"Ski bag or ski bag made of plastic for storing or transporting skis

The present invention relates to a ski bag or ski pouch made of plastic for storing or transporting skis. The ski bag according to the invention is intended to serve as a means of transport and storage and at the same time largely avoid or prevent rusting or corrosion of certain metal parts of the ski, for example corrosion of the ski edges. It is already known to use plastic boxes with closure parts for storing or transporting skis. These plastic boxes have a considerable width and height and are particularly suitable for transport on motor vehicles and the like.

The aim and object of the present invention was to find a transport and storage means made of plastic that differs from a box shape for storing or transporting skis. The packaging or storage means should be easy to transport and reduce or largely reduce the corrosion of the metal parts of the ski.

According to the invention, it was found that these aims and tasks are met by a ski bag or ski bag made of plastic for storing or transporting skis, which is provided with a closure or a closure element. The wall thickness of the ski bag according to the invention is 60 to 500 μm, preferably 100 to 400 μm. The ski bag
