    Abstract: A receptacle includes an upper portion having a cylindrical portion and an open end and a lower portion depending from the upper portion, where the lower portion is tapered and has a closed bottom end. The receptacle may include a radially-extending annular ring with a flat or sloped bottom surface and disposed on an outer surface of the receptacle at a transition between the upper portion and the lower portion and/or a radially-projecting lip circumscribing the open end, which may be configured for inter-locking engagement with a mated cap inserted into the open end of the upper portion. Embodiments may include one or more longitudinally-oriented grooves formed in an inner surface of the upper portion. The receptacle may be a unitary plastic structure.
