Abstract: A holder for a replaceable container of product includes a wall mountable support member having a longitudinal dimension. A holding sleeve extends transversely to the longitudinal dimension a first distance from a first region of the support member. The holding sleeve defines a bulbous recess. A foot extends transversely to the longitudinal dimension a second distance from a second region of the support member. The second distance is less than the first distance. The foot is spaced from the holding sleeve.

Abstract: Apparatus for placing contents of a first container in fluid communication with a delivery apparatus includes an actuating element carried by the delivery apparatus and a valve element carried by the first container. At least one of the actuating element and the valve element defines a flow path from the first container to the delivery apparatus when the actuating element and the valve element are engaged with one another. The actuating element is engageable with a circular cylindrical valve of a second container to prevent flow of contents of the second container into the delivery apparatus.
