ABSTRACT:
A pouring attachment for use on a container having an annular rim defining an open top of the container includes a resilient, semi-rigid semi-flexible, annular split retainer for mounting about the interior of the container rim and at least one, and preferably, a plurality of different pouring structures, such as of spout, funnel and filter configurations, removably mountable at separate times to the annular split retainer. The different pouring structures are interchangeable with one another for adapting the pouring attachment to accommodate different types of pouring requirements. Each pouring structure is mountable at a prefolded lower edge portion thereof to the annular split retainer so as to surround and completely cover surface portions of the retainer at the pouring side thereof which surface portions would otherwise be contacted by a fluid as it is poured from the container over the pouring attachment. The retainer has a pair of spaced apart adjacent end portions defining the split or gap which is located substantially opposite the pouring structure. The split or gap allows flexing at the opposite side portions of the retainer between contracted and expanded configurations which, in turn, causes the end portions of the retainer to move toward and away from one another and permit installation and removal of the retainer to and from the container rim. Arcuate-shaped upturned finger holds are defined at the end portions of the retainer for facilitating gripping and flexing of the annular retainer.
