  According to such a bar-shaped cosmetic material feeding container, it is possible to operate a so-called torque limiter in which the screw rod is idled by releasing the screwing of the male screw and the female screw when excessive torque acts on the screw rod. This makes it possible to prevent the container from being destroyed.

  By the way, the conventional torque limiter in this kind of stick-shaped cosmetic material supply container is realized by adopting means for devising the structure of the engaging portion of the screw rod and the sleeve or the engaging portion of the screw rod and the main body in some sense. However, since no means other than such means have been proposed, there are currently limited technology options.

  Then, the subject of this invention is providing the stick-shaped cosmetics delivery container which can prevent destruction of a container by the separate structure completely different from the former.

In order to solve the above-mentioned problems, a bar-shaped cosmetic material supply container according to the present invention is a front side having a core chuck that holds a bar-shaped cosmetic material at the tip and a rotation stopper at a rear end spaced from the core chuck. And a second rod-shaped member on the outer periphery of which a male screw is formed on the outer periphery, and a cylinder having an interior that supports the screw rod in a non-rotatable and axially slidable manner A cylindrical sleeve, which is rotatably connected to the sleeve from the rear side about the axis, and a non-rotatably mounted cylindrical member having a female screw that engages with the male screw of the screw rod formed on the inner periphery A bar-shaped cosmetic material feeding container for feeding out a bar-shaped cosmetic material held on the screw rod by rotating the sleeve and the main body relative to each other, the screw rod comprising a first rod-shaped member and a second rod-shaped member. Enables synchronous rotation with normal torque, and Are linked via a coupling means capable of operating the torque limiter by allowing idling with a large torque, connecting means, the tip of the rear end portion or the second rod-like member of the first rod-like member The shaft portion provided on the outer periphery and formed with a protrusion or groove extending in the axial direction on the outer periphery is provided at the tip end portion of the second rod-shaped member or the rear end portion of the first rod-shaped member, and the shaft portion on the inner periphery. In the socket in which the groove or the protrusion that fits the protrusion or the groove is formed, the protrusion and the groove are connected by being fitted so as to fit.

  According to such a bar-shaped cosmetic material supply container, the screw bar connects the first bar-shaped member and the second bar-shaped member to a state in which synchronous rotation by normal torque is possible and idling by excessive torque is possible. Therefore, the torque limiter has a separate structure that is completely different from the conventional technical means in which the structure of the engaging portion of the screw rod and the sleeve or the engaging portion of the screw rod and the main body is devised in some sense. Can be operated, thereby preventing the container from being destroyed.

  Therefore, according to this, it is possible to widen the choice of technology, that is, contribute to the enrichment of technology.

  From such a technical point of view, it is possible to reliably avoid the problem that the synchronous rotation at the normal torque or the idling at the excessive torque cannot be avoided and to prevent the destruction of the container more surely. The connecting means is provided at the rear end portion of the first rod-shaped member or the tip portion of the second rod-shaped member, and the shaft portion formed with a protrusion or groove extending in the axial direction on the outer periphery is connected to the second rod-shaped member. The protrusion and the groove are fitted in a socket provided at the tip of the first member or the rear end of the first rod-like member and having a groove or protrusion that fits the protrusion or groove of the shaft portion on the inner periphery. It is preferable that they are connected by being inserted into.

Further, from the viewpoint of more reliably avoiding the problem that the synchronous rotation at the normal torque or the idling at the excessive torque will not occur, and the destruction of the container is more reliably prevented, the connecting means is it is preferred that one of ridges and grooves an elastic body.

Further, the rod-shaped cosmetic material held on the screw rod is fed out so as not to cause a problem that the connection between the first rod-shaped member and the second rod-shaped member is released by the removal of the shaft portion fitted in the socket. From the viewpoint of securing the original function of the stick-shaped cosmetic material delivery container, the connecting means is a pull- out that prevents the connection between the first bar-shaped member and the second bar-shaped member from being released. And means for preventing the removal of the shaft when the synchronous rotation by the normal torque or the idling by the excessive torque is performed by at least the first rod member and the second rod member. It is preferable to prevent the portion from being removed from the socket .

  According to the stick-shaped cosmetic material feeding container according to the present invention, it is possible to operate the torque limiter with a separate configuration completely different from the conventional technical means, which contributes to the enrichment of the technology.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Is a longitudinal sectional view showing the configuration of the screw rod, FIG. 5 is a perspective view showing the configuration of the screw rod, FIG. 6 is a longitudinal sectional view showing the configuration of the sleeve, FIG. 7 is a perspective view showing the configuration of the sleeve, and FIG. FIG. 9 is a perspective view showing the configuration of the main body.

  In this Embodiment, the stick-shaped cosmetic material supply container is comprised as what is used for the objective of paying out and using the eyebrow 10 which is a stick-shaped cosmetic material in which a user is incorporated, for example (refer FIG. 1).

  And this rod-shaped cosmetic material supply container is comprised as a thing provided with the screw rod 1, the cylindrical sleeve 2, and the cylindrical main body 3 as shown in the figure.

  Hereinafter, each of these components will be described in more detail.

  (1) Screw rod 1

  As shown in FIGS. 1 to 5, the screw rod 1 has a core chuck 11 a that holds the eyebrow 10 at the tip, and has a male screw 12 a formed on the outer periphery.

  Such a screw rod 1 can be accommodated and assembled in a sleeve 2 and a main body 3 to be described later, and as a result, the sleeve 2 and the main body 3 are held on the screw rod 1 by relative rotation. It is possible to realize the basic configuration of the stick-shaped cosmetic material supply container that can supply the eyebrow 10.

  In the present invention, the screw rod 1 is divided into a first rod-shaped member 11 and a second rod-shaped member 12 having the same axis. The first rod-like member 11 and the second rod-like member 12 are configured to be connected via a connecting means 13 that enables synchronous rotation by normal torque and idling by excessive torque. (See FIG. 1 and FIGS. 3 to 5).

  Specifically, as shown in these drawings, the connecting means 13 is provided at the rear end portion of the first rod-shaped member 11 and opens to the rear side, and the second rod-shaped member 12 is connected to the socket 13a. The shaft portion 13b is provided at the tip portion and is to be inserted into the socket 13a. ,

  As shown in FIG. 3, the shaft portion 13 b is formed with a protrusion 41 that protrudes outward and extends in the axial direction. On the other hand, as shown in the figure, the socket 13a is formed with a groove 42 that fits with the protrusion 41. At least one of the protrusion 41 and the groove 42 is configured as an elastic body.

  In short, the connecting means 13 connects the shaft portion 13b by fitting the shaft portion 13b into the socket 13a so that the protrusion 41 and the groove 42 fit into each other.

  Thus, the screw rod 1 requires that the first rod-like member 11 and the second rod-like member 12 be connected to the screw rod 1 in a state enabling idling by excessive torque. By releasing the synchronous rotation of the first rod-shaped member 11 and the second rod-shaped member 12 when an excessive torque acts on the rod-shaped makeup, it is possible to operate the torque limiter with a completely different configuration from the conventional one. This is to make the material feeding container. Therefore, if it plays such a role, instead of the connecting means 13 having the protrusion 41 and the groove 42 fitted to the protrusion 41 in the present invention, for example, a connecting means not having the protrusion 41 or the groove 42 is provided. It is possible to use other connecting means that enables idling by excessive torque by adjusting the degree of frictional resistance acting between the socket 13a and the shaft portion 13b.

  In addition, it is required that the screw rod 1 is connected to the screw rod 1 in a state enabling synchronous rotation by normal torque. Among the screw rods 1 capable of idling by excessive torque, synchronous rotation by normal torque is required. In order to secure the basic function of the bar-shaped cosmetic material feeding container, in which the eyebrow 10 held on the screw rod 1 is fed by rotating the sleeve 2 and the main body 3 relative to each other by eliminating the screw rod 1 that cannot be used. is there. Therefore, if it plays such a role, instead of the connecting means 13 having the protrusion 41 and the groove 42 fitted to the protrusion 41 in the present invention, for example, a connecting means not having the protrusion 41 or the groove 42 is provided. It is possible to use other connecting means that enables synchronous rotation by normal torque by adjusting the degree of frictional resistance acting between the socket 13a and the shaft portion 13b.

  In the present embodiment, the connecting means 13 has an anti-extraction means 13c that prevents the shaft portion 13b fitted and inserted into the socket 13a from being extracted from the socket 13a.

  By such connecting means 13, it is possible to prevent a problem that the connection between the first rod-shaped member 11 and the second rod-shaped member 12 is released by the removal of the shaft portion 13 b inserted into the socket 13 a. Thus, it is possible to ensure the original function of the stick-shaped cosmetic material supply container according to the present embodiment of paying out the eyebrow 10 held on the screw rod 1.

Further, as shown in FIGS. 1 to 5, the screw rod 1 is configured to be provided with a rotation stopper 14.
Specifically, as shown in FIGS. 1, 4 and 5, the rotation stopper 14 is provided on the rear side of the lead chuck 11 a at a distance from the lead chuck 11 a, and as shown in FIG. 1. The screw rod 1 is configured to regulate the maximum amount of the feeding operation.

  Here, as shown in FIG. 1, the rotation stopper 14 provided on the rear side of the core chuck 11a at a distance from the core chuck 11a is required to restrict the maximum feeding operation of the screw rod 1. This is a stick-shaped cosmetic material feeding container capable of reducing the load generated in the core chuck 11a as much as possible by causing the rotation stopper 14 to play a role as a stopper member for restricting the maximum of the feeding operation. This is because. Therefore, if it plays such a role, it is adjacent to the rear side of the core chuck 11a instead of the rotation stopper 14 provided on the rear side of the core chuck 11a at a distance from the core chuck 11a in the present invention. A provided anti-rotation or other anti-rotation can be used.

  As shown in FIG. 1, in the sleeve 2, the rear side of the sleeve 2 is set to have a larger inner diameter than the front side of the sleeve 2, so that the gap between the front side of the sleeve 2 and the rear side of the sleeve 2 is set. Although the step 22 is formed, the maximum restriction of the feeding operation of the screw rod 1 is performed by bringing the portion 14 a of the rotation stopper 14 into contact with the step 22.

  (2) Sleeve 2

  As shown in FIGS. 1 to 3 and FIGS. 6 and 7, the sleeve 2 has a cylindrical shape and has an inner portion 21 that supports the screw rod 1 so as not to rotate and to be slidable in the axial direction. It is configured as.

  With such a sleeve 2, the screw rod 1 can be accommodated and assembled in the inside 21 together with the main body 3 to be described later. As a result, the sleeve 2 and the main body 3 are relatively rotated and held on the screw rod 1. Thus, it is possible to realize the basic configuration of the stick-shaped cosmetic material supply container that can supply the eyebrow 10.

  (3) Body 3

  As shown in FIG. 1, the main body 3 has a cylindrical shape, and is connected to the rear portion of the sleeve 2 so as to be rotatable about an axis.

  As shown in FIGS. 1, 8, and 9, the main body 3 protrudes inwardly from the inner side of the rear side of the female screw 31 and the female screw 31 that engages with the male screw 12 a of the screw bar 1. The stopper 33 is a rib extending in the axial direction.

  Here, as shown in FIG. 1, the female screw 31 is mounted with a cylindrical member having an inside in which the female screw 31 is formed in the main body 3 in a non-rotatable manner, and between the rear end of the sleeve 2 and the stopper 33. It is embodied by sandwiching and fixing between them.

  Such a main body 3 allows the screw rod 1 to be housed and assembled in the interior 21 together with the sleeve 2, and as a result, the eyebrow held by the screw rod 1 by relatively rotating the sleeve 2 and the main body 3. It is possible to realize a basic configuration of a stick-shaped cosmetic material supply container that can supply 10.

  In the present embodiment, as shown in FIG. 1, an O-ring 4 is mounted between the sleeve 2 and the main body 3, so that the sleeve 2 and the main body 3 can be appropriately rotated. A rotational resistance is to be secured (see FIGS. 6 and 7).

  As described above, in the rod-shaped cosmetic material supply container according to the present embodiment, the screw rod 1 can rotate the first rod-shaped member 11 and the second rod-shaped member 12 synchronously with normal torque and idle with excessive torque. It is comprised by connecting in the state which is possible.

  Therefore, according to such a bar-shaped cosmetic material supply container, it is completely different from the conventional technical means in which the structure of the engaging portion of the screw rod and the sleeve or the engaging portion of the screw rod and the main body is devised in some sense. The torque limiter can be actuated by different and separate configurations, thereby preventing the container from being destroyed.

  Therefore, according to this, it is possible to widen the choice of technology, that is, contribute to the enrichment of technology.

  As mentioned above, in this Embodiment, although the case where eyebrow was used as a stick-shaped cosmetic was demonstrated, this invention is not limited to such an embodiment. For example, the present invention can be widely applied when using an eyeliner, a lip liner, a concealer, or other stick-shaped cosmetics.
