摘要： A package comprising a receptacle cup of semi-rigid plastic having a top of semi-rigid plastic sealed to flanges of the receptacle and formed inwardly to press against the packaged product and hold it in place with or without evacuation of the interior. Different techniques and apparatus are disclosed for forming such packages. Package configurations also are disclosed providing improved recloseable characteristics, wherein the semi-rigid nature of both the top and the cup are utilized to enable the reclosed top to be held securely in place.

摘要： Packaging apparatus for making vacuum or gas-filled packages of the type including a flanged cup-shaped receptacle with a closure film sealed to the flanges and stretched down into the cup to engage and press against the product. The apparatus comprises a first packaging station where the film is sealed to the cup flanges part way around the cup mouth; simultaneously the film is heated in pre-selected locations to soften it for subsequent stretching. In a subsequent station, the partially-completed package is placed in a vacuum chamber and evacuated. Thereafter, a plug is driven against the still heated film, to force it down into the cup interior adjacent the product. Before or after the plug movement, the film is fully sealed to the cup, to make a hermetically-sealed package. While the plug holds the film in its stretched condition, the spaces outside of the film are vented to apply fluid pressure to the film, to cause the film to conform closely to the product shape, and to match closely the contour of the cup.
摘要翻译：用于制造真空或气体填充的包装的包装设备，包括带凸缘的杯形容器，封闭膜密封到凸缘并向下延伸到杯中以接合和压靠产品。该装置包括第一包装站，其中膜围绕杯口部分地封闭到杯形凸缘; 同时将膜在预先选择的位置加热以软化以便随后的拉伸。在随后的站中，将部分完成的包装放置在真空室中并抽真空。此后，塞子被驱动抵靠静止加热的膜，以迫使其向下靠近产品的杯内部。在插头运动之前或之后，膜完全密封到杯子上，以形成气密密封的包装。当插头将薄膜保持在拉伸状态时，薄膜外部的空间被排出以向薄膜施加流体压力，以使薄膜紧密地与产品形状紧密并且紧密地匹配杯子的轮廓。

摘要： A sealed package comprising a cup-shaped container of relatively heavy-gauge, semi-rigid (form-retaining) plastic, with a protective member of relatively stiff material over the opening. Between the container and the protective member is a hermetic sealing closure member in the form of a relatively thin (flexible) plastic film secured around the rim of the cup. The package interior is evacuated and atmospheric pressure stretches the flexible film into the cup to engage the packaged article(s) across the full width thereof, i.e., up to the side walls of the cup. A relatively rigid and planar paper board sheet overlies the flexible film and is secured thereto by an adhesive stronger than the bond between the flexible film and the semi-rigid cup.
摘要翻译：密封包装，其包括相对较重的半刚性（保持形状）塑料的杯形容器，在开口上具有相对刚性材料的保护构件。在容器和保护构件之间是密封封闭构件，其为围绕杯边缘固定的较薄（柔性）塑料膜的形式。包装内部被抽真空，大气压将柔性膜拉伸到杯中，以使包装的物品跨越其整个宽度，即直到杯的侧壁。相对刚性和平面的纸板片覆盖在柔性膜上并且通过比柔性膜和半刚性杯之间的结合强的粘合剂固定在柔性膜上。

摘要： A packaging machine for thermoforming plastic packages, filling them with the desired contents, and sealing them under vacuum or gas if desired, wherein a train of packages move through the machine in a horizontal path at substantially constant speed, the machine including reciprocating interacting package forming and sealing elements with support means acting simultaneously on the upper and lower sides of the train of packages as they move through the machine. In an alternate arrangement, lids may be applied to package portions preformed by separate apparatus.
摘要翻译：一种用于热成型塑料包装的包装机，用所需的内容填充它们，并且如果需要，在真空或气体下密封它们，其中一串包装以基本恒定的速度在水平路径中移动通过机器，该机器包括形成的往复式相互作用的包装以及具有支撑装置的密封元件，当它们移动通过机器时，同时作用在包装列车的上侧和下侧。在替代布置中，盖可以应用于由分离的装置预先形成的包装部分。
