And the latching protrusion 13a provided in the outer peripheral surface of the fitting cylinder 13 carries out an undercut engagement with the cyclic | annular protrusion 41a formed in the inner peripheral surface of the cover body side wall 41 of the cover body 40 mentioned later, A lid | cover The body 40 can be detachably fixed to the container body 10. In addition, as a material of the container main body 10, metal materials, such as aluminum other than various synthetic resins, can be used.

  The middle dish body 20 includes a dish-shaped portion 21 that supports a rod-shaped content (not shown) from below, an inner cylindrical wall 23 that extends in the vertical direction and extends to the inner peripheral end of the dish-shaped portion 21, and an outer peripheral end of the dish-shaped portion 21 And an outer cylindrical wall 27 extending in the vertical direction.

  The dish-like portion 21 is a plate-like portion that extends radially outward from the inner cylindrical wall 23 that penetrates the rotation shaft 31 of the rotating body 30 and substantially in the horizontal direction, and supports the rod-shaped contents from below. On the inner peripheral surface of the inner cylindrical wall 23, as shown in FIG. 2, a female screw portion 23 a that can be screw-engaged with a male screw portion 31 a (see FIG. 3 etc.) formed on the outer peripheral surface of the rotating shaft 31 is provided. Yes. That is, the male screw portion 31a and the female screw portion 23a constitute a pair of screw engaging portions. As described above, the middle dish body 20 is configured to be relatively unrotatable with respect to the container body 10, so that the middle dish body can be obtained by rotating the rotation shaft 31 around the central axis C with respect to the container body 10. The middle dish body 20 can be moved in the vertical direction via the screw engaging portion.

  The outer cylindrical wall 27 is a cylindrical portion that extends in the vertical direction and continues to the outer peripheral end of the dish-shaped portion 21. As shown in FIG. 3, the outer cylinder wall 27 is provided with a guide groove 27b (concave portion) extending in the vertical direction along the central axis C on the outer peripheral surface, and the inner periphery of the container body 10 is provided in the guide groove 27b. By fitting the protrusions 11 a (convex portions) formed on the surface, the inner dish body 20 is not rotatable around the central axis C with respect to the container body 10.

  As shown in FIG. 2 and FIG. 3, ribs 23 d that protrude radially inward are formed in two portions of the inner cylindrical wall 23 below the dish-like portion 21 in the circumferential direction. The rib is a member provided in a direction perpendicular to the planes for reinforcing the flat plate portion and the thin wall portion, and the rib 23d of the present embodiment is formed integrally with the inner cylindrical wall 23. The rib 23d is formed on the inner peripheral surface of the inner cylindrical wall 23, is configured with a smooth R surface in plan view, and has a generally uniform shape in the vertical direction.

  As shown in FIG. 3, the inner cylinder wall 23 has a wall thickness thinner than other circumferential positions at a predetermined circumferential position (left and right direction in FIG. 3) including the circumferential position where the rib 23d is formed. The thin-walled portion 23c is formed. With this configuration, as will be described later, when the rotating shaft 31 is rotated 90 degrees around the central axis C, the rib 23d and the male screw portion 31a in which the notch 31b is not formed in the rotating shaft 31 come into contact with each other (see FIG. 4), the thin-walled portion 23c is deformed radially outward to receive the male threaded portion 31a, and the rib 23d presses the male threaded portion 31a radially inward, whereby the rotating shaft 31 and the inner cylindrical wall 23 are slid. Dynamic resistance can be increased.

  As shown in FIG. 2, the rotating body 30 includes a rotating shaft 31 that penetrates the radially inner side of the inner cylindrical wall 23 of the inner tray body 20, a bottom wall 33 that extends radially outward from a lower end portion 31 c of the rotating shaft 31, and And a grip portion 35 that is continuous with the outer peripheral end of the bottom wall 33.

  As shown in FIG. 2, the rotating shaft 31 extends in the vertical direction along the central axis C of the feeding container 100 and penetrates the radially inner side of the inner cylindrical wall 23 of the inner tray body 20. As shown in FIG. 3, the rotating shaft 31 has a cross-sectional shape in which a male thread portion 31 a is formed on the outer peripheral surface, and notches 31 b are formed in two opposite positions in the circumferential direction, so-called I-cut. ing. And in this embodiment, the notch 31b of the rotating shaft 31 is formed by the distance between the radial inner ends of the ribs 23d provided at two locations facing each other in the circumferential direction on the inner circumferential surface of the inner cylindrical wall 23. It is comprised so that it may become shorter than the outer diameter in the circumferential direction position which is not. By adopting such a configuration, the user rotates the rotating shaft 31 around the central axis C, and abuts the rib 23d and the male screw portion 31a at the circumferential position where the notch 31b is not formed. As shown in FIG. 4, the thin-walled portion 23c on the inner plate 20 side is deformed radially outward to receive the male screw portion 31a, and the rib 23d presses the male screw portion 31a radially inward, thereby rotating the rotating shaft. The sliding resistance between 31 and the inner cylinder wall 23 increases.

  A disc-shaped bottom wall 33 that extends radially outward and substantially in the horizontal direction is provided at the lower end 31 c of the rotating shaft 31. A cylindrical gripping portion 35 is formed at the outer peripheral end of the bottom wall 33 and is held downward when the user rotates the rotating body 30. The user of the delivery container 100 rotates the gripping portion 35 with respect to the container body 10 by holding the gripping portion 35 with the other hand while gripping the outer peripheral surface of the container body 10 with one hand. The contents supported by the inner dish 20 can be fed upward from the opening 13b by being rotated around C.

  On the outer peripheral surface in the vicinity of the lower end 31c of the rotating shaft 31, an engaging protrusion 31d that slightly protrudes radially outward is formed. When inserting and assembling the rotary shaft 31 into the opening 15b of the container body 10, it is difficult to pull out the rotating body 30 downward by engaging the claw portion 15a on the container body 10 side with the engagement protrusion 31d. Can be held in a stable state.

  The lid body 40 has a top-like cylindrical shape and closes the opening 13 b at the upper end of the container body 10. The lid 40 has a lid side wall 41 and a top wall 43 that is continuous with the upper end of the lid side wall 41. The lid 40 is configured such that the annular protrusion 41a on the inner peripheral surface of the lid side wall 41 is undercut engaged with a locking projection 13a provided on the outer peripheral surface of the fitting cylinder 13 on the container body 10 side. The main body 10 is detachably fixed.

  When using the feeding container 100 having such a configuration, first, the user pulls upward from the state of FIG. 1 while grasping the lid side wall 41 of the lid 40, and opens the opening 13 b on the upper end side of the container body 10. To expose the contents. Next, the user rotates around the central axis C while holding the outer peripheral surface of the container body 10 with one hand and holding the holding portion 35 of the rotating body 30 with the other hand. At this time, the intermediate dish body 20 is supported so as not to rotate with respect to the container body 10 by fitting the protrusions 11 a into the guide grooves 27 b, so that the rotating body 30 rotates with respect to the intermediate dish body 20. It will be. In the present embodiment, both the male screw portion 31a on the rotating body 30 side and the female screw portion 23a on the inner plate body 20 side are configured as double threads, so that the rotating body 30 can be rotated by rotating clockwise in a bottom view. The middle plate 20 can be moved upward by a distance corresponding to two pitches of the double thread per one rotation of the body 30.

  When the rotating body 30 is rotated relative to the container body 10, as shown in FIGS. 2 and 3, there is a state where there is a gap between the rib 23d provided on the intermediate dish body 20 and the rotating shaft 31; As shown in FIGS. 4 and 5, the state in which the rib 23 d is in contact with the male screw portion 31 a of the rotating shaft 31 is alternately switched. When the rib 23d is in contact with the male threaded portion 31a of the rotating shaft 31, the thin-walled portion 23c is deformed radially outward, and the rib 23d presses the male threaded portion 31a radially inward by the elastic force accompanying the deformation. As a result, the sliding resistance between the rotating shaft 31 and the inner cylinder wall 23 increases. However, in the present embodiment, even when the rib 23d is in contact with the male thread portion 31a of the rotation shaft 31, the user can easily rotate the rotating body 30 by gripping the grip portion 35. Only sliding resistance is generated. Therefore, the user can easily rotate the rotating body 30 and feed the contents upward from the opening 13b while feeling some fluctuation of the sliding resistance when rotating the rotating body 30.

  On the other hand, when the user accommodates and carries the feeding container 100 in a bag or the like, an external force may act on the rotating body 30 due to friction between the bag and the feeding container 100 or the like. However, as described above, since the circumferential position (FIGS. 4 and 5) that increases the sliding resistance of the rotating body 30 with respect to the inner tray body 20 is provided, an unintended external force acts on the rotating body 30. However, the rotating body 30 stops at the circumferential position where the sliding resistance increases, and the rotating body 30 does not rotate any further. That is, in the present embodiment, the user can easily move the rotating body 30 against the sliding resistance at the circumferential position (FIGS. 4 and 5) where the sliding resistance of the rotating body 30 with respect to the inner dish 20 increases. While being able to rotate, the sliding resistance of the grade which does not rotate by the friction etc. between a bag and the delivery container 100 generate | occur | produces. Therefore, when the user accommodates and carries the delivery container 100 in a bag or the like, unintended delivery of the contents can be suppressed.

  As described above, in the present embodiment, the cylindrical container body 10 having the opening 13b in the upper portion, the inner cylinder that is disposed in the container body 10 and that is continuous with the dish-shaped portion 21 and the inner peripheral ends of the dish-shaped portion 21. An intermediate dish body 20 having a wall 23, which is movable in the vertical direction with respect to the container body 10 and is supported so as not to rotate, and a rotary shaft 31 extending in the vertical direction and penetrating radially inside the inner cylindrical wall 23. A screw engaging portion (a male screw portion 31a and a female screw portion 23a) is formed on the outer peripheral surface of the rotary shaft 31 and the inner peripheral surface of the inner cylindrical wall 23, and the outer periphery of the rotary shaft 31. The surface is formed with a notch 31b at at least one location in the circumferential direction, and an inner circumferential surface of the inner cylinder wall 23 is formed with a protruding portion 23d that projects radially inward at at least one location in the circumferential direction. Configured. By adopting such a configuration, there is a circumferential position where the sliding resistance of the rotating body 30 with respect to the middle dish body 20 increases when the rotating body 30 rotates with respect to the middle dish body 20. Accordingly, when the user accommodates and carries the feeding container 100 in a bag or the like, even if an external force acts on the rotating body 30 due to friction or the like, the circumferential position where the sliding resistance of the rotating body 30 with respect to the inner tray body 20 increases. Thus, the rotation of the rotating body 30 stops. Thereby, unintended delivery of the contents can be suppressed.

  In the present embodiment, the outer peripheral surface of the rotating shaft 31 is formed with notches 31b at two locations facing each other in the circumferential direction, and the inner peripheral surface of the inner cylindrical wall 23 is formed at two locations facing each other in the circumferential direction. By adopting such a configuration in which the rib 23d protruding radially inward is formed, when the rotating body 30 rotates with respect to the inner dish body 20, the rotating body 30 with respect to the inner dish body 20 There are two circumferential positions where the sliding resistance increases in one rotation. Therefore, the rotation of the rotating body 30 can be more reliably stopped at the two circumferential positions where the sliding resistance of the rotating body 30 with respect to the inner tray body 20 increases. Thereby, unintended delivery of the contents can be reliably suppressed.

  Further, in the present embodiment, the distance between the radially inner ends of the ribs 23d that are formed at two opposite locations in the circumferential direction and project radially inward is the circumferential position where the notch 31b of the rotating shaft 31 is not formed. It was configured to be shorter than the outer diameter. By adopting such a configuration, the rib 23d more reliably generates the sliding resistance of the rotating body 30 with respect to the inner tray body 20 when contacting the male screw portion 31a at the circumferential position where the notch 31b is not formed. be able to. Therefore, the rotation of the rotating body 30 can be more reliably stopped at the circumferential position (see FIGS. 4 and 5) where the sliding resistance of the rotating body 30 with respect to the middle dish body 20 increases. Thereby, unintended delivery of the contents can be reliably suppressed.

  Further, in the present embodiment, the inner cylindrical wall 23 has the thin wall portion 23c whose wall thickness is thinner than other circumferential positions at a predetermined circumferential position including the circumferential position where the protruding portion 23d is formed. Configured to have. By adopting such a configuration, when the projecting portion 23d abuts on the male screw portion 31a at the circumferential position where the notch 31b is not formed, the thin-walled portion 23c is elastically deformed radially outward, thereby rotating the rotating body. 30 can be easily rotated relative to the middle dish 20. Therefore, when the user intentionally rotates the rotating body 30, it can be rotated smoothly.

  Further, in the present embodiment, the middle dish body 20 further includes an outer cylindrical wall 27 that is continuous with the outer peripheral end of the dish-shaped portion 21, and is formed on one of the outer peripheral surface of the outer cylindrical wall 27 and the inner peripheral surface of the container body 10. The protrusion (projection 11a) extending in the central axis C direction is fitted in a recess (guide groove 27b) formed on the other of the outer peripheral surface of the outer cylindrical wall 27 and the inner peripheral surface of the container body 10 and extending in the central axis C direction. By combining, the intermediate dish 20 was configured to be supported so as not to rotate with respect to the container body 10. By adopting such a configuration, it is possible to reliably support the inner dish body 20 so as not to rotate with respect to the container body 10 and to rotate the rotating body 30 relative to the inner dish body 20. The rotation can be converted into the vertical movement of the intermediate dish 20 through the screw engaging portion.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, functions included in each component can be rearranged so as not to be logically contradictory, and a plurality of components can be combined into one or divided. It should be understood that these are included within the scope of the present invention.

  For example, in the present embodiment, the protrusion 11 a is formed on the inner peripheral surface of the container main body 10, and the guide groove 27 b is formed on the outer peripheral surface of the outer cylindrical wall 27 of the intermediate dish body 20, thereby The middle dish body 20 is configured to be non-rotatable, but is not limited to this mode. A guide groove may be formed on the inner peripheral surface of the container body 10, and a protrusion may be formed on the outer peripheral surface of the outer cylindrical wall 27 of the intermediate dish 20. Moreover, you may employ | adopt convex parts and recessed parts other than a protrusion and a guide groove.

  In the present embodiment, the rib 23d extending in the direction of the central axis C is provided as a protruding portion protruding from the inner peripheral surface of the inner cylindrical wall 23. However, the present invention is not limited to this mode. As the protruding portion, a protruding portion or the like may be provided on the inner peripheral surface of the inner cylindrical wall 23. In addition, the protrusions do not necessarily have to be provided at two locations facing each other in the circumferential direction, and may be provided only at one location in the circumferential direction or at three or more locations in the circumferential direction.

  Moreover, in this embodiment, although it comprised so that the notch 31b might be provided in two places which the circumferential direction opposes in the rotating shaft 31, it is not limited to this aspect. The cutout 31b may be provided at only one place in the circumferential direction to form a D-cut, or the cutout 31b may be provided at three or more places in the circumferential direction. Further, the notch 31b is not limited to a plane parallel to the central axis C as shown in FIGS. 3 and 4, and may be formed of a curved surface.

  Moreover, in this embodiment, although it comprised so that the rotating shaft 31 and the inner cylinder wall 23 might provide the male thread part 31a and female thread part 23a which have a structure of a double thread, it is not limited to this aspect. The male screw portion 31a and the female screw portion 23a may be a single thread or a multi-thread other than a double thread.

  Next, a feeding container 200 according to the second embodiment of the present invention will be described with reference to FIGS. The feeding container 200 according to the present embodiment is similar to the configuration of the first embodiment except that the configuration of the inner cylindrical wall 23 is partially different from that of the first embodiment. Here, it demonstrates centering on difference with 1st Embodiment.

  As shown in FIGS. 6 and 7, a rib 23 e that protrudes radially inward is formed in a portion of the inner cylindrical wall 23 below the dish-like portion 21, as shown in FIGS. 6 and 7. The rib 23 e is formed on the inner peripheral surface of the inner cylindrical wall 23 and is configured by a region surrounded by a plane parallel to the central axis C and the inner peripheral surface of the inner cylindrical wall 23. Further, the rib 23e has a generally uniform shape in the vertical direction.

  As shown in FIG. 6, the rotating body 30 includes a rotating shaft 31 that penetrates the radially inner side of the inner cylindrical wall 23 of the inner tray body 20, a bottom wall 33 that extends radially outward from a lower end portion 31 c of the rotating shaft 31, and And a grip portion 35 that is continuous with the outer peripheral end of the bottom wall 33.

  As shown in FIG. 6, the rotation shaft 31 extends in the vertical direction along the central axis C of the feeding container 200, and penetrates the radially inner side of the inner cylindrical wall 23 of the intermediate tray body 20. As shown in FIG. 7, the rotating shaft 31 has a cross-sectional shape in which a male thread portion 31 a is formed on the outer peripheral surface, and notches 31 b are formed in two opposite positions in the circumferential direction, so-called I-cut. ing. In the present embodiment, the maximum distance between the radially inner end of the rib 23e provided on the inner peripheral surface of the inner cylindrical wall 23 and the inner peripheral surface of the inner cylindrical wall 23 in plan view is the cutting distance of the rotary shaft 31. It is comprised so that it may become shorter than the outer diameter in the circumferential direction position in which the notch 31b is not formed. By adopting such a configuration, the user rotates the rotating shaft 31 around the central axis C, and abuts the rib 23e and the male screw portion 31a at the circumferential position where the notch 31b is not formed. As shown in FIG. 8, the rotating shaft 31 is pressed by the rib 23e in the direction opposite to the rib 23e. Accordingly, the rotation shaft 31 is eccentric to the left in FIG. 8 and FIG. 9 with respect to the central axis C, and is pressed against the inner peripheral surface of the inner cylindrical wall 23 facing the rib 23e. Therefore, the sliding resistance between the rotating shaft 31 and the inner cylinder wall 23 when the rotating body 30 is rotated around the central axis C increases.

  When using the feeding container 200 having such a configuration, the user grips the outer peripheral surface of the container body 10 with one hand after pulling out the lid 40 from the container body 10 as in the first embodiment. While holding the grip portion 35 of the rotating body 30 with the other hand, it is rotated around the central axis C. At this time, the intermediate dish body 20 is supported so as not to rotate with respect to the container body 10 by fitting the protrusions 11 a into the guide grooves 27 b, so that the rotating body 30 rotates with respect to the intermediate dish body 20. It will be. In this embodiment, since both the male thread part 31a on the rotating body 30 side and the female thread part 23a on the intermediate dish 20 side are configured as double threads, the rotating body 30 can be rotated by rotating it clockwise in a bottom view. The middle plate 20 can be moved upward by a distance corresponding to two pitches of the double thread per one rotation of the body 30.

  When the rotary body 30 is rotated relative to the container body 10, as shown in FIGS. 6 and 7, there is a state where there is a gap between the rib 23e provided on the intermediate dish body 20 and the rotary shaft 31, As shown in FIGS. 8 and 9, the state in which the rib 23 e is in contact with the male screw portion 31 a of the rotating shaft 31 is alternately switched. When the rib 23e is in contact with the male thread 31a of the rotating shaft 31, the rotating shaft 31 is pressed in the opposite direction to the rib 23e by the rib 23e. 8 and 9, it is decentered in the left direction and is pressed against the inner peripheral surface of the inner cylindrical wall 23 facing the rib 23e. Therefore, the sliding resistance between the rotating shaft 31 and the inner cylinder wall 23 when the rotating body 30 is rotated around the central axis C increases. However, in the present embodiment, even when the rib 23e is in contact with the male screw portion 31a of the rotating shaft 31, the user can easily rotate the rotating body 30 by gripping the grip portion 35. Only sliding resistance is generated. Therefore, the user can easily rotate the rotating body 30 and feed the contents upward from the opening 13b while feeling some fluctuation of the sliding resistance when rotating the rotating body 30.

  On the other hand, when the user accommodates and carries the feeding container 200 in a bag or the like, an external force may act on the rotating body 30 due to friction between the bag and the feeding container 200. However, as described above, since the circumferential position (FIGS. 8 and 9) that increases the sliding resistance of the rotating body 30 with respect to the inner tray body 20 is provided, an unintended external force acts on the rotating body 30. However, the rotating body 30 stops at the circumferential position where the sliding resistance increases, and the rotating body 30 does not rotate any further. That is, in the present embodiment, the user can easily move the rotating body 30 against the sliding resistance at the circumferential position (FIGS. 8 and 9) where the sliding resistance of the rotating body 30 with respect to the inner dish 20 increases. While being able to rotate, the sliding resistance of the grade which does not rotate by the friction etc. between a bag and the delivery container 200 generate | occur | produces. Therefore, when the user accommodates and carries the delivery container 200 in a bag or the like, unintended delivery of the contents can be suppressed.

  As described above, in the present embodiment, the outer peripheral surface of the rotating shaft 31 is formed with the notches 31b at two locations facing each other in the circumferential direction, and the inner peripheral surface of the inner cylindrical wall 23 has 1 in the circumferential direction. The rib 23e is formed so as to protrude radially inward at the location. By adopting such a configuration, there are two circumferential positions in one rotation where the sliding resistance of the rotating body 30 with respect to the middle dish body 20 increases when the rotating body 30 rotates with respect to the middle dish body 20. To do. Therefore, the rotation of the rotating body 30 can be more reliably stopped at the two circumferential positions where the sliding resistance of the rotating body 30 with respect to the inner tray body 20 increases. Thereby, unintended delivery of the contents can be reliably suppressed.

  In this embodiment, the maximum distance between the radially inner end of the rib 23e and the inner peripheral surface of the inner cylindrical wall 23 in plan view is the outer distance at the circumferential position where the notch 31b of the rotating shaft 31 is not formed. It comprised so that it might become shorter than a diameter. By adopting such a configuration, the rib 23e more reliably generates the sliding resistance of the rotating body 30 with respect to the inner tray body 20 when contacting the male screw portion 31a at the circumferential position where the notch 31b is not formed. be able to. Therefore, the rotation of the rotating body 30 can be stopped more reliably at the circumferential position (see FIGS. 8 and 9) where the sliding resistance of the rotating body 30 with respect to the inner tray body 20 increases. Thereby, unintended delivery of the contents can be reliably suppressed.

  The present invention contains, for example, contents formed in a stick shape such as cosmetics (lipstick, lip balm, stick eye shadow, etc.), glue, or medicine, and the user draws out and uses the contents in a necessary amount. It can be used for a feeding container.
