<p>An ostomy collecting bag is provided. The collecting bag has a continuous wall with a curvature instead of sealed edges. The collecting bag is truly three- dimensional. The collecting bag may be obtained by injection blow -moulding or extrusion blow -moulding. Methods of producing an ostomy collecting bags by either injection blow- moulding or extrusion blow- moulding is also provided. In injection blow- moulding, a pre -form is injection moulded and subsequently the pre form is blow- moulded into an ostomy collecting bag. In extrusion blow- moulding , a tube is extruded and subsequently blow- moulded into an ostomy collecting bag. The ostomy collecting bag can thus be made without seals at the edges, which provides a more flexible collecting bag with a larger interior volume.</p> |
