Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority of Taiwanese application
no. 100129578 filed on Aug. 18, 2011.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] This invention relates to a sleeve, more particularly to a
cup sleeve for providing thermal insulation between a cup and a
user's hand.
[0004] 2. Description of the Related Art
[0005] Referring FIG. 1, a conventional cup sleeve 11 is formed by
bending corrugated paper, and adhering two opposite ends of the
corrugated paper using an adhesive. The cup sleeve 11 serves as a
heat insulator disposed around the circumference of a cup 100, and
facilitates holding of the cup 100.
[0006] However, the corrugated paper has a relatively large
thickness and high cost. Recycling of the cup sleeve 11 is
inconvenient since it is necessary to remove the adhesive from the
cup sleeve 11. Moreover, the cup sleeve 11 is unable to perfectly
fit the circumference of the cup 100 because the cup sleeve 11 has
double thickness at the position where the two opposite ends of the
corrugated paper overlap and are attached to each other. Thus, such
cup sleeve 11 is less likely to be used with a cup having a
constant diameter.
[0007] In Taiwanese Utility Model No. M320352, a cup sleeve 13 has
been proposed (see FIG. 2). The cup sleeve 13 is made of an elastic
material, and formed with a wavy surrounding surface to provide
thermal insulation of the cup 100. Although an advertisement may be
printed on the cup sleeve 13 to attract the user's attention, the
advertisement printed on the wavy surrounding surface is not
appealing.
SUMMARY OF THE INVENTION
[0008] Therefore, an object of the present invention is to provide
a cup sleeve that can overcome the aforesaid drawbacks of the prior
art.
[0009] Accordingly, a cup sleeve of this invention is adapted to be
sleeved around a cup and comprises a sleeve body that is a
multilayered tissue paper. The sleeve body is formed with upper and
lower open ends opposite to each other, and has an outer surface
that includes at least one non-rough region and at least one rough
region.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] Before the present invention is described in greater detail,
it should be noted herein that like elements are denoted by the
same reference numerals throughout the disclosure.
[0026] Referring to FIG. 3, the first preferred embodiment of a cup
sleeve according to this invention is shown, and the cup sleeve is
adapted to be sleeved around a cup 100, which has a lower closed
end 101 and an upper open end 102, and which tapers from the upper
open end 102 to the lower closed end 101. In this embodiment, the
cup sleeve comprises a sleeve body 2 formed with lower and upper
open ends 21 and 22 that are opposite to each other.
[0027] In the sleeve body 2, the lower open end 21 has a perimeter
smaller than that of the upper open end 22. The perimeter of the
lower open end 21 is close to that of the lower closed end 101 of
the cup 100. Similarly, the perimeter of the upper open end 22 is
close to that of the upper open end 102 of the cup 100.
[0028] As shown in FIG. 4, the cup sleeve is formed by folding a
tissue paper to obtain a multilayered tissue paper, overlapping two
opposite ends of the multilayered tissue paper, and embossing the
overlap portion using an embossing device 200 (such as a steel seal
device) formed with a predetermined pattern. After the embossing
process, the cup sleeve is formed with an embossed pattern at the
overlap portion, thereby forming a rough region 24 (see also FIG.
3). The overlap portion, which has been subjected to the embossing
process, has a thickness substantially the same as that of the
non-overlap portion of the cup sleeve. The cup sleeve may be formed
with a plurality of rough regions 24 by virtue of the embossing
process. Preferably, the sleeve body 2 has a plurality of non-rough
regions 23, and a plurality of rough regions 24 that have a number
identical to a number of the non-rough regions 23, and that are
disposed alternately with the non-rough regions 24.
[0029] In this embodiment, the multilayered tissue paper is
obtained by folding the tissue paper twice, such that the cup
sleeve is a four-layer tissue paper to provide thermal insulation.
The cup sleeve has two non-rough regions 23 and two rough regions
24 on an outer surface thereof, and the non-rough regions 23 and
the rough regions 24 are disposed alternately with each other.
[0030] The embossed pattern may be a trademark or other patterns
for attracting the user's attention. Because the cup sleeve of this
invention is made without using an adhesive, it is environmental
friendly and can be produced at a relatively low cost. The rough
regions 24 also facilitate holding of the cup 100. Besides, since
the cup sleeve is a multilayered tissue paper, the cup sleeve can
be removed from the cup 100 to serve as a tissue napkin.
[0031] FIGS. 5 and 6 illustrate the second preferred embodiment of
a cup sleeve according to this invention. The second preferred
embodiment differs from the first preferred embodiment in that, in
the second preferred embodiment, each of the non-rough regions 23
has a pattern part 300 formed with a plurality of through holes
231. Each of the through holes 231 extends through the sleeve body
2. In detail, the pattern part 300 has a plurality of intersecting
strip portions 232 to define the through holes 231, and the through
holes 231 are arranged to form a generally rhombus shape. With the
through holes 231 formed in the generally rhombus shape, the
intersecting strip portions 232 can be stretched circumferentially
such that the cup sleeve of this invention can be expanded to fit
around a cup with a slightly larger size (see FIG. 7).
[0032] FIG. 8 illustrates the third preferred embodiment of a cup
sleeve according to this invention. The third preferred embodiment
differs from the second preferred embodiment in that, in the third
preferred embodiment, the through holes 231 formed in the pattern
part 300 of each of the non-rough regions 23 are formed into a
pattern of a coffee cup. Based on an advertising requirement, the
through holes 231 may be formed into other patterns, such as a
trademark or an advertisement.
[0033] FIG. 9 illustrates the fourth preferred embodiment of a cup
sleeve according to this invention. The fourth preferred embodiment
differs from the third preferred embodiment in that, in the fourth
preferred embodiment, the lower open end 21 has a perimeter equal
to that of the upper open end 22, and the sleeve body 2 is formed
with a plurality of spaced apart slits 221. Each of the slits 221
extends downwardly from the upper open end 22 such that the upper
open end 22 is expandable.
[0034] Referring to FIGS. 10 and 11, when using the cup sleeve
shown in FIG. 9, the lower closed end 101 of the cup 100 is
inserted into the sleeve body 2 from the upper open end 22. With
the progress of the insertion, although the perimeter of the upper
open end 22 is smaller than that of the upper open end 102 of the
cup 100, the cup sleeve of this invention can be sleeved around the
cup 100. This is because the upper open end 22 of the sleeve body 2
can be circumferentially stretched to expand due to the provision
of the slits 221, and because the sleeve body 2 has a thickness
much smaller than that of the corrugated paper used in a
conventional cup sleeve and can be easily shaped by the user's
hands. Accordingly, the upper open end 22 of the sleeve body 2 can
be tightly fitted with the perimeter of the upper open end 102.
[0035] FIG. 12 illustrates the fifth preferred embodiment of a cup
sleeve according to this invention. The fifth preferred embodiment
differs from the third preferred embodiment in that, in the fifth
preferred embodiment, the cup sleeve further comprises a cover body
3, and the lower open end 21 has a perimeter greater than that of
the upper open end 22. The cover body 3 is adapted to cover the
upper open end 102 of the cup 100, and has a top wall portion 31
and a surrounding wall portion 32 extending downwardly from a
periphery of the top wall portion 31. The surrounding wall portion
32 has a bottom end connected to the upper open end 22 of the
sleeve body 2.
[0036] In this preferred embodiment, the bottom end of the
surrounding wall portion 32 surrounds and engages the upper open
end 102 of the cup 100. The sleeve body 2 is formed with a
perforated tearing line 222 extending annularly along the upper
open end 22 of the sleeve body 2 in proximity to the cover body 3
such that the cover body 3 can be removed from the sleeve body 2.
The top wall portion 31 may be formed with a drinking opening (not
shown). Otherwise, if no drinking opening is formed, the user may
remove the cover body 3 to drink the beverage in the cup 100.
[0037] In addition, as shown in FIG. 12, because the perimeter of
the lower open end 21 of the sleeve body 2 is greater than that of
the lower closed end 101 of the cup 100, the sleeve body 2 can be
further shaped or folded to enhance the thermal insulation effect
of the cup sleeve.
[0038] FIGS. 13 and 14 illustrate the sixth preferred embodiment of
a cup sleeve according to this invention. The sixth preferred
embodiment differs from the fifth preferred embodiment in that, in
the sixth preferred embodiment, the sleeve body 2 is in a form of a
circular ring shape.
[0039] To sum up, the cup sleeve according to this invention can
provide thermal insulation between a cup and a user's hand, and the
sleeve body of the cup sleeve can be easily recycled and printed
with an advertisement.
[0040] While the present invention has been described in connection
with what are considered the most practical and preferred
embodiments, it is understood that this invention is not limited to
the disclosed embodiments but is intended to cover various
arrangements included within the spirit and scope of the broadest
interpretations and equivalent arrangements.
