DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 6 show a constant volume dispensing container 1 of the present invention. The constant-rate dispensing container includes a container body and a measuring tap, and at least the latter measuring tap is integrally formed of a synthetic resin material.

[0007] The container body 2 has a bottomed body 3 for storing powder or granules (hereinafter simply referred to as powder).
Thus, the mouth and neck portion 7 having the small outer diameter portion 6 with the upper end portion facing upward through the shoulder 5 is erected through the shoulder portion 4. Since a cap is screwed into the mouth and neck, a screw is formed on the outer surface thereof. In the present embodiment, as shown in FIG. 1, since the finger hook of the measuring tap is projected outward of the mouth and neck 7, the small outer diameter portion 6 is formed at the upper end of the mouth and neck 7. However, the small outer diameter portion 6 may be omitted when the mouth and neck portion 7 is formed to be thick, and when the finger hanging piece is not projected outside the mouth and neck portion 7.

The measuring tap 10 comprises a fixed cylinder and a rotating member,
The mouth and neck 7 is fitted to the inner surface.

The fixed cylinder 11 hangs down a fitting cylinder 13 fitted on the inner surface of the small outer diameter portion 6 from the inner peripheral edge of the flange-shaped top wall 12 placed on the upper end surface of the small outer diameter portion 6. An upper small-diameter tapered cylinder 15 is erected from the lower end of the fitting cylinder via an inward flange 14. The tapered cylinder is used as a pouring cylinder when an arbitrary amount of powder is shaken, and an opening at an upper end surface thereof serves as a pouring hole 16. In the illustrated example, since the fitting tube 13 is fitted to the inner surface of the small outer diameter portion 6, a gap is formed between the lower portion of the fixed tube 11 and the mouth and neck portion 7. The length of the portion 6 is formed to be the same length as the fitting tube 13, or the inner surface of the mouth and neck portion 7 where the mouth and neck portion 7 is thick and the small outer diameter portion 6 is omitted as described above, The fitting cylinder 13 may be fitted.

The rotating member 20 has a top plate 21 mounted on the upper surface of the flange-shaped top wall 12 to close the upper surface of the fixed cylinder 11, and is attached to and detached from the outer peripheral surface of the top plate to the upper inner surface of the fitting cylinder 13. The locking cylinder 22 fitted freely and the top plate 21 above the tapered cylinder 15
From the partial lower surface, the measuring cylinder 23 with the upper end of the tapered cylinder 15 loosely inserted into the lower part is hung down, and the locking cylinder 22 is
As shown in FIG. 2, a plurality of small connecting portions 24 are left at substantially equal intervals in a top plate portion between the container and the measuring cylinder 23, and a stored material discharging hole 25 is formed.

In the illustrated example, the measuring cylinder 23 is hung from the lower surface of the top plate 21 facing the lower end of the tapered cylinder 15 so that the lower end of the measuring cylinder is positioned above the tapered cylinder 15. If the upper end of the shape tube 15 is loosely inserted into the lower portion of the measuring tube 23, the measuring tube 23 is suspended from the lower surface of the top plate 21 so that the lower end of the measuring tube faces the lower slope of the tapered tube 15. Is also good. Further, in order to form the measuring tap 10 integrally, the rotating member 20 is connected to the fixed cylinder 11 by a thin hinge 27 attached to the rear surface of the flange-shaped top wall 12 described above. A finger hanging piece 26 is provided on the front surface of the top plate 21 so as to protrude outward, and is used when the rotating member 20 is detached from the fixed cylinder 11.

Reference numeral 30 denotes a cap screwed onto the outer surface of the mouth and neck 7. The cap hangs from the outer periphery of the top wall 31 to a peripheral wall 32 provided with a thread on the inner surface, and on the lower surface of the top wall 31,
When the cap is screwed, an annular ridge 33 is provided which comes into pressure contact with the upper surface of the flange-shaped top wall 12. In the illustrated example, the cap 30
Is screwed to the mouth and neck 7, but the cap 30 may be fitted to the outer surface of the mouth and neck 7 using an uneven engagement means.

In the constant volume container 1 having the above structure, when a desired amount of powder is to be supplied, the cap is moved from the state shown in FIG.
After removing 30, pull the finger hanging piece 26 upward,
The rotating member 20 is separated from the fixed cylinder 11 as shown in FIG.
Thereafter, when the container body 2 is tilted, the powder is shaken out from the pouring hole 16.

When dispensing a fixed amount of powder, the cap 30
Then, as shown in FIG. 4, when the container 2 is inverted without removing the rotating member 20 from the fixed cylinder 11, the container 2
The powder inside flows into the measuring cylinder 23 from the pouring hole 16 and accumulates therein. Thereafter, when the upper surface of the powder accumulated in the measuring cylinder 23 becomes flush with the pouring hole 16, the inflow of the powder stops, so that the amount of the powder flowing into the measuring cylinder 23 is always constant.

When the container 2 is erected from the above state, the powder accumulated in the center of the measuring cylinder 23 returns to the inside of the container 2 from the pouring hole 16, but most of the powder accumulated in the measuring cylinder 23 The body falls on the slope of the tapered tube 15 and accumulates in the fitting tube 13 as shown in FIG. When the container body 2 is erected, the measuring cylinder
Since the amount of powder returning from 23 to the container 2 is almost constant,
The amount of powder deposited on the fitting cylinder 13 is also constant. Thereafter, when the container body 2 is turned over again, the powder in the fitting tube 13 is squirted out of the fixed-quantity squirting container 1 through the stored material discharge hole 25 as shown in FIG.
