Abstract
Abstract A dispenser for plastic bags comprises a container having a dispensing opening through which bags can be withdrawn seriatim from the container. The bags are stacked within the container and each lead bag has a trailing end connected by a line of weakened resistance to the leading end of the trailing bag so that when a lead bag is pulled through the opening, cooperating shoulders on the trailing bag at the ends of reclosable fastener assembly brake the container at the opening and cause the bags to separate at the weakened line. The separated trailing bag is disposed at the opening for subsequent convenient withdrawal. The bags may be stacked by top end-connected pairs within the container. Pressure sensitive adhesive retains the container on a support against displacement when pulling bags from the container. The container may carry a replaceable closure flap for the dispensing opening.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
246 words
A dispenser for reclosable plastic bags, comprising: a container having a dispensing opening through which bags can be withdrawn seriatim from said container; brake means on said container at said dispensing opening; a pack of plastic bags within said container and each bag having a leading end portion and a trailing end portion; means connecting said bags at least two-by-two with the trailing end portion of a lead bag attached to the leading end portion of a trailing bag along a line of weakened resistance; a reclosable fastener assembly extending from side-to-side on the leading end portion of the trailing bag adjacent to said connecting means; said fastener assembly and said brake means cooperating for effecting automatic separation at said line of weakened resistance of the lead bag from the trailing bag when the lead bag is pulled from the container through said opening and pulls said leading end portion of the trailing bag toward and into engagement of the reclosable fastener on said leading end portion against said brake means; and said pack of bags comprising pairs of bags stacked within the container, said bags having top ends comprising the trailing end portion of the lead bag and the leading end portion of the trailing bag, the top ends of both of the bags in each pair having separable fastener assemblies on the top end of each bag will pull flanges projecting from the fastener assemblies and connected end-to-end at said line of weakened resistance.
Claim 2
Dependent Claim
246 words
A dispenser for reclosable plastic bags, comprising: a container having a dispensing opening through which bags can be withdrawn seriatim from said container; brake means on said container at said dispensing opening; a pack of plastic bags within said container and each bag having a leading end portion and a trailing end portion; means connecting said bags at least two-by-two with the trailing end portion of a lead bag attached to the leading end portion of a trailing bag along a line of weakened resistance; a reclosable fastener assembly extending from side-to-side on the leading end portion of the trailing bag adjacent to said connecting means; said fastener assembly and said brake means cooperating for effecting automatic separation at said line of weakened resistance of the lead bag from the trailing bag when the lead bag is pulled from the container through said opening and pulls said leading end portion of the trailing bag toward and into engagement of the reclosable fastener on said leading end portion against said brake means; and said pack of bags comprising pairs of bags stacked within the container, said bags having top ends comprising the trailing end portion of the lead bag and the leading end portion of the trailing bag, the top ends of both of the bags in each pair having separable fastener assemblies on the top end of each bag will pull flanges projecting from the fastener assemblies and connected end-to-end at said line of weakened resistance.
Claim 3
Dependent Claim
87 words
A dispenser according to claim 1, wherein although said trailing bag reclosable fastener assembly has a beam strength rigidity which resists deformation of the fastener assembly during pulling of the lead bag with force sufficient to effect said separation, said fastener assembly is of sufficient resilient deflectability to permit snaking out of said opening past said brake means in response to direct pull on the leading end pull flange of said trailing bag for pulling the trailing bag past said brake means and out of the container.
Claim 4
Dependent Claim
42 words
A dispenser according to claim 1, wherein said container has brake means shoulders at opposite sides of said opening which are spaced apart about 25% less than the width of said pull flanges for crampingly engaging the sides of said pull flanges.
Claim 5
Dependent Claim
75 words
A dispenser according to claim 1, wherein said container is of rectangular shape and elongated between a front wall and a rear wall, said front wall having said opening and which is narrower than said pack of bags, said trailing bag having shoulder means on the ends of said trailing bag reclosable fastener assembly, and said brake means cooperating with said shoulder means for effecting stopping of said trailing bag to facilitate said automatic separation.
Claim 6
Dependent Claim
27 words
A dispenser according to claim 4, wherein said container has a top wall, and said opening has an extension from said front wall into said top wall.
Claim 7
Dependent Claim
22 words
A dispenser according to claim 5, wherein a closure flap on the container is replaceably related to said opening including said extension.
Claim 8
Dependent Claim
81 words
A dispenser according to claim 1, said pull flange of said trailing bag being cramped within said opening when pulled through the opening by pull on said lead bag, and said opening having said edges which frictionally retain such pull flange against reversion after separation of said lead bag from said trailing bag so that after the separation such pull flange will serve as a handle which may be grasped for pulling the trailing bag from the container through said opening.
Claim 9
Dependent Claim
31 words
A dispenser according to claim 1, wherein opposite ends of the reclosable fastener assembly of the trailing bags have shoulders which are drawn toward said brake means when effecting said separation.
Claim 10
Dependent Claim
50 words
A dispenser according to claim 1, wherein said container has a wall having the dispensing opening and connected angularly to another wall, and the dispensing opening has continuously connected parts thereof in said walls with both of said parts of the opening being shorter than the width of the opening.
