Jitsukaisho 51-47745

In the configuration of Patent Document 1, there is room for improvement in the structure for restricting the relative rotation of each member in that the size of the feeding container in the vertical direction is made smaller.

The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a feeding container capable of reducing the total length in the vertical direction while ensuring the stroke amount of the inner dish portion.

In order to solve the above problem, the feeding container according to one aspect of the present invention extends upward from the inner plate portion for holding the contents, the operation cylinder portion, and the operation cylinder portion, and extends the middle plate portion upward. A sleeve that surrounds from the outside in the radial direction, a rotation restricting shaft that is located inside the sleeve in the radial direction and is restricted from rotating around the container axis with respect to the sleeve, and a rotation restricting shaft that is located inside the rotation restricting shaft in the radial direction. Rotation restriction The rotation around the container axis with respect to the shaft is restricted, and the engaging cylinder portion fixed to the middle plate portion and the first spiral groove located on the radial inside of the engaging cylinder portion on the outer peripheral surface. The spiral cylinder portion in which the above is formed and the columnar portion located inside the spiral cylinder portion in the radial direction, the rotation around the container axis with respect to the operation cylinder portion is restricted, and the second spiral groove is formed on the outer peripheral surface. By engaging with the first spiral groove on the inner peripheral surface of the engaging cylinder portion when the spiral cylinder portion and the engaging cylinder portion rotate relative to each other around the container axis. A first engaging portion that moves the engaging cylinder portion up and down is formed, and when the columnar portion and the spiral cylinder portion rotate relative to each other on the inner peripheral surface of the spiral cylinder portion, A second engaging portion is formed that moves the spiral cylinder portion up and down with respect to the columnar portion by engaging with the second spiral groove.

According to the above aspect, when the sleeve and the operation cylinder portion are relatively rotated around the container axis, the first spiral groove and the first engaging portion are engaged (first operation), or the second spiral groove is formed. By engaging the second engaging portion with the second engaging portion (second operation), the middle dish portion is raised. As a result, the contents are fed upward, so that the user can use the contents.
Further, the engaging cylinder portion is located inside the rotation restricting shaft in the radial direction, the spiral cylinder portion is located inside the engaging cylinder portion in the radial direction, and the columnar portion is located inside the spiral cylinder portion in the radial direction. .. As a result, in the initial state, the rotation restricting shaft, the engaging cylinder portion, the spiral cylinder portion, and the columnar portion can be arranged at the same position in the vertical direction, and the total length of the entire feeding container in the vertical direction is reduced. be able to. Then, since the middle dish portion is raised by both the first operation and the second operation described above, the stroke amount of the middle dish portion can be increased.
Further, the relative rotation of the inner plate portion, the engaging cylinder portion, the rotation restricting shaft, and the sleeve around the container shaft is regulated. As a result, when the operating cylinder portion is rotated with respect to the sleeve in the feeding direction, the inner plate portion rises without rotating with respect to the sleeve. Therefore, for example, even when the tip of the content is tilted with respect to the container axis, the content rises without changing the tilting direction of the tip of the content, and the operability can be improved.

Here, a sliding piece that slides with respect to the outer peripheral surface of the sleeve when the operation cylinder portion rotates about the container axis with respect to the sleeve is arranged between the operation cylinder portion and the sleeve. It may have been.

In this case, rattling when the operation cylinder portion and the sleeve rotate relative to each other can be suppressed by the sliding piece.

Further, the upper end portion of the second spiral groove may be formed with a regulating protrusion that regulates the upward detachment of the second engaging portion from the second spiral groove.

In this case, when the spiral cylinder portion rises by a predetermined amount while rotating with respect to the columnar portion, the second engaging portion comes into contact with the regulation protrusion. Therefore, further rotation of the spiral cylinder portion is restricted. Thereby, for example, even when the second spiral groove is opened upward, it is possible to prevent the second engaging portion from being separated from the second spiral groove upward.

According to the above aspect of the present invention, it is possible to provide a feeding container capable of increasing the stroke amount of the inner plate portion while reducing the total length in the vertical direction.

As shown in FIG. 1, the lower end portion of the eclipsed tubular cap 60 is externally fitted to the upper tubular portion 12. When the cap 60 is attached to the upper cylinder portion 12, the holding protrusion 12a comes into contact with the inner peripheral surface of the cap 60.

As shown in FIGS. 2B and 2C, the inner member 10b has a lower plate portion 13, a fitting cylinder portion 14, a columnar portion 15, and a plurality of sliding pieces 16. The lower plate portion 13 is formed in a disk shape in a plan view. The fitting cylinder portion 14 extends upward from the outer peripheral edge of the lower plate portion 13. An annular protrusion 14a is formed at the lower end of the fitting cylinder portion 14 so as to project outward in the radial direction. The annular protrusion 14a is formed on the outer peripheral surface of the fitting cylinder portion 14 over the entire circumference. A plurality of fitting ribs 14b are formed on the outer peripheral surface of the fitting cylinder portion 14 located above the annular protrusion 14a. The plurality of fitting ribs 14b extend in the vertical direction and are arranged at intervals in the circumferential direction.

By fitting the fitting rib 14b into the fitting groove 11b, the rotation of the inner member 10b with respect to the outer member 10a around the container shaft O is restricted. Further, by inserting the annular protrusion 14a into the annular groove portion 11a, the vertical movement of the inner member 10b with respect to the outer member 10a is restricted. With these configurations, the inner member 10b is fixed to the outer member 10a (see FIG. 1). The configuration for fixing the inner member 10b to the outer member 10a may be appropriately changed.

As shown in FIGS. 2B and 2C, the columnar portion 15 extends upward from the radial center portion of the lower plate portion 13. A second spiral groove 15a is formed on the outer peripheral surface of the columnar portion 15. The second spiral groove 15a of the present embodiment is a double-threaded screw (multi-threaded screw), but the second spiral groove 15a may be a single-threaded screw. The second spiral groove 15a is open upward.

The plurality of sliding pieces 16 extend upward from the fitting cylinder portion 14. The sliding pieces are arranged at intervals in the circumferential direction. A slit 17 is provided between the sliding pieces 16. The sliding piece 16 has a shape in which the tubular portion is divided by the slit 17. The sliding piece 16 can be elastically deformed in the radial direction starting from the lower end portion (upper end of the fitting cylinder portion 14).

The sliding piece 16 has a lower portion 16b having an outer diameter and an inner diameter equivalent to those of the fitting cylinder portion 14, and an upper portion 16a located above the lower portion 16b. The inner diameter of the upper portion 16a is equivalent to the inner diameter of the lower portion 16b, but the outer diameter of the upper portion 16a is smaller than the outer diameter of the lower portion 16b. A protrusion 16c is formed on the inner peripheral surface of the upper portion 16a so as to project inward in the radial direction. The protrusion 16c is in contact with the outer peripheral surface of the lower sleeve portion 52 of the sleeve 50 (see FIG. 1).

The fitting protrusion 54 of the sleeve 50 is located in the recess 16d. The outer peripheral surface of the lower portion 16b is in contact with the inner peripheral surface of the operation cylinder portion 11.
Each sliding piece 16 is sandwiched between the lower sleeve portion 52 and the operation cylinder portion 11. The sliding piece 16 suppresses rattling when the sleeve 50 and the operating portion 10 rotate relative to each other.

Further, for example, when the sleeve 50 and the operating portion 10 are made of a material having a large coefficient of friction with each other, if the sleeve 50 and the operating portion 10 are slid without providing the sliding piece 16, resistance due to friction is generated. Is transmitted to the user, which leads to a decrease in operability. On the other hand, by providing the sliding piece 16 capable of reducing the frictional force, the operating portion 10 can be smoothly rotated with respect to the sleeve 50. In the present embodiment, since the rotation of the sliding piece 16 with respect to the operating portion 10 is restricted, the sliding piece 16 may be formed of a material having a small coefficient of friction with the sleeve 50.

The lower end of the first spiral groove 21 is open downward, but the upper end is not open upward. That is, the upper end of the first spiral groove 21 is located below the upper end of the spiral cylinder portion 20.

A second engaging portion 22 projecting inward in the radial direction is formed on the inner peripheral surface of the spiral tubular portion 20. The second engaging portion 22 extends at an angle with respect to the container shaft O so as to match the shape of the second spiral groove 15a. In the present embodiment, since the second spiral groove 15a is a double-threaded screw, the spiral tubular portion 20 has two second engaging portions 22 in accordance with this. The two second engaging portions 22 are arranged at intervals in the circumferential direction.

The spiral cylinder portion 20 is formed with two slits 23 extending in the vertical direction. The slit 23 is formed from the lower end of the spiral cylinder portion 20 to the central portion in the vertical direction of the spiral cylinder portion 20. The slit 23 and the second engaging portion 22 are arranged at different positions in the circumferential direction.
When the spiral cylinder portion 20 rotates relative to the columnar portion 15 around the container shaft O, the second engaging portion 22 and the second spiral groove 15a engage with each other, so that the spiral cylinder portion 20 moves up and down. To do.

As shown in FIGS. 4A, 4B, and 4C, the inner plate member 30 has an inner plate portion 31 and an engaging cylinder portion 32. The inner plate portion 31 and the engaging cylinder portion 32 of the present embodiment are integrally formed, whereby the engaging cylinder portion 32 is fixed to the inner plate portion 31. The inner plate portion 31 and the engaging cylinder portion 32 may be formed separately and fixed to each other.

A plurality of holding ribs 31a extending in the vertical direction are formed on the inner peripheral surface of the inner dish portion 31 at intervals in the circumferential direction. The holding rib 31a ensures that the contents are more securely fixed in the inner pan 31. The engaging cylinder portion 32 extends downward from the lower surface of the inner plate portion 31. The outer diameter of the engaging cylinder portion 32 is smaller than the outer diameter of the inner plate portion 31.

The engaging cylinder portion 32 is mounted on the outside of the spiral cylinder portion 20 (see FIG. 1). As shown in FIG. 4B, two (plurality) regulating ribs 33 projecting outward in the radial direction are formed on the outer peripheral surface of the engaging cylinder portion 32. The two regulating ribs 33 are arranged at intervals in the circumferential direction, and extend in the vertical direction over the entire length of the engaging cylinder portion 32.

Two (plurality) notches 34 are formed in the engaging cylinder portion 32. The two cut portions 34 penetrate the engaging cylinder portion 32 in the radial direction and are arranged at intervals in the circumferential direction. The two cut portions 34 extend in the vertical direction from the lower end of the engaging cylinder portion 32 to the central portion in the vertical direction of the engaging cylinder portion 32.

Four first regulating portions 35 are formed on the outer peripheral surface of the engaging cylinder portion 32. The four first regulating portions 35 project from the outer peripheral surface of the engaging cylinder portion 32 toward the outer side in the radial direction at the lower end portion of the engaging cylinder portion 32, and are arranged at intervals in the circumferential direction. The first regulation unit 35 extends along the circumferential direction. The upper surface of the first regulation unit 35 is located in a plane substantially orthogonal to the container axis O. The lower surface of the first regulating portion 35 is inclined downward as it goes inward in the radial direction. The positions of the first regulating portion 35 in the circumferential direction are different from the positions of the regulating rib 33 and the notch 34 in the circumferential direction. The number of the regulation rib 33, the notch 34, and the first regulation 35 can be changed as appropriate.

A first engaging portion 36 projecting inward in the radial direction is formed on the inner peripheral surface of the lower end portion of the engaging cylinder portion 32. The first engaging portion 36 is inclined and extends with respect to the container shaft O so as to match the shape of the first spiral groove 21. In the present embodiment, since the first spiral groove 21 is a double-threaded screw, the engaging cylinder portion 32 has two first engaging portions 36 in accordance with this. The two first engaging portions 36 are arranged at intervals in the circumferential direction.

When the engaging cylinder portion 32 and the spiral cylinder portion 20 rotate relative to each other around the container shaft O, the first engaging portion 36 and the first spiral groove 21 engage with each other, so that the engaging cylinder portion 32 spirals. Ascends or descends with respect to the cylinder portion 20. At this time, since the middle dish portion 31 is fixed to the engaging cylinder portion 32, the middle dish portion 31 also rises or falls.

As shown in FIGS. 5A and 5B, the rotation restricting shaft 40 is formed in a tubular shape extending in the vertical direction. On the inner peripheral surface of the rotation restricting shaft 40, two first restricting grooves 41 that are recessed outward in the radial direction and two second restricting portions 42 that project inward in the radial direction are formed. The two first regulation grooves 41 extend in the vertical direction and are formed over the entire length of the rotation regulation shaft 40. The two first regulation grooves 41 are arranged at intervals in the circumferential direction.

The two second restricting portions 42 are arranged at the upper end portion of the rotation restricting shaft 40 and extend along the circumferential direction. The lower surface of the second regulating portion 42 is located in a plane substantially orthogonal to the container axis O. The upper surface of the second regulating portion 42 is inclined downward as it goes inward in the radial direction.

Two second regulation grooves 43 that are recessed inward in the radial direction are formed on the outer peripheral surface of the rotation regulation shaft 40. The two second regulation grooves 43 extend in the vertical direction and are arranged at intervals in the circumferential direction. The upper end of the second regulation groove 43 is open upward, but the lower end is not open downward. That is, the lower end of the second regulation groove 43 is located above the lower end of the rotation regulation shaft 40. The first regulation groove 41 and the second regulation groove 43 are formed at different positions in the circumferential direction. The number of the first regulation groove 41, the second regulation section 42, and the second regulation groove 43 can be changed as appropriate.

The rotation restricting shaft 40 is mounted on the outside of the engaging cylinder portion 32 (see FIG. 1). By entering the regulating rib 33 into the first regulating groove 41, the rotation of the engaging cylinder portion 32 around the container shaft O with respect to the rotation regulating shaft 40 is restricted. When the engaging cylinder portion 32 moves up and down with respect to the rotation regulation shaft 40, the regulation rib 33 and the first regulation groove 41 slide up and down. Further, the first regulation unit 35 and the second regulation unit 42 face each other in the vertical direction. When the engaging cylinder portion 32 rises by a predetermined amount with respect to the rotation restricting shaft 40, the first regulating portion 35 comes into contact with the second regulating portion 42 from below. As a result, the rise of the middle plate member 30 exceeding a predetermined amount is restricted.

As shown in FIG. 1, the sleeve 50 is formed in a cylindrical shape coaxial with the container shaft O as a whole. The sleeve 50 has an upper sleeve portion 51 and a lower sleeve portion 52. The upper sleeve portion 51 surrounds the inner plate portion 31 from the outside in the radial direction. The upper end surface of the upper sleeve portion 51 is inclined with respect to the container shaft O. The inner peripheral surface of the upper sleeve portion 51 is formed smoothly over the entire area. As a result, it is possible to prevent the contents from being scraped when the inner plate portion 31 and the contents move up and down with respect to the sleeve 50.

The lower sleeve portion 52 is located below the upper sleeve portion 51. The inner diameter and outer diameter of the lower sleeve portion 52 are smaller than the inner diameter and outer diameter of the upper sleeve portion 51. The lower sleeve portion 52 surrounds the rotation restricting shaft 40 from the outside in the radial direction. The lower sleeve portion 52 is formed with a regulation protrusion 53 and a fitting protrusion 54. The fitting protrusion 54 projects radially outward from the outer peripheral surface of the lower sleeve portion 52, and is formed in an annular shape in a plan view. The fitting protrusion 54 is fitted in the recess 16d of the operating portion 10.

The regulation protrusion 53 protrudes inward in the radial direction from the inner peripheral surface of the lower sleeve portion 52. The regulation protrusion 53 extends in the vertical direction. Two regulation protrusions 53 are formed at intervals in the circumferential direction.

By entering the regulation protrusion 53 into the second regulation groove 43 of the rotation regulation shaft 40, the rotation of the rotation regulation shaft 40 around the container shaft O with respect to the sleeve 50 is restricted. When the rotation regulation shaft 40 moves up and down with respect to the sleeve 50, the regulation protrusion 53 and the second regulation groove 43 slide up and down. Since the lower end of the second regulation groove 43 does not open downward, when the rotation regulation shaft 40 rises by a predetermined amount with respect to the sleeve 50, the inner surface of the lower end of the second regulation groove 43 hits the regulation protrusion 53 from below. Get in touch. As a result, the rise of the rotation restricting shaft 40 exceeding a predetermined amount is restricted.

The sleeve 50 of the present embodiment is made of metal, and the thickness is substantially constant as a whole. However, the sleeve 50 may be made of resin. Even when the sleeve 50 is made of resin, the surface can be decorated to improve the appearance. Further, in particular, by performing vapor deposition on the resin sleeve 50, metallic luster can be imparted and a high-class feeling can be given.

Next, the operation of the feeding container 1A configured as described above will be described.

When using the feeding container 1A, first, the cap 60 is removed from the operation unit 10. Next, for example, by grasping the sleeve 50 and the operating portion 10 with both hands, the operating portion 10 is rotated about the container shaft O with respect to the sleeve 50. At this time, since the relative rotation between the outer member 10a and the inner member 10b is regulated by the fitting rib 14b and the fitting groove 11b, the outer member 10a and the inner member 10b rotate integrally. Further, the relative rotation between the sleeve 50 and the rotation restricting shaft 40 is regulated by the regulation protrusion 53 and the second regulation groove 43, and the relative rotation between the rotation regulation shaft 40 and the middle plate member 30 is regulated by the regulation rib 33 and the first regulation rib 33. It is regulated by the regulation groove 41.

According to the above configuration, when the operation portion 10 and the sleeve 50 are relatively rotated, the columnar portion 15 and the spiral tubular portion 20 are integrally rotated with respect to the engaging tubular portion 32, or the columnar portion 15 is formed. At least one of the actions of rotating or rotating with respect to the spiral tube portion 20 occurs.

When the columnar portion 15 and the spiral tubular portion 20 are integrally rotated relative to the engaging tubular portion 32 in the feeding direction, the first spiral groove 21 and the first engaging portion 36 are engaged with each other. , The engaging cylinder portion 32 (middle plate member 30) rises with respect to the spiral cylinder portion 20. In this specification, the operation of raising the middle plate member 30 by the relative rotation of the spiral cylinder portion 20 and the engaging cylinder portion 32 in the feeding direction is referred to as "first operation".

When the columnar portion 15 and the spiral tubular portion 20 rotate relative to each other in the feeding direction, the second spiral groove 15a and the second engaging portion 22 engage with each other, so that the spiral tubular portion 20 has a relative rotation with respect to the columnar portion 15. And rise. At this time, the inner surface of the first spiral groove 21 pushes up the first engaging portion 36 upward, so that the middle plate member 30 also rises. The operation in which the middle plate member 30 is raised by the relative rotation of the columnar portion 15 and the spiral cylinder portion 20 in the feeding direction is referred to as a "second operation" in the present specification.

That is, when the sleeve 50 and the operation unit 10 are relatively rotated in the feeding direction, the middle plate member 30 is raised by at least one of the first operation and the second operation, whereby the contents are fed upward from the sleeve 50 ( (See FIG. 6). Which of the first operation and the second operation occurs may vary depending on the frictional resistance between the members and the like, but in any case, since the contents are fed out, the user can use the contents. In some cases, both the first operation and the second operation occur at the same time.

Further, when the middle plate member 30 rises by a predetermined amount with respect to the sleeve 50, the first regulation portion 35 and the second regulation portion 42 come into contact with each other, and the regulation protrusion 53 comes into contact with the inner surface of the lower end of the second regulation groove 43. .. Therefore, the rise of the middle plate member 30 exceeding a predetermined amount is restricted. As described above, the feeding container 1A is configured so that the maximum rising position of the middle plate member 30 with respect to the sleeve 50 does not change regardless of which of the first operation and the second operation occurs first.

Further, in the present embodiment, the frictional force when the columnar portion 15 and the spiral cylinder portion 20 rotate relative to each other becomes larger than the frictional force when the spiral cylinder portion 20 and the engaging cylinder portion 32 rotate relative to each other. There is. As a result, the first operation is preferentially generated over the second operation. Therefore, for example, it is possible to prevent the second engaging portion 22 from being disengaged upward from the upper end opening of the second spiral groove 15a due to the second operation occurring first.

Regarding the magnitude relationship of the frictional force described above, for example, the depth of the groove is different between the first spiral groove 21 and the second spiral groove 15a, and the amount of protrusion is different between the first engaging portion 36 and the second engaging portion 22. It can be realized by making it different. That is, the shallower the spiral groove or the larger the amount of protrusion of the engaging portion, the larger the frictional force when the spiral groove and the engaging portion slide. Therefore, the second spiral groove 15a may be formed shallower than the first spiral groove 21, or the protruding amount of the second engaging portion 22 may be larger than the protruding amount of the first engaging portion 36. Further, the depth of the second spiral groove 15a may be increased downward, and only the initial frictional force in the second operation may be increased so that the first operation occurs before the second operation.

When the second operation occurs after the first operation, the first regulation unit 35 and the second regulation unit 42 are before the second engagement portion 22 reaches the upper end of the second spiral groove 15a. The ascent of the middle plate member 30 is restricted by the contact with and the regulation protrusion 53 reaching the lower end of the second regulation groove 43. In the state where the ascending of the middle plate member 30 is restricted, the relative rotation of the operation unit 10 and the sleeve 50 in the feeding direction is also restricted. Therefore, when the second operation occurs after the first operation, the second engaging portion 22 does not separate from the second spiral groove 15a.

Although detailed description will be omitted, when the sleeve 50 and the operating portion 10 are relatively rotated in the accommodating direction, the engagement between the second spiral groove 15a and the second engaging portion 22 and the first spiral groove 21 and the first By engaging with the engaging portion 36, the middle plate member 30 can be lowered to the position in the initial state (FIG. 1). As a result, the contents can be accommodated in the sleeve 50 again.

As described above, the feeding container 1A of the present embodiment extends upward from the middle plate portion 31, the operation cylinder portion 11, and the operation cylinder portion 11 for holding the contents, and extends the middle plate portion 31 in the radial direction. The sleeve 50 surrounding from the outside, the rotation restricting shaft 40 in which the rotation of the container shaft O with respect to the sleeve 50 is restricted, and the rotation of the container shaft O with respect to the rotation restricting shaft 40 are regulated, and the inner plate portion 31 The fixed engaging cylinder portion 32, the spiral cylinder portion 20 having the first spiral groove 21 formed on the outer peripheral surface, and the rotation around the container shaft O with respect to the operation cylinder portion 11 are restricted, and the second spiral groove 21 is formed on the outer peripheral surface. A columnar portion 15 in which a spiral groove 15a is formed is provided.

Then, when the spiral cylinder portion 20 and the engaging cylinder portion 32 rotate relative to each other around the container shaft O, the spiral cylinder portion 20 and the engaging cylinder portion 32 engage with the first spiral groove 21 on the inner peripheral surface of the engaging cylinder portion 32. A first engaging portion 36 that moves the combined cylinder portion 32 up and down is formed, and when the columnar portion 15 and the spiral cylinder portion 20 rotate relative to each other around the container axis O on the inner peripheral surface of the spiral cylinder portion 20. A second engaging portion 22 that moves the spiral tubular portion 20 up and down with respect to the columnar portion 15 by engaging with the second spiral groove 15a is formed.

According to such a configuration, when the sleeve 50 and the operation cylinder portion 11 are relatively rotated around the container shaft O, the first spiral groove 21 and the first engaging portion 36 are engaged (first operation). Alternatively, the middle plate portion 31 is raised by engaging the second spiral groove 15a with the second engaging portion 22 (second operation). As a result, the contents are fed upward, so that the user can use the contents.

Further, the engaging cylinder portion 32 is located inside the rotation restricting shaft 40 in the radial direction, the spiral cylinder portion 20 is located inside the engaging cylinder portion 32 in the radial direction, and the columnar portion 15 is located in the radial direction of the spiral cylinder portion 20. It is located inside. As a result, in the initial state (FIG. 1), the rotation restricting shaft 40, the engaging cylinder portion 32, the spiral cylinder portion 20, and the columnar portion 15 can be arranged at the same positions in the vertical direction, and the feeding container 1A can be arranged. The total length in the vertical direction of the whole can be reduced. Then, since the middle dish portion 31 is raised by both the first operation and the second operation described above, the stroke amount of the middle dish portion 31 can be increased.

Further, the relative rotation of the inner plate portion 31, the engaging cylinder portion 32, the rotation restricting shaft 40, and the sleeve 50 around the container shaft O is restricted. As a result, when the operation cylinder portion 11 is rotated with respect to the sleeve 50 in the feeding direction, the inner plate portion 31 rises with respect to the sleeve 50 without rotating. Therefore, for example, even when the tip of the content is tilted with respect to the container shaft O, the content rises without changing the tilting direction of the tip of the content, and the operability can be improved.

Further, between the operation cylinder portion 11 and the sleeve 50, a sliding piece 16 that slides with respect to the outer peripheral surface of the sleeve 50 when the operation cylinder portion 11 rotates about the container shaft O with respect to the sleeve 50 is provided. It is formed. The sliding piece 16 can suppress rattling when the operation cylinder portion 11 and the sleeve 50 rotate relative to each other. Further, since the sliding piece 16 is formed on the inner member 10b, it is possible to suppress an increase in the number of parts and reduce the cost.

Further, the sliding piece 16 is formed with a protrusion 16c that protrudes inward in the radial direction and is in contact with the outer peripheral surface of the sleeve 50. As a result, the contact area between the sliding piece 16 and the sleeve 50 is reduced, and the sliding piece 16 and the sleeve 50 can be slid more smoothly.

(Second Embodiment)
Next, the second embodiment according to the present invention will be described, but the basic configuration is the same as that of the first embodiment. Therefore, the same reference numerals are given to the same configurations, the description thereof will be omitted, and only the different points will be described.
In the present embodiment, the shapes of the inner member 10b and the spiral cylinder portion 20 are different from those of the first embodiment.

As shown in FIG. 7, in the feeding container 1B of the present embodiment, the regulation protrusion 15b and the lightening portion 15c are formed on the columnar portion 15. The regulating protrusions 15b are formed inside the upper ends of the two second spiral grooves 15a, respectively. As shown in FIG. 8A, the width of the regulation protrusion 15b in the circumferential direction becomes smaller toward the outer side in the radial direction. In other words, the side surface (the surface facing the circumferential direction) of the regulation protrusion 15b is inclined when viewed from the vertical direction. The radial outer end of the regulation protrusion 15b is located radially inside the outer peripheral surface of the columnar portion 15. As shown in FIG. 8B, the regulation protrusion 15b extends in the vertical direction.

As shown in FIG. 7, the lightening portion 15c is recessed downward from the upper end surface of the columnar portion 15. The inner diameter of the lightening portion 15c becomes smaller toward the bottom. The lightening portion 15c is formed in a trapezoidal shape in a vertical cross-sectional view.
Further, the slit 23 is not formed in the spiral cylinder portion 20 of the present embodiment.

In the case of the present embodiment, when the spiral cylinder portion 20 rises by a predetermined amount while rotating with respect to the columnar portion 15 in the feeding direction, the second engaging portion 22 comes into contact with the regulation protrusion 15b. Therefore, the further rotation of the spiral cylinder portion 20 in the feeding direction is restricted, and the second engaging portion 22 is suppressed from being separated from the second spiral groove 15a upward. Therefore, the second operation may occur before the first operation, and it is not necessary to set the magnitude relationship of friction as in the first embodiment.

Further, the slit 23 is not formed in the spiral cylinder portion 20 of the present embodiment. As a result, the spiral cylinder portion 20 is less likely to be deformed, and the phenomenon that the second engaging portion 22 gets over the regulation protrusion 15b due to the deformation can be suppressed.

When the inner member 10b is formed by injection molding, a mold (core) having a spiral protrusion having the same shape as the second spiral groove 15a is rotated at the time of die cutting. When the spiral protrusion of the mold gets over the regulation protrusion 15b, the upper end of the columnar portion 15 is easily deformed due to the formation of the lightening portion 15c, which facilitates the die cutting.

Further, the feeding container 1B of the second embodiment can stabilize the operation as compared with the feeding container 1A of the first embodiment in that the magnitude relation of the frictional force is not used. On the other hand, since the feeding container 1A does not form the regulation protrusion 15b inside the second spiral groove 15a as compared with the feeding container 1B, the inner member 10b can be easily molded by injection molding.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, a configuration different from that of the first embodiment and the second embodiment may be adopted as a configuration in which the second engaging portion 22 does not disengage from the second spiral groove 15a. Specifically, a configuration may be adopted in which the upper end of the second spiral groove 15a is not open. Further, even when the upper end of the second spiral groove 15a is open, the configuration may be such that the first operation is completed before the second operation is completed.

Further, it is possible to appropriately replace the constituent elements in the above-described embodiment with well-known constituent elements without departing from the gist of the present invention, and the above-described embodiments and modifications may be appropriately combined.
