Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a cosmetic compact.

[Background Art] A container body for accommodating cosmetics and a rear part of a lid closing an upper surface of the container body are pivotally attached to each other, and a hook attached to a front part of the lid is attached to a front outer surface of the container body. 2. Description of the Related Art A cosmetic compact that is engaged with a lower surface of an engaging ridge is widely known.

"Problem to be Solved by the Invention" In the conventional compact described above, if there is a slight molding error in the container body or the lid, the engagement between the hook of the lid and the engaging ridge of the container body becomes too hard or loose. Therefore, the molding accuracy is strictly required, and the structure is slightly complicated, so that the cost is increased.

The present invention is provided so that the structure is simple and can be manufactured easily and inexpensively.

Means for Solving the Problems The bottom wall 3 and the rear part of the cover plate 7, each of which has a rectangular shape in a plane, are integrally connected to each other by an elastic wall part 6 extending rearward in an arc-shaped cross section, and a lower end of the elastic wall part. And the first thin hinge 4
And, the second thin hinge 5 is provided in the middle of the elastic wall portion 6 in the vertical direction,
The exterior body 1 provided sideways, and the side plates 10 and 10 respectively closing the left and right side surfaces of the exterior body
The pin shafts 1 are located above the rear ends of the
An inner body 2 pivotally attached at 1,11 and provided with a gap between a rear surface of a cosmetic storage dish 9 formed in a lower half between the side plates 10 and 10 and a lower half of an inner surface of the elastic wall portion 6; A distance between the first thin hinge 4 and the second thin hinge 5 and a distance between the axis of the pin shafts 11 and 11 and the second thin hinge 5 are substantially the same; The front and rear sides of the imaginary arc a centered on the first thin hinge 4 and passing through the second thin hinge 5 and the imaginary arc a 'centered on the axis of the pin shafts 11 and 11 and passing through the second thin hinge 5 The distance from the second thin hinge 5 to the upper end of the rear surface of the cosmetic storage tray 9 is at least substantially equal to the distance between the intersections B and B '.

[Operation] The distance between the first thin hinge 4 and the second thin hinge 5 and the distance between the axis of the pin shafts 11 and 11 and the second thin hinge 5 are substantially the same. An imaginary arc a centered on the one thin hinge 4 and passing through the second thin hinge 5 and an imaginary arc a 'centered on the axis of the pin shafts 11 and 11 and passing through the second thin hinge 5 both before and after the intersection point Since the distance between b and b 'and the distance from the second thin hinge 5 to the upper end of the rear face of the cosmetic storage tray 9 are at least substantially the same, the front portion of the lid plate 7 is inclined from the state shown in FIG. When lifted upward and backward, the elastic wall portion 6 is bent and deformed, and the second thin hinge 5 is bent.
Moves between the virtual arc A and the virtual arc A 'to a point B' where the two virtual arcs intersect, and the elastic wall portion 6 moves forward as shown by the imaginary line in FIG. Since the cover plate 7 is elastically inverted, the cover plate 7 is stabilized in the open state. When the front portion of the cover plate 7 is tilted forward from this state, the elastic wall portion 6 is bent and deformed, and the second thin hinge 5 passes between the two virtual arcs A and A ', and these virtual arcs are formed. Move to the other point (b) where it intersects, and the elastic wall portion 6 elastically inverts backward, so that the lid plate 7 is closed.

"Example" The compact according to the present invention is composed of two members, an exterior body 1 and an interior body 2, and the exterior body 1 has a bottom wall 3 having a planar rectangular shape.
And a rear part of the cover plate 7 is integrally continuous by an elastic wall portion 6 extending rearward in an arc-shaped cross section, and a first thin hinge 4 is provided at a lower end of the elastic wall portion, and at a middle of the elastic wall portion 6 in a vertical direction. The second thin hinges 5 are provided horizontally, and pin shafts 11 and 11 are attached to the outer surface of a pivotal attachment plate vertically suspended from both left and right rear portions of the cover plate 7. The distance between the two thin hinges 5 and the distance between the first thin hinge 4 and the second thin hinge 5 are substantially the same, and the engagement cylinder 12 that rises from the center of the bottom wall 3 is formed. A ridge is provided around the upper part of the inner surface, and the front part of the bottom wall 3 is curved upward and the front part of the cover plate 7 is curved downward.

The inner body 2 includes side plates 10, 10 on the left and right sides of the outer body 1.
The pin shafts 11, 11 are pivotally mounted in bearing holes 15, 15 drilled above the rear ends of the side plates, respectively, and the lower half between the side plates 10, 10 is provided. Forming a cosmetic storage plate 9 having a central portion having a concave portion 8 for storing the drum 14,
The upper surface of the projection 16 attached to the lower end of the outer surface of the side wall of the recess 8 is engaged with the lower surface of the ridge of the engaging cylinder 12. Further, a gap is provided between the rear surface of the cosmetic storage tray 9 and the lower half of the inner surface of the elastic wall portion 6, and a virtual arc a passing through the first thin hinge 4 and passing through the second thin hinge 5 is provided. , Pin shaft 1 above
The distance between the front and rear intersections, b and b ', which intersect the imaginary arc i' passing through the second thin hinge 5 about the axes of the axes 11 and 11;
The distance from the second thin hinge 5 to the upper end of the rear surface of the cosmetic storage tray 9 is at least substantially equal.

13 is a mirror attached to the lower surface of the cover plate 7 of the exterior body 1,
Provided as needed.

[Effects of the Invention] The present invention has the above configuration. The compact of the present invention is composed of an exterior body 1 in which each rear portion of a bottom wall 3 and a cover plate 7 is integrally connected by an elastic wall portion 6 and a left and right side of the exterior body. The upper portions of the rear ends of the side plates 10 and 10 closing the both side surfaces are pivotally attached to the upper right and left portions of the elastic wall portion 6 by pin shafts 11 and 11, respectively.
Since it is formed with the interior body 2 in which the cosmetic storage tray 9 is formed in the lower half between 10, the number of constituent members is small, the structure of each member is simple, and the member can be formed at low cost.

Further, the distance between the first thin hinge 4 and the second thin hinge 5 and the distance from the axis of the pin shafts 11 and 11 to the second thin hinge 5
The distance between the cosmetic storage tray 9 and the cosmetic storage tray 9 is substantially the same.
A gap is provided between the rear surface and the lower half of the inner surface of the elastic wall portion 6, an imaginary arc b centering on the first thin hinge 4 and passing through the second thin hinge 5, and the axis of the pin shafts 11, 11 At least approximately the distance between the front and rear intersections b and b 'where the imaginary arc a ′ passing through the second thin hinge 5 and passing through the second thin hinge 5 and the distance from the second thin hinge 5 to the upper end of the rear surface of the cosmetic storage tray 9 are at least approximately. When the front portion of the cover plate 7 is lifted obliquely upward and rearward from the state shown in FIG. 1, the second thin hinge 5 passes between the virtual arcs A and A ′, and these virtual arcs are formed. It moves to the intersecting intersection b ', and the elastic wall portion 6 is elastically inverted forward as shown by the imaginary line in FIG. 1, so that the open state can be stably held, and When the lid plate 7 is tilted forward from this state, the second thin hinge 5 passes between the virtual arcs A and A '. Te, which like move to the other point of intersection B 'virtual circle intersect, and the elastic wall 6 will be elastically reversed backward, thus, it is possible to stably hold the lid closed.
