| 20080244988 | MANHOLE GRADE RING - 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. | 10-09-2008 |
| 20090107998 | CONTAINER - A plurality of containers and system and method for making a plurality of different containers from a minimum number of molds, with some inserts, provides multiple container sizes from the same mold utilizing inserts to reduce the size of the mold. In one embodiment, to accommodate various lid designs, a rim is connected to the upper edge of the container. The rim can be formed in various configurations from a single mold using mold inserts. The various rim configurations accommodate different lids. Providing the mold inserts on the rim (which is a very shallow part) is much simpler than providing such inserts on the container itself. | 04-30-2009 |
| 20100037565 | MEDICAL WASTE CONTAINER LID - The present invention provides a lid for a waste container having a first portion pivotably connected to a second portion. The first portion includes a first handle and a first protrusion and the second portion includes a second handle and a second protrusion. The first protrusion engages the second protrusion to prevent the first portion from rotating relative to the second portion past a threshold angle. | 02-18-2010 |
| 20100108675 | MEDICAL WASTE CONTAINER - In one example of the present invention, a medical waste container assembly includes a container having a base portion and an upper edge and a secondary lid located adjacent the upper edge of the container having a door hingeably attached to the secondary lid with the door being trimmed from a portion of the secondary lid. | 05-06-2010 |
| 20100132311 | CRATE FOR CONTAINERS - A crate includes a bottom wall including a plurality of dividers defining a plurality of container pockets and a peripheral wall extending upward from a periphery of the bottom wall. The bottom wall and peripheral wall are thermoformed from a single sheet of plastic, such as recycled PET bottles. | 06-03-2010 |
| 20100326871 | TRAY - A tray for bakery items includes a floor and side walls extending around a periphery of the floor. The tray has a relatively thin upper edge with a bail member pivotably attached to the upper edge along at least one of the first and second pairs of side walls. The bail member is rotatable between a stack orientation wherein a like tray may be rested upon the bail member, and a nest orientation in which like trays may be nested within like trays. Further, one or more side walls also includes a relatively large continuous opening therein capable of retrieving bakery items stored in the tray through the at least one pair of side walls, the opening extending generally from the upper edge to the periphery of the floor. In another embodiment, at least one of the sidewalls is pivotably attached to the floor and is movable between an upright position and a collapsed position. | 12-30-2010 |
| 20110024430 | REUSABLE WASTE CONTAINER - A reusable biohazard waste container is configured such that the container can be transported without requiring any additional packaging elements. A lid is pivotally connected to the container and is movable between an open position and a closed position. A latch secures the lid to the container when in the closed position such that the container is capable of holding liquids. | 02-03-2011 |
| 20110062161 | ATTACHED LID CONTAINER WITH BAG RETENTION FEATURES - A container includes a base wall and a pair of opposed side walls extending upward from side edges of the base wall. A first end wall and a second end wall extend upward from end edges of the base wall. A lid is hingeably connected to each of the side walls. A first protrusion protrudes from an upper edge of the first end wall for hooking onto a bag in the container. | 03-17-2011 |
