RECIPIENT A BOISSONS ELECTRIQUE INDIQUANT LA TEMPERATURE

ELECTRIC TEMPERATURE INDICATING DRINKING VESSEL

Abrégé anglais

Disclosed is a drinking vessel, cup or mug enhanced to provide a digital
thermo electronic
display of the temperature of the liquid contents. The display of the
temperature of the liquid
contents is presented in a digital format and serves to inform and/or warn the
user in order for the
user to avoid the drinking of liquids of extreme temperature. A sensor is
affixed to the bottom
interior of the plastic liner. The sensor probe within the plastic liner
provides for the temperature
sampling its contents. The sensor probe is connected to the electronic
integrated circuit board
mounted between the plastic liner and the outer stainless steel or plastic
outer shell. The bottom
of the inner plastic liner houses the switch for changing the display readout
between farenheight
and Celsius and also contains the battery.

Revendications

CLAIMS
The embodiments of the invention in which an exclusive property or privilege
is
claimed are defined as follows:
1. A drinking cup, mug or vessel, which embodies an integrated battery powered
digital thermometer to display the temperature of liquids contained therein.
2. A drinking cup, mug or vessel as claimed in claim 1, which combines an
assembly of a stainless steel or plastic outer shell, a plastic inner liner, a
plastic lid and a
plastic bottom cap with the integration of a sub assembly battery powered
digital
thermometer with the temperature display imbedded on the upper portion of the
outer
shell.
3. A drinking cup, mug or vessel as claimed in claim 1 and claim 2, in which
the
components of the integrated circuit board thermometer is imbedded between the
outer
shell and the inner liner to provides a digital numeric readout capable of
being switched
to read in either Fahrenheit or Celsius being powered by a AAA battery and
having the
switches for on /off and Fahrenheit or Celsius display mounted within a recess
on the
bottom exterior of the inner plastic liner and covered by a plastic cap which
serves as the
base of the entire assembly.

SPECIFICATION
ELECTRIC TEMPERATURE INDICATING DRINKING VESSEL
This invention, "Electric Temperature Indicating Drinking Vessel" enhances the
utility of
the ordinary drinking cup, mug or vessel by providing visual information on
the
temperature of liquids contained therein, thereby allowing the user to take
note of the
temperature of the liquid contained therein before using or consuming the
contents of the
cup mug or vessel.
BACKGROUND OF THE INVENTION
Drinking cups and mugs have long been known since the Bronze Age and widely
used.
Most commonly drinking vessels were crafted from pottery or wood and later
metal and
glass. Much later plastics were introduced into their manufacture. These
drinking vessels
are most commonly cylindrical and may or may not have a handle or stem. They
may be
open at the top or may have a lid or cap of some type, either hinged or held
in place by
friction or fasteners.
Drinking vessels are commonly used to contain beverages of a wide range of
types and
temperatures. Thus far, an indication of temperature of the contents was by
means of the
senses of the hand or mouth, and in one innovation by means of the changing of
color of
the container.
Drinking vessels which bear various innovations are shown, for example, in the
following
United States of America patents and Canadian patents:
324453 Freeman
2134924 Shikami, U.S.A.
2274588 Marshall & Leslie

SUMMARY OF THE INVENTION
It is the object of this invention to enhance the utility and safety to the
user by visually
displaying the temperature of the contents of the "Electric Temperature
Indicating
Drinking Vessel" by means of an integral battery powered digital thermometer.

DETAILED DESCRIPTION OF THE INVENTION
In the particularly enhanced embodiment of the invention illustrated, the
outer shell 10 is
of cylindrical tube having a rectangular opening 18 oriented horizontally on
the upper
portion wherein the digital thermometer assembly 13 is inserted from the
interior side.
The plastic liner 12 is thermoformed so that the upper edge friction fits onto
the top edge
of outer shell 10. The plastic liner 12 has a recessed area 14 that when the
plastic liner is
seated onto the upper edge of outer shell 10 which aligns with. the
rectangular opening 18
thereby creating a space for the embedded digital thermometer assembly 13
between the
plastic liner 12 and outer shell 10.
The inner plastic liner 12 tapers inward as it extends downward from the top
edge of the
outer shell 10. The bottom surface of the liner 12 is recessed upward on the
lower
exterior surface to provide a containment area for a temperature sensor 15, a
battery 16
and a switch 17. The lower edge of the liner aligns parallel with the lower
edge of the
outer shell 10 where the tapered surface becomes cylindrical in order to mate
with the
bottom cover 11. The upper surface of the liner recess is perforated by a
single hole into
which the temperature probe 15 is mounted to extend from the exterior of the
recessed
surface into the base interior of the liner 12 where it can come into contact
with the
contents if any, of the liner 12 and thereby transmit the electrical signal to
the electric
thermometer assembly 13 by means of wiring for translation and display of the
contents
temperature.
The bottom thermoformed plastic cap 11 incorporates two cylindrical extensions
of
which the inner bears integral threads which mate with the liner 12 in order
to lock the
bottom cap 11 in place and close off the bottom of the outer shell 10 and the
plastic inner
liner 12.
