Abstract

(57) [Summary] [Purpose] To provide an eye drop container capable of sufficiently supplying eye drops into the eye. [Structure] A cylinder portion CY is provided on the surface of a container bi containing an eye drop L, a piston chamber pc for accommodating a piston pi is formed in the cylinder portion cy, and the piston pi is elastically pressed outward by a spring S. , The piston chamber pc communicates with the liquid suction pipe ap inserted into the eye drop L, and the liquid spray hole ip penetrates through the cylinder portion cy, and the piston chamber pc is connected between the liquid suction pipe ap and the piston chamber pc. A spray-type eye drop container in which a second check valve rv2 is provided in and a second check valve rv1 is provided on the outlet side of the liquid spray hole ip. [Function] The effect of the eye drop can be sufficiently exerted in the eye drop container in which the eye drop is sprayed from the container and vigorously supplied into the eye.

Description

[Detailed description of the device]

[0001]

[Usage field]

 Eye drop container to spray eye drops.

[0002]

[Prior art]

 Since the conventional eye drop container drips the eye drop, it is not sufficiently supplied to the eye and its effect is not sufficient.

[0003]

[Problems to be solved]

 To provide an eye drop container capable of sufficiently supplying eye drops into the eye.

[0004]

[Technical means and action]

 The effects of the eye drops can be fully exerted in the eye drop container in which the eye drops are sprayed from the container and supplied vigorously into the eye.

[0005]

[First Embodiment] A first embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, a cylinder portion cy is attached to the top surface of the eye drop container bi.

The piston pi is housed in the piston chamber pc of the cylinder portion cy while being elastically pressed outward by the spring S. rv1 is a first check valve attached to the liquid spray hole ip formed in the cylinder portion cy, and rv2 is a second check valve attached to the top of the liquid suction pipe ap.

The operation will be described below. When the piston pi is pushed when the first check valve rv1 is closed and the second check valve rv2 is open, the eye drop L that has filled the piston chamber pc against the spring S is the first check valve rv1. Is pushed open and sprayed from the liquid spray hole ip.

Next, when the piston pi is released, the piston pi returns to its original position by the spring S.

Then, the first check valve rv1 is closed, and the second check valve rv2 is opened by the eye drops L being pushed by the atmospheric pressure communicating from the air hole ah. Thus, the eye drop L penetrates and fills the piston chamber PC.

[0011]

[Explanation of Second Embodiment] Next, a second embodiment shown in FIG. 2 will be explained. In FIG. 2, the liquid discharge pipe Lp is inserted deep into the eye drop L in the eye drop container bi. An air hole ah is formed near the top surface of the container bi.

A cylinder portion cy is attached to the top surface of the container bi, and a piston pi is housed in the piston chamber pc thereof while being elastically pressed outward by a spring S.

Further, the piston chamber pc is provided with an air ejection hole ai and an air suction hole ah. A first check valve rv1 is attached to the air ejection hole ai, and a second check valve rv2 is attached to the air suction hole ah.

Next, the operation will be described. First, when the first check valve rv1 is closed and the second check valve rv2 is opened, when the piston pi is pushed against the spring S, the first check valve rv1 opens and the second check valve rv2. Is closed, and the air in the piston chamber pc is ejected from the air ejection port ai.

When the air is ejected from the air ejection port ai, a negative pressure is generated at the tip of the liquid discharge pipe Lp, and the eye drops L are mixed with the air and sprayed from the liquid discharge pipe Lp.

When the piston pi returns to the original position, the first check valve rv1 is closed, the second check valve rv2 is closed, and the spray of the eye drop L is stopped. Then, the inside of the piston chamber pc becomes close to a vacuum, and the piston chamber pc is filled with air from the air suction hole ah.

[0017]

【effect】

 Since the eye drops are ejected in the form of a spray, they are more effective in treating the eye than in the case of conventional drip infusion.
