Method and system for ultrasonic sealing of food product packaging

Abstract

A method and system for ultrasonic sealing of food product packaging is provided. The ultrasonic sealing system preferably includes a food product packaging-positioning system that delivers food product packaging and food product into direct on-item-packaging forming box. The direct on-item-packaging forming box then receives the food product packaging and forms it directly around the supplied food product forming a partially packaged food product. The partially packaged food product is then ultrasonically edge sealed around the food product by an ultrasonic food product packaging fin-sealing unit forming a partially sealed food product packaging. The partially sealed food product packaging then enters a food product packaging end-sealing unit which ultrasonically seals and crimps the ends of the food product packaging resulting in a fully packaged and ultrasonically sealed food product.

What is claimed is:  
     
         1 . A system for ultrasonically end-sealing food product packaging, said system including: 
 a rotary anvil; and,    a rotating ultrasonically activated end-sealing horn operably positioned with respect to said rotary anvil, said ultrasonically activated end-sealing horn and rotary anvil operating in conjunction to ultrasonically end-seal said food product packaging passing between said ultrasonically activated end-sealing horn and rotary anvil.    
     
     
         2 . The system of  claim 1  further including said ultrasonic end-sealing horn having four edges.  
     
     
         3 . The system of  claim 1  further including said rotary anvil having four edges.  
     
     
         4 . A method for ultrasonically end-sealing food product packaging, said method including the step of: 
 end-sealing food product packaging by passing said food product packaging between an operably connected rotary anvil and an ultrasonically activated horn.    
     
     
         5 . The method of  claim 4  further including end-sealing food product packaging by passing said food product packaging between an operably connected rotary anvil and a rotating ultrasonically activated horn.  
     
     
         6 . The method of  claim 4  further including the food product packaging is continuously fed into said ultrasonic food product packaging end-sealing unit.  
     
     
         7 . The method of  claim 4  further including a confectionery food product.
