Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a one-touch operation type cosmetic compact that automatically opens a lid when a stopper plate is unlocked.

[Prior Art] As is well known, this type of one-touch operation type is equipped with a driving torsion spring, for example, in a notch groove on the end surface of the hinge boss side of the lid side, and one mustache of this torsion spring is attached to the lid side. On the hinge boss of the other side, lock the other beard on the back surface of the rear wall of the cosmetic dish, store this torsion spring by closing the lid and always apply a force in the opening direction to the lid, and unlock the stopper plate. When the lid is unconstrained, the lid automatically opens upward due to the elastic force.

"Problems to be solved by the invention" As the torsion spring, one having sufficient elasticity is used.
The lid is made to open surely upward, so that the lid pops up vigorously so that the lid often pops up.

The present invention provides a one-touch operation type cosmetic compact that has a structure in which a torsion spring for opening the lid is acted by slidingly contacting the rear surface of the rear wall of the cosmetic dish so that the lid can be opened slowly while having sufficient elasticity. It is in.

[Means for Solving the Problems] The cosmetic compact of the present invention is a cosmetic dish with a front side half surface including a hinge pin hole 3 on one side end surface of a hinge boss 2 hanging down from a rear end edge of a lid 1 and a front side. 4 A rear wall 5 is opened to the rear surface, and a storage groove 7 in which a thin groove 6 is continuously provided is cut out from the rear side above the end face, and a coiled spring portion 9 of a torsion spring 8 is partially inserted in the storage groove 7 to the rear portion The beard 10 of the torsion spring 8 is stored in contact with the rear surface of the wall 5 and one of the mustaches 10 is attached to the rear wall 5.
The structure is characterized in that it is fitted to the back surface and the other beard 11 is inserted into the narrow groove 6 and locked.

[Operation] In the above description, the lid 1 is constantly urged in the opening direction by the urging force of the torsion spring 8 mounted on the hinge boss 2 at the rear end, but the lid 1 is closed and locked by the clasp at the front end. The lid does not open.

Here, when the stopper plate is unlocked, the lid 1 automatically opens upward due to the elastic force of the torsion spring 8, but in this case, a part of the coiled spring portion 9 of the torsion spring 8 causes the cosmetic dish 4 rear wall 5 to move.
Since the coiled spring portion 9 is loosened while sliding on the rear surface of the rear wall 5 at the time of opening the lid, the looseness is a slow movement due to frictional resistance even with sufficient elasticity. The opening operation of the lid 1 also moves slowly.

[Embodiment] An embodiment will be described below with reference to the drawings. In the present invention, a torsion spring 8 for driving the opening of the lid 1 is configured to act by slidingly contacting the rear surface of the rear wall 5 of the cosmetic tray 4 to provide sufficient elasticity. It is characterized in that the lid 1 is slowly opened while having the above.

In FIGS. 1 and 2, 4 is a drum filled with cosmetics 12.
Although not visible in this figure, the hinged boss is formed to project rearward from the left and right sides of the rear wall 5, which is a cosmetic plate containing 13
The lid 1 is a hinge boss 2 vertically extending from the center of the rear edge.
Is fitted between hinge bosses on both sides of the rear wall 5 of the cosmetic dish 4, pivotally attached by a hinge pin inserted into the hinge pin hole 3, and is provided on the upper surface of the cosmetic dish 4 such that it can be opened. 14 indicates a mirror.

Although not shown in the drawing, a stopper metal for locking the lid is formed between the cosmetic dish 4 and the front end portion of the lid 1, and a known push button for unlocking the stopper metal is provided if necessary.

Reference numeral 8 denotes a torsion spring for driving the lid 1 to open, which has a shape in which whiskers 10 and 11 for locking are provided at both ends of a coiled spring portion 9 wound several times, and one side of the hinge boss 2 on the lid 1 side. The side end surface of the is always equipped with the lid 1 for urging it in the opening direction.

That is, on the front side half surface including the hinge pin hole 3 on one side end surface of the hinge boss 2, the front side opens to the rear side of the cosmetic dish 4 rear wall 5, and the narrow side groove 6 is continuously provided above the surface from the rear side. 7 is cut out, and the coiled spring portion 9 of the torsion spring 8 is stored in the storage groove 7 by contacting a part of the coiled spring portion 9 with the rear surface of the rear wall 5, and the one beard 10 of the torsion spring 8 is stored in the rear surface of the rear wall 5. , The other beard 11 is inserted into and locked in the narrow groove 6 so that the torsion spring 8 stores energy when the lid 1 is closed.

Therefore, the torsion spring 8 constantly urges the lid 1 in the opening direction, and when the stopper plate is unlocked to release the restraint, the lid 1 is automatically opened upward by the torsion spring 8. in this case,
Since the coiled spring portion 9 is in sliding contact with the rear surface of the rear wall 5 of the cosmetic dish 4, the opening operation of the lid 1 is a slow movement.

“Effect of device” As described above, the lid 1 is included in the cosmetic compact of the present invention.
A lid driving torsion spring 8 which is provided on one side edge of the hinge boss 2 at the rear edge and which automatically opens the lid 1 upward when the stopper plate is unlocked is slid on the rear surface of the cosmetic plate 4 rear wall 5. Since the configuration is such that they act in contact with each other, the lid 1 can be slowly opened even if a sufficient elastic force is applied to the torsion spring 8, which is easy and convenient to handle.
