Abstract: An apparatus is disclosed for collection of refuse comprising a container body defining an interior receiving area and having a first end defining an access opening into the interior receiving area. A second end of the container body is closed and has a region which is exposed to excessive wear during use. The container also has at least one wear resistent element removably and replaceably attached to the container body over at least a portion of the wear region to form a primary wear surface, thereby protecting the wear region and extending the useful life of the apparatus. The wear resistent element may be formed of plastic and may be a glass filled nylon plastic. The second end of the container body may have a corner with the wear region comprising the corner. The wear resistent element may be attached to the container body adjacent the corner.

Abstract: An apparatus for the collection of refuse including a wheeled container having an interior compartment which can be covered by a removable lid, the lid being held in place by pivoting handles, the handles being limited in their pivoting movement by stop members for enhanced control during tipping and rolling movement of the container.

Abstract: Blow molding apparatus for producing an article including compression rings or other compression molded areas utilizes mold halves each having multiple mold sections connected in end-to-end relation by a series of guide rods having end stops to permit limited movement of the mold sections toward and away from one another. With the present control rod arrangement, only a single actuating arrangement is necessary to accomplish the formation of multiple compression molded areas.

Abstract: A nestable plastic trash container having integrally bonded upper and lower plastic lifter bar members for automated dumping operation by conventional semi-automatic dumping apparatus is fabricated by initially preforming the lifter bar members by blow molding, inserting the preformed lifter bar members into respective recesses in another blow mold apparatus for forming the main body of the container, and then blow molding the main container body while simultaneously bonding it to the preformed lifter bar members. The insert-receiving recesses of the container body blow mold apparatus and the preformed lifter bar members respectively have compatible end-to-end convex arcuate surfaces which abut in sealing relation during the blow molding of the container body to prevent escape of the plastic material into the insert-receiving recesses.

Abstract: A refuse collection apparatus for segregation of recyclable materials and the like includes an outer container body which receives a plurality of inner complimentary receptacle units. Each receptacle unit includes recessed handle members at the upper edge thereof to facilitate removal from the outer container and a lower handle portion at the opposite end of the unit for convenient carrying and dumping of the unit. In one embodiment, a wire support frame is fitted within the rim of the outer container body to support lip portions of the receptacle units. In another embodiment, a receptacle tray is provided to rest within the container body on the receptacle units for collecting stackable recyclable materials such as newspaper, while only partially covering the access openings to the receptacle units for permitting deposit of refuse therein without removing the tray.

Abstract: A plant container with concavoconvex ribs for growing plants and the like which is characterized by its ability to easily prevent the soil medium in the container from collapsing into a hole which has been mechanically drilled into the soil medium in order that a plant may be inserted into the medium, by its ability to be easily nested, by its ability to be efficiently and comfortably handled, and by its ability to be easily drained with maintenance of an optimum water level. The plant container is readily adaptable for use with a variety of plants and includes a frusto conical body made of molded plastic and has a rim portion at the top and a base portion at the bottom. The sidewalls of the container consist substantially of concavoconvex ribs that are concave on the inside sidewall and convex on the outside sidewall. Additionally, the bottom of the plant container contains one or more channels that extend radially across the bottom of the plant container.

Abstract: A planter and reservoir combination in which the reservoir is integrally molded at the bottom of the planter to support a plant supporting base.
