    • Several improved manhole grade rings and methods for providing improved manhole grade rings. In one embodiment, a plurality of concentric annular rings are connected by radial ribs. Certain radial ribs can be broken to provide a manhole grade ring of the desired diameter. In several other embodiments, concentric annular ribs and interconnecting radial ribs provide lightweight stackable manhole grade rings. In another embodiment, a manhole grade ring defines an annular cavity that can be filled to reinforce the manhole grade ring. Two embodiments provide improved forms for pouring manhole grade rings in place. One form provides a plurality of forms of different diameters that can be filled to any height, while another form provides adjustable height of the manhole grade ring.
    • 几个改进的井眼等级环和提供改进的井眼等级环的方法。 在一个实施例中,多个同心圆环通过径向肋连接。 可以破坏某些径向肋,以提供具有所需直径的井眼级环。 在其他几个实施例中,同心环形肋和相互连接的径向肋提供轻量级的可堆叠人孔等级环。 在另一个实施例中,人孔等级环限定可填充以加强井眼等级环的环形空腔。 两个实施例提供用于将人孔等级环倾倒到位的改进形式。 一种形式提供可以填充到任何高度的不同直径的多种形式,而另一种形式提供了人孔等级环的可调高度。

    • A molded display tray and lid includes a generally planar base from which a pair of end walls and a pair of side walls extend generally perpendicularly. A downwardly extending lip extends about the periphery of the upper edge of the side walls and end walls. The side walls each include an upper edge that curves downwardly towards its center, such that the center of each side wall is the lowest point of the side wall. The base includes a plurality of integrally molded, downwardly extending feet. In use, the display tray and lid is first used as a lid on a box of produce, such as bananas. At its destination, the box and lid are inverted, and the box removed, such that the contents are left remaining on the display tray and lid.
    • 模制展示托盘和盖子包括大致平面的基座,一对端壁和一对侧壁大致垂直延伸。 向下延伸的唇缘围绕侧壁和端壁的上边缘的周边延伸。 侧壁各自包括朝向其中心向下弯曲的上边缘,使得每个侧壁的中心是侧壁的最低点。 底座包括多个整体模制的向下延伸的脚。 在使用中,显示盘和盖子首先用作一盒产品(如香蕉)上的盖子。 在其目的地,盒子和盖子被倒置,并且盒子被移除,使得内容物留在显示盘和盖子上。
