Definitions

  • the present disclosure relates to container closures using natural looking synthetic cork.
  • Such synthetic cork stopper comprises a synthetic cork bonded to a cap.
  • such synthetic cork may comprise a smooth cylindrical cork 10 having a shank 12 with a flat base portion 14 and a beveled or curved tip portion 16 .
  • the flat base portion 14 is glued (note shaded adhesive area 17 ) to a cap portion 18 (e.g., plastic or wooden) to provide a synthetic cork with a cap useable by the user to remove and re-stopper the synthetic cork.
  • the present invention comprises a composite synthetic cork, wherein the flat bottom of the synthetic cork shank includes radial contouring, such that a larger contact area is provided for glue contact to the synthetic cork.
  • radial contouring comprises a spoked design on the bottom of the cork shank.
  • a cap hole is utilized in conjunction with the synthetic cork having radial contouring, the cap hole having side walls that only permit liquid glue to flow up the side of the radial contouring.
  • the cap hole having side walls that only permit liquid glue to flow up the side of the radial contouring.
  • such configuration provides a larger contact area where the glue is holding the cork compared to traditional designs. This increases the holding force of the cork to the cap and combines the traditional tensile gluing force with an additional shear gluing force.
  • FIG. 1 is side elevation view of a traditional synthetic cork
  • FIG. 2 is a top elevation view of a synthetic cork glued to a cap portion
  • FIG. 3 is a side elevation view of an exemplary synthetic cork including a base portion having axial contours
  • FIG. 4 is a bottom elevation view of the exemplary synthetic cork of FIG. 3 ;
  • FIG. 5 is top elevation view of a first exemplary cap having a smooth gluing surface
  • FIG. 6 is a top elevation view of a second exemplary cap having contoured side walls
  • FIG. 7A is a side plan view of an exemplary cork in a pre-installed condition relative to an exemplary cap;
  • FIG. 7B is a side plan view of an exemplary cork in a post-installed condition relative to an exemplary cap;
  • FIG. 8A is a side plan view of an exemplary cork in a pre-installed condition relative to an exemplary cap.
  • FIG. 8B is a side plan view of an exemplary cork in a post-installed condition relative to an exemplary cap.
  • the present disclosure relates to an improved synthetic cork, wherein a flat bottom of the synthetic cork shank includes radial contouring, such that a larger contact area is provided for glue contact to the synthetic cork.
  • the exemplary cork includes a shank portion 22 , a base portion 24 , and a beveled or curved tip portion 26 .
  • the base portion 24 has a flat bottom 28 , and at least one radial contour 30 , which contour provides increased contact area relative to traditional smooth base portion designs.
  • such radial contouring 30 comprises a spoked design on the bottom of the cork shank.
  • FIGS. 5 and 6 illustrate exemplary caps 32 configured with a hole 34 sized to receive the base portion 24 of the synthetic cork.
  • the exemplary cap 32 of FIG. 5 shows a hole 34 having smooth sidewalls 36 .
  • the exemplary cap 32 of FIG. 6 shows a hole 34 having contoured sidewalls 38 .
  • FIGS. 7A and 7B illustrate an exemplary assembly of an exemplary cork and cap, wherein FIG. 7A illustrates the cork and cap in a pre-installed configuration and FIG. 7B illustrates the cork and cap in a post-installed configuration.
  • the cork is illustrated having radial contouring 30 .
  • the cap 32 is illustrated with a hole configured to accept the cork, the hole having smooth sidewalls 36 .
  • FIGS. 8A and 8B illustrate another exemplary assembly of an exemplary cork and cap, wherein FIG. 8A illustrates the cork and cap in a pre-installed configuration and FIG. 8B illustrates the cork and cap in a post-installed configuration.
  • the cork is illustrated having radial contouring 30 .
  • the cap 32 is illustrated with a hole configured to accept the cork, the hole having smooth sidewalls 36 .
  • at least a lower part 40 (near the base portion 24 ) of the shank portion 22 has an increased diameter relative to the cap hole 34 .
  • this lower part 40 creates a seal 42 that prevents excess adhesive from exiting the adhesive contact area 44 for the adhesive in the installed configuration (note that with regard to FIG. 7B , depending on the amount of adhesive used, it may be possible to get some excess adhesive 46 outside the edges of the cap hole 40 without such seal 42 in addition to retaining adhesive within the nominal adhesive contact area 44 ).
  • Such seal 42 not only serves to assist in adhesive retention in the nominal adhesive contact area 44 but also serves to provide a more aesthetically pleasing product.
  • caps are utilized in conjunction with the exemplary synthetic cork 20 having radial contouring 30 , the cap hole having side walls that only permit liquid glue to flow up the side of the radial contouring.
  • such configuration provides a larger contact area where the glue is holding the cork compared to traditional designs. This increases the holding force of the cork to the cap and combines the traditional tensile gluing force with an additional shear gluing force.
  • Tensile stress develops when forces acting perpendicular to the plane of a joint are distributed uniformly over the entire bonded area. Shear stress results when forces acting in the plane of the adhesive try to separate the adherents.
  • the presently described caps advantageously combine both tensile and shear holding forces.
  • the synthetic cork component may comprise any acceptable synthetic cork material, and the cork may be formed by any convenient mechanism, including such materials and mechanisms as are described in co-pending U.S. patent application Ser. No. 11/640,999, filed Dec. 19, 2006 and prior U.S. Provisional Application Serial No. 60/751,299, the entire contents of each of which are specifically incorporated herein by reference (In short, these applications describe methods of creating the random and irregular markings including molding the details directly into the surface of the stopper and extruding the synthetic material into a desired shape before passing it through forming cylinders or rollers that contain the negative of the desired surface texture, and which imprint the texture onto the material's exterior surface).
  • the radial contouring 30 of the cork base portion 24 may be molded therin or shaped via forming devices.
