Abstract
The present invention 10 discloses stackable bag containers 12 having opposing mating rigid planar elements 14, 15 disposed on the interior of the bags contiguous to the walls of the bag 12 having impressed therein interlocking curvilinear grooves 16, 17 extending across the rigid element 14, 15 and terminating spaced away from the periphery edge 20 of the rigid planar element 14, 15. Bag locking device 26 are provided. Embodiments utilizing corrugated walls 30, circular indentions 32 and cross line indentions are also disclosed along with an embodiment providing a sanitary storage bag for use with a conventional flowable product dispenser.
Claims15
In a plastic bag having a first and a second wall and a bag lock, the improvement comprising:
- a) a first rigid planar member disposed on a first wall internal of the bag, said first rigid planar member being complementarily shaped as the bag, said rigid member being smaller than the bag for the bag to receive said rigid member therein;
- b) a second rigid planar member disposed on a second wall internal of the bag, said second rigid planar member being complementarily shaped as the bag, said rigid member being smaller than the bag for the bag to receive said rigid member therein;
- c) a plurality of first convex grooves disposed in said second rigid planar member, said grooves being parallel to each other;
- and,
- d) a plurality of second concave grooves disposed in said first rigid planar member, said grooves being parallel to each other, said concave grooves for receiving said convex grooves of said second rigid planar member when a first bag is stacked on a second bag.
In a flowable product dispenser having an outlet for the flowable product and an inlet for the flowable product, the improvement comprising:
- a) a plastic bag having a first and a second wall;
- b) a first rigid planar member disposed on said first wall internal of the bag, said first rigid planar member being complementarily shaped as the bag, said rigid member being smaller than the bag for the bag to receive said rigid member therein;
- c) a second rigid planar member disposed on said second wall internal of the bag, said second rigid planar member being complementarily shaped as the bag, said rigid member being smaller than the bag for the bag to receive said rigid member therein;
- d) a plurality of first convex grooves disposed in said second rigid planar member, said grooves being parallel to each other;
- e) a plurality of second concave grooves disposed in said first rigid planar member, said grooves being parallel to each other, said concave grooves for receiving said convex grooves of said second rigid planar member when a first bag is stacked on a second bag;
- f) a welded seam lock disposed on said bag to enclose said bag;
- and,
- g) a means for an outlet disposed on said bag whereby the contents of the bag can be transferred to the inlet of the flowable product dispenser.
