Definitions

  • closures of this character which, while being easily opened when desired, are strong closures, adapted to withstand strains resulting from dropping or other rough handling of the bags; the provision of closures of this character adapted for unraveling of the entire line of stitching in one piece with assurance that there will not be any thread particles that may contaminate the contents of the bag; and the provision of closures .of this character which are economicaLin respect to manufacture.
  • Fig. 1 is a view in elevation of one end ing a closure of this invention
  • V Fig. 2 ' is; an enlarged plan View of the upper right corner of the bag shownin Fig. 1;
  • Fig, 3 is a view in elevation of the upper right corner of the bag shown in Fig. 1, illustrating the initial step of a bag havin the opening of the bag;
  • Fig. 4 is a view similar to Fig. 1 illustrating a modification
  • Fig. 5 is a view in elevation of the upper right corner of the bag shown in Fig. 4 illustrating the initial step, in
  • Fig. 9 is a view corresponding to Fig.7 showing the unraveling of the thread.
  • a multiwall paper bag having an end closure of this invention is indicated at 1.
  • the bag is shown as a twoatent 2,978,16 Patented Apr. 4, 1961 is applied along its side margins in narrow strips.
  • line of stitching indicated at 11 is driven through the tape and through the walls of the bag securing together the walls adjacent the end of the bag.
  • the line of stitching is located outward of the stripes of paste.
  • the length of the tape 9 is greater than the width of the bag, and the tape has end portions 13 and 15 which extend past the side edges of the bag.
  • the stitching 11 extends completely throughout the length of the tape and, "as shown, may be driven through a narrowpaper ribbon 17 constituting a so-called filler cord located on the side of the bag which is referred to as the needle side, this side being the side which faced the needle of the sewing machine employed for stitching.
  • the stitching at 11 is of a single thread readily unravelable chain stitch type.
  • the single thread used for this stitching is designated 19.
  • the stitching is formed by feeding the bag with the tape 9 folded around the end of the bag through a sewing machine having a needle which drives loops 21 of the thread 19 through the bag, thereby forming needle holes 23 in the bag, the loops extending from the needle side of the tape 9 through the needle holes to the other side of the tape, each loop being laid over on the said other side and extending through the preceding loop 21.
  • the end portion 15 of the tape which projects from the right side edge of the bag is folded back on the bag, and the folded-back end portionlS is rcleasably secured to the bag by means of adhesive as indicated at 25.
  • This folding is on a fold-line 27 which extends generally parallel to the side edge of the 'bag and which is located somewhat outward from the side edge of the bag.
  • the end portion 15 is folded over on theneedle side of the bag.
  • the adhesive is located at the very end of the end portion 15- of the tape so that the end stitch, which is specially designated 29, is anchored to the bag.
  • the width of the adhesive is less than the width of the end portion 15 of the tape so that at least one corner of the end portion (such as the corner indicated at 31 in Fig. 1) is free of the bag so that it may be grasped between the thumb and the forefinger to pull or rip the end portion 15 away from the bag.
  • the adhesive at 25 does notextend throughout the entire length of the folded-over end portion 15, and part of end portion 15 from fold 27 to the adhesive 25 is free of the bag.
  • a corner such as the corner 31 of the end'portion 15 of the tape is grasped between the thumb and forefinger, and portion 15 pulled or ripped away from the. bag so that it extends laterally outward free of the bag as illustrated in Fig. 3. Since the adhesive 25 contacts the thread and anchors the end stitch 29 and the end of the filler cord 17 to the bag, the end portion 15 of the tape pulls away from those stitches which were initially driven through end portion 15 and away from the end portion of the filler cord 17. The end of the thread and the end of the filler cord 17 remain adhered to the bag, and the stitches which pulled out of the end portion 15 appear as loops such as indicated at 33 in Fig. 3 extending out from the filler cord 17.
  • the thread will readily pull out of the adhesive 25 and then may be quickly unraveled and pulled out of the bag as one continuous length of thread without any possibility of loose bits or pieces of thread contaminating the contents of the bag, as is desirable for certain products, in particular food products for human consumption and animal feed. It will be understood that suitableinstructions as to the pulling of the end of the tape and the pulling of the end of the thread may be printed on the bag.
  • the adhesive may be spaced somewhat back from the end of the folded-over end portion of the tape, as long as it is located at a point from which unraveling of the thread may be started, but this is not as desirable as locating the adhesive at the very end because of the possibility of pinching of the end stitch between the thumb and forefinger.
  • Fig. 4 illustrates a modification which is in all respects the same as that of Figs. 1 and 2 except that the end portion 15 of the tape, instead of being folded back on a line parallel to the side of the bag, is folded back on a line 36 angled outward at a 45 angle in the direction away from the end of the bag.
  • Fig. 5 illustrates the end portion 15 of the tape of the Fig. 4 bag as it appears when pulled free of the bag and made to extend laterally outward.
  • Figs. 7 and 8 illustrate another form of the invention in which the end portion 15 of the tape 9 is not folded back, being left to extend laterally outward from the side edge of the bag.
  • a pull tab 35 is releasably secured to the end portion 15 of the tape over the thread 19 on the needle side of the tape by adhesive at 37.
  • the tab 35 consists of a strip of paper narrower than the folded tape 9. It extends beyond the end of the end portion 15 of the tape, so as to provide the projecting end portion 39 for easy grasping.
  • the adhesive extends from the inner end 41 of the tab all the way to the end of the tape. This anchors the thread against unraveling until is is desired to open the bag.
  • a bag having at least one end closure constituted by a line of stitching driven through the walls of the bag and securing together the walls adjacent said end of the bag, the stitching being of a single thread readily unravelable chain stitch type which is unravelable by pulling the thread from one end of the stitching, and means releasably secured to the bag over said one end of the stitching by adhesive and adapted to be grasped and pulled away from the bag, said adhesive contacting the thread at a point from which unraveling of the thread may be started and anchoring the thread against unraveling until it is desired to open the bag, and whereby,.upon grasping and pulling said means away from the bag, unraveling of the thread is started.
  • a bag having at .least one end closure constituted by a line of stitching driven through the walls of the bag and securing together the walls adjacent said end of the bag, the stitching being of a single thread readily unravelablechain stitch type which has loops extending from one side of the bag through needle holes to the other side of the bag, each loop being laid over on the said other side of the bag and extending through an adjacent loop, said thread being readily unravelable by pulling it from one end of the stitching, and means releasably secured to the bag over said one endof the stitching by adhesive and adapted to be grasped and pulled away from the bag, said adhesive contacting a portion of the thread lying on said one side of the bag at a point from which unraveling of the thread may be started and anchoring the thread against unraveling until it is desired to open the bag, and whereby, upon grasping and pulling said means away from the bag, unraveling of the thread is started.
  • a bag having at least one end closure constituted by a tape folded around the respective end of the bag, a line of stitching'driven through the tape and through the walls of the bag and securing together the walls ad jacent said end of the bag, the length of said tape being greater than the width of the bag and end portions of the tape extending past the side edges of the bag, the stitching extending completely throughout the length of the tape, the stitching being of a single-thread readily unravelable chain stitch type which is unravelable by pulling the thread from one end of the stitching, the end portion of the tape which includes said one end of the stitching and which projects from the adjacent side edge of the bag being folded back on the bag and releasably secured to the bag by adhesive, said ad-hesve being so located as to secure the thread to the bag at a point from which unraveling of the thread may be started and anchoring the thread against unraveling until it is desired to openthe bag, and whereby, upon grasping the end of the folded-over end portion of the tape and pulling it away from
