Claim:
1. A receptacle for containing a substance comprising: at least one sidewall defining a container with a predetermined volume for housing the substance to be contained, the container having an open end and an end wall opposing the open end, the at least one sidewall including a first substance-contacting surface, the container being reversibly eversible, such that the container reversibly transforms between a first stable conformation with the substance-contacting surface facing inward and a second stable conformation with the substance-contacting surface facing outward; and a rigid sleeve having a top and a bottom, the bottom having a bottom edge surface that defines an opening in the rigid sleeve, the rigid sleeve at least partially sheathing the container and having at least one sidewall-pull-down cutout surface defining a sidewall-pulldown cutout, wherein the sidewall-pull-down cutout surface extends from the bottom edge surface of the rigid sleeve and toward the top allowing for a second surface of the sidewall to be exposed when in the first stable conformation, wherein the at least one sidewall can be accessed during eversion to facilitate interaction of the at least one sidewall with respect to the rigid sleeve; wherein the at least one sidewall further includes at least one annular protrusion extending outward at least partially along the second surface of the sidewall at a location closer to the end wall than the open end; the receptacle further comprising a decoupling ledge formed into the rigid sleeve, while in the normal stable conformation the annular protrusion of the container cooperates with the decoupling ledge of the rigid sleeve defining a buckle region between the annular protrusion and the end wall to facilitate deformation during eversion of the container.
