Abstract

Abstract An integrally molded plant pot for growing a plant which has a base portion and a plurality of flap portions connected to the base portion, each having a plurality of perforated penetrating holes. The base portion is surrounded by the flap portions. The flap portions are assembled by means of a clamping portion provided on a side edge thereof. The flap portions are economically designed to be molded in an injection molding machine or the like, so that they can be opened outwardly at a bending portion provided at the bottom surface of the flap portions. The pot has a strength and a flexibility sufficient to make removal of the plant therefrom easy during transplantation from the pot.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 133 words
A pot for growing and transplanting plants comprising: an inner base portion having a plurality of holes therethrough; a plurality of flap portions adjacent each other flexibly connected to said inner base portion and having a plurality of holes therethrough, each flap portion comprised of: a flat outer base portion flexibly connected to said base portion and having a plurality of holes therethrough, and a side portion projecting upward from said flat outer base portion and having a plurality of holes therethrough, and said flexible connection permitting said flap portions to be flexed outwardly for transplanting; and clamping means on said flap portions for holding said flap portions together in a closed position for growing said plant, said inner and outer base portions being coplanar when said pot is in said closed position.
Claim 2
Dependent Claim 133 words
A pot for growing and transplanting plants comprising: an inner base portion having a plurality of holes therethrough; a plurality of flap portions adjacent each other flexibly connected to said inner base portion and having a plurality of holes therethrough, each flap portion comprised of: a flat outer base portion flexibly connected to said base portion and having a plurality of holes therethrough, and a side portion projecting upward from said flat outer base portion and having a plurality of holes therethrough, and said flexible connection permitting said flap portions to be flexed outwardly for transplanting; and clamping means on said flap portions for holding said flap portions together in a closed position for growing said plant, said inner and outer base portions being coplanar when said pot is in said closed position.
Claim 3
Dependent Claim 20 words
A pot as claimed in claim 1, wherein said side portion is integrally formed with said flat outer base portion.
Claim 4
Dependent Claim 83 words
A pot as claimed in claim 1, wherein the relationship between the solid surface area of said pot and the area of said holes through said pot is defined by the equation: (a)(n)/A × 100% ≧ 20% where: "A" is total inside area of said pot in mm 2 , "a" is the total are of each hole in mm 2 , and "n" is the total numbers of holes, and wherein the diameter of each hole is from 3 - 10 mm.
Claim 5
Dependent Claim 21 words
A pot as claimed in claim 1 wherein said holes through said side portions pass therethrough at an angle relative thereto.
Claim 6
Dependent Claim 34 words
A pot as claimed in claim 1, wherein said outer base portion is flexibly connected to said inner base portion by a continuous flexible U-shaped channel projecting upward toward the inside of said pot.
Claim 7
Dependent Claim 34 words
A pot as claimed in claim 1, wherein said outer base portion is flexibly connected to said inner base portion by a continuous flexible V-shaped channel projecting upward toward the inside of said pot.
Claim 8
Dependent Claim 34 words
A pot as claimed in claim 1 wherein said outer base portion is flexibly connected to said inner base portion by a discontinuous flexible U-shaped channel projecting upward toward the inside of said pot.
Claim 9
Dependent Claim 34 words
A pot as claimed in claim 1 wherein said outer base portion is flexibly connected to said inner base portion by a discontinuous flexible V-shaped channel projecting upward toward the inside of said pot.
Claim 10
Dependent Claim 48 words
A pot as claimed in claim 1 wherein said outer base portion and said inner base portion are integrally formed and said flexible connection between said portions is comprised of a series of perforations through the material integrally forming said outer base and side portions between said portions.
