Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dripping container that can obtain a precise dripping amount.

[Conventional technology]

BACKGROUND ART Conventionally, tools as shown in FIGS. 8a and 8b have been used as dropping tools capable of dripping and taking out liquids, particularly solutions such as chemicals, in a container. This dripping tool is made up of a pipette 80 made of glass, a rubber 81 for aspirating liquid by pressing with a finger, and a cap 82 for attaching the pipette 80 and rubber 81 to the opening of a glass container 83. It is something that has become familiar.

Furthermore, some of the dripping tools shown in FIG. 9 have a container 90 with an elongated opening 91 to function as a pipette, that is, the pipette and container are integrated. This type of device is made of a polymeric material (for example polyethylene) which exhibits elasticity so that the container 90 can be compressed.

[The problem that the idea aims to solve]

In the dripping tool shown in FIGS. 8a and 8b, a pipette 80 for dripping is removable from a container 83, and the container 83 is generally made of glass.
Since the liquid is sealed in a glass container, it can be stored for a long time.

However, when dripping, the cap 82 is removed from the container 83.
Especially when dropping a large amount, it is necessary to repeatedly press the rubber 81 and suck the liquid (solution) into the pipette 80, which is very troublesome. Furthermore, when the cap 82 is removed, the opening of the container 83 is exposed, making it easy for impurities such as dirt and dust to enter the solution. moreover,
Since the liquid in the container 83 is taken out by suction, when the liquid becomes low, it becomes difficult to suction the liquid remaining at the bottom of the container 83 with the pipette 80, making it difficult to take out all the liquid.

On the other hand, in the dripping tool shown in FIG. 9, the container 90 itself has the function of a pipette, so the dropping operation can be easily performed, and since the container 90 is turned upside down to drip, it is possible to take out the liquid without leaving much liquid behind. can.
The tool shown in FIG. 9 differs from the tool shown in FIG.
Since you have to press down to drip the liquid,
Container 90 cannot be made of glass, but is typically made primarily of polyethylene, as mentioned above. however,
Since the polyethylene container 90 itself is breathable, it is not suitable for long-term storage of solutions that are subject to change due to atmospheric oxygen, water vapor, etc., for example. In addition, with the tool shown in FIG. 9, if the container 90 is pressed too hard, the liquid will continuously come out, and more than a predetermined amount of liquid will sometimes be wasted.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a dropping container that allows easy dropping operations, allows all liquid to be taken out without leaving any liquid behind, and prevents excess liquid from flowing out beyond the required amount.

[Means to solve the problem]

The object comprises a container and a dripping device attached to an opening of the container for dripping liquid in the container, the dripping device communicating with the opening of the container and capable of being pressed with a finger. an elastic hollow member having a size, and a tip member connected to the hollow member and having a hollow smaller than the hollow of the hollow member,
This is achieved by a dripping container characterized in that the hollow of the hollow member and the hollow of the tip member are communicated through a pin hole.

In the dripping container of the present invention, by holding the dripping tool with the container upside down, that is, by pressing the elastic hollow member of the dripping tool with your finger, the liquid in the hollow member passes through the pin hole and into the tip member. It is extruded and drips from the tip member.

The elastic hollow member has a size that can be pressed with a finger, and its hollow space holds several drops of liquid. The hollow part of the tip member has a size just right to hold the amount of liquid for one drop, and the amount of the drop can be precisely adjusted by this and the pin hole.

The dripping device attached to the opening of the container, especially its elastic hollow member, is made of an elastic material that can be pressed with a finger. Elastic materials include natural rubber, synthetic rubber (styrene/butadiene rubber, polyurethane rubber, butadiene/acrylonitrile). rubber, polysulfide synthetic rubber, fluorocarbon rubber, silicone rubber, isobutylene, isoprene rubber, polybutadiene rubber, polychloroprene rubber, polyisoprene rubber, polyisobutylene rubber, chlorosulfonated polyethylene rubber, etc.), sheet-shaped polymer resins ( Examples include polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, polyvinyl fluoride, polyethylene terephthalate, polystyrene, polycarbonate, polyamide, ABS resin, phenolic resin, urea resin, epoxy resin, melamine resin, etc. Therefore, it is selected appropriately.

Although the tip member of the dropping tool does not need to exhibit elasticity, in view of manufacturing costs, it is preferable that it is made of the same material as the hollow member and is integrally molded with the hollow member. Further, the pin hole communicating the hollow member and the hollow part of the tip member has the function of precisely adjusting the amount of liquid introduced into the tip member, and there is no particular restriction on the size as long as it can do this.

The containers used in this invention may be made of glass, polymer materials (polyethylene, etc.), light-shielding or translucent, etc., depending on the content (liquid), volume, period of use, etc. Selected.

〔Example〕

Hereinafter, the dripping container of the present invention will be explained based on examples.

FIG. 1 shows an example. Dripping container 1 shown in the figure
The container 10, the dripping tool 20 that is attached to the opening of the container 10, the fitting 30 that fits into the opening 11 to seal and fix the dripping tool 20 to the opening 11, and the dripping tool 20 are protected and A removable cap 40 for plugging the dripping tool 20 is provided. The dripping container 1 shown here employs a so-called virgin cap system in which it can be determined whether the cap 40 has used (opened) the dripping container 1 or not. That is,
By pulling the separating means 41 provided on the cap 40, the cap 40 is separated from the remaining portion 42 and the main body 4.
After the bottle is opened, the main body 43 can be attached to and removed from the fixture 30, and it can be easily determined whether the bottle has been opened or not based on the presence or absence of the separation means 41.

In FIG. 2 showing the details of the dripper 20, the dripper 20 consists of an elastic hollow member 21 of a size that can be pressed with a finger, and a tip member 22 connected to the hollow member 21. In this embodiment, the hollow member 21 and the tip member 22 are integrally molded from the same elastic material. The hollow member 21 has a tapered shape, an annular support portion 23 is formed at the end, and a conical hollow 24 that serves as a liquid flow path. Tip member 2
2 is tubular and has a hollow 25 of smaller diameter than the hollow 24, which hollow 25 is of a suitable size to hold the volume of a single drop. Hollow member 21
and both hollows 24 and 25 of the tip member 22 are pin holes 2.
6, the liquid in the container 10 is communicated with the hollow 2
4. It can be taken out through the pin hole 26 and the hollow 25.

As is clear from FIG. 3, which shows a cross section of the dripping container 1 shown in FIG. This is done by firmly adhering to the leading edge of the opening 11 to prevent liquid from leaking from this area and to prevent the dripping tool 20 from coming off. Further, a protrusion 44 is formed on the main body 43 of the cap 40 as a plug to close the opening of the tip member 22, so that liquid does not leak.

This dripping container 1 has a virgin cap type lid, so when using it, first open the cap 40.
The separation means 41 of the two are separated. Then, as shown in FIG. 4, remove the main body 43 of the cap from the fixture 30, turn the dripping container 1 upside down, and use your fingers to press the elastic hollow member 21 of the dripping tool 20, like the suction rubber of a conventional pipette. When pinched and pressed, the liquid in the container 10 drips from the tip member 22. By adjusting the pressing force at this time, the number and amount of drops can be easily adjusted. Furthermore, even if too much force is applied, only a few drops will be dropped, and a large amount of liquid will not come out continuously. This is because there is only a few drops of liquid in the hollow 24 of the hollow member 21, and the synergistic effect of the pin hole 26 and the hollow 25 of the tip member 22 ensures that the liquid is dripped one drop at a time. Furthermore, since the dripping container 1 is placed upside down and dripping is performed, all of the liquid can be taken out without leaving any liquid behind.

After use, attach the main body 43 of the cap to the mounting bracket 3 again.
0, the opening of the dripping tool 20 is sealed by the protrusion 44 of the main body 43, so that liquid does not leak.

6 and 7 show another embodiment. The dripping container 1 shown above is a disposable one in that the fitting 30 that fixes the dripping tool 20 to the opening 11 of the container 10 cannot be easily removed.
The dripping container 1' shown here has an opening 51 of the container 50.
A threaded portion is formed inside the fitting 60 so as to be screwed together. In this case, since the fixture 60 can be removed, the liquid can be replenished.

The present invention is not limited to the embodiments described above, and various embodiments are possible. For example, a cap does not have to be a virgin cap;
It may be color coded to allow easy separation of different types of liquids. Alternatively, if the container is made of glass, it does not have air permeability like a polyethylene container, and the liquid can be stored for a long time.

[Effect of idea]

Since the dripping container of the present invention is configured as described above, it produces the effects described below.

The dripper attached to the opening of the container consists of an elastic hollow member and a tip member, the hollow member has a size that can be pressed with a finger, and the tip member has a hollow smaller than the hollow of the hollow member. Since both hollow parts of the hollow member and the tip member are connected through a pin hole, a precise amount of dripping can be obtained just by pressing the elastic hollow member, and there is no possibility that more than a predetermined amount of liquid will come out continuously at once. All the liquid in the container can be taken out without any problems, and the dropping operation is easy.
