A cylindrical portion extending from the peripheral edge of the through hole drilled in the center of the bottom wall of the recessed portion to the upper side of the top wall is erected, and the bottom wall of the recessed portion is formed in a taper shape that extends downward and the middle portion of the cylindrical portion. A cap body having a plurality of through holes formed therein, and a fitting cylinder vertically movably fitted to the outer peripheral upper part of the cylindrical portion of the member, and a peripheral wall vertically extending from the outer peripheral edge of the top wall vertically extending from the center of the rear surface. When the cap is lowered on the outer periphery of the upper portion of the peripheral wall of the cap, a downward step portion that fits on the upper edge of the outer peripheral wall of the recess is provided around the lower portion of the peripheral wall below the step portion. It describes a fixed-quantity shaking container that is reduced in diameter through a taper inwardly and hangs between both peripheral walls of the recess. That. In the fixed amount shaking container, with the cap raised, after the container body is inverted and measured,
Since the powder that has been erected upright and inverted again and weighed out to the outside of the container, the amount of shaking can be made constant.

[0003]

However, in the above-mentioned conventional fixed-quantity shaking container, since the through hole is always open, if the container is vibrated or tilted during transportation, the powder inside the container will be Granules (hereinafter, simply referred to as powder) may flow into the cap body. Therefore, in the first shaking operation after purchase, there is a problem that the unmeasured powder that has entered the cap body due to the above-described vibration is shaken out when the container body is inverted for the first time for weighing. In addition, if the container is accidentally tilted during storage after the start of use, the amount of measured powder stored in the cap body will increase or decrease, and the amount of shakeout will change.

The present invention provides a powder measuring container in which the amount of shaking does not change even if vibration is applied to the container during transportation, the container is tilted, or the container is tilted during storage after the start of use. The purpose is to

[0006]

1 to 3 show the essential parts of a powder measuring container 1 of the present invention. The powder measuring container is composed of a container body, a cap body, and a cap.
At least the cap body and the cap are molded from a synthetic resin material.

The container 2 has a mouth and neck 4 standing upright through a shoulder 3 from a bottomed body that stores powder or granules (hereinafter, simply referred to as powder). . Since a cap body described later is screwed into the mouth / neck portion, a screw thread is formed on the outer surface thereof.

The cap body 5 has a flange-shaped top wall 6 engaged with the upper end surface of the mouth / neck portion 4, and a first peripheral wall 7 screwed from the outer periphery of the top wall to the outer surface of the mouth / neck portion. A second peripheral wall 8 which is airtightly fitted to the inner surface of the mouth and neck from the inner peripheral edge of the top wall 6 is provided.
Each hang down from the lower end of the second peripheral wall to the inward flange 10
The third peripheral wall 11 is erected through the plurality of through holes 12 and a plurality of through holes 12 are formed in the middle portion of the third peripheral wall at substantially equal intervals. Hang down. The cap main body 5 having the above structure includes the second and third peripheral walls 8 and 11.
And a space partitioned by the inward flange 10 is formed, and this space is used as a storage chamber A, and the storage chamber stores the measured powder. In the illustrated example, the inward flange 10
Protrudes obliquely inward from the second peripheral wall 8 in order to efficiently guide the powder in the container body 2 to the inner space of the third peripheral wall.

The cap 13 has a fitting cylinder 14 which is fitted to the outer surface of the upper portion of the third peripheral wall 11 so that the upper cylinder can be moved up and down and which closes the through holes 12 with the lower cylinder. A stopper rod 18 having a wall 15 and having a locking ridge 17 on the outer surface of the lower end in a state of rotatably penetrating into the tapered tube 16 from the central portion of the top wall, and also the top wall. From the outer periphery, the lower outer surface is the second
A plug cylinder 20 that is airtightly and detachably fitted to the inner surface of the upper end of the peripheral wall 8.
Respectively, and a partition cylinder 22 is hung by a flange 21 projecting inwardly downward from the lower end of the stopper cylinder with a gap between both walls of the second and third peripheral walls 11. A space partitioned by the fitting cylinder 14, the top wall 15, the stopper cylinder 20, the flange 21, and the partition cylinder 22 is formed in the cap 13 having the structure, and the space is used as a measuring chamber B. In the illustrated example, the cap 13 is composed of two synthetic resin molded products divided at the upper part of the stopper cylinder 20.

The respective lengths of the fitting cylinder 14, the plug cylinder 20 and the partition cylinder 22 are the upper limit of the cap 13 shown in FIG. 2, that is, the position where the lower end of the tapered cylinder 16 contacts the locking projection 17 of the plug rod. When it is moved up to the upper edge of the through hole 12, the lower end of the fitting tube 14 is substantially above the upper edge of the through hole 12, the lower end of the stopper tube 20 is above the second peripheral wall 8, and the lower end of the partition tube 22 is the lower edge of the through hole 12. It is formed so as to be located below each. Reference numeral 23 indicates that when the cap 13 is pulled up with respect to the cap body 5, the stopper cylinder 20 causes the second peripheral wall 8 to move.
It is a spout formed by separating from. In the illustrated example, the upper cylindrical portion is screwed onto the outer surface of the upper portion of the third peripheral wall 11, and the cap 13 is rotated to raise or lower the cap with respect to the cap body 5. . In the illustrated example, the outer surfaces of the upper and lower ends of the top of the stopper tube 20 are chamfered,
The cap 13 is formed in a shape that is easy to grasp, so that the cap 13 can be easily rotated.

Incidentally, an annular projection as a locking projection 17 is attached to the outer surface of the lower end of the stopper rod 18, and the annular projection is engaged with the lower end of the tapered cylinder 16 of the fitting cylinder as shown in FIG. Although the cap 13 is prevented from coming off from the cap body 5 by stopping, the shape of the locking projection 17 may be a projection. Furthermore, as shown in the example, leaving the lower end of the stopper rod 18,
A similar effect can be obtained by forming an annular recess in the lower portion and making the inner diameter of the lower end face opening of the tapered cylinder 16 of the fitting cylinder substantially the same as the outer diameter of the annular recess.

In the powder measuring container 1 having the above structure, when the cap 13 shown in FIG. 1 is screwed down, the through hole 12 is closed by the fitting cylinder 14, so that the powder measuring container 1 is vibrated during transportation. The powder in the container body 2 does not flow out into the cap body 5 even if it is inclined. When the cap 13 is screwed up from this state, the through hole 12 and the spout 23 are opened.

When the powder measuring container 1 in the state shown in FIG. 2 is inverted, the powder in the container body 2 is guided by the lower surface of the tapered cylinder 16 and flows into the measuring chamber B through the through hole 12. The flow into the measuring chamber is stopped when the upper surface of the deposited powder is flush with the lower end of the through hole 12, so that the amount of powder flowing into the measuring chamber B is always constant. At this time, since the powder has not accumulated in the storage chamber A as described above, the powder is not discharged from the spout 23.

When the powder measuring container 1 is erected from the above state, the powder in the measuring cylinder B falls into the storage chamber A and accumulates. At this time, since the powder in the space inside the third peripheral wall 11 falls into the container body 2, the amount of powder deposited in the storage chamber A becomes constant. Thereafter, when the powder measuring container 1 is inverted again, the powder in the storage chamber A is shaken out of the powder measuring container 1 through the spout 23 as shown in FIG. At this time, a part of the powder in the storage chamber A may return to the measuring chamber B, but the amount of powder returning to the measuring chamber B and the amount of powder shaken out of the powder measuring container 1 are almost constant. Therefore, the amount of powder shaken out of the powder measuring container 1 becomes substantially constant. After that, when the powder measuring container 1 is erected, the powder in the measuring chamber B flows into the storage chamber A and the preparation for the next shaking is completed.

When the powder feeding is finished, the cap is
Screw 13 down. In this state, since the through hole 12 is closed, even if the powder measuring container 1 tilts or falls during storage, the powder container 1 is stored in the storage chamber A and from the storage chamber A in the storage chamber A. Since the powder does not flow into the storage chamber A, the amount of powder in the storage chamber A does not increase or decrease, and therefore, the next squeeze amount does not change.

[0016]

The powder measuring container 1 according to claim 1 has the above-described structure. When the cap 13 is lowered with respect to the cap body 5 to close the spout, the third peripheral wall of the cap body 5 is closed. Since the plurality of through holes 12 formed in the intermediate portion are provided so as to be closed by the fitting cylinder 14 of the cap 13, the powder in the container body 2 may be vibrated during transportation or the like, and the through holes 12 may cause the cap body 5 to pass through. Since it does not flow out into the container, the powder will not be shaken out of the container during the first shaking operation after purchase, that is, at the time of weighing, and thus the first shaking amount can be made more accurate. Even if the powder measuring container 1 tilts or falls during storage after the start of use, since the through hole 12 is closed, the amount of powder measured after the measurement stored in the cap body does not increase or decrease. Can be made more accurate.

Further, when the second peripheral wall 8 of the cap body is airtightly fitted to the inner surface of the mouth / neck portion 4 of the container body and the cap 13 is lowered to close the spout, the outer surface of the cap barrel 20 of the cap is
Since it is provided so as to be airtightly fitted to the inner surface of the upper end portion of the second peripheral wall 8 of the cap main body, invasion of moisture into the container body 2 is prevented, so that the powder inside the container body 2 can be prevented from solidifying. it can.

The powder measuring container 1 according to claim 2 has the effects according to claim 1, and the inner surface of the upper cylinder portion of the fitting cylinder is screwed to the outer surface of the upper portion of the third peripheral wall 11 of the cap body. When the cap 13 is moved up and down with respect to the cap body 5, it can be performed with a small force, and the cap can be closed more reliably.
