Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rod-shaped cosmetic dispensing container equipped with a refill case.

[Conventional technology]

Conventional stick-shaped cosmetic dispensing containers, such as Jikko 54
The structure of the rod-shaped cosmetic dispensing container described in Publication No. 21182 (FIG. 8) is as follows, quoting the description in that publication as is. That is, 9 is a holding cylinder for the core P that slides along the reduced diameter cylinder part 5 of the threaded joint 4 and the guide holes 6 and 3 in the shaft head 1 and moves in the vertical direction, and holds the core. 11 has an insertion hole 10 for fitting a polygonal head 12 formed at the rear end into the polygonal hole 8 of the gripping shaft 7, and a threaded portion 11a is screwed into the guide screw 5a of the cylindrical portion 5. 13 is a support and ejecting rod that is attached to the tip of the screw rod 11 and serves as a prism or the like for supporting the holding tube 9 with an enlarged head 13a formed at the tip. They are connected to each other by penetrating them so that they cannot be removed. A coil spring 14 is forcefully interposed between the holding cylinder 9 and the tip of the screw rod so as to surround the ejector rod 13. (Publication No. 54-21182, page 2, left column, lines 14 to 26
row) 〓.

Then, when you have used up all the rod-shaped cosmetics (core),
The remaining rod-shaped cosmetic is ejected from the holding cylinder 9 using an ejector rod 13 and replaced with a new rod-shaped cosmetic.

[Problem that the invention attempts to solve]

However, with conventional stick-shaped cosmetic dispensing containers, when the stick-shaped cosmetic is used up and replaced with a new one,
It is necessary to hold a new replacement bar-shaped cosmetic by hand and insert it into the holding cylinder, and the user gets his hands dirty during this operation. Furthermore, bar-shaped cosmetics differ from pencil leads and the like in that many of them are made of soft materials, so if you hold them in your hands and replace them, there is a risk of them breaking during operation.

The present invention aims to solve these problems and prevents hands from becoming dirty or from breaking the bar-shaped cosmetic when replacing the bar-shaped cosmetic in the bar-shaped cosmetic dispensing container. This is a technical issue.

[Means for solving problems]

In order to solve the above technical problem, the present invention takes the following technical measures.

The rod-shaped cosmetic dispensing container of the present invention has a sliding body 11 slidably provided in a cylindrical main body 1.

The base of the cosmetic material 30 is discharged from the holding part 17 and a replacement bar-shaped cosmetic material 30 is attached to the holding part 17, and a refill case is provided at the base end of the cylindrical body 1.

This refill case is provided with a cylindrical case body 31 integrally with the cylindrical body 1, and an end face of the case body 31 on the opposite side from the cylindrical body 1 is used as an insertion opening 32,
Further, a slit 34 extending in the axial direction is formed in the case body 31, and a sliding portion 1 is provided on the outer surface of the case body 31 to slide forward and backward in the axial direction.
This sliding portion 41 is provided with a protrusion 43 that protrudes from the slit 34 into the case body 31, and further includes:
A refill holder 51 having an opening 52 at one end and closed at the other end is fitted into the case body 31 from the insertion opening 32, and the replacement bar-shaped cosmetic 30 is inserted into the refill holder 51. One end of the refill holder 51 is housed in a form that slightly protrudes from the opening 52, and when the refill holder 51 is inserted into the case body 31,
A contact portion 53 provided on the refill holder 51 is configured to contact the protrusion 43 of the sliding portion 41.

[Effect]

When the sliding part 41 is slid toward the insertion port 32 from the state where the refill holder 51 is inserted into the case body 31, the protrusion 43 of the sliding part 41 pushes out the refill holder 51, so that the refill holder 51 comes out. Holding the refill holder 51 in hand, the protruding replacement bar-shaped cosmetic 30 is inserted from the tip opening 2 of the cylindrical main body 1, and is held in the holding part 17 to complete the replacement of the bar-shaped cosmetic 30.
