摘要： The present invention relates to a method for producing a re-closable container which comprises a container body (1) and a closure lid (2). The container body (1) has an outwardly directed peripheral flange (5) and the lid (2) a peripheral frame member (9) which is separated from this peripheral flange (5) by a discontinuous die-cut line (12). The container body (1) and the peripheral frame member (9) do therefore not have to be injection moulded but can also be thermoformed in one piece. A lidding film (10) is sealed on the upper surface (6) of the peripheral flange (5) and on the upper surface (11) of the peripheral frame member (9). During the sealing step the bridging elements (13) of the discontinuous die-cut line (12) are broken by displacing the peripheral frame member (9) by means of the seal tool to a lower level than the peripheral flange (5). When opening the container, the lidding film (10) is peeled off from the container body (1) but stays adhered to the peripheral frame member (9) of the lid (2). The container can easily be opened since the bridging elements (13) between the lid (2) and the container body (1) are broken during the heat sealing step.
摘要翻译：本发明涉及一种包括容器主体（1）和封闭盖（2）的可重复封闭容器的制造方法。容器主体（1）具有向外的周向凸缘（5）和盖（2）周边框架构件（9），该外围框架构件（9）通过不连续的模切线（12）与该周边凸缘（5）分离。因此，容器主体（1）和周边框架构件（9）不必进行注塑，而是可以一体成型。封盖膜（10）密封在周边凸缘（5）的上表面（6）和周边框架构件（9）的上表面（11）上。在密封步骤期间，不连续冲切线（12）的桥接元件（13）通过借助于密封工具将外围框架构件（9）移位到比周边凸缘（5）更低的水平而被破坏。当打开容器时，封盖膜（10）从容器主体（1）剥离，但是保持粘附到盖（2）的周边框架构件（9）上。容器可以容易地打开，因为盖子（2）和容器主体（1）之间的桥接元件（13）在热封步骤期间被破坏。

摘要： Equipment (24) for producing a component (6) obtained from two sheets (10, 12) of thermoplastic material joined together comprises an upper die (26), a lower die (28) and means (38) for delivering a compressed jet of air between the two sheets (10, 12). The equipment (24) further comprises a slide (34) which can move at right angles to the closure direction of the two dies (26, 28) and has a working surface (36) which connects two working surfaces (30, 32) of the upper die (26) and the lower die (28) to one another. In use, the two sheets (10, 12) are urged against a shaping surface formed by the working surfaces (30, 32, 36) of the upper and lower dies (26, 28) and of the slide (34) by the effect of the delivery of compressed air.

摘要： The invention provides a method of making an article, e.g. a tray, from sheet material (7) such as thermoplastics, whereby sharp edges are avoided, comprising the step of deforming the sheet to form the article (3) with a marginal flange (5) having a down-turned lip (6), and cutting the article from the sheet to form a cut edge (12) at the extremity of the down-turned lip, and characterised by the steps of forming the down-turned lip (6) with an inwardly projecting recess or depression (10) extending lengthwise of the lip (6), and crimping the down-turned lip to form a folded or rounded corner (11) in the down-turned lip and to bring the cut edge (12) into the vicinity of the folded or rounded corner to form a finished edge (11, 12). From another aspect the invention is a forming tool for finishing or rolling the edge (12) of an article (3) of the kind referred to above characterised by means (2) for engaging the lip (6) and cutting the article (3) from the sheet (7) and by means (1, 4) for engaging and crimping the down-turned lip (6) to form a folded or rounded corner (11) in the lip and to bring the cut edge (12) into the vicinity of the folded or rounded corner to form a finished edge (11, 12).

摘要： A multiwalled plastic container (10) and method for making the same having a barrier liner (28) and an outer wall (14) providing ctructural support for the liner. The container provides increased protection against separation of the liner and structural wall (12) especially at the rim (26) defining the opening (22) of the container. This is accomplished by a wrap-around liner construction (32) wherein the liner extends from the inside surface (38) of the structural wall (14) around the top rim surface of the wall and downwardly depends therefrom along the outer surface of the structural wall. The downwardly-depending leg (44) of the liner lip (32) is recessed within the outer wall surface providing added protection against liner separation.

摘要： A method of manufacturing a plastic container having a curled rim (320) comprises the steps of providing a sheet of plastic material; drawing a portion thereof into a mould (120) to form a bottom and wall (310′) of the container, leaving a surrounding portion of material to form a rim (320) of the container; cutting the rim loose from a remaining portion of material; and curling the rim. In the curling step, an inner part of the rim is supported by a supporting member while an outer part is pressed by a pressing member (230) moving relative to the supporting member for the rim to be bent around the supporting member.
