Abstract
A bag construction for use to distribute flowable material is provided. The bag construction generally includes first and second panels or panel sections oriented juxtaposed to one another. In one end of the bag construction, a base gusset is provided between the panels. The base gusset includes apertures therein, for distribution of flowable materials. In preferred embodiments, a rib-and-trough closure arrangement is provided so that the pouch construction can be selectively closed to inhibit distribution of material, when desired. Methods of preparing such arrangements and methods of use are provided.
Claims20
A bag construction 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 secured to one another along at least a portion of said panel section side edge portions, to define a bag construction interior and opposite side edges;
- (b) a base gusset member;
- (i) said base gusset member being oriented in extension between said first and second panel sections, across an end of said bag construction interior;
- (ii) said base gusset member including distribution apertures therein;
- (c) a first transverse seal oriented to seal said first and second panel sections to one another;
- said first transverse seal being positioned to extend transversely across said bag construction at a location between said base gusset member and said first end edges of said first and second panel sections;
- (d) a first transverse openable and reclosable closure arrangement extending between said first and second panel sections;
- said first transverse openable and reclosable closure arrangement being positioned to selectively seal said first panel section to said second panel section along a closure line oriented between said base gusset member and said second end edges of said first and second panel sections;
- and
- (e) a transverse openable and reclosable top closure arrangement extending between said first and second panel sections;
- said top closure arrangement being positioned to selectively seal said first panel section to said second panel section along a closure line oriented between said base Gusset member and first end edges of said first and second panel sections.
