Abstract
A container washing and filling machine for washing and filling blow moulded containers 1 having an open-ended neck 2 includes only a single head 5 through which both washing and filling liquid is introduced into the container 1 through its open-ended neck 2. The container 1 is held in fluid-tight sealing engagement with the single head 5 by a clamping device 32 and the clamping device and single head 5 are movable together with a container 1 being treated between a washing position in which the container 1 is inverted and a filling position in which the container 1 is erect. Preferably the machine also inlcudes a closure unit 21 to apply a closure to the open-ended neck 2 of a filled container 1.
Claims20
A container washing and filling machine for washing and filling blow moulded containers having an open-ended neck, including only a single head through which both washing and filling liquids are introduced into said container through its said open-ended neck, means to supply a washing liquid to said single head, means to supply filling liquid to said single head, a clamping device arranged to engage and hold said open-ended neck of said container in fluid-tight sealing engagement with said single head, and moving means to move said single head and said clamping device together with said container being treated between a washing position wherein said container is inverted and a filling position wherein said container is erect, said fluid-tight sealing engagement between said single head and said open-ended neck of said container being maintained during said movement.
The container washing and filling machine of claim 7, said fulcrum means include spring means spring biasing said fulcrum means, and wherein each of said claws is C-shaped with one end pivotally connected to said movable body and said other end being arranged to engage said collar on said neck of said container, said fulcrum means being pivotally connected to said claws at a corner of said C-shaped claws adjacent their pivotal connection with said body.
A container washing and filling machine for washing and filling blow moulded containers having an open-ended neck surrounded by a collar, said machine including:
- only a single head through which both washing and filling liquids are introduced into said container through its said open-ended neck;
- means to supply a washing liquid to said single head;
- means to supply filling liquid to said single head;
- a clamping device arranged to engage and hold said open-ended neck of said container in fluid-tight sealing engagement with said single head;
- and,
- moving means to move said single head and said clamping device together with said container being treated between a washing position wherein said container is inverted and a filling position wherein said container is erect, said fluid-tight sealing engagement between said single head and said open-ended neck of said container being maintained during said movement;
- said clamping device comprising a movable body;
- a fluid pressure operated ram, said fluid pressure operated ram acting between said body and said single head to move said body with respect to said head;
- at least two claws, said claws being pivotally connected to said movable body;
- and fulcrum means, said fulcrum means engaging said claws whereby downwards movement of said body caused by said ram carries said claws downwards and reaction from said fulcrum means closes said claws behind said collar on said neck of said container, further downwards movement of said body caused by said ram causing engagement of said claws with said collar and urging said container downwards to move said open ended neck of said container into fluid-tight sealing engagement with said single head.
