Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a disposable cup lid which
is used for covering a cup.
[0003] 2. Description of the Prior Art
[0004] A disposable cup lid is used for covering on a cup. When the
cup is covered by the disposable cup lid, said cup lid can prevent
the content of said cup from being spilled and avoid extraneous
materials dropping into said cup.
[0005] However, a problem is often found when using the disposable
cup lid. The problem is that a user may scald when having hot
drinks with the cup lid on the cup. It's just like drinking with a
straw, so that the user's lips or tongue will directly touch hot
drinks without any buffering.
[0006] The present invention is, therefore, arisen to obviate or at
least mitigate the above mentioned disadvantages.
SUMMARY OF THE INVENTION
[0007] The main object of the present invention is to provide a
disposable cup lid for users to drink without abutting their lips
against a connection opening.
[0008] Another object of the present invention is to provide a
disposable cup lid, which is formed with a heightened hump portion
to allow the content inside of a cup to be drunk after flowing out
of the lid, and to make the fragrance of the drinks, such as
coffee, diffuse completely.
[0009] To achieve the above and other objects, a disposable cup lid
includes an engaging portion, a hump portion, a lid surface, and a
connection opening. The engaging portion is used for engaging with
a cup. At least part of the hump portion is formed annularly inside
of the engaging portion. The lid surface is connected to the hump
portion. The connection opening is defined on the lid surface, and
said connection opening is used for communicating with an interior
of the cup. The connection opening is adjacent to the hump portion.
A top of the hump portion is higher than the connection opening,
and a vertical distance from the top of the hump portion to the
connection portion is between 4 to 30 millimeters.
[0010] In other words, said hump portion and said vertical distance
allow users to have hot drinks without touching the connection
opening by their lips. In this way, hot drinks will be drunk after
flowing out of the connection opening. Thereby, unlike drinking
with a straw, the users won't scald when having hot drinks with the
cup lid on the cup. Moreover, the fragrance of the drinks can
diffuse completely, so that the drinks are much more flavorful.
[0011] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings, which show, for purpose of illustrations
only, the preferred embodiments in accordance with the present
invention.

[0016] FIG. 5 is a cross-sectional drawing of a disposable cup lid
in accordance with another preferred embodiment of the present
invention, wherein the cup lid covers a cup.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] Please refer to FIG. 1 and FIG. 2 showing a preferred
embodiment of the present invention. The disposable cup lid
includes an engaging portion 10, a hump portion 20, a lid surface
30, and a connection opening 40.
[0018] The engaging portion is used for engaging with a cup 1.
Perfectly, the engaging portion 10 has an upper wall 11 and an
outer sidewall 12. The upper wall 11 and the outer sidewall 12
respectively abut against the upper rim and the outer rim of an
engaging lip 2 of the cup 1.
[0019] At least part of the hump portion 20 is formed annularly
inside of the engaging portion 10. In present embodiment, the hump
portion 20 is generally formed as inverse V-shape with two
sidewalls 21 and 22. However, in other possible embodiments of the
present invention, the hump portion can be formed as a flange with
only one single sidewall.
[0020] The lid surface 30 is connected with the hump portion 20 so
as to cover the cup. In present embodiment, the lid surface 30 is
step-like. More specifically, the lid surface has a higher platform
portion 31 and a lower drinking portion 32. Perfectly, the drinking
portion 32 is slanted.
[0021] The connection opening 40 is defined on the lid surface 30
so as to communicate with an interior of the cup 1. Perfectly, the
connection opening 40 is defined on the slanted drinking portion
32, and said connection opening 40 is approximately located at
bottom of the lid surface 30. Thereby, it is convenient for users
to pour out the content inside of the cup 1. Further, a top of the
hump portion 20 is higher than the connection opening 40. A
vertical distance from the top of the hump portion 20 to the
connection opening 40 is between 4 to 30 millimeters.
[0022] Moreover, as shown in FIG. 3, the disposable cup lid of the
present embodiment further includes an addition opening 50. The
addition opening 50 is higher than the connection opening 40. The
addition opening 50 is provided for users to add sugar, creamer, or
other additives, so that the users can add additives without
uncovering the lid. Perfectly, a swayable covering plate 60 is
fixed on the addition opening 50. Said covering plate 60 is adapted
to selectively cover the addition opening 50, so that it can avoid
extraneous materials unexpectedly dropping into said cup. In other
possible embodiments of the present invention, another covering
plate (not shown) can be disposed near the connection opening. Said
covering plate fixed on the lid surface is swayable. Said covering
plate is adapted to selectively cover the connection opening 40, so
that it can prevent the content of the cup from being spilled and
avoid extraneous materials dropping into said cup.
[0023] Please refer to FIG. 4 and FIG. 5. In another embodiment of
the present invention, the disposable cup lid is similar to the
previous one, and said disposable cup lid further includes a
blocking plate 70. The blocking plate 70 is located between the lid
surface 30 and the hump portion 20. The connection opening 40 has a
horizontal position corresponding to the connection opening 40.
There is a height difference between the connection opening 40 and
the blocking plate 70. In other words, the blocking plate 70 will
interfere with the liquid flowing from the connection opening 40 to
a user's mouth so as to extend the flow length and the flow time of
the liquid. Thereby, the possibility of scalding is decreased and
the fragrance of the liquid can diffuse completely.
[0024] Accordingly, the disposable cup lid of the present invention
is provided with the hump portion. The hump portion, which is
formed with an appropriate spacing from its top to the connection
opening, can allow users to have hot drinks without touching said
opening directly by their lips so as to prevent from scalding.
Besides, a blocking plate can be further fixed between the
connection opening and the hump portion. The blocking plate not
only can prevent extraneous materials from dropping into the cup,
but also can increase the flow length of hot drinks to avoid
scalding. Furthermore, the present invention can allow the
fragrance of the drinks to diffuse. As a result, the drinks become
more flavorful so as to fulfill users' need.
