BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.
Embodiment 1.
1 and 2 are diagrams illustrating the overall configuration of a raw material discharge container 100 according to Embodiment 1 of the present invention. 1 and 2, the positive direction of the X-axis is defined as the front, and the negative direction of the X-axis is defined as the rear. Also, the positive direction of the Z-axis is defined as upward, the negative direction of the Z-axis is defined as downward, and gravity acts in the negative direction of the Z-axis.

The raw material discharge container 100 includes a canister 1 containing powdered raw materials such as tea and coffee. The canister 1 has a rectangular parallelepiped peripheral wall 11 made of resin and an internal space 10 defined by the peripheral wall 11 . A powder raw material is accommodated in the internal space 10 . A cover 5 is detachably attached to the upper portion of the canister 1 .

A raw material extrusion port 11 d is formed in the lower front portion of the canister 1 . A cylindrical cap 4 functioning as a discharge portion is attached to the raw material extrusion port 11d. Note that the canister 1 and the cap 4 may be integrally formed. A cap cover 6 is detachably attached to the front opening 4a of the cap 4. As shown in FIG.

A raw material discharge path 7 is formed between the cap 4 and the cap cover 6 . A raw material discharge port 16 that opens downward is formed in the lower portion of the raw material discharge path 7 . The raw material discharge port 16 communicates with the internal space 10 of the canister 1 via the cylindrical cap 4 .

A cylindrical screw 3 is arranged at the inner bottom of the canister 1 . A helical projection 3a is formed on the outer surface of the screw 3 . The inside of the screw 3 is hollow, the front end 3b is closed, and the rear end 3c is open.

The screw 3 extends in the front-rear direction inside the canister 1 . A front end portion 3b of the screw 3 protrudes from the interior of the canister 1 through the raw material extrusion port 11d and extends to the interior of the cap 4 .

A drive shaft mounting opening 11c is formed in the lower rear portion of the peripheral wall 11 of the canister 1. As shown in FIG. A drive shaft 2 connected to the screw 3 is rotatably attached to the drive shaft attachment port 11c.

One end of a rod-shaped stirring member 8 is attached to the rear upper portion of the peripheral wall 11 of the canister 1 . The other end of the stirring member 8 is in contact with the outer surface of the screw 3 . A rectangular stirring frame 8 a is integrally formed with the stirring member 8 in the vicinity of the screw 3 .

When the drive shaft 2 is driven to rotate by a motor (not shown) outside the canister 1, the screw 3 attached to the drive shaft 2 also rotates integrally. As the screw 3 rotates, the end of the stirring member 8 contacting the outer surface of the screw 3 is periodically pushed up by the helical projection 3 a of the screw 3 . As a result, the stirring frame 8 a is periodically rocked back and forth and left and right above the screw 3 . By such movement of the stirring frame 8a, the raw material powder in the canister 1 is sufficiently stirred.

As the screw 3 rotates, the raw material powder in the canister 1 is transported forward in the canister 1 by the helical protrusions 3 a formed on the outer surface of the screw 3 . The powder raw material conveyed forward in the canister 1 is extruded into the cap 4 through the raw material extrusion port 11 d and then conveyed toward the opening 4 a of the cap 4 .

Next, the configuration around the raw material discharge port 16 in the raw material discharge container 100 according to Embodiment 1 of the present invention will be described with reference to FIG.

As shown in FIG. 3, an upwardly inclined portion 4b is formed at the lower portion of the opening portion 4a of the cap 4. As shown in FIG. As described above, the inclined portion 4b prevents the raw material powder from naturally falling from the opening 4a.

An R surface (curved surface) 6a is formed on the inner upper portion of the cap cover 6. As shown in FIG. The starting position r1 of the R surface 6a is the upper end 4c of the opening 4a of the cap 4. As shown in FIG. The end position r2 of the R surface 6a is at the same height as the inclined portion 4b of the opening 4a of the cap 4. As shown in FIG. Further, the horizontal distance L from the start position r1 to the end position r2 of the R surface 6a is formed to be longer than the maximum length W between the helical projections 3a, 3a of the screw 3.

When the screw 3 is driven to rotate by a motor (not shown), the raw material powder contained in the canister 1 is conveyed forward through the canister 1 by the helical projections 3a formed on the outer surface of the screw 3. . The powder raw material conveyed forward in the canister 1 is extruded into the cap 4 through the raw material extrusion port 11 d and then conveyed toward the opening 4 a of the cap 4 .

In the vicinity of the opening 4a of the cap 4, the raw material powder conveyed from the upper side of the screw 3 becomes a mass and is pushed out horizontally as indicated by an arrow A1. Further, the raw material powder conveyed from the lower side of the screw 3 also becomes lumps and is pushed out obliquely upward as indicated by the arrow A2.

The bulky powdery raw material extruded along the arrow A1 and the bulky powdery raw material pushed out along the arrow A2 merge at the opening 4a and are pushed out to the raw material discharge path 7. FIG. At this time, the joined powdery raw material is pushed out into the raw material discharge path 7 obliquely upward, in other words, along the extension line E of the inclined portion 4b of the opening 4a of the cap 4. As shown in FIG.

As described above, the inner upper portion of the cap cover 6 is formed with the rounded surface 6a. After reaching the rounded surface 6 a , the bulk powder raw material extruded from the raw material extrusion port 11 d to the raw material discharge path 7 advances downward along the rounded surface 6 a while losing its shape and is discharged from the raw material discharge port 16 . The powder raw material discharged from the raw material discharge port 16 is mixed with hot or cold water to prepare a beverage.

As described above, in the raw material discharge container 100 according to Embodiment 1 of the present invention, the inner upper portion of the cap cover 6 is formed with the rounded surface 6a. The bulky powdery raw material extruded from the raw material extrusion port 11d to the raw material discharge path 7 is compressed in the raw material discharge path 7 and does not stay there, and when it reaches the R surface 6a, it loses its shape and moves downward along the R surface 6a. , and discharged from the raw material discharge port 16 . This prevents the raw material discharge path 7 from being clogged with the raw material powder.

In addition, the amount of raw material powder extruded during one rotation of the screw 3 is determined by the maximum length W between the helical projections 3a, 3a. Therefore, when the next lump of powder material is pushed out before the lump of powder material extruded during one rotation of the screw 3 reaches the R surface 6a and collapses, the powder material is compressed on the R surface 6a. There is a possibility that the raw material discharge path 7 will be clogged. In order to prevent this, in the raw material discharge container 100 according to Embodiment 1 of the present invention, the horizontal distance L from the start position r1 to the end position r2 of the R surface 6a is is formed to be longer than the maximum length W of the This also prevents clogging of the raw material discharge path 7 with the raw material powder.

In the raw material discharge container 100 according to Embodiment 1 of the present invention, since the powdery raw material does not clog the raw material discharging path 7, the powdery raw material flows smoothly and the powdery raw material can be stably discharged. . In addition, since the raw material powder flows smoothly, the load on the motor (not shown) that drives the screw 3 to rotate is reduced. Furthermore, since the raw material discharging path 7 is not clogged with the raw material powder, the inside of the cap cover 6 can be washed easily.

Further, in the first embodiment described above, the cap cover 6 is detachably attached to the opening 4a of the cap 4 . This makes it possible to easily wash the cap cover 6 .

In the first embodiment described above, the starting position of the R surface 6a is the upper end portion 4c of the opening 4a of the cap 4. As shown in FIG. The end position r2 of the R surface 6a was at the same height as the inclined portion 4b of the opening 4a of the cap 4. FIG. More generally, in FIG. It is sufficient if it is between the inner side and the position P where it collides. Also, the end position r2 of the R surface 6a may be lower than the position P.

Embodiment 2.
Next, the configuration around the raw material discharge port 216 in the raw material discharge container 200 according to Embodiment 2 of the present invention will be described with reference to FIGS. 4 and 5. FIG.

As shown in FIGS. 4 and 5, in the opening 204a of the cap 204 according to the second embodiment, an upwardly inclined plate-like guide portion 204d is formed between the upper end portion 204c and the inclined portion 204b. It is A tip portion 204e of the guide portion 204d extends forward (in the positive direction of the X axis) from the inclined portion 204b.

The start position r1 of the R surface 206a formed inside the cap cover 206 is such that a line extending vertically upward (in the positive direction of the Z axis) from the tip 204e of the guide portion 204d of the cap 204 is aligned with the inside of the cap cover 206. This is the position of collision. The end position r2 of the R surface 206a is at the same height as the inclined portion 4b of the opening 4a of the cap 4. As shown in FIG.

More generally, in FIG. 4, the start position r1 of the R surface 206a is the position where the line extending vertically upward from the tip 204e of the guide portion 204d of the cap 204 collides with the inside of the cap cover 206, and the opening of the cap 204. It is sufficient if the extension line of the inclined portion 204b of the portion 204a is between the inside of the cap cover 206 and the position where it collides. The end position r2 of the R surface 206a may be below the position where the extension of the inclined portion 204b of the opening 204a of the cap 204 collides with the inside of the cap cover 206. FIG.

In this Embodiment 2, as in Embodiment 1, the raw powder material conveyed from the upper side of the screw 3 becomes lumpy in the vicinity of the opening 204a of the cap 204, and moves horizontally as shown by the arrow A1. pushed out. Further, the raw material powder conveyed from the lower side of the screw 3 also becomes lumps and is pushed out obliquely upward as indicated by the arrow A2.

The bulk powder raw material extruded along the arrow A1 advances on the upper side of the guide portion 204d, reaches the R surface 206a beyond the tip portion 204e of the guide portion 204d, and loses its shape as indicated by the arrow B1. while advancing along the R surface 206a. In addition, the bulk powder raw material extruded along the arrow A2 goes over the inclined portion 204b and travels under the guide portion 204d as indicated by the arrow B2.

At this time, the raw material powder advancing along the arrow B1 covers the raw material powder advancing along the arrow B2, so that both advance directions are downward (negative direction of the Z-axis). The powder raw material advancing downward freely falls while losing its shape and is discharged from the raw material discharge port 216 . The powder raw material discharged from the raw material discharge port 216 is mixed with hot or cold water to prepare a beverage.

As described above, in the raw material discharge container 200 according to Embodiment 2 of the present invention, the upwardly inclined guide portion 204d is formed between the upper end portion 204c of the opening portion 204a of the cap 204 and the inclined portion 204b. The tip portion 204e of the guide portion 204d extends further forward than the inclined portion 204b. As a result, clogging of the powder raw material in the raw material discharge path 207 is more reliably prevented.

In addition, the raw material powder extruded from the opening 204a of the cap 204 is divided into the raw material powder that advances along the arrows A1 and B1 and the raw material powder that advances along the arrows A2 and B2. It is possible to prevent unevenness from occurring in the powder raw material that freely falls. As a result, the raw material powder can be released smoothly.
