Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eye drop container for injecting and dispensing a liquid eye drop stored in a container body.

[0002]

2. Description of the Related Art As a general eye drop container, there is a commercially available one in which a drop outlet for dropping an eye drop is provided in a synthetic resin container body for containing a liquid eye drop. In this eye drop container, the face is turned up, the cap body with the cap removed is picked with one finger, the drop outlet of the container body is pinched downward, and the eye drops pushed out of the container body are dropped. It is dropped from the exit toward the eyes.

[0003] In addition to the above-mentioned general-purpose eye drop containers in which eye drops are dropped and administered, eye drop containers capable of applying eye drops in various forms of use have been proposed. As a typical example, there is an eye drop container that injects eye drops using air pressure. As an example of such a container for eye drops, conventionally, (1) an inner stopper in which a hollow spray chamber is formed at an opening of a flexible synthetic resin container body for housing a liquid eye drop; The inner plug is formed with a spout capable of ejecting the compressed air in the container body toward the spray chamber when the outer surface of the container body is pressed with a finger with the opening side of the container body facing upward. And, one end side is fixed to a conduit extending to a position near the bottom in the container body, with the other end thereof positioned near the ejection port in the spray chamber, and further, in the spray chamber, An opening that ejects the eye drops that are pushed out from the other end of the conduit into the ejection chamber by the pressure of the compressed air into the ejection chamber and that is atomized by the compressed air ejected from the ejection port, as it is, laterally and outwardly, is inserted into the inner stopper. The formed eye drop container (for example, Japanese Utility Model Application Laid-open No. No. 191). (2) An opening for injecting the eye drops in the container body is provided at one end of the opening of the container body for storing the liquid eye drops, and
On the other end side, there were provided an air passage in which a rubber ball for sending compressed air toward the injection port was fixed, and an eye drop passage for guiding the eye drop in the container body to the middle of the air passage through a conduit. An eyedropper container provided with a stopper and configured to eject the eyedrops sucked into the air passage through the conduit and the eyedrops channel in the form of a mist from the outlet through the compressed air sent from the rubber ball ( See, for example, Japanese Utility Model Application Laid-Open No. 63-146653). The ones described in the above (1) and (2) have been proposed.

[0004]

However, in the case of the above-mentioned conventional (1), the elasticity of the container body after the injection of the eye drops causes at least an amount of air substantially equivalent to the volume of the air used for the injection. The outside air is sucked into the container body as it is through the opening and the spout, so that the eye drops in the container body are exposed to the sucked outside air, and a large amount of air in the container body is replaced every time the eye drops are sprayed. As a result, there is a problem that the eye drops in the container body are more likely to be contaminated by various bacteria mixed in the outside air.

[0005] In the case of the conventional (2), with the restoration of the elasticity of the rubber sphere after the eye drop is injected, an amount of outside air corresponding to the volume of air used for the injection is passed through the air passage into the rubber sphere. Since the air is sucked into the container, the outside air hardly enters the container body.Therefore, there is a low possibility that the eye drops in the container body are contaminated by various bacteria mixed in the outside air, but the rubber ball is connected via the stopper. Since the rubber ball protrudes outward from the container body, the rubber ball is easily caught by other objects when carrying it in a bag or pocket, and if the rubber ball is forcibly pulled out of the bag or pocket with the other object caught on the rubber ball May be detached from the stopper, and as a result, there is a problem that handling with care is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a main problem thereof is to rationally devise a structure of a container body in an eye drop container for injecting eye drops using air pressure. Accordingly, it is an object of the present invention to provide an eye drop container which is less likely to be contaminated by bacteria mixed in the outside air with the eye drop stored in the container body and is easy to handle when carried.

[0007]

According to a first aspect of the present invention, there is provided a container for an eye drop containing a liquid eye drop and an air chamber in a container body via a wall. A part or all of the air storage chamber-equivalent portion of the outer wall of the container main body is formed of an elastic body that can be elastically restored, and the air is pushed along with the pressing operation of the outer wall portion made of the elastic body. An injection port for injecting eye drops in the eye drop holding chamber is provided by air sent out from the holding chamber, and further, external air is sucked into the air holding chamber by elastic restoration of an outer wall portion made of the elastic body. There is a point. According to the above-mentioned characteristic configuration, the eye drops can be injected from the injection port portion by the air sent out from the air storage chamber by pressing the outer wall portion made of the elastic body, and the outer wall made of the elastic body can be injected. By the elastic restoration of the part, the outside air can be sucked into the air storage chamber. In addition, since the eye drop accommodating chamber and the air receiving chamber are formed so as to be separated from each other via the wall, the eye drops in the eye drop receiving chamber are not exposed to the outside air sucked into the air receiving chamber. Further, since the eye drop accommodating chamber and the air accommodating chamber are formed separately in the container main body via the wall, it is easy to form the external shape of the container main body into a simple shape that is difficult to be caught by other objects. Therefore, while being capable of injecting and administering the eye drops a plurality of times, the eye drops stored in the eye drop holding chamber are less likely to be contaminated by bacteria mixed in the outside air, and furthermore, bags, pockets, etc. Since it can be made hard to be caught by other objects even if it is carried in a portable device, it is easy to handle the portable device.

According to a second aspect of the present invention, there is provided a container for an eye drop, wherein a filter for permitting the passage of only air is provided between the eye drop chamber and the air chamber for storing liquid eye drops and air in the container body. A part or the entirety of the outer wall of the container body is formed of an elastic body that can be elastically restored, and the outer wall portion made of the elastic body is pressed together with the pressing operation of the outer wall part made of the elastic body. An outlet is provided for injecting the eye drops in the eye drop chamber with the air sent out from the air chamber, and the outside air is sucked into the air chamber by the elastic restoration of the outer wall portion made of the elastic body. The point is that it is configured as follows. According to the above configuration, when the outer wall portion made of the elastic body is pressed,
The air in the eye dropping chamber is sent to the air holding chamber through a filter that defines the eye drop holding chamber and the air holding chamber, whereby the air in the air holding chamber is sent out to the injection port, and the air in the eye drop holding chamber is also discharged. As the pressure of the air rises, the eye drops in the eye drop receiving chamber are also sent out to the injection port. In other words, the eye drops can be ejected from the injection port by the air sent from the air chamber only by pressing the outer wall portion made of the elastic body, and the elasticity of the outer wall portion made of the elastic body can be restored. Thereby, outside air can be sucked into the air storage chamber. In addition, since the eye drop storage chamber and the air storage chamber are defined through a filter that allows the passage of only air, even if various germs are mixed in the outside air sucked into the air storage chamber, the eye drop storage chamber and the air storage chamber may be mixed. The filter can prevent the germs from entering the eye drop holding chamber through the air holding chamber, and the eye drops held in the eye drop holding chamber do not leak into the air holding chamber. Further, the eye drop storage chamber and the air storage chamber,
Since the container body is formed by forming a partition through a filter that allows only air to pass through, the outer shape of the container body is easily formed into a simple shape that is difficult to be caught by other objects. Therefore, for example, the injection efficiency of the eye drops can be increased as compared with the case where the eye drops in the eye drop storage chamber are attracted and injected only by the air sent out from the air storage chamber. In addition, while being capable of injecting and administering eye drops a plurality of times, the eye drops stored in the eye drop holding chamber are not easily contaminated by various bacteria mixed in the outside air, and furthermore, bags, pockets, etc. Since it can be made hard to be caught by other objects even if it is carried in a portable device, it is easy to handle the portable device.

A third feature of the present invention resides in that a lid member for closing the opening of the injection port is swingably opened and closed and is pressed by air sent from the air storage chamber. It is configured to swing open and swing back to the closed position in response to the stoppage of the air supply from the air storage chamber. According to the above-mentioned characteristic configuration, it is possible to open the lid member with the air sent from the air storage chamber only by pressing the outer wall portion made of the elastic body, and to send out the air from the air storage chamber. Just by stopping, the lid member in the open position returns to the closed position and swings, so that the opening of the injection port can be opened and closed without touching the lid member.For example, the lid member can be opened and closed using a finger. The opening and closing operation of the lid member can be simplified as compared with the case of operation, and the finger accidentally touches the periphery of the opening of the injection port, thereby being contaminated with bacteria and the like attached to the finger. There is no.

[0010] According to a fourth aspect of the present invention, there is provided a container for eye drops provided with a foreign matter suction preventing filter for preventing foreign matter from entering the air containing chamber together with the outside air sucked into the air containing chamber. On the point. According to the above-described configuration, as the outside air is sucked into the air chamber, foreign bacteria such as bacteria mixed in the outside air and residual eye drops adhering to the injection port are sucked into the air chamber. ,
These foreign substances can be prevented from entering the air chamber together with the outside air by the foreign substance suction prevention filter.

According to a fifth aspect of the present invention, the eyedropper container is characterized in that the foreign matter suction prevention filter opens the air flow path when air is sent from the air storage chamber and the air storage space. The present invention is characterized in that the flow passage is closed as the outside air is sucked into the room. According to the above configuration, when the air is sent from the air storage chamber, the foreign matter suction prevention filter is opened, and the foreign matter suction prevention filter can be prevented from becoming a flow resistance of the delivery air. Of the eye drops can be suppressed, and a good eye drop injection state can be ensured. In addition, since the opened foreign matter suction prevention filter closes the flow path in accordance with the suction of the outside air into the air storage chamber, no foreign matter enters the air storage chamber with the suction of the outside air into the air storage chamber. Absent.

A feature of the eye drop container according to a sixth aspect of the present invention is that the direction of the opening of the injection port is configured to be changeable with respect to the container body. According to the characteristic configuration, the container body is gripped in a state where the outer wall portion made of the elastic body is easily pressed and the arm of the hand holding the container body is naturally bent to apply the eye drops to the container body. A comfortable posture that does not unnaturally twist the joints of the arms and hands by adjusting the direction of the opening of the injection port so that it faces the eyes in this state The eye drops can be ejected toward the eyes.
