Embodiment 1
(13) FIG. 1 is a sectioned-ring-shaped paper sheet used for making conventional cups. FIG. 2 to FIG. 4 provide a paper cup of embodiment 1. FIG. 2 is a sectioned-ring-shaped paper sheet 1 used for making the paper cup provided in the present embodiment. Referring to FIG. 2, an edge 3 of a top arch of the sectioned-ring-shaped paper sheet 1 is provided with a protruding rectangular paper sheet 11 that is integrally formed with the sectioned-ring-shaped paper sheet 1. The protruding rectangular paper sheet 11 could be of any height within the range of 10 mm-100 mm. An edge 4 of a bottom arch of the sectioned-ring-shaped paper sheet 1 is provided with a notch 12 corresponding to the protruding rectangular paper sheet 11. FIG. 3 provides a schematic top plan view of the paper cup, wherein the sectioned-ring-shaped paper sheet 1 is rolled and affixed. The protruding rectangular paper sheet 11 is rolled via a cylindrical mold to form an upper portion of a straw; an outer surface of the straw and an inner surface of the paper cup are then adhered by glue. Referring to FIG. 4, a lower portion of the straw is connected to a receiving room of the paper cup via the notch 12. The paper cup provided in the embodiment of the present invention is integrally formed by the rolled paper straw and a cup body, which requires no additional straw and solve the problem of environmental pollution caused by the consumption of plastic straws.
Embodiment 2
(14) FIG. 5 and FIG. 6 provide a second embodiment of a paper cup. Referring to FIG. 5, the differences between the sectioned-ring-shaped paper sheet 1 of Embodiment 1 and Embodiment 2 are that: in Embodiment 2, a left-side protruding rectangular paper sheet 11 and a right-side protruding rectangular paper sheet 11 are respectively arranged on two extreme edge portions of the edge 3 of the top arch of the sectioned-ring-shaped paper sheet 1, a left-side notch 12 and a right-side notch 12 are correspondingly arranged on two extreme edge portions of the edge 4 of the bottom arch of the sectioned-ring-shaped paper sheet 1. The two protruding rectangular paper sheets 11 are rolled into via the cylindrical mold to form two upper portions of straws. The outer surfaces of the two straws are adhered by glue. The lower portions of the two straws are connected to the receiving room of the paper cup via the notch 12. The present embodiment achieves the object of large consumption of drinks by way of providing two rolled straws.
Embodiment 3
(15) FIG. 7 and FIG. 8 provide a third embodiment of a paper cup. Referring to FIG. 7, the paper cup comprises a sectioned-ring-shaped paper sheet 1 for making a cup body and a round paper sheet for making a cup bottom, the sectioned-ring-shaped paper sheet 1 and the round paper sheet being affixed to form the paper cup. An edge 3 of a top arch of the sectioned-ring-shaped paper sheet 1 is provided with a left-side protruding rectangular paper sheet 11 and a right-side protruding rectangular paper sheet 11, which both are integrally formed with the sectioned-ring-shaped paper sheet 1. An edge 4 of a bottom arch of the sectioned-ring-shaped paper sheet 1 is provided with a right-side notch 12 corresponding to the right-side protruding rectangular paper sheet 11. Referring to FIG. 8, the left-side protruding rectangular paper sheet 11 and a first strip portion 113 of the sectioned-ring-shaped paper sheet 1 together are pressed by the cylindrical mold to form at least one outwardly-arched curved portion 111 of the straw. The right-side protruding rectangular paper sheet 11 and a second strip portion 114 of the sectioned-ring-shaped paper sheet 1 together are pressed by the cylindrical mold to form at least one inwardly-arched curved portion 112 of the straw, wherein the second strip portion 114 of the sectioned-ring-shaped paper sheet 1 is arranged between the right-side protruding rectangular paper sheet 11 and the right-side notch 12. The outwardly-arched curved portion 111 of the straw and the inwardly-arched curved portion 112 of the straw are affixed to form an inner space of the straw; the inner space of the straw communicates with the receiving room of the paper cup via the right-side notch 12. The paper cup provided in the present embodiment is integrally formed by the rolled paper straw and the cup body. Since paper straws are environmentally-friendly, they will be degraded to disappear into the soil after several months of use and will not pollute the environment.
Embodiment 4
(16) FIG. 9 provides a basically same embodiment as embodiment 1. The only difference is that a top of the protruding rectangular paper sheet 11 is pressed with multiple folds through a mold. When rolling the protruding rectangular paper sheet 11 into a straw, the top of the straw will form as a concertina-type hinge allowing the top of the straw to bend for convenience.
(17) The above-mentioned embodiments are the preferred embodiments of the present invention. Variations and modifications are allowed within the scope of the invention. Those skilled in the art will appreciate that the features described above can be combined in various ways to form multiple variations of the invention. As a result, such variations fall within the scope of the protection to the present invention.
