Description

The present invention relates to a dispensing container.

Conventionally, dispensing containers have been known as containers for storing solid contents that can be spread, such as cosmetics such as lipstick, lip balm, and stick eye shadow, medicines, or stick glue.

For example, Patent Document 1 describes an advancing container that has a case tube with an advancing port at the top end, an advancing member that is positioned radially inside the case tube and supports the contents, and an operating member whose inner circumferential surface is formed with a female thread and that is held rotatably relative to the case tube, with the advancing member having a screwing portion that screws into the female thread of the operating member through a vertically extending slit provided in the case tube.

With this dispenser, the operating member can be rotated relative to the case tube to raise the dispenser member within the case tube, allowing the contents to be dispensed from the dispense opening for use.

JP 2020-25622 A

However, in conventional propelling containers such as those described above, the operating member, case tube, and propelling member are arranged radially in line at least over the height range in which the slits are provided, making it difficult to reduce the size of the container in the radial direction. In addition, when assembling the propelling container, many rotation operations are required to screw the operating member into the propelling member, which is time-consuming.

The present invention aims to solve these problems, and its objective is to provide a dispensing container that is easy to make small in the radial direction and easy to assemble.

The propelling container of the present invention comprises a case tube having an advancing port at an upper end, a screw shaft having an outer circumferential surface formed by a male screw, a propelling member arranged radially inside the case tube so as to be movable up and down while being prevented from rotating, and supporting a content, a screw tube arranged radially outside the screw shaft, and an operating member including an outer tube which is integrated with the outer circumferential surface of the screw tube by fitting, the screw tube having a cylindrical screw tube main body and an elastic piece which extends upward from the screw tube main body and screws into the male screw, the inner circumferential surface of the outer tube having a support surface which supports the elastic piece from the radially outside, and a screw tube having an inner circumferential surface which supports the elastic piece from the radially outside, the screw tube having an inner circumferential surface which supports the elastic piece from the radially outside, and the screw tube having an inner circumferential surface which supports the elastic piece from the radially outside. The case tube has a step surface which reduces in diameter in a stepped manner upward above the mating tube, the case tube has a holding portion which is positioned between the upper surface of the elastic piece and the step surface of the outer tube to hold the operating member so as to be rotatable relative to the operating member, the screw shaft has a vertical band-shaped threaded intermittent portion extending in the vertical direction, the case tube has a guide portion which engages with the threaded intermittent portion to guide the extension member to move in the vertical direction while being prevented from rotating, the holding portion is composed of an enlarged diameter portion having a U-shaped cross-sectional shape around the entire circumference, and the guide portion is connected to the lower end of the enlarged diameter portion .

In the above-described configuration of the dispensing container of the present invention, it is preferable that the guide portion has a sliding resistance portion that slides against the intermittent thread portion to provide resistance to the vertical movement of the dispensing member relative to the case tube.

The present invention provides a dispensing container that is easy to make small in the radial direction and easy to assemble.

FIG.

Below, we will explain an example of a dispensing container 1, which is an embodiment of the present invention, with reference to the drawings.

In this specification, the vertical direction of the dispensing container 1 refers to the direction along the central axis O of the case tube 10, the upper direction refers to the direction in which the contents 2 are dispensed, and the lower direction refers to the opposite direction, the radial direction refers to the direction along a straight line perpendicular to the central axis O, the circumferential direction refers to the direction going around the central axis O, the longitudinal section refers to a section including the central axis O, and the transverse section refers to a section perpendicular to the central axis O.

In addition, in this specification, the up-down direction of the jig 3 refers to the up-down direction when the jig 3 is in an upright position.

The first embodiment of the present invention, a dispensing container 1, shown in FIG. 1, is composed of a case tube 10, a dispensing member 20, an operating member 30, and an overcap 40. The operating member 30 is composed of a screw-on tube 50 and an exterior tube 60. Furthermore, a solid content 2 is contained within the case tube 10.

In this embodiment, the case tube 10, the extension member 20, the threaded tube 50, the outer tube 60, and the overcap 40 share a common central axis O.

The case tube 10, the advancement member 20, and the screw tube 50 are each integrally formed by injection molding using a synthetic resin material. Note that the materials and forming methods of these components are not limited to these. However, it is preferable that these components are each integrally molded. Additionally, the exterior tube 60 and the overcap 40 are each made of metal, but may also be made of synthetic resin.

The contents 2 may be, for example, cosmetics such as lipstick, lip balm, and stick eye shadow, medicine, or stick glue that can be spread. In this embodiment, the contents 2 is a roughly cylindrical lipstick. Note that the solid contents 2 refer to those that are hard enough to retain their shape, and include those that are somewhat soft, such as semi-kneaded contents. The contents stored in the case tube 10 are exposed to the outside of the case tube 10 at the outlet 11.

The case tube 10 is cylindrical and extends along the central axis O, and has an outlet 11 at the upper end. The case tube 10 may have a tubular shape other than a cylindrical shape. In this embodiment, the outlet 11 is inclined obliquely with respect to a plane perpendicular to the central axis O, but it may be perpendicular to the central axis O.

As shown in Figures 2 and 3, a holding portion 12 is provided near the lower end of the case tube 10. The holding portion 12 is composed of an expanded diameter portion 13 in which the outer circumferential surface of the case tube 10 is expanded in diameter. The expanded diameter portion 13 is composed of an annular upper wall 13a, a cylindrical peripheral wall 13b that hangs down from the outer circumferential edge of the upper wall 13a, and an annular lower wall 13c that extends radially inward from the lower end of the peripheral wall 13b, and has a U-shaped vertical cross section all around the circumference. Note that the peripheral wall 13b may have a tubular shape other than a cylindrical shape.

The upper ends of two guide portions 14 that face each other across the central axis O are connected to the inner peripheral edge of the lower wall 13c. Each guide portion 14 extends vertically from the inner peripheral edge of the lower wall 13c to the lower end of the case tube 10, and is composed of a vertical rib 15 whose cross section is U-shaped and protrudes radially inward over its entire length. Each vertical rib 15 is composed of two side walls 15a that face each other in the circumferential direction, and an intermediate wall 15b that connects the radially inner end edges of the two side walls 15a.

As shown in Figures 1, 4, and 5, the extension member 20 is cylindrical and arranged coaxially with the central axis O of the case tube 10, and has a contents support portion 21, a screw shaft 22, and a retaining portion 23.

The content support part 21 forms the upper end of the dispensing member 20. The upper end of the content support part 21 is inclined parallel to the dispensing opening 11. When the dispensing opening 11 is provided perpendicular to the central axis O, it is preferable that the upper end of the content support part 21 is also provided perpendicular to the central axis O. The content support part 21 can slide vertically on the inner circumferential surface of the case tube 10. The content support part 21 is not limited to being cylindrical, and its shape can be changed as appropriate to match the shape of the case tube 10.

The contents 2 are stored in the case tube 10 between the dispensing opening 11 and the contents support part 21 of the dispensing member 20, and its lower part is fixed to and supported by the inner peripheral surface of the contents support part 21. By rising from the position shown in FIG. 1, the dispensing member 20 can push up the contents 2 stored inside the case tube 10 and dispense them to the outside through the dispensing opening 11.

The screw shaft 22 has an outer peripheral surface formed by a male thread 22a, and has two intermittent thread portions 22b in the form of vertical bands extending vertically over the entire length of the male thread 22a at positions facing each other across the central axis O. Each intermittent thread portion 22b is composed of a vertical groove 22c extending vertically over the entire length of the male thread 22a. Each vertical groove 22c is composed of a groove bottom surface 22d having a radial height equivalent to the bottom of the thread of the male thread 22a, and two groove side surfaces 22e formed by the circumferential end surfaces of the thread of the male thread 22a.

The two intermittent thread portions 22b are engaged with the corresponding guide portions 14 of the case cylinder 10, so that the guide portions 14 can guide the payout member 20 to move up and down while preventing it from rotating. The inner circumferential surface of the intermediate wall 15b of the vertical rib 15 of each guide portion 14 slides against the groove bottom surface 22d of the corresponding intermittent thread portion 22b, thereby forming a sliding resistance portion 16 that provides resistance to the up and down movement of the payout member 20 relative to the case cylinder 10.

The retaining portion 23 is composed of a lateral groove 23a extending in the circumferential direction. The lateral groove 23a is composed of a groove bottom surface 23b having a radial height equivalent to the bottom of the thread of the male screw 22a, an upper groove side surface 23c formed by the lower end surface of the thread of the male screw 22a, and a lower groove side surface 23d having a radial height equivalent to the thread of the male screw 22a.

A step 24 is provided between the inner circumferential surface of the content support section 21 and the inner circumferential surface of the screw shaft 22, the diameter of which decreases in a stepped manner downward.

As shown in Figures 1, 6 and 7, the threaded tube 50 is cylindrical and arranged radially outward of the screw shaft 22 coaxially with the central axis O of the case tube 10, and has a threaded tube main body 51 and multiple (four) elastic pieces 52 that extend upward from the threaded tube main body 51 and are arranged in a circumferential direction. The number and arrangement of the elastic pieces 52 can be changed as appropriate.

The threaded tube body 51 has a cylindrical tube wall 51a and an annular bottom wall 51b that extends radially inward from the lower end of the tube wall 51a. The portion of the outer peripheral surface of the tube wall 51a that spans from near the upper end to the lower portion forms a fitting guide portion 51d that is composed of multiple protruding ribs 51c that extend in the vertical direction and are aligned in the circumferential direction. In addition, the lower portion of the outer peripheral surface of the tube wall 51a forms a fitting surface 51f that is composed of a cylindrical surface 51e that has the same outer diameter as the fitting guide portion 51d.

Each elastic piece 52 has a threaded portion 52a on the upper portion of the inner circumferential surface that threads into the male thread 22a. Each threaded portion 52a is configured with a female thread 52b. In addition, the inner circumferential surface of each elastic piece 52 that spans from the upper end of the threaded portion 52a to the upper end of the elastic piece 52 is configured with an expanded inner circumferential surface 52c that is expanded in diameter more than the bottom of the thread of the female thread 52b. A protrusion 52d is provided on the outer circumferential surface of each elastic piece 52 above the threaded portion 52a.

As shown in Figures 1 and 8, the outer tube 60 is cylindrical and arranged coaxially with the central axis O of the case tube 10, and is integrated with the outer peripheral surface of the screw tube 50 by fitting. The outer tube 60 has a cylindrical outer tube main body 61 that is arranged radially outward of the holding portion 12 (expanded diameter portion 13) of the case tube 10 and fits into the fitting surface 51f of the screw tube 50, and a cylindrical reduced diameter portion 63 that is connected to the upper end of the outer tube main body 61 via a step portion 62 and has a smaller diameter than the holding portion 12 (expanded diameter portion 13).

The inner peripheral surface of the outer tube body 61 has a support surface 64 that supports the elastic piece 52 from the radially outer side via a protrusion 52d to prevent the elastic piece 52 from elastically deforming radially outward and disengaging the male thread 22a from the threaded portion 52a of the elastic piece 52. The outer peripheral surface of the outer tube body 61 forms a gripping portion 65 that can be rotated. The lower surface of the stepped portion 62 forms a stepped surface 62a that narrows in diameter upward above the threaded tube 50. The narrowing portion 63 has a number of protrusions 63a arranged in the circumferential direction to fit into the overcap 40.

As shown in FIG. 1, the holding portion 12 of the case tube 10 is disposed between the upper end surfaces of the multiple elastic pieces 52 and the step surface 62a of the outer tube 60, thereby holding the operating member 30 in a relatively rotatable manner. In addition, a portion of the case tube 10 that is located below the holding portion 12, i.e., the lower end of the case tube 10, is disposed between the expanded inner peripheral surface 52c of each elastic piece 52 and the outer peripheral surface of the screw shaft 22.

In the state shown in FIG. 1, which is the state before the content 2 is dispensed, the guide portion 14 of the case tube 10 is located at the upper end of the threaded portion 22b of the screw shaft 22. At this time, the lower end surface of the dispenser member 20 is located near the upper surface of the bottom wall 51b of the screw tube 50.

The dispensing container 1 has a nozzle insertion path P that extends through the inside of the operating member 30 and the screw shaft 22 to the inside of the content support part 21, and into which a hollow rod-shaped filling nozzle, described below, can be inserted. In other words, the nozzle insertion path P is defined by the inner peripheral surface of the bottom wall 51b of the screw tube 50 and the inner peripheral surface of the screw shaft 22. The lower end of the nozzle insertion path P may be blocked by attaching a label to the underside of the bottom wall 51b of the screw tube 50.

As shown by the two-dot chain line in FIG. 1, the overcap 40 is cylindrical with a top, including a peripheral wall 41 and a top wall 42, and is configured to cover the payout opening 11 of the case tube 10 by being detachably attached to the outer tube 60. In the state shown in FIG. 1 where the overcap 40 is attached to the outer tube 60, the inner peripheral surface of the peripheral wall 41 fits into the outer peripheral surface of the reduced diameter portion 63 of the outer tube 60, and the lower end surface of the peripheral wall 41 abuts against the upper surface of the stepped portion 62 of the outer tube 60.

As shown in FIG. 9, with the overcap 40 removed, the dispensing container 1 of this embodiment having the above configuration can dispense the contents 2 to the outside from the dispensing opening 11 of the case tube 10 by holding the case tube 10 with one hand while gripping the gripping portion 65 of the operating member 30 with the other hand and rotating it in one circumferential direction, thereby rotating the operating member 30 relative to the case tube 10 in one circumferential direction.

That is, when the operating member 30 is rotated relative to the case tube 10 in one circumferential direction, the screw portion 52a, which is a part of the operating member 30, rotates relative to the case tube 10 in one circumferential direction. The screw shaft 22, which has a male screw 22a that screws into the screw portion 52a, is prevented from rotating by the case tube 10, so when the operating member 30 is rotated relative to the case tube 10 in one circumferential direction, the screw shaft 22 rises together with the content support portion 21 relative to the case tube 10 due to the screw action of the screw portion 52a and the male screw 22a. As a result, the content 2 is pushed up by the rising content support portion 21 and is dispensed from the dispense port 11 to the outside of the case tube 10. The amount of content 2 dispensed (protruding amount) from the case tube 10 can be adjusted by the amount of relative rotation of the operating member 30. Therefore, by rotating the operating member 30 relative to the case tube 10 by a desired amount in one circumferential direction, the desired amount of contents 2 can be dispensed from the dispense opening 11 of the case tube 10 and used.

In addition, when the operating member 30 is rotated relative to the case tube 10 in the other circumferential direction, which is the opposite side to the side when the contents 2 are dispensed, the screw shaft 22 descends together with the contents support part 21 relative to the case tube 10 due to the screw action of the screw engagement part 52a and the male screw 22a. As a result, the contents 2 are pulled down by the descending contents support part 21 and fed into the inside of the case tube 10 from the feeding opening 11. Therefore, after the contents 2 are applied, the contents 2 can be fed into the inside of the case tube 10, and the contents 2 can be protected by the case tube 10. Also, when too much of the contents 2 has been dispensed, the amount of contents 2 dispensed from the case tube 10 can be adjusted by feeding the contents 2 back in.

When the propelling member 20 is moved up and down in response to a rotational operation of the operating member 30, the sliding resistance portion 16 provides an appropriate sliding resistance between the case tube 10 and the propelling member 20. By providing the sliding resistance portion 16 in this manner, it is possible to easily set an appropriate resistance to the movement of the propelling member 20 in response to a rotational operation of the operating member 30.

As shown in FIG. 9, when the maximum amount of contents 2 has been dispensed, the screwing portion 52a reaches inside the retaining portion 23 of the screw shaft 22, and the screwing portion 52a and the male screw 22a are disengaged. Therefore, even if the operating member 30 is further rotated relative to the case tube 10 in one circumferential direction, the screw shaft 22 will not rise any further, and this prevents the dispensing member 20 from falling out of the dispensing opening 11 of the case tube 10.

The dispensing container 1 of this embodiment can be assembled, for example, as shown in Figures 10 to 13.

First, as shown in FIG. 10, the payout member 20 is attached to the jig 3. The jig 3 has a disk-shaped base 3b, the bottom surface 3a of which serves as the mounting surface, and a cylindrical shaft portion 3c that is smaller in diameter than the base 3b and extends upward from the upper surface of the base 3b. The shaft portion 3c also has a step portion 3d that reduces in diameter in a stepped manner upward. Therefore, the payout member 20 in an inverted position can be attached to the jig 3 by assembling it from above to the jig 3 in an upright position and abutting the step portion 24 of the payout member 20 against the step portion 3d of the jig 3.

Next, as shown in Figure 11, the case cylinder 10 in an inverted position is assembled from above. Specifically, the case cylinder 10 can be assembled by abutting the guide portion 14 of the case cylinder 10 against the upper end (the lower end in the vertical direction during this assembly) of the vertical groove 22c that constitutes the intermittent thread portion 22b of the payout member 20.

Then, as shown in FIG. 12, the threaded tube 50 is assembled from above in an inverted position. The threaded tube 50 has threaded portions 52a that thread into the male threads 22a of the screw shaft 22, but each threaded portion 52a can be displaced radially due to the elastic deformation of the elastic pieces 52, and can be unscrewed from the male threads 22a. Therefore, by simply pushing the threaded tube 50 straight down without rotating it downward, the threaded tube 50 can be pushed down until the upper end surface of the elastic pieces 52 (the lower end surface in the vertical direction during this assembly) abuts against the enlarged diameter portion 13 (retaining portion 12) of the case tube 10, completing the assembly of the threaded tube 50.

Then, as shown in FIG. 13, the jig 3 is removed, the assembly is brought into an upright position, and the upright outer tube 60 is then attached from above. Specifically, the outer tube 60 can be attached by abutting the step surface 62a of the outer tube 60 against the upper surface of the enlarged diameter portion 13 (holding portion 12) of the case tube 10. This assembly causes the outer tube 60 to fit into the fitting guide portion 51d and the fitting surface 51f of the threaded tube main body 51, and to become integrated with the threaded tube main body 51. At this time, as the outer tube 60 descends, it first slides downward on the fitting guide portion 51d, but since the fitting guide portion 51d is composed of multiple protruding ribs 51c, the sliding resistance is suppressed, and the outer tube 60 can be smoothly lowered to fit into the fitting surface 51f.

By assembling the outer tube 60, the elastic piece 52 comes into contact with the support surface 64 of the outer tube 60 via the protrusion 52d and is supported from the radially outward side. This prevents the elastic piece 52 from elastically deforming radially outward and disengaging the screw portion 52a from the male screw 22a.

When the dispensing container 1 is assembled in this manner, the contents 2 are filled inside the contents support portion 21 and the portion of the case tube 10 above it before the overcap 40 is attached. This filling process can be carried out, for example, as follows.

First, the dispensing port 11 is closed with a cap body (not shown) and the dispensing container 1 is placed in an inverted position. Next, a hollow rod-shaped filling nozzle (not shown) is inserted vertically from above into the nozzle insertion path P. Then, with the filling nozzle's discharge port positioned, for example, within the content support portion 21, fluid, high-temperature content 2 is discharged, filling the inside of the content support portion 21 and the portion of the case tube 10 above it (vertically below). The content 2 is then cooled and solidified, and the cap body is removed.

The dispensing container 1 of this embodiment is configured so that the dispensing member 20 and the operating member 30 are screwed together without going through the case tube 10, so that the radial size of the dispensing container 1 can be easily reduced. In addition, the dispensing container 1 of this embodiment is configured so that the multiple elastic pieces 52 can be elastically deformed in the radial direction to disengage the screwing portion 52a from the male thread 22a during assembly, so that easy assembly can be achieved by assembling the screwing tube 50 straight without rotating it.

The dispensing container 1 of the present embodiment described above has a nozzle insertion path P to enable back-filling, in which the contents 2 are filled from below, rather than from the side of the dispensing opening 11. However, this is not limited to this, and for example, as in the modified example shown in FIG. 14, the contents support part 21 may have a bottom wall 21a, and therefore may not have a nozzle insertion path P, and the contents 2 may be filled from the side of the dispensing opening 11. Note that in FIG. 14, elements corresponding to those shown in FIGS. 1 to 13 are given the same reference numerals.

In addition, in the first embodiment of the dispensing container 1, the holding portion 12 is configured with an expanded diameter portion 13 having a U-shaped cross section around the entire circumference, and each guide portion 14 is configured with a vertical rib 15, but the holding portion 12 and each guide portion 14 may be configured as in the second embodiment shown in Figures 15 to 19. Note that in Figures 15 to 19, elements corresponding to those shown in Figures 1 to 13 are given the same reference numerals.

In the second embodiment, as shown in FIG. 15, the outer tube 60 and the overcap 40 are made of synthetic resin, but otherwise have the same configuration as the first embodiment. Also, as shown in FIG. 15 and FIG. 18(a)-(c), the propelling member 20 has the same configuration as the first embodiment. In this embodiment, the two intermittent threaded portions 22b have different circumferential widths, and the two guide portions 14 also have different circumferential widths (see FIG. 17), but this is not limited thereto, and the two intermittent threaded portions 22b and the two guide portions 14 may each have the same width. By making the widths different as described above, it is possible to prevent erroneous assembly in which the upper end inclined surfaces do not match when assembling the case tube 10 and the propelling member 20. Also, in the first embodiment, the widths may be made different as in this embodiment. Also, the screw tube 50 has the same configuration as the first embodiment. The case tube 10 has the same configuration as the first embodiment, except for the holding portion 12 and the two guide portions 14.

As shown in Figures 15 to 17, in this embodiment, the holding portion 12 is provided at the lower end of the case tube 10. The holding portion 12 is configured as an expanded diameter portion 13 in which the outer circumferential surface of the case tube 10 is expanded in diameter. In this embodiment, the inner circumferential surface of the expanded diameter portion 13 has the same inner diameter as the inner circumferential surface of the case tube 10 above the expanded diameter portion 13 except for the lower portion, and is expanded in diameter at the lower portion. In addition, the upper portion of the outer circumferential surface of the expanded diameter portion 13 is provided with a plurality of recesses 13d arranged intermittently in the circumferential direction. The lower portion of the outer circumferential surface of the expanded diameter portion 13 is provided with a plurality of protrusions 13e arranged intermittently in the circumferential direction. The plurality of recesses 13d and the plurality of protrusions 13e reduce the sliding resistance between the expanded diameter portion 13 and the outer tube 60.

As in the first embodiment, the holding portion 12 is disposed between the upper end surfaces of the multiple elastic pieces 52 and the step surface 62a of the outer tube 60, thereby holding the operating member 30 in a relatively rotatable manner.

In this embodiment, each guide portion 14 is formed of a protrusion 17 that protrudes radially inward from the inner peripheral surface of the enlarged diameter portion 13 and extends downward. The inner peripheral surface of the lower end of each protrusion 17 forms a sliding resistance portion 16.

As in the first embodiment, each guide portion 14 engages with a corresponding intermittent thread portion 22b, so that the guide portion 14 can guide the payout member 20 to move vertically while being prevented from rotating (see Figures 15 and 19).

Also, as in the first embodiment, each sliding resistance portion 16 can provide resistance to the vertical movement of the payout member 20 relative to the case tube 10 by sliding against the groove bottom surface 22d of the corresponding intermittent thread portion 22b. Therefore, when the payout member 20 is moved vertically in response to a rotation operation of the operating member 30, an appropriate sliding resistance is provided between the case tube 10 and the payout member 20 by the sliding resistance portion 16. By providing the sliding resistance portion 16 in this manner, an appropriate resistance can be easily set to the movement of the payout member 20 in response to a rotation operation of the operating member 30.

This embodiment can be used and assembled in the same manner as the first embodiment. This embodiment can also provide the same effects as the first embodiment.

The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the invention.

Therefore, the dispensing container 1 of the above embodiment can be modified in various ways, for example as described below.

The dispensing container 1 of the above embodiment has a case tube 10 with a dispensing opening 11 at the upper end, a screw shaft 22 with an outer circumferential surface formed by a male screw 22a, a dispensing member 20 that is arranged radially inside the case tube 10 in a manner that allows it to move vertically while being prevented from rotating, and supports the contents 2, a screw tube 50 that is arranged radially outside the screw shaft 22, and an operating member 30 that has an outer tube 60 that is integrated with the outer circumferential surface of the screw tube 50 by fitting, and the screw tube 50 is a cylindrical Various modifications are possible as long as it has a threaded tube body 51, an elastic piece 52 that extends upward from the threaded tube body 51 and threads into the male thread 22a, the inner circumferential surface of the outer tube 60 has a support surface 64 that supports the elastic piece 52 from the outside in the radial direction, and a step surface 62a that narrows in a stepped shape upward above the threaded tube 50, and the case tube 10 has a holding portion 12 that is positioned between the upper surface of the elastic piece 52 and the step surface 62a of the outer tube 60 to hold the operating member 30 in a relatively rotatable manner.
