Flexible container and reusable closure element

1. An assembly for providing a choice of closing systems, said assembly comprising:

(a) at least one flexible container which comprises:

(i) a pouch formed from a flexible sheet material, said pouch having one or more walls formed of the sheet material including a top wall, that define and enclose an interior space;

(ii) a dispensing opening in the sheet material through the top wall, through which the interior space is accessible, said dispensing opening being delimited by a border;

(iii) a sealing area of the sheet material substantially surrounding said dispensing opening, the sealing area being defined by an area on which a non-permanent adhesive material is disposed on the sheet material;

(iv) a releasable flexible sealing member adhered to the sealing area by the non-permanent adhesive material, the releasable flexible sealing member covering the entirety of the sealing area;

(v) a plurality of separable sheets present in said interior space; and

(b) a closure element comprising:

(i) a base having a top surface and a bottom surface, an outer rim and an inner rim, the bottom surface having a bottom surface area and being of a size and shape configured to contact the sealing area about the dispensing opening, wherein when the closure element is appropriately superimposed to the sealing area, a contact area between the sealing area and the bottom surface comprises at least 20% of the bottom surface area;

(ii) a dispensing aperture defined by the inner rim of the base; and

(iii) a lid for sealing the dispensing aperture;

wherein the non-permanent adhesive material is operable to effect releasable and repeatable adherence of the releasable flexible sealing member directly to the sealing area, and the non-permanent adhesive material is operable to effect releasable adherence of the bottom surface of the base directly to the sealing area; and

wherein said sealing area is delimited by an outer perimeter line and an inner perimeter line, wherein said inner perimeter line is spaced from the border of said dispensing opening by a distance d of between 0.1 and 20 mm.
