Abstract
A method for producing containers (10) filled with liquid, more particularly drinks containers, wherein plastic preforms are shaped into plastic containers (10) by means of a shaping device (2), these plastic containers are transported to a filling device (4) and are filled with a liquid by means of this filling device, wherein, on their transport path between the shaping device (2) and the filling device (4) the containers (10) are cooled, at least partly, by being charged with a liquid medium. According to the invention the containers are transported, at least during filling, within a clean room (20) which is delimited from an environment by means of a sealing device (62).
Claims18
A method of producing containers (10) filled with liquid, wherein plastics material pre-forms are shaped to form plastics material containers (10) by a shaping device (2), these plastics material containers are conveyed to a filling device (4) and are filled with a liquid by the filling device, wherein the containers (10) are cooled on their conveying path between the shaping device (2) and the filling device (4) at least in sections by being acted upon with a liquid medium, wherein the containers are conveyed at least during the filling inside a clean room (20) which is bounded off from an environment by a sealing device (62), and wherein at least one clean room (12, 20) is sealed off by the use of a sterile liquid conveyed in a continuous duct (62a, 62b, 72a, 72b), and the liquid from this duct (62a, 62b, 72a, 72b) is also used in order to cool the containers.
An apparatus (1) for the production of containers (10) filled with liquid, with a shaping device (2) which shapes plastics material pre-forms into plastics material containers (10) by acting upon them with a gaseous medium, with a filling device (4) which is arranged in a conveying direction of the plastics material pre-forms downstream with respect to the shaping device (2) and which fills the plastics material containers (10) with a liquid, and with a cooling device (6) which is arranged between the shaping device (2) and the filling device (4) and which acts upon the plastics material containers (10) with a liquid medium at least in sections in order to cool them, wherein at least the filling device (4) has a clean room (20), inside which the containers are capable of being conveyed during the filling thereof and which is bounded off from an environment by at least one sealing device (60), and wherein at least one sealing device (60, 70) has a continuous duct (62a, 62b, 72a, 72b) capable of being filled with a liquid, and a line (66) is provided by way of which liquid is capable of being supplied from this duct (62a, 62b, 72a, 72b) to the container (10) for the cooling thereof.
