- CAPTIVE RECEPTACLE CAP Filed May 15, 1935 V6/"ence M Jones INVENTOR Patented` Nov. 10, 159367- UNITED STATES PATENT OFFICE CAPTIVE RECEPTACLE CAP' Clarence M. Jones, Tulsa, Okla.
Application May 15, 1933, Serial No. 671,235
2 Claims.
I'he invention relates to receptacle caps` of the ty-pe threaded on the neck of a receptacle and provided with a discharge port, with which a valve carried by the neck cooperates when the cap is screwed to closed or open position, and has for its object to provide a split ring disposed within grooves in the inner periphery of the cap and in the outer periphery of the neck and playing between the shoulders formed by the grooves for limiting. the axial movement of and preventing its entire removal from the receptacle neck.
A further object is to taper the upper shoulder of the receptacle neck groove so that when the cap is unscrewed, said tapered shoulder will have a spreading action on the split ring against the lower shoulder in the groove in the inner periphery of the cap, thereby preventing contraction or expansion of the ring and particularly the dropping downwardly of the ring on the receptacle neck.
A further object is to make the groove in the inner periphery of the cap of sufficient width whereby its upper shoulder will not engage the ring when the cap is screwed to closed position, thereby insuring a proper seating of the valve in the valve seat of the cap.
A further object is to provide the receptacle neck with an annular member encircling the same and having an inturned ange engaging the end of the neck and a packing member, which flange terminates in a V-shaped return bend, terminating in an apertured diaphragm carrying the valve. Also to provide a valve seat or shoulder within the cap and cooperating with the V-shaped return bend for contracting the same and insuring aproper seating of the valve at all times and an inward and downward pressure on the packing member, as well as allowing the valve tor flex the apertured diaphragm portion thereof so that said valve will vaccommodate itself to the valve seat.
A further object is to provide the receptacle neck groove portion, which is tapered, with an annular groove in which one side of the split ring is received when the cap is screwed to its outer position, thereby preventing displacement or slipping of the ring in either direction.
With the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawing: 'p
Figure 1 is a vertical' transverse sectional view through the receptacle neck and cap, showing the split ring on the neck and the cap in position to be threaded on the neck for contracting the ring so that it will spring into the groove of the cap.
Figure 2 is a view similar to Figure 1 showing the ring contracted and. on the lower shoulder of the cap groove.
Figure 3 is a view similar to Figure 1, but showing the cap in closed position and the split ring expanded into the groove of the cap for preventing removalv of the. cap beyond its open `and closed position.
Figure 4 is a vertical transverse sectional view through the cap and receptacle neck showing the cap in its extreme open position.
Figure 5 is a perspective view of the receptacle neck andthe device applied thereto.
Figure 6 is a modified form of the device showing the entire receptacle neck formed from sheet metal, and a structure particularly adapted for use in connection with metallic receptacles.
Figure 7 is a top plan view of the receptacle 25 neck.
Referring to the drawing, the numeral l designates the neck of a receptacle, for instance a bottle and 2 the cap. The outer end of the cap is provided with a discharge port 3, which, when the cap is in open position as shown in Figure 4, allows discharge of the contents of the bottle 4 by a shaking or pouring operation. When the cap is in closed position the hollow valve 5 is seatedv in the valve seatv 3 of the cap and seals the 35 device.
In devices of the particular type where the contents of the receptacle is discharged through a port inv the cap, it is highly desirable to provide means whereby the cap will be prevented from 40 being screwed entirely from the receptacle neck, and to accomplish this result an expansible split ring 6 is provided in the groove l in the outer periphery of the neck l, and which ring is of greater outer diameter than the groove 1, whereby it will extend into the annular groove 8 in the relatively wide annular groove in the inner periphery of the cap 2. By providing a relatively wide groove 8, it is obvious the split ring 6 will play between the shoulders 9 of the groove 8, 5 thereby allowing a relatively long range of movement of the cap 2 and at the same time when the cap is in closed position as shown in Figure 3, the upper shoulder 9 will not engage the split ring 6, therefore it will not interfere with the seating of the valve 5 in the valve seat 3. Neck I, below the annular channel 'I and the square shoulder I0, formed thereby, is threaded as shown at II, and the lower end of the cap is threaded thereon at I2. Above the threads I2 a tapered shoulder I3 is provided within the cap, which, when the cap is screwed onto the neck during an assembling operation with the split ring 6 on the neck, will contract the ring.
During the assembling operation as the cap is screwed onto the neck I as shown in Figure l and tapered shoulder I3 contracts the ring, the continued screwing on of the cap 2 will allow the ring to spring over the lower shoulder 9 of the cap into the annular groove 8 within the cap. This movement is illustrated in Figure 2 of the drawing. Figure 3 shows the final stage of the assembling operation with the split ring in the channels 6 and 8 and with the cap in closed position. The upper portion of the neck and channel 'I therein tapers upwardly and outwardly as shown at I4, therefore it will be seen that said tapered portion will cooperate with the inner periphery of the split ring when it is moved up during the cap opening operation and in cooperation with the lower shoulder 9 of the channel 8 will positively grip diametrical sides of the split ring on its inner and outer peripheries, thereby positively holding the ring against contraction or expansion so that it can form a positive lock and a non-jamming one. The tapered portion I4 is preferably provided with an annular groove I5 which receives the inner periphery of the ring and forms a relatively wide seating surface for the ring on the neck. It will be noted that the annular groove 1 in the neck I is relatively wide in relation to the ring as well as the groove B in the cap, therefore it will be seen that by allowing movement of the ring in the neck and cap, axially, during the movement of the cap to open position, the relatively long range of movement is obtained for the cap for a maximum unseating of the valve 5, thereby allowing freedom of discharge from the receptacle or bottle.
The upper end of the neck I has crimped thereon a sheet metal casing or ring I6, which is provided with an inwardly extending flange I1 engaging the packing I8 on the upper end of the neck, thereby forming a leak proof connection. Flange Il is provided with an upwardly extending ange I8a terminating in a downwardly extending portion I9 having an apertured diaphragm 20, through the apertures of which liquid dispensed flows. Struck upwardly from the apertured diaphragm 20 is the valve stem 5, which cooperates with the valve seat 3 in the cap 2. It will be noted that all of these parts are made from sheet metal, hence the diaphragm will flex upon the seating of the valve, thereby insuring a positive seating of the valve at all times. As the cap 2 is screwed to closed position as shown in Figure 3, the upper edge 2I of the flanges i8a and I9 engages the curved seat 22 in the cap, thereby flexing these parts and insuring a leak proof connection between the cap and the flanges I9 and Illa, and at Jthe same time seating the apertured diaphragm 2U on the washer I8.
Referring to the modified form shown in Figure 6, the construction and operation is substantially the same as in the form shown in Figure 1 with the exception that the entire neck is made from sheet metal integral with the annular iiange I6, thereby providing sheet metal threads IIn for the cap and the device is provided with a bend 23 which receives the marginal edge of the opening in the receptacle 24. The receptacle 24 may be a tin can or a collapsible tube if so desired, and applicant does not limit himself in this particular.
From the above it will be seen that a cap is provided for a receptacle neck, which will have the maximum range of movement, and one wherein when the cap is screwed to closed position the valve structure will be flexed for forming a leak proof structure incident, particularly, to the diaphragm 29 being forced into close engagement with the washer I8, the seating of the edge 2l in the curved seat 22 and the seating of the valve stem 25 in the seat 3. The seating of these parts is made possible by the flexible construction of the device.
The invention having been set forth what is claimed as new and useful is:
1. The combination with a receptacle neck, a valve cap threaded on said neck and having a valve seat axially disposed therein and a concentric valve seat surrounding the valve seat axially disposed, the concentric valve seat being upwardly and inwardly tapered, of a valve carried by the neck axially thereof, an annular valve carried by the neck and surrounding the first mentioned valve, said valves being stamped from a single piece of material and being hollow and in the path of the corresponding valve seat in the cap, said annular valve being V-shaped in transverse cross section and comprising an outer flange and an inner flange, said inner flange inclining downwardly and inwardly, a perforated disc carried by the downwardly and inwardly inclined flange, means carried by the neck and engaging the downwardly and inwardly extending flange and hunting the downward movement thereof and insuring a flexing thereof when the annular Valve is seated in the annular set of the cap when the cap is screwed tight, to closed position.
2. A device as set forth in claim 1 including a washer interposed between the downwardly and inwardly extending flange and the neck of the bottle.
