Description

Technical Field

[0001] The utility model relates to the technical field of eye drop bottles, in particular to an eye drop bottle. Background Art

[0002] An eye drop bottle is a small container used to store and use eye drops or eye solutions. It is usually made of transparent plastic or glass and has a slender dropper or dropper hole that allows the liquid to be easily dropped into the eye. The design of the eye drop bottle helps ensure that the liquid is not contaminated during use.

[0003] At present, when instilling the medicine into the eye drop bottles available on the market, if too much force is used, the amount of medicine instilled will increase, and vice versa. Therefore, it is difficult to accurately control the amount of medicine to be instilled during instillation. Utility Model Content

[0004] The purpose of the utility model is to provide an eye drop bottle to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An eye drop bottle comprising

[0007] An inner shell, wherein a liquid outlet pipe is movably installed at the lower part of the inner shell, and an adjustment mechanism is provided between the inner shell and the liquid outlet pipe;

[0008] The outer shell is arranged on the outer side of the inner shell, and the bottom end of the outer shell is provided with a liquid outlet mechanism.

[0009] Preferably, the adjustment mechanism includes a pressure rod, a pressure head and a spring, the pressure rod is movably mounted on the inner middle part of the inner shell, the top end of the pressure rod passes through the inner shell and is fixedly mounted on the pressure head, the bottom end of the pressure rod is fixedly connected to the top end of the liquid outlet pipe, the spring is arranged on the lower surface of the middle part of the inner upper end of the inner shell, and the other end of the spring is fixedly sleeved on the outside of the pressure rod;

[0010] Preferably, the top and bottom ends of the liquid outlet pipe are further provided with an inlet and an outlet, the interior of the liquid outlet pipe is provided with a liquid storage cavity connected to the inlet and the outlet, and the bottom end of the liquid outlet pipe is provided with a sealing member on the outside;

[0011] Preferably, a partition is provided at the upper end of the middle portion of the inner side of the inner shell, the middle portion of the partition is movably connected to the pressure rod, and a rubber sealing ring is provided at the connection between the partition and the pressure rod;

[0012] Preferably, the liquid discharge mechanism includes a drip tube, which is connected to the lower middle portion of the bottom end of the shell, and a diaphragm is provided in an annular shape at the lower inner portion of the shell;

[0013] Preferably, an air chamber is provided on the outer side of the housing close to the diaphragm, and a liquid chamber is provided on the inner side of the housing close to the diaphragm;

[0014] Preferably, the outside of the drip tube is sleeved with a plug.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This eye drop bottle is used in conjunction with an inner shell, a pressure rod, a pressure head, a liquid outlet tube and an inlet and outlet. Since the inlet and outlet at the upper end of the liquid outlet tube are located inside the inner shell, a fixed amount of liquid medicine has been pre-filled in the liquid storage cavity inside the liquid outlet tube. After the liquid outlet tube is lowered, the liquid medicine inside the liquid outlet tube flows out from the inlet and outlet below and enters the liquid chamber below the outer shell. After pressing once, a drop of liquid medicine will be poured into the liquid chamber. The specific amount poured in can be adjusted according to the needs of the user. In this way, when dripping the liquid medicine, the amount of medicine dripped each time can be controlled according to needs.

[0017] 2. This eye drop bottle is used in conjunction with an outer shell, a diaphragm, an air chamber, a liquid chamber and a plug. After a certain amount of liquid medicine is poured into the liquid chamber, the plug on the outside of the dropper is removed, and then the outer shell is pinched to move the dropper to a certain distance outside the upper end of the eyeball, and then the outer shell is squeezed. When the outer shell is squeezed, the gas inside the air chamber is pressurized to control the diaphragm to bulge toward one side of the liquid chamber, and then the liquid medicine inside the liquid chamber is squeezed out of the dropper and dripped onto the eyeball. In this way, the liquid medicine can be dripped conveniently during use, and the amount of liquid medicine dripped will not be affected by the different pressing strengths each time.
