Embodiments of the present invention will be described below by way of example with reference to the drawings. Note that the same reference numerals are given to corresponding elements in all the figures.

In addition, in this specification, the vertical direction means the direction along the axis O of the case body 10, the upper direction means the direction in which the solid contents 2 are fed out, the lower direction means the opposite direction, and the circumferential direction means the direction along the axis O of the case body 10. The first circumferential direction refers to the direction around the axis O, the first circumferential direction refers to one side in the circumferential direction, the second circumferential direction refers to the other side in the circumferential direction, and the radial direction refers to a direction along a straight line perpendicular to the axis O. However, the longitudinal section means a section including the axis O.

A feeding container 1 according to a first embodiment of the present invention shown in FIG. 1 has a case body 10. As shown in FIG. The case body 10 has a cylindrical shape extending along the axis O, and its upper end serves as a feeding opening 10a. In this embodiment, the feeding opening 10a is obliquely inclined with respect to a plane perpendicular to the axis O, but it may be perpendicular to the axis O.

The case body 10 can accommodate the solid content 2 therein. As the solid content 2, for example, cosmetics such as lipstick, lip balm, and stick eye shadow, medicines, stick glue, and the like that can be applied to the object to be applied can be adopted. In this embodiment, the solid content 2 is a substantially cylindrical lipstick. Note that the solid content 2 means a content that is hard enough to retain its shape, and includes content that is soft to a certain extent, such as a semi-kneaded content, for example. The solid contents stored in the case body 10 are exposed to the outside of the case body 10 at the feeding opening 10a.

It is also possible to configure the case body 10 to be removably fitted with an overcap 3 that covers the feeding opening 10a. In this embodiment, the overcap 3 has a cylindrical shape with a top including a peripheral wall 3a and a top wall 3b, and is configured to cover a predetermined area from the upper end of the case body 10 including the feeding opening 10a. ing. When attached to the case body 10, there is a vertical space between the top wall 3b of the overcap 3 and the dispensing port 10a, and the solid contents 2 are slightly protruded from the dispensing port 10a. Also, the overcap 3 can be attached to the case body 10 without the top wall portion 3b touching the solid contents 2, and the protruding portion of the solid contents 2 can be protected.

As shown in FIGS. 1 and 2, a feeding member 11 is disposed inside the case body 10 so as to be movable in the vertical direction while being prevented from rotating. The feeding member 11 is slidable in the vertical direction with respect to the inner circumferential surface of the case body 10.

The feeding member 11 includes a cylindrical peripheral wall portion 11a and an elastic valve 11b that is integrally provided at the upper end of the peripheral wall portion 11a. It can be slid. Further, a pair of rib-shaped guide rail portions 10b extending in the vertical direction are provided on the inner peripheral surface of the case body 10, and the feeding member 11 is provided with a groove extending in the vertical direction provided on the outer peripheral surface of the peripheral wall portion 11a. The pair of guided portions 11c are engaged with the corresponding guide rail portions 10b and guided in the vertical direction, so that they are prevented from rotating relative to the inner peripheral surface of the case body 10 in the vertical direction. It can be slid.

The elastic valve 11b is a so-called slit valve, which has a disk shape centered on the axis O, and has a cross-shaped slit 11d extending radially from the axis O, which is the central portion. Note that the slit 11d may have a Y shape, a letter shape, or any other shape as long as it extends in the radial direction from the center.

The feeding member 11 can be obtained by integral molding such as injection molding using rubber, elastomer, or soft synthetic resin such as polyethylene. Note that it is also possible to form the feeding member 11 by assembling a plurality of members.

The solid content 2 is housed in the case body 10 between the feeding opening 10a and the elastic valve 11b of the feeding member 11, and the bottom thereof is supported on the upper surface of the elastic valve 11b. By rising from the position shown in FIG. 1, the feeding member 11 can push up the solid content 2 stored inside the case body 10 and feed it out from the feeding opening 10a.

As shown in FIG. 1, a cylindrical shaft member 12 centered on an axis O is arranged below the feeding member 11. As shown in FIG. The shaft member 12 is prevented from coming off in the vertical direction by fitting into the circumferential wall portion 11a of the dispensing member 11 at an upper end portion having an outer circumferential surface facing the inner circumferential surface of the circumferential wall portion 11a of the dispensing member 11. The shaft member 12 also has a flange portion 12a having an upper surface facing the lower end surface of the peripheral wall portion 11a. The guide grooves 12b engage with the corresponding guide rail portions 10b and are guided in the vertical direction, so that they can slide vertically with respect to the inner circumferential surface of the case body 10 while being prevented from rotating. ing.

Note that instead of providing the flange portion 12a on the shaft member 12, the shaft member 12 is connected to the feeding member 11 through a spline portion, thereby preventing the shaft member 12 from rotating on the feeding member 11. The member 12 may be disposed with respect to the case body 10 so as to be movable in the vertical direction together with the feeding member 11 while being prevented from rotating.

A male thread 12c is provided on the outer peripheral surface of the shaft member 12 at a portion below the flange portion 12a over substantially the entire length. The male thread 12c is screwed to a threaded portion 40a provided on the operating member 13, which will be described later. A pair of outwardly facing engagement claws 12d are provided at the lower end of the shaft member 12 at intervals in the circumferential direction, thereby making it difficult for the shaft member 12 to slip upwardly from the threaded portion 40a. The outer circumferential surface of each engaging claw portion 12d at the lower end is inclined downwardly and radially inward, and is also elastically deformable radially inward. Therefore, the lower end portion of the shaft member 12 can be easily inserted into the radially inner side of the threaded portion 40a.

As shown in FIG. 1, an operating member 13 is connected to the case body 10 so as to be relatively rotatable in the circumferential direction. The operating member 13 has an annular grip portion 13 a disposed below the case body 10 and coaxially with the case body 10 . Note that the grip portion 13a has a double cylindrical shape with the same outer diameter as the case body 10.

In this embodiment, the operating member 13 has a cylindrical engagement tube portion 13b that protrudes from the upper end of the grip portion 13a toward the inside of the case body 10, and extends from the outer peripheral surface of the engagement tube portion 13b. The annular locking protrusion 13c provided to protrude radially outward is locked in the annular locking groove 10c provided on the inner circumferential surface of the case body 10, so that the case body 10 is It is held relatively rotatable in the direction.

In the state shown in FIG. 1 before the solid content 2 is fed out, the lower end portion of the shaft member 12 is located inside the grip portion 13a.

A ratchet mechanism section 20 is provided on the radially outer side of the shaft member 12 below the feeding member 11 . The ratchet mechanism section 20 operates to allow relative rotation of the operating member 13 with respect to the case body 10 in a first circumferential direction and to prevent it in a second circumferential direction.

As shown in FIGS. 1 and 4, in this embodiment, the ratchet mechanism section 20 includes a pair of claw sections 21 provided on the operating member 13 side and a gear section 22 provided on the case body 10 side. have. Here, FIG. 4 shows a cross section taken along line AA in FIG. 1, FIG. 5 shows a cross section taken along line BB in FIG. 1, and FIG. 6 shows a cross section taken along line CC in FIG. ing. In addition, in FIG. 4, FIG. 5, and FIG. 6, the shaft member 12 is shown by a two-dot chain line.

As shown in FIGS. 1, 3, and 4, each of the pair of claws 21 includes a leg 21a projecting from the upper end of the engaging cylinder 13b of the operating member 13, and a leg 21a that is supported by the leg 21a and is supported by the leg 21a. It integrally includes a curved piece 21b extending circumferentially from the portion 21a and a claw piece 21c extending radially outward from the tip of the curved piece 21b. The surface of each claw piece 21c facing away from the curved piece 21b is perpendicular to the circumferential direction. The pair of claw portions 21 are arranged such that the curved pieces 21b are elastically deformed in a direction that increases the degree of curvature using the leg portions 21a as a fulcrum, so that the claw pieces 21c are arranged on both sides in the radial direction between the shaft member 12 and the case body 10. It can be elastically deformed so as to be displaced.

On the other hand, as shown in FIG. 4, the gear portion 22 has a plurality of (eight) 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. A plurality of (eight) crossing surfaces 22b are provided. Each locking surface 22a engages with the claw piece 21c and locks the claw portion 21 when the operating member 13 rotates relative to the case body 10 in the second circumferential direction. is configured to prevent relative rotation in the second circumferential direction with respect to the case body 10. 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 operation member 13 rotates relative to the case body 10 in the first circumferential direction, the case body of the operation member 13 is 10 is configured to allow relative rotation in the first circumferential direction.

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 this embodiment creates sliding resistance between the operating member 13 and the case body 10 when the operating member 13 rotates relative to the case body 10 in the circumferential direction. It is possible to have a configuration including a sliding resistance applying section 30 that applies sliding resistance. The sliding resistance imparting section 30 is provided integrally with the operating member 13, as shown in FIG. The sliding resistance imparting portion 30 elastically contacts the inner circumferential surface of the case body 10 at a portion between the screw portion 40a and the ratchet mechanism portion 20, so that the operating member 13 is prevented from moving in the circumferential direction relative to the case body 10. It is configured to apply sliding resistance between the operating member 13 and the case body 10 when the operating member 13 and the case body 10 rotate relative to each other.

As shown in FIGS. 1, 3, and 5, the sliding resistance imparting section 30 of this embodiment includes a pair of pillars 31, a support 32, four elastic pieces 33, and four sliding protrusions 34. It is said that the structure is as follows.

More specifically, each of the pair of pillar portions 31 protrudes from the upper end of the engagement cylinder portion 13b between the shaft member 12 and the case body 10, and also functions as the pair of leg portions 21a. Note that the column portion 31 and the leg portion 21a may be provided separately. The upper ends of the pair of column parts 31 are integrally connected to a support body 32 located above the claw parts 21.

The support body 32 has a cylindrical shape coaxial with the engagement cylinder portion 13b, and is disposed between the shaft member 12 and the case body 10.

The four elastic pieces 33 are each in the shape of an elongated plate, and are arranged integrally at the upper end of the support body 32 at equal intervals in the circumferential direction. As shown in FIG. 3, each elastic piece 33 extends upward from the support body 32, and can be elastically deformed inward in the radial direction using the support body 32 as a fulcrum. Note that the intervals between the four elastic pieces 33 in the circumferential direction do not have to be equal. Moreover, the number of elastic pieces 33 can be changed in various ways.

Note that the column portion 31, the support body 32, and the elastic 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 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 piece 33 elastically deformed radially inward using the support 32 as a fulcrum. . In this way, the sliding protrusion 34 is in elastic contact with the inner peripheral surface of the case body 10, so that when the operating member 13 rotates relative to the case body 10 in the circumferential direction, the operating member 13 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 13 and the case body 10 is determined by conducting experiments in advance in consideration of 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 FIGS. 1 and 3, the operating member 13 has a threaded portion 40a formed as a female thread that is screwed to the male thread 12c of the shaft member 12. As shown in FIGS.

As shown in FIGS. 1, 3, and 6, in this embodiment, the threaded portion 40a is integrally provided on the inner circumferential surface of a threaded portion 40 that is integrally provided at the upper end portion of the operating member 13. . The screwing part 40 is configured to include four upper pillar parts 41, an upper support body 42, four projecting pieces 43, and four convex parts 44. The threaded part 40 is located between the ratchet mechanism part 20 and the feeding member 11.

More specifically, the four upper column parts 41 extend upward from the support body 32 between the shaft member 12 and the case body 10. The upper end of the upper column part 41 is integrally connected to an upper support body 42 located above the elastic piece 33. The four upper column parts 41 are each arranged between two circumferentially adjacent elastic pieces 33. That is, the four upper column parts 41 are arranged evenly in the circumferential direction. Note that the number and arrangement of the upper column portions 41 can be varied in accordance with the number and arrangement of the elastic pieces 33.

The upper support body 42 has a cylindrical shape coaxial with the support body 32. The upper support body 42 is arranged between the shaft member 12 and the case body 10.

The four projecting pieces 43 are each plate-shaped and are provided integrally at the upper end of the upper support body 42 at equal intervals in the circumferential direction. As shown in FIG. 3, each projecting piece 43 extends upward from the upper support 42, and is elastically deformable in both directions in the radial direction using the upper support 42 as a fulcrum. With such a configuration, when the shaft member 12 is inserted into the radially inner side of the threaded portion 40a, the protruding piece 43 is elastically deformed radially outward so as to expand the diameter of the threaded portion 40a. 12c can be inserted all the way to the back at once by passing over the threaded portion 40a. That is, the shaft member 12 and the threaded portion 40a can be assembled by a simple operation of sliding the shaft member 12 downward relative to the threaded portion 40a without rotating the shaft member 12 relative to the threaded portion 40a. . Furthermore, when forming the operating member 13, the projecting piece 43 elastically deforms outward in the radial direction, and is detached from the threaded part 40a along the axis O without rotating the mold corresponding to the threaded part 40a. Since the operating member 13 can be removed (that is, forcefully removed), the operating member 13 can be easily formed.

A threaded portion 40a is provided on the inner peripheral surface of each projecting piece 43. In this embodiment, the threaded portion 40a is provided only on a portion of the upper side of the projecting piece 43.

The convex portions 44 protrude radially outward from the outer circumferential surface of each protruding piece 43 . The convex portion 44 is configured to be slidable on the inner peripheral surface of the case body 10. Thereby, the strength of the screw connection between the threaded portion 40a and the male thread 12c can be increased, and the screw connection becomes difficult to come off. Note that the convex portion 44 is not an essential component. That is, the outer circumferential surface of the protruding piece 43 and the inner circumferential surface of the case body 10 come into contact with each other, thereby suppressing radially outward deformation of the protruding piece 43, and threading the threaded portion 40a and the male thread 12c together with high strength. For example, a convex portion may be provided on the inner circumferential surface of the case body 10, or a convex portion may not be provided on either the outer circumferential surface of the projecting piece 43 or the inner circumferential surface of the case body 10. You can.

In addition, the upper column part 41, the upper support body 42, and the four protrusions 43 are each arranged at intervals with respect to the inner circumferential surface of the case body 10.

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

As shown in FIG. 1, the feeding container 1 extends through the inside of the shaft member 12 to the bottom surface of the elastic valve 11b, and a hollow rod-shaped filling nozzle 16, which will be described later, can be inserted in order to penetrate the elastic valve 11b from the bottom side. It has a nozzle insertion path 14.

In this embodiment, the nozzle insertion path 14 extends through the inside of the operating member 13 and the shaft member 12 to the bottom surface of the elastic valve 11b. That is, the nozzle insertion path 14 is defined by the inner peripheral surface of the operating member 13, the inner peripheral surface of the shaft member 12, and the bottom surface of the elastic valve 11b.

Further, in this embodiment, the lower end of the nozzle insertion path 14 is closed by the circular label 15 affixed to the bottom surface of the grip portion 13a of the operating member 13.

As shown in FIG. 7, the dispensing container 1 of this embodiment having the above-mentioned configuration is constructed by holding the case body 10 with one hand while removing the overcap 3 from the case body 10 with the other hand. By rotating the operating member 13 relative to the case body 10 in the first circumferential direction by grasping the gripping portion 13a of the operating member 13 and rotating the operating member 13 in the first circumferential direction, the solid contents 2 can be moved into the case. It can be fed out from the feeding opening 10a of the body 10.

That is, when the operating member 13 is rotated relative to the case body 10 in the first circumferential direction, the threaded portion 40a, which is a part of the operating member 13, is rotated relative to the case body 10 in the first circumferential direction. The shaft member 12 equipped with a male thread 12c that is screwed to the threaded portion 40a is prevented from rotating by the case body 10, so when the operating member 13 is rotated relative to the case body 10 in the first circumferential direction, the threaded portion 40a and the male thread 12c, the shaft member 12 and the feeding member 11 rise together with respect to the case body 10. As a result, the solid contents 2 are pushed up by the rising feeding member 11 and fed out of the case body 10 from the feeding opening 10a. The amount by which the solid content 2 is fed out (the amount of protrusion) from the case body 10 can be adjusted by the amount by which the operating member 13 is relatively rotated. Therefore, by rotating the operating member 13 relative to the case body 10 by a desired amount in the first circumferential direction, a desired amount of the solid contents 2 is dispensed from the dispensing port 10a of the case body 10 and used. be able to.

On the other hand, when the operating member 13 is rotated relative to the case body 10 in the second circumferential direction opposite to when the solid contents 2 are fed out, the ratchet mechanism 20 prevents the relative rotation. Therefore, even if the operating member 13 is suddenly operated in the direction of relative rotation in the second circumferential direction with respect to the case body 10, the feeding member 11 supporting the lower end portion of the solid content 2 will not descend. This prevents the solid contents 2 from being drawn into the case body 10. Therefore, even if a solid content 2 such as a relatively soft lipstick is stored, the hardness of which is difficult to insert into the case body 10, the operating member 13 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.

As shown in FIGS. 8 to 11, the dispensing container 1 configured as described above is capable of back-filling in which the solid contents 2 are filled from the bottom side of the dispensing member 11. Back filling can be performed, for example, in the following manner.

First, the case body 10, the feeding member 11, the shaft member 12, and the operating member 13 are assembled so as to be in the state shown in FIG. Then, a cylindrical capsule 17 with one end closed is attached to the feeding opening 10a. The capsule 17 has a cylindrical wall 17a that is in close contact with the outer peripheral surface of the case body 10 at the feeding opening 10a, and an end wall 17b that closes one end of the cylindrical wall 17a. Note that a vertical groove 17c extending from the other end of the cylindrical wall 17a toward one end is provided at one location in the circumferential direction on the inner peripheral surface of the cylindrical wall 17a in order to facilitate removal of the capsule 17 from the feeding port 10a. There is. The end wall 17b has an inner surface that follows the shape of the tip to be provided to the solid content 2.

Next, the cylindrical filling nozzle 16 is inserted into the dispensing container 1 in an inverted position with the dispensing opening 10a facing vertically downward. At this time, the tip 16a of the filling nozzle 16, which can discharge the heated and fluid solid content 2, is arranged vertically downward, and the tip 16a is coaxial with the axis O. It is inserted into the nozzle insertion path 14 from the bottom, and the tip 16a pushes open the slit 11d of the elastic valve 11b. Then, as shown in FIG. 8, the solid content 2 is discharged with the tip portion 16a located between the elastic valve 11b and the delivery port 10a. At this time, as the solid content 2 is filled into the case body 10, the air inside the case body 10 is moved between the slit 11d pushed open and the outer peripheral surface of the filling nozzle 16, as shown in FIG. It is smoothly discharged through the gap G formed in the .

When filling of the solid content 2 is completed, the filling nozzle 16 is pulled out from the elastic valve 11b, as shown in FIG. Note that at this time, the filling space between the elastic valve 11b and the feeding port 10a may not be completely filled with the solid content 2, and even in such a case, the filling space between the elastic valve 11b and the feeding port 10a may not be completely filled with the solid content 2. There is no problem in drawing out the solid content 2 and using it. The solid content 2 solidifies as it cools, and the tip of the solid content 2 is formed into a shape that follows the inner surface of the end wall 17b of the capsule 17.

When the filling nozzle 16 is extracted from the dispensing container 1, the dispensing container 1 is turned upside down to take an upright position, the capsule 17 is removed from the dispensing opening 10a, and the overcap 3 is attached to cover the dispensing opening 10a. . Further, the label 15 is attached to the bottom surface of the grip portion 13a, and the nozzle insertion path 14 is closed. Note that the posture of the dispensing container 1 during and after filling with the solid content 2 is not limited to the above-described one, and the dispensing container 1 in an upright position may be filled with the solid content 2, for example.
