ABSTRACT:
The protective plastic cover component of a compact multiflash unit that integrally-formed prisms on its side walls is fastened to the base component by overlying adhesive strips of clear plastic material. The cover and base components are thus securely locked in operative relationship with one another without the application of heat or ultrasonic energy which could distort the prismatic light-focusing side walls of the cover and alter their optical characteristics. In mechanically-ignitable type flash units the potential danger of accidentally firing the flashlamps by heating or vibrating the percussive ignition material on the anvils during the joining operation is also avoided.
