Abstract: A thin walled lid formed of a thermoplastic material having a generally circular center portion and an outer rim portion which fits over the cup bead and includes an integral peripheral skirt which makes up the outer side wall of the lid is disclosed. Located between the rim portion and the center portion is a recess or annular trough with an inner wall and an outer wall. The outer wall is separated into two shelves and three vertical sections. The lower shelf serves as a receiver ring upon which the lid above rests. The short vertical section located above the receiver ring effectively prevents any lateral movement of the lid above, while the lowest wall section forms the stacking ring and generally has a negative slope toward the lid skirt. Spaced periodically around the circumference of the stacking ring are positive draft flutes which have a positive slope away from the skirt and toward the center of the lid. The recess has a generally flat bottom which connects the stacking ring to the inner wall.

Abstract: A method and apparatus for pinch perforating multi-ply web material to increase the perforation ply bond and/or perforation ply bond retention by pinching the multiple plies of web material together and then perforating the material using an anvil and perforator blade design provided on a perforating apparatus. Specifically, the apparatus comprises a roll mounted contoured perforator blade which cooperates with a beveled anvil to produce perforation ply bonds perpendicular to the length of the multiple plies of web material. The desired anvil/perforator blade interface angle between 0.degree. and 20.degree. is provided by beveling the anvil. A 15.degree. beveled anvil is preferred to provide a 5.degree. anvil/perforator blade interface angle. By pinching and bonding the leading edges and other predetermined points of the multi-ply tissue paper together before cutting, the likelihood of ply separation, missing plies and ply mismatch is greatly reduced.
