FIG.

1 to 9, the present invention mainly includes a storage unit 100, a grip unit 200, and a discharge unit 300.

The storage unit has a sealed space for storing the eyedrops 10 therein, and a transfer tube 110 for transferring the eyedrops is provided at one side.

As shown in FIGS. 1 and 2, the storage unit may be formed of a synthetic resin material which is preferably harmless to the human body, and may be formed integrally with the grip unit and the discharge unit, which will be described later.

In addition, the transfer pipe may be formed in the form of a pipe inside the member between the storage unit and the discharge unit. However, in order to reduce the raw material in the manufacturing process, the thickness of the transfer pipe is smaller than the diameter of the transfer pipe The transfer tube may be formed protruding outwardly of the member.

In addition, the eye drops may be composed of a therapeutic agent (eye drop) or artificial tears in liquid form.

Meanwhile, the grip portion is formed to extend in a rectangular shape on one side of the storage portion so that the grip portion can be gripped by a user.

1, the grip unit may further include a display member 210 on which at least one product information 211 selected from a product name, a manufacturing component, a manufacturing date, a manufacturer, or an expiration date is printed .

That is, the display member is for facilitating the user to easily identify the product information at a glance.

The discharge unit 300 includes a discharge hole 310 connected to the transfer tube of the storage unit to discharge the eye drops to the outside, and a plurality of fine protrusions A nano pattern member 320 provided with the nano pattern member 321 is formed.

In addition, the discharge hole is formed at one end of the transfer tube, and preferably, the drop can be discharged in a direction perpendicular to the longitudinal direction of the transfer tube.

Further, the discharge hole preferably further comprises a funnel-shaped discharge surface 311 along the periphery.

At this time, the discharge surface is subjected to a hydrophilic treatment on the outer circumferential surface so that the eye liquid can stay on the discharge surface.

Further, the discharge surface preferably sets an appropriate discharge amount of the eye drop by adjusting the area of the discharge surface so that it is easy to cope with one proper dose of the different eye drops for each user.

As shown in FIG. 3, the nanopattern member may further include a plurality of ultrafine protrusions 322 on the outer circumferential surface of the microprojections.

Namely, such a nanopattern member is hydrophobic due to a phenomenon called a lotus effect, so that the liquid is concentrated in a droplet shape (or hemispherical shape) around the discharge hole.

As shown in FIG. 4, the nanopattern member is preferably formed with a sloped surface 323 curved toward the outer side with respect to the discharge hole.

That is, the fine protrusions and the ultrafine protrusions improve the cohesive force of the eye drops, but they become hydrophobic. When the eye drops are discharged above a certain standard, they can be easily detached from the nanopattern members. Allows safe dosing without escape.

5, the discharging unit may further include a cover unit 400 formed at one end thereof with a bending member 410 and connected to be diffractable by the bending member .

At this time, the bending member is preferably formed to be smaller than the thickness of the discharge portion and the cover portion so that the bending member can be bent easily, so that the cover portion can be easily diffracted.

In addition, the cover portion may be formed with a receiving groove 401 of a shape that is recessed to correspond to the shape of the nanopattern member of the discharge portion.

Such a receiving groove can completely seal the nanopattern member to prevent leakage to the outside of the eye drop.

In addition, the cover portion may have a plurality of coupling holes 420 protruding from one side or the other side of the outer peripheral surface, and the discharging portion may further include coupling holes 330 corresponding to the coupling holes.

FIG. 6A is a view showing a state in which the cover is opened; at the time of dosing, the cover is completely diffracted in the direction of the back surface of the nanopattern member so that the coupling is fastened to the coupling hole.

FIG. 6B is a view illustrating a state in which the cover portion is closed, so that the cover portion is diffracted in the direction in which the nanopattern member is positioned, so that the cover portion can be kept completely closed by the receiving groove.

In general, eye drops such as artificial tears are recommended for disposable use due to the risk of contamination from the outside. However, in the case of a common eye drop container, since the eye drops having a capacity for about 1 to 3 times are stored, The eye drops are reused up to twice or three times.

Therefore, the cover part completely hermetically closes the discharge hole and the nanopattern member through which the eye drops are discharged, thereby preventing contamination from the outside.

7, the cover includes a protruding cap 430 corresponding to the discharging hole on the inner circumferential surface of the receiving groove, and further includes an absorbing member 440 in the outer direction of the protruding cap .

At this time, when the cover part is closed, the protruding cap is inserted and fixed in the discharge hole to block the leakage of the eye drops through the discharge hole.

In addition, the absorbent member may be formed of an antibacterial fabric material, and absorbs the eye drops remaining on the nanopattern member after use of the eye drop.

The protruding cap and the absorbent member can minimize the contamination of the discharge portion even when the user uses the eye drop more than once.

As shown in FIGS. 8 to 9, the reservoir further includes a backflow preventing nozzle 120 for preventing the backwash of the eye liquid on the inner circumferential surface of the transfer tube,

The backflow prevention nozzle has a plate-shaped base member 121 corresponding to the inner circumferential surface of the transfer tube, a base member having a cut-out groove 122 formed in a central portion thereof, And a mesh member 123 formed on one side of the groove so as to open the incision groove only in one direction.

This backflow prevention nozzle has an advantage that it is easy to adjust the amount of the eye drop desired by the user as well as allowing the eye drop to remain in a state of being flocculated in the discharge portion even if the user does not press the storage portion after discharging the eye drop .

A method of using an eye drop container having an ejection portion with improved cohesion of an eye drop using the nano pattern according to the present invention will be described.

First, after the user completely opens the cover portion and completely diffracts the cover portion toward the back surface of the discharge portion, the coupling portion is inserted and fixed in the coupling hole.

Thereafter, the user grasps the grip portion and the storage portion to apply pressure to the storage portion at a distance that can be visually observed, so that the eye drops are discharged through the discharge hole and are discharged in the form of droplets by the nanopattern member having hydrophobicity with the discharge surface having hydrophobicity To be aggregated by the amount to be dosed.

Thereafter, when the discharge portion is brought into contact with the edge portion of the user's eye in a state in which the head is directed to the front without tilting the head backward like a conventional method of dropping the eye drops, the flocculated eye drops are naturally injected into the eye, So that the eye drops can be evenly spread by the blinking operation, thereby improving the convenience of the user.

As described above, according to the present invention, the nano-pattern member provided with the fine protrusions allows the discharge portion, which allows the eye drops discharged from the discharge hole to remain in a coagulated state, to contact the side of the eye of the user, .

In addition, the present invention can minimize the burden on the user's neck by the existing dropping method by allowing the eye drops for administration to the eye of the user to be concentrated on the mouth of the container by the nanopattern, It is easy to administer eye drops alone without the help of others.

Further, the present invention is advantageous in that a cover portion for sealing the discharge portion is formed to prevent the leakage of the eye drop and to prevent the discharge hole and the nanopattern member from being contaminated from the outside.
