Description

[Detailed explanation of the idea] This case relates to a cosmetic compact.

This type of device generally has a body and a lid that are pivotally connected at the rear, and the lid is locked to the body at the front to keep the lid closed. Therefore, when releasing the lock, it is necessary to operate with both hands, and if the lock is hard, the contents may pop out when the lock is released.
Furthermore, even though the lid is locked, external force is often applied while the lid is being carried, and this external force may cause the lid to become unlatched and open by itself.

The present invention aims to eliminate these conventional drawbacks, facilitate the lid opening operation, and prevent the lid from opening naturally.

As shown in the drawings, the present invention is a cosmetic compact in which a body 1 and a lid 2 are pivotally connected 3 at the rear, and the pivoting part 3 is provided with movability for moving the lid 2 forward. In addition, an elastic member such as a leaf spring 4 is attached to the rear part of the body 1 to spring the boss part 5 of the lid 2 backward, and the boss part 5 is given a lever action so that the spring makes the lid 2 1, and further,
A cam means 6 is provided at the front end of the body 1 and the lid 2 to raise the lid as the lid 2 moves forward.

More specifically, the pivot portion 3 between the body 1 and the lid 2 is
A pair of shaft holes 8, 8 which are slightly long in the front and back direction are formed in the inner surfaces of both rear side walls 7, 7 of the lid 2, and a pair of small shafts 9, 9 are protruded from both sides of the boss portion 5 of the lid 2. The shaft is inserted into the shaft holes 8, 8 so as to be movable in the front-back direction.

Further, as shown in FIG.
In addition, the front surface is notched into a slope with the upper end facing backward, and the lower end of the notch is positioned below the center of the shafts 9, 9, and the lower end of the notch is formed into an angular action point 1.
1, and a leaf spring 4 made of an elastic material is pressed against the point of action.

The leaf spring 4 is horizontally long and curved backwards, and its both ends are fitted and fixed into the recesses 12 provided in the rear side walls 7, 7 of the body 1, and the middle part is connected to the point of action 1.
It presses against 1 and fires backwards.

The cam means 6 is formed by forming an inclined surface 13 facing diagonally downward at the front end of the lid 2, and forming an inclined surface 14 facing the inclined surface at the front end of the body 1.

A frame body 15 is installed inside the body 1, and the leaf spring 4 is covered with a flange 16 of the frame body.

In the figure, 17 is a mirror attached to the inner surface of the lid 2.

Because of the above structure, the elasticity of the leaf spring 4 normally exerts a force on the point of action 11 of the boss portion 5 of the lid 2.
Due to this force and the lever action of the boss portion 5, the lid 2 is pressed against the body 1, and the lid is in a closed state.

When the lower part of the boss portion 5 of the lid 2 is pressed forward in this closed state, the lid 2 moves forward a little, and the cam means 6 moves the slope 13 of the lid 2 to the slope 14 of the body 1.
The lid 2 will automatically rise. Due to this rise, the arcuate surface 10 of the boss portion 5 of the lid 2
, the lever action of the boss portion 5 is eliminated, and the pressure of the lid 2 toward the body 1 side is released. After that, all you have to do is rotate the lid 2 sufficiently to open it.

According to the present proposal, the boss portion 5 of the lid 2 can be
By pushing the lower part forward, the lid 2 can be raised, making opening the lid extremely easy. Further, no shock is applied at that time, and no inconvenience such as the contents spilling out occurs.

Furthermore, since the closed lid 2 is pressed against the body 1 by the elasticity of the elastic material, the lid will not open automatically due to external force, and can be carried around without any trouble.

It is simple in structure and manufacture and can be provided at low cost, making it extremely useful in practice.
