Description
PLANT CONTAINER WITH BUILT-IN WATER RESERVOIR
The invention relates to a plant container, more particularly to a plant container with a built-in water reservoir.
A conventional plant container for growing plants is shown in Figure 1. A main drawback arising from the use of the conventional plant container is that the plant owner usually forgets to provide water thereto regularly, thereby resulting in the death of the plants grown therein.
The objective of the present invention is to provide a plant container which can be used indoors or outdoors and which has a built-in water reservoir, thereby preventing the death of the plants grown in the plant container due to infrequent watering of the latter.
Another objective of the present invention is to provide a plant container with a water flow regulator for controlling the flow of water from the built-in water reservoir to soil in the plant container.
Still another objective of the present invention is to provide a plant container which can be divided into several regions with different water requirements.
A further objective of the present invention is to provide a plant container which can be used with a water supplying device to further reduce the frequency of watering of the plant container.
Accordingly, the plant container of the present invention includes an outer receptacle and an inner receptacle which is smaller than the outer receptacle and which is provided in the outer receptacle. The inner receptacle is used to grow plants therein. The inner and outer receptacles confine a water reservoir therebetween for receiving water therein. The inner receptacle has a surrounding wall that is formed with at least one water inlet hole to permit water in the water reservoir to flow into the inner receptacle.
In one embodiment, the plant container is provided with a water flow regulator that extends between the inner and outer receptacles and that is used to control the water flow through the water inlet hole.
In another embodiment, the plant container is provided with a water supplying device that is connected to the outer receptacle for supplying water to the water reservoir.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments, with reference to the accompanying drawings, of which:
Figure 1 is a sectional view of a conventional plant container;
Figure 2A is a sectional view of the first preferred embodiment of a plant container according to the present invention;

Figure 3A is a fragmentary sectional view illustrating a water flow regulator of the third preferred embodiment of a plant container according to the present invention;
Figure 3B is a fragmentary sectional view illustrating a water flow regulator of the fourth preferred embodiment of a plant container according to the present invention;;
Figure 4 is an exploded perspective view of the fifth preferred embodiment of a plant container according to the present invention;
Figure 5 is a partly sectional view illustrating a water supplying device of the sixth preferred embodiment of a plant container according to the present invention; and
Figure 6 is a partly sectional view illustrating an automatic water flow regulator of the seventh preferred embodiment of a plant container according to the present invention.
Before the present invention is described in greater detail, it should be noted that like elements are indicated by the same reference numerals throughout the disclosure.
Referring to Figure 2A, the first preferred embodiment of a plant container according to the present invention is shown to comprise inner and outer receptacles 10, 20. In this embodiment, the inner and outer receptacles 10, 20 are generally cylindrical pots. The inner receptacle 10 is used to grow plants therein and has a surrounding wall which is formed with at least one appropriately-sized water inlet hole 11.
The inner receptacle 10 has a diameter which is smaller than that of the outer receptacle 20 and is provided inside the latter. The inner and outer receptacles 10, 20 confine an annular water reservoir 15 therebetween.
The water reservoir 15 is filled with water or liquid plant food that flows into the inner receptacle 10 via the water inlet hole 11. The presence of the water reservoir 15 permits infrequent watering of the plant container. A cover member 16 may be detachably or fixedly mounted on top ends of the inner and outer receptacles 10, 20 to cover the water reservoir 15, thereby minimizing the loss of liquid in the water reservoir 15 due to evaporation.
Figure 2B illustrates the second preferred embodiment of a plant container according to the present invention. The second preferred embodiment is substantially similar to the first preferred embodiment except that the inner and outer receptacles 10, 20 are formed integrally.
Figure 3A is a fragmentary sectional view of the third preferred embodiment of a plant container according to the present invention. The plant container further comprises a water flow regulator 30 for controlling the flow of water into the inner receptacle 10 via the water inlet hole 11. In this embodiment, the water flow regulator 30 extends between the inner and outer receptacles 10, 20 and includes an internally threaded tubular valve seat 32 and a threaded valve member 31 which engages threadably the tubular valve seat 32. The outer receptacle 20 is formed with a radial opening that is aligned with the water- inlet hole 11. The tubular valve seat 32 extends from the outer receptacle 20 at the radial opening in a radial inward direction.The distal end of the tubular valve seat 32 is spaced from the surrounding wall of the inner receptacle 10 so as to confine a water channel 33 therebetween. The threaded valve member 31 has a head portion which is formed with a screw slit 34 that is accessible via the radial opening in the outer receptacle 20. The threaded valve member 31 further has a distal tapered end 311 that extends into the water channel 33. The tip of a tool (not shown) is inserted into the screw slit 34, and the tool is operated to rotate the threaded valve member 31, thereby varying the degree of extension of the distal tapered end 311 of the threaded valve member 31 into the water inlet hole 11 to control the flow of water into the inner receptacle 10. A sealing ring 35 is provided on the threaded valve member 31 adjacent to the head portion of the latter.The sealing ring 35 prevents the leakage of water from the water reservoir via the radial opening in the outer receptacle 20.
Figure 3B is a fragmentary sectional view of the fourth preferred embodiment of a plant container according to the present invention. The plant container of this embodiment also comprises a water flow regulator 30' for controlling the flow of water into the inner receptacle 10 via the water inlet hole 11.
The construction of the water flow regulator 30' is substantially similar to that of the previous embodiment except that the distal end of the threaded valve member 31' is flat and is provided with a layer of water absorbent sponge 36 that presses against the surrounding wall of the inner receptacle 10. When a tool is operated so as to rotate the threaded valve member 31' and move the latter relative to the inner receptacle 10, the degree of compression of the water absorbent sponge 36 is varied to vary correspondingly the rate of water flow into the inner receptacle 10.
Note that the inner and outer receptacles 10, 20 are preferably made of a transparent material in order to enhance the appearance of the plant container and to facilitate viewing of the position of the threaded valve member 31, 31' relative to the inner receptacle 10.
Figure 4 illustrates the fifth preferred embodiment of a plant container according to the present invention. The plant container of this embodiment includes a generally rectangular outer receptacle 531 and a generally rectangular inner receptacle 50 formed integrally with the outer receptacle 531. As with the previous embodiments, the inner receptacle 50 is used to grow plants therein and has a surrounding wall which is formed with at least one water inlet hole 501. The lengths of the inner and outer receptacle 50, 531 are equal. However, the width of the inner receptacle 50 is smaller than that of the outer receptacle 531, thus forming water reservoirs 54 on two sides of the inner receptacle 50. The inner receptacle 50 has a bottom which is formed with a longitudinal upward partition 51 that divides the interior of the inner receptacle 50 into two regions.The plant container further comprises a partition plate 52 which has a bottom edge that is formed with a slit 520 for engaging the partition 51.
The partition plate 52 serves to further divide the interior of the inner receptacle 50 into additional regions. The bottom of the plant container is formed with a longitudinal groove 53 to facilitate mounting of the plant container on an inverted T-shaped plantsupporting platform 55.
Note that the partition plate 52 may be formed integrally with the inner receptacle 50. The partition plate 52 is further formed with at least one appropriately-sized water inlet hole 521. The location, distribution and size of the water inlet hole 521 may correspond with the water requirement for the particular region in the inner receptacle 50.
Figure 5 is a partly sectional view illustrating a water supplying device of the sixth preferred embodiment of a plant container according to the present invention. The water supplying device includes a tubular connector 60 which confines an axial passage 61. The tubular connector 60 is mounted to a bottom portion of the outer receptacle 20 and is connected to one end of a water pipe 70. The other end of the water pipe 70 is connected to a water container 80. The tubular connector 60 and the water pipe 70 serve to communicate the water reservoir of the plant pot and the interior of the water container 80.
The tubular connector 60 has an inner wall surface which is formed with an annular groove 62. A valve piece 63 is disposed in the axial passage 61 and has a periphery which extends into the annular groove 62. The valve piece 63 has a diameter which is larger than that of the axial passage 61 but smaller than that of the annular groove 62.
Initially, the water levels in the water reservoir and in the water container 80 are kept approximately equal to prevent the valve piece 63 from blocking the axial passage 61. As the water level in the water reservoir drops, water flows from the water container 80 into the water reservoir via a gap that is formed between the periphery of the valve piece 63 and the wall surface that confines the annular groove 62.
Because the combined water-receiving capacity of the water reservoir and the water container 80 is larger than that of the previous embodiments, the need for frequent watering of the plant container is minimized further.
Figure 6 is a fragmentary sectional view of the seventh preferred embodiment of a plant container according to the present invention. The plant container further comprises an automatic water flow regulator 70 for controlling the flow of water into the inner receptacle 10 via the water inlet hole 11. The water flow regulator 70 includes upper and lower housing parts 71, 72. The upper housing part 71 has an upper portion which is formed with a moisture inlet 711, and an externally threaded open lower portion 712. A water guiding member 73 and a swellable member 74 are disposed inside the upper housing part 71. The water guiding member 73 is disposed on top of the swellable member 74 and is adjacent to the moisture inlet 711.
The water guiding member 73 is made of a material, such as sponge, which can guide water entering the moisture inlet 711 to the swellable member 74. The swellable member 74 is made of a liquid expansible material which expands upon absorbing some water. The lower housing part 72 has an internally threaded upper portion 721 which engages threadedly the lower portion 712 of the upper housing part 71. The lower housing part 72 is formed with a radial water inlet 722 and has a bottom which is formed with a water outlet 723. An elongated valve member 75 is disposed axially inside the lower housing part 72 and has a distal tapered end 752 and a head portion which is connected to a resilient member 751. The swellable member 74 is disposed on top of the resilient member 751. The resilient member 751 serves to pull the valve member 75 away from the water outlet 723.The water flow regulator 70 further includes a retaining unit 76 which is connected to an inner wall surface of the surrounding wall of the inner receptacle 10. The retaining unit 76 serves to retain the lower housing part 72 on the inner receptacle 10 such that the water inlet 722 of the lower housing part 72 is aligned with the inlet hole 11 of the inner receptacle 10. The retaining unit 76 has a bottom which is formed with an outlet 761.
Initially, the swellable member 74 is dry and does not apply a pushing force on the valve member 75. Soil inside the inner receptacle 10 becomes moist due to the flow of water from the water reservoir 15 through the inlet hole 11 of the inner receptacle 10, the water inlet 722 and the water outlet 723 of the lower housing part 72, and the outlet 761 of the retaining unit 76.
When the soil in the inner receptacle becomes excessively moist, water enters into the upper housing part 71 via the moisture inlet 711. The water guiding member 73 guides the water which enters into the moisture inlet 711 to the swellable member 74, thereby causing the latter to expand and urge the distal tapered end 752 of the valve member 75 to close the water outlet 723 against action of the resilient member 751.
