The middle plate portion 31 is formed in a cylindrical shape with a bottom, and the lower end portion of the contents is accommodated therein. As the content, stick-shaped solid cosmetics (eg, lipstick, lip balm), stick-shaped solid glue, or the like can be used. Note that the type of content can be changed as appropriate.

(direction definition)
In the present embodiment, the central axes of the operating portion 10, the rotation restricting shaft 20, the middle plate member 30, the second spiral cylinder portion 40, the sleeve 50, the cap 60, and the intervening member 70 are positioned on a common axis. placed in a state. Hereinafter, this common axis will be referred to as container axis O, and the direction along container axis O will be referred to as the vertical direction (container axial direction). In a plan view viewed from above and below, the direction intersecting the container axis O is called the radial direction, and the direction rotating around the container axis O is called the circumferential direction. The opening side of the inner plate portion 31 in the vertical direction is referred to as the upper side, and the operation section 10 side is referred to as the lower side. A section along the container axis O is called a vertical section, and a section orthogonal to the container axis O is called a transverse section.

In addition, the dispensing container 1 rotates the sleeve 50 and the operating portion 10 relative to each other around the container axis O to raise the contents and extend the contents upward from the sleeve 50 or to lower the contents to the sleeve. 50 can be accommodated again. In this embodiment, among the rotation directions about the container axis O, the direction in which the contents are raised is called the delivery direction, and the direction in which the contents are lowered is called the storage direction.

The operating portion 10 is configured by combining an outer member 10a and an inner member 10b. Although the outer member 10a and the inner member 10b of this embodiment are formed separately, they may be integrally formed. The inner member 10b is located radially inside the outer member 10a.

As shown in FIG. 2A , the outer member 10 a has an operating tube portion 11 extending in the vertical direction and an upper tube portion 12 extending upward from the operating tube portion 11 . An annular groove portion 11a that is recessed radially outward is formed in the lower end portion of the operation cylinder portion 11 . The annular groove portion 11a is formed on the inner peripheral surface of the operation cylinder portion 11 over the entire circumference. A plurality of fitting grooves 11b are formed in a portion of the inner peripheral surface of the operation cylinder portion 11 located above the annular groove portion 11a. The plurality of fitting grooves 11b extend in the vertical direction and are arranged at intervals in the circumferential direction.

The outer diameter of the upper cylinder portion 12 is smaller than the outer diameter of the operation cylinder portion 11 . A plurality of holding protrusions 12a are formed on the outer peripheral surface of the upper cylindrical portion 12 . The holding protrusions 12a are arranged at intervals in the circumferential direction. As shown in FIG. 1 , the lower end portion of a cap 60 having a capped tubular shape is fitted onto the upper tubular portion 12 . When the cap 60 is attached to the upper tubular portion 12 , the holding protrusion 12 a contacts 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 tubular portion 14, and a columnar portion 15. As shown in FIGS. The lower plate portion 13 is formed in a disc shape in 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 14 and protrudes radially outward. The annular protrusion 14a is formed on the outer peripheral surface of the fitting tube portion 14 over the entire circumference. A plurality of fitting ribs 14b are formed on a portion of the outer peripheral surface of the fitting tube portion 14 located above the annular projection 14a. The plurality of fitting ribs 14b extend in the vertical direction and are spaced apart in the circumferential direction.

By fitting the fitting rib 14b into the fitting groove 11b, rotation of the inner member 10b about the container axis O with respect to the outer member 10a is restricted. Moreover, the vertical movement of the inner member 10b with respect to the outer member 10a is restricted by the annular protrusion 14a entering the annular groove 11a. 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 changed as appropriate.

As shown in FIGS. 2B and 2C, the columnar portion 15 extends upward from the radial center portion of the lower plate portion 13 . Two (a plurality of) first guide ribs 15 a are formed on the outer peripheral surface of the columnar portion 15 so as to protrude radially outward. The two first guide ribs 15 a are circumferentially spaced apart and extend upward from the lower end of the columnar portion 15 . The upper ends of the first guide ribs 15 a are positioned below the upper ends of the columnar portions 15 . Two (plural) third restricting portions 15b are formed in a portion of the outer peripheral surface of the columnar portion 15 located above the first guide ribs 15a. The two third restricting portions 15b protrude radially outward from the outer peripheral surface of the columnar portion 15 and are spaced apart in the circumferential direction. The numbers of the first guide ribs 15a and the third restricting portions 15b can be changed as appropriate, and may be one or three or more.

The circumferential position of the third restricting portion 15b is different from the circumferential position of the first guide rib 15a. That is, the third restricting portion 15b is arranged at a position not overlapping with the first guide rib 15a in plan view. A groove portion 15c that is recessed downward is formed in the upper end surface of the columnar portion 15 . In plan view, the groove portion 15c extends in the radial direction and is arranged at the same position as the first guide rib 15a in the circumferential direction.

As shown in FIGS. 3A, 3B, and 3C, the rotation restricting shaft 20 has a tubular shape extending in the vertical direction. Two (plural) first guide grooves 21 are formed on the inner peripheral surface of the rotation restricting shaft 20 so as to be recessed radially outward. The two first guide grooves 21 extend over the entire length of the rotation restricting shaft 20 in the vertical direction and are spaced apart in the circumferential direction.

Two (plurality) of second guide grooves 22 recessed radially inward are formed on the outer peripheral surface of the rotation restricting shaft 20 . The two second guide grooves 22 extend over the entire length of the rotation restricting shaft 20 in the vertical direction and are spaced apart in the circumferential direction. The first guide groove 21 and the second guide groove 22 are arranged at different positions in the circumferential direction.
Two (plurality) of fourth restricting portions 23 projecting radially inward are formed on the inner peripheral surface of the rotation restricting shaft 20 . The two fourth restricting portions 23 are arranged at different positions from the first guide groove 21 in the circumferential direction.

Four (a plurality of) second restricting portions 24 projecting radially outward are formed on the outer peripheral surface of the rotation restricting shaft 20 . The four second restricting portions 24 are arranged at the upper end portion of the rotation restricting shaft 20 . The second restricting portion 24 and the second guide groove 22 are arranged at different positions in the circumferential direction. The numbers of the first guide grooves 21, the second guide grooves 22, the fourth restricting portions 23, and the second restricting portions 24 can be changed as appropriate.

The rotation restricting shaft 20 is attached to the outside of the columnar portion 15 (see FIG. 1). Since the first guide rib 15 a enters the first guide groove 21 , rotation of the rotation restricting shaft 20 about the container axis O with respect to the columnar portion 15 is restricted. Further, when the rotation restricting shaft 20 moves up and down with respect to the columnar portion 15, the first guide rib 15a and the first guide groove 21 slide up and down. When the rotation restricting shaft 20 rises by a predetermined amount with respect to the columnar portion 15, the fourth restricting portion 23 contacts the third restricting portion 15b, thereby restricting the rotation restricting shaft 20 from further rising.

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

A plurality of vertically extending holding ribs 31a are formed on the inner peripheral surface of the intermediate plate portion 31 at intervals in the circumferential direction. The holding ribs 31a more reliably fix the contents in the middle plate portion 31. As shown in FIG. The first helical cylinder portion 32 extends downward from the lower surface of the intermediate plate portion 31 . The outer diameter of the first helical cylinder portion 32 is smaller than the outer diameter of the intermediate plate portion 31 .

A first spiral groove 32 a is formed on the outer peripheral surface of the first spiral cylinder portion 32 . Although the first helical groove 32a of this embodiment is a double thread (multiple thread), the first helical groove 32a may be a single thread. As shown in FIG. 4C, the lower end of the first spiral groove 32a is located above the lower end of the first spiral cylinder portion 32 and does not open downward. As shown in FIG. 4B , two (plurality) of second guide ribs 33 protruding radially inward are formed on the inner peripheral surface of the first helical cylinder portion 32 . The two second guide ribs 33 are circumferentially spaced apart and extend vertically over the entire length of the first helical cylinder portion 32 .

Two (plurality) cut portions 34 are formed in the first helical cylinder portion 32 . The two cut portions 34 penetrate the first helical cylinder portion 32 in the radial direction and are spaced apart in the circumferential direction. The two cut portions 34 extend vertically from the lower end of the first spiral tube portion 32 to the center portion of the first spiral tube portion 32 in the vertical direction.

Four (plural) first restricting portions 35 are formed on the inner peripheral surface of the first helical cylinder portion 32 . The four first restricting portions 35 protrude radially inward from the inner peripheral surface of the first helical cylinder portion 32 and are arranged at intervals in the circumferential direction. The position of the first restricting portion 35 in the circumferential direction is different from the positions of the second guide rib 33 and the cut portion 34 in the circumferential direction. Note that the numbers of the second guide ribs 33, the cut portions 34, and the first restricting portions 35 can be changed as appropriate.

The first helical cylinder portion 32 is attached to the outside of the rotation restricting shaft 20 (see FIG. 1). The rotation of the first helical cylinder portion 32 about the container axis O with respect to the rotation restriction shaft 20 is restricted by the second guide rib 33 entering the second guide groove 22 . Further, when the first helical cylinder portion 32 moves up and down with respect to the rotation restricting shaft 20, the second guide rib 33 and the second guide groove 22 slide up and down.

As shown in FIGS. 5A and 5B, the second helical tubular portion 40 is formed in a tubular shape extending in the vertical direction. A second spiral groove 41 is formed on the outer peripheral surface of the second spiral cylinder portion 40 . Although the second helical groove 41 of this embodiment is a double thread (multiple thread), the second helical groove 41 may be a single thread. The second spiral groove 41 extends to the upper end of the second spiral tube portion 40, and the upper end of the second spiral groove 41 opens upward. The lower end of the second spiral groove 41 is located above the lower end of the second spiral cylinder portion 40 and does not open downward.

A first engaging portion 42 protruding radially inward is formed on the inner peripheral surface of the second helical cylinder portion 40 . The first engaging portion 42 extends obliquely with respect to the container axis O so as to match the shape of the first spiral groove 32a. In this embodiment, the first helical groove 32a is a double thread, so the second helical cylinder portion 40 has two first engagement portions 42 accordingly. Although illustration is omitted, the two first engaging portions 42 are arranged with an interval in the circumferential direction.
The second helical cylinder portion 40 is attached to the outside of the first helical cylinder portion 32 (see FIG. 1). When the first helical cylinder portion 32 and the second helical cylinder portion 40 rotate relatively around the container axis O, the first engaging portion 42 and the first helical groove 32a are engaged with each other, thereby rotating the first helical cylinder. The portion 32 and the second helical cylinder portion 40 move vertically relative to each other.

As shown in FIG. 1, the sleeve 50 is formed in a cylindrical shape coaxial with the container axis O as a whole. The sleeve 50 of this embodiment is made of metal and has a uniform thickness as a whole. However, the material of the sleeve 50 can be changed as appropriate, and may be resin or the like. The sleeve 50 has an upper sleeve portion 51 and a lower sleeve portion 52 . The upper sleeve portion 51 surrounds the intermediate plate portion 31 from the radially outer side. The upper end surface of the upper sleeve portion 51 is inclined with respect to the container axis O. As shown in FIG. The inner peripheral surface of the upper sleeve portion 51 is formed smooth over the entire area. As a result, scraping of the contents can be suppressed when the middle plate portion 31 and the contents move up and down with respect to the sleeve 50 .

The lower sleeve portion 52 is positioned below the upper sleeve portion 51 . The inner and outer diameters of the lower sleeve portion 52 are smaller than the inner and outer diameters of the upper sleeve portion 51 . The lower sleeve portion 52 surrounds the second helical cylinder portion 40 from the radial outside. As shown in FIG. 6A, the lower sleeve portion 52 is formed with a protrusion 54 and a second engaging portion 53 . The protrusion 54 protrudes radially outward from the outer peripheral surface of the lower sleeve portion 52 and has an annular shape in a plan view. The projecting portion 54 is positioned above the fitting tube portion 14 of the operating portion 10 .

The second engaging portion 53 is positioned above the projecting portion 54 . As shown in FIG. 6B , the second engaging portion 53 extends obliquely with respect to the container axis O so as to match the shape of the second spiral groove 41 . In this embodiment, the second helical groove 41 is a double thread, so the sleeve 50 has two second engaging portions 53 accordingly. Although not shown, the two second engaging portions 53 are arranged with a space therebetween in the circumferential direction.
When the sleeve 50 and the second helical tube portion 40 rotate relative to each other around the container axis O, the second engaging portion 53 and the second helical groove 41 are engaged with each other, so that the second helical tube portion 40 becomes the sleeve. Ascending or descending relative to 50.

As shown in FIG. 1, the intervening member 70 is formed in a cylindrical shape coaxial with the container axis O. As shown in FIG. The intervening member 70 is sandwiched between the lower sleeve portion 52 and the operating cylinder portion 11 . The intervening member 70 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 operation portion 10 are made of a material having a high coefficient of friction with each other, if the sleeve 50 and the operation portion 10 are slid without providing the intervening member 70, resistance due to friction will be generated. This is transmitted to the user and leads to a decrease in operational feeling. On the other hand, by providing the intervening member 70 capable of reducing the frictional force, the operating portion 10 can be smoothly rotated with respect to the sleeve 50 . In the present embodiment, the intervening member 70 is restricted from rotating with respect to the operating portion 10 , so the intervening member 70 is preferably made of a material having a small coefficient of friction with the sleeve 50 .

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

When using the dispensing container 1 , first, the cap 60 is removed from the operating portion 10 . Next, the operating portion 10 is rotated about the container axis O with respect to the sleeve 50 by, for example, gripping the sleeve 50 and the operating portion 10 with both hands. At this time, since the relative rotation between the outer member 10a and the inner member 10b is restricted by the fitting rib 14b and the fitting groove 11b, the outer member 10a and the inner member 10b rotate together. Relative rotation between the inner member 10b and the rotation restricting shaft 20 is restricted by the first guide grooves 21 and the first guide ribs 15a. Further, relative rotation between the rotation restricting shaft 20 and the first helical cylinder portion 32 (middle plate member 30 ) is restricted by the second guide ribs 33 and the second restricting portion 24 . Therefore, the outer member 10 a , the inner member 10 b , the rotation restricting shaft 20 , and the first helical tubular portion 32 rotate together with respect to the sleeve 50 .

Here, the second helical cylinder portion 40 is provided between the first helical cylinder portion 32 and the sleeve 50 . Therefore, when the first spiral tube portion 32 and the sleeve 50 rotate relative to each other, at least one of the first spiral tube portion 32 and the sleeve 50 rotates with respect to the second spiral tube portion 40 .

When the first helical cylinder portion 32 and the second helical cylinder portion 40 rotate relative to each other in the delivery direction, the first engaging portion 42 and the first helical groove 32a are engaged with each other, so that the first helical cylinder portion 32 (intermediate plate member 30 ) rises with respect to the second helical cylinder portion 40 . In this specification, the operation in which the middle tray member 30 is lifted by the relative rotation of the first helical cylinder portion 32 and the second helical cylinder portion 40 in the delivery direction is referred to as the "first operation".

When the sleeve 50 and the second helical tube portion 40 rotate relative to each other in the delivery direction, the second engaging portion 53 and the second helical groove 41 are engaged with each other so that the second helical tube portion 40 rotates relative to the sleeve 50 . rise against At this time, the inner surface of the first spiral groove 32a is pushed upward by the first engaging portion 42 of the second spiral cylinder portion 40, so that the inner plate member 30 is also raised. In this specification, the operation in which the sleeve 50 and the second helical cylinder portion 40 rotate relative to each other in the delivery direction to raise the intermediate tray member 30 is referred to as the "second operation".

That is, when the sleeve 50 and the operating portion 10 are relatively rotated in the feeding direction, the middle tray member 30 is lifted by at least one of the first action and the second action, thereby feeding the contents upward from the sleeve 50 ( See Figure 7). Which of the first action and the second action occurs may vary depending on the frictional resistance between each member and the like, but the user can use the content because the content is delivered in any case.

Also, for example, consider a case where the first movement occurs first and the first helical cylinder portion 32 reaches the highest position with respect to the second helical cylinder portion 40 . At this time, the first engaging portion 42 is positioned at the lower end of the first spiral groove 32a, but since the lower end of the first spiral groove 32a is not open downward, the first spiral cylinder portion 32 and the second spiral cylinder portion 32 are further arranged than that. Relative rotation in the delivery direction with the helical cylinder portion 40 is restricted. In other words, when the first engaging portion 42 reaches the lower end of the first spiral groove 32a, the relative rotation of the first spiral tube portion 32 and the second spiral tube portion 40 in the delivery direction is restricted.

In this state, when the sleeve 50 and the operating portion 10 are further rotated relative to each other in the delivery direction, the first helical tube portion 32 and the second helical tube portion 40 are integrally rotated relative to the sleeve 50 in the delivery direction. do. This causes a second motion to raise the inner tray member 30 .

Similarly, when the second action occurs first, when the second engaging portion 53 reaches the lower end of the second spiral groove 41, relative rotation of the sleeve 50 and the second spiral tube portion 40 in the delivery direction is regulated. When the sleeve 50 and the operating portion 10 are further rotated relative to each other in the delivery direction in this state, the second spiral tube portion 40 and the sleeve 50 integrally rotate relative to the first spiral tube portion 32 in the delivery direction. This causes the first motion to raise the inner tray member 30 .

Further, when the inner tray member 30 rises by a predetermined amount, the first restricting portion 35 contacts the second restricting portion 24 , and an upward force is applied to the rotation restricting shaft 20 . As a result, the inner tray member 30 and the rotation restricting shaft 20 are raised together. When the rotation restricting shaft 20 rises by a predetermined amount, the fourth restricting portion 23 comes into contact with the third restricting portion 15b, and any further rise of the rotating restricting shaft 20 is restricted. Thus, the first restricting portion 35, the second restricting portion 24, the third restricting portion 15b, and the fourth restricting portion 23 restrict the intermediate plate member 30 from rising above the operating portion 10 by a predetermined amount or more.

In this manner, the delivery container 1 is configured such that the highest position of the inner tray member 30 with respect to the operating portion 10 does not change regardless of which of the first action and the second action occurs first.
Although detailed description is omitted, when the sleeve 50 and the operating portion 10 are relatively rotated in the accommodation direction, the engagement between the first spiral groove 32a and the first engaging portion 42 and the engagement between the second spiral groove 41 and the second By engaging with the engaging portion 53, the inner tray member 30 can be lowered to the initial state position (FIG. 1). Thereby, the contents can be accommodated in the sleeve 50 again.

As described above, the dispensing container 1 of the present embodiment includes the middle plate portion 31 for holding the contents, the columnar portion 15 extending in the vertical direction, and the operation cylinder in which the rotation of the columnar portion 15 about the container axis O is restricted. An operation portion 10 having a portion 11, a cylindrical rotation restricting shaft 20 radially surrounding the columnar portion 15, and a first spiral groove 32a formed on the outer peripheral surface surrounding the rotation restricting shaft 20 from the radially outer side. A first helical cylinder portion 32 fixed to the middle plate portion 31 and a second helical cylinder portion surrounding the first helical cylinder portion 32 from the outside in the radial direction and having a second helical groove 41 formed on the outer peripheral surface. 40, and a sleeve 50 that extends upward from the operation cylinder portion 11 and surrounds the intermediate plate portion 31 and the second helical cylinder portion 40 from the outside in the radial direction.

Further, the relative rotation of the columnar portion 15, the rotation restricting shaft 20, and the first spiral tube portion 32 around the container axis O is restricted, and the rotation restricting shaft 20 has a A second restricting portion 24 that abuts on a first restricting portion 35 formed on the peripheral surface to restrict the first helical cylinder portion 32 from rising by a predetermined amount or more with respect to the rotation restricting shaft 20, and the outer peripheral surface of the columnar portion 15. and a fourth restricting portion 23 that restricts the rotation restricting shaft 20 from rising by a predetermined amount or more with respect to the columnar portion 15 by coming into contact with the third restricting portion 15b formed at the top. The second helical cylinder portion 40 is engaged with the first helical groove 32a so that when the second helical cylinder portion 40 and the first helical cylinder portion 32 are relatively rotated around the container axis O, the first A first engagement portion 42 is formed to vertically move the helical cylinder portion 32 with respect to the second helical cylinder portion 40 , and the sleeve 50 engages with the second helical groove 41 so that the sleeve 50 and the second helical cylinder are engaged with each other. A second engaging portion 53 is formed to move the second helical cylindrical portion 40 up and down with respect to the sleeve 50 when the cylindrical portion 40 and the cylindrical portion 40 rotate relative to each other around the container axis O.

According to such a configuration, when the sleeve 50 and the operation tube portion 11 are relatively rotated around the container axis O, the columnar portion 15, the rotation restricting shaft 20, and the first spiral tube portion 32 are integrated, It rotates with respect to the sleeve 50 . Then, the first spiral groove 32a and the first engaging portion 42 are engaged (first operation), or the second spiral groove 41 and the second engaging portion 53 are engaged (second operation). ) causes the middle plate portion 31 to rise. As a result, the contents are drawn out upward, so that the user can use the contents.

Further, the rotation restricting shaft 20 surrounds the columnar portion 15 from the outside in the radial direction, the first spiral tube portion 32 surrounds the rotation restricting shaft 20 from the outside in the radial direction, and the second spiral tube portion 40 surrounds the first spiral tube portion 32 in the radial direction. is surrounded from the outside in the radial direction. As a result, in the initial state (FIG. 1), the columnar portion 15, the rotation restricting shaft 20, the first helical cylinder portion 32, and the second helical cylinder portion 40 can be arranged at the same position in the vertical direction. The total length of the feeding container 1 in the vertical direction can be reduced. Then, the middle plate portion 31 can be raised until the second restricting portion 24 contacts the first restricting portion 35 and the fourth restricting portion 23 contacts the third restricting portion 15b. That is, the stroke amount of the middle plate portion 31 is the total value of the stroke amount of the rotation restricting shaft 20 with respect to the columnar portion 15 and the stroke amount of the first helical cylinder portion 32 with respect to the rotation restricting shaft 20 . Thereby, the stroke amount of the intermediate plate portion 31 can be increased.

(Second embodiment)
Next, a second embodiment according to the present invention will be described, but the basic configuration is the same as that of the first embodiment. For this reason, the same reference numerals are assigned to the same configurations, the description thereof is omitted, and only the points of difference will be described.
In this embodiment, the shape and material of the sleeve 50 and the shape of the inner member 10b of the operating portion 10 are different from those of the first embodiment.

As shown in FIG. 8, the sleeve 50 of this embodiment is made of resin. Even when the sleeve 50 is made of resin, the surface can be decorated to improve the appearance. In addition, by vapor-depositing the resin sleeve 50 in particular, it is possible to impart a metallic luster and give a high-class feeling. The role of each part of the sleeve 50 is the same as that described in the first embodiment.
As shown in FIGS. 9A and 9B, the inner member 10b has an intervening tubular portion 16 extending upward from the fitting tubular portion 14. As shown in FIGS. A plurality of slits 17 are formed in the intervening cylinder portion 16 at intervals in the circumferential direction. The slit 17 extends over the entire length of the interposed tubular portion 16 in the vertical direction. The intervening tubular portion 16 is divided into a plurality of elastic pieces by slits 17, and each elastic piece is elastically deformable in the radial direction with its lower end as a starting point. Moreover, each elastic piece is arrange|positioned at intervals in the circumferential direction.

The intervening tubular portion 16 (each elastic piece) has a lower portion 16b whose outer diameter and inner diameter are the same as those of the fitting tubular portion 14, and an upper portion 16a positioned above the lower portion 16b. The inner diameter of upper portion 16a is equal to the inner diameter of lower portion 16b, but the outer diameter of upper portion 16a is smaller than the outer diameter of lower portion 16b. A protrusion 16c protruding radially inward is formed on the inner peripheral surface of the upper portion 16a. The protrusion 16c is formed between the slits 17. As shown in FIG. In other words, the protrusion 16c is formed on each elastic piece. The protrusion 16c is in contact with the outer peripheral surface of the lower sleeve portion 52. As shown in FIG.

A concave portion 16d that is recessed radially inward is formed on the inner peripheral surface of the lower portion 16b. The recess 16 d is formed along the entire circumference of the inner peripheral surface of the intervening tubular portion 16 . In other words, the recess 16d is formed in each elastic piece. A protrusion 54 of the sleeve 50 is positioned in the recess 16d. The outer peripheral surface of the lower portion 16 b is in contact with the inner peripheral surface of the operation cylinder portion 11 .

In this embodiment, the intervening tubular portion 16 plays the role of the intervening member 70 in the first embodiment. That is, the intervening tubular portion 16 (each elastic piece) is sandwiched between the lower sleeve portion 52 and the operating tubular portion 11 and is made of a material having a small coefficient of friction with the sleeve 50 . The intervening cylindrical portion 16 suppresses rattling when the sleeve 50 and the operation portion 10 rotate relatively, and allows the operation portion 10 to rotate smoothly with respect to the sleeve 50 . Since the inner member 10b has the interposed tubular portion 16, the delivery container 1 of the present embodiment does not have the interposed member 70 of the first embodiment.

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

For example, although the delivery container 1 of the above-described embodiment includes the intervening member 70 , the delivery container 1 does not have to include the intervening member 70 .

In addition, it is possible to appropriately replace the components in the above-described embodiments with well-known components without departing from the scope of the present invention, and the above-described embodiments and modifications may be combined as appropriate.
