Abstract

(57) [Summary] [Object] The present invention relates to a lid used to store the leftovers of canned beverage once opened in a sanitary and safe manner. [Structure] A lid attached to an opening of a can and having an annular leg which can be fitted to a top plate portion and a tightening portion of a plurality of types of cans having different diameters, respectively, and which is opposite to the top plate of the annular leg. A plurality of protruding grooves are provided on the can contact side of the side end, and a tongue-shaped piece is provided on the outer periphery of the annular leg so that the outer shape of the entire lid is in the form of a water drop. [Effect] Not only can it be used as a lid for the leftover of canned drinks of different diameters, but also when the inside pressure gradually increases with the lid covered, the lid does not blow off and a large amount of gas is generated. Even when the contents occur at once, even if the contents drink overflows without the cover being blown off, it is possible to prevent the contents drink from blowing off. Also, the tongue can raise tabs.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a lid used to store the leftovers of canned beverages once opened in a sanitary and safe manner.

[0002]

[Prior art]

 Conventionally, as a device related to a lid of a canned beverage that has been opened, a plurality of annular legs are provided so that the cans can be used for cans having different diameters, and the canned portion of the can is fitted together with the peripheral frame portion. there were. In addition, a protruding piece is provided on the outer peripheral portion of the lid, and is used for hanging on a hook.

[0003]

[Problems to be solved by the invention]

 In conventional can lids, the wound part is pressed down from inside and outside by using the elasticity of the lid material to make it difficult for the lid to come off. However, among beverages in cans that generate carbon dioxide gas in particular, even if stored at room temperature, carbon dioxide gas is gradually generated, and the lid of the can may come off due to the pressure of the gas. There is a first issue.

[0004] In addition, when the beverage in a can is overturned or subjected to strong vibration, a large amount of gas is generated at once, and the beverage inside the beverage can be blown off at the same time as the can lid is blown off. There are two issues.

[0005] A third problem is that the tab for opening the canned beverage is slightly hard, so that some force is required for the opening.

[0006]

[Means for Solving the Problems]

 The present invention includes means for solving the first problem, means for solving the second problem, and means for solving the third problem.

Means for solving the first problem include a projecting groove () on an end of the annular leg (2) opposite to the top plate (1) on the side opposite to the can contact side, which fastens the can tightening portion (6). 3) are provided at a plurality of locations to increase the fixing force of the lid, and to gradually dissipate gas from the can contact side portion where the projection groove (3) is not provided when the gas pressure in the lid increases. .

[0008] The projection groove (3) provided on the can contact side of the annular leg (2) engages with the canned portion (6) of the can to prevent the can lid from being detached from the can body. . Further, when the gas pressure in the lid becomes larger than that in the can contact side portion where the projection groove (3) is not provided, the gas can be gradually released.

Means for solving the second problem is to provide a plurality of projection grooves (3) having a length of 15 to 30 mm within a 180-degree angle of the circumference of the annular leg (2), A small protruding groove (8) having a length of 3 to 10 mm is provided at approximately the center of the degree, and when the beverage in a can falls or a strong vibration is applied and a large amount of gas is generated at once, the protruding groove (8) is generated by gas pressure. Before the 3) comes off the can body, the small projection groove (8) comes off the can body so that the entire lid of the can is tilted obliquely to the can body, so that the beverage in the can hits the top plate and does not scatter. To

In this case, since the small projection groove (8) comes off from the can body before the projection groove (3) comes off from the can body due to gas pressure, the projection groove (3) does not come off from the can body. This prevents the lid of the can from coming off the main body, so that even if a large amount of gas is generated at once, it does not blow off the lid of the can and does not spill out even if the beverage inside may overflow. can do.

Means for solving the third problem is that the tongue (4) has a rib (7) whose tip end is lower and which gets higher as it approaches the annular leg (2). Provide. To open the tab (10) of the can, insert the tip of the tongue-shaped piece (4) between the can opening surface (9) and the tab (10), and push it toward the center of the tab (10). The tab (10) can be raised.

As a material used for the lid of the present invention, a synthetic rubber or a synthetic resin having a rubber-like elasticity at around normal temperature called an elastomer is used. Examples include synthetic resins such as polyethylene, polypropylene, vinyl chloride, and polyisobutylene.

[0013]

[Effect of the invention]

 The lid of the can prepared as the first means for solving the problem according to the present invention increases the fixing force of the lid, and when the gas pressure in the lid increases, the can contact side portion where the projection groove (3) is not provided. Gas gradually escapes from the surface. Among beverages in cans that generate carbon dioxide gas in particular, even when stored at room temperature, carbon dioxide gas is gradually generated, but there is an effect that the lid of the can does not come off due to the pressure of the gas.

[0014] The can lid made in the second means for solving the problem according to the present invention has a protruding groove due to gas pressure when a large amount of gas is generated at once by overturning of the canned beverage or strong vibration. The small projection groove (8) comes off from the can body before the can comes off from the can body, so that the entire lid of the can is inclined obliquely to the can body, so that the beverage in the can does not hit the top plate portion and scatter. This prevents the lid of the can from separating from the main body, and does not blow the can lid even if a large amount of gas is generated at once, and does not spill out even if the beverage inside may overflow. effective.

[0015] In the can lid prepared in the third means for solving the problem according to the present invention, when opening the tab (10) of the can, the tip of the tongue-like piece (4) is connected to the can opening surface (9) and the tab (9). Inserting between the tabs 10) and pressing it toward the center of the tab 10 as it is has the effect that the tab 10 can be easily raised with less force than would normally be required to open the tab. You.

Further, the top plate portion (1) can be subjected to various types of printing, and can be used as an advertising medium in addition to practical effects.
