What is inside heat pack?

My noismaker died after 2 days, is there anywhere i can get a replacement?

Does anyone know how to get the battery compartment open? The screw just turns and turns and it won't open.

Won't work when i put batteries in. it does the initial put noise to let you know the batteries are in. but then nothing helps when i press the button
