A molded plastic container (10, 110, 210) having an open neck portion (12, 112, 212), the container being adapted to have a collapsible bladder (B) inserted therein. The bladder has a metallic ferrule (F) at an open end thereof, and the ferrule is adapted to be supported at a location adjacent a rim (14, 114, 214) of the neck portion. To provide for venting from the container during the filling of the bladder, and later during the dispensing of product therefrom, the rim is provided with a plurality of spaced apart upstanding bosses (16, 116, 216) which define slots (18, 118, 218) between adjacent ends of adjacent bosses. The ferrule, thus, rests on the bosses, and air can vent beneath the ferrule and the container through the slots. The container can also vent during dispensing, even with a closure C affixed thereto, by providing a radial bead (22, 122, 222) in the container with a plurality of longitudinally extending slots (24, 124, 224) in the exterior thereof. Further, venting of the container, in the region between a juncture of the neck portion and a shoulder portion (26, 126, 226) and the portion of the bladder surrounded by such region can be accomplished by providing a circumferentially spaced apart series of radially outwardly projecting dimples (28, 128) and, if need be, by providing a circumferentially spaced apart plurality of longitudinally extending recesses (130, 230) on the inside of the open neck portion (112, 212).
