Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact resin container in which a mirror is attached to the inner surface of a lid. It relates to an excellent compact container. [0002] Compact containers for storing cosmetics and the like are:
The inner surface of the lid is formed flat, and the mirror is fixed using a double-sided tape or the like with the flat surface as an adhesive surface. On the other hand, in the modern age where the unique appearance of the container is required for product differentiation and product concept, the outer surface of the lid is designed in various shapes, and part or the whole becomes a thick lid There are cases. [0003] However, a molded product injection-molded with a synthetic resin shrinks when cooled after injection molding, and the distribution of the amount of shrinkage and the residual stress caused by the shrinkage is reduced. Deviation occurs, causing sink marks, burrs or warpage. In particular, the greater the thickness of the molded product, the greater the effect and the more likely it is to cause deformation. Therefore, in the case of a lid having a part or the whole thickness as described above, the outer surface of the lid is liable to be shrunk or shrunk, and the intended appearance is difficult to appear, which is also a problem in design, and furthermore, warpage occurs. In this case, inconsistency occurs in the alignment with the container body, and the lid does not close properly or it becomes difficult to open, which causes inconvenience in function.
In addition, the adhesive surface of the mirror to be attached to the inner surface of the lid must be formed flat. There were many. SUMMARY OF THE INVENTION It is an object of the present invention to provide a compact container in which the lid of a resin-made compact container is hardly warped, sinked, and burred, and a mold can be easily manufactured. SUMMARY OF THE INVENTION The present invention is a resin compact container in which a mirror is attached to the inner surface of a lid, wherein a thinner portion is formed on the inner surface of the lid to reduce the thickness of the lid. In addition, a plurality of ribs that do not intersect each other are provided upright, and the above-mentioned problem is solved as a compact container characterized in that the mirror comes into contact with and is supported by all the ribs on the back surface. A meat relief is formed inside the lid of the compact container to reduce the thickness of the lid, and a plurality of ribs are provided to secure a mirror mounting plane. Since the plurality of ribs do not cross each other and are independent, a thick portion cannot be formed,
Hardly affected by shrinkage deformation of synthetic resin. On the other hand, since the ribs secure the mirror bonding plane and support it, even if the height of some of the ribs does not match during the manufacture of the mold and the bonding surface cannot be secured, the height is high. Only the part of the ribs that do not fit needs to be modified and corrected in a point-wise manner, and efficient mold production can be performed. An embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1A is a side sectional view of a compact container, and FIG. 1B is a plan view of an inner surface of a lid of the compact container. The compact container 1 is a container for holding cosmetics such as a foundation, has a substantially square shape in a plane, and is composed of a container body 2 and a lid 3. The lid 3 is attached to one end of the container body 2 using a pin 11,
It is hinged so that it can be opened and closed freely with 1 as a fulcrum. An engagement projection 21 is formed integrally with the other end of the container body 2. By utilizing the flexibility of the resin material of the engaging projections 21 to engage with the engaging claw pieces 31 formed on the lid 3, the lid and the main body are fitted. On the other hand, the engagement protrusion 2
The container 1 can be opened by releasing the meshing by pressing the button following the button 1 and lifting the lid 3. [0011] The container body 2 is provided with a wide storage section 6 for filling with cosmetics. A mirror 5 is provided on the inner surface of the lid 3.
Is attached. The inner surface of the lid 3 is depressed so as to have the same curved surface as that of the outer surface to form a meat relief 7, and the lid 3 is designed to have a constant thickness. That is, the outer surface of the lid 3 has a curved surface bulging so that the central portion is higher, and the inner surface of the lid 3 is also formed to have a curved surface that is depressed inward so as to conform to the curved surface. A plurality of short rectangular ribs 4A are erected in the meat escape portion 7 in a lattice shape. These ribs 4A do not intersect with each other and are integrally formed with the lid 3 independently. The top end of the rib 4A is located on the same plane,
Are formed. That is, the mirror 5 contacts and is supported by all the ribs 4A on the back surface. Mirror 5
Is attached using double-sided tape 8. For this reason, when manufacturing the mold of the lid 3, even if the height of some of the ribs 4A is not uniform due to warpage or deformation, the height of only the defective rib 4A is extended, or This can be adjusted easily by shaving. Also, when attaching the mirror 5, a large force is applied to the double-sided tape 8 in a point manner, and the ribs 4A can be made to be hard on the surface of the double-sided tape 8, so that the connection between the two can be ensured. . Next, other examples of the shape of the rib will be described with reference to FIGS. FIG. 2A shows a short rectangular rib 4B.
Are arranged in a T-shape. In FIG. 4B, short rectangular ribs 4C are arranged obliquely and radially arranged in groups of four. In the lid 3 in FIG. 3C, a plurality of pin-shaped ribs 4D are arranged at predetermined intervals. The lid 3 shown in FIG. 3D has a plurality of small circular ribs 4E arranged side by side, and FIG. 4E shows a plurality of circular ribs 4F having different diameters arranged concentrically. It is. Further, FIG. 4F shows a short rectangular rib 4G2 arranged in a lattice shape in a direction orthogonal to the ribs 4G1 of the protrusions. In any case, each of the ribs 4B to 4G is independent and does not intersect or contact with other ribs. As described above, depending on the compact container of the present invention, the thickness of the lid can be reduced irrespective of the design, so that the material of the compact container can be saved and the weight can be reduced. be able to. Further, a rib is projected from the inner surface of the lid to support and attach the mirror. However, since the plurality of ribs do not cross each other and are independent of each other, they are hardly affected by shrinkage and deformation of the synthetic resin. A compact container excellent in appearance can be obtained by preventing warping, sinking, and shading. Further, the molded product may be warped, and it may be difficult to obtain the mirror mounting plane. However, depending on the compact container of the present invention, only the defective rib is partially extended to adjust the rib. Then, the mirror mounting plane can be easily obtained.
