Abstract
Abstract There is described a container for dispensing liquids in which an elongated, resilient, delivery tube is positioned within the container in a deflected and compressed condition, so that when a closure is removed from an opening in the container the upper end part of the delivery tube is urged out of the container by its own resilience. The delivery tube is then grasped and pulled outwardly until cooperating formations on the lower end of the delivery tube and the container nozzle form a seal therebetween. A flexible wall or diaphragm may be provided to expel fluid from the container. After use, the delivery tube is replaced within the container by pushing the first end part, and a cap is placed over the opening in the container.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
176 words
In a dispensing container for liquids, having a reservoir and a one-piece exit nozzle which is an outwardly extending tube with an outwardly diminishing tapered bore, and provided with a closure at the outer end, the improvement comprising a resilient delivery tube in a resiliently bent position within the reservoir, a first end of said delivery tube abutting an internal surface of the reservoir and a second end of said delivery tube extending into the tapered bore of the exit nozzle and abutting the closure thereof, the length of said delivery tube being greater than the distance between the points of abutment so that said tube is held in a flexed condition whereby upon removal of the closure from the nozzle the resiliency of said delivery tube forces said second end to protrude outwardly from the nozzle; and an enlarged portion defined on said delivery tube adjacent said first end whereby when said delivery tube is pulled outwardly from the reservoir, said enlarged portion engages the internal surface of the tapered bore forming a seal therebetween.
Claim 2
Dependent Claim
