DETAILED DESCRIPTION OF THE INVENTION

(9) Referring to FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, and FIG. 6, there are shown a top view, front view, and rear view of a cup sleeve according to an embodiment of the present disclosure, a schematic view of how the cup sleeve looks like after its first strap has been torn off along a cutting line, a schematic view of how the cup sleeve looks like after its first strap and second strap have been torn off along cutting lines, and a perspective view of how the cup sleeve with a handle according to the present disclosure is applied to carrying a cup-shaped container. As shown in FIG. 1 through FIG. 6, the cup sleeve with a handle according to an embodiment of the present disclosure comprises a body 10, a first strap 11 and a second strap 13. The body 10, which is conical and hollow-core, comprises an upper opening 101 and a lower opening 103. The upper opening 101 has a greater diameter than the lower opening 103. A cup-shaped container 20 can pass through the upper opening 101 to enter the body 10 such that the body 10 fits around the cup-shaped container 20.

(10) The body 10 has a first lateral face 102 and a second lateral face 104. The first strap 11 is disposed on the first lateral face 102. The first strap 11 has an inner edge which comes with a first inner cutting line 121 and an outer edge which comes with a first outer cutting line 123. A first folding line 122 is connected between one end of the first inner cutting line 121 and one end of the first outer cutting line 123. A first top end cutting line 124 is connected between the other end of the first inner cutting line 121 and the other end of the first outer cutting line 123. The second strap 13 is disposed on the second lateral face 104. The second strap 13 has an inner edge which comes with a second inner cutting line 141 and an outer edge which comes with a second outer cutting line 143. A second folding line 142 is connected between one end of the second inner cutting line 141 and one end of the second outer cutting line 143. A second top end cutting line 144 is connected between the other end of the second inner cutting line 141 and the other end of the second outer cutting line 143.

(11) To use the cup sleeve to carry the cup-shaped container 20, the user tears off the first strap 11 along the first top end cutting line 124, first inner cutting line 121 and first outer cutting line 123 on the first lateral face 103 and then folds the first strap 11 along the first folding line 122 until the first strap 11 is above the body 10. Afterward, the user tears off the second strap 13 along the second top end cutting line 144, second inner cutting line 141 and second outer cutting line 143 on the second lateral face 104 and then folds the second strap 13 along the second folding line 142 until the second strap 13 is above the body 10. After both the first strap 11 and second strap 13 have been folded to be above the body 10 (for example, above the upper opening 101), the first strap 11 and second strap 13 are connected by engagement to therefore form a handle 15. Therefore, the user uses the handle 15 of the cup sleeve to carry the cup-shaped container 20. After the first strap 11 and second strap 13 have been torn off the first lateral face 102 and second lateral face 104 of the body 10, the first lateral face 102 and second lateral face 104 each form thereon a hollowed-out portion 105.

(12) The first strap 11 is substantially W-shaped and comprises a first top portion 111, a first middle portion 113 and a first tail portion 115. The first top portion 111 and the first tail portion 115 flank the first middle portion 113 symmetrically or asymmetrically. The middle of the first middle portion 113 elevates slightly. One end of the first top portion 111 is defined as the top end of the first strap 11. The other end of the first top portion 111 is connected to one end of the first middle portion 113. One end of the first tail portion 115 is defined as the tail end of the first strap 11 and connected to the first folding line 122. The other end of the first tail portion 115 is connected to the other end of the first middle portion 113. Similarly, the second strap 13 is substantially W-shaped and comprises a second top portion 131, a second middle portion 133 and a second tail portion 135. The second top portion 131 and second tail portion 135 flank the second middle portion 133 symmetrically or asymmetrically. The middle of the second middle portion 133 elevates slightly. One end of the second top portion 131 is defined as the top end of the second strap 13. The other end of the second top portion 131 is connected to one end of the second middle portion 133. One end of the second tail portion 135 is defined as the tail end of the second strap 13 and connected to the second folding line 142. The other end of the second tail portion 135 is connected to the other end of the second middle portion 133. A first included angle (01) is formed between the first middle portion 113 and first top portion 111. A second included angle (02) is formed between the first middle portion 113 and first tail portion 115. A third included angle (03) is formed between the second middle portion 133 and second top portion 131. A fourth included angle (04) is formed between the second middle portion 133 and second tail portion 135. In an embodiment of the present disclosure, the first included angle (01), second included angle (02), third included angle (03) and fourth included angle (04) each range from 90 to 135.

(13) In an embodiment of the present disclosure, the width (W) of the first strap 11 and second strap 13 ranges from 0.8 cm to 3 cm. Using a horizontal line (for example, X-axis) or the bottom (for example, the lower opening 103) of the body 10 as a standard, there is a height difference (H) between the inner cutting line 121/141 and outer cutting line 123/143. The height difference (H) between the inner cutting line 121/141 and outer cutting line 123/143 is adjusted such that the gradient () of the folding line 122/142 ranges from 20 to 40. As experiments affirm, according to the present disclosure, the first strap 11 and second strap 13 are selectively folded upward at the gradient (=2040) to be above the body 10 such that not only do the first strap 11 and second strap 13 engage with each other smoothly, but the first strap 11 and second strap 13 also appropriately extend outward to allow the handle 15 (formed from the first strap 11 and second strap 13) to have broad room for a grip, allowing the user to bring the cup-shaped container 20 conveniently.

(14) In an embodiment of the present disclosure, the inner edge of the first top portion 111 of the first strap 11 has a first inner notch 1111. When the first strap 11 and second strap 13 are folded to be above the body 10, the first inner notch 1111 of the first strap 11 engages with the outer edge of the second strap 13 such that the first strap 11 and second strap 13 together form the handle 15, as shown in FIG. 6. Alternatively, in another embodiment of the present disclosure, the outer edge of the second top portion 131 of the second strap 13 has a second outer notch 1313 such that the engagement of the first inner notch 1111 of the first strap 11 and the second outer notch 1313 of the second strap 13 augments the engagement of the first strap 11 and second strap 13 to thereby enhance the stability of the handle 15. The outer edge of the first top portion 111 of the first strap 11 has a first outer notch 1113. The inner edge of the second top portion 131 of the second strap 13 has a second inner notch 1311. The user either chooses the engagement of the first inner notch 1111 and second outer notch 1313 or chooses the engagement of the second inner notch 1311 and first outer notch 1113.

(15) In the above embodiment, the first strap 11 and second strap 13 engage with each other by notches. Alternatively, in another embodiment of the present disclosure, the top end of the first top portion 111 of the first strap 11 is in the form of an arcuate protruding element, whereas an arcuate opening element is disposed at the second top portion 131 of the second strap 13. When the first strap 11 and second strap 13 are folded to be above the body 10, the first strap 11 and second strap 13 engage with the arcuate opening element through the arcuate protruding element such that the first strap 11 and second strap 13 engage with each other to form the handle 15. In addition to the aforesaid two ways of engagement, it is also feasible for the first strap 11 and second strap 13 to engage with each other and thus be fixed together.

(16) According to the present disclosure, the body 10 is made of a bilayered paperboard. Preferably, the body 10 is made of a corrugated paperboard. In this embodiment, the cup sleeve is made of a corrugated paperboard to not only achieve satisfactory thermal insulation but also function as the strap 11/13 of the handle 15 to thereby attain satisfactory strength, thereby reducing the chance of severance of the strap 11/13 while the user is using the handle 15 of the cup sleeve to carry the cup-shaped container 20.

(17) Referring to FIG. 7 and FIG. 8, there are shown a perspective view of how the cup sleeve with a handle is applied to carrying out cup-shaped containers and an enlarged view of part A in FIG. 7. Referring to FIG. 6 too, according to the present disclosure, the user uses cup sleeves to carry cup-shaped containers 20. As shown in FIG. 6, FIG. 7 and FIG. 8, the first cup-shaped container 20 fits into the body 10 of the first cup sleeve (for example, the upper cup sleeve) such that the first strap 11 and second strap 13 of the first body 10 engage with each other to form a handle 15. Next, the second cup-shaped container 20 fits into the body 10 of the second cup sleeve (for example, the lower cup sleeve) such that the first top portion 111 of the first strap 11 of the second body 10 inserts into the gap between the first body 10 and the first cup-shaped container 20 from the hollowed-out portion 105 of a lateral face (for example, the second lateral face 104) of the first body 10 and exits another lateral face (for example, the first lateral face 102). Hence, the first inner notch 1111 of the first top portion 111 of the first strap 11 of the second body 10 is engageably fixed to a connection structure between the second lateral face 104 and the first lateral face 102 of the first body 10. Likewise, the second top portion 131 of second strap 13 of the second body 10 inserts into the gap between the first body 10 and the first cup-shaped container 20 from the hollowed-out portion 105 of a lateral face (for example, the first lateral face 102) of the first body 10 and exits another lateral face (for example, the second lateral face 104), such that the second inner notch 1311 of the second top portion 131 of the second strap 13 of the second body 10 is engageably fixed to a connection structure between the second lateral face 104 and the first lateral face 102 of the first body 10 to allow the first strap 11 and second strap 13 of the second body 10 to hang on a connection structure between the lateral faces 102, 104 of the first body 10. Afterward, the user grips the handle 15 of the first body 10 to carry the first cup-shaped container 20 in the first body 10 and the second cup-shaped container 20 in the second body 10 hanging below the first body 10. Alternatively, according to another embodiment of the present disclosure, regarding the second body 10, the first top portion 111 of the first strap 11 and the second top portion 131 of the second strap 13 are selectively stapled and thus fixed to the first lateral face 102 and second lateral face 104 of the first body 10. In addition to the aforesaid two ways of fixing the straps in place, the first top portion 111 of the first strap 11 and the second top portion 131 of the second strap 13, which are positioned below the body 10, can be fixed to the body 10 from above.

(18) While the present disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the present disclosure set forth in the claims.
