Abstract: A bottom for a paper cup is formed by advancing a punch against a paperboard web to push the web against a cutting edge which cuts out a circular cup bottom blank from the web. The punch is kept in a forward state to clamp an outer peripheral portion of the blank immovably against a surface of a sleeve. A reciprocable draw is advanced against a center portion of the blank to push the center portion into a circular opening of the sleeve while maintaining the clamping force, to cause the center portion of the blank to become stretched. The clamping force is then progressively released to permit the outer peripheral portion to enter the opening and become bent to form a lip extending at a substantially right angle. The lip is compressed within a gap formed between the draw and a surface of the opening. Because of the stretching of the blank, pleats formed in the lip are only in the form of micropleats that are flattened in a non-folded over state.

Abstract: The disclosure illustrates and describes a sterilization apparatus and method for sterilizing the interiors of paperboard containers, wherein such apparatus and method are effective through the mandrel assembly on which the container bottom closures are formed and sealed. This is accomplished by forming longitudinal channels through each mandrel and connecting same to separate compartments formed within the hub, and providing means for communicating a suitable sterilant fog through respective compartments and channels at the station where each bottom-formed container is stripped from its respective mandrel. The usual fast stripping action tends to create a vacuum within the container which aids the dispersement of the fog onto the entire inside surface of the container, sterilizing it prior to the subsequent filling operation.
