Fig. 6 yis a similarly enlarged view on the line S--B of Fig. 3.
The bag in which the present invention is embodied and for which it is specially adapted includes two or more bags nested one within the other and each composed of a sheet of material,
such as paper, having its vertical margins overnestedl tubular" sheets b e olx passing through opposit strip," Aan'd-j all offth'e -l'eiii'ce"t has beidetcled thebag o` mit-reiioval'o lieconteiitsv',S p foratioi's- 62rniairetlrou-ghi-alli'of thefpli'sorf n sheets l, 2 andA 3 near the open end of the bagV from which the stitches 5 had been taken. After the closure devices have been detached and the contents removed from .bags that have beennlled and used, it has been found impracticable to reuse the bags because the holes 6 weakened the margins of the plies or sheets I, 2 and 3 to such an extent that other closure devices could not satisfactorily be attached to the bags having the same datum amount of contents as first enclosed by the bags. In such attempts, if the closure devices, such as the closure devices 4, were attached to the bags below the line of stitch holes 5, the capacities of the respective bags were substantially reduced and the bags could not be filled with the xsame datum amount of contents as they originally contained. If the closure devices, such as the closure devices 4, were attached to the margins of the bags upwardly beyond the stitch holes 6, another departure from datum capacity resulted, and a part of the contents of the bags might leak through said holes. The holes 6 also constituted an unsatisfactory line of Weakness along which the bags might tear. If such closure devices were attached to the margins of the bags by stitches running along or adjacent to the holes 6, `the bags were weakened because o the formation of additional stitch holes for the new line of attaching stitches, be.- -cause it was found impossible to extend the stitches through the previously formed holes 6. Then, too, in such cases, the bags did not constitute appropriate measures for determining whether they contain the same datum amount of contents as the original bags contained. The contents of the refilled bags varied too much from the required amount.
. Our present invention overcomes these diiculties and objections and provides an inelastic closure strip attached to and projecting beyond the open end of the paper bag irrespective of whether the bag had been used before or not, and functioning for the purposes of forming the bag with its original datum capacity, strengthening and reinforcing the walls of the bag around the open end and also forming an attaching device whereby the open end of the bag might be held closed to prevent loss of or access to the contents.
Fig. 1 shows a used bag from which the original closure strip had been removed to expose the line of holes 3 which extend through all of the plies or sheets I, 2 and 3 throughout their circumferential length and substantially below the Vupper ends of said plies or sheets. In Fig. 2, the
walls of the used bag have been `severed immediately below the line of stitchholes 6 to4 detach a strip from said walls and the capacity of the bag had been diminished below the datum amount to that extent. In Fig. 3, the bag of Fig. 2 is equipped with our present invention, consisting of an inelastic textile closure strip 1 secured to all of the open end margins of the plies or sheets I, 2 and 3 by aline of stitches 8.
As shown in Fig. 5, the strip 1 of inelastic textile material has its lower margin 9 folded inwardly and interposed between the outer ply I and the outer portion of the strip 1. This provides a double thickness of the ply strip 1 entirely around the bag. -Then, a line of stitches 8 is formed through the` strip 1, through the folded margin 9 of said stripand through all of the plies or sheets I. 2 and 3 entirely around the open upper end of the bag. That is, the stitches 8 leave the end of the bag open and do not pa's's through or fasten together opposed plies or sheets I, 2 and 3. The strip 1, the folded margin 9 of said strip, and the stitches 8 cooperate to reinforce and strengthen the open end of the bag, while said strip 1 extends beyond the severed end of the bag proper and constitutes an addition to or extension of the bag walls to restore the bag to its initial datum capacity.
The strip 1 extends far enough beyond the end of the bag to receive one or more lines of stitches 'for permanently closing the bag after it has been filled.
As shown in Fig. 3, the ends I0 of the strip 1 and its folded margin 9 overlap at a point disalined from the overlapping margins 0f any of the plies or sheets I, 2 and 3. The line of stitches 8 begins at a point II at the upper edge of one end portion of the strip 1, runs downwardly across the overlapping ends IU to a point I2, then continues in an approximately straight line entirely around the bag and throughout the length of the strip 'I to a point adjacent to the point I2, and then extends upwardly across the overlapped ends I0 of said strip 1 to termination at I3. Thus, the strip 1 is securely fastened to the open end of the bag and functions for all of its intended purposes.
We are aware that the strip 1 of inelastic strengthening and reinforcing material may be used initially in connection with new bags for an attaching closure device in substitution for the analog of the strip 4. Or, the strip 1 may be used to recondition, strengthen and reinforce the walls of used bags, and also to restore them to their initial datum capacity when said datum capacity has been diminished by removal of portions of the walls thereof.
We claim:
Means for restoring to an initial datum capacity a used bag composed of Walls of paper or the like and having an open end from which a strip of said walls around said open ends is detached and said initial datum capacity thereby diminished by the content capacity of said strip, for strengthening and reinforcing said walls around said open end and from which said strip is detached, and for providing a closure device for said open end of the bagcomprising a substantially inelastic strip of pliable textile material having its lower margin folded to provide a portion of double-ply thickness enclosing and contacting with the outer surface of said walls around said open end and extending beyond the ends of said walls approximately the same distance to which said detached strip extended, thereby cooperating with said walls to form a bag having the same datum capacity as the initial datum capacity of said bag before 'said iirst named strip was detached from said Walls, and a line of stitches passing through said double-ply thickness of said textile strip and through said Walls of said bag and securing said parts togethei; to form a bag having the same datum capacity as the initial datumcapacity of said bag.
