    A plastics sack made from tubular material has one end of the tube folded to form a base defined by two triangular tucks interconnected by a welded-on or heat sealed joining strip, and two side flaps which incorporate the ends of the joining strip. A cover sheet is adhered over part of the corner tucks and over only one of the side flaps. The other side flap can be pulled out from beneath the cover sheet to form a controlled outlet for the sack contents or is temporarily secured to the outside of the cover sheet so that it can be readily detached for the same purpose.

    (5) PLASTIC BAG (ITS OPTIONS)
    This invention relates to the field of packaging. A plastic bag is known that contains walls and a rectangular bottom, two plates are placed along its diagonal, external and internal fl} In a known bag, the contents can be extracted only if the entire bottom is destroyed. The aim of the invention is to increase the convenience of operation. This goal is achieved by the fact that in a plastic bag according to the first variant, containing walls and a rectangular bottom, on the diagonal of which two plates are placed, external and internal, the internal plate is attached to the walls along the entire perimeter, and protruding bottom corners the plate is bent so that one of them is placed between the inner and outer plate, and the other is placed on the outer surface of the outer plate and its end section is attached to the last one. This goal is achieved by the fact that in a plastic bag according to a second variant, containing walls and a rectangular bottom, on the diagonal of which two plates are placed, are external and internal, the internal plate is attached to the walls around the perimeter, and the projecting corners of the bottom with the internal plate placed on them are bent so that each of them is placed between the inner and outer plates, and only one of these angles is attached to the latter. FIG. 1 shows a plastic bag with an overlaid inner plate, top view; in fig. 2 - the same, with a welded inner plate; in fig. 3 bag when folded, the first option; in fig. 4 and 5 - a bag in folded form, the second option (two types). 39 A bag is a tubular piece of a single or multi-layer strap (or laminated plastic tape fabric-), which is elongated to form a rectangular bottom, having an inner face 1 and an outer 2 superimposed at the interface around the perimeter. 2. Plate 1 It can also be connected to the bottom by welding, namely welds 3, L and 5 and 6. In FIG. 3 shows a variant of making the bag when the protruding angles 7 and 8 of the bottom with the inner plate 1 placed on them are bent along the bend line 9 so that one of them is placed between the inner and outer plate 2 and the other is placed on the outer surface of the outer The plate 2 and its end portion are attached to the latter with, for example, glue swab 10 and glue strips 11. For opening the bottom, the end portion together with the weld seam 6 is cut off along the dash-dotted line 13 so that an emptying hole is obtained. From this opening, the bag suspended by the hook can be emptied easily and in a metered quantity into the funnel. FIG. an embodiment of the bag is depicted when the protruding 7-bottom corners with the inner plate 1 placed on them are bent along the bend line 12 so that each of them is placed between the inner 1 and outer 2 plates, with only one of the corners attached to the latter. To prevent gluing outside the plate 2 with the protruding angle 8, the said plate is provided with an adhesive coating only above the 1C dash-dotted line. The protruding angle 7 not glued from the plates can be pulled out of the pocket formed between the plate 2 and the bottom of the bag and then opened in the same way as described for the first variant. . .In FIG. 5 shows the same embodiment as in FIG. k, but folded along the inflection line 15, the protruding hugo 8 is bent backwards along the inflection line 1 7.4 (shown as a dashed line) onto itself in such a way that the end portion of the angle 8 provided with the weld seam supports the outer plate 2. The latter, in turn , above the dash-dotted line 17, is provided with an adhesive layer that does not stick together with a bent angle 13 and laid on itself angle 8. The emptying of the bag is carried out as in the variant shown in FIG. 4. The proposed bag design allows emptying from the bottom without causing damage to the bag itself. The bag is easy to use and easy to manufacture. Invention 1. A plastic bag containing walls and a rectangular bottom, on the diagonal of which two plates are placed externally and internally, so that, in order to increase the convenience of operation, the inner plate is attached to the walls throughout perimeter, and the protruding corners of the bottom with the inner plate placed on them are bent so that one of them is placed between the inner and outer plate, and the other is placed on the outer surface of the outer plate and its end section is attached to the latter. , 2. A plastic bag containing walls and a rectangular bottom, on the diagonal of which two plates are placed, external and internal, characterized in that, in order to increase the convenience of operation, the internal plate is attached to the walls around the perimeter, and protruding bottom corners with they are bent on the inner plate so that each of them is placed between the inner and outer plates, and only one of the corners is attached to the latter.
