Abstract
A hose having an observed color, the hose includes a tubular wall having an interior, an exterior and a thickness. The observed hose color changes between a first hose color in a first state and a second hose color in a second state. Differences between the first state and second state may be the result of different expansions of the hose, different pressure pressures within the hose, differences in amount of fluid within the hose and different tensions states for the hose. Observed color changes between the first state and second state may be a color change, a color shade change, alternating rings of at least two different colors or shades of color along the length of the hose, a color pattern change or even the generation of indicia on the hose.
Claims25
A hose having an observed hose color and length, comprising:
- a tubular wall having an interior and an exterior;
- wherein said tubular wall is a segmented tubular wall;
- and wherein the observed hose color from the exterior changes between an observed hose first color in a first state and an observed hose second color in a second state.
A hose having an observed hose color and length, comprising:
- a tubular wall having an interior and an exterior;
- wherein said tubular wall has an effective tubular wall thickness;
- wherein said effective tubular wall thickness is reduced when changing from a first state to a second state;
- and wherein the observed hose color from the exterior changes between an observed hose first color in said first state and an observed hose second color in said second state.
A hose having an observed hose color and length, comprising:
- a tubular wall having an interior, an exterior and an interior surface;
- wherein said interior surface includes a thin color layer;
- and wherein the observed hose color from the exterior changes between an observed hose first color in a first state and an observed hose second color in a second state.
A hose having an observed hose color and length, comprising:
- a tubular wall having an interior and an exterior;
- wherein the observed hose color from the exterior changes between an observed hose first color in a first state and an observed hose second color in a second state;
- and wherein said observed hose second color in said second state is alternating rings of at least two different colors along the length of the hose.
