,An. object of the ,inventionis to afford, a dis 'pensing attachment fora liquid container, said attachment andthe container being formed so as to be connected together and become'operable for withdrawal of small quantities of liquid from the container when the attachment is completely seated and securedon the container, and'become V inoperativewhen loosely orpartially connected.
fording a chamber 8 therein above the-neck of the'base, saidbore havingra-continuation 9 of reduced diameter that. extends-from said chamber through the top of thec'asing. In the lower end of the smaller bore'is securely positioned a tubular-valve seat! on which rests an outflow check-valvell that isnorm'ally closed. A second vtubular valve seat" 12 i securely positioned in the smallbo're in the casing :upon'which rests a second outflow check-valve I3 that is normally closed. The'lower' end of the tube l2 terminates at a point spac'ed fromthecheck valve ll and has made therein a notch Mwhereby the check- Another object of the invention is toprovicle 1 a dispensing appliance connected separably with a liquid container, bothof which are so constructed asto be .,co-operative when connected together, and .,.non-interchangeablex with other differently constructed similar appliances and containers, the purpose bein to circumvent use of parts of the instant invention indiscriminately with parts of other apparatuses l And a further object of the invention is the provision'of a dispensing. device having a suction tube and related parts arranged soithat when the body of the dispensing device is secured to a liquid container communication between the tube and the discharge channel of-the dispensing device is established to' render the apparatus operative. Other objects and advantages'of the invention appear in the following description; ,An illustrative embodiment of the 'inventioniis shown inthe'accompanying drawing, in which: Fig. 1 is aside'elevational view of a structure in which-the invention is incorporated, parts thereof being broken away; and v Fig. 2 is a similar view'of the dispensingappliance shown in Fig. 1, attached to a liquid container in operative position, portions being broken away; i I
The illustrative embodiment of the invention consists of a detachable dispensing device formed of a base member] having a tubular neck 2 and an internallythrea'ded lower end3 constituting a cap adapted to fit onto theexternally threaded. neck 4 of a liquid container 5, therebeing a vent opening S-made in the base that affords an inlet for airto the'container forthe relief of vacuum created therein as liquid from the container is withdrawn by the appliance.
Upon the neck 2.--is closely fitted a valve casing 1,- the lower end-portionpof, which has abor'e'iaf valve rl-l ispr'evente'd fromclosing the tube l2 when the check-valve I lis-unseated by outflow of liquidthrough'the tube- It]; 2
A'spout IEQp-reierabIy inthe'form of a gooseneck, issecur'ed' in the upper endof v the small herein the casing','its proximal end terminating at apoint above the check-valve 'l3,and-has .ma'de therein a notch I Bwhereby thecheck-valve I3 is prevented from closingtheispout whensaid check -v'alve 'l 3 is. unseated' by :outflow "of liquid thr0l1ghthe'tubel2.-
A'hollow stem I1 is secured in'oneuside of -the casing I that has communication with the bore of, the tube. I-2- through a passagewaygl8 therein, and the outer end of 'said stem has secured thereon a compressible bulb 19, upon manipulation 'ol which, altemateoutfiow through the spout and check-valvesl l an'd l3'takes place. i 1 I r r 'Theypassageway 'l8 inthe tube 12 is located preferably'at "a point above the axis of the'stem 12 so" that seepage of liquid fromthe bulbback into the tube'l2" is limited'and loss "of prime is thus substantially averted. This arrangement is desirable especiall'y'when the applianceis'=leftidle for a consi'derableperio'd of time between opery Preferably, a metallic band 291s disposed about the valve casing 1, through oneside' of which the stemiz l 1' projects, the'band "serving" as an orna-f mentation as well-as to strengthen the casing.'
'iA'suctlon tube 2| is provided forthe dispenser, the tube being 'positioned I so as to extend up through the bore of-the neck-210i the b'aserand' i'sprovided with a concentric h'ead 22 secured on itsupper end whichis surmounted by an 'aper tured gasket 23, th head and gasket being dis posed within the chamber '8 and axially movable therein. Upon the tube is loosely disp'osed a sleeve 24L the upper end of which has 'an' internal flange .25 "through which the tube 2 l loosely ex tends,.and a sh'oulder'26 on' the'tube'has engage;
ment with said flange, the shoulder being located on the tube at a point spaced from the head 22 so that relative axial movement of the sleeve and form ofa ihottle, tlrek neck of which is partially 4 closed by an integral choke 5' having a central opening 5" proportioned so as to receive loosely: therethrough the tube 2| when the dispensing appliance is in operative position on the con tainer. After the cap is screwed-down completely l protided'with a choke central opening, a dispenser having a vented base threaded to fit said neck, a valve casing secured concentrically on said base having an axial bore the lower portion 2 oi which forms a chamber, the upper portion of onto the neck of the container the sleeve24bears. upon the choke 5' thereof and exerts pressure against the spring 21 with consequent upward thrust of the head 22 and overlying gasket #3.;
