CROSS REFERENCE OF RELATED APPLICATION
[0002] This Non-provisional application claims priority under 35
U.S.C. .sctn.119(a) on Patent Application No(s). 101221329 filed in
Taiwan, Republic of China on Nov. 2, 2012, the entire contents of
which are hereby incorporated by reference.
BACKGROUND OF THE PRESENT INVENTION
[0003] 1. Field of Invention
[0004] This invention relates to a heat insulating apparatus for a
cup and, more particularly, to a foldable heat insulating cup
sleeve.
[0005] 2. Description of Related Arts
[0006] In daily life, hot beverages are often served in containers
with poor heat insulation such as disposable paper cups, ceramic
cups, or glass cups and so on. These containers easily result in
discomfort to users when they hold the containers, and even
scalding may occur. Otherwise when the container has smooth outer
surface, the container may easily slip out of the user's hand thus
causing broken and pollution. For a take-out hot beverage, a heat
insulating cup sleeve is usually used to wrap around the cup to
prevent scalding due to the hot beverage when the user's hand holds
the cup. Shops usually using the heat insulating cup sleeves just
taking domestic coffee shops and beverage shops for example are
already tens of thousands. If the statistics scope is expanded to
the global countries or areas, the consumption is hard to
estimate.
[0007] Although the conventional cup sleeves are simple in
structure, most of them are made of paper material and are
cylindrical for wrapping around the outer walls of the cups.
Accordingly, to keep the shape of the cup sleeve, an adhering
process has to be needed or the cup sleeve has to be bayonet-shaped
thus increasing manufacture cost.
[0008] Further, this kind of heat insulating cup sleeve is
basically disposable thus causing material waste and environment
pollution.
SUMMARY OF THE PRESENT INVENTION
[0009] The invention provides a heat insulating cup sleeve to
improve the prior art. The heat insulating cup sleeve has some
advantages such as simple structure, convenient manufacture, and
material saving. Further, when different materials are used, the
heat insulating cup sleeve can be reusable thus being
environmentally friendly.
[0010] A heat insulating cup sleeve according to the invention is
formed by folding a blank and includes a first heat insulating
sheet having a first holding portion, a first extending portion,
and a first fold line and a second heat insulating sheet having a
second holding portion, a second extending portion, and a second
fold line. The second fold line is connected with the first holding
portion, and the first fold line is connected with the second
holding portion. The first holding portion and the second holding
portion are capable of being folded downward along the second fold
line and the first fold line, respectively, to form an opening.
When a cup is inserted into the opening, the first holding portion
and the second holding portion press against an outer surface of
the cup.
[0011] Compared with the prior art, the invention can nearly save
50% materials, and only a cutting process is needed for manufacture
while folding and adhering processes have to be needed in the prior
art. In addition, the volume is reduced due to the material saving,
thus saving transport cost and increasing reserve. Further, the
heat insulating cup sleeve can be grouped into two categories
according to the manufacture materials: disposable one and reusable
one to be environmentally friendly and save resources.
[0012] These and other features, aspects, and advantages of the
present invention will become better understood with regard to the
following description, appended claims, and accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0019] In one embodiment (please refer to FIG. 1), a heat
insulating cup sleeve 1 is made of paper material and mainly
includes a first heat insulating sheet 11 and a second heat
insulating sheet 12. The first heat insulating sheet 11 has a first
holding portion 111, a first extending portion 112, and a first
fold line 113. The second heat insulating sheet 12 has a second
holding portion 121, a second extending portion 122, and a second
fold line 123. The second fold line 123 is connected with the first
holding portion 111, and the first fold line 113 is connected with
the second holding portion 121. The first holding portion 111 and
the second holding portion 121 can be folded downward along the
second fold line 123 and the first fold line 113, respectively, to
form an opening 14 (please refer to FIG. 4). When a cup is inserted
into the opening 14, the first holding portion 111 and the second
holding portion 121 press against an outer surface of the cup. The
heat insulating cup sleeve 1 has a cut line 13 for separating the
heat insulating cup sleeve 1 into the first heat insulating sheet
11 and the second heat insulating sheet 12 (please refer to FIG. 1,
FIG. 2, and FIG. 3). The cut line 13 is S-shaped for maximizing the
areas of the heat insulating sheets and protecting hands better.
However, the invention is not limited thereto.
[0020] In another embodiment in FIG. 5, the first heat insulating
sheet 11 and the second heat insulating sheet 12 have a plurality
of protrusions, respectively, for preventing slippage and providing
adequate heat insulation.
[0021] In a third embodiment in FIG. 6, the heat insulating cup
sleeve 1 is made of silica gel, and the first heat insulating sheet
11 and the second heat insulating sheet 12 have a plurality of
protruding textures, respectively. The textures are strip-shaped or
ring-shaped. The heat insulating cup sleeve 1 made of silica gel
can be used repeatedly, and the protruding textures can help
preventing slippage and providing adequate heat insulation.
[0022] The heat insulating cup sleeve 1 can be used easily (please
refer to FIG. 4). At the S-shaped cut line 13 of the heat
insulating cup sleeve 1, the first heat insulating sheet 11 and the
second heat insulating sheet 12 can be folded downward along the
first fold line 113 and the second fold line 123, respectively, to
allow the heat insulating cup sleeve 1 to form a round opening 14.
When the round opening 14 is kept, the first holding portion 111
and the second holding portion 121 should be opened by one hand,
and the bottom of the cup should be inserted into the opened
opening 14 by the other hand. Then the heat insulating cup sleeve 1
is pushed upward until the opening 14 holds the cup closely. At
this time, the first holding portion 111 and the second holding
portion 121 press against an outer surface of the cup. When using
the heat insulating cup sleeve 1, a user's hand can hold the first
holding portion 111 and the second holding portion 121 pressing
against the outer surface of the cup for heat insulation.
[0023] Although the present invention has been described in
considerable detail with reference to certain preferred embodiments
thereof, the disclosure is not for limiting the scope of the
invention. Persons having ordinary skill in the art may make
various modifications and changes without departing from the scope
and spirit of the invention. Therefore, the scope of the appended
claims should not be limited to the description of the preferred
embodiments described above.
