Description

  The present invention relates to a feeding mechanism for a stick-shaped decorative material.

  In the stick-shaped cosmetic material feeding container, the front tube and the base tube are rotatably assembled, the female screw tube is integrated in the base tube, the male screw is provided on the outer periphery of the rod shaft of the core chuck member, and the male screw is a female screw of the female screw tube. The feeding mechanism screwed to the head is represented by Japanese Patent No. 2905825, and many applications have been filed.

Patent No. 2905825

  In the feeding mechanism disclosed in Patent Document 1, the core chuck member and the front tube rotate synchronously, so that the rod-shaped decorative material advances along the rotation of the front tube.

  When the texture of the stick-shaped decorative material is soft, the smaller the lead of the feeding, the safer for the consumer.

  However, in the structure of Patent Document 1, when the feeding lead is made small, the male screw of the rod shaft of the core chuck member and the internal thread of the female screw cylinder become strong, and when a further rotational load is applied at the upper limit of the feeding, Therefore, there is a drawback that the fitting of the base tube is easily disengaged, so that it is necessary to enlarge the feeding lead to some extent.

  The present invention solves the above-mentioned problems, and has a structure that can be freely selected from a small feeding lead and a large feeding lead, and even if a small feeding lead or a further rotational load is applied at the upper limit of the feeding, An object is to provide a safe stick-shaped cosmetic material feeding container in which the fitting of the cylinder does not come off.

  The present invention includes a tip tube in which a tip opening hole is formed at the tip and a rod-shaped decorative material is inserted, a base tube that is rotatably assembled to the tip tube, an inner periphery of the base tube, and synchronous rotation. A rod-shaped decorative material supply comprising: a female screw cylinder having a female screw threaded on its periphery; and a core chuck member that is formed on the outer periphery with a male screw that engages with the female screw, and advances and retracts the rod-shaped decorative material by relative rotation between the leading tube and the base tube The tip cylinder is provided with a stopper portion that defines a rising limit of the feeding of the core chuck member on the inner circumference, and the female screw cylinder is provided with a cutting portion formed by cutting a part of the circumference. When a further rotational load is applied to the female screw cylinder after the member comes into contact with the stopper portion, the cutting portion of the female screw cylinder expands, and the female screw repeats screw release and screw return to the male screw.

  According to the present invention, when a further rotational load is applied after the core chuck member comes into contact with the stopper portion that defines the ascent limit provided on the inner periphery of the front tube, the female screw of the female screw tube and the rod of the core chuck member The male screw formed on the outer periphery of the shaft expands the cutting portion, thereby repeatedly releasing the screw and returning the screw to release the screwing force. Therefore, even if the feeding lead is small, it is possible to prevent detachment of the leading tube and the base tube, and at that time, it makes a crackle sound to inform the user that it is the rising limit of feeding.
