first embodiment

[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 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.

second embodiment

[0024]Please refer to FIG. 8 to FIG. 10. In 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.

Abstract

The cap of the present invention is adapted to cap a cup. The cap 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, and the pressing plate is swayable about the first side. 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. Thereby, the user can easily drink the contents in the cup via the opening.

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, ari...
