Description

[Detailed explanation of the invention] This invention is a rod-shaped cosmetic that can be used at both ends, such as eyeliner, eyebrow, eye shadow, lipstick, etc., by making it appear and retract from both ends of the barrel. This invention relates to a dispense-type cosmetic container.

Conventionally, a device in which two sliding shafts for dispensing cosmetics from both ends of the barrel are installed in series is known as a device that dispenses cosmetics from both ends of the barrel. The disadvantage was that the entire container was long despite the small amount of material. As an alternative to this,
Those shown in Japanese Utility Model Publication No. 10932 and Japanese Utility Model Publication No. 56-25615 are publicly known. Although these containers have a short overall length, the former has a core bar with a screw carved into it for feeding out the cosmetics, and a pipe with grooves cut in the longitudinal direction to form a feeding mechanism. In the latter case, the feeding mechanism that feeds out the cosmetics is made up of a long and thin screw leg, and in both cases, radial deflection occurs between this leg and the female screw threaded to ensure reliable and smooth operation. The problem was that it was difficult to operate.

This idea was developed in view of the above-mentioned drawbacks of the conventional technology.The first core cylinder and the second core cylinder are attached to both ends of a threaded cylinder that is installed in the shaft cylinder and has threaded bodies on the inner and outer peripheries. The core tubes are rotatably connected to each other, and the first
A first sliding body for dispensing cosmetics is fitted into the core cylinder, and the first sliding body is connected to the outer peripheral screw body of the screw cylinder.
It engages in a feeding mechanism composed of a core tube so that it can move forward and backward,
On the other hand, a second sliding body for dispensing the cosmetic material is fitted into the second core cylinder, and the second sliding body can be moved forward and backward into the dispensing mechanism constituted by the inner circumferential screw body of the threaded cylinder and the second core cylinder. By engaging with each other, the entire container can be made compact, and a dispensing mechanism with reliable and smooth dispensing operation can be constructed.In addition, the cosmetics at both ends can be dispensed independently and can be used as desired. The purpose is to obtain a good cosmetic container.

The configuration of this invention will be described in detail below with reference to the embodiments shown in the drawings. FIGS. 1 and 2 are the basic first embodiment, and FIGS. 3 and 4 are the second embodiment.
