[Diagram 3] FIG. 4 is a partial cross-sectional view of the powder dispensing container showing a state before rotation. [Figure 4] FIG. 4 is a partial cross-sectional view of the body discharge container showing a rotating state. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The powder dispensing container 1 shown in Fig. 1 is a container that contains powder P, such as granular seasonings such as salt or sugar, or powdered medicine, and is capable of stably dispensing a small amount of such powder P at the time of use. Note that the powder P in the present invention includes contents in a granular or powdered form. In the following, the direction along the container axis O will be referred to as the axial direction, the up-down direction or the height direction, the direction perpendicular to the container axis O will be referred to as the radial direction, and the direction circumferentially around the container axis O will be referred to as the circumferential direction.

[0014] First, the configuration of the powder dispensing container 1 will be described. The powder discharge container 1 is composed of a container body 10 that contains powder P, a nozzle 20 that is attached to an opening end 11 formed at the tip of the mouth portion 12 of the container body 10, a screw member 30 that is rotatably arranged inside the nozzle 20, a rotor 40 that is rotatably arranged outside the nozzle 20, and an overcap 50 that covers the upper part (mouth portion 12) of the container body 10, the nozzle 20 and the rotor 40, and each of these components is formed using a predetermined synthetic wood material.

[0015] The container body 10 is a bottomed cylindrical container in which a mouth 12 is provided upright on the upper part of a cylindrical trunk 14 extending upward from a bottom 15 via a shoulder 13 having a reduced diameter and a stepped shape. The powder P is filled into the container body 10 from an open end 11 at the tip of the mouth 12. A male thread 12a is formed on the outer circumferential surface of the mouth 12, and an undercut-shaped engaged portion 12b is formed at the upper end of the male thread 12a.

[0016] The nozzle 20 is formed so that its diameter decreases from the lower end to the upper end. At the lower end of the nozzle 20, an inner cylinder 21 that is in close contact with the inner peripheral surface of the mouth 12 and an outer cylinder 22 that is disposed radially outward are formed via a flange-shaped connecting wall. An engaging portion 23 is provided around the radially inner surface of the outer cylinder 22, and when the nozzle 20 is attached to the upper end of the mouth 12 and the opening end 11 of the mouth 12 is inserted between the inner cylinder 21 and the outer cylinder 22, the engaging portion 23 and the engaged portion 12b can be engaged with each other. An annular engaging groove 24 is provided around the outer peripheral surface of the nozzle 20 (above the connecting wall), and a discharge port 25 that opens in the axial direction is formed at the upper end of the nozzle 20.

[0017] As shown in FIG. 2, the screw member 30 is a member formed to have a diameter that decreases from the lower end to the upper end. In this embodiment, the screw member 30 is arranged inside the nozzle 20 in a state in which it can rotate in the circumferential direction with a small gap between its outer circumferential surface 31 and the inner circumferential surface of the nozzle 20, but the screw member 30 may be arranged so that the outer circumferential surface 31 slides on the inner circumferential surface of the nozzle 20. A helical screw groove 32 is formed on the outer circumferential surface 31 of the screw member 30, a recess 33 (see FIG. 1) is recessed on the upper surface of the screw member 30, and an annular fitting groove 34 is formed around the periphery of the tip side. A communication hole 35 that communicates with the recess 33 is formed in the tip portion 32b of the screw groove 32. When such a screw member 30 is disposed inside the nozzle 20, the recess 33 and the fitting groove 34 are set in a state where they protrude upward from the discharge port 25 of the nozzle 20 (see FIG. 1, FIG. 3 or FIG. 4).

[0018] As shown in FIG. 1, the rotor 40 is a member having a cylindrical side wall 41 that is slightly larger than the nozzle 20, and a top wall 42 with an opening 43 formed at its upper end is provided. A knurl 41a consisting of a plurality of vertical grooves is formed on the lower end side of the outer circumferential surface of the side wall 41, and an engagement protrusion 44 is provided at the lower end of the inner circumferential surface side thereof, which is provided so as to be slidable in the circumferential direction while being engaged with the engagement groove 24 on the nozzle 20 side, and is provided in an annular or intermittent manner along the circumferential direction. Furthermore, a fitting protrusion 45 is formed on the inner edge of the opening 43, which protrudes radially inward and fits tightly enough to be able to rotate together with the fitting groove 34 that protrudes upward from the discharge port 25 of the nozzle 20. When the fitting protrusion 45 is fitted into the fitting groove 34, the screw member 30 and the rotor 40 are connected together, and when the rotor 40 is rotated in the circumferential direction, the screw member 30 also rotates together. Furthermore, even if the mating protrusion 45 is not tightly fitted into the mating groove 34, it is possible for them to rotate together as long as relative rotation is restricted, so a locking portion may be provided to restrict rotation in both or one of the circumferential directions. Also, a locking portion may be provided to restrict rotation in the other direction so that the screw member 30 rotates in only one circumferential direction (the discharge direction) relative to the nozzle 20 .

[0019] The overcap 50 is a topped tubular member in which a cylindrical outer peripheral wall portion 52 and an inner peripheral wall portion 53 are provided vertically from a top wall 51, and a storage portion 50A for storing the rotor 40 and the like is provided inside the inner peripheral wall portion 53. A female screw 53a is formed on the inner peripheral surface of the lower end of the inner peripheral wall portion 53, and can be screwed into a male screw 12a formed on the mouth portion 12 on the container body 10 side. The lower end of the outer peripheral wall portion 52 can be arranged in a state facing the shoulder portion 13 of the container body 10 in the form of a stepped reduced diameter. Furthermore, a short cylindrical plug portion 54 is formed in the center of the lower surface of the top wall 51, which can be fitted into the recess 33 provided on the upper surface of the screw member 30 when the overcap 50 is attached to the container body 10. When the overcap 50 is attached, the plug portion 54 fits into the recess 33 to seal it, making it possible to effectively suppress the scattering of the contents.

[0020] Next, the effects of the powder discharging container 1 having the above-mentioned configuration will be described. To discharge the powder P, after removing the overcap 50 from the powder discharge container 1, the powder discharge container 1 is set in an inverted tilted position as shown in Fig. 3, and the recess 33 on the tip side is placed above the object to be discharged (e.g., above a pot). In this state, the powder P moves downward inside the container body 10 toward the mouth part 12, and some of it enters the base end part 32a of the screw groove 32, but the powder P is not discharged from the recess 33 and the discharge port 25.

[0021] 4, while the container body 10 set in an inverted tilted position is fixed with one hand, the rotating body 40 is rotated in one circumferential direction (discharge direction) with the other hand to rotate the screw member 30 in the same discharge direction. Then, the powder P that has entered the base end 32a of the screw groove 32 is screw-fed together with the rotation of the screw member 30, so that the powder P can be transported little by little along the screw groove 32 toward the tip end 32b. The powder P transported to the tip 32b of the screw groove 32 further moves into the recess 33 through the communicating hole 35, making it possible to evenly eject the powder P from the recess 33 through the ejection port 25 onto an external object.

[0022] In the powder dispensing container 1, the amount of powder P discharged can be increased by increasing the rotation speed of the screw member 30, and the amount of powder P discharged can be decreased by decreasing the rotation speed. In this way, the amount of powder P discharged from the discharge port 25 can be adjusted according to the rotation speed of the rotating body 40 (screw member 30), so even a small amount of powder P can be stably discharged. In addition, since the powder P is not discharged when the rotating body 40 (screw member 30) is not rotated, the powder dispensing container 1 can be easily switched between on (dispensing operation) and off (non-dispensing operation).

[0023] Also, it is possible to accommodate various powders P having different particle sizes by changing the groove width or depth constituting the screw groove 32. Furthermore, the amount of discharge per rotation can be adjusted to a desired amount by appropriately setting the groove width and depth constituting the screw groove 32 or the number of spiral pitches.

[0024] As described above, the present invention is configured so that powder P is discharged simply by rotating the rotor 40, and therefore the powder dispensing container 1 can be made easy to operate and understand.

[0025] Although the configuration and the effects of the present invention have been described above based on the embodiments, the present invention is not limited to the above embodiments. For example, in the above embodiment, a configuration including the overcap 50 has been shown and described, but if priority is given to the ejection function, a configuration without the overcap 50 is also possible.

[0026] In the above embodiment, the operation during ejection is described as rotating the rotating body 40 while the container body 10 is fixed. However, since the container body 10 and the rotating body 40 are in a relative relationship in the circumferential direction, it is also possible to operate the container body 10 by rotating the rotating body 40 while fixing it.

[0027] In the above embodiment, the contents P are ejected from the recess 33 provided on the upper part of the screw member 30. However, if the recess 33 is not provided, a gap may be formed between the outer peripheral surface 31 of the screw member 30 and the inner peripheral surface of the nozzle 20, and the contents P may be ejected from the gap. If the recess 33 is provided, the contents P may be ejected from both the recess 33 and the gap. [Industrial Applicability]

[0028] The present invention can expand the range of applications in the field of powder dispensing containers to an even wider range. [Explanation of symbols]
