Abstract: This invention relates to a dispenser for paste-like products of the type having a container containing a product and closed at one end by a slidable piston in sealing engagement with the inner wall surface thereof, the other end being provided with a head member carrying on applicator and forming a pump chamber the volume of which is variable by the exertion of exterior pressure, the pump chamber being closed towards said container by a first check valve adapted to open only towards the pump chamber, and towards the outlet of the applicator by a second check valve adapted to open only towards said outlet.

Abstract: This invention relates to a container having a reservoir for storing a liquid and an intermediate storage space communicating with said reservoir and adapted to receive liquid therefrom on generation of a vacuum therein. Communication between reservoir and intermediate storage space is through a capillary tube having an inside diameter small enough so that a column of liquid is maintained therein whenever pressures in said reservoir and storage space are substantially equal, but large enough so that liquid flows into the storage space when pressure therein is lower than in the reservoir. The closure for the container comprises a piston which, as the container is opened, moves out of the storage space to create a vacuum therein.

Abstract: A plastic lid closure assembly for containers, particularly for packaging purposes, comprising a lid and a lid carrier connected to one another by an integral web hinge, the lid carrier being formed with an upstanding resilient tongue and the lid being formed with a cam or the like adjacent the hinge and operative to transversely deform the resilient tongue on movement of the lid to produce a snap-up effect.
