Description

Technical Field

[0001] The present invention relates to a feeding container capable of feeding a rod-shaped body, a storage part with a feeding mechanism serving as a refill for the feeding container, and a lower operation mechanism attachable to the storage part with the feeding mechanism.

Background Art

[0002] In recent years, from the viewpoints of ease of use and design, solid cosmetics in a rod shape with a non-circular cross-sectional shape, particularly an elliptical cross-sectional shape or a polygonal cross-sectional shape, have been increasingly used. Along with this, feeding containers having a non-circular cross-sectional shape have been proposed. Among such feeding containers, a so-called dial-type feeding configuration has been proposed in which a part of the peripheral wall at the lower part of the container body is open and a rotation operation part is provided at that part so that the feeding operation can be performed with one hand (Patent Document 1).

[0003] On the other hand, in a feeding container for feeding a general cylindrical solid cosmetic, from the viewpoint of reducing the amount of waste of the outer container and reducing the load on the environment, a cartridge-type feeding container in which the part holding the content can be separated from the operating body has also been proposed (for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the dial-type feeding container that can be operated with one hand, cartridge conversion (refill) has not been considered.

[0006] In Patent Document 2, a mechanism for feeding out the contents is provided on the cartridge side. Even when it is not attached to the lower operating body, when the lower end of the shaft portion of the cartridge is rotated, this feeding-out mechanism operates. For this reason, although it is conceivable that a user purchases only the cartridge and uses it without attaching the operating body, such a usage state is not aesthetically pleasing. Further, for example, when the cartridge is placed in a cosmetic pouch or the like and a rotational force is applied to the lower end portion of the cartridge by an external force during transportation, it may rotate inadvertently and the contents may be fed out contrary to the intention, which may stain other cosmetics, the inside of the pouch, or the hands when taking it out. In addition, since there are irregularities for engagement at the lower end of the shaft portion of the cartridge, there is also a risk of damaging other cosmetics in the cosmetic pouch. Therefore, it is recommended that the cartridge be used in combination with the lower operating mechanism rather than alone.

[0007] Therefore, in view of the above circumstances, an object of the present invention is to provide a feeding-out container in which a storage portion with a feeding-out mechanism for holding the contents can be replaced as a refill and the inadvertent feeding-out of the refill alone can be suppressed.

Means for Solving the Problems

[0008] To solve the above problems, in one aspect of the present invention, a feeding-out container comprising a lower operating mechanism and a storage portion with a feeding-out mechanism that can be connected as a refill to the lower operating mechanism, wherein the storage portion with the feeding-out mechanism has an outer case having a bottom wall with a central hole formed therein and an outer cylinder, a lifting body having a dish portion for holding a rod-shaped member and a shaft portion located on the rear end side of the dish portion, has a feeding-out cylinder that holds the shaft portion of the lifting body and a part of which protrudes downward from the central hole of the bottom wall of the case, wherein the lower operating mechanism has a haori cylinder that engages with the case, and an operating body that is exposed from a part of the haori cylinder and can operate the lifting body to feed it out. In the bottom wall of the case, at least a pair of slits extend to the outer peripheral side from the edge of the central hole, so that a vent piece is provided which can be deformed into a cantilever beam shape with the central hole side as a free end. When the accommodating part with the feeding mechanism is connected to the lower operating mechanism, the feeding cylinder rotates with respect to the case, so that the lifting body can move axially. On the outer peripheral surface of the feeding cylinder, when the accommodating part with the feeding mechanism is not connected to the lower operating mechanism, a stepped portion is provided which contacts a part of the vent piece and restricts the rotation of the feeding cylinder with respect to the case. Provide a feeding container.

Advantages of the Invention

[0009] According to one aspect, in the feeding container, the accommodating part with the feeding mechanism for holding the content can be replaced as a refill, and the feeding contrary to the intention of the refill alone can be suppressed.

Modes for Carrying Out the Invention

[0011] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the following drawings, the same reference numerals are given to the same components, and redundant explanations may be omitted.

[0012] The present invention relates to a feeding container capable of feeding a rod-shaped body, a storage portion with a feeding mechanism that serves as a refill for the feeding container, and a lower operating mechanism that can be attached to the storage portion with the feeding mechanism.

[0013] Here, as the rod-shaped body accommodated in the feeding container of the present invention and capable of being fed out, it may include rod-shaped cosmetics and rod-shaped bodies other than cosmetics.

[0014] Examples of the rod-shaped cosmetics may include lipstick, lip cream, concealer, stick eyeshadow, stick foundation, stick-shaped beauty essence, and stick-shaped moisturizer.

[0015] Examples of the rod-shaped bodies other than cosmetics may include stick-shaped perfume, stick-shaped antiperspirant, stick-shaped sunscreen, stick-shaped medicine, stick-shaped insect repellent, stick-shaped solid detergent, stick paste, stick adhesive, eraser, toy imitating lipstick, or foods such as cheese and butter.

[0016] In addition, the rod-shaped body may include, in addition to the solid substance formed in a predetermined shape, a material having a viscosity of a certain level or more and capable of maintaining a predetermined shape, such as a viscoelastic material.

[0017] <Overall Configuration> The overall configuration of the feeding container of the present invention will be described with reference to FIGS. 1 to 6. FIG. 1 is a cross-sectional view of a main part of a feeding container according to an embodiment of the present invention. FIG. 2 is a view showing a state in which the feeding container according to the embodiment is disassembled into a storage portion with a feeding mechanism and a lower operating mechanism.

[0018] The feeding container 7 has a case 1, a lifting body 2, a feeding cylinder 3, a trouser cylinder 4, an operating body 5, and a bottom cover 6. A cap γ (an overcap, see Fig. 2) can be engaged with the feeding container 7.

[0019] As shown in Fig. 2, the feeding container 7 of the present invention can be disassembled into a storage part α with a feeding mechanism and a lower operating mechanism β. The storage part α with a feeding mechanism can be a refill that can be replaced with respect to the lower operating mechanism β.

[0020] The storage part α with a feeding mechanism has a case 1, a lifting body 2, and a feeding cylinder 3. The lower operating mechanism β has a trouser cylinder 4, an operating body 5, and a bottom cover 6.

[0021] As shown in Fig. 2, the storage part α with a feeding mechanism can be made into a refill that can be replaced with respect to the lower operating mechanism β together with a rod-shaped body C (for example, a rod-shaped cosmetic, see Fig. 6). That is, with respect to the lower operating mechanism β, it can be replaced and used from the empty storage part α with a feeding mechanism to a new refill of the same shape.

[0022] In the storage part α with a feeding mechanism that can be replaced as a refill, the upper end of the refill α and the upper end of the case 1 can be covered with a film or a simple cap. Thereby, the storage part α with a feeding mechanism as a refill can be distributed alone.

[0023] Referring to Fig. 1, the case 1 is an upper case with an open upper part and serves as a refill case. The case 1 has an upper outer cylinder 11, a lower outer cylinder 12, a bottom wall 13, two vent pieces 16, 16, and a standing cylinder 17 standing up from the bottom wall 13. A circumferential protrusion 17P is formed on the inner peripheral surface of the standing cylinder 17. In the standing cylinder 17, the diameter is larger at the lower part. Also, in the standing cylinder 17, on the upper side of the vent pieces 16, 16, slit-shaped intermittent parts 18, 18 (see Fig. 4(b)) extending in the vertical direction are formed, so that the standing cylinder 17 is interrupted at the parts of the intermittent parts 18, 18 in the circumferential direction.

[0024] The upper outer cylinder 11 and the lower outer cylinder 12 of Case 1 are elliptical in cross section. In addition, the details of the lower structure of Case 1 will be described in detail together with FIG. 4.

[0025] The lifting body 2 is a stick holder having a dish part 21 for accommodating the rod-shaped body C and a shaft part 25 located on the rear end side of the dish part 21. The dish part 21 has a holding cylinder 22 for holding the side surface of the rod-shaped body C and a dish bottom 23 for holding the bottom surface of the rod-shaped body C. On the upper surface of the dish bottom 23, a retaining projection 24 which is an upward projection is provided. The shaft part 25 is a spiral shaft (screw shaft) provided with spiral projections 26 on the outer peripheral surface.

[0026] The dish part 21 of the lifting body 2 is movable up and down along the inner circumference of the upper outer cylinder 11 of the case 1. Since the holding cylinder 22 of the dish part 21 of the lifting body 2 is elliptical in cross section, the rotation of the lifting body 2 is restricted with respect to the case 1 having an elliptical cross section.

[0027] The feeding cylinder 3 is located inside the standing cylinder 17 of the case 1, and when it becomes a single accommodating part α with a feeding mechanism as shown in FIG. 2, a part of it protrudes downward from the bottom wall 13 of the case 1. The feeding cylinder 3 is a lifting body holder that rotatably holds the shaft part 25 of the lifting body 2. The details of the outer peripheral surface of the feeding cylinder 3 will be described in detail together with FIG. 5. A circumferential groove 36 is formed near the upper end of the outer peripheral surface of the upper cylinder 31 of the feeding cylinder 3 and engages with the circumferential projection 17P of the standing cylinder 17 of the case 1.

[0028] Also, in the state of FIG. 1, the vent piece 16 of the case 1 rides on the outer peripheral annular step 33 of the feeding cylinder 3.

[0029] Also, as shown in FIG. 2, a plurality of vertical ribs 39 are formed on the lower outer peripheral surface of the lower cylinder 32 of the feeding cylinder 3 to form a gear in cross section, and the rotation of the operating body 5 is transmitted by the engagement of the plurality of vertical ribs 39 with the teeth of the internal gear 52 of the operating body 5 of the lower operating mechanism β.

[0030] In the refill α, the rod-shaped body C may be attached to the dish portion 21 of the lifting body 2 after being pre-formed into a rod shape, or the material may be filled into the replenishment space formed by the bottom 23 of the dish portion 21 of the lifting body 2 and the inner peripheral surface of the upper portion of the outer cylinder 11 of the case 1 to form the rod-shaped body C.

[0031] Here, with reference to FIGS. 1, 2, and 3, the details of the structure of the case 1 and the feeding cylinder 3 will be described. FIG. 3 is a cross-sectional view of the lower operating mechanism β, where (a) is a long-axis cutaway view corresponding to AA' in FIG. 2, and (b) is a short-axis cutaway view corresponding to the BB' plane in FIG. 2.

[0032] In the lower operating mechanism β, the skirt cylinder 4 includes an upper side wall 41 having an elliptical cross-section, a lower side wall 42, a ring-shaped partition surface 43 with a central hole 44 formed at the inner boundary between the upper side wall 41 and the lower side wall 42, and a hanging cylinder 45 provided so as to hang down from the inner edge of the partition surface 43. The partition surface 43 horizontally partitions the inner space of the side wall 40 composed of the upper side wall 41 and the lower side wall 42. Two tapered upward protrusions 46, 46 protruding upward from a part of the hanging cylinder 45 are provided so as to stand along the inner edge defining the central hole 44.

[0033] Also, in the partition surface 43, in the vicinity of the central hole 44 of the hanging cylinder 45, parallel slit-shaped through holes 47, 47 that are long in the long-axis direction with the central hole 44 in between are formed. The through holes 47 also penetrate the hanging cylinder 45, and the penetrated portion in the hanging cylinder 45 defines four vertically long vertical slits 48. With this configuration, in the partition surface 43, the central region 43R, which is the portion sandwiched between the two through holes 47, 47, can be bent when the feeding cylinder 3 is inserted.

[0034] Further, the upper side wall 41 and the lower side wall 42 of the skirt cylinder 4 have an elliptical cross-section, and an opening window 49 is formed in the long arc portion in the short-axis direction of the lower side wall 42.

[0035] When the accommodating part α with a feeding mechanism is connected to the lower operating mechanism β, the trouser tube 4 and the case 1, both having an elliptical cross-section, are non-rotatably connected. For engagement, a locking projection 12P is provided on the upper part of the outer peripheral surface of the lower outer cylinder 12 of the case 1, and a locking projection 41P is provided at the upper end of the inner peripheral surface of the upper side wall 41 of the trouser tube 4.

[0036] The operating body 5 is a dial mechanism (rotating body) that can be rotated by the user. The operating body 5 has an annular shape with gears on both the outer and inner sides, and a plurality of ribs are provided on the outer surface of the annular main body 50 to form a flat knurl 51. As shown in FIG. 2, the outer peripheral surface on which the flat knurl 51 is formed protrudes from the opening window 49 of the trouser tube 4 and receives a rotational force when operated by the user.

[0037] The inner peripheral surface of the operating body 5 is provided with a plurality of inward teeth to form an internal gear 52. When the accommodating part α with a feeding mechanism is connected to the lower operating mechanism β, the internal gear 52 engages with the vertical rib 39 of the feeding cylinder 3.

[0038] Also, referring to FIGS. 1 and 3, on the bottom cover 6, triple annular rings 62, 63, 64 are provided on the bottom surface 61. The bottom surface 61 of the bottom cover 6 serves as the bottom surface of the lower operating mechanism β. The outer ring 62 rising from the outer edge of the bottom surface 61 is fitted inside the lower side wall 42 of the trouser tube 4.

[0039] The middle ring 63 of the bottom cover 6 is the highest among the annular rings and is located outside the outer peripheral surface of the operating body 5 in the minor axis direction. When the accommodating part α with a feeding mechanism is connected to the lower operating mechanism β, the inner ring 64 of the bottom cover 6 is located inside the inner periphery of the feeding cylinder 3. With this configuration, the bottom cover 6 regulates the lateral position of the feeding cylinder 3 within the lower operating mechanism β.

[0040] Here, with reference to FIGS. 4 and 5, Case 1 and the details of the structure of the pay-out cylinder 3 will be described. FIG. 4 is an explanatory view of Case 1 according to the embodiment, (a) is a bottom perspective view, and (b) is a cross-sectional perspective view. FIG. 5 is an explanatory view of the pay-out cylinder 3 according to the embodiment, (a) is an external view of the pay-out cylinder, and (b) is a cross-sectional perspective view. In FIGS. 4(b) and 5(b), for the purpose of explaining the structure, a view of the part cut off closer to the front side than the center is shown.

[0041] Referring to FIG. 4(a), in the bottom wall 13 which is the bottom of Case 1, a central hole 14 which becomes the hollow part of the standing cylinder 17 is formed, and two pairs of slits 15 extend to the outer peripheral side from the edge of the central hole 14, so that two vent pieces 16, 16 which can be deformed into a cantilever beam shape with the central hole 14 side as the free end are provided. On the lower surface near the free ends of the vent pieces 16, 16, a groove part 16G is formed so as to cross the extending direction of the vent piece 16.

[0042] Also, as shown in FIG. 4(b), the lower part of the standing cylinder 17 has a slightly larger diameter, and intermittent parts 18, 18 are formed on the upper sides of the vent pieces 16, 16. Thereby, the central end sides of the vent pieces 16, 16 can move in the vertical direction without interfering with the standing cylinder 17.

[0043] Referring to FIGS. 5(a) and 5(b), the cylinder part 30 of the pay-out cylinder 3 is composed of an upper cylinder 31 and a lower cylinder 32, and the outer diameter of the lower cylinder 32 is larger than that of the upper cylinder 31. Therefore, the outer boundary between the upper cylinder 31 and the lower cylinder 32 is an outer peripheral annular step 33.

[0044] In the upper cylinder 31, a slit 35 extending in the vertical direction from the tip is formed, and a circumferential groove 36 is formed near the upper end. Also, in the upper cylinder 31, a horizontally long partial groove part is formed in the part where the slit 35 is not formed. On the other hand, an engaging projection 34 is provided on the inner peripheral surface of the upper cylinder 31.

[0045] On the outer peripheral surface of the lower cylinder 32, two strip-shaped groove portions 37, 37 which are recessed portions having a predetermined width in the circumferential direction are formed. The opposing left and right groove side walls 37S of the strip-shaped groove portion 37 come into contact with both side edges of the vent piece 16 of the case 1 and serve as stepped portions for restricting the rotation of the feeding cylinder.

[0046] Also, the groove side wall on the upper end side of the strip-shaped groove portion 37 is a curved upper end surface 37C in which the portion connecting to the outer lower end of the convex portion 33P is convexly curved. Note that the groove side wall on the upper end side of the strip-shaped groove portion 37 may be an inclined surface that is recessed from top to bottom.

[0047] Also, in the lower cylinder 32, above the curved upper end surface 37C of the strip-shaped groove portion 37, a part of the outer peripheral annular step 33 becomes a convex portion 33P that protrudes outward with respect to the strip-shaped groove portion 37.

[0048] On the other hand, a horizontally long hole portion is formed connected to the lower end of the strip-shaped groove portion 37.

[0049] Next, with reference to FIG. 6, the feeding of the rod-shaped body C by the lifting body 2 in the feeding container 7 will be described. FIG. 6 is a cross-sectional view for explaining the feeding in the feeding container 7 according to the embodiment, (a) shows the state where the lifting body 2 has descended the most, and (b) shows the state where the lifting body 2 has ascended the most.

[0050] As described above, the engaging protrusion 34 provided on the inner peripheral surface of the feeding cylinder 3 engages with the spiral protrusion 26 of the shaft portion 25 of the lifting body 2. Then, by the relative rotation of the engaging protrusion 34 of the feeding cylinder 3 with respect to the spiral protrusion 26 of the shaft portion 25, the shaft portion 25 provided with the spiral protrusion 26 moves in the axial direction, and the lifting body 2 whose rotation is restricted by the case 1 can move up and down with respect to the feeding cylinder 3.

[0051] Here, when the storage part α with a feeding mechanism is connected to the lower operating mechanism β, when the feeding cylinder 3 rotates with respect to Case 1, the lifting body 2 can move in the axial direction. Specifically, when lifting the lifting body 2, the operating body 5 is rotated by the user with respect to Case 1 and the trouser tube 4, so that the feeding cylinder 3 rotates with the operating body 5 with respect to Case 1 and the trouser tube 4. Thereby, by relatively rotating the feeding cylinder 3 with respect to the lifting body 2 whose rotation is restricted by Case 1, the lifting body 2 whose rotation is restricted by Case 1 is fed out in the axial direction.

[0052] At this time, since the position of the feeding cylinder 3 is restricted in the vertical direction with respect to Case 1, when the lifting body 2 is lifted, the feeding cylinder 3 rotates with respect to Case 1, and the vertical position with respect to Case 1 does not change.

[0053] Here, as shown in FIG. 6, in the state where the storage part α with a feeding mechanism and the lower operating mechanism β are connected, when the feeding cylinder 3 is rotated with respect to Case 1, the feeding of the lifting body 2 and the rod-shaped body C occurs. However, in the present invention, as shown in FIG. 2, when the storage part α with a feeding mechanism is in a single state as a refill, a mechanism is provided in which the feeding cylinder 3 does not rotate with respect to Case 1.

[0054] Here, the rotation restricting configuration of the feeding cylinder 3 with respect to Case 1 will be described with reference to FIGS. 7 and 8.

[0055] FIG. 7 is an explanatory diagram when the storage part α with a feeding mechanism is engaged with the lower operating mechanism β. In FIG. 7, (a) shows the state immediately before the storage part α with a feeding mechanism is engaged with the lower operating mechanism β, and (b) shows the state where the storage part α with a feeding mechanism is engaged with the lower operating mechanism β. In addition, in FIG. 7, for the sake of explanation, the lifting body 2 is shown omitted.

[0056] FIG. 8 is an enlarged explanatory view of the periphery of the vent piece when the accommodating portion α with a feeding mechanism is engaged with the lower operating mechanism β. In FIG. 8, (a) is a cross-sectional perspective view showing the state of the periphery of the vent piece immediately before the accommodating portion α with a feeding mechanism is engaged with the lower operating mechanism β, and (b) is a cross-sectional perspective view showing the periphery of the vent piece in a state where the accommodating portion α with a feeding mechanism is engaged with the lower operating mechanism β.

[0057] As shown in FIGS. 7(a) and 8(a), when the accommodating portion α with a feeding mechanism is not connected to the lower operating mechanism β, the vicinity of the central hole 14, which is the free end of the vent pieces 16, 16, is fitted into the belt-shaped groove portion 37 of the feeding cylinder 3. Since the vent piece 16 is fitted into the belt-shaped groove portion 37 of the feeding cylinder 3, the rotation of the feeding cylinder 3 with respect to the case 1 is restricted. Specifically, in this state, even if a rotational force is applied to the feeding cylinder 3, the side end of the vent piece 16 contacts the step, which is the left and right groove side walls 37S of the belt-shaped groove portion 37, and thus the rotation of the feeding cylinder 3 with respect to the case 1 is restricted.

[0058] When connecting as shown in FIGS. 7(a) → 7(b), the lower end of the lower cylinder 32 of the feeding cylinder 3 is inserted into the central hole 44 of the partition surface 43 of the skirt cylinder 4, and the accommodating portion α with a feeding mechanism is pushed into the lower operating mechanism β.

[0059] At this time, the upward protrusions 46, 46 located around the central hole 44 of the skirt cylinder 4 of the lower operating mechanism β lift the vent pieces 16, 16, and the free end of the vent piece 16 gets over the convex portion 33P including the curved upper end surface 37C of the feeding cylinder 3 and rides on the outer peripheral annular step 33. At this time, the upper end of the upward protrusion 46 fits into the groove portion 16G of the vent piece 16, so that a force acts straight upward without shifting with respect to the free end of the vent piece 16.

[0060] Here, as shown in FIG. 8(a), the vicinity of the free end on the upper surface of the vent piece 16 is a tapered end 16T that is inclined so that the free end side is lower. On the other hand, as described above, the curved upper end surface 37C, which is the upper groove side surface of the belt-shaped groove portion 37 of the feeding cylinder 3, is a curved surface with an R at a portion corresponding to the corner at the lower end of the outer peripheral surface of the convex portion 33P.

[0061] Therefore, when an upward force is applied from the upward projection 46 to the free end of the vent piece 16, the tapered end 16T of the vent piece 16 contacts the curved upper end surface 37C that is the lower surface of the convex portion 33P which is a part of the outer peripheral annular step 33, and while contacting, climbs over the convex portion 33P, so there is little resistance and it can climb over smoothly.

[0062] And, as shown in FIGS. 7(b) and 8(b), when the free end of the vent piece 16 is lifted onto the outer peripheral annular step 33 which is above the convex portion 33P, the free end of the vent piece 16 is positioned above the left and right groove side walls 37S of the belt-shaped groove portion 37. In this state, when the vent piece 16 rotates around the feeding cylinder 3, there is nothing to block in the circumferential direction. As a result, the rotation restriction state of the feeding cylinder 3 with respect to the case 1 is released, and the feeding cylinder 3 becomes rotatable with respect to the case 1.

[0063] Also, when receiving the pushing force, the locking projection 12P on the outer peripheral surface of the lower outer cylinder 12 of the case 1 climbs over and locks the locking projection 41P on the upper side wall 41 of the skirt cylinder 4, and in a state where the bottom wall 13 of the case 1 and the partition surface 43 of the skirt cylinder 4 are in contact or close proximity, the case 1 and the skirt cylinder 4 engage in a state where they are non-rotatable and restricted in the vertical direction.

[0064] In this way, just by pushing the replaced refill α into the lower operation mechanism β, the replaced refill α can be easily attached to the lower operation mechanism β, and at the same time, the rotation restriction state is released and the feeding container 7 can be easily assembled.

[0065] With such a configuration, in the refill alone, the feeding of the lifting body due to the rotation of the feeding cylinder is prevented, and when the refill and the lower operation mechanism engage, the rotation of the feeding cylinder 3 becomes possible. In this state, by the meshing of the internal gear 52 of the operating body 5 and the vertical rib 39 of the feeding cylinder 3, the feeding of the rod-shaped body C as intended by the user becomes possible by the rotation of the operating body 5.

[0066] (Modification example) In the above description, the vent pieces 16 defined by the two pairs of slits 15 in Case 1 are provided in two in the major axis direction of the bottom wall 13, and the upward protrusions 46 of the lower operation mechanism β are provided in two in the radial direction of the upper surface. However, as long as the number of vent pieces of the case and the upward protrusions of the trouser legs are the same, there may be one, or there may be a plurality of three or more.

[0067] In the above example, the feeding cylinder 3 has a plurality of engaging mechanisms and is integrally formed. However, the feeding cylinder 3 may be formed of a separate cylindrical portion for an upper mechanism that engages with the case and an external gear mechanism of a lower mechanism that engages with the internal gear 52 of the operating body 5. In that case, a plurality of vertical ribs in a gear shape in cross section are formed on the outer peripheral surface at the lower end on the lower mechanism side.

[0068] Also, in the above example, the shaft portion 25 of the lifting body 2 is a spiral shaft provided with spiral protrusions on the outer peripheral surface, and the engaging protrusions 34 are provided on the inner peripheral surface of the feeding cylinder 3. However, one engaging protrusion may be provided on the shaft portion of the lifting body, and the inner peripheral surface of the feeding cylinder 3 may have a shape provided with spiral protrusions (female threads).

[0069] Also, in the above, an example in which the case and the trouser legs have an elliptical cross section is shown. However, the case and the trouser legs may have, for example, a rectangular or rounded rectangular shape in cross section.

[0070] As described above, the preferred embodiments of the present invention have been described in detail.
