Abstract

A package, which can be substantially hexahedral, is composed of a flexible polymer material and contains a plurality of articles. The package includes a front face wall, a back face wall, a top wall, a bottom wall and two oppositely located end walls. A plurality of stacks of the articles are contained within the package, and the article stacks arranged to extend in a generally parallel, side-by-side configuration with each stack including a multiplicity of the articles. Each of the stacks is aligned along an appointed stacking direction of the package, and each of the stacks has opposed facing ends thereof contacting opposed walls of the package. A designated opening mechanism extends across a selected primary opening wall of the package and extends across at least a portion of each of a pair of oppositely located, complementary opening walls of the package. The opening mechanism provides for a selected separation of the primary and complementary opening walls, and is positioned at a location which may be substantially between a pair of separable immediately adjacent arrays of stacked articles, thereby providing for a separation of the package into at least a pair of subpackages, with each subpackage containing at least a portion of at least one article stack therein while exposing a side portion of the at least one article stack for grasping.

Claims22

Dependent claims

A package, which is composed of a flexible polymer material and contains a plurality of articles, comprising:

a front face wall defining a top edge region, a bottom edge region and two opposed side edge regions thereof;
a back face wall defining a top edge region, a bottom edge region and two opposed side edge regions thereof;
a top wall which interconnects between the top edge regions of said front and back walls, and includes a pair of oppositely located side edge regions thereof;
a bottom wall which interconnects between the bottom edge regions of said front and back walls and includes a pair of oppositely located side edge regions thereof;
two oppositely located end walls each of which interconnects between a side edge region of said front wall and a side edge region of said back wall, and interconnects between a side edge region of said top wall and a side edge region of said bottom wall;
a plurality of stacks of said articles contained within said package, said article stacks arranged to extend in a generally parallel, side-by-side configuration with each stack including a multiplicity of said articles, each of said stacks aligned along an appointed stacking direction of said package, and each of said stacks having opposed facing ends thereof contacting opposed walls of said package, thereby identifying said contacted opposed walls as appointed abutment walls of said package;
a designated opening means which extends across a selected primary opening wall of said package and extends at least partially across each of a pair of oppositely located, complementary opening walls of said package, said opening means providing for a selected separation of said primary and complementary opening walls, and said opening means positioned along said primary and complementary opening walls at a location which is positioned substantially between separable, immediately adjacent arrays of stacked articles, thereby providing for a separation of said package into at least a pair of subpackages, with each subpackage containing at least a portion of at least one article stack therein while exposing a portion of said at least one article stack for grasping;
and
at least one supplemental handle member connected to said package in a substantially inoperable storage condition and activatable to an operable handle condition, said at least one supplemental handle member integrally formed with said front wall or said back wall when said at least one supplemental handle member is in its storage condition and provided by a supplemental frangible line which runs substantially parallel to said designated opening means, said at least one supplemental handle member thereby activatable to bridge over said exposed article stack portion.

A bag composed of a flexible polymer material for holding a plurality of articles, said bag comprising:

a bag front panel defining a top edge region, a bottom edge region and two opposed side edge regions thereof;
a bag back panel defining a top edge region, a bottom edge region and two opposed side edge regions thereof which connect to said side edge regions of said front panel;
a bag gusset panel which interconnects between the top edge regions of said front and back panels;
a designated opening means which extends at least partially across one of said front and back panels and continues therefrom to extend at least partially across another of said front and back panels, wherein said opening means provides for a selected separation of said bag panels and is positioned to provide a dividing line located substantially between separable, adjacent stacked arrays of said articles, thereby providing for a separation of said bag into at least a pair of bag subsections, with each subsection appointed to thereby contain at least a portion of at least one article stack therein while exposing a region of said at least one article stack for grasping;
and
at least one supplemental handle member connected to said bag in a substantially inoperable storage condition and activatable to an operable handle condition, said at least one supplemental handle member integrally formed with said bag front panel or said bag back panel when said at least one supplemental handle member is in its storage condition and provided by a supplemental frangible line which runs substantially parallel to said designated opening means, said at least one supplemental handle member thereby activatable to bridge over said exposed article stack region.

A bag composed of a flexible polymer material for holding a plurality of articles, said bag comprising:

a bag front panel defining a top edge region, a bottom edge region and two opposed side edge regions thereof;
a bag back panel defining a top edge region, a bottom edge region and two opposed side edge regions thereof;
an opposed pair of bag side gusset panels which interconnect between the side edge regions of said front and back panels;
a designated opening means which extends across at least one of said front and back panels and continues therefrom to extend at least partially across each of said side gusset panels, said opening means providing for a selected separation of said bag, and said opening means positioned along said bag panels at a region which is appointed for placement substantially intermediate a pair of adjacent stacked arrays of said articles, thereby providing for a separation of said bag into at least a pair of appointed bag subsections, with each subsection appointed to contain at least a portion of at least one complete article stack therein while exposing a region of said at least one article stack for grasping;
and
at least one supplemental handle member connected to said bag in a substantially inoperable storage condition and activatable to an operable handle condition, said at least one supplemental handle member integrally formed with said front panel or said back panel when said at least one supplemental handle member is in its storage condition and provided by a supplemental frangible line which runs substantially parallel to said designated opening means, said at least one supplemental handle member thereby activatable to bridge over said exposed article stack region.
