Abstract
A hair color delivery system includes a flexible bottle, a dispensing cap having a tapered nozzle, an asymmetric bi-directional valve assembly, and a dispensing tube. The valve assembly comprises a platform, and a pair of valves, comprising tapered extensions through which fluid may be expelled from the bottle and ambient air may enter the bottle. The valves are offset from each other so that they are not co-axial or rotationally symmetric. The delivery system enables a method of substantially continuous delivery of a fluid chemical, yielding a hair treatment that it is easy and safe to use in which the tapered nozzle stays fully charged with product as air can be admitted to a dispensing bottle through a different valve than that used for dispensing.
Claims23
A hair color delivery system, comprising:
- a flexible bottle;
- a cap secured to a mouth of the flexible bottle;
- an asymmetric bi-directional valve assembly situated between the flexible bottle and the cap and secured to the bottle by the cap, the asymmetric bidirectional valve assembly including an input valve defining an input aperture and an exit value defining an output aperture, wherein the exit valve is operable in response to pressure in the flexible bottle;
- and
- a delivery tube having a proximal end coupled to the output aperture of the exit valve and a distal end that extends into the flexible bottle.
An asymmetric bi-directional valve assembly, comprising:
- a platform for covering an opening to a container;
- a first valve comprising a first aperture in the platform and a first tapered extension coupled so as to permit fluid to be expelled from the container in a first direction;
- and
- a second valve comprising a second aperture in the platform and a second tapered extension configured to permit air to enter the container in a second direction, opposite the first direction, wherein the first valve and the second valve are operable in response to a pressure in the container.
A method of substantially continuous delivery of a fluid to a target area, the method comprising:
- providing a flexible bottle;
- at least partially filling the flexible bottle with the fluid;
- expelling fluid from the flexible bottle in response to application of external pressure on the flexible bottle by directing the fluid through a first tapered valve that is operable in response to the external pressure applied to the bottle;
- and
- admitting air into the flexible bottle through a second tapered extension offset from the first tapered extension, so as to adjust internal and external pressures on the flexible bottle, thereby permitting the flexible bottle to at least partially recover from the compression, and maintaining fluid in the tapered valve.
A fluid delivery system, comprising:
- a flexible bottle;
- a cap secured to a mouth of the flexible bottle;
- an asymmetric bi-directional valve assembly situated between the flexible bottle and the cap and secured to the bottle by the cap, the asymmetric bidirectional valve assembly including an input valve defining an input aperture and an exit value defining an output aperture, wherein the asymmetric bi-directional valve assembly is of unitary construction of a flexible material;
- and
- a delivery tube having a proximal end coupled to the output aperture of the exit valve and a distal end that extends into the flexible bottle.
