Description

Eye drops container Field of invention

The present invention relates to an eye drop container for use in dropping a small amount of eye drops.

The present application claims priority from Japanese Patent Application No. 2013-023875, filed on Jan.

Background of the invention

In general, eye drops such as eye drops have various purposes of use, for example, a drug effect for removing itching or congestion of the eyes, or a relaxing effect of eliminating dry eyes or eye fatigue. The user should, under the intended use, use a sufficient amount of eye drops to absorb the degree of spillage from the eye, or consider the effect of not allowing the eye drops to adhere to it within the scope of the intended method of use. Eye drops are used in a variety of ways, such as dripping on the eye.

The eye drop container is widely used to design a container having a drop amount of 40 to 50 μL so as to be able to calm down the eye drops. However, the conjunctival sac in the surface of the eye has a capacity of approximately 30 μL. The volume of the conjunctival sac is estimated to be 5 to 10 μL in tear fluid. Therefore, the amount of the eye drops that can be retained on the surface of the eyeball is about 20 to 25 μL. Once the eye drops more than the eye of the retentive capacity Liquid, it may cause eye drops to overflow from the eyes and adhere to the eye area.

Therefore, the eye drops that overflow from the eyes sometimes become the cause of makeup removal. Therefore, it is desirable to be able to spot the eye drop container with a smaller amount and a positive amount of eye drops than the conventional eye drops.

Here, in the past, an eye drop container for dripping a small amount of eye drops on the eye has been developed, and a container which minimizes the amount of drop by one drop has been developed (for example, refer to Patent Document 1 below).

Patent Document 1 listed below discloses a chemical liquid container which is particularly preferable as a point eye. The liquid chemical container is coated with a substance having water repellency at a nozzle tip end seal portion inside the cover. The water-repellent substance is transferred to the front end side of the nozzle by the closing operation of the lid. Thereby, water repellency can be imparted to the front end of the nozzle, and the amount of dripping liquid can be controlled by a small amount and a drop amount.

Summary of invention

In the chemical liquid container of Patent Document 1 in which the water-repellent substance is transferred to the tip end of the nozzle, the water-repellent substance may be mixed into the eye liquid discharged from the tip end portion of the nozzle. In particular, when a small amount of eye drops are used, the safety or functional properties may be affected by the incorporation of water-repellent substances into the eye drops. Therefore, there is still room for improvement in the technique of applying the technique described in Patent Document 1 to the eye drop container for the purpose of dropping a small amount.

The present invention has been made in view of the above-mentioned matters, and it is possible to provide a water-repellent substance without using a water-repellent substance, and the amount of the eye drops discharged from the nozzle is less than 5 μL to 25 μL which is smaller than that of the conventional eye liquid container. The eye drop container which is easy for many users to operate is a problem.

In order to solve the above problems, the present invention achieves the above object and employs the following means.

(1) An eye drop container according to an aspect of the present invention, comprising: a liquid reservoir for storing eye drops; and a drip nozzle disposed to protrude above the liquid reservoir and to drop the aforementioned eye drops And a needle-shaped portion provided on the front end side of the aforementioned drip nozzle.

According to the above aspect, since the eye drops are dripped from the needle portion, a small amount of eye drops can be dropped.

(2) In the eye liquid container according to the above (1), the outer diameter of the needle-shaped portion is preferably 0.5 mm or more and 2.5 mm or less.

Thereby, the amount of each drop of the eye drops discharged from the needle-shaped portion (hereinafter referred to as the amount of dripping) can be reduced. Specifically, the amount of dropping of the eye drops can be 5 μL to 25 μL which is equivalent to about half or less of the dropping amount of the conventional eye liquid container.

(3) In the eye liquid container according to the above (1) or (2), the length dimension of the needle-shaped portion in the axial direction is preferably set to be 1 or more and 5 times the outer diameter of the needle-shaped portion. the following.

Thereby, even if the eye drops are dripped from the needle-like portion, the amount of dripping can be 5 μL to 25 μL less than that of the conventional eye liquid container. Further, before the eye drops are dripped on the proximal end side of the needle-shaped portion, the eye drops which are set in accordance with the outer diameter of the distal end of the needle-shaped portion can be dropped from the tip end of the needle-shaped portion. Specifically, when the front end of the needle-shaped portion faces downward (toward the eye), the inclination angle between the axis of the needle-shaped portion and the vertical direction is in the range of 0° to 80°, preferably 0° to 45°. If the posture of the eye liquid container is maintained as described above, the amount of dropping of the eye drops can be 5 μL to 25 μL. Further, if the angle is inclined, it is also advantageous for the eye liquid to be dripped on the base end side of the needle portion.

Thereby, since the needle-shaped portion is surrounded by the outer wall portion, the user can confirm that it is difficult for the front end of the needle-shaped portion to directly contact the eye. Therefore, the user can use the eye drop container with peace of mind, and can also prevent the needle portion from contacting the user's eyes or hands.

(5) In the eye liquid container according to the above (4), the outer wall portion is preferably provided in a part of the outer circumferential position or the entire circumference, or a part of the entire circumference, or a plurality of slits or a plurality of intervals. The aforementioned needle portion.

Thereby, since the outer wall portion is provided to surround the needle-shaped portion, it is possible to prevent the user's hand or the like from contacting the needle-shaped portion. Further, since the needle-shaped portion is surrounded by the outer wall portion, the user can easily recognize that the needle-like portion is difficult to contact the eyes. Further, the outer wall portion is provided in a part of the slit at the outer peripheral position of the needle-shaped portion, or is disposed at the outer peripheral position. When a plurality of the outer wall portions are provided at a part of the outer peripheral position, even if a little eye liquid adheres to the outer peripheral surface of the needle-shaped portion and flows to the proximal end side of the needle-shaped portion, it may be provided from the outer periphery. A portion of the position is discharged between the end edge or the outer wall portion of the outer wall portion.

(6) In the eye drop container according to the above (4) or (5), the outer wall portion is preferably provided in the drip nozzle.

Thereby, the outer wall portion can be provided without increasing the number of parts of the eye liquid container.

Detailed description of the preferred embodiment

Hereinafter, the eye drop container according to each embodiment of the present invention will be described with reference to the drawings.

(First embodiment)

First, a first embodiment of the present invention will be described. Fig. 1A is a cross-sectional view of the eye liquid container 1A according to the first embodiment of the present invention (a cross-sectional view of Fig. 1C as seen by the X1-X1 line arrow direction). Fig. 1B is a front view of the eye drop container 1A. Fig. 1C is a side view of the eye drop container 1A. As shown in FIGS. 1A to 1C, in the eye liquid container 1A, the drip nozzle 6A is provided in a liquid reservoir (also referred to as a container body) 2. 1A to 1C show the state in which the lid 3 is attached to the liquid reservoir 2 (the state in which the liquid reservoir 2 is closed).

The liquid reservoir 2 is provided with a reservoir (also referred to as a liquid accommodating portion) 4 for storing eye liquid inside, and a neck portion 5 which protrudes in a cylindrical shape upward from the upper end of the reservoir portion 4.

As shown in FIG. 1A, the storage portion 4 is provided with a lower wall portion 7 and from below. The peripheral edge portion 8 of the wall portion 7 is erected in a cylindrical shape, and an opening portion 9a for communicating the neck portion 5 is left to close the upper end portion 9 of the upper end portion of the side wall portion 8. This storage portion 4 is a space S1 for forming an eye liquid for internal storage. As shown in FIG. 1B and FIG. 1C, the side wall portion 8 is formed in a flat cylindrical shape and has a pair of flat plate portions 8T, 8T facing each other. The pair of flat plate portions 8T are portions where the user holds the storage portion 4.

As shown in FIG. 1A, the mouth-and-neck portion 5 is erected in a cylindrical shape from the periphery of the opening portion 9a formed in the upper wall portion 9. The inner hole 5a of the neck portion 5 communicates with the space S1 in the reservoir portion 4. The upper end of the mouth and neck 5 is open.

As shown in FIGS. 1A to 1C, a ridge 10 extending in the circumferential direction at a position opposite to each other is formed at a lower portion of the outer peripheral surface 5p of the neck portion 5. This ridge 10 is a to-be-locked part which locks the cover 3 mentioned later.

The reservoir 4 houses eye drops (eye drops) inside. Further, the eye liquid container 1A can also be applied to eye drops having high viscosity.

As shown in FIG. 1A, the drip nozzle 6A is a cylindrical member having a substantially circular cross section in which the eyelet droplet discharge path 11 penetrating in one direction is formed inside. The drip nozzle 6A is provided with an inner plug portion 12 inserted into the neck portion 5, and an upper end portion of the inner plug portion 12 for engaging the upper end surface of the neck portion 5 to form an annular outer wall portion 13 And the needle-like portion 14 which protrudes upward from the center of the plate surface of the overhanging wall portion 13 and drops the eye in the reservoir portion 4 (that is, discharges the eye drops to the outside). The drip nozzle 6A is formed by integrally forming the inner plug portion 12, the overhanging wall portion 13, and the needle portion 14.

The outer diameter of the inner plug portion 12 is approximately the same as the inner diameter of the neck portion 5. The outer wall surface of the inner plug portion 12 is in close contact with the inner wall surface of the mouth and neck portion 5.

As shown in FIGS. 1B and 1C, the diameter of the overhanging wall portion 13 is approximately the same as the outer diameter of the neck portion 5. The lower surface 13b of the overhanging wall portion 13 is an end surface 19 above the neck portion 5.

The overhanging wall portion 13 is formed with a needle-like portion 14 that protrudes upward in the vertical direction from the center of the upper surface in plan view.

The outer diameter of the needle portion 14 is not particularly limited, but is set to be in the range of 0.5 mm to 2.5 mm in the present embodiment. The shape of the needle portion 14 may be a slightly cylindrical shape, but it is considered that the needle portion 14 has strength and is slightly tapered.

Further, the length dimension of the needle-shaped portion 14 in the axial direction is not particularly limited, but in the present embodiment, it is set to a range of 3 mm to 10 mm. The length of the needle-like portion 14 in the axial direction is preferably 1 to 5 times the outer diameter of the needle portion 14, and particularly preferably 2.5 to 4 times the outer diameter of the needle portion 14.

The front end surface 14a of the front end of the needle portion 14 is formed to be slightly flat or curved.

As shown in FIG. 1A, the drip channel 11 of the drip nozzle 6A is formed so as to penetrate from the inner plug portion 12 through the needle portion 14 along the central axis L thereof. Further, the drip path 11 has a large diameter in the inner plug portion 12, and is tapered, and is gradually reduced in diameter from the overhanging wall portion 13 toward the front end of the needle portion 14. From the viewpoint of the molding method, the inner diameter of the dropping path 11 is set in the range of 0.15 mm to 2 mm in the needle portion 14. The shape of the drip path 11 in the needle portion 14 is a form in which a slightly inverted cone shape is formed.

However, the surface tension of the material of the nozzle member itself or contained in the container The specific gravity, viscosity, and surface tension of the eye drops are various values. Therefore, the amount of one drop discharged from the needle-like portion 14 can be adjusted to be about 5 μL to 25 μL smaller than that of the conventional eye liquid container, and in order to discharge such a small amount of droplets from the needle-like portion 14 in a stable manner, The area of the drip path 11 near the drip opening in contact with the eye drops should be as small as possible. Specifically, it is more preferable that the inner diameter of the drip path 11 in the vicinity of the drip opening is constant.

The lid 3 has a top plate portion 21 and a flat cylindrical shape that is suspended from the periphery of the top plate portion 21, and the side plate portions 22 that are opened downward are formed so as to hang down from the top plate portion 21 on the inner side of the side plate portion 22, and are mutually opposed. The grip wall portion 23 of the grip neck portion 5 and the grip portion 24 that protrudes downward from the center of the panel surface of the top plate portion 21 and have the insertion portion 27 into which the needle portion 14 is fitted are provided.

The grip wall portion 23 is formed in a circular arc shape in cross section by fitting the outer surface of the flat plate to the neck portion 5. A groove-shaped locking portion 25 for locking the locking portion formed by the protrusion 10 of the mouth-and-neck portion 5 is formed at a lower portion of the inner side surface of the grip wall portion 23.

Each of the configurations shown above has a relationship with each other as follows. In a state in which the lid 3 is installed in the liquid reservoir 2, the locking portion 25 provided in the grip wall portion 23 is locked to the engaged portion formed by the ridge 10. In the above state, the mouth-and-neck portion 5 is held by the grip wall portion 23. Further, the insertion hole 27 of the closing portion 24 is inserted into the front end of the needle portion 14, and the inner circumferential surface of the fitting hole 27 abuts against the front end of the needle portion 14 in a liquid-tight state. As a result, in the state in which the lid 3 is attached to the liquid reservoir 2, the opening of the dropping nozzle 6A is sealed in a liquid-tight state.

In the above configuration, the liquid reservoir 2 is formed of a synthetic resin material such as a polyester resin, a polyolefin resin, or a polystyrene resin. particular It is preferable to use polyethylene terephthalate, polypropylene, or polyethylene as a material of the liquid reservoir 2 from the viewpoint of easy availability. Further, as the material of the dropping nozzle 6A, polyethylene or polybutylene terephthalate or the like is preferably used from the viewpoint of easy availability.

Further, the needle portion 14 may be formed of a resin having flexibility that is elastically deformable. The soft elastic material which is elastically deformable is not particularly limited as long as it has elasticity and flexibility. However, it is preferable to have moldability, chemical resistance, and heat resistance without accompanying odor. Further, the needle-like portion 14 may be provided with antibacterial activity as necessary. In addition, considering the safety, it is suitable for the Japanese Ministry of Health, Labour and Welfare's Notice No. 65, and the sixteenth correction. The material of the Japanese Pharmacopoeia general test method should be used as the material of the needle portion 14.

Specifically, examples of the material of the needle portion 14 include a thermoplastic resin, a silicone resin, a thermoplastic synthetic rubber, a natural rubber, and a polyurethane rubber. The needle portion 14 can also be formed by combining these materials. Specifically, the material of the needle-shaped portion 14 is, for example, a TAFTEC (trademark registration) series H1052, H1053 manufactured by Asahi Kasei Co., Ltd., a Septon (trademark registration) series CJ001, CJ002, CJ101, or CJ102 manufactured by KURARAY. Other materials of the needle-like portion 14 include the LEOSTOMER series manufactured by RIKEN TECHNOS Co., Ltd., and the Sarlink (trademark registration) series 3140, 3160, 4155, and 4165 (olefin-based) manufactured by Toyobo Co., Ltd., and the like.

The hardness of the needle portion 14 is preferably 50 to 80 in accordance with JIS K6253 (type A hardness tester TYPE A DUROMETER). The tensile strength and elongation of the needle portion 14 is based on JIS K6253 (3rd dumbbell body) The measurement value of the (dumbbell) tensile speed of 500 mm/min is preferably 5 to 20 MPa, and the 300% tensile stress of the needle portion 14 is preferably in the range of about 1.5 to 5 MPa.

Further, when the needle-like portion 14 is formed of a resin having flexibility that is elastically deformable, as shown in FIGS. 6A to 6C, the base end portion 15 of the needle-like portion 14 may be formed with a large diameter, and the lid 3 may be closed. The portion 24 is in close contact with the peripheral surface of the needle portion 14 and the base end portion 15.

By forming the needle portion 14 and the closing portion 24 of the lid 3 in this manner, even if the needle portion 14 is formed of a material having flexibility, the drip nozzle 6A can be closed in a liquid-tight state at the end portion of the closing portion 24 before.

Moreover, considering the portability of the user, a smaller container structure is required as the structure of the eye liquid container 1A. Therefore, the capacity of the liquid reservoir 2 in the present embodiment is preferably 30 mL or less, more preferably 5 to 20 mL or less. Furthermore, it is preferable that the capacity of the liquid reservoir 2 is 5 to 10 mL.

Next, the method of using the eye liquid container 1A having the above configuration and the function and function when the eye liquid container 1A is clicked will be described.

As shown in FIG. 1B and FIG. 1C, when the eye drop container 1A is used by the user, the lid 3 is removed from the liquid reservoir 2. Then, in a state where the user grips the flat plate portions 8T, 8T of the side wall portion 8 of the liquid reservoir 2, the front end of the dropping nozzle 6A faces the eyes of the user located below. Thereby, the eye drops in the reservoir 4 flow toward the mouth and neck 5, and then enter the drip path 11 of the drip nozzle 6A as shown in FIG. 1A. The drip channel 11 has a large diameter formed in the inner plug portion 12, but has a reduced diameter in the overhanging wall portion 13, and is further formed extremely thin in the needle portion 14. therefore, The eye drops are not dripped a large amount from the needle portion 14 of the dropping nozzle 6A at a time, but are dropped from the needle portion 14 a small amount at a time.

Then, the outer diameter of the needle portion 14 is set in the range of 0.5 mm to 2.5 mm, and the length dimension of the needle portion 14 in the direction of the axis L is set to be in the range of 3 mm to 10 mm. Therefore, when the front end of the needle portion 14 is slightly downward, the inclination angle between the central axis L of the dropping nozzle 6A and the vertical direction is in the range of 0° to 80° (preferably 0° to 45°). Before the liquid is dripped in the direction of the base end portion of the needle portion 14, a droplet of 5 to 25 μL per drop can be dropped on the eye.

As described above, when the eye liquid container 1A is used, the front end of the needle portion 14 is inclined downward, and the eye drops are dropped at a time point of 5 μL to 25 μL. Therefore, the eye drops can be dripped within an appropriate amount, for example, which does not overflow from the eyes of the user. Moreover, since it is difficult to get wet around the eyes due to the eye drops, it is possible to prevent the user from being unpleasant. Moreover, if the eye liquid container 1A is borrowed, it is possible to prevent makeup removal around the eyes. Therefore, if the eye liquid container 1A is borrowed, it is possible to obtain an effect that the problem caused when the dropping amount of the eye liquid is more than a predetermined amount can be avoided.

Further, the length dimension of the needle portion 14 in the direction of the axis L is set to be in the range of 3 mm to 10 mm, and the inner diameter of the needle portion 14 is set in the range of 0.15 mm to 2 mm. In particular, when the inner diameter of the needle portion 14 is in the range of 0.15 to 1 mm, the eye drops can flow only a small amount at a time, and the eye drops of a predetermined amount or more become difficult to drip. Further, if the inner diameter of the needle-shaped portion 14 is larger than 1 mm and 2 mm or less, the orifice structure can be added, and similarly, the eye drops of a predetermined amount or more can be effectively prevented from dripping inadvertently. Therefore, it is possible to prevent the eye liquid from adhering to the needle portion 14 as much as possible, and to attach to the needle portion. A small amount of eye drops on the peripheral surface of 14 can be easily dried, so that it is possible to suppress the precipitation of components in the eye drops in the needle-like portion 14.

Moreover, when the eye liquid is filled into the liquid reservoir 2, it is necessary to sterilize the entire eye liquid container 1A. Sterilization is generally carried out by electron beam, gas (ethylene oxide, hydrogen peroxide, etc.), ozone, and heat. However, sometimes the surface tension of the material of the dropping path 11 which is the eye liquid containing the reservoir 4 or the needle-shaped portion 14 changes depending on the sterilization conditions, and the wettability of the liquid changes. Therefore, since the amount of one drop may vary due to the possibility of affecting the dripping of the eye drops, it is necessary to review the conditions suitable for sterilization. In particular, in the sterilization treatment using an electron beam, this phenomenon tends to be easily exhibited. Therefore, in the present invention, a method other than the electron beam is preferably selected as the sterilization treatment of the eye liquid container 1A.

Next, the second to fourth embodiments of the present invention will be described with reference to Figs. 2A to 5B. In each of the eye drops containers 1B to 1D of the second to fourth embodiments, as shown in the respective drawings, each of the eyelid containers 1B to 1D has a peripheral portion 14p interposed from the outer peripheral surface 14p of the needle-like portion 14 so as to surround a portion of the needle portion 14 or The outer wall portions 30B to 30D are erected in an entire manner.

In the following description, the same components as those of the above-described first embodiment and the embodiments to be described later are denoted by the same reference numerals, and the description thereof is omitted, and only the first embodiment or the first embodiment or The other embodiments are different from each other.
