Definitions
- the present invention is directed to reinforced bags for carrying articles.
- the present invention is for reinforced bags as more fully set forth herein.
- the invention is directed to a bag having two exterior faces, an open mouth end defined by the exterior faces, a sealed bottom end joining the exterior faces, at least one gusset extending between the mouth end and the sealed bottom end and defining an inner gusset point, and at least one tab affixed to the bag at the location where an inner gusset point intersects the bottom seal, wherein the tab is formed from bag material.
- the bag may have handles and a handle cut-out region and the tab may be formed from a removed handle -mouth portion of a bag.
- the invention is directed to a method for reinforcing a gusseted bag, the process comprising the steps of cutting a tab from bag material, and affixing at least one tab to the gusseted bag at a location at which an inner gusset point of the bag intersects with a bottom seal of the bag
- Another method for manufacturing a reinforced gusseted bag is comprised of the steps of forming a plastic tube, gusseting the plastic tube to form at least a first gusset, cutting a portion of tubing to form a tab, wherein the tab is cut from the tubing on three sides, folding the tab about its uncut side to overlay the bag at the point where an inner gusset of the first gusset will intersect with a heat seal, and forming a heat seal on the plastic tube to form a bottom seal end of a bag.
- DE 8807896 U discloses a bag having a separate and perforated rectangular flag that is connected to the bag by a weld seam.
- GB 1,088,385 discloses a process for manufacturing bags with gussets by folding, wherein the bags have a folded end.
- US 5,562,580 discloses polyethylene bag stacks and methods for their manufacture, wherein the bags have a self-opening feature.
- bag 100 which is illustrated as a t-shirt-type bag, is shown. As illustrated, bag 100 has an open mouth end 102 and a sealed bottom end 104 at opposing longitudinal ends. In some embodiments, sealed bottom end 104 may be formed by a heat seal. Bag 100 also includes faces 106 (with a front face shown and a rear face, not shown, on the rear side of the bag). Bag 100 also has laterally-spaced, upwardly extending handle portions 108. Such handles may be formed by removing a portion of material from a collapsed tube of plastic otherwise having a "pillowcase” shape to form a "u-shaped" portion that results in the handles and mouth end 102 of bag 100.
- Each handle portion 108 may include an aperture portion 110 for mounting a bag or a stack of bags on a dispensing rack system.
- bag 100 may include a central tab 112 having a slit or aperture 114 for mounting the bag on a dispensing rack system.
- central tab 112 may be integral to bag 100 while in other embodiments central tab 112 may be detachably connected to bag 100, such as by way of a perforation line or an aperture that separates central tab 112 from bag 100 upon tearing.
- bag 100 also includes gussets 116, which have an inner gusset point 116'. Bag 100 is shown in a closed configuration in which the bag is not opened, i.e., front and rear faces 106 are back-to-back and the gussets are not open.
- the gusseted portions of bag 100 include four plies (or layers) film when the bag is viewed from a side or end and the region between the gusseted portions includes two plies.
- a heat seal or other seal-forming sealed bottom end 104 must seal differing amounts of layers across the bottom of the bag.
- locations at which uneven layers of a bag are sealed at the bottom of a bag such as shown by points A in Fig. 1A , may be weak and subject to tearing. Such tearing may result in decreased bag performance and even bag failure.
- Embodiments of the present invention provide reinforced bags.
- bag material is used to reinforce a bag.
- bag material references material having the same composition as the bag.
- bag material may be scrap or waste from the manufacture of a particular bag, wherein the scrap includes portions of bags that have been discarded during a bag manufacturing processes.
- material may be removed from a bag being manufactured to form the "u-shaped" cut-out area, which forms the handles and mouth of a bag.
- such removed material in that region is referenced as the "removed handle-mouth portion", and such portions may be used as the bag material for reinforcement.
- tabs may be prepared from bag materials, such as the u-shaped cut-out discussed above, and one or more tabs may be affixed to a bag, such as at a weak spot, to reinforce the bag.
- Such tabs may be of any suitable shape, such as, without limitation, circular, semi-circular, square, rectangular, or triangular.
- such tabs may be of any suitable size for any given application.
- FIG. 2 depicts an exemplary embodiment of a reinforced bag of the present invention.
- bag 200 as illustrated in Fig. 1 has tabs 250 affixed at each of point A, which are known to be a weak spot during use due to the varying layers sealed together at the bottom of the bag.
- tabs 250 may have a generally circular shape and wrap around the sealed bottom end 104 of bag 100 to provide a semi-circular portion on each bag face. The depicted tabs may be cut from the removed handle-mouth portion that was removed from the bag during its manufacture.
- Figs. 3A-3C illustrate an alternative embodiment of the present invention.
- bag 300 includes tabs 350, each of which has a generally semi-circular shape (as shown in the expanded view) as opposed to being a full circle.
- this exemplary embodiment shows one tab affixed to bag 100 on each side of point A such that tabs 350 do not overlap the bottom of bag 100.
- tabs may be used in other embodiments.
- square-shaped, rectangular-shaped, triangular-shaped, and various elongated-shaped tabs are all among the exemplary shapes that may be employed.
- some embodiments may include additional tabs.
- a tab may be affixed and positioned on a bag to reinforce more than one weak point of the bag.
- multiple tabs may be applied to a single weak point.
- a bag may have a portion of material that extends below the sealed bottom of the bag.
- a tab may be affixed to such portion of the bag.
- a tab may wrap around such portion in the manner described above.
- the present invention also includes an additional method for reinforcing bag.
- bags may be formed from a tube of plastic, such as by gusseting the plastic tube, heat sealing the tube to form a bottom of the bag, and removing the removed handle-mouth portion to form handles and a mouth of the bag.
- bags may be cut or perforated from the adjacent portions of the plastic tube, which is used to form bags in the same manner.
- bag 500 and bag 600 are adjacent and connected, such as may be the case during the manufacture of plastic bags from a tube of plastic film.
- bag 500 is shown having sealed bottom end 504, gussets 516, and inner gusset points 516'.
- bag 600 is shown having gussets 616, inner gusset points 616', open mouth end 602, handle portions 608, a top seal 603, and removed handle-mouth portion 609 (in which removed handle-mouth portion 609 has not yet been removed from the tube from which bag 609 will be formed).
- Tear line 511 separates bag 500 and bag 600, and tear line 609 may be a cut line or a perforated line (and in some embodiments tear line 511 may not be formed until after tab 550 is formed and affixed as described below).
- tab 550 may be cut in the manner shown in Fig. 4 , in which three sides (indicated as X, Y, and Z) 550 are cut from the bag material below sealed bottom end 504 and from bag material from removed handle-mouth portion 609 (prior to its removal from the bag) to form tab 550. Then, tab 550 may be folded about its uncut edge and affixed to bag 500 at the junction of inner gusset point 516' and sealed bottom end 504 (as indicated by the cross-hatched region in Fig. 4 ). In this regard, for descriptive purposes only, Fig. 4 illustrates both the cut lines X, Y, and Z for tab 550 and tab 550 as affixed to bag 500. In alternative embodiments, removed handle-mouth portion 609 could be cut in a shape to form tab 550 without additional cutting. In addition, tab 550 may be folded either before or after sealed bottom end 504 is formed.
- tab 550 may be folded along the tear line 511 such that tab 550 is formed solely from bag material from removed handle-mouth portion 609 of bag 600.
- tab 550 may be formed solely from bag material located below sealed bottom end 504 of bag 500 and tear line 511, such that tab 550 is formed from bag material taken solely from bag 500.
- tab 550 may be cut on three sides and folded as described above.
- bag material described herein may be entirely cut on all sides and then removed and affixed to a bag.
- tabs 550 are formed by cutting only three sides of the tab and then folding and affixing it in the cross-hatched region. In some embodiments, tabs 550 may be formed and affixed on both the front and a back side of a bag (wherein the back side is not shown in Fig. 4 ).
- Fig. 5 depicts an additional embodiment of the present invention and a method of its manufacture.
- a bag 700 has a tab 750 that is composed of bag material and that extends to span across the two gusset points depicted.
- the area of the adjacent bag in the manufacturing process from which bag material for tab 750 is taken may ultimately become a removed handle-mouth region.
- the manufacturing steps may be practiced in the following order:
- tabs of the present invention may be affixed to a bag using any conventional practices or materials.
- tabs may be heated and melded to a bag.
- tabs may be attached by adhesives, stitching, heat sealing, or using any other suitable methods or combination of methods.
- bag stacks also called bag packs, in which a plurality of bags are stacked adjacently.
- Bag stacks may contain any number of bags that are reinforced as described herein and, in some exemplary embodiments, a bag stack may contain 50 bags, 100 bags, or more bags.
- Bags and bag stacks of the present invention may be made using any conventional techniques known in the art, such as those described in U.S. Patent No. 5,335,788 and U.S. Patent No. 5,562, 580 .
