Definitions

  • the present invention relates to handles for articles, and more particularly to handles for flexible bag structures.
  • Flexible bag structures have been employed for products with multiple discrete components that may be dispensed in a flowable state, such as dog food, cement, charcoal, or powdered substances. Such flexible bag structures are difficult to grasp, lift or carry since neither the bag or its contents provide any structural support. More recently, these difficulties have become of increased importance as the size and weight of bags and their contents have tended to increase in the marketplace. Such bags are currently being marketed with weights (including contents) of 40-50 pounds (88-110 kg) or more.
  • a handle for a bag structure is lightweight, inexpensive (since it is likely that the bag and the handle will be discarded after dispensing the contents), easily and quickly applied, unobtrusive prior to use, and securely attached to the bag during manipulation of the bag and its contents.
  • Tape handles may be devised for flexible bag structures that are less expensive, less obtrusive and easier to apply than the die cut or molded handles discussed above. However, such tape handles would be deficient in several respects.
  • a tape handle may be devised that includes a segment of pressure sensitive adhesive tape and a segment of deadening material applied to cover or mask an intermediate portion of the pressure sensitive adhesive side of the tape, with end portions of the pressure sensitive adhesive side of the tape segment remaining exposed for application to a bag.
  • the tape handle may be applied to a bag to form a loop protruding from the bag with the length of the loop equal to the length of the deadening material. The remaining portions of the pressure sensitive adhesive side of the tape segment are applied to and adhere to the bag.
  • a pressure sensitive adhesive tape typically exhibits that weakest bond strength to a surface when stressed in a peel mode, as compared to a shear mode.
  • Such conventional tape handles thus have an tendency to detach from the bag at an undesirably low level of force. This limits the container weight for which a particular handle may be used.
  • a tape handle according to the present invention generally designated by the reference numeral 10.
  • the tape handle of the present invention is for use with containers so that the handle may be easily grasped and the container manipulated (e.g. lifted or carried).
  • the handle of the present invention may be employed with any suitable container, such as rigid Regular Slotted Cartons (RSC), preferably, the handle is applied to a container in the form of a flexible bag structure 12, such as is shown in FIGS. 1, 2 and 3.
  • Such bag structures include opposing major sides 14 and 16 and preferably include opposing pleated side walls 18 (only one of which is shown in FIGS. 1 and 2).
  • the flexible bag structure is tubular and includes openings at each end that are closed by closures 20 after the bag is filled. Such closures are known in the art and will not be discussed in greater detail further herein.
  • the pleated side walls 18 enable the bags to be stored in a flat or folded arrangement, such as shown in FIG. 1, prior to receipt of the intended contents 22 (shown in FIG. 3) of the bag.
  • the contents of the bag are products with multiple discrete components that may be dispensed in a flowable state, such as dog food, cement, charcoal, or powdered substances.
  • the handle of the present invention may be employed with a bag containing any substance.
  • Bag structures may be constructed of multi-walled material. That is, the bags are constructed from multiple layers 24a, 24b, 24c, as shown in FIG. 2A, such as from a paper or cardstock material. One or more of the layers may be constructed of a polymeric material or the like, designed to act as a moisture barrier to protect the contents of the bag.
  • a commercially available flexible tubular bag structure is the package for the dog food marketed under the trademark "Kibbles and Bits" by The Quaker Oats Company of Chicago, IL.
  • the tape handle 10 comprises a first handle member 30 and a second handle member 32.
  • the first handle member 30 includes first side 34 and a second side 36 and opposing end portions 38 and 40.
  • the second handle member 32 includes a first side 42 and a second side 44 and opposing end portions 46 and 48.
  • the handle 10 is formed by adhering a portion of the second side 36 of the first handle member 30 to the side wall 18 of the bag 12. Another portion of the second side 36 of the first handle member 30 is adhered to an intermediate, and preferably a medial, portion of the second side 44 of the second handle member 32 to form a loop 50. Loop 50 is adapted for manually grasping of the first and second handle members for manipulating a container when the handle is attached thereto. Spaced portions of the second side 44 of the second handle member 32 are adhered to the opposing major sides 14 and 16 of the bag 10.
  • the handle is applied as shown, preferably over the center of gravity of the bag when filled. Generally, this point will be the midpoint of the bag. However, it will be understood that the handle of the present invention may be applied to any edge or even to a major side of a container, as is found to be convenient.
  • the bag may be formed with pleated end wall and the handle applied to the pleated end wall for manipulation of the bag in an upright orientation.
  • the first and second handle members 30 and 32 are provided in the form of pressure sensitive adhesive tape segments, wherein the respective second sides 36 and 44 of the first and second handle members include a layer of pressure sensitive adhesive (36', 44') and the opposite respective first sides 34 and 38 are non-adhesive back sides. Any tape may be employed that is found satisfactory for a particular container surface.
  • the handle 10 is relatively thin and flexible and may be applied to the wall material used to construct the bag, prior to formation of the bag, or to the formed bag 12 prior to receipt of the contents of the bag and in such a state, may be retracted in a folded position into the pleated, folded side wall 18 of the bag, as shown in FIG. 1.
  • the handle 10 is thus unobtrusive and may be quickly and conveniently applied to the empty bag, which may then be stored and handled with the handle in the unobtrusive position shown.
  • the handle 10 may be retained in the retracted position even after the bag has been filled and then, when desired, manually grasped and extended to the position shown in FIGS. 2, 3 and 7. In the extended position, the handle may be easily and quickly manually grasped through loop 50 for manipulation of the bag and its contents.
  • the first and second handle members 30 and 32 may be constructed of any color, or either may be translucent or transparent (for the purposes of this invention, both terms shall be jointly be referred to as "light transmissive").
  • the second handle member is light transmissive and the first handle member is colored or opaque so as to be visually perceptible externally of the handle.
  • the first or the second handle members may each include indicia 52, such as advertising logos or instructions for use of the handle.
  • the handle of the present invention provides improved adherence to the bag compared to conventional tape handles such as previously described.
  • This is shown in FIG. 2A, such that a force applied to the handle in direction 54 is transmitted to the end portion 46 (shown in FIGS. 1 and 2) of the second handle member 32 adhered to the major side 16 of the bag, generally in a "peel" mode approximately in direction 56.
  • a portion of the force is also transmitted to the portion of the first handle member 30 adhered to the pleated side wall 18 adjacent side 16 along direction 58 generally in a "shear" mode, which generally provides a stronger bond.
  • the first handle member thus reinforces the second handle member during use.
  • the handle of the present invention is pulled in direction 60, as shown in FIG. 2B, it will be appreciated that the force will be applied to the first handle member 30 adhered to the pleated side wall 18 adjacent side 16 along direction 62, or generally in a peel mode, and the second handle member will reinforce the first handle member with a portion of the force transmitted along direction 64, generally in a shear mode.
  • the handle is pulled in a lateral direction, one side of the handle will be stressed as described with respect to FIG. 2A and the other side of the handle will be oppositely stressed as described with respect to FIG. 2B, with both sides being self reinforced.
  • the handle of the present invention ensures that no matter how the handle is grasped or manipulated, the handle will not be adhered to the bag solely in a peel mode and the strength of adherence and security of the handle will be increased substantially.
  • the bags may be constructed with the portions of the layers adjacent and underlying the locations where the spaced portions 46, 48 of the second handle member are adhered to the outermost layer of the bag, are reciprocally adhered together (as at 66 in FIG. 3).
  • the preferred embodiment of the invention provides that the opposite end portions 38 and 40 of the first handle member 30 are overlapped adjacent an intermediate, and preferably a medial, portion of the second handle member 32 to form loop 50.
  • FIG. 5 One method for constructing the embodiment of FIG. 4A is illustrated in FIG. 5.
  • a first web 70 having an adhesive side 72 and a back side 74 is formed into a continuous tube with pressure sensitive adhesive side 72 presented outwardly and laterally spaced side edges 76 as 78 overlapped in a longitudinal direction.
  • a second web 80 having a pressure sensitive adhesive side 82 and a non-adhesive back side (not shown) is aligned with the first web 70.
  • the pressure sensitive adhesive sides 72 and 82 of the first and second webs are reciprocally adhered at an intermediate, and preferably medial, line on the second web 80.
  • a portion of the structure thus constructed is transversely severed, such as at the line 86, to form a handle 10 having a first handle member 30 and second handle member 32 of a desired width.
  • a plurality of such handles may thus be sequentially formed in a similar fashion.
  • an alternative embodiment 10a of the handle of the present invention may be constructed without overlapping the end portions of the first handle member.
  • a segment of masking or deadening material 90 may be interposed between the respective second sides 36 and 44 of the first and second handle members. If the first and second handle members are provided in the form of segments of pressure sensitive adhesive tape, then the segment of masking material may be non-adhesive. As previously described in regard to the first and second tape segments, the deadening material 90 may in a similar manner be light transmissive or opaque and may include indicia (not shown).
  • FIG. 4C illustrates yet another alternate embodiment 10b of the present invention wherein first side 34 of first handle member 30 includes a layer of adhesive 34'.
  • An intermediate, and preferably medial, portion of the first side 34 of the first handle member 30 is adhered by layer 34' to an intermediate, and preferably medial, portion of the second side 44 of the second handle member 32.
  • Spaced end portions 38,40 of the first side 34 of the first handle member on opposite sides of the portion adhered to the second handle member are adhered by layer 34' to pleated side wall 18 of the bag, and end portions 46, 48 of the second side of the second handle member 32 opposite the portion adhered to the first handle member are adhered to the major sides 14, 16 of the bag to secure the handle 10b to the bag 12 as previously described.

  • FIG. 6B shows another embodiment 10d of the handle wherein loop 50 terminates without extending over the edges of top 98 of the carton 92 (only one end of which is shown) onto sides 94 and 96 (not shown).
  • the handle is less expensive than the embodiment shown in FIG. 6A, but the abutting cover flaps (not shown in FIG. 6B) of the carton have a tendency to separate and extend upwardly when the carton is lifted.
