Zipper slider assembly with diaphragm for flexible packages

Abstract

This invention provides a slider to close a zipper profile having a diaphragm of at least one metalized laminated film sealed between the flaps of the zipper profile for sealing and making the package tamper proof and act as a barrier. The said flap has plurality of horizontal lines for the purpose of selective heat transfer and enabling one side sealing on zipper assembly, thereby preventing the zipper from sealing from inside after the pouch having said zipper assembly is filled with desired material.

I claim:  
     
         1 . A slider zipper assembly with a diaphragm for flexible packages comprising: 
 zipper profile consisting of male element and a female element,    said profile having flaps on single side,    said male element having at least a pair of notches, which are coupled to corresponding notches on female elements,    a slider to close said zipper profile    characterized in that a diaphragm of at least one metalized laminated film is sealed between said flaps to seal and make the package tamper proof and act as a barrier.    
     
     
         2 . The slider zipper assembly with diaphragm for flexible packages as claimed in  claim 1  wherein the metalized laminated film is holographed, printed or plain.  
     
     
         3 . The slider zipper assembly with diaphragm for flexible packages as claimed in  claim 1  wherein the sealing of the film to the flaps is carried out by ultrasonic or heat sealing device.  
     
     
         4 . The slider zipper assembly with diaphragm for flexible packages as claimed in  claim 1  wherein the said zipper profile and slider are made of plastic.  
     
     
         5 . The slider zipper assembly with diaphragm for flexible packages as claimed in  claim 1  wherein said flexible package is a pouch.  
     
     
         6 . The slider zipper assembly with diaphragm for flexible packages as claimed in  claim 1  wherein the flexible package is a stand up pouch with a base.  
     
     
         7 . The slider zipper assembly with diaphragm for flexible packages as claimed in  claim 6  wherein one wall of the said pouch is sealed on three sides and open towards the zipper assembly.  
     
     
         8 . The slider zipper assembly with diaphragm for flexible packages as claimed in  claim 7  wherein the said wall is sealed to one of the flaps of the zipper assembly after filling the pouch with desired material.  
     
     
         9 . The slider zipper assembly with diaphragm for flexible packages as claimed in  claim 8  wherein said flap has plurality of horizontal lines for the purpose of selective heat transfer and enabling one side sealing on zipper assembly, thereby preventing the zipper from sealing from inside after the pouch is filled with desired material.
