落下は大きな損失となる。Detailed Description of the Invention [Prior Art] Liquid substances such as reagents, reagents, and medicines have been conventionally stored in containers made of glass, ceramics, plastics, etc., and collected as needed. In particular, since the liquid substance in the container is directly collected drop by drop, as shown in FIG.
A container in which the inner plug having a is attached to the liquid container 3 is used. In the container, the liquid material is filled through the outer container opening 4 by removing the inner stopper, and then the inner stopper is attached and the container is turned upside down as necessary, or the outer container is swung up or down. It was pressed and the liquid substance inside was collected. However, in the case of collecting each drop in the container, there is a drawback that the amount per drop is large and the breakage of the drops is poor, and in particular when the inner volume becomes small, not a single drop but multiple drops are continuously dropped. Accurate sampling is essential when it is necessary to collect a predetermined number of drops of a liquid substance and mix it with other substances to exert specific performance and physical properties, or to produce a medicinal effect with a predetermined number of drops. The continuous drop of many drops has been a big problem. Further, when the liquid material is expensive, a large number of continuous drops causes a great loss.

未だ完全解決までにはいたらなかった。In order to overcome the above-mentioned continuous drop of many drops, conventionally, improvements have been made from the viewpoint of breakage of drops between the inner plug 2 and the liquid substance. Specifically, the method of changing the shape of the tip portion of the inner plug 2 or reducing the diameter of the discharge port 1 has been taken, but in the first place, drop breakage is caused by the surface tension of the liquid substance itself and the tip of the liquid substance and the inner plug. It is closely related to the interfacial tension with the part, and there is a limit from the standpoint of preventing droplet breakage simply by changing the shape and diameter,
I couldn't reach a complete solution yet.

止器具を提供するものである。As a result of earnest studies on the above problems, the inventors of the present invention have found that the improvement of drop breakage alone cannot be a fundamental solution to prevent continuous drop of multiple drops, and the main cause of continuous drop of multiple drops is It was found that the body temperature transmitted from the holding finger warms the air layer in the container, and as a result, the air layer expands and pushes out the liquid substance therein. Based on the above findings, the present invention is a container-mounted droplet continuous type that prevents continuous drop of multiple drops by suppressing heat conduction as much as possible and expansion of the air layer to enable continuous drop collection. A fall prevention device is provided.

成される。Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a typical example of a device for continuously dropping liquid drops according to the present invention. As shown in the figure, the most preferred embodiment of the device for continuously dropping liquid drops of the present invention is one in which a band-shaped pressing plate is used as the pressing plate, and the pressing plate is configured as a ring-shaped closed ring. is there. In this aspect,
The pressing plate may be provided with, for example, a gripping part, but normally, the pressing plate alone is configured as a device for continuously dropping liquid drops.
本考案の最大の特徴は、押圧板の液体用容器に対面する

填された容器から該容器の外壁面を押圧することにより
内部の充填液を滴下採取する際に、指から容器内の空気
層への体温の伝熱を可及的に防止することができる。The greatest feature of the present invention is that a plurality of protrusions 5 are provided on the surface of the pressing plate facing the liquid container. Due to the presence of the protrusions 5, when the inside filling liquid is dropped and collected from the container filled with a liquid such as a reagent by pressing the outer wall surface of the container, an air layer in the container can be obtained. The heat transfer of body temperature can be prevented as much as possible.
第１図に示す液滴連続落下防止器具は通常第２図に示す

器具を介して液体用容器３を挟持して逆様にし、器具の
外側面より押圧すればよい。The droplet continuous drop prevention device shown in FIG. 1 is usually used by mounting the liquid droplet continuous drop prevention device on the liquid container 3 with their central axes aligned with each other, as shown in FIG. When collecting the drop of the filling liquid, touch the outer surface of the device for continuously dropping liquid drops of the present invention, that is, the surface that does not face the liquid container 3, and hold the liquid container 3 through the device to reverse it. And press from the outside of the device.
このようにすることにより、指の押圧力は液滴連続落下
防止器具を介して液体用容器３の外壁面に伝わり、該容
器壁面の一部が容器内側に変形して内部の充填液が滴下
採取される。By doing so, the pressing force of the finger is transmitted to the outer wall surface of the liquid container 3 through the droplet continuous drop prevention device, a part of the wall surface of the container is deformed to the inside of the container, and the filling liquid inside drops. Collected.
この際、液滴連続落下防止器具に施された突起状物の各
先端が容器外壁面に接触していることから、該突起状物
を介して体温の一部が容器に伝わるが、突起状物により
伝熱面積は小さく、かつ突起状物の存在しない中間部に
は空気層を有するので体温が容器本体へ伝わりにくく、
その結果容器内の空気層の膨張が抑えられ、液滴が連続
して多滴落下することが防止される。At this time, since each tip of the protrusions provided on the device for continuously dropping droplets is in contact with the outer wall surface of the container, part of the body temperature is transmitted to the container through the protrusions. Depending on the object, the heat transfer area is small, and since there is an air layer in the middle part where there is no protruding object, it is difficult to transfer the body temperature to the container body,
As a result, the expansion of the air layer in the container is suppressed, and multiple drops are continuously prevented from falling.

い。In this way, the protrusions were applied with the intention of transmitting the pressing force to the container and reducing the heat transfer amount of the body temperature as much as possible. Therefore, the shape and number of the protrusions are not particularly limited as long as they have such a function. Generally, for example, a columnar shape, a conical shape, a hemispherical shape or the like as shown in FIG. Normally, when the number of protrusions is too small, when pressed for collection, the inner surface of the part of the continuous drop prevention device that does not have protrusions is in direct contact with the container and It is not preferable because there is a risk that a considerable amount of body temperature will be transmitted from the body. Therefore, it is preferable that a large number of protrusions having substantially the same height are provided so as to be distributed substantially uniformly.
