DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with a dropper, and more particularly, to a container with a dropper that can suction and discharge a liquid content of the container with a simple mechanism and that can be manufactured at low cost.

[0002]

2. Description of the Related Art Hitherto, there have been many droppers intended for sucking / discharging a liquid contained in a container or the like.
Their basic structure is to press the elastic cap-shaped body portion of the dropper, use the restoring force of the elastic body portion to draw the contents of the container or the like into the dropper tube, and press again to draw the liquid. The contents in the dropper tube are discharged.

For example, in Japanese Utility Model Registration No. 2538844, two pushers of a central pusher and a plurality of flexible push pieces provided on a peripheral portion are provided on the lower surface of one push button. In the first stage of the pressing of the push button, the elastic cap-shaped body is pressed by the center pressing element, and in the second stage, the side portions of the elastic cap-shaped body are also pressed by a plurality of flexible pressing pieces. A dropper characterized by the above is disclosed.

[0004]

However, there is a problem that it is difficult to quantitatively suck up the content liquid of any of the commercially available syringes including the disclosed syringe. Of course, even if a conventional dropper is used, it is possible to quantitatively suck up the content liquid, but in that case, the mechanism needs to be complicated, and there has been a problem that the cost is greatly increased. Further, even in consideration of actual use, it is clear that a user who easily and easily sucks and discharges is easier to use than a device having a complicated mechanism.

[0005]

Therefore, there has been a demand for the development of a container with a dropper which can quantitatively suck and discharge the contents of the container with a simple mechanism and can be manufactured at low cost.

[0006]

Means for Solving the Problems The present invention has been obtained as a result of intensive studies to solve the above-mentioned problems, and has been locked to the container body, the outer lid and the mouth of the container body. In a container with a dropper including a dropper, the dropper is
A tubular body, an elastic cap that covers the upper opening of the tubular body, and an inner lid for locking the mouth of the container body, and a projection is provided on the upper inner surface of the outer lid; The elastic cap-shaped body of the dropper is pushed down by the projection when the outer lid is closed to the container body, and the elastic cap-shaped body is restored when the outer lid is opened from the container body. It is a container with a dropper.

Numeral 11 denotes a screw portion on the inner surface of the outer lid, and 12 denotes a screw portion on the side surface of the container.

In this embodiment, the projection 4 is provided inside the upper surface of the outer lid 3, and the inner screw portion 11 is provided inside the side surface of the outer lid. Also, a container side screw portion 12 is provided on the upper side surface of the container body 2, and the outer lid 3 can be closed to the container body 2 by screwing these screw portions. The material, size, and shape of the outer lid 3 and the container 2 are not particularly limited, but the material of the container 2 is glass or various plastics, and the material of the outer lid 3 is various plastics or metals. Are preferred.

[0010] As shown in FIG.
It is composed of an elastic cap 6, an inner lid 7 and a tube 8.
Among them, the elastic cap-shaped body 6 is formed in a substantially spherical shape by an elastic film, and the inside thereof forms an air reservoir. The elastic cap 6 covers the upper opening 9 of the tube 8 whose lower end is tapered. The elastic cap 6 and the tube 8
The inner lid 7 is attached so as to firmly couple the dropper 5 and the inner lid 7 is inserted into the mouth of the container body 2 to lock the dropper 5 itself.

As the material of the elastic cap-like body 6, various rubbers such as natural rubber, synthetic rubber, special rubber and the like, and those having moderate strength and elasticity such as EVA and elastomer are preferable. Is preferably made of glass, plastic or the like, and furthermore, plastic as the inner lid. In some cases, plastic having a certain degree of elasticity is used, and the elastic cap 6, the inner lid 7 and the tube 8 are integrated. It can also be formed. The thickness of the elastic film forming the elastic cap 6 varies depending on the size of the elastic cap and the restoring performance, but is usually about 0.2 to 2.5 m.
m is preferable.

The container 1 with a dropper of the present invention can quantitatively suck and discharge the liquid in the container 2 by the following mechanism.

First, when the outer lid 3 is closed with respect to the container body 2, the projections 4 provided on the upper inner surface of the outer lid 3 are also lowered, and as shown in FIG. The elastic cap-like body 6 of the dropper 5 locked on the part is pressed. By this pressing, air is pushed out from the air reservoir formed by the cap-shaped elastic body 6, air is also pushed out from the inside of the tube 8, air is discharged from the tube lower hole 10, and liquid is discharged from the tube lower hole 10. Becomes a state in which suction is possible. Here, the shape of the tube body 8 is not particularly limited, but a shape in which the lower end is thinner is preferable in terms of function.

Next, as the outer lid 3 is opened, the elastic cap-shaped body 6 returns to its original shape by its restoring force, and sucks the air in the tube 8 as shown in FIG. The liquid in the container 2 is sucked into the tube 8 by the suction force.

Since the dropper 5 is locked at the mouth of the container 2 by the inner lid 7, its position does not change during the closing and opening of the outer lid 3. Therefore, the amount of movement of the protrusion 4 with respect to the elastic cap 6 during the closing process of the outer lid 3 is constant, and the amount of deformation of the elastic cap 6 is also the same. As a result, the elastic cap 6 is discharged from the elastic cap 6 The air volume also becomes constant.
On the other hand, when the outer lid 3 is opened, the elastic cap-shaped body 6 returns to the same shape as the original shape due to the restoring force, whereby the liquid in the container body 2 can be sucked into the tube body 8 and held there. . The deformation of the elastic cap-shaped body 6 during the closing and opening processes of the outer lid 3 is always the same, and the amount of air suction, and thus the amount of solution sucked and held in the container body 2 by the tube 8 are also constant. By such a mechanism, in the container 1 with a dropper of the present invention, quantitative opening and closing of the outer lid 3 enables quantitative suction and holding of the solution.

Since the solution in the container body 2 is quantitatively sucked and held by the above-described mechanism, it is important that the elastic cap-shaped body 6 is always deformed into a constant shape, and it is not possible to twist the cap. If a natural deformation occurs, the purpose of quantitatively inhaling and holding the solution cannot be achieved. For this reason, when a mechanism for pushing down the outer lid 3 by rotating motion as in the above embodiment is employed, the projection 4 provided on the inner surface of the outer lid 3 is provided at the center of the inner surface, and the elastic cap-shaped body 6 is provided. It is also desirable that the tip portion in contact with is also round. It is also preferable that the diameter of the tip of the protrusion is not more than ４ of the diameter of the elastic cap-shaped body 6.

The size (length) of the projection 4, the size of the elastic cap 6, the type of the material, or the type thereof depends on the type and viscosity of the liquid in the container 2 or the amount to be sucked. It goes without saying that the thickness can be adjusted appropriately.

FIG. 4 is a cross-sectional view of a container with a dropper according to another embodiment of the present invention. The left half shows a state where the outer lid is closed, and the right half shows a state where the outer lid is opened. In the drawing, 13 is a threaded portion on the inner surface of the inner lid, 14 is a fitting portion on the outer surface of the inner lid, 1
Reference numeral 5 denotes an outer lid inner surface fitting portion, and the other portions are the same as those described above.

In the container 1 with a dropper of this embodiment, the inner lid 7 of the dropper 5 is shaped to cover the mouth of the container 2, and an inner lid inner surface thread portion 13 is provided on the inner side surface of the inner lid. This screw and the container side screw portion 16 for the inner lid on the outer surface of the container body
And can be screwed. Also, on the outer surface of the inner lid 7,
An inner lid outer surface fitting portion 14 is provided, and can be fitted to an outer lid inner surface fitting portion 15 provided on the inner surface of the outer lid 3.

In the container 1 with a dropper of this embodiment, the inner cap 7 is closed, and then the outer cover 3 is pushed down to press the elastic cap 6 of the dropper 5 locked at the mouth of the container 2. . And in this thing, since the outer lid 3 is not pushed down by rotation, the degree of freedom of the shape of the projection 4 is high. In addition, since the inner lid 7 is firmly locked to the mouth of the container body 2, there is an advantage that the solution inside hardly leaks even if it is accidentally knocked down.

FIG. 5 is a drawing showing a cross section of a container with a dropper according to another embodiment of the present invention. As in FIG. 4, the left half shows a state where the outer lid is closed, and the right half shows a state where the outer lid is opened. Is shown. Also, in the drawing, reference numeral 16 denotes a screw portion on the side surface of the container for the inner lid,
Otherwise, it is the same as above.

In the container 1 with a dropper of this embodiment, the inner lid 7 of the dropper 5 is shaped so as to cover the mouth of the container body 2, and the inner side of the inner lid is provided on the inner side surface of the inner lid as in FIG. An inner screw portion 13 is provided, and the screw can be screwed to the inner cover container side screw portion 16 on the outer surface of the container body. FIG.
The outer lid is screwed by the inner lid inner surface thread portion 11 and the container side thread portion 12 in the same manner as shown in FIG.

In the container 1 with a dropper of this embodiment, the inner lid 7 and the outer lid 3 are screwed, so that these lids are more securely closed, so that the inner solution does not leak even if it is accidentally dropped. Has advantages.

Thus, by using the container 1 with the dropper of the present invention, the solution in the container body 2 can be quantitatively sucked. The sucked solution is pushed by pressing the elastic cap-like body 6 with a finger. It can be easily discharged.

[0025]

In the container with a dropper of the present invention, the dropper is locked and fixed to the mouth of the container so that the outer lid provided with the projection is closed, and the elastic cap of the dropper is always the same. This is based on the knowledge that the pressing can be performed with the deformation amount. And, naturally, the liquid can be quantitatively sucked and discharged only by opening and closing the outer lid of the container body.
Anyone can easily take out the liquid quantitatively. Further, the above operation can be achieved only by the projection provided on the inner side of the outer lid and the inner lid provided on the dropper, so that the structure is simple and more advantageous than the conventional quantitative container.

[0026]

The container with a dropper of the present invention is capable of quantitatively sucking and discharging the liquid in the container by a simple operation of opening and closing the outer lid.

Accordingly, containers used in fields where high precision is not required but a quantitative solution is required, such as cosmetic containers, simple analysis reagent containers, liquid seasoning containers, and home gardening It can be used as an agricultural chemical container, a stationery container and the like.
