Abstract: An electric coffee percolator having a glass vessel removably mounted on a combination heater and handle base assembly wherein the upper end of the glass vessel has a non-breakable plastic one-piece split collar member sealingly mounted thereon and having a pouring spout formation. A positive twist-lock cover is provided for the collar member. A second embodiment has a secondary latching arrangement operable to latch the vessel to the base assembly should a primary latching arrangement be inoperable due to a partial misalignment of the vessel on the base assembly.

Abstract: An electric coffee percolator having a glass vessel with an opening in the bottom through which a metallic well for a pump assembly extends. Associated with the well are electric heating elements for both operating the percolator pump and keeping the contents of the vessel warm after coffee making has been completed. The seal between the metallic heater and well portion and the glass vessel is accomplished by an annular gasket which is of substantial vertical height and includes an undercut at the lower edge thereof to receive and lock the glass vessel portion in sealed engagement with the metallic well portion. All of the functional parts enclosed in the base of the percolator including the thermostat, the main heating element, and the keep warm heater are supported in a unitary assembly which rests upon a plastic base from which the handle is also supported. The upper portion of the handle includes a simple latch which detachably engages the upper edge of the glass vessel, the latch actuating portion being easily accessible to the hand of the user and in its released position being substantially exposed so as to warn the user that the latch is not engaged with the glass vessel.

Abstract translation: 一种具有在底部开口的玻璃容器的电动咖啡渗滤器，用于泵组件的金属孔通过所述玻璃容器延伸。 与该井相关的是用于操作渗滤泵的电加热元件，并且在咖啡完成之后保持容器的内容物保温。 金属加热器和井口部分与玻璃容器之间的密封是通过一个环形垫片实现的，该环形垫片具有相当大的垂直高度，并且在其下边缘处包括底切以将玻璃容器部分与金属井口密封接合 。 封闭在包括恒温器，主加热元件和保温加热器的渗滤器的底部中的所有功能部件被支撑在整体组件中，该整体组件搁置在也支撑手柄的塑料基座上。 手柄的上部包括可拆卸地接合玻璃容器的上边缘的简单的闩锁，闩锁致动部分可容易地接触到使用者的手，并且在其释放位置基本上暴露以便警告使用者 闩锁不与玻璃容器接合。
