Patent number: 9499330Abstract: A pressure relief device for venting an internally pressurized container and an aerosol can having a can bottom containing this pressure relief device. The pressure release device includes a coined pressure vent within a domed can bottom. The pressure vent is characterized by a venting pressure greater than about 500 psig. In addition, the can bottom resists eversion and/or failure along the mechanical attachment to the container body at all pressures between the venting pressure and the longitudinal rupture pressure in the container body.Type: GrantFiled: June 23, 2013Date of Patent: November 22, 2016Assignee: ILLINOIS TOOL WORKS INCInventors: Richard A. Henry, Mark A. Ferreira, Yurij F. Wowczuk

Patent number: 8967411Abstract: A pressure relief device of domed construction for venting an internally pressurized container. The pressure release device includes a coined pressure vent and is characterized by a relatively high venting pressure in combination with a failure pressure in the absence of venting which is higher than the intended venting pressure. The pressure relief device includes a sloped sidewall having an outer annular segment and a sloped annular intermediate segment. The sloped annular intermediate segment has a width dimension greater than the width dimension of the outer annular segment. A circular central plateau defines a flat dome top. The circular central plateau has a center point with an arc shaped coin line extending about an arc with the apex of the arc positioned at the center point of the circular central plateau.Type: GrantFiled: June 3, 2011Date of Patent: March 3, 2015Assignee: Illinois Tool Works Inc.Inventors: Mark A. Ferreira, Yurij F. Wowczuk, Richard A. Henry

Patent number: 7621166Abstract: A pressure relief device for venting an internally pressurized container such as an aerosol can has three sections, a concave annular outer area, a circular central area and an annular intermediate area connecting the concave annular area to the circular area. The three sections all have the same thickness. The central area has a center point and an arc shaped score line extending through 132° to 138°, preferably 135°, about an arc center. The arc center is offset from the center point of the circular area by a distance of from about 0.290 inches. The score line has a depth of from 0.010 to 0.012 inches and is trapezoidal in transverse cross section. The intermediate area meets the circular area at an angle greater than 90° and the intermediate area meets the concave annular outer area at an angle greater than 90°.Type: GrantFiled: April 4, 2007Date of Patent: November 24, 2009Assignee: Illinois Tool Works Inc.Inventors: Mark A. Ferreira, Yurij F. Wowczuk, Richard A. Henry, Richard H. Raborn
