On the other hand, as shown in FIG. 4, the gear portion 22 has a plurality of (12) locking surfaces 22a integrally provided on the inner peripheral surface of the case body 10, and a plurality of locking surfaces 22a integrally provided on the inner peripheral surface of the case body 10. It has a plurality (12) of crossing surfaces 22b. Each locking surface 22a engages with the claw piece 21c and locks the claw portion 21 when the operating member 14 rotates relative to the case body 10 in the second circumferential direction at the initial position. It is configured to prevent relative rotation of the operating member 14 with respect to the case body 10 in the second circumferential direction. Each crossing surface 22b extends between two adjacent locking surfaces 22a in a curved manner from a radially outer portion of one locking surface 22a to a radially inner portion of the other locking surface 22a. When the operating member 14 rotates relative to the case body 10 in the first circumferential direction at the initial position, the claw piece 21c of the claw portion 21 is guided so as to overcome the locking surface 22a. is configured to allow relative rotation in the first circumferential direction with respect to the case body 10.

Note that the number of pawls 21 and locking surfaces 22a to overcoming surfaces 22b provided in the ratchet mechanism section 20 can be changed in various ways.

As shown in FIG. 1, the dispensing container 1 of the present embodiment has a sliding resistance between the operating member 14 and the case body 10 when the operating member 14 rotates relative to the case body 10 in the circumferential direction. It can be configured to include a sliding resistance imparting section 30 that imparts. The sliding resistance imparting section 30 is provided integrally with the operation main body member 15 and elastically contacts the inner circumferential surface of the case body 10 in a portion between the cap 13 and the ratchet mechanism section 20, so that the operation member It is configured to apply sliding resistance between the operating member 14 and the case body 10 when the operating member 14 rotates relative to the case body 10 in the circumferential direction.

As shown in FIGS. 2, 3, and 5, in this embodiment, the sliding resistance imparting section 30 includes a pair of pillar sections 31, a support body 32, four elastic protrusions 33, and four sliding protrusions. 34.

More specifically, the pair of pillar portions 31 are provided at the upper ends of the engagement cylinder portions 15b of the operation main body member 15, and are integrally connected between the pair of leg portions 21a. The pair of pillar portions 31 extend upward from the engagement cylinder portion 15b between the shaft body 12 and the case body 10. The upper ends of the pair of column parts 31 are located above the leg parts 21a.

The support body 32 has a cylindrical shape that is coaxial with the engagement cylinder portion 15b, and is provided integrally at the upper ends of the pair of column portions 31. The support body 32 is arranged between the shaft body 12 and the case body 10.

The four elastic protrusions 33 each have an elongated plate shape, and are provided integrally in series at the upper end of the support body 32 at equal intervals in the circumferential direction. Each elastic protrusion 33 extends upward from the support 32 and is elastically deformable in the radial direction using the support 32 as a fulcrum. Note that the intervals between the four elastic protrusions 33 in the circumferential direction do not have to be equal. Further, the number of elastic protrusions 33 can be changed in various ways.

Note that the column portion 31, the support body 32, and the elastic projection piece 33 are each arranged at intervals with respect to the inner circumferential surface of the case body 10.

The four sliding protrusions 34 are integrally provided on the outward facing surface of the tip (upper end) of the corresponding elastic protruding piece 33, and each protrudes radially outward from the surface. As shown in FIG. 1, each sliding protrusion 34 is in contact with the inner circumferential surface of the case body 10, with the elastic protrusion 33 elastically deformed radially inward using the support 32 as a fulcrum. There is. In this way, the sliding protrusion 34 is in elastic contact with the inner circumferential surface of the case body 10, so that when the operating member 14 rotates relative to the case body 10 in the circumferential direction, the operating member 14 Sliding resistance is provided between and the case body 10. The sliding resistance that the sliding resistance applying unit 30 applies between the operating member 14 and the case body 10 is determined by conducting experiments in advance, taking into consideration the operability when drawing out the solid contents 2 from the case body 10. It can be set to an appropriate value.

As shown in FIG. 1, the shaft body 12 is arranged on the radially outer side of the screw shaft 16a. In the shaft body 12, a locking projection 13d provided on the inner peripheral surface of the peripheral wall portion 13a of the cap 13 is locked in an annular locking groove 12a provided on the outer peripheral surface of the upper end portion, and a locking protrusion 13d provided on the inner peripheral surface of the peripheral wall portion 13a of the cap 13 is locked. Since the spline portion 17 is provided between the spline portion 17 and the peripheral wall portion 13a, the spline portion 17 is fitted and fixed to the cap 13 in a rotation-prevented state. Therefore, the shaft body 12 can move relative to the cap 13 in the vertical direction while being prevented from rotating with respect to the case body 10.

As shown in FIGS. 1, 6, and 7, the shaft body 12 is provided with internal threads 12b on its inner circumferential surface that can be elastically displaced radially outward from a state in which the shaft body 12 is threadedly connected to the threaded shaft 16a, and at equal intervals in the circumferential direction. It has a pair of elastic pieces 12c spaced apart from each other.

In this embodiment, each elastic piece 12c has a cantilever shape having an upper end that is a fixed end and a lower end that is a free end. Further, the pair of elastic pieces 12c are formed by a pair of slits 12d extending upward from the lower end of the shaft body 12.

Note that the number of elastic pieces 12c provided on the shaft body 12 can be changed in various ways.

As shown in FIG. 1, a cylindrical mounting tube 18 is mounted on the outer peripheral surface of the shaft body 12 at a predetermined height so as to circumferentially surround the shaft body 12 including the elastic piece 12c. That is, the feeding member 11 has the mounting tube 18. In this embodiment, the mounting tube 18 is integrally continuous along the entire circumference in the circumferential direction.

The upper end portions of the pair of elastic pieces 12c and the pair of slits 12d on the outer peripheral surface of the shaft body 12 allow the mounting tube 18 to move downward due to elastic deformation, and allow the mounting tube 18 to be moved from the predetermined height. An annular upper restricting convex portion 12e is integrally provided to restrict upward movement. Note that the shape of the upper regulating convex portion 12e is not limited to an annular shape.

An arc-shaped lower restricting convex portion 12f that restricts downward movement of the mounting tube 18 from the predetermined height is integrally provided at the lower end of the outer circumferential surface of the pair of elastic pieces 12c. Note that the shape of the upper regulating convex portion 12e is not limited to an arc shape.

The mounting cylinder 18 is arranged between the upper regulating protrusion 12e and the lower regulating protruding part 12f, so that its relative position in the vertical direction with respect to the shaft body 12 is maintained at the predetermined height. Moreover, since the mounting tube 18 is mounted on the shaft body 12 at the predetermined height, elastic deformation of the pair of elastic pieces 12c toward the outside in the radial direction is suppressed. In other words, the outer circumferential surfaces of the pair of elastic pieces 12c are supported by the inner circumferential surface of the mounting cylinder 18 from the outside in the radial direction, thereby suppressing the elastic deformation of the pair of elastic pieces 12c radially outward, and the male thread 16b and the female thread 12b is maintained.

As shown in FIG. 1, on the inner peripheral surface of the gripping portion 15a, a plurality (three) of vertical ribs 15f that extend in the vertical direction and whose lower ends abut against the upper surface of the connecting plate 16d of the screw shaft member 16 are provided in the circumferential direction. They are integrally provided at equal intervals, and the mounting tube 18 has a cut 18a formed by breaking from these vertical ribs 15f. The cut 18a is formed on the inner circumferential surface of the operation main body member 15, including the inner circumferential surfaces of the pair of claws 21 and the plurality of elastic protrusions 33, when the shaft body 12 and the mounting cylinder 18 rise as the screw shaft 16a rotates. It is arranged so that it can rise above these without interfering with the

That is, the mounting tube 18 is integrally formed with the operating body member 15 by injection molding of a synthetic resin material, and then is separated from the operating body member 15 by breaking during the assembly process of the feeding container 1. As shown in FIGS. 9 and 10, in the state before separation, the operation main body member 15 and the mounting tube 18 are arranged coaxially, and the lower end of the inner peripheral surface of the plurality of vertical ribs 15f of the operation main body member 15 It is connected to the upper end of the outer circumferential surface of the mounting cylinder 18 by a connecting piece 19 . Then, when the dispensing container 1 is assembled, each connecting piece 19 is broken, so that the operation main body member 15 and the mounting tube 18 are separated. That is, the breakage of the connecting piece 19 forms the cut 18a of the mounting tube 18.

In this embodiment, the overcap 3, the case body 10, the cap 13, the shaft body 12, and the screw shaft member 16 are each integrally formed by injection molding of a synthetic resin material.

In the dispensing container 1 of the present embodiment having the above configuration, when the overcap 3 is removed from the case body 10, the operation member 14 is held by one hand while holding the case body 10 with one hand or the like. By rotating the operating member 14 relative to the case body 10 in the first circumferential direction by gripping the portion 15a and rotating it in the first circumferential direction, the solid contents 2 are delivered to the dispensing opening of the case body 10. It can be drawn out from 10a.

That is, when the operating member 14 is rotated relative to the case body 10 in the first circumferential direction, the male screw 16b is rotated together with the operating member 14 relative to the case body 10 in the first circumferential direction. The shaft body 12 equipped with the female thread 12b screwed to the male thread 16b is prevented from rotating by the case body 10 together with the cap 13, so that when the male thread 16b rotates relative to the case body 10 in the first circumferential direction, the male thread 16b The shaft body 12, which is provided with a female thread 12b that is threadedly connected to the cap 12, is raised by the screw action of the male thread 16b and the female thread 12b, and pushes up the cap 13. As a result, the solid contents 2 are pushed up by the rising cap 13 and are delivered to the outside of the case body 10 through the delivery opening 10a. The amount by which the solid contents 2 are fed out (the amount of protrusion) from the case body 10 can be adjusted by the amount by which the operating member 14 is relatively rotated. Therefore, by rotating the operating member 14 relative to the case body 10 by a desired amount in the first circumferential direction, a desired amount of solid contents 2 can be dispensed from the dispensing port 10a of the case body 10 and used. I can do it.

On the other hand, when the operating member 14 is rotated relative to the case body 10 at the initial position in the second circumferential direction opposite to when the solid contents 2 are fed out, the ratchet mechanism 20 prevents the relative rotation. be done. Therefore, even if the operating member 14 is suddenly operated to rotate relative to the case body 10 in the second circumferential direction, the feeding member 11 supporting the lower end side portion of the solid content 2 will not descend. This prevents the solid contents 2 from being drawn into the inside of the case body 10. Therefore, even if a solid content 2 such as a relatively soft lipstick is stored in the case body 10 with such hardness that it is not preferable to insert it into the case body 10, the operating member 14 may unexpectedly move against the case body 10. It is possible to prevent the solid contents 2 from being damaged such as deformation or breakage due to being operated so as to rotate relative to each other in the circumferential direction.

The feeding container 1 having the above structure is assembled through the steps shown in FIGS. 11 to 14.

First, as shown in FIG. 11, the shaft body 12 is assembled to the screw shaft member 16 from above. At this time, the elastic piece 12c of the shaft body 12 is elastically deformed radially outward, so that the female thread 12b is elastically displaced radially outward and can overcome the male thread 16b downward, so that the shaft body 12 can be attached to the screw shaft member. Assembling can be achieved by a simple operation of simply sliding it downward without rotating it with respect to 16. The threaded shaft 16a is inserted into the shaft 12 until the lower end of the shaft 12 comes into contact with the upper surface of the connecting plate 16d of the threaded shaft member 16, thereby completing the assembly of the threaded shaft member 16 and the shaft 12.

In addition, when forming the shaft body 12 prior to assembly, the elastic piece 12c elastically deforms outward in the radial direction, so that the female thread 12b is formed along the axis O without rotating the mold corresponding to the female thread 12b. Since the shaft body 12 can be detached (that is, forcibly removed) from the shaft body 12, it is possible to easily form the shaft body 12.

Next, as shown in FIG. 12, the integrally molded member of the mounting tube 18 and the operation main body member 15 is assembled into the above assembly from above. At this time, the shaft body 12 is attached to the mounting tube 18 until the mounting tube 18 passes over the upper regulating convex portion 12e of the shaft body 12 and the lower end of the attaching tube 18 comes into contact with the upper surface of the lower regulating convex portion 12f of the shaft body 12. inserted.

Further, by pushing down the operation body member 15 with respect to the assembled product, the connecting piece 19 connecting the mounting tube 18 and the operation body member 15 is broken, and as shown in FIG. 13, the operation body member 15 is broken. is fitted onto the screw shaft member 16. Then, as shown in FIG. 14, the cap 13 is fitted onto the upper end of the shaft body 12 from above, and then the case body 10 is fitted onto the operation main body member 15 from above.

In this embodiment, each elastic piece 12c is formed by a pair of slits 12d extending upward from the lower end of the shaft body 12, but as in the modification shown in FIGS. It may also be formed by a slit 12d. In this modification, an annular lower regulating convex portion 12f disposed coaxially with the axis O is integrally provided at the lower end of the shaft body 12. Note that in FIGS. 15 and 16, elements corresponding to those shown in FIGS. 1 to 14 are given the same reference numerals.

As described above, in the feeding container 1 of the present embodiment, the mounting cylinder 18 is attached to the outer peripheral surface of the shaft body 12 at the predetermined height so as to circumferentially surround the shaft body 12 including the elastic piece 12c. Because of this, when assembling the shaft body 12 to the screw shaft 16a, the assembly can be completed simply by elastically deforming the elastic piece 12c radially outward and sliding it downward. Further, by subsequently attaching the mounting tube 18, elastic deformation of the elastic piece 12c toward the outside in the radial direction can be suppressed, thereby stably maintaining the threaded connection between the screw shaft 16a and the female thread 12b of the elastic piece 12c. can do. Therefore, easy assembly can be achieved while maintaining operability.

Further, in the feeding container 1 of the present embodiment, the feeding member 11 is provided with the shaft body 12 and the guided portion 13c guided by the guide rail portion 10b, and is prevented from rotating by the upper end portion of the shaft body 12.
