Abstract: A device is disclosed for containing and dispensing flowable materials contained in a material handling unit which is located at least in part within an outer container. The material handling unit includes a first, relatively rigid portion having a nozzle affixed to one end thereof and a readily reshapable bladder affixed to the other end thereof, with the nozzle having a one-way check valve permitting ejection of the contents therefrom. The outer container admits air into the space between the containers to thereby cause selective expellation of the contents of the material handling unit without direct manual contact by a user with the device.

Abstract: A device is disclosed for containing and dispensing flowable materials contained in an inner container which is located within an outer container. The inner container includes a first portion having a nozzle affixed to one end thereof and a readily reshapable bladder affixed to the other end thereof, with the nozzle having a first one-way check valve permitting ejection of the contents from the inner container. The outer container has a second one-way valve to admit air from the exterior of the device to the space between the inner and outer containers and a compressible volume reducing structure for reducing the volume of the outer container without direct contact by a user with the volume reducing structure.

Abstract: Apparatus for dispensing fluid materials contained in a readily deformable inner container which is located within a resilient outer container. The inner container and a nozzle are permanently affixed to one another and the nozzle has a first one-way check valve permitting ejection of the contents from the inner container. The resilient outer container has a second one-way valve to admit air from the exterior of the device to the space between the inner and outer containers.

Abstract: Apparatus for dispensing flowable, usually fluid, material contained in a bladder, the apparatus comprising an exterior resilient container adapted to receive and secure the bladder, the exterior container including a first one-way check valve communicating with the interior of the bladder and positioned to permit flow of the contents of the bladder to the exterior of the apparatus, and a second one-way check valve positioned to permit air to flow between the container and bladder. Preferably, the container includes a cap portion removable from the body portion of the container proper, and comprising a probe adapted to pierce and seal with the bladder when the cap portion of the container is secured to the body portion with the bladder disposed for engagement of and securing by annular surfaces defined on the body portion and the cap portion.
