Abstract: A joint strip is used comprising a container strip in thermoplastic material and a cover strip having sterile sides facing one another and isolated from the outside in a sealed manner along their edges. The container and cover strips are separated each from the other at the entrance to a sterile enclosure, the cover strip passing along a path which overhangs that of the container strip and passes above stations for forming containers in the container strip, and for filling the containers. The cover strip is exposed, on the side of its sterile face, to a sterile atmosphere whose pressure is slightly in excess of that of the outside. The cover and container strips are moved respectively above and below a non-sterile area containing elements of the forming and filling stations. After the containers carried by the container strip have been filled, the cover and container strips are again joined in a sealed manner along their edges outside the sterile enclosure.

Abstract: Receptacle such as a bottle, beaker or the like made of thermoplastic material, wherein each opening for extraction is constituted by a curved or polygonal slot at least partially closed on itself and made in the end wall by partially melting the thermoplastic material of which said wall is composed, and at least the parts of the end wall surrounding said slot are hermetically fast with a covering foil or cap coated with a layer of adhesive opposite said end wall.
