Fluid dispenser

A method of using a fluid dispenser for manually applying a selected fluid to a desired location, comprising the steps of:

• (a) providing a fluid dispenser that includes a reservoir assembly containing the selected fluid, said reservoir includes a resilient body portion having a first end and a second end, a first end sealing cap, and a second end sealing cap assembly to define a reservoir interior, said body having bellows that are defined by a plurality of angular segments each having a pair of sides that are of unequal length with a longer side and a shorter side, said bellows are oriented to retract with said shorter side of each said pair being folded back under said longer side resulting in said body retracting between said first end and said second end with said body maintaining its last selected retracted or extended position, said second end sealing cap assembly includes a penetrable elastomeric member, said fluid dispenser also includes an applicator assembly having a proximal end and a distal end, said proximal end includes a non coring cannula with a lumen having an insertion end that is adapted to insert and penetrate through said elastomeric member and protrude into said reservoir interior enabling fluid communication between said reservoir interior and said lumen, said distal end includes an application element that is in fluid communication with said lumen;
• (b) positioning said application element at the desired location;
• (c) retracting said reservoir body a sufficient amount to initiate the selected fluid to communicate from said reservoir interior to said lumen and onward to said application element;
• (d) applying the selected fluid to the desired location by use of said application element;
• and
• (e) retracting said reservoir body further to a retracted position by a single said angular segment pair causing said shorter side of said pair being folded back under said longer side, with said body maintaining the retracted position thus continuing the selected fluid communication from said reservoir interior to said lumen and onward to said application element.
