      Actually, I do think you're right looking at this again and the daijisen definition, it really usually refers to rubber water bottle but used for cooling rather than heating, or a plastic version of that. Maybe this works to clarify?

Or we could just go back to the original.

      but does this refer to cold compresses?
氷枕 are rubber things you sleep with

      The JEs all have "ice pillow", but I suspect they are being rather 直訳.

      Adding more natural English translations for this. Honestly not sure if "ice pillow" should be included, I don't think it's ever a common English term for this. Google images for "ice pillow" shows actual pillows with cooling technology

Also adding the ひょうちん reading
