US 4787880 AAbstract
A method of making bags having a reclosable zipper between wall panels and extending between side edges at the top end of the bag, the zipper comprising a continuous length of extruded profile plastic strip folded upon itself for zipper closing interengagement of its profile parts, the profile strip portions being spot welded together at the fold in the strip which may be at one end of the side edges of the bag, such as a fold in the material which provides the walls of the bag. The strip may be notched out to facilitate folding. By differential mass, or differential spacing, or tilted biasing of profile parts of the zipper strip, and provision of a lateral flange of substantial width on the strip not only is interlocking of the profile parts facilitated, but an expedient is provided for restraining opening of the zipper by internal bag pressures, while permitting relatively easy opening of the bag from the outside, i.e. the top or mouth end of the bag. Proper orientation of the zipper strip relative to the mouth end of the bag is facilitated by differentiating the profile parts as by contrasting color.
1. A method of making a bag with an extruded plastic zipper strip attached therein and having a plurality of spaced parallel profile parts, one side of the strip being adjacent to the mouth end of the bag and the other side of the strip being at the inner side of the bag, and comprising:forming all of said profiles of generally arrow shape having arrowhead profile portions connected to a base by respective stems; folding the strip upon itself within the bag for separable interengagement of said profiles of the folded portions of the strip; and forming the profile at said other side of said strip with its stem biased toward the next adjacent profile so that in the interengaged folded strip separation of the profiles by forces from the inside of the bag will be resisted to a greater extent than forces applied for separating the profiles from the outside of the bag. 2. A method according to claim 1 which comprises providing said other side profile with a curving stem supporting a head of generally arrow shape in cross-section.
3. A method according to claim 1 which comprises forming said other side profile with a curving stem thereby effecting a tilted relation of said other side profile toward the nearest adjacent profile, and the profiles are formed substantially equally spaced from each other.
This is a division of application Ser. No. 812,467, filed 12/23/85, now abandoned.
This invention relates to the art of making bags equipped with reclosable extruded plastic zippers.
In a recent development as covered in the copending application of Christoff and Ausnit, Ser. No. 574,878, filed Jan. 30, 1984 now U.S. Pat. No. 4,617,683, and assigned to the same assignee as the present application, it has been proposed to provide zippers formed from extruded profiled continuous strips folded upon themselves so that the profiles on the folded strip portions interlock to provide reclosable zippers for the bags. In that application it has also been proposed to notch out the zipper profiles at the fold in the strip to facilitate folding of the zipper strip portions upon themselves. However, there has been some problem at the zipper fold in that memory factor of the plastic material tends to spread the fold which may cause a leakage problem at that point. Such leakage may be either of contents from within the bag, or intrusion of foreign matter including air into the bag.
It is therefore an object of the present invention to gain the advantages of the folded zipper concept and cure the open fold problem.
There is provided by the present invention a method of making a bag with an extruded plastic zipper strip attached therein and having a plurality of spaced parallel profile parts, one side of the strip being adjacent to the mouth end of the bag and the other side of the strip being at the inner side of the bag, and comprising forming all of the profiles of generally arrow shape having arrowhead profile portions connected to a base by respective stems, folding the strip upon itself within the bag for separable interengagement of the profiles of the folded portions of the strip, and forming the profile at the other side of the strip with its stem biased toward the next adjacent profile so that in the interengaged strip separation of the profiles by forces from the inside of the bag will be resisted to a greater extent than forces applied for separating the profiles from the outside of the bag.
FIG. 11 is a view similiar to FIG. 10, but showing still another modified form of the zipper strip;
A reclosable zipper 17 is sandwiched between the upper portions of the wall panels 11 and extends lengthwise between the side edges 12 and 13. The zipper 17 comprises a continuous length of extruded profiled plastic strip having a plurality of spaced parallel profile parts, in this instance comprising two parts 18 and 19. The strip is folded upon itself to provide confronting complementary portions 20, which extend from a fold 21. One of the zipper portions 20 is attached to one of the wall panels 11 and the other of the portions 20 is attached to the other of the wall portions 11. Desirably the zipper strip fold 21 is located in the folded side 12 of the bag 10. The zipper profile parts 18 and 19 are releasibly interengagable with one another for closing the top opening 15.
In an efficient arrangement, the zipper strip 17 comprises a flanged base 23 secured either by fusion or adhesively to the bag wall panels 11. From one face of the base 23 the profile parts 18 and 19 project integrally in spaced parallel relation. The profile part 18 has a curved neck 24 topped by an arrow shaped head 25. On the other hand, the profile part 19 has a curved neck 27 and an arrow shaped head 28. In order to facilitate separable interlocking interengagement of the profile parts of the folded zipper strip, the necks 24 and 27 are formed on approximately a common radius and are spaced apart sufficiently to provide a groove 29 receptive of one of the profile part heads 25 or 28 as the case may be. At their confronting sides, the heads 25 and 28 are spaced apart a distance somewhat greater than the thickness of the necks 24 and 27, but less than the overall width of either of the respective heads 25 and 28. Thereby, the respective profile part heads can engage within the groove 29 of the companion folded zipper strip portion as shown in FIGS. 6 and 7. In FIG. 6 the profile part head 28 is engaged in the groove 29 of one of the zipper strip portions 20 and the head 25 is engaged in the groove 29 of the other zipper strip portion 20. As shown in FIG. 7, just the reverse interengagement of the heads within the grooves prevails. In either event, the zipper is thoroughly closed. Both in the closing maneuver and in the separating maneuver, the necks 24 and 27 enable resilient flexing of the profile parts for the heads 25 and 28 to pass one another.
In order to provide for thorough resistance to opening of the zipper due to pressures within the bag 10, without inhibiting the opening of the bag by opening maneuver applied at the outside of the bag opening 15, the zipper profile part 18 is constructed stiffer than the part 19 by a somewhat greater mass in at least the profile head 25, and desirably also in the connecting neck 24. This stiffening of the profile rib parts 18 also facilitates interengagement of the zipper portions to assure that the profile part 18 of the folded strip always engages with itself in mutually resistive fashion relative to pressure from the inside of the bag tending to separate the zipper.
The zipper strips 17 may be economically produced in a mass production manner by extruding a plurality of the strips in a tubular extrusion 34 (FIG. 8). For example, eight of the zipper strips 17 may be produced in the one extrusion 34 and the extrusion separated along longitudinal lines 35 to divide the same into individual zipper strips 17.
Where the zippers are prefabricated and then assembled with prefabricated film or web, and one side of the zipper in each instance is equipped to provide internal bag pressure resistance as has been described, it is important that the side of the zipper which is so equipped be properly placed when attaching the zipper to the web. Such proper placement is visually determinable by ready identification or recognition of the resistance equipped side of the zipper, that is the side which is provided by the heavier section profile parts 24, 25 (FIGS. 6 and 7) and 41, 42 (FIG. 9) previously described herein.
In another arrangement as shown in FIG. 11, a zipper 55 has opposite zipper strip bases 57 which are secured to opposite wall panels 58 of a bag. Substantially wider flange portions 59 along the outer sides of the zipper strip bases 57 cooperate with the mouth end portions of the bag wall panels 58, and provide substantial pull flanges, as well as the additional advantages of facilitating attachment of the zipper to the wall panels and folding of the zipper strip on itself. In this instance there are four generally arrowshaped zipper profiles on each base strip 57, comprising three identical profiles 60 inwardly from the flange portions 59, and a fourth generally arrowshaped profile 61 at the inner side of each base strip 57. All of the profiles 60 and 61 of the zipper 55 are, in this instance, equally spaced from one another and define grooves 60a between the profiles 60 and a respective groove 61a between each of the profiles 61 and the adjacent profile 60. Greater resistance to opening due to forces from within the bag is achieved by tilting or biasing the arrowhead of each of the innermost profiles 61 toward the adjacent profile 60, by curving necks 62 of the profiles 61 toward the adjacent profile 60. Through this arrangement, when the profiles are interlocked a side flange 63 on the profile 61 in groove 61a interlocks with an adjacent side flange 64 of the nearest profile 60 close to a neck 65 of the profile 60. Thereby, forces interiorly of the bag tending to separate the zipper are resisted by the interengagement of the side flanges 63 and 64. On the other hand, the normal interengagement of the opposing head side flanges of the profiles 60 permits easier opening of the zipper at the mouth end of the bag as may be effected by manipulation of the pull flanges 59.
As shown in FIG. 14 bag making material, similar to that shown in FIG. 12, may comprise bag wall sheet material 79 of any preferred type suitable for the intended purpose and adapted to be folded along a longitudinal line 80 to provide bag wall panels 81 adapted to be folded upon themselves and sealed along the joined longitudinal edges and then severed into bag length sections from a continuous strip of the material. Along the end of the sheet 79 to form the top reclosable end of a bag, a zipper strip 82 is secured. This zipper strip 82 is of a continuous length and extends across the entire width of both of the panels 81, and when the sheet 79 is folded along the line 80, the zipper strip 82 is similarly folded upon itself along that line which extends across the zipper strip. In this instance, the zipper strip 82 comprises a base 83 carrying three generally arrowshaped profiles 84 extending therealong, and which are interlockably separably interengagable when the zipper strip is folded upon itself.
The construction in FIG. 17 is similar to the construction in FIG. 14, and therefore primed reference numerals are applied in FIG. 17 to identify substantially similar parts. As noted, a film or sheet 79' in a continuous ribbon or strip of desired width to be formed into successive bag sections is arranged to be divided longitudinally along a line 80' to provide panels 81' to be folded onto themselves and then secured together at their longitudinal edges. A zipper strip 82' having a base 83' and generally arrowshaped profiles 84' extends across the sheet 79' at the place which will provide the top or reclosable end of a bag when the material is folded upon itself, including the strip 82' wherein the profiles 84' are releasably interlockable. Along what will be the top of the bag, the strip 82' has a pull flange extension 87' which is secured by means 85' to the bag wall sections 81'. In this instance, the zipper strip 82' has an inward lateral flange extension 88 projecting in the opposite direction from the flange 87'. The flange 88 may be secured by means 89 such as heat sealing or adhesive to one of the panels 81 as shown in FIGS. 17 and 18, remain unsecured to the other of the panels 81' as shown in FIGS. 17 and 19. This serves to relieve the closed zipper from internal pressures within the ultimate bag which might tend to open the zipper from the inside. It will be observed that except for the securing means 85' and 89, the base portion of the zipper strip 82', including the flange 88, remain unattached to the sheet 79'.
