Patent ID: 7690150

Claim:
Plant container comprising: a pot ( 1 ) and a coaster ( 20 ) made of plastic; wherein the coaster ( 2 ) is closed at the bottom and serves as a water dish detachably attached by coupling elements to the pot ( 1 ); wherein the pot is provided with holes on the bottom for drainage of water from the pot to the coaster; wherein the pot ( 1 ) has a dome ( 8 ) in the form of a truncated cone forming a guide surface ( 9 ) tapering in conical shape; wherein the guide surface of the pot is aligned rotationally symmetrical about a central axis of symmetry of the pot; wherein the coaster ( 2 ) has a dome ( 14 ) in the form of a truncated cone forming a guide surface ( 16 ) tapering in conical shape; wherein the guide surface of the coaster is aligned rotationally symmetrical about a central axis of symmetry of the coaster; wherein the guide surface of the coaster is engaged with the guide surface of the pot so that the central axis of symmetry of the coaster is both aligned and parallel with the central axis of symmetry of the pot and the coaster is rotatable relative to the pot about the central axis of symmetry of the pot; wherein the coupling elements ( 11 , 15 ) include a plurality of openings spaced about the central axis of symmetry of the pot and a plurality of hooks cooperating with the openings to form a bayonet coupling; and wherein the bayonet coupling is adapted so that each of the hooks are axially inserted and withdrawn from a first portion of the openings without deformation of the openings or the hooks and rotated about the central axis of symmetry of the pot from the first portion of the openings to a second portion of the openings from which the hooks cannot be axially withdrawn from the openings to couple the coaster and the pot against relative axial movement therebetween; wherein the domes are provided with the coupling elements.
