Definitions

  • the present invention concerns improvements in or relating to containers, especially but not exclusively containers in the form of bags adapted for the transportation and storage of materials in bulk, for example, bags capable of containing loads of one tonne.
  • bags of this nature contain foodstuffs or other materials which can readily be contaminated.
  • the bags may be designed for single use or multiple use and are normally fabricated in the form of a general rectangular prism having a substantially flat base, from natural or synthetic fabric, typically woven polypropylene.
  • the bags are often designed so that they can be discharged automatically and to this end have an aperture in their base through which the contents of the bag can be ejected.
  • the contents are sometimes contained within the bag by a rupturable plastics material membrane extending across the base of the bag, which membrane can be provided by the base of an internal plastics material lining member.
  • a container for fluent materials including a base member in which is provided a discharge aperature and, a sheet member for attachment to the exterior of the base over said aperture said sheet being affixed to the base by a removable adhesive whereby prior to discharging the bag's contents it can stripped from the base of the container.
  • the container is fabricated from woven polypropylene in the form of a rectangular prism.
  • the sheet is formed from woven polypropylene and has the same configuration but lesser dimensions than the container base.
  • adhesive is provided around the entire periphery of the sheet and is of a type which permanently adheres to the sheet but temporarily adheres to the base whereby on removal of the sheet the adhesive is removed also.
  • the sheet may be manufactured from rigid material to give the container a rigid temporary base.
  • the temporary base may include means for facilitating mechanical handling.
  • the bag of the present invention comprises four upstanding sides 10 with a rectangular top (not shown) and a rectangular base 12 fixed thereto by any suitable means, for example, stitching.
  • Lifting handles 14 are provided at the top of the bag but as they do not form part of the present invention they will not be described in any detail.
  • the bag is manufactured from panels of woven polypropylene stitched together but any alternative material and construction technique may be employed.
  • the base of the bag has a discharge aperture 16 which, conveniently, is circular.
  • a base membrane (not shown) which may either be a separable membrane positioned on the inside of the base of the bag or alternatively the base of a plastics material lining the entire bag.
  • a removable flap 18 conveniently of woven polypropylene, which has a shape conforming to the shape of the base but is of lesser dimensions.
  • strip of adhesive 20 is provided along the entire length of each edge of the removable sheet 18, the adhesive being applied by any suitable mechanical or manual means and being a cold or hot melt adhesive whose properties are such that its attachment to sheet 18 is greater than its attachment to the base 12 of the container to which the removable sheet is attached.
  • the removable sheet as well as adding strength to the base of the container, especially across the aperture 16, provides an impermeable barrier, to dirt, bacteria, insects, vermin etc over the base area it covers and also protects the regions of the base of the bag surrounding the aperture from abrasion damage.
  • Fig. 2 shows a modified bag in which the sheet 18 is similar to the sheet illustrated in Fig. 1 but has adhesive 20 on only three of its edges the remaining edge being attached permanently to the base by, for example, stitching 22.
  • the stitching may be that employed to attach the base 18 to the side panel.
  • the container need not be a bag but could be a rigid container. It could have any suitable shape and any number of apertures in the base. Alternatively there may be no aperture in the base where it is intended that the base is ruptured to permit discharge.
  • the protective sheet may not be manufactured from woven polypropylene but could be a flexible plastics sheet or, as illustrated in Fig. 3, a rigid sheet 24. If the latter, the rigid sheet 24 may incorporate mechanical handling means, for example, channels 26 for the tines forklift trucks.
  • a rigid covering sheet could be manufactured from wood or more suitably from rigid plastics material.
  • the covering sheet need not conform to the shape of the base but could have any suitable shape, provided that at least the aperture in the base or the discharge area in a non-apertured base is protected. Obviously it is important that the adhesive strip is continuous and that any suitable adhesive may be employed.
  • the adhesive may be applied in the form of a double sided tape that is with the adhesive on one side adhering to the sheet and that on the other side adhering less strongly to the base. A single sided adhesive tape could be used. In this case the tape would be applied such that its inner portion adhered to the sheet at its periphery while its remaining outer portion adhered to the bag.
  • projecting tabs or strips with no adhesives may be provided at the periphery of the sheet to provide a hand hold for an operative removing the sheet.
  • the sheet may have dimensions greater than the base so that it extends over the lower regions of the sides and is fixed by adhesive to the sides rather than the base.
  • the aperture in the base of the bag may have an externally projecting discharge tube connected to it.
  • the discharge tube is normally sealed off by tying it around with tapes and, of course, in the transport and storage condition the tube would also be protected by the adhesive sheet.
  • the bag can be utilised in an alternative orientation, for example, with the base displaced by 90° so that side discharge is then achieved.
