A device includes a base member that has inner and outer layers abutted thereagainst. An upper body extends upwardly from the base member and has a top end portion aligned about a longitudinal axis of the receptacle. The upper body has a deformably resilient outer surface including a plurality of coextensive pleats equidistantly spaced about a circumference of the upper body wherein longitudinal length of the pleats is greater than width of the pleats. Such pleats extend along a longitudinal length of the upper body and are simultaneously adaptable during operating conditions. The base member and the upper body are adaptable between compressed and expanded positions. The base member has a substantially cylindrical shape when adapted to an expanded position and the upper body has a spherical shape when adapted to an expanded position. Such an upper body has a circumference greater than the circumference of the base member.
