The embodiment shown in FIG. 1 relates to a container for containing eye drops. This container has a container body 1 containing a sterilized eye drop A and a cap 3 which is detachably attached to the container body 1.

The container body 1 is made of an elastically deformable material. Specific examples of the material include polyolefin resins such as polyethylene and polypropylene, and synthetic resins such as polycarbonate and polyester.

An annular convex portion 1a is provided on the outer peripheral surface of the container body 1, and a first annular concave portion 3b is provided on the inner peripheral surface of the cap 3 near the open end 3a. When the cap 3 is attached to the container 1, the first annular recess 3b of the cap 3 fits into the annular protrusion 1a of the container body 1, so that the cap 3 is fixed to the container body 1 so as not to fall off. When removing the cap 3 from the container body 1, if the container body 1 and the cap 3 are pulled in directions away from each other, the annular projection 1a of the container body 1 and the first annular recess 3b of the cap 3 are fitted together. After the state is released, the cap 3 can be removed from the container body 1. In the illustrated embodiment, the first annular convex portion 1a is provided on the outer peripheral surface of the container body 1 and the annular concave portion 3b is provided on the inner peripheral surface of the cap 3, but the annular convex portion is formed on the inner peripheral surface of the cap 3. It may be provided on the surface and the annular recess may be provided on the outer peripheral surface of the container body 1.

A liquid discharge part 5 is press-fitted into the opening 1b of the container body 1. The liquid discharge part 5 is composed of a porous body having a large number of fine flow holes (not shown) through which the eye drop A contained in the container body 1 can pass. By pressing the elastically deformable container body 1, the eye drop A contained in the container body 1 can be ejected through the flow hole of the liquid ejection part 5.

Inside the cap 3 which is detachably fitted to the container body 1, when the cap 3 is fitted to the container body 1, the outer surface 5a of the liquid ejecting portion 5 is liquid-tightly covered and An antibacterial contact member 7 that is in intimate contact with the outer surface 5a of the liquid ejecting portion 5 and can propagate an antibacterial action to the liquid ejecting portion 5 exposed to the outside air is movably arranged in the vertical direction. There is. More specifically, a second annular recess 3c extending in the vertical direction is formed on the inner peripheral surface of the side wall of the cap 3, and the contact member 7 is provided with a flange 7a.
The contact member 7 is supported by the cap 3 so as to be vertically movable along the second annular recess 3c by loosely fitting the flange portion 7a into the second annular recess 3c of the cap 3. The surface 7b of the contact member 7 that is in contact with the liquid ejection portion 5 can be brought into close contact with the outer surface 5a of the liquid ejection portion 5 so that the outer surface 5a of the liquid ejection portion 5 can be intimately contacted.
Is formed in a shape corresponding to.

The contact member 7 may itself be made of an antibacterial material, or the base member made of a material described later may be subjected to an antibacterial treatment by using an antibacterial material. It may have sexual characteristics. The material forming the above-mentioned base body of the contact member 7 may be a hard material such as hard plastic, metal, resin or a sintered body of metal, ceramics, or ceramics. In the case of making a close contact, it is preferable that the contact member 7 is made of a material that can deform when the contact member 7 comes into contact with the liquid ejection portion 5. Particularly, an elastically deformable material is preferable, and specific examples thereof include urethane, ethylene-vinyl acetate copolymer, other soft plastics, resins such as foamed plastics, woven cloth, non-woven cloth, cotton, rubber and the like. You can

The antibacterial material needs to be capable of exerting a bacteriostatic or bactericidal effect on microorganisms, but the contact member 7 discharges the eye drop A contained in the container body 1. Since it comes into contact with the liquid ejecting section 5,
It is also necessary that the material be less toxic to the human body even if it is dissolved in the eye drop A adhered to the liquid ejection portion 5. Specifically, compounds containing heavy metals such as gold, silver, copper, titanium, platinum, zinc and mercury, and heavy metals such as silver chloride, silver nitrate, mercuric chloride, titanium oxide and organic mercury (thimerosal) (hereinafter, "Heavy metals"), chlorhexidine gluconate (trade name "HIBIDEN"), benzalkonium chloride,
Organic substances such as biguanides and quaternary ammonium salts, various antibiotics, and the like, which are not easily soluble in the eye drop A contained in the container body 1, are preferable. Here, the term “easily soluble” means that the amount of eye drops required to dissolve 1 g of the solid of the antibacterial material has a solubility of less than about 30 ml.

Among the above-mentioned antibacterial materials, the heavy metals are capable of exhibiting bacteriostatic or bactericidal action by the solids themselves, and are produced by being eluted from the heavy metals in an extremely minute amount of several ppb to several + ppb. Heavy metal ions have a strong affinity for proteins of microorganisms and can kill microorganisms, and thus are suitable as an antibacterial material used in the present invention. Further, among the heavy metals, gold, silver, copper, zinc and their compounds, particularly silver / silver compounds, are preferable because they have particularly low toxicity to the human body. Examples of silver include metallic silver and colloidal silver, and examples of the silver compound include silver halides such as silver chloride, silver bromide and silver iodide, silver sulfate, silver phosphate, silver sulfide, and the like. Examples thereof include silver chlorate, silver silicate, and silver oxide.

As a method of subjecting the base of the contact member 7 to antibacterial treatment with an antibacterial material, for example, a method of kneading the antibacterial material into the base, a method of coating the antibacterial material on the base, or a material constituting the base is used. A method of mixing the antibacterial material and molding the contact member 7 may be used. Examples of the method for coating the base of the contact member 7 with heavy metals include, for example, a method of subjecting the base to ion plating with heavy metals, immersing the base in an aqueous solution of a heavy metal salt, adding an alkaline solution thereto, and heating. A method of depositing heavy metals on the surface of the substrate by reduction, a method of plating the substrate with heavy metal, or the like can be used. Further, in order to mix the antibacterial material with the material forming the base to form the contact member 7, for example, the powder of the material forming the base is mixed with the powder of heavy metals to form the contact member 7, or Further, a method of performing sintering treatment can be adopted.

In the present invention, a device is provided for pressing the contact member 7 against the outer surface 5a of the liquid ejection portion 5 when the cap 3 is fitted to the container body 1. As a device for this, the contact member 7 can be embodied as a base body made of an elastic material such as rubber described above and subjected to antibacterial treatment. According to this structure, when the cap 3 is fitted to the container body 1, the contact member 7
While being pushed by the liquid discharge part 5, it moves in the direction of the closed end 3d of the cap 3 along the second annular recess 3c of the cap 3 and is pressed against the closed end 3d of the cap 3, and eventually the cap 3 The first annular concave portion 3b is fitted into the annular convex portion 1a of the container body 1, and the cap 3 is fitted into the container body 1. In this state, the elastic force of the elastic material forming the contact member 7 presses the contact member 7 against the outer surface 5a of the liquid ejection portion 5, so that the antibacterial action of the contact member 7 is exerted on the liquid ejection portion 5. Will be able to spread powerfully.

Further, as shown in FIG. 2, the base 7c of the contact member 7 is made of a hard material that has been subjected to antibacterial treatment as described above, and the base 7c made of the hard material is located outside the liquid discharge portion 5. An elastic body 7d such as rubber may be attached to the surface opposite to the surface 7b in contact with the surface 5a. Also in this case, since the elastic body 7d of the contact member 7 is pressed against the closed end portion 3d of the cap 3 when the cap 3 is fitted to the container body 1, the elastic force of the elastic body 7d causes the contact member to contact the contact member. 7 is pressed against the outer surface 5a of the liquid ejection portion 5.

Further, as shown in FIGS. 3, 4 and 5, the contact member 7 is made of a hard material that has been subjected to antibacterial treatment, and the inner surface of the closed end 3d of the cap 3 and the contact member 7 are connected to each other. By disposing the elastic rubber body 9, the leaf spring 11, and the coil spring 13 as an elastic body,
The contact member 7 may be configured to be pressed against the outer surface 5a of the liquid ejection portion 5 by the elastic force of the elastic body when the cap 3 is fitted to the container body 1.

In the example shown in FIG. 3, when the cap 3 is fitted to the container body 1, the contact member 7 is pushed by the liquid discharge part 5 and along the second annular recess 3c of the cap 3. The elastic rubber body 9 is moved toward the closed end portion 3d of the cap 3 and the elastic body 9 is moved to the closed end portion 3d of the cap 3.
To the first annular recess 3b of the cap 3 in due course.
Is fitted with the annular convex portion 1a of the container body 1, and the cap 3
Is fitted to the container body 1. In this state, since the contact member 7 is pressed against the outer surface 5a of the liquid ejection portion 5 by the elastic force of the rubber body 9, the antibacterial action of the contact member 7 can be strongly spread to the liquid ejection portion 5. become able to.

In the example shown in FIG. 4, the leaf spring 11 is formed in a side surface having a substantially inverted Ω shape, and has a ring-shaped main body portion 11.
a and a pair of legs 11b extending laterally from the ring-shaped body 11a. The leaf spring 11 is attached to the cap 3 by supporting the leg portion 11 b on the side wall of the cap 3. Also in this example, as in the above-described example, when the cap 3 is fitted to the container body 1, the contact member 7 is against the outer surface 5a of the liquid ejection portion 5 by the elastic force of the leaf spring 11. Since the contact member 7 is pressed, the antibacterial action of the contact member 7 can be strongly propagated to the liquid ejection portion 5.

Also, in the example in which the conical coil spring 13 is arranged between the inner surface of the closed end 3d of the cap 3a and the contact member 7 as shown in FIG.
The contact member 7 is pressed against the outer surface 5 a of the liquid ejection portion 5 by the elastic force of the coil spring 13 when the contact member 7 is fitted to the container body 1. In the example shown in FIG. 5, the coil spring 13 is supported by the pin 15 attached to the closed end 3d of the cap 3.

Further, as shown in FIG. 6, a threaded pin 17 is inserted into the cap 3 through the closed end 3d of the cap 3.
The shaft portion 17a may be screwed and the pressing plate 19 may be provided at the lower end of the shaft portion 17a. In this example,
After the cap 3 is fitted to the container body 1, the user can rotate the knob portion 17b of the pin 17 to move the pressing plate 19 downward, so that the pressing plate 19 causes the contact member 7 to move the contact member 7 to the liquid ejecting portion 5. Can be pressed against the outer surface 5a.

Further, as shown in FIG. 7, by adopting a pair of magnet bodies 21 and 23 having the same poles opposed to each other, the magnet body 21 having the same poles opposed to each other is employed. , 23, the contact member 7 may be pressed against the outer surface 5a of the liquid ejection portion 5. More specifically, the first magnet body 21 is mounted on the inner surface of the closed end portion 3d of the cap 3 such that the N pole thereof faces the contact member 7, and the second magnet body 23 is mounted on the inner surface of the closed end portion 3d. The north pole is embedded in the contact member 7 so as to face the north pole of the first magnet body 21. In this example, cap 3
Is fitted to the container body 1 and the first annular recessed portion 3b of the cap 3 is fitted to the annular protruding portion 1a of the container body 1, the first magnet body 21 and the second magnet body 23. The contact member 7 is pressed against the outer surface 5a of the liquid ejection portion 5 by the magnetic repulsive force generated between the contact member 7 and the liquid ejection portion 5. Therefore, also in this liquid container, the antibacterial action of the contact member 7 can be strongly propagated to the liquid ejection portion 5.

Examples of the material forming the liquid ejecting section 5 include glass fiber, metal, ceramics or ceramics, natural or synthetic polymer, and the like. The liquid discharge part 7 includes a metal sintered body such as brass and stainless steel, a ceramic sintered body, a resin sintered body such as ultra high molecular weight polyethylene,
It can be composed of a woven or non-woven fabric of natural fibers or synthetic fibers, a membrane filter of polycarbonate, polytetrafluoroethylene, cellulose mixed ester, cellulose acetate or the like. Among these materials, the sintered body is preferable as the material of the liquid ejection portion 5 from the viewpoint that it can be easily manufactured. Further, the material forming the liquid ejecting section 5 may be a hydrophilic material or a water repellent material, but when the average hole diameter of the flow holes of the liquid ejecting section 5 is extremely fine. In order to allow the eye drop to pass through the liquid discharger 5,
It is preferable that the liquid ejection portion 5 is made of a hydrophilic material. Furthermore, when the liquid ejection portion 5 is made of a water-repellent material, the liquid A is less likely to remain in the liquid ejection portion 5,
It is possible to prevent microorganisms from passing through the flow holes.

When the user loosens the pressing force on the container body 1 after the container body 1 is pressed and deformed and before the cap 3 is fitted, the container body 1 made of an elastically deformable material is elastically deformed. Restore by force. At this time, due to the restoration, the outside air is sucked into the container body 1 through the hole of the liquid ejection portion 5, and accordingly, the microorganisms attached to the liquid ejection portion 5 and the microorganisms in the outside air are taken into the container body 1. There is a risk of being. However, after instillation, the cap 3 is attached to the container body 1
If the user loosens the pressing force on the container body 1 after fitting the container into the container body (hereinafter referred to as “preferred usage form”), external air will not be sucked into the container body 1 and thus the uptake of microorganisms. Can be prevented.

Assuming a situation in which the user loosens the pressing force on the container body 1 before the cap 3 is fitted on the container body 1 to suck the outside air into the container body 1, the liquid ejecting section is assumed. The average pore diameter of a large number of 5
It is preferable to set the size so that the passage of the eye drop A can be permitted while the passage of the microorganisms can be blocked. Specifically, the pore size is 0.1 μm or more and 1.2 μm or less, more preferably 0.65 μm or less,
More preferably, it is 0.22 μm or less. Liquid ejector 5
By setting the pore diameter of the container to such a specific size, the microorganisms are not taken into the container body 1 even if the user does not use the container in a preferable usage form. Microorganisms that have been prevented from passing through the liquid discharger 5 are captured on the outer surface of the liquid discharger 5, so that the contact member 7 that comes into contact with the outer surface of the liquid discharger 5 by fitting the cap 3 onto the container body 1 By the antibacterial action of, the captured microorganisms can be bacteriostatic or sterilized. Therefore, if the container body 1 and the eyedrops A are sterilized in advance, the eyedrops A in the container body 1 are microbial cells even if a preservative is not mixed in the eyedrops unlike the conventional eyedropper containers. It can be used repeatedly without being contaminated by the preservative, and the side effect of the preservative does not affect the user.

Further, in consideration of the above-mentioned adverse effects due to the intake of outside air due to the restoration of the container body 1 due to the release of the pressing force against the container body 1, the container body 1 is pressed to discharge the liquid A from the liquid discharge part. The liquid delivery mechanism can be incorporated into the container body 1 without adopting the structure of allowing the liquid to flow out from the container 5.

As this liquid delivery mechanism, a piston mechanism 50 as shown in FIG. 8 can be adopted.

The second portions 10b are screwed together to form the container body 1. A knob 58 is attached to the end of the piston rod 52 protruding outward from the container body 1.

In a container employing the piston mechanism 50, when the user grips the knob 58 and pushes the piston rod 52 toward the liquid discharge part 5 while rotating the piston rod 52, the piston head 54 slides on the wall surface of the container body 1. The eyedrops A move while coming into contact with each other so that the eyedrops A flow out from the liquid ejecting section 5. With this structure, the outside air is not taken into the container body 1 through the holes of the liquid ejection portion 5. In the container provided with the liquid delivery mechanism, the container body 1 is not limited to an elastically deformable material, and can be made of any other suitable material.

Further, as shown in FIGS. 1 to 8, a porous filter member 30 may be interposed between the container body 1 and the liquid discharge part 5. The filter member 30 is a porous filter that allows passage of aseptic eyedrops A but blocks passage of microorganisms, covers the entire surface of the opening 1b of the container body 1, and places it between the opening 1b and the opening 1b. It is fixed to the container body 1 by means such as adhesion or welding so as not to form a gap through which the eye drop A and the outside air can pass. Porous filter 3
When 0 is attached, the liquid ejection portion 5 is press-fitted into the opening 1b of the container body 1 so that the liquid ejection portion 5 is arranged in close contact with the liquid ejection side surface of the filter member 30.

The material of the filter member 30 is woven or non-woven fabric of natural fiber or synthetic fiber, polyethylene,
A membrane filter made of a synthetic resin such as polycarbonate, polyvinylidene fluoride, polytetrafluoroethylene, nitrocellulose, cellulose mixed ester, or cellulose acetate can be used.

The filter member 30 is capable of blocking the passage of microorganisms and at the same time allowing the eye drop A of the container body 1 to pass therethrough.
The average pore diameter of the flow holes is 0.1 μm or more and 1.2 μm or less,
It is more preferably 0.65 μm or less, still more preferably 0.
22 μm or less. When the average pore diameter of the flow holes of the filter member 30 is particularly fine, it is preferable that the filter member 30 is made of hydrophilic synthetic resin.

In the embodiment described above, the contact member 7
However, the liquid discharge part 5 through which the eye drop A passes is also configured to have the antibacterial property by using an antibacterial material that is hardly soluble in the eye drop A. You can also In this case, in addition to the antibacterial action of the contact member 7, the antibacterial action of the liquid ejection unit 5 is added, so that the bacteriostatic or bactericidal effect of the liquid ejection unit 5 can be improved. Here, the antibacterial material having a low solubility in the eye drops means that among the antibacterial materials used for the contact member 7, when the eye drops are brought into contact with the eye drops in a solid state, they are not dissolved in the eye drops at all, or It refers to a material that dissolves in a trace amount, and for example, a material that has a solubility to the extent that 1 g of solid antibacterial material does not dissolve in 10000 ml or more of eye drops. Also,
