Description
F-6137-L(PAC) Plastic Reclosable Fastener with Structure for Retain~xor Slider in Closed Position The present invention relates to a fastener struc4~re for a thermoplastic bag. The invention particularly relates to fastener structures of the type known as zippers., A conventional metal zipper has a tab on its slider. Folding dorPm the tab locks the zipper so it will not unzip. Such a featm-e has not hitherto bean provided on a plastic zipper, even though plastic zippers with sliders are well known in the art.
Plastic zippers have profiles and include a pair of male and female fastener el~errts in the form of reclosable interlocking rib and groove elf with a slider for opening and closing the rib and groove elements. In the manufacture of a thermoplastic film bag, a pair of these male and female fastener elements extend alorx3 the mouth of the bag, the male and female elements being adapted to be secured in any suitable manner to the flexible walls of the thermoplastic film bag. The elements may be 1 marginal portions of sucks walls or they may be extruded separately and thereafter attached to the walls along the mouth of the bag. A method of continuously providing such a fastener on the thermoplastic film is disclosed in US A-3462332. In US-A-3259951 there is disclosed an example of a thermoplastic bag where the fastener elements are extruded separately and thereafter attarh~i to the walls along the moaxth of the bag. This patent also discloses a slider and flexible closure strips adapted to be joined by such slider to form an airtight clue.
The sliders for opening or closing the reclosable fastea~xs are adapted to be assembled with the zipper by an endwise assembly or by a relative transverse manoeuvre. An example of a fastener with an endwise assembly of the slider is disclosed in US-A-3259951. In s instances the sliders are formed of multiple parts and assembled on the zipper. The assembly may be si~lified if the slider is formed of F-6137-L(PAC) one part and the sides are foldable into position when assembled on the zipper.
It is an object of the present invention to provide a fastener structure for a thermoplastic bag, in which the fastener structure can be aa~l closed by a slider and wherein ooaperatirig latching structure is provided to provide the feel of a secure closure when the slider has reached the closed position on the zipper.
According to one aspect of the invention there is provided a fastera~x structure for a thermoplastic bag, ccs~rising a pair of flexible plastic strips having separable fastener means extending along the length thereof o~prising r~losable interlocking male axed female profile elements on the respective strips, said male and female elements having o~nplimentary cross sectional shapes such that they are closed by pressing the elements together, a straddling slider on said strips for closing the reclosable male arx3 female el~ents, and latrhirxg means for retaining said slider in closed position when said slider reaches the closed end of its travel along said plastic strips, said latchiryg means ccm~rising a ooopexatirig detent structure on said slider and at least one of said plastic strips, said detent structure being spaced from said male and female interloc7ti.ng elements and beaaxg ettgageable when said slider is at the closed end of its travel on said plastic strips.

Acc~rdirag to another aspect of the irnrention there is provided a thermoplastic bag prising a pair of facing sidewalk defining an open mouth at one end of the bag, and a fastener structure as described above disp~ed along the mouth for c~ening and closing said mouth.
Reference is naa made to the aco~panying drawings, in which:
Fig. 1 is a fractional perspective view of a plastic bag with a fastener structure according to the present invention;
Fig. 2 is an elevational view of the fastener structure shown in Fig.
1; and Fig. 3 is a sectional view taken along the lines 3-3 in Fig. 2.
Referring to Fig. 1, there is illustrated fastener structure comprising a plastic slider 10 and a profiled plastic reclosable fastener 11. The slider 10 and fastener 11 are particularly suited for thermoplastic bags and the like and the slider l0 has been illustrated in Figs. 1 and 2 assembled on the fastener 11 at the top edge or mouth of a thermoplastic bag B. The bag B may be made frcan any suitable thermoplastic film such for example as polyethylene or polypropyler~
or equivalent material.
The bag B is formed by a pair of flexible plastic sheets 12 and 13 joined at the botto;n and having a top edge, with a pair of flexible plastic strips 14 and 15 having separable plastic means extending along the length thereof prising reclcsable interlocking male and female profile elements zn the form of rib and groove elements 16 and 17 on the respective strips to form the fastener 11. The strips 14 and 15 may be extruded separately and attached to the respective sides of the bag mouth or the strips 14 and 15 may be extruded airtegral with the sides of the bag myth. The strips 14 and 15 incl~ie profiled tracks 18 and 19 extending along the length thereof para11e1 to the rib and groove elements 16 and 17 and the rob and groove el~er~ts, 16, F-6137-L(PAC) 17 have cxettplementary cross-sectional shapes such that they are closed by pressing the elements together with the slider 10.
The Gross-sectional shapes of the intexlockir~g male and female elements having the rib and groove profiles 16 and 17 may be of any type but preferably are of the type disclosed in Wm-91/13564.
As may be seen in Fig. 1 the slider 10 straddles the fastener 11 at the top of the bag B and is adapted for opening ar closing the reclosable fastener element 16 or 17 of the fastener 11. The slider 10 is formed from a single piece of moulded plastic c~prising a separator finger 9, Fig. 2, and interlocking ocmiplementary structure moving along the fastennx 11. The slider 10 may be moulded from any suitable plastic such for example as nylon, polypropylene, polystyrene, Delrin or ABS.
In the preferred embodiment the ccmiplementary structure comprises an inverted U-shaped member includi~ a transverse supported member or body 20 fr~n which the separator finger 9 depends. The body 20 is itself U-shaped and includes two integral spac~l d 1 ependiryg egs 20a and 20b (not shown). the finger 9 is positioned betw~n the legs 20a, 20b. The body 20 is adapted to move along the top edges of the tacks 18 and 19 with the legs 20a, 20b straddling these elements and the finger 9 positioned betw~n the tracks 18 and 19. The body 20 also includes a pair of hinged °°wings°° or side walls 21 or 22 that can he folded down into their final position.
The wings 21 and 22 are hinged to the main slider body 20 by means of hinge structure located at the opposite ends of the legs 20a and 20b.
The wings 21 and 22 have central openings into which the legs 20a, 20b esctend arxi the wings 21 and 22 are folded down into their final position as shown in Fig. 1. When the sidewalk 21 and 22 are in the folded position as shoam in Fig. 1 a compression-type latGhirr~
m~hanism (not shoran) locks the sidewalls 21 and 22 in folded position with the depending legs 20a and 20b. In this assembled position, the shoulders 21c and 22c on the sidewalls 21 and 22 are positioned F-6137-L(PAC) beneath the bottcan of the fastener elements 16 and 17 to prevent the slider 10 from being lifted off the fastener 11. The foldable depPxxling sidewalk 21 and 22 extend from an opening end l0a of the slider 10 to a closing end lOb.
The sidewalk 21 and 22 and the depending legs 20a and 20b are spaced wider apart at the ~ end l0a of the slider 10 to permit the separation of the rib aryl groove elements 16 and 17 by the finger 9 engaging the tracks 18 and 19 arxi are spaced sufficiently close together at the closing end 10b of the slider to press the rib and groove elements 16 and 17 into interlocking relationship as the slider is mov~l in a fastener closing direction from the position in Fig.
1 to the closed position in Fig. 2.
As may be seen in Figs. 1-3 the extruded stxips 14 and 15 have been provided with protrusions 14p and 15p which exterr3 outwardly fr~n the surface of the strips 14 and 15. The protrusions 14p and 15p are shaped to be received within the corresponotches or indentations 21n and 22n formed in the lacer portions of the sidewalls 21 and 22 of the slider 10. As may be seen in Figs. 1 arr3 3 the notches 21n and 22n are formed in the oppose vertical surfaces of the shoulders 21c and 22c.
The ends of the notches 21n and 22n are flared at the opening end 10a of the slider 10, Fig. 3, to provide a funnel shaped caning to permit the protrusions 14p and 15p to enter the notches 21n and 22n as the slider 10 moves to the closed end of the fastener 11, Figs. 2 and 3.
The protrusions 14p and 15p are spaced with respect to the closed end of the fastener 11 so that when the slider 10 reaches the end of its travel on the fastener 11 in the closir~g direction, the protrusions 14p and 15p will be received in the notches or ~tior~s 21n and 22n. This gives the user of the bag assurance that the bag is closed with certainty. If the fastener 11 is not provided with end stops the cooperating protrusions and notches will serve to keep the slider frc~n going past the closed end of the fastener and caning off of the bag.

F-6137--L (PAC) The apposite ends of the fastexier 12 may be p~rov~id~ with end stc~s 30 formed frc~n the material at the bite ends of the faster~x 11 and pratnxde frcan the fastener a distance adequate to engage the slider 10 to prevent the slider frcera going past the respective ends of the fastener and c~i.ng off of the bag. When the fastener 11 is provided with end stops 30 the protrusions 14p and 15p are spaced with r to the closed end stc~ 30 of the fastener 11 so that rahen the slider reaches the end of its travel on the fastener 11 in the closing direction, the protrusions 14p and 15p will be received in the notches or indentations 21n or 22n.
While one type of cooperating detent structure has been described and illustrated in respect to the slider and the plastic strips, it is to be understood that other cooperating detent structure may be utilised for performing the same function, namely providing the user of the bag with the feel of a secure closure. The protrusions and indentations disclherein for providing the cooperating detent structure may be positioned at other locations than those shoran.
