Abstract
The present invention relates generally to a thermoplastic packaging bag having a carrying handle and relates specifically to a packaging bag having a separate carrying handle. After the bag is loaded with product and closed, the closure securely attaches the handle to the bag.
Claims21
A bag comprising:
- (a) front and rear panels of a thermoplastic material superimposed one against the other and defining a front and rear of a bag pocket, the panels joined to each other at respective longitudinal side edges to form bag pocket side edges and the panels having common ends including:
- (i) a first bottom end, the first end having a first continuous joint forming a closed bottom end;
- and
- (i) an opposite open mouth end;
- and
- (b) a separate handle, having ends and a middle, the separate handle attached at its ends to one of the bag panels near the open mouth end, each end of the handle having a contiguous depending portion extending to the middle of the handle, and such that when said contiguous depending portions are in an unfolded position, said middle is positioned below said closed bottom end and said contiguous depending portions extend toward the closed bottom end.

A bag comprising:
- (a) front and rear panels of a thermoplastic film joined to each other at respective longitudinal edges;
- (b) an open mouth end;
- (c) a closed bottom end formed by a heat seal connecting the bag panels, the seal extending transverse to the panels from one longitudinal side edge to another, forming a pocket to receive a product inserted through the open mouth end;
- (d) a separate handle, having ends and a middle, such that the handle is attached at its ends to one of the bag panels near the open mouth end, each end of the handle having a contiguous depending portion extending to the middle of the handle, and such that when said contiguous depending portions are in an unfolded position, said middle is positioned below said closed bottom end and said contiguous depending portions extend toward the closed bottom end.
1 more element
A method of making a thermoplastic bag having a separate attached carrying handle comprising:
- (1) providing front and rear bag panels of a thermoplastic heat sealable material superimposed one against the other, the panels being joined to each other at respective side edges to form sides of a bag pocket, the panels having common ends including a first bottom end and an opposite open mouth end, the first bottom end defining a closed bottom end of the bag pocket;
- and
- (2) attaching a handle, the handle having ends and a middle, to the bag by attaching the ends to one of the bag panels near the open mouth end, each end of the handle further having a contiguous depending portion extending to the middle of the handle, and such that when said contiguous depending portions are in an unfolded position, said middle is positioned below said closed bottom end and said contiguous depending portions extend toward the closed bottom end.
A method of making a product containing package with separate attached carrying handle comprising:
- (a) providing a bag having front and rear panels of a thermoplastic film, the panels being joined to each other at respective side edges to form sides of a product-receiving bag pocket, the bag having:
- (i) a closed bag pocket bottom end formed by a transverse heat seal contoured to accommodate an end of a product inserted into the bag pocket through an open mouth end opposite the closed bag pocket bottom end, and
- (ii) a handle, having ends and a middle, the handle attached at its ends to one of the bag panels at the mouth end, and optionally attached at its middle to said one bag panel, each end of the handle further having a contiguous depending portion extending to the middle of the handle, and such that when said contiguous depending portions are in an unfolded position, said middle is positioned below said closed bottom end;
- (b) inserting a product through the open mouth end;
- (c) evacuating the bag to collapse it about the product;
- (d) activating a means for closing to
- (i) close the bag open mouth end and, at the same time,
- (ii) attach the ends of the handle to the bag;
- (e) heat shrinking the product containing bag;
- and
- (f) pulling the handle up and over the mouth end thereby providing a handle for gripping and lifting said product-containing package.
