This non-provisional application claims the benefit under 35 U.S.C. § 119(a) of British application no. GB2113014.1 filed on Sep. 13, 2021 entitled MOULD and whose entire disclosure is incorporated by reference herein.
This invention relates generally to a mould suitable for forming an ice luge. More specifically, although not exclusively, this invention relates to a reusable mould suitable for forming an ice luge (e.g. an ice luge mould), and methods of making the same.
Ice luges are popular for rapidly chilling beverages, for example, at parties and gatherings. Often, alcoholic beverages are served in ice luges such as spirits including vodka and tequila. However, non-alcoholic beverages may also be served in an ice luge.
Ice luges are blocks of sculpted or moulded ice containing one or more channels or lanes having an inlet at or towards the top of the ice luge, and an outlet towards the base of the ice luge, such that the channel or lane slope downwards. In use, a beverage is poured from the entrance of the channel. The liquid travels downwards through the channel, and is cooled as it contacts the ice, to emerge from the lower end of the channel thereby dispensing the liquid into a glass or other receptacle that is placed to receive the chilled beverage.
The fabrication of an ice luge depends on its size and complexity. Large, bespoke ice luges may be sculpted by hand, which requires a large commercial freezer to provide an appropriately sized block of ice, and significant time and labour costs. Smaller ice luge may be formed in a mould. However, often the mould is for single use only, which is wasteful and expensive if multiple ice luges are required.
It is therefore a first non-exclusive object of the invention to provide a mould suitable for fabricating an ice luge, wherein the mould is reusable.
Accordingly, a first aspect of the invention provides a two-part mould suitable for fabricating an ice luge, the mould comprising a first part and a complementary second part configured to form an internal cavity therebetween, the mould further comprising an aperture (e.g. an inlet or a water inlet) and a fluid-tight (e.g. watertight) seal provided around the (e.g. internal) periphery of the first and second part, and a channel former or channel-forming means configured to form a channel in the ice luge.
The first part of the mould and the second part of the mould may comprise body portions, inboard of the periphery. The respective body portions may be shaped to provide mould surfaces to provide a shaped ice luge.
Advantageously, the provision of a fluid-tight seal around the (e.g. internal) periphery of the first and second part enables the first part to be separated from the second part without damage. This enables the mould to be reused to form multiple ice luges.
In embodiments, the aperture (e.g. water inlet) may comprise an aperture located in one of the first part or the second part. In embodiments, the aperture (for example the water inlet) may comprise a valve, e.g. configured to allow water to enter but not to exit the cavity formed between the first part and the second part of the mould. In embodiments, the aperture (e.g. water inlet) may comprise an attachment, e.g. a hose, to enable water to be added to the cavity, e.g. from a tap. A stopper or plug may be provided to non-permanently close the inlet.
The aperture may extend through a body portion of the first part or second part.
In embodiments, the fluid-tight seal provided around the internal periphery may comprise a first part and a complementarily-shaped second part. For example, the fluid-tight seal may comprise a male member, e.g. located on the first or second part, and a female member, e.g. located on the second or first part. In embodiments, the male member may comprise one or more, e.g. one, two, three, or more, projections that extend continuously or non-continuously around the (e.g. internal) periphery, e.g. of the first part. In embodiments, the female member may comprise one or more, e.g. one, two, three, or more rebates that extend continuously or non-continuously around the (e.g. internal) periphery, e.g. of the second part. In embodiments, if plural projections are provided the projections may comprise a first projection part and a concentric second projection part and an n'th concentric projection part. One or more of the first projection part, second projection part or nth projection part may extend continuously or discontinuously. The rebates on the other part will correspond to effect a seal.
In embodiments, the rebates of the female member are sized and/or shaped and/or configured to receive the projections of the male member.
In embodiments, the fluid-tight seal comprises at least one male member located on the first part of the two-part mould, and at least one female member located on the second part of the two-part mould. In an embodiment, the male member may comprise two projections and the female member may comprise two rebates, wherein the rebates are sized and/or shaped and/or configured to receive the two projections to form the fluid-tight seal.
The male member may comprise a proximal part, where it is joined to the mould, and a distal part. The distal part may comprise a free edge and depending wall parts. The distal part (e.g. the free edge and one or more of the depending wall parts) may comprise or have formed thereon a seal material. The female member may comprise a channel formed from a base part and facing wall parts. The channel (e.g. the base part and/or one or more of the facing wall parts) may comprise or have formed thereon a seal material.
The seal material may be a thermoplastic elastomer (TPE) or a silicone rubber. The seal material may be bonded, welded, adhered, co-moulded or over-moulded to or with the male member (e.g. the distal part) and the female member (e.g. the channel part).
The TPE will be selected according to compatibility with the material of the male member (e.g. the distal part) and the female member (e.g. the channel part). The TPE may be selected from styrenic block copolymers (TPS), thermoplastic polyolefinelastomers (TPO), thermoplastic vulcanizates (TPV and TPSiV), thermoplastic polyurethanes (TPU), thermoplastic copolyesters (TPC), thermoplastic polyamides (TPA).
In embodiments, one or both of the first part and second part may comprise an upstanding wall that extends at least partially, e.g. completely, around the periphery of one or both of the first part and second part.
Advantageously, the upstanding wall provides a further sealing means to retain water inside the mould before it is frozen.
One or both of the first part and the second part may comprise a rim extending around its external periphery.
One or both of the first part and the second part may comprise one or more securements or securement means. For example, one or both of the first part and the second part may comprise more than 5, more than 10, more than 15 or more than 20 securement means. For example, one or both of the first part and the second part may comprise less than 30, less than 25, less than 20, less than 15 or less than 10 securement means. For example, one or both of the first part and the second part may comprise 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 securements means. The number of securement means may be chosen dependent on the overall size of the mould.
The securements or securement means may be a fastener, for example a clip, catch, hook or the like, to further secure the first part of the mould to the second part of the mould.
A first end of the securement means may be attached to the first part of the mould. A first end of the securement means may be attached to the second part of the mould. The or each securement means may be attached/located on the upstanding wall of one or both of the first part and the second part.
The or each securement means may be evenly distributed around the periphery of one or both of the first part and the second part. The or each securement means may be unevenly distributed around the periphery of one or both of the first part and the second part.
In an embodiment the securement means, e.g. fastener, e.g. clip, catch, hook or the like, comprises a male protruding member. The or each male protruding member may be configured to fasten over a portion, for example a rim, that extends around the external periphery of the opposing part of the mould. For example, a first end of the securement means may be attached to the first part of the mould and the male protruding member may be configured to fasten over the rim that extends around the external periphery of the second part of the mould, and vice versa.
In embodiments, one or both of the first part and the second part may comprise a protrusion. The or each protrusion may be configured to assist a user in separating the first part from the second part.
Where both the first part and the second part comprise a protrusion, the protrusion on the first part may be offset with respect to the protrusion on the second part. Offsetting the protrusions may enable a user to more easily grasp each of the protrusions.
In an embodiment there may be provided a plurality of protrusions, e.g. 1, 2, 3, 4 or 5 protrusions may be provided on one or both of the first part and the second part.
In embodiments, the or each protrusion may be provided on the upstanding wall of one or both of the first part and second part.
In embodiments, the channel-forming means may be integrally formed with one or both of the first part and/or the second part.
In embodiments, the channel-forming means may comprise a portion located within one or both of the first part and/or the second part, which is configured to form a channel on or in the ice luge. In embodiments, the channel-forming means may be configured to form a channel on the external surface of the ice luge.
In embodiments, the channel-forming means may be separable from the first part and/or second part of the mould. In embodiments, the channel-forming means may be removable from the formed ice luge.
In embodiments, the channel-forming means may comprise an elongate body, for example an elongate solid body or tube, e.g. a flexible tube, for example a plastic tube. In embodiments, the channel-forming means may be configured to form a channel internally within the ice luge.
Advantageously, the use of a channel-forming means, e.g. an elongate body or tube, which is removable from the formed ice luge enables the mould to be reused to form multiple ice luges.
In embodiments, the channel-forming means, e.g. an elongate body or tube, may be fabricated from a polymeric material, preferably a food grade polymeric material, for example, one or more of a thermoplastic elastomer (TPE), silicone (e.g. silicone rubber), polyamides (e.g. Nylon), polyethylene (e.g. LDPE), polypropylene, polyethylene terephthalate (PET) and so on.
Whilst the channel-forming means may comprise an elongate solid body it is preferred that it comprises an elongate hollow body (i.e. a tube). It has been found that elongate tubes are easier to remove from the moulded ice due to a tube's ability to change shape when a pulling force is exerted thereon, thereby causing the surface of the tube to move away from the facing surface of the ice.
In embodiments, either or both of the first part and/or the second part may comprise one or more receiving apertures. The one or more receiving apertures may be configured to receive a first end or a second end of a channel-forming means, e.g. a tube. In embodiments, the first part or the second part may comprise a first receiving aperture and a second receiving aperture, wherein the first receiving aperture is positioned towards a first end and the second receiving aperture is positioned towards a second end of the first part or the second part, such that the resulting channel in the ice luge slopes downwardly in use. In embodiments, a first end of a channel-forming means, e.g. a tube, may be located (e.g. removably and/or sealingly located) through the first receiving aperture, and a second end of a channel-forming means, e.g. a tube, may be located (e.g. removably and/or sealingly located) through the second receiving aperture, to form a channel within the ice luge for receiving liquid, in use. In this way, once the channel-forming means has been removed (or if hollow may have been retained) liquid, e.g. a beverage, may be poured into the formed channel of the ice luge at the entrance, and the liquid may flow down through the channel to emerge from the exit of the channel at a lower temperature.
The channel-forming means may be sealingly located within the first part and/or second part. Advantageously, the channel-forming means is sized and configured to seal the first and second receiving aperture in the first part and/or second part, thereby to prevent fluid from egressing during use.
In an embodiment the channel former or channel-forming means is associated with one part of the mould (i.e. the first or the second part of the mould) and the aperture is associated with the other part of the mould (i.e. the second or first part of the mould). This may allow the channel former or channel-forming means to be located closer to the centre of the mould in use. For example, when filling the mould with fluid (e.g. water) the aperture will be uppermost. In order to ensure easier removal of the mould the water may not be filled to overflow the aperture (providing room for the ice to expand upon freezing). Accordingly, the part of the mould associated with the channel-former or channel-forming means may have a larger volume than the part associated with the aperture.
In embodiments, the mould may be fabricated from a flexible material. Alternatively, the mould may be formed from a rigid material. Advantageously, the use of a flexible material enables the ice luge to be more easily removed from the mould without damaging the mould, so that it can be reused. The facing parts of the mould may have a reinforced lip portion. For example the lip portion may be thicker than the body of the mould, and/or may have other reinforcements.
In embodiments, the mould may be fabricated from a polymeric material, for example a food grade polymeric material. The polymeric material may be selected from one or more of a thermoplastic elastomer (TPE) or silicone (e.g. silicone rubber), polyamides (e.g. Nylon), polyethylene (e.g. LDPE), polypropylene, polyethylene terephthalate (PET) and so on.
The mould according to the invention may be shaped to form any suitable three dimensional shape. The shape formed by the first part and the second part may be similar or dissimilar. The mould may comprise decorative projections and/or rebates on its surface to provide an aesthetically pleasing shape or pattern. In embodiments, the mould may be shaped into a novelty item. In embodiments, the mould may be shaped to form an animal or creature, e.g. a dragon. In embodiments, the mould may be shaped to form three dimensional letters or numbers.
In embodiments, the mould may comprise strengthening means and/or stabilising means, for example, on an external surface of one or both of the first part and second part. In embodiments, the strengthening means may comprise upstanding walls configured to provide strength and/or stability to the shaped mould. In embodiments, the stabilising means may comprise one or more, e.g. two or three or more, projections configured to enable the mould lie in a position wherein the seam between the first part and the second part is substantially level.
In embodiments, the mould may have a height, a width and a depth. The height may be greater than the width and/or the depth. The width may be greater than the height and/or the depth. The depth may be smaller than the height and/or the width.

Advantageously, the mould may be dimensioned such that it can be placed in a domestic freezer for home use of an ice luge.
In use, to form the ice luge, the first part and the complementary second part may be placed together to form a fluid-tight seal, and optionally a separate channel-forming means may be added to the cavity formed between the first part and the second part. The user may then add water to fill the interior of the mould via the inlet. The user may then fasten any securement means to secure the first part and complementary second part of the mould together. The filled mould is then placed in a freezer for sufficient time to freeze the water within the mould. Once the water has frozen, the resulting ice luge may be removed from the mould by separating the first part from the second part. Separating the first part from the second part may comprise grasping a protrusion located on the first part and a protrusion located on the second part and pulling them apart. Optionally, the channel-forming means may be removed from the ice luge to form a channel in the ice luge.

The mould 101 has a height of approximately 360 mm, a width of approximately 270 mm, and a depth of approximately 160 mm. Advantageously, the mould 101 of this embodiment is dimensioned such that it can be placed in a domestic freezer for home use of an ice luge.
In use, to form the ice luge, the first end of the channel-forming means 132a is located in (or at least is located to communicate with) the first aperture 133a of the second part 103, and the second end 132b of the channel-forming means 132 is located in (or at least is located to communicate with) the second aperture 133b of the second part 103. The first part 102 and the complementary second part 103 are placed together, and are closed to form a cavity therebetween. A fluid-tight seal is formed when the rebate of the female member 131 of the second part 103 is received within the projection of the male member 121 of the first part 102. The user then fastens the clips 141 to further secure the first and second parts 12, 103 of the mould 101 together. The user then adds water to fill the cavity formed between the first part 102 and the second part 103 of the mould 101 via the water inlet 120. The filled mould 101 is then placed in a freezer, with the water inlet 120 facing upwards, for sufficient time to freeze the water within the mould. Once the water has frozen, the resulting ice luge may be removed from the mould 101. The user may grasp the protrusions 140a, 140b and pull them apart so as to separate the first part 102 from the second part 103. The channel-forming means 132 is removed from the ice luge to form a channel in the ice luge.
