A conductive warmer for flexible plastic bags containing foam precursor chemicals includes a heat-conducting member of thermally conductive material having a plurality of fins which are parallel and spaced apart to define a plurality of spaced-apart bag-receiving compartments. The fins are connected to a back portion of the heat-conducting member, to which a heating element is attached in heat-exchanging relationship. Operation of the heating element conducts heat through the back portion and the fins of the heat-conducting member to the bags. The heat-conducting member is contained within a housing having an opening providing access to the open side of the compartments. The housing preferably is formed in two portions, a first portion containing the heat-conducting member and a second portion supporting the first portion, the first and second portions being pivotally interconnected to allow selective variation of the angular orientation of the first portion with respect to the second portion.

[ What is claimed is:] [1.] A warmer for bags containing a foamable composition, and comprising:a heat-conducting member having a plurality of spaced-apart compartments for receiving bags, the heat-conducting member including an integral one-piece back portion having opposite ends and having a first surface forming bottoms of the compartments, the heat-conducting member further including a plurality of spaced-apart heat-conducting fins projecting from the first surface thereof, the compartments being defined between adjacent pairs of the fins with each compartment extending along a length of the back portion substantially from one end to the other end thereof; andan electrical resistance heating element attached directly to a second surface of the back portion on an opposite side thereof from the first surface, the heating element being in heat-exchanging relationship with the back portion of the heat-conducting member for heating the back portion such that heat is then conducted through the fins to the bags.
