A form, fill and seal packaging machine having at least one multi-channel former therein for forming a pair of streams of three side sealed pouches. The at least one multi-channel former includes a shaped top and an open central forming area in which a strip of material brought to the former by a drive means from a roller is bent over and is then folded into a unique figure 8 or infinity sign, tubular configuration as it exits from the bottom. The unique configuration is then side sealed and cut into two tubular elements, which are then bottom sealed, filled, top sealed and cut-off in the machine to form two separate streams of three side sealed pouches. The machine may have a number of separate forming areas therein and the unique tubular configuration from which the pouches are formed is provided by the unique shaped top, open central and exit configurations of the formers, over and through, which the strip of material is bent and folded.

A packaging cup formed from a resilient material has an integrally body having a product reservoir and a lip. The product reservoir includes a flat bottom wall and a continuous side wall integrally joined together about a smooth curve. The side wall extends upwardly from the bottom wall to join the lip. The joint between the lip and the side wall continuously surrounds and defines an opening through the lip to the interior of the reservoir. The lip extends in a plane outwardly from this opening completely around the periphery of this opening. The bottom wall is essentially circular in shape and the opening is essentially squarish in shape. First, second, third and fourth fluted areas are located in the side wall at the corners of the squarish shaped opening. Each of the fluted areas is shaped essentially as a conical surface generated from a cone which is truncated by a plane about a parabolic intersecton of the plane with the cone. With the exception of the first, second, third and fourth fluted areas, the remainder of the side wall is formed as an essentially smooth, continuous surface.

This invention is directed to a segmented head seal for a cup packaging machine which has independent sealing head segments. The segmented head seal has a mounting plate having an insulator plate attached thereto. Attaching to the insulator plate is a support plate. Attached to the support plate are a plurality of locator assembly members. Movably linked to each individual locator assembly member is an independent sealing member. The links between the sealing members and the locator assembly members allow the sealing member to move on the locator assembly member. The locator assembly members are attached to the support plates with one or more bias springs located in openings in the locator assembly members between the support plate and the sealing blocks. The springs bias the sealing blocks away from the support plate whereby when the segmented head seal is utilized to seal cups on a cup packaging machine, the springs in association with the links between the locator assembly member and the sealing members, allow the sealing members to independently float and engage the cups being sealed.
