Abstract: A seal construction for a container door which has a first resiliently deformable part of predetermined generally channel sectioned shape for application to the edge portions of a container door to preclude the passage of moisture to the door edges, and a second part connected to the first part and having at least one resiliently deformable sealing arm for sealing engagement with a portion of the container around the door opening. In the preferred arrangement, the first and second parts are separate and a third part is provided to connect the two parts together, and in one arrangement the tips of the arms of the channel shaped part are of a softer material than the remainder of the seal. In a second construction, the tip of one of said arms is joined to the remainder of the arm by a softer portion and in this second construction the whole seal may be a one-piece extrusion.
