2 Claims. (Cl. 141--18) ABSTRACT OF THE DISCLGSURE A rechargeable dispenser having a closed cylindrical dispensing container with an inlet at one end and a nozzle outlet at the other end, the inlet adapted to receive a connection from a Water hose, a ball valve mounted in communication with the inlet and having spring bias means to allow water from the hose to enter the cylindrical container when the container is under suflicient pressure to overcome the spring bias, a release rod extending from the valve and being connected through the nozzle end of the cylindrical container to cause the ball valve to open preliminary to applying Water to the inlet, and a ball check release valve in the nozzle to release the liquid contents of the cylindrical container upon excess build-up of pressure therein, and a stop cock having mounted therein the ball check release valve and operable when the stop cock is in a CLOSED position.
The present invention relates to an improved rechargeable dispenser apparatus, and more particularly relates to an improved rechargeable dispenser apparatus in which certain safety and pressure-release means are provided so that the apparatus is prevented from any explosion or deterioration of the equipment upon subjecting the apparatus to any excessive pressure effects that otherwise would cause the apparatus to exceed capabilities for which the rechargeable dispenser apparatus would otherwise be designed for being used.
An object, therefore, of the present invention is to provide safety and pressure release means for controlling the pressure upon liquids being applied to the rechargeable dispenser apparatus, and also continue the effects of the safety capabilities even while ,the apparatus has been checked out, since often the amount of pressure within a container may be caused to build up upon change of temperature or other residual circumstances.
In accordance with the present invention, the rechargeable dispenser apparatus of the present invention is adapted to mix and dispense a solution with water and solution mixed together.
A further object and feature of the present invention is that an improved structural combination of elements is disposed and provided for dispensing in which the container of the invention may be filled or charged with a liquid or main fluid to be dispensed and is poured into the container upon manually withdrawing or opening a ball check valve, and then water or other mixing liquid may be introduced into the container for mixing therein while the pressure of the applied liquid overcomes the force or bias of the ball check valve until the container is filled and the pressure within the container equals that of the water pressure being applied to the inlet. Thereafter, when any excessive pressure is caused to be generated by foaming or other action within the container, a secondary ball check release valve in the nozzle structure or in a stop cock mechanism disposed within said nozzle line may 'be used to release excessive and dangerous values of pressure which would otherwise cause damage or explosion to the rechargeable dispenser container.
The above and other objects and advantages of the invention will become apparent upon full consideration of the following detailed description and accompanying drawings in which:
FIGURE 1 is a cross-sectional view of the rechargeable dispenser container showing the essential and preferred component structures;
FIGURE 2 is a cross-sectional view taken along lines 2--2 of FIGURE 1;
FIGURE 3 is a cross-sectional view taken along lines 3-3 or" FIGURE 1;
FIGURE 4 is a cross-sectional view taken along lines 4-4 of FIGURE 3; and
FIGURE 5 is a cross-sectional view showing the component parts of the secondary ball check release valve as shown and taken along lines 55 of FIGURE 4.
Referring now to the drawings, there is shown a closed cylindrical dispensing container 10 having a faucet or hose-receiving recess 12 at one end thereof in which there is an inlet 14 adapted to receive a connection from a faucet or water hose shown schematically at 16. The inlet 14 includes a rubber or resilient formed seat 18 which is adapted to secure a firm and fast, non-leak connection for a faucet or hose 16 which may be applied and held thereto. The upper contour 20 of the faucet receiving recess 12 is adapted to come into contact with the peripheral portion of the faucet, as shown, so that when a faucet is applied and inserted into the recess 12, it may beheld firmly by the contour 20 of that portion of the recess 12 so that there is no leakage as the faucet is applied to the rubber or resilient seat 18 of the inlet 14. The inlet 14 is coupled to n communicating orifice or conduit 26 that terminates in a ball valve and seat '28, 30. The ball 30 is connected by a release rod 32 to a handle 34 which is pulled to release the ball 36 from the ball valve seat 28 and a spring biasing means including a spring 40, a spring resting means 42, and a rod limit structure 44, are provided to encompass the operation of the spring biasing means. The support 42 is mounted on the end of a hollow shaft 46 which in itself is mounted from an end of the cylindrical container, as shown. In order to main tain non-leakage characteristics, there is a pair of seals 50, 52 provided for eliminating leakage of the internal fluids or liquids of the container from leaking out along the shaft 32. In FIGURE 2, there is shown the seal 52 along with the shaft rod 32 and the enveloping portion 46a.
In dispensing the mixed fluids that may be applied to the container, it is first noted that the handle 34 is extended for overcoming the spring bias means provided by spring 40 so that the ball 39 is displaced from the valve seat 28, and a liquid or other material sought to be mixed with Water or the like, is applied to the inlet 14. After the initial material is applied through the inlet 14, the handle 34 is released and the ball 30 closes upon the ball valve seat 28. Then a faucet or hose 16 is applied into the recess 1.2 and, in the case of a faucet, the upper portion of the faucet rests against a contour 20 so that there is a small force applied in holding the faucet against the resilient seat 18, and water is thence applied through the faucet and overcomes the pressure of the spring bias means provided by the spring 40 so that the ball 3! is accordingly displaced downwardly. When the container 10 is full, the pressure within the container equalizes with the pressure of the water in the faucet or hose 16 so that the force of the spring biasing means in the spring 40 is caused to close the ball against the ball valve seat 28, and then no more liquid is able to enter into the container It).
In the event excessive pressures develop within the container 10, there is a discharge pipe 60 that extends across the length of the container ltl, as shown, and terminates in a nozzle 62 as shown in FIGURES 1, 3 and 4. The nozzle contains a stop cock 64 that is adapted to turn at least substantially 90 as provided within terms of a limit means 66. The stop cock shown in FIGURES 3 and 4 is in the OPEN position, but the stop cock may be disposed in a CLOSED position upon rotation thereof in a counterclockwise direction, as may be imagined. When the stop cock is thus rotated in the counterclockwise direction with respect to FIGURE 4, then the nozzle and the nozzle pipe 60, 62 are in alignment with a secondary ball check release valve '70 so that, as shown in FIGURE 5, upon excessive pressure being applied from the container 10 through the nozzle pipe 60 and through the communication inlet 72 of the ball check release valve 7t), then the ball 74 of the valve is displaced in a direction that would be downwardly as oriented with respect to FIGURE 5, so that the inlet 72 is opened and excessive pressures are released by the fluid passing through the inlet 72 and exhausting from the chamber 78 through an orifice 80 that would communicate with the nozzle orifice '82 in the nozzle 62.
Thus it is seen that the arrangement of the invention provides a series of safety components and valves which release and prevent excessive pressures and eliminate explosions or over-pressuring of the dispenser container.
Additional embodiments of the invention in this specification will occur to others and therefore it is intended that the scope of the invention be limited only by the appended claims and not by the embodiment described hereinabove.
