<p>The container (10) has a pressure body (20) for receiving filling material and exerting pressure on the filling material. The pressure body comprises a material layer that is made of polyurethane elastomer, where hardness of the polyurethane elastomer is within a range of 60-70 shores A. The polyurethane elastomer is formed by polyaddition of diisocyanates, polyether or polyester polyol, where density of the elastomer is within a range of 1.1 and 1.2 gram per cubic cm. A predominant part of a housing (12) is made of plastic material, pasteboard or sheet metal.</p> |
