Partially plated plastic product

Abstract

A partially plated plastic product includes a first base member and a second base member that are made of different plastic materials. The first base member includes a first corner portion having a curved wall surface. The second base member includes a second corner portion. The first and second corner portions are located on a front side of the product. The first and second base members are adjacent to each other at least at the first corner portion and the second corner portion. Only one of the first and second base members includes a metal coating film formed on a region of an outer surface of the base member with which the other base member is not in contact. The second corner portion includes a groove forming portion. The groove forming portion forms a groove between itself and at least the curved wall surface of the first corner portion.

1 . A partially plated plastic product comprising a first base member and a second base member that are made of different plastic materials, wherein
 the first base member includes a first corner portion,   the second base member includes a second corner portion,   the first corner portion and the second corner portion are located on a front side of the partially plated plastic product,   the first base member and the second base member are adjacent to each other at least at the first corner portion and the second corner portion,   the first corner portion includes a convex curved wall surface,   only one of the first base member and the second base member includes a metal coating film formed on a region of an outer surface of the base member with which the other base member is not in contact, and   the second corner portion includes a groove forming portion that forms a groove between itself and at least the curved wall surface of the first corner portion.   
     
     
         2 . The partially plated plastic product according to  claim 1 , wherein a width of the groove decreases toward a deepest part of the groove. 
     
     
         3 . The partially plated plastic product according to  claim 2 , wherein
 part of a front side surface of the first base member that is adjacent to the first corner portion constitutes a general wall surface of the first base member,   the first corner portion includes an upright wall surface that extends from the curved wall surface in a direction intersecting with the general wall surface,   the groove forming portion includes an inclined wall surface that is inclined with respect to the upright wall surface such that, toward the front side, the inclined wall surface is inclined away from the first corner portion, and   the inclined wall surface is in contact with the upright wall surface.   
     
     
         4 . The partially plated plastic product according to  claim 3 , wherein, in the groove, the metal coating film is formed on the curved wall surface and part of the upright wall surface that faces the groove. 
     
     
         5 . The partially plated plastic product according to  claim 2 , wherein
 part of a front side surface of the first base member that is adjacent to the first corner portion constitutes a general wall surface of the first base member,   the first corner portion includes an upright wall surface that extends from the curved wall surface in a direction intersecting with the general wall surface,   the groove forming portion includes an inclined wall surface that is inclined with respect to the upright wall surface such that, toward the front side, the inclined wall surface is inclined away from the first corner portion,   the inclined wall surface is in contact with the curved wall surface, and   the groove is filled with part of the metal coating film.   
     
     
         6 . The partially plated plastic product according to  claim 3 , wherein
 part of a front side surface of the second base member that is adjacent to the second corner portion constitutes a general wall surface of the second base member, and   the general wall surface of the first base member and the general wall surface of the second base member are located on a same plane.   
     
     
         7 . The partially plated plastic product according to  claim 2 , wherein
 the groove forming portion includes an inclined wall surface that is inclined with respect to a front-back direction such that, toward the front side, the inclined wall surface is inclined away from the first corner portion,   the inclined wall surface is in contact with the curved wall surface,   in the groove, the metal coating film is formed at part of the curved wall surface that faces the groove,   part of the inclined wall surface that is in contact with the curved wall surface is an outer edge of the second corner portion,   a depth, which is a dimension in the front-back direction, to the outer edge from a most front side position on an outer surface of the second corner portion is set to a value in a range from 0.15 mm to 1.5 mm, and   an angle formed by the inclined wall surface with respect to the front-back direction is set to a value in a range from 5° to 15°.
