Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 268 words
A method for forming a sheet of material into a flower pot or flower pot cover, the steps of the method comprising: providing a male die having a male die surface; providing a female die having an opening formed through a portion thereof and having a plurality of lower fingers, the opening defining a female die surface and the lower fingers being adapted to extend inwardly form the perimeter of the opening generally toward the center of the opening; placing a sheet of material having an upper surface and a lower surface between the male die and the female die with at least a portion of the sheet of material disposed over the opening of the female die; moving an upper ring having a plurality of upper fingers into a pleat-controlling position wherein each upper finger engages the upper surface of the sheet of material between two of the lower fingers; and moving the male die through the upper ring and into a forming position wherein the male die is disposed in the opening of the female die with a least a portion of the sheet of material being disposed generally between the male die surface and the female die surface; wherein each lower finger engages the lower surface of the sheet of material between two corresponding upper fingers, and cooperates with the two corresponding upper fingers to form a pleat in the sheet of material between the lower finger and each of the corresponding upper fingers as the male die and the female die form the sheet of material into a flower pot or flower pot cover.
Claim 2
Independent Claim 268 words
A method for forming a sheet of material into a flower pot or flower pot cover, the steps of the method comprising: providing a male die having a male die surface; providing a female die having an opening formed through a portion thereof and having a plurality of lower fingers, the opening defining a female die surface and the lower fingers being adapted to extend inwardly form the perimeter of the opening generally toward the center of the opening; placing a sheet of material having an upper surface and a lower surface between the male die and the female die with at least a portion of the sheet of material disposed over the opening of the female die; moving an upper ring having a plurality of upper fingers into a pleat-controlling position wherein each upper finger engages the upper surface of the sheet of material between two of the lower fingers; and moving the male die through the upper ring and into a forming position wherein the male die is disposed in the opening of the female die with a least a portion of the sheet of material being disposed generally between the male die surface and the female die surface; wherein each lower finger engages the lower surface of the sheet of material between two corresponding upper fingers, and cooperates with the two corresponding upper fingers to form a pleat in the sheet of material between the lower finger and each of the corresponding upper fingers as the male die and the female die form the sheet of material into a flower pot or flower pot cover.
Claim 3
Dependent Claim 33 words
The method of claim 1 wherein the sheet of material is constructed of a material selected from the group of materials consisting of cellophane, man-made organic polymer film, paper, fabric and combinations thereof.
Claim 4
Dependent Claim 34 words
The method of claim 1 further comprising the step of: adhesively sealing at least a portion of each pleat in the sheet of material between the male die surface and the female die surface.
Claim 5
Dependent Claim 34 words
The method of claim 1 further comprising the step of: heat sealing at least a portion of each pleat in the sheet of material between the male die surface and the female die surface.
Claim 6
Dependent Claim 43 words
The method of claim 1 further comprising the step of: providing a vacuum to releasably hold the sheet of material over the opening of the female die as the sheet of material is being formed into a flower pot or flower pot cover.
Claim 7
Dependent Claim 77 words
The method of claim 1 further comprising the step of: providing a sheet of material sized to extend beyond the male die surface when the male die and the female die are in the forming position wherein the male die surface and the female die surface form a lower base with closed pleats in the sheet of material and wherein the upper and lower fingers form an upper skirt with open pleats in the sheet of material
Claim 8
Independent Claim 260 words
A method for forming a sheet of material into a flower pot or flower pot cover, the steps of the method comprising: providing a male die having a male die surface; providing a female die having an opening formed through a portion thereof and having a plurality of lower fingers, the opening defining a female die surface and the lower fingers having a base member attached to the female die and a forming member extending angularly from the base member and inwardly from the perimeter of the opening, each forming member having an attached end and a opposite forming end; placing a sheet of material having an upper surface and a lower surface between the male die and the female die with at least a portion of the sheet of material disposed over the opening of the female die; moving an upper ring having a plurality of upper fingers into a pleat-controlling position wherein each upper finger engages the sheet of material and wraps a pleat in the sheet of material around the forming member of a corresponding one of the lower fingers, and the pleat extending form the attached end, around the forming end and back to the attached end of the forming member of the corresponding lower finger; and moving the male die through the upper ring and into a forming position wherein the male die is disposed in the opening of the female die with a least a portion of the sheet of material being disposed generally between the male die surface and the female die surface.
Claim 9
Independent Claim 260 words
A method for forming a sheet of material into a flower pot or flower pot cover, the steps of the method comprising: providing a male die having a male die surface; providing a female die having an opening formed through a portion thereof and having a plurality of lower fingers, the opening defining a female die surface and the lower fingers having a base member attached to the female die and a forming member extending angularly from the base member and inwardly from the perimeter of the opening, each forming member having an attached end and a opposite forming end; placing a sheet of material having an upper surface and a lower surface between the male die and the female die with at least a portion of the sheet of material disposed over the opening of the female die; moving an upper ring having a plurality of upper fingers into a pleat-controlling position wherein each upper finger engages the sheet of material and wraps a pleat in the sheet of material around the forming member of a corresponding one of the lower fingers, and the pleat extending form the attached end, around the forming end and back to the attached end of the forming member of the corresponding lower finger; and moving the male die through the upper ring and into a forming position wherein the male die is disposed in the opening of the female die with a least a portion of the sheet of material being disposed generally between the male die surface and the female die surface.
Claim 10
Dependent Claim 33 words
The method of claim 7 wherein the sheet of material is constructed of a material selected from the group of materials consisting of cellophane, man-made organic polymer film, paper, fabric and combinations thereof.
Claim 11
Dependent Claim 34 words
The method of claim 7 further comprising the step of: adhesively sealing at least a portion of each pleat in the sheet of material between the male die surface and the female die surface.
Claim 12
Dependent Claim 34 words
