Abstract

Apparatus for automatically watering one or more plants growing in an container such as a growbag 1 comprises a water reservoir 3 formed from plastics film, support means 7 in the form of a lattice framework for supporting the growbag, and at least one spike 8 bearing a moisture absorbing wick 9. In use, the spike 8 pierces the growbag and introduces the wick into the soil, the ends of the wick being in water in the reservoir, so that water is gradually transferred to the soil from the reservoir. <IMAGE>

Description

AUTOMATIC WATERING APPARATUS The present invention relates to apparatus for automatically watering a plant or plants within a container, and particularly to apparatus of this type incorporating a moisture-absorbing wick.

According to the present invention there is provided apparatus for automatically watering one or more plants growing in a container, the apparatus comprising a reservoir for holding water, means located within said reservoir for supporting the container from beneath, and at least one spike adapted for insertion into the soil surrounding the plant or plants, the or each spike also being adapted to hold a moisture-absorbing wick in contact with the soil whereby water contained in the reservoir is, in use, gradually transferred from the reservoir, along the wick, into the soil.

The type of container to which the present invention is particularly suited is a container of flexible, plastics material, commonly referred to as a growbag.

When used with a container of this type, the spike pierces the growbag from underneath, thus introducing the wick into the soil.

Any number of spikes and/or wicks may be provided, depending on the type and number of plants in the container.

The spike or spikes are preferably formed integrally with the means for supporting the container.

The reservoir may be formed from heavy duty flexible plastics film which is folded or welded at the corners to form a tray. The edges of the film which is preferably of rectangular shape or folded over onto the top of the container and may conveniently be secured there by adhesive tape or the like.

The means for supporting the container in this case preferably comprises a lattice framework of plastic injection moulded strips, slotted together and located in the bottom of the tray. There may be several of these frameworks, typically three, to support the container along its length.

The reservoir preferably includes means to allow water to be introduced into the reservoir even when the growbag is in position. This may be achieved by forming one or more of the upper corners of the tray into a funnel shape.

Alternatively, the reservoir may be constructed from ridgid, vacuum formed plastic sheets, and in this case the means for supporting the container preferably comprises ribbing formed integrally with the tray, and extending upwardly from the bottom of the tray.

The wick is preferably able to absorb moisture readily, and is also preferably resistant to rotting.

The spike is preferably slotted at its upper most end, the centre of the wick being inserted in this slot, so that each end of the wick is immersed in the water.

An embodiment of the present invention will now be described by way of example only with reference to the accompanying drawings in which: Figure 1 is a perspective view of plant watering apparatus of the present invention being used with a growbag; Figure 2 is a perspective view showing the growbag being lowered onto the support means; Figure 3 is a close up view of a spike and wick forming part of the apparatus of the present invention; Figure 4 is a sectional view through the growbag and the apparatus showing its mode of operation; Figure 5 is a plan view of one of the strips forming the lattice framework;- Figure 6 is a side elevation of the strip shown in Figure 5; Figure 7 is a section on line A-A of Figure 5; Figure 8 is a section on line B-B of Figure 5.

Referring to the drawings, apparatus for automatically watering a container 1, such as a growbag, containing one or more plants 2, comprises a reservoir 3 for holding water 4. The reservoir 3 may be constructed from heavy duty flexible plastics film, folded or welded at the corners to form the shape of a tray. The edges 5,6 of the film are folded over the top of the growbag 1 and secured to the growbag by strips of adhesive tape 5a,6a. One or more of the upper corners of the tray may be formed into a funnel shape so that water may be poured through the funnel to top up the reservoir level, even when the growbag is in place on top of the reservoir.

A lattice framework of four plastic injection moulded strips 7 slotted together and located in the bottom of the tray acts as a support for the growbag 1, raising the growbag above the level of the water.

A spike 8 is integrally formed with two of the strips and is slotted at its upper end to receive the centre portion of a wick 9, the ends of which are immersed in the water.

In use, when the growbag 1 is placed on top of the lattice framework, the spike 8 pierces the plastics film of the growbag, thus introducing the wick 9 into the soil.

In use, the arrangement is such that water is transferred along the wick from the reservoir into the soil, thus enabling the container 1 and the growing plants contained therein to be left for long periods of time without attention.

Figures 6, 7 and 8 show the lattice framework in more detail. Each lattice framework, of which three are shown in Figure 2, comprises four strips 7. Two of the four strips include an integrally formed spike 8 and two are as shown in Figure 5 but wiht the spike omitted. Each strip 7 includes two slots 7a, 7b which slots serve to receive an adjacent strip and secure the strips at 900 to each other, as shown in Figure 2. Thus, each framework bears two spikes 8 and two associated wicks 9.

The reservoir 3 may alternatively be constructed from ridged, vacuum formed plastic sheet, with integral ribbing extending upwardly from the bottom of the tray to form the support for the growbag 1.

Claims
