Abstract
A disposable article, e.g., useful as a sanitary protection device. The disposable article has a primary structure and a liquid-sensitive signaling element in liquid communication with the primary structure. Upon exposure to fluid, the liquid-sensitive signaling element expands to signal the user that the article is approaching capacity.
Claims16
A disposable article comprising:
- a) a substantially planar primary structure having an outer perimeter and suitable for placement adjacent a mammalian body surface;
- and
- b) an expandable, liquid-sensitive signaling element arranged and configured adjacent at least a portion of said outer perimeter, the signaling element comprising resilient material held in a strained configuration that is capable of expanding to a relatively unstrained configuration upon exposure of the signaling element to bodily fluids.
A method of making a disposable article comprising the steps of:
- a) forming a primary structure;
- b) manipulating resilient material into a deformed condition;
- c) restraining the resilient material in the deformed condition to form a signaling element;
- and
- d) attaching the signaling element to the primary structure.
