Abstract

The invention is dealing with a sack (1), a bag or similar packing for moisture containing products. The plastic wall (1) of the sack is provided with a plurality of micro-holes, and a moisture absorbing member (4) is arranged within the sack.

Description

  • The aim of the invention is the use of a sack, bag, or the like, for moisture containing root vegetables.
  • For the storage, transport and packaging of moisture containing products, different types of bags and sacks are used, the material of their manufacture often being a plastic membrane by reason of costs. Such a sack, however, is often so tight that the product in the bag does not keep very long without getting spoiled. Again, if a breathing material is used, such as fabric or porous paper, the bag will easily get wet and moisture will be able to penetrate into the interior of the sack and spoil its contents.
  • From Patent Abstracts of Japan, Vol.13, No.498, M-890, abstract of JP-A-1-199 878, a package is known formed from a heat-sealable, water-impermeable sheet having small orifices; said package is provided with a water absorbing body and is used for packaging medical supplies.
  • The aim of the present invention is the use of a sack, or a corresponding packing or bag, to preserve moisture containing root vegetables for a longer period of time, wherein the bag does not necessarily have to be protected from rain or exterior moisture.
  • Accordingly, the invention is directed to the use of a plastic sack, cover, or similar packing according to claim 1.
  • The micro-holes are quite small holes made in the wall of the sack, through which moisture from the interior of the sack is able to escape into the surrounding atmosphere, but rain-water, for instance, is not able to penetrate into the interior of the sack. In addition a moisture absorbing member is provided within the sack, so that collection of moisture inside the sack, which would spoil the contents of the sack, is not possible.
  • The moisture absorbing member used in the sack preferably is silicate, e.g. vermiculite, or similar moisture absorbing material, contained in a perforated bag.
  • The invention is described in more detail in connection with the enclosed drawing which presents one working example of the invention.
  • The figure presents a sack 1 made of plastic tubing with a bottom seam 2. The bag membrane is perforated by a plurality of micro-holes 3, the perforation of which is carried out either in the step of producing the tube, or in the step of producing the bag.
  • In the interior part of the sack a detached perforated bag 4 is placed, which contains a moisture absorbing material such as vermiculite. Naturally, also other moisture absorbing materials may be used.
  • In the working example presented, a detached bag 4 is used inside the sack. Naturally, also other solutions may be adapted in placing the moisture absorbing material into the interior of the sack.
  • The size of the sack 1 or the bag may vary. For packing and transport packing of various root vegetables, its size may be 30 - 50 litres, or even larger. In a sack like this potatoes or other roots may be preserved for even greater lengths of time, the moisture contained in the roots not collecting in the inner parts of the sack spoiling the roots, but escaping through the micro-holes 3. In addition, the sacks may be stored even in the outer atmosphere, because the sack is made of plastic material which stands moisture well, contrary to conventional jute sacks, for instance. In addition, the holes made in the plastic membrane are so small in size that rain, for instance, is not able to penetrate through them into the interior of the sack.

Claims (2)

  1. Use of a plastic sack (1), cover, or similar packing having walls (1) provided with a plurality of micro-holes (3) such that moisture from the interior of the sack, cover, or similar packing is able to escape into the surrounding atmosphere, a moisture absorbing member (4) being provided inside the sack, cover or packing, characterised in that the sack, cover, or similar packing, is used for the storage, transport and packaging of moisture containing root vegetables.
  2. Use of a plastic sack (1), cover, or similar packing, according to claim 1, characterised in that silicate, such as vermiculite or a corresponding moisture absorbing material, contained in a perforated bag (4) is used as the moisture absorbing member (4).
