Embodiment Construction

[0018] First with reference to the exploded view of Fig. 2, it is shown in the figure that the model blow molding of the opening is generally a cylindrical glass container main body 1, an integral pouring outlet 2 is housed on its upper edge 3, and on its other One end (bottom end) is provided with a reduced diameter neck portion 4 . An O-shaped elastomeric seal 5, shown more clearly in the several views of FIG. 1 and described in more detail hereinafter, is adapted to seal with the outer surface 6 of the necked portion 4 of the container body 1. join. The seal 5 is also adapted to forcibly engage with the upwardly bent flange part 7 of the schematically shown plate heating element 8 and to seal the flange part when the heating element 8 is fitted to the base of the vessel body 1 as described hereinafter. The gap between the inner surface of 7 and the outer surface 6 of the necked body part 4. Finally, Fig. 2 also shows a base 9 provided with internal ribs 10 for maintaining...

Abstract

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.

Description

technical field [0001] The present invention relates to the improvement of electric heating containers, in particular electric heating water containers, such as kettles, thermos bottles, jars, pans, vats, experimental equipment and the like. Background technique [0002] Our UK patent application 9821862.1 relates to the incorporation of plate-type electric heating elements into the body of an electrically heated vessel, particularly a plastic vessel body which exhibits a large dimensional change as the temperature of the water in the vessel is heated from cold to boiling. Plate heating elements are generally of two different types, under-base heating elements, which consist of a metal plate with a shelled heating element clamped on the underside of the metal plate, and slab heating elements, which consist of a Resistive heating tracks or layers on the underside of the electrically insulating base plate. Encased heating elements consist of mineral insulated mounted resistan...
