Description

Liquid medicine dispenser

The present invention relates to a pharmaceutical liquid dispenser, and more particularly, to a pharmaceutical liquid dispenser used as an eye drop container capable of stably discharging a predetermined amount of a liquid dropwise during administration of eye drops and preventing the penetration of foreign substances and bacteria.

In general, a dispenser is a device that discharges a certain amount of gas, liquid, or other contents filled in an airtight container by pressure, and is applied to various airtight containers for storing cosmetics, perfumes, medicines, or food. is becoming

On the other hand, as life becomes more sophisticated and industry develops, pollution of the environment becomes serious, and people's fatigue is increasing. In particular, the health of the eyes, which is exposed to various displays such as smartphones and monitors, is easy to infringe, and the use of eye drops continues to increase.

These eye drops include a liquid type or a gel type, and the liquid type eye drops are stored in an eye drop container.

Existing eye drops do not have an indicator for accurate administration, so they simply have to be injected into the eye while tilting or moving the eye drop container depending on the patient's senses. During this process, there were various inconveniences, such as dropping the eye drops from a place other than the eye or hurting the eye with the eye drop container.

1 is a view schematically showing a conventional eye drop container.

Referring to Figure 1, the eye drop container (1) is provided with a cylindrical storage body (2) made of a synthetic resin material, the injection unit (4) formed with an outlet (5) on the upper portion of the storage body (2) is vertically In a standing state, communication is formed integrally.

The stopper 9 is screwed to the lower portion of the injection unit 4 or the reservoir 2 to cover the injection unit 4 .

Therefore, if you want to instill eye drops, after separating the stopper 9 from the injection unit 4, the eye drop container 1 is placed above the eye in an inverted state, and the eye drop is dropped into the eye drop by drop.

An example of such a technique is disclosed in Documents 1 to 3 and the like.

For example, in Patent Document 1 below, a main body with an open upper portion and protecting a liquid chemical solution, a discharge passage connected to the upper portion of the main body, and a discharge passage for discharging the chemical liquid, and a step formed so that the diameter of the inner diameter of the discharge passage is narrowed and a discharge member having a discharge unit and a check valve formed on the discharge passageway, an opening/closing member provided in the discharge unit to discharge the chemical solution in a droplet shape, and a cover member covering the discharge member. have.

In addition, the following Patent Document 2 includes an eye drop container body having an empty interior and an outlet formed at the upper end, and an aiming mechanism charged and fixed inside the eye drop container body, wherein the aiming mechanism is an external ball, and charged in the external ball an inner ball, which is coupled to the outer ball and includes a fixing frame for fixing the outer ball to the inner surface of the eye drop container body, wherein the outer ball is filled with a liquid around the inner ball, and the inner ball is partially filled with a filler It is disclosed for an ophthalmic case with

On the other hand, the following Patent Document 3 includes a body portion that accommodates eye drops and an outlet is formed at the end, and a lid coupled to the main body portion, the main body portion is located around the outlet, and protrudes outward than the outlet It is disclosed for an ophthalmic container in which an eyelid lifter is formed to raise the eyelids of a subject when administering eye drops.
