Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to cap for a cup.
[0003] 2. Description of the Prior Art
[0004] A conventional manner to seal a cup is using a sealing
machine to hot press a plastic film so that the plastic film
becomes sticky and adheres to the cup. Thus the user can use a
straw to pierce through the plastic film to drink the contents in
the cup.
[0005] If the contents are hot, the user may be scalded while using
the straw to drink. In order to drink the hot contents, the user
has to peel off the plastic film manually so as to drink the
contents with his/her mouth directly contacting the cup.
[0006] Another manner to seal a cup is using a cap. Some of the cup
cannot tightly seal the cup, so the plastic film can still be
additionally disposed on the cup before the cup is capped. Again,
the plastic film should be peeled off before the user drinks, which
is not convenient for the users.
[0007] The present invention is, therefore, arisen to obviate or at
least mitigate the above mentioned disadvantages.
SUMMARY OF THE INVENTION
[0008] The main object of the present invention is to provide a cap
capable of cutting a film.
[0009] To achieve the above and other objects, a cap of the present
invention is formed with an opening, which has a first side and a
second side. A pressing plate is extended from the first side
toward the second side. The pressing plate is swayable about the
first side, and the pressing plate has a distal end, from which a
cutting rim is extended downward. The cutting rim is adapted to cut
a film when the cap is in use and when the pressing plate is
pressed downward.
[0010] 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 embodiment(s) in accordance with the present
invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] Please refer to FIG. 1 to FIG. 3. A cap of the present
invention is adapted to be caped on a cup. The cap has an upper
opening surrounded by an engaging lip 5. In the first embodiment of
the present invention, the cap is formed with an opening 10, which
has a first side 11 and a second side 12. The cap further has an
engaging rim 30 formed around its periphery to engage with the
engaging lip 5 of the cup and a pressing plate 20. The pressing
plate 20 is extended from the first side 11 toward the second side
12, and the pressing plate 20 is swayable about the first side 11.
A cutting rim 21 is extended downward from the distal end of the
pressing plate 20. The cutting rim 21 is preferably integrally
formed on the pressing plate 20, and the cutting rim 21 is adapted
to cut a film. In the present embodiment, the cutting rim 21 is
V-shaped, as shown in FIG. 4. The cutting rim 21 may also be
saw-teeth-shaped as shown in FIG. 5, or it may be trapezoid and has
a slanted bottom side 211 as shown in FIG. 6.
[0022] More specifically, the opening 10 further has two lateral
opening sides 13 connecting between the first side 11 and the
second side 12 respectively. In other words, the opening 10 is
defined by the first side 11, the second side 12 and the two
lateral opening sides 13. Two blocking plates 14 are extended from
the two lateral opening sides 13 respectively. The pressing plate
20 has two lateral plate sides 22, in which the distance between
the blocking plates 14 is smaller than that between the lateral
plate sides 22. Thereby, the pressing plate 20 is blocked by the
blocking plates 14 when the pressing plate 20 is pressed downward
to squeeze through the opening 10 and does not return back to the
upper side of the opening, as shown in FIG. 7. For positioning and
forming purposes, the lateral opening sides 13 partially connect to
the lateral plate sides respectively in a disconnectable manner.
Specifically, a connecting section 15 is formed between the lateral
plate side 22 and the lateral opening side 13. The connecting
section 15 breaks when the pressing plate 20 is pressed downward.
As such, the lateral plate sides 22 disconnect from the lateral
opening sides 13. The first side 11 of the opening 10 is preferably
close to a center of the cap, and the second side 12 of the opening
10 is preferably close to the engaging rim 30. Of course, a straw
may still be used to insert through the opening once the pressing
plate 20 is pressed downward and blocked by the blocking plates
14.
[0023] In the first embodiment of the present invention, the
cutting rim 21 is used to pierce through the plastic film 6
disposed on the cup. In other words, the user can simply press the
pressing plate 20 to cut the film 6 open rather than peeling off
the plastic film 6.
[0024] Please refer to FIG. 8 to FIG. 10. In the second embodiment
of the present invention, the cap is similar to that of the prior
embodiment, expect the cap further includes a sealing film 40
disposed beneath the opening 10 to seal the opening 10. The sealing
film 40 may be a aluminum foil, a plastic film or the like to
provide the cap with better airtight property and to prevent the
contents in the cup from leaking via the opening.
[0025] In the present embodiment, no plastic film is need to be
further disposed on the cup since the cap has its own sealing film
40. The cutting rim 21 is stilled used to cut the sealing film 40
when the pressing plate 20 is pressed.
