STRAW CUP LID

Abstract

A straw cup lid is provided. The straw cup lid includes a lid and a water stopping member. A pivot hole is disposed on a lid upper surface while a pivot pin is protruding from a bottom of the water stopping member and mounted into the pivot hole to pivotally connect the water stopping member with the lid. A convection hole is located at the lid upper surface and adjacent to the pivot hole and penetrating the lid upper surface while a corresponding protruding block on the bottom of the water stopping member is engaged with the convection hole. The lid upper surface is concave to have a lower central area. A straw slot is on the lid for allowing a top of a straw to protrude therefrom. A water stopping plug on the bottom of the water stopping member is inserted into the straw.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0025] In order to learn technical content, purposes and functions of the present invention more clearly and completely, please refer to the following detailed descriptions with the figures and reference signs.

[0026] Refer to FIG. 1-4, a straw cup lid according to the present invention mainly includes a lid 1 and a water stopping member 2.

[0027] As shown in FIG. 1, the lid 1 is composed of a lid upper surface 11, a peripheral wall 12 integrally connected with a periphery of the lid upper surface 11 and extending downward along a central axis of the lid 1, a straw slot 13 allowing a suction port 311 on a top of a straw 31 of a cup 3 to be mounted therein and protrude therefrom, a pivot hole 14 disposed on the lid upper surface 11, and a convection hole 15 mounted on the lid upper surface 11. The lid upper surface 11 is concave downward from the periphery (where the lid upper surface 11 and the peripheral wall 12 are integrally connected) along the central axis of the lid 1 to form a depression whose central area is lower than surrounding area. The lid upper surface 11 is also concave in a radial direction of the lid 1 to form a notch on the peripheral wall 12 correspondingly and thus the straw slot 13 is defined. The convection hole 15 is penetrating the lid upper surface 11 and located adjacent to the pivot hole 14.

[0028] The water stopping member 2 consists of a pivot pin 21 protruding from a bottom surface of the water stopping member 2 and corresponding to the pivot hole 14 of the lid 1, a protruding block 22 located on the bottom surface of the water stopping member 2 and adjacent to the pivot pin 21, and a water stopping plug 23 protruding from the bottom surface of the water stopping member 2 along an axial direction of the cup 3. The pivot pin 21 is pivotally arranged into the pivot hole 14 for pivotally connecting the water stopping member 2 with the lid 1 and the water stopping member 2 can rotate around a central axis of the pivot hole 14 on the lid 1. The protruding block 22 is mounted into the convection hole 15 of the lid 1 correspondingly while the water stopping plug 23 is inserted into the suction port 311 on the top of the straw 31 of the cup 3.

[0029] In this embodiment, the straw 31 and the cup 3 are integrated into one part and the straw 31 is arranged at a peripheral wall of the cup 3.

[0030] Also refer to FIG. 3 and FIG. 4, when the cup 3 is covered with the lid 1 of the straw cup lid, the peripheral wall 12 of the lid 1 is mounted into the cup 3 and attached to an inner surface of the cup 3 tightly. At the moment, the suction port 311 on the top of the straw 31 of the cup 3 is protruding a bit from the straw slot 13 of the lid 1 while the protruding block 22 of the water stopping member 2 is mounted into the convection hole 15 of the lid 1. Thus content in the cup 3 will not flow out from the suction port 311 of the straw 31 or the convection hole 15 due to the water stopping plug 23 of the water stopping member 2 fit into the suction port 311 on the top of the straw 31 and the protruding block 22 mounted into the convection hole 15 in normal times. When users intend to drink the content in the cup 3, flip and rotate the water stopping member 2 an angle around the pivot hole 14, as shown in FIG. 5-7. When the protruding block 22 is released from the convection hole 15 and moved to abut against an upper surface of the lid upper surface 11, the water stopping member 2 is lifted so that a gap is formed between the water stopping member 2 and the lid upper surface 11 to keep the convection hole 15 open. The water stopping plug 23 of the water stopping member 2 is also released from the suction port 311 on the top of the straw 31 for allowing the user to drink the content in the cup 3 through the suction port 311 which is protruding a bit from the lid 1 and thus a more labor-saving and smooth sucking process is provided. After drinking the beverage, the water stopping member 2 is pulled and rotated to make the water stopping plug 23 return into the suction port 311 on the top of the straw 31. As to the convection hole 15 mounted on the lid upper surface 11, it is used for balancing pressure inside and outside the cup 3 while the user is sipping the content inside the cup 3 and thus the sucking process is easier and smoother.

[0031] Moreover, owing to that the lid upper surface 11 which is the depression having central area lower than surrounding area in combination with the protruding straw 31, the straw 31 is inclined to an axis of the oral cavity naturally (as shown in FIG. 7) and an ergonomic angle of the content sucked is formed for providing buffering effect and preventing the user from choking when the user closes the mouth around the suction port 311 of the straw 31 and sucks the content in the cup 3. A taste of the content (beverage) is even better.

[0032] As shown in FIG. 1, in a preferred embodiment, the convection hole 15 on the lid upper surface 11 is located within an area covered by movement of the water stopping member 2 rotated around the central axis of the pivot hole 14. That means the minimum distance H between a central axis of the pivot pin 21 and an edge of the water stopping member 2 is larger than a distance h between the central axis of the pivot hole 14 and the convection hole 15. Thereby the convection hole 15 is shielded and hidden no matter which angle the water stopping member 2 is rotated to.

[0033] Refer to FIG. 1 and FIG. 4, in a preferred embodiment, a leak-proof protrusion 231 is radially arranged at an outer surface of the water stopping plug 23. The arrangement of the leak-proof protrusion 231 makes connection between the water stopping plug 23 and an inner surface of the suction port 311 on the top of the straw 31 become closer.

[0034] In a preferred embodiment, an edge at one end of the water stopping member 2 with the water stopping plug 23 is extended outward and tilted to form a flip portion 24 for allowing the user to release the water stopping plug 23 of the water stopping member 2 from the suction port 311 easier.

[0035] In a preferred embodiment, a shield portion 25 is extended downward from a bottom surface of the flip portion 24 and attached to an outer surface of the straw 31 protruding from the straw slot 13.

[0036] Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalent.
