     DETAILED DESCRIPTION 
     As illustrated in FIGS. 1 and 2, a collapsible receptacle assembly 10 for providing a children&#39;s ice skating rink comprises a first box member 12 having a major wall or base component 14 and three sidewall components 16, 18 and 20. Base 14 and sidewalls 16, 18 and 20 are all rectangular, the sidewalls being only several inches high. Sidewalls 16, 18 and 20 are joined to one another along their vertically extending, lateral edges to form a substantially C-shaped composite sidewall 21. 
     A second box member 22 has a major wall or base component 24 and three sidewall components 26, 28 and 30. Base 24 and sidewalls 26, 28 and 30 are all rectangular and the sidewalls are approximately the same height as sidewalls 16, 18 and 20. Sidewalls 26, 28 and 30 are joined to one another along their vertically extending, lateral edges to form a substantially C-shaped composite sidewall 31. 
     Box members 12 and 24 are characterizable as having open faces opposite major walls 14 and 24, respectively, and as having open sides opposite sidewall components 18 and 28, respectively. 
     Receptacle assembly 10 also comprises an additional, U-shaped member 32 having a major wall or base plate 34 and a pair of upstanding sidewall components 36 and 38 attached to opposite edges of base plate 34. 
     U-shaped member 32 is slightly larger than box member 12 and slightly smaller than box member 22. More specifically, the lengths of base components or plates 14, 34 and 24, i.e., the distances between sidewalls 16 and 20, sidewalls 26 and 30 and sidewalls 36 and 38, increase from one to the other, so that box member 12 is nestable within member 32 which in turn is nestable in box member 22, as shown in FIG. 2. 
     As shown in FIG. 1, base 14 and sidewalls 16 and 20 are provided along their outer surfaces with cross-sectionally T-shaped elongate grooves 42 for receiving cross-sectionally T-shaped lugs (not shown in FIG. 1) on the inner surfaces of base plate 34 and sidewalls 36 and 38, whereby box member 12 is slidably connectable to and insertable into U-shaped member 32. Similarly, U-shaped member 32 is provided on the outer surfaces of base 34 and sidewalls 36 and 38 with cross-sectionally T-shaped grooves 44 mating with T-shaped projections (see FIG. 4) on the inner surfaces of base 24 and sidewalls 26 and 30, whereby U-shaped member 32 is slidably connected to box member 22. 
     As illustrated in FIGS. 3 and 4, a lateral sidewall 46 of one receptacle assembly member may be provided on an outer surface with a multiplicity of T-shaped grooves 48 each receiving a respective T-shaped lug 50 which projects inwardly from a sidewall 52 of another receptacle assembly member. In addition, where receptacle assembly 10 is used as a children&#39;s ice skating rink or as an above-ground swimming pool (the sidewalls are of course higher in that application), either the outer surface of sidewall 46 or the inner surface of sidewall 52 is provided with an elongate sealing rib 54 preferably made of a resilient material different from the essentially rigid material of box members 12 and 22 and U-shaped member 32. However, rib 54 may be of the same material as the box member or U-shaped member of which it forms a component part. 
     As shown in FIG. 5, a resilient sealing rib 56 extends along both the base 58 and the two opposing sidewalls 60 of the respective receptacle assembly member 62. 
     As depicted in FIG. 6, a substantially impermeable sheet or web 64 of flexible synthetic resin material may be disposed in receptacle assembly 10 upon the sliding of members 12, 22 and 32 into an opened configuration. The sheet serves as a liner performing an added sealing function. 
     In the case that the receptacle assembly is being used as a swimming pool or ice skating installation, the opened receptacle assembly is filled with water 66. In the case of the skating rink, the water is further permitted to freeze. 
     As shown in FIGS. 7-9, another receptacle assembly 70 comprises four box-like members 72, 74, 78 and 80 each including a major wall or base portion 72a, 74a, 76a and 78a, as well as two contiguous sidewalls 72b and 72c, 74b and 74c, 76b and 76c, 78b and 78c. Member 72 is provided in an outer surface of base 72a and an outer surface of sidewall 72b with a plurality of elongate, cross-sectionally T-shaped grooves 72d slidably receiving respective cross-sectionally T-shaped projections (not shown) on the inner surfaces of base 74a and sidewall 74b, whereby member 74 slidably receives member 72 in a nesting configuration. Member 74 in turn is provided on the outer surfaces of base 74a and sidewall 74c with a plurality of elongate, cross-sectionally T-shaped grooves 74d slidably receiving respective cross-sectionally T-shaped projections (not shown) on the inner surfaces of base 76a and sidewall 76b, whereby member 76 slidably receives member 74 in a nesting configuration. 
     Member 72 is also provided in an outer surface of base 72a and an outer surface of sidewall 72c with a plurality of elongate, cross-sectionally T-shaped grooves 72e slidably receiving respective cross-sectionally T-shaped projections (not shown) on the inner surfaces of base 78a and sidewall 78b, whereby member 78 slidably receives member 72 in a nesting configuration. Member 78 in turn is provided on the outer surfaces of base 78a and sidewall 78c with a plurality of elongate, cross-sectionally T-shaped grooves 78d slidably receiving respective cross-sectionally T-shaped projections (not shown) on the inner surfaces of base 76a and sidewall 76b, whereby member 76 slidably receives member 78 in a nesting configuration. 
     In the completely closed or collapsed configuration of receptacle assembly 70, member 72 is nested within member 74 which in turn is nested within member 78 in turn nested within member 76. 
     Another collapsible container or receptacle assembly 110 is shown in an exploded, a collapsed and an opened configuration in FIGS. 10, 11 and 12, respectively. Various details of FIGS. 10-12 have been enlarged for purposes of illustration. 
     As illustrated in those drawing figures, receptacle assembly 110 comprises a first box member 112 having a major Wall or base component 114 and three sidewall components 116, 118 and 120. Base 114 and sidewalls 116, 118 and 120 are all substantially rectangular, sidewalls 116, 118 and 120 being joined together along their vertically extending, lateral edges to form a substantially C-shaped composite sidewall 121. 
     A second box member 122 has a major wall or base component 124 and three sidewall components 126, 128 and 130. Base 124 and sidewalls 126, 128 and 130 are all essentially rectangular and the sidewalls are approximately the same height as sidewalls 116, 118 and 120. Sidewalls 126, 128 and 130 are joined to one another along their vertically extending, lateral edges to form a substantially C-shaped composite sidewall 131. 
     Box members 112 and 124 are characterizable as having open faces opposite major walls 114 and 124, respectively, and as having open sides opposite sidewall components 118 and 128, respectively. 
     Receptacle assembly 110 also comprises an additional, U-shaped member 132 having a major wall or base plate 134 and a pair of upstanding sidewall components 136 and 138 attached to opposite edges of base plate 134. 
     U-shaped member 132 is slightly larger than box member 112 and slightly smaller than box member 122. More specifically, the lengths of base components or plates 114, 134 and 124, i.e., the distances between sidewalls 116 and 120, sidewalls 126 and 130 and sidewalls 136 and 138, increase from one to the other, so that box member 112 is nestable within member 132 which in turn is nestable in box member 122, as shown in FIG. 2. 
     Sidewalls 116 and 120 are provided along their free vertical edges with outwardly turned lips 140 and 142 forming respective vertically extending grooves 144 and 146. Similarly, sidewalls 126 and 130 are provided along their free lateral edges with inwardly turned lips 148 and 150 defining a pair of vertical grooves 152 and 154. Sidewalls or plates 136 and 138 have inwardly turned lips 156 and 158 along one set of lateral edges and outwardly turned lips 160 and 162 along an opposite set of vertical or lateral edges. Lips 156 and 158 define grooves 164 and 166, while lips 160 and 162 form another pair of grooves 168 and 170. 
     As illustrated in FIG. 12, the lips and grooves along the free edges of sidewalls 116, 120, 126, 130, 136 and 138 cooperate to arrest the motion of members 112, 122 and 132 with respect to one another during an opening or pulling apart of receptacle assembly 110 from the collapsed configuration of FIG. 11 to the opened configuration of FIG. 12. In the completely opened configuration of receptacle assembly 110, lips 140 and 142 are seated within grooves 164 and 166, lips 156 and 158 within grooves 144 and 146, lips 148 and 150 within grooves 170 and 168, and lips 160 and 162 within grooves 154 and 152. The interlocking of the lips thus prevents receptacle assembly 110 from being opened beyond a pre-established limit and a concomitant disassembly of the receptacle assembly during a pulling apart operation. 
     Receptacle assembly 110 may be provided with sealing ribs such as described hereinabove with reference to FIGS. 3 and 5. 
     A collapsible receptacle assembly in accordance with the present invention may be made of essentially any durable and substantially rigid material, such as metal and certain hardened resins. 
     Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. Accordingly, it is to be understood that the drawings and descriptions herein are preferred by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
