1. A pouch arrangement comprising:

  • (a) first and second, opposed, panel sections;

    (i) each of said panel sections having a first end edge, a second end edge and opposite side edge portions extending between said first and second end edges;

    (ii) said first and second panel sections being sealingly secured to one another along at least a portion of said panel section side edge portions, to form a pouch construction having an exterior surface, an interior and side seals;

    (iii) said first and second panel sections being secured together along each of said panel section first end edges to form an end seal and to close a first end of said pouch construction;

    (A) said end seal being selectively removable from a remaining portion of said pouch construction, when access to said pouch construction interior is desired;

    (b) a base gusset member;

    (i) said base gusset member between said first and second panel sections, along said second end edges thereof, to close a second end of said pouch construction;

    (ii) said base gusset member being constructed and arranged to support said pouch construction in a standing orientation, on said base gusset member and with said first and second panel sections extending upwardly therefrom;

    (c) a rib and trough closure arrangement extending between said opposite side edge portions of said panel sections and being oriented between said end seal and said base gusset member;

    (i) said rib and trough closure arrangement being constructed and arranged for selective closure of said pouch construction at said first end, when said end seal has been removed;

    (d) said pouch construction interior being at least partially filled with coffee beans;

    (i) said coffee beans filling said pouch construction interior between said base gusset member and a level below said rib and trough closure arrangement when said pouch construction is in a standing orientation;

    (ii) said coffee beans releasing gases within said pouch construction interior; and

    (e) a gas vent arrangement oriented on said first panel section;

    said gas vent arrangement being;

    constructed and arranged for selective flow of gas outwardly therethrough from said pouch construction, in response to a selected greater than ambient gas pressure within said pouch construction when closed; and

    constructed and arranged to inhibit gas flow into said pouch construction when said pouch construction is closed and a gas pressure within said pouch construction does not exceed said selected greater than ambient gas pressure;

    (i) said gas vent arrangement comprising at least one pore in said first panel section and covered by a control member;

    (A) said gas vent arrangement being oriented on said first panel section between said rib and trough closure arrangement and said base gusset member to permit said control member to selectively control passage of gas being released from said coffee beans through said at least one pore.
