[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] As shown in FIGS. 1 to 3, in one embodiment of the present invention, a dispensing container 1 includes: (a) A cylindrical case 2 having a horizontal outlet 2a at its upper end for dispensing solid or semi-solid contents (not shown), (b) a cylindrical operating tube 3 that rotates in one circumferential direction relative to the case tube 2 to slide the case tube 2 downward; (c) a cylindrical first screw-tube portion 4 that is integrally provided with the operation tube 3 and has a first male screw portion 4a on its outer peripheral surface, and the first male screw portion 4a screws into the inner peripheral surface of the case tube 2 so as to rotate in one circumferential direction relative to the case tube 2 to lower the case tube 2; (d) a middle dish member 5 having a disk-shaped middle dish portion 5a that supports the bottom surface of the contents, and a cylindrical second screw tube portion 5b that is integral with the middle dish portion 5a and extends downward from the middle dish portion 5a, the middle dish portion 5a engaging with the inner circumferential surface of the case tube 2 via a guide portion 6, the second screw tube portion 5b having a second male screw portion 5b1 that screws into the inner circumferential surface of the first screw tube portion 4, and the operation tube 3 and the first screw tube portion 4 rotating in one circumferential direction relative to the case tube 2, the guide portion 6 guiding the middle dish portion 5a upward by the action of the second male screw portion 5b1 while restricting the rotation of the middle dish portion 5a in one circumferential direction relative to the case tube 2; (e) a shaft member 7 that protrudes upward from an internal space radially inside the second screw barrel portion 5b and supports the bottom of the contents; When a rotation operation is performed to rotate the operating tube 3 in one circumferential direction relative to the case tube 2, the case tube 2 descends relative to the operating tube 3 in response to the rotation operation, while the inner plate member 5 rises relative to the case tube 2 together with the contents and the shaft member 7 that holds the contents, and when it has risen a predetermined amount, the shaft member 7 abuts against a stopper 4b provided on the inner surface of the first screw tube portion 4, stopping the rise (see Figure 2), and thereafter only the inner plate member 5 rises (see Figure 3).

[0012] In this embodiment, the up-down direction is the direction along the central axis O of the case cylinder 2, the upper direction is the direction in which the contents are dispensed and the lower direction is the opposite direction, the radial direction is the direction perpendicular to the central axis O, and the circumferential direction is the direction going around the central axis O. In this embodiment, the case cylinder 2, the operation cylinder 3, the first screw cylinder portion 4, the second screw cylinder portion 5b, and the shaft member 7 are coaxially arranged.

[0013] According to the above configuration, the contents can be well held by the inner plate portion 5a and the tip of the shaft member 7 by the rotation operation and can be dispensed from the operation outlet and used. In addition, since the case tube 2 descends relative to the operation tube 3 as the contents decrease (i.e., the protruding amount X of the case tube 2 from the operation tube 3 decreases), the user can be made to realize that the contents are low before the contents run out. A sign to aid in the perception may be provided on the outer circumferential surface of the case tube 2. In addition, when the remaining contents are low, the shaft member 7 abuts against the stopper 4b, so that the shaft member 7 stops rising, and only the inner plate member 5 rises as shown in FIG. 3. Therefore, even when the remaining contents are low, the shaft member 7 does not get in the way and the contents can be used to the end. Therefore, it is possible to realize a dispensing container 1 that can make the user realize that the contents are low before the contents run out and can reduce the amount of the contents that remain unusable. The contents are not particularly limited, but in this embodiment, they are cosmetics such as lipstick.

[0014] The first male screw portion 4a and the second male screw portion 5b1 are each configured as a double thread, but are not limited to this. The case cylinder 2 has a first convex portion 2b that screws into the first male screw portion 4a at the lower end of the inner peripheral surface of the case cylinder 2, but are not limited to this. The first screw cylinder portion 4 has a second convex portion 4c that screws into the second male screw portion 5b1 at the upper end of the inner peripheral surface of the first screw cylinder portion 4, but are not limited to this. The center plate member 5 has multiple vertical ribs 5c that extend downward from the lower surface of the center plate portion 5a on the outer peripheral surface of the second screw cylinder portion 5b, and the vertical ribs 5c have a lower end surface that abuts against the upper end surface of the first screw cylinder portion 4 before use, but are not limited to this. The guide portion 6 is composed of a guide rib 6a extending in the vertical direction on the inner peripheral surface of the case tube 2 and a groove 6b extending in the vertical direction on the outer peripheral surface of the inner plate portion 5a and engaging with the guide rib 6a, but is not limited to this. More specifically, the guide portion 6 is composed of a plurality of guide ribs 6a and grooves 6b, but the number of guide ribs 6a and grooves 6b constituting the guide portion 6 may be one. The stopper 4b is composed of a downward step surface that abuts against the upper surface of the enlarged diameter portion 7a provided at the lower end of the shaft member 7, but is not limited to this.

[0015] The dispensing container 1 has a case tube stopper 8a that stops the descent of the case tube 2 relative to the operation tube 3 in a maximum dispensing state in which the most of the contents are dispensed in response to a rotation operation, and in the maximum dispensing state, the upper surface of the inner dish portion 5a and the upper end of the shaft member 7 are located at the upper end of the case tube 2 (see FIG. 3). With the above configuration, the amount of remaining contents can be further reduced. The case tube stopper 8a is formed by the upper surface of the connecting portion 8 that extends radially outward from the lower end of the operation tube 3 and connects the lower end of the operation tube 3 with the lower end of the first screw tube portion 4, and stops the descent of the case tube 2 by abutting against the lower end surface of the case tube 2, but is not limited to this.

[0016] The dispensing container 1 has an operating tube member 9 and a first screw tube member 10 which is integrated with the operating tube member 9 by fitting, the operating tube member 9 has an operating tube 3 and a bottom portion 9a extending radially inward from the lower end of the operating tube 3, and the first screw tube member 10 has a first screw tube portion 4 and an extension portion 10a extending radially outward from the lower end of the first screw tube portion 4, and is integrated by fitting the lower surface and outer circumferential surface of the extension portion 10a with the inner circumferential surface of the operating tube 3 and the upper surface of the bottom portion 9a via a concave-convex structure. The bottom portion 9a closes the lower end of the operating tube 3, but is not limited to this. The extension portion 10a and the bottom portion 9a form a connecting portion 8, and the upper surface of the extension portion 10a forms a case tube stopper 8a.

[0017] The case cylinder 2 has a plurality of elastic pieces 2c pressed against the inner peripheral surface of the operation cylinder 3, and the elastic pieces 2c are formed by horizontal U-shaped notches 2d formed in the case cylinder 2. The number of elastic pieces 2c provided on the case cylinder 2 may be single, or the case cylinder 2 may be configured without the elastic piece 2c. The magnitude of resistance to the rotation operation can be optimized by appropriately setting the sliding resistance between the elastic piece 2c and the inner peripheral surface of the operation cylinder 3. The operation cylinder 3 can also be rotated in the other circumferential direction relative to the case cylinder 2, and the contents can be stored in the case cylinder 2 after use by this operation. The dispensing container 1 has a cap 11 that can open and close the dispensing outlet 2a, but is not limited thereto.

[0018] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and the above-described embodiment can be modified in various ways without departing from the gist of the present invention.
