  • Patent number: 4840291
    Abstract: The container dispenser comprises a body member, a collar and a container biasing spring for initially receiving a column of nested containers and continuously exerting a biasing force on the containers, such that the last container of the column is disposed at the open end of the dispensing apparatus. The body member is preferrably made of a plastic material formed by extrusion blow molding or injection blow molding and in a further aspect of the invention, the collar is injection molded and secured to the body member by a snap fit or spin weld joining technique. The exterior of the body member is shaped to provide a number of inward depression adjacent the open end of the body member, for engaging the lower most containers of the stack of nested containers. Loading and/or dispensing of containers requires a localized resilient deformation as the containers move past the inward depressions.
