  • the present invention has for its object to overcome these disadvantages of known portable devices for dispensing granules, in particular flowable bulk material.
  • the inventive portable spreader for storing and dispensing granules includes a container for receiving the granules, a hose connected to the flexible hose, and arranged at the free end of the hose distributor with a flow regulator for metering the flow rate of the spreading material to be applied.

  • the granules are thrown out of the distributor and so evenly applied to the ground.
  • the flexible hose allows the distributor to swing back and forth without the container being swiveled. The application of the granules takes place without much effort, since the container and its contents with a shoulder strap is worn and to hold by hand only the hose end with the manifold.
