Claim:
Separable two-component drinking systems for facilitating the separation, stacking and storing of pluralities of components of drinking vessels including yards of ale comprising, in combination: an upper component having an upper end and a lower end with an inwardly tapering concave side wall there between, the upper component having a cylindrical lower axial extension at its lower end, the upper component and the lower axial extension adapted to receive a drink for consumption by a user, the side wall and the lower extension having a common central axis, the side wall having a lower end with the lower extension joining to form a shoulder, the side wall having a continuous curve along its length with the upper end having a diameter greater than the lower end and with a tangent of the side wall being closer to perpendicular to the central axis the closer to the upper end and with a tangent of the side wall being closer to parallel to the central axis the closer to the lower end; and a lower component having an upper end and a lower end with a generally annular lateral extension there between, the upper end of the lower component having an upper aperture with a diameter essentially equal to the diameter of the axial extension for the receipt of the axial extension during use, the lower end of the lower component having a lower aperture with a diameter greater than the diameter of the upper aperture, the lower component having a passageway there through with the upper aperture forming a top of the passageway and the lower aperture forming a bottom of the aperture, the upper aperture adapted to receive the axial extension up to the shoulder, the system including the lower component and the upper component sharing the same common central axis when coupled for use, the width of the system varies from about one fifth to one eighteenth of its height, the heights being measure axially along the length of the central axis, and a plurality of upper components adapted to have their lower ends received within the upper ends of adjacent upper components one within another for stacking purposes as for storage and transportation and a plurality of lower components adapted to have their upper ends received within the lower ends of adjacent lower components one within another for stacking storage and transportation.
