Abstract
A multiple-compartment container is formed from an elongated sleeve of flexible material. Opposing end portions of the sleeve are respectively sealed together. A third seal of the walls of the sleeve, at a location spaced between those end portions, defines first and second hollow compartments respectively on each side of that third seal. The third seal is effected by a twisting of the sleeve about its longitudinal axis. There is illustrated a still further and preferred fourth seal at a location spaced between the third seal and one of the end portions so as to define a still further hollow compartment, and that additional seal also is effected by a twisting of the sleeve.
