Cooper, Rahway, N. J assignor to, Standard Oil Development Company, a corporation of Delaware W Application' September 19, 1946, Serial Nb. 97,939 I The present invention relates to a "devicefor dispensing'fluids. More particularly'it relates to a device for dispensing fluids held under pressurein a sealed container.

It is an object of the invention to provide a comparatively simple dispensing device providing both a valve mechanism and perforating means which will permit connection of the dispensing device to a pressurized container for fluids withoutappreciable loss of pressure or contents during such operation, and which will permit controlled discharge of the container contents without substantial leakage. "It is also an objectbf the inventionto provide a convenient stand and holder for the container during use, and between periods of such use.

The invention" and 'its objects are fully set forth in the following specification and the accompanying drawings, in which:

Fig. 1' is a side nevanong aru in vertical section through one'form of the device, includ-' ing a fluid container. r

Fig. 2 is a' vertical section through the valve structure'and a fluid container along the. line 1141mm. Land j j u Fig. 3 is a side elevation, partly in'vertical section through an" alternate form of the device.

Referring specifically to the drawings, the numeral] denotes a holder-stand in which'is contained wave mechanism, includinga hollow valve body 2, having 'a; threaded nipple 3 extending upwardly from one end 'thereoffand pref erably integral therewith The nipple 3 is of less diameter than the body 2, thus forming a shoulder 2a at the base of the nipple. The nipple 3 is provided with a substantially conical perforator-tip 3a having a sharply pointed end. An annular washer 4 is supported on the'shoul-' der 2a. A' "passageway 3b opens outwardly through the tip 311, at one end, and extends into 2 Claims. (Cl. 222-82) DH the washer 4, sealingthe junctionof the icon tainerrand the valve body.

In order that the nipple"3 may adequately en gage'the bushing 6 before perforation of the head 5a by the perforator-tip 3a; it is essential that the depth of the bushing 6 be slightly greater than the length of the perforator-tip 3a. For exampla'if the perforator-tip 3a is "1% inch long, the bushing should be at least A; inch in depth. Thus'th'e nipple 3 may be brought into threaded engagement with the bushing before contact between the tip and the container head is positively established. t i In the'form of the invention illustrated by Figs. 1 and 2, a valve seat 221' is formed at the upper end of the hollow space in the valve body 2 at the junction of the passageway 3b therewith. The hollow space within the valve body 2 opens outwardly at the lower end.

Within the body 2 a spring actuated valve assembly'is'provided. A'stopper valve member I, held in a cup-shaped head 8 normally engages the valve seat 2b. Preferably the stopper 1 is communication with the interior ofthe valve adapted for threaded engagement by the'nipple 3 of valve'body 2, thereby accomplishing perforation ofthe'container head 5a by means of the of a resilient material such as rubber, either synthetic or naturaLand may be held: in place by inwardly crimpedportions of the head as at 1a. A helical valve spring 9 is disposed below the head 8,'he1d under compression between the head Band an annular spring seat'lil which in turn bears against an annular 'seal l I, the entire assembly being retained within the body 2 by means of the screw-slotted, annular retainer member 12 provided for threaded engagement with the inner wall of the valve body. A valve stem l3 having an enlarged portion or button |3a at its outer end extends through the retainer, seal, seat and spring into rigid connection with the head 8. The stem i3 is long enough to extend downwardly beyond the valve body.

To withdraw the stoppervalve 1 from engagement against the seat 21), thevalve stem I3 is drawn downwardly by means of a trigger [4 acting against the button 'l3a. The trigger is arcuately shaped, being provided with a slotted por- 2 tion 14a adapted to receive the extended porperforator-tip 3a of nipple 3. Complete engage mentof the nipple and bushing brings thebushbody. 2,:as by insertion of the opposed end portionsof element l5 into prepared openings or depressions in the body 2, and by the button |3a on valve stem l3 Providing for discharge of fluid from the container 5 through the valve body 2 is a discharge conduit l6, including a nozzle member |6a at its outer end. The nozzle lEa may be integrally formed, or, as illustrated, a separate element sweated, press fitted, or threaded into or around the conduit. Th inner end of the conduit opens through a lateral orifice through the valve body into the hollow space therein at a point below the valve seat 21).

In the form of the invention illustratedin Fig.

adapted to receive a differentty'pe ofc'ontain'e'r. As shown, the holder is provided with a sep- 1y greater than that from the forward end of the stand passageway to th rearward end of the chamber in valve body 2. Likewise, the limit of movement of the valve tube through the chamber of valve body 2 should be less than the front ,to-back'dimensionof the valve body. For example, if the distance from the forward end of the stand passageway to the rearward end of "tlie chamber in valve body 2 is 2 inches, the

arate standportion Ia. Other modifications of" I but the basic elements of the device accordingto the invention are to'be found in all forms illustrated. lIt-is"to be-;-noted also that 'each'o'f the two types of containers; 'the-ztwo types of holder-stands, and thetwo types or valves illustrated may be"-interchanged or recombined as desired; For example, "the Valve-as illustrated in Figs. 1 and Z'maybe substituted for thevalv'e illustrated in Fig.-3' and vice versa. Ililrewis'e'by suitable modification'of the conformation'of the upper-surface i of the respective holders, the containers of Figs; 1 and 3 maybe substituted one for another.

In the-device as shown in Fig.3, the hollow valve body 2 is provided with a laterallydisposed chamber, opening -rearwardl-y of *the" body through anopening in which isdisposed an annular seal M; and forwardlyofthe body through-a restricted openingformed by an annular shoulder |-8 against 'which -is disposed an annular seal IS. The passageway 317 extends angularly through the nipple 3'and-tip 3a' communicating with the valve ohamber'at its lower end. A distributor ring 2-9, forming the fixed element of a sliding valve assembly islocated substantially centrally' of the valve'chamber, between 'the two annular sea'l members, Il and H3. The distributor member may'beof any convenient form which will provide an annular space between the'ehamber wall and the member,an1d afford clos'e sliding contactinteriorly with a movable discharge tube 2|. As shown, the member-2'3 is in one piece, having ports; Zlla opening through the member 20, into the annular space aroundit.

The discharge tube-2| is of a length-slightly greater than that of the upper portion of the holder-stand I, and extends through a passageway formed in the stand concentrically with the chamber of valve body 2. This passageway is enlarged stepwise, at its rearward end to receive an annular retainermember 2'2 having-a flanged end22a providing an annular seat for the helical valve actuating spring 23. An enlarged operating button 24 closing the rearward'end-of the discharge tube 21 provides abearingsurface for the outer end of the spring 23. Thespring 23 is held under slight compression between the retainer flange 22a and the button 24 by means of a flanged nozzle tip 25 for the forward end of the tube 2|, the flanged portion'of the tip 25 engaging the surface of the holder-stand One or more valve ports Zia are provided in the tube 2| preferably by drillingthe tube and deforming inwardly the edges of the drilled opening. The ports 2| a should be spaced from the forward end of. the tube at a distance slightdistanceof, the port or ports 2|a from the forvwafrd end of tube 2| should be approximately ,2 inches. Also, if the front to back dimension of'the valve body 2 is /2 inch, the limit of iiiovementoffth'e valve tube through the chamber ofv'alve body?2should be about 3% inch.

In using the-dispensing device illustrated, and described above,.-the--container 5 is attached to the holder-stand by, means of the threaded nipple '3 on valv body 2, and the threaded bushing 56 on the container. By means of the container; the bushing't 'is -threaded on the nipple 3'=un'til a tight 'seal iis'made'i between "the-bushing. and *washer 4'. At that-point,-the-perforatortip 3a will have rupturectthe; container head- 5a permitting passage of fluid into the passagvfalyfib. r

In the form of the deviceillustrated-by Fig-n 3, forward pressure against the operating-button- 24 will move the-discharge tube ZI torward through the distributor-ringfiltandthe passageway-in the-stand l' to a point where port or ports 2 la open into the space formed-by-the distributor ring- 20; or into apposition with the ports- 20a, permittin fluid to 'flow through the passageway 3b and the valve chamber into the discharge tube 2| and outwardthrough-nozzle-25. When pressure on the' bu-ttorr 2 |-is"released, theactuating spring '23 will withdraw the-discharge tube-1| from-its extended position, and thereby theport or. ports2|a= from access 'to the spacewithin'the distributor ring or apposition withportsllla, shutting off the flow; of fluid through thedischargetube zl and nozzle 25.

Although the invention has been descrlbeiwithreference to itspreferredembodiments, -it is to be understood that various modifications and alternate arrangements are :possible 'without departing from the inventive concept disclosed. It is not'intended that-the invention-shall be limited by such specific descri-ptiomor 'illustration zprovided for the purpose of 'disclosure, but-onlyby the appended claims;
