Definitions

  • FIG. 1 A first figure.
  • the disclosure relates to a reusable plastic bag, and, in particular, a hook and closure means for such a bag.
  • the hook and closure means is of the two-element type, having each element heat sealed to an opposing wall of the bag mouth and with fastening or locking means on the adjacent faces of the two elements to permit sealing of the mouth of the bag.
  • the two element handle and closure means is formed as an integral unit with the two elements lying in the same plane, but the handle and closure means is so formed as to permit a folding over of the longitudinal strip so as to bring the two elements into a mating relationship and thereby forming a unitary handle for insertion into the bag mouth.
  • thermoplastic material such as the more common vinyl or poly ethylene plastics.
  • the prior art further teaches the use of a combination handle and closure means for such a thin-film plastic bag which is sealed or cemented or otherwise fastened to the thin film.
  • the handle and closure means from thermoplastic material having a substantially heavier gage than that of the thin film used for the main portion of the bag since this provides greater strength and provides :adesirable rigidity to the mouth of the bag, thereby making it more convenient to open the bag and to maintain it open for obtaining access to the bags interior.
  • a combination handle and closure means which consists essentially of two generally congruent strips of a semi-rigid material such as a heavy gage plastic which are welded or heat sealed to the mouth of the bag. To open the bag, it is then only necessary to grasp the two handle portions with ones right and left hands, respectively, and separate the two handle portions.
  • a securing or locking means is employed which tends to hold the two oppositely disposed handle portions together, thereby effectively maintaining a tight closure of the mouth of the bag.
  • a fastening means may comprise a small protuberance on one member which frictionally engages an indentation or recess in the opposite member as, for
  • a plastic bag or container whose main body or bag portion is formed of a thin film of thermoplastic material having front and rear bag walls, together with a combination closure and handle means which comprise a unitary element rather than the two piece element used heretofore.
  • the unitary element is preferably formed of a thermoplastic material but is considerably heavier in gage than that used to form the main bag portions so that the unitary element has a very much higher tensile strength than the bag walls.
  • a unitary handle and closure means formed so as to comprise two substantially congruent strips each having a length substantially equalling the width of the front and rear bag walls at the mouth of said bag.
  • the two strips normally overlie each other and are joined at their extreme ends by means which is integral with both the strips, and holds the strips closely adjacent each other and parallel to each other at their ends. Because of the parallel relationship of the ends of the strips and because of the resilience of the material which forms the unitary closure means, any attempt to open the mouth of the bag by separating the two strips at their midportions results in curvature of the strips over substantially their entire length, but with substantially less curvature taking place near the ends.
  • each strip is quite tightly held at its end portion and deflection forces are applied to it at a point remote from the end; with such construction, there is substantial deflection over the length of the member but a minimal amount at the anchored end.
  • FIGURE 1 is a side view of the handle and closure means of the present invention
  • FIGURE 2 is a cross-sectional view of FIGURE 1 taken along the section line 22;
  • FIGURE 3 is a cross-sectional view of FIGURE 1 taken alon the section line 3-3;
  • FIGURE 4 is a view illustrating the folded-over handle and closure means of FIGURE 1 inserted into and heat sealed to the mouth of a bag;
  • FIGURE 5 is a cross-sectional view of FIGURE 4 taken along section 55.
  • FIGURE 1 shows the handle and closure means of the present invention in the form in Which it is molded by the die members.
  • the handle and closure means is shown as comprising two co-planar longitudinal strip portions 1 and 2 which are actually molded as a single sheet of thermoplastic material of suitable thickness to form handle members.
  • Extending laterally from the upper strip portion 1 along its center portion is a hook member 3 which is integrally formed with strip 1 and defines a central aperture 5 for securing the strip portion 1 to a rod or the like for display purposes.
  • a similar hook member 5 is disposed laterally of the longitudinal strip to and similarly defines a central aperture 5.
  • the entry portion of the aperture 5 is somewhat narrower than the interior portion of the aperture to provide a frictional restraint when the hook is applied to or moved from a display rod.
  • the integrally molded handle and closure means of the present invention is provided on the upper longitudinal strip portion 1 with longitudinal protruding members 7 which define therebetween a longitudinal recess 8.
  • This recess is adapted to receive a longitudinally extending protuberance 9 which extends outwardly from the longitudinal strip portion 2.
  • the end portion of the handle and closure means is provided with a thinner portion at its center as shown at 6 in both FIGURES l and 2, and this is done to more readily permit the folding together of the two strip portions 1 and 2 to form a handle and closure means which is suitable for insertion and heat welding to the edges of the bag walls at the open mouth thereof.
  • FIGURE 3 illustrates the slot 11 which is formed along the center section of the member comprising steps 1 and 2 and over substantially the entire length thereof except for the immediate thinner end portion 6 as is best illustrated in the cross-sectional view of FIGURE 2.
  • the longitudinal slot 11 corporates with the thinner section of material at 6 (FIGURE 2) to permit ready folding of the two strip portions 1 and 2 toward each other to form the integral handle and closure means.
  • FIGURE 4 illustrates the handle and closure means of FIGURES 1, 2 and 3 but with the two elements thereof folded together and inserted and heat sealed to the mouth of a bag having opposing bag walls as indicated by 12 and 13 in FIGURES 4 and 5.
  • the heat sealing of the bag walls to each of the longitudinal strips 1 and 2 is indicated at 10 in FIGURES 4 and 5.
  • FIGURE 5 also shows the locking together of the two strip portions 1 and 2 by means of engagement of the longitudinal protuberances 9 within the recess 8.
  • FIGURE 5 additionally shows the two hook portions 3 and 4 which extended upwardly and overlie each other to form, in effect, a single hook adapted for securing the bag to rod or the like.
  • the mouth of the bag can readily be opened by prizing apart the two hook portions 3 and 4. Even though considerable force may be applied to separate the hook portions 3 and 4 and thus also the longitudinal strips 1 and 2, substantially no forces will be applied to the thin-film bag walls, instead, such forces will instead be applied to the portions 6 which interconnect strips 1 and 2 at each end.
  • a bag having front and back walls formed of a thin-film thermoplastic material the improvement which comprises: unitary closure means attached to the walls of the bag in the plane of said walls at the mouth of said bag; said closure means being formed of a resilient, elastic, non-brittle material having a tensile strength substantially greater than that of the walls of said bag; said closure means being formed from a generally plane sheet of thermoplastic material and comprising an elongate strip portion having a length substantially equalling the width of the mouth of the bag, means extending laterally of each side of said elongate strip and generally symmetrically disposed relative to the mid-point of said side to form a carrying means, an elongate through-slot running longitudinally of said elongate strip portion along the mid-section thereof but terminating inwardly of each end of said elongate portion, said elongate portion being adapted to be folded over on itself along said through slot to provide thereby two overlying elongate strips for heat sealing to a respective bag wall at its month, said two carrying
  • each said laterally extending carrying means is in the form of a hook.
  • both said overlying elongate strip portions have on their respective mating faces a releasable fastening means for securing together said elongate strip portions to selectively close the mouth of said bag.
