The following statement is a full description of this invention, including the best method of performing it known to me/us:

CUP LID BACKGROUND OF THE INVENTION

1. FIELD OF THE INVENTION

[0001] The present invention relates to a cup lid and, that has a novel

drinking spout structure.

2. DESCRIPTION OF THE PRIOR ART

[0002] A lid is used to cover a cup to prevent from overflowing for

J take-away beverages.

[0003] In general, a cup lid has a drinking spout for drinking. The

drinking spout has a drinking mouth and a suitable cover piece for

covering the drinking mouth. A user can push/pull the cover piece

down/up to open the drinking mouth. The problem is that the cover piece

cannot be fixed, and the cover piece may rebound back to obstruct

drinking.

[0004] The inventor proposes a solution to the fixation problem as below.

SUMMARY OF THE INVENTION

[0005] For solving the above problem, the present invention provides a

cup lid which has a novel cover piece designed on the cup plate, configured to form a drinking mouth. The cover piece can be fixed on the plate by pushing, pulling, or pressing the cover piece.

[0006] A cup lid, comprising a lid plate and a lid body around the lid plate

to adapt to a cup, wherein the lid plate comprises a press-down part

defined by a press-down fracturing line, and a raise-up part defined by a

raise-up fracturing line, wherein the press-down part and the raise-up part

are overlapping has an overlap area. The overlap area is integrally

connected with the lid plate to form a connection part, and the open

direction of the press-down part and the raise-up part are in opposite

J direction.

[0007] When pressing the press-down part, the raise-up part is raised at

the same time, so the press-down part and the raise-up part forms a cover

piece and connected to the cup lid through the connection part, and a

drinking mouth is also formed.

[0008] In general, the width of the press-down part reduces gradually

from the open end to the connecting end, and the cover piece can be fixed

at the drinking mouth by pulling the raise-up part without additional

elements.

[0009] In another embodiment, a concave shape is designed at the closed

end of the raise-up fracturing line, so the concave shape is transformed to

be a wedge on the lid plate when pressing the press-down part.

Correspondingly, a split is disposed in the raise-up part and the split can be used to clamp the wedge. The wedge will be formed by concave U-shape and the wedge can be clamped into the line split to fix the cover piece.

[0010] In another embodiment, a split is disposed on the lid plate in rear

of the closed end of the raise-up fracturing line, When pressing the

press-down part, the raise-up part of the cover piece can be clamped into

the split.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, various embodiments of the present invention are

described with the drawings. However, the present invention can also be

widely implemented in other embodiments including any substitutions,

modifications, and equivalent changes according to the embodiments. The

scope of the patent application is defined by the claims. Many specific

details of the embodiments are provided in the specification for better

understanding, however part or all of the details in some embodiments

could be omitted for brief. The specific steps or elements should not be

J limitations of the present invention. In the drawings, the same or similar

elements are represented by the same or similar symbols. The drawings are

only used for illustration not drawn in actual size, and part of the details

can be omitted to keep the drawings concise.

[0018] A lid is used to cover a cup to prevent from overflowing for

take-away beverages. In general, the cup lid made by paper or plastic

material.

[0019] FIG. 1 is a top view of a cup lid of an embodiment. A cup lid

includes a lid plate 20 and a lid body 10 around the lid plate 20. The lid

body 10 and the lid plate 20 are formed in one-piece. The lid plate 20

contains a press-down part 301 defined by a press-down fracturing line

3011 and a raise-up part 302 defined by a raise-up fracturing line 3021.

The press-down part 301 and the raise-up part 302 are designed to have an

overlap area 40, integrally connected with the lid plate 20. The press-down part 301 can be opened downward and the raise-up part 302 are opened upward.

[0020] In this embodiment, the press-down fracturing line 3011 and the

raise-up fracturing line 3021 are made in a U shape, but it could be

arc-shaped, or the like. The open ends of the press-down part and the

raise-up part are in opposite directions.

[0021] In this embodiment, the width WI of the press-down part is wider

than the width W2 of the raise-up part, so the overlap area 40 is within the

the press-down part but outside the raise-up part, near their open ends. In

J this embodiment, the difference between the width WI and the width W2 is

4-12mm, and the overlapped length is 4-8mm, i.e., the width and length L

of the overlap area 40 are 4-12mm and 4-8mm respectively.

[0022] Figure 2 illustrates the opened state of the cup lid. If the

press-down part 301 is forced downward, the press-down fracturing line

3011 and the raise-up fracturing line 3021 are broken, the press-down part

is pushed down and the raise-up part 302 is raised up. The pressed part 301

and the raise-up part 302 form a cover piece to form a drinking mouth, and

the overlap area 40 is formed as a connection part to adhere the cover piece

on the lid plate. The user can make the cover piece perpendicular to the lid

plate 20 and pull the raise-up part 302 up to fix the pressed part 301 on the

lid plate 20 without using additional fixing structure. In another

embodiment, the width of the press-down part is gradually reduced from

the broken end to the connection end of the press-down part (from WI to

W3), wherein the width difference is 0.3~Imm, as shown in FIG. 6, so the

press-down part 301 can be easily fixed on the lid plate 20.

[0023] In one embodiment, a split 50 is set on the lid plate 20 in rear of

the closed end of the raise-up fracturing line 3021 (i.e. near the center of

the lid plate). When pressing the press-down part 301 down, the raise-up

part 302 is raised up at the same time, the press-down part 301 and the

raise-up part 302 form a cover piece and a drinking mouth. The cover piece

can be pushed back along the lid plate 20 and then clamped into the split

50 and a drinking sip 70 is formed rounded by the press-down fracturing

J line 3011, as shown in FIGS. 3 and 4. In some embodiments, both ends of

the split 50 can be extended toward the raise-up part 302 to form an elastic

area to enhance the fixation strength.

[0024] In one embodiment, the raise-up fracturing line 3021 is designed to

have a concave shape 3022 near its closed end. When pressing the

press-down part, the concave shape 3022 is transformed to a wedge 303 on

the lid plate 20. Correspondingly, a split 60 is disposed within the

raise-up part 302. The wedge 303 can be inserted into the split 60. When

pressing the press-down part 301 down, the raise-up part 302 is raised

upward at the same time. The user can fix the cover piece by clamping

the wedge 303 into the split 60, as shown as Fig. 5. In one embodiment,

both ends of the split 60 can be extended toward the wedge 303 to form an

elastic area to enhance the fixation strength.

[0025] The present invention provides a cup lid to have a wider

press-down fracturing line and a narrower raise-up fracturing line. When

pressing the area rounded by the press-down fracturing line 3011, these

two fracturing lines are broken to form a cover piece, a corresponding

drinking spout and a connection part. The width difference between the

press-down fracturing line and the raise-up fracturing line is designed to

have the functions of connection and fixation. The user can pull or push

the cover piece to fix the cover piece on the lid plate.
