Abstract
A method of making a photoflash article including a substrate member, a plurality (e.g., ten) of electrically-activated photoflash lamps, and a light-transmitting polymer covering which encapsulates each of the photoflash lamps and is also secured to the substrate member to define a unitary component. The substrate is produced by injection molding with each of the lamps subsequently positioned therein. This assembled component is then either placed within an injection mold apparatus and a predetermined quantity of thermoplastic or thermosetting resin injected therein to define the polymer member, or the polymer is added in liquid form to completely fill each of the substrate member's individual lamp-receiving compartments. The finished article is especially suited for forming part of a completed photoflash device further including circuitry and other items, such as described in the present art.
