Abstract
Abstract A liquid filling device wherein an arcuate carrier is provided with track means carrying an intermediate region of tubing having its opposite ends communicating respectively with a liquid source and outlet container, and a tubing guide is selectively positionable along the track means for determining the length of intermediate tubing region extending along the track means, whereby roller means is movable to displace a predetermined volume of liquid through the tubing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
Liquid packaging apparatus comprising support means, a tubing carrier on said support means, generally planar track means extending along said carrier, resilient flexible tubing having an intermediate region extending along and in the plane of said track means, the remainder of said tubing being out of said track means plane, tubing guide means for varying the length of said intermediate tubing region in said plane along said track means, one end of said tubing extending to fluid communication with a source of fluid to be packaged and the other end of said tubing extending to fluid communication with a packaging container, and roller means mounted for movement in the plane of and along said track means in rolling engagement with said intermediate region of tubing to displace a quantity of liquid to the container.
Claim 2
Dependent Claim
134 words
Liquid packaging apparatus comprising support means, a tubing carrier on said support means, generally planar track means extending along said carrier, resilient flexible tubing having an intermediate region extending along and in the plane of said track means, the remainder of said tubing being out of said track means plane, tubing guide means for varying the length of said intermediate tubing region in said plane along said track means, one end of said tubing extending to fluid communication with a source of fluid to be packaged and the other end of said tubing extending to fluid communication with a packaging container, and roller means mounted for movement in the plane of and along said track means in rolling engagement with said intermediate region of tubing to displace a quantity of liquid to the container.
Claim 3
Dependent Claim
50 words
Liquid packaging apparatus according to claim 1, said track means being generally arcuate and fixed relative to said support, said guide means being selectively positionable along said track means, and said roller means being mounted for movement along said arcuate track means independently of the position of said guide means.
Claim 4
Dependent Claim
45 words
Liquid packaging apparatus according to claim 2, said track means extending externally about the periphery of said carrier, said guide means defining a passageway communicating with said track for leading tubing out of the plane of said track at any selected position along the latter.
Claim 5
Dependent Claim
29 words
Liquid packaging apparatus according to claim 3, said roller means being mounted for eccentric rotation in said rolling engagement in the plane of said track generally externally tangential thereto.
Claim 6
Dependent Claim
49 words
Liquid packaging apparatus according to claim 1, said track means being of generally convex arcuate configuration, and said roller means comprising an arm swingable about the center of curvature of said arcuate configuration, and a roller carried by said arm at a radius greater than that of said curvature.
Claim 7
Dependent Claim
46 words
Liquid packaging apparatus according to claim 5, said tubing guide means comprising a guide arm pivoted about said center of curvature, and a tubing receiver on said guide arm slidably receiving said tubing and guiding the latter transversely of said track out of the track plane.
Claim 8
Dependent Claim
26 words
Liquid packaging apparatus according to claim 6, in combination with releasable securing means for securing said tubing receiver at any selected position of its arcuate movement.
Claim 9
Dependent Claim
50 words
Liquid packaging apparatus according to claim 7, said tubing receiver comprising a pair of guide elements spaced along said track and defining a passageway therebetween opening transversely of said track for slidably receiving a portion of said tubing extending transversely of said track upon pivotal movement of said guide arm.
