DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, a fixed-volume discharge container 1, which is one embodiment of the fixed-volume discharge container according to the present invention, will be described with reference to the drawings. In the following description, "front" refers to the side where a front wall 4f (described later) is located, and "rear" refers to the side where a rear wall 4g (described later) is located. In addition, "upper" refers to the side where a second guide wall 2h (described later) is located relative to a first guide wall 2d (described later), and "lower" refers to the opposite side. In the following description, the orientations are used for convenience of explanation, and do not mean that the fixed-volume discharge container 1 is used only in those orientations.

[0014] The fixed-amount discharge container 1 comprises a container body 2, a lid 3, a sliding member 4, and a rotating member 5. All of these members are made of synthetic resin. The container body 2 and the lid 3 correspond to the "container" in this specification. The fixed-amount discharge container 1 is also relatively small in size, making it suitable for easy portability.

[0015] As shown in Figs. 1A and 1B, the container body 2 includes a rear wall 2a and a peripheral wall 2b rising from the outer edge of the rear wall 2a. As shown in Fig. 1B, a partition wall 2c is provided inside the rear wall 2a, which extends laterally from the peripheral wall 2b, then extends in an arc, and further extends vertically. A first guide wall 2d extending laterally from the front to the rear is connected to the upper end of the partition wall 2c. An outer arc-shaped guide wall 2e extending in an arc is connected to the rear end of the first guide wall 2d. An inner arc-shaped guide wall 2f is provided inside the outer arc-shaped guide wall 2e, which has the same center as the outer arc-shaped guide wall 2e and has a gap between it and the outer arc-shaped guide wall 2e. The outer arc-shaped guide wall 2e and the inner arc-shaped guide wall 2f each correspond to the "arc-shaped guide wall" in this specification. A shaft portion 2g is provided on the inside of the inner arcuate guide wall 2f, the shaft portion 2g being coaxial with the outer arcuate guide wall 2e and the inner arcuate guide wall 2f.

[0016] The container body 2 also includes a second guide wall 2h that rises from the rear wall 2a and extends laterally with a predetermined gap between it and the first guide wall 2d, and a pair of discharge walls 2j that extend vertically with a predetermined gap between them. A guide groove 2k that cuts out the rear wall 2a and extends laterally is provided between the first guide wall 2d and the second guide wall 2h.

[0017] The lid body 3 has a flat front wall 3a having substantially the same shape as the rear wall 2a. Although not shown, the front wall 3a is provided with a fitting portion that fits inside the peripheral wall 2b and is fitted and held by the peripheral wall 2b, and the lid body 3 is held by the container body 2.

[0018] Here, when the lid 3 is attached to the container body 2, the space defined by the rear wall 2a, the peripheral wall 2b, the partition wall 2c, and the front wall 3a is referred to as the storage space S1. The powder contents are stored in the storage space S1. The outlet of the gap defined between the vertically extending portion of the partition wall 2c and the peripheral wall 2b is referred to as the communication port M1. And the outlet of the gap defined between the pair of discharge walls 2j is referred to as the discharge port M2.

[0019] The slide member 4 includes a slide rear wall 4a that is provided so as to be overlapped with the rear wall 2a. A guide protrusion 4b that is inserted into the guide groove 2k is provided on the rear side of the slide rear wall 4a. A pair of slide peripheral walls 4c that are located inside the first guide wall 2d and the second guide wall 2h and extend in the horizontal direction are provided on the front side of the slide rear wall 4a. The center of the slide peripheral wall 4c is cut out, and a pair of partition walls 4d that connect the pair of slide peripheral walls 4c are provided in the cut-out portion. Here, the space that is partitioned by the slide rear wall 4a, the pair of partition walls 4d, and the front wall 3a when the slide member 4 is attached to the container body 2 and the lid body 3 is referred to as a measurement space S2. A stopper 4e that extends downward from the partition wall 4d located in the front is provided on the slide peripheral wall 4c located on the lower side.

[0020] The slide member 4 also has a front wall 4f that connects the pair of slide peripheral walls 4c at the front. The front wall 4f extends at an incline from the front to the rear as it goes from the bottom to the top. The front wall 4f is a portion that corresponds to the "inclined portion" in this specification. The slide member 4 also has a rear wall 4g that connects the pair of slide peripheral walls 4c at the rear. The lower part of the rear wall 4g extends in an arc shape.

[0021] The rotating member 5 includes an elastic piece 5a having an arc shape as shown in FIG. 2A to FIG. 2C. The elastic piece 5a can be elastically deformed toward the inside in the radial direction. The elastic piece 5a is shaped to fit in the gap between the outer arc-shaped guide wall 2e and the inner arc-shaped guide wall 2f as shown in FIG. 1B. A plate-shaped base wall 5b is provided on the inside in the radial direction of the elastic piece 5a. The base wall 5b is provided with a generally circular shaft hole 5c having the same center as the elastic piece 5a. A connecting wall 5d extending vertically is provided on the upper part of the elastic piece 5a. A cover portion 5e is connected to the connecting wall 5d. The cover portion 5e of this embodiment is shaped to extend laterally in front of the connecting wall 5d, then extend in an arc shape, and further extend vertically, and is shaped to extend laterally and then extend in an arc shape on the radial outside of the elastic piece 5a in the rear of the connecting wall 5d.

[0022] The fixed-quantity discharge container 1 made of such members is assembled by inserting the shaft portion 2g into the shaft hole 5c, inserting the guide protrusion 4b into the guide groove 2k, and fitting the lid 3 to the container body 2, as shown in Fig. 1B. Here, the position where the slide member 4 moves backward and the measurement space S2 communicates with the discharge port M2 as shown in Fig. 1B is called the "discharge position", and the position where the slide member 4 moves forward and the measurement space S2 communicates with the communication port M1 as shown in Fig. 3 is called the "measurement position". In addition, the position where the cover portion 5e of the rotating member 5 covers the discharge port M2 and the slide member 4 as shown in Fig. 1B is called the "closed position", and the position where the cover portion 5e is rotated about 90° from the "closed position" and separated from the discharge port M2 and the slide member 4 as shown in Fig. 3 is called the "open position".

[0023] 1B, when the slide member 4 is in the discharge position and the rotation member 5 is in the closed position, the slide member 4 is covered by the cover portion 5e, so that the slide member 4 cannot be inadvertently operated. In this state, the communication port M1 leading to the storage space S1 is closed by the slide member 4, so that the powder content stored in the storage space S1 can be prevented from spilling out of the fixed-quantity dispensing container 1. In this state, the elastic piece 5a is located away from the slide member 4 as shown in FIG. 1B.

[0024] When the rotating member 5 is rotated toward the open position as shown in FIG. 3, the elastic piece 5a comes into contact with the rear wall 4g of the sliding member 4, and the sliding member 4 moves to the metering position. Since the lower part of the rear wall 4g extends in an arc shape, the elastic piece 5a comes into contact with the rear wall 4g without getting caught. Furthermore, since the elastic piece 5a is accommodated in the gap between the outer arc-shaped guide wall 2e and the inner arc-shaped guide wall 2f, the rotating member 5 can be rotated stably. Furthermore, when the sliding member 4 moves to the metering position, the stopper 4e comes into contact with the peripheral wall 2b, so that the sliding member 4 does not move excessively forward.

[0025] 3, the measurement space S2 communicates with the communication port M1. Therefore, by changing the attitude of the fixed-quantity discharge container 1 so that the measurement space S2 is located below the storage space S1, the powder content stored in the storage space S1 can be moved to the measurement space S2.

[0026] Next, when the slide member 4 is pushed from the front to the rear to move it to the discharge position as shown in Fig. 4, the measurement space S2 communicates with the discharge port M2, so that a predetermined amount of powder content contained in the measurement space S2 can be discharged from the discharge port M2. Note that when the slide member 4 moves to the discharge position, the communication port M1 is closed as shown in Fig. 4, so the powder content in the storage space S1 is not discharged to the outside.

[0027] In the state shown in Fig. 4, the elastic piece 5a is elastically deformed by the pushed-in slide member 4, and the slide member 4 is biased from the rear to the front. Therefore, when the pressure on the slide member 4 is released, the slide member 4 moves to the measurement position shown in Fig. 3. Therefore, if the attitude of the fixed-quantity dispensing container 1 is changed so that the measurement space S2 is again positioned lower than the storage space S1, the powder content stored in the storage space S1 can be moved to the measurement space S2, and by pushing the slide member 4 again, a predetermined amount of the powder content can be discharged again from the discharge port M2. In this way, according to the fixed-quantity dispensing container 1 of this embodiment, a predetermined amount of the powder content can be discharged every time the slide member 4 is pressed.

[0028] After the powder contents have been discharged, the rotating member 5 is rotated toward the closed position as shown in Fig. 1B. At this time, the elastic piece 5a is separated from the sliding member 4. The front wall 4f of the sliding member 4 extends at an incline that inclines from the front to the rear as it moves from the bottom to the top. In other words, even if the sliding member 4 is moving forward, the cover portion 5e can come into contact with the front wall 4f and move the sliding member 4 backward.

[0029] 5A and 5B, a fixed-quantity discharge container 1A will be described, which is a modified example of the fixed-quantity discharge container 1. The fixed-quantity discharge container 1A includes a lid 3A in place of the lid 3 described above.

[0030] The lid body 3A has a second outlet M3 that communicates with the storage space S1 separately from the communication port M1. In this embodiment, the second outlet M3 is a circular hole that penetrates the lid body 3A, and a total of five second outlets M3 are provided. The lid body 3A also has a lid wall portion 3b that is bendably connected to the lid body 3A. The lid wall portion 3b has a protrusion portion 3c that is inserted into the second outlet M3 when the lid is closed.

[0031] According to such a fixed-quantity dispensing container 1A, a predetermined amount of powder content can be discharged by operating the slide member 4 in the same manner as the above-mentioned fixed-quantity dispensing container 1. Moreover, by opening the cover wall portion 3b, a desired amount of powder content can be discharged from the second discharge port M3.

[0032] Although one embodiment of the present invention has been described above, the present invention is not limited to the specific embodiment, and various modifications and changes are possible within the scope of the spirit of the present invention described in the claims unless otherwise specifically limited in the above description. For example, the configuration of the above-mentioned embodiment can be appropriately added or deleted, and the configuration of one embodiment can be applied to another embodiment. Furthermore, the effects of the above-mentioned embodiment are merely examples of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above-mentioned effects.

[0033] For example, in this embodiment, both the outer arc-shaped guide wall 2e and the inner arc-shaped guide wall 2f are provided as the "arcuate guide wall", but only one of them may be provided. [Explanation of symbols]
