Visible light barrier for dairy packaging

Abstract

A package system having a body is described. The body has a bottom wall, at least one side wall, and a top wall cooperating with one another to define an interior compartment for housing a consumable product. At least one of the bottom wall, side wall or top wall includes a viewing portion having a light barrier configured to block wavelengths of visible light from below a baseline wavelength and above a top-line wavelength and pass visible light between the baseline wavelength and the top-line wavelength so as to allow the consumable product to be viewed through the viewing portion of the body.

What is claimed is: 
     
         1 . A package system, comprising:
 a body having a bottom wall, at least one side wall, and a top wall cooperating with one another to define an interior compartment for housing a shelf-stable consumable product, at least one of the bottom wall, side wall or top wall including a viewing portion having a light barrier configured to block wavelengths of visible light from below a baseline wavelength and above a top-line wavelength and pass visible light between the baseline wavelength and the top-line wavelength so as to allow the shelf-stable consumable product to be viewed through the viewing portion of the body wherein the baseline wavelength is in a range from 400 nm to 550 nm and wherein the top-line wavelength is in a second range from 550 nm to 700 nm.   
     
     
         2 . The package system of  claim 1 , wherein the viewing portion includes a coating layer applied to at least one of the bottom wall, side wall or top wall, wherein at least a portion of the body is formed of transparent material, and the coating layer is positioned adjacent to the transparent material and configured to allow the shelf-stable consumable product to be viewed through the body. 
     
     
         3 . The package system of  claim 2 , wherein at least a portion of the coating layer includes a texturized pattern configured to deflect light. 
     
     
         4 . The package system of  claim 1 , wherein the light barrier is an additive included during formation of the at least one of the bottom wall, side wall or top wall. 
     
     
         5 . The package system of  claim 1 , wherein the body includes an interior surface and an exterior surface, and wherein the light barrier is a textured pattern formed on at least one of the interior surface or exterior surface of the body. 
     
     
         6 . The package system of  claim 1 , wherein the shelf-stable consumable product is a dairy product. 
     
     
         7 . The package system of  claim 6 , wherein the shelf-stable consumable product includes at least one layer of yogurt, and at least one layer of a non-yogurt product. 
     
     
         8 . The package system of  claim 7 , wherein the non-yogurt product is selected from a group consisting of a fruit-based product, granola, cereal, nuts, seeds, spices and combinations thereof. 
     
     
         9 . The package system of  claim 1 , wherein the shelf-stable consumable product is a traditionally non-dairy products that can benefit from the packaged system. 
     
     
         10 . A method for making a package system, comprising:
 forming a body having a bottom wall, and one or more sidewall partially surrounding an interior compartment, at least one of the bottom wall, and one or more sidewall having a viewing portion, the viewing portion being a band-pass filter to minimize wavelengths of visible light below a baseline wavelength and above a top-line wavelength from passing through the viewing portion while allowing visible light between the baseline wavelength and the top-line wavelength to pass through the viewing portion;   disposing a shelf-stable dairy product into the interior compartment; and   sealing the interior compartment such that when the body is exposed to visible light, the shelf-stable dairy product is viewable through the viewing portion, wherein the baseline wavelength is in a first range from 400 nm to 550 nm and the top-line wavelength is in a second range from 550 nm to 700 nm.   
     
     
         11 . The method of  claim 10 , wherein the shelf-stable dairy product is yogurt. 
     
     
         12 . The method of  claim 10 , wherein the shelf-stable dairy product includes at least one layer of yogurt, and at least one layer of a non-yogurt product. 
     
     
         13 . The method of  claim 10 , wherein the shelf-stable dairy product is a traditionally non-dairy products that can benefit from the packaged system. 
     
     
         14 . The method of  claim 10 , wherein the package system is selected from a group consisting of those as claimed in any one of  claim 1  to  claim 9 . 
     
     
         15 . A method, comprising:
 obtaining a package system having a shelf-stable dairy product within an interior compartment of a body, the body having one or more sidewall partially surrounding the interior compartment and a removable layer partially surrounding the interior compartment and sealingly connected to the one or more sidewall, the sidewall having a viewing portion being a band-pass filter to minimize wavelengths of visible light below a baseline wavelength and above a top-line wavelength from passing through the viewing portion while allowing visible light between the baseline wavelength and the top-line wavelength to pass through the viewing portion, wherein the baseline wavelength is in a first range from 400 nm to 550 nm and the top-line wavelength is in a second range from 550 nm to 700 nm; and   removing the removable layer from the body to provide access to the shelf-stable dairy product.   
     
     
         16 . The method of  claim 15 , wherein the shelf-stable dairy product is yogurt. 
     
     
         17 . The method of  claim 15 , wherein the shelf-stable dairy product includes at least one layer of yogurt, and at least one layer of a non-yogurt product. 
     
     
         18 . The method of  claim 15 , wherein the shelf-stable dairy product is a traditionally non-dairy products that can benefit from the packaged system. 
     
     
         19 . The method of  claim 15 , wherein the package system is selected from a group consisting of those as claimed in any one of  claim 1  to  claim 9 . 
     
     
         20 . The method of  claim 15 , wherein the package system is made by the method selected from a group consisting of those as claimed in any one of  claim 10  to  claim 14 .
