Abstract
Pressure relief channels are provided at the neck of beverage bottles of the type having roll-on (twist-off) closures to release gas pressure within the closure promptly as the closure is turned to remove it and before missiling of the closure can occur.
Claims27
An improved container of the type having a neck provided externally with circumferential beads including threads for receiving a threaded cap to contain pressurized fluids, the improvement comprising means including at least one venting channel extending transversely into at least one of said beads for providing release of fluid pressure from beneath said cap sufficient to prevent missiling of the cap when the cap is initially turned to remove it from said container, the channel traversing at least one of the turns of the threads, the depth of the channel perpendicular to the surface of the container being greater than the thread depth.
In combination with a bottle of the type having a neck provided externally with circumferential beads including threads and a rolled-on threaded cap arranged to seal against the mouth of the bottle to contain pressurized beverages and the like, means including a venting channel extending transversely into at least one of said beads for releasing fluid pressure from beneath said cap sufficiently to prevent missiling of said cap when said cap is turned to remove it from said bottle, the channel traversing at least one of the turns of said threads, the depth of said channel perpendicular to the surface of said container being greater than the thread depth.
An improved bottle of the type having a neck provided externally with circumferential beads including about 11/4 turns of threads for receiving a roll-on threaded cap to contain pressurized beverages and the like, the improvement comprising at least one venting channel extending transversely into at least one of said beads and having a width of about one-sixteenth inch, the channel also extending through at least one turn of the threads, the depth of said channel perpendicular to the surface of said container being greater than the thread depth.
