Compact, comprising a lid, a soft material packing is attached to the upper end of the side wall of the cosmetic storage dish, and a soft material packing that elastically contacts the packing is attached to the inner lid. adopt.

[0006] As an embodiment of the packing, the packing of the cosmetic storage dish and the inner lid is insert-molded with an elastomer, and as a specific shape, the packing at the upper end of the cosmetic storage dish is provided. It has a flat elastic contact surface, the packing of the inner lid is provided with two ridges on the inner side and the outer side, and the outer projections are raised high.

[0007]

Next, embodiments of the present invention will be described with reference to the drawings. 1 and 2, A is a case main body, B is a cosmetic storage dish, C is a middle lid, D is an opening / closing lid, and E is a puff. The case main body A is vertically provided from a bottom frame a1 having a bottom wall 1 and a side peripheral wall 2, a peripheral wall 3, an upper wall 4, a step wall 5, and a step wall 5 fitted to the side peripheral wall 2, and an inner periphery of the step wall 5. And an upper frame a2 having an inner wall 6. The outer shape of the upper frame a2 is a quadrilateral having front, rear, left and right sides with a circular arc at a corner.

A notch 7 is provided in the center of the rear side of the case body A, so that the hinge mechanism of the open / close lid D is accommodated. An opening / closing mechanism 8 for the opening / closing lid D is provided at the center of the front side facing the notch 7 of the case body A, and a hinge mechanism of the inner lid C is provided at the center of the upper wall 4 on the left side. Is formed, and the hinge pin is pivotally supported.

As shown in FIG. 5, a locking ring 10 is erected near the inner peripheral edge of the step wall 5, and between the inner wall of the inner wall 6 and the holding step 11 of the cosmetic storage tray B. Are formed.

[0010] As shown in FIGS.
Consists of a square bottom wall 12 and side walls 13 on each side,
Near the upper end of each side wall 13, a notch 14
A flange 17 provided with a protrusion protrudes from the outer surface of the side wall 13, through a notch 14 of the flange 15, a packing 17 reaching the upper end 16 of the side wall 13, and is formed on the outer periphery of each side wall 13 by insert molding. Glued.

The packing 17 is formed of a soft material such as an elastomer, and has a leg 18 supported by the flange 15 and an elastic contact portion 19 extending horizontally from the leg 18 inward and outward. The portion of the elastic contact portion 19 extending inward from the leg portion 18 elastically contacts the upper end 16 of the side wall 13 and locks the case body A from the peripheral edge of the outer horizontal portion 20 extending outward from the leg portion 18. A side wall 21 is provided so as to extend over the ring 10.

A projection 22 is provided inside the upper end 16 of each side wall 13 at a position lower than the upper end 16 with the groove interposed therebetween, and a locking ridge 23 is fitted to the projection 22.

As shown in FIG. 4, the inner lid C is formed by a square lid plate 30, and the center of the upper surface is a flat concave portion 31.
And a ridge 32 is provided upright on each side edge. On the left side of the cover plate 30, a hinge connecting piece 33 is continuously provided, and a finger hook 34 is provided on the right side opposite to the connecting piece 33, at the upper end of the ridge 32 so as to protrude. A pair of locking pieces 35 extending from the side of the plate 30 are provided.

On the front side of the cover plate 30, there is provided an engaging piece 36 for engaging with the opening / closing mechanism 8 of the case body A. A groove 37 is engraved on the lower surface of the cover plate 30 along the periphery, and a packing 38 made of an elastomer or other soft material is embedded in the groove 37 by insert molding.
The packing 38 is provided with protrusions 39a and 39b on the inside and outside, and the outside protrusion 39b is
Raised higher than a.

The connecting piece 33 is composed of two holding plates provided with a semicircular portion pivotally attached to the hinge pin, and a hinge mechanism is formed by fitting the hinge plate to the hinge pin.

As shown in FIGS. 1 and 2, the opening / closing lid D has a top wall 40 and four side walls 41 formed in a square shape corresponding to the main body case A and having a dish shape. Has a leg 42 for a hinge mechanism that is inserted into the cutout 7.

The leg 42 is pivotally supported by a hinge pin pivotally supported by the case body A, and the opening / closing lid D is urged in the opening direction by a spring. On the other side of the hinge mechanism,
A locking piece 43 having a hook at the lower end is vertically provided, and is engaged with an opening / closing mechanism 8 provided on the case body A. Top wall 40
A mirror 44 is mounted on the back surface of the device, and pressers 45a and 45b are suspended from a line passing through the center of the leg 42 and the locking piece 43.

As shown in FIG. 2, the opening / closing mechanism 8 includes a pressing portion 50 and a locking rod 51, and a spring portion 52 elastically mounted between the locking rod 51 and the spring receiver of the case body A. . A hook portion is provided outside the upper end of the locking rod 51 to engage with the locking piece 43 of the opening / closing lid D. Inside the step wall 5 of the case body A,
An engagement portion 54 is provided, which is guided by an engagement protrusion 53 provided on the outer peripheral edge of the head.

Next, the function and effect of the compact of the present invention will be described. When the compact opening / closing lid D is closed,
The locking piece 43 is engaged with the hook of the locking rod 51, and the pressers 45a and 45b of the opening / closing lid D push down the inner lid C, and the cosmetic storage tray B is sealed by the inner lid C. At that time, the packing 17 of the cosmetic storage tray B and the packing 38 of the inner lid C are engaged,
Keep the cosmetic storage tray B airtight.

When the packings 17 and 38 are engaged, the projection 39a of the packing 38 is pressed against the elastic contact portion on the leg 18 of the packing 17 as shown in FIG. The outer protrusion 39b presses the outer horizontal portion 20, but since the outer horizontal portion 20 can bend downward, both the protrusions 39b are pressed.
The a and 39b are evenly fitted into the packing 17, and the sealing property is extremely high.

When the lid D is opened, when the pressing portion 50 of the opening / closing mechanism 8 is pressed, the locking rod 51 and the locking piece 43 are disengaged, and the lid D is opened and closed by a spring force. At the same time, the engaging portion 54 pushes up the engaging piece 36 of the inner lid C, slightly opens the inner lid C, and creates a gap between the finger hooking portion 34 and the upper wall 4 of the case main body A for a fingertip to enter. Opening of the inner lid C is facilitated.

In the above-described embodiment, the specific configuration in which the external shape of the compact is square and the shape of the cosmetic storage dish and the inner lid is square is described. Is not limited to the embodiment.

[0023]

Since the present invention is configured as described above, it has the following effects. An elastomer or other soft material packing is attached to the cosmetic storage dish and the inner lid that covers the cosmetic storage dish, so that the soft material packing is elastically contacted with each other, so that the sealing property of the packing can be improved. did it.
Further, since the sealing can be performed with a small force, the strength of components such as the hinge mechanism and the opening / closing mechanism can be reduced.
