  • Patent number: 6499721
    Abstract: There is disclosed herein a bulk container valve for use with a bulk container having a tubular spout. The valve comprises a one piece plastic housing having an interior chamber connecting a front port to a rear port. The housing includes a rear fitting about the rear port for connection to the spout, in use, and a front fitting about the front port. A one piece plastic cylindrical valve element is rotationally supported in the interior chamber of the housing for movement between a valve open position and a valve closed position. The valve element includes a handle for selective rotation of the valve element. A collar secures the valve element to the housing to maintain the valve in assembled condition.

  • Publication number: 20020109116
    Abstract: A bulk container valve is adapted for use with a bulk container having a tubular spout. A plastic housing has an interior chamber connecting a front port to a rear port. The housing is connected to a rear fitting about the rear port for connection to the spout, in use. The rear fitting comprises a cylindrical neck having an annular flange. A valve element is rotationally supported in the interior chamber for movement between a valve open position and a valve closed position. A handle is operatively mated with the valve element for selective rotation of the valve element. A one-piece, all plastic collar is received on the rear fitting. The collar comprises a tubular body including an inner threaded wall for threading on the spout and an end wall having a through opening. The through opening is larger than the neck and smaller then the flange whereby the end wall is captured between the plastic housing and the flange.

  • Patent number: 6161715
    Abstract: A pallet bin comprises a generally rectangular base having a generally planar support surface. A pair of opposite side panels and a pair of opposite end panels between the side panels each stand vertically at one side of the rectangular base to define a parallelepiped interior space. Each of the side panels and end panels comprises a planar outer wall and a planar inner wall and an internal rib structure connecting the outer wall spaced from the inner wall to define hollow portions therebetween. A tubular column is supported on the base within the interior space.

  • Patent number: 5458069
    Abstract: A plastic skid has longitudinally extending plastic rails and plastic cross members which extend transversely between the rails. The rails are injection molded and have an upper flange engageable with cargo to be supported on the skid and a lower flange engageable with a support surface. Each rail has a width characterized by the width of the upper flange and the lower flange. An integral longitudinal web extends between the upper flange and the lower flange of a rail. The web has a width which is substantially less than the width of the rail. An integral rib is provided on the web for enhancing the stiffness of the rail. The cross members are injection molded and have a tapered opening. A series of posts are integral with the rails and each engage a corresponding one of the cross member openings. The posts are ultrasonically welded to the cross members within the openings.
