Embodiments of the present invention relate to a can lid.

In general, a can is a hermetically sealed container for storing contents of various beverages and foods for a long period of time, and is manufactured variously from aluminum alloy, steel and the like. Such can is classified into a type that opens the entire body according to the opening structure of the lid provided at the upper portion of the body and a type that separates and opens a part of the body. The type that opens the whole is called a one-touch can, and is mainly applied to food storage. In the case of a type in which a part is opened, a tab is provided which can open an opening formed in a part of the lid, and the opening is designed in a size suitable for the outflow of liquid.

Conventional beverage cans are made of a thin metal plate and have a body in a form suitable for accommodating liquid contents (carbonated beverages, beer, etc.), and a lid sealingly connected to the upper portion of the body and sealing the lid. An opening piece is formed in the lid, through which a part is opened through a perforated line. Further, the lid is provided with a tab for pressing and opening the opening piece in the downward direction. In the conventional can, when the tab is lifted upward, the front portion of the tab is moved downward to press the opening piece according to the principle of the lever.

Embodiments of the present invention solve this problem and provide a can lid that can facilitate the opening operation of the lid by including the second handle that is connected to the first lid of the tab.

In one embodiment of the present invention, the second handle includes at least one first ramp disposed on an outer circumferential surface of the ring, wherein the first ramp has a second thickness ranging from a first thickness to a second thickness In the first direction.

In one embodiment of the present invention, the first width may be less than the second thickness.

In one embodiment of the present invention, the second handle is disposed on an outer circumferential surface of the ring, wherein a thickness along a second direction opposite to the first direction is sequentially from the first thickness to the second thickness May further include one or more second inclined portions.

In one embodiment of the present invention, the second handle may be alternately disposed along the outer circumferential surface of the first inclined portion and the second inclined portion.

In one embodiment of the present invention, the portable terminal may further include an auxiliary handle connected to the second handle.

Other aspects, features, and advantages will become apparent from the following drawings, claims, and detailed description of the invention.

The can lid according to the embodiments of the present invention includes the second handle portion and includes the first inclined portion whose thickness gradually increases in the second handle portion so that the first handle portion of the tab is easily lifted from the upper plate, So that it can be easily opened.
