Abstract

(57) [Summary] [Purpose] After extracting the droplets in the droplet extraction container,
It is an object of the present invention to realize a container in which all the liquid retained in the nozzle conduit can be completely re-stored in the container body. [Structure] When the container body is made of a flexible material, a concave portion is provided in the container body and the container body is pushed and expanded after use. By providing a bellows-like body on the outer wall and opening it after use, the volume of the container body is changed to achieve the purpose.

Description

[Detailed description of the device]

[Industrial applications]

 The present invention relates to a droplet extracting container used for extracting a desired number of droplets of a liquid contained in a container body into droplets of a desired size. More specifically, the present invention relates to a droplet extracting container characterized in that a mechanism for adjusting the gas pressure in the container is provided in the container body.

[0002]

[Prior art]

 It has been widely practiced in the past to separate a liquid used for medical treatment and hygiene as droplets and supply a desired amount of the liquid to a desired location. With the recent improvement in living standards, such technologies have come to be widely used not only in the leading edge of medical care and hygiene but also in our daily lives. For example, the most prominent example is the use of eye drops, but another thing that has come into widespread use recently is the use of small contact lenses for cleaning and wearing contact lenses. The desired amount of washing liquid or washing water must be supplied on top of.

In such a case, the container containing the liquid that is normally used is tilted and connected to the container body, and the liquid is introduced into a nozzle-shaped conduit that gradually becomes thinner as it is installed at the end of the container. Droplets are extracted from the tip of the conduit and the desired amount of liquid is supplied to the desired locations such as the eyes and contact lenses.

When it is required to supply a required amount of liquid to a required place in this way, the higher the required accuracy is, the smaller the size of the extracted droplet becomes. As a result, the inner diameter at the tip of the nozzle-shaped conduit is required to be smaller and thinner, and the length of the nozzle-shaped conduit tends to be inevitably longer.

However, as the length of the nozzle-shaped conduit becomes longer, the nozzle is not re-stored in the container body after use, which has been heretofore cited as a problem of such a droplet extracting container. The amount of the liquid that remains in the tubular conduit increases, which is uneconomical and not only considered hygienic, but also the risk of contamination by miscellaneous bacteria, etc. Problems such as not only the extraction container itself but also the surrounding area are becoming more and more important.

[0006]

[Problems to be solved by the device]

 The present inventor has diligently studied to solve the above-mentioned drawbacks of the prior art and to develop a method for completely re-containing all the liquid retained in the nozzle-shaped conduit after use in the container body. I came to complete the idea.

[0007]

[Means for Solving the Problems]

 The gist of the present invention is to completely re-store all the liquid accumulated in the nozzle-shaped conduit after the use of the droplet extracting container in the container body. For this purpose, it is necessary to break the balance between the external air pressure exerted on the liquid accumulated in the nozzle-shaped conduit and the gas pressure in the container body. It is proposed as a means to solve this problem by providing the container body with a mechanism that changes the volume of the container slightly.

That is, as a mechanism for changing the volume of the container body proposed by the present invention, specifically, when the container body has flexibility and is made of a flexible material such as a synthetic resin, By providing a recess in the container body and pressing the container body between the thumb and the other four fingers of the hand after use to inflate the recess and consequently change the volume of the container. The gas pressure in the container body is reduced and the liquid retained in the nozzle-shaped conduit is stored again in the container body.

If the container body is not flexible and is made of a very hard material such as a synthetic resin that is hard to bend or does not bend at all, a bellows is formed on a part of the outer wall portion of the container body. When the container itself is used, the bellows-shaped body is closed while the container itself is in use.However, when treating the accumulated liquid in the nozzle-shaped conduit after use, it feels like bending the entire container body. By opening the bellows, the volume of the container body is changed to achieve the purpose.

【Example】

 Next, the present invention will be described by way of examples, but the present invention is not affected by this.

Various types of droplet extracting containers according to the present invention are provided, but generally, a nozzle-shaped conduit is integrally formed on a conical or cylindrical container body, or It is configured to be molded separately and attached to the container body.

FIG. 1 shows an example in which a flexible cone-shaped container body 1 and a nozzle-shaped conduit 2 which are separately molded are attached. In this case, the container body is made of a flexible and sufficiently flexible material such as thin soft vinyl chloride resin or polyethylene resin.

A recess 3 is provided in the center of the container body so as to be parallel to the bottom of the container body. Now, after using this droplet extracting container to supply the desired amount of the desired droplets to the required locations, if left as it is, the retained liquid that has accumulated inside the nozzle-shaped conduit 2 will remain inside the conduit 2 as it is. It will be as it is.

However, after using the droplet extracting container, when the container main body is pressed between the thumb and the other four fingers and the concave portion provided in the container main body is pushed and expanded, the nozzle is removed. All the stagnant liquid in the tubular conduit can be completely re-stored in the container body.

Further, in the case of a cylindrical container body 4 made of a rigid and hard polyethylene resin or a hard vinyl chloride resin as shown in FIG. 2, an outer wall portion forming the container body 4 When the bellows-like body 6 is incorporated in a part of the container 5, the bellows-like body 6 is used in a closed state during the use of the droplet extracting container, and when the accumulated liquid in the nozzle-shaped conduit is used after use, In order to open the bellows-like body 6, when the container body is bent by applying a force so that the side where the bellows-like body 6 is installed extends, the bellows-like body 6 is opened and all the retained liquid in the nozzle-shaped conduit is completely discharged. Can be re-housed inside.

[0016]

[Effect of device]

 As described above, in the droplet extracting container according to the present invention, after a desired amount of droplets of a desired size are supplied to a desired location, all the retained liquid in the nozzle-like conduit is completely reconstituted in the container body. It is very economical and hygienic, without polluting the container itself or its surroundings.
