Coffee cup

The present invention relates generally to a coffee cup and in particular to a cup set having three different layers, where the first layer is a cup-like container having a filter formed therein, and the second layer is a coffee cup being used to receive the filtered coffee, the third layer is a base formed beneath the second layer which is supported by the same.

FIELD OF THE INVENTION 
The present invention relates generally to a coffee cup and in particular 
to a cup set having three different layers, where the first layer is a 
cup-like container having a filter formed therein, and the second layer is 
a coffee cup being used to receive the filtered coffee, the third layer is 
a base formed beneath the second layer which is supported by the same. 
BACKGROUND OF THE INVENTION 
In our daily life, influenced by the wonderful smell and by the 
encouragement of environment, the number of coffee drinkers have gradually 
increased. Owing to the increasing coffee drinking population, and also 
because of the their special criticism to the coffee, a variety of coffee 
makers are being produced to meet the different requirements of the coffee 
drinkers. 
Among the most popular coffee makers, two of them are the most common types 
known to the art, one is electric-type coffee maker using electricity as 
the source of boiling the water, the other is using alcohol as the source 
of the heating procedure; the electric-type coffee maker uses electricity 
to heat up the metal pipes formed therein, and the heat from the metal 
pipes will boil the water and then gradually using the boiling water to 
achieve the desired filtering effect; the alcohol type coffee maker uses 
the characteristic feature of alcohol to boil the water inside the coffee 
maker, and then step by step the boiled water inside the coffee maker will 
drip into the coffee powder which will then be dissolved by the boiled 
water and become liquid coffee dripping into a container. These two kinds 
of coffee makers both can achieve the desired purpose of dissolving the 
coffee powder into liquid type coffee, yet, because the facilities of 
achieving the desired purpose require electricity, alcohol, different 
kinds of cups and even tender caring during the filtering procedure, they 
are generally considered to be indoor use. Once we are out of the house, 
and still want to have fresh coffee ready to be served, these two kinds of 
coffee makers are almost impossible to serve this kind of requirement, 
even the alcohol type coffee maker can not meet this purpose, unless a lot 
of precautions are being taken into consideration before making a pot of 
fresh coffee. 
It is therefore desirable to provide a coffee maker for making fresh coffee 
in any difficult situation, which is simple in structure and thus cheap in 
cost to be used for personal requirement. 
SUMMARY OF THE INVENTION 
An object of the present invention is to provide a coffee maker which is 
simple in structure, easy to use and cheap in cost for personal 
requirement of making fresh coffee. 
It is another object of the present invention to provide a filtering device 
for filtering the dissolved coffee powder, which is simple in structure 
and cheap in cost. 
It is a further object of the present invention to provide a thermal 
isolation base having a handle formed on the side of its outer wall, and 
multiple projections in the bottom of the base, which is designed to 
support the coffee cup and to isolate the heat from the liquid coffee. 
To achieve the above objections, there is provided a filtering device for 
filtering the dissolved coffee powder comprising a thermal insolation 
cover and a filtering net. The thermal insolation cover is provided to 
close the top opening for the preservation of thermal energy of the high 
temperature of the water added into the device. A filtering net is 
provided to filter out the dissolved coffee powder and provide fresh 
coffee. A coffee cup having its upper radius slightly bigger than the 
radius of the filtering device is connected directly under the filtering 
device, for receiving the dripping coffee. And a base formed to receive 
the coffee cup and to isolate the heat of the dissolved coffee has 
multiple projections formed inside the base which is connected directly 
under the coffee cup to support and to provide stability to the coffee cup 
.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIG. 1 and FIG. 2, a coffee cup comprises a container 20 
having a thermal insolation cover 10 used to cover the upper opening of 
the container 20, a glass cup 30 and a base 40 where the glass cup 30 is 
housed therein. The cover 10 is used to close the upper opening of the 
container 20, and a circular part or handle 22 is formed at the upper end 
of the container 20, for holding a spoon 25. The radius of the lower part 
23 of container 20 is smaller than the upper part. As seen in FIG. 3, an 
opening 24 formed through the bottom of the container 20 has an outer, 
bigger portion 241 and an inner, smaller portion 242. The diameter of 
portion 241 is just slightly bigger than the diameter of a filter 21 for 
receiving the filter 21. Through the hole formed in the center of portion 
242, the filtered coffee will then flow into the glass cup 30. Cup 30 has 
a diameter which is a little bigger than the bottom of the container 20, 
therefore, the glass cup 30 can be mounted onto container 20 with these 
two surfaces tightly engaged. The lower part of the glass cup 30 also 
comprises a portion having smaller diameter for receiving a base 40 formed 
beneath the glass cup 30. The base 40 acting as a cushion to the glass cup 
30 has a handle 41 formed on the side of the base 40. The upper end of the 
handle 41 is not attached and extends higher than the base 40 so as to be 
in contact with the glass cup 30. 
Referring to FIG. 3, the sectional view of the present invention, on the 
bottom side of the base 40, purity projections 42 are formed to act as 
cushion to the glass cup 30, and to receive the glass cup 30 therein. 
The best embodiment of the present invention is shown in FIG. 4. When using 
the coffee cup, first lift off the cover 10, and put certain amount of 
coffee powder 50 in the container 20. Then assemble and then the rest of 
the parts of the coffee cup as previously described. When all the parts of 
the coffee cup are assembled together, hot water is added to the container 
20, then the coffee powder 50 in the container 20 will gradually dissolve 
and flow into the glass cup 30. After a while, a fresh, strong coffee is 
ready. 
Thus, although the invention has been shown and described with respect to 
exemplary embodiments thereof, it should be understood by those skilled in 
the art that the aformentioned changes and various other changes, thereto, 
can be made without departing from the spirit and scope of the invention.
