Abstract: A collapsible tube assembly comprises a flexible tubular body of ductile metal, plastic or a lamination thereof, and a dispensing head structure of relatively stiff solid non-metallic plastic comprising inner and outer nested elements each having an annular shoulder and an annular longitudinal skirt, an annular end region of the body being inwardly turned to be clamped longitudinally between said shoulders and an adjacent annular portion of the body being frictionally radially clamped between the skirts.

Abstract: A collapsible container comprises a flexible walled tubular body having a heat sealed longitudinal seam, an integral preformed non-metallic thermoplastic head member having an annular skirt telescoped and heat sealed within an end of the tube body, and an external skirt on the head member surrounding the outer side of the tube body around the heat sealed region.

Abstract: This invention relates to an integrally molded captive cap assembly including a threaded base for attachment to a container and a lead tube which projects into a hollow cap which is pivotally connected to the base. An integrally molded pair of spring members are disposed between the cap and the base and have end portions pivotally connected to the base and to the cap. The spring members bias the cap toward one of two positions. When the cap is in a closed position, the spring members bias the cap toward the closed position and when the cap is opened past an intermediate position, the spring members bias the cap toward an open position.
