DETAILED DESCRIPTION OF THE INVENTION

[0016] Various embodiments of the present disclosure will be described in detail below with reference to the drawings. In this specification, claims, abstract, and drawings, the side where a lid 40 (described later) is located is referred to as the upper side (upper side in FIG. 1, the positive Z-axis direction), and the side where an operating unit 50 is provided is referred to as the lower side (lower side in FIG. 1, the negative Z-axis direction). The front-rear direction is the direction perpendicular to the plane of FIG. 1 (the Y-axis direction) and the left-right direction in FIG. 2. The left-right direction is the left-right direction in FIG. 1 (the X-axis direction) and the direction perpendicular to the plane of FIG. 2. The radially outward direction refers to the direction away from the central axis O along a straight line passing through the central axis O of the propelling container 100 and perpendicular to the central axis O, which is aligned in the up-down direction in FIG. 1. The radially inward direction refers to the direction toward the central axis O along this straight line. The major axis direction and the minor axis direction are also considered to be radial directions. The circumferential direction refers to the direction of rotation around the central axis O.

[0017] The accompanying drawings of the present disclosure are drawn to equal scale in the up-down, front-back, and left-right directions, and the aspect ratio of the dispensing container 100 in the drawings represents the aspect ratio of the dispensing container 100 of the present disclosure. However, the configuration, shape, dimensional ratio, etc. of the dispensing container 100 in the accompanying drawings are merely one embodiment of the present disclosure. The present disclosure should be interpreted based on the wording of the claims, and is not limited to the configuration, shape, dimensional ratio, etc. shown in the drawings.

[0018] FIG. 1 shows a dispensing container 100 according to a first embodiment of the present disclosure. The dispensing container 100 according to this embodiment includes a cylindrical container body 10 with a bottom and an opening 13b at its upper end, a central tray 20 disposed within the container body 10 and supported so as to be vertically movable relative to the container body 10, a rotating shaft 30 extending vertically, supporting the central tray 20 at its upper end and capable of driving the central tray 20 vertically, a lid 40 closing the opening 13b at the upper end of the container body 10, a base 60 on which the container body 10 is placed, a flat-shaped sliding member 70 movable in the longitudinal direction relative to the base 60, and an operating unit 50 disposed below the base 60 and rotating in synchronization with the rotating shaft 30. The dispensing container 100 according to this embodiment contains a rod-shaped content, such as cosmetics (lipstick, lip balm, or eyeshadow stick), glue, or medicine, and allows a user to dispense only the required amount of the content. In this embodiment, the container body 10 has a flat shape in a plan view.

[0019] 1 and 2, the container body 10 includes a major axis sidewall 11a and a minor axis sidewall 11b having an opening 13b at the upper end and a substantially rectangular flat shape with rounded corners in a plan view, a bottom wall 13 closing the lower ends of the sidewalls, a support wall 15 hanging down from the vicinity of the major axis outer edge of the bottom wall 13, an inner cylindrical portion 17 hanging down from the radially inner end of the bottom wall 13, and an inclined portion 18 inclined downward and radially outward (outward in the major axis direction) from the bottom wall 13. Here, the major axis sidewall 11a refers to the sidewall of the container body 10 that constitutes the major axis (long side) end (the left-right direction in FIG. 1, the direction perpendicular to the paper surface in FIG. 2, the X-axis direction) of the substantially rectangular shape in a plan view, and the minor axis sidewall 11b refers to the sidewall that constitutes the minor axis (short side) end (the direction perpendicular to the paper surface in FIG. 1, the left-right direction in FIG. 2, the Y-axis direction) of the substantially rectangular shape. The following terms shall be interpreted in the same manner.

[0020] 1 and 3, when the container body 10 is set on the base 60, the support wall 15 is engaged with the base longitudinal side wall 61a of the base 60 through an undercut to fix the container body 10 to the base 60. Furthermore, by fixing the support wall 15 to the base longitudinal side wall 61a of the base 60, circumferential rotation of the container body 10 relative to the base 60 is restricted.

[0021] 1 and 5A to 5D, inclined portion 18 is provided via connecting wall 18a hanging down from bottom wall 13, and is inclined downward and outward in the longitudinal direction. As shown in Fig. 4 and 5A to 5D, inclined portion 18 includes inclined-portion main wall 18e1 that extends at an angle downward and outward in the longitudinal direction in a front view, inclined-portion bottom wall 18c that extends horizontally from the lower end of inclined-portion main wall 18e1 further outward in the longitudinal direction, inclined-portion side walls 18b provided at both ends of inclined-portion main wall 18e1 in the Y-axis direction (left-right direction in Fig. 4), and lower protrusion 18e2 provided at the lower end of inclined-portion main wall 18e1 (the upper surface of inclined-portion bottom wall 18c).

[0022] As will be described later, when the undercut engagement between the container body 10 and the base 60 is released and the container body 10 is moved upwardly away from the base 60, as shown in Figures 5A to 5D, the lower protrusion 18e2 on the longitudinal outer side of the inclined portion 18 abuts against the opening outer end 72b of the engagement opening 72 of the slide member 70, and the slide member 70 moves outward in the longitudinal direction. This releases the threaded engagement between the female threaded portion 78a of the slide member 70 and the male threaded portion 31a of the rotation shaft 30. In this embodiment, as shown in Figures 5A to 5D, when the inclined portion 18 abuts against the opening outer end 72b of the engagement opening 72, the protrusion inclined surface 18e3 provided on the lower protrusion 18e2 abuts against the outer end inclined surface 72b1 provided on the opening outer end 72b and substantially parallel to the protrusion inclined surface 18e3. With this configuration, the inclined portion 18 and the opening outer end portion 72b are in surface contact with each other while driving the slide member 70 outward in the longitudinal direction, thereby enabling smooth movement of the slide member 70. The container body 10 can be made of various synthetic resins as well as metal materials such as aluminum.

[0023] The intermediate dish body 20 comprises a dish bottom wall 23 that supports, for example, rod-shaped contents (not shown), a major axis peripheral wall 21a and a minor axis peripheral wall 21b that extend upward from the outer periphery of the dish bottom wall 23, a bottom cylindrical portion 25 that hangs down from the radially inner side of the dish bottom wall 23, and a central convex wall 23b that has an upwardly convex shape on the radially inner side of the bottom cylindrical portion 25.

[0024] The inner plate 20 has a flat, generally rectangular shape in plan view and supports a rod-shaped content (not shown) from below, which also has a flat shape in plan view. As described below, the inner plate 20 can move up and down within the container body 10 in conjunction with the vertical movement of the rotating shaft 30. That is, when the rotating shaft 30 is raised by rotating the operating unit 50, the engaging protrusions 35a protruding radially outward from the shaft top 35 of the rotating shaft 30 engage with the engaging claws 25a on the inner surface of the bottom tube 25, driving the inner plate 20 and moving it upward. The inner plate 20 can also be moved downward by rotating the operating unit 50 in the reverse direction.

[0025] As shown in Figures 1, 2, etc., the intermediate plate body 20 has a major axis peripheral wall 21a and a minor axis peripheral wall 21b that correspond to the flat shape of the major axis side wall 11a and minor axis side wall 11b of the container body 10 in a planar view, and is unable to rotate around the central axis O relative to the container body 10.

[0026] 1, at the lowest point of the movable range of the inner plate 20, the engaging projection 11a1 provided on the inner surface of the longitudinal side wall 11a of the container body 10 is engaged with the engaging projection 21a1 provided on the longitudinal peripheral wall 21a of the inner plate 20 through undercut engagement (in this state, the leg 23h of the inner plate 20 abuts on the upper surface of the bottom wall 13 of the container body 10). When the user rotates the operating unit 50 around the central axis O and the inner plate 20 is pressed upward by the rotating shaft 30, the fitting projection 35a protruding radially outward from the shaft top 35 of the rotating shaft 30 first fits into the fitting claw 25a on the inner surface of the bottom tube portion 25.

[0027] In this embodiment, the upward separation force to be applied to the middle plate body 20 to disengage the peripheral wall (longitudinal peripheral wall 21a) of the middle plate body 20 from the side wall (longitudinal side wall 11a) of the container body 10 is configured to be greater than the upward engagement force to be applied to the rotating shaft 30 to engage the lower part (bottom tube part 25) of the middle plate body 20 with the upper part (shaft top part 35) of the rotating shaft 30. Therefore, when the rotating shaft 30 is rotated around the central axis O and moved upward by rotating the operating part 50, the bottom tube part 25 of the middle plate body 20 and the shaft top part 35 of the rotating shaft 30 engage with each other before the longitudinal peripheral wall 21a of the middle plate body 20 and the longitudinal side wall 11a of the container body 10 are disengaged (from the state shown in Figure 1, the engaging protrusion 35a of the shaft top part 35 overcomes the engaging claws 25a of the bottom tube part 25, and the shaft top part 35 engages even deeper inside the bottom tube part 25).

[0028] After the shaft top 35 of the rotating shaft 30 is engaged with the bottom cylindrical portion 25 of the inner plate 20 by rotating the operating unit 50, further rotation of the operating unit 50 causes the rotating shaft 30 to further press the inner plate 20 upward while the shaft top 35 of the rotating shaft 30 remains engaged with the bottom cylindrical portion 25 of the inner plate 20. As a result, the engagement between the longitudinal peripheral wall 21a of the inner plate 20 and the longitudinal side wall 11a of the container body 10 is released, and the inner plate 20 is released upward from the container body 10. At this time, the leg portion 23h of the inner plate 20 also moves upward away from the bottom wall 13 of the container body 10. As a result, the inner plate 20 is extended upward.

[0029] In this embodiment, as shown in FIG. 1 , an annular thin-walled portion 23a is provided radially outward of the bottom tubular portion 25 and the central protruding wall 23b of the inner plate 20. Here, the thin-walled portion 23a is formed thinner than the other portions of the bottom wall 23. That is, the bottom tubular portion 25 is connected to the bottom wall 23 of the inner plate 20 via the thin-walled portion 23a provided in the bottom wall 23 of the inner plate 20. With this configuration, the thin-walled portion 23a of the bottom wall 23 has low bending rigidity. Therefore, when the shaft top 35 of the rotating shaft 30 fits inside the bottom tubular portion 25 of the inner plate 20, the thin-walled portion 23a bends more easily than the other portions of the bottom wall 23, and the lower end of the bottom tubular portion 25 is easily displaced outward. Therefore, the shaft top 35 fits easily inside the bottom tubular portion 25 of the inner plate 20.

[0030] As described above, when the engagement (undercut engagement) between the longitudinal peripheral wall 21a of the inner plate 20 and the longitudinal side wall 11a of the container body 10 is released, the inner plate 20 is extended further upward. The material of the inner plate 20 can be various synthetic resins or metal materials such as aluminum.

[0031] As for the materials constituting the members other than the container body 10 and the inner plate body 20, it is desirable to use various synthetic resin materials, but the materials are not limited to these.

[0032] As shown in FIGS. 1 and 2, the rotating shaft 30 includes a rotating cylinder portion 31 extending vertically along the central axis O, and arm portions 33 extending from the lower portion of the rotating cylinder portion 31 toward the outside in the longitudinal direction of the operating unit 50. The outer peripheral surface of the rotating cylinder portion 31 is provided with a male thread portion 31a that can be threadedly engaged with a female thread portion 78a provided on the inner peripheral surface of the slide member 70. The shaft top portion 35 at the upper end of the rotating cylinder portion 31 abuts against the bottom cylinder portion 25 of the central plate body 20 as the rotating shaft 30 rises, thereby moving the central plate body 20 upward. As shown in FIG. 1, two fitting recesses 33a extending vertically are provided radially outward of each of the two arms 33 extending on both sides in the longitudinal direction, facing the operating unit main body 51 of the operating unit 50, as shown in FIG. 1 and other figures. A first engagement rail 51d provided on the inner surface of the short-axis direction operation wall 51b of the operation unit main body 51 and a second engagement rail 55d provided on the inner surface of the cover side wall 55a of the operation unit cover 55 are fitted into these two fitting recesses 33a. With this configuration, when the operation unit main body 51 (operation unit 50) is rotated around the central axis O by operation by the user, the rotation of the operation unit 50 is transmitted to the rotation shaft 30 via the arm part 33, and the rotation shaft 30 also rotates around the central axis O.

[0033] The operating unit 50 is attached to the lower part of the base 60 (described later) in a state in which it can rotate relatively about the central axis O. The operating unit 50 includes a cylindrical operating unit main body 51 with a bottom, and an operating unit cover 55 that closes the upper opening of the operating unit main body 51. The operating unit main body 51 has a flat shape that is generally rectangular in shape with a major axis (long side) direction and a minor axis (short side) direction in a plan view, and has substantially the same shape as the lid body 40 (described later) (in FIGS. 1 and 2, the outer surfaces of the lid body 40 and the operating unit main body 51 are generally flush with each other). With this configuration, the operating unit 50 of the dispensing container 100 does not have to be provided with circumferential irregularities like conventional dispensing containers, but the flat outer peripheral surface of the operating unit 50 makes it easy to rotate the operating unit 50 circumferentially about the central axis O without the hand slipping. Therefore, there is no need to provide unevenness on the outer surface of the dispensing container 100, which makes it possible to expand the decorative area on the outer surface of the dispensing container 100 and to make it easier to improve the appearance of the dispensing container 100.

[0034] The operation unit main body 51 includes a long-axis operation wall 51a and a short-axis operation wall 51b, which are operation walls (side walls) having a flat shape in a plan view, and an operation unit bottom wall 51c that closes the lower end of the operation wall. A first engagement rail 51d that protrudes radially inward is provided on the inner surface of the short-axis operation wall 51b and fits into a fitting recess 33a provided in the arm portion 33 of the above-mentioned rotation shaft 30. The first engagement rail 51d extends vertically along the central axis O, and supports the rotation shaft 30 non-rotatably with respect to the operation unit 50, guiding the rotation shaft 30 vertically along the first engagement rail 51d.

[0035] An operation unit cover 55 is disposed above the operation unit main body 51 to cover the upper opening of the operation unit main body 51. The operation unit cover 55 includes a cover side wall 55a having a flat shape in a plan view that is fitted and fixed to the inner surfaces of the operation walls (long-axis direction operation wall 51a and short-axis direction operation wall 51b) of the operation unit main body 51, a cover top wall 55b that closes the upper end of the cover side wall 55a, and a cover inner cylinder 55e that hangs down from the radially inner end of the cover top wall 55b. Similar to the short-axis direction operation wall 51b described above, a second engagement rail 55d that protrudes radially inward is provided on the inner surface of the cover side wall 55a. The second engagement rail 55d fits into a fitting recess 33a provided in the arm portion 33 of the rotation shaft 30. The second engagement rail 55d extends vertically along the central axis O in order to guide the rotating shaft 30 from the lower end to the upper end of the movable range by combining with the first engagement rail 51d, and guides the rotating shaft 30 vertically along this second engagement rail 55d while supporting it so that it cannot rotate relative to the operating unit 50.

[0036] 1, the cover inner cylinder 55e engages with an engaging claw portion 67a of a sliding inner wall 67 that hangs down from the radially inner end of a base portion 68 of the base 60 (described later), and is attached so as to be slidable in the circumferential direction relative to the outer peripheral surface of the sliding inner wall 67. With this configuration, the operating unit 50 is supported so as to be rotatable relative to the base 60 around the central axis O.

[0037] As shown in Figure 3, the base 60 has a flat shape that is approximately rectangular in a plan view, and is equipped with side walls (base long axis side wall 61a and base short axis side wall 61b), a base base 68 that is connected to the lower end of the side walls and is positioned directly above the cover top wall 55b of the operating unit cover 55, and a sliding inner wall 67 that hangs down from the radially inner end of the base base 68 of the base 60.

[0038] A support wall 15 hanging down from the bottom wall 13 of the container body 10 is fixed by undercut engagement to the radially inner side of the pedestal longitudinal side wall 61a of the pedestal 60. In addition, a slide member 70, which will be described later, is placed on the pedestal base 68.

[0039] The cover inner cylinder 55e of the operation unit cover 55 engages with the outer surface of the sliding inner wall 67, and the cover inner cylinder 55e is attached to the outer peripheral surface of the sliding inner wall 67 so as to be slidable (rotatable) about the central axis O. With this configuration, the operation unit 50 is supported so as to be rotatable relative to the base 60 about the central axis O.

[0040] As shown in FIG. 1 and other figures, the sliding member 70 includes a sliding top wall 71, a sliding outer wall 73 hanging down from the radially outer end (longitudinal direction) of the sliding top wall 71, a female thread portion 78a formed on the inner surface of a sliding inner wall 78 provided at the radially inner end of the sliding top wall 71, and minor axis direction side walls 77 (see FIG. 4) hanging down from the sliding top wall 71 on both sides in the minor axis direction (circumferential direction) of the sliding top wall 71. An engagement opening 72 is formed in the sliding top wall 71 to receive the inclined portion 18 of the container body 10. The engagement opening 72 includes an opening inner end portion 72a hanging down from the radially inner end (longitudinal direction) and an opening outer end portion 72b integrally formed with the sliding outer wall 73 at the radially outer end (longitudinal direction). The radial (longitudinal direction) width of the engagement opening 72 is configured to be narrower than the major axis direction width of the inclined portion 18. This configuration allows the container body 10 to be separated from the base 60 and the slide member 70, and also allows the slide member 70 to move smoothly when placed on the base 60 and the slide member 70.

[0041] 5A to 5D, an inner end inclined surface 72a1 is formed at the upper part of the opening inner end 72a, and the inner end inclined surface 72a1 is arranged substantially parallel to the inclined portion main wall 18e1 of the inclined portion 18. Similarly, an outer end inclined surface 72b1 is formed at the lower part of the opening outer end 72b, and the outer end inclined surface 72b1 is arranged substantially parallel to the inclined portion main wall 18e1 and the protruding inclined surface 18e3 of the inclined portion 18.

[0042] With the above configuration, when the undercut engagement between the container body 10 and the base 60 is released and the container body 10 is moved upward away from the base 60, as shown in FIGS. 5A to 5D , the protrusion inclined surface 18e3 of the lower protrusion 18e2 of the inclined portion 18 abuts against the outer end inclined surface 72b1 of the opening outer end 72b, and the slide member 70 moves outward in the longitudinal direction relative to the container body 10. This releases the threaded engagement between the female threaded portion 78a of the slide member 70 and the male threaded portion 31a of the rotation shaft 30. In this embodiment, the protrusion inclined surface 18e3 and the outer end inclined surface 72b1, which are arranged substantially parallel to each other, are configured to abut against each other, driving the slide member 70 outward in the longitudinal direction while the inclined portion 18 and the opening outer end 72b are in surface contact. This allows the slide member 70 to move smoothly outward in the longitudinal direction.

[0043] As is clear from a comparison of FIGS. 5A and 5D, in this embodiment, when the container body 10 is lifted upward by a distance h from the state in which it is placed on the base 60 and the slide member 70, the slide member 70 is configured to move a distance d outward in the radial direction (longitudinal direction) (in FIG. 5D, the state in which the container body 10 is placed on the base 60 and the slide member 70 is shown by a two-dot chain line). The relationship between h and d depends on the inclination angle of the inclined portion 18. In this embodiment, the distance d is configured to be greater than (outer diameter - minor diameter) / 2 of the male thread portion 31a. With this configuration, when the slide member 70 is moved radially (longitudinal direction) outward by a distance d, the female thread portion 78a is reliably disengaged from the male thread portion 31a.

[0044] In this embodiment, the operation of moving the container body 10 upward from the base 60 causes the slide member 70 to move radially (longitudinal) outward. At this time, the state transitions from one in which the engagement protrusion 77a provided on the minor axis direction sidewall 77 of the slide member 70 is radially inward of the engagement protrusion 61b1 provided on the minor axis direction sidewall 61b of the base 60 side shown in FIGS. 6A and 6B to one in which the engagement protrusion 77a of the slide member 70 is radially outward of the engagement protrusion 61b1 on the base 60 side shown in FIGS. 7A and 7B. Due to the undercut engagement between the engagement protrusion 77a and the engagement protrusion 61b1 shown in FIGS. 7A and 7B, even when the container body 10 is completely removed from the base 60, the slide member 70 is locked in the radial (longitudinal) position shown in FIGS. 7A and 7B. Therefore, the thread engagement between the female thread portion 78a of the slide member 70 and the male thread portion 31a of the rotation shaft 30 can be maintained in a released state. In this specification and claims, the term "lock" broadly means that one element acts on another element to stop its movement.

[0045] The manner in which the slide member 70 is locked radially outward when the container body 10 is moved upwardly away from the base 60 is not limited to the above-described manner. For example, a rib extending in the vertical direction may be provided on the side surface of the slide member 70 in the minor axis direction, and this rib may come into surface contact with a rib provided on the inner surface of the base minor axis side wall 61b of the base 60, so that the slide member 70 is locked to the base 60 by frictional force.

[0046] On the other hand, when the container body 10 is placed on the base 60 and the container body 10 and base 60 are undercut engaged, the container body 10 moves from Fig. 5D to Fig. 5C, and the lower surface of the main inclined portion wall 18e1 of the inclined portion 18 abuts against the inner end inclined surface 72a1 of the opening inner end 72a. As a result, the lower surface of the main inclined portion wall 18e1 and the inner end inclined surface 72a1, which are provided substantially parallel to each other, abut against each other, so that the slide member 70 is pressed by the surface, allowing smooth movement inward in the radial direction (longitudinal direction). When the slide member 70 moves inward in the radial direction (longitudinal direction), the female thread portion 78a of the slide member 70 again threadably engages with the male thread portion 31a of the rotation shaft 30. With this configuration, when the container body 10 is placed on the base 60, the male threaded portion 31a of the rotating shaft 30 and the female threaded portion 78a of the sliding member 70 are threadedly engaged, so that the rotating shaft 30 can move upward relative to the sliding member 70 as it rotates around its own central axis O.

[0047] As shown in Fig. 2, the minor axis direction side wall 77 is provided with an engaging claw 77b that protrudes outward in the minor axis direction. As shown in Fig. 2, the engaging claw 77b is engaged with and fixed to an engaging protrusion 61b2 on the base minor axis direction side wall 61b of the base 60. When fixing the slide member 70, the slide member 70 can be mounted by placing the slide member 70 inside the base 60 from above in Fig. 1 and then undercut-engaging the engaging claw 77b with the engaging protrusion 61b2 on the base minor axis direction side wall 61b.

[0048] As shown in FIGS. 1 and 2, the lid 40 has a cylindrical shape with a top and closes the opening 13b at the upper end of the container body 10. The lid 40 has a flat shape that is generally rectangular in plan view, and includes lid side walls (longitudinal lid side walls 41 and minor axial lid side walls 42) and a top wall 43 that is continuous with the upper ends of the lid side walls. The lid 40 has generally the same shape as the operating unit 50 in plan view (in FIGS. 1 and 2, the outer surfaces of the lid 40 and the operating unit main body 51 are generally flush with each other). In addition, the lower inner surfaces of the longitudinal axial lid side walls 41 and minor axial lid side walls 42 of the lid 40 have generally the same shape as the upper outer surface of the cover side wall 55a of the operating unit cover 55, as shown in FIGS. 1 and 2. The lid body 40 is removably fixed by undercut engagement of the annular protrusion on the inner surface of the lid body side wall with the base engagement claw 61a1 on the outer surface of the base longitudinal axis side wall 61a of the base 60 described later.

[0049] In this embodiment, as shown in FIG. 1 and other figures, when the lid 40 is attached, the lid 40 engages with both the base 60 and the operating unit 50 (the lower portions of the major axis lid sidewall 41 and the minor axis lid sidewall 42 of the lid 40 cover the outer peripheral surface of the base 60 and the outer peripheral surface of the upper portion of the operating unit 50). Therefore, the operating unit 50 cannot be rotated around the central axis O relative to the base 60. This is because the base 60 and the operating unit 50, both of which have flat shapes, are covered from the radial outside by the lid 40, which also has a flat shape, preventing relative rotation in the circumferential direction. Therefore, when the lid 40 is attached, it is possible to prevent the inner tray 20 and contents from being unintentionally advanced by the user.

[0050] With the above configuration, when the cover 40 is attached, it is necessary to align the long axis direction of the base 60 with the long axis direction of the operation unit 50 in advance.

[0051] When using the dispensing container 100 having such a configuration, the user first grasps the lid body side wall (normally, the short-axis lid side wall 42) of the lid body 40 from the state shown in Figure 1 and pulls it upward, opening the opening 13b at the upper end of the container body 10 and exposing the contents. Next, the user grasps the outer peripheral surface of the base 60 (normally, the outer peripheral surface of the base short-axis side wall 61b) with one hand and grasps the operating wall of the operating unit body 51 (normally, the short-axis operating wall 51b) with the other hand, and rotates it around the central axis O.

[0052] By rotating the operation unit main body 51 about the central axis O relative to the base 60, the arm portion 33 of the rotating shaft 30, which is engaged with the first engagement rail 51d and the second engagement rail 55d provided on the inner surface of the short-axis direction operation wall 51b and the cover side wall 55a of the operation unit main body 51, rotates together with the operation unit 50. As a result, the rotating shaft 30 rotates relative to the base 60, and the rotating shaft 30 also rotates relative to the female thread portion 78a of the slide member 70 fixed to the base 60, and the male thread portion 31a engages with the female thread portion 78a, causing the rotating shaft 30 to move upward relative to the base 60 and the slide member 70.

[0053] When the rotating shaft 30 moves upward relative to the base 60 and the sliding member 70, the shaft apex 35 at the upper end of the rotating shaft 30 fits inside the bottom tube portion 25 of the inner plate 20, pushing the inner plate 20 upward. As the rotating shaft 30 pushes the inner plate 20 upward, the engagement between the engaging protrusions 11a1 provided on the longitudinal side wall 11a of the container body 10 and the longitudinal peripheral wall 21a of the inner plate 20 is released, and the inner plate 20 is extended upward to the top dead center.

[0054] In this embodiment, the shaft apex 35 at the upper end of the rotating shaft 30 fits inside the bottom tube portion 25 of the inner plate 20, and the upper surface of the shaft apex 35 abuts against the lower surface of the central convex wall 23b of the inner plate 20. In this embodiment, the upper surface of the shaft apex 35 and the lower surface of the central convex wall 23b both have substantially the same dish shape that is convex upward. Therefore, the upper surface of the shaft apex 35 and the lower surface of the central convex wall 23b can be in surface contact, allowing the inner plate 20 to be advanced upward by the rotating shaft 30 in a stable position.

[0055] When the rod-shaped contents fixed to the inner plate 20 are used up, the user moves the container body 10 and the inner plate 20 upward and removes them from the base 60. As a result, as shown in FIGS. 5A to 5D , the lower protrusion 18e2 on the longitudinal outer side of the inclined portion 18 abuts against the opening outer end 72b of the engagement opening 72 of the slide member 70, and the slide member 70 moves outward in the longitudinal direction. This releases the threaded engagement between the female threaded portion 78a of the slide member 70 and the male threaded portion 31a of the rotation shaft 30. In this embodiment, as shown in FIGS. 5A to 5D , when the inclined portion 18 abuts against the opening outer end 72b of the engagement opening 72, the protrusion inclined surface 18e3 provided on the lower protrusion 18e2 abuts against the outer end inclined surface 72b1 provided on the opening outer end 72b and substantially parallel to the protrusion inclined surface 18e3. With this configuration, the inclined portion 18 and the opening outer end portion 72b are in surface contact with each other while driving the slide member 70 outward in the longitudinal direction, so that the slide member 70 can be moved smoothly.

[0056] By releasing the thread engagement between the female thread portion 78a and the male thread portion 31a, the rotating shaft 30, which had moved to top dead center, moves to bottom dead center. In this embodiment, the rotating shaft 30 is automatically moved to bottom dead center by separating the container body 10 from the base 60. This eliminates the need to return the rotating shaft 30, which has been extended to top dead center due to the use of the contents, to its original position. Then, once the rotating shaft 30 has moved to bottom dead center, the contents of the new cartridge can be used simply by placing a new cartridge (the inner plate 20 and the container body 10 that hold the new contents) on the base 60. This improves the ease of replacing a used cartridge with a new one.

[0057] As described above, this embodiment is a dispensing container 100 for dispensing contents from a container body 10, and includes: a container body 10 that has a flat shape in a plan view and is a cylindrical container body with a bottom and an opening 13b at its top; an inner plate 20 that is disposed within the container body 10 and supported so as to be movable in the vertical direction relative to the container body 10; a rotating shaft 30 that extends in the vertical direction and is capable of driving the inner plate 20 in the vertical direction; a base 60 that has a flat shape in a plan view and on which the container body 10 is placed; and a slide member 70 that is flat and movable in the longitudinal direction relative to the base 60, and has a female screw portion 78a at its inner end in the longitudinal direction that can be threadedly engaged with a male screw portion 31a provided on the outer surface of the rotating shaft 30. The container body 10 includes a slide member 70, and the bottom of the container body 10 is provided with an inclined portion 18 that slopes downward and outward in the longitudinal direction. The slide member 70 has an engagement opening 72 that receives the inclined portion 18 from above. When the container body 10 is placed on the base 60, the inner side of the inclined portion 18 in the longitudinal direction abuts against the inner end of the engagement opening 72, the slide member 70 moves inward in the longitudinal direction, and the female threaded portion 78a threadably engages with the male threaded portion 31a. When the container body 10 is moved upward from the base 60, the outer side of the inclined portion 18 in the longitudinal direction abuts against the outer end of the engagement opening 72, the slide member 70 moves outward in the longitudinal direction, and the threaded engagement between the female threaded portion 78a and the male threaded portion 31a is released. With this configuration, the rotating shaft 30 automatically moves to the bottom dead center when the container body 10 is moved upward from the base 60, eliminating the need to return the rotating shaft 30 that has been extended to the top dead center due to the use of the contents. Then, the contents in the new cartridge can be started to be used simply by placing the new cartridge on the base 60. Therefore, the workability when replacing a used cartridge with a new cartridge can be improved.

[0058] In particular, in this embodiment, the inclined portion 18 extending downward from the container body 10 and the engagement opening 72 that receives it are compactly arranged in the radial center, making it possible to make the engagement portion as small as possible and improve the appearance.

[0059] In addition, in this embodiment, when the container body 10 is moved upward away from the base 60, the slide member 70 moves outward in the longitudinal direction and engages with the base 60. By adopting such a configuration, even when the container body 10 is completely removed from the base 60, the threaded engagement between the female thread portion 78a of the slide member 70 and the male thread portion 31a of the rotating shaft 30 can be maintained in a released state.

[0060] In addition, in this embodiment, at least one of the inner end (opening inner end 72a) or outer end (opening outer end 72b) of the engagement opening 72 is configured to have an inclined surface (inner end inclined surface 72a1 and outer end inclined surface 72b1) that is inclined at approximately the same angle as the inclined portion 18.By adopting such a configuration, the inclined portion 18 and the opening inner end 72a or the opening outer end 72b are in surface contact with each other while driving the slide member 70 in the longitudinal direction, thereby allowing the slide member 70 to move smoothly.

[0061] In addition, in this embodiment, one of the lower part of the middle plate body 20 and the upper part of the rotating shaft 30 is releasably fitted into the other, and the peripheral wall of the middle plate body 20 is releasably fitted into the side wall of the container body 10, and the upward separation force on the middle plate body 20 to disengage the peripheral wall of the middle plate body 20 from the side wall of the container body 10 is configured to be greater than the upward fitting force on the rotating shaft 30 to fit the lower part of the middle plate body 20 with the upper part of the rotating shaft 30.By adopting such a configuration, when the middle plate body 20 holding the contents is advanced upward, the upper part of the rotating shaft 30 is fitted into the lower part of the middle plate body 20, so that the middle plate body 20 holding the contents can be advanced stably regardless of the posture of the advancing container 100.

[0062] Furthermore, in this embodiment, an operating unit 50 that has a flat shape in a plan view and rotates in synchronization with the rotation shaft 30 is provided below the base 60. By adopting such a configuration, the operating unit 50 of the dispensing container 100 does not need to have circumferential irregularities on the operating unit 50 as in conventional dispensing containers, and the flat outer surface makes it easy to rotate the operating unit 50 around the central axis O without the hand slipping. Therefore, there is no need to provide additional irregularities or the like on the outer surface of the dispensing container 100, which makes it possible to expand the range of decoration on the outer surface of the dispensing container 100 and to make it easier to improve the appearance of the dispensing container 100.

[0063] Furthermore, in this embodiment, the container body 10 is further provided with a lid 40 that covers the sides and the top, and the lid 40 is configured to have substantially the same shape as the operating unit 50 in a plan view. By adopting such a configuration, the appearance of the propelling container 100 can be easily arranged.

[0064] In this embodiment, an arm 33 extending in the long axis direction is provided at the bottom of the rotating shaft 30, and the arm 33 engages with a short axis direction operation wall 51b of the operating unit 50, causing the operating unit 50 to rotate in synchronization with the rotating shaft 30. By adopting such a configuration, the rotation of the operating unit 50, which has a flat shape in a plan view, can be efficiently transmitted to the rotating shaft 30, allowing the contents to be dispensed.

[0065] Furthermore, in this embodiment, the container further includes a lid 40 that has a flat shape in a plan view and covers the container body 10 from the sides and above, and is configured so that when the lid 40 is attached, the lid 40 covers at least a portion of the outer peripheral surfaces of both the base 60 and the operating unit 50 from the radially outer side. By adopting this configuration, when the lid 40 is attached, the operating unit 50 cannot be rotated around the central axis O relative to the base 60. Therefore, when the lid 40 is attached, it is possible to prevent the inner tray 20 and contents from being unintentionally advanced by the user.

[0066] Next, a second embodiment of the present disclosure will be described in detail with reference to the drawings. Note that in the second embodiment, the definitions of the up-down direction, front-rear direction, left-right direction, radially outward direction, radially inward direction, and circumferential direction of the propelling container 200 are the same as in the first embodiment, and therefore will not be described here.

[0067] FIG. 8 illustrates a dispensing container 200 according to a second embodiment of the present disclosure. The dispensing container 200 according to this embodiment includes a cylindrical container body 10 with a bottom and an opening 13b at its upper end; a central tray 20 disposed within the container body 10 and supported for vertical movement relative to the container body 10; a rotating shaft 30 extending vertically, supporting the central tray 20 at its upper end and capable of driving the central tray 20 vertically; a lid 40 closing the opening 13b at the upper end of the container body 10; a base 60 on which the container body 10 is placed; a flat-shaped sliding member 70 movable in the longitudinal direction relative to the base 60; and an operating unit 50 disposed below the base 60 and rotating in synchronization with the rotating shaft 30. The dispensing container 200 according to this embodiment is similar in use to the first embodiment, allowing a user to dispense only the required amount of content. In addition, in this embodiment, the container body 10 has a flattened shape that is approximately elliptical in plan view, as shown in FIG. 10 .

[0068] As shown in Figures 8 and 9, the container body 10 has an opening 13b at its upper end, a major axis direction side wall 11a, and a minor axis direction side wall 11b, each having a flat shape that is generally elliptical in plan view, a bottom wall 13 closing the lower ends of the side walls, a support wall 15 hanging down from the outer edge of the bottom wall 13, and an inclined portion 18 that slopes downward from the bottom wall 13 toward the radially outward (major axis direction). The major axis direction side wall 11a here refers to the side wall of the container body 10 that constitutes the major axis direction (long side direction) end (left-right direction in Figure 8, perpendicular to the paper surface of Figure 9, X-axis direction) of the generally elliptical shape in plan view, and the minor axis direction side wall 11b refers to the side wall that constitutes the minor axis direction (short side direction) end (perpendicular to the paper surface of Figure 8, left-right direction in Figure 9, Y-axis direction) of the generally elliptical shape. The following terms will be interpreted similarly.

[0069] 8, when the container body 10 is set on the base 60, the support wall 15 is engaged with the base longitudinal side wall 61a of the base 60 through an undercut to fix the container body 10 to the base 60. Furthermore, by fixing the support wall 15 to the base longitudinal side wall 61a of the base 60, circumferential rotation of the container body 10 relative to the base 60 is restricted.

[0070] As shown in Fig. 8, the inclined portion 18 includes a connecting wall 18a hanging down from the bottom wall 13, inclined portion side walls 18b provided at both ends of the connecting wall 18a in the Y-axis direction (the direction perpendicular to the plane of Fig. 8), and an inclined portion bottom wall 18c provided at the lower part of the inclined portion side walls 18b. A first inclined surface 18f1 that slopes downward and outward in the longitudinal direction is provided at the lower radially inner part of the inclined portion side walls 18b. Furthermore, a second inclined surface 18f2 that slopes downward and outward in the longitudinal direction is provided at the upper outer part of the inclined portion bottom wall 18c in the longitudinal direction.

[0071] As described below, when the undercut engagement between the container body 10 and the base 60 is released and the container body 10 is moved upwardly away from the base 60, the second inclined surface 18f2 on the longitudinal outer side of the inclined portion 18 abuts against the opening outer end 72b of the engagement opening 72 of the slide member 70, and the slide member 70 moves outward in the longitudinal direction. This releases the threaded engagement between the female thread portion 78a of the slide member 70 and the male thread portion 31a of the rotation shaft 30. In this embodiment, when the inclined portion 18 abuts against the opening outer end 72b of the engagement opening 72, the second inclined surface 18f2 provided on the inclined portion bottom wall 18c abuts against the outer end inclined surface 72b1 provided on the opening outer end 72b and substantially parallel to the second inclined surface 18f2. With this configuration, the inclined portion 18 and the opening outer end 72b are in surface contact with each other while driving the slide member 70 outward in the longitudinal direction, thereby enabling smooth movement of the slide member 70. The container body 10 may be made of various synthetic resins or metal materials such as aluminum.

[0072] The middle dish body 20 comprises a dish bottom wall 23 that supports, for example, a rod-shaped content (not shown), a major axis peripheral wall 21a and a minor axis peripheral wall 21b that stand upward from the outer periphery of the dish bottom wall 23, a bottom tubular portion 25 that hangs down from the radially inner side of the dish bottom wall 23, and a central convex wall 23b that has an upwardly convex shape at the radial center of the dish bottom wall 23. In addition, the radially inner surfaces of the major axis peripheral wall 21a and the minor axis peripheral wall 21b are provided with vertical holding ribs 27 that are provided at multiple locations in the circumferential direction and extend in the up and down direction to hold the content, and horizontal holding ribs 29 that extend horizontally to hold the content.

[0073] The inner plate 20 has a flat, generally rectangular shape in plan view and supports a rod-shaped content (not shown) from below, which also has a flat shape in plan view. As described below, the inner plate 20 can move up and down within the container body 10 in conjunction with the vertical movement of the rotating shaft 30. That is, when the rotating shaft 30 is raised by rotating the operating unit 50, the fitting protrusions 35a protruding radially outward from the shaft top 35 of the rotating shaft 30 engage with the fitting claws 25a on the inner surface of the bottom tube 25, driving the inner plate 20 to move upward. The inner plate 20 can also be moved downward by rotating the operating unit 50 in the reverse direction.

[0074] As shown in Figures 8, 9, etc., the intermediate plate body 20 has a major axis peripheral wall 21a and a minor axis peripheral wall 21b corresponding to the flat shape of the major axis side wall 11a and minor axis side wall 11b of the container body 10 in a planar view, and is unable to rotate around the central axis O relative to the container body 10.

[0075] 8, the inner plate 20 has an engagement wall 26 hanging down from the plate bottom wall 23, and is locked by undercut engagement with the connecting wall 18a of the container body 10 at the lowest point of its movable range (in this state, the leg portion 23h of the inner plate 20 abuts the upper surface of the bottom wall 13 of the container body 10). When the user rotates the operating unit 50 around the central axis O and the inner plate 20 is pressed upward by the rotating shaft 30, the fitting protrusion 35a of the rotating shaft 30 fits into the fitting claw 25a on the inner surface of the bottom tube portion 25 of the inner plate 20, so the inner plate 20 moves upward together with the rotating shaft 30.

[0076] In this embodiment, when the container body 10 with the inner plate 20 attached thereto is placed on the base 60 with the rotating shaft 30 at its lowest point, unlike the first embodiment, the engaging claws 25a of the inner plate 20 engage with the engaging protrusions 35a of the rotating shaft 30 in an undercut manner (see FIG. 8 ). This configuration eliminates the need to rotate the rotating shaft 30 extra after the container body 10 is attached to the base 60 to engage the inner plate 20 with the rotating shaft 30 and begin raising the inner plate 20, as in the first embodiment. This reduces the amount of rotation of the rotating shaft 30 required to raise the inner plate 20. This allows for a more compact design with a reduced height for the propelling container 200. Furthermore, because the inner plate 20 can be engaged with the rotating shaft 30 even during distribution, the propelling container 200 is more resistant to drops.

[0077] In this embodiment, the vertical separation force required to disengage the support wall 15 of the container body 10 and the base longitudinal side wall 61a of the base 60 is configured to be greater than the vertical separation force required to disengage the undercut engagement between the engagement wall 26 of the inner plate 20 and the connecting wall 18a of the container body 10. Therefore, when the rotation shaft 30 is rotated about the central axis O by rotating the operating unit 50 and moved upward, the undercut engagement between the engagement wall 26 of the inner plate 20 and the connecting wall 18a of the container body 10 can be disengaged without disengaging the engagement between the support wall 15 of the container body 10 and the base longitudinal side wall 61a of the base 60. This operation allows the inner plate 20 to move vertically relative to the container body 10.

[0078] In this embodiment, the vertical removal force required to disengage the engagement wall 26 of the inner plate 20 from the connecting wall 18a of the container body 10 and remove the inner plate 20 from the container body 10 after the inner plate 20 has been set inside the container body 10 is set to be greater than the vertical fitting force (engagement force) that must be applied to the inner plate 20 to undercut-engage the fitting claws 25a of the inner plate 20 with the fitting protrusions 35a of the rotating shaft 30. With this configuration, when the container body 10 with the inner plate 20 attached thereto is placed on the base 60 with the rotating shaft 30 positioned at its lowest point, the fitting claws 25a of the inner plate 20 can undercut-engage with the fitting protrusions 35a of the rotating shaft 30 without the engagement between the inner plate 20 and the container body 10 being released.

[0079] Furthermore, in this embodiment, the vertical separation force required to release the undercut engagement between the fitting claws 25a of the inner plate 20 and the fitting protrusions 35a of the rotating shaft 30 is set to be greater than the vertical engagement force required to set (engage) the inner plate 20 inside the container body 10. This configuration prevents the undercut engagement between the inner plate 20 and the rotating shaft 30 from being released when the rotating shaft 30 is rotated to the lowest point after using the contents.

[0080] After the undercut engagement between the engagement wall 26 of the inner plate 20 and the connecting wall 18a of the container body 10 is released by rotating the operating part 50, further rotation of the operating part 50 causes the rotating shaft 30 to further press the inner plate 20 upward, with the shaft top 35 of the rotating shaft 30 still engaged with the bottom cylindrical part 25 of the inner plate 20. At this time, the leg part 23h of the inner plate 20 also moves upward away from the bottom wall 13 of the container body 10. This causes the inner plate 20 to be extended upward.

[0081] As described above, when the engagement (undercut engagement) between the engagement wall 26 of the inner plate 20 and the connecting wall 18a of the container body 10 is released, the inner plate 20 is extended further upward. The material of the inner plate 20 can be various synthetic resins, as well as metal materials such as aluminum.

[0082] As for the materials constituting the members other than the container body 10 and the inner plate body 20, it is desirable to use various synthetic resin materials, but the materials are not limited to these.

[0083] 8 and 9, the rotating shaft 30 includes a rotating cylinder portion 31 extending vertically along the central axis O, and a flange portion 33b extending from the lower portion of the rotating cylinder portion 31 toward the radially outer side of the operating unit 50. The outer peripheral surface of the rotating cylinder portion 31 is provided with a male thread portion 31a that can be threadedly engaged with a female thread portion 78a provided on the inner peripheral surface of the slide member 70. A shaft apex portion 35 at the upper end of the rotating cylinder portion 31 fits into the bottom cylinder portion 25 of the central plate body 20 to move the central plate body 20 upward.

[0084] As shown in Figures 8 and 9, the flanges 33b extending in both the long axis direction and the short axis direction are positioned so as to contact the top of the bottom recess 51c2 recessed upward in the bottom wall 51c of the operating unit when the rotating shaft 30 is at bottom dead center. This configuration stabilizes the orientation of the rotating shaft 30 by allowing the lower surface of the flanges 33b of the rotating shaft 30 to contact the upper surface of the bottom recess 51c2. Therefore, when a user attaches the inner plate 20 by engaging the mating tabs 25a of the bottom tube portion 25 of the inner plate 20 with the mating protrusions 35a of the rotating shaft 30, the upper end of the rotating shaft 30 can be positioned approximately in the center in both the long axis direction and the short axis direction. This allows the inner plate 20 to be easily and stably attached to the rotating shaft 30.

[0085] As shown in FIGS. 8 and 10 , a transmission shaft 52 that transmits the rotational operation of the operating unit 50 to the rotating shaft 30 is disposed inside the rotating shaft 30. The transmission shaft 52 has a cylindrical shaft body 52a erected on the upper surface of a bottom recess 51c2 of the operating unit bottom wall 51c, and I-cut portions 52b, which are parallel flat plate portions, are provided at two circumferential locations on the shaft body 52a. The I-cut portions 52b engage with engagement protrusions 31b that are provided on the inner surface of the rotating cylindrical portion 31 of the rotating shaft 30, protrude radially inward, and extend vertically, thereby preventing the rotating shaft 30 and the transmission shaft 52 from rotating relatively around the central axis O. With this configuration, when the operating unit body 51 (operating unit 50) rotates around the central axis O by a user's operation, the operating unit bottom wall 51c, which is fitted with the operating unit body 51 so as not to rotate relatively, also rotates, and the transmission shaft 52, which is integrally formed with the operating unit bottom wall 51c, also rotates around the central axis O. Therefore, the rotation of the operating portion 50 is transmitted to the rotary shaft 30 via the transmission shaft 52, and the rotary shaft 30 also rotates around the central axis O.

[0086] Alternatively, the rotational force may be transmitted from the bottom wall 51c of the operation portion to the flange portion 33b at the lowest point of the rotation shaft 30 by friction, engagement, or the like.

[0087] The operation unit 50 is attached to the lower part of the base 60 (described later) in a state in which it can rotate relatively around a central axis O. The operation unit 50 includes a cylindrical operation unit main body 51, an operation unit bottom wall 51c that closes the lower end of the operation unit main body 51, and an operation unit cover 55 that closes the upper opening of the operation unit main body 51. In this embodiment, unlike the first embodiment, the operation unit bottom wall 51c is a separate part from the operation unit main body 51. The operation unit bottom wall 51c has a bottom peripheral edge 51c1, a bottom recess 51c2 that is recessed upward radially inward of the bottom peripheral edge 51c1, and a bottom side wall 51c3 that stands on the outer edge of the bottom peripheral edge 51c1 and is fitted and fixed to the inner surface of the lower end of the operation unit main body 51. In this embodiment, the operation unit cover 55 is integrally formed with the operation unit main body 51. The operating unit main body 51 has a flat, generally rectangular shape having a major axis (long side) direction and a minor axis (short side) direction in a plan view (see FIG. 10 ), and has generally the same shape as the lid body 40 described below (in FIGS. 8 and 9 , the outer surface of the lid body 40 and the outer surface of the operating unit main body 51 are generally flush with each other). With this configuration, unlike conventional dispensing containers, the operating unit 50 does not need to be provided with circumferential irregularities in the operating unit 50, and the operating unit 50 has a flat outer peripheral surface, making it easy to rotate the operating unit 50 in the circumferential direction about the central axis O without the hand slipping. Therefore, since there is no need to provide irregularities in the outer surface of the dispensing container 200, it is possible to expand the area of ​​decoration on the outer surface of the dispensing container 200 and to easily improve the appearance of the dispensing container 200.

[0088] The operation unit main body 51 includes a long-axis operation wall 51a and a short-axis operation wall 51b, which are operation walls (side walls) having a flat shape in a plan view. An operation unit bottom wall 51c that closes the lower ends of the operation walls is fixed by fitting to the inner surfaces of the lower ends of the long-axis operation wall 51a and the short-axis operation wall 51b.

[0089] An operation unit cover 55 is provided above the operation unit body 51 to cover an upper opening of the operation unit body 51. The operation unit cover 55 includes a cover side wall 55a that has a flat shape in a plan view and is continuous with the operation walls (long-axis direction operation wall 51a and short-axis direction operation wall 51b) of the operation unit body 51, a cover top wall 55b that closes the upper end of the cover side wall 55a, and a cover inner cylinder 55e that hangs down from the radially inner end of the cover top wall 55b.

[0090] 8, the cover inner cylinder 55e engages with an engaging claw portion 67a of a sliding inner wall 67 that hangs down from the radially inner end of a seat base 68 of the seat 60, which will be described later, and is attached so as to be slidable in the circumferential direction relative to the outer circumferential surface of the sliding inner wall 67. With this configuration, the operating unit 50 is supported so as to be rotatable relative to the seat 60 around the central axis O.

[0091] The base 60 has a flattened shape that is approximately rectangular in plan view, and is equipped with side walls (base long axis side wall 61a, base short axis inner wall 69a, and base short axis outer wall 69b), a base base 68 that is connected to the lower end of the side wall (base long axis side wall 61a) and is positioned directly above the cover top wall 55b of the operating unit cover 55, and a sliding inner wall 67 that hangs down from the radially inner end of the base base 68 of the base 60.

[0092] A support wall 15 hanging down from the bottom wall 13 of the container body 10 is fixed by undercut engagement to the radially outer side of the pedestal longitudinal side wall 61a of the pedestal 60. In addition, a slide member 70, which will be described later, is placed on the pedestal base 68.

[0093] In this embodiment, as shown in FIG. 8 , the base protrusion 66 protruding downward from the base base 68 of the base 60 fits into the cover recess 56 recessed downward in the cover top wall 55b of the operating unit 50, thereby engaging the base. With this configuration, the operating unit 50 and the base 60 are engaged at a predetermined relative rotational position, allowing the user to easily recognize that the operating unit 50 and the base 60 are in the rotational position where the longitudinal axes of the operating unit 50 and the base 60 are aligned. Furthermore, the operating unit 50 and the base 60 can be easily positioned in the rotational position where the longitudinal axes of the operating unit 50 and the base 60 are aligned. The engagement between the cover recess 56 and the base protrusion 66 is preferably strong enough that the user can easily release the engagement by holding the container body 10 with one hand while rotating the operating unit 50 with the other hand.

[0094] As shown in FIG. 8 and other figures, the sliding member 70 includes a sliding top wall 71, a sliding outer wall 73 that hangs down from the radially (longitudinal) outer end of the sliding top wall 71, a female thread portion 78a formed on the radially (longitudinal) inner surface of a sliding inner wall 78 provided at the radially inner end of the sliding top wall 71, and minor axis direction side walls 77 (see FIG. 9) that hang down on both sides of the minor axis direction of the sliding top wall 71. The sliding top wall 71 also includes an engagement opening 72 that receives the inclined portion 18 of the container body 10. The engagement opening 72 includes an opening inner end 72a that hangs down from the radially (longitudinal) inner end and an opening outer end 72b that is integrally formed with the sliding outer wall 73 at the radially (longitudinal) outer end. The radial (longitudinal) width of the engagement opening 72 is configured to be narrower than the major axis width of the inclined portion 18. This configuration allows the container body 10 to be separated from the base 60 and the slide member 70, and also allows the slide member 70 to move smoothly when placed on the base 60 and the slide member 70.

[0095] 8, an inner end inclined surface 72a1 is formed at the upper part of the opening inner end 72a, and the inner end inclined surface 72a1 is arranged substantially parallel to the first inclined surface 18f1 of the inclined portion 18. Similarly, an outer end inclined surface 72b1 is formed at the lower part of the opening outer end 72b, and the outer end inclined surface 72b1 is arranged substantially parallel to the second inclined surface 18f2 of the inclined portion 18.

[0096] With the above configuration, when the undercut engagement between the container body 10 and the base 60 is released and the container body 10 is moved upward away from the base 60, the second inclined surface 18f2 on the inclined-portion bottom wall 18c of the inclined portion 18 abuts against the outer-end inclined surface 72b1 of the opening outer end 72b, and the slide member 70 moves outward in the longitudinal direction relative to the container body 10. This releases the threaded engagement between the female threaded portion 78a of the slide member 70 and the male threaded portion 31a of the rotation shaft 30. In this embodiment, the second inclined surface 18f2 and the outer-end inclined surface 72b1, which are provided substantially parallel to each other, abut against each other, driving the slide member 70 outward in the longitudinal direction while the inclined portion 18 and the opening outer end 72b are in surface contact. This allows the slide member 70 to move smoothly outward in the longitudinal direction.

[0097] In this embodiment as well, when the container body 10 is lifted a predetermined distance upward from the state in which it is placed on the base 60 and the slide member 70, the slide member 70 moves radially (in the longitudinal direction) outward by a required distance (a distance longer than (outer diameter - minor diameter) / 2 of the male thread portion 31a). With this configuration, when the slide member 70 moves radially (in the longitudinal direction) outward by the required distance, the female thread portion 78a is reliably released from the male thread portion 31a.

[0098] In this embodiment, the operation of moving the container body 10 upward from the base 60 causes the slide member 70 to move radially (longitudinally) outward. At that time, the engagement claws 77b provided on the minor axis sidewall 77 of the slide member 70 maintain undercut engagement with the engagement protrusions 61b2 on the base 60. With this configuration, even when the container body 10 is completely removed from the base 60, the slide member 70 remains locked in its radially (longitudinal) position, so that the threaded engagement between the female thread portion 78a of the slide member 70 and the male thread portion 31a of the rotation shaft 30 can be maintained in a released state. In this specification and the claims, the term "lock" broadly means that one element acts on another element to stop movement.

[0099] The manner in which the slide member 70 is locked radially outward when the container body 10 is moved upwardly away from the base 60 is not limited to the above. For example, a rib extending in the vertical direction may be provided on the side surface of the slide member 70 in the minor axis direction, and this rib may come into surface contact with a rib provided on the inner surface of the side wall of the base 60, so that the slide member 70 is locked to the base 60 by friction.

[0100] 13, when the container body 10 with the inner plate 20 housed therein is placed on the base 60 and the container body 10 and base 60 are undercut-engaged, the first inclined surface 18f1 of the inclined portion 18 abuts against the inner end inclined surface 72a1 of the opening inner end 72a. This causes the first inclined surface 18f1 and the inner end inclined surface 72a1, which are provided substantially parallel to each other, to abut against each other, thereby pressing the slide member 70 with the surface, allowing smooth movement inward in the radial direction (longitudinal direction). When the slide member 70 moves inward in the radial direction (longitudinal direction), the female threaded portion 78a of the slide member 70 again threadably engages with the male threaded portion 31a of the rotation shaft 30. With this configuration, when the container body 10 is placed on the base 60, the male threaded portion 31a of the rotating shaft 30 and the female threaded portion 78a of the sliding member 70 are threadedly engaged, so that the rotating shaft 30 can move upward relative to the sliding member 70 as it rotates around its own central axis O.

[0101] As shown in Fig. 9, the minor axis side wall 77 is provided with an engagement claw 77b that protrudes outward in the minor axis direction. As shown in Fig. 9, the engagement claw 77b engages with an engagement protrusion 61b2 of the base 60, restricting movement in directions other than the radial direction. When attaching the slide member 70 to the base 60, the slide member 70 can be attached by placing the slide member 70 inside the base 60 from above in Fig. 8 and then undercut-engaging the above-mentioned engagement claw 77b with the engagement protrusion 61b2.

[0102] As shown in FIG. 8, the lid 40 has a cylindrical shape with a top and closes the opening 13b at the upper end of the container body 10. The lid 40 has a flat shape that is generally rectangular in plan view, and includes lid side walls (longitudinal lid side walls 41 and minor axial lid side walls 42) and a top wall 43 that is continuous with the upper ends of the lid side walls. In plan view, the lid 40 has generally the same shape as the operating unit 50 (see FIG. 10). (In FIGS. 8 and 9, the outer surfaces of the lid 40 and the operating unit main body 51 are generally flush with each other.) In addition, the lower inner surfaces of the longitudinal axial lid side walls 41 and minor axial lid side walls 42 of the lid 40 have generally the same shape as the upper outer surface of the cover side wall 55a of the operating unit cover 55, as shown in FIGS. 8 and 9. The lid 40 is removably fixed by the inner circumferential surface of the lid side wall abutting against the outer circumferential surface of the cover side wall 55a of the operation unit cover 55.

[0103] In this embodiment, as shown in FIG. 8 and other figures, when the lid 40 is attached, the lower portions of the major axis lid sidewall 41 and the minor axis lid sidewall 42 of the lid 40 cover the outer peripheral surface of the base 60 and the outer peripheral surface of the upper portion of the operating unit 50. This prevents the operating unit 50 from rotating around the central axis O relative to the container body 10. This is because the container body 10 and the operating unit 50, both of which have flat shapes, are covered from the radial outside by the lid 40, which also has a flat shape, preventing relative rotation in the circumferential direction. Therefore, when the lid 40 is attached, it is possible to prevent the inner tray 20 and contents from being unintentionally advanced by the user.

[0104] With the above-described configuration, when the lid body 40 is attached, it is necessary to align the long axis direction of the container body 10 with the long axis direction of the operation part 50 in advance.

[0105] When using the dispensing container 200 having such a configuration, the user first grasps the lid body side wall (normally, the short-axis lid side wall 42) of the lid body 40 from the state shown in Figure 8 and pulls it upward, opening the opening 13b on the upper end side of the container body 10 and exposing the contents. Next, the user grasps the outer peripheral surface of the container body 10 (normally, the outer peripheral surface of the short-axis side wall 11b) with one hand and grasps the operating wall of the operating unit body 51 (normally, the short-axis operating wall 51b) with the other hand, and rotates it around the central axis O.

[0106] By rotating the operation unit main body 51 about the central axis O relative to the container body 10, the operation unit bottom wall 51c that fits into the operation unit main body 51 also rotates in sync. A transmission shaft 52 is integrally formed in a bottom recess 51c2 of the operation unit bottom wall 51c, and the transmission shaft 52 also rotates as the operation unit bottom wall 51c rotates. Therefore, the engagement between the I-cut portion 52b of the transmission shaft 52 and the engaging protrusion 31b of the rotation shaft 30 shown in FIG. 10 causes the rotation shaft 30 to also rotate. The rotation shaft 30 also rotates relative to the female thread portion 78a of the slide member 70 fixed to the base 60, and the male thread portion 31a engages with the female thread portion 78a, causing the rotation shaft 30 to move upward relative to the base 60 and the slide member 70.

[0107] When the rotating shaft 30 moves upward relative to the base 60 and the sliding member 70, the shaft top 35 of the rotating shaft 30 fits inside the bottom tube portion 25 of the inner plate 20, pushing the inner plate 20 upward. This pushing up of the inner plate 20 by the rotating shaft 30 disengages the connecting wall 18a on the container body 10 from the engaging wall 26 on the inner plate 20, and the inner plate 20 is extended upward to the top dead center (see FIGS. 11 and 12). In this embodiment, the separation force required to disengage the support wall 15 of the container body 10 from the base longitudinal axis side wall 61a of the base 60 is configured to be greater than the separation force required to disengage the undercut engagement between the engaging wall 26 on the inner plate 20 and the connecting wall 18a on the container body 10. Therefore, the undercut engagement between the engaging wall 26 of the inner plate 20 and the connecting wall 18a of the container body 10 can be released without disengaging the support wall 15 of the container body 10 and the base longitudinal axis side wall 61a of the base 60. This operation allows the inner plate 20 to move vertically relative to the container body 10.

[0108] In this embodiment, the shaft apex 35 at the upper end of the rotating shaft 30 fits inside the bottom tube portion 25 of the inner plate 20, and the radial center portion of the upper surface of the shaft apex 35 is recessed, while the central convex wall 23b of the inner plate 20 is formed in a generally flat plate shape. Therefore, the peripheral portion of the upper surface of the shaft apex 35 abuts against the lower surface of the central convex wall 23b. Therefore, the upper surface of the shaft apex 35 and the lower surface of the central convex wall 23b can be in surface contact over the entire peripheral portions, allowing the rotating shaft 30 to advance the inner plate 20 upward in a stable position.

[0109] When the rod-shaped contents fixed to the inner plate 20 are used up, the user separates the container body 10 and the inner plate 20 upward and removes them from the base 60. To separate the container body 10 and the inner plate 20 from the base 60, the user grasps the minor axis direction side wall 11b of the container body 10 while gripping the minor axis direction operating wall 51b of the operating part body 51, and pulls them upward, thereby releasing the undercut engagement between the base engaging claws 61a1 of the base major axis direction side wall 61a and the support wall 15, as well as the undercut engagement between the bottom tube portion 25 and the shaft top portion 35.

[0110] By the above operation, the inclined portion bottom wall 18c of the inclined portion 18 abuts against the opening outer end 72b of the slide member 70, and the slide member 70 moves outward in the longitudinal direction. This releases the threaded engagement between the female thread portion 78a of the slide member 70 and the male thread portion 31a of the rotation shaft 30. In this embodiment, when the inclined portion 18 abuts against the opening outer end 72b of the engagement opening 72, the second inclined surface 18f2 provided on the inclined portion bottom wall 18c abuts against the outer end inclined surface 72b1 provided on the opening outer end 72b and substantially parallel to the second inclined surface 18f2. With this configuration, the inclined portion 18 and the opening outer end 72b are in surface contact with each other while driving the slide member 70 outward in the longitudinal direction, thereby enabling smooth movement of the slide member 70.

[0111] By releasing the thread engagement between the female thread portion 78a and the male thread portion 31a, the rotating shaft 30, which had moved to the top dead center, moves to the bottom dead center. In this manner, in this embodiment, the rotating shaft 30 is automatically moved to the bottom dead center by separating the container body 10 from the base 60. Therefore, there is no need to return the rotating shaft 30, which has been extended to the top dead center due to the use of the contents, to its original position. Then, with the rotating shaft 30 moved to the bottom dead center, the contents of the new cartridge can be started by simply placing a new cartridge (the container body 10 and the inner plate 20 holding the new contents) on the base 60. At this time, the engagement between the container body 10 and the base 60 and the engagement between the inner plate 20 and the rotating shaft 30 are also completed. Therefore, the operability of replacing a used cartridge with a new cartridge can be improved.

[0112] As described above, in this embodiment, when the rotating shaft 30 is positioned at the lowest point of its movable range, the inner plate 20 and the rotating shaft 30 are engaged when the container body 10 is engaged with the base 60 while the inner plate 20 is engaged with the container body 10. By adopting this configuration, after the container body 10 is attached to the base 60, there is no need to rotate the rotating shaft 30 extra to engage the inner plate 20 with the rotating shaft 30 and begin raising the inner plate 20. This reduces the amount of rotation of the rotating shaft 30 required to raise the inner plate 20. This allows for a more compact design with a reduced height for the advancing container 200. Furthermore, because the inner plate 20 can be engaged with the rotating shaft 30 even during distribution, the advancing container 200's resistance to drops is increased.

[0113] In addition, in this embodiment, the middle plate body 20 is releasably engaged with the rotating shaft 30, the middle plate body 20 is releasably engaged with the container body 10, the container body 10 is releasably engaged with the base 60, the vertical separation force required to disengage the container body 10 from the base 60 is greater than the vertical separation force required to disengage the middle plate body 20 from the container body 10, the vertical separation force required to disengage the middle plate body 20 from the container body 10 is greater than the vertical engagement force required to engage the middle plate body 20 with the rotating shaft 30, and the vertical separation force required to disengage the middle plate body 20 from the rotating shaft 30 is greater than the vertical engagement force required to engage the middle plate body 20 with the container body 10. With this configuration, when the operating unit 50 is rotated to rotate the rotating shaft 30 about the central axis O and move it upward, the undercut engagement between the engaging wall 26 of the inner plate 20 and the connecting wall 18a of the container body 10 can be released without disengaging the support wall 15 of the container body 10 and the longitudinal axis side wall 61a of the base 60. This allows the inner plate 20 to be moved vertically relative to the container body 10. Furthermore, when the container body 10 with the inner plate 20 containing contents mounted therein is placed on the base 60 with the rotating shaft 30 positioned at its lowest point, the engaging claws 25a of the inner plate 20 can be undercut-engaged with the engaging protrusions 35a of the rotating shaft 30 without disengaging the inner plate 20 from the container body 10. Furthermore, the undercut engagement between the inner plate 20 and the rotating shaft 30 can be prevented from being released when the rotating shaft 30 is rotated to its lowest point after using the contents.

[0114] Although the present disclosure has been described based on various drawings and examples, it should be noted that those skilled in the art can easily make various modifications and alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included in the scope of the present invention. For example, the functions included in each component can be rearranged so as not to cause logical inconsistencies, and multiple components can be combined into one or divided. It should be understood that these modifications and alterations are also included in the scope of the present invention.

[0115] For example, in the first and second embodiments, the other main components are configured to have a similar flat shape in accordance with the flat shape of the container body 10 in a plan view, but this is not limited to this. For example, the operation unit 50 may be configured not to have a flat shape in a plan view.

[0116] In addition, in the first embodiment, an approximately rectangular shape is adopted as the flat shape of the container body 10 when viewed in a plane, and in the second embodiment, an approximately elliptical shape is adopted as the flat shape of the container body 10 when viewed in a plane, but this is not limited to this form and other flat shapes such as an approximately track shape or an egg shape may also be used.

[0117] In the first embodiment, inclined portion 18 is configured to include connecting wall 18a, inclined portion bottom wall 18c, inclined portion side wall 18b, and lower protrusion 18e2 in addition to inclined portion main wall 18e1. However, this is not limited to this configuration, and a configuration may be adopted in which at least one of the components other than inclined portion main wall 18e1 is not provided. For example, an additional inclined surface that abuts outer end inclined surface 72b1 may be provided on inclined portion main wall 18e1 without providing lower protrusion 18e2. Also, a configuration may be adopted in which inner end inclined surface 72a1 and outer end inclined surface 72b1 are not provided.

[0118] In the second embodiment, the inclined portion 18 is configured to include the connecting wall 18a and the inclined portion bottom wall 18c in addition to the inclined portion side wall 18b. However, the present invention is not limited to this configuration, and the inclined portion 18 may be configured without including at least one wall other than the inclined portion side wall 18b. For example, the inclined portion side wall 18b may be configured without including the inclined portion bottom wall 18c, and a second inclined surface may be provided on the inclined portion side wall 18b. Furthermore, the inner end inclined surface 72a1 and the outer end inclined surface 72b1 may also be configured without being provided.

[0119] In the second embodiment, the transmission shaft 52 having the I-cut portion 52b is engaged with the engaging protrusion 31b provided on the inner surface of the rotation shaft 30, and the rotation shaft 30 is rotated by rotating the operation unit 50 fixed to the transmission shaft 52. However, the present invention is not limited to this. For example, in FIG. 8, the cover inner cylinder 55e of the operation unit cover 55 may be extended to the height position of the flange portion 33b, and the flange portions 33b, which are arranged intermittently in the circumferential direction, may fit into cutout portions provided at specific positions in the circumferential direction of the cover inner cylinder 55e, thereby transmitting the rotational force from the operation unit 50 to the rotation shaft 30. [Industrial Applicability]
