Abstract

A lockable vegetation pot and saucer is disclosed comprising a plastic pot having a pot base and integral pot sides diverging from the pot base. The pot has a plurality of pot stops extending from the inside surface of the pot sides. The angle of the diverging pot sides enables stacking of the pot with similar pots when the pot base engages the pot stops of an adjacent similar pot. A plurality of locking apertures are located in the pot sides each aperture having a locking side adjacent the pot base. The invention includes a plastic saucer having a saucer base and integral saucer sides diverging from the saucer base. The saucer has a plurality of saucer stops extending from the inside surface of the saucer. The angle of the diverging saucer sides enables stacking of the saucer with similar saucers when the saucer base engages the saucer stops of an adjacent similar saucer. The saucer includes a plurality of tabs extending inwardly from the inside surface of the saucer with each tab having a ramp surface and a locking surface whereby the ramp surfaces cause progressive deformation of the saucer upon insertion of the pot into the saucer until the locking surfaces of the tabs engage the locking sides of the locking apertures and thereby resiliently hold the pot against the saucer base.

Description of the Preferred Embodiment

FIGS. 1, 1A and 2 show a plastic vegetation pot 15 having a base 16 and integral sides 17 which diverge from the pot base 16. The base 16 includes a plurality of drain apertures 19 uniformly distributed in the pot base 16. Although the pot has been shown to be circular in FIGS. 1 and 2, the terms pot and saucer contemplate vegetation containers having various cross-sections including polygons, ellipses and the like.

A minor portion 17A of the pot sides 17 has an increased cross-sectional area extending to the top 21 of the pot sides 17 with a pot shoulder 22 extending between the minor portion 17A and a major portion 17B of the pot side 17. A pot rim 24 extends around the top 21 of the pot sides 17 and has an increased wall thickness to provide added strength at the top of the pot 15. A second rim 25 having an increased wall thickness extends about an inner surface of the pot sides 17 to add additional strength to the pot 15. A plurality of pot legs 27 are uniformly distributed about the pot base 16 and extend downwardly from a bottom surface 30 of the pot base 16 at a spaced distance 28 from the outer perimeter 29 of the pot base 16. A plurality of pot stops 31 are uniformly distributed about the pot base 16 and extend from the inside surface of the pot sides 17 a distance 33 which is less than the spaced distance 28 between the pot legs 27 and the outer perimeter 29 of the pot base 16. A plurality of retangular locking apertures 36 are uniformly distributed about the pot sides 17 with each locking aperture having a locking side 36A which is adjacent the pot base 16. The plurality of locking apertures 36 are respectively adjacent the plurality of pot legs 27.

FIGS. 3 and 3A show two similar stacked pots 15A and 15B to enable shipment of a plurality of pots in a small space. The angle of the diverging pot sides enables stacking of the pot 15A with the similar pot 15B with the pot base 16A of pot 15A engaging the pot stop 31B of pot 15B. The spaced distance 28A between the pot leg 27A and the outer perimeter 29A of pot 15A is greater than the distance 33B of the pot stop 31B from the pot side. Consequently, the pot stop 31B engages only the base 16A of the pot 15A and the pot stop 31B cannot engage the pot leg 27A of the pot 15A. The pots 15A and 15B are stacked with the shoulder 22A being separated from the shoulder 22B. The pot stops 31 have the function of longitudinally separating pots so that they do not become wedged together due to the conical or diverging sides. Without such stops a stack of pots could become so wedged together as to be difficult to separate or even may cause splitting of the bottom pot.

FIGS. 4, 5, and 6 are respectively top, side, and bottom views of a plastic saucer 45 having a saucer base 46 and integral saucer sides 47 diverging from the saucer base 46. A major portion 47A of the saucer sides 47 has an increased cross-sectional area extending to the top 51 of the saucer sides 47 with a saucer shoulder 52 extending between the major portion 47A and a minor portion 47B. A saucer rim 54 extends around the top 51 of the saucer sides 47 and has an increased wall thickness to add strength to the saucer sides 47. A plurality of saucer legs 57 extend from a bottom surface 56 of the saucer base 46 at a spaced distance 58 from the outer perimeter 59 of the saucer base 46. The saucer legs 57 are uniformly distributed about the saucer base 46. A plurality of saucer stops 61 extend from an inside surface of the saucer sides 47 at the saucer shoulder 52 a distance 63 which is less than the spaced distance 58 of the saucer legs 57. FIGS. 4 and 5 show a plurality of tabs 66 extending inwardly from the inside surface of the saucer wall 47 having a length parallel to the saucer base 46 commensurate with the length of the locking sides 36A of the rectangular apertures 36. The tabs 66 extend inwardly from the inside surface of the saucer wall 47 and from detents 71 on the outside surface of the saucer wall 47. The tabs 66 are disposed adjacent to the saucer legs 57 as shown in FIG. 6.

FIG. 7 is an enlarged sectional view of a portion of the saucer sides 47 showing the increased wall thickness of the saucer rim 54 extending to the top 51 of the saucer sides 47.

FIG. 8 shows two similar saucers 45A and 45B being stacked to enable shipment of a plurality of saucers in a small space. The angle of the diverging saucer sides enables stacking of saucer 45A within similar saucer 45B with the saucer shoulder 52A engaging the saucer stops 61B of saucer 45B. The distance 63B of the saucer stop 61B of pot 45B is less than the length of the saucer shoulder between the major and the minor portions of the saucer sides. Consequently the saucer stops 61B engage only the saucer shoulder 52A. The stacked position of the saucers 45A and 45B is similar to the stacked position of the pots 15A and 15B shown in FIG. 3, and again the stops 61 prevent wedging together or splitting of the stacked saucers. The stacked saucers 45A and 45B shown in FIG. 8 may be stacked within the stacked pots 15A and 15B shown in FIG. 3 for shipping stacked saucers with stacked pots to save additional shipping space. The angle of the diverging saucer sides 47. is substantially equal to the angle of the diverging pot sides 17 to enable the aforementioned cooperation.

FIG. 9 is an expanded sectional view of a portion of the saucer in FIG. 5 showing in greater detail the tab 66 having a ramp surface 68 and a locking surface 69. The ramp surface 68 extends upwardly and outwardly relative to the saucer base 46 whereas the locking surface 69 extends downwardly and outwardly at a greater angle than the ramp surface 68. The tabs 66 are pressed or formed in the minor sides 47B as shown by the detents 71. In one embodiment of the invention as actually constructed, angles of about 25.degree. and 45.degree. to the longitudinal axis were found satisfactory for the ramp and locking surfaces 68 and 69, respectively.

FIG. 10 is a side view of the interlocking pot 15 and saucer 45 mounted in the upright position with the saucer legs 57 supporting the structure.

FIG. 11 is a sectional view of the interlocking pot 15 and saucer 45 assembly shown in FIG. 10. The pot base 16 is spaced from the saucer base 46 by the pot legs 27 to allow drainage to the saucer 45 through the drain holes 19 and apertures 36 enabling irrigation thereby. When the pot 15 is inserted into the saucer 45 the ramp surfaces 66 cause a progressive deformation of the saucer sides 47 until the locking surfaces 69 of the tabs 66 engage the locking sides 36A of the locking apertures 36. The saucer substantially returns to the original shape while resiliently holding pot legs 27 against the top surface of the saucer base 46. The engagement between the locking surfaces 69 and the locking side 36A of the locking aperture 36A is more fully shown in FIG. 12.

FIG. 12 is a magnified view of the engagement between the locking surface 69 and the locking side 36A which resiliently urges the pot legs 27 towards the top surface of the saucer base 46. The locking side 36A includes a portion of the pot base 16 since the locking aperture 36 extends substantially to the pot base 16.

The invention has been described as a vegetation pot and saucer which may either have cross-section that may be circular, a polygon, or the like comprising in combination; a pot 15 having a pot base 16. A plurality of locking apertures 36 are located in the pot sides 17 adjacent the pot base 16. A saucer 45 has a saucer base 46 and integral saucer sides 47 extending from the saucer base 46 for engagement with the pot 15. The invention includes a plurality of tabs 66 extending from an inside surface of the saucer 45 for engaging the plurality of locking apertures 36 to interlock the saucer and the pot.

The present disclosure includes that contained in the appended claims, as well as that of the foregoing description. Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
