Abstract: Packaged formulation comprising a compound liable to exothermic decomposition and optionally one or more organic diluents, said formulation being packaged in a container with a volume of at least 250 liter provided with a vent to release gases and made from a thermoplastic material having a Vicat B softening temperature not higher than (a) the run-away temperature of the compound liable to exothermic decomposition if the formulation does not contain any diluent, or (b) the boiling temperature of at least 50 wt % of the total weight of diluent if the formulation does contain organic diluent.

Abstract: Pressure release container, e.g. for peroxide materials, with a spout opening (2), a neck (3) along the periphery of the spout opening, and a venting cover (5). The venting cover comprises a body plate (6) to cover the spout opening, the body plate having a vent opening (7) and having a flange (9) with fastening means, e.g. a screw thread (4), to cooperate with corresponding fastening means on the outer face of the neck. The vent opening is covered by a gas permeable sheet (11) fixed between the fastening means of the neck and the flange. The vent opening can be provided with a pop-off cap (8).
