Abstract
A sanitary liquid dispenser having an essentially spherical housing with a downwardly extending portion surrounding a recessed discharge port, the dispenser further including a proximity detector for activating a discharge mechanism when detecting the proximity of an object therebeneath, the dispenser further including therewithin a fluid reservoir having a disposable deformable bag with an essentially vertically disposed and integrally formed extension projecting downwardly therefrom and wherein there is included a valve disposed within such downwardly projecting extension or within a contiguous supporting member.
Claims31
A sanitary liquid dispenser comprising:
- a. an essentially spherical housing having a lower hemisphere and a detachable upper hemisphere;
- said lower hemisphere including at a lower surface thereof, a downwardly extending portion surrounding a vertically disposed aperture leading into the interior of said housing;
- b. mounting means connected to the exterior of said housing for mounting said dispenser on a support;
- c. proximity detection means including a proximity detector mounted in the lower part of said lower hemisphere for detecting the proximity of an object therebeneath when near said proximity detector and for producing an electrical signal indicative of the detection of said object;
- d. electrical valve-actuating means connected to said proximity detection means and responsive to said electrical signal for assuming a valve actuating condition;
- e. fluid reservoir means including a disposable deformable bag, said bag having an essentially vertically-disposed and non-deformable, integrally formed extension projecting downwardly from said bag and including a valve seat and a valve gate within said extension;
- and
- f. means including said valve-actuating means when in said valve actuating condition for opening said valve for a predetermined time interval thereby to permit a predetermined quantity of fluid to flow from said bag.
A sanitary liquid dispenser comprising:
- a. an essentially spherical housing having an lower hemisphere and a detachable upper hemisphere;
- said lower hemisphere including at a lower surface thereof, a downwardly extending portion surrounding a vertically disposed aperture leading into the interior of said housing;
- b. mounting means connected to the interior of said housing for mounting said dispenser on a support;
- c. proximity detection means including a proximity detector mounted in the lower part of said lower hemisphere for detecting the proximity of an object therebeneath when near said proximity detector and for producing an electrical signal indicative of the detection of said object;
- d. electrical valve-actuating means connected to said proximity detection means and responsive to said electrical signal for assuming a valve-actuating condition;
- e. fluid reservoir means including a disposable deformable bag, said bag having an essentially non-deformable vertically disposed, and integrally formed extension projecting downwardly from said bag;
- f. curved rigid support means within said housing, said support means being shaped for conforming contiguous fit to the exterior curvature of the lower exterior surface of said deformable bag;
- g. downwardly extending rigid tubular guide means integral with said support means, said guide means receiving and enclosing said vertically disposed extension, said guide means further having an electrically actuable valve mounted therein;
- and
- h. means including said valve-actuating means when in said valve-actuating condition for opening said valve for a predetermined time interval thereby to permit a predetermined quantity of fluid to flow from said bag.
A container adapted for inclusion within a dispenser, said container comprising a fluid containing bag having upper and lower portions, said bag having a major part thereof of reversibly deformable material adapted to deform inwardly as fluid is drained from said container thereby preventing entry of air thereinto to replace drained fluid, an essentially non-deformable tubular extension integrally joined to said fluid container adapted to conduct fluid outwardly from said container, said tubular extension having mounted therein a magnetically actuable single-seated valve member selectively conditionable between open and closed conditions, thereby to permit or prevent flow of fluid from said container.
