    Publication number: 20240217688
    Abstract: A container (100) is formed by being folded and sealed on one of a multiplicity of male dies (12) of an apparatus (10). The male die (12) with the container (100) placed thereon is inserted into a female die (120). The female die (120) retains the container (100) while the male die (12) is removed therefrom. Lips (110-112) of the container (100) are sandwiched against the female die (120) while product is pushed thereon to prevent collapse of the container (100). The multiplicity of male dies (12) are relatively moveable by rotating about an axis (20) relative to the female die (120).
