Abstract
Abstract A chain of imbricated bags connected and supported by a carrier removably secured to the closed end of each of the bags is used for individually dispensing the leading bag when the carrier is moved in a direction which advances the sealed end of the bag ahead of the open end. A method and apparatus for dispensing such bags are also included.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A method for dispensing flexible bags from a chain of imbricated bags, said bags being removably secured to a carrier, comprising the steps of: moving said carrier in a first direction to dispose the leading bag of said chain of imbricated bags in a dispensing position, said bags having a closed end and an open end, said open and closed ends being connected by generally planar bag sides and substantially linear bag edges when said bags are in a flattened state, one of said sides adjacent said closed end being secured to said carrier, said carrier running substantially in the same direction as said edges, and said closed end preceding said open end in said first direction; removing said lead bag from said chain along a path substantially oppositely opposed to said first direction; and advancing said carrier along said first direction to dispose a second bag in said dispensing position.
Claim 2
Independent Claim
151 words
A method for dispensing flexible bags from a chain of imbricated bags, said bags being removably secured to a carrier, comprising the steps of: moving said carrier in a first direction to dispose the leading bag of said chain of imbricated bags in a dispensing position, said bags having a closed end and an open end, said open and closed ends being connected by generally planar bag sides and substantially linear bag edges when said bags are in a flattened state, one of said sides adjacent said closed end being secured to said carrier, said carrier running substantially in the same direction as said edges, and said closed end preceding said open end in said first direction; removing said lead bag from said chain along a path substantially oppositely opposed to said first direction; and advancing said carrier along said first direction to dispose a second bag in said dispensing position.
Claim 3
Dependent Claim
68 words
The method according to claim 1 comprising, prior to said step of moving, the further step of advancing said carrier in a direction substantially oppositely opposed to said first direction to a point at which said direction of advance is changed to said first direction by pivoting said carrier about a point, said open end of said bag in said dispensing position being substantially coincidental with said point.
Claim 4
Dependent Claim
28 words
The method according to claim 1 wherein said carrier comprises at least two parallel strands of tape and said bags are secured to said tape by an adhesive.
Claim 5
Dependent Claim
59 words
The method according to claim 2, including the further step of: detecting the position of a bag in the dispensing position and discontinuing said advance until said bag is removed from said dispensing position; detecting the removal of said bag from said dispensing position; and further advancing said carrier until the next succeeding bag is in said dispensing position.
Claim 6
Independent Claim
121 words
An apparatus for dispensing flexible bags said flexible bags being attached in an imbricated fashion to a carrier, said bags having an open end and a closed end, said closed end being attached to said carrier, said apparatus comprising; p1 a dispensing surface; means for advancing said carrier in a first direction across said dispensing surface; means for detecting the presence or absence of a container in a dispensing position on said dispensing surface; control means for deactivating said means for advancing when said dispensing position is occupied and for activating advancing means when said dispensing position is vacant; and a roller to pinch the open end of the container in the dispensing position against an edge of said dispensing surface.
Claim 7
Independent Claim
121 words
An apparatus for dispensing flexible bags said flexible bags being attached in an imbricated fashion to a carrier, said bags having an open end and a closed end, said closed end being attached to said carrier, said apparatus comprising; p1 a dispensing surface; means for advancing said carrier in a first direction across said dispensing surface; means for detecting the presence or absence of a container in a dispensing position on said dispensing surface; control means for deactivating said means for advancing when said dispensing position is occupied and for activating advancing means when said dispensing position is vacant; and a roller to pinch the open end of the container in the dispensing position against an edge of said dispensing surface.
