Abstract

A container of the kind used for supplying water and/or nutrients directly into the soil adjacent the plant comprises a bottle for holding the supply of water and a cap structure which encloses one end of the bottle. The cap structure is effective to both support the bottle upright on the soil adjacent the plant and to transfer liquid downwardly from the bottle into the soil. The cap structure includes a spike which extends from an outer, flat surface of the cap so that the spike structure can be inserted into the soil until the outer, flat surface of the cap is engaged with the upper surface of the soil. The spike and the flat surface of the cap thus hold the bottle in a stable, upright position. A wick extends through an opening in the cap. The wick has an inner end immersed in the liquid within the bottle and has an outer end which is inserted into the soil. The inner and outer ends of the wick are preferably cut to a tapered figuration for opening the pore structure of the wick and for permitting, at the outer end of the wick, a controlled transfer of fluid from the wick to the soil by capillary action.

Claims

1. A container of the kind used for supplying water and/or nutrients directly into the soil adjacent a plant, said container comprising,

bottle means for holding a supply of fluid to be applied into the soil adjacent a plant,

bottle support and liquid applicator means for both supporting the bottle upright on the soil adjacent a plant and for also transferring liquid downwardly from the bottle into the soil,

said bottle support and liquid applicator means comprising,

a cap which encloses one end of the bottle,

a single spike formed integral with and extending from the cap and insertable into the soil for supporting the bottle upright with the cap facing the soil, said spike having a rounded outer end and a tapered elongated shape for minimizing any possible damage to the root structure of the plant,

said cap having an opening in the cap adjacent the spike means,

wick means extending through said opening and having an inner end immersed in the liquid within the bottle and having an outer end insertable into the soil for transmitting fluid downwardly from the bottle into the soil at a rate which maintains sufficient moisture in the soil to keep the plant in a well cared for condition, said wick means being formed of a polyester fiber bar material which is stiff enough to permit the part of the wick means which extends outside of the cap to be pushed into the soil, said wick means having a porosity of a size which facilitates wicking of the fluid into the soil, and said outer end of the wick means being substantially shorter in length than the length of the spike so that the spike, rather than the wick means, provides the support for holding the bottle upright on the soil.

2. The invention defined in claim 1 wherein the wick means have a cut, tapered outer end for facilitating entry into the soil and for opening the pore structure of the tapered outer end, and wherein the side walls of the wick means extending upwardly from the tapered end have pores which are substantially closed off by a heat treatment step used in the course of manufacture of the wick means so that the fluid flows substantially only through the cut, tapered outer end and not through the side walls.

3. The invention defined in claim 1 wherein the wick means are generally square shaped in cross section with each side having a width between 1/8 inch and 3/16 inch.

4. The invention defined in claim 1 wherein the cap can be adjustably tightened against the bottle to regulate the amount of air which can enter the bottle at the juncture of the cap and the bottle so that the air pressure within the bottle can be regulated as liquid flows out of the bottle through the wick means to thereby exert a control on the rate at which fluid is transferred from the bottle to the soil.

5. The invention defined in claim 1 wherein the bottle has markings on the side to provide a measure of the amount of fluid which has been transferred from the bottle to the soil.
