A dispenser package comprising in combination a dispensing container having therein a collection of inter-connected severable sheet material, said container having at least one unitary multi-functional dispensing orifice, said orifice having an intercommunicating first part and second part, the first part is in one wall of the container and the second part is in another contiguous wall of the container, said first part having a periphery which defines a comparatively broad area said first part periphery also defines a plurality of comparatively narrow areas, said first part periphery narrowing and merging with said second part, said second part also having a periphery which defines an area narrower than the region of merging and being remote from all other areas.
Claim 3
Dependent Claim
76 words
The dispenser of claim 1 wherein said comparatively broad area is sufficiently large to permit at least comparatively free dispensing of said sheet material therethrough and said comparatively narrow areas are of a dimension so that when a dispensed sheet member is moved laterially into a selected one from said broad area, substantial gathering of said sheet material will be affected so as to at least contribute to dispensing resistance and facilitate severance of said material.
Claim 4
Dependent Claim
18 words
The dispenser package of claim 2 wherein said narrow areas are two acute angles having one common side.
Claim 5
Dependent Claim
65 words
The dispenser package of claim 3 wherein said first part of the orifice has a profile shape of a wide stem funnel and said second part of the orifice has a profile shape of a narrow stem funnel with its funnel mouth opening at least generally corresponding in size and being in registration with said wide stem portion of said first part of the orifice.
Claim 6
Dependent Claim
14 words
The dispenser package of claim 2 wherein said severable sheet material are thermoplastic bags.
Claim 7
Dependent Claim
15 words
The dispenser of claim 5 wherein said bags are severable at transverse perforations between bags.
Claim 8
Dependent Claim
16 words
The dispenser of claim 6 wherein said bags are collected in a coreless convoluted winding thereof.
Claim 9
Dependent Claim
59 words
The dispenser of claim 7 wherein said coreless winding has a comparatively large diameter and a comparatively small diameter in the same plane, which winding, when in position in said container, assumes an oval shape with the center thereof being of such a size and shape so as to permit pay-out of the inner most bag through said orifice.
Claim 10
Dependent Claim
21 words
The dispenser of claim 8 wherein said orifice is in container walls which are parallel to the axis-line of said winding.
Claim 11
Independent Claim
214 words
A method for dispensing severable sheet material comprising providing a dispenser container including therein a collection of sheet material and providing at least one unitary, multi-functional dispensing orifice in the container, said orifice having an intercommunicating first part and second part, the first part being in one wall of the container and the second part being in another contiguous wall of the container, said first part having a periphery which defines a comparatively broad area, said first part periphery also defines a plurality of comparatively narrow areas, said first part periphery narrowing and merging with said second part, said second part having a periphery which also defines an area narrower than the region of merging and being remote from all other areas; said sheet material comprising a plurality of individually severable sheet materials, said members being defined by transverse pre-weakened regions, said collection, because of its shape and position within said container not being rotatable, said collection having an end portion located adjacent said orifice so as to be comparatively easily pulled therethrough by two fingers, pulling a sheet member through said orifice to a point beyond said pre-weakened region and pulling the sheet member into a narrow area with a sudden force sufficient to cause separation of said sheet at said pre-weakened region.
Claim 12
