This cannot be easily removed from the lid 2 either. This is when carrying a compact container,
Even if an external force such as vibration or drop is applied, the mirror 7 is not detached from the lid 2 or the lid 2 is not detached from the container body 1.

[0004]

In recent years, waste treatment, which has been increasing year by year, has become a social problem, and the need to reduce the amount of waste and to promote resource recycling has increased. For this reason, the number of municipalities that require separate collection is increasing depending on the type of garbage. Also, there is a tendency for manufacturers to be required to recycle containers and packages. However, in the conventional compact container as described above, since the metal pin 6 and the mirror 7 cannot be easily removed from the container body 1 and the lid 2, when the compact container which is no longer used is discarded, the composite A container body 1 and a lid 2 which are resin waste, a metal pin 6 which is metal waste,
The fact is that it is not separated into the mirror 7 which is a glass waste and disposed of, and it is not possible to cope with the separate collection of refuse. Therefore, it has been proposed that the mirror 7 be detachable with respect to the lid 2 so as to be able to cope with the separate collection of refuse. No proposal has been made to remove the metal pin 6, and there is a strong demand for a compact container in which the metal pin 6 can be easily removed.

The present invention has been made in view of such circumstances, and a metal pin used for a hinge connecting portion of a compact container can be easily removed, and metal waste and synthetic resin waste can be removed. It is an object of the present invention to provide a compact container that can be discarded separately.

[0006]

In order to achieve the above object, a compact container according to the present invention comprises a container body, a lid for covering an upper surface of the container body, and a perforation formed at a rear end of the container body. A first hinge shaft insertion hole, a second hinge shaft insertion hole formed in a rear end portion of the lid corresponding to the first hinge shaft insertion hole, and the first and second hinge shaft insertion holes. A hinge shaft that is inserted into the hinge shaft insertion hole and rotatably connects the rear end of the lid to the rear end of the container main body. The hinge shaft has a substantially linear shape in a predetermined temperature range. In a temperature region other than the above-described temperature region, a configuration is adopted in which the entire shape is formed of a shape memory alloy having a substantially linear shape and a bent shape having a bent portion.

A compact container according to a fourth aspect of the present invention has the same configuration as the above-mentioned compact container, and further has a recess formed on the lower surface of the lid, and an annular lens frame is inserted in the recess. A plurality of engaging projections are provided on the inner peripheral surface of the concave portion of the lid at predetermined intervals in the circumferential direction, and the mirror frame is provided on the outer peripheral surface as the mirror frame. One having a plurality of engaged pieces that can be engaged with the joint projection, and having a flange portion projecting inward at the lower portion of the peripheral wall is used, and the upper surface of the flange portion of the lens frame and the lower surface of the concave portion of the lid are used. The mirror frame and the mirror are detachably mounted in the concave portion of the lid by the engagement between the engaging projection and the engaged piece with the mirror interposed therebetween.

That is, the compact container of the present invention is inserted into the first hinge shaft insertion hole at the rear end of the container main body and the second hinge shaft insertion hole at the rear end of the lid, and is inserted into the container main body. The hinge shaft that rotatably connects the two has a substantially linear shape in a predetermined temperature range, and in a temperature range other than the above temperature range,
It is made of a shape memory alloy having a substantially straight shape and a bent shape with a bent portion. In this case, although the shape of the hinge shaft is substantially linear in a predetermined temperature range (for example, about 60 ° C.), a temperature range other than this temperature range (for example, room temperature, etc., allows humans to live a normal life). (Temperature region), the overall shape is substantially linear and has a bent shape with a bent portion (the overall shape is thicker than the linear shape in the predetermined temperature region). Therefore, when attaching the lid to the container body, for example, a hinge shaft that is bent at room temperature is inserted into the hinge shaft insertion hole of the container body and the lid to act as the hinge shaft. When the hinge shaft is removed from the container body and the lid, the rear ends of the container body and the lid are set in a predetermined temperature range, for example, immersed in hot water of about 60 ° C., and the hinge shaft is made substantially linear. Thereby, a gap is formed between the hinge shaft and both hinge shaft insertion holes, and it is easy to remove the hinge shaft from the first and second hinge shaft insertion holes. In this manner, the first hinge shaft insertion hole at the rear end of the container body and the second hinge shaft insertion hole at the rear end of the lid can be obtained simply by immersing the rear ends of the container body and the lid in hot water. The hinge shaft can be easily removed from the hole. Therefore, when this compact container is discarded, the container can be easily divided into a synthetic resin container main body, a lid, and a metal hinge shaft, and there is an advantage that it is possible to cope with sorted collection of refuse. Moreover, when the hinge shaft is to be removed from the container body and the lid, it is only necessary to raise the temperature of the hinge shaft to a predetermined high temperature. In the present invention, the “bent shape having a substantially linear shape and a bent portion” refers to a wavy shape, a saw-tooth shape, a comb-tooth shape, a spiral shape, and the like. The predetermined temperature range may be any temperature range, but is desirably outside a temperature range, such as room temperature, at which humans can live a normal life (differs depending on regions and the like). The area other than the predetermined temperature area includes a temperature area such as room temperature where humans can live a normal life.

According to the compact container of the fourth aspect of the present invention, not only the same effect as in the above-mentioned compact container is exhibited, but also the mirror attached to the lid can be easily removed from the lid. Therefore, there is an advantage that the waste can be separated and collected. And since the said mirror is carefully collect | recovered with another glass waste, there exists no danger of breakage. In addition, the mirror does not fall off when the compact container is carried, even though it can be easily removed.
