Abstract
A vented pouch arrangement is described which comprises: first and second opposed panel sections; a base gusset member; and, a gas filter arrangement oriented in one of the panel sections. The gusset member is preferably oriented between the panel sections; along ends thereof, to form a base by which the arrangement can be stood up during use. Preferably, the arrangement is provided with a rib and trough closure arrangement extending thereacross. In this manner, opening and reclosing the bag construction, for access to material therein, is facilitated. A method for formation of such a pouch arrangement, and methods of use, are also described.
Claims7
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 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 interior and side seals;
- (b) a base gusset member;
- (i) said base gusset member being oriented in extension between said first and second panel sections, along said second end edges thereof, to close an end of said pouch construction interior;
- (ii) said base gusset member being constructed and arranged to support said pouch arrangement in a standing orientation, upon said base gusset member, at least when said pouch arrangement is partially filled with material;
- (c) a gas filter arrangement oriented in one of said panel sections;
- said gas filter arrangement being constructed and arranged for gas flow outwardly therethrough, in response to a greater than ambient gas pressure within said pouch arrangement when closed;
- said gas filter arrangement comprising a pore in said first panel section having a porous member mounted thereover;
- and,
- (d) closure means comprising a rib and trough closure arrangement extending between said opposite side edge portions of said panel sections;
- (i) said gas filter arrangement pore being positioned a first distance from said rib and trough closure arrangement and toward said panel section second end edges;
- said first distance being about 2% to about 30% of a distance between said rib and trough closure arrangement and said panel section second end edges, and in a portion of first panel section slanted toward said second panel section, when said pouch arrangement is partially filled and oriented in the standing orientation;
- and,
- (ii) said gas filter arrangement being oriented for communication with said pouch construction interior, when same is closed by said closure means.
