Double-walled articles for receiving decorative filler materials

A decorative double-walled vessel, comprising:

• an inner form defining a receptacle having a sidewall with an inner surface and an outer surface;
• an outer form having a sidewall with an inner surface and an outer surface, and wherein the outer form is spaced apart from the inner form to create a cavity between the outer surfaces of the inner form and the inner surfaces of the outer form;
• a bottom opening in the outer form enabling solid decorative filler materials to be introduced into the cavity such that the decorative materials do not enter into the receptacle;
• wherein the outer form bulges outwardly between an upper portion and the bottom opening to define an outermost outer surface;
• wherein the bottom opening defines a downwardly extending circular rim having a convex outer surface and a concave inner surface;
• a vessel base having an outer sidewall, an upper portion and a bottom surface adapted to rest against a support surface;
• the upper portion of the vessel base including a continuous circular groove with inner and outer opposing sidewalls configured to receive the rim of the vessel such that the inner sidewall of the of the base makes contact continuous with the concave inner surface of the rim and the outer sidewall of the base makes continuous contact with the convex outer surface of the rim;
• wherein the downwardly extending circular rim of the vessel is cylindrical in shape, and wherein the cylindrical rim is inserted directly into the continuous circular groove of the vessel base;
• wherein at least one of the inner and outer surfaces of the base includes at least one compressible, resilient corrugation so as to provide a watertight seal when the rim is inserted into the groove;
• and
• wherein the outer sidewall of the vessel base defines a diameter that is smaller than the outermost outer surface of the outer form.
