Abstract
Abstract Dispensers for granular materials such as salt, pepper and other spices and including a container capable of enclosing the said materials therein and at least one dispensing orifice situated in the container and providing for restrained egress of said materials from the interior of the container to the exterior thereof. There is also included an electric heating means which may be wholly or partially embedded in part of the container and positioned in relation to the interior of the container such that heat when generated by said means can pass to said interior and heat granular materials when contained in the container to evaporate any moisture contained therein such that the evaporated moisture leaves the interior of the container by of the orifice. Electrical contact pins are connected to and lead from the heating means and these pins protrude generally perpendicular to a downwardly and inwardly inclined exterior surface of the container and are adapted to be engageable with an electric socket whereby said electric heating means can be electrically connected to a source of electric supply.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
A dispenser for granular materials, comprising a container for enclosing the said materials therein, a dispensing orifice situated in the container and providing for restrained egress of said materials from the interior of the container to the exterior thereof, said container having an exterior surface which is inclined downwardly and inwardly with respect to the vertical axis of the container, an electric heating means at least partially embedded in part of the container and positioned in relation to the interior of the container such that heat when generated by said means can pass to said interior, and electrical contact pins connected to and leading from the heating means and protruding from said inclined surface of the container generally perpendicular to said surface and adapted to be engageaBle with an electric socket, whereby said electric heating means can be electrically connected to a source of electric supply and thereby heated to cause moisture present in said granular materials to evaporate and leave the interior of the container by way of the orifice.
Claim 2
Dependent Claim
171 words
A dispenser for granular materials, comprising a container for enclosing the said materials therein, a dispensing orifice situated in the container and providing for restrained egress of said materials from the interior of the container to the exterior thereof, said container having an exterior surface which is inclined downwardly and inwardly with respect to the vertical axis of the container, an electric heating means at least partially embedded in part of the container and positioned in relation to the interior of the container such that heat when generated by said means can pass to said interior, and electrical contact pins connected to and leading from the heating means and protruding from said inclined surface of the container generally perpendicular to said surface and adapted to be engageaBle with an electric socket, whereby said electric heating means can be electrically connected to a source of electric supply and thereby heated to cause moisture present in said granular materials to evaporate and leave the interior of the container by way of the orifice.
Claim 3
Dependent Claim
39 words
A dispenser as claimed in claim 1 wherein at least a base portion of the container is composed of a mouldable material and the electric heating means and the electric contact pins connected thereto are embedded in said material.
Claim 4
Dependent Claim
46 words
A dispenser for granular materials as claimed in claim 1 wherein the container includes a hollow body part and a base part and the base is composed of a mouldable plastics material in which is embedded the heating means and the electric contact pins connected thereto.
Claim 5
Dependent Claim
20 words
A dispenser for granular materials as claimed in claim 3 wherein the base part is bonded to the body part.
Claim 6
Dependent Claim
35 words
A dispenser for granular materials as claimed in claim 4 wherein access to the interior of the hollow body is gained through an aperture in the base which aperture is closable by a plug member.
Claim 7
Dependent Claim
41 words
A dispenser for granular materials as claimed in claim 3 wherein the connection between the base and the body part is a screw-threaded one and access to the interior of the container is gained by separating the base and body parts.
Claim 8
Dependent Claim
83 words
A dispenser as claimed in claim 1 wherein the container includes a hollow body part and a base part, both composed at least partially of a plastics material, and complementary slots are formed in both the upper surface of the base and the lower surface of the body; and a recess formed in the under surface of the body conjoins with the said slots, the slots being arranged to receive the contact pins and the recess being arranged to receive the heating means.
