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. The sheet may be attached to a pouch or containment member formed from a flexible sheet which contains any flowable substance. The disclosed opening and closure concepts are especially effective when used on a tetrahedral-shaped tube. Several dispenser packages include a sealed dispensing container with an easy opening aperture forming structure entirely made from a single sheet of plastic, which is reclosable after a single use by use of an integral formation.
A sealed dispensing tube having an integral aperture forming means entirely made from a single sheet;
A reclosable aperture forming means member formed from a single sheet of thermoformable plastic film comprising a hinge member with a cap on one wing of said hinge and an aperture forming means on the opposite wing so located that when said hinge member is closed, said cap sits over and about said aperture forming means.
A flexible, squeezable sealed tubular member for containing and dispensing product made from a single sheet of thermoformable plastic film having a longitudinal seal which extends from a first end to a second end of said tubular member, a fin seal at said first end, said tubular member comprising an aperture forming means thermoformed into a wall of said squeezable sealed tubular member and a circular hollow thermoformed member inserted in the second end with the hollow portion facing away from the interior of the tube.
A container comprising an outlet hole and a reclosable aperture forming means member sealingly attached to said container above said outlet hole, said aperture forming means member formed from a single sheet of thermoformable plastic film comprising a hinge member with a cap on one wing of said hinge and an aperture forming means on the opposite wing so located that when said hinge member is closed, said cap fits over and about said aperture forming means.
A dispensing package for flowable products comprising:
A dispensing package for flowable products comprising:
A dispensing package for flowable products comprising:
A dispensing package for flowable products formed of thin, flexible material comprising an aperture forming mechanism for instantly creating a nozzle-like outlet to allow product to be squeezably dispensed in a controlled manner from the interior of the dispensing package through the outlet, wherein the dispensing package has no thermoformed breakaway members that become detached from the dispensing package upon opening of the dispensing package.
A dispensing package for flowable products formed of thin, flexible material comprising an aperture forming mechanism for instantly creating a nozzle-like outlet to allow product to be squeezably dispensed in a controlled manner from the interior of the dispensing package through the outlet, wherein the aperture forming mechanism is formed in a wall of the dispensing package.
