Abstract
Abstract A package of collapsible tubes comprising a tray at top and bottom of a plurality of similarly oriented tubes arranged side by side in parallel alignment, each tube having a cap closing one end and the other end open, each tray having a plurality of indentations and corresponding protrusions, the caps of said tubes being in the indentations of the top tray and the protrusions on the bottom tray extending into the open ends of the tubes and giving support against accidental deformation in a radial direction, and means to retain the trays together against the ends of the tubes. Two or more assemblies are stacked in a carton with the protrusions of one assembly extending into the corresponding indentations of another assembly. The tray per se is also part of the invention.
