Abstract
The invention described herein relates to reservoirs within appliances. The present invention includes a reservoir made of a length of reservoir tubing. In particular embodiments, the length of the reservoir tubing is formed in an overlapping circular portion and conforms to the available space requirements within an appliance. Particular embodiments of the present invention include reservoirs, reservoir systems including a reservoir, processes for forming a reservoir, and processes for forming the aforementioned reservoir systems.

A reservoir comprising:
- a reservoir tube having a first tube end, a second tube end and a tube length wherein the first tube end is orientated opposite the second tube end along the tube length;
- one or more securing structures wherein the securing structures maintain the tube length of the reservoir tube in an overlapping circular portion, the overlapping circular portion comprising:
- a first reservoir tube layer including a substantial first circle having a circumference, and
- a second reservoir tube layer including a substantial first circle having a circumference,
- wherein the circumference of the substantial first circle of the second reservoir tube layer is greater than the circumference of the substantial first circle of the first reservoir tube layer;
- a first tube extension extending from the overlapping circular portion to the first tube end;
- and
- a second tube extension extending from the overlapping circular portion to the second tube end.
A process for forming a reservoir comprising the steps of:
- engaging a reservoir tube at an engagement point adjacent a first end of the reservoir tube where the reservoir tube includes:
- the first tube end, a second tube end, and a tube length wherein the first tube end is orientated opposite the second tube end along the tube length;
- one or more securing structures wherein the securing structures maintain the tube length of the reservoir tube in an overlapping circular portion,
- a first tube extension extending from the overlapping circular portion to the first tube end,
- a second tube extension extending from the overlapping circular portion to the second tube end, and
- a first overmolded attachment piece overmolded onto the first tube end and a second overmolded attachment piece overmolded onto the second tube end;
- driving the engagement point about a first circumference forming a substantial first circle with at least a portion of the length of the reservoir tube;
- applying tension to the length of the reservoir tube to force the length of the reservoir tube into a configuration about the first circumference wherein at least a portion of the length of the reservoir tube forms a substantial second circle adjacent the first circle;
- repeating the steps of driving and applying tension to form a first reservoir tube layer extending a width of a reservoir;
- returning at least a portion of the length of the reservoir tube and forming a second reservoir tube layer extending a second width of the reservoir using the same steps for forming the first reservoir tube layer at a second circumference;
- securing the length of the reservoir tube forming the multiple reservoir tube layers into the overlapping circular portion using one or more securing structures.
