The container is made form all kinds of material which can be thermo-welded. The cover (2) is cut out and thermo-formed at the same time as the container on the same machine. The cover is positioned on the container boat either manually or automatically and fixed on one of its sides (5) by a partial weld serving as a hinge (6). The assembled cover and container are covered by a sealing film giving an inviolability to the assembly. |
