Abstract: A package for a medical kit and a product marrying process are provided. The package has a tray including a first compartment proximate to a first end of the tray, a second compartment proximate to a second end of the tray, and a rim surrounding the first and second compartments. A flexible cover sheet is sized to cover the first and second compartments of the tray. The cover sheet is heat-sealed to the rim during a first sealing process in which a primary seal is formed to seal the first compartment of the tray, such that access to the second compartment still remains available. The cover sheet is further heat-sealed to the rim during a second sealing process in which a secondary seal is formed along the second end of the tray such that the secondary seal complements the primary seal to seal the second compartment of the tray.

Abstract: Warming devices are described having solid organic particulates that are solid at room temperature. The contents can be heated by a variety of methods such as microwave radiation or hot liquids. The solid particles act as a reusable heat reservoir to release heat over an extended period of time or absorb ambient heat and serve a protective function.
