Abstract

Abstract The disclosed method and apparatus include steps and means for providing a supply of aqueous nutrient liquid to the cut end of each of one or more cuttings such as cut flowers and small branches for sustaining life processes, and for coupling the cut interface of each such cutting to the liquid supply. The lateral surface of each cutting is usually covered at and adjacent the cut end. This covering inhibits contamination and deterioration of the nutrient liquid during protracted periods of growth. For many kinds of cuttings, the nutrient liquid is applied to the ends of the cuttings at a distinctly higher pressure than that which is present incidentally at the cut ends of flowers in a vase.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 163 words
A method of sustaining life processes of a cutting such as a living branch or flower, including the steps of providing in a collapsible reservoir a wholly enclosed supply of liquid suitable for maintaining viability of said cutting and conducting the liquid through an unobstructed liquid delivery and coupling means to essentially all of the cut end of the cutting, the liquid delivery and coupling means including an elastic sleeve of water-impermeable material at the delivery end thereof remote from the collapsible reservoir, and applying said resilient sleeve in tension about all of that portion of the lateral surface of the cutting which is at and adjacent to the cut end of the cutting for forming a leak-preventing cover thereon and the resilient sleeve having a portion extending beyond said cut end, such that only the cut end of the cutting is in contact with the liquid in the extending portion of the elastic sleeve, said reservoir collapsing as the cutting absorbs liquid.
Claim 2
Independent Claim 163 words
A method of sustaining life processes of a cutting such as a living branch or flower, including the steps of providing in a collapsible reservoir a wholly enclosed supply of liquid suitable for maintaining viability of said cutting and conducting the liquid through an unobstructed liquid delivery and coupling means to essentially all of the cut end of the cutting, the liquid delivery and coupling means including an elastic sleeve of water-impermeable material at the delivery end thereof remote from the collapsible reservoir, and applying said resilient sleeve in tension about all of that portion of the lateral surface of the cutting which is at and adjacent to the cut end of the cutting for forming a leak-preventing cover thereon and the resilient sleeve having a portion extending beyond said cut end, such that only the cut end of the cutting is in contact with the liquid in the extending portion of the elastic sleeve, said reservoir collapsing as the cutting absorbs liquid.
Claim 3
Dependent Claim 23 words
The method in accordance with claim 1, further including the step of developing positive fluid pressure at the cut end of the cutting.
Claim 4
Dependent Claim 55 words
The method in accordance with claim 1, further including the step of maintaining a confined volume of liquid at the cut end of the cutting having an average transverse dimension no greater than about twice that of said cut end and a minimum length about equal to the average transverse dimension of said confined volume.
Claim 5
Dependent Claim 35 words
The method in accordance with claim 1, including the step of adjusting the relative level of the reservoir and the cutting to maintain a small negative fluid pressure at the cut end of the cutting.
Claim 6
Dependent Claim 53 words
The method as in claim 1 including the step of implanting a portion of the cutting extending from the leak-preventing cover in moist material suitable for root growth so that a cutting can be sustained during an extended period of time to enable roots to develop from said extending portion of the cutting.
Claim 7
Dependent Claim 124 words
In combination, a live cutting and means for supplying liquid to the cut end of the cutting, said supplying means including a collapsible reservoir of liquid suitable for maintaining viability of said cutting and unobstructed liquid delivery and coupling means one end of which extends from the reservoir to essentially the entire cut end of the cutting, said delivery and coupling means including an elastic sleeve of water-impermeable material in tension about the cutting and forming a leak-preventing cover on the lateral surface of the cutting at and near its cut end and extending beyond its cut end, such that only the cut end of said cutting is in contact with liquid in said elastic sleeve, said reservoir collapsing as the cutting absorbs liquid.
Claim 8
Dependent Claim 124 words
In combination, a live cutting and means for supplying liquid to the cut end of the cutting, said supplying means including a collapsible reservoir of liquid suitable for maintaining viability of said cutting and unobstructed liquid delivery and coupling means one end of which extends from the reservoir to essentially the entire cut end of the cutting, said delivery and coupling means including an elastic sleeve of water-impermeable material in tension about the cutting and forming a leak-preventing cover on the lateral surface of the cutting at and near its cut end and extending beyond its cut end, such that only the cut end of said cutting is in contact with liquid in said elastic sleeve, said reservoir collapsing as the cutting absorbs liquid.
Claim 9
Dependent Claim 55 words
Apparatus in accordance with claim 6 wherein said liquid delivery and coupling means forms an open-ended chamber whose transverse cross-sectional area is a maximum of about four times the cross-sectional area of the cutting and whose length measured from the cut end is a minimum of about the average transverse dimension of the confined volume.
Claim 10
Dependent Claim 16 words
Apparatus in accordance with claim 6 including means providing positive fluid pressure at said cut end.
Claim 11
Dependent Claim 22 words
Apparatus in accordance with claim 6 wherein said reservoir includes a collapsible pouch closed against exposure of its contents to the atmosphere.
Claim 12
Dependent Claim 27 words
Apparatus in accordance with claim 9 further including means for applying a sustained pressure to said pouch despite gradual depletion for maintaining pressure in the liquid therein.
Claim 13
Dependent Claim 41 words
Apparatus as in claim 9, further including at least one additional cutting and one additional liquid delivery and coupling means all as aforesaid, each said liquid delivery and coupling means being individually connected to said pouch through a respective hole therein.
Claim 14
Dependent Claim 34 words
A combination as in claim 9, further including resilient means bearing against the pouch for sustaining pressure of the liquid against the cut end during depletion of the supply of liquid in the pouch.
Claim 15
Dependent Claim 32 words
A combination as in claim 9, further including means causing the cutting to apply its weight to the collapsible pouch for developing fluid pressure in the pouch and at the cut end.
Claim 16
Dependent Claim 38 words
Apparatus in accordance with claim 13, wherein said means is arranged to accommodate downward shift of the cutting as said upper wall portion of the pouch is allowed to descend by virtue of progressive depletion of the liquid.
Claim 17
Dependent Claim 19 words
Apparatus in accordance with claim 6 including means to provide a fluid pressure range extending from negative to positive.
Claim 18
Dependent Claim 28 words
Apparatus as in claim 6, wherein said liquid delivery and coupling means includes a manifold interposed therein, said manifold having plural outlets for a corresponding plurality of cuttings.
Claim 19
Dependent Claim 33 words
The combination as in claim 6, wherein said liquid delivery and coupling means further includes a tube extending into the portion of said sleeve that extends beyond said cut end of the cutting.
Claim 20

In combination, a live cutting, a collapsible pouch for containing liquid suitable for maintaining viability of the cutting, the pouch enclosing the liquid against exposure to the atmosphere, a sleeve of elastic water-impermeable material in tension about the cutting at and near the cut end thereof for forming a leak-preventing cover on the lateral surface of the cutting, said sleeve having a portion extending beyond said cut end to a point adjacent a wall of said pouch, and a tube having one end which extends into said extending portion of the sleeve and said tube having another end joined to a wall of the collapsible pouch and opening into the interior thereof, such that only the cut end of the cutting is in contact with liquid in said sleeve, and said pouch collapsing as the cutting absorbs liquid.
Claim 21
Dependent Claim 138 words

Claim 22
Dependent Claim 42 words
