    [0001] A stick-shaped material supply container, that is a container for a stick-shaped material, adapted to partially eject said material for use therein. and to retract it after use. As a material feed container, or body, in the shape of a stick and housed in a two-part container, using two pieces of threaded portions to pull out said stick-shaped material by a opening located at a distal end of the container to use said material, a container described in JP-4620606 (document 1 of the patent literature) is known. The stick-shaped material feed container described in Patent Document 1 comprises a guide tube. The guide tube is mounted on the side of the distal end of a main body of the container so that it can be rotated relative to the main body of the container. The guide tube houses a tubular element inside. The tubular element houses inside the material having the shape of a stick. The relative rotation of the main container body and the guide tube in the feed direction, first activates a screwing action by the first threaded portion. When the threaded member reaches the advancing limit in the guide tube and the screwing action by the first threaded portion is stopped, a screwing action by a second threaded portion is activated. The screwing action feeds and advances a moving body. This pulls the stick-shaped material into the tubular member, and the stick-shaped material extends from the opening at the distal end of the guide tube for use. The relative rotation of the container main body and the guide tube in the retraction direction activates a screwing action by the first threaded portion. When the threaded member moves away from the forward limit and is retracted, the tubular member retracts together with the threaded member. Thus, the material in the shape of a stick plunges from the opening of the guide tube to the inside of the guide tube. In this case, with the known stick-shaped material feed container, after use of the stick-shaped material extending from the upper end surface of the tubular member, when the container main body and the guide tube are rotated in the retraction direction, the screwing action by the first threaded portion retracts the tubular member from the feed limit and the stick-shaped material plunges into the guide tube, a region between the upper end surface of the guide tube and this forward limit being a space for the tubular member to advance and retract. However, as the tubular member retracts from the advancing limit, the stick-like material extending from the upper end surface of the tubular member is not held radially on the tubular member. entire circumference in this space. Therefore, if an impact or vibration acts on the container, the stick-like material extending from the upper end surface of the tubular member oscillates in space, which may end in a breakage of the material in the shape of a stick. More particularly, in the case where the viscosity of the stick-shaped material is low and the stick-shaped material has a small diameter, the possibility of breakage increases. For this reason, the object of the invention is to provide a feed container with a stick-like material which can prevent the stick-shaped material from breaking even when the container is subjected to to an impact or vibration.
    [0002] The object of the invention is achieved with a stick-shaped material feed container, comprising a guide tube having an opening at a distal end, the guide tube being provided with a first female thread on an inner peripheral surface; a container main body on which the guide tube is rotatably mounted relative to said body; a tubular member disposed in the guide tube, a stick-shaped material being loaded into a tube portion of the tubular member; a movable body which comprises a piston and a rod portion, the piston being movable in the tubular member to output the stick-shaped material, the rod portion having a second male thread on an outer peripheral surface; and a threaded member comprising a first male thread on an outer peripheral surface and a second female thread on an inner peripheral surface, the first male thread being engaged with the first female thread of the guide tube to form a first threaded portion, the second female thread being engaged with the second male thread of the movable body to form a second threaded portion; relative rotation of the guide tube and the container main body advancing or retracting the thread member together with the tubular member by a screwing action by the first threaded portion; at the same time, when the threaded member and the tubular member advance a predetermined distance, a screwing action by the second threaded portion advancing the movable body to pull out the stick-shaped material so as to ensuring that the stick-shaped material extends from the opening of the guide tube; at a distal end of the tubular member, a plurality of projections being disposed circumferentially, the projections extending forwardly in an axial direction; at one tip end of the guide tube, a groove portion being disposed, the groove portion including a plurality of grooves disposed around an inner peripheral surface, the grooves extending in an axial direction, protrusions of the tubular element engaging in the grooves; on the guide tube, an inner diameter of a convex portion between the circumferentially arranged grooves and an inner diameter of the tubular portion which houses the projections of the tubular member and the material having a stick shape at the rear relative to the projections of the tubular element, having identical dimensions; and the screwing action by the first threaded portion advancing or retracting a distal end of the projections of the tubular member into the groove portion. In other words, the stick-shaped material feed container comprises a guide tube, a container main body, a tubular member, a movable body and a thread member, here a thread and a tapping. The guide tube has an opening at a distal end. The guide tube is provided with a first female thread, and thus a tapping, on an inner peripheral surface. On the main container body is mounted the guide tube so as to be rotatable relative to said body. The tubular element is disposed in the guide tube.
    [0003] A stick-shaped material is loaded into a tube portion of the tubular member. The movable body comprises a piston and a rod portion. The piston is movable in the tubular element to release the material having the shape of a stick. The stem portion has a second male thread, and thus a thread, on an outer peripheral surface. The threaded element comprises a first male thread, thus a thread, on an outer peripheral surface and a second female thread, and thus a thread, on an inner peripheral surface. The first male thread cooperates with the first female thread of the guide tube to form a first threaded portion. And the second female thread cooperates with the second male thread of the movable body to form a second threaded portion. The relative rotation of the guide tube and the container main body causes the thread member to advance or retract together with the tubular member by a screwing action by the first threaded portion. At the same time, when the threaded member and the tubular member advance a predetermined distance, a screwing action by the second threaded portion causes the movable body to advance to pull out the stick-shaped material to ensure that the stick-shaped material extends from the opening of the guide tube. At a distal end of the tubular member, a plurality of projections are disposed on the periphery. The projections extend forwardly in an axial direction. At a tip end of the guide tube, a groove portion is disposed. The groove portion includes a plurality of grooves disposed around an inner peripheral surface. The grooves extend in an axial direction. The projections of the tubular element engage in the grooves. On the guide tube, an inner diameter of a convex portion between the circumferentially arranged grooves and an inner diameter of the tubular portion which houses the projections of the tubular member and the material having a stick shape at the rear relative to the projections of the tubular element have identical dimensions. The screwing action by the first threaded part causes a distal end of the projections of the tubular member to advance or retract into the groove portion.
    [0004] In the stick-shaped material supply container, at a distal end of the tubular member, the plurality of projections are disposed around the periphery. The projections extend forwardly in an axial direction. At a tip end of the guide tube, a groove portion is disposed. The groove portion includes a plurality of grooves disposed around an inner peripheral surface. The grooves extend in an axial direction. The projections of the tubular element engage in the grooves. On the guide tube, an inner diameter of a convex portion between the circumferentially arranged grooves and an inner diameter of the tubular portion which houses the projections of the tubular member and the material having a stick shape at the rear relative to the projections of the tubular element have identical dimensions. The arrangement is such that the screwing action by the first threaded portion advances or retracts a distal end of the projections of the tubular member within the groove portion. Even if the distal ends of the projections of the tubular member are retracted back relative to the distal ends of the grooves of the guide tube (even if the ends are retracted beyond the forward limit), this arrangement supports around the periphery the stick-shaped material extending from the projections of the tubular member to a plurality of portions by internal surfaces of the convex portions between the grooves in the groove portion of the guide tube. This prevents the material in the shape of a stick breaks, even if the container is subjected to impacts or vibrations. Thus, according to the present invention, the container 35 is able to prevent the stick-shaped material from breaking, even if the container is subjected to impacts or vibrations.

Among FIGS. 9 to 11, which represent the tubular element in the retracted state, FIGS. 10 and 11 show the non-material state having the shape of a stick. Figure 10 shows a cross-section at a position without a groove in the guide tube. And Fig. 11 shows the cross-section at the grooved position in the guide tube. In this embodiment, the stick-shaped material is a stick-shaped cosmetic material and the stick-shaped material-carrying container is a feed container having a stick shape. a cosmetic material having the shape of a stick. Since the application of the present invention relates to the stick-shaped cosmetic material, which breaks particularly easily, a stick-like cosmetic material having a low viscosity and a small diameter is used as a cosmetic material. shaped like a stick.
    [0007] However, in the context of the present invention, it is only necessary that the applicable material is a cosmetic material having the shape of a stick. As shown in FIG. 1, a feed container 100 of a stick-shaped cosmetic material as a feed container of a stick-shaped material, comprises a container main body 1 and a guide tube 3 as an external configuration. The main container body 1 forms a half-back portion of the container. The guide tube 3 forms a half-front portion of the container. The guide tube 3 is connected to the main container body 1 so as to be rotatable relative to each other and stationary in an axial direction. As shown in FIG. 2, the container has inside it a threaded element 5, a tubular element 4 and a piston 6x at a distal end. The relative rotation of the main container body 1 with respect to the guide tube 3 causes the threaded element to come out or retract 5. The tubular element 4 houses a cosmetic material M having the shape of a stick. The tubular element 4 advances or retracts together with the outlet or the return of the threaded element 5. The piston 6x is inserted by insertion into the tubular element 4 and abuts on the rear end surface of the cosmetic material M shaped like a stick. The supply container 100 of a cosmetic material in the form of a stick essentially comprises a movable body 6, a pawl spring element 7, a first threaded portion 8 and a second threaded portion 9. The movable body 6 advances or retracts together with the exit or return of the threaded member 5. When the threaded member 5 and the tubular member 4 arrive at a forward limit and the main body of the container 1 and the tube 3 guide turn in the same direction, the moving body 6 advance. The pawl spring element 7 prestresses the threaded member 5 always towards the front face. In response to the relative rotation of the container main body 1 and the guide tube 3, and after the thread member 5 and the tubular member 4 have reached the forward limit, the ratchet spring member 7 has a pawl function with the threaded member 5. The first threaded portion 8 allows the threaded member 5 to advance or retract. The second threaded part 9 ensures the movement of the movable body 6.
    [0008] The main container body 1 is in the form of a cylinder with a closed bottom, as shown in FIGS. 1 and 2. As shown in FIG. 3, the container main body 1 comprises a convex-concave portion la on a circumferential surface. inside the distal end. The convex-concave portion has an annular shape and an irregularity arranged in the axial direction. The convex-concave portion cooperates with the guide tube 3 in the axial direction. As shown in FIG. 2, the main container body 1 has projections lf. The projections 1f extend elongately from a bottom portion to the distal end side on the inner peripheral surface. In order to engage the movable body 6 in a direction of rotation, the plurality of projections, here four projections, are arranged homogeneously, next to each other, all around the circumference (see Figure 12). As shown in Fig. 3, an upper end surface 1b (upper in the container direction as shown in Fig. 3) of the projection 1f is a stepped surface for abutting the rear end surface of the ratchet spring element 7 on this stepped surface. On the main container body 1, a plurality of grooves 1a are uniformly disposed, adjacent each other, all around the circumference, on the inner peripheral surface on the front face with respect to the upper end surface. lb of said main body. The grooves 1c extend in the axial direction and engage the ratchet spring element 7 in the direction of rotation. As shown in Figures 1 and 3, the guide tube 3 has a cylindrical shape. The guide tube 3 comprises a flange portion 3x in the middle in the axial direction. The upper end surface of the container main body 1 abuts on the 3x flange portion. As shown in FIG. 3, a part located on the rear side of the guide tube 3, seen with respect to the flange 3x, is an insertion part which is to be inserted into the main body of the container 1. A part situated on the front side of the guide tube 3, seen with respect to the flange 3x, is a gripping part intended to be gripped by the user during the relative rotation of the main container body 1 and the guide tube 3. As shown in FIG. 13 to 15, a concavo-convex annular portion 3d is disposed on an outer peripheral surface near the flange portion 3x in the insertion portion of the guide tube 3. The concavoconvex portion 3d is engaged in the convex portion. concave the main container body 1 in the axial direction.
    [0009] As shown in FIGS. 14 and 15, a tube hole passing in the axial direction of the guide tube 3 from an opening at the distal end to the vicinity of the distal end is a short hole 3f for the cosmetic material shaped like a stick.
    [0010] Only the cosmetic material M having the shape of a stick advances and retracts through this hole for cosmetic material 3f. The rear end of said hole 3f for cosmetic material is followed by a groove forming portion G (the details are described later). From the rear end of this groove portion to the rear end of the tube hole extends a tube hole 3g. The tube hole 3g has a larger diameter than the hole 3f for a cosmetic material having the shape of a stick. The tubular hole 3g houses the tubular element 4 and the threaded element 5. The tubular element 4 and the threaded member 5 moves (i.e. advances or retracts) into the tube hole 3g. In the middle of the tube hole 3g in the axial direction, a 3m stepped surface is disposed. The diameter of the rear side tube hole with respect to said stepped surface 3m is larger than the diameter of the tube hole on the front side. On the stepped surface 3m, a plurality of grooves 3h (here four grooves) are arranged homogeneously, one next to the other, circumferentially. The grooves 3h extend from said stepped surface 3m to the front face, in the axial direction, to engage the tubular member 4 in the direction of rotation. The grooves 3h also play a role in guiding the projections 4n (the details are described later) of the tubular element 4 to correctly enter the grooves 3n (the details are described later) on the side of the distal end of the guide tube 3. In the 3g tube hole, the tube hole on the front side with respect to the stepped surface 3m exclusively houses the tubular element 4. In the tube hole 3g, the tube hole on the rear side relative to the stepped surface 3m exclusively houses the threaded element 5. A distal end 3j constituting the groove 3h may be the stepped surface corresponding to the forward limit of the tubular element 4. Then, a female thread 3i ( a spiral groove) is disposed on the inner peripheral surface at the rear with respect to the flange portion 3x of the guide tube 3. The female thread 3i constitutes an element of the first threaded portion 8. The female thread 3 i is disposed on a predetermined interval along the axial direction as a first female thread.
    [0011] Between the distal end of the tube hole 3g and the hole 3f for cosmetic material having the shape of a stick, is disposed the groove portion G. The groove portion G is disposed to correspond to a gap where the projection 4n of the tubular member 4 moves (details are described later). Said groove portion G comprises a plurality of grooves 3n (here four grooves) and a convex portion 3p. The grooves 3n are homogeneously arranged, circumferentially adjacent to one another, extend in the axial direction and are installed after the tube hole 3g. The convex portion 3p is formed between the circumferentially disposed grooves 3n and 3n and installed following the hole 3f for a stick-shaped cosmetic material. The inside diameters of the tube hole 3g and the grooves 3n installed after said tube hole 3g are identical diameters. The inner diameters of the hole 3f for the cosmetic material having the shape of a stick and the convex portion 3p installed after the hole 3f for the cosmetic material having the shape of a stick are identical diameters. Thus, on the guide tube 3, the plurality of grooves 3n extending forwardly from the tube hole 3g over a predetermined length, are circumferentially separated at an upper end of the inner peripheral surface. Distal ends 3r (stepped surfaces) constituting the grooves 3n are stepped surfaces corresponding to the forward limit of the tubular element 4. The guide tube 3 with this structure is constituted in the following manner, as shown in FIG. The insertion part is inserted inside from the front side of the container main body 1. The flange portion 3x abuts against the upper end surface of the container main body 1.
    [0012] The concavo-convex portion 3d engages the concavoconvex portion la of the main container body 1 in the axial direction. Thus, the guide tube 3 is rotatably mounted relative to the main container body 1 and stationary in the axial direction. As shown in Fig. 19, the pawl spring member 7 has an approximately cylindrical shape. The intermediate portion connecting a ratchet portion 7a on the distal end side and a rear portion 7b is a spring-loaded resilient portion 7c. Here, the spring portion 7c is a resin spring integrally molded with the ratchet portion 7a and the rear end portion 7b and is formed approximately into a spiral shape.
    [0013] On the upper end surface of the ratchet portion 7a, a plurality of ratchet teeth 7x are circumferentially disposed next to one another. The ratchet teeth 7x engage the thread element 5 by ratchet.
    [0014] On the outer peripheral surface of the ratchet portion 7a, a plurality of projections 7d (here eight protrusions) extending in the axial direction are arranged homogeneously circumferentially adjacent to one another. The projections 7d cooperate with the grooves 1c of the main container body 1 in the direction of rotation. On the outer peripheral surface of the rear portion 7b also, a plurality of protrusions 7e (here four protrusions) extending in the axial direction are arranged homogeneously circumferentially adjacent each other. The projections 7e cooperate with the grooves 1c of the main container body 1 in the direction of rotation. The projections 7e of the rear portion 7b are disposed on the extended line of the projections 7d of the ratchet portion 7a. The ratchet spring element 7 having this configuration, as shown in FIG. 3, is inserted inside from the front side of the container main body 1. The rear end surface of the spring element of the pawl 7 abuts against the upper end surfaces 1b of the projections 1f of the main container body 1. The projections 7a of the ratchet portion 7a and the projections 7e of the rear portion 7b cooperate with the grooves 1c of the main body. containing 1 in the direction of rotation. Thus, the ratchet spring member 7 is mounted to rotate synchronously with the container main body 1, the spring portion 7c is axially extensible and the ratchet portion 7a is mounted moving way in the axial direction.
    [0015] As shown in FIGS. 16 to 18, the threaded member 5 has an approximately cylindrical shape. The threaded member 5 has a male thread (a spiral protrusion) 5e as the first male thread. The male thread 5e is disposed in the middle of the peripheral surface in the axial direction. The male thread 5e constitutes the other element of the first threaded part 8 and cooperates with the female thread 5i of the guide tube 3. On the inner peripheral surface, a female thread 5j constituting an element of the second threaded part 9 is disposed on the front side of the threaded member 5. The female thread 5j is disposed as a second thread on a predetermined interval along the axial direction. The rear end portion of the threaded member 5 is a widened diameter portion 5c. The diameter forward with respect to the rear end portion is enlarged. A plurality of ratchet teeth 5x are circumferentially disposed adjacent one another on a rear end surface of this enlarged diameter portion 5c. The ratchet teeth 5x agree circumferentially with the ratchet teeth 7x of the ratchet spring member 7. One of these ratchet teeth of the ratchet teeth 7x and 5x allows rotation of the other ratchet teeth in one direction. only. Here, the rotation of one of the ratchet teeth in the feed direction (i.e., the direction of travel) is permitted while the rotation of one of the ratchet teeth in the return direction (c). that is, retraction) is not allowed. At the tip end of the threaded element 5, a pair of small windows 5a is opened in opposite position. The small windows 5a communicate between the inside and the outside. On the inner peripheral surface on the front side of these small windows 5a, convex locking portions 5b extend in the axial direction. The convex locking portions 5b engage the tubular member 4 in the axial direction. The threaded member 5 having this configuration, as shown in FIG. 3, is inserted inside from the front side of the container main body 1. The upper end surface of the enlarged diameter portion 5c is abutting on the rear end portion of the guide tube 3 and is pushed. This aligns the ratchet teeth 5x with the ratchet teeth 7x of the ratchet spring member 7. This compresses the spring portion 7c of the ratchet spring member 7. Then, the male thread 5e is screwed onto the female thread 3i of the guide tube 3, thus constituting the first threaded portion 8. The contact of the upper end surface of the enlarged diameter portion 5c with the rear end portion of the guide tube 3 may correspond to the forward limit of the threaded element 5 (tubular element 4). The movable body 6 includes the 6x piston at the distal end and a shaft portion 6y. The rod portion 6y is located at the rear end of the piston 6x and extends in the axial direction. The shank portion 6y has a pressure portion 6a at the tip end. The pressure portion 6a enters a concave portion 6z which is recessed at the rear end of the piston 6x to advance the piston 6x. As shown in Fig. 20, the shank portion 6y comprises a male thread 6b (spiral projection) as the second male thread. The male thread 6b is disposed from the rear end to the middle of the pressing portion 6a in the axial direction on the outer peripheral surface. The male thread 6b constitutes the other element of the second threaded portion 9. The male thread 6b is screwed onto the female thread 5j of the threaded element 5. On the rear end portion of the movable body 6, portions convex 6c are arranged. The convex portions 6c extend in a transverse direction as seen from the axial direction. The convex portions 6c cooperate with the projections 1f of the container main body 1 in the direction of rotation.
    [0016] As shown in FIGS. 2 and 3, the movable body 6 having such a configuration is inserted inside the container main body 1, the ratchet spring element 7 and the thread member 5. As shown in Fig. 12, the respective convex portions 6c at the rear end portion of the movable body 6 engage between the projections 1f and 1f of the container main body 1. This results in mounting of the movable body 6 so as to be in position. rotation synchronously to the main container body 1 and movable in the axial direction. As shown in FIG. 3, the male thread 6b is screwed onto the female thread 5j of the threaded element 5 thus constituting the second threaded part 9. With regard to this second threaded part 9 and the first threaded part 8 described above, the thread pitch of the first threaded portion 8 is greater compared to the thread pitch of the second threaded portion 9.
    [0017] As shown in FIG. 3, the tubular element 4 has an approximately cylindrical shape. The cosmetic material M having the shape of a stick is introduced into the tube hole. The cosmetic material M having the shape of a stick is housed almost entirely in the tubular element 4 so as to be sliding. As shown in Figures 21 and 22, at the rear end portion of the tubular member 4, a convex annular portion 4a is disposed. The convex portion 4a cooperates with the convex locking portions 5b in front of the small windows 5a of the threaded member 5 in the axial direction. On the outer peripheral surface at the front portion with respect to the convex portion 4a of the tubular member 4, a groove 4b is disposed. When the tubular element 4 moves, an annular seal 11 is advanced towards the groove 4b. The annular seal 11 is disposed on the inner peripheral surface of the guide tube 3 for proper sliding. Between the convex annular front and rear portions 4c and 4d forming the groove 4b, the convex portion 4d of the rear side is abutted against the upper end surface of the thread member 5. The convex portion 4d takes the tip end the threaded member 5 sandwiched with the convex portion 4a which is near the rear end portion in the axial direction. At the convex portion 4c, which is located on the front side on the outer peripheral surface of the tubular member 4, a plurality of projections 4e (here four projections) are arranged homogeneously circumferentially adjacent each other. The projections 4e extend forward from the front side surface of the convex portion 4c for a predetermined length. The projections 4e engage in the grooves 3h of the guide tube 3 to engage the grooves 3h in the direction of rotation.
    [0018] A plurality of projections 4n (here four projections) are homogeneously disposed circumferentially at the distal end of the tubular member 4. The projections 4n extend forwardly in the axial direction and engage in the grooves 3n. 3. In a corresponding manner, the convex portion 3p of the guide tube 3 engages in the grooves 4p between the projections 4n and 4n which are circumferentially disposed on the tubular member 4. The projections 4n are formed extending the distal end of the tubular member 4 forwardly. Correspondingly, the inner diameters of the projections 4n and an inner diameter of a portion at the rear of these projections 4n have identical diameters allowing the cosmetic material M in the shape of a stick to slide. The inner diameters of the projections 4n and the inside diameter of the convex portion 3p described above of the guide tube 3 are also identical diameters.
    [0019] As shown in FIGS. 23-25, the rear end portion of the tubular member 4 thus configured is inserted within the tip end of the thread member 5. The back end surface of the convex portion 4d of the rear side of the tubular member 4 abuts against the upper end surface of the thread member 5. The convex portions 4a engage the small windows 5a of the thread member 5 to engage the convex locking portions 5b in the axial direction (see Fig. 24). In addition, the tip end of the threaded member 5 is sandwiched between the convex portions 4a and the convex portions 4d. Thus, the tubular element 4 and the threaded element 5 are fixedly mounted in the axial direction.
    [0020] The tubular element 4 connected to the threaded element 5 is inserted, as shown in FIG. 3, inside from the rear side of the tube hole 3g of the guide tube 3. The projections 4e engage in the grooves 3h of the guide tube 3 to engage the grooves 3h in the direction of rotation. Thus, the tubular member 4 is non-rotatably mounted in the guide tube 3 and movable in the axial direction. In this state, as shown in FIGS. 5, 10 and 11, the projections 4n on the side of the distal end of the tubular element 4 engage in the grooves 3n of the guide tube 3. The convex portions 3p 10 of the 3 guide tube are also in the state to engage in 4p grooves. A distal end 4r of the projection 4n of the tubular member 4 moves (advance or retract) into the groove portion G as described above. As shown in FIG. 3, the piston 6x at the distal end of the movable body 6 enters the rear end of the tube of the tubular member 4 by being pressed by the pressing portion 6a. As shown in FIG. 3, in the initial state, the threaded member 5 reaches a threading front limit through the first threaded portion 8, and the tubular member 4 is positioned at the forward limit. More particularly, with the tubular element 4, as shown in FIG. 5, the distal end 4r of the projection 4n at the distal end of the tubular element 4 abuts against the distal end 3r of the groove 3n of the guide tube 3. As the position of the forward limit for the tubular element 4, a position where the distal end of the projection 4e on the side of the rear end of the tubular element 4 abuts against the distal end 3j of the groove 3h of the guide tube 3, or a position where a rear end 4s of the groove 4p of the tubular element 4 abuts against a rear end 3s of the convex part 3p 35 of the tube guide 3 can be used. In this state, in the portion G forming grooves, the projection 4n of the tubular element 4 and the groove 3n of the guide tube 3, and the groove 4p of the tubular element 4 and the convex portion 3p of the guide tube 3 are in direct contact without gaps. The projection 4n of the tubular element 4 and the convex portion 3p of the guide tube 3 form a flat surface without staging, a surface where the cosmetic material M having the shape of a stick can slide smoothly. As shown in FIG. 3, the rear end surface of the piston 6x of the movable body 6 is disposed in the tubular element 4 so as to form a planar surface with the rear end surface of the tubular element 4. this state, the cosmetic material M having the shape of a stick is housed so that the upper end surface is flush with an opening 3t (distal end of the tube hole 3f for the cosmetic material having the shape of a stick) at the distal end of the guide tube 3. The cosmetic material M having the shape of a stick is introduced into the container according to the following method. More particularly, when the cosmetic material feed container 100 in the form of a stick is in the initial state, a molten cosmetic material is injected into the container through the opening 3t at the distal end of the guide tube. 3 to fill it with the melted cosmetic material until the opening 3t. At this moment, as described above, in the portion G forming grooves, the projection 4n of the tubular element 4 and the groove 3n of the guide tube 3, and the groove 4p of the tubular element 4 and the convex portion 3p of the guide tube 3 are in direct contact without deviation. Correspondingly, the inner peripheral surface of the tube is without gap; for this reason, the melted cosmetic material is precisely filled in the tube.
    [0021] When the cosmetic material is cooled and hardened, the cosmetic material M is in the tubular element 4 and in the tube hole 3f for cosmetic material in the form of a stick, the guide tube 3 whose rear ends are covered by the piston 6x. According to an alternative method, the cosmetic material M already having the shape of a stick is introduced by insertion through the opening 3t at the distal end of the guide tube 3.
    [0022] The user purchases the cosmetic material feed container in the shape of a stick in the configuration of the cosmetic material supply container 100 described above in the initial state shown in FIGS. 2 and 3.
    [0023] In this state, as represented in FIGS. 3 to 5, the cosmetic material M having the shape of a stick is held on the complete periphery by the inner peripheral surface of the tubular element 4 on a part behind the projection 4n. of the tubular element 4. At the tube hole 3f for a cosmetic material having the shape of a stick, the cosmetic material M having the shape of a stick is held on the entire periphery by the inner peripheral surface of the tube hole 3f . In the groove portion G, the stick-shaped cosmetic material M is held around the entire circumference by the inner peripheral surface formed by the projections 4n of the tubular element 4 and the grooves 3n of the guide tube 3. in direct contact without gap. Thus, the cosmetic material M having the shape of a stick is protected. When the user rotates the main container body 1 and the guide tube 3 in the feeding direction, for example when the user grasps the guide tube 3 and turns the main container body 1, the main container body 1, the movable body 6 and the pawl spring element 7 rotate at the same time.
    [0024] At this time, by the prestressing force of the spring portion 7c of the pawl spring member 7, the pawl teeth 5x and 7x engage. However, the threaded member 5 is located at the forward limit through the first threaded portion 8 and, therefore, further advancement is prevented. Correspondingly, if the user continues the rotation operation in the feed direction, while the rotation of the thread member 5 in the feeding direction is blocked, the ratchet teeth 7x of the element with a ratchet spring 7 which rotate synchronously with the main container body 1, move freely relative to the ratchet teeth 5x of the thread member 5. Together with this free movement, a click sound and a clicking sensation are generated. At the same time with this, the movable body 6, which rotates synchronously with the main container body 1, rotates in the feed direction.
    [0025] Between the movable body 6 and the threaded member 5 which stops rotating, the screwing action by the second threaded portion 9 is activated. As shown in FIGS. 6 to 8, the moving body 6 advances and the piston 6x pulls out the cosmetic material M having the shape of a stick in the tubular element 4 (see FIG. 6). Here, compared to the screw pitch of the first threaded portion 8, the thread pitch of the second threaded portion 9 is small. As a result, the movable body is slowly advanced along the small thread of the second threaded portion 9, and the stick-shaped cosmetic material M is suitably pulled out of the tubular member 4. Thus, the cosmetic material M having the shape of a stick appears at the opening 3t of the guide tube 3 ready for use. During the rotation operation to release the cosmetic material M having the shape of a stick, the noise and the clacking sensation described above are generated for the user. This preferably makes it possible to feed the cosmetic material M having the shape of a stick, ensuring the use. After the application, when the user rotates the container main body 1 and the guide tube 3 in the return direction, for example when the user grasps the guide tube 3 and rotates the container main body 1, the container main body 1, the movable body 6 and the ratchet spring portion 7 rotate synchronously. Here, as described above, the ratchet teeth 5x and 7x do not allow the rotation of a ratchet tooth in the return direction. As a result, the threaded member 5 and the pawl spring member 7 rotate together in the return direction. Thus, between the threaded portion 5 and the guide tube 3, the screwing action by the first threaded portion 8 is activated. As shown in FIGS. 9 to 11, the threaded member 5 retracts together with the tubular member 4. The user continues the rotation operation until a distal end of the cosmetic material M having the The shape of a stick descends from the opening 3t of the guide tube 3 (see FIG. 9). Here, compared with the thread pitch of the second threaded portion 9, the thread pitch of the first threaded portion 8 is large. For this reason, thanks to the large thread of the first threaded part 8, the threaded element 5 and the tubular element 4 are quickly retracted. In this state, the tubular member 4 retracts from the advancing limit and the stick-shaped cosmetic material M extends forwardly from the distal end 4r of the projection 4n of the tubular element 4 (see Figure 9). In this state, as shown in FIGS. 10 and 11, when the stick-shaped cosmetic material M is in a position farther back than the groove-forming portion G and the projections 4n are in arranged positions. next to one another circumferentially, the cosmetic material M having the shape of a stick is held around the periphery of the plurality of portions by the inner surfaces of the projections 4n of the tubular element 4. To the tube hole 3f for the cosmetic material M having the shape of a stick, the cosmetic material M having the shape of a stick is held on the entire periphery by the inner peripheral surface of the tube hole 3f for the cosmetic material having the shape of a stick. In the groove section G, at the tip ends of the projections 4n and in the gap where the tip ends of these projections are adjacent to the rear end portions of the convex portions 3p of the guide tube 3 and wherefore for this reason the tip ends and the rear end portions overlap circumferentially, the stick-shaped cosmetic material M is held around the entire periphery by the inner peripheral surfaces of the convex portions 3p. In the groove portion G, at the front portion with respect to the overlapping circumferential gap, the stick-shaped cosmetic material M is held circumferentially on the plurality of portions by the inner surfaces of the convex portions. 3p of the guide tube 3. Thus, the cosmetic material M having the shape of a stick is protected. As described above, this protection configuration is identical until the threaded element 5 and the tubular element 4 reach the advancing limit. When the distal end of the cosmetic material M having the shape of a stick is lowered from the opening 3t of the guide tube 3, and when the user continues the rotation operation, the screwing action by the first part 8 further retracts the thread member 5, and the rear end of the female thread 3i of the guide tube 3, the distal end of the male thread 5e of the thread member 5 is disengaged, which corresponds to in a relaxed state. However, the threaded member 5 is preloaded forward by the spring portion 7c of the pawl spring portion 7. For this, the distal end of the male thread 5e of the thread member 5 is pressed toward the rear end of the female thread 3i of the guide tube 3, and the threaded member 5 immediately returns to the screwed state. Then, when the user turns the container main body 1 and the guide tube relatively in the feeding direction, for example when the user grasps the guide tube 3 and turns the container main body 1, the 5x and 7x pawl strongly engage the prestressing force by the spring portion 7c of the pawl spring element 7. Since the threaded member 5 and the pawl spring member 7 can rotate synchronously , the main container body 1 and the movable body 6 rotate synchronously with the threaded element 5 and the pawl spring element 7. This activates the screwing action by the first threaded part 8. The threaded member 5 advances together with the tubular member 4 and the movable body 6. When the thread member 5 reaches the forward limit, further advancement of the thread member 5 is blocked and the screwing action by the first part to fi lets 8 stops. At this moment, in the case where the tip end of the cosmetic material M having the shape of a stick extends from the opening 3t of the guide tube 3 over a desired distance, the cosmetic material M having the shape a stick is arranged for an application in this state. By cons, when the tip end of the cosmetic material M having the shape of a stick does not extend from the opening 3t of the guide tube 3, for a desired distance, the user turns the main body of container 1 and the guide tube 3 further in the feed direction. Thus, analogously to the configuration described above, the screwing action by the second threaded portion 9 is activated to advance the movable body 6. Then, the cosmetic material M having the shape of a stick is released on a desired distance, ensuring the supply of the cosmetic material M having the shape of a stick for application. Correspondingly, the present embodiment is configured as follows. At the distal end of the tubular member 4, the plurality of projections 4n are circumferentially disposed. The projections 4n extend forward in the axial direction. At the tip end of the guide tube 3 is disposed the groove portion G. The groove portion G comprises the plurality of grooves 3n circumferentially in the inner peripheral surface. The grooves 3n extend in the axial direction. The projections 4n engage in the grooves 3n.
    [0026] On the guide tube 3, the inside diameter of the convex part 3p between the circumferentially disposed grooves 3n and 3n and the inside diameter of the tubular part which houses the projections 4n of the tubular element 4 and the cosmetic material M having The shape of a stick back to the projection 4n have identical dimensions. A configuration where an advance or retraction of the tubular member 4 moves the distal ends 4r of the projections 4n of the tubular member 4 into the groove portion G forming the guide tube 3 is applied. Even if the distal ends 4r of the projections 4n of the tubular element 4 retract back relative to the distal ends 3r of the grooves 3n of the guide tube 3 (even if the distal ends 3r retract more than the forward limit) this configuration holds the cosmetic material M in the shape of a stick and extending from the projections 4n of the tubular element 4, circumferentially on a plurality of portions by inner surfaces of the convex portions 3p between the grooves 3n and 3n in the portion G forming grooves of the guide tube 3. Therefore, even if the cosmetic material supply container 100 M having the shape of a stick is subjected to impacts or vibrations, a breakage of M cosmetic material having the shape of a stick can be prevented. Although the present invention has been described more particularly on the basis of the embodiment, the invention is not limited to this embodiment and its variants mentioned. For example, the embodiment and its variants describe the application to a stick-shaped cosmetic material supply container 100, which uses the stick-shaped cosmetic material M as a particularly preferred embodiment. preferable. However, it is obvious that the present invention is also applicable to a material feed container in the shape of a stick such as a writing material where, for example, a graphite lead is used as a material having the shape of a stick.
