Abstract
One embodiment of the present invention is an upper plate having an opening piece cut by pressing; A tab including a pressing portion for pressing the opening piece and a first handle portion extending from the pressing portion and having a hole; A fixing part for coupling the tab to the upper plate and supporting the pressing part to press the opening piece when the first handle is operated; And a second handle which is made of a ring having a first width and a first thickness and which is connected to the hole.
Description
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.
However, in such a can lid, since the gap between the tab and the surface of the lid is small, and the curled portion is formed so that the rim of the tab maintains rigidity, there is a disadvantage that it is difficult to fit the user's finger. Furthermore, when the user applies force to the finger and inserts the finger into the gap between the tab and the lid, the fingernail is damaged.
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.
One embodiment of the present invention is an upper plate having an opening piece cut by pressing; A tab including a pressing portion for pressing the opening piece and a first handle portion extending from the pressing portion and having a hole; A fixing part for coupling the tab to the upper plate and supporting the pressing part to press the opening piece when the first handle is operated; And a second handle which is made of a ring having a first width and a first thickness and which is connected to the hole.
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.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention and methods of achieving them will be apparent with reference to the embodiments described in detail below with reference to the drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like or corresponding components throughout the drawings, and a duplicate description thereof will be omitted .
In the following embodiments, the terms first, second, and the like are used for the purpose of distinguishing one element from another element, not the limitative meaning.
In the following examples, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.
In the following embodiments, terms such as inclusive or possessive are intended to mean that a feature, or element, described in the specification is present, and does not preclude the possibility that one or more other features or elements may be added.
In the following embodiments, when a part of a film, an area, a component or the like is on or on another part, not only the case where the part is directly on the other part but also another film, area, And the like.
In the drawings, components may be exaggerated or reduced in size for convenience of explanation. For example, the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of explanation, and thus the present invention is not necessarily limited to those shown in the drawings.
If certain embodiments are otherwise feasible, the particular process sequence may be performed differently from the sequence described. For example, two processes that are described in succession may be performed substantially concurrently, and may be performed in the reverse order of the order described.
In the following embodiments, when a film, an area, a component, or the like is referred to as being connected, not only the case where the film, the region, and the components are directly connected but also the case where other films, regions, And indirectly connected. For example, in the present specification, when a film, an area, a component, and the like are electrically connected, not only a case where a film, an area, a component, etc. are directly electrically connected but also another film, And indirectly connected electrically.
