Description
BACKGROUND OF THE INVENTION
[0001] (1) Field of the Invention
[0002] 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.
[0003] (2) Description of the Prior Art
[0004] 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 FIG. 1 and generally includes a paper-made cup
and a bottom seals the underside of the cup, and at least one heat
isolation part mounted to outside of the cup. The isolation part
includes a connection portion and a downward body portion which is
connected to the connection portion such that a gap is defined
between the cup and the isolation part so as to keep the
temperature of the beverage in the cup. Also, the isolation part
reinforces the structural strength of the cup.
[0005] 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.
[0006] 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 INVENTION
[0007] The 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.
[0008] 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.
[0009] 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] Referring to FIGS. 2 to 7, the heat isolation cup of the
present invention comprises a paper-made cup 10, a lip 20 and a
heat isolation part 30, wherein the cup 10 is includes a bottom 11
sealing the underside of the cup 10 and an open top 12. The lip 20
made of plastic material is connected to the outer periphery of the
open top 12 of the cup 10.
[0018] 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.
[0019] 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 FIGS. 4 and 5, when
the top end of the heat isolation part 30 is engaged with the
positioning portion 21, the bottom end of the heat isolation part
30 can be easily controlled to be connected to desired position of
the cup 10. As shown in FIG. 6, the bottom end of the heat
isolation part 30 can also be without the protrusion and is
directly connected to the outside of the cup 10. This is because
the users hold the cup 10 at the top portion of the cup 10 so that
the gap is defined between the top portion of the cup 10 and the
heat isolation part 30.
[0020] As shown in FIG. 7, the bottom 11 of the cup 10 is made of
plastic material which is integrally formed to the cup 10 by way of
injection molding, heat pressing, high frequency welding or ultra
sonic welding. The bottom 11 includes a positioning groove 111
which is located corresponding to the positioning part 21, and the
bottom end of the isolation part 30 is engaged with the positioning
groove 111.
[0021] 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.
[0022] 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.
