Abstract: An insert for holding open and supporting in a generally upright position a trash bag not capable of self-support is disclosed. The insert is a generally rectangular member which is rollable on itself. The rectangular member has resiliency characteristics such that it tends to unroll when rolled upon itself. The member is sized such that when it is rolled upon itself and inserted within the trash bag it unrolls until restrained by the bag and therefore the bag is held open and supported in a generally upright position.
