Patent number: 6299012Abstract: An aperture forming structure, which when attached to or integrally formed in dispenser packages for flowable substances allows reclosure and single or multiple uses. The aperture forming structure includes a break away tip member of thermoformable plastic. The break away tip includes a hollow protrusion from a surface. The intersection of the hollow protrusion and the surface is a fault line. Rupturing of the fault line creates an aperture from which the contents of the dispenser package may exit. A cap may be integrally formed with the aperture forming structure and detached for protecting the hollow protrusion or for closing the aperture created when the fault line is ruptured. The aperture forming structure can be made by heating a relatively stiff substantially flat thermoformable sheet of and then stretching the sheet to create a first and a second hollow protrusion in a tiered configuration. A rupture line is placed at the intersection of the first and the second protrusions.Type: GrantFiled: September 23, 1999Date of Patent: October 9, 2001Inventor: Sanford Redmond
