ABSTRACT:
TECHNICAL FIELD
The present invention relates to a cartridge of make-up container and make-up material container.
BACKGROUND ART
With regard to a cosmetic container which feeds out a stick type cosmetic material housed in a cartridge, such as eyeliner, eyebrow pencil, eye shadow, or lipstick, through an opening provided at an upper end of the cartridge due to rotations of the cartridge and a container body, there are proposals, for example, in Japanese Patent Laid-Open Publication No. Sho 60-48706, Japanese Utility Model Publication No. Hei 4-30961, and the like.
Further, with regard to a cosmetic container, among the cosmetic containers described above, in which if a cartridge is removed from a container body, a stick type cosmetic material fed out of the cartridge will automatically be housed in the cartridge, there are proposals, for example, in Japanese Utility Model Publication No. Hei 3-50814 and Japanese Utility Model Publication No. Hei 6-21390 which have been applied by the applicant of the present invention.
In a cosmetic container disclosed in Japanese Utility Model Publication No. Hei 3-50814 among them, a feeding mechanism is installed at a container body. As a cartridge fitted to the container body rotates, the feeding mechanism actuates and feeds out an extrusion beam which is installed at the container body in such a manner that the extrusion beam can slide in an axial direction. Pressed out by the extrusion beam, a stick type cosmetic material in the cartridge is fed out. Further, a return spring is provided at the extrusion beam and a support member for the stick type cosmetic material, respectively, and when the cartridge is removed from the container body, these return springs automatically return.
Further, in a cosmetic container disclosed in Japanese Utility Model Publication No. Hei 6-21390, a feeding mechanism is provided on the side of a cartridge, and a shaft is installed at the container body in a standing position. The shaft is a guide shaft for a push rod which is fed out by the feeding mechanism and the shaft is engaged with the push rod in such a manner that the shaft cannot rotate, but can slide in an axial direction. Thus, when the container body and the cartridge rotate, the push rod rotates to the cartridge, the push rod is fed out by the feeding mechanism, and a stick type cosmetic material retained at an upper end of the push rod is fed out. Further, a return spring for pushing back the push rod to an initial position is provided on the cartridge side, and it is arranged such that when the cartridge is removed from the container body, the stick type cosmetic material is drawn back to an initial position.
However, in the cosmetic container disclosed in Japanese Utility Model Publication No. Hei 3-50814 described above, when the cartridge is removed from the container body, the extrusion beam on the container body side and the support member for the stick type cosmetic material on the cartridge side are returned, respectively. Thus, separate return springs are required and a cost of the entire cosmetic container increases. Further, overall length of the cosmetic container has to be approximately the sum total of the length of the cartridge and the length of the extrusion beam, whereby the cosmetic container becomes huge.
On the other hand, the cosmetic container disclosed in Japanese Utility Model Publication No. Hei 6-21390 has the advantages that only a single return spring is required and the overall length of the cosmetic container can relatively be short. However, in the cosmetic container, the shaft having a length at least equivalent to a stroke of the push rod has to be installed at the container body in a standing position, whereby constitution of the container body becomes complicated. Further, it is necessary that a hole in which the shaft is engaged is formed at the push rod, whereby a certain thickness is required. Therefore, the cosmetic container has to be thick by a portion equivalent to a thickness of the push rod, whereby it is difficult to be applicable to a cosmetic material having a thin diameter. Further, the push rod and the container body synchronously rotate during operation of the feeding mechanism. Therefore, in order to prevent the stick type cosmetic material fed out from rotating to the front cylinder of the cartridge, it has to be constituted such that the support member for the stick type cosmetic material is separated from the push rod, whereby constitution of the cartridge becomes complicated.
DISCLOSURE OF THE INVENTION
An object of the present invention is to provide a cartridge for a cosmetic container or the cosmetic container in which a stick type cosmetic material automatically returns by removing the cartridge, constitution of a container body can be simplified, it is possible to apply to a various kinds of stick type cosmetic materials, and operation of automatic return is stabilized.
In order to achieve the object described above, the present invention provides a cartridge for a cosmetic container or the container having the following constitution.
In a cartridge for a cosmetic container which is installed at a container body in such a manner that the cartridge can easily be attached and removed, houses and retains a stick type cosmetic material therein, and moves the stick type cosmetic material forward and backward through an opening provided at an upper end by a rotation together with the container body, there are provided a front cylinder having the upper end opening and a cylindrical body at least a part of which is housed in the front cylinder in such a manner that the cylindrical body can rotate, but cannot slide. A cartridge body is composed of the front cylinder and the cylindrical body. A beam is housed in the cartridge body and a cosmetic material retaining section for retaining the stick type cosmetic material is formed on the side of an upper end of the beam. There are provided a sliding mechanism for retaining the beam in the front cylinder in such a manner that the beam cannot rotate, but can slide, a feeding mechanism for feeding out the beam in an axial direction by relative rotations of the beam and the cylindrical body, and a spring for always urging the beam backward. A synchronous engagement means which is synchronously engaged with the container body is installed at a lower end part of the cylindrical body.
The stick type cosmetic material does not rotate to the front cylinder and therefore the stick type cosmetic material makes a stroke in a smooth and stable manner. Thus, for example, even in the case that the stick type cosmetic material automatically returns, it is hard for the stick type cosmetic material to break.
Further, since the container body is connected with the cylindrical body via the synchronous engagement means, when the cartridge is drawn out of the container body, the stick type cosmetic material automatically returns. Therefore, feed-down operation can be facilitated and also constitution of the container body can be simplified with a function to prevent the stick type cosmetic material from breaking being held.
Further, the beam can have a thin diameter because it is not necessary to provide a hole to be used for connecting the beam with the container body, whereby a diameter of the cartridge body can sufficiently be small. Therefore, it is possible to easily constitute the cosmetic container which is applicable to a stick type cosmetic material having a thin diameter.
When the cylindrical body is entirely housed in the front cylinder, an outer frame of the cartridge is composed of the front cylinder which is a single member. Thus, when the cartridge is removed from the container body, if the cartridge is kept to be a single unit, a user cannot rotate the front cylinder and the cylindrical body while holding them. In other words, unless the cartridge is installed at the container body, operation of feeding out the stick type cosmetic material from the cartridge will not be carried out. Thus, it is possible to prevent the stick type cosmetic material from br
