Package and heat sealing device

Abstract

Aspects of the present invention are directed to a heat sealed packaging wherein the heat seal is along a curved surface. Additional aspects of the present invention are directed to a device for heat sealing a package on a surface that is curved along the direction of force.

What is claimed is: 
     
         1 . A device for heat sealing a package comprising:
 a support boss plate having a boss with a face with one or more cavities for receiving a package and one or more gaskets secured to the face and surrounding at least a portion of the one or more cavities, wherein the gasket and at least the portion of the face on which the one or more gaskets is secured is non-flat, and   a heater plate having a heater with a face and one or more heating flanges mateable with the one or more gaskets on the support boss, wherein the one or more heating flanges are non-flat;   wherein upon mating of the support boss with the heater and an application of a downward directional force and heat, a package may be sealed with a non-linear seal along the downward directional force.   
     
     
         2 . The device of  claim 1 , wherein the support boss plate and the heater plate further include shut height bosses for optimizing the distance between the support boss and the heater when the support boss and heater are mated. 
     
     
         3 . The device of  claim 1 , wherein the one or more gaskets has a width of between about 0.05 mm and about 0.5 mm. 
     
     
         4 . The device of  claim 1 , wherein the one or more gaskets has a width of between about 0.125 mm and about 0.25 mm. 
     
     
         5 . The device of  claim 1 , wherein the one or more heating flanges has a width of 0.05 mm and about 0.5 mm. 
     
     
         6 . The device of  claim 5 , wherein the one or more heating flanges has a width of about 0.125 mm and about 0.25 mm. 
     
     
         7 . The device of  claim 1 , wherein the support boss plate and the heater boss plate comprise multiple bosses and multiple heaters corresponding to the multiple bosses. 
     
     
         8 . The device of  claim 7 , wherein the multiple bosses are independently adjustable about the x, y, and z axis. 
     
     
         9 . A package for holding a product comprising:
 a first side having an optional first recessed area and a first perimeter edge wherein at least a portion of the first perimeter edge is curved out of plane;   a second side having a second recessed area and a second perimeter edge wherein at least a portion of the second perimeter edge is curved out of plane;   wherein the first side and the second side are heat sealed together along at least a portion of the first perimeter edge and at least a portion of the second perimeter edge to form a compartment.   
     
     
         10 . The package of  claim 9 , wherein the package is comprised of PET-G, PVC, or polystyrene. 
     
     
         11 . The package of  claim 10 , wherein the material is PET-G. 
     
     
         12 . The package of  claim 9 , further comprising a consumer product within the package. 
     
     
         13 . The package of  claim 12 , wherein the consumer product is a consumer healthcare product. 
     
     
         14 . The package of  claim 9 , wherein the first side further comprises an interior wall curved out of plane and wherein the second side further comprises an interior wall curved out of plane, wherein the interior walls are heat sealed together to form at least two compartments.
