Description

[Detailed description of the invention] [Industrial application field] This invention makes it possible to take out an appropriate amount of a medicinal solution used for cosmetics such as lotion, beauty serum, medicine, office supplies, etc. contained in a container. Regarding the dropper.

[Conventional technology]

Conventionally, containers with a built-in dropper have been formed so that the length of the dropper is shorter than the depth of the container, making it extremely difficult to completely remove the liquid within the container. In order to prevent such drawbacks, a device is already known in which the hollow cylindrical body of the dropper is made longer than it reaches the inner bottom surface of the container, and is bent into an L-shape after reaching the inner bottom surface of the container.

[Problem that the invention attempts to solve]

However, in the case where the hollow cylinder is simply made longer, the hollow cylinder is molded from a flexible resin material, and in order to make it easier to bend, it is necessary to increase the outer diameter and wall thickness. I couldn't do it. Moreover, in this case, since the entire structure is made of a soft synthetic resin, there is a drawback that it is difficult for the bent object to return to its original shape. It should be noted that the hollow cylindrical body made of a soft synthetic resin cannot be attached to the lid body by fitting or the like, and it is difficult to attach it durablely without adhesion or the like.

[Means for solving problems]

The present invention has been improved in order to solve the above-mentioned drawbacks, and the hollow cylinder of the dropper is composed of a long cylinder made of a soft synthetic resin and a short cylinder made of a hard material. The present invention is characterized in that the upper part of the long tube is reinforced.

〔Example〕

The structure of the present invention will be described below with reference to the drawings showing one embodiment thereof. Reference numeral 1 denotes a lid body;
There is an elastic head 2 on the upper part of the body, and a hollow cylindrical body 3 on the lower part.
is fitted through the lower end of the elastic head 2, forming a dropper 4 as a whole. Reference numeral 5 denotes a container for storing liquids such as cosmetics and medicinal solutions, and after the hollow cylindrical body 3 is placed in the container 5, the lid 1 is screwed onto the container 5 and then sealed.

The hollow cylindrical body 3 consists of a long tube 6 with a small diameter made of a soft synthetic resin and a short tube 7 with a large diameter made of a hard material. Further, the long cylinder 6 with a small diameter is fitted into the short cylinder 7 with a large diameter with its lower part exposed, and the short cylinder 7 reinforces the upper part of the long cylinder 6. Regarding the lengths and proportions of the long cylinder 6 and short cylinder 7 in the hollow cylinder 3,
The length and thickness of the hollow cylinder 3, the flexibility of the long cylinder 6, the usability of the dropper, and other conditions may be taken into consideration and the selection may be made as appropriate. The long tube 6 is formed from a soft synthetic resin such as soft polyethylene or soft polyvinyl chloride.
Further, the short tube 7 is made of a hard material such as hard synthetic resin such as hard polyethylene or AS resin, glass, or metal. The material of the long tube 6 has hardness, transparency,
It may be selected appropriately depending on the application, taking into consideration moldability and economic efficiency. The hollow cylindrical body 3 may be configured by fitting together a long tube 6 and a short tube 7 that are formed separately, or the short tube 7 is formed first, and the long tube 6 is attached to the short tube 7.
It may also be configured to be insert molded.

Furthermore, the tip 8 of the long tube 6 may be tapered and formed thin in order to facilitate the suction of liquid. Further, the long tube 6 is configured to be longer than it reaches the inner bottom surface of the container, and after reaching the inner bottom surface, it is bent into an L-shape.

In addition, in the structure of the hollow cylinder 3, the fitting state of the long cylinder 6 and the short cylinder 7 may be reversed. That is, the short tube 7 with a small diameter is inserted into the inside of the long tube 6 with a large diameter formed from a soft synthetic resin.
It is also possible to adopt a structure in which the upper part of the long tube 6 is reinforced.

[Effect]

Since the present invention is constructed as described above, when using this, after opening the lid 1 of the dropper 4, press the elastic head 2 with your finger, and then release the pressing force. As the pressing force is released, the elastic head 2 restores its original form due to its elastic repulsive force, but at this time, the container 5 is
The liquid contained in the container is sucked out. Note that the amount of liquid to be sucked may be adjusted by adjusting the pressing force on the elastic head 2. Furthermore, after sucking the liquid, the dropper 4 is taken out from the container 5, the tip 8 is brought close to the target area, and the elastic head 2 is again
By pressing , the appropriate amount of liquid can be dripped.

Further, the hollow cylinder 3 is composed of a long cylinder 6 made of a soft synthetic resin and a short cylinder 7 made of a hard material that reinforces the long cylinder 6, and
The dropper 4 of the present invention can be used in the same way as a conventional dropper, since it is longer than the inner bottom of the container, and the lower part consists only of a bendable long tube 6. Moreover, the liquid in the container 5 can be completely taken out to the end.

That is, if the lid 1 of the dropper 4 is opened,
Since the long cylinder 6 of the hollow cylinder 3, which had been bent, expands due to its elastic force, the liquid remaining on the inner bottom surface and corners of the container 5 can be easily sucked out, as shown in FIG.

[Effect of idea]

As described in detail above, in the present invention, the hollow cylinder 3 of the dropper 4 has a long cylinder 6 having elastic force and a short hard cylinder 7.
When in use, the hollow cylindrical body 3 is long and expands quickly, and even the last drop left on the inner bottom surface or corner of the container 5 can be easily removed.
Moreover, it has the effect of being able to be suctioned quickly. Furthermore, the hollow cylinder 3 is configured such that the upper part of the long cylinder 6 made of soft synthetic resin is reinforced with the short cylinder 7 made of a hard material.
It does not have the drawback of being difficult to return to its original shape, which is the case when the entire hollow cylinder is made of soft synthetic resin. In addition, when fitting the hollow cylinder 3 to the elastic head 2 and the lid 1, the short cylinder 7 formed of a hard material can be used as the fitting part of the hollow cylinder 3. In terms of fitting strength and durability, there is no drawback such as detachment of the hollow cylinder which occurs when the entire hollow cylinder is made of soft synthetic resin.

In addition, since the hollow cylinder 3 is constituted by separate parts of the long cylinder 6 and the short cylinder 7, the short cylinder 7 can be made of any thickness, color, shape, wall thickness, and material.

Further, since the structure is simple and can be easily assembled, it is suitable for mass production, and therefore, it is possible to provide inexpensive products to consumers.
