Abstract

937,264. Bags. RODEFFER INDUSTRIES Inc. Feb. 6, 1961, No. 4420/61. Class 94(2). [Also in Groups V and XXX] A container for use in the preparation of concrete (see Group V) comprises a bag of substantially ovoid configuration made of a flexible material. The bag, 10, Fig. 1, is made up of fabric panels 24 which are tied together by lacing 36 and whose edges are bound with a nylon tape material. The panels may be made of a tightly woven nylon fabric which is impregnated with a vinyl plastic material to reinforce and waterproof the fabric. The interior of the bag is divided into two compartments 14 and 16, as shown in the cross-sectional view represented by Fig. 3, by two further panels 24a, and compartment 16 is provided with a waterproof lining 18 made up of panels 28. Compartments 14 and 16 are used for storing cement and moist aggregate material respectively. A fabric collar 38 is stitched to the upper edges of the panels 24 to define a container mouth which itself has two smaller mouths 40 and 42, one for each compartment. The mouth of the container can be closed in a moistureproof fashion when the bag is loaded, and a ring 22 at the bottom of the bag enables it to be suspended upside down for gravitational discharge of its contents. The precise details of the construction and functioning of the bag are amply illustrated in other Figures which are not shown here.
