Abstract: This invention relates to a cylindrical holder member for a bi-directional bulged rupture disc. The support body of the holder has a rim that supports the rupture disc with the concave surface of the disc facing the holder. The support body is provided with a unitary one-piece, centrally creased cutting element that is of generally V-shaped configuration in plan view. The cutting element has a pair of elongated converging leg components with each leg component being connected to and supported by the interior wall surface of the holder body, with each leg component having an arcuate cutting edge. The cutting edges of the leg components merge at the crease in the cutting element to define a central cutting edge peak section. The cutting element is positioned in the holder with the cutting edge peak section extending beyond the rim of the support body into the concave area of the disc.

Abstract: A pressure relief valve for a container having a liner therein for holding food products includes a hollow body incorporated into a lid of the container and extends inwardly therefrom. A cutter member is mounted in an opening at an outer end of the body and has a knife extending inwardly through the valve body. A piston is slidably connected to the body and has an opening therein for receiving the knife and a compression spring is mounted around the knife and positioned between a top of the cutter and a bottom of the piston to bias the piston inwardly away from the wall. Pressure buildup in the liner causes the liner to expand and push the piston outwardly towards the lid to expose the knife which then punctures the liner and relieves the pressure therein and allows a product to be discharged from the container through the valve.

Abstract: A single-action discharge valve for discharging a vessel's contents. The valve has a valve body with a passage therethrough through which the contents are discharged, a frangible seal held within the valve body and sealing the passage while the seal is intact, and a solenoid including an armature moveable from a first to a second position. As the armature moves, pins or teeth impact and break the frangible seal. Magnets hold the armature in the first position until the solenoid is actuated. The armature is substantially exterior of the passage so that discharge is unimpeded. In one embodiment, the pins reciprocate radially when cammed by the armature and impact the sidewall of a frangible dome seal. In other embodiments, teeth on the armature, or pins in the armature's path, reciprocate parallel to the armature's movement and impact a frangible disk.

Abstract: An improved reverse rupture disc for use as a safety pressure relief device is provided. The disc is defined by an annular flat flange region, a concave-convex disc dome region and a transition region that joins the disc-shaped flat flange region to the concave-convex disc dome region. One or more deformations may be formed at or near the apex of the disc dome region for weakening the disc to the point that incidental damage to the disc will not weaken the disc any further, thereby ensuring that the disc will reverse at a certain pressure, and no lower. The disc may also formed with one or more irregular transition regions at the base of the disc and a partial circular groove in the transition region. The irregular transition region of the disc cooperates with a shear enhancing means such as a protrusion or notch formed in a support ring or disc holder disposed downstream of the disc to sever the disc dome from the annular flat flange region along the groove in the transition region.
