With reference to FIG. 6, the second mold 74 is attached removably to the second end 62 of the base 58 such that the lip 92 of the second mold 74 engages the annular groove 70 of the base 58 and the annular lip 72 of the base 58 engages the internal groove 90 of the second mold 74, and the branch 88 engages the second end 62 of the base 58. In an embodiment, the receptacle 76 of the second mold 74 is moveable from a first, molding position, in which the receptacle 76 is positioned within the aperture 66 of the base 58 and housed therein, and a second, inverted position, in which at least a portion of the receptacle 76 extends outwardly from the aperture 66 of the base 58 at the second end 62 thereof, and the first surface 78 is exposed externally from the second end 62 of the base 58. The purpose and function of the inversion feature of the receptacle 76 will be discussed below.
In an embodiment, the first mold assembly 12 and the second mold assembly 14 are attached removably to one another, such that the first mold 32 and the second mold 74 connect removably with one another and form a liquid-tight seal therebetween. In this regard, in an embodiment, the bead 94 of the second mold 74 engages the external annular groove 54 of the first mold 32, thus forming a connection and a liquid-tight seal between the annular flange 86 of the second mold 74 and the second annular flange portion 52 of the first mold 32. In an embodiment, a seal is also formed between the branch 88 of the second mold 74 and the top surface portion 56 of the first mold 32. In an embodiment, when the first mold assembly 12 and the second mold assembly 14 are attached to one another, the cavity 40 of the first mold 32 and the cavity 82 of the second mold 74 form a spherical-shaped cavity 96 (see FIG. 6).
In an embodiment, the cavity 96 is adapted to be filled with a fluid to be frozen through the fill hole 84 of the second mold 74. In an embodiment, the fluid is water. In other embodiments, the fluid may be other consumable liquids, such as juices, sodas, or other beverages. In an embodiment, once the cavity 96 is filled, any excess liquid not entering the cavity 96 is collected within the underside of the second mold assembly 14 and can be disposed by turning over the mold 10. In an embodiment, the fill hole 84 is sized and shaped such that the liquid residing within the cavity 96 does not leak therefrom when the mold 10 is turned over, due to the surface tension of the liquid and the internal pressure thereof within the cavity 96. In an embodiment, once the cavity 96 is filled with the liquid, the mold 10 is placed within a freezer at a sufficiently cold temperature for a sufficient period of time to freeze the liquid. When the liquid is sufficiently frozen into an ice sphere 98, the second mold assembly 14 is detached from the first mold assembly 12 by pulling and/or twisting them apart, thereby releasing the connection between the bead 94 of the second mold 74 and the external annular groove 54 of the first mold 32. In an embodiment, when the second mold assembly 14 is detached from the first mold assembly 12, the ice sphere 98 resides within the receptacle 34 of the first mold 32, as shown in FIGS. 7 and 8. To facilitate removal of the ice sphere 98 from the first mold 32, a user may push on the second surface 38 of the receptacle 34 (which is accessible through the aperture 24 from the first end 18 of the base 16) in order to move the receptacle 34 from its first, molding position to its second, inverted position, thereby pushing out and releasing the ice sphere 98 from the first mold 32, as shown in FIGS. 9 and 10. Thus, the ice sphere 98 is removed from the mold 10 in an easy and convenient manner. For example, the first mold 32 does not have to be subjected to running water to loosen the ice sphere 98 therefrom. In an embodiment, once the ice sphere 98 is removed from the first mold 32, the receptacle 34 may be flexed back from its second, inverted position to its first, molding position. As indicated above, the first mold 32 may be removed from the base 16, and the second mold 74 may be removed from the base 58, to facilitate cleaning of such components.
It should be understood that when the second mold assembly 14 is detached from the first mold assembly 12, the ice sphere 98 may happen to reside within the receptacle of 76 of the second mold 74 (not shown in the Figures). In this situation, to facilitate removal of the ice sphere 98 from the second mold 74, a user may push on the second surface 80 of the receptacle 76 (which is accessible through the aperture 66 from the first end 60 of the base 58) in order to move the receptacle 76 from its first, molding position to its second, inverted position, thereby releasing the ice sphere 98 from the second mold 74 (not shown in the Figures) without the need to subject it to running water or the user having to touch or grasp the ice sphere 98 itself. In an embodiment, once the ice sphere 98 is removed from the second mold 74, the receptacle 76 may be flexed back from its second, inverted position to its first, molding position.
It will be understood that the embodiment described herein is one embodiment, and that a person skilled in the art may make many variations and modifications without departing from the spirit and scope of the invention. In an embodiment, the surfaces 36, 78 of the receptacles 34, 76 may be smooth. In other embodiments, the surfaces 36, 78 of the receptacles 34, 76 may be patterned to form different shapes (e.g., soccer balls, basketballs, globes, planets, etc.). In other embodiments, the receptacles 34, 76 may consist of different shapes and sizes (e.g., egg-shaped, etc.). All such variations and modifications, in addition to those described above, are intended to be included within the scope of the claims.
