SOLUTION: The inner plug capable of dropping contents from a mouth part by corresponding with the mouth part of a container comprises a nozzle part 2a which is fitted and maintained in a mouth part 1a of a container 1 and has an opening C dropping the contents inside the container, and a flange part 2b which is integrally connected with the periphery of this nozzle part 2a and prevents the nozzle part from coming into contact with a dropping object.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inner plug suitable for being applied to a container filled with a drug solution such as eye drops and the like. It is intended to surely prevent foreign matter from being mixed into the container.

[0002]

2. Description of the Related Art A container for filling a drug solution such as eye drops or the like is provided with an inner stopper formed at a mouth thereof, which has a dropping path formed along an axis so that one or several drops can be dropped at a time. Have been.

[0003] Usually, when this kind of container is used as an eye drop container, an eye plug (eyeball) is used when the eye drop is applied.
It is common to drop the drug solution at a certain distance from the eye, but some users apply the tip of the inner plug directly to the eye (the outer corner of the eye, the inner corner of the eye, the upper and lower eyelids, or the eyeball) when instilling it. There is. By the way, such eye drops occur when a so-called container vacuum action (which is large when the container body is squeezed) occurs, in which external air is sucked into the container through the drip path of the inner stopper as the liquid medicine is discharged. In some cases, the chemical may flow into the container together with foreign matter such as eye repellent adhered to the tip of the inner plug to contaminate the chemical solution. This may lead to a complaint from the user that the substance is a foreign substance originally mixed in the chemical solution, and a solution is desired.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a new inner plug which can reliably prevent foreign matter from entering the container even when the inner plug is brought into contact with the object to be dropped. The proposal is about the structure.

[0005]

According to the present invention, there is provided an inner plug adapted to be fitted to a mouth of a container and capable of dripping contents from the mouth, wherein the inner plug is provided at the mouth of the container. A nozzle portion that is fitted and held and has an opening through which the content in the container is dropped, and a flange portion that is integrally connected around the nozzle portion and that prevents the nozzle portion from coming into contact with an object to be dropped. It is particularly preferable that the flange portion has a rounded end, in order to provide a soft feeling when the flange portion comes into contact with an object to be dropped.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described more specifically with reference to the drawings. FIG. 1 shows a configuration in which the inner plug according to the present invention is applied to an eye drop container, and FIG. 2 is a view showing a state where a sealing stopper (cap) over the inner plug is removed.

In the figure, reference numeral 1 denotes a container for filling a chemical solution, and reference numeral 2 denotes an inner plug adapted to the mouth 1a of the container 1 and capable of dropping the chemical from the mouth 1a.

The inner plug 2 is fitted into and held by the mouth of the container 1 and a flange portion 2b integrally connected around the nozzle portion 2a to prevent the nozzle portion 2a from coming into contact with an object to be dropped. An opening C for dropping is provided at the tip of the nozzle portion 2a.

Reference numeral 3 denotes a hermetically sealed stopper that can be screwed and fixed at the mouth 1a of the container 1 over the inner stopper 2. The sealing plug 3 can be provided with a convex portion 3a that fits into the opening C of the nozzle portion 2a, and the sealing portion 3 can be tightly sealed by fitting the convex portion 3a to the opening C by tightening the sealing plug 3. .

FIG. 3 shows a state in which eye drops are applied using the eye drop container having such a configuration. When the eye drop is applied, the flange portion 2b of the inner plug 2 is brought into contact with the outer corner of the eye and the like, and the eye and the opening C of the nozzle portion 2a are kept at a fixed interval, so that foreign matter such as eye stains can adhere to the site. Absent.

As shown in FIG. 4, it is a matter of course that the inner plug 2 can adopt a general eye drop method in which the inner plug 2 is dropped at a fixed distance from the eye to drop a chemical solution.

FIGS. 5 and 6 show other examples of the inner plug according to the present invention. FIG. 5 shows a stored state and FIG. 6 shows a usable state.

In the inner plug 2 shown in FIGS. 5 and 6, a flange portion 2b is provided at the tip of the nozzle portion 2a, and the opening C is located inside the flange portion 2b.

In the inner plug 2 having such a configuration, as shown in FIG. 7, the nozzle portion 2a does not erroneously come into contact with the dripping target at the time of instillation, and the opening C and the dripping target are fixed. , The foreign matter does not penetrate into the container when the vacuum action of the container occurs.

The inner plug 2 as shown in FIGS. 5 and 6 allows a chemical solution to be dripped along the flange surface, so that a smooth supply of the chemical solution is possible. However, as shown in FIG. Needless to say, they can be instilled.

The inner plug according to the present invention may be a water-repellent resin such as polyethylene resin or polypropylene resin (soft), polybutylene terephthalate resin, or nylon suitable for allowing the contents to smoothly flow down to the tip of the container. Etc. can be applied, but the material is not particularly limited.

[0017]

According to the present invention, even when the inner plug is brought into contact with the object to be dropped, the tip of the flange portion comes into contact with the object, so that the foreign matter can be inserted into the opening of the inner plug. There is no adhesion of foreign substances into the container, and the quality of the contents can be maintained for a long period of time.
