A body for a blow-molded waste cart and a waste cart having a blow-molded hollow body having a rear wall, a floor, the body and floor form a waste receptacle and a pair of axle straps integrally formed with the body. The axle straps each include a penetration with a strap bearing surface formed in penetration of the axle strap. The cart body may also include a longitudinal bearing surface with the strap bearing surface being aligned with the longitudinal bearing surface. The strap bearing surface is preferably cylindrical. A waste cart may be formed by adding an axle mounted to the body by the axle straps and wheels mounted to either end of the axle. A method of forming the carte body is also disclosed in which a pair of opposed pins are slid into the axle straps to form the axle strap bearing surfaces.

PLASTIC CONTAINER HAVING A DEEP-SET INVERTIBLE BASE AND RELATED METHODS

A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

Blow molding tools and a method of blow molding which provide that the tool have a retractable push up section in the base which allows for the article molded by the tool to have a recessed base internal to an otherwise hollow structure. As the push up is moveable, adjustment of the push up portion can be performed during an automated blow molding operation so as to allow release of the blow molded article.

Process for fastening an accessory in a blow molded plastic tank

It is proposed a process for fastening an accessory to the interior of a blow-molded tank, the tank having a plastic wall produced from a parison, the accessory comprising a body having at least one attaching portion projecting radially from the body. The process comprises the steps of: a) introducing the accessory and the parison in a molten state into a mold so that the accessory is surrounded by the parison, the mold comprising cavities, at least one cavity being equipped with at least one movable insert configured to fold locally some of the molten parison on the attaching portion; b) contacting the parison with the attaching portion; c) moving forward the insert and folding locally some of the molten parison on the attaching portion; d) closing the mold by moving the mold cavities to a final closing position and inflating the parison to form the blow-molded tank; e) moving backwards the insert; and f) opening the mold.

Molded plastic structures

A structure, such as a tabletop, may be constructed from blow-molded plastic. The tabletop may include an upper surface, a lower surface, and a hollow interior portion disposed between the upper surface and the lower surface. A lip may extend downwardly relative to the lower surface of the tabletop, and the lip including an outer surface and an inner surface. One or more supports may be disposed in the inner surface of the lip, and one or more joints may be disposed in the inner surface of the lip. A joint may be disposed between adjacent supports, and a distal portion of the lip may include a compression edge. A lower portion of the supports may contact the compression edge, and/or a lower portion of the joints may contact the compression edge.

Method and Apparatus For Forming Stretch Blow Molded Containers

The present invention relates to a base assembly (100) for forming a base portion of a plastic container. The base assembly comprises a base pedestal (104), a base mold attached to the base pedestal, a push rod (102) movable between a first position and a second position with respect to the base mold to reposition a portion of the plastic container, and an activation mechanism adapted to move the push rod between the first position and the second position.
