  However, in the pencil-type container, there is a gap necessary for assembly between the engaging protrusion and the engaging groove that are engaged with each cylinder so as not to be relatively rotatable. When a bending force is applied to the outside from the outside, the amount of bending deformation is large compared to the case where the cylindrical container is not divided, and particularly when the core material is a rod-shaped cosmetic, the rod-shaped cosmetic is There is a risk of breakage.

The present invention has been made to solve such problems, and provides a pencil-type container and a method for assembling the pencil-type container in which damage to a core material such as a stick-shaped cosmetic is prevented. Objective.

A pencil type container according to the present invention is a pencil type container including a cylindrical container that accommodates a core material and allows the core material to be advanced and retracted from an opening at a front end thereof. A plurality of cylindrical containers are formed in a circumferential direction. An inner cylinder having the projected portion or groove portion on the outer surface, and at least the distal end side of the inner tube, and a plurality of projections or groove portions are formed corresponding to the projection or groove portion so that the protrusion or groove portion enters the axial direction and is not relatively rotatable. And an outer cylinder having an engaging groove or protrusion on the inner surface, the inner cylinder is immovable in the axial direction with respect to the outer cylinder, and the engaging protrusion and the groove have thicknesses on their side surfaces. It is characterized by being configured in a shape that restrains the movement in the direction.

  According to such a pencil-type container, a plurality are provided on each of the inner surface of the outer cylinder and the outer surface of the inner cylinder, and the protrusions to be engaged and the side surfaces of the groove are configured to constrain the movement in the thickness direction. Therefore, the movement in the thickness direction, which is not prevented by the side surfaces of the protrusion and the groove portion having a substantially rectangular cross section in the past, is easily prevented, and the bending deformation amount when the bending force acts on the cylindrical container is reduced. It is made smaller. In addition, the pencil-type container is generally tapered, and as the distance from the front end side to the rear side increases, the thickness difference increases and there is a risk of causing sink marks (including voids). Since the inner cylinder and the outer cylinder that covers at least the distal end side of the inner cylinder are divided, the thickness difference between the outer cylinder and the inner cylinder is reduced.

  Here, when the side surface is an inwardly extending or outwardly extending inclined surface, the above-described operation can be achieved with a simple configuration.

When the support 21 is retracted to the retreat limit, the bar-shaped cosmetic M is stored in the cylindrical container 20. It is submerged from the opening 20e at the tip of and is accommodated in the bar-shaped cosmetic cartridge 2.

  Further, when the bar-shaped cosmetic cartridge 2 is pulled out of the container 3 against the engagement between the protrusion 14 of the holder 4 and the annular groove 20j of the inner cylinder 11, the pressing force of the pressing bar 9 against the support 21 Therefore, the support 21 is retracted to the retreat limit by the urging force of the compression spring 23, and the bar-shaped cosmetic M is submerged from the opening 20 e at the tip of the cylindrical container 20 and accommodated in the bar-shaped cosmetic cartridge 2. Is done. For this reason, in the state where the stick-shaped cosmetic cartridge 2 is removed, the clothes, fingertips, handbags and the like are prevented from being soiled.

  In such a bar-shaped cosmetic supply container 1, particularly in the present embodiment, as shown in FIG. 8, the protrusion 11c of the inner cylinder 11 has a substantially fan-shaped cross section including an outwardly extending inclined side surface 11d. In addition, the groove portion 10c of the outer cylinder 10 into which the ridge 11c enters is formed in a shape that is substantially similar to and close to the transverse cross-sectional shape of the ridge 11c.

  That is, the protrusions 11c of the inner cylinder 11 and the side surfaces 11d and 10d of the groove portion 10c of the outer cylinder 10 are configured to constrain the movement in the thickness direction, and the movement of the inner cylinder 11 toward the inner side of the protrusion 11c is performed. Since it is constrained by the groove 10c of the outer cylinder 10 (when viewed from the outer cylinder 10, the outward movement of the groove 10c of the outer cylinder 10 is constrained by the protrusion 11c of the inner cylinder 11), the conventional transverse cross section is substantially omitted. Movement in the thickness direction, which is not blocked between the rectangular protrusions and the side surfaces of the groove, is easily blocked. For this reason, the amount of bending deformation of the cylindrical container 20 when a bending force is applied to the cylindrical container 20 is reduced, and damage such as breakage of the bar-shaped cosmetic M is prevented.

  Further, as shown in FIGS. 3 and 4, the cylindrical container 20 is thus divided into the inner cylinder 11 and the outer cylinder 10 covering the distal end side of the inner cylinder 11. As the outer cylinder 10 is integrally molded and becomes tapered away from the front end side to the rear side, the thickness difference increases, resulting in an increase in the thickness difference and the possibility of causing sink marks (including voids). The thickness difference between each part of the cylinder 10 and the inner cylinder 11 is reduced, and the sink mark is prevented.

  Moreover, in the stick-shaped cosmetic material supply container (pencil-type container) described in JP-A-11-75934, which is a type in which the support is pushed out by a push bar and returned by an elastic body, the opening at the rear end of the cylindrical container, Since it has a configuration in which a tail plug having an opening at the center that allows the push rod to be advanced and retracted is inserted and fitted, when the stick-shaped cosmetic supply container equipped with this cylindrical container is dropped, for example, against the tail plug In addition, there is a possibility that the impact force toward the rear side due to the weight of the bar-shaped cosmetic material and the support that supports the rod-like cosmetic material acts, and the tail plug may be detached rearward in the container, but in this embodiment, FIG. As shown in FIG. 4 and FIG. 4, the outer periphery of the inner cylinder 11 is not affected even if an impact force that drops the stick-shaped cosmetic material supply container 1 and moves toward the rear side acts on the bag portion 20 h of the inner cylinder 11 via the slit pipe 22. An annular protrusion 11a ( Part) is abutted against the front end surface of the container 3, so that the rearward movement of the inner cylinder 11 is prevented and the inner cylinder 11 is not detached from the outer cylinder 10, and the quality and reliability are improved. Is planned. In addition, the step part of the inner cylinder 11 does not necessarily need to be an annular protrusion, and may be configured such that a plurality of protrusions (steps) are abutted against the distal end surface of the container 3.

  Furthermore, in this embodiment, the support body 21 is incorporated in the slit pipe 22, the slit pipe 22 and the compression spring 23 are inserted from the distal end side of the inner cylinder 11, and the outer cylinder 10 is placed on the distal end side of the inner cylinder 11. Since the covering assembly method is employed, it is easy to provide a support 21 that is a large-diameter support 21 that supports the thick stick-shaped cosmetic M and cannot be inserted into the cylinder from the rear end side of the cylindrical container 20. It is possible to assemble.

  The bar-shaped cosmetic M is not limited to a circular shape but may be an oval shape, and the above-described spiral groove 12a, screw projection (projection) 21b, etc. are screws having the same functions as these. If it is in the shape,

  18 is a cross-sectional view showing a stick-shaped cosmetic material supply container according to the second embodiment of the present invention, corresponding to the view taken along arrows VIII-VIII in FIG. 4, and FIG. 19 is a third embodiment of the present invention.

In addition, in place of the groove portion 10c of the outer cylinder 10, the groove portion 10e is used in the second embodiment, and the groove portion 10g is used in the third embodiment.

  In the second embodiment, as shown in FIG. 18, the protrusion 11e of the inner cylinder 11 has a shape in which both side surfaces 11f and 11f expand stepwise toward the outside (the spread is one step). At the same time, the groove portion 10e of the outer cylinder 10 into which the ridge 11e enters is formed in a shape that is substantially similar to and close to the cross-sectional shape of the ridge 11e.

  That is, the protrusions 11e of the inner cylinder 11 and the side surfaces 11f and 10f of the groove portion 10e of the outer cylinder 10 are configured to constrain the movement in the thickness direction, and the movement of the inner cylinder 10 toward the inner side of the protrusion 11e is performed. The outer cylinder 10 is constrained by the groove 10e (when viewed from the outer cylinder 10, the outward movement of the groove 10e of the outer cylinder 10 is constrained by the protrusion 11e of the inner cylinder 11). Therefore, substantially the same effect as the first embodiment can be obtained.

  Further, in the third embodiment, as shown in FIG. 19, the protrusion 11g of the inner cylinder 11 has inclined side surfaces 11h, 11h that are inwardly spread, and the cross section of the first embodiment is substantially the same. The shape is such that the fan-shaped shape is turned upside down, and the groove portion 10g of the outer cylinder 10 into which the protrusion 11g enters is substantially similar to the cross-sectional shape of the protrusion 11g and is close to the shape. Has been.

  That is, the protrusions 11g of the inner cylinder 11 and the side surfaces 11h, 10h of the groove portion 10g of the outer cylinder 10 are configured to constrain the movement in the thickness direction, and the outward movement of the protrusion 11g of the inner cylinder 11 is prevented. It is restrained by the groove 10g of the outer cylinder 10 (when viewed from the outer cylinder 10, the inward movement of the groove 10g of the outer cylinder 10 is restrained by the protrusion 11g of the inner cylinder 11). Therefore, substantially the same effect as the first and second embodiments can be obtained.
