Hereinafter, the present invention will be described in more detail with reference to the drawings.

As shown in FIG. 1, the feeding container 1 according to the present embodiment includes a main body 10, an outer cylinder 20, an inner cylinder 30, a transmission cylinder 40, a movable cylinder 50, an inner plate 60, and the like. A cap 70 and a sliding ring 80 are provided. Here, the axis C coincides with the central axis of the feeding container 1 and is the rotation axis of the outer cylinder 20 with respect to the main body 10. Further, the solid content L held in the storage space S of the feeding container 1 can be, for example, a cosmetic such as lipstick, lip balm, stick eye shadow, a drug, or glue, but is not particularly limited and is applied. Various things that can be applied to the object can be adopted. The solid content L means a content having a hardness sufficient to retain its shape, and includes a content having a certain degree of softness such as a semi-kneaded material.

The main body portion 10 is composed of a base member 11 and an operation cylinder portion 12 fixed to the base member 11. In this example, the operation cylinder portion 12 is fixed to the outer peripheral edge portion of the bottom wall 13 of the base member 11 by undercut engagement. As a result, the operation cylinder portion 12 rotates together with the base member 11. The method of fixing the operation cylinder portion 12 to the bottom wall 13 may be ultrasonic bonding or welding.

As shown in FIG. 2, the base member 11 stands on the disc-shaped bottom wall 13, the shaft portion 14 erected at the center of the bottom wall 13, and the bottom wall 13 on the radial outer side of the shaft portion 14. It has a tubular wall 15 provided. The cylinder wall 15 is located between the shaft portion 14 and the operation cylinder portion 12. A male screw 15a is provided on the outer peripheral surface of the cylinder wall 15. The male screw 15a can be, for example, a double-threaded screw, but is not limited thereto. Further, below the male screw 15a, a large diameter portion 15e having a large diameter is provided on the outer peripheral surface of the cylinder wall 15.

Further, in this example, the base member 11 of the main body 10 is provided with a leaf spring portion 16 (upward urging portion) erected on the bottom wall 13 on the radial outer side of the shaft portion 14. The leaf spring portions 16 are arranged to face each other at two locations in the circumferential direction with the axis C interposed therebetween, and are arranged in the openings 15b provided in the cylinder wall 15.

The shaft portion 14 has a shape corresponding to the through hole 51 of the movable cylinder 50. In this example, as shown in FIG. 3, six vertical ribs 14a are provided, each of which enters the vertical groove 51a of the through hole 51. The six vertical ribs 14a are evenly arranged in the circumferential direction around the axis C of the shaft portion 14, and each vertical rib 14a extends parallel to the axis C. The shaft portion 14 extends linearly along the axis C and has the same cross section over the entire height. The lower end of the operation cylinder 12 is fixed to the outer peripheral edge of the bottom wall 13. In this example, a knurled portion 13a and an engaging protrusion 13b are provided on the outer peripheral surface of the bottom wall 13. The knurled portion 13a suppresses the rotation of the operating cylinder portion 12 with respect to the bottom wall 13, and the engaging projection 13b retains and holds the operating cylinder portion 12 with respect to the bottom wall 13.

As shown in FIG. 4, the operation cylinder portion 12 has a large diameter portion 12a on the lower side and a small diameter portion 12c connected above the large diameter portion 12a via a step portion 12b. The diameter of the outer peripheral surface of the small diameter portion 12c is smaller than that of the large diameter portion 12a. The operation cylinder portion 12 is arranged on the outer side in the radial direction of the outer cylinder body 20. A fitting convex portion 12d for fitting and holding the cap 70 is provided on the outer peripheral surface of the small diameter portion 12c of the operation cylinder portion 12. A knurled groove 12f corresponding to the knurled portion 13a of the bottom wall 13 and an engaged protrusion 12g corresponding to the engaging protrusion 13b are provided on the lower inner peripheral surface of the operation cylinder portion 12.

As shown in FIG. 5, the outer cylinder 20 has a cylindrical shape and has an upper end portion 20a having a shape cut obliquely with respect to the axis C and a lower end portion 20b perpendicular to the axis C. The outer cylinder 20 of this example is made of metal such as aluminum. An annular flange 21 extending radially outward is provided on the lower end portion 20b of the outer cylinder 20. Further, on the inner peripheral surface of the outer cylinder 20, a screw convex portion 22 (female screw) that screw-engages with the male screw 15a of the cylinder wall 15 in the main body 10 is provided. The screw convex portion 22 is provided only on a part of the outer cylinder 20 in the circumferential direction. In this example, the two screw convex portions 22 are arranged so as to face each other with the axis C interposed therebetween.

Further, an inward convex portion 23 and an upper convex portion 24 are provided on the inner peripheral surface of the outer cylinder 20. The inward convex portion 23 is located above the screwed convex portion 22, and the upper convex portion 24 is located above the inward convex portion 23. The inward convex portion 23 and the upper convex portion 24 have a vertical rib shape extending parallel to the axis C, but the shape is not limited to this and the shape can be changed as appropriate. In this example, the inward convex portions 23 are evenly arranged at two locations in the circumferential direction of the outer cylinder 20, and the upper convex portions 24 are evenly arranged at two locations in the circumferential direction of the outer cylinder 20. The screw convex portion 22, the inward convex portion 23, and the upper convex portion 24 are not limited to the illustrated examples, and the axial position, the circumferential position, the number, and each shape can be appropriately changed.

Note that FIG. 12 shows an outer cylinder 120 as a modified example. The outer cylinder 120 is made of synthetic resin. By properly using the metal outer cylinder 20 and the synthetic resin outer cylinder 120 in the feeding container 1, the appearance and the like can be differentiated. For example, when the metal outer cylinder 20 is used, the feeding container 1 can be given a high-class feeling. The outer cylinder 120 shown in FIG. 12 is formed with elastic pieces 25a, 26a, 27a that can be elastically deformed by the U-shaped notch grooves 25, 26, 27. The screwed convex portion 22, the inward convex portion 23, and the upper convex portion 24 are provided on the inner surfaces of the elastic pieces 25a, 26a, and 27a, respectively. Since the elastic pieces 25a, 26a, and 27a are elastically deformed outward in the radial direction of the outer cylinder 120, the work of arranging the outer cylinder 120 outside the inner cylinder 30 and the transmission cylinder 40 becomes easy. The elastic pieces 25a, 26a, and 27a are elastically deformed outward in the radial direction of the outer cylinder 120, so that the outer cylinder 120 can be easily removed from the mold after injection molding of the outer cylinder 120. That is, by providing the elastic pieces 25a, 26a, 27a, the outer cylinder 120 can be easily formed.

As shown in FIG. 1, the inner cylinder 30 is held inside the outer cylinder 20 in the radial direction, and together with the inner plate 60, partitions the storage space S for the solid contents L. As shown in FIG. 6, the inner cylinder 30 has a cylindrical shape, and like the outer cylinder 20, the upper end portion 30a cut diagonally with respect to the axis C and the lower end portion 30b perpendicular to the axis C. Has. Further, the inner cylinder body 30 has an inner cylinder main body 31 and a small diameter portion 32 which is connected to the lower side of the inner cylinder main body 31 and whose outer peripheral surface diameter is smaller than that of the inner cylinder main body 31. A vertical groove-shaped recess 33 corresponding to the upper convex portion 24 of the outer cylinder 20 is provided on the outer peripheral surface of the inner cylinder main body 31. The vertical groove-shaped recess 33 is formed in a notch shape that opens at the lower end surface of the inner cylinder main body 31. The recesses 33 correspond to the upper convex portion 24 of the outer cylinder 20 and are evenly arranged at two locations in the circumferential direction of the inner cylinder 30. A claw portion 34 that engages with the transmission cylinder 40 is provided on the inner peripheral surface of the small diameter portion 32. The small diameter portion 32 of this example is composed of two wall portions arranged so as to face each other with the axis C interposed therebetween, but the present invention is not limited to this, and may have a tubular shape that is not intermittent in the circumferential direction, or may be in the circumferential direction. It may be composed of three or more wall portions formed at intervals.

A rotation suppressing portion for suppressing relative rotation is provided between the outer cylinder 20 and the inner cylinder 30. As a result, the outer cylinder 20 and the inner cylinder 30 rotate together. In this example, the rotation suppressing portion between the outer cylinder 20 and the inner cylinder 30 is formed by an upper convex portion 24 provided on the inner peripheral surface of the outer cylinder 20 and a concave portion 33 provided on the inner cylinder 30. It is configured. That is, the upper convex portion 24 of the outer cylinder 20 enters the concave portion 33 of the inner cylinder 30, so that the relative rotation between the outer cylinder 20 and the inner cylinder 30 is suppressed. The outer cylinder 20 is arranged so as to be vertically movable with respect to the inner cylinder 30 within a range until the upper convex portion 24 of the outer cylinder 20 reaches the upper end of the concave portion 33.

As shown in FIG. 7, the transmission cylinder 40 has a cylindrical shape and is held inside the inner cylinder 30 in the radial direction and outside the movable cylinder 50 in the radial direction. The lower portion of the transmission cylinder 40 is arranged inside the cylinder wall 15 of the main body 10 in the radial direction. Further, the transmission cylinder 40 is arranged below the middle plate 60.

On the inner peripheral surface of the transmission cylinder 40, a female screw 41 of a reverse screw type (opposite to the screwed convex portion 22 of the outer cylinder 20) is provided. The female screw 41 is provided only on the upper portion of the transmission cylinder 40. In this example, a notch 42 is formed on the upper portion of the transmission cylinder 40 so as to face each other with the axis C interposed therebetween, and the female screw 41 is the inner circumference of the movable piece 43 partitioned by the notch 42. It is provided on the surface. The movable piece 43 constitutes an elastic piece that can be elastically deformed inward and outward in the radial direction.

On the outer peripheral surface of the transmission cylinder 40, an annular engaging groove 44, an outward convex portion 45 (rotation restricting portion) below the engaging groove 44, and a claw portion 46 below the outward convex portion 45 are formed. It is provided. The engaging groove 44 is provided at an intermediate portion in the axial direction (vertical direction) along the axis C. The lower side surface of the engaging groove 44 is arranged below the lower end portion of the inner cylinder body 30 and can be engaged with the lower end portion of the inner cylinder body 30 in the vertical direction. The claw portion 46 engages with the lower end of the tubular wall 15 provided with the opening 15b from below. As a result, the upward movement of the transmission cylinder 40 with respect to the main body 10 (cylinder wall 15) is suppressed.

The outward convex portions 45 are evenly arranged at four locations in the circumferential direction of the transmission cylinder 40. An inclined surface 45a extending diagonally toward one side in the circumferential direction of the transmission cylinder 40 is formed on the upper portion of the outward convex portion 45. By providing such an inclined surface 45a, it is possible to prevent unnecessary interference with the outer cylinder 20 that moves up and down while rotating relative to the transmission cylinder 40, and the movement of the outer cylinder 20 is further increased. Can be smooth.

The outward convex portion 45 and the inward convex portion 23 form a rotation restricting portion. When the outer cylinder 20 is in the upper position, the outward convex portion 45 and the inward convex portion 23 do not engage with each other, so that the transmission cylinder 40 is allowed to rotate with respect to the outer cylinder 20. On the other hand, when the outer cylinder 20 is in the lower position, the outward convex portion 45 and the inward convex portion 23 are engaged with each other, and the rotation of the transmission cylinder 40 with respect to the outer cylinder 20 is suppressed. .. As a result, the transmission cylinder 40 is allowed to rotate with respect to the outer cylinder 20 when the outer cylinder 20 is in the upper position, and the transmission cylinder 40 is allowed to rotate with respect to the outer cylinder 20 when the outer cylinder 20 is in the lower position. Is suppressed. The rotation control unit is provided between the outer cylinder 20 and the transmission cylinder 40, and allows the transmission cylinder 40 to rotate with respect to the outer cylinder 20 when the outer cylinder 20 is in the upper position, and is outside. It suffices as long as it suppresses the rotation of the transmission cylinder 40 with respect to the outer cylinder 20 when the cylinder 20 is in the lower position, and is not limited to the inward convex portion 23 and the outward convex portion 45 of this example.

A slit 47 is formed in the lower portion of the transmission cylinder 40. The slit 47 extends linearly in parallel with the axis C and opens at the lower end of the transmission cylinder 40. Further, the slits 47 are located on the lower side of the outward convex portion 45, and are evenly arranged at two locations in the circumferential direction of the transmission cylinder 40. The upper side surface of the engaging groove 44 constitutes an annular engaged portion 48.

As shown in FIG. 8, the movable cylinder 50 has a cylindrical shape and is arranged on the radial outside of the shaft portion 14 of the main body 10 and on the radial inside of the transmission cylinder 40. The movable cylinder 50 can move up and down with respect to the shaft portion 14 of the main body portion 10, and is held in a state in which rotation with respect to the shaft portion 14 is suppressed.

A through hole 51 is formed in the center of the movable cylinder 50. The through hole 51 has a vertical groove 51a that suppresses the relative rotation of the movable cylinder 50 and the shaft portion 14. In this example, the six vertical grooves 51a are evenly arranged in the circumferential direction of the movable cylinder 50. The shapes of the through hole 51 and the shaft portion 14 are not particularly limited as long as the relative rotation with respect to the shaft portion 14 can be suppressed. That is, for example, the through hole 51 and the shaft portion 14 may have a non-circular cross section such as a polygon.

A reverse screw type male screw 52 (opposite to the male screw 15a of the cylinder wall 15 of the main body 10) is provided on the outer peripheral surface of the movable cylinder 50. The male screw 52 is screw-engaged with the female screw 41 of the transmission cylinder 40, and has a pitch smaller than that of the male screw 15a of the cylinder wall 15 of the main body 10. By reducing the pitch of the male screw 52 and the female screw 41, it becomes easy to finely adjust the carry-up amount of the solid content L. For example, the pitch of the male screw 15a of the cylinder wall 15 can be set to 3 mm, and the pitch of the male screw 52 of the movable cylinder 50 can be set to 0.5 mm. Further, the male screw 52 can be, for example, a single-threaded screw, but the screw 52 is not limited to this.

A holding convex portion 53 for holding the middle plate 60 is provided at the upper end portion of the movable cylinder 50. An annular small diameter portion 54 is formed below the holding convex portion 53. The diameter of the outer surface of the small diameter portion 54 is smaller than that of other portions of the movable cylinder 50.

As shown in FIG. 1, the inner plate 60 is arranged so as to be vertically movable with respect to the inner cylinder 30 inside the inner cylinder 30 in the radial direction. A movable cylinder 50 is arranged below the middle plate 60, and the middle plate 60 is arranged so as to be pushed upward by the movable cylinder 50. As shown in FIG. 9, the middle plate 60 has a disc-shaped top wall 61, an annular outer wall 62 hanging from the top wall 61, and an inner wall 63 located radially inside the outer peripheral wall. A claw portion 64 is formed on the inner peripheral surface of the inner wall 63.

In the middle plate 60, a holding convex portion 53 and a small diameter portion 54 of the movable cylinder 50 are arranged inside the inner wall 63. By engaging the claw portion 64 and the holding convex portion 53, the middle plate 60 is held in place with respect to the movable cylinder 50. The middle plate 60 of this example is held so as to be vertically movable within a predetermined range with respect to the movable cylinder 50. In the state shown in FIG. 1, the claw portion 64 and the holding convex portion 53 are arranged with a gap G in the axial direction. As a result, even when the movable cylinder 50 is lowered, the middle plate 60 is not lowered until the claw portion 64 and the holding convex portion 53 come into contact with each other.

The cap 70 has a climax cylindrical shape, and can be detachably attached to the small diameter portion of the operation cylinder portion 12 in the main body portion 10 to cover the solid content L, the outer cylinder 20 and the like.

As shown in FIG. 10, the sliding ring 80 is a crank-shaped spring portion 83 (lower) provided between the annular upper ring 81, the annular lower ring 82, and the upper ring 81 and the lower ring 82. It has an urging part). An annular convex portion 81a is provided on the outer peripheral surface of the upper ring 81. The convex portion 81a engages with the convex portion 12e on the inner peripheral surface of the operation cylinder portion 12. The upper ring 81 and the lower ring 82 of the sliding ring 80 make it easier to stabilize the radial position of the outer cylinder 20 with respect to the operation cylinder portion 12. As a result, the outer cylinder 20 moves up and down more smoothly, and the operation becomes easier to stabilize. The spring portion 83 has a horizontal portion 83a perpendicular to the axis C and vertical portions 83b and 83c connected to both ends of the horizontal portion 83a, respectively, and the vertical portions are connected to the upper ring 81 and the lower ring 82, respectively. In this example, the two spring portions 83 are evenly arranged in the circumferential direction, but the shape, number, and arrangement of the spring portions 83 can be changed as appropriate.

The sliding ring 80 is arranged on the radial inside of the large diameter portion 12a of the operation cylinder portion 12 and on the radial outside of the outer cylinder 20. Further, the sliding ring 80 is arranged above the flange 21 of the outer cylinder body 20 and below the inner surface step portion 12h of the operation cylinder portion 12. The sliding ring 80 is configured to urge the outer cylinder 20 downward when the outer cylinder 20 rises with respect to the operation cylinder 12 of the main body 10. As a result, when the outer cylinder 20 rises to the maximum with respect to the main body 10 and the screw convex portion 22 is disengaged from the male screw 15a, the screw convex portion 22 engages with the male screw 15a. The outer cylinder 20 is pushed down by the spring portion 83 of the sliding ring 80. As a result, if the operation cylinder portion 12 is continuously rotated in the direction in which the outer cylinder 20 is raised, the outer cylinder 20 repeatedly moves up and down in the upper region.

Here, the leaf spring portion 16 is configured to urge the outer cylinder body 20 upward when the outer cylinder body 20 descends with respect to the main body portion 10. As a result, when the outer cylinder 20 is lowered to the maximum with respect to the main body 10 and the screw convex portion 22 is disengaged from the male screw 15a, the screw convex portion 22 is engaged with the male screw 15a. Until then, the leaf spring portion 16 pushes up the outer cylinder 20. As a result, when the operation cylinder portion 12 is continuously rotated in the direction in which the outer cylinder 20 is lowered, the outer cylinder 20 repeatedly moves up and down in the lower region.

Note that FIG. 11 shows a modified example of the main body 10. In the example shown in FIG. 11, instead of providing the sliding ring 80 and the leaf spring portion 16, return paths 15c and 15d are provided at the end portions on both sides of the male screw 15a, respectively. As a result, when the outer cylinder 20 rises to the maximum with respect to the main body 10, the screwed convex portion 22 moves along the return path 15c, so that the same as when the sliding ring 80 is provided. The outer cylinder 20 temporarily lowers, and after the screwed convex portion 22 passes through the return path 15c, it rises again. That is, when the operation cylinder portion 12 is continuously rotated in the direction in which the outer cylinder 20 is raised, the outer cylinder 20 repeatedly moves up and down in the upper region. Further, when the outer cylinder 20 is lowered to the maximum with respect to the main body 10, the screw convex portion 22 moves along the return path 15d, so that the outer cylinder 20 is provided as in the case where the leaf spring portion 16 is provided. The tubular body 20 temporarily rises, and after the screwed convex portion 22 passes through the return path 15d, it descends again. That is, when the operation cylinder portion 12 is continuously rotated in the direction in which the outer cylinder 20 is lowered, the outer cylinder 20 repeatedly moves up and down in the lower region.

An example of a setting method (assembly method) of each member constituting the feeding container 1 will be described below. First, the transmission cylinder 40 is attached to the base member 11. At that time, the shaft portion 14 of the base member 11 is passed through the transmission cylinder 40, and the lower portion of the transmission cylinder 40 is inserted into the inside of the cylinder wall 15. In this example, since the slit 47 is formed in the lower part of the transmission cylinder 40, the lower end side of the transmission cylinder 40 is easily elastically deformed inward in the radial direction, and the lower part of the transmission cylinder 40 is easily deformed. It can be inserted inside the wall 15. A chamfered portion is provided at the circumferential end of the transmission cylinder 40 so that the claws 46 of the transmission cylinder 40 do not interfere with each other when the lower end side of the transmission cylinder 40 is elastically deformed inward in the radial direction. It is preferable to keep it. Further, as shown in FIG. 1, in the state where the assembly is completed, the lower portion of the transmission cylinder 40 is sandwiched between the movable cylinder 50 and the cylinder wall 15 from both the inner and outer sides in the radial direction and is less likely to be deformed. The claw portion 46 of the tubular body 40 firmly engages with the tubular wall 15.

Next, the movable cylinder 50 is attached to the base member 11. The movable cylinder 50 is inserted into the transmission cylinder 40 while passing the shaft portion 14 of the base member 11 through the movable cylinder 50. In this example, a notch 42 is formed in the upper part of the transmission cylinder 40, and the movable piece 43 having the female screw 41 elastically deforms outward in the radial direction, so that the movable cylinder 50 can be easily moved to the inside of the transmission cylinder 40. Can be plugged into.

Next, the inner cylinder 30 to which the outer cylinder 20 is attached to the outside is attached to the outside of the transmission cylinder 40. When the claw portion 34 of the inner cylinder body 30 engages with the engaged portion 48 of the transmission cylinder body 40, the inner cylinder body 30 is held in place with respect to the transmission cylinder body 40. When setting the inner cylinder 30 inside the outer cylinder 20, the inner cylinder is opened through the opening of the upper end 20a of the outer cylinder 20 while keeping the positions of the upper convex portion 24 and the concave portion 33 in the circumferential direction. Insert the body 30.

Next, the middle plate 60 is inserted into the inner cylinder body 30, and the middle plate 60 is attached to the upper end of the movable cylinder 50. Then, the operation cylinder portion 12 to which the sliding ring 80 is attached inside is fixed to the bottom wall 13 of the base member 11 by undercut engagement or the like. Further, the accommodation space S is filled with the solid content L, and finally, the cap 70 is attached to the operation cylinder portion 12, so that the state shown in FIG. 1 is obtained. As described above, the feeding container 1 of the present embodiment can be easily assembled. The order of assembling the feeding container 1 is not limited to the above method, and can be changed as appropriate.

The method of using the feeding container 1 will be described below. When feeding out the solid content L from the feeding container 1, the cap 70 is removed from the state shown in FIG. 1, the outer cylinder 20 is gripped, and the operation cylinder portion 12 (main body portion 10) is moved in one direction (feeding direction). Rotate to. When the operation cylinder portion 12 is rotated with respect to the outer cylinder body 20, the cylinder wall 15 and the shaft portion 14 rotate together with the operation cylinder portion 12, and the movable cylinder 50 rotates together with the shaft portion 14. Further, when the main body 10 rotates, the outer cylinder 20 becomes the operation cylinder 12 and the main body 10 due to the engagement (screw) between the male screw 15a of the cylinder wall 15 and the screwed convex portion 22 of the outer cylinder 20. On the other hand, it moves downward. When the outer cylinder 20 descends to the lower position, the inward convex portion 23 as the rotation restricting portion and the outward convex portion 45 engage with each other, so that the rotation of the transmission cylinder 40 with respect to the outer cylinder 20 is suppressed. To. Therefore, the movable cylinder 50 that rotates together with the operation cylinder portion 12 of the main body portion 10 rotates with respect to the transmission cylinder 40, and the movable cylinder 50 rises with respect to the transmission cylinder 40 and the main body 10. As a result, the middle plate 60 and the solid content L rise together with the movable cylinder 50, and the solid content L is fed out from the upper end portion 30a of the inner cylinder body 30 and the upper end portion 20a of the outer cylinder body 20. As described above, when the solid content L is fed out in the feeding container 1 of this example, the solid content L starts to rise after the outer cylinder 20 is lowered by a predetermined distance.

More specifically, in the feeding container 1 of this example, when the cap 70 is removed from the state shown in FIG. 1 and the operation cylinder portion 12 is first rotated once with respect to the outer cylinder body 20, the outer cylinder body 20 becomes the main body portion. It descends 3 mm with respect to 10 to reach the lower position. After that, when the operation cylinder portion 12 is further rotated in the same direction, the engagement between the male screw 15a of the main body portion 10 and the screw convex portion 22 of the outer cylinder body 20 is temporarily released, and the outer cylinder body 20 is a leaf spring. It is pushed up by the portion 16 and rises by 1.5 mm, and the male screw 15a and the screw convex portion 22 are engaged again. Further, when the operation cylinder portion 12 is rotated in the same direction, the outer cylinder portion 20 is lowered by 1.5 mm with respect to the main body portion 10 and is raised by 1.5 mm again, and so on. When the outer cylinder 20 repeatedly moves up and down in the lower region by rotating the operation cylinder portion 12 in the feeding direction in this way, the female screw 41 of the transmission cylinder 40 and the male screw 52 of the movable cylinder 50 The movable cylinder 50 continues to move upward together with the inner plate 60 and the solid content L.

Further, after the solid content L is fed out and applied to the object to be coated, when the operation cylinder portion 12 is rotated in the lowering direction opposite to the feeding direction, the male screw 15a of the cylinder wall 15 and the outer cylinder 20 are screwed together. By engaging with the convex portion 22, the outer cylinder body 20 rises with respect to the operation cylinder portion 12 and the main body portion 10. For example, in this example, the outer cylinder 20 rises 0.75 mm at 1/4 rotation. In the process of raising the outer cylinder 20 with respect to the main body 10 in this way, while the inward convex portion 23 and the outward convex portion 45 are engaged with each other, the transmission cylinder 40 rotates with respect to the outer cylinder 20. Is suppressed, so that the movable cylinder 50 descends with respect to the transmission cylinder 40 and the main body 10. However, since a gap G is provided between the claw portion 64 of the middle plate 60 and the holding convex portion 53 of the movable cylinder 50, when the movable cylinder 50 descends with respect to the main body portion 10, the claw portion 64 and the claw portion 64 The middle plate 60 does not descend until it comes into contact with the holding convex portion 53. That is, even if the operation cylinder portion 12 is rotated in the lowering direction, the middle plate 60 and the solid content L are not immediately lowered.

Then, when the operation cylinder portion 12 is further rotated in the downward direction, the outer cylinder body 20 rises to the upper position, and the engagement between the inward convex portion 23 and the outward convex portion 45 is released. For example, in this example, the outer cylinder 20 is further raised by 2.25 mm in 3/4 rotation after the 1/4 rotation. As a result, the rotation of the transmission cylinder 40 with respect to the outer cylinder 20 is allowed. That is, the transmission cylinder 40 idles with respect to the outer cylinder 20, and the movable cylinder 50 and the transmission cylinder 40 do not rotate relatively. Therefore, even if the operation cylinder portion 12 is further rotated in the downward direction, The movable cylinder 50 does not descend. As a result, even if the operation cylinder portion 12 is rotated in the lowering direction, the middle plate 60 and the solid content L are not lowered and are stopped at a constant height. In this example, by rotating the operation cylinder portion 12 in the lowering direction by 1/4 rotation and 3/4 rotation, the outer cylinder portion 20 is raised by 3 mm in total, and then the operation cylinder portion 12 is further moved in the lowering direction. When rotated, the outer cylinder 20 repeatedly lowers by 1.5 mm by being pushed down by the spring portion 83 of the sliding ring 80 and rises by 1.5 mm by engaging the male screw 15a and the screw convex portion 22. .. When the outer cylinder 20 moves up and down by rotating the operation cylinder portion 12 in the downward direction in this way, the transmission cylinder 40 idles with respect to the outer cylinder 20, and the movable cylinder 50 and the transmission cylinder 40 Since and do not rotate relatively, the middle plate 60 and the solid content L are in a stopped state.

As described above, in the feeding container 1 of the present embodiment, when the outer cylinder 20 is in the upper position, the movable cylinder 50 does not move up and down, and when the outer cylinder 20 is in the lower position. Is configured such that the movable cylinder 50 moves up and down. As a result, when feeding out the solid content L, it is necessary to rotate the operation cylinder portion 12 until the outer cylinder 20 is in the lower position, so that the solid content L becomes large with a slight rotation operation. It will not be drawn out. Further, even if the operation cylinder portion 12 is rotated in the lowering direction after use, the solid content L cannot be lowered when the outer cylinder 20 rises to the upper position. That is, the solid content L is gradually unwound during use, and can be prevented from being unintentionally unwound after use. As a result, even if the solid content L is relatively soft, the solid content L is less likely to be broken or damaged during use.

Further, in the feeding container 1 of the present embodiment, the middle plate 60 is configured to be movable in the axial direction within a predetermined range with respect to the movable cylinder 50, so that the solid content L is further lowered. It becomes difficult. As a result, the effect of suppressing damage to the solid content L can be enhanced.

Further, in the feeding container 1 of the present embodiment, when the outer cylinder 20 is lowered to the maximum and the screw engagement between the main body 10 and the outer cylinder 20 is temporarily released, the outer cylinder 20 is removed. The tubular body 20 is configured to move upward by the upward urging portion (leaf spring portion 16). With such a configuration, since the main body portion 10 and the outer cylinder body 20 are securely screw-engaged, the stability of the operation of the outer cylinder body 20 accompanying the rotation of the operation cylinder portion 12 can be improved. Further, according to this configuration, since the outer cylinder 20 repeatedly moves up and down in the process of feeding out the solid content L, it becomes easy to finely adjust the feeding amount of the solid content L, and the solid content L is damaged. The effect of suppressing can be enhanced.

Further, in the feeding container 1 of the present embodiment, the number of parts can be reduced by integrally connecting the leaf spring portion 16 to the bottom wall 13 of the base member 11 (integral molding).

Further, in the feeding container 1 of the present embodiment, when the outer cylinder 20 is raised to the maximum and the screw engagement between the main body 10 and the outer cylinder 20 is temporarily released, the outer cylinder 20 is removed. The tubular body 20 is configured to move downward by the downward urging portion (spring portion 83). With such a configuration, since the main body portion 10 and the outer cylinder body 20 are securely screw-engaged, the stability of the operation of the outer cylinder body 20 accompanying the rotation of the operation cylinder portion 12 can be improved.

Further, in the feeding container 1 of the present embodiment, the upper ring 81 and the lower ring 82 for stabilizing the radial position of the outer cylinder 20 with respect to the operation cylinder portion 12 and the outer cylinder 20 are urged downward. The number of parts can be reduced by forming (integrally molding) the spring portion 83 for forming the spring portion 83 as an integral body.

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist thereof.

For example, in the above embodiment, the cap 70 is held by the main body 10 by undercut engagement, but it may be held by screw engagement. Further, the base member 11 and the operation cylinder portion 12 constituting the main body portion 10, the outer cylinder body 20, the inner cylinder body 30, the transmission cylinder body 40, the movable cylinder 50, the middle plate 60, the cap 70, and the sliding ring 80 are Each can be made of synthetic resin, but not limited to this, various materials can be adopted.
