  • Publication number: 20080264954
    Abstract: The invention includes a novel profile for a container bottom. The bottom structure includes a domed central panel attached at its outside edge to a downwardly projecting substantially cylindrical inner leg portion. The inner leg portion is attached to a generally semi-circular nose portion. The outside of the nose portion is attached to an upwardly and outwardly inclined outer leg portion. The outer leg portion is attached to an outwardly inclined peripheral portion. The peripheral portion is attached to the lower end of the generally cylindrical sidewall portion. The improvement primarily involves the larger stand diameter, and altered dome circle radius and dome depth, which produces a container bottom profile yielding more consistent results in drop tests to determine resistance to bulging and reversals (single can and consumer package flat and angled drop tests) than prior art can bottoms.

  • Patent number: 7441672
    Abstract: A produce packaging container having an arched bottom surface and raised feet is described herein. The containers each can include upper ventilation slots and lower ventilation channels. The lower ventilation channels are formed by arching the bottoms of the baskets to form cooling flow channels that direct cool air under the bottoms of the containers. Raised supports enable bi-directional cooling airflow to pass underneath the baskets in at least two transverse directions. Bi-directional airflow is also achieved in the upper portion of the baskets through the ventilation slots.

  • Patent number: 7093722
    Abstract: The invention provides devices and methods for removing and trapping large and/or dense abrasive particles from a polishing slurry. The polishing slurry is introduced into a container and allowed to stagnate, thereby causing large and/or dense particles to separate from the slurry under the influence of gravity. The container includes a cavity or plurality of cavities defined by an inner surface of the container into which the separated particles sink. To prevent the large and/or dense particles from becoming re-suspended into the slurry, the size and shape of the cavity is relatively deep and narrow with respect to the large and/or dense particles, thus providing a trapping effect. The cavities do not effectively trap the smaller particles.

The bottle has a noncircular cross-sectional configuration with corresponding major and minor axes. The mold-base region of the bottle mold-cavity features at least one standing rib-like projection generally parallel to the major axis. The standing rib-like projection increases surface distance in a direction generally corresponding with the minor axis. An expanding heated preform traverses the increased surface distance causing the preform to thin more than what otherwise would be the case thus improving material thickness distribution of the base portion that in turn minimizes unwanted bottle shape distortions.

  • Patent number: 6644494
    Abstract: A hinged container includes a basket having a base, a pair of sidewalls, and a pair of endwalls. The pair of sidewalls and the pair of endwalls integrally extend outwardly to form a first latching portion. A concave channel, a first concave region, and a second concave region are all formed in the base. The concave channel extends along a major axis of the base, while the first concave region extends from the concave channel to one of the pair of sidewalls, and the second concave region extends from the concave channel to the other of the pair of sidewalls. A lid is hingedly connected to the first latching portion. The lid includes a second latching portion corresponding to the first latching portion. The first and second latching portions lock together to retain the lid and the basket in a closed relationship.

  • Patent number: 6634517
    Abstract: A molded polymeric container includes a body portion having a sidewall and an integral champagne type base. The base includes a lower end that defines an annular contact ring for supporting the container with respect to an underlying surface. An annular step ring is defined immediately radially inwardly of the annular contact ring and has a radial length LS. The base further has a central push-up area and a generally concave transition region interposed between the central push-up area and the annular contact ring. The transition region further includes a plurality of integrally molded radially extending ribs, each of the ribs having a length LR. According to one advantageous aspect of the invention, the ratio LR/LS is within a range of about 1.0 to about 4.0.

  • Patent number: 6626324
    Abstract: A plastic container including a portion of a sidewall having an interior surface with an interior crystallinity, and an exterior surface with an exterior crystallinity. The interior crystallinity is greater than the exterior crystallinity. The higher crystallinity on the interior surface provides increased resistance to flavor scalping along the surface contacting the commodity, thereby minimizing flavor scalping of the commodities inside the plastic container.

  • Publication number: 20030121924
    Abstract: A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by a curved panel wall to an inner wall of an annular U-shaped countersink. The countersink has a generally cylindrical outer wall and an inner width less than the radius of the panel wall. The outer wall of the countersink connects with a frusto-conical chuckwall at a junction below the center panel, and the chuckwall extends to an inner wall of the crown at an angle of at least 16° with the center axis. In one embodiment, the chuckwall has an intermediate generally vertical short riser portion with small radii, the inner bottom width of the countersink is less than 0.040 inch, and the inner wall of the countersink extends at an angle less than 10°.

  • Publication number: 20030052133
    Abstract: According to one embodiment, a container comprises a basket and a lid. The basket has a base, a pair of sidewalls, and a pair of endwalls. The base, pair of sidewalls, and pair of endwalls are integrally connected. The pair of sidewalls and the pair of endwalls integrally extend outwardly to form a first latching portion. The base forms a concave channel, a first concave region, and a second concave region. The concave channel extends along a major axis of the base. The first concave region extends from the concave channel to one of the pair of sidewalls, and the second concave region extends from the concave channel to the other of the pair of sidewalls. At least one of the sidewalls and endwall intersections forms a wall ventilation aperture. The lid is connected to the first latching portion of the base. The lid has a second latching portion corresponding to the first latching portion of the base. The first and second latching portions are adapted to retain the lid and the basket in a closed relationship.

  • Patent number: 6527122
    Abstract: Stackable display bins for supporting quantities of cylindrical articles such as tubes of caulk and the like have U-shaped interiors that are accessible through U-shaped front openings. The bins have generally rectangular front, rear and side walls that connect with a symmetrically curved bottom wall to define their U-shaped interiors. The front, rear and side walls extend substantially vertically so they can directly underlie and overlie the front, rear and side walls of other identically configured bins in a vertically stacked array of bins. Removable extenders connect with the bins near front ends of the right and left side walls for pivotally mounting doors at locations spaced forwardly from the U-shaped openings for supporting signs that identify the contents of the bins. Methods of utilizing single bins and pairs of bins with short and long doors and removable interior partitions to display quantities of relatively large and relatively smaller sized tubes of caulk also are disclosed.
