Abstract
A pressure relief blow-out plug includes a body including an inboard end and an outboard end, and an inboard flange extending radially outwardly from the inboard end of the body. A package includes a container including a wall having interior and exterior surfaces, and a pressure relief passage extending along a longitudinal passage axis and having a circumferential passage surface extending through the wall between the interior and exterior surfaces, wherein the pressure relief blow-out plug is carried in the pressure relief passage.
Claims20
A package, comprising:
- a container including a wall having an interior surface and an exterior surface, and a pressure relief passage extending along a longitudinal passage axis and having a circumferential passage surface extending through the wall between the interior and exterior surfaces;
- and
- a pressure relief blow-out plug carried in the pressure relief passage of the container, the pressure relief blow-out plug comprising:
- a body including an inboard end and an outboard end;
- a first inboard flange extending radially outwardly from the inboard end of the body and having an outboard sealing surface that is circumferentially continuous;
- a stem extending longitudinally away from the first inboard flange;
- and
- a second inboard flange extending radially away from the stem and longitudinally spaced apart from the first inboard flange, and having an outboard facing retention portion that is circumferentially interrupted to include circumferentially spaced bosses and vent gaps between the bosses;
- wherein the first inboard flange of the pressure relief blow-out plug is in contact with the interior surface of the wall of the container, and wherein upon excess pressure within the container, the pressure relief blow-out plug is displaced such that the first inboard flange of the pressure relief blow-out plug is pushed through the pressure relief passage and the second inboard flange of the pressure relief blow-out plug contacts the interior surface of the wall of the container to retain the pressure relief blow-out plug to the container, and such that gas inside the container is permitted to escape between the second inboard flange of the pressure relief blow-out plug and the wall of the container via the vent gaps.

- and
- a pressure relief blow-out plug carried in the pressure relief passage of the container, the pressure relief blow-out plug comprising:
- a body including an inboard end and an outboard end;
- an outboard head extending radially outwardly from the outboard end of the body;
- and
- an inboard flange extending radially outwardly from the inboard end of the body and including an outboard surface, and an inboard surface having a deformation weakening to facilitate deformation of the inboard flange;
- wherein the outboard head is in contact with the exterior surface of the wall of the container and the inboard flange is in contact with the interior surface of the wall of the container, and wherein upon excess pressure within the container, the pressure relief blow-out plug is displaced through and out of the pressure relief passage.
