Method and system for transfer of fluid and dry materials from an inverted holding container to a paired docking station receptacle
First Claim
1. A gravity-assisted dispensing system for hands-free and spill-free transfer of liquid and dry materials from a holding container into receiving vessel, said system comprising:
- i.) a dispensing assembly comprising;
a.) a bottle cap member configured for threaded connection to the neck opening of the type of holding container with which said dispensing system will typically be used for material transfer, and having a bottom surface, a central spring housing upwardly depending from said bottom surface, said spring housing having a top central opening, a plurality of spaced-apart material transfer holes through said bottom surface;
b.) valve closure means adapted for close association with said spring housing to block material flow through said material transfer holes, and having an activation pin centrally extending through said top central opening and said spring housing when in a closed position;
c.) spring means within said spring housing and adapted for biasing said valve closure means into said closed position;
d.) spring retaining means associated with said spring housing adapted for maintaining said spring means within said spring housing; and
ii.) a receptacle comprising;
(a) a housing having a top end opening sufficiently wide for receipt of said entire bottle cap member, an inside surface, and a bottom discharge opening;
(b) at least one protrusion on said inside surface of said receptacle at a height allowing each said protrusion to enter said side channel of said bottle cap member once said dispensing assembly is fully positioned within said receptacle housing;
(c) a flange radially extending from said top end opening of said receptacle housing; and
(d) a spring nut engagement member secured within said discharge opening, said spring nut engagement member and having tapering upper surfaces configured for partial insertion through said cutout pattern in said spring nut and a top end;
whereby spill-free material transfer is achieved when said dispensing assembly is secured around the neck opening of a holding container, and the holding container is inverted, and said discharge opening of said receptacle is in communication with a receiving vessel, since material within the holding container is not transferred into said receptacle until said bottle cap member is fully within said receptacle housing against said inside surface so that said top end of said spring nut engagement member contacts said activation pin a sufficient amount to unseat said valve closure means fractionally from said spring housing and reveal said spaced-apart material transfer holes adjacent to said spring housing, and whereby material flow ceases as soon as said bottle cap member starts to be withdrawn longitudinally from said receptacle housing and said activation pin breaks contact with said top of said spring nut engagement member and allows reseating of said valve closure means against said spring housing well before said bottle cap member leaves said receptacle.

Abstract
A dispensing system and method for locked spill-free transfer of liquid and dry materials. The dispensing assembly attached to the material holding container has a bottle cap with a slotted spring housing, small notch, spring-biased valve closure member with activation pin, and spring nut with cutout. The paired docking station receptacle includes a housing having an upper flange, bottom discharge opening, interior protrusion, and upwardly tapering spring nut engagement member with spaced-apart radially-extending flukes positioned within the discharge opening, the upper surface of which are configured for partial insertion through the spring nut cutout. Thus, when the protrusion is aligned with the notch and a bayonet turn is applied to the bottle cap, the spring nut engagement member unseats the valve closure member and allows material transfer. The dispensing system herein can be used by manufacturers of equipment requiring periodic renewal of dry and liquid materials to limit their source.
