Abstract
A quick-removable closure attachment for the depending spout of a flexible hopper bag. The spout has a rigid horizontal conduit secured to its intermediate portion. To close the spout it is folded around the conduit. A holding clip has a bottom rod and a pair of gripping bars spaced upwardly from the rod, parallel thereto and located on opposite sides thereof at different heights. The bottom rod is inserted through the conduit and the folded spout is received grippingly between the gripping bars, holding the spout closed. To allow discharge from the hopper bag, the clip is withdrawn, allowing the spout to unfold and drop to its open depending position.
Claims9
A flexible hopper bag having a dependent spout, and a guide conduit horizontally secured on an intermediate portion of the spout, in combination with a closure clip for the bag spout, said clip comprising a rigid main body member, a guide rod rigidly secured to said body member, and a pair of gripping bar elements rigidly secured to said body member and extending substantially parallel to said guide rod, spaced upwardly therefrom and located on opposite sides thereof, said guide conduit slidably receiving said guide rod and the folded flattened spout being grippingly received between said gripping bar elements when the spout is flattened and folded around said guide conduit and the guide rod is inserted in the conduit, whereby the spout may be at times released to drop to a depending open condition when the clip is disengaged therefrom.
A quickly attachable and detachable closure clip for a flexible hopper bag spout such as used for loading agricultural aircraft, or the like, comprising a rigid thin plate member, an elongated guide rod considerably longer than any dimension of said plate member and of sufficient length to completely span the width of and be received in the fold of a bag spout when such spout is flattened and folded upwardly, said guide rod being rigidly secured to said plate member to extend substantially perpendicular thereto from one side surface thereof, a pair of similarly elongated gripping bar elements rigidly secured to the same side of said plate member and extending substantially parallel to said guide rod, spaced upwardly therefrom and located on opposite sides thereof, and a handle member projecting outwardly from the opposite side of said plate member, whereby a folded flexible hopper bag spout may be grippingly received between said gripping bar elements to close the bag spout and the bag spout may be quickly released to a depending opening condition when the clip is disengaged therefrom.
