Detailed Description

A stick cosmetic container is constructed so that a medium holder is moved into or out of a casing by a driving mechanism. The medium holder has first and second holding members which can be moved relative to each other. The two holding members may be moved in one axial direction relative to each other so that the stick cosmetic is forced forward from one of the holding members. A stopper is provided in association with the two holding members so as to directly restrict the beginning and/or the continuation of the relative movement of the two holding members in the one axial direction.

A conventional lipstick container now commercially available has a single cup-like holding member for accepting a lipstick, which is moved into or out from a casing body. Such a lipstick container is inconvenient in that the lipstick cannot be applied directly on the lips when it becomes short. It is possible but troublesome to remove the remaining lipstick from the bottom of the cup-like holding member by using a fingertip or a brush.Thus, more than a small amount of the lipstick is wasted.
A lipstick container having double holding members has been suggested, in which the remained lipstick can be forced forward by means of relative movement between the two holding members.
However, in this double constructed lipstick container, the two holding members go through unnecessary relative movement, resulting in a problem termed gfalling downh.
On the other hand, a container disclosed in Japanese Utility Model Laid-Open Nos.60-41846 and 60-41847 has two members respectively driven so that the two members are prevented from moving relative to each other unnecessarily. However, in this container, once the lipstick is forced forward by mistake or mischief, it is hard to retract it. So when the lipstick is forced forward excessively, it must be returned by the fingers.
On that account, in spite of the fact that a majority of ladies are willing to use a lipstick container in which the lipstick can be completely used, it remains to be commercialized.
It is an object of this invention to provide a stick applicator which prevents the gfalling downh effect, which is sufficiently reliable to be commercialized, and which is easy to use.
The stick applicator container of the invention includes a stick holding means mounted within and axially movable relative to a casing by means of a driving means. The holding means includes first and second holding members which can be moved relative to each other, the two holding members moving on a common axis relative to each other so that the stick applicator is forced forward relative to one of the holding members. A stopper is provided in the casing in association with the two holding members so as to directly restrict the beginning and/or the continuation of the relative axial movement of the two holding members. 

Another aspect of the invention is provision of a spare stick applicator for mounting in the medium container as a refill.
In a preferred embodiment one of the medium holding members is not deformable in normal use but is deformable when a certain level of force is exerted. A deforming means partially engages and consequently deforms the one holding member on arriving at a predetermined position in the casing. Thus, the one holding member is first moved relative to the casing in a non-deformed condition and is subsequently deformed by engagement with the deforming means so that the stick applicator is forced further forward, moving relative to the one holding member for more accessibility. Preferably, a stopper is provided for restricting the beginning and/or the extent of the deformation of the holding member in such a manner that unless the stopper is unlocked the stick holding means cannot be further deformed.
