CUP LID

Abstract

A cup lid may comprise a main body having a cup edge at an outer periphery thereof. An upper surface of the main body has a cover comprising a concave upper surface, and a first end and a second end are respectively formed at two opposed edges of the concave upper surface at corresponding positions. A concave sip portion formed adjacent to the first end, and a plane surface is formed at a bottom portion of the sip portion. A flippable sealing member extends from the plane surface, and a sip-through opening is formed overlapped with the sealing member. A month-contact portion is formed adjacent to the first end, and a height difference formed between the month-contact portion and the sip-through opening is configured to prevent the overflow of beverage when drinking.

The publications listed or discussed above, below and throughout the text are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.

[0023] In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:

[0024] Referring to FIGS. 1 to 4, the present invention provides a cup lid which comprises a main body (10) having a cup edge (11) at an outer periphery thereof. A middle portion of the cup edge (11) comprises an annular first engaging portion (111) which is an inward recess to form a ring portion (112) thereabove on the cup edge (11). Moreover, a lower portion of the cup edge (11) is formed into a guiding portion (113) which has a larger outer diameter. An upper surface of the main body (10) has a cover (12) protruding upwardly, and a lower end of the cover (12) is located lower than the ring portion (112) of the cup edge (11). Moreover, an annular locating portion (121) is formed between an outer periphery of the cover (12) and the cup edge (11), and the outer diameter of the cover (12) is gradually smaller from bottom to top to form an inclined surface (122) as an outer wall of the cover (12). Furthermore, the cover (12) has a concave upper surface, and a first end (123), a second end (124), a third end (126), and a fourth end (127) are respectively formed at four sides of the concave upper surface, wherein the first end (123) and the second end (124) are formed at two opposed edges of the cover (12) at corresponding positions while the third end (126) and the fourth end (127) are formed at the other two opposed edges of the cover (12) at corresponding positions, and a curve of the concave upper surface is formed from the first end (123) to the second end (124) to form into a concave portion (125) at the upper surface of the cover (12). Also, the first end (123) is located higher than the second end (124), and the third end (126) and the fourth end (127) are located at same height which is higher than the concave portion (125) and lower than the second end (124). Additionally, a concave sip portion (13) having a gourd-shaped cross section is formed adjacent to the first end (123), and a plane surface (131) is formed at a bottom portion of the sip portion (13) which is located lower than the concave portion (125), and a flippable sealing member (14) is extended from the plane surface (131). A sip-through opening (15) is formed overlapped with the sealing member (14) such that the sealing member (14) is configured to be flipped to unblock or block the sip-through opening (15). The sip portion (13) comprises a month-contact portion (132) which is located adjacent to the first end (123) and formed perpendicular to the plane surface (131), and a height difference formed between the month-contact portion (132) and the sip-through opening (15) is configured to prevent the overflow of beverage when drinking. Moreover, the sealing member (14) has an engaging column (141) formed adjacent to the first end (123), and a through hole (16) penetrating through a center of the cover (12) is adapted to engage with the engaging column (141) when the sealing member (14) is flipped up. In one embodiment, a flippable close piece (161) extending from an edge of the through hole (16) is adapted to be flipped to unblock or block the through hole (16).

[0025] In actual application, referring to FIG. 4, the main body (10) is covered on an upper opening (21) of a drink cup (20), and the guiding portion (113) of the cup edge (11) is disposed and coupled on the upper opening (21) of the drink cup (20); when the main body (10) is disposed on the drink cup (20), a second engaging portion (211) formed at an outer periphery of the upper opening (21) is adapted to pass through the first engaging portion (111) and to squeeze in the ring portion (112), thereby securing the main body (10) on the drink cup (20).

[0026] Referring to FIGS. 2, 5, 6 and 7, when using, the sealing member (14) is flipped upward, and the engaging column (141) is adapted to be inserted and secured in the through hole (16) of the cover (12). As a result, the sip-through opening (15) is opened to allow a user to have the beverage contained in the drink cup (20) through the mouth-contact portion (132). Moreover, with the height difference between the mouth-contact portion (132) and the sip-through opening (15), when the drink cup (20) is put down on the table by the user, the beverage in the drink cup (20) is configured to flow along the mouth-contact portion (132) back in the drink cup (20) through the sip-through opening (15). Furthermore, the outer periphery of the cover (12) is higher than the concave portion (125) such that even the outflow of beverage happens, the spilled beverage is configured to be accumulated at the concave portion (125) instead of spilling out of the main body (10). Also, a user can tilt the drink cup (20) with the main body (10) to allow the spilled beverage to flow back toward the sip portion (13), thereby avoiding spilling of beverage.

[0027] Additionally, the main body (10) is adapted to be cooperatively used with a straw (30) directly. Referring to FIG. 8, the through hole (16) located at the center of the cover (12) is adapted to be penetrated through by the straw (30) so as to allow a user to have beverage in the drink cup (20) without opening the sip-through opening (15), which increases the practicability of the cup lid.

[0028] Comparing with conventional cup lid, the present invention is advantageous because: (i) the main body (10) provides a user with two different drinking ways, which greatly improves the practicability of the cup lid; and (ii) when the outflow of beverage happens during a user drinking, the spilled beverage is accumulated at the concave portion (125) of the main body, and a user can tilt the drink cup (20) to allow the spilled beverage to flow back toward the sip portion (13), thereby avoiding spilling of beverage.

[0029] Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
