  • Containment with internal seal and method for manufacture thereof
    Patent number: 12162660
    Abstract: The present disclosure concerns a containment of pulp material that reduces reliance on adhesives and polymers. The containment is of two preformed semi-cylinders that linked together by using a preformed raised ridge that slots into a trough on the opposing half. The containment may optionally include a biopolymer based internal layer to provide a sealed containment. The present disclosure also concerns a cap for the containment with a narrowed wall and a recess to retain a lid liner with notched walls that allow for expansion at the closed end.
