    • 专利摘要:
    A sack made from a tube of plastics material has its bottom constructed by folding an end portion of the tube so as to form two coplanar substantially isosceles triangular flattened portions with spaced confronting bases defined by plain edges and sides defined by fold lines. The space between the bases is bridged by a strip of material that overlaps the bases of the triangles and also projects beyond the base angles of the triangles. The projecting ends of the strip are folded over and the strip is welded to the sack bottom by seams which intersect at the fold lines.

    专利说明:

    The invention relates to a container for a bulk material, in particular to bags made of a fabric, the outer side of which is covered with art by the HNM material, and can be widely used in various areas of the national economy.
    Known bag, made from a length of sleeve, formed in the bottom of the wall which form the bottom sheet tl.
    A disadvantage of the known bag is the complexity of its manufacture.
    A bag is made of a length of sleeve made of fabric, the outer side of which is covered with artificial material or is laminated with a foil made of artificial material, and which can have a square bottom formed by parts of the sleeve with a gap between them and a rectangular plate 2 rigidly fixed on them.
    A disadvantage of the known bag is that the inner bottom portion is not connected to the outer sides of the bag walls, as a result of which the strength and the sealing of the bag are insufficient.
    The purpose of the invention is to increase the bag sealing.
    To achieve this goal, in a bag made of a piece of a sleeve made of fabric, the outer side of which is covered with artificial material and laminated with a foil of artificial material and having a square bottom formed by parts of the sleeve with a gap between them and a rigidly fixed rectangular one. plate, the dimensions of the plate exceed the size of the gap, forming the edges, which are imposed on the outer side of the sleeve and rigidly connected to it by welding.
    The drawing shows a bag, a general view.
    The bag is made of a piece of sleeve jl. In this case, a fabric is used, the outer side of which is covered with artificial material or is lined with foil of artificial material. The bag has a square bottom, formed by parts of the sleeves with a gap between them. On these parts the sleeves are rigidly fixed to the rectangular plate. Strip 2. The dimensions of the plate exceed the dimensions of the gap, forming the edges 3,
    which are superimposed on the outer side of the sleeve 1 and rigidly connected with it
    by welding
    The invention provides a solid construction used under the bulk material and provides reliable
    . sealing the proposed bag.
