Definitions

  • the present invention relates to a device for fastening a valve to a flexible container, comprising an inner flange with a central opening provided with fastening means, and an outer flange with a central opening.
  • Elongated containers intended to be transported in freight con ⁇ tainers are often manufactured in sizes from 10 / 000 to 15,000 litres.
  • the container comprises an outer part formed by a durable plastic fabric and an inner part - formed by an inner bag of a thin plastic film.
  • the in- ner part of the container is disposable while the out ⁇ er part is returned to the supplier in folded state.
  • Such containers usually comprise two valves which are fastened both to the outer and the inner part and of which one is positioned in the upper portion of the container and the other in one end surface of the container close to the bottom plane. Through the upper valve the container is filled with and evacuated from air in connection with the filling, while the lower valve is used for filling the container with liquid and for emptying it, respectively.
  • valves For fastening the valves to the container, it is known to secure a flanged pipe in a hole formed in the outer and inner part.
  • the outer part is welded to the flange of the pipe whereas the inner part is drawn through the pipe, folded back to the outside of the pipe and fastened in place by means of a clamp. There ⁇ after the valve is fastened to the pipe.
  • the object of the present invention is to pro ⁇ vide a device for fastening a valve to a flexible con ⁇ tainer, which device can be fastened to the material of the container simply and reliably.
  • the device ac- cording to the invention is characterized by a con ⁇ necting socket the inner end of which is provided with fastening means arranged to be engaged with the fas ⁇ tening means of the inner flange and comprising a shoulder arranged to be positioned against the outer flange so as to press it against the inner flange, the container material being positioned between the flanges.
  • the device according to the invention enables the valve to be fastened to the container material in a simple and reliable way.
  • the device according to the invention thus comprises two flanges which can be pressed against each other by means of a connecting socket to which the valve is attached.
  • the contain ⁇ er material i.e., the inner and outer parts
  • the device will be fas ⁇ tened to the container when the flanges are pressed against each other.
  • the device is fastened to the con ⁇ tainer material rapidly and simply as well as fully mechanically without the use of welds.
  • the valve opening is surrounded on the inside of- he inner part by a rigid flange, there is no risk of the opening being clogged.
  • the outer surface of the inner flange and the inner sur ⁇ face of the outer flange are such in shape that when the flanges are positioned against each other, at least one ring-shaped space is defined between the surfaces for a flexible ring positioned against the container material. The container material is thus fastened to the flanges by form locking.
  • the inner part of the container can be advanta ⁇ geously connected to the device according to the in ⁇ vention in such a manner that the outer surface of the inner flange is provided with a ring surface parallel with the central line of the opening and provided with threads, and that the device comprises a nut to be fastened to the ring surface.
  • a ring connected to the container material can thereby be fastened between the outer surface of the inner flange and the end surface of a nut attached to the inner flange.
  • the shoulder of the connecting socket is formed by the end surface of a nut which is fastened with threads to the connecting socket and the outer diameter of which exceeds the diameter of the opening of the outer flange.
  • FIG 2 is an exploded view of one half of the device.
  • the device according to the invention shown in the drawing comprises an inner flange 1 provided with a central opening 2 and an outer flange 3 similarly provided with a central opening 4. Both flanges pre ⁇ ferably have the shape of a round plate, and they can be made of stiff plastic, for instance.
  • the device comprises a connecting sock ⁇ et 5 in the outer end of which the valve is mounted.
  • the container to which the valve is to be attached comprises an outer part 6 of a coarse and durable plastic fabric and an inner part 7 of a thin dis ⁇ posable plastic film. It appears from Figure 1 that the inner flange 1 is positioned within the container wall and the outer flange 3 outside the container wall.
  • the wall in the central opening 2 of the inner flange is provided with threads 8 and the outer sur ⁇ face of the inner end of the connecting socket 5 is likewise provided with threads 9 which are engageable with the threads 8.
  • the connecting socket 5 comprises in the mid portion thereof a shoulder 10 which in the shown embodiment is formed by an end surface of a nut 11 fastened to the connecting socket by means of threads 12 provided thereon.
  • the outer diameter of the nut 11 and, as a consequence, that of the shoulder 10 is greater than the diameter of the central opening 4 of the outer flange, and the shoulder 10 is thus positioned against the outer surface of the flange 3 within the area around the opening 4 when the device is assembled as shown in Figure 1.
  • the ring surfaces of the flanges 1, 3 which are to be positioned against each other are not planar; instead, they are so shaped that a ring-shaped space 14 is defined between the surfaces when the flanges are positioned against each other.
  • This space 14 is formed by a recess in each flange.
  • the recesses are indicated with the reference numerals 15 and 16.
  • the inner flange 1 is further provided with a projecting ring-shaped member 17 which surrounds the central opening 2.
  • the outer surface of the projecting member is provided with threads 18 which are engage- able with threads 19 on a pinching nut 20 which thus can be screwed on to the projecting member 17 in such a way that one end surface of the nut 20 is positioned against the outer surface of the flange 1.
  • rings 21 and 22 of a flexible material are po- sitioned in the space 14 and between the end surface of the nut 20 and the flange 1, respectively, and the outer part 6 of the container is inserted in the space 14 and the inner part 7 in between the nut 20 and the flange 1.
  • the flexible ring 22 is positioned in place around the projecting member 17 of the flange 1 and the projecting member 17 is pushed from within the container through the opening in the film 7, whereby the film is positioned against the ring 22 as shown in Figure 2.
  • the inner part of the container will be locked in the inner flange 1.
  • the ring 21 and the edge of the outer part 6 of the container is there- after positioned in the recess 15 of the inner flange, whereafter the outer flange 3 is positioned on the in ⁇ ner flange, so that the ring 21 will be positioned in the substantially closed space 14.
  • the in ⁇ ner end of the connecting socket 5 can be inserted in the central openings 2, 4 of the flanges, finally by screwing the connecting socket so that the threads 8, 10 are engaged with each other.
  • the shoulder 10 will be positioned against the outer surface of the flange 3, so that all the three parts, i.e., the flan ⁇ ges 1, 3 and the connecting socket 5 will be locked together while the container material 6, 7 is locked in place between the flanges.
  • the compression press- ing together the flanges can be adjusted by screwing the nut 11 outwards or inwards.
  • the valve is attached to the outer end of the connecting socket 5.
  • the nut 11 can be optionally omitted as well as the nut 20.
  • the shape of those surfaces of the flanges 1, 3 which are to face each other may also differ from that shown in the figures.

Abstract

L'invention concerne un dispositif permettant de fixer une vanne sur un récipient souple. Les dispositifs antérieurs dans ce domaine comprennent un tube auquel les couches interne et externe dudit récipient sont fixées, par exemple par soudage et à l'aide de fixations. Les soudures altèrent le matériau. On peut parer à cet inconvénient au moyen d'un dispositif comprenant deux brides (1, 3) entre lesquelles on passe le matériau du récipient (6, 7) et qui sont fixées ensemble à l'aide d'une douille de raccordement (5) pressant la bride externe (3) contre la bride interne (1) à laquelle ladite douille (5) est fixée de manière amovible.
