A bag for the containment of fluent material, having an openable and reclosable pour spout. The bag includes a tubular bag body, and at least one flattened end forming a bag mouth. A closure flap emanates from one side of the bag mouth, to be folded over across the mouth to close the bag. A spout structure is affixed to an outer surface of one of the sides of the bag mouth. The spout structure includes a base sheet affixed to the bag body, and a spout flap releasably affixed to the base sheet. Upon sealing of the bag end, the spout flap becomes non-releasably affixed to an inside portion of the closure flap of the bag body. The spout flap is separable from the base sheet, via a first adhesive material is affixed to one or both of the spout flap and base sheet, for enabling repeated opening and reclosing of a portion of a portion of the bag mouth at the spout flap.

[ What is claimed is:] [1.]1. A bag apparatus, having a repeatedly openable and reclosable pour spout, comprising:a tubular bag body, fabricated from at least one layer of bag material;the tubular bag body having at least one end configured to form an open mouth and having first and second opposing sides adjacent the mouth;the first and second sides of the tubular bag body defining long and short steps, respectively;a closure flap emanating from the first of the opposing sides of the mouth, and operably configured to be folded along a fold line across the mouth and over at least a portion of an outer surface of the second of the opposing sides of the mouth, and wherein the substantial majority of the width of the short step of the tubular bag body is folded over upon itself;the closure flap having an inside surface operably configured to be placed in juxtaposed alignment over the at least first portion of the outer surface of the second of the opposing sides of the mouth;a spout structure, operably affixed to a portion of the outside surface of the tubular bag body, includinga base sheet, operably positioned on and over at least a further portion of the portion of the outer surface of the second of the opposing sides of the mouth, the base sheet having an outside surface;a spout flap, operably disposed in substantially aligned overlying contact with the base sheet;a first adhesive material operably arranged on at least one of the inside surface of the spout flap and the outside surface of the base sheet and configured to releasably hold the spout flap to the base sheet, after the spout flap and the base sheet have been brought into the substantially aligned overlying contact with each other;the spout structure being operably disposed on the further portion of the portion of the outer surface of the second of the opposing sides of the mouth, so that upon operable positioning of a second, substantially non-releasable adhesive material upon the inside surface of the closure flap and further upon the juxtaposed alignment of the closure flap over and against the portion of the outer surface of the second of the opposing sides of the mouth, the spout flap becomes non-releasably affixed to a portion of the inside surface of the closure flap;the short step being provided with a downwardly cut portion, below which the spout structure is positioned, to enable the spout structure to be positioned in close proximity to the fold line, towards preventing contact between the short step and the outer surface of the spout structure, when the closure flap is folded over the fold line;complete separation of the spout flap from the base sheet enabling a portion of the mouth of the bag to be reopened for providing access to an interior region of the tubular bag body, the first adhesive material permitting the spout flap and base sheet to be repeatedly separated and releasably reattached to one another, to, in turn, permit at least a portion of the mouth to be repeatedly opened and reclosed,whereupon opening of the bag, the first adhesive remains on at least one of the spout flap and the base sheet.
