1 and 2, 1 is a container body, 2 is a receiving cylinder, 3
Is a cylinder member, 4 is a stopper member, and 5 is a plunger member.

The container body 1 is made of synthetic resin in which a threaded mouth-neck portion 7 is erected on the upper end of the body portion 6.

The receiving cylinder 2 is provided with a ball valve type suction valve 10 at a lower portion of a cylindrical portion 9 that hangs down from the mounting portion 8 attached to the mouth / neck portion 7 into the container body 1, and from the suction valve 10 to the inside of the container body 1. The suction pipe 11 is vertically installed at the bottom.

In the illustrated example, the mounting portion 8 allows the screw cylinder 8b hanging from the outer peripheral edge of the ring-shaped top plate 8a to be screwed onto the outer surface of the mouth / neck portion 7, and the fitting cylinder 8c hanging from the lower surface of the ring-shaped top plate 8a. It is watertightly fitted to the inner surface of the mouth / neck portion 7, and the guide tube 8d is erected upward from the upper surface of the ring-shaped top plate 8a. In addition, the cylindrical portion 9 has a large diameter cylindrical portion 9b with a thread above the stepped portion 9a with the annular groove 12.
And a small-diameter cylindrical portion 9c having a tapered portion below the stepped portion 9a and having the suction valve 10 and the suction pipe 11 respectively. At the bottom of the annular groove 12 is an outside air suction hole.
14 are formed in the circumferential direction. The mounting portion 8 and the tubular portion 9 are integrally molded using a synthetic resin material.

The cylinder member 3 detachably and watertightly fits a nozzle 17 hanging down from the central portion of the bottom wall 16 of the cylinder tubular portion 15 into the upper half of the tubular portion 9 and guides the cylinder tubular portion 15. It is made of a synthetic resin that is erected above the cylinder 8d.

In the illustrated example, the nozzle 17 is formed in a tapered shape and fitted into the tapered portion of the small diameter tubular portion 9c. Also, from the outer peripheral portion of the bottom wall 16 of the cylinder tubular portion 15 to the short tubular portion with a thread
18 is vertically provided, and the short tubular portion 18 is screwed into the large-diameter tubular portion 9b, and the lower end of the short tubular portion 18 is watertightly fitted into the annular groove 12 of the stepped portion 9a. Further, a first engaging protrusion 19 is provided around the upper edge of the cylinder wall of the cylinder cylinder portion 15.

The stopper member 4 is made of a synthetic resin in which a short tubular portion 21 which is hung from the lower surface of the ring-shaped top plate 20 having an inner diameter smaller than the inner diameter of the cylinder tubular portion 15 is fitted to the upper end portion of the cylinder tubular portion 15.

In the illustrated example, the upper surface of the second engaging projection 22 provided on the inner edge of the lower end of the short tubular portion 21 is engaged with the lower surface of the first engaging projection 19.

In the plunger member 5, the lower large outer diameter portion 24 of the plunger 23 is slidably brought into sliding contact with the inner surface of the cylinder tubular portion 15 while the upper small outer diameter portion 25 of the plunger 23 is ring-shaped top plate 20.
It is made of a synthetic resin which is vertically rotatable with respect to the cylinder member 3 and the stopper member 4 and which has a finger hook ring 26 attached to the upper surface of the upper small outer diameter portion 25 so as to vertically move therethrough. The cylinder member 3 and the stopper member 4 form a spout A.

In the illustrated example, the lower large outer diameter portion 24 and the upper small outer diameter portion 25 are formed separately. That is, in the lower large outer diameter portion 24, the elastic peripheral wall 24b having an arcuate cross section attached to the outer peripheral portion of the circular bottom plate 24a is slidably contacted with the inner surface of the cylinder tubular portion 15, and the bottom plate 24 is
a Fitting tube 24c is erected from the center of the upper surface. On the other hand, the upper small outer diameter portion 25 is formed by fitting the fitting cylinder 24c into the lower portion of the peripheral wall 25b which is vertically provided from the central portion of the lower surface of the top wall 25a with the finger hanging ring 26.

Further, a ratchet mechanism 27 is provided between the outer surface of the peripheral wall 25b and the inner peripheral surface of the ring-shaped top plate 20 of the stopper member 4, and the plunger member 5 with respect to the cylinder member 3 and the like.
It is designed to intermittently rotate forward at 90 ° intervals. This is because the reverse rotation of the plunger member 5 is prevented so that the plunger member 5 is integrated with the cylinder member 3 and the like in the reverse rotation direction. Therefore, the reverse rotation operation of the plunger member 5 causes the short cylinder portion of the cylinder member 3.
This is because it is possible to unscrew the 18 and the large outer diameter portion 9b of the receiving cylinder 2. In the figure, 27a is a groove constituting the ratchet mechanism 27, which is 90 ° in the circumferential direction of the inner peripheral surface of the ring-shaped top plate 20.
Four pieces are formed at intervals. Further, 27b is a protrusion that constitutes the same ratchet mechanism 27, and is 9 in the circumferential direction on the outer surface of the peripheral wall 25b.
Four vertical lines are installed at 0 ° intervals.

Then, the lower large outer diameter portion 24 of the plunger member 5 and the lower surface of the ring-shaped top plate 20 of the stopper member 4 are provided with first and second engaging protrusions 28, 29 for adjusting the plunger stroke, respectively. .

In the illustrated example, one engaging projection 28 is provided on the upper surface of the lower large outer diameter portion 24, and two engaging projections are provided on the lower surface of the ring-shaped top plate 20 at point symmetrical positions and at positions corresponding to the grooves 27a. 29,29 are attached.

Therefore, in this embodiment, the plunger member 5 is intermittently rotated forward at regular intervals of 90 ° with respect to the cylinder member 4 and the like, so that the plunger strokes are l ₁ (see FIG. 3) and l ₂
(See FIG. 4) and can be selected alternately. Further, as shown in the figure, it is preferable that the notch 30 for display exposure is formed on the outer peripheral portion of the top wall 25a while the capacitance display is provided on the upper surface of the ring-shaped top plate 20 at intervals of 90 °.

[Advantages of the Invention] As described above, according to the present invention, by extending the plunger member with respect to the cylinder member or the like, the liquid in the container is sucked up into the cylinder member, which simplifies the structure. Since the cost can be reduced and the suction pipe can be fixedly attached to the receiving cylinder, the position of the lower end of the suction pipe becomes unstable like in the conventional example, and the liquid that cannot be poured into the container body is unusable. Will never increase. Further, since the plunger member can be stretched by the finger ring, it is easy to use. In addition, since the plunger stroke can be changed and the pouring amount can be variably adjusted by a simple operation of rotating the plunger member with respect to the cylinder member or the like, it is very convenient to use.
