Abstract

The bag comprises a closed sealed transparent envelope of flexible material. Two sachets, also transparent, hermetically sealed and of flexible material, are integral with the envelope. One sachet contains a mixt. of polyols, activators, water for generating CO2 gas to cause expansion and opt. a supplementary inflating agent such as trichlorofluoromethane. The other sachet contains an isocyanate. Rupture of the sachets releases their contents to the envelope where they are mixed, generating a polyurethane foam. [FR2416172A1]
