Abstract
An environmentally friendly system for delivering a potable liquid to a user, comprising a delivery tube having a cylindrical wall that defines a cylindrical annulus through which a potable liquid can flow. The cylindrical wall consists essentially of a solid potable material that is liquid at room temperature, wherein the wall is formed at a temperature below the freezing point of the potable material.
Claims9
An assembly for the manufacture of an environmentally friendly potable liquid delivery system, comprising:
- a cooling tube having a first end, a second end and an annular bore for retention of a potable material that is liquid at room temperature and solid when cooled to or below the freezing point of the potable material;
- a base affixed to a first end of the cooling tube for sealing the first end of the cooling tube;
- and
- a removable draw rod approximately concentrically positioned within the annular bore of the cooling tube.
The assembly of claim 2, further comprising a removable draw rod positioner secured to the draw rod and the second end of the cooling tube that positions an end of the draw rod approximately concentrically within the annular bore of the cooling tube.
A method for the manufacture of an environmentally friendly potable liquid delivery system, comprising:
- providing a cooling tube having a first end, a second end and an annular bore for retention of a potable material that is liquid at room temperature and is solid when cooled to or below the freezing point of the potable material, wherein a base is affixed to a first end of the cooling tube for sealing the first end of the cooling tube;
- positioning a removable draw rod approximately concentrically within the annular bore of the cooling tube;
- inserting into the annular bore of the cooling tube in a room temperature environment a potable material that is liquid in the room temperature environment and is solid when cooled to or below the freezing point of the potable material;
- exposing the assembly to a cold environment that freezes the potable material;
- removing the assembly from the cold environment to the room temperature environment;
- removing the frozen potable material from the cooling tube by pulling on the draw rod;
- and
- removing the draw rod from the frozen potable material to form a potable liquid delivery system.
