- ophthalmic container a medical ophthalmic container for accommodating a medical ophthalmic solution so as to be instillable.
- a liquid injection cylinder is attached to a container body formed in a hollow cylindrical shape, and attached to the container body.
- a so-called three-piece type eye drop which is formed of three members as a whole eye drop including the cap, and as shown in FIG. 8, the liquid injection cylinder 6 and the container body 10 are blow-molded or vacuum-formed.
- the torso 2 of the eye drop container A (container main body 10) is gripped with two fingertips, and the eye drop container A is infused.
- the mouth 6a is held in the administration posture facing the eye to be administered, and while maintaining this posture, the body 2 is pressed toward the container axis, whereby the liquid medicine is supplied dropwise from the injection port 6a.
- the medicinal solution particularly a medical ophthalmic solution
- the eye drops described above are sterilized by steam sterilization or EO gas sterilization, etc.
- the chemical solution is sterilized by filtration sterilization using a membrane filter, etc. It is necessary to fill aseptically in a clean aseptic room.
- a cap is attached to the eyedropper to seal the eyedropper. This can prevent direct contact between the external air and the drug solution inside the eye drop container, so that the drug solution can normally be kept in a sterile state until the cap is released and the eye drops are applied. .
- a method is generally used in which the preservative is added to the medicinal solution and stored in the eyedropper container (preservation of the medicinal solution).
- eye drops containers that can securely maintain a sealed state until use are widely used, such as a completely integrated sealed eye drop container that does not have the above-mentioned injection port for discharging the drug solution in advance.
- a cap that can be suitably attached to such an eye drop container.
- the eyedrops be configured so that the sealed state can be reliably maintained until use.
- a first characteristic configuration according to the present invention includes, as shown in FIG. 1, a base member mountable on a container main body capable of storing a liquid,
- the base member is inserted and held so as to be slidable with respect to the base member;
- a pushing member having a groove on the side surface for guiding the liquid to the outside, and capable of being pushed toward the container body by the overcap which releases the sealed state of the container body;
- It has a first close contact member provided on the distal end portion of the base member so as to be in close contact with the pushing member from the outside and allow the outflow of the liquid.
- the contamination prevention cap of the present invention By configuring the contamination prevention cap of the present invention with the base member, the overcap, the pushing member, and the first close member, if the cap is attached to a container body containing a liquid, the container It is possible to adopt a configuration in which the hermetically sealed state is maintained until opening. This is for the following reasons.
- the container main body containing the liquid is a sealed container main body, and the cap is attached by attaching the base member to the sealed container main body.
- the cap is attached to the base member.
- the position of the pushing member is changed from a non-pushing posture in which the pushing member is not pushed into the container body to a pushing posture in which the pushing member is pushed into the container body by the overcap provided. Since the hermetically sealed state of the container main body is released, the liquid contained in the container main body can flow out of the container main body.
- the container main body containing the liquid is not limited to the container main body in a sealed state, and even if the liquid injection port is provided in advance, the push member is fitted into the liquid injection port to be in a sealed state until use.
- the operation of pushing the pushing member is not performed, so that the contact between the liquid before opening the container and the external air is prevented, and the container is securely held until the container is opened.
- the sealed state can be maintained.
- the cap is fitted into the container body, and the sealed state of the container body can be reliably released.
- the liquid that has flowed out of the container body is guided to the outside by a groove provided on the side surface of the pushing member. At this time, it is possible to prevent the liquid from flowing out through a path other than the groove. Therefore, liquid leakage from the container body during use can be suppressed.
- the first close member and the pushing member which are provided at the distal end portion of the base member and are in close contact with the pushing member from the outside, are easily formed by the pressure of the liquid guided by the groove. Since the liquid is separated from the liquid, the liquid can be discharged to the outside, so that the liquid can be easily provided.
- the cap of this configuration After the desired amount of liquid has flowed out, when the pressing of the body of the eyedropper is stopped, the first close member and the pushing member return to the close contact state. At this time, it is possible to prevent external air from flowing into the eyedropper. Therefore, by applying the cap of this configuration, the path through which the external air flows into the container body after the desired amount of liquid has flowed out is blocked, so that the microorganisms contained in the external air after the container is opened are opened. And the like can be prevented from being taken into the ophthalmic container, and contamination of the container after opening the container can be prevented.
- a second special configuration according to the present invention is that, as shown in FIG. 1, the pushing member has a needle-shaped one end on the container body side. It is.
- the pushing member is moved from the non-pushed posture.
- the sealed state can be easily and reliably released by changing the posture to the pushing posture.
- a protrusion for suppressing deformation of the first close member toward the base member side is dispersedly disposed at a tip end portion of the base member. And the protruding portion is located close to the first close member, and the operation and effect are as follows.
- the first close member When the pushing member is in the pushing posture, the first close member may be deformed toward the base member due to friction between the pushing member and the first close member. However, when the first close member is deformed to the base member side, the protruding portion is formed on the base member. • If they are distributed at the distal end, the first close member, the protruding portion, and the periphery of the distal end of the base member are almost evenly in contact with each other. For this reason, even if the first close member is deformed, it is difficult to cause irregular deformation. Therefore, it is possible to prevent the chemical solution from flowing out unevenly.
- a fourth characteristic configuration according to the present invention is that, as shown in FIG. 6, a sealing member held by the pushing member and the base member is provided in a state where the pushing member is pushed.
- the base member and the eye drop container for example, the inner plug
- the base member and the eye drop container come into contact with each other.
- the base member and the inner plug portion are not tightly adhered, there is a possibility that external air flows in.
- the sealing member is held by the pushing member and the base member in a state where the pushing member is pushed, so that when the pushing member is in the pushing posture, the sealing member is pushed by the pushing member. It will be pressed. Therefore, the pressing of the sealing member can be avoided until the time of use, so that the shape of the sealing member and the external air blocking function can be stored well without deterioration until the time of use.
- a fifth characteristic configuration according to the present invention is that, as shown in FIG. 7, the base member is composed of a first base member and a second base member, and is in a state before the pushing member is pushed.
- the outer periphery of the sealing member is fixed by the first base member and the second base member, and the operation and effect are as follows.

Therefore, it is possible to prevent the sealing member from being held in the abnormal posture by the first base member and the second base member when the pressing member is in the pressing posture, and the external air blocking function can be prevented. Can be reliably demonstrated.
- a sixth characteristic configuration according to the present invention is that, as shown in FIG. 2, the overcap is formed of a cap body and a cutout part that can be cut off from the cap body, and after removing the cutout part, The point is that the cap body is configured to be able to come into contact with the base member when the cap body is pushed in.
- the operation and effect are as follows. That is, since the overcap is formed by the cap body and the cutout part cut off from the cap body, the cap body is placed on the container body side unless the cutout part is removed from the cap body. It cannot be pushed in (pushed posture).
- the cutout portion is in contact with the base member, so that the pushing member can be prevented from being pushed in. Further, when using the eye drop container, the cap is used. Since the body is in contact with the base member, the pushing member can be prevented from being pushed more than necessary.
