The Procona system is a package
being made up of a plastic container, a cardboard collar
which fits the container and lid with many openings. The
package is developed in such a way that the flowers keep
their quality during transportation.
The costumer can clearly see
the colour of the flowers through the lid. The corners of
the lid are very stiff and strong by means of ribs. Ridges
have been made on the lid, so that the package cannot shift,
when stacked on the lid.
When stacked, a following
container does not completely shut off the lid. There are
30 ventilation openings in the lid. The water vapour can
escape the package. the cold air can enter. These ventilation
openings are important to preserve the quality of the flowers
during transportation and storage.
