<p>For assembling a planar heating element to a glass bodied vessel, the heating element forming the bottom of the vessel, the heating element (or a carrier therefor) is formed with an upwardly extending flange which extends, with spacing, around the rim of a necked-in part of the lower end of the vessel body and a sealing ring is interposed between the flange and the vessel body. The heating element is supported by a base part of the vessel which is attached to the glass body part by virtue of being attached to a separate handle which extends up the side of the glass body of the vessel and hooks over its top edge. Other means of securing the base to the glass vessel body are described including a base-to-spout attachment, the provision of a band encircling the vessel body and attached to the handle which in turn is attached to the base, and adhesive. The problem of dimensional variations in mass produced blow moulded glass vessel bodies is overcome since the seal takes up any dimensional variations.</p> |
