Reduced pressure assembly and method

The present disclosure relates generally to an exhaust system (20) that includes a wall (26, 28) of a lid or container (22) defining a central longitudinal axis (50) and a straight section (52) measured from the longitudinal axis (50) to an outermost surface of the lid or container (22), and a decompression feature (24) disposed along the lid or container (22). The reduced pressure feature (24) includes a thinned region (58) of the lid or container (22) that defines a minimum thickness that is less than 40% of the maximum thickness of each lid or container (22). The relief feature (24) extends at least 180 degrees about the longitudinal axis (50), and the relief feature (24) is located at a distance from the longitudinal axis more than 80% of the straight section (52). 本公开总体涉及一种排气系统(20)，该排气系统包括盖子或容器(22)的壁(26，28)，该盖子或容器(22)限定了中心纵轴线(50)，和从纵轴线(50)到盖子或容器(22)的最外表面测量的直线区段(52)，以及沿盖子或容器(22)设置的减压特征(24)。减压特征(24)包括盖子或容器(22)的减薄区域(58)，该减薄区域限定了最小厚度，该最小厚度小于各盖子或容器(22)最大厚度的40％。减压特征(24)围绕纵轴线(50)延伸至少180度，且减压特征(24)位于与纵轴线的距离超过直线区
