Application March 10, 1955, Serial N 493,529
8 Claims. (Cl. Z22- 479)V The present invention relates generally to the field of liquid dispensers, and more particularly to a liquid dispenser that is self-ventingand seals automatically. VThis application is an improvement over my co-pending application Serial No. 384,376 filed in the United States Patent Oliice October 6, 1953, now Patent No. 2,779,517, issued January 29, 1957.
The major object in devising the present invention is to provide a liquid dispenser that can be removably ai'hxed to such containers as drums, carboys, tanks and lil-:e commercial vessels, by means of which liquid may be discharged therefrom at a controlled rate, which dispenser is self-vented due'to the fact that a constant atmospheric pressure is maintained thereby within the container on which it is mounted.
Another object of the invention is to supply a dispenser that automatically assumes and maintains a liquid seal for the container with which it 'is associated until application of a duid discharge force is applied thereto.
A further object of the invention is to furnish a dis penser that allows for discharge of the fluid contents of an industrial container as required, with the contents of the container being subjected to a minimum of atmos pheric contact. Y
A still further object of the invention is to provide a dispenser that may be opened and closed without the use of tools, that is easy to mount on or remove from a container, and which eliminates the possibility of inadvertent or accidental fluid discharge from the container.
Yet another object of the invention is to provide a dispenser that permits liquid to be freely poured from a container within a minimum Yof time without unde sirable wasteful splashing and gurgling thereof, which dispenser prevents any appreciable escape of volatile vapors from the fluid contents of the container on which it is mounted.
Another object of the invention is to furnish a dispenser that is ideally suited for use on containers in which inammable liquids or fluids having dangerous physical characteristics are stored, due to the spring means associated with the dispenser which at all .times urges and maintains same in closed position whereby it cannot inadvertently assume an open position without application of actuating force that must be constantly maintained thereon to eiect a continuing flow of fluid rom the container.
A further object of the inventionis to supply a dispenser that eliminatesV the necessity of opening a vent in a container on which it is mounted in order to discharge uid therefrom.
These and other objects and advantages of the-present invention will become apparent from the following description of a preferred and alternate form thereof, taken in coniunction with the accompanying drawings illustrating those forms, in which:

Figure 7 is a vertical cross-sectional view of a second alternate form of the invention;
Figure 8 is a vertical cross-sectional View of a third alternate form of the device; and
Figure 9 is a vertical cross-sectional view of a fourth alternate form of the invention.
Referring now to the drawing for the general arrangement of the invention, it will be seen that a fluid container C is provided in which a tapped bore R is formed that is removably engaged by a threaded portion P of the dispenser D. Container C may be of any desired size or shape as long as it is adapted to be so positioned that liquid may drain therefrom through the bore R.
A uid discharge opening A is formed in threaded portion P, which opening is defined by a body shoulder B and communicates with a tubular pouring spout S. Spout S slidably supports within its contines a springloaded sleeve T which embodies a normally sealed air vent V as well as a liquid sealing member M that removably contacts Vshoulder' B. An actuating handle H is rigidly aixed to sleeve T, and upon application of manual force thereon above a predetermined value, the sleeve moves inwardly relative to spout S whereby the Vent V is then in communication with the atmosphere and the member M displaced from shoulder B. When handle H is moved downwardly to position Y shown in phantom line in Figure 2, and then slightly rotated, the sleeve T can be removably locked in a predetermined longitu-dinal position relative to the spout S whereby liquid may be discharged through spout S without gurgling, for in order to equalize the pressure in the container relative to atmospheric pressure during liuid discharge from the container, it ows inwardly through vent V Without coming into contact with an oppositely moving liquid from spout Si.
ln detail, portion P and spout S are preferably fabricated as an integral unit, and portion P includes a cylindrical plug l@ in which threads 12 are formed on the exterior surface thereof. A ring 14 extends outwardly from plug lil and is disposed above threads l2. Ring 14 has a flat under surface 16 which grips a washer 18 disposed on the upper surface of top 2i) of the container to effect a duid-tight seal therewith when the plug is screwed in bore R. As may be seen in Figure 2, ring 14. also has a circular flange 22 extending upwardly therefrom. A number of circumferentially spaced lugs 2e are rigidly aixed to ange 22 and project outwardly therefrom. Lugs 24 can be grasped manually or by means of a suitable turning tool (not shown) to screw the plug 1t) into or out of position in bore R.
Pouring spout S is formed from a rigid tubular member which extends upwardly from plug lil, and a bore 23 is provided in tubular member 25 that extends downwardly through ring 14 into plug it? to define a circular body shoulder 3@ with a counterbcre 32 of slightly larger diameter than bore 2S. Three vertically disposed slots 34 extend downwardly in tubular member 25 from the upper circumferential end thereof, each of which slots terminates in a relatively short horizontal extension Se that terminates in a slightly enlarged portion 36a. The three slots 34 which are identical in shape, are preferably spaced from one another by Sleeve T includes a rigid tube 3S of such external Vent- V and be so situated relative to plugV lliand pouring spout S,
`asume Y Y diameter as to snugly and slidably engage the interior surrateY of flow of liquid from the inside of container C face of tubular member 26. Tube 38 has the handlesH4 rigidly mounted thereon. rigid arms 40 which are horizontally disposed and rigidly aflxedrto the upper exterior surface of tube 38., Three of the'arms 4) are so disposed as to extend'outgfvardlyV through slots 34and be vertically' movable therein;` The four arms 40 are preferably formed,withenlargedyertically disposed end portions 49a, which' armsj(Figure 2) rigidly support a horizontally positioned ring 42,which slidably engages the exteriorsurfaceoftube 38.
A` helical spring 44, preferably fabricated from flat In detail, handles H are four resilient stock, is provided that is suiiciently long to at Y all times be in compression when disposed in an encircling position about pouringrspout S; When so situated the upper end portion 44arof spring 44 abuts against the under side of ring 42, and the lower end portion 44b thereof disposed on theupper annulus shaped surface 42a of Yplug 10 that is situated between tubular member 26 and ange 22.7
The Vlower end portion of tube 38 has Vthreads 50 formed thereon that Vengage a tapped recess 5,2 that extends downwardly from the upper surface 54. of an' annular sealing member 56. A washer 58 formed of a resilientsheet material thatV is` impervious to the solvent action Vand the chemical characteristics of the liquids that will'beheld in container. C is bonded to the surface 54 of the sealing member.
A vertically extendingT wall 60 occupies an intermediateposition .within the confines of tube 38, and extends the length thereof.V Wall 60 subdivides the interior of tube 38 -into two longitudinally extending passages, the Vfirst of the passages being vent V, and the second passage 61 beingof somewhat larger transverse cross section than vent V to permit an appreciable amount of liquid in container C.to flow therethrough. l
,The upper end of tube 38 has an end piece 62 extend-V ing thereacross. The end'piece has an air inlet port 64 formed thereinY that is in communicationwith VentY V, and au tapped Yliquid'discharge port 66' through which liquid can ilow from the ysecond passage 61. Tube 38 Yhas an elongate opening 68 formed in the lower side,k portionthereofopposite vent V, and the opening being in communication with Ythe fluid passage 61. A transversely disposed bore 70 is formed inthe lower portion of tube 38, Ywitl'i the boreV establishing communication between vent V and countei'bore 32 in Yplug 16.
The useY and operation of the preferred form of the invention is extremely simple; YWhen the dispenser is Vmounted on. a container C as previously explained ,in
detail, the spring 44 at all times tends to expand to move the ring 42, sleeve T, and sealing member M upwardly.
Upward movement ofrthefassembly is limited by the .Y
resilient sealing washer 58 being brought into pressure sure contact of washer 58 not only prevents liquid ilow- Y ing from the inside of container C to pouring spout S,
but prevents entry of air `from the atmosphere through bore 70 to contact the liquid held in the con-,- tainer'. Y
AIt will be apparent that upon a downward force of the required magnitude being exerted on handle H, the Y sleeve T, vent V, sealing member M and sealing washer VBy moving the handle H downwardlyY until the arms 40 are disposed at the position Y shown in phantomy line Y in Figure 2, and then slightly rotatingthe handles, `the armsV can be causedV to be disposed in enlarged slot exten; sions 86a. The arms 40 when so disposedY causethe sleeve T, vent V, member M and sealing washer 58 to Y 58 are moved downwardly relative to pouring spout S. Y
, 4 n as shown in phantom line in Figure 2 that the maximum can take place from the invention.
A rst alternate form of the dispenserris shown inYV Figure 5. A cylindrical shell is provided thathas a plate 82 normally disposed to the interior surface thereof and intermediatelyV situated between the ends Yof the shell. Plate 82 rigidly supports a first tubular member 84 that extends downwardlythrough'an opening 85 formed in a wall 88 that denes'thercontainer C in which the liquid is disposed. Tubular member 84 is formed with an upwardly and inwardlyY extending tapered circumferential edge portion 86. An annular liquid sealing member 88 is supplied that has an upwardly and inwardly tapered circumferential edge 88a that is adapted to set against edge portion 86 and effect a liquid seal therewith. Y
Liquid sealing member 88 closes the lowerV end of a second tubular member 90 that is slidably'mounted in 'the frst'tubular member 84. Second tubular member Y90 as may be seen in Figure 5 is formed .with a curved up-V wardly vdisposedv'portion V92A from which liquid can be discharged.. A'longitudinally extending intermediately disposed wall 94 divides` the interior of thesecond tubularV member 9,0 into an air vent 96 and a liquid discharge pas# sage 98. Air is admittedinto vent 96 through an inlet port 100 formed in the curved portion 92 and discharged from the lower part of the vent through a discharge port 102 formed in rst tubular member 84.
. An inverted cap shaped housing 104 that includes YaV downwardly extending side wall 106 is provided, and is axed to the exterior surface Yof second tubular member 90 in such a manner Vthat the sidewall 106 oyerlapsthe upper portion of shell 80, and a helical spring 107 jthat downwardly therewith, andV liquid sealing edge 88a separated from tapered'edge 86, liquid in container C' can now ow into liquid passage V98 through an opening'109 formedrin the lower portion of second tubular member 9,0. Atmospheric airows inwardly into container C through vent 96 and port 102 as liquid is discharged Vfrom the container, to equalize the pressures betweenV the interior and exterior of the container, and thus prevent gurgling of the liquid as itis discharged lfrom spout 92.
Of course, upon the actuating force `being removed from housing 104, the spring 107 expands, and the Vedges 86 and 88a are brought together into liquid sealing contact. In this manner, communication between liquid passage 98, Yair vent 107, fand the interior of container C' is blocked until the housing 104 is again moved to an actuating position.
A second alternate form of the invention is shown in Figure 6 in which it will be seen that a tubular liquid dischargeV memberV is provided. An intermediately positioned valve body 122 thatrotatably supports a plug 124 divides member 120 into an outwardly disposed` porf tion 120a and an inwardly situated portion120bY Portion 120a is formed Vwith a downwardly extending `outer end 120C.' Portion 120b is provided withthreads120d on the free end thereof.
A tubular air vent defining member 126 is positioned above liquid discharge member 120 and follows Vthe general contour thereof. Vent-memberj 126 isY alsodivided; by valve body 122'into an outwardly. disposed portion 126a and an inwardly disposedV portion 126b, which Vlatter Vhas threads'r120dformed therein: In*V addition it will be noted that portion 1261)v extends inwardly beyond the termination of portion b`to prevent air passing inwardly through the vent from mixing with liquid flow-V ing outwardly through the liquid discharge member.
Plug 124 has two parallel, vertically spaced, transverse bores and 132 formed therein that can be concurrently brought into alignment with the interior of portions 120H, 120b and portions 126a, 126b, respectively. Plug 124 may be rotated by means of a handle 134 rigidly athxed to the upper portion of the plug. inadvertent displacement of plug 124 from the valve body is prevented by the use of a downwardly extending threaded rod 136 that projects through a bore in a plate 138 that covers the lower portion of valve body 122. A nut 140 engages rod 136 and abuts against the exterior surface of plate 138.
The second alternateV form of the invention provides a valve in which an air vent passage is formed and terminated concurrently with the opening and closing of the valve by use of handle 134. This alternate form operates in the same manner as the preferred form, except that the control valve therefor is positioned on the exterior of the liquid container with which it is used.
A third alternate form of the invention is shown in Figure 7 which diifers from the second alternate form only in that a continuous tubular liquid discharge member 120. and tubular air vent dening member 126 is employed therein. The outer ends of members 120', 126' are slightly curved, and are concurrently opened and closed by pivotal movement of a convex-concave valve member 142. Valve member 142 is provided with two laterally separated legs 144, the inner end portions of which are pivotally supported by screws 146 rigidly aixed to liquid discharge member 120. A handle 148 is mounted on valve member 142 that is utilized in moving the valve member to an open or closed position.
The fourth alternate form of the invention is illustrated in Figure 8, and is particularly well adapted for use with a relatively large liquid container, such as a ve gallon can or fifty gallon drum (not shown). The top of a container is shown in this ligure which is provided with a liquid outlet generally designated by the numeral 162. Outlet 162 includes a short, cylindrical shell 164 that projects outwardly from the circumferential edge portion of top 160 and defines a liquid outlet opening 166. Shell 164 terminates at its outermost end in an annular bead 168, which shell is adapted to receive and hold a resilient ring 167 within the contines thereof. A longitudinally extending first recess 170 is formed on the interior surface of ring 167 that is preferably of rectangular transverse cross section, or at least has a flat circumferentially extending interior surface 167a.
Two oppositely disposed, longitudinally extending recesses 172 are formed on the interior surface 167a of ring 167 and preferably located 90 from the rst recess 170. A combinedV pouring spout and air vent 174 is provided which is slidably mounted within the confines of ring 167. This combination spout and vent 174 is preferably fabricated as an integral unit from one of the numerous commercially available synthetic plastic materials suitable for this purpose, the selection of which is determined by the fact that it will not be physically or chemically aected by the fluids to be dispensed therethrough. It will also be seenin Figure 8 that the combined spout and vent includes an elongate tubular member 176 inV which a longitudinally extending transverse wall 178 is formed that defines an air vent 180. The surface 178:1 of wall 178 and the interior surface 176a of the tubular member define a bore 182 through which liquid is discharged. Vent has a portion 183 that extends beyond the end 184 of tubular member 176 and is disposed within the container for the same reasons previously outlined in connection of those forms of the invention shown in Figures 6 and 7.
As illustrated in Figure 8, tubular member 176 has a longitudinally extending rib 177 formed on the exterior surface thereof, which rib leads to a transversely disposedy sealing ring 188 also formed on the exterior of the tubular member. Rib 177 is slidably mountedin recess 170 and permits longitudinal movement only of the combination spout and air vent 174 in shell 164.
Two oppositely disposed arms 179 are pivotally supported on the exterior surface of tubular member 176l by pins 17911, which arms are of such transverse cross section as to permit slidable movement thereof when inserted within the contines of recesses 172. Arms 179 project beyond the end of shell 164 and are connected to opposite circumferential edge portions of an annular cap 185. Cap 185 (Figure 8) includes an annular plate 184 from the circumferential edge of which a continuous circular side wall 187 depends to terminate on the outer end thereof in a liange 18S. At least a portion of frange 188 extends inwardly and is adapted to removably engage the inner face 199 of bead 168. Cap 185 as well as arms 179 are fabricated from a plastic material which has Asorne rigidity, but is still sufficiently resilient to permit placement of the cap in that position shown in phantom line.
When arms 179 are in alignment with and in the same plane as that of the longitudinal axis of shell 164, the
' tubular member 1'74 can be moved inwardly suiciently to permit the cap 185 to removably engage the shell as shown. When member 174 is in the solid line posi-tion of Figure 8, cap 18S removably effects a liquid and vapor-tight seal with shell 164. Liquid cannot escape through the recesses 172 during pouring thereof, nor can air enter the confines of the container, for as liquid is poured from the container, ring 188 abuts against the inner surface of top 160 completely obstructing communication between the container interior and the outer atmosphere.
When cap 185 is in a liquid sealing position on bead 168, it seals the outwardly disposed positions of recesses 172 and prevents passage of liquid or outside air therethrough. From the above description it will be seen that the ring 188 serves a dual purpose; that ofV sealing the inwardly disposed ends of recesses 172 as liquid is poured or discharged from the container, and that of serving as a stop to limit the maximum outward movement of tu- 'bular member 174 relative to, shell 164. Cap 185 also serves a dual purpose in that it seals the combination air vent and pouring spout 174 and prevents inadvertent movement thereof relative to liquid outlet 152. The operation of the fourth alternate form of the invention is the same as that of the preferred form when it is in a liquid dispensing position.
A possible variation in the fourth alternative form of the invention is to position a helical spring that is at all times under compression in an encircling position around the combined spout and air vent 174. The lower end of the spring rests on the upper surface of the resilient ring in which the spout and vent 174 is slidably mounted. The upper end of the spring is affixed to the exterior surface of the spout-and-vent combination, which spring at ali times urges it outwardly toward a pouring position in substantially the same manner in which the preferred form of the invention functions. It will, of course, be realized that this spring-loading of the combination spout and vent oniy results in outward movement thereof when the resilient cap is not in locked position on bead 156 of outlet 16?..
The fifth alternate form of the invention shown in Figure 9 is particularly adapted for use in discharging liquid from drums or other containers (not shown) that `include a wall 199 in which a tapped bore 1%2 is provided through which fluid is discharged. Another tapped bore (not shown) is normally provided for such containers and is usually positioned in that side portion of wall 193 opposite to the discharge bore 192. This secf ond tapped bore serves as an air vent during the time iiuid is being discharged through bore 192. When liquid V194 for reasons that will be explained hereinafter.
Y Y '7 is shippedor storedin a container of this type, both tapped bores are closed by threaded plugs (not shown) that can be easily removed therefrom by means of a socketwrehch or the like.-Y Y Y Inusing the fifth alternate form of the invention, butV Y one plug isA removed from one of the tapped boresV 192. VThis form includes a cylindrical body 194 having threads 196 formed on the exterior surface thereof that can 'be caused to removably engage the ytapped bore 192 to establish communication with the liquid in the container. A cylindrical support 195 projects outwardly from bodyV The support is formed with a circumferentially extending groove 19511 on the interior surfacey thereof. A bore I198 extends through body 194 and support 195, in which bore a combination liquid discharge spout and air vent generally denoted by the numeral 200 is slida'bly mounted. The combined spout and vent embodiesv a tubular member 202, a straight portion 202a of which 'is slidably mounted in bore V198, and a downwardly andrforward'ly curved portion 202b of which at all times Vprojects out- Y side the confines of bore Y19S. VA resilient ring 199 situated in groove 195a that slidably engages the exterior surface of portion 202:1 eiects a duid-'tight seal therewith.
A longitudinally and transversely disposed wall 204 is provided inside the combined spout and` vent that divides the interior thereof into a liquid dispensing passage 206 and air vent passage 208. A cap 210 of any desired construction closes the'inwardly disposed end of member 202.V andextends outwardly beyond the exterior surface thereof. When the cap 210 is positioned againstthe inwardly disposed edge Vof body 19.4, it serves as a stop to limit the maximum forward movement of the combination spout and vent memberV 200.
It will be seen in Figure 9 that a transverse port 212 Y Y Vis formed in the inwardly disposed portion of' member portion 202:1, which portrcommunicates with passage 205. However, when the combined spout and vent 200 is in its forwardm'ost position as shown in solid line, port 212 is sealed Yout ofcommunication with vthe container interior as it resides Within the confines of body 194. A relatively large opening 214, preferably Yof substantially the same area vas that of the vent passage 208, is formed in member portion 202a. VThis opening 214 is sealed from communication with the interior ofthe container asY it -is situated within 'body 194 when the device is in the posi- -tion shown insolid line.V l The threaded body 194 has two oppositely disposed legs 194a projecting forwardly therefrom that support pins 21'6 or other suitable means on which pairs of linksV 220 are pivotally mounted. A rigid ring 222 is aixed or transversely formed on the combined vent and spout portion 202a, forwardly from legs 194g, Pairs of links 224 are pivotally mounted on pins 226 projecting oujtwardly from ring 222. The free ends of links 220V and 224 .are pivotally joined by pins 22S, as may be' seen in Figure 9. The upwardly and outwardly extending linkV in each pair of links 224 continues 'by means of an eX- tension 224e to a position above the combination vent -and spout where -the extensions 224a'areV brought together to form a common forwardly extending handle A helical spring 232 is provided that is at all times in Ycompression and encircles the combined vent Vand spout portion 20211. The inwardlyV disposed end of spring 232 abuts against the forward faceY of body 194, and the forward endof the spring bears against the rear face ofV ring 222. ltrwill be apparent that with this construction the bore 212 and opening'214 are at all times maintained out of communication with the container interior except when the handle 230'isV moved in a counter clockwise direction as shown. Y UponV such m'ove- Y ment of the handle, the combined spout and vent 200 is moved `inwardly into the contines of the container sufciently to bring. bore 212 and opening `214 into corn.
In order to attach a hose to the outer extremity of the combined spout and vent 200, or to provide a resilient liquid conduit 4by'means Aoffwhich liquid may be trans-Y ferred into a particular container, a tubular ,liquid` discharge member 240 is provided. Member'V 240:.has a rear portion 242 in which a transverse circular rib ,243 is formed on the interior thereof. Portion v242 swagcs down to a forward part 244 considerably smaller in in- ,terial` diameter.
an air vent; passage 208 and a fluid carrying passaget206,
Vent passages 208 and 208', and passages 206 and 206' communicate with one another when member 240 is dis- Y posed on the combined spout and vent member 200.'
( Member 240 is preferably` held on the.V outer end of the combination spout and vent by the use of a transverse, circumferentially extending groove 248 formedV in'the member near the end thereof. Due to the resilient'fnature of the material from V which it is fabricated, member 240 canthen be slipped on the, end portion of the combined spout and vent where it is removably held in position thereon by rib 243 positioned ingroove .248. Threads 250 formed' on the exterior of part`244 permita hose (not shown) tobefremovably connectedtheretor.
While the dispensers disclosed herein. are primarily intended for use for the purposes hereinbefore mentioned,
