  • Patent number: 5992628
    Abstract: Asphalt is packaged in consumable containers (10) having breakage means, such as short notches or long channels (110, 111), to allow for easy breakage into smaller portions for ease of handling and feeding into kettles. The containers are advantageously made of an asphalt-polymer composition so that the entire asphalt package may be melted in a kettle, e.g., for use in a roofing or paving application. The containers may have various features to enhance processability and handleability, including a generally rectangular shape and multi-faceted or stepped sides 20 and/or walls 30 with handhold portions and/or scooped portions.

  • Patent number: 4524882
    Abstract: The open end of a substantially cylindrical injection molded resilient plastic container, such as a paint pail, has a rim system integrally molded to the container wall to rigidify the open end of the container to facilitate filling the container using standard automatic filling equipment. An outer continuous rim and an inner discontinuous rim concentric with the outer rim are joined by a bridge member to form a substantially rigid rim system at the open end of the container.The rim system coacts with a closure lid to form a removable and resealable end closure on the container. Drainage or expulsion of fluid from between the inner and outer rims is provided for by drain openings or slots which make the inner rim discontinuous.
