ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a case of stick-type cosmetic preparation, which enables a stick-type cosmetic preparation to be readily protruded from and received into the case, and also to a replaceable cartridge of stick-type cosmetic preparation used therefor.
2. Description of the Related Art
Prior art cases of stick-type cosmetic preparation are, for example, disclosed in JAPANESE UTILITY MODEL LAYING-OPEN GAZETTE Nos. 58-12214, 1-82819, and 3-34415. These known cases of stick-type cosmetic preparation have a structure that enables a stick-type cosmetic preparation to be protruded from and received into the case in response to a sliding operation of a predetermined operating member. A sliding operation of the predetermined operating member opens and closes an opening of the case, through which the stick-type cosmetic preparation is lifted up and down. This structure makes the stick-type cosmetic preparation ready for application by a single sliding operation of the operating member.
In the conventionally known cases of stick-type cosmetic preparation, however, the stick-type cosmetic preparation set in the case is exposed to the inner wall of the case, except its lower end portion which is supported by a predetermined support member. There is accordingly a fear that the stick-type cosmetic preparation may come into contact with and be damaged by the opening or the inner wall of the case while stationary or during upward or downward movement of the stick-type cosmetic preparation. In the structures disclosed in the above references, a cover is set in the case while the stick-type cosmetic preparation is protruded from the case. This makes the case undesirably bulky.
The prior art cases of stick-type cosmetic preparation having the structure that allows the stick-type cosmetic preparation to be protruded from the case by a single operation are used only once and thrown away after the stick-type cosmetic preparation has been used up. With the growing concern about the environmental and resource-saving issues, the demand for replacing the contents of daily products and making their cases reusable has been heightened significantly. The cases of daily consumed cosmetic preparation are no except with this demand.
Some replaceable stick-type cosmetic preparations with reusable cases are commercially available from, for example, Meteorite Lipsticks by Guerlain. These replaceable stick-type cosmetic preparations have a separate cap, which is to be removed during use. This structure makes it impossible to prepare the stick-type cosmetic preparation for application by a single operation. A complicated structure is generally required to make the stick-type cosmetic preparation ready for application by a single operation. The complicated structure of the case results in a complicated attachment mechanism of the stick-type cosmetic preparation. When the structure of the attachment mechanism becomes too complicated, the users can not attach and detach the stick-type cosmetic preparation to and from the case by themselves. There have been no cases of stick-type cosmetic preparation having a structure that enables a replaceable stick-type cosmetic preparation to be freely attached to and detached from a compact and reusable case and makes the stick-type cosmetic preparation ready for application by a single operation, while effectively protecting the stick-type cosmetic preparation from damage.
SUMMARY OF THE INVENTION
One object of the present invention is thus to provide a case of stick-type cosmetic preparation having a structure that protects a stick-type cosmetic preparation from damage and makes the stick-type cosmetic preparation ready for application by a single operation.
Another object of the present invention is to provide a case of stick-type cosmetic preparation having a structure that enables a replaceable stick-type cosmetic preparation to be readily attached to and detached from a reusable case.
Still another object of the present invention is to provide a replaceable cartridge of stick-type cosmetic preparation used for such a case.
The above and other related objects are realized by a first case for accommodating a stick-type cosmetic preparation therein to enable the stick-type cosmetic preparation to be freely protrudable from the case. The first case of stick-type cosmetic preparation of the present invention includes: a main body including a tube with an opening on one end thereof; a sleeve for receiving a protruding end portion of the stick-type cosmetic preparation therein, the sleeve being received in the tube of the main body to be freely protrudable from the tube; a support member arranged inside the sleeve for supporting a lower portion of the stick-type cosmetic preparation; and lifting means comprising an operating member attached to the main body to be slidingly movable, a belt having a first end fixed to the operating member and a second end connecting with the sleeve and the support member, and a transmitting mechanism for transmitting a sliding operation of the operating member to a sliding of the sleeve along a longitudinal axis of the tube via the belt, the transmitting mechanism sliding up the sleeve preceding an upward movement of the stick-type cosmetic preparation kept therein until the sleeve reaches the opening of the tube and further sliding up the stick-type cosmetic preparation to a position that enables the protruding end portion of the stick-type cosmetic preparation to be protruded from the sleeve and the opening of the tube.
In the first case of stick-type cosmetic preparation of the present invention, the sleeve is accommodated in the tube of the main body to be freely protrudable from the tube, whereas the support member with a stick-type cosmetic preparation supported thereby is arranged inside the sleeve. A sliding operation of the operating member of the lifting means lifts up and down the sleeve via the belt while lifting up and down the stick-type cosmetic preparation supported by the support member. The transmitting mechanism of the lifting means slides up and down both the sleeve and the stick-type cosmetic preparation via the belt. In accordance with a concrete procedure, the transmitting mechanism slides up the sleeve preceding an upward movement of the stick-type cosmetic preparation until the sleeve reaches the opening of the tube, and then slides up the stick-type cosmetic preparation to a position that enables the protruding end portion of the stick-type cosmetic preparation to be protruded from the sleeve and the opening of the tube. At least the protruding end portion of the stick-type cosmetic preparation is received in the sleeve, which is placed inside the main body. This structure effectively prevents the stick-type cosmetic preparation from being pressed against and damaged by the wall face of the tube of the main body, when the stick-type cosmetic preparation is slid up or down.
In accordance with one preferable application of the first case of stick-type cosmetic preparation of the present invention, the transmitting mechanism of the lifting means holds the sleeve at a predetermined position, for example, at a position where the protruding end of the sleeve projects over the opening, after sliding forward the sleeve via the belt in response to a sliding operation of the operating member, and enables the stick-type cosmetic preparation to be lifted up together with the support member while the sleeve is stationary.
In accordance with another preferable application, the transmitting mechanism of the lifting means moves the stick-type cosmetic preparation at a predetermined sliding rate, which is greater than a sliding rate of the sleeve. For example, the sliding force of the operating member is transmitted to the sleeve via a single-start thread while being transmitted to the stick-type cosmetic preparation via a double-start thread. This makes the sliding rate of the stick-type cosmetic preparation greater than the sliding rate of the sleeve, thereby enabling th
