Abstract

A package containing a plurality of disposable absorbent articles, the package being formed of flexible polymeric film, and having a path of perforations or scoring defining a hood opening structure is disclosed. The hood may be configured so as to serve as an effective package reclosure device whereby the package may be used to store the unused supply of articles following opening.

First claim

We claim:

1. A package formed of flexible polymeric film, containing a stack of folded disposable absorbent articles,
the stack having an approximate rectangular cuboid shape and comprising:
a plurality of the articles, similarly folded, each of the plurality of folded articles comprising: two opposing faces lying along approximately parallel planes; a lateral fold with a fold nose defining an end edge of the folded article, the fold nose having a pair of fold nose corners at left and right sides; a folded height, and a folded width;
the plurality of the articles being arranged with a face of one in contact with a face of the next adjacent one, and wherein the fold noses of a majority of the plurality are disposed approximately along a first side of the stack;
a stacking direction approximately perpendicular to the parallel planes;
a stack length measured from a first outward-facing side of a first article in the stack to an opposing second outward-facing side of a last article in the stack, along the stacking direction;
a stack height approximately corresponding to the folded height;
a stack width approximately corresponding to the folded width; and
a second side of the stack opposing the first side of the stack;

the flexible polymeric film enclosing and wrapping the stack and thereby approximately assuming the approximate rectangular cuboid shape and forming the package, the package thereby having six outward-facing surfaces comprising:
a first package surface adjacent one of the first side and second side;
a second package surface opposite the first package surface;
an opposing pair of third and fourth package surfaces respectively adjacent the first and second outward-facing sides; and
an opposing pair of fifth and sixth package surfaces respectively adjacent side edges of the articles in the stack;

the package having:
a package length approximately corresponding to the stack length, and a package width approximately corresponding to the stack width;
a path of perforations or scoring in the film beginning at a first endpoint and ending at a second endpoint, the path:
extending along a stack direction path length that comprises at least 33 percent of the package length;
having a first central portion extending across the entirety of one of the third and fourth package surfaces, connected to a second portion extending from a first connection with the first central portion, across a part of one of the fifth and sixth package surfaces to the first endpoint, and connected to a third portion extending from a second connection with the first central portion, across a part of the other of the fifth and sixth package surfaces to the second endpoint; and
defining an opening hood structure that overlays a set of the fold noses, the hood having a hood height of at least 40 mm,
the opening hood structure being disposed proximate the first side of the stack;
said package comprising an intact support band about the perimeter of the package extending across of each of the third, fourth, fifth and sixth package surfaces, circumscribing the stack along a support plane approximately parallel to the first outward-facing side of the stack and the support band located at a support band height of at least 50 percent of the stack height.

2. The package of claim 1 wherein said path of perforations has a cut-to-land ratio of at least 0.67:1 and no greater than 3:1.

3. The package of claim 1 wherein the film comprises multiple layers.
