Abstract: A corrugated container consisting mainly of a lower tray with upright peripheral flanges, upright liner tubes disposed side-by-side on the tray to form a pair of material-receiving chambers, and a surrounding outer shell or tube enclosing the liner tubes, the tubes being interlocked with the tray for maximum strength. A side-dispensing arrangement is provided which includes outwardly-displaceable tabs in the respective liner side walls, outer tube side wall, and flanges of the tray, whereby it is possible, when desired, to form a dispensing passage leading laterally from the lower ends of the material chambers.

Abstract: An end structure for a container body which is of tubular form and of multisided polygonal transverse cross section. It comprises a flat substantially disc-like end with attaching flanges hinged thereto and extending inwardly from the plane thereof, being in number equal to the sides of the body and substantially equal in lateral extent. The attaching flanges are hinged to the disc-like end by an arrangement which permits the end structure to be fitted into position within or exteriorly of the tubular container body and to be fastened in position by means of the attaching flanges.

Abstract: A self-sealing dispensing valve for use on various containers. It is a simple two-piece device consisting of an outer housing having a dispensing outlet and an inner complemental valve member which ordinarily closes the outlet but which can be moved by finger pressure to open the outlet, and which will automatically return to its closed position when opening pressure is released. The housing has a flexible dome-shaped outer wall which embraces and is attached to a complemental dome-shaped rigid wall at the outer end of the valve member, which also has an axially inwardly extending flared sealing skirt. The skirt normally seats on the outlet, which extends radially through the correspondially tapered housing, but will be displaced axially inwardly to open the outlet, upon inward axial pressure on the outer dome-shaped flexible housing wall. Internal container pressure aids in the normal seating of the valve member.
