Description
- This application claims priority under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application No. 60/809,980 filed Jun. 1, 2006.
- Not Applicable.
- The present disclosure relates to handle assemblies for pourable packages. In particular, the present disclosure relates to handles attached to a side gusset of a package in the form of a flexible bag. The flexible bag can be plastic or paper. The present disclosure also relates to methods of attaching the handle assembly to the flexible bag.
- The configuration of current handles for flexible bags results in inconvenient and inefficient handling or pouring of the bag's contents. Since these handles attach to sides of the bags, these handles tear away from the bag when the user pours contents from the bags as the content's weight applies a force to the interface of the handles and the bag. Furthermore, these handles provide edges at the bag interface that allow for contamination exposure to the bag's contents. It is imperative that bags retain a strong construction without any areas of contamination.
- Additionally, current handles do not fold within the sides of the bag. As such, these handles remain exposed during non-use of the bag, such as during manufacturing of the bag or during storage of the bag, leading to tearing and/or fraying of the handles. Consumers need a handle that can be internally sealed to the gusset of the bag to assist in efficiently pouring contents from the bag without providing contamination exposure to the bag. Additionally, consumers need a handle that attaches to a gusset of the bag without tearing or separating from the bag as the contents pour from the bag or as the consumer holds the bag.
- The present disclosure relates to a handle assembly that internally seals to a side gusset of a package to assist in efficiently pouring contents from the package without providing contamination exposure to the package and without separating from the package. The handle assembly attaches within an opening of the side gusset.
- The handle assembly comprises hand portions, each hand portion having a tab that extends beyond the opening and along an inside wall of the side gusset. The handle assembly further comprises a seal member positioned on the inside wall of the side gusset and around the opening wherein the seal member seals the tabs to the inside wall of the side gusset and seals the opening. The hand portions fold within the side gusset when the side gusset collapses to a retracted position and the hand portions extend beyond the side gusset when the side gusset opens to an expanded position.

- The following detailed description illustrates the disclosure by way of example and not by way of limitation. The description clearly enables one skilled in the art to make and use the disclosure, describes several embodiments, adaptations, variations, alternatives, and uses of the disclosure, including what is presently believed to be the best mode of carrying out the disclosure.
- The terms “bag” and “package” are used interchangeably wherein the bag/package may comprise a rigid construction, a semi-rigid construction and a non-rigid construction.
- Referring to the drawings, a package A in the form of a
flexible bag 10 comprises ahandle assembly 12 internally sealed to the flexible bag 10 (FIG. 1 ). Theflexible bag 10 includes afront panel 14, aback panel 16, abottom panel 18 and opposing side gussets 20. Eachside gusset 20 further includes an inside wall 22 (FIG. 2 ) and anoutside wall 24. Additionally, at least one of theside gussets 20 has a gusset opening 26 (FIG. 6 ) positioned therethrough. Theflexible bag 10 and thehandle assembly 12 may comprise a plastic material. - As shown in
FIGS. 1 and 2 , thehandle assembly 12 compriseshand portions 28 and aseal member 30. Turning toFIG. 3 , thehand portion 28 includes atop 32 withrounded corners 34 and astraight bottom 36. In an embodiment, therounded corners 34 have a radius of curvature from about 0.8 inches to about one inch and the bottom has a measurement from about four inches to about six inches. Near thebottom 36, thehand portion 28 includes atab 38 configured to fold outwardly with respect to thetop 32 as will be discussed. Further, as shown, eachhand portion 28 includes an opening 40 havingrounded finger areas 42. In one embodiment, therounded finger areas 42 have a radius of curvature measured from about 0.25 inches to about 0.50 inches. Additionally, eachhand portion 28 includes afold line 44 to allow thehand portion 28 to fold upon itself. - In one embodiment, the
hand portions 28 utilize plastic film that is die-cut as illustrated inFIG. 4 . As shown, thetops 32 of thehand portions 28 connect to each other. The film comprises a material strong enough to prevent ripping or tearing. In an embodiment (not shown), the film includes a coating on one side with a heat activated bonding layer. The hand opening 40 is cut within thehand portion 28 with thefinger areas 42 at both ends. The top 32 of the hand opening 40 however is left uncut. By not cutting the top 32 edge, thehandle assembly 12 is stronger and more comfortable to the user. Comfort is created with interior material of thehand portion 28 being folded over as the user's hand grasps thehand portions 28. The folded material prevents discomfort from a sharp edge if the hand opening 40 were to be totally removed. - Referring to
FIGS. 5 and 6 , the gusset opening 26 is defined through the centerfold of theside gusset 20 to guide thetabs 38 of thehand portions 28 within theflexible bag 10. The length of the gusset opening 26 may equal the length of thehand portion 28. As shown inFIG. 6 , thehandle assembly 12 partially positions within the gusset opening 26 and partially positions beyond the gusset opening 26. Thetabs 38 of thehand portions 28 extend through theopening 26 and along theinside wall 22 of theside gusset 20. As shown, thetabs 38 outwardly extend from theopening 26 in opposing directions and along theinside wall 22 of theside gusset 20. In an embodiment, thetabs 38 extend along theinside wall 22 at a distance of about 0.25 inches to about 0.75 inches as measured from theopening 26. In another embodiment, thetabs 38 extend along theinside wall 22 at a distance of about 0.50 inches as measured from theopening 26. - The
seal member 30 is positioned on theinside wall 22 of theside gusset 20 wherein the length of theseal member 30 extends beyond the length of thetabs 38. Additionally, theseal member 30 is positioned around theopening 26. As shown inFIG. 6 , thetabs 38 position between theinside wall 22 of theside gusset 20 and theseal member 30. Once theseal member 30 is properly positioned within theflexible bag 10, theseal member 30 is heat bonded to both thetabs 38 and theinside wall 22 to seal thetabs 38 to theinside wall 22 and to seal the opening 26 (FIG. 7 ). In one embodiment, the heat sealing includes a heat activated coating compatible with both theflexible bag 10 and thehandle assembly 12. Sealing thismember 30 insures that thehandle assembly 12 securely attaches to theflexible bag 10 and insures integrity of theflexible bag 10 by covering thegusset opening 26. As such, without theseal member 30, thehandle assembly 12 would separate where it passes through theopening 26 because the sides of thehandle assembly 12 are not bonded together. - The size of the
handle assembly 12 and the folding patterns of the fold lines 44 are such that thehand portions 28, when folded flat, are completely enclosed within theside gusset 20 when theflexible bag 10 is folded flat (FIG. 8 ). Thehand portions 28 fold along the fold lines 44 such that thehand portions 28 position within theside gusset 20 when theside gusset 20 collapses to a retracted position. In the retracted position, theside gusset 20 encloses thehand portion 28. Thehand portion 28 remains flat against theside gusset 20 when theflexible bag 10 is opened and is filled with the desired content. The user then pulls thehand portion 28 away from theside gusset 20 enabling thehandle assembly 12 to be used in an expanded position. In the expanded position, thehand portions 28 extend beyond theside gusset 20. - Since the
handle assembly 12 is sealed to theflexible bag 10, the user can easily and effectively pour contents out of theflexible bag 10 while maintaining the integrity of the interface of thehandle assembly 12 and the flexible bag 10 (FIG. 9 ). Furthermore, the sealedhandle assembly 12 eliminates edges prone to contamination. Thehandle assembly 12 allows for convenient pouring out of a variety of heavy and light contents such as but not limited to dry granular products, cereal, flour and soap. - During manufacturing of the
handle assembly 12, the manufacturer die-cuts thehandle assembly 12 from a film or blank of plastic wherein this film comprises a material strong enough to prevent ripping or tearing. In one embodiment, the manufacturer may dispose a coating on one side of the plastic with the heat activated bonding layer. The manufacturer then forms thehand portion 28 by cutting the bottom and the radius of eachfinger area 42 from thehand opening 40. Next, the manufacturer forms thegusset opening 26 along the centerfold of at least one of theside gussets 20. Accordingly, thegusset opening 26 may be formed on both sides of theflexible bag 10 or on just one side of theflexible bag 10. The manufacturer may cut the length of thegusset opening 26 to equal the length of thehand portion 28 of thehandle assembly 12. - The
tabs 38 of thehand portions 28 are then inserted through thegusset opening 26 to position thetabs 38 next to and along theinside wall 22 of therespective side gusset 20. The manufacturer then folds outwardly eachtab 38 from thegusset opening 26. These unfoldedtabs 38 are then heat sealed to theinside wall 22 of theside gusset 20. The manufacturer then positions theseal member 30 inside theflexible bag 10 in a position opposite theinside wall 22 of theside gusset 20 of the now sealedtabs 38. Once theseal member 30 is properly positioned within theflexible bag 10, the manufacturer heat bonds theseal member 30 to both thetabs 38 and theinside wall 22 and in a configuration around theopening 26. - The manufacturer may then fold the
hand portions 28 along the fold lines 44 such that when thehand portions 28 are folded flat, theside gusset 20, in the retracted position, encloses thehand portions 28. In another embodiment, the manufacturer may leave thehand portion 28 protruding from the center of theside gusset 20 when theside gusset 20 folds flat or folds open. - Turning to
FIG. 10 , in another embodiment of thehandle assembly 12 of the present disclosure, thehand portions 28 can be constructed without the flat folding feature (FIG. 8 ). In this embodiment, thehand portion 28 protrudes from the center of theside gusset 20 when theside gusset 20 folds flat or folds opened. Theside gusset 20 extends somewhat beyond the bag edge when theflexible bag 10 is folded flat within theside gusset 20 having a width smaller than 4.25 inches. This embodiment is user-friendly by being readily usable rather than having to manually extend thehand portions 28 as with the folded approach. Theseal member 30 still maintains the integrity of the interface of thehandle assembly 12 and theflexible bag 10 while eliminating edges prone to contamination. - Still further, in another embodiment of a handle assembly of the present disclosure (not shown), the handle assembly bonds directly to the outside wall of the side gusset. In this embodiment, the tabs bond to the outside wall of the side gusset. As such, this embodiment eliminates slitting the flexible bag and eliminates using any seal member. Accordingly, eliminating these components reduces equipment costs associated with these components to achieve cost savings.
- Unlike plastic, paper is more prone to tearing. In addition, many paper bags are constructed with multiple layers. Many products packaged in paper bags have ingredients such as oil that will wick into the paper causing a stain thus having a negative affect on the graphics. The paper has a coating to prevent this from happening. However, contamination will occur through an exposed edge such a handle interface.
- A slit in a side gusset of an existing paper bag will weaken the bag structure, since tearing is likely to occur at the ends of the slit. Furthermore, the slit creates raw edges in the paper that may be exposed to the product; thus providing a scenario for contamination. As noted, it is imperative that the paper bag retains a strong construction without any potential areas of contamination.
- In another embodiment of the present disclosure (
FIG. 11 ), a flexible bag comprises apaper bag 46 wherein the handle assembly 12 (FIG. 12 ) is configured to attach to thepaper bag 46. Thepaper bag 46 comprises arectangular opening 48 defined through theside gusset 20, centered on thecenterfold 50 of thegusset 20. The position of theopening 48 is to be determined by the packager to achieve the desired performance. - Turing to
FIG. 12 , thepaper bag 46 further comprises twoseal members 52 placed over theopening 48, one on the inside and one on the outside. Theseal members 52 are centered over theopening 48 and sized to be larger than theopening 48. The material of theseal members 52 provides strength with resistance to tearing as well as withstanding contamination. In one embodiment, the seal material comprises a plastic laminate with a layer of polyester. Further, eachseal member 52 has a layer of heat-seal coating 54 on one side that is compatible with both the inside and outside of thepaper bag 46. Once theseal members 52 are in position, theseal members 52 are heat-sealed to thepaper bag 46, on both sides, as well as to each other in the area of theopening 48. - The attachment of the
seal members 52 to thepaper bag 46 and over the opening 48 seals the cut edges of theopening 48. As such, theseal members 52 provide the necessary strength to accept thehandle assembly 12 without tearing. Furthermore, the strength of theseal members 52 allow aslit 56 or opening to be positioned through theseal members 52, wherein theslit 56 accepts thehandle assembly 12. Theseal members 52,coatings 54 and slit 56 are shown in exaggerated form for clarity. - This slit 56 is placed down the center, centered vertically on the
seal members 52. The length of theslit 56 is determined by the width of thehandle assembly 12. The lengths of theseal members 52 andopening 48 are designed to provide ample length to accept theslit 56 without cutting into the top or bottom edge of theopening 48. Thetabs 38 of thehand portions 28 extend through theslit 56 and along theinside wall 22 of theside gusset 20 wherein anotherseal member 58 seals thetabs 38 to theinside wall 22 and seals theslit 56. - The
handle assembly 12 andflexible bag 10 of the present disclosure are cost effective to manufacture while maintaining integrity of theflexible bag 10. Thehandle assembly 12 is capable of mounting at an optimal position on theflexible bag 10 based on the dispensing requirements and weight of theflexible bag 10. Additionally, thehandle assembly 12 is capable of folding within theside gusset 20 wherein thehandle assembly 12 remains comfortable to use yet strong enough to handle the weight of the contents. - In view of the above, it will be seen that the several objects of the disclosure are achieved and other advantageous results are obtained. As various changes could be made in the above constructions without departing from the scope of the disclosure, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
