    A reclosable extruded plastic fastener for joining sheet material such as walls of bags, and method of making the same. The fastener comprises a grooved female profile and a complementary hook-headed male profile, and a stabilizing structure especially advantageous when pressing the profiles together into closed fastener assembly. The female profile has a generally square base with at least one stop shoulder to minimize tipping of the female profile about a thin, thermal bridge minimizing, heat transfer limiting stem. The hooked jaw arms of the female profile may have various geometric shapes. The male profile has an interhooking barb which interengages with the hooked jaws of the female profile. Stabilizing ribs are spaced from the head, but the rib at the inner side of the head is closer to the head than at the other or outer side, so that there is a desirable differential fastener separating relationship retaining the fastener efficiently with greater hold against opening due to internal bag forces.

    The invention relates to devices for joining two plastics of assisted sheets, in particular plastic bag walls or locking tapes
    The purpose of the invention is to improve the convenience of manufacture and use.
    FIG. 1 shows a plastic bag extruded in one piece with a device for joining two plastic sheets, cross section; in fig. 2 shows a device for joining two plastic sheets in FIG. 3 - the same version.
    A device for joining two plastic sheets (in Fig. 1, these sheets are the walls of the bag) contains 1 covering and covering 2 profiles. Each of them is in one piece with the corresponding sheet 3,4 (bag wall) and serves to permanently connect the sheets by means of an elastic snapping of the profiles one into another.
    The covering profile 2 has a bottom 5 connected to the sheet 4 and side walls 6 with inward-curved ends 7 directed toward the bottom 5. The covered profile 1 is made in the form of a head connected to the sheet using a leg 8 with lateral projections 9 to interact with the curved inside ends 7 of the covering profile 2. The bottom 5 of the covering profile 2 is connected to sheet 4 by a connecting rod 10. The thickness of the rod 10 is at least 4 times less than the width of the bottom 5 of the covering profile. The bottom 5 from the outside along the edges has a hanger 1I adjacent to the sheet 4 with the formation of a gap. The size of the gap does not exceed the height of the connecting rod 10. The bottom 5 of the covering profile can be made flat parallel to the plane of the sheet (see Fig. 2). The length of the connecting collar 10 may be greater than the gap between the shoulders 11 of the bottom 5 and the sheet (FIG. 3). In a preferred embodiment, the connecting rod 10 is located in the center of the bottom 5 of the female profile.
    On either side of leg 8 of male profile 1, sheet 3 can be made on sheet 3.

    12 and 13, one of which is located closer to the leg than the other.
    Preferably, one of
    the protrusions of the head were larger than the other, and placed on the same side as the closer tide guide 12.
    When using the device for
    The Q connection of two plastic sheets in bags is advisable so that the guiding tide 12, closer to the leg 8 of the male profile, is placed on the wall of the bag closer to
    5 to its base 14 than the second directing tide 13.
    During operation of the device, the head of the male profile is introduced into the space of the female profile, limited by the bottom and side walls. After an elastic latching of one profile in another, the head of the embraced profile remains inside the enclosing profile, interacting with its projections with the inside-curved ends of the side walls of the enclosing profile.
    Due to the connection of the bottom 5 of the enclosing profile with the corresponding sheet 4 thinner, the connecting rod 10 is hampered by heat transfer. between the cover profile 1 and sheet 4, which means that during production (extrusion) the covering profile can be cooled quite intensively without excessive cooling of the sheet. The thinning of the connecting rod limits the ability of the sheet material to flow to the profile during the manufacture of the device. This embodiment also makes it possible to combine thin sheets with sufficiently large enveloping profiles, which is convenient in
    g operation.
    The presence of hangers -11 on the bottom 5 allows, despite the fineness of the connecting rod 10, to provide the covering profile 2 with good stability. These hangers serve as stops when turning the bottom.
    The tide guides 12 and 13 make it easier to insert the male profile into the covering, making 5 sheet harder near the leg 8. These tides 12 and 13 greatly expand the support area when the device clicks into place.
