ABSTRACT:
The invention is a floral foam base made of hydrophilic or hydrophobic plastic foam for the arrangement of natural flowers, twigs, branches, fruits as well as decoration material, providing the foam base with a waterproof coating made of resins and lacquers.
Such a floral foam base will be combined with a bowl or other plastic fixings after shaping as desired, e.g. bars, spheres for bouquet holder, wreathes, etc. In most cases wire cages or other fixings are used to connect the floral foam and the bowl. Instead of plastics bowls or cages parts of biodegradable material will be used.
The main disadvantage of these well-known types is, that for the various shapes the corresponding molds must be available which causes considerable costs. Additional work is necessary to connect the foam bases with the bowls.
The subject matter of the invention is to create such a foam base in that way that an additional fresh water supply guarantees long freshness of natural plants.
This problem will be solved by a water storage space on the bottom area between coating and floral foam, connected with the outside by a filling pipe.
It is also an advantage to provide the foam base with a concavity within the non-coated area.
The invention especially has the advantage to have a one-piece product with high stability of the connection. All shapes and sizes can be manufactured easily by cutting and sawing. The entire product is biodegradable and is stabilized by the coating.
