Definitions

  • the present invention relates to moisture resistant flexible packaging closures that are printed, molded and die cut from a roll of material.
  • Flexible packaging is an ubiquitous part of our society, storing contents ranging from moist dog food to dry laundry powder.
  • An efficient flexible package resists moisture, thereby preventing dog food from undue drying out due to excessive moisture egress and laundry detergent from caking due to excessive ingress of moisture.
  • Moist towelettes in flexible packaging are often stored in an automobile glove compartment, anticipating cleaning soiled hands following a visit to a fast food drive-through or an oil check.
  • the moist towelette packaging must be designed to maintain substantial moisture resistance in spite of sweltering summer days, heat build-up in the glove compartment or freezing winter nights.
  • An important aspect of maintaining substantial moisture resistance is the package closure, typically comprising two or more hinged plastic pieces that press together to substantially seal the package. Throughout content shelf life and frequent opening and closing, the closure must effectively and repeatedly resist wear out and resultant failure to maintain substantial moisture resistance.
  • closures must be readily shape-modifiable to reflect new safety feature requirements, new consumer tastes, or new advertising promotions.
  • Another crucial issue relates to the bulk of the closure that is discarded with the package following use. With greater closure bulk there is more refuse discarded, resulting in greater negative impact on the environment.
  • Injection molded closures are manufactured without adhesive and adhesives are typically stored and applied to the closures at a distant assembly site, requiring additional costly adhesive application machinery and processes.
  • adhesives applied during assembly of injection molded closures typically require environmentally hazardous solvents and their special permits and waste disposal procedures that add to production costs.
  • injection molded closures utilize plastics that, to maintain strength, require significant bulk, with discarded packages causing significant environmental impact.
  • injection molded closures do not provide an even printing surface that is conducive to conventional printing processes.
  • product warnings or instruction are therefore almost never printed on the closures, being relegated to much less visible portions of the package.
  • a closure refers to a sealable opening and closing device that is attached to flexible packaging, including inter alia towelettes, dog food and laundry detergent; the varied package content and design requirements being well known to those familiar with the art.
  • substantially moisture resistance means adequately preventing package content moisture loss or gain such that during a projected shelf life of a package, substantial quality of the contents is maintained.
  • substantially seal refers to maintain substantial moisture resistance.
  • a method for manufacturing flexible packaging closures comprising providing a roll of material, printing a design on the roll, heating the roll, forming a three dimensional shape in the roll substantially proximate to the design, and cutting the shape.
  • printing is applied directly to the roll, prior to stamping and cutting the closure. Additionally or alternatively, printing comprises conventional rotary printing, including "flexo" and offset techniques.
  • the three dimensional shape is provided by a stamp.
  • the three dimensional shape is vacuum formed.
  • a die provides the cutting.
  • the roll is heated prior to providing the vacuum forming.
  • the method includes forming a lid and a base. Further, an integrated hinge connects the lid and the base. Optionally, the integrated hinge moveably connects the lid and the base.
  • the base includes an opening and the lid substantially seals the opening when in a closed position.
  • the lid and the base include locking edges that provide a substantial seal in the closed position.
  • the locking edges comprise edges adapted to operatively integrate.
  • the locking edges comprise a raised edge on the underside of lid which presses into a depressed edge on the base.
  • the closure includes at least one circumferential flap that adheres to the flexible package when so assembled.
  • the at least one circumferential flap has a width of at least about 1.0 millimeters.

  • the at least one circumferential flap comprises at least one circumferential portion of the closure.
  • the closure has a substantially circular cross section having a diameter of at least about 25 millimeters, about 50 millimeters, 75 millimeters, 100 millimeters or even about 125 millimeters.
