Benefits of technology

[0009]The main object of the present invention is to provide a lid which is able to cover and engage a cup stably.

Problems solved by technology

However, the cup or the rim flange may be deformed when the cup is grabbed by someone.
However, engagement of the lid provided in U.S. Pat. No. 5,538,154 is so firm that user can hardly remove the lid when he / she wants to.
Consequently, the projecting tab would complicate the lid making the lid difficult to be produced, and the cutting line would damage structure of the lid making the lid fractured once the lid is removed.

Embodiment Construction

[0023]Please refer to FIG. 1 to FIG. 3 for a first embodiment of the present invention. The lid of the present embodiment is provided for covering and engaging a cup 10. The cup 10 has a body 11 and a rim flange 12. The body 11 is formed cylindrically with an upper opening. The rim flange 12 is disposed on the body and surrounds the upper opening annularly. The cup 10 may be made of paper, plastic, or other suitable material.

[0024]In the present embodiment, the lid includes a top portion 20, an annular side plate 30, and three engagement portions.

[0025]The top portion 20 is adapted for covering upon the rim flange 12 and covering the upper opening of the cup 10. The top portion 20 may be formed with suitable grooves, protrusions, or openings for user to drink directly or to drink with a straw. Preferably, the top portion 20 is formed with an additional annular inner plate 21 extending downwardly therefrom. The inner plate 21 is adapted for abutting against inner surface of the cup 1...

Abstract

A lid of the present invention is provided for covering or sealing a cup by engaging a rim flange of the cup. The lid includes a top portion and an annular side plate which extends downwardly from periphery of the top portion. The plate is formed with a hole. An engagement plate is disposed on the side plate. A bottom edge of the engagement plate is connected to the plate. A top edge of the engagement plate stretches upwardly along the hole, so that the engagement plate is located in the hole. The plates are flexible. As such, the engagement plate can be pressed and bent inwardly when the lid covers a cup. The engagement plate would then engage with the rim flange of the cup so as to enhance engagement of the lid and the cup.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a lid utilized for covering a cup.[0003]2. Description of the Prior Art[0004]Conventional lid is prepared with annular inner protruding portion at lower periphery thereof. The protruding portion is able to abut against annular rim flange of a cup.[0005]However, the cup or the rim flange may be deformed when the cup is grabbed by someone. As a result, the cup is probably dropped out from the protruding portion. Moreover, each batch of cups has its own particular specifications established by the suppliers. The standards for the size, the thickness, the height, and the diameter of the rim flanges of cups are different from provider to provider. If the lid is not fit well with the cup, the cup can be dropped out from the lid easily.[0006]To enhance engagement of the lid and the cup, lid, as disclosed in U.S. Pat. No. 5,538,154, is provided with inwardly extending panels which functions as b...
