ABSTRACT:
A plastic vessel (10) for containing a hot liquid and having the capability of being placed on a hot plate, burner or the like to maintain the liquid hot includes a top portion (11) molded of a first heat resistant plastic material. A base portion (13) molded of a second plastic material being more heat resistant than the first plastic material is attached to the top portion (11) to close the same and form the container for the hot liquid. One form of attachment of the base portion (13) to the top portion (11) is the utilization of a gasket (12) preferably formulated of a mixture of the first and second plastic materials which is heated to fuse the top portion (11) to the base portion (13). A heat shield (14, 40), formed of a third plastic material which is more heat resistant than the first and second plastic materials and which can withstand the heat of direct contact with the hot plate, is attached to the bottom of the base portion (13). One form of such attachment is a heat stake (32) which depends from the bottom of the base portion (13) and extends through an aperture (33) in the heat shield (14, 40) for attachment by a staking process.
