inner container 223 is made of elastic materials, liquid inside the double-layer medicine liquid container in the using process is continuously reduced, and the pressure inside the bottle is reduced accordingly. The vent 222 connects the double-layered medical solution container inner container 223 with the atmosphere, and the external atmosphere applies pressure to the surface of the double-layered medical solution container inner container 223, so that when the pressure in the bottle becomes small, the volume of the double-layered medical solution container inner container 223 is compressed, and the pressure is consistent with the atmospheric pressure. The phenomenon that liquid medicine can not be discharged or even flows back after the pressure in the bottle is reduced is prevented.
The embodiment of the application has the advantages that: set up a check valve structure in the discharge portion, open when pressing and go out the liquid hole, close when relaxing and go out the liquid hole, can prevent that external air from getting into eye drop bottle and polluting the liquid medicine to can prevent to expose the contaminated liquid medicine backward flow of external world and pollute surplus liquid medicine, consequently need not to add antiseptic in the liquid medicine, protect the healthy of people's eye when having practiced thrift the resource.
The shell is divided into two parts, namely the upper part and the lower part of the shell, and the two parts are connected through a buckle.
In the embodiment of the present application, the spherical plug 21 is a steel ball, and may also be a copper ball, a glass ball, a rubber ball, or the like.
In this application embodiment, two total press device set up respectively in body both sides, and the structure is more stable. Only one pressing device can be arranged on one side, so that the number of parts is reduced, and the cost is saved.
The present invention and its embodiments have been described above in an illustrative manner, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, the technical scheme and the embodiments similar to the technical scheme are not creatively designed without departing from the spirit of the invention, and the invention shall fall into the protection scope of the invention.
