    • A container ensemble for food packaging comprising a substantially planar lid member formed of a polymeric material which has a plurality of substantially planar lids which are integrally formed and separably joined to each other, each of the lids including a sealing channel around its perimeter and a skirt extending outwardly therefrom. The lid member is provided with tearable portions to facilitate separation. The other component of the ensemble is a cup member formed of a polymeric material defining a plurality of cups which are integrally formed and also separably joined to each other, the cups including a bottom, a sidewall, and a brim about an upper opening of each cup. Each cup has a skirt extending outwardly from its brim provided with tearable portions to facilitate separation. The sealing channels of the lids of the lid member are adapted to mate with the brims of the cups to provide a plurality of separably joined sealed containers when the lid member and cup member are joined in sealing engagement; the ensemble being thereby adapted for sequentially: (i) receiving serving portions of food in a plurality of cups; (ii) lidding the cups to provide sealed containers containing individual portions; (iii) separating the sealed containers; and (iv) distributing the portions.
    • 一种用于食品包装的容器集合,包括由聚合材料形成的基本上平坦的盖构件,所述盖构件具有多个基本上平坦的盖,所述多个基本上平坦的盖整体地形成并且彼此分离地接合,每个盖包括围绕其周边的密封通道和裙部 从其向外延伸。 盖构件设置有可撕裂部分以便于分离。 集合体的另一部件是由聚合物材料形成的杯形部件,所述杯状部件形成多个杯体,所述多个杯子一体形成并且彼此可分离地接合,所述杯子包括底部,侧壁和围绕每个的上部开口的边缘 杯子。 每个杯具有从其边缘向外延伸的裙部,其具有可撕裂部分以便于分离。 当盖构件和杯构件以密封接合方式接合时,盖构件的盖的密封通道适于与杯的边缘配合,以提供多个可分离地连接的密封容器; 所述组合因此顺序地适应:(i)在多个杯子中接收食物的服务部分; (ii)盖住杯子以提供包含各个部分的密封容器; (iii)分离密封容器; 和(iv)分配该部分。

    • A straw-insertable disposable lid is disclosed including a flexible disk-like body having a top surface for covering an opening of a cup, a plurality of intersecting lines of weakness each extending between two ends with the lines of weakness being located on the body and adapted to permit the insertion of a drinking straw through the top surface of the lid and a plurality of intersecting troughs for accommodating a respective one of the intersecting lines of weakness, with the troughs acting to stop the propagation of the tearing of the lines of weakness in a radially outward direction when a straw is inserted into the lid and for closing the plurality of intersecting lines of weakness in response to a fluid pressure force acting on an underside of the top surface of the lid should a filled cup incorporating such lid be inadvertently tilted over. The aforementioned lid if formed by placing a sheet of thermo-deformable material between a male and female die set, the male die including an edge for forming the plurality of intersecting lines of weakness and the plurality of intersecting troughs in a substantially planar portion of the sheet with each trough accommodating a respective one of the lines of weakness, heating the sheet of thermo-deformable material between the male and female die set and substantially simultaneously forming the plurality of lines of weakness and the plurality of troughs during the formation of the remaining portions of the straw-insertable lids.
    • 公开了一种可吸管式一次性盖,其包括具有用于覆盖杯的开口的顶表面的柔性盘状体,多个相交线的弱点,每个在两端之间延伸,其中弱线位于身体上, 适于允许吸管通过盖的顶表面插入,并且多个相交的槽用于容纳相应的一条弱化线,其中槽用于阻止薄弱线的撕裂的传播 当秸秆插入盖中时,径向向外的方向,并且响应于作用在盖的顶表面的下表面上的流体压力而闭合多个相交的弱线,如果包含这种盖的填充杯不经意地 倾斜。 如果通过将一片可热变形材料放置在阳模和阴模组之间而形成的上述盖,则阳模具包括用于形成多个相交线弱点的边缘和多个相交槽中的多个相交槽 每个槽容纳相应的一条弱线,在阳模和阴模组之间加热可热变形材料片,并且在形成剩余的时候基本上同时形成多条弱线和多个槽 部分可吸管盖。
