发明名称 Image bearing template for instant film packs
摘要 An image bearing template adapted for use with an exposure window of an instant film pack and being made up of a thin sheet and a pair of rigid strips. The thin sheet has a lateral dimension substantially the same as or less than the width of the exposure window, and a longitudinal dimension greater than the length of the exposure window. Each of the rigid strips has a length equal to or slightly less than the lateral dimensions of the window and extends laterally across the sheet so that upon insertion of the template within the film pack, the strips preclude movement of the template and stiffen the template so as to keep the sheet flat. The strips also serve to facilitate insertion and removal of the template by providing upstanding edges for grasping.
