Description

[Detailed description of the invention] The present invention relates to a dropper that makes it possible to take out liquids such as cosmetics and medicines stored in a container without leaving any residue. In a dropper constructed by fitting an elastic cap into the lower end of the dropper, a hollow ring body having a suction hole in a part of the outer circumferential wall at the lower end is attached to the tip of the hollow cylindrical body so as to be slidable up and down. This is related to the eye dropper that was featured.

Conventional droppers of this type have the disadvantage that the height of the dropper is slightly shorter than the depth of the bottle, so that the liquid inside the bottle cannot be completely removed. In order to improve this drawback, the hollow cylinder is made longer than necessary so that it bends into an L-shape after it touches the inner bottom surface of the bottle, or the inner bottom surface of the bottle is tapered. When the amount of liquid stored in the bottle becomes low, there is a method of collecting it at the lowest point and using a dropper. In addition, bottles with large outer diameters and wall thicknesses have the disadvantage of being difficult to bend, and the latter cannot be molded using the blow molding method commonly used for bottle molding. It had drawbacks such as not being able to be mass-produced at low cost.

The dropper according to the present invention relates to a completely new technology developed in view of the drawbacks of the conventional technology. To specifically explain one embodiment of the dropper according to the present invention with reference to the drawings, in FIG. An elastic spring 3 is fitted between the cap 2 and the hollow cylindrical body 1.
is installed. Further, a seat ring 4 is provided protruding from the inner circumferential wall at the tip of the hollow cylindrical body 1.

Next, reference numeral 5 denotes a hollow ring body that can be slidably inserted into the tip of the hollow cylindrical body 1, and a suction hole 6 is bored in the outer circumferential wall of the lower end, and the upper and lower ends of the outer circumferential wall and the Hollow ring bodies 5 are placed in close contact with the hollow cylindrical body 1 in the middle to prevent the hollow ring bodies 5 from moving inadvertently from the hollow cylindrical body 1 due to the pressure exerted when using the sucked stored liquid. and a first collar larger than the outer diameter of the seat ring 4 to lock onto the seat ring 4 of the hollow cylindrical body 1 and prevent the hollow ring body 5 from falling off from the hollow cylindrical body 1. 8 and a second collar 9 are provided in a protruding manner.

In the figure, 10 is a bottle container into which a dropper can be inserted, 11 is a lower lid that is screwed into the opening of the bottle container 10, 12 is an upper lid, 13 is an upper frame, and 14 is a cover tube for these.

As mentioned above, in the dropper according to the present invention, since the hollow ring body 5 is attached to the tip of the hollow cylinder body 1 so as to be able to slide vertically, variations in the height dimensions of the inner surfaces of the hollow cylinder body 1 and the bottle container 10 occur. Moko's hollow ring body 5
The lower end of the hollow ring body 5 is always in contact with the inner bottom surface of the bottle container 10 while moving up and down.
You can take out every last drop of the liquid stored inside.

In the above embodiment, the hollow ring body 5 is slidably attached inside the hollow cylindrical body 1, but when the inner diameter of the hollow ring body 5 is made larger than the outer diameter of the cylindrical body 1, this hollow ring body 5 can be attached to the outer peripheral surface of the cylindrical body 1 so as to be able to slide up and down, and in this case, the seat ring 4, the collars 7, 8, 9, etc. are naturally attached to the opposite positions from the above. It is.

Furthermore, it is possible to attach a brush, tip, spatula, etc. to the lower end of the hollow ring body 5, depending on the use of the dropper.

As mentioned above, in the dropper according to the present invention, a hollow ring body capable of sucking liquid together with the hollow cylinder body is attached to the lower end of the hollow cylinder body so as to be slidable up and down and always in contact with the inner bottom surface of the bottle container. So,
By sliding this hollow ring body, the entire length of the dropper can be freely adjusted. The liquid stored in the bottle can be taken out to the last drop through the hole.
Further, this hollow ring body has a simple structure, can be mass-produced at low cost, and can be easily and forcibly fitted onto the tip of the hollow cylinder body.

[Brief explanation of drawings]

FIG. 1 is a partially sectional explanatory view of a dropper according to the present invention. 1 is a hollow cylinder, 2 is a cap, 4 is a ring seat, 5 is a hollow ring, 6 is a hole, 7, 8, and 9 are collars, 10 is a bottle container, and 14 is a cover tube.
