Abstract: A disposable valve mounted to the wall and extending within the interior of containers such as disposable air bags or bulk containers includes a valve body having a hollow interior which receives a valve plug formed with a closure plate at one end and at least one fluid flow passageway. The valve plug is moved relative to the valve body by a fluid injector tip to an open position in which a portion of one or more fluid flow passageways in the valve plug extends exteriorly of the valve body and within the interior of the container to permit the passage of fluid therethrough, and then either in or out of the container.

Abstract: A skid top for protecting a skid load of material includes a paperboard sheet having a planar dimension generally corresponding to the length and width of the skid load upon which it is to be used and a peripheral frame laminated thereto formed of laminated paperboard members folded upon themselves and laminated to themselves. In a presently preferred form, the paperboard sheet includes side flaps adapted to be bent down over the top edge of the skid load and paperboard slats laminated to the side flaps. The invention is characterized in part by its improved design, light weight, ease of handling, economies of manufacture, and the improved protection it provides to skid loads.
