RECEPTABLE CLOSURE AND DISPENSNG DEVICE Filed March 4, 1936 l 111111 la I INVENTOR. F G. /Qo/QMS ATTORNEYS Patented 19, 19x38 UNITED STATES PATENT oFF-ICE Ferdinand GL Adams, Maplcwood,f. J. Application March 4,1936, 'serial No. s'ztooo 4 Claims.

This invention relates to improvements in receptacle closures and dispensing devices used in conjunction therewith, and has particular reference to a closure and cooperating dispensing 5 device applicable to receptacles, such as bottles, for containing liquids under gaseous pressure.

An object of the invention is to facilitate the discharge voi liquid under pressure from a container with a minimum loss of said pressure, by

l0 utilizing, in combination with a closure cap for the container which may remain permanently aiiixed thereto and which effectively seals the same against the escape of such pressure, a. dispensing device having a nozzle made to penetrate said closure cap when discharging some of the contents of the container through said nozzle, and which is removable from said cap at the conclusion of the discharging operation to permit the cap to again seal the container.

Another object is to provide an improved device for dispensing the contents of a bottle without removing the closure cap thereof, and in which a nozzle' of said device is designed to readily penetrate said cap preparatory to discharging 2 5 said contents through the nozzle after which the device may be withdrawn from the closure cap without further discharge of any of said contents.

The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawing which illustrates preferred embodi` ments of the inventive idea.

In the drawing:

Figure i is a vertical sectional view through a closure cap constructed in accordance with the present invention and showing the same ailxed to the neck of a bottle, a dispensing device, shown partially in elevation and partially in section,

being also illustrated in a position just prior to penetration of the closure cap by said device.

Figure 2 is a view similar to Figure 1 illustrating the dispensing device in its operative position with a portion of the nozzle thereof projected through the closure cap and into the neck of the bottle.

Figure 3 is a view similar to Figure 1, illustrating a different form of closure cap and dispensing device.

Figure 4 is a similar view illustrating the fully operated position of the dispensing device of Fig. 3.

Figure 5 isa bottom plan view of the resilient washer forming a part of the closure cap.

Figure 6 is a fragmentary vertical section show- (Cl. v225422) ing the nozzle of the dispensing device in a partially'operated position.

Referring more particularly 'to the accom-panying drawing, the'numeral 6 indicatestheoutlet end of the neck of a receptacle such as a bottle IS of the type 'commonly employed for containing carbonated beverages and the like, the discharge opening for'said bottle being closed by a metal cap 1. This cap may take the form of bottle caps now extensively used, in which the edge of the 10 cap flange is crimped as indicated at Il for secure attachment to the bottle and may be applied to bottles without altering the usual capping machinery. In accordance with the present invention and as illustrated in Figures 1 and 2, the 15 described in more detail. In place of the ordipreferably in the center thereof with a small opening 9 of a diameter suilicient to receive an end of nozzle I0 of a dispensing device later to be described in more detail. In place of the ordi- 20 nary cork washer commonly employed with caps of this type, the present invention contemplates use of a resilient washer II made of a suitable rubber or like material. This washer is substantially flat and is of a ydiameter approximating 25 that of the interior of the cap l, and is designed to seat snugly against the interior surface of the central or closure portion of the cap so as to provide an effective seal for the opening 9. Preferably, though not necessarily, the central por- 30 tion of the washer I I may be enlarged on one surface thereof as indicated at I2 and this enlargement may take any desired form. Through the center of this enlargement there is provided an opening I3 of pinhole size which is normally 35 closed by the contraction of the material of which the washer is made and this closure is further aided by pressure against theenlargement of the gaseous fluid within the bottle 6. In the manufacture of this washer, the opening I3 40 may not necessarily be formed therein in which event reliance may be placed upon the nozzle I0 to provide the opening when said nozzle is initially inserted through the cap. When formed in the washer, the opening I3 aligns with the op- 45 ening 9 in the metal cap so that the nozzle will be directed into said opening when inserting the same through the cap. If desired, a thin exible disc Il of foil or other suitable material and of a diameter substantially equal to the washer II, 50 may be inserted into the cap before the latter is applied to a bottle and after the cap is ailixed in vposition said disc will eifectively cover the adjacent surface of the Washer I I and, besides forming an additional seal lfor the opening I3 to in- 55 sure against any possibility of escape oi' contents of the bottle before use, said disc Il will also protect the washer against any chemical action that the contents of the bottle might have on the material of which the washer is made. When the cap 1 is in position, the washer II and disc Il at their peripheral portions are securely held between the cap and the end of the bottle in the customary manner. The bottle is thus securely sealed and `will remain so as long as the cap 1 is affixed thereto` except for the intervals when the dispensing device is inserted through the cap for the purpose of discharging some of the contents of the bottle.

The dispensing device shown in Figures 1 and 2 comprises an elongated tube constituting the nozzle I0 and said tube is bent intermediate its ends as indicated at I5 so that the contents of the bottle may be discharged into a glass without inverting the bottle to an absolute vertical position. The inner end of the nozzle IB is preferably pointed as indicated at I8 to facilitate its projection through the closure cap and one or more small openings I1 are provided in said pointed end for permitting the contents of the bottle to pass into the nozzle. At an intermediate point of said nozzle between the bend I5 and inner end I B, the same is provided with a nger grip which extends longitudinally of the nozzle and is sufficiently long to permit the same to be readily grasped between the fingers and thumb when inserting the nozzle into the bottle.

'At the inner end of said grip I3 the same is provided with a rubber washer I 3 which acts as a stop to limit the inward movement of the nozzle when being inserted into the bottle and which seats against the cap 'I so as to effectively 'close the opening 9 to prevent any possibility of escape of the contents of the bottle through said opening when discharging the contents.

In practice, when it is desired to discharge some of the contents of the bottle, the latter is first inverted so as to leave no air space between the liquid and disc I4 and the pointed end of the nozzle I0 is then inserted through the openings 9 and I3 and upon further inward movement the end I6 then punctures the disc Il. As the nozzle penetrates the washer it expands the opening I3 and distorts the portion of the Washer immediately adjacent said opening so that the natural tendency of the material of the washer to' contract causes it to snugly fit around said nozzle while the latter is in its penetrating position. 'After the nozzle has been forced inwardly until the washer I! has contacted the cap 1 as shown in Figure 2, the bottle continues to be held in its tilted or inverted position until a sufficient amount of the contents has been forced outwardly through the nozzle by the pressure within the bottle, whereupon the nozzle may be withdrawn or detached from the closure cap with the bottle still in an inverted position, thus avoiding any possibility of the gaseous fluid within the bottle passing through the nozzle, as it would do if the bottle were first righted and the nozzle then withdrawn. In Figures 3 and 4, a slightly modified form of closure cap 'I is provided in which, instead of forming the opening 9 as in Figure l, the cap at its center is weakened by scoring the same as indicated at 20 so that it can be readily penetrated by the pointed nozzle of either` the dispensing device shown in Figure l or that shown in conjunction with the cap of Figure 3. 'Ihe resilient washer 2l in the latter figure is substantially the same as the washer II except for slight alteration of the connguration of the enlargement 22 in which the opening 23 is formed in alignment with the scoring 20. Also in the modication being described the use of the inner sealing disc I4 is discarded. v

The dispensing device oi Figures 3 and 4 comprises a metallic base 2l having an annularY flange 25 which forms a recess of a diameter substantially equal to that of the cap 1 so that when the device is applied to the bottle it will engage said cap with such friction to hold the device in position but permit of a ready removal thereof when it is desired to utilize the device on some other bottle. The base 2l is also provided with a lateral extension 2B forming a tubu lar casing closed at one end except for an opening to receive the tubular nozzle 21 so that said nozzle is slidably mounted within said casing, with the outlet end projecting therefrom. Said nozzle at its inner end is pointed as indicated at 28 for easy penetration of the cap 1 and washer 2i and the portion of said nozzle within the extension 2B is provided with a washer 29 which acts as an abutment engageable with the closed end of the casing 25 so as to limit the outward movement of the nozzle. Adjacent its outer end the nozzle 21 is bent as indicated at 30 and contiguous to this bent portion there is secured to the nozzle a disc 3I and finger piece 32, the latter being employed as illustrated in Figure 4 to depress the plunger 21 when causing it to penetrate the closure cap, and the disc 3I providing an abutment for one end of coil spring 33 which is introduced between the base 24 and disc 3| and surrounds the extension 26. Said spring acts to yieidably maintain the nozzle 21 in a retracted or normal position with respect to the cap 1 and when inward pressure is exerted upon the nozzle said spring is placed under tension so that it will afterwards act to withdraw the nozzle from the operative position of Figure 4 when pressure thereupon is removed at the termination of the discharge operation of the contents of the bottle.

In Figures 3, 4 and 6, provision is made whereby the quantity of liquid flowing from the bottle 6 may be regulated. To this end, the inner end of the nozzle I0 may be provided with two or more longitudinally spaced openings 3l and 35 each communicating with the duct extending through the nozzle and each of a size less than the cross sectional area of said duct. With this construction, when the nozzle is inserted through the cap 1l and washer 2| to the position shown in Fig. 6,

f only the opening 34 will be immersed in the liquid while the opening 35, then disposed between the surfaces of the washer, will be closed by the latter and no liquid will pass therethrough into the nozzle. Thus, a quantity of liquid, less than the capacity of said duct, will flow through the opening 34. Should a more rapid flow be desired, it is only necessary to project the nozzle further into the bottle as shown in Fig. 4 so, that the opening 35 will be uncovered, whereupon liquid will flow through both the openings 3l and 35.
