(1) Field of the Invention
The present invention relates to a cup assembly, and more particularly, to a paper cup and its cap which is rotated to be connected to the cup.
(2) Description of the Prior Art
The conventional take-out service for coffee or juice generally uses a cup with a cap mounted on the cup, and the cup and cap are shown in
The present invention intends to provide a cup assembly wherein the cap is rotated an angle to be mounted to the cup and the cap can be easily removed from the cup when needed.
SUMMARY OF THE INVENTIONThe present invention relates to a cup assembly and comprises a cup made of paper material and a lip is formed on a periphery of an open top of the cup. The lip is made of plastic material and has a first spiral portion formed thereon. A cap has a second spiral portion formed on an inside thereof and the second spiral portion is engaged with the first spiral portion.
The primary object of the present invention is to provide a cup assembly wherein the cap is rotated an angle to be mounted on or removed from the cup.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The cap 20 has a hole 21 defined therethrough so that the coffee or juice can be accessed via the hole 21 by a straw. A second spiral portion 22 is formed on an inside thereof and the second spiral portion 22 is engaged with the first spiral portion 121.
The spiral direction of the first spiral portion 121 and the spiral direction of the second spiral portion 22 are in opposite to each other so that when the first and second spiral portions 121, 22 can be easily engaged with each other.
When mounting the cap 20 to the cup 10 or removing the cap 20 from the cup 10, the user simply rotates the cap 20 an angle to easily achieve the purpose without shaking the cup 10 so as to prevent the coffee or juice in the cup 10 from splitting out.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
