I was cleaning out my moms garage of my stored stuff and cam across an olive green package labeled Lightningpak. I was unable to locate any info online about this other than by the patent number 1901313. It would seem that it is some sort of heating device and by the color and design of the pack I am gussing military issue or used. It shows was made by rose derry company in newton mass. Any thoughts on date and value would be helpful.
 
Found this, seems like what you might have.

Look on page 4 of the PDF.

Almost sounds like a mutilpurpose predecessor to the MRE heater packs. The Navy used something like this to help keep deep sea divers warm underwater. This seems like it could be used as a heat compress, foot warmer, or a multitude of other things. Kinda neat.

check this out, near the bottom of the page. Not a lot of info out there though.

Google "lightningpak heating pad" and you'll come up with a few hits.

They were chemical heating pads. Apparently they were used by the military during World War II, primarily by the medical corps.

There are a number of chemicals that, when dry, release heat when exposed to water.

When the chemicals are dried out, adding water again will repeat the process.
 
Yeah, reusable chemical heat pads. I still have a couple left from when I was a medic in the late 80's so they were still around then. Pour in a little water and they stay hot for 5 or 6 hours.
