Patent ID: 7204056

Claim:
A stackable deep-drawn plastic plant pot comprising: an at least slightly conical wall ( 3 ) and a bottom ( 5 ) connected to the conical wall ( 3 ); wherein the conical wall ( 3 ) has a rim area ( 2 ) remote from the bottom ( 5 ); wherein the rim area ( 2 ) is comprised of an upward-facing first ledge ( 7 ) and a downward-facing second ledge ( 8 ), located below the first ledge ( 7 ); wherein the rim area ( 2 ) comprises an intermediate support area ( 9 ) having a first end connected to the first ledge ( 7 ) and a second end connected to the second ledge ( 8 ); wherein a stacking spacing of the deep-drawn plastic plant pot, when stacked in a stack, is determined by the first and second ledges ( 7 , 8 ); wherein the first and second ledges ( 7 , 8 ), in a plan view onto the rim area ( 2 ), at least partially overlap; wherein the intermediate support area ( 9 ) has a wave shape at least at one of the first and second ends which softens a cross-sectional stiffness of the rim area to permit deformation of the rim area for improved removal from a deep drawing mold; wherein divisions having a width defined by the wave shape are not significantly greater than a height of the intermediate support area so that deformations of the rim area during removal from the deep drawing mold are introduced over the width of each of the divisions and with minimal deformations into the residual shape of the plastic plant pot; wherein the second ledge ( 8 ) has a contour matching the wave shape of the intermediate support area ( 9 ) and overlaps in a plan view radially at least most of a radial width of the first ledge ( 7 ); wherein the second ledge ( 8 ) continuously extends uninterrupted over an entire periphery of the plant pot; wherein the first ledge ( 7 ) forms an upper flange rim ( 12 ) of the rim area ( 2 ); wherein the upper flange rim ( 12 ) has a wall thickness that is greater than a wall thickness of the remaining parts of the plastic plant pot; and wherein an inner edge of the first ledge is larger in the radial direction than an inner edge of the second ledge; wherein the inner edge of the first ledge and the inner edge of the second ledge are sized to form an annular play of 0.1 mm therebetween when stacked in a stack.
