Abstract

431,255. Heating by chemical action. GUTWIRTH, K., 6, Zderaz, Prague. March 15, 1935, No. 8155. [Class 64 (ii)] An envelope or container for a chemical heating composition comprises an outer cover 1 of wrapping paper with an inner envelope 2 of comparatively porous paper which is made airtight over most of its surface by an adherent covering of thin parchment paper 3. Spaces 4 are left uncovered and remain porous. The envelope is closed, or opened in order to add water to the heating composition to generate heat, by folding over the part 5.
