摘要： An easy-open package has a vessel forming an upwardly open compartment and having an annular rim surrounding the compartment and a foil engaging the rim of the vessel part all around the compartment, having an open tab which projects laterally past the rim, and formed with a tear line extending around the compartment except at the tab and extending around and delimiting of the tab. The tab is unitarily formed with the foil and is connected to the foil by an integral web that overlies and is bonded to the rim. The bond between the foil and the vessel is substantially weaker at the web than elsewhere.

摘要： An easy-open package comprises a vessel part forming an upwardly open compartment and having an annular rim surrounding the compartment and a foil part adhered to the rim of the vessel part all around the compartment, unitarily formed with an open tab which projects laterally past the rim, and formed with a tear line extending around the compartment except at the tab and extending to an outer periphery of the foil part to each side of the tab. One of the parts is formed as a laminate including a metal layer, a synthetic-resin layer, and a relatively weak bond securing the synthetic-resin layer to the metal layer. The synthetic-resin layer of the one part is bonded to the other part along an annular strip running around the rim with a relatively strong bond and the one part is formed in the synthetic-resin layer with at least one secondary tear line at the tab.
摘要翻译：容易打开的包装包括形成向上开口的隔室的容器部分，并且具有包围隔室的环形边缘和在隔室周围粘附到容器部分的边缘的箔部分，其整体地形成有横向突出的开口突出部并且形成有围绕隔室延伸的撕裂线，除了在突出部处并延伸到箔片部分的外周到突片的每一侧。其中一个部分形成为包括金属层，合成树脂层和将合成树脂层固定到金属层的相对弱的粘合层。一部分的合成树脂层沿着环绕带状物的环状带粘合在另一部分上，该条带具有相对较强的粘结，并且一部分在合成树脂层中形成，在该突出部处具有至少一个次级撕裂线。

摘要： In the deep-drawing of plastics films for producing containers with the aid of a plug entering into a mould and a plurality of radially movable spreading elements on the plug, it is envisaged to move the plug discontinuously during its inward movement and stop it in each case for a predetermined dwell time in its inward movement. This can be combined with a continuous or discontinuous movement of the spreading jaw elements.
