Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an improvement of a container with a dropper.

[Conventional technology and its problems]

Containers with droppers are used as containers for storing and dispensing liquid cosmetics such as Essence.

However, in the conventional container with a dropper of this kind, as shown in FIG.
The lower end 20 of the dropper 203 is screwed into the dropper 203.
5 and the inner bottom surface 206 of the bottle. Therefore, there was a problem that the entire amount of the expensive liquid contained in the bottle 204 could not be sucked up and used, which was uneconomical.

As a countermeasure against this problem, various containers have been proposed in which a notch is provided at the bottom end of the dropper and the dropper is pressed against the inner bottom surface of the bottle by screwing the cap onto the bottle, but these containers require a large number of parts and are complex in structure. In some cases, the pressing force may change over time, or the urging position may be far from the tip of the dropper, making pressing uncertain.

[Problems to be solved]

This invention was devised to solve the problems of conventional containers with droppers as described above, and its purpose is to reliably absorb the entire amount of stored liquid with a simple structure with a small number of parts. Moreover, when the cap is removed from the bottle, the dropper naturally extends and the liquid enters the dropper, making it possible to take out the liquid immediately.Furthermore, the entire amount of stored liquid can be sucked out without having to screw in the cap screw each time. The object of the present invention is to provide a highly practical container of this kind that can be used for various purposes.

[Means for solving problems]

In order to achieve this object, the present invention includes a container body containing a liquid, a cap detachably attached to the mouth of the container body, a cap-shaped dropper head internally fixed to the cap, and this dropper head. A long dropper pipe that is loosely inserted into the center hole of the cap and has a notch at its lower end, and a bellows that is connected to surround the outer periphery of the middle part of the dropper pipe and whose other end is fixed to the cap. It has a structure that

[Effect]

When the cap is attached to the container body, the lower end of the dropper pipe comes into contact with the inner bottom surface of the container, and since the bellows contracts, the dropper pipe contacts the inner bottom surface of the container with a predetermined pressing force.

When the operating piece is pressed, the cap-shaped dropper head becomes negative pressure, and the internal solution is sucked into the dropper head through the notch. When the cap is removed from the container body, the bellows will extend and the dropper pipe will extend downward, allowing the solution to rise inside the dropper pipe. Therefore, the internal solution can be taken out immediately.

In addition, because of the bellows, the lower end of the dropper pipe can be kept in contact with the bottom of the container at all times, making it possible to dispense the entire amount of solution without having to screw the cap into the container body each time. It can be easily and reliably absorbed.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 3 show an embodiment of a container with a dropper according to the present invention, in which 1 is a container body made of a bottle or the like, and 2 is a female thread 20 corresponding to a male thread 10 formed at the mouth of the container body 1. In this embodiment, it is made up of an inner part body 2a and an outer part body 2b surrounding it, and a through hole 21 is formed in the top of the outer part body 2b.

A flange 22 projecting inward is integrally formed above the female threaded area of the inner part body 2a, and an annular projection 23 is provided in the middle of the inner flange 22.
A proximal end portion of a cap-shaped dropper head 3 made of soft plastic or the like is press-fitted and fixed between the annular projection 23 and the inner circumferential wall of the cap. A guide cylinder 25 that descends by a required length is integrally formed at the tip of the inner flange 22.

In this embodiment, the cap-shaped dropper head 3 has a protrusion 30 that bulges in the height direction, and the outer part body 2
It is elastically in contact with the inside of the operation piece 6 which is secured to the through hole 21 of b via a stepped portion.

Reference numeral 4 denotes a dropper pipe, which is made of transparent plastic or the like as a component independent of the cap-shaped dropper head 3. The dropper pipe 4 of the present invention is slidably inserted through the guide cylinder 25 of the cap 2, and the upper part 40 is located in the hollow part of the cap-shaped dropper head 3 when the cap 2 is attached to the container body 1. , the lower end opening 41 is made in an elongated shape so as to be in contact with the inner bottom surface 11 of the container body 1.

The dropper pipe 4 is integrally molded with an outer collar 42 that can come into contact with the inner flange 22 at the upper end, while the lower end opening 41 lacks a notch (including a groove) 43 that communicates with the side. It is set up.
The brim 42 is configured, if necessary, in such a shape that its upper portion comes into contact with the inner surface of the cap-shaped dropper head 3 when the cap 2 is closed as shown in the figure.

Reference numeral 5 denotes a bellows made of soft plastic material or the like, and the body portion 50 surrounds the middle portion of the dropper pipe 4 located below the guide tube 25.
and a straight cylindrical portion 51 beyond this main body portion 50, a thick annular portion 52 connected upward from the end of the main body portion 50, and a flange portion 53 following this,
The straight cylindrical portion 51 has a protruding peripheral portion 54 on the inside of the tip,
It is press-fitted and fixed to a platform-shaped ring portion 43 formed on the dropper pipe 4 and a recessed step portion 44 following the platform ring portion 43 .

Further, the annular portion 52 is press-fitted into the guide tube 25 of the cap 2 via the uneven portion, etc., and the flange portion 53 is adapted to abut against the mouth edge portion 12 of the container body 1.

FIG. 4 shows another embodiment of the present invention, in which the cap-shaped dropper head 3 is made in a dome shape, and a pressing part 61 that contacts the top of the cap-shaped dropper head 3 extends downward from the top wall of the operating piece 6. It is formed.

Note that the above is an example of the present invention, and the bellows 5 may be connected to the dropper pipe 4 and the cap 2 by a method such as high-frequency welding.

Since the present invention has the above-described configuration, when the container body 1 is filled with a desired liquid and the cap 2 is screwed into the container body 1, the lower end opening 41 of the dropper pipe 4 comes into contact with the inner bottom surface 11 of the container, and , since the bellows 5 contracts, the dropper pipe 4 is moved to the inner bottom surface 11 of the container.
The upper part 40 of the dropper pipe 4 extends into the cap-shaped dropper head 3 by the amount of contraction of the bellows 5.

In this cap-attached state, the flange portion 53 of the bellows 5 is strongly pressed against the mouth edge portion 12 of the container body 1, so that the bellows also acts as a good sealing material and can reliably prevent leakage of the internal solution.

Then, when the operation piece 6 is pressed, the cap-shaped dropper head 3 becomes negative pressure, so the internal solution is sucked into the dropper pipe 4 through the notch 43, and the cap 2
When the bellows 5 is rotated and removed from the container body 1, the bellows 5 extends as the cap 2 rises, and the dropper pipe 4 thereby extends downward, causing the solution inside to rise relatively inside the dropper pipe. Therefore, cap 2
By removing it, the internal solution can be poured out immediately.

Furthermore, since the dropper pipe 4 can be made sufficiently long, even if the female thread 20 of the cap 2 reaches a position where it completely separates from the male thread 10 of the container body 1, the lower end opening 41 of the dropper pipe 4 can be connected to the inner bottom surface of the container. 11, thereby making it possible to easily and reliably suck out the entire amount of the internal solution without having to screw the cap 2 into the container body 1 one by one.

Since the bellows 5 is connected to the outer periphery of the middle part in the length direction of the dropper pipe 4, it is possible to reliably apply an expanding and contracting force, and the upper part of the dropper pipe 4 is guided by the guide tube 25 of the inner flange 22. Therefore, even if the dropper pipe 4 is long, it will not fall down, and the collar 4 at the upper end of the dropper pipe 4 will not fall.
2 is brought into contact with the inner flange 22, so it will not be extended more than necessary.

Furthermore, when the flange 42 at the upper end of the dropper pipe 4 is configured to come into contact with the inner surface of the cap-shaped dropper head 3 when the cap 2 is closed, the operating piece 6 is actuated when the cap 2 is removed as shown in FIG. It is safe because when the cap 2 is closed, the operation piece 6 will not be pushed down even if an unexpected external force is applied to it. That is, the dropper pipe 4 can also function as a safety device.
