A container is made of a substantially flexible material. A circumferentially extending array of longitudinally extending teeth are carried by the container and spaced from each other by recesses of a shape proportioned to receive identically-shaped teeth of an adjacent container of similar shape. The teeth each define a transversely enlarged, radially outer portion relation to a radially inner portion. The portions are proportioned to permit snap-fit, locking engagement of a tooth of the container between a pair of teeth of the adjacent container of similar shape.

In a molded container made of substantially flexible material, the improvement comprising in combination: an integrally molded component of said container comprising a circumferentially extending array of longitudinally extending teeth which are spaced from each other by recesses of a shape proportioned to receive identically-shaped teeth of an adjacent container of similar shape, said recess each defining a radially recessed bottom surface and said teeth each defining a radially projecting top surface; said container also defining a circumferential flange substantially continuously extending across one longitudinal end of each of said teeth, said flange defining an outermost circumferentially extending surface which occupies a radial level which is between the radial levels of the bottom surfaces and the top surfaces, whereby the interengaging teeth and recesses of said container and another, identical container cannot move longitudinally, said teeth each defining in cross section a generally arrowhead-shaped, transversely enlarged, radially outer portion relative to a radially inner portion, said portions being proportioned to permit snap-fit, locking engagement of a tooth of said container between a pair of teeth of said adjacent container of similar shape.
