[0008]

When the container is turned upside down by closing the spout 9 with the lid 4, the solution in the container flows into the preliminary measuring chamber from the inflow port 22 and further into the main cylinder 8 through the water hole 12. Then, the air in the preliminary measuring chamber and the measuring chamber is exhausted from the air hole 20 into the container. When the liquid level of the internal solution in the measuring cylinder reaches the upper edge of the water passage hole 12, the inflow of the internal solution stops.

After that, when the container is erected, the inner solution flowing into the preliminary measuring chamber and the measuring chamber flows into the measuring cylinder 11, leaving only the inner solution collected below the water passage hole 12. Excess inner solution returns to the container through the inlet 22 and the air hole 20. This completes the weighing.

When the lid is opened and the spout 9 is opened, and the container is tilted while the hinge portion is on the upper side, the measured inner solution is poured out from the spout 9. At this time, the inlet 22
And the water hole 12 is located on the upper side, so that the measured inner solution does not return to the container through the inlet and the water hole.

When the container is tilted until the air hole 20 is positioned above the inlet 22 and the water hole 12 is positioned above the air hole 20, the liquid in the container is pre-measured through the inlet 22. After entering the chamber 24, the air in the pre-metering chamber is replaced with the liquid in the container through the air hole 20, and the air hole 20 is closed by the liquid entering the pre-metering, so that the liquid flows into the pre-metering chamber. Stop. Next, if the container is returned to the erect state from this state, the liquid in the preliminary measuring chamber 24 enters the measuring cylinder 11 through the water passage hole 12, and the excess liquid returns to the container body through the air hole 20. Thus, the re-measurement is completed, and the liquid to be measured can be poured out by tilting the front of the mouth and neck of the container body downward. As described above, the container for tilting the liquid is inclined such that the air hole 20 is positioned higher than the inlet 22 and the water hole 12 is positioned higher than the air hole. When the liquid enters the chamber 24 and the container is returned to the upright position, the liquid enters the measuring cylinder 11 and is re-measured, preparing for the next liquid ejection. The lid 4 is closed as it is. Therefore, the first time the container body is inverted,
It can also be performed by flowing the liquid only into the preliminary measuring chamber 24 by the above-mentioned container body inclination.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, reference numeral 50 designates a container body which stands up from the upper end of a torso via a shoulder, and a male screw 52 is attached to the outer surface of the mouth and neck.

A measuring member 1 is mounted on the mouth and neck. The measuring member is mounted on the upper end surface of the mouth and neck portion from the upper end of the mounting tube 6 screwed to the outer surface of the mouth and neck portion 51, and projects from the inner periphery of the inward flange top plate 7 protruding inward. 8, the upper half of the main cylinder portion is a large-diameter portion 10, and the lower half is a bottomed measuring cylinder 11 that hangs from the lower end of the large-diameter portion via an inward flange, and the upper end of the main cylinder portion And a water passage hole 12 is formed at the rear of the lower end of the large diameter portion, and a lid 4 is attached to the rear of the mounting cylinder 6 via the hinge 3. A stopper 17 is provided vertically from the lower surface of the top plate of the lid 4 so that the stopper is fitted to the inner surface of the pouring cylinder 16 in a watertight manner.

In the illustrated example, as shown in FIG.
A protrusion 15 is provided vertically on the upper front surface of the upper portion 11 and a protrusion 13 is provided around the outer periphery of the measuring cylinder portion where the lower end of the protrusion is located.

Reference numeral 5 denotes an auxiliary member for measuring, which is provided with a guide tube 19 standing upright from an upper end of a fitting tube portion 18 fitted and fixed to an upper outer surface of the measuring tube 11 via an inward flange. The outer periphery of the upper end of the tapered cylindrical portion is water-tightly pressed against the inner surface of the lower portion of the neck portion of the container body. A part of the rear of the tapered cylindrical portion is cut out to form a liquid inlet 22. At the front of the inward flange, an air hole 20 for both water passage is formed. A concave part 23 for fitting the convex part 15 is provided vertically on the inner surface of the front part of the fitting cylindrical part 18 described above, and the turning of the auxiliary member 5 with respect to the measuring cylinder 11 by the engagement of the concave part and the convex part. It is impossible to move. The concave and convex portions may be provided in reverse, or may be provided at other positions than the front portion. The container body 50, the measuring member 1, and the auxiliary member 5 are each formed of a synthetic resin material.

[0016]

The present invention has the above-described structure, and the number of members can be formed by only three members, the container body 50, the measuring member 1, and the auxiliary member 5.

The auxiliary member 5 raises a guide cylinder 19 from an upper end of a fitting cylinder 18 fitted and fixed to an upper outer surface of the measuring cylinder 11 via an outward flange, and expands the upper part upward and outward. Since the outer periphery of the upper end of the tapered tube portion 21 provided in this manner is pressed against the inner surface of the mouth and neck of the container body in a water-tight manner, the liquid inlet 22 can be formed only by partially notching the rear portion of the tapered tube portion 21 and the auxiliary member can be formed. Can be extremely simplified.

The press-contact position of the outer periphery of the upper end of the tapered tube portion 21 against the inner surface of the mouth-neck portion 51 may be the lower inner surface of the mouth-neck portion 51. Therefore, the length from the upper end of the fitting tube portion 18 to the upper end of the tapered tube portion 21 is reduced. That is, the length of the auxiliary member 5 can be significantly reduced as compared with the conventional one, and therefore, the auxiliary member molding material can be reduced.

Further, the preliminary measuring chamber 24 is provided with a mouth-neck portion 51 of the container body.
And the space surrounded by the top plate 7 and the large-diameter portion 10 of the measuring member and the auxiliary member 5, the outer diameter of the preliminary measuring chamber 24 is
In the case of the device disclosed in Japanese Unexamined Utility Model Publication No. 2-34459, the inner diameter of the mouth and neck 51 is equal to that of the top plate 7 and the large diameter portion 10 and the auxiliary member 5 is formed in the preliminary weighing chamber. Therefore, the entire length of the measuring member 1 can be shortened without changing the capacity.

The convex portion 15 provided on one of the outer surface of the upper portion of the measuring cylinder 11 and the inner surface of the fitting cylindrical portion 18 of the auxiliary member is fitted into the other concave portion 23 as described in the second aspect. It is possible to reliably maintain the respective positional relationships among the water passage hole 22, the water passage hole 12, and the air hole 20.
