Description

The present invention relates to a compact container using a hinge shaft bent in either a U shape or a crank shape.

  Conventionally, a metal compact container is formed by winding a cylindrical instrument hinge piece and a lid hinge piece around the ends of the container body and the lid, respectively, and then sticking a rod-shaped hinge shaft to the instrument hinge piece and the lid hinge piece. A structure has been adopted in which the lid and the container main body are connected so as to be freely opened and closed.

  However, in the case of a hinge mechanism of a cosmetic container, it has been demanded that a part of the hinge shaft is exposed to the outside so that design inconsistency and discomfort do not occur. For this reason, many compact containers are made of plastic with a flexible molding shape so that the cut end surface of the hinge shaft is not visible. However, it is difficult to express the unique high-class feeling of a metal cosmetic container by a decorative expression that is printed, painted, or coated on a plastic surface. In addition, plastic has a low mechanical strength and must be thickly designed to ensure strength. This is sometimes incompatible when trying to reduce weight, thickness and size. For these reasons, cosmetic containers using metals such as aluminum have long been used.

Patent Document 1, a compact case lid hinge tongue lid outer frame and vessel outer frame of the vessel hinge tongue of Patent Document 2, intended to openably connected via a hinge axis, the hinge axis crank-shaped end portion or The holding portion is formed by bending in a U shape. Since the holding part is held between the outer frame and the instrument hinge piece, the hinge shaft is not exposed to the outside and has a good appearance.

  In addition, since the instrument hinge piece holds the hinge shaft holding part in a non-rotatable manner, the rotational resistance that acts on the free stop mechanism of the lid and the opening feeling of the lid is between the lid hinge piece and the hinge shaft. Because it occurs only in the case of, it is possible to easily create the optimal turning resistance.

  Further, Patent Document 1 makes it possible to position the hinge portion of the hinge shaft on which the lid hinge piece is hinged by bringing the hinge shaft holding portion into contact with the bottom surface of the outer frame. However, to fix the hinge shaft to the instrument hinge piece, with the hinge hinge part of the hinge shaft inserted into the cover hinge piece of the lid outer frame, the hinge shaft holder is inserted into the hinge piece and the hinge piece is attached. It is positioned and fixed by bending it into a predetermined shape. For this reason, the fixing operation of the hinge shaft to the instrument hinge piece requires the gripping of the large lid outer frame, which makes it difficult to set to a predetermined position and takes time and effort. The bending and assembling work of the instrument hinge piece has caused the occurrence of defects due to fluctuations in the bent position of the instrument hinge piece, inward tilting, and the reduction of work efficiency.

  Further, in Patent Document 2, when the width of the bearing portion and the bulging portion is made narrower than the width of the holding portion and the holding portion of the hinge shaft is to be inserted into the hinge piece, the hinge shaft is made elastic to the wall surface of the bulging portion. The hinge portion of the hinge shaft to which the lid hinge piece is hinged is positioned by being held in contact with the hinge portion. However, a large force is required when the hinge shaft holding portion that fits into the lid hinge piece is attached to the bearing portion, and a high degree of skill is required for deformation of the bearing portion and assembly work. Such work causes a reduction in assembly work efficiency.

  In the compact container of the present invention, the container body is divided into an inner frame and an outer frame, and a holding portion of a hinge shaft bent in a crank shape or a U shape is sandwiched and fixed between the inner frame and the outer frame.
