Abstract

The invention relates to a paper material constructed from a plurality of layers and intended for baking moulds. The layers comprise, from the interior of the mould outwards: a water-repellent layer (3), a greaseproof paper (4), a grease-repellent layer (5), and a greaseproof paper (6).

Description

Paper material comprising a plurality of layers and intended for producing moulds for baking purposes.
The present invention relates to paper material constructed from a plurality of layers for producing baking moulds.
The per se well-known demands which are to be placed on a baking mould material and which are satisfied by the material according to the present invention are that:
1. the material should have the necessary degree of rigidity to withstand baking procedures, including mechanical handling of the moulds, baking and after-handling, without being deformed;
2. the material should withstand subsequent deep-freezing;
3. the material should be grease and water-repellent (proof) without looking soiled;
4. it should be easy to separate the mould from the pastry;
5. the material should withstand re-heating in a conventional oven or microwave oven and, at the same time, also satisfy points 2 - 4 above;
6. the material should be approved for foodstuffs; 7. the material should be part of a natural cycle, i.e. be compostable or, if burnt, should not pollute the air to a greater degree than when wood is burnt.
EP 544 973 Al discloses a container for preparing and distributing pastry or food. This container comprises a small paper vessel which withstands introduction into an oven and which has an upper flange which is folded in such a way that it forms a peripheral engagement groove for a support of a rigid paper material, which support has a through-aperture by means of which the vessel can be arranged so that the edge of the aperture engages the engagement groove. The vessel consists of an inner and an outer cup between which, at the base, there is an inlaid plate. The outer cup is produced from a heat and moisture- resistant paper material whilst the inner cup is produced from a moisture and grease-resistant paper material.
US-PS 2162764 concerns a container for lubricating oils and the like. It, therefore, has to be oil and grease-resistant but, moreover, has to have a cheap and simple construction which is also simple to destroy after use, such that it cannot be re-used. The specification states that the material of such a container comprises a number of bonded-together paper layers and a sealing material.
Moulds of the generally known type for so-called covered pastry, for example mazarines and pies, are made of aluminium foil. However, aluminium foil is a material which consumes a large amount of resources and, moreover, pollutes the environment, since its degradation time is long. A further disadvantage of baking moulds made of aluminium foil is that it is not possible to use a metal detector to detect metal objects which the pastry may accidentally contain. Yet another disadvantage of aluminium foil moulds is that they have to be removed carefully before any pastry which has exceeded its use-by date can be used as animal fodder.
The object of the present invention is to provide a paper material for baking moulds of the initially mentioned type which is economical to produce in terms of resources and is co postable. It should be possible to burn the material without the release of heat and thereby only pollute the environment to a slight degree.
In accordance with the invention, the mould material is constructed from a plurality of layers which, from the interior of the mould outwards, comprise: a water-repellent layer, a greaseproof paper, a grease-repellent layer, and a greaseproof paper.
Further advantages and notable features of the invention will emerge from the following description given-with reference to the appended drawings in which: Figure 1 shows as an example in plan view from above an oval embodiment of a mould made of the material according to the invention;
Figure 2 shows a section along the longitudinal axis of the mould in Figure 1; and
Figure 3 shows a cross-section through the mould material according to the invention.
The mould is provided, by pressing, with a plane base 1 and inclined sides 2 which are integral with the base and extend obliquely outwards. In accordance with the invention, the mould is made of a paper material which is constructed in layers which, from the interior of the mould outwards, comprise: a water-repellent layer 3, a greaseproof paper 4, a grease-repellent layer 5, and a greaseproof paper 6.
Externally of the outermost greaseproof paper there is advantageously a decorative layer 7. The sides 2 of the mould are substantially smooth; any irregularities therein result from the starting material's being folded double at random during the pressing process. The sides 2 terminate at the top in a projecting flange 2a which forms an angle with the sides 2, preferably such that it is substantially parallel with the base 1. The flange 2a is formed with an indentation 2al which forms a groove extending along the flange 2a. Preferably, but not necessarily, the indentation is produced from below, i.e. the flange 2a has on its upper side an annular ridge 2a2 of which the cross-section is substantially semi-circular.
The indentation 2al contributes decisively to the stability of the mould and enables it to withstand the stresses which occur when paste is pressed into the mould.
In conclusion, it can be noted that the mould material according to the invention provides a baking mould which satisfies the demands listed at the beginning in points 1 to 7. The layer 3 helps to satisfy point 4, namely that it should be easy to separate the mould from the pastry, this layer 3, according to a particular feature of the invention, being a layer of lacquer applied to the greaseproof paper layer 4.
As emerges from a further particular feature of the invention, the layer 5, which is a layer of adhesive, has the dual task of firstly holding together the greaseproof paper layers 4, 6 and secondly of forming a grease-repellent layer which, together with the layer 6, satisfies the requirement of point 3.
