<p>The invention relates to an apparatus for dispensing a product under pressure, having a flexible bag with an outlet opening, wherein elastic means are arranged around the bag and subject the latter to a pressure in the direction of its centre. In order to provide an apparatus which is intended for dispensing a product under pressure, and allows for the apparatus to be emptied at least substantially in its entirety at a uniform dispensing rate, it is proposed, within the context of the invention, that the elastic means comprise at least one elastic band arranged at least in certain sub-regions around the bag. It has surprisingly been found, within the context of the invention, that an elastic band wound around the flexible bag makes it possible for the bag to be subjected to pressure loading corresponding substantially to the pressure loading which takes place in a pressure vessel. It is possible here both to achieve a uniform dispensing rate from the first application to the last application and for the bag contents to be emptied virtually in their entirety.</p> |
