Definitions

  • the present disclosure relates to container closures including a cork material interlocked with a handle or cap (hereinafter referred to as a cap).
  • the present stopper comprises a cork portion that is bonded to a cap portion via an interlocking interface.
  • the cork material is a synthetic cork material.
  • the cork material is injection molded over a portion of the cap, which portion includes surface contouring that provides more surface area for the cork to cap bond.
  • a first cap portion contour creates a mechanical interlock that resists relative movement of the cork and the cap in a first direction.
  • a second cap portion contour creates a mechanical interlock that resists relative movement of the cork and the cap in a second direction.
  • a first cap portion contour creates a mechanical interlock that resists separation of the cork and the cap. In other exemplary embodiments, a first cap portion contour creates a mechanical interlock that resists rotation of the cork relative to the cap. In other exemplary embodiments, a first cap portion contour creates a mechanical interlock that resists separation of the cork and the cap and rotation of the cork relative to the cap.
  • FIGURE 1 is perspective view of an exemplary cap
  • FIGURE 2 is another perspective view of the exemplary cap of FIGURE 1 ;
  • FIGURE 3 is a side elevation view of the exemplary cap of FIGURE 1 ;
  • FIGURE 4 is a perspective view of an exemplary stopper.
  • the present disclosure relates to a stopper, comprising a cork portion that is bonded to a cap portion via an interlocking interface.
  • the cap includes a handle portion 14 and a cork interface portion, shown generally at 16.
  • the cork interface portion includes at least one contour that provides more surface area for the cork to cap bond.
  • the illustrated exemplary cork interface portion includes a pin contour 18, a groove contour 20 on the pin contour 18, a hole contour 22 within the pin contour 18, and a plurality of fin contours 24 within the groove contour.
  • the handle portion includes a generally flat surface 26 configured to interface with cork material in circumstances where the cork diameter exceeds the diameter of the groove contour 20.
  • the exemplary stopper includes the exemplary elements of FIGURES 1-3 with a cork material 30 bonded thereto.
  • the cork material is a synthetic cork material.
  • the cork material is injection molded over the cork interface portion.
  • the cap and cork material are co-injected during assembly.
  • sliders may be used in the mold to release such contours.
  • sliders are not necessary for molding of the cap portion (for example, with reference to the exemplary embodiment of FIGURE 2 , the material of the pin contour is arranged such that a mold would not require sliders to generate the hole contours 22).
  • a first cap portion contour creates a mechanical interlock that resists relative movement of the cork and the cap in a first direction. It is noted that each of the described contours resists relative movement of the cork and the cap in at least one direction.
  • the pin contour 18 resists bending of the cork material 30 off of its longitudinal axis.
  • the groove 20 contour further resists bending of the cork material (by incorporation of the cork material past the flat surface 26 of the handle portion into the groove 20.
  • the fin contours 24 within the groove 20 increase the bonding area between the cap and cork and resist rotation of the cork 30 about the pin contour 18.
  • the hole contours 22 resist both pulling of the cork 30 away from the bottom 26 of the cap 12 and rotation of the cork 30 about the pin contour 18.
  • various cap portion contours create a mechanical interlock that resist relative movement of the cork and the cap in at least one direction.
  • the cap interface portion may include a single or a combination of contours providing a mechanical interlock.
  • various amounts of cork e.g., widths
  • the cork covers only a portion or, e.g., all of the bottom surface of the cap handle. Accordingly, it is to be understood that the various embodiments have been described by way of illustration and not limitation.
