Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to an improvement of a case body used for storing small electrical equipment, cosmetics, etc.

(Prior Art) Conventionally, in this type of case body, when the upper surface of the body opening is closed with a lid, the respective edges 53 and 54 facing the pivoting portions of the body 51 and the lid 52 of the case body shown in FIG. Concave portions 55, 55 and convex portion 5 formed in
6 and 56, the lid 52 is prevented from being opened inadvertently. Here, the recess 5
5, 55 and the protrusions 56, 56 engage,
As shown in FIGS. 2a to 2c, when the convex portion 56 formed in an arc shape comes into pressure contact with the upper surface of the edge 53 of the body 51, the side surface of the lid 52 is elastically deformed outward, and the convex portion 56
When the body 51 reaches the concave portion 55, the convex portion 56 fits into the concave portion 55 with a sense of moderation due to the restoring force. However, in the case of a case body made of synthetic resin, the longer the length of the case body is, depending on the shape of the items to be stored, the more the opening, especially the edge part, suffers from heat shrinkage and temperature changes during molding, which is characteristic of resin. Therefore, in the case body with the above structure, the lid 52, which is hollow and has no stored items, will deform significantly in the width direction near the center of its edge 54, and the lid 52 side will be deformed in the width direction. If the convex parts 56, 56 do not fit properly with the concave parts 55, 55 on the body 51 side, the lid 52
The edge 54 of the lid 51 and the edge 53 of the body 51 no longer face each other accurately, and there is a risk that the lid 52 will not be able to be closed or will be opened inadvertently. In order to prevent this, it is conceivable to increase the thickness of the lid so that it is difficult to deform, but this would make the case body itself heavier and spoil its appearance.

(Purpose of the invention) In view of the above-mentioned problems, the present invention aims to prevent shrinkage of the edge of the lid.
The purpose is to effectively correct and prevent deformation and to enable smooth engagement between the body and the lid.

(Structure of the device) For this purpose, the present invention is a long box-shaped box for storing stored items, which is rotatably pivoted on one side edge of the long side of the box and closes the top surface of the opening of the box. A case body made of a lid made of plastic, and the lid can be opened and closed by engaging and removing a concave part formed on one of the edges facing the pivoting parts of the body and the lid, and a convex part on the other side. In this step, one end of the decorative plate that is to be tightly attached from the edge opposite to the pivot portion of the lid to the upper surface is engaged with approximately the center in the longitudinal direction of the edge of the lid,
The part of the decorative plate that is fixed to the lid is installed on the top surface of the lid, and the above-mentioned locking protrusion (recess) is formed on the edge of the lid.
is formed near the decorative plate.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

3 and 4 illustrate a storage case for an electric shaver. This storage case has a long box-shaped body.
and a long box-shaped lid 2 rotatably attached to one edge of the long side to close the top surface of the opening of the body 1,
A pallet 11 made of a press-molded plastic sheet is fitted and fixed to the body 1. The pallet 11 has a recess 1 in which a case body 13 with a reciprocating shaving blade block 12 attached thereto is housed in a horizontal position.
6 and a recess 15 for vertically storing the rotary shaving blade block 14 alone,
Furthermore, a recess 18 for storing a lint cleaning brush 17 is formed on the bottom surface of the case body storage recess 16.

In addition, the pivot part near the center of the lid 2 and the edge 2 facing each other
A decorative plate mounting groove 4 is formed from the side surface 2b to the top surface 2a, and a stepped protrusion 5 is provided on the surface of the mounting groove 4, and a claw portion 6 is formed on the edge 20. A decorative plate 3 is a substantially L-shaped plate that conforms to the outer shape of the cover from the side surface 2b to the top surface 2a and is mounted on the mounting groove 4. The mounting method is as shown in Figures 5 and 6, whereby a claw portion 6 provided on the edge of the mounting groove 4 is fitted into a hole 7 formed at one end of the decorative plate 3,
The decorative plate 3 is set in the mounting groove 4 so that the mounting hole 8 formed in the decorative plate 3 fits into the protrusion 5 using the insertion portion as a fulcrum, and the mounting plate 10 is fitted into a step 9 formed around the mounting hole 8 on the upper surface of the decorative plate 3. The lower surface of the mounting plate 10 is glued to the upper surface of the protrusion 5, thereby attaching the decorative plate 3 to the lid 2 by clamping it between the mounting groove 4 and the lower surface of the mounting plate 10.

That is, by adopting the above-mentioned mounting structure when attaching the plaque, even if the edge 20 of the lid 2 is bent inward due to heat shrinkage during molding, the plaque 3 can be attached. The side surface of the lid 2 that has been flexibly deformed by fixing the decorative plate 3 to the top surface 2a of the lid 2 with one end hooked to the claw portion 6 at the center of the edge 20 of the lid 2 where the amount of deformation is greatest. 2b
is forcibly corrected to its normal position by the decorative plate 3, and maintained in that state.
(Fig. 6) Convex portions 22, 22 for locking are formed near the decorative plate 3 on the edge 20 facing the pivot portion of the lid 2,
Further, the edge 19 of the body 1 facing the pivot portion is formed with recesses 21, 21 that engage with the projections 22, 22.

(Effect of the invention) Therefore, according to the invention having the above configuration,
The deformation in the width direction that occurs in the opening edge 20 of the lid 2 constituting the long box-shaped case body is actively restored and corrected to its normal position by the tensioning effect of attaching the decorative plate 3, and the deformation is ensured. By arranging the locking protrusion 22 (recess 21) near the corrected part (the center of the edge 20), the protrusion 22 (recess 21) on the lid 2 side and the body 1 side The concave part 21 (convex part 22) of the lid 2 can always be opposed to the body 1 without any error, and the lid 2 can be reliably closed on the body 1 with a comfortable sense of moderation.
