Compressed expandable floral arrangement mechanics and methods

1 . A floral arrangement product comprising:

a pouch comprising two or more sides sealed at their perimeter, wherein at least one of the sides comprises a membrane;

an expandable medium in a compressed state fully enclosed within the pouch, and wherein the expandable medium is configured to expands upon hydration and fills the pouch;

wherein the membrane at least partially envelops the expandable medium and is configured to remain intact and be tightened upon expansion of the expandable medium and to form a rigid dome structure and that is pierceable by plants and/or flower stems;

wherein the expandable medium comprises wood or coir compressed in pellets, bricks or granules and has a fill amount that is sufficient upon expansion of the expandable medium to tighten and keep the membrane intact and to form the rigid dome structure while maintaining a residual compression in the expandable medium, and wherein the combination of the tightened intact membrane and the residual compression of the expanded expandable medium supports and holds the inserted plants and/or flower stems in an arranged position and in any orientation.

2 . The product of claim 1 , wherein the membrane consists of a Poly Lactic Acid (PLA) based polymer.

3 . The product of claim 1 , wherein the membrane comprises one of wax paper fibers, or cotton based textiles.

4 . The product of claim 1 , wherein the membrane comprises a thickness in the range of 10 micrometers to 60 micrometers.

5 . The product of claim 1 , wherein the membrane comprises pre-perforated openings.

6 . The product of claim 1 , wherein the membrane comprises a water permeable membrane.

7 . The product of claim 1 , wherein the membrane comprises a perforable membrane.

8 . The product of claim 1 , wherein the pouch comprises a top side, and a bottom side and wherein said top and bottom sides are sealed at their perimeter.

9 . The product of claim 1 , wherein the fill amount of the expandable medium is calculated by:

Vf

=

Vm

*

Cr

/

Em

,

wherein

Vf=Fill volume of compressed expandable medium,

Vm=Maximum volume available inside the pouch without tightening the membrane,

Cr=Residual compression coefficient,

Em=Vw/Vd, wherein

Vw=wet volume of nominal amount of expandable medium fill once it stops absorbing water,

Vd=dry volume of the nominal amount of expandable medium fill before hydrating with water.

10 . The product of claim 1 , comprising a plurality of pouches detachably attached to each other and arranged in linear, circular, two-dimensional or three-dimensional structures.

11 . A method for a floral arrangement comprising:

providing a pouch comprising two or more sides sealed at their perimeter, wherein at least one of the sides comprises a membrane;

providing an expandable medium in a compressed state fully enclosed within the pouch, and wherein the expandable medium expands upon hydration and fills the pouch;

hydrating the compressed expandable medium and causing it to expand, and wherein the membrane remains intact and is tightened upon expansion of the expandable medium and forms a rigid dome structure that is pierceable by plants and/or flower stems; and

inserting plants and/or flower stems into the expanded expandable medium through the rigid dome structure of the membrane; and

wherein the expandable medium comprises wood or coir compressed in pellets, bricks or granules and has a fill amount that is sufficient upon expansion of the expandable medium to tighten and keep the membrane intact and to form the rigid dome structure while maintaining a residual compression in the expandable medium, and wherein the combination of the tightened intact membrane and the residual compression of the expanded expandable medium supports and holds the inserted plants and/or flower stems in an arranged position and in any orientation.
