Description

Paper cup lid

The invention relates to a cup lid, in particular to a paper cup lid that can be buckled on the rim of the cup.

Cupd drinks sold in coffee shops, beverage shops, or vendors usually use disposable cup lids to cover the mouth of the drink cup to prevent the drink from spilling when it is moved and shaken, and to prevent external dust from falling into the drink. However, , disposable cup lids are usually made of plastic or polylactic acid, and due to the characteristics of the material, they can snap onto the rim of the cup and will not fall off easily.

However, with the rise of environmental awareness, people have begun to reduce plastic in their daily lives. Therefore, disposable cup lids made of plastic or polylactic acid may gradually be banned in the future, and other more environmentally friendly lids need to be used instead. Material.

In view of this, the main purpose of the present invention is to provide a paper cup lid that can be buckled on the rim of the cup and is not easy to fall off.

In order to achieve the above purpose, the paper cup lid provided by this new model includes: A cover member, which includes a cover surface and a coupling flange formed on the periphery of the cover surface and protruding upward; An outer ring member is combined with the coupling flange of the cover member and surrounds the outer periphery of the cover member. The outer ring member includes an outer ring wall extending downward from the cover surface. The outer ring wall has a concave ring portion and a spacing section formed between the ring portion and the cover surface.

When the paper cup lid of the present invention is placed on the mouth of the cup, the concave buckle portion of the outer ring is located below the flange of the cup rim to buckle the flange, so that the paper cup lid can be firmly buckled on the cup rim to prevent The paper cup lid fell off.

Please refer to Figures 1 to 4. The first preferred embodiment of the new paper cup cover 10 is used to cover the mouth of a cup body 20. The rim of the cup body 20 has a flange 22. The paper cup cover 10 is made of paper material and includes a cover member 11 and an outer ring member 13; both the cover member 11 and the outer ring member 13 can be cut from sheet-shaped paper materials. The mold is processed and formed, and the outer ring member 13 is combined with the outer periphery of the cover member 11 to form the paper cup cover 10; the paper material used for the paper cup cover can be the same as the paper material used for existing paper cups. , the paper can be coated with a waterproof layer on one or both sides.

The cover member 11 includes a cover surface 111 and a coupling flange 113. The coupling flange 113 is formed on the periphery of the cover surface 111 and protrudes upward. The outer ring member 13 is combined with the coupling flange 113 of the cover member 11 and surrounds the outer periphery of the cover member 11 . The outer ring member 13 includes a coupling portion 131 , an outer ring wall 133 and an outer roll. The joint part 137 covers the joint flange 113 and is combined with the joint flange 113. It can be adhered by thermal pressure.

The outer ring wall 133 extends downward from the cover surface 111 , and the outer curl portion 137 is formed at the bottom end of the outer ring wall 133 and curls outward. The outer ring wall 133 has a concave ring portion 134 and a spacing section 135 formed between the ring portion 134 and the cover surface 111 so that the position of the ring portion 134 is lower than the cover surface 111 There is a distance between the paper cup cover 111 and the cover surface 111. The length of the distance section 135 corresponds to the height of the flange 22 of the cup body 20. When the paper cup cover 10 covers the mouth of the cup body 20, the cover surface 111 abuts On the cup rim, the buckle portion 134 is located below the flange 22 of the cup body 20 and locks the flange 22 to prevent the paper cup cover 10 from falling off.
