  • Patent number: 5879693
    Abstract: Packaging an acne packet, which packet will hold just one three inch by three inch square acne pad is disclosed. The three inch square acne pad is folded in half twice to render the size of the acne pad one and one-half inches by one and one-half inches. The, folded pad is thereafter inserted by a packet forming machine utilizing MP3850 paper, foil, and poly carbonate to render the packaged pad ultimately three inches by two and three-quarters by one-eighth to one-quarter inch thick with twenty-two individual packets separated at their lateral edges and then placed in a box. The acne pad itself is 75 gram 149-189 tight waffle Novonette. Each pad is impregnated with 1.56 grams of the treatment solution. The method of forming the pads is to run the three inch ribbon of waffle Novonette through a feeding machine and thereafter dip the same in a solution having as its most active ingredient 0.5% salicylic acid. De-ionized water (75%) and SD Alcohol 40 (24%) make up the major portion of the inactive ingredient.
