The container part 2 is formed of the hack member 4 and the container body 6 in this embodiment.
The hook member 4 is formed by raising the fitting cylinder portion 4b from the outer peripheral portion of the horizontal plate-like bottom plate 4a.
The container body 6 erects the body part 10 from the outer peripheral part of the bowl-shaped bottom part 8 and erects the mouth-and-neck part 12 from the upper end of the body part 10 through the shoulder. A lower portion of the body portion 10 is formed in a small outer diameter portion 10a, and the fitting cylinder portion 4b is fitted on the outer surface of the small outer diameter portion so that the container portion 2 can be made independent. . However, these structures can be changed as appropriate. For example, the bottom portion 8 may be formed flat and the hook member may be omitted.

  As shown in FIG. 1, the dropper portion 20 is formed of a tubular body 22, an operation tube 40, and a pressing member 60.

  In the present embodiment, the tubular body 22 is formed by a dropper tube 24 and a piston cylinder 30 as shown in FIG.

The dropper tube 24 has an outward flange 28 attached to the outer surface of the intermediate portion of the tube wall 26, and a packing P is attached to the lower surface of the outward flange 28.
The dropper tube 24 has an outward flange 28 placed on the mouth / neck portion 12 through the packing P, and hangs down into the container body 6 in the lower half 26a of the tube wall. The half part 26b protrudes upward. Further, as shown in FIG. 2, a locking rib 27 for retaining a piston cylinder, which will be described later, is provided on the outer surface of the upper half 26b of the tube wall.

The piston cylinder 30 extends upward from the pipe wall upper half 26b.
The piston cylinder 30 of the present embodiment is provided with an intermediate part 30b projecting inward and outward from the upper end part of the base cylinder part 30a. The diameter-expanding cylindrical part 30c protrudes upward from the outer periphery of the intermediate part 30b. The folded tube portion 34 is suspended from the inner periphery. An annular seal portion 32 is formed on the outer surface of the enlarged diameter cylindrical portion 30c (the upper end portion of the outer surface in the illustrated example).
The inner surface of the base tube portion 30 a is fitted into the upper half 26 b of the pipe wall of the dropper tube 24, and the lower end of the base tube portion 30 a is in contact with the upper surface of the outward flange 28. At least one (preferably a plurality of) vertical ribs 33 are provided vertically on the outer surface of the upper half portion of the base tube portion 30a intermittently in the circumferential direction.
In the example of illustration, it forms so that the outer surface of these vertical ribs 33 and the outer surface of the enlarged diameter cylinder part 30c may become flush.
The folded tube portion 34 is suspended along the inner surface of the upper end portion of the dropper tube 24, and the upper end portion is formed so as to be sandwiched between the folded tube portion 34 and the base tube portion 30a.
The upper surface of the intermediate portion inside the enlarged diameter cylindrical portion 30 c is formed flat as a spring receiving portion 36.

In the tubular body 22 of the present embodiment, the lower locking surface r1 that is the upper surface of the outward flange 28 and the upper locking surface r2 that is the lower surface of the plurality of vertical ribs 33 face each other below the intermediate portion 30b. ing. The space between the lower locking surface and each upper locking surface has a function of restricting the movement of the engaging protrusion 46 that is loosely fitted in this space. This is referred to as a recess R.
The structure of the engaging recess R can be changed as appropriate as long as it fulfills the above functions. For example, instead of the space between the vertical rib and the outward flange, it may be an annular recess.

  In the present embodiment, the operation cylinder 40 is formed of an inner cylinder 42 and an outer cylinder 48 that are non-rotatably fitted to each other as shown in FIG.

As shown in FIG. 2, the inner cylinder 42 is screwed into the outer surface of the mouth-and-neck portion 12 with the lower portion of the cylindrical wall 43 as a screw cylindrical portion 43a having a screw portion 44 on the inner surface, and the upper portion of the cylindrical wall 43 is The upper portion of the tubular body 22 is an encircling cylinder portion 43b surrounding a certain gap g.
From the intermediate part of the cylindrical wall 43, an engaging convex part 46 having a certain thickness in the vertical direction protrudes inward. As shown in FIG. 2, the engaging convex portion 46 is loosely fitted into the engaging concave portion R with a certain width a between the upper engaging surface r <b> 2. The function of the engagement convex portion 46 is that when the inner cylinder 42 is screwed off from the mouth-and-neck portion 12, the lower limit position (position in contact with the lower engagement surface r1) in the engagement recess R is changed to the upper limit position (upper engagement). After moving to a position in contact with the surface r2, the tubular body 22 is pulled up via the upper locking surface r2. As long as this function is exhibited, the engagement protrusion 46 may have any structure. In the illustrated example, the engaging convex portion 46 is formed as an inward flange protruding from the inner cylinder 42.
Further, in the present embodiment, the engagement concave portion R is formed in the tubular body 22 and the engagement convex portion 46 is formed in the inner cylinder 42, but conversely, the engagement convex portion is formed in the tubular body 22. And you may form an engagement recessed part in the inner cylinder 42, respectively.

The outer cylinder 48 covers the entire inner cylinder 42 and is fitted to the inner cylinder 42 so as to be unrotatable by a rotation retaining means T. Further, an inward flange 50 projects from the upper end of the outer cylinder 48, and a claw portion 50a is attached to the inner periphery of the lower surface of the inward flange 50.
In the illustrated example, the swiveling means T is formed by a swiveling protrusion that is vertically provided on the inner surface of the outer cylinder 48 and a vertical groove that is vertically provided on the outer surface of the inner cylinder 42 and fits with the swiveling protrusion. ing.

The pressing member 60 integrally suspends the cylinder cylinder 64 from the outer peripheral portion of the top wall 62 which is a push button.
The cylinder cylinder 64 enters the gap g between the tubular body 22 and the operation cylinder 40 through the flange hole of the inward flange 50.
The illustrated cylinder cylinder 64 hangs a large-diameter lower half cylinder portion 64c from a lower end of a small-diameter upper half cylinder portion 64a via an outward flange-like wall portion 64b. At the lower end of the lower half cylinder portion 64c, a guide collar portion 66 that comes into sliding contact with the inner surface of the operation cylinder 40 is attached.
An extension wall portion 68 is suspended from the lower end of the upper half cylinder portion 64a. The lower end of the extended wall portion 68 is in contact with the upper end of the enlarged diameter cylindrical portion 30c. This prevents the pressing member 60 from descending below the position (lower limit position) shown in FIG.
The lower half cylinder part 64c is preferably provided so that the lower end of the lower half cylinder part 64c is higher than the lower end of the vertical rib 33 when the pressing member 60 is in the lower limit position. This is to prevent the movement of the engaging projection 46 from being disturbed.
Further, a claw portion 50a of the outer cylinder 48 is disposed on the outer surface of the flange-shaped wall portion 64b so as to be able to be locked, thereby forming stopper means S for preventing the pressing member 60 from being pulled out.
An annular seal portion 32 of the enlarged diameter cylindrical portion 30c is slidably contacted in the lower half cylindrical portion 64c.
In the present embodiment, since the sealing portion of the tubular body 22 with respect to the pressing member 60 is only one portion of the annular seal portion 32, the number of steps in terms of quality control of sealing performance as compared with the prior art having two sealing portions is reduced. Can be omitted.
The piston cylinder 30, the cylinder cylinder 64, and the top wall 62 define a measuring chamber C, and the volume of the measuring chamber changes as the cylinder cylinder 64 moves back and forth with respect to the piston cylinder 30.
A spring 70 is interposed between the lower surface of the top wall 62 and the spring receiving portion 36.
However, these structures can be changed as appropriate.

In the above configuration, in the state shown in FIG. 1, the lower end portion of the cylinder cylinder 64 is locked to the upper end portion of the diameter-expanded cylinder portion 30 c so that the pressing member 60 cannot be pushed down.
When using the quantitative dropper container of the present application, the operation tube 40 is rotated from the state shown in FIG. As a result, the engaging projection 46 moves from the lower limit position shown in FIG. 1 to the upper limit position shown in FIG. During this time, the pressing member 60 also rises according to the operation cylinder 40 due to the elastic restoring force of the spring 70, so that the pressing member 60 can be pushed down.
At the same time, the inside of the measuring chamber C is reduced to a negative pressure, and a certain amount of liquid is sucked into the dropper tube 24. This allows automatic weighing.
When the operation tube 40 is further rotated, the operation tube 40 is screwed up with respect to the mouth-and-neck portion 12, so that the engagement convex portion 46 of the operation tube 40 comes into contact with the upper locking surface r2 of the engagement concave portion R and is pulled up. Therefore, the dropper part 20 is separated from the container part 2 as shown in FIG.
Next, as shown in FIG. 5, the top wall 62 of the pressing member 60 may be pushed in to discharge the liquid in the dropper tube 24. Since the entire pressing member 60 is pushed in against the elastic force of the spring 70, a highly viscous liquid can be discharged at an appropriate momentum as compared with the conventional technique of pressing the dome-shaped elastic pressing portion.
