Abstract: The present invention relates to a disposable container comprising a side wall, top and bottom, wherein the side wall and the bottom comprise a flexible material, wherein the side wall, top and bottom are joined together to define the container with an interior compartment for keeping a fluid inside the container. The bottom of the container comprises at least one portion of rigid or semi-rigid material comprising a folding means that enables folding of the bottom. Thus an easy way of folding the bottom of the container is provided.

Abstract: The present invention relates to a disposable container (100) comprising a side wall (2, 32), top (4) and bottom (6), wherein the side wall (2; 32) and the bottom (6) comprise a flexible material, wherein the side wall (2; 32), top (4) and bottom (6) are joined together to define the container (100) with an interior compartment (10) for keeping a fluid inside the container (100). The bottom (6) of the container (100) comprises at least one portion of rigid or semi-rigid material comprising a folding means (124; 224; 324; 324?) that enables folding of the bottom (6). Thus an easy way of folding the bottom of the container is provided.

Abstract: A container comprising a first material and a second material, the first material being a flexible material and the second material being a rigid or semi-rigid material and at least partially defining an interior compartment for keeping a fluid inside the container characterized in that the flexible material and/or the semi-rigid or rigid material have thermoplastic properties and wherein the flexible material and the semi-rigid or rigid material are joined together by a seal or joint which comprises a heat seal and an adhesive seal.

Abstract: The present invention relates to improvements of bioreactor bags for cell cultivation. The invention provides an inflatable bioreactor bag for cell cultivation comprised of a top and a bottom sheet of polymer material that are joined along their edges to form a sealed bag, wherein two opposing edges are formed as clamping edges to allow clamping of the bioreactor bag to a rocker type bioreactor, wherein the top sheet is at least 5% longer than the bottom sheet between the clamping edges. The bioreactor bags provided by the invention avoid formation of undesired wrinkles or creases which otherwise may lead to fatigue of the plastic and eventually fracture.

Abstract: The present invention relates to improved single-use bioreactors comprising disposable plastic bags for cell cultivation. The invention provides an inflatable bioreactor bag for cell cultivation comprised of a top and a bottom sheet of polymer material that are joined along their edges to form a sealed bag, wherein two opposing edges are formed as clamping edges to allow clamping of the bioreactor bag to a rocker type bioreactor, and wherein the bioreactor bag is provided with a wrinkle preventing structure at each end of the clamping edges. The bag avoids formation of undesired wrinkles or creases which otherwise lead to fatigue of the plastic and eventually fracture.
