Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application is a continuation of pending
International patent application PCT/KR2010/000199 filed on Jan.
13, 2010, which designates the United States and claims priority
from Korean Patent Application No. 20-2009-0001022 filed on Jan.
30, 2009. The content of all prior applications is incorporated
herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to a paper cup, and more
particularly, to a paper cup including a heat insulating material
that is not separable from a main body of the paper cup so that a
user may hold the paper cup conveniently even when a hot or cold
beverage is in the paper cup.
BACKGROUND OF THE INVENTION
[0003] For containing beverages such as coffee or juice, paper cups
are mainly used in vending machines or coffee shops. FIG. 1 shows
an example of a conventional paper cup 1. The conventional paper
cup 1 includes a cup main body 2 formed as a cylinder for
containing the beverage, and a curled rim 3 formed on an upper end
portion of the cup main body 2 for protecting lips of a user and
improving configuration maintenance of the cup main body 2.
[0004] However, the conventional paper cup 1 is generally formed of
thin paper, and thus, when hot coffee or cold juice is in the
conventional paper cup 1, the user may experience difficulty in
holding the conventional paper cup 1 due to heat or cold
transferred to the hand of the user.
[0005] Therefore, coffee shops selling hot coffees in the paper
cups 1 mainly use a holder 4 that is formed as a loop band
fabricated using corrugated fiber board, so that the conventional
paper cup 1 containg hot coffee is inserted into the holder 4.
[0006] However, as shown in FIG. 1, the holder 4 is inserted from a
lower portion of the conventional paper cup 1, and thus, when the
user puts the conventional paper cup 1 on a table or in a cup
holder of a vehicle, the holder 4 is likely to separate from the
conventional paper cup 1 and fall down on the table or the cup
holder, for example. Therefore, when the user wants to hold the
paper cup 1 again, the user must inconveniently insert the holder 4
on the table or the cup holder on the paper cup 1 again to hold the
conventional paper cup 1.
SUMMARY OF THE INVENTION
[0007] The present invention provides a paper cup having an
improved structure in which a heat insulating material is not
separated from a cup main body of the paper cup so that a user may
conveniently hold the paper cup in which a hot or cold beverage is
contained.
[0008] According to an aspect of the present invention, there is
provided.
[0009] According to another aspect of the present invention, there
is provided.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The above and other features and advantages of the present
invention will become more apparent by describing in detail
exemplary embodiments thereof with reference to the attached
drawings in which:
[0011] FIG. 1 is a perspective view of a conventional paper
cup;
[0012] FIG. 2 is a perspective view of a paper cup according to an
embodiment of the present invention;
[0013] FIG. 3 is a cross-sectional view of the paper cup
illustrated in FIG. 2 taken along a line III-III;
[0014] FIG. 4 is a perspective view of a paper cup according to
another embodiment of the present invention; and
[0015] FIG. 5 is a cross-sectional view of the paper cup

DETAILED DESCRIPTION OF THE INVENTION
[0016] Hereinafter, embodiments of the present invention will be
described in detail with reference to accompanying drawings.
[0017] FIG. 2 is a perspective view of a paper cup 100 according to
an embodiment of the present invention, and FIG. 3 is a
cross-sectional view of the paper cup 100 taken along line
III-III.
[0018] Referring to FIGS. 2 and 3, the paper cup 100 according to
the present embodiment contains beverages, for example, and is able
to be held by a user, and the paper cup 100 includes a cup main
body 10 and a heat insulating material 20.
[0019] The cup main body 10 is a cylindrical member having an open
upper portion for receiving beverages from the open upper
portion.
[0020] A curled rim 11 is formed at an upper end portion of the cup
main body 10 so as to protect the lips of a user and improve the
configuration maintenance of the cup main body 10. The curled rim
11 is formed by rolling the upper end of the cup main body 10
out.
[0021] The heat insulating material 20 is a member for reducing
thermal conductivity between the beverage contained in the paper
cup 100 and the hand of the user holding the paper cup 100, and may
be, for example, non-woven fabric, corrugated fiber board, or
aerated synthetic resin. In the present embodiment, the heat
insulating material 20 is a transparent aerated synthetic
resin.
[0022] The aerated synthetic resin used as the heat insulating
material 20 is transparent so that characters or figures displayed
on an outer wall of the cup main body 20 beneath the heat
insulating material 20 may be recognized by the user through the
heat insulating material 20.
[0023] The heat insulating material 20 is circumferentially
attached to the outer wall of the cup main body 10 so as not to
separate from the cup main body 10. A well-known adhesive having
certain degrees of cold-tolerance and thermal-resistance is applied
between the heat insulating material 20 and the outer wall of the
cup main body 10 so as to attach the heat insulating material 20 to
the cup main body 10.
[0024] When the paper cup 100 having the above-described structure
is used, heat or cold of the beverage contained in the paper cup
100 is rarely transferred to the hand of the user holding the paper
cup 100, even if the hot or cold beverage is in the paper cup 100.
Thus, the user may hold the paper cup 100 continuously without any
inconvenience from the hot or cold beverage.
[0025] In addition, since the heat insulating material 20 is
attached to the outer wall of the cup main body 10, the heat
insulating material 20 is not separable from the cup main body 10.
Therefore, even when the user holds the paper cup 100 again after
putting the paper cup 100 on a table for a while, the user may
conveniently hold the paper cup 100 since there is no need to
attach the heat insulating material 20 again to the paper cup 100,
unlike the conventional paper cup 1 used with the holder 4.
[0026] On the other hand, the aerated synthetic resin used as the
heat insulating material 20 is transparent enough for the user to
recognize character information or figure information displayed on
the outer wall of the cup main body 10 beneath the heat insulating
material 20. Therefore, trademarks or advertisements of a beverage
merchandiser, which are generally displayed on a paper cup, may not
be covered by the heat insulating material 20 so that the user
recognizes the trademarks or the advertisements.
[0027] FIG. 3 illustrates a paper cup 200 according to another
embodiment of the present invention. The paper cup 200 includes the
cup main body 10 and a heat insulating material 120 disposed on
some parts of an outer wall of the cup main body 10. Since the
paper cup 200 has the nearly same structure as that of the paper
cup 100 according to the previous embodiment, differences
therebetween will be described as follows.
[0028] The heat insulating material 120 of the paper cup 200
includes a first member 121, to which a part of the hand of the
user holding the paper cup 200 contacts, and a second member 122,
to which the other part of the hand of the user holding the paper
cup 200 contacts, that is disposed on an opposite side to the first
member 121.
[0029] According to the paper cup 200 having the above-described
structure, since the heat insulating material 120 is attached to
some parts of the outer wall of the paper cup 200, unlike the paper
cup 100 in which the heat insulating material 20 surrounds the
entire outer wall of the cup main body 10, an area of the aerated
synthetic resin is reduced and manufacturing costs of the paper cup
200 may be reduced.
[0030] According to the present invention, since a heat insulating
material is attached to an outer wall of a cup main body, a heat
insulating material is not separable from the cup main body, and
thus, the user may conveniently hold the paper cup even when a hot
or cold beverage is in the paper cup.
[0031] While the present invention has been particularly shown and
described with reference to exemplary embodiments thereof, it will
be understood by those of ordinary skill in the art that various
changes in form and details may be made therein without departing
from the spirit and scope of the present invention as defined by
the following claims.
