    A reclosable sack having a cross-bottom formed by folded-over side flaps has the confronting edges of the flaps spaced apart to define a slideway for a closure strip which is provided with a hole and is retained in the slideway by a cover sheet. When the closure strip is slid to a position where the hole is out of registry with emptying holes pierced in the material overlying and underlying the strip, the sack is substantially sealed.

    (54) BAG
    The invention relates to packaging, in particular to the design of soft packaging.
    Bags made of tubular material are known, having a closure s and a bottom consisting of two parts one above the other, of which the valves 113 and C 2 have the upper parts.
    However, upon partial unpacking of known sacks, the problem of their closing arises.
    The purpose of the invention is usability.
    The goal is achieved by the fact that in a bag made of a sleeve, ts having a closure and a bottom consisting of two parts located one above the other, the upper part of which has valves and a closure, the latter is a strip of flexible material with an opening m and is located between the parts of the bottom with the ability to move. neither
    FIG. 1 shows a bag, top view; in fig. 2 - bag shutter.
    Bag 1 has a Bottom, made of two located One above the other, second parts.
    The upper part has valves 2 and 3 and the lower part is formed by a sheet C, the shutter 5, made of flexible material and having an opening 6, is located between the valves 7 and 8 and the sheet C with the possibility of movement.
    At the moment when the bags are in the filled and empty state, the opening 6 of the shutter 5 is displaced relative to the middle of the bag. When it is necessary to empty the bag, the shutter is moved so that its opening 6 is aligned with the middle of the sheet C and pierced last, while the material in the bag can be poured out. If not the whole bag is to be emptied at one time, but only part of the material is taken, the shutter is moved so as to displace the opening 6 relative to the opening formed in the sheet 4.
    The proposed bag improves usability by creating an option.
    use of the necessary part of the material.
