ABSTRACT:
TECHNICAL FIELD
The present invention relates to a cartridge type container for feeding a stick type cosmetic material which houses a stick type cosmetic material, such as eyeliner or lipstick, in such a manner that the material can be fed.
BACKGROUND ART
Generally, a cartridge type container for feeding a stick type cosmetic material is composed of a cartridge and a container body. Thus, even though a stick type cosmetic material built in the cartridge is completely used up, the same container body can successively be used by replacing the cartridge with a new cartridge. Further, a single container body can be used for a various colors or shapes of stick type cosmetic materials by replacing a cartridge attached to the container body with another cartridge which has a different color or shape of stick type cosmetic material within.
Incidentally, it is necessary for a stick type cosmetic material, such as eyeliner or lipstick, to be kept clean. Thus, a cartridge type container for feeding a stick type cosmetic material is provided with a cap which covers an opening of the cartridge to be used for feeding the stick type cosmetic material.
However, in the case of a cartridge type container for feeding a stick type cosmetic material having such a cap, it requires much labor for replacing a cartridge. More specifically, when the cartridge is replaced, it is necessary to carry out the following processes: first, the cap is detached, the cartridge is then extracted, further, a new cartridge is installed, and finally, the cap is attached. This is troublesome. Further, it is likely to lose the cap during the replacing work.
The present invention is made in consideration of such problems. An object of the present invention is to provide a cartridge type container for feeding a stick type cosmetic material having a cap to maintain the stick type cosmetic material clean which facilitates the cartridge replacing work.
Further, another object of the present invention is to provide a cartridge type container for feeding a stick type cosmetic material which can prevent the loss of a cap by taking measures to prevent the cap to maintain the cosmetic material clean from coming off the container body.
Further, another object of the present invention is to provide a cartridge type container for feeding a stick type cosmetic material having a cap to maintain the stick type cosmetic material clean which is applicable to various types of feeding and returning mechanisms.
DISCLOSURE OF THE INVENTION
According to the present invention, a cartridge type container for feeding a stick type cosmetic material is provided with a cartridge having a stick type cosmetic material within and a container body which can easily be attached to and detached from the cartridge, wherein the stick type cosmetic material in the cartridge is advanced or returned by relatively rotating the container body and the cartridge in a state that the cartridge is attached to the container body, the cartridge type container further comprising a cap which is composed of a cylinder attached to a periphery of the container body in a manner that the cylinder can slide in an axial direction and never comes off and a lid which is installed at the cylinder and can easily open and close an upper end opening of the cylinder. Due to such constitution, when the cartridge is replaced, the cylinder of the cap can be slid in advance to a position where replacing work will not be interfered, thereby facilitating the replacing work of the cartridge. Further, the cap never comes off the container body, whereby a loss of the cap will not occur during the replacing work of the cartridge.
Further, according to the present invention, on an outside surface of the container body mentioned above, there are provided an upper side stopper section to define an uppermost sliding limit of the cylinder and a lower side stopper section to define a lowermost sliding limit of the cylinder are provided on an outside surface of the container body, respectively, and also an upper side contact section which comes into contact with the upper side stopper section at the uppermost sliding limit of the cylinder and a lower side contact section which comes into contact with the lower side stopper section at the lowermost sliding limit are provided on an inside surface of the cylinder, respectively. Thus, it is possible to simply and reasonably constitute a mechanism which defines the uppermost and lowermost sliding limits of the cylinder and makes it impossible for the cylinder to come off the container body.
Further, according to the present invention, the lid can be closed at least at the uppermost sliding limit of the cylinder and also the lid is pushed open by sliding the cylinder downward. Thus, it is possible to prevent dust from entering through an opening provided at an upper end of the cartridge or an opening provided at an upper end of the container body while the cartridge is removed. Also, the lid is opened only by sliding the cylinder downward, whereby the stick type cosmetic material can be used or the replacing work of the cartridge can immediately be carried out.
Further, the present invention is constituted so that at the lowermost sliding limit of the cylinder, the lid has already descended to a side of the container body, so that the cartridge can be attached to the container body from an upper end opening of the cylinder. Due to such constitution, if the cylinder has been slid to the lowermost sliding limit, the lid will not interfere the replacing work of the cartridge or use of the cosmetic material.
Further, the present invention is provided with a resilient means for urging the lid to a direction of closing the upper end opening of the cylinder. Thus, the lid is automatically closed at least by sliding the cylinder up to the uppermost sliding limit, whereby the cartridge type container for feeding a stick type cosmetic material can be user-friendly.
Further, the present invention is constituted so that the resilient means for urging the lid to a direction of closing the upper end opening of the cylinder are provided, and also at the lowermost sliding limit of the cylinder, the lid has already descended to a side of the container body, so that the cartridge can be attached to the container body from an upper end opening of the cylinder. Due to the constitution, even though the cartridge is not attached to the container body, as long as the cylinder is slid up to the lowermost sliding limit, the lid does not close the upper end opening of the cylinder because the lid is at the side of the container body. Therefore, the lid will not interfere the replacing work of the cartridge.
Further, the present invention is provided with synchronous rotation means for synchronously rotating the cylinder and the container body is provided. Thus, if a user holds the cylinder and the container body and relatively rotates them, the stick type cosmetic material can be fed or returned. Therefore, the cartridge type container for feeding a stick type cosmetic material can be user-friendly.
Further, the present invention is constituted so that the synchronous rotation means synchronously rotate the cylinder and container body no matter where the cylinder is at between the uppermost sliding limit and the lowermost sliding limit. Thus, the cap slides always straight to the container body, whereby the cartridge type container for feeding a stick type cosmetic material can be user-friendly.
