The present invention relates to improvements in bottle closures and more particularly to that type embodying means permitting the escape of gas which is formed by certain bottled liquids 5 and which very frequently build up suil'lclent pressure to break the container or closure.
An object of the invention is the provision of a novel closure and diaphragm, the latter functioning asa sealing gasket which will effectively prevent the admission of air, but will permit the escape of gas or the like in the reduction of internal pressures.
A further object of the invention is the provision of a venting feature which may be embodied in both molded and sheet metal closures with equal facility.
Other objects will be in part apparent and In part pointed out hereinafter.
In the drawing:
Fig. 1 is a fragmentary sectional view showing my invention embodied in a molded closure:
Fig. 2 is a detail sectional view of the closure;
Fig. 3 is a sectional view taken substantially along the line 3-3 of Fig. 1t
Fig. 4- is a plan view of the diaphragm or sealing disk;
Fig. 5 is a fragmentary sectional view illustrating the embodiment of my invention in a sheet metal closure; and
Fig. 6 is a detail sectional view taken substantially along the line S--B of Fig. 5.
In Figs. l. to 4, both inclusive, illustrating one form of the present invention, the closure C is threaded upon the reduced neck Il) of a bottle 35 il, said neck terminating in an annular sealing surface I2 with which a diaphragm I3, or sealing gasket formed of rubber or rubber composition, is held firmly engaged by said closure. A slit ill constituting a vent opening is provided in the diaphragm at a point substantially midway between its periphery and center.
The closure C includes a circular top I5 or button and a depending skirt IB or attaching flange which is formed with internal screw threads I1. the latter adapted for engagement with external threads I8 on the neck I0.
A centrally disposed vent opening I9 is formed in the top I5 or button, the lower or inner end of said opening being closed by contact with the diaphragm I3 or sealing disk. A channel 20 or groove is formed in the lower or inner face of the top I 5 concentrically with respect to the vent opening I9 and has communication with the latter by way of a radial groove 2l or passageway.
With such a structure as that just described, it is apparent that irrespective of the position of the diaphragm immediately following normal application of the closure C, the slit Hl or vent in the diaphragm will be in register with the annular channel 20 at one point or another,
(Cl. 21S-56) with the result that venting of excess gas pressure is always possible. It is obvious that the slit is normally closed but will open momentarily under excess internal pressure.
In Figs. 5 and 6 there is illustrated another form of the present invention,Y differing from that shown in Figs. 1 to 4 only to the extent necessary to embodying the invention in a sheet metal closure.
The closure C is threaded upon the bottle neck I and includes the circular top I5 or button and a depending attaching flange I6 or skirt which is threaded upon the bottle neck. The diaphragm I3, or sealing disk, is of the same construction as that described above.
The circular top I of the closure is provided with an upstanding hollow annular bead 22 which creates an annular channel 23 or groove in the lower side of and concentric with said top. A radial passageway 24. or groove, opens at one end 25 into the annular channel 23 and at its other end in a port 26 through which it communicates with the outside air substantially at the center or axis of the closure. It will be observed that the upper wall of the radial passageway 24 is somewhat below the plane of the top surface of the bead 22 with the result that the latter aiords a certain degree of protection against the possibility of collapsing the wall of the channel 2l and closing the port 26.
Modiilcations may be resorted to within the spirit and scope of the appended claims.
i. A closure including a top having a depending annular attaching flange, said top having a continuous circular annular groove formed in its lower side, a centrally disposed venting opening extending through the top and a radial groove connecting the annular groove and opening, and a circular resilient sealing disk disposed in the top, said disk being provided with an eccentrically disposed normally closed venting slit in register with the annular groove.
