DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention concerns a flower pot comprising a container portion, the lower part of which being adapted to receive a bottom insert which defines a bottom chamber for collecting water together with the bottom wall of said container part, said bottom chamber being provided with a liquid overflow, and said bottom insert constituting the upper limitation, and said bottom wall constituting the lower limitation of said chamber.
Said bottom chamber shall not only serve as a collecting means for surplus water, e.g. as a result of daily watering the plant, but shall also be able to receive a water supply which the plant can drain, so that it would be enough with watering fewer times.
BACKGROUND OF THE INVENTION
Known flower pots of said kind are formed in such a way that the filling of the flower pot, e.g. earth gets into contact with water collected in said bottom chamber at points distributed over the total area of the bottom. This can result in moistening the lowermost layer of said filling too much, so that said layer becomes sour.
SUMMARY OF THE INVENTION
It is the object of the invention to indicate a flower pot by means of which said disadvantage can be avoided.
The invention is characterized in, that said bottom insert comprises a sunk part extending downwardly into said bottom chamber past the niveau of said overflow, said sunk part at its lower end comprising a passage opening towards said chamber, and at its upper end being open for receiving filling, e.g. earth.
Filling filled into said sunk part may thus serve as a wick which sucks water up from said bottom chamber for distributing it to the remaining filling. The dimensions of said sunk part, and consequently the quantity of filling used for filling said sunk part can be limited so much that in practice there will be no danger for the filling becoming sour. Since it is not necessary to shape the remaining part of said bottom insert with respect to receive water from said bottom chamber, the bottom insert may be shaped in such a way that said remaining part will be positioned considerably higher than the niveau of said overflow. Thus, in said bottom chamber, a satisfactory large space can be maintained between the maximum liquid level and said bottom insert for maintaining a cushion of air.
According to the invention, said sunk part of said bottom insert may be shaped like a groove extending along the periphery of said bottom insert. Said groove embodiment may secure an adequate distribution of the water sucked up in the filling, and moreover contribute to a stiffening of said bottom insert.
According to the invention a limiting wall of said sunk part may provide a space together with the lowermost part of the wall of the container portion, said space being in open communication with said bottom chamber, and said space may be provided with overflow openings at its upper part, said openings being positioned higher than said overflow of said bottom chamber. This embodiment results in the specific advantage, that surplus water will be poured off in case said flower pot is tilting and the main overflow, which is normally positioned at the center area of the container part bottom, is not able to operate because of said tilting. A flower pot, which has been planted up, and the bottom chamber of which has been filled with water, may thus be emptied totally of water, e.g., when having to be transported after having been sold.
An embodiment considering all the features which are characteristic for the present invention, is characterized in that said sunk part of the bottom insert is shaped as a circumferential groove, which is adapted at its bottom to rest on said bottom wall by means of spacing elements, and which is surrounded by an outwardly extending flange at its top, which extends both towards the side wall of the container portion when said bottom insert is inserted into said container portion, and in a distance of height above an inwardly extending shoulder on said container side wall, the distance of height of said shoul
