Description

ICE BLOCK APPARATUS
BACKGROUND TO THE INVENTION
THIS invention relates to an ice block apparatus.
At a domestic level ice blocks are traditionally formed by filling a preformed ice tray in situ with water and placing the tray in a freezer. After the water has frozen ice blocks can be dispensed from the tray. Although the traditional process is simple enough, it has the disadvantage that it can be quite difficult to transport an ice tray full of water to the freezer and then to stack the ice tray in the freezer without spillage of water. SUMMARY OF THE INVENTION
According to the invention there is provided an ice block apparatus comprising a moulded plastics tray providing a plurality of spaced apart, open-topped compartments, liquid in the compartments and a peelable plastics film covering the tray and sealing the individual compartments.
Conveniently, the tray is rectangular in shape with a plurality of compartments arranged in parallel rows, the apparatus including at least one line of weakness between adjacent rows at which the rows can be separated from one another.

DESCRIPTION OF EMBODIMENTS
The apparatus 10 illustrated in Figure 1 includes a one-piece moulded plastics tray 12 which provides a large number of compartments 14 arranged in parallel rows 16. The compartments are separated from one another by upstanding walls 18 and 20, and each compartment 14 is filled with natural spring water to a level at or very near the upper edges of the walls which bound it. It will be noted, from Figures 2 and 3 in particular, that the upper edges of the walls 18 and 20 of all the compartments lie in a common plane.
The plastics of which the tray 12 is moulded is light-transmitting, i.e. transparent or translucent.
In the preferred embodiments the plastics material of which the tray 12 is moulded is a laminate of semi-rigid PET (polyethylene terephthalate) and food-grade, peelable PVC (polyvinyl chloride) with the PVC layer facing inwardly to form the inner surface of the compartments 14. The apparatus 10 also includes a peel-off film or foil 22 which covers the entire tray 12. The film is in the form of a sheet of clear, flexible plastics material which is adhered to the upper edges of the walls 18 and 20 and to the outer, bounding edge of the tray 12 to seal the compartments 14 from the ambient atmosphere and from one another.
In the preferred embodiments, the film 22 is a laminate of peelable, food- grade PVC and flexible nylon or PET. The PVC layer faces downwardly, i.e. towards the tray 12. It will accordingly be understood that the PVC layers of the laminates forming the tray 12 and the film 22 are in contact with one another.
The tray 12 is manufactured, and the compartments 14 filled with spring water, by vacuum forming in a conventional form and fill process. After the form and fill procedure the film 22 is laid over the filled tray and adhesion between the contacting PVC layers around the boundary of the tray 12, and at the upper edges of the walls 18 and 20, is promoted by application of heat. Thereafter on the production lines of weakness, in this embodiment perforated lines 24, are formed at positions corresponding to the upper edges of every second wall 18.
In use, the apparatus 10, with the compartments 14 of the tray 12 already charged with spring water and the film 22 adhered in position, is placed in a freezer in the manner of a conventional ice tray. After the water has frozen, it is a simple matter to extract ice blocks from the tray. One or more strips 26, each including two rows 16 covered by the associated portion of the film 22, can be torn from the remainder of the apparatus by application of a suitable tearing force at a chosen line of weakness 24. Thereafter as much of the film 22 as is necessary to expose a required number of compartments 14 can be peeled back, this being facilitated by the peelable nature of the PVC which is used in the laminates that form the tray and film.
The exposed ice blocks can then be ejected individually from the relevant compartments. This may, for instance, be achieved by pressing externally on the base 28 of each compartment 14 to deform the plastic and hence press the ice block out of the compartment. It is preferred that the PET/PVC laminate that forms the bases 28 be thinner, and hence more easily deformed by a manual pressing action to eject the ice cubes, than the laminate forming the remainder of the tray.
The remainder of a strip 26 from which ice blocks have not been ejected can be replaced in the freezer for later use. After the strip has been used up, it is merely disposed of. It is not the intention that the ice tray 12, or the strips 26 thereof, be re-used.
Although the illustrated embodiment has two rows 16 per strip 26, it will be understood that there may be only a single row or more than two rows per strip. It is also within the scope of the invention for there to be lines of weakness, possibly perforated lines, at the upper edges of at least some of the walls 20 to enable individual compartments or groups of compartments to be torn transversely off a strip 26 or directly off the apparatus 10.
In the vacuum forming process, the base 28 of each compartment 14 may be formed, in relief, with the negative of a logo, trade name, advertising message or other indicia which will appear embossed or recessed in the ice blocks which are formed. An example of this is indicated with the numeral 30 in Figure 5. which shows a perspective view of a typical ice block formed with the apparatus of the invention. The irregularities in the base attributable to the presence of the indicia can, when the ice block floats in an appropriate liquid, pick up ambient light and direct it randomly, by reflection and/or refraction, into the interior of the ice block, contributing to illumination of the block and readability of the indicia.
It was mentioned previously that in the preferred embodiment the base 28 of each compartment be thinner and hence more easily deformable, than the remainder of the tray. This facilitates the manual ejection of the ice blocks. In addition, with suitably thin and deformable base material it is possible to eject each block without damaging relieved indicia formed on the base thereof, even if the indicia themselves are small or finely defined. Where indicia are to be included on the bases of the blocks, the thickness and flexibility of the bases of the compartments will be selected such that there is sufficient rigidity to maintain the required shape of the block and indicia when the tray is charged with liquid but insufficient to result in damage to or breakage of the indicia when manual pressure is applied to eject the blocks.
Figure 6 shows a portion of the length of a continuous tray moulding 30 formed in the vacuum moulding stage of the form and fill process. As illustrated here, the side walls of the compartments 14 have fluted profiles. This feature both strengthens the walls against outward bowing when the compartments are charged with water and results in the formation of aesthetically pleasing ice blocks, a typical one of which is shown in Figure 7. The continuous moulding 30 of Figure 6 has a total of eight rows 32 of compartments 14. At the end of the production line, after charging of the compartments and application of the sealing film, the moulding 30 is slit longitudinally along a slit line 34 and also along slit lines 36 every eight compartments 14. Thus the products formed in the process are individual ice trays each consisting of thirty-two compartments 14, in four rows, charged with water and covered and sealed by a sealing film.
It will be understood that, if required, the continuous moulding of Figure 6 can optionally be slit along any other longitudinal or transverse lines. Lines of weakness at which individual rows or groups of rows of compartments can be separated from the remainder of the tray can also be provided if required.
Apart from the convenience of the apparatus, it will be appreciated that it has the benefit that the volume of water in each compartment is effectively hermetically sealed, thereby reducing the chance of bacterial or other pollution affecting its quality and that of the ice which is eventually formed after freezing.
Although specific reference has been made to spring water and ice, it will be understood that in other embodiments the compartments of the ice tray could be charged with liquids other than water. The term "ice" is used for convenience and should be interpreted accordingly.
