Benefits of technology

[0012] The present invention provides a novel cut plant container for providing liquid to a cut flower wherein a substantial amount of the liquid required by the plant is presented to the cut end of the plant stem for preserving the life of a cut flower.
[0016] It is still another object of the invention to provide a horticultural container for cut flowers which can be economically fabricated to fit a wide variety of stem bunch sizes.

Problems solved by technology

As the stem bends, the flower head droops and the flow of water up the stem is impeded.
Soon afterwards, the flower petals start to discolor and the flower dies.
In shipping the cut flowers are often stored under uncontrolled temperatures which can cause dehydration and destruction of lots or individual flowers.
Even when such precautions are taken, cut flowers start to wilt after a few days.

Embodiment Construction

[0025] The preferred embodiment and best mode of the invention is shown in FIGS. 1 through 6.

[0026] The invention is directed toward a rectangular shaped foam member 10 formed of an aromatic polyisocyanate polymer diphenylmethane diisocyanate (MDI) flexible foam material using no filler material which hydrates cut flowers in shipment by directing water absorbed in the foam wrap to the stems.

[0027] The polyisocyanate used in the foam material is an aromatic polyisocyanate which includes aromatic diisocyanates having 6 to 16 carbon atoms (excluding those contained in NCO groups; this applies to the polyisocyanates mentioned below), aromatic triisocyanates having 6 to 20 carbon atoms and crude products of these isocyanates, etc. Examples of aromatic polyisocyanate include 1,3- and 1,4-phenylene diisocyanates, 2,4- and / or 2,6-tolylene diisocyanates (TDI), crude TDI and 2,4′- and / or 4,4′-diphenylmethane diisocyanate (MDI) as well as crude MDI.
