<p>A tap for use in association with bag in box containers comprising a body, a plug member, an upper seal assembly and a lower seal assembly. The body includes a tap nozzle in the form of an elongated tube having an inner surface and an outer surface, a handle opening at a first end and a dispensing opening at the second end. A nozzle opening extends into the elongated tube between the first and second ends and is placeable in fluid communication with a bag of a bag in box container. The plug member is structurally configured to fit and slidably move within the elongated tube of the body such that the outer surface of the plug member faces the inner surface of the elongated tube. In the open orientation, the nozzle opening is in fluid communication with the dispensing opening. In the closed orientation, the nozzle opening is precluded from fluid communication with the dispensing opening. The upper seal assembly includes an upper seal surface region and an upper seal bead positioned between the nozzle opening and the handle opening of the body. The upper seal assembly maintains continuous sealing engagement between the closed orientation and the open orientation of the tap.</p> |
