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.

A pouring attachment for use on a container having an annular rim defining an open top of the container, said attachment comprising: (a) a resiliently semi-rigid, semi-flexible, annular split retainer removably mountable about an interior of the annular rim of the container, said annular split retainer having a pouring side and an opposite non-pouring side; and (b) a pouring structure having a non-continuous arcuate shape extending less than 360°an being removably mountable to said annular split retainer so as to extend substantially perpendicular to a plane defined by said annular split retainer and encompass only said pouring side of said annular split retainer, said non-pouring side of said annular split retainer having a pair of spaced apart adjacent end portions defining a gap therebetween which is located substantially opposite said pouring structure, said annular split retainer being capable of flexing circumferentially between contracted and expanded configurations which, in turn, cause said end portions thereof to move toward and away from one another and permit installation and removal of said retainer to and from the container rim; (c) said pouring structure having a lower edge portion being prefolded to define an upwardly-opened annular pocket adapted to receive and wrap partially about said annular split retainer so as to surround and completely cover surface portions of said retainer which otherwise would be contacted by a fluid as it is poured from the container over said pouring attachment; (d) said preformed lower edge portion of said pouring structure and said outer circumferential surface of said annular split retainer having respective cross-sectional profiles substantially identically configured to conform in shape and mate with one another and with an inner circumferential surface on the interior of the container rim.
