AI Technical Summary

Benefits of technology

The apparatus efficiently converts liquids into semi-frozen or frozen beverages at a lower cost, making it suitable for domestic use and capable of producing a variety of slurry-style drinks, including cocktails, while ensuring safety and environmental sustainability.

Problems solved by technology

However, these machines are expensive to manufacture and install; and are not suitable for, e.g., domestic use; or for the manufacture of a wide range of “slurry”-style beverages, including alcoholic beverages such as cocktails.
While the apparatus disclosed in PCT / AU2005 / 001895 is effective in converting the liquid in the container into a semi-frozen slurry or the frozen ice particles, the cost of manufacture results in a product which is too expensive for the intended market; and particularly is too expensive for manufacture and sale as a disposable or “throw-away” item.

first embodiment

[0037]Referring to the invention illustrated in FIGS. 1 and 2, the apparatus 10 incorporates a cup 20, a cover 30 and an optional strainer 40′.

[0038]In this embodiment, the container 20, the cover 30 and the strainer 40 are injection-molded from transparent or translucent plastics-material, e.g., polyethylene.

[0039]The container 20 is in the form of a cup with a frusto-conical side wall 21 terminated by a bottom wall 22 at one end and by an open mouth 23 at the other end. One or more screw threads 24 (or optional bayonet-coupling components) are provided on the inner face of the side wall 21, adjacent the mouth 23, to releasably receive complementary screw-threads (or bayonet-coupling components) on the cover 30 to enable releasable engagement between the container 20 and the cover 30. A sealing surface or ring 25 may be provided within the open mouth 23 (and preferably above the screw-threads 24) to ensure sealed engagement between the container 20 and the cover 30.

[0040]The cover ...

second embodiment

[0043]Referring to the invention illustrated in FIGS. 3 and 4, the apparatus 110 has a container 120, manufactured from thin stainless steel sheet, with a cylindrical side wall 121 terminated at one end by a bottom wall 122 and at the other end by an open mouth 123.

[0044]The cover 130 is formed from transparent or translucent plastics material, e.g., as hereinbefore described with a peripheral rim 133, provided with an internal sealing ring 134, arranged for sealing / frictional engagement with the portion of the side wall 121 of the container 120 adjacent the open mouth 123.

[0045]The freezing device 150 has a closed body 151 of spherical shape, formed of a thin plastic-material (e.g., polyurethane), with a resiliently deformable wall 152 and where the internal capacity 153 is 75-90% filled with the refrigerant material 154 comprising, e.g., a 20% salt / 80% water (w / w) mixture.

[0046]The refrigerant material 154 may be cooled to a temperature at or below −18° C. in a refrigerated freeze...

fourth embodiment

[0058]Referring now to the fourth embodiment illustrated in FIGS. 6 to 8, the apparatus 310 has a container 320 and cover 330 substantially as hereinbefore described.

[0059]The freezing device 350 is of cylindrical shape, and the cylindrical side wall 352 can “concertina”, as shown in FIG. 7, to displace the ice crystals 361 formed (from the liquid 360) thereon, when the container 320 is shaken in the direction of arrow D, to cause the end walls 353, 354 of the freezing device 350 to impact the container 320 and cover 330.

[0060]In a modified form of this embodiment, the container 320 may be provided in the shape of a soft drink container, and the freezing device 350 could also be made in the same shape to make a frozen beverage from a known soft drink supplier.

[0061]As hereinbefore described, the freezer devices may have a range of internal capacities, from 10 milliliters (10 ml) to 50 liters (50 L) or larger, depending on the intended volume of liquid to be at least semi-frozen to a...

Abstract

A frozen beverage device has a container and sealable cover to convert a liquid, such as a non-alcoholic or alcoholic beverage into an at least semi-frozen slurry containing ice crystals. Freezing devices, which may have a range of shapes, contain refrigerant to form a thin layer of ice / ice crystals on the deformable walls of the freezing devices, the ice crystals being released therefrom due to agitation of the liquid by shaking / rotation and / or squeezing on the container and / or cover.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application of pending U.S. patent application Ser. No. 12 / 735,212, filed Sep. 27, 2010 for FROZEN BEVERAGE DEVICE, which claims the priority of International application No. PCT / AU2008 / 001923 filed on Dec. 22, 2008, which claims the priority to Australian Applications 2008904877 filed on Sep. 19, 2008 and 2007907090 filed on Dec. 24, 2007 all herein fully incorporated by reference.BACKGROUND. OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a frozen beverage device; and to methods of producing frozen beverages using the device.[0004]The invention is particularly suitable for, but not limited to, apparatus for making frozen beverages in semi-frozen “slurry” or “slushie” form; and to such a frozen beverage device which may be used as a toy or plaything.[0005]Throughout the specification, the term “slurry” shall be used to include a mixture of liquid / semi-liquid, liquid / frozen...
