Description
BAKING APPARATUS
This invention relates to baking apparatus and in particular to baking containers.
Back2round of the Invention Cakes vary considerably in their baking times, key influences on the baking times being the size of the cake and the density of the ingredients. Thus light cakes such as sponge cakes and Victoria sandwich cakes can be baked in as little as 15 to 35 minutes whereas chocolate cakes can take up to an hour or more. Denser cakes such as fruit cakes and Madeira cakes can require baking times of over an hour and a half at temperatures of 180 °C.
Apart from the prolonged baking times (and hence the increased energy costs involved in the baking process), a potential problem with the longer-bake cakes is that they can dry out and fonn a hard crust on the outside. In commercial baking, this problem can be avoided by using steam ovens but the average domestic household is unlikely to possess a steam oven. Therefore, baking cakes such as Madeira and fruit cakes in a domestic context can be somewhat problematic.
Summary of the Invention
The invention sets out to provide a baking system that enables a range of different types and sizes of cake to be produced using domestic cooking appliances whilst reducing cooking times and/or reducing crust formation for longer bake cakes.
It has been found that by providing a baking container (e.g. baking tin) with a lid formed from a silicone material and preferably also an outer skin or liner formed from a silicone material, moisture evaporating from the cake mixture as it cooks is retained more effectively within the baking container leading to reduced cooking times and reduced crust formation.
Accordingly, in a first aspect, the invention provides a baking container comprising a container body and a lid, characterised in that the lid is formed from a heat resistant silicone material.
Heat resistant silicone materials are known to have been used in cooking and baking and bun or muffin moulds formed from silicone materials are known. The chief benefit of using a silicone bun or muffin mould is that the silicone is non-stick and therefore the buns or muffins can be removed easily after baking. In addition, the flexible resilient nature of the silicone means that the bun or muffin can be more easily ejected from the mould. However, so far as the applicant is aware, the use of silicone lids on baking containers, and the consequential advantages in terms of reduced cooking times and reduced crust formation, have not previously been disclosed to the public.
The container body of the baking container of the invention preferably comprises inner and outer side walls, one of the inner and outer side walls being formed from a heat resistant silicone material and the other of the inner and outer side walls being formed from a structurally more rigid material (relative to the silicone material) such as a metal. Examples of metals are food grade metals such as aluminium and stainless steel.
In one embodiment, the inner side wall(s) is/are constituted by a frame formed from a metal material such as aluminium and the outer side wall(s) is formed from a silicone material.
Within this embodiment, the baking container may have a base formed from inner (i.e. upper) and outer (i.e. lower) base members wherein the outer base member is formed from a silicone material and the inner base member is formed from a metal material such as aluminium or stainless steel. Preferably the silicone outer side wall(s) and the silicone outer base member are integrally formed (e.g. integrally moulded) and thus form a continuous silicone skin around the outside of the container body.
The metal frame forming the inner side wall is typically formed from a plurality (e.g. two, three or four, and preferably four) frame members that can be detachably connected together. By making the frame members detachable, the frame can be dismantled and the silicone outer skin removed more easily, for example for cleaning. The outer silicone skin can therefore be formed so that it abuts firmly against the inner frame and thereby holds the frame members firmly in place.
The frame members can advantageously be connected together by means of a hinge pin and socket connection between the members wherein a hinge pin on one frame member engages a socket on another frame member.
In one specific embodiment the frame is of rectangular (e.g. square) form and comprises two pairs of frame members, one pair of frame members having a hinge pin at each end thereof and the other pair having a socket formation at either end thereof. In an alternative embodiment, the frame is of rectangular form and comprises four frame members, each having a socket formation at one end and a hinge pin at the other end.
As an alternative to a rectangular frame, the frame may be circular and may, for example be formed from two or more frame members. In one embodiment, the frame comprises two semicircular frame members detachably connected together.
Where the base is formed from inner and outer base members, the inner (i.e. upper) base member is preferably provided with means for holding the frame and frame members in place. Thus, for example, the inner base member may have upstanding retaining flanges extending along its edges, the retaining flanges and frame members being configured so that the frame sits inside the retaining flanges.
In order to allow cakes of different sizes to be baked within the baking container, one or more partitions or divider plates may be used to divide the interior of the container into a plurality of compartments. The baking container is preferably provided with means for attaching the partitions or divider plates at a plurality of locations on the walls of the container (e.g. the inner wall or frame). Such means can take the form of a plurality of slots in the frame members that can be engaged by connecting tabs or hooks on the divider plates.
The lid of the baking container is formed from a silicone material. The lid may be stiffened by one or more stiffening members such as stiffening ribs or like structures. The stiffening members (e.g. ribs) are preferably formed integrally (e.g. by moulding) with the lid.
The silicone material used in the baking containers of the present invention is a heat resistant silicone polymer, typically an elastomeric silicone polymer, which is resistant to the temperatures used in baking. For example, the silicone polymer can be resistant to temperatures in excess of 250 °C. Such polymers are commercially available.
In another embodiment, the baking container of the invention comprises a container body having an inner side wall and base formed from a silicone polymer material and an outer side wall surrounding the inner side wall and being formed from a metal material.
The baking containers of the invention can be used to bake cakes and dough based foods such as bread. In each case, by enclosing the dough or cake mix within a silicone enclosure, baking times are reduced and crust formation is minimised.
Accordingly, in another aspect, the invention provides a method of baking a cake or dough-based food, which method comprises placing an uncooked cake mix or dough into a baking container according to the invention, closing the container by placing the silicone lid thereon, and placing the container into an oven for a period of time sufficient to bake the cake or dough based food.
For storage purposes, one or more smaller baking tins (e.g. round baking tins) can be nested within the baking container and the whole optionally presented in a box or other outer protective container.
Therefore, in a further aspect, the invention provides a baking container assembly comprising an outer protective container (e.g. a box with a lid) having disposed therein a set of nested baking tins comprising a rectangular (e.g. square baking tin) and, arranged within the rectangular baking tin, one or more round baking tins (e.g. two or more nested round baking tins). The rectangular baking tin is preferably a baking container as hereinbefore defined or as described below in the examples and, as such, is provided with a lid formed from a heat resistant silicone material.

Detailed Description of the Invention
The invention will now be illustrated, but not limited, by reference to the specific embodiments shown in the accompanying drawings.
A baking container according to a first aspect of the invention is illustrated in Figures 1 to 12. The baking container 2 comprises a container body 4 and a lid 6.
The lid 6, which is formed from a heat resistant silicone material, has integrally moulded stiffening strips 7 extending along its top surface.
The container body 4 is of square cross section and has an outer skin formed from a heat resistant silicone material which consists of a floor 8 and side walls 10 which are integrally moulded with the floor 8. The silicone outer skin can be seen more clearly in Figure 5.
Held firmly inside the silicone outer skin 8, 10 are a rectangular base plate 12 and a rectangular frame 14, both of which are formed from a more rigid (than the silicone skin) material such as a metal (e.g. aluminium or stainless steel). The base 12 and frame 14 provide support for the otherwise flimsy silicone skin.
The base plate 12 has upturned flanges 16 on each side thereof (see Figure 5 in particular), the flanges extending along the greater part of the length of each side so as to form a tray. The flanges 16 are held within a recess extending around the lower edge of the side walls 10 of the silicone outer skin, as can be seen more clearly in Figure 5.
The upper surface of the base plate canies etched or machined markings (shown as circles and lines) to indicate different cake sizes. The markings may be accompanied by Figures and letters (not shown) and can be used to gauge the size of round cake tins without the need to resort to the use of a ruler.
The rectangular frame 14 rests on the base plate 12 and sits firmly inside the flanges 16. The frame 14 is formed from two pairs of frame members 18 and 20 which are connected together at their ends by means of a hinge pin and socket anangement.
As shown in Figures 6 to 9, one pair of frame members 18 have hinge pins 19 at both ends whereas the other pair of frame member 20 have a socket formations 21 at both ends for receiving the hinge pins of frame members 18. The socket formations 21 are created by rolling the edges of the frame members into a circular form. The hinge pin arrangement is formed in a similar way but, in this case, a pin is secured inside the rolled edge.
Each frame member 18, 20 is provided with a plurality (five in the embodiment shown) of short slots 22 extending downwardly from the upper edge of the frame member.
The baking container is provided with a pair of divider plates 24 and 26 for dividing the interior of the frame into baking areas of different sizes. Each divider plate is formed from a metal such as aluminium or stainless steel and is provided with a plurality (in this case five) of vertical slots. In divider plate 24 (see Figure 11), the slots 25 extend from the lower edge of the plate to a point half way up the plate. In divider plate 26 (Figure 12), the slots 27 extend from the upper edge of the plate to a point half way down the plate.
Each divider plate has a pair of "ears" or bent tabs 30 which serve to hook into the slots 22 in the frame members 18, 20 as shown in Figures 4 and 10 to hold them in place. A single divider plate may be used to divide the interior of the baking container into a two baking compartments. Alternatively, the two divider plates may be slotted together and both fitted into the frame as shown in Figures 4 and 10 to provide four baking compartments.
It will thus be appreciated that the divider plates may be used to enable cakes of varying sizes to be baked using a single container.
In use, the interior of the frame (or one or more of the compartments formed by the divider plates) is typically lined with greaseproof paper or silicone-coated baking parchment and a cake mixture deposited in the lined frame or compartment. The silicone lid 6 is then fitted in place and the cake mixture is baked in an oven in the usual way.
It has been found that by using the baking container of the invention, baking times are reduced and the resulting cake is more moist.
Because the cake mixture is encased within a silicone enclosure formed by the silicone outer skin 10,12 and the lid 6, a greater proportion of the water evaporating from the cake mixture during the cooking process is retained within the baking container than is the case with a conventional cake tin. Consequently, it is believed, the interior of the container takes on the characteristics of a steam oven and this is believed to result in the reduced baking times. Moreover, the surface of the cake remains moist and does not form the hard crust often associated with cakes baked in conventional cake tins.
A second embodiment of the invention is shown in Figures 13 to 15. In this embodiment, the baking container comprises a pot 102 of circular cross section and a lid (not shown). The pot 102 is formed from a heat resistant silicone material.
The rim of the pot 102 is recessed on its underside to define an annular channel 104. A ring or band 106 formed from a metal material such as aluminium of stainless steel surrounds the enclosure body 102, the upper edge of the ring or band being held within the annular channel 104.
The baking container of Figures 13 to 15 can be used without the lid in conventional fashion or it can be used with the lid in place. Alternatively, the baking container of Figures 13 to 15 can be placed inside the container of Figure 1 and the lid 6 placed over the top.
For storage purposes, the baking container of Figures 13 to 15 can be placed within the container of Figures 1 to 12 and covered by the lid 6. Two or more baking containers of the type shown in Figures 13 to 15 can be placed in nested fashion within the square baking container of Figures 1 to 12. For additional protection, the nest of baking containers can be enclosed within a storage box together with baking tools and utensils such as measuring spoons, storage racks, sieves and the like.
Thus, as will be appreciated from the above, the invention provides a complete cake baking system able to be used to bake a wide variety of different sizes, and shapes and types of cake.
Eiuiva1ents It will readily be apparent that numerous modifications and alterations may be made to the specific embodiments of the invention described above without departing from the principles underlying the invention. All such modifications and alterations are intended to be embraced by this application.
