Apertured Sidewall (e.g., Hole, Slot, Etc.) Patents (Class 220/676)
  • Patent number: 5232120
    Abstract: A bulk shipping and storage container for liquids or dry powders comprising a rigid, round, plastic vessel, molded in one piece, and a lid for the vessel. Preferably, these parts are molded of poly(dicyclopentadiene), using the reaction injection molding (RIM) process. The lateral wall of the vessel is inclined inwardly from top to bottom so as to define an upper truncated conical section and lower truncated conical section coaxial with the upper section. The lateral wall is equipped with means for securing the lid to the top of the vessel. A recess is formed in the lateral wall of the vessel and this recess can be tapped with a threaded drainage hole to receive a threaded drain valve. The vessel's bottom is sloped towards this recess to permit complete draining of the container's contents. The container may be mounted on a pallet member or seated in a tub. Alternatively, it may be molded with an integral pallet formed by the lower portion of its lateral wall.

  • Patent number: 5145082
    Abstract: A laundry basket is disclosed, comprising four sides (4) and a bottom (5) which define an internal chamber (8). A handle opening (10) is formed in at least one of the sidewalls, proximate an upper rim (6). A handle body (12) spans the opening (10), along the rim (6). A gripping member (14) attaches to an underside of the handle body by overlapping flanges (18, 28). The gripping member (14) is upwardly concave, of relatively larger radius of curvature than the downwardly concave handle body (12). Together, the gripping member and handle body comprise a cylindrical handle assembly. The gripping member (14) is formed to provide spaced apart gripping ribs (26). Gripping ribs (26) are co-extruded with the gripping member (14), but are formed of relatively softer plastic material. Reinforcement walls (22) extend downward from the handle body (12) into the gripping member (14) and abut thereagainst for reinforcement.

  • Patent number: 5143246
    Abstract: The invention is directed to a recyclable garbage separator having an outer container and a plurality of modular inner containers adapted to be locatable within the outside container. The outside container may have pivotable cover portions having openings therein substantially corresponding to the size of the openings in the upper surface of the inner containers. The structure may be formed of recycled material and the outer container may have large openings formed in the walls thereof to reduce the weight of the container and the amount of material necessary to make the container.

  • Patent number: 5065671
    Abstract: A rigid rectangular cheese mould (1) comprising a bottom (2) and four upright walls (3) heatsealed to each other in their corners. The walls (3) are provided with outwardly diverging drainage slits (4) during injection moulding of the walls.The drainage slits (4) form rows (19) extending in the longitudinal direction of the walls, the drainage slits of one row are staggered with respect to the slits (4) of the other row.The outer side of the cheese mould (1) may be reinforced by reinforcing strips (8) or a reinforcing striplike frame.The inner surface of the wall (3) is provided with whey discharge recessions (5) forming a net structure resembling a cheese net structure comprising first structure ribs (16) and second structure ribs (17). The first ribs (16) extending in the vertical direction of the wall (3) are higher than the second ribs (17) extending in horizontal direction. The height at the intersection point is the height of the first ribs.

  • Patent number: 5011041
    Abstract: An inner surface of each of the side walls of a basket for processing thins plates is provided with plural rod-like projections extending inwardly in opposite directions to each other acting as a space holding member, a plurality of these rod-like projections are arranged in spaced apart relation along an inserting direction of the thin plates so as to form a group of rod-like projections, the groups of rod-like projections are arranged in side-by-side relation with a specified pitch for every spacing of the spaced-apart thin plates, the thin plates are inserted between adjoining groups of rod-like projections, thereby a flowing communication of the processing liquid or air is further improved as compared with the space holding member made by the continuous partition wall of the prior art, resulting in that an etching process or a centrifugal drying for the stored thin plates can be performed efficiently.
