The deformation due to the pressing operation and the deformation due to the restoration to the original shape based on the elastic force of the elastic material,
A drip operating member made of an elastic material that reversibly increases or decreases the internal volume of the container body; and (d) defining the amount of deformation of the drip operating member due to the pressing operation, and the container due to deformation of the drip operating member. The contact means includes a volume change restricting means for restricting an amount of change in the internal volume of the main body, and further, a taper surface having a large diameter toward the tip is formed on the inner peripheral surface of the tip of the drip port. That is, the container for the lens action liquid drop was constructed.

作が極めて簡単となる。(Operation / Effect) In the contact lens operation liquid drop lower container according to the present invention, since the pressing deformation amount of the drip operating member is regulated to a constant by the volume change restricting means, the drip operating member is dropped when the working liquid is dripped. By pressing and deforming the container to its regulated position, the amount of pressing deformation during the pressing operation of the drip operating member is always constant, and the amount of change in the internal volume of the container body, and thus the action from the drip opening of the container body It is possible to keep the amount of liquid dropped almost always. Therefore, even when it is used as a container for a working solution, such as a cleaning solution for removing proteins adhering to contact lenses, where it is desirable to keep the usage amount substantially constant, the user adjusts the amount of the working solution taken out one by one. It is not necessary and the operation of taking out the working fluid becomes extremely simple.

である。Then, in such a dropping container, if the burrs as described above are formed at the tip of the dropping port of the container body, an excellent draining effect can be obtained at the time of dropping the working liquid, and the dripping of the working liquid is good. Therefore, it is possible to prevent the working fluid that has dropped along the outer surface of the container body from coming into contact with the user. Some working fluids are not desirable to directly touch the human body.

しているのである。That is, the pressing operation member 42 is fixed to the container body 10 in a state where the bulging portion 54 projects downward by a predetermined dimension from the inward flange portion 40 of the cylindrical member 38, and in the dripping container of the present embodiment. The pressure change of the bulging portion 54 of the pressing operation member 42 changes the internal volume of the container body 10 so that the working liquid contained in the container body 10 can be dropped from the dropping port 16. It has become. As is clear from this, here, the pressing operation member 42 constitutes the dropping operation member, and the bulging portion 54 of the pressing operation member 42 constitutes the pressing operation portion of the dropping operation member. Is there.
なお、押圧操作部材42の膨出部54は、押圧操作力が解

る。Further, here, the inward flange portion of the cylindrical member 38.
It is located on the tip surface of the small diameter portion 26 of the container body 10 that holds the outward flange portion 56 of the pressing operation member 42 between it and 40, and as shown in FIG. 2 and FIG. Sharp ridge
58 is provided, and by this ridge 58, the container body 10
The sealability of the lower opening of the is further improved.

している。Thus, the cylindrical member 38 has a tip end of the bulging portion 54 of the pressing operation member 42 so that the bulging portion 54 of the pressing operation member 42 is not unnecessarily pressed and deformed when the container is not used. It is made to project slightly below the tip of the portion 54, and its inner diameter is the width of the index finger of the user so that the bulging portion 54 of the pressing operation member 42 can be deformed by the user's index finger. The size is set to a size not less than about 15 mm, for example. And here, the inward flange portion 40
The inner surface of the cylindrical member 38 between the tip and the tip is a curved surface 60 recessed upward, and when the bulging portion 54 of the pressing operation member 42 is deformed by pressing, the index finger of the user touches the curved surface 60. The bulging portion 54 of the pressing operation member 42 is prevented from further deformation. That is, here, the inward flange portion 40 of the cylindrical member 38 forming the curved surface 60 serves as a volume change regulation unit that regulates the deformation amount of the pressing operation member 42, and thus the variation amount of the internal volume of the container body 10. It constitutes a rigid wall. Also, as is clear from the above description,
Here, the tip 61 of the cylindrical member 38 extending further downward from the inward flange 40 serves as a ridge that prevents unnecessary pressing deformation of the pressing operation portion of the drip operation member.

無駄な消費が無くなるといった利点があるのである。When using the working liquid contained in the container having such a structure, the cap member 30 is removed from the container body 10, the container body 10 is inverted, and the bulging portion 54 of the pressing operation member 42 is forefinger. Push it in until it can be pushed in. By doing so, the curved surface 60 (the inward flange portion) of the cylindrical member 38 is
The position where the user's index finger is pushed in is always constant by abutting against 40), and the amount of pressure deformation of the bulging portion 54 of the pressure operation member 42, and thus the amount of change in the internal volume of the container body 10, is always constant. Therefore, the amount of the working liquid dropped from the dropping port 16 of the container body 10 is always almost constant. Therefore, when used as a container for a working solution, such as a cleaning solution for removing proteins of contact lenses, where it is desirable to keep the usage amount substantially constant, the user adjusts the amount of the working solution taken out one by one. Therefore, the operation of taking out the working fluid becomes extremely simple. Further, even when it is used as a container for the working fluid without such a restriction on the usage amount, it is possible to accurately drop the required amount, and there is an advantage that wasteful consumption of the working fluid is eliminated.

るのである。Further, in the dropping container of the present example, as described above, the burrs portion 18 is provided at the tip end portion of the dropping port 16 so that the dripping at the time of dropping the working liquid is favorably prevented. Therefore, there is also an advantage that it is possible to favorably prevent the dripping action liquid from adhering to the human body.In addition, the swelling portion 54 of the pressing operation member 42 as the pressing operation portion of the drip operation member is inward. Since the cylindrical member 38 is surrounded by the distal end portion 61 and is prevented from being unnecessarily pressed and deformed, there is a problem that the working liquid is unnecessarily dropped due to an unnecessary pressing and deforming operation of the bulging portion 54. There is also an advantage that it can be avoided.
