Description

[Detailed description of the invention] In this invention, a pipette is detachably attached to a container body containing a liquid, and when a cap is attached to the container body, the liquid enters the pipette, and when the cap is removed, the pipette containing the liquid is released. can be taken out,
This invention relates to a liquid metering pipette container in which the liquid in the pipette can be made to flow out by pressing a push rod on the head of the pipette.

The present invention will be described in detail with reference to the embodiments shown below. Reference numeral 1 denotes a container body containing a liquid, and the inner bottom 2 of the container body is formed into a narrow bottom shape so that the liquid is concentrated therein. Reference numeral 3 denotes a pipette, and a quantitative meter part 4 is integrally provided at the lower end of the pipette so as to be accommodated in the inner bottom part 2. Reference numeral 5 denotes a support provided at the upper end of the pipette 3 in order to detachably attach the pipette 3 to the mouth of the container body 1. Pipette 3 on support 5
A valve hole 6 is provided in communication with the valve hole 6.
An air valve 7 is provided therein so as to be movable up and down. The air valve 7 is integrally provided with a thin valve shaft 8 in the upper part thereof through a tapered surface 7a, and the valve shaft 8 is supported in a bearing hole 9 provided in the support body 5 so as to be loosely movable up and down. . A tapered sealing wall 10 facing the tapered surface 7a of the air valve 7 is provided between the valve hole 6 and the bearing hole 9 of the support body 5, and as shown in FIG. When the air valves 7a come into contact with each other, the ventilation holes 7b, which are provided through the upper and lower sides of the air valve 7, connect with the sealing wall 10 and the tapered surface 7.
The structure is such that it is sealed by abutting with a.
A through hole 11 is provided in communication with the upper part of the bearing hole 9 of the support body 5, and the valve shaft 8 projects above the support body 5 through the through hole 11. A pusher rod 12 is integrally provided on the protruding portion of the valve stem 8, and the lower part of the pusher rod 12 is inserted into the through hole 11, and between the lower end of the pusher rod 12 and the bottom of the through hole 11. includes a spring elastic member 1 biased with expansion elasticity;
3 is provided. This spring elastic member 13 plays the role of constantly pressing the air valve 7 against the sealing wall 10 via the push rod 12 and the valve shaft 8 to close it. Further, 14 is a cap attached to the neck of the container body 1, and as shown in FIG.
When the air valve 7 is attached, the push rod 12 is pushed downward against the spring elasticity of the spring elastic member 13, and the air valve 7 is opened.

To explain how the product of the present invention is used according to an embodiment having the above-mentioned configuration, as shown in the first figure, when the cap 14 is attached to the container body 1,
The pushing rod 12 is pushed down against the spring elasticity of the spring elastic member 13, the air valve 7 is lowered from the sealing wall 10, and the upper end of the pipette 3 has the valve hole 6, the ventilation hole 7b, the bearing hole 9, Through hole 11 and cap 1
Pipette 3 communicates with the outside via pipette 4.
The liquid contained in the container body 1 flows into the metering unit 4 from the inner bottom 2. When the cap 14 is removed from the container body 1, the push rod 12 is pushed upward by the spring elastic member 13, and the tapered surface 7 at the upper end of the air valve 7
a is tightly closed to the sealing wall 10 of the support 5, the upper end of the pipette 3 is sealed, and even if the pipette 3 is removed from the container body 1 by holding the support 5, the pipette 3 The liquid inside will not flow out. Next, when the pipette 3 is moved to a predetermined location and the push rod 12 is pushed downward as shown in the third figure, the air valve 7 becomes vented as in the case of FIG. This allows the liquid inside to flow out. Then, by returning the pipette 3 to the container body 1 again and attaching the cap 14, the state shown in FIG. 1 is achieved, and the pipette 3 can be filled with liquid.

As described above, according to the liquid metering pipette container according to the present invention, when the pipette is inserted into the container body and the cap is attached, the liquid can automatically flow into the pipette, and when the cap is removed, The upper end of the pipette can be automatically sealed, and by taking the pipette out to an arbitrary location and pushing in the pusher rod that protrudes from the support at the upper end of the pipette, the liquid inside the pipette can flow out. This has many practical advantages, such as being able to immediately discharge a measured amount of liquid from the pipette by removing the cap from the container body.
