Constructive layout applied to ice tray
View Patent ↗An ice tray is provided, which includes a tray used to obtain pieces of ice with spherical geometry. The ice tray includes a base and a cover, provided with a first and a second semi-spherical cavity, respectively, which connect to form a spherical cavity, appropriately suitable for obtaining spherical geometric pieces of ice.
1. A stackable ice tray, suitable for forming pieces of ice with a spherical geometry, comprising:
a substantially cylindrical base having an upper region, lower region, and central region, wherein a first semispherical cavity is located in the central portion, and wherein the lower portion has two semicircular recesses on diametrically opposite sides of the base;
a cover having a second semispherical cavity and a surrounding ring positioned externally to the second semispherical cavity, wherein the surrounding ring of the cover has two diametrically opposed tabs projecting from the cover;
wherein the first and second semispherical cavity connect to form a single spherical cavity capable of holding water when the cover is placed onto the base.
2. The stackable ice tray of claim 1 , wherein the two diametrically opposed tabs projecting from the cover may engage two semicircular recesses of a lower portion of a second stackable ice tray of the same design.
3. The stackable ice tray of claim 2 , wherein engagement between the two diametrically opposed tabs from the cover and the two semicircular recesses of the lower portion of the second stackable ice tray creates a gap suitable for the circulation of convective currents between the stackable ice tray and the second stackable ice tray.
4. The stackable ice tray of claim 2 , wherein the upper portion of the base has a rim comprising a step and the step acts as a support for front and rear sides of a lower portion of a base of the second stackable ice tray, wherein the front and rear sides are the sides not including the two semicircular recesses.
5. The stackable ice tray of claim 1 , wherein the central portion of the base has a smaller circumference than the upper portion and the lower portion.
6. The stackable ice tray of claim 1 , wherein the two diametrically opposed tabs projecting from the cover have a saddle-shaped curvature.
7. The stackable ice tray of claim 1 , wherein the cover has a hole surrounded by a circular elevation.
8. The stackable ice tray of claim 1 , wherein the cover is at least substantially inside the base when the cover is placed onto the base and the spherical cavity is formed.
9. The stackable ice tray of claim 8 , wherein the two diametrically opposed tabs projecting from the cover extend out of the base.
10. The stackable ice tray of claim 1 , wherein pressure applied to the two diametrically opposed tabs projecting from the cover releases the cover from the base.
