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.
Claims20
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.
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.
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.
