Heat isolation device for cup
A heat isolation cup includes a paper-made cup which has a lip made of plastic material connected to the outer periphery of the open top of the cup. The lip includes a positioning portion. A bottom seals the underside of the cup and includes a positioning groove. A heat isolation part is mounted to outside of the cup and has a top end engaged with the positioning portion, and a bottom end engaged with the positioning groove so as to define a gap defined between the cup and the whole inside of the heat isolation part.

(1) Field of the Invention
The present invention relates to a paper-made cup, and more particularly, to a paper-made cup with a heat isolation part mounted outside of the cup.
(2) Description of the Prior Art
Most of the take-out beverages such as coffee, tea or even juice, are received in a take-out cup which is made by paper material for the economic consideration. However, the paper-made cups do not have satisfied heat isolation feature so that the temperature of the hot beverage cools down quickly and this affects the taste of the hot beverage. There is a improved cup developed which is shown in
Nevertheless, the top section of the isolation part is connected to the connection portion and almost completely attached the outside of the cup, so that when the user holds the cup, most of the users hold the top section of the cup and where there is no gap defined between the cup and the isolation part, the user can feel the high temperature and cannot hold for a long time.
The present invention intends to provide a heat isolation cup wherein the gap is defined between the cup and the isolation part all the way from the top to the bottom so improve the conventional isolation cups.
SUMMARY OF THE INVENTIONThe present invention relates to a heat isolation cup and comprises a paper-made cup having a bottom sealing the underside of the cup and an open top. A lip made of plastic material is connected to an outer periphery of the open top of the cup and has a positioning portion. A heat isolation part is mounted to outside of the cup and has a top end thereof engaged with the positioning portion, and a bottom end of the heat isolation part is fixed to the outside of the cup. A gap is defined between the cup and the heat isolation part.
The primary object of the present invention is to provide a heat isolation cup which includes a paper-made cup and a heat isolation part which is mounted to outside of the cup. A gap is defined between the cup and the whole inside of the heat isolation part so as to have better heat isolation feature.
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 lip 20 is an annular part which is made by plastic material, biobase plastic material or bio-degradable plastic material. The lip 20 is integrally formed to the outer periphery of the open top 12 of the cup 10 by way of injection molding, heat pressing, ultra sonic welding or high frequency welding. The lip 20 has a positioning portion 21 which is a groove.
The heat isolation part 30 is mounted to outside of the cup 10 and has a top end thereof which is engaged with the positioning portion 21, or is connected to the positioning portion 21 by way of gluing or heat fusion. The bottom end of the heat isolation part 30 includes a protrusion which is folded inward toward the cup 10 and is fixed to the cup 10. A gap is defined between the outside of the cup 10 and the whole inside of the heat isolation part 30. The gap has better heat isolation feature. As shown in
As shown in
By the engagement of the top end of the isolation part 30 and the positioning portion 21, the inside of the isolation part 30 is not directly attached to the outside of the cup 10 so as to keep the temperature of the beverage in the cup 10 and the user can hold the cup 10 comfortably.
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.
