ABSTRACT:

TECHNICAL FIELD OF THE INVENTION
The invention relates to cartons, and more particularly, to cartons having a reinforced handle structure that enhances carton integrity and appearance.
BACKGROUND OF THE INVENTION
Handles are useful in cartons as a means for transporting the cartons. A problem in cartons of flexible material wherein a handle is formed in a panel of the carton is that the substantial stress forces are typically concentrated upon the handle or undesirable portions of the panel in which the handle resides. It can be appreciated that it ould be desirable to have a handle structure for a carton of flexible material that does not impart significant forces upon undesirable portions of the handle or the panel in which the handle resides.
It is often desirable to have a carton that presents walls that are as aesthetically appealing as possible to potential purchasers of the package formed by the carton. Thus, it can be appreciated that it would be desirable to have a carton with a handle structure that functions within a carton wall or panel that is also aesthetically appealing.
SUMMARY OF THE INVENTION
According to a preferred embodiment of the invention, a handle structure for a carton is formed within a panel having a opposing side edges and opposing end edges that intersect to form corners of the handle panel, the handle structure. A strap member is integrally conjoined with the handle panel and extends between the end edges. Opposing strap edges are substantially disjoined from the handle panel. The strap member includes a substantially centrally disposed region wherein opposing central strap edge segments of the opposing strap edges are substantially parallel to and mediate the opposing side edges. A severance line segment is disposed proximate each of the corners of the handle panel extending from a first end point proximate an associated one of the corners to a second end point proximate the centrally disposed region of the strap member such that when a force that is substantially normal to a plane in which the handle panels lies is exerted upon the centrally disposed region, the strap member is flexed substantially outwardly of the plane from a biased position proximate the plane.
Other advantages and objects of the present invention will be apparent from the following description, the accompanying drawings, and the appended claims.
