HEAVY-DUTY QUAD SEAL PLASTIC BAG WITH SIDE HANDLE HOLES
A heavy-duty plastic bag is comprised of a flat front panel, a back panel and gusseted longitudinal side panels. One of the gusseted longitudinal side panels has extended opposed gusseted side walls to form bag carrying end panels. The bag carrying end panels are sealed with one another and are each provided with three spaced-apart handle holes for ease of carrying the bag by one or both ends of a person with the bag disposed horizontally to facilitate manipulation in carrying of the bag. The bag carrying end panels provide for reinforced hand holes and comfort to the hands of a user person. The gusseted side panels and front and back panels provide a heavy-duty plastic bag with four display panels.

The present invention relates to a heavy-duty plastic bag which is provided with handle holes in an extended gusseted side wall and wherein the bag has four panels to display printed matter.
BACKGROUND ARTIt is known to form plastic bags with two or three handle holes provided in the top or bottom panels of the bags to facilitate carrying the bag or to facilitate pouring the contents of the bag. For example, a variety of bag constructions with two or three handle holes is described in U.S. Pat. Nos. 3,402,749, 5,782,562 and 6,361,209. In all instances the handle holes are provided in top or bottom end flanges of the bags and these are formed by opposed plies folded on one another. When these bags are used for carrying heavy contents, the bags are often dragged on the floor surface by these handle holes due to its weight and this can damage the bag and spill the contents. Further, these heavy-content bags are difficult to lift off the floor when lying flat due to their length. Also, depending on the construction of the handle holes with only one or two plies of film material, the handle holes can rip or cause discomfort to the hands of the user person.
Another disadvantage of these prior art bags is that they only provide two panels for displaying advertising material, namely the front and rear panels. However, bags carrying heavy contents are usually disposed lying flat in a stack placed on a floor pallet with only the side edges of the bag showing with the exception of the top bags which display the front or back panels of the bag but these are not often visible. There is therefore a need to provide a heavy-duty plastic bag which is easy to manipulate and carry, and which can display advertising material when the bags are stacked flat on one another and wherein the manipulation of the bag by the handles is not damaging to the hands of the user person.
SUMMARY OF INVENTIONIt is therefore a feature of the present invention to provide a heavy-duty plastic bag which is provided with gusseted longitudinal side panels capable of carrying display material and wherein one of the longitudinal gusseted side panels is formed with end panels having three handle holes to carry the bag horizontally by one or both hands of a user person.
Another feature of the present invention is to provide a heavy-duty plastic bag formed with gusseted longitudinal side panels having handle holes formed in reinforced extended opposed gusseted end panels thereof which are sealed to one another to form reinforced carrying end panels.
Another feature of the present invention is to provide a heavy-duty plastic bag having handle holes in a longitudinal side gusseted display panel thereof and which permits the carrying of the bag horizontally with the hands positioned at a comfortable height.
Another feature of the present invention is to provide a heavy-duty plastic bag designed to be displayed lying down on a storage shelf or stacked on a floor pallet.
Another feature of the present invention is to provide a heavy-duty plastic bag having four display panels and reinforced gusseted side panels which allows for the bag to carry more weight.
According to the above features, from a broad aspect, the present invention provides a heavy-duty plastic bag comprising a flat front panel, a flat back panel and gusseted longitudinal side panels. The bag has a top end and a bottom end adapted to be sealed for containing a product in the bag. The gusseted longitudinal side panels each have opposed gusseted side walls collapsible against one another on a side central fold line. One of the longitudinal side panels has extended opposed gusseted side walls to form bag carrying end panels. Seal means is provided to secure the bag carrying end panels with one another. Three spaced-apart handle holes are formed in the bag carrying end panels with the handle holes of each bag carrying end panel aligned with one another. One of the handle holes is disposed substantially at mid-length of the bag carrying end panels to constitute a central hand hole. The other two of the handle holes are substantially equidistantly spaced on opposed sides of the central hand hole. The hand holes permit the heavy-duty bag to be carried from the gusseted longitudinal side panel by the use of one or both hands of a person disposed through said hand holes with the bag extending horizontally.
A preferred embodiment of the present invention will now be described with reference to the accompanying drawings in which:
Referring now to the drawings and more particularly to
The bag 10 has a top end 15 and a bottom end 16 adapted to be sealed for containing a product in the bag and particularly heavy-duty products such as dog food, course salt, or other granular or heavy material. The gusseted longitudinal side panels 13 and 14 each have opposed gusseted side walls, herein side walls 13′ and 13″ for side gusset panel 13, and side walls 14′ and 14″ for side gusset panel 14. Each of the side walls 13′, 13″ and 14′, 14″ are collapsible against one another on side central fold lines 13′″ and 14′″, respectively.

It can be concluded from the above that the heavy-duty plastic bag construction of the present invention facilitates the handling and carrying of the bag by the use of one or both hands with the longitudinal axis of the bag lying in a horizontal plane. It also provides for four display panels whereby display material is visible when the bag is disposed lying flat on its side even in stacked bundles supported on floor pallets. The quad seal design of the side gusseted panels also provides reinforcements of these side panels and the bag carrying end panels of one side gusset is also reinforced with at least four plies of the multi-ply film providing for the bag to carry more weight and making it easier on the consumer hands to carry the bag.
It is within the ambit of the present invention to cover any obvious modifications of the preferred embodiment described herein, provided such modifications fall within the scope of the appended claims.
