[0014] Hereinafter, a dispensing container according to one embodiment of the present invention will be described with reference to the drawings.

[0015] In Figure 1, reference numeral 1 denotes a dispensing container according to one embodiment of the present invention. The dispensing container 1 is a cosmetic dispensing container into which a core material C (see Figure 3) serving as a solid material such as lipstick can be inserted and removed. Figure 2 shows a state in which the dispensing member 2 has been extended to its limit from the dispensing container 1. Figure 3 also shows an enlarged view of the dispensing container 1 equipped with the core material C, with the core material C being extended from the dispensing container 1 during use.

[0016] Referring to Figure 1, the dispensing container 1 comprises: a dispensing member 2 having a center shaft 8 mounted on a middle tray 7 on which a core material C (not shown) can be placed; a case tube 3 in which the dispensing member 2 is housed and which has a guide protrusion 12 that guides a guide recess 11 provided on the middle tray 7 so that the dispensing member 2 can slide in the axial direction; an operating tube 4 that can rotate around its axis relative to the case tube 3; a first screwing portion 5 that screws together the center shaft 8 and the operating tube 4 so that by rotating the operating tube 4 in one direction of rotation, the dispensing member 2 is advanced to one side in the axial direction, and by rotating the operating tube 4 in the other direction of rotation, the advancing member 2 is advanced to the other side in the axial direction; and a second screwing portion 6 that screws together the case tube 3 and the operating tube 4 so that by rotating the operating tube 4 in one direction of rotation, the case tube 3 is advanced to the other side in the axial direction, and by rotating the operating tube 4 in the other direction of rotation, the case tube 3 is advanced to one side in the axial direction. In addition, the dispensing container 1 according to this embodiment is provided with a cap 50 that closes the dispensing opening A of the case cylinder 3.

[0017] Here, the "axial direction" refers to the direction in which the central axis O (hereinafter also referred to as "axis O") of the dispensing container 1 extends. However, in this embodiment, the dispensing member 2, the case cylinder 3 and the operating cylinder 4 are arranged coaxially by using the axis O as a common central axis.

[0018] Furthermore, in the dispensing container 1, "one side in the axial direction" refers to the direction in which the dispensing member 2 or the case tube 3 is advanced so as to move away from the operating tube 4 (also referred to as the "advance direction"). In contrast, in the dispensing container 1, "the other side in the axial direction" refers to the direction in which the dispensing member 2 or the case tube 3 is advanced so as to move closer to the operating tube 4 (also referred to as the "advance direction").

[0019] Next, the "rotation direction" refers to the circumferential direction around the axis O. In the dispensing container 1, "one side of the rotation direction" refers to the direction in which the operating tube 4 rotates (dispensing rotation direction) so that the dispensing member 2 is dispensed from the operating tube 4 by the first screw portion 5. However, when the operating tube 4 is rotated in the dispensing rotation direction, the case tube 3 is inserted into the operating tube 4 by the second screw portion 6. In contrast, in the dispensing container 1, "the other side of the rotation direction" refers to the direction in which the operating tube 4 rotates (retracting rotation direction) so that the dispensing member 2 is inserted into the operating tube 4. Note that Figures 1 and 2 show the rotation direction when the operating part 4 is rotated relative to the case tube 3. However, as described below, when the operating tube 4 is rotated in the retracting rotation direction, the case tube 3 is inserted from the operating tube 4 by the second screw portion 6. Therefore, the rotation direction shown in Figures 4 and 5 described below is shown as the rotation direction when the dispensing member 2 rotates relative to the case tube 3.

[0020] In this embodiment, the first screw portion 5 is configured by an annular inner protrusion 5a provided on the operation cylinder 4 and a spiral groove 5b provided on the center shaft 8 of the delivery member 2.

[0021] In this embodiment, the control tube 4 is composed of an outer tube 4a and an inner tube 4b. In this embodiment, the outer tube 4a and the inner tube 4b are arranged coaxially with the axis O as a common central axis. In this embodiment, the inner tube 4b is fixed non-rotatably inside the outer tube 4a. As a result, when the outer tube 4a is rotated in the circumferential direction around the axis O, the inner tube 4b can be rotated together with the outer tube 4a as the control tube 4 in the same direction as the outer tube 4a.

[0022] In this embodiment, the annular inner protrusion 5a is provided on the inner circumferential surface of the inner cylinder 4b. In this embodiment, the annular inner protrusion 5a is provided on the end of the inner circumferential surface of the inner cylinder 4b in the ejection direction (one end in the axial direction). In this embodiment, the annular inner protrusion 5a protrudes radially inward from the inner circumferential surface of the inner cylinder 4b. In addition, in this embodiment, the annular inner protrusion 5a extends annularly around the entire circumferential direction around the axis O.

[0023] Here, the radial direction refers to a direction perpendicular to the axis O (also referred to as the "axis-perpendicular direction"). In addition, the radial direction side closer to the axis O is referred to as the radially inner side (also referred to as the "axis-perpendicular inner side"). On the other hand, the radial direction side farther from the axis O is referred to as the radially outer side (also referred to as the "axis-perpendicular outer side").

[0024] In contrast, in this embodiment, the helical groove 5b is a helical groove formed axially between helical protrusions provided on the outer peripheral surface of the center shaft 8. In this embodiment, the helical groove 5b extends helically in the axial direction so as to rotate around the axis O. However, the helical groove 5b may be a helical groove provided on the outer peripheral surface of the center shaft 8.

[0025] In this embodiment, the first screwing portion 5 is configured to screw the spiral groove 5b of the delivery member 2 into the annular inner protrusion 5a of the control cylinder 4. This allows the delivery member 2 and the control cylinder 4 to move relatively in the axial direction while rotating relatively in the circumferential direction around the axis O along the spiral groove 5b.

[0026] However, in this embodiment, the guide recess 11 provided on the inner tray 7 of the feed member 2 is fitted into the guide protrusion 12 provided on the case cylinder 3 so as to be slidable in the axial direction. As a result, in this embodiment, the feed member 2 is assembled to the case cylinder 3 so as not to rotate around the axis O. That is, in this embodiment, the feed member 2 rotates integrally with the case cylinder 3 in the circumferential direction around the axis O. As a result, the feed member 2 can be moved relative to the operation cylinder 4 in the axial direction along the spiral groove 5b by rotating the operation cylinder 4 around the axis O.

[0027] In other words, the first screwing portion 5 screws together the center shaft 8 and the operating tube 4 so that the operating tube 4 is rotated in the output rotation direction to extend the output member 2 from the operating tube 4, while the operating tube 4 is rotated in the input rotation direction to extend the output member 2 into the operating tube 4.

[0028] In this embodiment, the second screw portion 6 is configured by a spiral groove 6a provided in the operation cylinder 4 and an annular inner protrusion 6b provided in the case cylinder 3.

[0029] In this embodiment, the helical groove 6a is a helical groove formed between the axially spaced helical protrusions provided on the outer peripheral surface of the inner cylinder 4b. In this embodiment, the helical groove 6a extends helically in the axial direction so as to rotate around the axis O. However, the helical groove 6a may be a helical groove provided on the outer peripheral surface of the inner cylinder 4b.

[0030] In contrast, in this embodiment, the annular inner protrusion 6b is provided on the inner circumferential surface of the case tube 3. In this embodiment, the annular inner protrusion 6b is provided on the inserting direction side end (the other axial side end) of the inner circumferential surface of the case tube 3. In this embodiment, the annular inner protrusion 6b protrudes radially inward from the inner circumferential surface of the case tube 3. In this embodiment, the annular inner protrusion 6b extends annularly around the entire circumferential direction around the axis O.

[0031] In this embodiment, the second screwing portion 6 is configured to screw the spiral groove 6a of the operation tube 4 into the annular inner protrusion 6b of the case tube 3. This allows the case tube 3 and the operation tube 4 to move relatively in the axial direction while rotating relatively in the circumferential direction around the axis O along the spiral groove 6a.

[0032] However, in this embodiment, the spiral rotation direction of the spiral groove 6a of the second screw portion 6 is opposite to the spiral rotation direction of the spiral groove 5b of the first screw portion 5. For example, when the dispensing container 1 is viewed in the axial direction from the feed-in direction end, if the spiral groove 5b of the first screw portion 5 extends to rotate clockwise in the dispensing direction, the spiral groove 6a of the second screw portion 6 extends to rotate counterclockwise in the dispensing direction. As a result, by rotating the operation cylinder 4 circumferentially around the axis O, the case cylinder 3 can be moved relative to the operation cylinder 4 along the spiral groove 6a in the axial direction opposite to the dispensing member 2.

[0033] In other words, the second screwing portion 6 screws together the case tube 3 and the operating tube 4 so that the case tube 3 is inserted into the operating tube 4 by rotating the operating tube 4 in the extension rotation direction, and the case tube 3 is extended from the operating tube 4 by rotating the operating tube 4 in the insertion rotation direction.

[0034] For example, referring to Fig. 1, when the operating cylinder 4 is rotated in the dispensing rotation direction, the dispensing member 2 in the initial state of Fig. 1 is advanced by the first screw portion 5 toward the dispensing outlet A of the case cylinder 3 as shown in Fig. 2. At the same time, when the operating cylinder 4 is rotated in the dispensing rotation direction, the case cylinder 3 in the initial state of Fig. 1 is advanced by the second screw portion 6 into the inside of the operating cylinder 4 as shown in Fig. 2. As a result, by rotating the operating cylinder 4 in the dispensing rotation direction, the dispensing container 1 can quickly make the inner tray 7 reach the dispensing outlet A (opening at one end in the axial direction) of the case cylinder 3 while limiting the amount of operating rotation of the operating cylinder 4. In other words, with the dispensing container 1, the dispensing state shown in Fig. 2 can be quickly achieved by rotating the operating cylinder 4 in the dispensing rotation direction.

[0035] Furthermore, with the dispensing container 1, when the operating cylinder 4 is rotated in the insertion rotation direction, which is the opposite direction to the dispensing rotation direction, the dispensing member 2 in the dispensing state of Fig. 2 is fed into the case cylinder 3 by the first screw portion 5, as shown in Fig. 1. At the same time, when the case cylinder 3 in the dispensing state of Fig. 2 is rotated in the insertion rotation direction, the second screw portion 6 is fed out from the inside of the operating cylinder 4, as shown in Fig. 1. As a result, by rotating the operating cylinder 4 in the insertion rotation direction, the dispensing container 1 can quickly store the inner tray 7 inside the case cylinder 3 while limiting the amount of operation rotation of the operating cylinder 4. In other words, with the dispensing container 1, by rotating the operating cylinder 4 in the insertion rotation direction, it can quickly return to the initial state shown in Fig. 1.

[0036] In the first screw engagement portion 5, the annular inner protrusion 5a provided on the inner tube 4b can be a helical protrusion that screws into the helical groove 5b of the center shaft 8. In this case, the helical protrusion (equivalent to 5a) provided on the inner tube 4b corresponds to the female thread, and the helical groove 5b provided on the center shaft 8 corresponds to the male thread that screws into the helical groove (equivalent to 5a).

[0037] In the second screwing portion 6, the annular inner protrusion 6b provided on the case cylinder 3 can be a helical protrusion that screws into the helical groove 6a of the inner cylinder 4b. In this case, the helical protrusion (equivalent to 6b) provided on the case cylinder 3 corresponds to the internal thread, and the helical protrusion formed between the axial portions of the helical groove 6a provided on the inner cylinder 4b corresponds to the external thread that screws into the helical protrusion (equivalent to 6b).

[0038] The middle plate 7 has at least one slit 13 that holds the core material C when the operating tube 4 is rotated in the insertion rotation direction and the guide protrusion 12 of the case tube 3 presses the guide recess 11 of the middle plate 7 in the insertion rotation direction (the other side of the rotation direction).

[0039] 4 shows the feed member 2 from the side of the inner tray 7. In this embodiment, the inner tray 7 is circular when viewed in the direction perpendicular to the axis, as shown in FIG.

[0040] As shown in Figure 4, in this embodiment, at least one slit 13 is formed by a circumferentially extending portion 13a extending circumferentially around the center shaft 8, and an axially perpendicular portion 13b extending from the insertion rotation direction side end (the other rotation direction side end) 13e1 of the circumferentially extending portion 13a toward the outer peripheral surface of the center plate 7 and opening onto the outer peripheral surface of the center plate 7.

[0041] In this embodiment, the circumferentially extending portion 13a of the slit 13 is preferably provided at a position in contact with the outer peripheral surface of the center shaft 8. In this embodiment, the circumferentially extending portion 13a of the slit 13 is formed by cutting out a portion of the outer peripheral surface of the center shaft 8, as shown in Fig. 4. In this embodiment, the axis-perpendicular portion 13b of the slit 13 extends in the radial direction (axis-perpendicular direction) when viewed in the axial direction, as shown in Fig. 4.

[0042] In addition, in this embodiment, two slits 13 are provided in the inner tray 7. In this embodiment, the two slits 13 are rotationally symmetrical with respect to the axis O. In this embodiment, the two slits 13 coincide with each other every time the inner tray 7 is rotated 180 degrees around the axis O. In this embodiment, the end 13e2 of the circumferentially extending portion 13a of each of the two slits 13 in the dispensing rotation direction (end on one side in the rotation direction) is arranged in a position facing each other across the axis O when viewed in the axial direction, as shown in FIG.

[0043] In this embodiment, each of the two slits 13 forms a clamping portion 14 in the inner tray 7. In this embodiment, the clamping portion 14 is composed of an elastic clamping portion 14a that is elastically deformable and formed in a position facing the unloading rotation direction (one side of the rotation direction) across the slit 13, and a highly rigid clamping portion 14b that is difficult to elastically deform and formed in a position facing the feeding rotation direction (the other side of the rotation direction) across the slit 13.

[0044] In this embodiment, the guide recesses 11 are recesses that are recessed radially inward and provided on the outer peripheral surface of the inner tray 7, as shown in FIG. 4. In this embodiment, the inner tray 7 has a plurality of guide recesses 11. In this embodiment, two guide recesses 11 are arranged circumferentially around the axis O with a gap between them. In this embodiment, the two guide recesses 11 are arranged at positions facing each other across the axis O.

[0045] FIG. 5 is a cross-sectional view corresponding to the XX cross section of FIG. 3, schematically illustrating the deformation of the inner tray 7 when the delivery member 2 is fed into the case cylinder 3. In FIG.

[0046] Referring to FIG. 5 , when inserting the inner plate 7 into the case tube 3, rotating the control tube 4 in the insertion rotation direction moves the guide projection 12 of the case tube 3 from the position indicated by the two-dot chain line to the position indicated by the solid line, thereby pressing the inner plate 7 in the insertion rotation direction, as indicated by the symbol F1, inside the guide projection 12 on the inner plate 7. At this time, the elastic clamping portion 14a of the clamping portion 14 elastically deforms like a leaf spring toward the high-rigidity clamping portion 14b, from the position indicated by the two-dot chain line to the position indicated by the solid line. As a result, the core C placed in the slit 13 on the inner plate 7 is clamped within the slit 13 between the elastic clamping portion 14a and the high-rigidity clamping portion 14b. Therefore, when inserting the inner plate 7 into the case tube 3, rotating the control tube 4 in the insertion rotation direction inserts the inner plate 7 into the case tube 3 while gripping and holding the core C within the slit 13.

[0047] On the other hand, when the inner tray 7 is to be fed into the case tube 3, if the operating tube 4 is rotated in the feeding rotation direction, which is the opposite direction to the feeding rotation direction, the guide protrusion 12 of the case tube 3 moves from the position shown by the solid line to the position shown by the two-dot chain line, thereby pressing the inner tray 7 in the feeding rotation direction, as indicated by the symbol F2, inside the guide protrusion 12 provided on the inner tray 7. At this time, the elastic clamping portion 14a of the clamping part 14 is maintained in its initial state shown by the two-dot chain line without substantially elastic deformation. However, in this case, the core material C arranged in the inner tray 7 is pushed out toward the feeding outlet A of the case tube 3 together with the inner tray 7 as the feeding member 2 is fed out.

[0048] In FIG. 6, the delivery member 2 is shown in a schematic, partially cross-sectional view.

[0049] In this embodiment, at least one slit 13 extends all the way to the center shaft 8. In this embodiment, the center shaft 8 has a connection end 8a with the center plate 7 formed by a neck with a smaller diameter than the spiral groove 5b. As shown in FIG. 6, in this embodiment, the circumferentially extending portion 13a of the slit 13 forms a notched groove that extends axially and circumferentially on the outer circumferential surface of the connection end 8a of the center shaft 8.

[0050] Additionally, in this embodiment, the delivery member 2 has a recess 15 on the placement surface 7F of the inner tray 7. In this embodiment, the placement surface 7F is the end surface of the inner tray 7 in the delivery direction (the end surface on one side in the axial direction). In this embodiment, the recess 15 opens to the placement surface 7F. In this embodiment, the recess 15 is a so-called blind hole that extends into the interior of the center shaft 8. In this embodiment, a core material C is placed on the placement surface 7F of the inner tray 7. In this embodiment, the core material C is filled in the slit 13 and the recess 15, as shown in FIG. 3.

[0051] Furthermore, in this embodiment, the inner tray 7 has a discharge direction outer peripheral surface (one axial side outer peripheral surface) 16 and a feed direction outer peripheral surface (the other axial side outer peripheral surface) 17 at positions spaced apart in the axial direction. In this embodiment, an axial central outer peripheral surface 18 recessed radially inward (inward in the direction perpendicular to the axis) is provided between the discharge direction outer peripheral surface 16 and the feed direction outer peripheral surface 17. In this embodiment, the width W16 in the direction perpendicular to the axis of the discharge direction outer peripheral surface 16 (in this embodiment, the diameter of the discharge direction outer peripheral surface 16) is wider than the width W17 in the direction perpendicular to the axis of the feed direction outer peripheral surface 17 (in this embodiment, the diameter of the feed direction outer peripheral surface 17).

[0052] In this embodiment, the ejection direction outer peripheral surface 16 is the ejection direction end (one axial end) of the inner tray 7. In this embodiment, the arrangement surface 7F is the ejection direction end face (one axial end face) of the ejection direction outer peripheral surface 16. In this embodiment, the arrangement surface 7F is a plane extending in the radial direction (perpendicular to the axis).

[0053] 3, in this embodiment, the feed-out direction end (one axial side end) 3a of the case cylinder 3 is disposed closer to the feed-out direction (one axial side) than the feed-out direction end (one axial side end) 12a of the guide protrusion 12. As a result, a step D is provided between the feed-out direction end 3a of the case cylinder 3 and the feed-out direction end 12a of the guide protrusion 12. In this embodiment, the guide protrusion 12 protrudes radially inward from the inner peripheral surface of the case cylinder 3 and extends in the axial direction. In this embodiment, the case cylinder 3 has a plurality of guide protrusions 12. In this embodiment, two guide protrusions 12 are disposed circumferentially around the axis O with a gap therebetween. In this embodiment, the two guide protrusions 12 are disposed at positions facing each other across the axis O.

[0054] In this embodiment, the dispensing direction end 3a of the case cylinder 3 extends in the dispensing direction by an axial length ΔL beyond the dispensing direction end 12a of the guide protrusion 12. That is, in this embodiment, the step D has an axial length ΔL. As shown in FIG. 2 , in this embodiment, the dimension of the axial length ΔL is set so that the guide recess 11 provided on the inner tray 7 deviates from the guide protrusion 12 provided on the case cylinder 3 when the placement surface 7F of the inner tray 7 is aligned with the dispensing direction end 3a of the case cylinder 3. If the guide recess 11 provided on the inner tray 7 deviates from the guide protrusion 12 provided on the case cylinder 3, the dispensing member 2 will rotate idly inside the case cylinder 3 when the dispensing member 2 is rotated around the axis O. As a result, when the operating tube 4 is rotated in the dispensing rotation direction, the dispensing member 2 is not dispensed from the dispensing outlet A of the case tube 3 until the placement surface 7F of the inner tray 7 exceeds the dispensing direction end 3a of the case tube 3.

[0055] Next, an example of a method for operating the delivery container 1 will be described.

[0056] (Maneuvering operation) When using the dispensing container 1 in the initial state shown in Figure 1, the cap 50 is removed from the dispensing container 1. Next, the operating tube 4 is rotated in the dispensing rotation direction. As a result, as shown in Figure 2, the dispensing member 2 is fed out of the case tube 3, and at the same time, the case tube 3 is fed into the inside of the operating tube 4. According to the dispensing container 1, the core material C is fed out through the feeding opening A of the case tube 3 as the dispensing member 2 is fed out of the operating tube 4. As a result, the core material C arranged on the placement surface 7F of the inner tray 7 is fed out early from the feeding opening A of the case tube 3, as shown in Figure 3.

[0057] (Carry-over operation) On the other hand, when carrying or storing the dispensing container 1, the operating tube 4 is rotated in the inserting rotation direction from the state shown in Fig. 3 (however, here, the state shown in Fig. 2 is used as an example). As a result, as shown in Fig. 1, the dispensing member 2 is advanced into the case tube 3, and at the same time, the case tube 3 is advanced from the operating tube 4. As a result, the inner tray 7 is quickly housed inside the case tube 3, as shown in Fig. 1.

[0058] Here, with the dispensing container 1, the dispensing member 2 is fed into the case tube 3 while gripping and holding the core material C placed inside the slit 13 due to the elastic deformation of the inner tray 7, which has a slit 13. For this reason, in this embodiment, the inner tray 7 does not have the depth required to hold the core material C, and the placement surface 7F of the inner tray 7 can be a flat surface. As a result, the core material C placed on the inner tray 7 can be fed out and inserted and used until the placement surface 7F of the inner tray 7 coincides with the dispensing direction end 3a of the case tube 3, as shown in FIG. 2. Therefore, with the dispensing container 1, the core material C can be fed out and inserted, and the remaining core material C can be removed from the placement surface 7F of the inner tray, thereby reducing the amount of core material C that is discarded.

[0059] The conventional dispensing container described above uses a deep inner tray 7 to hold the core material C, and therefore requires an additional extrusion member (second operating tube) to dispense the core material C held in the inner tray 7.

[0060] In contrast, with the dispensing container 1, when the core material C is to be dispensed from inside the case tube 3, the operating tube 4 is rotated in the dispensing rotation direction, and the core material C placed on the middle tray 7 is dispensed from inside the case tube 3 together with the dispensing member 2.

[0061] Furthermore, according to the dispensing container 1, when the core material C is fed into the case tube 3, by rotating the operating cylinder 4 in the feeding rotation direction, as the dispensing member 2 is fed into the case tube 3, the core material C interposed in the slit 13 formed in the inner tray 7 is clamped between the elastic clamping portion 14a and the high-rigidity clamping portion 14b by elastically deforming, like a leaf spring, the elastic clamping portion 14a of the clamping portion 14 formed by the slit 13 toward the high-rigidity clamping portion 14b. In other words, according to the dispensing container 1, when the core material C is fed into the case tube 3, by rotating the operating cylinder 4 in the feeding rotation direction, the core material C placed in the inner tray 7 is firmly held inside the slit 13 formed in the inner tray 7. As a result, the dispensing member 2 is fed into the case tube 3 with the inner tray 7 gripping and holding the core material C. Therefore, according to the dispensing container 1, when the core material C is fed into the case cylinder 3, it is sufficient to simply rotate the operating cylinder 4 in the feeding rotation direction without using any other operating member.

[0062] With the dispensing container 1, there is no need to constantly hold the core material C on the inner tray 7. Therefore, with the dispensing container 1, there is no need to use a deep inner tray as the inner tray 7, as with conventional dispensing containers. Therefore, with the dispensing container 1, there is no need to provide an additional pushing member (second operating cylinder) for feeding out the core material C held on the inner tray 7 in order to reduce the amount of remaining waste.

[0063] Therefore, the dispensing container 1 can feed and unfeed the core material C while minimizing the amount of core material C that remains to be discarded, and is a dispensing container with a simple configuration.

[0064] According to the dispensing container 1, the core material C is fixed to or fitted into the slit 13 provided in the inner tray 7, so that the core material C is held in the inner tray 7 without deepening the inner tray 7. Therefore, in this case, the core material C can be more reliably fed out and fed in.

[0065] In addition, the dispensing container 1 has two screw threads, a first screw thread 5 and a second screw thread 6, which function to advance the case cylinder 3 into the operation cylinder 4 when the dispensing member 2 is advanced, and to advance the case cylinder 3 from the operation cylinder 4 when the dispensing member 2 is advanced. This allows the inner tray 7 to be advanced early during the dispensing operation, and at the same time, allows the inner tray 7 to be stored early during the insertion operation.

[0066] As shown in FIG. 1 , for example, in this embodiment, the case tube 3 is provided with a sliding resistance portion 19 for applying sliding resistance to the operating unit 4. In this embodiment, the sliding resistance portion 19 is composed of an elastic piece 19a formed by a cutout hole 3C provided in the case tube 3 and a pressing protrusion 19b protruding radially outward (outward in the direction perpendicular to the axis) from the elastic piece 19a. When the operating tube 4 is assembled to the case tube 3, the pressing protrusion 19b elastically presses the inner circumferential surface of the operating tube 4 (in this embodiment, the inner circumferential surface of the outer tube 4a) radially outward. As a result, in this embodiment, the sliding resistance portion 19 applies sliding resistance to the operating tube 4 in the circumferential direction when the operating tube 4 rotates around the axis O. According to this embodiment, by applying rotational resistance to the operating tube 4 during rotation, the operating tube 4 can be stably held at a desired rotational position of the case tube 3.

[0067] In this embodiment, the slits 13 extend all the way to the center shaft 8, as shown in FIG. 6. In this case, the elastic clamping portion 14a of the clamping portion 14 formed by the slits 13 can be elastically deformed to a greater extent. This allows the core C to be held more firmly inside the slits 13. Therefore, in this case, the core C can be fed in more reliably. Furthermore, in this case, the core C is held in the inner tray 7 by being fixed to or fitted into the larger slits 13. Therefore, in this case, the core C can be fed out and fed in more reliably.

[0068] In this embodiment, the feeding member 2 has a recess 15 on the placement surface 7F of the inner tray 7. In this case, as shown in Fig. 3, the core C is fixed to or fitted into the recess 15 provided in the inner tray 7, and is thereby held in the inner tray 7 without deepening the inner tray 7. Therefore, in this case, the core C can be more reliably fed out and fed in.

[0069] In this embodiment, the inner tray 7 has a discharge-direction outer peripheral surface 16 and a feed-in direction outer peripheral surface 17 spaced apart in the axial direction. The axial width W16 of the discharge-direction outer peripheral surface 16 is wider than the axial width W17 of the feed-in direction outer peripheral surface 17. In this case, by ensuring the axial width W16 of the discharge-direction outer peripheral surface 16 is wide, the area of the placement surface 7F of the inner tray 7 on which the core material C is placed can be increased. In addition, in this case, the axial width W17 of the feed-in direction outer peripheral surface 17 is narrower than the axial width W16 of the discharge-direction outer peripheral surface 16. This reduces contact with the guide protrusion 12 of the case tube 3 compared to when the axial width W17 of the feed-in direction outer peripheral surface 17 and the axial width W16 of the discharge-direction outer peripheral surface 16 are the same. Therefore, in this case, the area of the placement surface 7F of the inner tray 7 on which the core material C is placed can be increased, and the feed-in and feed-out of the feed member 2 can be performed smoothly.

[0070] 2, in this embodiment, the dispensing direction end 3a of the case cylinder 3 is disposed closer to the dispensing direction than the dispensing direction end 12a of the guide protrusion 12. In this case, when the operation cylinder 4 is rotated in the dispensing rotation direction, the dispensing member 2 is not dispensed from the dispensing opening A of the case cylinder 3 until the arrangement surface 7F of the inner tray 7 exceeds the dispensing direction end 3a of the case cylinder 3, as shown in FIG. 2. Therefore, in this case, even when the operation cylinder 4 is rotated excessively in the dispensing rotation direction, the dispensed inner tray 7 can be accommodated inside the case cylinder 3. In particular, as in this embodiment, if the arrangement surface 7F of the inner tray 7 is positioned so that the guide recess 11 provided on the inner tray 7 is disengaged from the guide protrusion 12 provided on the case cylinder 3 when the arrangement surface 7F of the inner tray 7 is aligned with the dispensing direction end 3a of the case cylinder 3, the core material C on the arrangement surface 7F of the inner tray 7 can be used to the maximum extent.

[0071] 4, in this embodiment, the slit 13 is formed by a circumferentially extending portion 13a that extends circumferentially around the center shaft 8, and an axis-perpendicular portion 13b that extends from the insertion rotation direction end 13e1 of the circumferentially extending portion 13a toward the outer peripheral surface of the inner tray 7 and opens onto the outer peripheral surface of the inner tray 7. In this case, the delivery member 2 can be easily manufactured.

[0072] As described above, exemplary embodiments of the present invention have been described above, but the present invention is not limited to these embodiments and can be modified in various ways without departing from the spirit of the present invention. The core material C is not limited to lipstick, and examples thereof include stick-type cosmetics such as eyeliner, eyebrow pencil, and lip gloss, but is not limited to cosmetics such as stick glue.
