The female thread cylinder 40 is assembled to the inner periphery of the base cylinder main body 21, the position in the axial direction is defined by the bottom surface 42 of the female cylinder 40 being in contact with the stepped portion 25, and the vertical thread 41 is rotated by engaging with the knurling 24. A directional position is defined.

  The vertical ribs 41 are formed at four locations at intervals of 90 degrees. The vertical rib 41 is formed in a shape corresponding to the knurl 24 of the base tube main body 21.

  The female screw portion 43 is formed in a spiral shape that is continuous with the inner periphery of the female screw cylinder 40. The female thread portion 43 is formed between the protrusions 43a by forming the protrusions 43a having a semicircular cross section projecting spirally on the inner periphery of the female thread cylinder 40.

  As shown in FIG. 2B, the lower end surface 17 of the front tube 10 abuts the upper end of the female screw tube 40 when the stick-shaped cosmetic material supply container 1 is assembled. As a result, the female cylinder 40 is sandwiched between the leading cylinder 10 and the base cylinder main body 21 and its axial position is defined.

  As shown in FIG. 7, the core chuck member 30 includes a decorative material holding portion 31 that holds the stick-shaped decorative material 2, and a rod shaft portion 34 that extends from the decorative material holding portion 31.

  The decorative material holding part 31 has a plurality of claw pieces 31a that sandwich and hold the stick-shaped decorative material 2. As the decorative material holding part 31, a cup-shaped container formed in a bottomed cylindrical shape may be used instead of the claw piece 31a.

  The claw pieces 31a are formed at four positions at intervals of 90 degrees. A portion of the outer peripheral portion of the claw piece 31 a abuts on the guide groove 13 of the front tube 10 and slides on the inner periphery of the guide groove 13.

  The claw piece 31 a is formed so that the tip thereof does not contact the tip of the guide groove 13 in the front tube 10 when the core chuck member 30 is positioned at the upper limit of the feeding. Therefore, even if the core chuck member 30 is further extended at the upper limit of extension, an excessive load is not applied to the claw piece 31a.

  Further, the claw piece 31 a is formed with a small width compared to the width of the guide groove 13. Therefore, the claw piece 31a is not engaged with the circumferential direction of the guide groove 13 to restrict relative rotation, and an excessive load is not applied to the claw piece 31a.

  The rod shaft portion 34 is formed on the outer periphery of the rod portion 38 and engages with the wall portion 14, and the rod shaft portion 34 is formed on the end portion of the groove portion 38 and abuts the lower end portion 14 e of the wall portion 14 to define the extension limit. An abutting portion 37 that is formed between the groove portions 38 and extending from each claw piece 31a, and a cylindrical portion 36 that is formed at the end opposite to the decorative material holding portion 31. Have

  The groove portion 38 is a bottomed groove formed in the axial direction of the rod shaft portion 34. The groove portion 38 is formed in a shape corresponding to the wall strip portion 14 of the front tube 10. The groove portions 38 are formed at four locations at intervals of 90 degrees.

  The contact part 37 is formed at the bottom of the groove part 38. The contact portion 37 is an end portion of the cylindrical portion 36 facing the groove portion 38 because the groove portion 38 is formed up to the end portion of the cylindrical portion 36. The contact portion 37 is formed in each groove portion 38.

  The abutment portion 37 abuts the lower end portion 14 e of the wall strip portion 14 in the front tube 10, thereby defining the upper limit of feeding of the core chuck member 30. If the contact part 37 is in contact with even one place, it is possible to define the extension limit, but in this embodiment, the contact part 37 is in contact with four places to define the extension limit. Therefore, the force acting at the time of contact is distributed in four places, and the design is safer.

  Note that the contact portions 37 may not be provided in all the groove portions 38 but may be provided only in some of the groove portions 38. For example, the contact portion 37 may be provided only in the pair of opposed groove portions 38, and the remaining pair of groove portions 38 may be formed continuously with the cylindrical portion 36.

  As shown in FIG. 8, the ridge 33 has a first ridge 33a extending from the claw piece 31a and a second ridge 33b further extending from the first protrusion 33a. .

  The 1st protruding item | line part 33a is formed in the substantially same diameter as the outer peripheral part of the nail | claw piece 31a. That is, the first ridge 33 a is formed to have an outer diameter that is substantially the same as the inner diameter of the guide groove 13 of the front tube 10. Thereby, the coaxiality of the core chuck member 30 and the front tube 10 is maintained, and the core chuck member 30 is prevented from rattling with respect to the front tube 10. The first ridge 33a always engages with the guide groove 13 in the entire stroke from the feeding ascent limit to the feeding down limit of the core chuck member 30.

  The 2nd protruding item | line part 33b is formed in a small diameter compared with the 1st protruding item | line part 33a. A part of the upper end of the second ridge 33b always engages with the guide groove 13 in the entire stroke from the paying up / down limit of the core chuck member 30 to the drawing down / down limit.

  The second ridge portion 33 b has a male screw portion 35 that protrudes intermittently in the axial direction of its outer periphery and engages with the female screw portion 43 of the female screw tube 40.

  The male thread portion 35 is formed to protrude from the outer periphery of the second ridge portion 33b so that the outer diameter thereof is equal to or smaller than the outer diameter of the first ridge portion 33a. The male screw portion 35 is desirably formed so that the outer diameter thereof is substantially the same as the outer diameter of the first protruding strip portion 33a.

  The male thread portion 35 is formed at a 180-degree interval between the pair of opposing second protruding strip portions 33b. The male thread portion 35 is screwed into the female thread portion 43 of the female thread cylinder 40 and enters the guide groove 13 of the front cylinder 10 and slides in the guide groove 13 when the core chuck member 30 is extended.

  The cylindrical portion 36 is formed to have the same diameter as the second protruding strip portion 33b. The cylindrical portion 36 is integrally formed with the second ridge portion 33b so that the outer peripheral surface thereof is continuous from the outer peripheral surface of the second ridge portion 33b.

  As described above, the rod shaft portion 34 is formed by continuously and integrally forming the protruding strip portion 33 and the cylindrical portion 36. Therefore, the contact portion 37 is provided by forming a bottomed groove portion 38 extending from the base end portion of the claw piece 31a on the rod shaft portion 34 formed in an integral cylindrical shape.

  As described above, in the core chuck member 30, the second protruding portion 33b and the cylindrical portion 36 are formed to have the same outer diameter, and the outer peripheral portion of the claw piece 31a and the first protruding portion 33a are substantially the same outside. Formed in diameter. Since the second ridge 33b is formed to have a smaller diameter than the first ridge 33a, the core chuck member 30 includes a second ridge extending from the outer periphery of the claw piece 31a and the base end of the claw piece 31a. The one ridge 33a is formed with the largest diameter. Since the claw pieces 31 a are formed in a shape corresponding to the stick-shaped decorative material 2, they are not formed to have an extremely large diameter with respect to the stick-shaped decorative material 2.

  Moreover, the contact part 37 which prescribes | regulates the extension raise limit of the core chuck | zipper member 30 is formed in the 2nd protruding item | line part 33b at concave shape. Therefore, since it is not necessary to form the large diameter part for prescribing the upper limit of feeding in the core chuck member 30, the outer diameter of the stick-shaped decorative material feeding container 1 is determined depending on the outer diameter of the stick-shaped decorative material 2. It becomes. Therefore, the outer diameter of the stick-shaped decorative material feeding container 1 can be kept small.

  The cylindrical portion 36 has a male screw small protrusion 35b formed continuously from the male screw portion 35 on the outer periphery thereof.

  The male screw small protrusion 35 b is formed to have a smaller outer diameter than the male screw portion 35. Therefore, in the state where the core chuck member 30 is located at the upper limit of the extension, when a force for further extension is applied, the screw release and the screw return with the female screw portion 43 are repeated. Thereby, the damage of the member by applying an excessive force is prevented.

  Hereinafter, the assembly procedure of the stick-shaped cosmetic material feeding container 1 will be described.

  First, the core chuck member 30 and the female cylinder 40 are assembled. The rear end portion 30 d of the core chuck member 30 is inserted into the female screw cylinder 40. The female thread portion 43 of the female thread cylinder 40 is screwed with the male screw small protrusion 35 b and then screwed with the male screw portion 35. When the female thread cylinder 40 is moved to the uppermost part of the male thread part 35, the assembly of the core chuck member 30 and the female thread cylinder 40 is completed.

  Next, the base cylinder main body 21 is attached. The rear end portion 30 d of the core chuck member 30 is inserted from the front end opening hole 21 a of the base tube main body portion 21. The bottom surface 42 of the female screw cylinder 40 is brought into contact with the step portion 25 and the vertical rib 41 and the knurl 24 are engaged. Thereby, the core chuck member 30 and the base tube 20 are assembled.

  Next, the front tube 10 is attached. The claw piece 31 a of the core chuck member 30 is pushed in while being inserted into the guide groove 13 of the leading tube 10, and the fitting convex portion 18 formed on the fitting portion 16 of the leading tube 10 and the fitting formed on the base tube 20. The recess 22 is fitted. Thereby, the core chuck member 30, the base tube 20, and the front tube 10 are assembled, and the stick-shaped decorative material feeding container 1 is completed.

  In the bar-shaped decorative material feeding container 1 assembled in this way, the core chuck member 30 is located at the lowering limit as shown in FIG. At this time, the lowering limit of the lead chuck member 30 is defined by the contact between the rear end portion 30 d of the lead chuck member 30 and the bottom 23 of the base tube 20.

  Hereinafter, the operation of the stick-shaped decorative material feeding container 1 will be described mainly with reference to FIGS. 1 and 2.

Yes. Therefore, the core chuck member 30 moves in the axial direction and moves up without rotating relative to the front tube 10. Thereby, the rod-shaped decorative material 2 is drawn out from the tip opening hole 11 of the front tube 10 and is in a state where the user can make up.

  If the lead tube 10 and the base tube 20 are rotated relative to each other in the forward direction and the lead chuck member 30 is moved to the upper limit shown in FIG. 2A, the wall strip engaged with the lead chuck member 30 is moved. The lower end portion 14 e of the portion 14 comes into contact with the contact portion 37 formed at the bottom of the groove portion 38. Thereby, the upper limit of the lead chuck member 30 is defined.

  Here, the contact portion 37 is formed at the bottom of the groove portion 38 formed in a concave shape in the rod shaft portion 34 of the core chuck member 30. Therefore, the contact portion 37 does not protrude from the rod shaft portion 34 toward the outer periphery. Therefore, the outer diameter of the stick-shaped decorative material feeding container 1 can be kept small.

  In addition, since it is not necessary to provide a separate stopper member to define the core chuck member 30, assembly is facilitated, and assembly cost can be reduced.

  When the lead chuck member 30 is located at the upper limit of feeding, the tip of the claw piece 31 a does not contact the tip of the guide groove 13 in the front tube 10. Therefore, even if the core chuck member 30 is further extended at the upper limit of extension, there is no burden on the claw piece 31 a that holds the bar-shaped decorative material 2.

  According to the first embodiment described above, the following effects are obtained.

  The upper limit of feeding of the core chuck member 30 is the contact formed at the lower end portion 14e of the wall strip 14 formed on the inner periphery of the front tube 10 and the bottom of the groove portion 38 formed on the outer periphery of the core chuck member 30. It is defined by contact with the portion 37. Therefore, even if the core chuck member 30 is further extended at the upper limit of extension, there is no burden on the claw piece 31 a that holds the bar-shaped decorative material 2. Further, the abutting portion 37 that defines the upper limit of the lead chuck member 30 is formed at the end of the groove portion 38 formed in the rod shaft portion 34 of the core chuck member 30. Therefore, the contact portion 37 does not protrude from the rod shaft portion 34 toward the outer periphery.

  Therefore, the outer diameter of the stick-shaped cosmetic material feeding container 1 can be kept small without imposing an excessive burden on the claw piece 31a holding the stick-shaped decorative material 2.

  9 and 10, the wall strip portion 14 of the front tube 10 may be formed in a wedge shape with a sharp tip so that the claw piece 31a can be easily inserted during assembly. Thereby, the front tube 10 and the core chuck member 30 are easily assembled.
