Abstract
Abstract A multiple container package for consumer direction with filled containers and for return direction with empty containers; the containers, such as cans or bottles, being of the type having a reduced generally cylindrical neck portion with an outward shoulder or bead formation below the neck opening; and including a resilient and deformable plastic carrier sheet positioning the containers in the packaged array by means of bands presenting apertures in the carrier sheet receiving the neck portions and with edges of the bands engaging beneath the shoulder or bead formations, and with tabs projecting laterally outwardly from opposite edges of the carrier sheet adjacent the apertures so that upon association of the neck portions with the band apertures, the tabs and carrier material along these outer edges will assume the curvature of the container neck portions with minimum stretching and tendency toward taking a set during storage and shelf life of the filled containers and with the tabs to deflect sharply downwardly into snug engagement with adjacent surfaces of the neck portions, and leaving sufficient resiliency in the material at least along the outer edges of the apertures enabling adequate support of an array of empty containers associated with the carrier sheet for return thereof to source for sterilizing, re-filling and re-closing of the returned containers.

Claim 1
Independent Claim
252 words
A package of closely spaced containers each of the type having a reduced generally cylindrical neck portion with outward shoulder means below the dispensing opening: and a carrier sheet of resilient deformable plastic material with apertures spaced in accordance with the number and spacing of the packaged containers and providing encircling bands receiving the neck portions of corresponding containers with edge portions of the apertures deflected upwardly and engaged beneath the shoulder means of included containers; each aperture having at least one portion of the periphery thereof of substantial length generally approaching a straight line and at least approximating the maximum length of an included aperture; the material of the carrier sheet adjacent said one portion of the periphery of each aperture extending transversely outwardly into a finger gripping tab including a base portion as part of the encircling band; each tab having a width along the base portion thereof substantially coextensively spanning said one portion of the periphery of an adjacent aperture and an outwardly extending length dimension from said base portion relative to other portions of the carrier sheet material making up the encircling bands surrounding each aperture such as to provide increased transverse extent of material outwardly from said base portion for maximum resistance to stretching of each said one portion of the periphery of each aperture with a sharp downward deflection of each tab in external contiguous surface continuation of the upwardly deflected base portion against the neck portion of an adjacent container in the package of containers.
Claim 2
Dependent Claim
252 words
A package of closely spaced containers each of the type having a reduced generally cylindrical neck portion with outward shoulder means below the dispensing opening: and a carrier sheet of resilient deformable plastic material with apertures spaced in accordance with the number and spacing of the packaged containers and providing encircling bands receiving the neck portions of corresponding containers with edge portions of the apertures deflected upwardly and engaged beneath the shoulder means of included containers; each aperture having at least one portion of the periphery thereof of substantial length generally approaching a straight line and at least approximating the maximum length of an included aperture; the material of the carrier sheet adjacent said one portion of the periphery of each aperture extending transversely outwardly into a finger gripping tab including a base portion as part of the encircling band; each tab having a width along the base portion thereof substantially coextensively spanning said one portion of the periphery of an adjacent aperture and an outwardly extending length dimension from said base portion relative to other portions of the carrier sheet material making up the encircling bands surrounding each aperture such as to provide increased transverse extent of material outwardly from said base portion for maximum resistance to stretching of each said one portion of the periphery of each aperture with a sharp downward deflection of each tab in external contiguous surface continuation of the upwardly deflected base portion against the neck portion of an adjacent container in the package of containers.
Claim 3
Dependent Claim
244 words
A carrier for rows of containers each of the type having a reduced neck portion presenting outward shoulder means adjacent the dispensing end thereof; and comprising a carrier sheet of resilient, deformable plastic material with apertures spaced in accordance with the number and spacing of the containers and providing encircling bands to receive the neck portions of the containers to be packaged; each aperture having at least one portion of the periphery thereof of substantial length generally approaching a straight line and at least approximating the maximum length of an included aperture; the material of the carrier sheet adjacent said one portion of the periphery of each aperture extending transversely outwardly into a finger gripping tab including a base portion as part of the encircling band; each tab having a width along the base portion thereof substantially coextensively spanning said one portion of the periphery of an adjacent aperture and an outwardly extending length dimension from said base portion relative to other portions of the carrier sheet material making up the encircling bands surrounding each aperture such as to provide increased transverse extent of material outwardly from said base portion for maximum resistance to stretching of each said one portion of the periphery of each aperture with a sharp downward deflection of each tab in external contiguous surface continuation of the upwardly deflected base portion against the neck portion of an adjacent container when the containers are assembled with the carrier in package form.
Claim 4
Dependent Claim
244 words
A carrier for rows of containers each of the type having a reduced neck portion presenting outward shoulder means adjacent the dispensing end thereof; and comprising a carrier sheet of resilient, deformable plastic material with apertures spaced in accordance with the number and spacing of the containers and providing encircling bands to receive the neck portions of the containers to be packaged; each aperture having at least one portion of the periphery thereof of substantial length generally approaching a straight line and at least approximating the maximum length of an included aperture; the material of the carrier sheet adjacent said one portion of the periphery of each aperture extending transversely outwardly into a finger gripping tab including a base portion as part of the encircling band; each tab having a width along the base portion thereof substantially coextensively spanning said one portion of the periphery of an adjacent aperture and an outwardly extending length dimension from said base portion relative to other portions of the carrier sheet material making up the encircling bands surrounding each aperture such as to provide increased transverse extent of material outwardly from said base portion for maximum resistance to stretching of each said one portion of the periphery of each aperture with a sharp downward deflection of each tab in external contiguous surface continuation of the upwardly deflected base portion against the neck portion of an adjacent container when the containers are assembled with the carrier in package form.
