Definitions

  • the present invention relates to slide fasteners, and more particularly to a sealing slide fastener.
  • Such sealing slide fasteners may be liquid tight, particularly water tight to prevent ingress of water to diving suits for example.
  • Sealing fasteners have many other uses, on liquid containers for example, and in some applications a gas tight fastener is required.
  • sealing slide fasteners comprising a pair of impermeable tapes and a seal for protection against leakage between the intermeshing rows of coupling elements which are mounted on the facing edges of the respective tapes.
  • Each coupling element includes a pair of members, one on each side of the stringer tape. The members may be insert moulded with an integral connector which extends through the tape to hold the element in place.
  • Each coupling element member includes a coupling portion extending beyond the thickened sealing member, the coupling portion having a neck portion and a coupling head for engagement with the coupling members on the other tape.
  • the coupling element members define between them a slot extending longitudinally along the thickened sealing member for receiving the sealing member of the opposite tape to support the sealing member against distortion out of the plane of the tape.
  • EP-A-900532 Another example of such a fastener is shown in EP-A-900532, in which a sealing member at the edge of the stringer tape is formed with a tapered, rounded nose. When the coupling elements on the tapes are engaged the edges are urged together at the nose.
  • the present invention seeks to provide a sealing slide fastener having an improved sealing joint, and good stability in the coupling joints.
  • a sealing slide fastener comprises a pair of stringer tapes each having a tape and coupling elements along the tape, the edge of the tape being formed with a sealing material, and a coupling element straddling the edge to form an open channel, the tapes being coupled together by the coupling elements and the edge of a tape being received in the channels formed by the elements of the opposed tape, wherein compression means is provided on the channel wall to compress the tape edge received in the channel.
  • the tape edge may be compressed transverse to the plane of the tape so as to squeeze the tape edge into enhanced contact with the other tape edge.
  • a sealing slide fastener comprises a pair of impermeable tapes, a sealing member along a longitudinal edge of each of said tapes, and coupling elements mounted on the tapes, a said coupling element comprising a pair of coupling element halves mounted one on each side of a respective tape and each of said coupling halves comprising a coupling portion extending beyond said sealing member, said coupling portion comprising a neck portion and a coupling head joined with said neck portion, characterised in that at least one coupling element half of an element has a wedge shaped underside portion sloped towards the sealing member of the respective tape, such that when the coupling elements of the tapes are engaged the wedge shaped underside portion bears upon the sealing member on the opposite tape edge to compress said sealing member.
  • the tapes may be substantially impermeable to liquid or gas as necessary.
  • the sealing member preferably has a flat outer mating surface transverse to the plane of the tape, which will bear against the opposed sealing member of the other tape, and may project beyond the thickness of the tape body to form a generally T-shaped edge region.
  • the projecting portions which bound the outer mating surface are arcuate.
  • the coupling element on a tape supports the projecting portion at the edge of that tape.
  • a sealing slide fastener having a pair of tapes, each having a sealing member along a longitudinal edge portion of the tape, and a series of elements mounted on said longitudinal edge portion of each of said tapes; each of said elements comprising a pair of coupling element halves mounted one on each side of a respective tape, each coupling element half comprising a leg portion and a coupling portion extending from said leg portion and beyond said sealing member, said coupling portion comprising a neck portion extending from said leg portion and a coupling head joined with said neck portion and projecting beyond said sealing member, characterised in that the sealing member has a substantially flat outer mating surface bound by projecting portions which extend beyond the upper and lower planes of the tape body, and a said coupling element half has a wedge shaped underside portion narrowing towards the mating surface of the respective sealing member; whereby when said coupling elements of said tapes are engaged said wedge shaped underside portion of a coupling element half bears upon a projecting portion
  • wedge shaped portions are provided on both halve of a coupling element to compress the sealing member from both sides.
  • a sealing slide fastener comprises of a pair of stringer tapes 100, 200.
  • Each stringer has a tape 1a, 1b carrying coupling elements 4a, 4b which interlock to hold the tapes pressed together at confronting longitudinal edge portions 3a, 3b.
  • the coupling element 4a, 4b are removed.
  • the coupling elements will extend along the length of the tape 1a, 1b.
  • each of the tapes 1a, 1b is composed of a woven or knit web core 20.
  • the web core 20 is coated on at least one side with a layer 21 of resilient and water-resistant elastomer such as natural or synthetic rubber, such as chloroprene.
  • the elastomer layer may be extrusion moulded on the web core.
  • Layer 21 provides an impermeable barrier. It will be of a material suitable for the intended purpose of the slide fastener. Thus, if the fastener will be exposed to solvents, corrosive materials, or is to provide a gas tight seal, an appropriate coating material will be used. If a waterproof fastener is required, that is one which is resistant to ingress of water, a chloroprene material is suitable.
  • the web core 20 is preferably used, to provide strength and resistance to stretching, but tape 1a, 1b may be formed entirely of the material of layer 21.
  • the layer 21 at the edge of each tape 1a, 1b is shaped to form a T-shaped sealing member 2a, 2b with a thickness greater than that of the tape 1a, 1b proper and extending along the longitudinal edge portion 3a, 3b.
  • the bar 25 of the T-shaped sealing member 2 has a curved top surface 26 formed by a projecting portion 13a, 13b and a corresponding curved bottom surface 27 edge formed by a projecting portion 14a, 14b and a flat outwardly facing region 15a, 15b providing a sealing surface 28 lying substantially perpendicular to the plane of the stringer tape 100, 200.
  • a multiplicity of coupling elements 4a, 4b are mounted on each tape 1a, 1b along a corresponding one of the longitudinal edge portions 3a, 3b.
  • apertures 23 are formed in the body 24 of the tape, along the tape edge region 3a, 3b and spaced inwards of the sealing member 2a, 2b at the required spacing for the coupling elements 4a, 4b.
  • the coupling elements are then moulded on the tape edge as well known in the art, the through aperture 23 providing an integral connection between the element halves.
  • the coupling elements may be formed, for example, of synthetic resin by injection or extrusion moulding, or of metal by die casting for some applications. Also, the element halves may be riveted together through the tape 1a, 1b, for example.
  • each of the coupling elements 4a, 4b includes a pair of upper and lower members or halves 5a, 5b disposed one on each side of the tape 1a, 1b.
  • Each of the upper and lower halves 5a, 5b includes a leg portion 6a, 6b moulded on the body 24 of the tape 1a, 1b and connecting integrally with the leg portion 6a, 6b of the other half through the aperture 23.
  • a coupling portion 7a, 7b extends from the leg portion 6a, 6b and beyond the T-shaped sealing member 2a, 2b.
  • the coupling portion 7a, 7b has a neck 8a, 8b extending from the leg portion 6a, 6b, and a rounded coupling head 9a, 9b contiguous to and complementary in shape with the neck 8a, 8b.
  • Rounded heads 9a and 9b sit between the necks 8b and 8a respectively of adjacent elements 4b, 4a on the opposed tape ( Figure 1).
  • Each coupling element half 5a, 5b also comprises a pair of integrally moulded shoulders 19a, 19b which extend laterally from the neck 8a, 8b.
  • Shoulders 19a, 19b extend along the tape edge, behind the bar of the T shaped sealing member to provide some support to the adjacent projecting portion 13, 14 against deformation in the plane of the tape, and also against deformation out of the plane of the tape, for example when the tape is flexed along its length.
  • the head 9a, 9b of a coupling element 4a, 4b rests on the shoulders 19b, 19a of the cooperating elements 4b, 4a.
  • each coupling portion 7a of an element 4a projects beyond the sealing member 2a to form a channel 16 for receiving the sealing member 2b of the opposed stringer.
  • the inwardly facing surface 30 of each coupling portion 7a has a sloping or wedge shaped underside portion 10a which slopes inwards of the channel 16, towards the sealing surface 28 at the base of the channel.
  • the channel 16 narrows towards the sealing face 28, to provide means for compressing the sealing member 2b of the opposed tape.
  • the same arrangement is provided on the coupling portions 7b of element 4b, to receive and compress sealing member 2a.
  • the engaging pressure compresses the portions 13, 14 of the T-shaped sealing member 2 symmetrically about the plane of the tape.
  • This compression of the top edge 13 and bottom edge 14 inwards in a direction transverse to the plane of the tapes 100, 200 will deform the sealing portion 15 of the engaging T-shaped sealing member 2 on the tape 200 tending to urge the surface 28 outwards towards the surface 28 of the opposite tape to enhance the seal formed between the surfaces 15.
  • the elastomeric body of the sealing member 28 is constrained by its surrounding and so may be more dense or firmer, as well as deformed, depending on the precise geometry of the coupling elements, and the flexing of the tapes in use.
  • the coupling elements 4a, 4b are moulded to embrace the arcuate surfaces 26, 27 of the projecting portion 13a, 13b, 14a, 14b on the respective tape on which the element is mounted, to provide additional support at the edge of the tape.
  • the degree of compression or deformation required at the sealing member will depend on the particular materials used and the strength of the seal required. A high degree of compression and/or a relatively firm sealing material will require greater force when closing the slide fastener. Also, while it is presently preferred that in the uncompressed state, the sealing surface 15 will just lay on the mid line or joint line M-M of the coupling elements, it may be preferable to place it inwards or outwards of this line in some applications to provide a lesser or greater sealing force.
