Construction for securing a paper roll to a holder

摘要

Multiple embodiments of a construction for exerting a force substantially along the longitudinal axis of a roll of paper towels supported between two side arms of a paper towel holder. The longitudinal force urges the side arms outwardly toward their maximum deflection point to increase the stability of the holder. Each end of the constructions includes a cylindrical portion that fits over each bearing member of the side arms. The longitudinal force is created by either a spring inserted within the core of a roll of paper towels, or a bellows portion of the construction. Each bellows portion is made of a thermoplastic material having sufficient elastic properties to create the longitudinal forces.
