BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a container for feeding a stick type cosmetic material, such as an eyebrow pencil, an eyeliner, a lip liner, and the like. It particularly relates to a method for loading a core material in the container. 
   2. Description of the Related Art 
     FIGS. 12 and 13  show a method for loading a stick type cosmetic material whose core has a thin diameter, such as a conventional eyebrow pencil and the like, in a stick type cosmetic 
   Stick type cosmetic materials have diameters that vary in size from a material having a large diameter to a material having a small diameter, such as a lipstick, an eyebrow pencil, an eyeliner, and the like. Manufacturing methods of such stick type cosmetic materials are roughly divided into molding of a core by die and extrusion of a core by machine. 
   A core used for a stick type cosmetic material in a free form, such as a lipstick, is manufactured mainly by molding. With respect to a core having a small diameter, such as an eyebrow pencil and the like, there are many cases in which a core material is extruded with a uniform diameter, cut and then used. material retaining section  331  formed at a front end of a core chuck member  330  which vertically travels in a front cylinder  310 . 
   Usually the stick type cosmetic material retaining section  331  is in the shape of a cup as shown in the drawings and it is arranged such that the stick type cosmetic material is forced to fit in a cavity section which is bored in this cup section. 
   Therefore, in many cases, some vertical ribs are formed on an inner circumferential surface of the cup section and because the vertical ribs cut into a part of the stick type cosmetic material when the stick type cosmetic material is inserted, engagement force is increased or the stick type cosmetic material is forced to fit in the cup in which no ribs are formed with an outer circumferential surface of the stick type cosmetic material being slightly scraped. 
     FIG. 12  shows a state in which the core chuck member  330  is fed up to the advance limit in order for a core material having a thin diameter, such as an eyebrow pencil or the like, to fit in the stick type cosmetic material retaining section  331 . A stick type cosmetic material D is forced to fit in the stick cosmetic material retaining section  331  through a front end opening hole by a skillful operator in such a state that the core chuck member  330  is fed up to the advance limit. 
   Feeling the resistance at the time of loading the stick type cosmetic material, the operator securely fits the stick type cosmetic material D in the stick type cosmetic material retaining section  331 . The operator then feeds down the core chuck member  330  to the retreat limit as shown in  FIG. 13 , whereby a loading operation is completed. 
   The reason why the core material is loaded after the core chuck member  330  is fed up to the advance limit is as follows. As shown in  FIG. 13 , due to a thickness X of the circumference of the cosmetic material retaining section  331 , there is a gap between an outer circumference of the stick type cosmetic material D and a through hole  313  in which the core chuck member  330  slides. If the stick type cosmetic material retaining section  331  is far away from a front end opening hole  311 , it will not be easy to put the stick type cosmetic material D, which has been inserted through the front end opening hole  311 , in a cavity section of the stick type cosmetic material retaining section  331 . Therefore, operations will not be easy unless the front end opening hole  311  is kept close to the stick type cosmetic material retaining section  331  by feeding up the core chuck member  330  up to the advance limit. 
   SUMMARY OF THE INVENTION 
   An advantage of the present invention is to provide a stick type cosmetic material container which is capable of securely retaining a stick type cosmetic material with strong retaining force without letting a part of the stick type cosmetic material cut in a stick type cosmetic material retaining section or without scraping the stick type cosmetic material when the stick type cosmetic material is loaded. 
   A further advantage of the present invention is to provide a stick type cosmetic material container which does not require a special skill in loading work for the stick type cosmetic material and is capable of enhancing an efficiency of the loading work. 
   Therefore, the present invention is a stick type cosmetic material feeding container which has a front cylinder and a base body rotatably connected with the front cylinder and in which due to relative rotations of the front cylinder and the base body, a stick type cosmetic material retained by a core chuck member slides forward and backward along a through hole which extends in an axial direction in the front cylinder. 
   The stick type cosmetic material feeding container comprises: a plurality of first slide grooves formed along an inner circumference of a through hole having an inside diameter which is almost equal to an outside diameter of the stick type cosmetic material, the first slide grooves extending in an axial direction; a plurality of second slide grooves which are located at ends of the first slide grooves, formed continuously from the ends, and deeper than the first slide grooves; and a plurality of claws which are formed at a front end section of the core chuck member so as to retain the stick type cosmetic material and slidably guided by the first slide grooves and the second slide grooves, the back surfaces of which slide and come into contact with bottoms of the first slide grooves, and the inner surfaces of which almost coincide with an inside diameter of the through hole. 
   If the stick type cosmetic material is loaded in the core chuck member when the claws are located at the second slide grooves, the claws will elastically be deformed in the direction of an outer circumference and the stick type cosmetic material will be received inside the claws. When the claws are located at the first slide grooves, the claws retain the stick type cosmetic material by tightly sandwiching the stick type cosmetic material with pressure from the outer circumference side.

   DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Embodiments of the present invention will be described in detail with reference to the accompanying drawings. 
   In  FIG. 1 , a stick type cosmetic material feeding container  1  has a front cylinder  10  and a base body  20 , and a base end of the front cylinder  10  is coaxially fitted in the base body  20 , whereby the front cylinder  10  and the base cylinder  20  can mutually rotate. A core chuck member  30  which retains a stick type cosmetic material A and shifts in an axial direction is housed inside the front cylinder  10 . A feeding mechanism for shifting the core chuck member  30  by operation of the mutual rotations of the front cylinder  10  and the base body  20  which will be described later is installed in the front cylinder  10  and the base body  20 . 
   A through hole  13  which is continued from a front end opening hole  11  and extends in an axial direction is bored in the shaft center of the front cylinder  10 . The through hole  13  is formed so that its inside diameter is slightly smaller than an outside diameter of the stick type cosmetic material A. 
   Four slide grooves  12  are provided in an axial direction along the through hole  13  in such a manner that the slide grooves  12  surround the through hole  13 . As shown in  FIG. 2 , the slide grooves  12  are provided as first slide grooves  12   a  on the side of the front end opening hole  11  and continued from the ends of the first slide grooves  12   a  through a taper surface  14   c  as second slide grooves  12   b.    
     FIG. 3  clearly shows shapes of the first slide grooves  12   a  and the second slide grooves  12   b.  The first slide grooves  12   a  and the second slide grooves  12   b  are formed in such a manner that these groove widths are identical, but these groove depths are different. Bottom surfaces  14   b  of the second slide grooves  12   b  are deeper than bottom surfaces  14   a  of the first slide grooves  12   a.  These bottom surfaces  14   a  and  14   b  whose depths differ are connected by the taper surface  14   c  whose depth gradually varies. 
   A plurality of claws, namely four claws  32  in this embodiment, which slide under the guidance of these slide grooves  12  are provided at a front end section of the core chuck member  30 . These claws  32  constitute a stick type cosmetic material retaining section  31 . A base end of each of the claws  32  is connected with the core chuck member  30  and a front end of each of the claws  32  is formed as a free end. 
   These claws  32  retain the stick type cosmetic material A by the mutual inner circumferential surfaces in such a manner that the claws  32  sandwich the stick type cosmetic material A with pressure from its outer circumference. Thus, an inside diameter surface of each of the claws  32  forms a part of a circumference and its inside diameter is slightly smaller than an outside diameter of the stick type cosmetic material A. 
   A projection  33  is provided as a contact section on a back surface of each of the claws  32 . The projections  33  slide and come into contact with the bottom surfaces  14   a  of the first slide grooves  12   a,  but it is arranged such that the projections  33  do not come into contact with the bottom surfaces  14   b  of the second slide grooves  12   b  which are deeper than the first slide grooves  12   a.    
   In  FIG. 1 , the claws  32  formed at a front end of the core chuck member  30  are located at the second slide grooves  12   b.  Because the projections  33  of back surfaces of the claws  32  at this position are not in contact with the bottom surfaces  14   b  of the second slide grooves  12   b,  the claws  32  can elastically be deformed outward in a direction of enlarging the inside diameter of the claws  32 . Therefore, at this position, the stick type cosmetic material A inserted through the front end opening hole  11  of the front cylinder  10  reaches a bottom surface  31   a  of the stick type cosmetic material retaining section  31  without meeting with any resistance. 
   As shown in  FIG. 4 , the core chuck member  30  shifts in an axial direction toward the side of the front end opening hole  11  of the front cylinder  10  from this state. When the claws  32  enter into the first slide grooves  12   a,  the projections  33  provided on the back surfaces of the claws  32  come into contact with the bottom surfaces  14   a  of the first slide grooves  12   a  and the claws  32  sandwich the stick type cosmetic material A with pressure from four directions to the inside. Thus, the stick type cosmetic material A is securely retained. 
   Even in this case, however, the claws  32  come into contact with the bottom surfaces  14   a  of the first slide grooves  12   a  through the projections with a small area. Therefore, resistance is not large when the core chuck member  30  shifts along the slide grooves  12 , so that the core chuck member  30  can smoothly slide. 
   Therefore, in the present invention, the core chuck member  30  is mostly retracted in advance and the stick type cosmetic material A is inserted through the front end opening hole  11  until the stick type cosmetic material A comes into contact with the core chuck member  30 . The core chuck member  30  is then slightly moved in the axial direction toward the side of the front end opening hole  11  and therefore the stick type cosmetic material A can securely be retained. Further, because the stick type cosmetic material A is retained in such a manner that the stick type cosmetic material A is not deformed and scraped, but wrapped, it is possible to retain the stick type cosmetic material A strongly and securely. 
   Next, a feeding mechanism of the core chuck member  30  of the stick type cosmetic material feeding container  1  shown in  FIG. 1  will be described. 
   The core chuck member  30  has the claws  32  to be guided by the slide grooves  12  and also linear projections  35  which extend continuously from the claws  32  down the stick type cosmetic material retaining section  31  are formed. The linear projections  35  are slidably engaged with the slide grooves  12  and therefore the core chuck member  30  and the front cylinder  10  are united, thereby constituting a rotation regulating mechanism. 
   The linear projections  35  are formed at an outer circumference of a shaft  34  of the core chuck member  30 , and a cylindrical body  36  which has a diameter larger than that of the shaft  34  is installed at a rear part of the core chuck member  30 . 
   The base body  20  is connected with the front cylinder  10  and also an inner hole extending in an axial direction is formed inside the base body  20 . A roulette-shaped spiral  22  is formed at the inner hole. 
   A plurality of engagement projections  39  are arranged at the cylindrical body  36  which is formed at a rear part of the core chuck member  30 , and the engagement projections  39  are elastically and spirally engaged with the roulette-shaped spiral  22  in the base body  20 , thereby constituting a spiral engagement mechanism. 
   More specifically, when the front cylinder  10  is rotated relatively to the base body  20 , the core chuck member  30  rotates in one united body with the front cylinder  10  due to the rotation regulating mechanism. Because the engagement projections  39  are spirally engaged with the roulette-shaped spiral  22  of the base body  20 , the core chuck member  30  shifts in an axial direction. 
   Further, it is arranged such that an outside diameter of the cylindrical body  36  is in contact with an inside diameter of the roulette-shaped spiral  22  of the base body  20 . When the core chuck member  30  is retracted most, a rear end surface of the core chuck member  30  comes into contact with a stepped section  23  which is provided at a rear part of the base body  20 , thereby defining the retreat limit. 
   In this state, the claws  32  of the stick type cosmetic material retaining section  31  are located at the second slide grooves  12   b  and the stick type cosmetic material A can be loaded as described above. 
   Further, a tail plug  40  is inserted through an opening hole  29  of the base body  20  into a small diameter section  28  which is formed in the rear of the stepped section  23 . The retreat limit of the core chuck member  30  is defined by bringing a front end section  44  of the tail plug  40  into contact with a rear end surface of the cylindrical body  36  of the core chuck member  30 , so that the tail plug  40  acts as a regulating means for defining a retreat position of the core chuck member  30 . 
   In this state, the claws  32  of the core chuck member  30  are located at the first slide grooves  12   a  and cannot enter into the second slide grooves  12   b.  Thus, by installing the tail plug  40  at the base body  20  after the stick type cosmetic material A is installed at the core chuck member  30  as described above, the claws  32  can shift in an axial direction by a scope of the first slide grooves  12   a.  Therefore, the claws  32  cannot be deformed in such a manner that an inside diameter of the claws  32  expands toward the outer circumference, and the stick type cosmetic material A can securely be retained by the claws  32 . 
   A pair of slits  43  are provided at the tail plug  40  and a first projection  41  is provided between these slits  43 . The first projection  41  fits in a tail plug fit-in groove  27  which is provided at the base body  20  and therefore the tail plug  40  is securely engaged with the base body  20  so that the tail plug  40  will not fall out. 
   Initially, the tail plug  40  is not installed in the stick type cosmetic material feeding container  1 , and the core chuck member  30  is shifted to the retreat limit. In this state, as described above, when the stick type cosmetic material A is loaded, the stick type cosmetic material A reaches the bottom surface  31   a  of the stick type cosmetic material retaining section  31  without meeting with any resistance. 
   In this state, when a bottom surface of a flange  45  of the tail plug  40  is pressed until a second projection  42  fits in the tail plug fit-in groove  27 , the core chuck member  30  pressed by the tail plug  40  shifts in an axial direction by length Y when the tail plug  40  is pressed. Thus, the claws  32  of the core chuck member  30  slide on the taper surface  14   c  from the second slide grooves  12   b  and shift to the first slide grooves  12   a.  Thus, the stick type cosmetic material A is securely retained by the four pieces of claws  32  without being scraped or deformed. This position is the feeding retreat limit of the stick type cosmetic material feeding container  1  in a normal working condition. 
   The flange  45  of the tail plug  40  is adjusted to the color of the stick type cosmetic material A to be loaded and also a discriminating criterion is manifest such that when the tail plug  40  is exposed from the front cylinder  10  as shown in  FIG. 1 , the stick type cosmetic material A has not been loaded and when the tail plug  40  is completely pushed in as shown in  FIG. 4 , the stick type cosmetic material A has been loaded and the stick type cosmetic material feeding container  1  is a finished body. Thus, the stick type cosmetic material feeding container  1  is characterized in that it is easy to handle. 
   When the front cylinder  10  and the base body  20  are relatively rotated in such a state, a feeding mechanism operates due to both the rotation regulating mechanism, which is constituted by the slide grooves  12  in the front cylinder  10  and the linear projections  35  of the core chuck member  30 , and the spiral engagement mechanism, which is constituted by the engagement projections  39  provided at an outer circumference of the cylindrical body  36  of the core chuck member  30  and the roulette-shaped spiral  22  provided in the base body  20 . When the core chuck member  30  shifts in an axial direction in the front cylinder  10  in one body with the front cylinder  10 , a front end of the stick type cosmetic material A retained by the claws  32  is fed out of the opening hole  11 . It is possible to put on makeup in this state. 
     FIGS. 7 and 8  show a second embodiment of the present invention. 
   A stick type cosmetic material feeding container  101  comprises four members, such as a front cylinder  110 , a base body  120 , a core chuck member  130 , and a spiral engagement member  150  which is connected with the core chuck member  130  and constitutes a part of a spiral engagement mechanism. 
   The front cylinder  110  has an opening hole  111  at its front end, and a through hole  113  which is bored and has a diameter almost the same as that of the opening hole  111  is provided. Similarly to the first embodiment, four slide grooves  112  are arranged along the through hole  113 . 
   These slide grooves  112  comprise first slide grooves  112   a  provided at the front part and second slide grooves  112   b  which are provided at the rear part and whose groove depth is deeper than that of the first slide grooves  112   a.  A bottom surface  114   a  of each of the first slide grooves  112   a  is connected with a bottom surface  114   b  of each of the second slide grooves  112   b  via a taper surface  114   c.    
   As shown in  FIG. 7 , when a stick type cosmetic material B is inserted through the opening hole  111  of the front cylinder  110 , claws  132  of the core chuck member  130  are caused to locate at the second slide grooves  112   b  and an end surface of the stick type cosmetic material B is caused to come into contact with a bottom surface  131   a  of a stick type cosmetic material retaining section  131  of the core chuck member  130 . However, because the claws  132  are expanded, the stick type cosmetic material B is not retained tightly with pressure. 
   This is because the bottom surfaces  114   b  of the second slide grooves  112   b  are deep and projections  133  of the claws  132  are not in contact with the bottom surfaces  114   b.    
   A first cavity section  110   c  having a large diameter and a second cavity section  110   d  whose diameter is smaller than that of the first cavity section  110   c  are formed at the rear parts of the front cylinder  110  coaxially with the through hole  113 . A fit-in convex section  117   b  is provided on an inner surface of the first cavity section  110   c  and rotatably engaged with a front part annular concave section  121   b  which is formed at an outer circumference of a front part of the base body  120 . 
   The fit-in convex sections  117   b  are formed at three positions of an inner circumferential end surface of the first cavity section  110   c  of the front cylinder  110 . 
   As described above, in a state in which the front end annular concave section  121   b  is engaged with the fit-in convex section  117   b,  a space equivalent to the length Y is left between a rear end section  116  of the front cylinder  110  and an end surface  125  of the base body  120 . 
   When the front cylinder  110  is pressed toward the base body  120  after the stick type cosmetic material B is inserted through the front end opening hole  111  of the front cylinder  110  up to the bottom surface  131   a  of the stick type cosmetic material retaining section  131  of the core chuck member  130 , the four claws  132  which constitute the stick type cosmetic material retaining section  131  located at the retreat limit shift to the first slide grooves  112   a  from the second slide grooves  112   b  via the taper surfaces  114   c,  and the projections  133  on back surfaces of the claws  132  come into contact with the bottom surfaces  114   a  of the first slide grooves  112   a.  Thus, the claws  132  are pressed toward the inside diameter and it is possible to retain the stick type cosmetic material B by the claws  132  with fixed retaining force. 
   This position is a substantial feeding retreat limit of a stick type cosmetic material. 
   According to the first embodiment, the retreat limit is defined by shifting the core chuck member  30 , but according to the second embodiment, the position of the core chuck member  130  is not changed and the front cylinder  110  is in a condition to be shifted. 
   Thus, according to the second embodiment, it is determined such that feeding retreat limits of an empty container of FIG.  7  and the stick type cosmetic material feeding container  101  of  FIG. 8  in which the stick type cosmetic material B is loaded are at the same position. 
   Further, when the front cylinder  110  is pressed toward the base body  120 , the fit-in convex section  117   b  which has fitted in the front part annular concave section  121   b  of the base body  120  comes off. The fit-in convex section  117   b  then fits in a rear part annular concave section  121   b′  and also a fit-in concave section  117   a  provided at the second cavity section  110   d  of the front cylinder  110  is engaged with a fit-in convex section  121   a  of the base body  120 . Thus, the front cylinder  110  and the base body  120  are securely connected. 
   In a state of  FIG. 7  in which a space equivalent to the length Y is left between the front cylinder  110  and the base body  120  and then the stick type cosmetic material B is fully loaded in the front end opening hole  111 , the front cylinder  110  is pushed so as to eliminate a space equivalent to the length Y. Thus, the claws  132  are pushed up to the first slide grooves  112   a  and the stick type cosmetic material B is retained as shown in FIG.  8 . 
   Thus, the stick type cosmetic material B protrudes from the front end opening hole  111  of the front cylinder  110  by the length of Y, so that it is possible to cut the stick type cosmetic material B in normal length. 
   The stick type cosmetic material feeding container  101  becomes a finished body by shifting to a state shown in FIG.  8 . Due to rotary operation of the front cylinder  110  and the base body  120 , an engagement projection  151  provided at an outer circumferential wall  153  of the spiral engagement member  150  which is connected with a shaft  134  of the core chuck member  130  is spirally engaged with a roulette-shaped spiral  122  formed at an inside diameter of the base body  120 , thereby constituting a spiral engagement mechanism. Also, when convex sections  135  provided at lower parts of the claws  132  are engaged with the slide grooves  112  in the front cylinder  110 , a rotation regulating mechanism operates. Thus, the stick type cosmetic material B retained by the claws  132  of the core chuck member  130  advances and retreats through the opening hole  111  of the front cylinder  110  and it is possible to put on makeup. 
   The stick type cosmetic material feeding container  101  according to the second embodiment protects the feeding mechanism and the stick type cosmetic material B against a rotary load at the advance limit and the retreat limit due to a clutch rotation of the shaft  134  of the core chuck member  130  with respect to the spiral engagement member  150 . 
     FIGS. 9 ,  10 , and  11  show a third embodiment of the present invention. 
   The third embodiment represents a cartridge type stick-shaped cosmetic material feeding container  301 . FIG.  9 (A) is a partially longitudinal section showing a cartridge  301 C, and FIG.  9 (B) shows a holder  301 H to house the cartridge  301 .  FIG. 10  shows that the cartridge  301 C, in which a stick type cosmetic material C is loaded, is housed in the holder  301 H, in other words,  FIG. 10  shows the cartridge type stick-shaped cosmetic material feeding container  301 . 
     FIG. 11  shows each member of the cartridge  301 C. FIG.  11 (A) shows a front cylinder  210 , FIG.  11 (B) shows a base body  220 , and FIG.  11 (C) shows a core chuck member  230 . FIG.  11 (D) shows a stopper member  250  which fits in a concave section  238  provided at a rear part of the core chuck member  230  and defines a feeding stroke end of the core chuck member  230 . FIG.  11 (E) shows a tail plug  240  which fits in a tail plug fit-in section  227  of the base body  220 , and the tail plug  240  is formed by an elastic body, such as an elastomer. 
   The cartridge  301 C shown in FIG.  9 (A) will be described in detail with reference to each member which constitutes the cartridge  301 C of FIG.  11 . 
   A pinch section  210   a  to be used for rotations is provided at an outer circumference section of the front cylinder  210  and a base body fit-in cavity section  210   b  is provided at an inside diameter rear part of the front cylinder  210 . Further, the front cylinder  210  is rotatably connected with the base body  220  due to a fit-in concave section  217  provided at an inner circumference of a cavity section  201   b.    
   The base body  220  is formed in the shape of a cylinder and a spiral  222  is formed at an inside diameter of a front part. Also, an O-ring  3  is wound to an O-ring groove  220   b  provided at the outer circumference and the tail plug fit-in section  227  is provided at an inside diameter of the rear part. 
   With respect to the tail plug  240 , a first projection  241  fits in the tail plug fit-in section  227 . This shows a state of the cartridge  301 C of FIG.  9 (A). 
   In the third embodiment, a method for loading the stick type cosmetic material C in the cartridge  301 C is shown. FIG.  9 (A) shows a state where the stick type cosmetic material C is in contact with a bottom surface  231   a  of a stick type cosmetic material retaining section  231  constituted by claws  232  already formed at a front end of the core chuck member  230 . The state shows that the stick type cosmetic material C has not been retained by the claws  232  in such a manner that the claws  232  tightly sandwich the stick type cosmetic material C with pressure. 
   In  FIG. 11 , a through hole  213  having almost the same diameter as that of an opening hole  211  at a front end is bored in the front cylinder  210 . Four first slide grooves  212   a  are formed in an axial direction along the through hole  213  and connected with second slide grooves  212   b  through taper surfaces  214   c.    
   Four claws  232  are formed at a front end of the core chuck member  230 , and linear projection front end sections  235   a  are provided at base sections of the claws  232 . A lower end section of the core chuck member  230  is placed on a front end section  220   a  of the base body  220  and also back surfaces of the linear projection front end sections  235   a  are engaged with the second slide grooves  212   b,  thereby constituting a rotation regulating mechanism. 
   In FIG.  9 (A), when the claws  232  are located at the second slide grooves  212   b,  projections  233  provided at back surfaces of the claws  232  are not supposed to come into contact with bottom surfaces  214   b  of the second slide grooves. The stick type cosmetic material C inserted through the opening hole  211  of the front cylinder  210  reaches the bottom surface  231   a  of the stick type cosmetic material feeding section  231  without meeting with any resistance of the claws  232 . 
   A shaft  234  is formed at the core chuck member  230  and a linear projection  235  is arranged at an outer circumferential surface of the core chuck member  230 . A large number of engagement projections  239  are formed in line on a surface of the linear projection  235  and these engagement projections are male screws and are spirally engaged with the spiral  222  provided at a front part of the base body  220 , thereby constituting a spiral engagement mechanism. 
   Further, as shown in  FIG. 11 , a convex section  251  of the stopper member  250  fits in the concave section  238  provided at a rear part of the shaft  234 , and the front cylinder  210 , the base body  220 , the core chuck member  230 , the stopper member  250 , and the tail plug  240  constitute the cartridge  301 C. 
   In the state shown in FIG.  9 (A), a space equivalent to length Z is left between a flange  245  of the tail plug  240  and a rear end section  220 C of the base body  220 , and a front end section  240   a  of the tail plug  240  comes into contact with a rear end section  250   b  of the stopper member  250 . When the tail plug  240  is pushed in the base body  220 , the first projection  241  of the tail plug  240  which is engaged with the tail plug fit-in section  227  of the base body  220  comes off. The base body  220  is blocked with the flange  245  of the tail plug  220  and also a second projection  242  fits in the tail plug fit-in section  227 . 
   The stopper member  250  which is pushed by the front end section  240   a  of the tail plug  240  causes the core chuck member  230  to shift in an axial direction. 
   Because the claws  232  located at the second slide grooves  212   b  shift to the first slide grooves  212   a  via the taper surfaces  214   c,  the projections  233  on back surfaces of the claws  232  come into contact with the bottom surfaces  214   a  of the first slide grooves  212   a.  Thus, the claws  232  are prevented from spreading out and the stick type cosmetic material C is retained in such a manner that the claws  232  tightly sandwich the stick type cosmetic material C with pressure. 
   The method for retaining the stick type cosmetic material C by shifting the tail plug  240  conforms to the retaining method in the stick type cosmetic material feeding container  1  as shown in FIG.  1 . 
   The holder  301 H shown in FIG.  9 (B) is constituted by an external cylinder  260  having a bottom surface  263  and has at its front end an opening hole  261  capable of housing the cartridge  301 C. The holder  301 H also has on its inner circumferential surface an annular fit-in concave section  262  which moors the cartridge  301 C. 
   Operation of the cartridge type stick-shaped cosmetic material feeding container  301  will be described with reference to FIG.  10 . 
   As described above, the cartridge  301 C in which the stick type cosmetic material C is retained and housed is housed in the holder  301 H. Due to frictional resistance of the inner circumferential surface of the holder  301 H and the base body  220  arising resulting from the O-ring  3  wound to the base body  220 , the base body  220  is united in one body with the holder  301 H and the base body  220  rotates synchronously with the holder  301 H. Therefore, rotary operation of the cartridge  301 C and the holder  301 H corresponds to rotations of the front cylinder  210  and the base body  220 . 
   With respect to the core chuck member  230 , the rotation regulating mechanism operates by engagement of the second slide grooves  212   b  of the front cylinder  210  and the linear projection  235 , and also the feeding mechanism operates due to the spiral engagement mechanism constituted by the spiral  222  of the base body  220  and the large number of engagement projections  239  which are arranged on a surface of the linear projection  235 . Thus, the stick type cosmetic material C retained by the claws  232  advances and retreats through the opening hole  211  provided at a front end of the front cylinder  210  and it is possible to put on makeup. 
   The stick type cosmetic material to be used in each of the above embodiments is not restricted to such a configuration that the cross section is a circular core. Even though the cross section is an elliptical core or a square core, it is possible to sufficiently retain the stick type cosmetic material depending on the shape or the number of claws. Further, it is possible to apply not only to the stick type cosmetic material having a thin diameter, such as an eyeliner and an eyebrow pencil, but also to the stick type cosmetic material having a large diameter, such as a lipstick and foundation. 
   The present invention is not restricted to the embodiments described above. It includes various modifications or improvement which can be made by a person skilled in the art within the scope of the description as set forth in the claims of the present invention.
