Film for dispenser package in the form of a pouch with a flap

Abstract

An aperture forming structure for a sealed containment and dispensing package for flowable products is provided. The structure includes a breakaway tip member of thermoformable plastic. In one embodiment a cap may be integrally formed with the aperture forming structure and may be used to protect the tip member or for reclosing the aperture. An alternative embodiment relates to a pouch, wherein a flap member portion of the pouch is folded over and sealingly attached to the body of the pouch. When the flap member portion is pulled away from the body, an outlet aperture is produced through the surface of the pouch.

1 . A sealed containment and dispensing package for flowable products comprising an aperture forming means wherein a portion of said aperture forming means is folded over to create a flap member which is sealingly attached to a portion of its own surface it covers which when the flap member is folded back it produces an outlet aperture in its surface.  
   
   
       2 . The package according to  claim 1 , wherein said aperture forming means comprises a breakaway tip member made of thermoformed plastic and is integral with such sealed containment package.  
   
   
       3 . The package according to  claim 2 , wherein said breakaway tip member is located on said flap member.  
   
   
       4 . The package according to  claim 3 , wherein the outermost surface of said breakaway tip member is sealingly attached to the portion of its own surface it covers.  
   
   
       5 . The package according to  claim 2 , wherein the aperture forming means is made independently of said sealed containment package and subsequently sealingly integrated with said sealed containment package.  
   
   
       6 . The package according to  claim 5 , where a portion of said aperture forming means includes a cap thermoformed adjacent to said breakaway tip member to fit over the base of said breakaway tip member to reclose the containment package after it has been opened by the formation of said aperture.  
   
   
       7 . The package according to  claim 1 , wherein said sealed containment package has as its aperture forming means a pre-made hole pattern in one wall of the flap member which when folded over is peelably sealed to said portion of its own surface which it covers, at least completely encircling said pre-made hole pattern.  
   
   
       8 . The package according to  claim 1 , where said sealed containment and dispensing package has as its aperture forming means a pre-made cut pattern in one wall of said flap member which when folded over is peelably sealed to said portion of its own surface which it covers, at least completely encircling said pre-made cut pattern.  
   
   
       9 . The package according to  claim 1 , where said sealed containment and dispensing package has as its aperture forming means a pre-made fault line score pattern in one wall of said flap member which when folded over is peelably sealed to said portion of its own surface which it covers, at least across entire said fault line pre-made score pattern.  
   
   
       10 . The package according to  claim 7 , where said sealed containment and dispensing package is a pouch style package.  
   
   
       11 . The package according to  claim 8 , where said sealed containment and dispensing package is a pouch style package.  
   
   
       12 . The package according to  claim 9 , where said sealed containment and dispensing package is a pouch style package.  
   
   
       13 . The package of  claim 9 , where said sealed containment and dispensing package is a tube style wherein the hinged flap member with said protrusion forming a flat topped drum shaped cap member is a flat end seal on said tube.  
   
   
       14 . The package according to  claim 9 , where said aperture forming means is made independently of such sealed containment and dispensing package for subsequently sealingly integrating it with such sealed containment and dispensing packages.  
   
   
       15 . A sealed containment and dispensing package having an aperture forming means made of thermoformed plastic comprising a pair of hinged members, one member being a flap having a protrusion forming a flat topped drum shaped cap member, the other member having a mating protrusion of similar shape to said cap member with an aperture in its flat top surrounded by a generally flat rim so located that when said flap with the drum shaped cap member is hinged over the mating protrusion with the aperture in its flat top rim meets with the flat inner surface of the cap where by virtue of a preapplied peelable adhesive to at least one of the flat surfaces meeting they are peelably sealed together completely about said aperture.
