    摘要： An egg carton molded of flexible material having a bottom with two generally parallel rows of egg pockets and upwardly tapering posts interspersed between the egg pockets, and having a cover with a generally flat top and depending side walls adapted to overlie the bottom in the closed carton condition. The cover includes three downwardly recessed window wells, each having four downwardly and inwardly flaring planar separator segments spaced from each other to define four open egg viewing windows. The generally flat top of the cover not occupied by the window wells, or by downwardly tapering support posts, is yieldable to permit slight tilting flexure of each window well, and the separator segments are also yieldable to permit laterally shifting flexure of each window well. The flexibility of the window wells permits minor yielding or adjustment to accommodate for variations in spacings between the eggs packaged in the carton to maximize visibility of the eggs and at the same time minimize the danger of damaging them.

    摘要翻译： 由柔性材料模制的蛋纸箱，其底部具有两个大体上平行的蛋袋，并且分布在蛋袋之间的向上锥形的支柱，并且具有盖，其具有适于覆盖封闭纸箱中的底部的大致平坦的顶部和悬挂侧壁 条件。 盖子包括三个向下凹入的窗口孔，每个具有四个向下和向内扩张的平面分离器段，彼此间隔开以限定四个开放的鸡蛋观察窗。 盖子的大致平坦的顶部没有被窗口孔占据，或者通过向下锥形的支撑柱可屈服，以允许每个窗户井的轻微的倾斜挠曲，并且分离器段也是可屈服的，以允许每个窗口的横向偏移弯曲。 窗口孔的灵活性允许轻微的屈服或调整以适应包装在纸箱中的蛋之间的间隔的变化，以最大限度地提高鸡蛋的可见度，并同时最小化损害它们的危险。

    摘要： Unitary molded packaging tray carries individual portion cups and is nestable with tray of like configuration. Tray comprises substantially flat bottom wall with upwardly and outwardly flaring side wall extending from bottom wall. Individual compartments are constructed and arranged to receive portion cups, each compartment having bottom portion with spaced apart plateaus raised therefrom for supporting portion cup above bottom portion of compartment. At least one broad flat bottom wall segment extends between each adjacent pair of compartments and is contiguous with bottom portions thereof so that when trays filled with portion cups are stacked one above the other broad flat bottom wall segments of upper tray in stack rest upon outer periphery of portion cups in tray directly therebelow in stack.

    摘要： A method of coating a contoured portion of a generally porous molded pulp article having sloping side and flat bottom wall portions with generally imperforate thermoplastic material to achieve a superior bonded product. First the article to be coated is placed against an open-face suction die, a flat continuous sheet of thermoplastic material is then placed in overlying relationship with the exposed portion of the die-supported article, the temperature of the thermoplastic material is raised to the range where it is sufficiently ductile to closely conform with the contoured portion of the molded pulp article, the thermoplastic material is suction adhered into intimate physical contact with the article without undesireable pleats or folds, a closed chamber is created around the article and its adhered thermoplastic material with the open-face suction die forming a portion thereof, the pressure within the closed chamber is increased to act against the exposed portion of the thermoplastic material with a pressure at least twice atmospheric pressure, and finally the temperature of the thermoplastic material continues to be raised until a mechanical bond with the contacted pulp is effected which is characterized in the finished product by a substantially uniform penetration of thermoplastic material into the adjacent pulp material on the sloping side as well as the flat bottom wall portions and the penetration of fibrous pulp material into the adjacent side of the thermoplastic material is also substantially uniform as to both quantity and depth of penetration on the side as well as the bottom wall portions so that a substantially equal amount of force is required to forceably separate the thermoplastic as a sheet from a given area of the bottom wall portions and from a given area of the side wall portions, and so that a substantially uniform amount of pulp material per area unit adheres to the thermoplastic material from the side as well as the bottom wall portions at any place over the bonded surface of the thermoplastic material when it is forceably separated as a sheet from the remainder of the product.
