Definitions

  • the present invention relates to a tight, flexible container, of large capacity for the packaging of pulverulent products or of very small particle size.
  • the outer casing which constitutes the resistant part of the packaging is a polypropylene fabric while the inner casing is a polyethylene sheath which provides sealing.
  • the body of the inner sheath called sache is usually glued to the outer shell and its bottom is welded. Its upper part or mouth is ligated after filling in order to avoid any entry of water in contact with the product.
  • FR-A-2450754 describes a large-capacity waterproof bag provided with an internal bag secured to the external envelope.
  • This outer casing has a side slit and two opposite lifting eyes.
  • US-A-2789728 describes and illustrates a packaging for fluent materials. Part of this packaging is transformed into a chute by detaching it from the main body along the line of weakness. This chute is a chute for emptying the contents of the packaging.
  • US-A-3473703 describes a packaging for fluent materials.
  • a passage 22 is provided in this packaging which is transformed into a chute by detaching it from the main body along the welding lines 20.
  • This chute is a chute for emptying the contents of the packaging.
  • a disadvantage of the large capacity waterproof containers according to the prior art of the type described above is that very often a rupture of the bag due to the way it is put in place.
  • the object of the present invention is to remedy the problem mentioned above by providing greater security in terms of sealing and by facilitating use for filling the container and closing it after filling.
  • a sealed container (1) for the packaging of powdered products or of very small particle size, comprising an external envelope consisting of two canvas panels (2) assembled by seams (3, 4, 5, 6 ) both laterally and transversely and an internal envelope (8) bonded to the two canvas panels and the bottom of which is welded, said external envelope having near the upper part at least one longitudinal slot, lateral opening 7, through which a mouth (tubular part 10) of the internal envelope can come out, the bottom of said external envelope sewn by one of the transverse seams (3, 4) being brought together to form a lower bun (15) which is ligated by a link (16) while its mouth is assembled and ligated by one or more links or by a canvas strip (17) to suspend it from a hook (23), the longitudinal slit is produced by an interruption of one (5) of the seams lateral res (5, 6) to provide a lateral opening (7), the mouth of the internal envelope (8) is produced in the form of a tubular part (10) by making a longitudinal
  • the container according to the present invention is generally designated by 1.
  • the container 1 comprises an external envelope made up of two canvas panels 2.
  • the canvas panels 2 are advantageously polypropylene. They are assembled at the bottom, by a transverse seam 3 and at the mouth by another transverse seam 4.
  • the canvas panels 2 are also assembled by two side seams 5 and 6.
  • One of the side seams, the seam 5 in the example shown in FIG. 1 is interrupted near the upper part lower or mouth to provide a lateral opening 7.
  • Both the side seams 5, 6 and the transverse seams 3, 4 can be produced with a polypropylene thread.
  • an internal gianne or bag 8 of the same width is inserted therein and does not have bellows.
  • Bag 8 is usually made of polyethylene. This bag 8 is glued to the two canvas panels 2 by cords of hot-melt adhesive 9, so as to obtain a good deployment at the time of pre-inflation and a correct positioning relative to the external envelope. This avoids any risk of rupture of the bag 8 at the time of filling and therefore perfect security is obtained as regards sealing.
  • the bottom of the bag 8 has been welded.
  • the bag 8 has at its upper part a tubular part 10 which is obtained by making a longitudinal slot 11.
  • a transverse weld 12 as well as a longitudinal weld 13 ensure the formation of the tubular part 10 of the bag 8.
  • the bottom of the know 8, below the weld has a flap 14 which is taken in the seam 3 of the bottom of the container 1.
  • the bottom of the container 1 which has been sewn as indicated above is gathered in a lower bun 15 which is ligated by an appropriate link 16.
  • the transverse weld 12 extends over approximately 150 cm of the width of the mouth of the bag 8 while the longitudinal weld 13 extends over approximately 50 cm. It is easily understood that the transverse seam 4 of the mouth of the container 1 is carried out over the entire width without taking the bag 8 in said seam 4.
  • This mouth of the container 1 is assembled and ligated by one or more links or by a canvas band shown schematically in 17.
  • the tubular part 10 of the bag 8 is pulled through the lateral opening 7 to form a filling chute into which, during filling of the product 19, a filling nozzle 20 is inserted.
  • the filling is carried out according to the direction of arrow 21 in fig. 2.
  • the chute 18 is closed after filling the product 19 by means of a node 22 before being returned to the interior of the container 1.
  • the container 1 is filled by suspending the container 1 by its mouth ligated to the hook 23 of the station.
  • the chute 18 constituted by the tubular part 10 of the bag 8 is threaded around the filling nozzle 20.
  • the chute 18 After filling and the time necessary for deaeration of the product 19, the chute 18 is knotted by a simple cow knot made manually and is returned inside the container 1. The tightness of the container 1 at the mouth is thus total .
  • the presentation of the container 1 at the filling station and the closing of the bag 8 require a much shorter time than with the containers which present, at the mouth, a large volume of sheath or know how to handle.
