    • 专利摘要:
    A reclosable cross-bottom sack is provided over the cross-bottom with a cover sheet having an incision and lines of weakness. A flattened tubular plastics emptying nipple for the sack is folded and cut at one end to define flaps, extends through the incision and is secured to the sheet by its flaps to lie between the cross-bottom and the cover sheet.

    (5) MULTIPLE USE BAG
    one
    The invention relates to the food industry, in particular to a bag for repeated use, used in the packaging of various products.
    A reusable bag is known, comprising walls and a cruciform bottom with a slit for accommodating a sleeve therein for discharging the contents of the bag tl.
    However, the known bag has a complex structure and requires an increased consumption of material in the manufacture.
    The purpose of the invention is to simplify the design of the bag and save material for its manufacture.
    This goal is achieved by having a reusable bag containing walls and a cross-shaped bottom with a slit for placing a sleeve for discharging the contents of the bag, the sleeve has side folds; the inner surface of the bottom, and the edges of the lower end of the sleeve are connected by a transverse weld seam.
    At the same time, the cruciform bottom crack is bounded on both sides by parallel lines of weakened strength.
    Yu In FIG. 1 schematically depicts a reusable bag, partly in a perspective view; in fig. 2 slit, cruciform bottom with lines of weakened strength; in fig. 3
    15 sleeve with side folds and undercuts -, - on FIG. - bottom of the bag with the sleeve. The bag contains walls 1 and a cross-shaped bottom 2 with a slit 3 for placing a sleeve for release therein.

    20 bag contents. The sleeve k has side folds 5. In the upper part of the sleeve k, cuts are made to form rectangular elements 6, by means of which the sleeve k is welded to the inner surface of the bottom 2. The edge of the lower end of the sleeve is connected by a transverse weld 8. The slot 3 is cross-shaped bottom 2 bounded on both sides by parallel lines 9 of weakened strength. In the process of manufacturing, sleeve k with side folds 5 is connected with a cross-shaped bottom 2, for which end of sleeve C with side folds 5 is allowed through slot 3 of cross-shaped bottom 2 until the part 10 of sleeve k with side folds 5 is laid flat on the inner side of the cruciform bottom 2. Then the rectangular elements 6 are connected by means of welds 7 to the cross-shaped bottom 2. The wedge elements (not shown) formed by cuts can also be welded to the cross-shaped bottom 2 by displacing the welds inwards so that they also simultaneously cover the side edges of the adjacent rectangular elements 6 by means of welds 11. To lower or partially empty the bag, the lower end of the sleeve + with the side folds 5 above the transverse weld 8 is cut through; parallel lines 9 of weakened strength and an incision is made in the slit 3 to form an opening through which the product in the bag is discharged. The bag emptying process can be interrupted by squeezing the lower end of the sleeve 4 with side folds 5 The proposed bag is simple in its construction, economical in manufacturing due to low material consumption and ensures complete or partial selection of the product from it through the slot of the cross bottom and placed in it sleeve. Claims of the invention A reusable bag containing walls and a cross-shaped bottom with a slit for placing a sleeve in it for discharging the contents of the bag, in order to simplify the bag design and save material for its manufacture, the sleeve has side folds, the upper part of it is cut to form rectangular elements by means of which the sleeve is attached to the inner surface of the bottom, and the edges of the lower end of the sleeve are connected by a transverse weld stitch.
