(54) Blister-pack and process for its production


(57) A blister pack comprises a plastic trough projecting from a window-like cut out in a frame. The frame has at least two lateral support sections at an angle to the outer periphery of the frame. The plastic only covers the frame as far as the junction of the lateral support sections thus saving plastic when compared with known blister packs and facilitating mould release in manufacture.
