DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a flexible mould and especially to a disposable mould bag for receiving and retaining therein liquid or the like to be frozen into a plurality of ice pieces by using such a mould bag as well as to closure means for such moulds.
Such moulds or bags are fairly widely used for example for freezing water into "ice-cubes"--not necessarily cube-shaped for use in cooling beverages, as well as for freezing fruit juice or dessert-ice mixtures into so-called "ice lollies". They do, however, suffer from certain disadvantages, that may account for the fact that many people prefer not to use them. Among these disadvantages the following may be mentioned: time-consuming and not always easy, special precautions are taken, such as wearing of protective gloves, and adhere to the ice bodies, not to be discovered before the beverage or ice lolly in question is consumed, or disappear behind a piece of furniture.
According to one embodiment of the invention, the bag constituting the flexible mould may be changed from a compartmented bag suitable for moulding the ice bodies into an uncompartmented bag by suitably manipulating the bag after the completion of the freezing process. The un-compartmented bag will then contain all the ice bodies formed lying loose in the bag, and thus easy to remove, singly or en masse, facilitating the opening of the bag in various ways described below.
Another embodiment of the invention is especially useful for making ice lollies, as the mould may be divided into section, each containing one ice lolly or stick of ice, which sections may be opened gradually when the lollies are being consumed.
According to another embodiment of the invention the strength of the dividing bonding areas will be relatively high when filling the mould with unfrozen liquid, while it will be low, making it easy to disrupt the dividing bonding areas, when the liquid has been frozen to bodies of ice. The force required to disrupt wide bonding areas may be reduced by using a preferred embodiment.
The mould may be manufactured in indefinite lengths and may be cut into lengths suitable for use.
The present invention also relates to a moulding set for freezing small bodies of ice.
The invention will now be explained in more detail with reference to exemplary embodiments of a flexible mould according to the present invention shown in the drawings, in which
FIG. 1 is a diagrammatic view of a so-called freezing bag for "ice cubes", as viewed against one of its flat sides in the unfilled condition,
FIG. 2 is a section along the line II--II in FIG. 1 and showing the compartments of the bag filled with liquid or frozen lumps,
FIG. 3 is a sectional view corresponding to FIG. 2, but showing the bag after disruption of the dividing bonding areas with a number of ice lumps lying loose in the bag,
FIG. 4 is a view according to FIG. 1 on a freezing bag for ice rods or "lollies",
FIG. 5 in two views at right angles to each other shows a section of the freezing bag shown in FIG. 4, containing an ice lolly and opened to give access to the ice lolly,
FIG. 6 in perspective shows a first embodiment of a closure for a mould bag in the open state,
FIG. 7 shows a perspective view of the closure of FIG. 6 in its closed state,
FIG. 8 shows another embodiment of a closure, viewed at right angles to and parallel to the main plane of the closure in the un-stressed condition, respectively, and
FIG. 9 in a somewhat larger scale shows the closure of FIG. 8 in a position, in which it keeps a bag closed.
The flexible mould shown in FIGS. 1 to 3 in the form of a bag 10 of thin sheets 11 and 12 of plastics material, such as polyethylene, is closed on three sides and partly closed on the fourth side. On the fourth side mentioned, shown uppermost in FIG. 1, there is a filling duct 14 for filling the bag 10 with liquid, such as water, to be frozen in the form of pillow-shaped ice lumps 15 shown in FIGS. 2 and 3. The right-hand and left-hand edges of the bag 10 are permanently sealed, such as in first bonding areas 13, that may be
