Heat flap cup sleeve
Abstract
A cup holder sleeve is formed in pre-assembled, flat-folded form
by die cutting a long, flat band from paperboard material. The flat
sleeve has fold lines scored into the band at spaced apart
positions tapering toward each other, and side edges at opposite
ends of the band. The opposite ends are folded flat at the fold
lines so that the side edges overlap each other and are glued
together at their overlapping surfaces. Within the flat sleeve are
two "D" shaped flaps that when folded back 180 degrees upon the
sleeve itself produce a double paperboard layer of heat protection
for the fingers when placed on the cup.

Claims
1. A cup holder sleeve is formed in pre-assembled, flat-folded form
by die cutting a long, flat band a.) from paperboard material so as
to have a parallel top and bottom curved or wavy edge. b. The top
and bottom edges are parallel to each other so that a common die
cutting knife may be used. This procedure eliminates the need for
the use of two cutting knives with space between the sleeves and
thus uses a minimum of paperboard material. c. The flat sleeve has
fold lines scored into the band at spaced apart positions tapering
toward each other, and side edges at opposite ends of the band. d.
The opposite ends are folded flat at the fold lines so that the
side edges overlap each other and are glued together at their
overlapping surfaces.
2. A cup holder sleeve according to claim 1, a. The flat sleeve has
two "D" shaped die cuts at spaced apart positions. b. The spine of
the "D" is scored while the rounded part of the "D" is die cut
through so that it can be folded back 180 degrees along the spine
of the "D" and form a heat protective barrier for the fingers. c.
The "D" Shaped die cut areas face one another with the rounded
edges of the "D". d. Wherein within the flat sleeve are two "D"
shaped flaps that when folded back 180 degrees upon the sleeve
itself produce a double paperboard layer of heat protection for the
fingers.
3. A cup holder sleeve according to claim 1, a. wherein the
pre-assembled sleeve can be readied for use simply by squeezing on
the outside surfaces so as to bow out the flat-folded glued sleeve
into an annular tapered sleeve with opened top and bottom ends for
inserting a cup therein. b. The two opposing die cut flaps are
folded back 180 degrees onto the sleeve after it is placed on a
cup. This doubles the thickness of the sleeve which doubles the
resistance to the heat of the liquid in the cup. c. When the "D"
flaps are folded back 180 degrees, slight air gaps are formed due
to the thickness of the paperboard. These air gaps further enhance
the heat protective barrier formed by the "D" flaps.
4. A cup holder sleeve according to claim 1, wherein said
flat-folded form allows for compact storage.
5. A cup holder sleeve according to claim 1, wherein one or more
spots of heat activated glue can be applied on the inside of the
sleeve if extra adhesion to the cup is desired.
Description
FIELD OF THE INVENTION
[0001] The present invention relates to a cup holder sleeve for use
as an insulator on a container of a hot beverage such as coffee,
tea, hot cocoa, etc. It is inexpensive to produce and can be
produced with 100% recycled fiber.
BACKGROUND OF THE INVENTION
[0002] This invention relates to a means for protecting the user of
a paper cup from the heat of a hot beverage. Although there are
many types of insulating sleeves in use today, there is still a
need for a sleeve that is inexpensive to produce, stores easily, is
environmentally friendly, and most importantly protects the user's
hand from the hot beverage in the container. Other sleeves do not
address all four of these needs.
BRIEF SUMMARY OF THE INVENTION
[0003] This invention provides beverage container holders (sleeves)
which are environmentally friendly and which provide adequate
insulation for protection from hot beverages.
[0004] A cup holder sleeve is formed in pre-assembled, flat-folded
form by die cutting a long, flat band from paperboard material so
as to have a parallel top and bottom curved or wavy edge. The top
and bottom edges are parallel to each other so that a common die
cutting knife may be used. This procedure eliminates the need for
the use of two cutting knives with space between the sleeves and
thus uses a minimum of paperboard material.
[0005] The flat sleeve has fold lines scored into the band at
spaced apart positions tapering toward each other, and side edges
at opposite ends of the band. The opposite ends are folded flat at
the fold lines so that the side edges overlap each other and are
glued together at their overlapping surfaces. The flat-folded form
allows for compact storage.
[0006] Within the flat sleeve are two "D" shaped flaps that when
folded back 180 degrees upon the sleeve itself produce a double
paperboard layer of protection for the fingers. The flat sleeve has
two "D" shaped die cuts at spaced apart positions. The "D" shaped
die cut areas face one another with the rounded edges of the "D".
The spine of the "D" is scored while the rounded part of the "D" is
die cut through so that it can be folded back along the spine of
the "D" and form a protective barrier for the fingers. When the "D"
flaps are folded back 180 degrees, slight air gaps are formed due
to the thickness of the paperboard. These air gaps further enhance
the protective barrier formed by the "D" flaps.
[0007] The pre-assembled sleeve can be readied for use simply by
squeezing on the outside surfaces so as to bow out the flat-folded
band into an annular tapered sleeve with opened top and bottom ends
for inserting a cup therein. The two opposing die cut flaps are
folded back 180 degrees onto the sleeve after it is placed on a
cup. The cup is grasped by the fingers and thumb at the folded back
flaps. Folding back the flaps doubles the thickness of the sleeve
which doubles the resistance to the heat of the liquid in the cup.
In a preferred embodiment, the sleeve is made of 100% recycled
paperboard material and is printed with graphics. Also, one or more
spots of heat activated glue can be applied on the inside of the
sleeve if extra adhesion of the sleeve to the cup is desired. The
performance of the above blank handling steps is well known in the
paper products industry and is not described further within.
DETAILED DESCRIPTION OF THE INVENTION
[0008] As shown in FIG. 1, a cup holder sleeve 20 is formed from a
long, flat band made from paperboard material so as to have a
parallel top 5 and bottom 6 curved or wavy edges. The top 5 and
bottom 6 edges are parallel to each other so that a common die
cutting knife may be used. This procedure eliminates the need for
the use of two cutting knives with space between the sleeves and
thus uses a minimum of paperboard material, eliminating waste (good
for the environment) and saving material (improving the cost).
[0009] The flat sleeve has fold lines, (FIG. 1) 1 and 2 scored into
the band at spaced apart positions tapering toward each other, and
side edges, (FIG. 1), 3 and 4 at opposite ends of the band. The
opposite ends are folded flat at the fold lines, (FIG. 1) 1 and 2,
so that the side edges, (FIG. 1) 3 and 4 overlap each other, (FIG.
2) 13 and are glued together at their overlapping surfaces, (FIG.
2) 13. The resulting flat-folded sleeve is thus pre-assembled and
allows for compact storage.
[0010] Within the flat sleeve are two "D" shaped flaps, (FIG. 1) 7
and 8, at spaced apart positions, that when folded back 180 degrees
upon the sleeve itself, (FIG. 5) 7 and 8, produce a double
paperboard layer of protection for the fingers, (FIG. 5) 16, and
thumb, (FIG. 5) 17. The "D" shaped die cut areas, (FIG. 1) 7 and 8,
face one another with the rounded edges of the "D", (FIG. 1) 14 and
15. The spines of both of the "D's", (FIG. 1) 9 and 10, are scored
while the rounded part of the "D's", (FIG. 4) 14 and 15, are die
cut through so that they can be folded back along the spines of the
"D's", (FIG. 5) 9 and 10, and form a double-layer protective
barrier for the fingers, (FIG. 5) 16, and thumb, (FIG. 5) 17. When
the "D" flaps are folded back 180 degrees, slight air gaps, (FIG.
5) 11 and 12, are formed due to the thickness of the paperboard.
These air gaps further enhance the protective barrier formed by the
"D" flaps.
[0011] As shown in FIG. 3 the pre-assembled sleeve can be readied
for use simply by squeezing on the outside surfaces with fingers
(FIG. 3) 16 and thumb 17 so as to bow out the flat-folded band into
an annular tapered sleeve with opened top (FIG. 3) 18 and bottom
(FIG. 3) 19 for inserting a cup (FIG. 4) 21 therein. The two
opposing die cut flaps (FIG. 4) 7 and 8 are then folded back 180
degrees onto the sleeve after it is placed on a cup (FIG. 4) 21.
The cup (FIG. 5) 21 is grasped by the fingers (FIG. 5) 16 and thumb
(FIG. 5) 17 at the folded back flaps (FIG. 5) 7 and 8.
[0012] In a preferred embodiment, the sleeve is made of 100%
recycled paperboard material and is printed with graphics. Also,
one or more spots of heat activated glue can be applied on the
inside of the sleeve if extra adhesion of the sleeve to the cup is
desired.
