摘要:
A process for preparation of metal vessels by lap-bonding circumferential open end portions (3,4) of preformed outer and inner seamless metal cup members (2,1) to each other with an adhesive layer (11) interposed between the open end portions (3,4) of both the members (2,1), by heating the fitted portions (Sa) of both the outer and inner members (2,1) so as to melt the adhesive and by subsequent controlled cooling the fitted portions (5a) so that the temperatures of the fitted portions of both the outer and inner members are substantially equal to each other just before solidification of the adhesive.

Disclosed is an aseptic filling valve comprising a valve seat (2) arranged within a tubular member (1), an interior moving member (4) arranged in the tubular member and having a valve body (3), an exterior moving member (8) arranged outside the tubular member (1) and magnetically coupled with the interior moving member (4), a wall member (12) including the exterior moving member (8) therein and a pressure chamber (15) defined by said wall member (12), tubular member (1) and exterior moving member (8) wherein the exterior moving member (8) is moved by applying a fluid pressure to the interior of the pressure chamber (15) and the interior moving member (4) is moved in follow-up with the movement of the exterior moving member (8) to effect the operation of opening and closing the valve.

Disclosed is a metal vessel comprising upper and lower members, each of which consists of a seamless molded metal cup having a protecting resin cover layer, the open end portions of the upper and lower members being lap-bonded to each other through an adhesive to form a circumferential side seam, said metal vessel being characterized in that the open end portion defining the inner side of the circumferential side seam has a layer of a thermoplastic resin adhesive tape heat-bonded along the entire circumference of said end portion while wrapping the end edge and adjoining inner and outer side faces therein, a layer located on the outer side face of the adhesive tape is extended along the lap-bonded portion, and the adhesive layer present in the lap-bonded portion satisfies the following requirement: wherein S 1 stands for the sectional area (mm 2 ) of the adhesive layer present in the lap-bonded portion, eo stands for the width (mm) of the lap-bonded portion, and to stands for the thickness (mm) of the adhesive tape present on the inner side of the inner open end portion.

Disclosed is an aseptic filling machine comprising a filling zone (15) defined by walls, a vessel-supporting mechanism arranged in the filling zone (15), a content-filling nozzle (8, 8a) arranged in the filling zone, a pipe passage (5, 5a) for supplying the content to the filling nozzle, an air blow-out opening (9, 9a) for producing a positive pressure locally in the filling zone, a fluid passage-forming connecting member (20, 20a) for detachably connecting the filling nozzle (8, 8a) and the air blow-out opening (9, 9a), and a changeover mechanism (22, 22a) for connecting the air blow-out opening (9, 9a) alternatively to an aseptic air supply source and a tank for recovering a cleaning liquid or a sterilizing fluid, wherein the air blow-out opening (9, 9a) forms a part of a pipe passage for recovering the cleaning liquid or sterilizing fluid. In this filling machine, the filling zone (15) is defined and localized by walls (11, 12, 13, 14), and a positive pressure can be produced and maintained very easily in the filling zone (15). Furthermore, since the aseptic air supply pipe passage is utilized as a part of the cleaning liquid or sterilizing fluid recovery pipe passage, the aseptic air supply pipe passage and the content filling pipe passage or content feed passage can be simultaneously cleaned or sterilized by one mechanism and an excellent contamination-preventing effect can be attained by a simple structure and mechanism.
