Description of the preferred embodiment Referring now by reference characters to the drawings which illustrate preferred embodiments of the present invention, A generally designates a liquid dispenser of cylindrical or fnusto-conical form, which may be fabricated of molded plastic, desirably transparent, such as Lucite, having a side wall 1 and being open at its upper end as at 2. Opening 2 is eccentrically located by reason of one portion 3 of side wall 1 being of relatively greater thick- 3,425,603 Patented Feb. 4, 1969 ness than the opposite portion 3' thereof. Spaced downwardly from its upper open end 2, side wall 1 is continuous with an inward, rounded, bottom-forming extension 4, located upwardly of the lower end edge of side wall 1 and cooperating with the adjacent portions of said side wall 1 thereabove to define a receptacle or bowl 5 for receiving liquid through the upper open end 2. Centrally of extension 4 there is formed a discharge orifice 6 which, at its lower end, opens into a chamber 7 defined by the horizontally presented under face 4' of extension 4 and the adjacent portions of side wall 1 therebelow. Side wall 1 downwardly of the under face 4 is relatively reduced in thickness to present an annular shoulder 8 against which abuts the upper edge portion of a closure 9 fitted snugly within the lower end of dispenser A and serving to divide chamber 7 into upper and lower sections 10, 11, respectively. Formedyin the body of closure 9 is a flow-directing passage 12 of general funnel shape having a relatively wide upper mouth 13 and a lower diametrically reduced outlet 14 with the intervening wall portion tapering inwardly and downwardly. Outlet 14 is vertically aligned with orifice 6.
Presented within upper chamber section 10 is a valve 15 disposed on its upper surface across the lower end of orifice 6 with the confronting portions of under face 4' providing a valve seat, as indicated at 16, with said valve 15 carrying a peripheral sealing member 17, such as an O-ring, for development of a liquid-proof joint with such sea-t. Valve 15 incorporates a short depending stem 18 having a transverse opening 19 for extension therethrough of a spring 20 produced from a length of suitable rod stock. One end portion of spring 20 is formed for biasing into a loop 21 which is disposed within upper chamber section 10 having its upper margin bearing against the under face 4. The free end extremity of spring 20 adjacent loop 21 is embedded in closure 9, as at 22. The opposite end portion of spring 20 is secured, as by welding or the like, as at 23, to the lower end of an actuator rod 24 which projects slideably upwardly within a passageway 25 provided within wall portion 3 and communicating at its upper end with the lower end of an enlarged socket 26; said latter opening at its upper end through the upper surface of wall portion 3. Within said socket 26 rod 24 is fixed to the lower end of the shank 27 of an actuator head 28; said shank being slideable within socket 26. The upper extremity of actuator head 28 is diametrally enlarged, as at 29, to provide a convenient pressure-receiving surface located normally upwardly of the upper surface of wall portion 3 by reason of the bias of spring 20. For limiting the travel of actuator head 28 within socket 26 there is provided a detent pin 30 located within socket 26 for abutment against the upper and lower shoulders 31, 32, respectively, of a lateral recess 33 formed in shank 27.
Through bias of loop 21 spring 20 is prejudiced upwardly at its rod-attached and thereby normally urging valve 15 into closed position and rod 24 upwardly within passage 25 so that the upper enlarged end of actuator head 28 will be presented above wall portion 3 (FIGURE 3). By downward pressing of actuator head 28, as through applying the users thumb against the diamet-rally enlarged portion 29, actuator head 28, together with rod 24, will be caused to slide downwardly forcing the attached end of spring 20 downwardly against the inherent bias thereof so that loop 21 will be momentarily enlarged with attendant downward, opening movement of valve 15 so as to bring discharge orifice 6 into communication with outlet 14.
Accordingly, in usage, with valve 15 in closed condition, the user will fill bowl of dispenser A with any preselected liquid and with the knowledge as to the amount thereof because of the specific volume of said bowl 5. Dispenser A may then be placed in superimposed relationship to a container designed to receive the liquid within bowl 5 for ultimate mixing or other purposes. By manipulation, as above described, of actuator head 28, the contents of dispenser A may be caused to flow to the underlying container by travel through now-opened orifice 6, passage 12 and outlet 14; the user maintaining actuator head in downwardly pressed position until the dispenser contents are exhausted. Thereupon, by release of the pressure upon actuator head 28, valve 15 will be automatically returned to closed condition through bias of spring 20. It will thus be seen that the dispenser contents may be readily discharged by simple operation and With the dispenser at all times being in vertical position, thus obviating the heretofore need for inverting or tilting measuring dispensers for release of the contents.
Referring now to FIGURES 4, 5 and 6, B generally designates a liquid dispenser fabricated, if desired, of molded plastic and comprising a side wall 41 which may be, optionally, of general cylindrical form or of down wardly tapered contour. At its upper end, dispenser B is open, as at 42, to form the enlarged mouth of a receptacle or bowl 4-3, the bottom wall 44 of which is defined by a rounded generally transverse portion continuous with the inner face of side wall 41 and presented spacedly upwardly from the lower end thereof. Provided eccentrically Within bottom Wall 44 is the upper end of an outlet passage 45 progressing downwardly along a path parallel to the vertical axis of dispenser B. The lower end of passage 45 is terminated by an inclined surface 46 for directing liquid through an orifice 47 provided in the inner side portion of the wall of passage 45; the axis of orifice 47 being normal to that of passage 45. Orifice '47 opens into the inner end of a recess 48 and at its outer end opens through side wall 41, as at 49. Immediately proximate orifice 47, recess 48 communicates with a downwardly extending passage 54), through the upper end thereof; the lower end of said passage 50 constituting a discharge port 51.
Provided for close fitting disposition within the outer portion of recess 48 is an annular closure plug 52 having on its inner surface an annular recess 53 and a central socket 54. Slideably received within said socket 54 is the reduced end 55 of a valve stem 56 which is presented transversely of dispenser B extending through recess 48, across passage 45 and through an opening generally indicated 57 formed in the opposed portion of side wall 41; said stem 56 being of such length so as to have an end portion 58 extending laterally outwardly of the proximate portion of side wall 41. Integral with valve stem 56 is a diametrally enlarged valve head 59 being located immediately inwardly of orifice 47 and of greater relative transverse extent so as to serve to occlude same. Thus, the proximate wall portion of orifice 47 serves as a valve seat for valve head 59 which latter may be provided with a peripheral sealing member 6% for assuring of a positive reliable liquid-proof joint. Urging valve head 59 into orifice-closed condition is a compression spring 61 which at one end bears against the face of head 59 opposite that confronting orifice 47, while the other end of said spring 61 is received within annular recess 53 of plug 52. In order to prevent any unauthorized escape of liquid through opening 57 by leakage about valve stem 56, the said opening may communicate with an enlarge continuous recess 62 within the inner end of which may be presented a seal 63 with a molded insert '64 disposed thereagainst.
Through bias of spring 61 valve head 59 is maintained in normally closed condition whereby the user may fill bowl 43 and passage with the preselected liquid. Dispenser B as so supplied may then be located in superimposed relationship to a container designed to receive the dispenser contents. Thereupon the operator need but apply inwardly directed pressure against the exposed end 58 of valve steam 46 so as to direct same toward side wall 41 thereby causing valve head 59 to be moved away from its seat while placing spring 61 under tension. With orifice 47 thus opened, liquid will flow from passage 45 through said orifice 47 and thence through passage and outwardly of discharge port 51 for reception within the container. After liquid discharge, the user need merely remove pressure from valve stem 5d whereupon under influence of spring 61 valve head 59 wlll be effectively and reliably returned to orifice closed condition.
It should be understood that changes and modifications in the formation, construction, arrangement and combination of the several parts of the valve operated liquid dispenser may be made and substituted for these herein shown and described without departing from the nature and principle of my invention.
