Abstract
A receptacle has at least one elastomeric sidewall with a contoured non-linear shape defining a container with a predetermined volume for housing a substance to be contained. The at least one sidewall includes a substance-contacting surface. The receptacle is fully reversibly eversible to transform between a first stable conformation with the substance-contacting surface facing inward and a second stable conformation with the substance-contacting surface facing outward allowing for facile cleaning and drying of the substance-contacting surface. The at least one elastomeric sidewall possesses sufficient structural strength to stand upright in the first and second stable conformations without extraneous support. The receptacle can include a cap and an attachment joint for securing the cap to the elastomeric receptacle.
