Definitions

  • the invention relates to a transport container for liquid containers, in particular for transporting bottles in an aircraft, with an internal liquid absorber made of an absorbent material and covering at least part of the lower region of the transport container.
  • the transport containers consist of a light material that is not or not permanently liquid-resistant
  • a damaged liquid container can prove to be damaging to the entire freight without further safety precautions.
  • the content of a damaged liquid container in or outside the cargo space can cause damage, depending on the chemical aggressiveness of the liquid.
  • the absorbency is relatively low, a lot of absorbent padding material has to be arranged, which increases material and labor costs. Furthermore, what has a negative effect, especially when transported by plane, must be a lot with a low leak rate Bai 1 astmateri al be transported.
  • the retention of the absorbent material is relatively low. In the event of a transport-related pressure load from full, undamaged bottles, the liquid absorbed by the absorbent material is squeezed out again.
  • the inventor has therefore set himself the task of creating a transport container for liquid containers of the type mentioned at the outset, which contains absorbent materials of higher absorption and retention capacity, with lower volume and weight.
  • This material should be inexpensive to procure, easy to process and easy to dispose of.
  • the object is achieved in that the absorbent material during the transport of aqueous liquids comprises a homogeneously mixed, hydrophilic pulp made of cellulose-containing fibers, which at many points are connected to fibers made of at least one thermoplastic by hot melt adhesive and a net-like one Form a structure of increased strength with an incorporated superabsorber, and / or the absorbent material when transporting oily liquids consists of a hydrophobic pulp of intertwined and hooked polyolefin fibrils.
  • Superabsorbers introduced into suction pads for aqueous liquids are known, for example, for the production of hygienic articles such as diapers.
  • Superabsorbents are highly absorbent polymers which can bind a multiple of their weight in water or aqueous liquids and thereby form a gel which remains stable even under pressure.
  • This high shark teverm ⁇ gen, Retention, also called retention is a particularly important property, so that the aqueous liquid is not squeezed out again when pressure is exerted by full, undamaged liquid containers.
  • the suction speed of a superabsorbent of a given composition and surface properties is mainly dependent on its grain size, i.e. in the case of smaller grains, the total active area of the superabsorber is larger, and therefore the absorption or gel formation takes place much faster.
  • the setting of the absorbency of a pulp is achieved with different types of superabsorbers and / or different amounts of superabsorbers.
  • superabsorbents are commercially available.
  • Transport containers for liquid containers with a thermally bonded pulp as described above and sprinkled superabsorber can be many times, e.g. absorb up to 50 times its own weight in aqueous liquid. Therefore, only little absorbent material has to be placed in the transport container and transported as a load when not in use.
  • cell-based recycling fibers are preferred as the basic structure. Recycling material, in particular made of paper and / or textiles, is defibrated in a manner known per se. The process corresponds in principle to the shredding of wood chips obtained from logs in a devibrator.

  • these plastic fibers have the following advantageous properties:
  • the net-like structure of increased strength of the absorbent material according to the invention for aqueous liquids in transport containers takes place in that the homogeneous mixed cell-containing fibers and plastic fibers until the plastic melts to a slightly lower temperature lying below the combustion temperature of cellulose are heated, and the superabsorbent is sprinkled in before or after the heating.
  • the heat treatment temperature for melting the plastic fibers in the materials used is preferably in the range from about 160 to 220 ° C.
  • the plastic ashes may only melt to such an extent that they form connection points with the cellulose-containing fibers. However, they must not melt through.
  • the temperature is applied for a correspondingly short period of time, which can be determined in simple tests.
  • the temperature required for thermal bonding is preferably determined by means of a hot air flow introduced into the forming cavities or by means of at least one shaped heating surface, e.g. designed as a heating bed, heating roller or wandering, endless heating tape, which means enable a metered application of heat.
