summanLikihgjnyantsni According to the present invention there is provided an oven liner device comprising plural heat resistant panels wherein one or more panel comprises two or more perimetric joins and at least one panel comprises a fan cover.

In this way the device may provide a liner for an oven, which liner may in some embodiments comprise a semi-permanent or repeat-use liner for the interior of the oven.

In some embodiments the device comprises an oven securement mechanism. Such mechanism may comprise a single part mechanism.

For example the mechanism may comprise the formation of the device in use. Such mechanism may be provided by inherent bias within the device, for example such that the panels are arranged to be pushed against interior walls of the oven in use, so as to hold the device in place within the oven.

In other embodiments the mechanism may comprise additional or separate mechanism parts. For example the mechanism may comprise screws.

In some embodiments the mechanism comprises side panels that comprise existing screw holes that allow the liner to be mounted behind oven racks, creating a permanent, secure fixing.

In still further embodiments in addition or the alternative the mechanism may comprise displaceable mechanism parts, such as hinged flaps or tabs, which tabs may be displaced to engage with other parts of the device and/or the oven interior so as to hold the device in place.

In some embodiments the joins may comprise permanent joins, for example hinges or living hinges. In other embodiments the joins are formed in use, for example wherein the device comprises panels for assembly so as to interconnect of interfit.

In some embodiments the device comprises four panels. Such panels may be joined together permanently with three hinges. Such panels may be joined together in use, for example interlocking slots or male and female parts. In some embodiments the device comprises five panels, namely a base panel, two side panels, a top panel and a rear panel. In some embodiments the device comprises more than one set of interconnected panels, for example wherein the panels comprise permanent or temporary joins.

In some embodiments the panels may be formed by aluminium, or metal or polymer. In some embodiments the panels comprise one or more vents, perforations or through-holes, so as to permit passage of heat and/or vapour.

In some embodiments the device may deliver a complete oven liner using as few parts and processes as possible whilst still offering optimum coverage for protection.

Press-stamping may also allow for unique branding solutions and placement whereby some such embodiments are embodied by creating the device out of a single sheet of stamped aluminium which may be supplied in a flat packed form and unfolded into a final shape.

In this way manufacturing the device out of a single aluminium sheet reduces both manufacturing and assembly costs, allowing the device to be sold at a lower retail price.

The device may thereby comprise assembly sections, enabling a standalone assembly, which sections are arranged to interact or interface. For example in some embodiments a right side panel may comprise a flange section that slots into a slot section in the top panel, enabling support for the top panel without having to fix it to an oven interior.

The device may comprise panels with edges hemmed to increase strength and rigidity, making the device less prone to flexing and warping. Furthermore in such embodiments hemming the edges reduces the risk of a user cutting themselves, since the edges are folded.

In some embodiments the outside of the device may comprise a matte or satin finish with the inside having a reflective or semi-reflective coating or finish.

A reflective coating or finish may advantageously reflect heat and/or make it easier for a user to see what is inside the oven.

Some embodiments may focus on providing an adaptable solution that can be customised to various oven sizes.

For example in a flat pack form, the device may be provided in a kit of panels that are slot together to create an embodiment according to dimensions required.

In some such embodiments the edges of each panel may be crimped and folded. This allows panels to slot together whilst also increasing the rigidity of each panel. Furthermore, in some embodiments this may allow for more adaptability in regards to different oven sizes, where instead of creating a single shape, individual panels may be changed to adapt the overall size.

Some embodiment may comprise a perforated fan cover or otherwise displaceable fan cover wherein if a user does not wish to use the fan cover, they can tear along perforations, allowing the user to remove a part.

In some embodiments a drip tray may be provided that is separate and/or separable, such that the drip tray is displaceable for cleaning purposes for example wherein a single sheet may unfold to become the side panels and roof, slotting together with such drip tray to form the device in use. The drip tray may comprise a base panel with elevated edges.

With such embodiments once side panels are screwed into place, the drip tray or base panel, and in some embodiments it may be envisaged a back plate, may be slotted into or over these panels to create a tight seal.

In some embodiments the device may comprise means to improve or alter the capabilities or characteristics of the oven in which it is used, for example Venturi, holes or airflow channels which may be critically placed to circulate air flow and to improve the cooking characteristics and browning of food products, or increased absorption, retention or reflection or refraction of heat within the oven.
