Abstract
Description
- The application is a continuation-in-part of U.S. patent application Ser. No. 10/670,531 filed on Sep. 26, 2003.
- The present invention relates generally to the use of a bag wrap for transporting cut flowers and plants. More particularly, this invention relates to a plastic bag having an internal cup shaped stem wrap formed of polyisocyanate foam material using diphenylmethane diisocyanates which holds flower stems and is secured with a strap which is secured around the bag.
- I. Field of the Invention
- The present invention relates generally to floriculture. In particular, the present invention relates to a device and method for holding the stems of cut flowers during shipment and hydrating the flowers.
- II. Discussion of Background
- The flower industry is a multi-billion dollar industry worldwide. In the U.S. alone, sales of cut roses exceed hundreds of million dollars per year. The most popular varieties of rose often retail for several dollars per rose. Sales of other cut flowers and plants such as bamboo are also substantial.
- It is a common practice to sustain the life of cut flowers by means of inserting the end of the plant stem in a reservoir containing a liquid such as water. Flowers start to wilt just a few hours after cutting unless they are supplied with water and nutrients. The first indication of wilting is when the stem starts to bend just below the flower head. 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 shipment from the grower, cut flowers are generally wrapped in newspaper or shredded paper or fiber and covered with a paper or plastic sleeve. In shipping the cut flowers are often stored under uncontrolled temperatures which can cause dehydration and destruction of lots or individual flowers.
- Many techniques are available for extending the useful life of cut flowers, including changing their water regularly, adding preservatives to the water, trimming the stems, keeping the flowers away from direct sunlight, and refrigerating them. Even when such precautions are taken, cut flowers start to wilt after a few days.
- A number of devices have been used for supporting and shipping cut flowers. For example, a spacing disc for a conical paper flower container having a plurality of spaced tear-shaped openings for holding flower stems as is shown by U.S. Pat. No. 3,767,104 issued Oct. 23, 1973. Flowers can be fixed to a continuous strip, which is then rolled in such a fashion that the flowers are isolated from one another to facilitate storage and transport as is shown by U.S. Pat. No. 3,657,840 issued Apr. 25, 1972. Holders for cut flowers include a flexible paper cover for protecting the flower petals as shown by U.S. Pat. No. 3,271,922 issued Sep. 13, 1966 and a cardboard sleeve for receiving the stems as shown by U.S. Pat. No. 2,247,191 issued Jun. 24, 1941. A waterproof wrapper for corsage stems is shown by U.S. Pat. No. 1,044,260 issued Nov. 12, 1912.
- There is a need for a simple, easy-to-use container for cut flowers which keep the flowers hydrated during wholesale shipment and/or delivery from the florist to the end user. The container should not damage the stems of the flower when wrapped and should hold the stems firmly, allowing air water and nutrients to contact each stem and be simple and inexpensive to manufacture.
- A plastic bag with an inner base of shaped foam material is wrapped over the cut ends of the stems of cut flowers to form a wrap covering the stems. The wrap is held in place with a plastic strap which is wrapped around the outer bag over the ends of the stems. The inner base portion of the wrap is constructed of a sterile diphenylmethane diisocyanate (MDI) foam material having at least 50% of its pores ranging in size from 10 to 200 microns. If desired the foam material can be of an organic polyisocyanate foam material using one or more of crude, polymeric, 4,4′-, 2,4′- and 2,2′-diphenylmethane diisocyanates with a soy based polyol ranging from 10% to 25% having a low density. The bag is inverted so that the foam material is positioned outside the bag and is dipped into water and nutrient, and the stems are placed into the base and the bag is then pulled over the base and stems and held securely with a strap.
- 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.
- It is an object of the invention to provide a horticultural container for cut flowers having a homogeneous horticultural foam material base which is sterile.
- It is another object of the invention to provide a horticultural container for cut flowers which hydrates flowers in shipment.
- It is yet another object of the invention to provide a horticultural container for cut flowers which directs water held in the foam to the stems.
- 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.
- It is another object of the invention to provide a horticultural container for cut flowers which can be easily applied by the shipper or florist to bunches of cut flowers.,
- These and other objects, advantages, and novel features of the present invention will become apparent when considered with the teachings contained in the detailed disclosure along with the accompanying drawings.
