Definitions

  • This invention relates to improvements in plastic sliders for opening and closing reclosable fasteners on plastic bags and the like, and more particularly a foldable, preferably plastic, slider which straddles a profiled plastic reclosable fastener, and particularly suited for thermoplastic bags and the like formed by a pair of flexible plastic sheets having top edges with separable fastening means extending along the lengths of the top edges and therefore at the opening of the bag.
  • the separatable fastener means comprises reclosable interlocking rib and groove profiled formations on the respective sheets.
  • Such sliders conventionally have a separator finger carried by a complimentary structure which has a transverse inger support member from which legs depend as well as foldable side walls or wings. Means are provided to interlock the side walls or wings to the legs whereby to attach the slider to the bag and around the fastener, with the finger serving to separate the fastener as the slider is moved in one direction along the separable fastener means, whilst the legs of the slider press the rib and groove of the fastener means together to close the fastener when the slider is moved in the opposite direction.
  • the slider may be firstly moved manually, or by machine, laterally (for example vertically downwardly) over the fastener means and then manually, or by machine, subsequently closing the foldable sidewalls or wings.
  • a slider to be positioned in straddling relationship on a reclosable fastener means for a bag formed by a pair of plastic sheets having separable fastener means extending along an opening for the bag and including reclosable interlocking rib and groove profiles along the plastic sheets at said opening of the bag, wherein the slider includes a support member, in use, overlying the opening to the bag and straddling said fastening means, and also carrying a separating finger adapted, in use, to engage within and adapted to separate said fastening means when the slider is moved in one direction, and a pair of legs depending therefrom to force said fastener means into interlocking relationship when the slider is moved in the opposite direction along said fastening means, and wherein means are provided to retain said slider on said bag and beneath said fastening means to prevent said slider from being laterally removed from beneath said fastening means .
  • said slider also has at least one foldable sidewall or wing integrally hinged to a side edge of at least one leg and foldable relative to its associated leg, and means are provided to interlock said sidewall with its associated leg.
  • the means to retain said slider on said bag is part of the, or each, said hinged sidewall.
  • each said leg of the slider has a foldable sidewall associated therewith.
  • each said sidewall carries the means to retain said slider on said bag and around said fastener means .
  • Figure 1 is a perspective view of the slider in the closed position relative to a plastic bag.
  • Figure 2 is a similar perspective view of the slider prior to being closed around the fastening means of the plastic bag, and
  • FIG. 3 is a more detailed perspective view of the slider of this preferred embodiment of the invention. Best Mode for Carrying Out the Invention
  • the slider of this preferred embodiment is moulded as a one piece plastic component and this is accomplished because the foldable/pivotable sidewalls are moulded integrally wit the rest of the slider.
  • the slider could be made from a plurality of separate parts which are clipped together.
  • the slider generally indicated as 10, of this preferred embodiment of the invention includes a support member 11 to the underside of which is moulded a separating finger 12 as shown separately from the remainder of the slider in Figure 3, and may be of any of the configurations shown in the aforementioned prior art US publications, and which would normally be moulded with the remainder of the slider.
  • the support member on opposite side edges thereof has depending legs or panels 13 extending along the opposite longitudinal sides respectively with a pair lugs
  • the opposite ends of the legs or panels 13 carry respective foldable sidewalls or wings 15 hinged by integrally moulded hinges 16 to those ends of the legs or panels 13, and have concave formation 17 formed on the outer sides thereof with a multiplicity of ribs as shown to assist in finger gripping during movement of the slider during opening and closing the fastener means of the plastic bags .
  • the foldable sidewalls have laterally extending vertical walls 18 and longitudinal walls 19, the longitudinal walls 19 are provided with ledges 20 which underlie the fastener means of the plastic bag to prevent or minimise the movement of the slider from around the fastener means of the plastic bag when the slider is attached to the bag and when the sidewalls or wings are swung to a position against the remainder of the slider as shown in Figure 1.
  • the laterally extending edges 18 of the sidewalls incorporate grooves 21 approximating the size of the lugs 14 on the legs or panels 13 and ribs 22 on the insides of the formations defining the sides of the grooves such that when the lugs 14 are received within the grooves 21 the ribs engage on the sides of the legs or panels 13 to hold the sidewalls or wings in position with the ledges 20 of the sidewalls or wings preventing lateral movement of the slider off the fastener means after the slider is in position.
  • the slider In order, during manufacture, to attach the slider to an associated plastic bag, the slider is firstly moved either manually, or by a machine, longitudinally onto the fastener means of the plastic bag, or laterally over the fastener means, whereafter the sidewalls or wings are swung into position either manually or by separate mechanical means, and longitudinally of the fastener means.
  • the slider may be moved manually or by mechanical means longitudinally onto one end of the fastener means and thereafter the pivotable sidewalls or wings are closed to encapsulate the fastener means within the slider.

Abstract

L'invention concerne un curseur (10) destiné à être placé en chevauchement sur un organe de fermeture refermable d'un sac constitué d'une paire de feuilles de plastique dotées d'organes de fermeture séparables se prolongeant le long d'une ouverture et comprenant des profils de nervure et de rainure d'interverrouillage refermables le long des feuilles de plastique au niveau de ladite ouverture du sac. Ce curseur comprend un élément de support (11) qui, en cours d'utilisation, recouvre l'ouverture sur le sac et chevauche l'organe de fermeture, et qui supporte un doigt de séparation (12) conçu pour pénétrer dans l'organe de fermeture et pour séparer celui-ci lorsque le curseur se déplace dans un sens. Ledit curseur comprend en outre une paire de jambes (13) reliées à ce dernier et servant à mettre l'organe de fermeture en position d'interverrouillage lorsque le curseur se déplace dans le sens opposé le long de l'organe de fermeture. Une paire d'ailes ou de parois latérales pliables (15) sont entièrement articulées (16) sur un bord latéral de chacune des jambes et peuvent être pliées par rapport à leur jambe associée, un organe permettant d'interverrouiller les parois latérales avec leurs jambes respectives pendant que des rebords (20) situés sur les ailes ou les parois latérales pliables retiennent le curseur sur le sac et sous l'organe de fermeture en vue de l'empêcher d'être retiré latéralement du dessous de l'organe de fermeture.
