    • The invention comprises a soda can lid which forms a seal with one's upper lip during thereby preventing spillage and eliminating residue. The raised platform area on the lid is connected to the pull-tab area with outwardly sloping walls designed to engage the lips. The platform area is slightly higher than the depth of a circular peripheral groove ranging up to slightly higher than the rim. The lid may also include seal portions extending upwardly from the platform on both sides of the depressed pull-tab area. The invention may be employed on lids either with or without a peripheral groove. Another feature of the invention is a pull-tab with an arch handle and special puncture tip for easier more comfortable use by consumers.

    • This invention comprises a sanitary beverage can lid wherein the center platform of the lid including the pull tab is raised from below the rim of the can as in conventional cans to a position close to or slightly above the rim of the can. The center platform diameter is reduced in diameter to provide additional space from the exterior of the can body to the edge of the platform. The pull tab is positioned in the middle of the center platform so that the end of the pull tab is at the edge of the center platform to facilitate opening of the can. The raised center platform and the lid design prevent an individual's lip from coming in contact with the groove along the edge of the lid where dirt may accumulate. Another feature is the provision of a raised rim on the platform with an interior drain-back slope so that any excess beverage flows back into the can.
    • 本发明包括一种卫生饮料罐盖,其中包括拉片的盖的中心平台如在常规罐中从罐边缘的下方升高到接近或略高于罐边缘的位置。 中心平台直径减小直径,以便从罐体的外部到平台的边缘提供额外的空间。 拉片定位在中心平台的中间,使得拉片的端部位于中心平台的边缘以便于打开罐体。 凸起的中心平台和盖子设计防止个人的唇缘沿着盖子边缘与凹槽接触,污垢可能积聚。 另一个特征是在平台上设有一个凸起的边缘,并具有一个内部排水回坡,使得任何多余的饮料流回到罐中。

    • A beverage can lid comprises an outer peripheral groove adjacent the outer rim and an inner concentric groove separated therefrom by a dividing rim which is at a predetermined height relative to the outer rim. A center platform is connected to the dividing rim by walls which slope downwardly from said rim. The central pull tab area is approximately the same height as the height of the inner groove and is connected to the inner dividing rim at one end with an upwardly curving surface. The outer groove which may be shallow and permits entry of a crimping tool to mount the lid on a can is also easily cleaned to provide a sanitary can lid. The inner groove may be blocked in the pouring spout area to facilitate cleaning.
    • 饮料罐盖包括邻近外边缘的外周槽和通过相对于外边缘处于预定高度的分隔边缘与其分开的内同心凹槽。 中心平台通过从所述边缘向下倾斜的壁连接到分隔边缘。 中央拉片区域与内槽的高度大致相同的高度,并且在一端具有向上弯曲的表面连接到内分隔边缘。 外槽可以是较浅的并且允许压接工具进入以将盖安装在罐上的外槽也容易清洁以提供卫生罐盖。 内凹槽可能在倾倒口区域被阻塞,以便于清洁。
