ABSTRACT:
A method is provided of forming a multi-pack container assembly having at least four containers joined together by a cross or plus shaped frangible web. The method includes the steps of providing at least one male mold member and at least one female mold member, disposing the mold members so as to define at least four container cavities separated by a cross or plus shaped web cavity, injecting the cavities with a plastics material to form the multi-pack container assembly, and releasing the multi-pack container assembly from the mold members. Preferably, the method is used to form multi-peck containers, such as yogurt or pudding containers, where each individual container can be easily separated from the multi-pack container assembly.
