Tamper evident pull-out spout

摘要

A tamper evident, pull-out flexible spout for use in combination with a container lid wherein a cap can only be removed from the threaded end of the spout by lifting a pair of bail rings which are attached to the cap by way of a set of frangible connectors and thereafter pulling the spout out from the stored position at least part way toward the use position thereby to disengage lugs on an exterior surface of the cap from a pair of one-way stops on an interior surface of the spout ring.

主权项

1. A tamper evident, pull-out spout for a container having a lid comprising:
a flanged annular body adapted to be attached to an opening in a lid; a flexible spout integral with the body and being foldable concentrically into the body to provide a storage position but extendable outwardly from the body for use; a cap threadably engagable with the spout for closing same and rotatable in opposite on and off directions; at least one bail integrally attached to the cap in surrounding relation and being further attached to the cap by at least one frangible section which must be broken to raise the bail to a use position; and means for preventing rotation of the cap relative to the spout in the off direction whenever the spout is in the stored position, said means comprising at least one one-way stop formed on an interior surface of the annular body and at least one lug formed on an outside surface of the cap and dimensioned to cooperate with the one-way stop on the body to permit rotation in the on direction but to prevent rotation in the off direction whenever the spout is in the stored position but permit rotation of the cap in both directions whenever the spout is extended at least partly to the use position.
