Low pressure venting panel

A low pressure venting panel comprising:

• (a) a substantially flat, rectangular rupture body having a center and a peripheral margin;
• (1) said body having four elongate slits therein;
• each of said slits being divided into a plurality of segments by bridges connecting said rupture body on opposite sides of a respective slit;
• said slits being located substantially near diagonals of said body;
• said slits terminating at one end substantially near said peripheral margin and terminating at an opposite end closely spaced from said center of said body;
• (b) a sealing membrane bonded to said rupture body, said sealing membrane being bonded to said rupture body near and on both sides of each of said slits;
• said sealing membrane being of a semi-elastic material and being substantially resistant to expansion in the area of said slits.

A low pressure venting panel comprising:

• (a) a substantially flat, rectangular rupture body having a center, a central portion, a peripheral margin and a central axis bisecting said rupture body and extending parallel along a side of said retangular rupture body;
• (1) said rectangular rupture body having dimensions approximately proprotional to 40 inches by 24 inches;
• (2) said central portion having dimensions approximately proportional to 30 inches by 17 inches and having a center identical with said center of said rectangular rupture body;
• (3) said central portion having two apertures spaced approximately 0.75 inches apart in proportion to the dimensions in paragraph (a)(1) and being symmetrically disposed about said center of said panel;
• said apertures being positioned on said central axis;
• (4) said central portion having four slits extending between near said peripheral margin and an area closely spaced from said apertures;
• each of said slits being located substantially along diagonals of said central portion and having bores on both ends;
• (b) a sealing membrane bonded to said rupture body;
• said sealing membrane being bonded to said rupture body at least near both sides of said slits and substantially resistant to expansion in the area of said slits.

A venting panel comprising:

• (a) a rupture body with at least one rupture directing slit therein;
• (b) a sealing member adjacent said rupture body;
• (c) said sealing member being bonded to said rupture body at least in close proximity to each side of said slit;
• and
• (d) a protective strip operably positioned between said body and said sealing membrane;
• said strip being elongate and substantially wider than said slit;
• said strip being operably positioned adjacent said slit to help prevent said sealing member from creeping through said slit prior to rupture of said vent panel.
