9 Claims.

The present invention relates to improvements in valved dispensing caps or heads for siphon` or pressure bottles of the type commonly used for carbonated liquids.

An object of the invention iS the provision of a Siphon head of attractive design, which readily lends itself to comfortable single handed dispensing koperations and further embraces novel features of safety. l

Another object of the invention is the provi- Sion of a Siphon head in which the actuating mechanism is entirely enclosed, thereby eliminating possible premature discharge of the contents.

A further object of the invention is vthe provision of a siphon head which may be formed of any material suitable for die casting into which portions formed of a non-corrosive metal may be inserted.

A still further object is the provision of a siphon head which is readily demountable, the

valve mechanism being rendered easily accessible by removal of the head from the bottle.

Other objects andfeatures of novelty will be in part apparent and in part pointed out during the course of the following description.

In the drawing:

The usual Siphon head construction embodies a neck-like portion extending above the body of the head and having an outwardly extending operating lever connected thereto. The usual siphon head mechanism receives much hard usage which sometimes damages the relatively soft metal of which the heads are constructed. Filling bottles having weakened heads with highly charged liquids creates the danger of exploding during both illing and using. In the present construction I have provided means for completely enclosing the operating mehavnism in a manner to prevent damage thereto. Such construction lends itself readily to easy manipulation.

Referring to the drawing and Fig. 2 in particular, the Siphon head comprises a body portion Ill which may be formed of any material suitable 5 for die casting. In general practice siphon headsV are .manufactured from a material which is impervious to the corrosive effect of the usual content of the bottle. Such material is relatively expensive. With this feature paramount, the 10 present construction provides for only those surfacesin direct contact with the contents having a protecting covering of a more expensive noncorrosive material such as block tin, as will be more fully described presently. 15

The body portion Ill is provided with a depending annular attaching flange II or skirt having internal screw threads I2 adapted to engage an exteriorly threaded split attaching'ring I3. The ring I3 is provided' on its inner surface with an 20 annular bead I4 for engaging the shouldered finish I5 of the usual siphon bottle. In securing the head to the bottle, the usual delivery tube I6 carried by a stopper I1 is placed within the bottle. An annular ange I8 on the stopper ex- 25 tends over the sealing surface or rim of the bottle and provides a seal when the head is secured in place. The split ring I3 is placed about the neck of the bottle and brought into threading engagement with the threaded ange Il where- 30 upon rotationof the head and ring in opposite directions causes the bead Id'to be drawn against the shoulder I5, thereby compressing the flange I8 between the rim of the bottle and the Siphon head to form a gas-tight seal.

' A hollow housing I9 extending upwardly from the body I0 provides a cylindrical chamber 20 within the body in axial alignment with the ange II and bottle opening, into which the valve mechanism is tted. An outwardly and downwardly curved spout 2| formed'on one side of the head is provided with a passageway 22 which is in communication with the chamber 20 and serves for filling the bottle and discharging the contents thereof in the usual manner.

A liner 23 formed of block tin or a similar non-corrosive metal in the form of an inverted cup, is forced into the chamber 20, the wall sur' rounding the open end of said cup being flared outwardly at 24 to form a flange against which the flange I 8 of the stopper Il' bears when the head is assembled on the bottle. A liner 25 of Similar material within the passageway of the spout is suitably connected to the liner 23, thereby preventing any possible contact of the gas or 55 liquid with metal which would have an injurious eect thereon.

The valve mechanism comprises a stem 26 or headed bolt which projects into the chamber 20 at right angles to the vertical axis thereof through an opening 2l in the wall of the housing I9 and liner 23 diametrically opposite the passageway 22 of the spout. The inner end of the stein is provided with a head 28 threaded thereon which carries a seating member 29 for closing the passage 22. head 2B by a beveled tongue and groove connection 29a and is readily removable should it .become worn and fail to properly close the .passage 22. The valve head is maintainedin seatingposition by means of a spring member 3Q shown as being formed of resilient rubber and disposed about the stem 26 between the head andY walll of the chamber. gasket around the opening 2l and prevents the escape of pressure therethrough.

Means forA operating the valve mechanism comprises a covert! or hollow shell shaped longitudinally to .conform with the body portion and substantially rectangular in cross-section. Figs. l, 5 and 'l illustrate the general conformation of the cover. The cover is provided at one end with a depending apron 32 having an aperture 33 near its upper end 4forthe reception of the spout 2l. The lower end. of the apron is curved horizontally to conform generally withthe diameter of the skirt Il and provides a finger gripping surface whereby the valve may be operated. When the valve is in closed position. the apron is spaced l from the body of the head to permit suincient operating movement. A filet 32 formed on the apron beneath the opening 33 extends outwardly in the direction of the spout and provides a linger guard which prevents pinching the ngers between the apron and `spout as the cover returns to the closed position.

The cover 3| is adapted for limited sliding movement longitudinally of the spout and is provided with a pair of vertically disposed parallel bearing surfaces 35 within the cover on each side thereof adapted to bear against corresponding surface 3S formed on either side of 'the housing I9. The bottom edge 3'! of the downwardly extending sides of the cover 3l lies in matched relation with an upwardly facing surface 38 formed1 onthe'bodyA Iii. The meeting line of the surfaces 3l and 38 lies in the plane of the valve stern .26, the juncture of body IE! and cover 3| on the side opposite the spout forming a well to permit free movement .of the outer end of the valve stern. The'valve is actuated by means of a lug 4U extending downwardly into the path of the stemuiZE and having a bifurcated end 4I 'or fork which straddles said stem and bears against the head thereof.

The cover 3l `is held in place by a retaining screw 42, threaded into a boss formed on the body Ill, and a slot 43 in the cover 3l. Anopening Mis provided opposite the head of the valve stem, and in alignment therewith to permit easy adjustment thereof;

When it is desired to discharge the contents of the bottle the bottle may be grasped around the neck, the 'fingers overlying the apron beneath the spout and suicient pressure exerted to move the apron toward the flange ll. 'This movement of the cover 3! causes the valve stem 2S to be drawn outwardly, thus placing the chamber 20 in communication with the spout 2 l Such movement of the cover is illustrated by dotted lines in Fig. 5,

The member 29 is secured to the.i

The rubber further servesas a.-

It will be noted that the valve member 29 may be readily removed and replaced without dismantling the head or removing other parts thereof. Further, the entire valve unit may be replaced without disturbing the cover. These and other features produce a simple and economic article embodying a wide margin of safety by the elimination. of the usual projecting operating lever.

Modications may be resorted to without departing from the scope of the appended claims.
