摘要： The method provides for heating a food package by boiling wherein between the lid and the tray a liquid-tight mechanical connection is provided, plus a gas-tight meltable seal. In heating under water the seal melts and allows the escape of steam from the interior while the mechanical connection maintains the interior free of indrawn water.

摘要： A laminated or multi-wall carton or tray is provided which has a self-supporting outer layer or wall portion of paperboard which is a laminated structure, and includes a paperboard with a plastic or foil layer adhered or laminated thereto. The laminated layer of material may be on one or both sides of the paperboard adhered to the surface, preferably before the tray or carton is die cut and formed into a tray or carton. This laminated structure or paperboard outer wall of the carton or tray is an independent self-supporting unit during the manufacture of the laminated tray or carton though it is not sufficiently strong to form a carton or tray by itself. A plastic liner is thermovacuumformed into the paperboard tray or carton in contact with the lamination on the paperboard therein to provide a boilable bakeable liquid-tight leakproof lining for the tray. The strengthened carton structure in outer paperboard supporting structure coated with a plastic or foil film heat resistant at baking temperatures and an inner plastic film or liner for contact with the food if food is the product being packaged. A laminated or multilayer wall tray or carton is provided with a corner construction to resist leaking of vacuumized containers for example, and to form a simple stop for use in nesting of the cartons.
摘要翻译：提供层叠或多壁纸箱或托盘，其具有作为层压结构的纸板的自支撑外层或壁部分，并且包括具有粘合或层压在其上的塑料或箔层的纸板。层压材料层可以在纸板的一侧或两侧粘附在表面上，优选在托盘或纸箱被切割并形成托盘或纸箱之前。纸板箱或纸盘的层压结构或纸板外壁在层压托盘或纸箱的制造过程中是独立的自支撑单元，尽管它本身不能形成纸箱或托盘不够牢固。塑料衬垫被热真空成型到纸板托盘或纸板箱中，与纸板上的层压体接触，以提供用于托盘的可煮沸的可液封的液密防漏衬里。外部纸板支撑结构中加强的纸箱结构涂覆有在烘烤温度下耐热的塑料或箔膜，以及用于与食品接触的内部塑料膜或衬垫，如果食品是包装的产品。

摘要： A laminated or multi-layer wall tray is provided which has a self-supporting outer layer or wall portion of paperboard which can be formed and handled as an independent self-supporting unit during manufacture of the laminated tray. A plastic liner is heat-vacuum formed into the paperboard tray or carton to provide a boilable, bakeable, liquid-tight, leakproof lining for the tray which in its entirety is of a boilable or bakeable character, and to provide a strengthened structure of the composite tray of the outer paperboard supporting structure and inner plastic film liner in supporting structure. Both the liner and the paperboard are preferably made of a thinness or caliper of a dimension less than can be normally employed in such structures when used alone. At the bottom the paperboard outer structure has certain formed indents around its bottom corner edge which provide resting portions or stops for nesting of the tapered trays to be handled as a stack, and also provide exit openings or vents for air from within the carton or tray at required positions to the outside during the thermo-vacuum forming of the liner. The method of fabricating or combining the components of such a tray comprises the steps of forming the outer paperboard structure or layer with the corners locked or secured together in self-supporting fashion to receive the plastic liner by thermo-vacuum forming process drawn inside of the self supported paperboard outer structure to correspond identically to the inner profile of the paperboard container thereby locking and if desired, adhering the molten plastic material to the inside paperboard structure. A laterally horizontally extending flange may be provided around the upper edge of either the paperboard or the plastic, or both.
摘要翻译：提供层叠或多层壁托盘，其具有自支撑外层或纸板的壁部分，其可以在制造层压托盘期间作为独立的自支撑单元形成和处理。塑料衬垫被热真空地形成在纸板托盘或纸箱中以提供用于托盘的可煮沸，可烘烤，液密的防漏衬里，其整体上具有可煮沸或可烘烤的特性，并且提供加强的结构外部纸板支撑结构的复合托盘和支撑结构中的内塑料薄膜衬垫。衬垫和纸板都优选由尺寸小于在单独使用时在这种结构中通常使用的尺寸的厚度或厚度制成。在底部，纸板外部结构在其底部角边缘周围具有一定的成形凹痕，其提供用于嵌套作为堆叠处理的锥形托盘的搁置部分或止动件，并且还为纸箱或托盘内的空气提供出口或通风口在衬套的热真空成形期间到达外部的所需位置。制造或组合这种托盘的部件的方法包括形成外部纸板结构或层的步骤，其中角部以自支撑方式被锁定或固定在一起，以通过在真空成形过程中绘制的热真空成形工艺接收塑料衬套自支撑纸板外部结构与纸板容器的内部轮廓相同地对应，从而锁定，并且如果需要，将熔融的塑料材料粘附到内部纸板结构。可以围绕纸板或塑料的上边缘或两者设置横向水平延伸的凸缘。

摘要： The carton and package provide a heat-releasable connection for a closure for a package which is to be heated for use wherein the heat sealed connection will become ineffective when subjected to boiling water conditions. In one form, the closure is a lid for a tray type container. In the second form the closure is a small closure for a small aperture in the lid wherein the size of the aperture is such that it will act as a one-way valve when the package is heated underneath the surface of the water to allow escape of steam or vapor under pressure and to prevent the ingress of water.
摘要翻译：纸箱和包装为用于要加热的包装的封闭件提供可热释放的连接，其中当经受沸水条件时，热密封连接将变得无效。在一种形式中，封闭件是托盘型容器的盖子。在第二形式中，封闭件是用于盖子中的小孔的小封闭件，其中孔的尺寸使得当包装被加热到水表面下方时，其将用作单向阀，以允许蒸汽或蒸汽在压力下，并防止水进入。
