Filed:

Mar 30, 1990

Appl. No.:

7/502317

Inventors:

Norman C. Lee - Greensboro NC

Assignee:

Zarn, Inc. - Reidsville NC

International Classification:

B29C 4930

US Classification:

425525

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.

International Classification:

B29C 4920

US Classification:

425503

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. The bonding surfaces of the preformed insert bar members are similarly convexly arcuate to direct the plastic material of the container body to expand uniformly about the bonding surfaces for bonding thereto of a generally consistent wall thickness of the main container body.

Inventors:

Norman C. Lee - Greensboro NC

Assignee:

Zarn, Inc. - Reidsville NC

International Classification:

B65D 9100

US Classification:

220 2383

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. In a third embodiment a partition wall divides the interior container area into two collection chambers, one being provided with receptacle units and a tray for segregated recyclable collection while the other is utilizable for non-recyclable collection. A pivoted cover for the recyclable chamber enables automated inversion and dumping of the other chamber.

Appl. No.:

8/780870

Inventors:

Norman C. Lee - Greensboro NC

Assignee:

Compagnie Plastic Omnium

International Classification:

B23P 1700
B29D 700

US Classification:

29416

Abstract:

A refuse container adapted for automated dumping operation comprises a pair of side-by-side container bodies joined along a portion of their respective rims by a connecting web and rigidly integrated with one another by upper and lower lifter bars affixed transversely to each container body in disposition to be engageable by grasping members of an automated dumping apparatus. The refuse container is advantageously fabricated by a method wherein a unitary hollow container structure is blow molded to initially form the two container bodies in tandem end-to-end mirror-image relation joined by a continuous annular connecting portion. The connecting portion is partially removed at each rim, leaving the connecting web therebetween, whereby the two container bodies may be pivoted into side-by-side relation and rigidly joined by affixation of the upper and lower lifter bars. A hinged lid may be pivotably connected to the container proximate the connecting web. The lid will selectively cover either container body.
