Definitions

  • the invention relates to a pair of carrying handles of flexible plastics material, preferably polyethylene, for carrier bags of no] Foreign Appncamm prlomy Dam plastics, paper or The like, in which each handle comprises a Dec. 22, I969 Germany ..P l) 64 200.6
  • each mounting strip is of substantially U section and disposed beyond the mouth when the mounting strip is so attached, the open sides of the U sections confronting one another in the finished bag.
  • the mounting strip of one handle be provided with flexible lugs which can be pulled through eyes provided in the mounting strip of the other handle for the purpose of securely closing the bag by interconnecting the handles.
  • Such handles have not proved particularly successful in practice because the closing operation is time-consuming and therefore costly and unsuitable for mass production.
  • one of the mounting strips is provided with hooks instead of eyes, holes in the other mounting strip being suspended from the hooks. In this form the closing operation takes up much less time but in many cases the amount of required manipulation is still excessive.
  • the invention aims to provide a pair of carrying handles with which unintentional opening of the carrier bag is almost impossible under the action of the weight or volume of the material with which the bag is filled, the manipulation required to interconnect the two handles being no greater than that for interconnectinghandles provided with press studs.
  • a pair of carrying handles of flexible plastics material for a carrier bag each handle comprising a mounting strip of which a first longitudinal marginal portion is attachable to a respectivewall of the bag along the mouth thereof and a second longitudinal marginal portion is of substantially U section and disposed beyond the mouth when said first portion is so attached, a hand grip portion defining a hand hole, and means for interengaging said handles with said first portions in face-to-face contact and with the openings of the U sections confronting oneanother, wherein at least along parts of the lengths of the mounting strips the respective limbs of theU sections furthest from said first marginal portions extend beyond the contacting faces of said first marginal portions so that one of these limbs overlies the other limb when the handles are interengaged, the said one limb terminates in a hook-like member received in a recess of the U section possessing the other limb when the handles are interengaged, the U section possessing said one limb is provided with a flange parallel to said one limb and
  • any downwardly and outwardly directed forces exerted on the mounting strips are unlikely to result in separation of the strips because the resultant torque applied to the mounting strips would only have the effect of pressing the said other limb against the flange and against the hook-like member of the one limb, thereby resulting in more secure interengagement of the handles.
  • the lengths of the said other limb and flange are chosen so that they abut the webs of the respective'opposite U sections, the parts of the mounting strips which bring about interengagement are prevented from moving relatively to one another.
  • the handles can be separated only by lifting the said one limb and releasing its hook-like member from the recess of the U section possessing the other limb.
  • the said other limb is readily received in the space between the said one limb and flange but insertion of the said other limb can be facilitated by chamfering its free edge.
  • a complementary bevel would then also be necessary at the transition between the web and the said other limb of the U section possessing said other limb.
  • the U section possessing said other limb may be provided with a further flange which is parallel to said other limb and terminates in a further hook-like member received in a further recess in the U section possessing said one limb when the handles are interengaged.
  • both the hook-like member and the further hook-like member are flush with the webs of the respectively opposite U sections.
  • the hand grip portions of the handles may also be advantageous for the hand grip portions of the handles to be provided with interengageable cross-sections of U shape, one limb of one hand grip portion overlapping a corresponding limb of the other hand grip portion and terminating in a hook received in a still further recess of the said other hand grip portion, the hook preferably again being flush with the web of the opposite U section.
  • FIG. 1 is a fragmentary plan view of the inside of one carrying handle, i.e. the side that would be facing the other handle of a pair of handles when attached to a carrier bag;
  • FIG. 2 is a corresponding fragmentary plan view of the inside of the other handle of the pair;
  • FIG. 3 is a section taken on the line NO in FIG. 1;
  • FIG. 4 is a section on the line J-K in FIG. 2;
  • FIG. 5 is a cross-section corresponding to FIGS. 3 and 4 but showing the handles interengaged
  • FIG. 6 is a section on the line P-Q in FIG. 1;
  • FIG. 7 is a section on the line L-M of FIG. 2;
  • FIG. 8 is a section corresponding to FIGS. 6 and 7 but when the handles are interengaged;
  • FIG. 9 is a fragmentary section through the interengaged handles and taken at a position corresponding to the line R-S in FIG. 1;
  • FIG. 10 is a view similar to FIG. 1 but of a modified embodiment
  • FIG. 11 is a view similar to FIG. 2 of a modified handle which forms a pair with the handle of FIG. 10;
  • FIG. 12 is a section on the line T-U in FIG. 10;
  • FIG. 13 is a fragmentary section on the line V-W in FIG. 11, and
  • FIG. 14 is a section on the lines T-U in FIG. 10 and V-W in FIG. 1 1 showing the handles interengaged.
  • the handles 1 and 2 constitute a pair and comprise respective mounting strips 3 and 4 of which a flat longitudinal lower marginal portion is attachable to a respective wall of a carrier bag of plastics film, paper or the like by welding, glueing, hot sealing or the like.
  • the flat lower marginal portion of each mounting strip will extend along the mouth of the bag while an upper marginal portion of substantially U section will be disposed above the mouth.
  • Each mounting strip carries an integral hand grip portion 5 or 6 which is also of U section and defines a hand hole. When attached to the bag, the openings of the U sections of the mounting strips and the hand grip portions confront one another.
  • the mounting strips 3 and 4 are provided with means for interengaging the handles so that the aforementioned flat lower marginal portions of the mounting strips will be in face-to-face contact as shown in FIG. 5.
  • the handles will normally be secured to the inner faces of the walls of the carrier bag but, should they secured to the outer faces of the walls, then the latter will be sandwiched between the fiat marginal portions of the interengaged mounting strips 3, 4 and the term face-to-face contact as used in this specification should be construed accordingly.
  • the limb 7 of the U section of the mounting strip 3 of the handle 1 is at a lower level than the limb 8 of the U section of the mounting strip 4 of the handle 2. Both of the limbs 7 and 8 extend beyond the contacting faces of the flat marginal portions of the mounting strips.
  • the limb 8 is provided at its free edge with a plurality of spaced hook-like members 9.
  • a recess 11 which extends lengthwise of the mounting strip 3 and in which the hook-like members 9 are received as shown in FIGS. 5 and 8 when the two handles are interengaged.
  • the outer faces of the members 9 are flush with the outside of the web 10,
  • the web 12 ofthe U section of the mounting strip 4 is provided with a flange 13 which extends parallel to the limb 8 and at such a spacing from the limb 8 that the limb 7 will fit therebetween.
  • the flange 13 is chamfered at its free end and, when the handles are interengaged as shown in FIGS. 5 and 8, the chamfered end will abut a correspondingly bevelled surface 14 at the transition between the limb 7 and the web 10.
  • the length of the limb 7 is such that it will abut the inside of the web 12 when the handles are interengaged. As soon as it has reached this abutting position, the hook members 9 will be engaged in the recess 11 to lock the handles in their interengaged condition.
  • the hand grip portions 5 and 6 are also of U section, the limb 15 of the portion 6 overlapping the limb 16 of the portion 5 and being provided with a hook-like member 17 received in a recess 18 of the portion 5 when the handles are interengaged.
  • FIGS. 6 to 8 in relation to FIGS. 3 to 5 that the interengaging means at the ends of the mounting strips 3 and 4 are of similar construction to the interengaging means at the middle of the mounting strips.
  • FIG. 9 shows that at those positions where there are no interengaging means the limbs 8 and 15 extend beyond the contacting faces of the flat portions of the mounting strips 3, 4 and overlap the limbs 7 and 16, respectively.
  • FIGS. 10 to 14 differs from the FIGS. 1 to 9 embodiment in the manner described hereinafter. Integers that have already been described in connection with FIGS. 1 to 9 are provided with the same reference numerals and will not be described again.
  • the U section of the mounting strip 3 is provided with flanges 19 which extend parallel to the imb 7 and terminate in hooks 20 which are similar to the hook-like members 9.
  • the web 12 of the mounting strip 4 is provided with complementary recesses 21 in which the hooks 20 are received when the handles are interengaged as shown in FIG. 14.
  • the thickness of the hooks 20 and the depth of each recess 21 are so chosen that the outer face of the hooks 20 will be flush with the outer face of the web 12 in the FIG. 14 condition.
