ABSTRACT:
An internal to external self-buoyant straw system for the safe and sanitary removal of contents from aluminum can lift tab containers. The system includes a top straw component (14) cylindrical and hollow in fabrication which vertically slides within close tolerance over its hollow bottom straw component (16) whose lower end is angular cut (30) and held in continuous contact with the container's inner bottom. The top straw component continues its vertical ascent until its integrally fabricated buoyancy float (15) makes contact with the guidance ring (13) which keeps the top straw component directly positioned inline with the container's lid opening. The upper straw component (23) having reached drinking access level may now be angularly adjusted at the outer segmented straw portion (22) for ease of consumption of contents through the rolled lip end (28). Stability and appropriate positioning of the internal to external self-buoyant straw system within its container is accomplished by means of an articulated structure: holding frame (19) and holding frame arm (29) anchored to the underside of the container's lid at points (24A) and (24B) with the holding frame's lowermost end connected at point (18) to the bottom straw component, thusly causing the bottom straw component to remain stationary and in continuous contact with the container's innermost bottom. The all aluminum fabrication of the internal to external self-buoyant straw system allows for recycling within the aluminum can lift tab beverage container.
