(Cl. 22S-22) connector-cap adapted to lock the device to the bottle, and more particularly to the'cap of the bottle. v i i Fig. 'l is a vertical section onthe same scale as Figs. 3 and 4, showing amodiediorm of connector means.
Referring now more particularly to the con i struction of the device andthe co-relation of the yparts forming the same, thereference numeral 8 designates an ordinary bottle ot the type usually containing charged waters or charged bevf erages of various kinds; and applied to the neck 9v of the bottle is a suitable closure, such as commonly provided in bottles used for charged waters or beverages. comprising a metallic cap I0 clinched in the usual way underneath a rib or flange Il formed at the upper end of the neck. Between the metallic cap and the neck of ythe bottle, a cork or other washer 0rv sealingdisk I2 is interposed so that a perfect seal'is provided for the bottle which will guard against the escape of the carbonio-acid gas with which the liquid in the bottle is charged. y My improved dispensing device or Siphon, as it may be termed, comprises a discharge or dispensing tube i3 whichhas secured toits upper end a: valve casing I4, and near its lower end is slightly enlarged, as at `I5,and` tapered from said enlargement to a point i6 which serves as a piercingv element for the tube. The enlarged tapered lower end of this tube is provided with a plurality lof liquid inlet-openings l1, and the upper end of the tube is threaded into the valve casing M, as at I8. n
The valve casing may be a die-casting, or it may be otherwise constructed, and -it comprises an outer shell I9 which is cylindrical at one end extending 4from the tapered portion is a discharge tube 2| having 'a discharge-opening 22 directed downwardly.V This casing includes a cover 23 at its cylindrical end'which is removable so that access may behad to an inner shell 24,'.preferably concentric with the outer shell and formed in piece therewith through a'r boss-like connection 25 into which'the discharge or dispensing tube i3 is threaded. i
'Ihe inner shell 24 4also includes a `cover 26; both covers `2i! and 26 being preferably threaded in place so that they canbe easily unscrewed to gain access to the interiorof each shell,Y or chamber, as each maybe termed. `A largefopening 21 is formed axially' inthe cover-26, which is normally closed by a valve 28 bearing against the inner side of said cover and having a valve-stem 29 extending through the opening 21 in the cover 26 and outwardly beyond the cover 23.
Within the inner chamber 24 an expansion spring 30 is arranged, one end bearing against the 5 end of said casing distant from the cover 26, and the other against the valve 21 so as to normally maintain said valve rmly seated against the inner side of the cover 26 and effectively seal the opening 21 in the latter. Extending outwardly from the cover 23 is an ear 3| to which is pivotally secured a lever 32 which bears against the end of the valve-stem 29, and upon being swung inwardly towards said cover causes movement of the valve-stem 29, which will compel the valve to be unseated and uncover the opening 21 in the cover 26.
From the foregoing it will be apparent that the discharge or dispensing tube I3 opens directly into the inner chamber 24 of the valve-casing I4, and it is to be noted that the inner chamber is separated from the outer casing by an annular intervening space 33, except for the boss 25 connecting the peripheral wall of said inner chamber with that of the outer chamber.
'I'he connector means utilized to connect the device to the bottle comprises a connector-cap 34,
the lower portion 35 of which is cylindrical and hollow and has an internal diameter slightly larger than the diameter of the conventional metal cap employed on charged water or beverage bottles, so that it may be placed directly over and around the cap. This cylindrical lower portion is connected with a cylindrical portion 36 of smaller diameter near the upper end of the con- 35 nector-cap by a tapered portion 31, and at the upper end of this smaller cylindrical portion 36 the connector-cap is further reduced in diameter and provided with external screw-threads 38, for a purposeto appear hereinafter.
The connector-cap 34 has an axial bore 39 formed therein which extends from the hollow of the cylindrical lower portion 35 upwardly to the upper extremity of the cap, and this bore is enlarged or counterbored at its lower end, as at 40. Arranged Within the hollow cylindrical lower portion 35 of the cap is a sponge-rubber or other suitable packing 4| in the form of an annulus, the axial opening 42 therethrough being preferably of the same diameter as the enlarged lower end of thebore 39, the upper wall of the hollow portion of this cap serving as a backing for the sponge-rubber or other packing. This packing is pressed into the hollow portion of the connector-cap and retained therein by its inherent resiliency.
'Ihe peripheral wall of the hollow cylindrical lower portion 35 is slit from its lower edge upwardly, as at 43; four such slits being provided, but any other number may be employed. These slits are preferably of elongated V-formation, and
the outer surface of said peripheral wall is provided along the regions of these slits with screwthreads 44.
The connector-cap is'formed of material possessing a certain degree of resiliency, the peripheral wall surrounding the hollow lower portion thereof being flared outwardly slightly, as illustrated in Figs. 4 and 6; and it also has at its lower edge, preferably between the slits formed therein,
inwardly-curved retainer lugs 45.
Fitted over the connector-cap 34 is a securing member 46 which is hollow and comprises a cylindrical lower portion 41`adapted to surround the slited cylindrical lower portion 35 of the connector-cap, a second and smaller cylindrical member 48 connected to said cylindrical lower portion 41 by a tapered portion 49, which tapered portion conforms to the tapered exterior of the tapered portion 31 of the connector-cap. The upper cylindrical portion 48 of the securing member is slidably arranged on the cylindrical portion 36 of the connector-cap, and said securing portion is therefore both slidably and rotatably mounted on the connector-cap.
The peripheral wall of the cylindrical portion 41 of the securing-member is internally screwthreaded along its lower region, and these screwthreads are designed for threaded engagement with the external screw-threads 35 on the connector-cap. When these threads are brought into engagement and the securing member 46 rotated and lowered on the connector cap, the slitted outwardly flaring portion of the peripheral wall 44 of the connector-cap is forced inwardly, with the result that the inwardly-curved retainer lugs 45 are brought underneath the lower edge of the flange of the capv III and are firmly forced into contact therewith so that when said securing member is firmly tightened, thepossibility of disengagement of the connector member fromfthe bottle, and more particularly from the cap of the bottle, is entirely eliminated.
It may here be stated that while the securing member is being tightened around the connectorcap, the latter is pressed downwardly, with the result that the sponge-rubber or other packing 4| therein is brought into firm-contact with the upper surface of the sealing cap I0, causing compression of said packing in the Vdirection of the axis thereof and radial extension so as to effect a tight seal at all of its exterior surfaces. It is also to be noted that as the inwardly-curved retainer lugs are forced into firm contact with the lower edge of the sealing cap by the securing member 46, the concaved or inwardly-curved inner surfaces of said lugs tend to draw the connector-cap downwardly over the cap to more effectively act upon the packing.
While connecting the device to the bottle, the discharge or dispensing tube 3|, which is carried by the connector cap due to the frictional contact between the two, is drawn upwardly to being the enlarged lower extremity thereof into the enlarged lower end of the bore 39 and into the axial opening formed in the packing 4|, as clear- 1y shown in Fig. 4, and in this position the pointed extremity of said enlargement is axially in contact with or in close proximity to the sealing cap. Therefore, after the connector-cap is rmly secured in place by the securing-member, the lower pointed extremity `of the discharge or dispensing tube I3 is forced through the sealing cap and the cork or other washer I2 within the cap, and the tube then lowered into the bottle to assume the position shown in Fig. l.
As clearly shown in Fig. 3, the connector-cap is in firm engagement with the sealing cap I0 of the bottle, it being so retained by the securingmember 46, and the sealing cap I0 and cork or other washer or disk I2 are pierced, as indicated at 50. Although the opening formed by piercing thesealing cap and washer would in mostl instances provide an axial opening in the cap somewhat larger than the discharge or dispensing tube, it is to be noted that the sponge-rubber packing 4I will have been previously rmly pressed against all surrounding surfaces, with the result that there will be nov possibility of leaklage of carbonic-acid gas from-the bottle, nor any pass underneath the edge of the sealing cap at leakagev of liquid even though the `bottleis inverted'.'
As'statedthe.discharge or dispensing `tube I3 extends upwardly through `the connector-capand vwithinthe bottle, this `being guarded to guard against the escapeof Vcarbonio-acid gasl `along this tube as well .as to increase friction betweenthe two', I thread a packing nut orV cap 5I onto the external screw-threads 38 formed on the reduced upper extremity of` the connectorcap, `andibetween the two clamp suitable packing 52 which isirmly 4compressed around-the tubey v"I3, yet permits the tube tobe slid under force ywithin the 'connector-cap. i
With the parts arranged as shown in- Figs. l, 3, and 5, the device will be firmly attached to the bottle to'prevent the escape of any pressure from against by the packing 4I in-the connector-cap, therpacking 52 around the tube `I3, and the valve 28 in the valve-casing I4. The pressure within the bottle will have caused liquid to pass through the discharge or dispensing tube I3 and enter the inner chamber 24 of thevalve-casing, where it is held against escapebylthe-valve 28.- When itisdesired. to dispenseanyquantity of the liquid, it `is simply necessary to press Athe lever 32,` whereupon the valve28 will-be opened and a continual flow of liquid take place through the valve open- While I `have thus far `ing 21 and the outer chamber I9, sothat it may be discharged through the discharge opening 22 into a glass orv other desire-d receptacle placed applied to the lever 32will immediately cause the sprng 30 toclose'the valve 28 and prevent ,any further escape` of liquid from the bottle. liquid remaining in thebottle will be maintained under pressure and therere be kept in perfect condition until the contents of the bottle is fully discharged, regardless of the number of times the,
act of dispensing the liquid has taken place.
` which I now prefer to employ for securing the device to the bottle, this may be accomplished in haveillustrated various waysand inFig. '7, I a modicationof the connecting means illustrated in the. preceding figures oi the drawing.
and packing I2 are Inlthismodiiication, although the sealing cap III pierced in the same manner as described with reference to the constructions disclosed in Figs. 3 and 4, I reduce Vthe length of the connector-cap so that theperipheral wall thereof encircles the upper vportion only of the sealing cap, III.; The said peripheral wall is continuous circumierentially, and therefore the slits y 43 illustrated in thepreceding `iigures are dispensed with, since itis not necessary in this modified construction to provide `any resilient portion for the kperipheral wall.` y
i The upper portionofthe connector-cap is reduced in'length and the hollow securing-member 46` dispensed with. In lieu ofthe latter, I secure a yokearm 53 between a shoulder 54 on the connector-cap and the packing nut or cap 5I; the arm extending outwardly in opposite directions and having lock members 55 pivotally secured to their outer ends. These lock members are disposed at dia-metrically opposite sides of the conhector-cap, and at their lower ends are curved inwardly and upwardly, as at 56, thereby forming lock-hooks adapted to engage underneath the flange of the sealing-cap Ill.` In order to engage these lock members, and more particularly the lock-hooks thereof with the sealing cap, it is necessary to depress the connector-cap 34 sufficientlyto have the extremities of the lock-hooks p ing the connector-cap Any described the meansrinner chamber having a position the extremity of the lock-hooks between the free lower marginal portion of the sealing cap and the neck of the bottle. When depress- -to engage the said lockhooks with the sealing cap. the sponge-rubber packing 4I, preferably usedA in this modification, will become depressed, and upon relieving pressure, compression on the packing will be relieved to a certain extent, yet sufficient compression of thev packing will be retained to assure a tight sealing of the bottle at this point, and the packing will also serve to maintain the locking members in locking condition Without the possibility of accidental disconnection of said lock members `being made from the bottle-cap, since a direct axial pressure on the soft sponge-rubber in a downward direction will be required to release the device from the bottle. p
From the foregoing it will be understood that the various parts of thedevice form a unit bodily applicable to and removable from the bottle, and that the parts of the device below the valve casing I4 are carried bythe tube and serve to attach the tube to the bottle with the lower portion of the tube entered in the bottle and ythe i upper portion projecting upwardly therefrom.
