Description

  • The invention is related to a container for liquids or particulate bulk material comprising a container of cardboard, fibers or similar rigid material with its bottom supported by a pallet, in which container an inner bag of plastic material is present, which container is provided in the region of the bottom thereof with drain means comprising a valve housing with valve operating means, which housing is provided with a neck extending through aligned openings in the inner bag, the bottom and the pallet, the connection of the neck to these openings being sealed by clamping the edges of the openings of the bag, the bottom and the pallet together with one or more sealing rings between a flange or edge of the housing located within the bag and a clamping ring positioned on the housing below the pallet.
  • Such a container is known from Dutch laid open patent application 7008018. In this known container the neck of the valve housing fits in the openings of the bag, the bottom and the pallet, which openings all have the same diameter. Between the edge of the opening of the bag and the edge of the bottom opening a sealing ring of the O-ring type is clamped.
  • The sealing of this known container in a number of circumstances presents difficulties. Under rough handling or toppling of the container the problem arises that by displacement of the contents, in particular when this is a liquid, the container deforms and high tensions develop in the inner bag at the place where this is fixed near the drain means. This may result in tearing of the inner bag by which serious leakage occurs.
  • The aim of the invention is to provide a construction in which this problem no longer arises without being obliged to make use of obvious but more expensive solutions, such as the application of a stronger inner bag and a stronger clamping of stronger sealing rings.
  • This aim according to the invention is obtained by the fact that the edge of the opening of the bottom along the whole inner circumference is provided with radial incisions for forming tongues of which the bases lie on a circle of diameter approximately equal to that of the hole in the pallet and greater than the outer diameter of the neck of the valve housing, which tongues are bent downwardly and with their ends rest on an edge or shoulder or a ring fixed on the neck, and the edge of the opening of the bag is passed between the container bottom and the flange and extends to the neck around a seal clamped between a ring and the valve housing, which seal also encloses the edge of the bag extending downwardly along the neck. The tongues formed in the edge of the opening of the bottom now form so to speak a cone-shaped support edge, which ensures that under all circumstances relative movements between the valve housing and the container bottom cannot take place. Under extreme heavy support conditions and toppling of the container, however, the valve housing can move upwardly with regard to the pallet and follow so to say the moving inner bag, by which high tear forces and tearing of the inner bag are avoided. Indeed the bottom may come loose of the pallet, but the clamping of the bag between the sealing ring and the valve housing remains.
  • Now the invention will be elucidated with the aid of the drawing.
  • This shows schematically in section the principle of the invention. The drawing shows a pallet 1 with an inner opening 2. Herein a valve housing 3 extends of which the construction essentially may be the same as that shown in Dutch patent application 7008018, which valve housing has a neck 4.
  • The bottom 5, which is of corrugated cardboard has an opening of which the edge is formed by tongues 6 that in a known matter can be obtained by means of radial incisions. These tongues 6 rest with their lower ends 7 on a shoulder 8 of a clamping ring 9 mounted on the neck 4. The inner bag 10 rests on the bottom 5 and is at the place of the flange 11 enclosed between the bottom 5 and this flange.
  • The bag extends to the neck 4 and subsequently downwardly along the neck 4 until the clamping ring 9 and thereby encircles a sealing ring 12 that encloses the neck and the inner bag and that is clamped between the lower side of the flange 11 and the clamping ring 9.
  • In case the housing by any cause is moved upwardly with regard to the pallet 1 in the first place the tongues are deformed and in a later state possibly the container bottom may come loose of the pallet, but the connection of the bag with the valve remains undamaged by which leakage is avoided.
