That is, a case cover for a tail lamp according to the present invention is provided with a color thin film of a predetermined color corresponding to the light projecting openings of a plurality of lamp cases and a surrounding of the lamp case on one side surface of a flexible synthetic resin sheet. When carrying out injection molding of a cover body common to the light projecting openings of a plurality of lamp cases and a case edging body around the cover body integrally with transparent molten resin while carrying a decorative thin film to be decorated with the edging In addition, the color thin film and the decorative thin film carried on the sheet are welded to a molten resin, and the sheet is peeled off after injection molding, and the color thin film is on the inner surface of the cover body and the decorative thin film is on the inner surface of the case edging body. The feature is that they are respectively transferred.

According to the above-mentioned characteristic construction, the case cover in which the surface portions corresponding to the light projecting openings of the plurality of lamp cases are colored in a predetermined shade by the color thin film, and the periphery thereof is framed by the decorative thin film, It is possible to obtain a single common article over the light projecting openings of a plurality of lamp cases.

Therefore, even if only one set of molds is used for resin molding the case cover for the light projecting openings of the plurality of lamp cases, and the manufacturer name, mark, model number, etc. are attached to the case cover, All you have to do is work on this set of molds. Alternatively, by making a part of the color thin film blank, it is possible to easily attach the manufacturer's name, mark, model number, etc. to the case cover.

Further, when the cover body and the case edging body are integrally injection-molded, since the color thin film and the decorative thin film carried on the synthetic resin sheet are transferred, these thin films are bordered by the cover body and the case edging body. It can be firmly held on the body. In addition to reducing the cost of the mold, the case edging body is molded at the same time as the injection molding of the case body for improving the design, so that the case cover provided with the case edging body can be obtained at low cost. it can.

Further, as a decorative thin film to be transferred to the inner surface of the case edging body, a thin film made of paint containing metal powder can be used to finish the case edging body in a metallic tone, or as a decorative thin film, for example, By making patterns such as fine floral patterns by printing etc., and coloring with various colors, and further, if necessary, including a decorative thin film with the above metal powder-containing paint, by appropriately combining these, The case edging body can be finished in a variety of variations with a high sense of accessories.
