Benefits of technology

[0013] It is a further aim of the invention to obtain a product of paper material of reduced costs by decreasing or eliminating the working rejects as much as possible.
[0014] It is a still further aim of the invention to obtain trays for containing foodstuffs that are of simple manufacture and require a limited number of manufacturing operations.

Problems solved by technology

Actually, these containers do not offer a satisfactory resistance against forces directed transversely of the side walls, which results in the risk that deformations due to handling of the container already filled with the foodstuff may cause escape of the product.
First of all the presence of glue and elements of different nature in engagement with each other can cause foodstuff contamination and also enable the humidity contained in the food to penetrate the paper fibres wetting them and therefore greatly lowering the resistance to stresses of same container.

Embodiment Construction

[0023] With reference to the drawings, a tray for containing foodstuffs has been generally identified with reference numeral 1.

[0024] The container is fully made of paper material starting from a flat sheet of the type shown in FIG. 1, as better clarified in the following.

[0025] In detail, the tray is intended for conservation and possible cooking of foodstuffs, such as prepackaged products for example.

[0026] As can be seen from the accompanying drawings, the tray has a flat bottom wall 2 from which a side wall 3 emerges that, in cooperation with said bottom wall 2, defines a holding space 6 set to receive the appropriate food.

[0027] While not essential, bottom 2 can be of a substantially rectangular shape the sides of which are connected with each other by short curved sections.

[0028] In this way the side wall 3 emerging from said bottom will show respective straight portions 4 emerging from the straight sections of bottom 2, alternated with curved portions 5 (defining the tra...

Abstract

A tray of sheet paper material for containing foodstuffs in which there is a bottom and a side wall emerging therefrom and defining, in cooperation with said bottom, a holding space facing upwardly under use conditions of the tray; the side wall is defined by alternated straight portions and curved portions both having upwardly-facing flat surfaces (7, 9) to allow engagement of a closing film heat-sealed thereto; the straight portions (4) also have reinforcing tabs in engagement at the lower part thereof with the flat surfaces (7) and the tray is also provided with a reinforcing edge (10) folded downwardly along the whole upper perimeter of the container itself. The tray thus made has excellent features of mechanical resistance to deformations.

Description

FIELD AND BACKGROUND OF THE INVENTION [0001] The present invention relates to a tray for containing foodstuffs and to the method of producing the same. In detail, the invention relates to a container of paper material intended for conservation and possible cooking of foods such as lasagne, prepackaged dishes, etc. [0002] It is known that there is on the market a great number of food containers made of paper material and adapted to allow conservation and / or cooking of products of different nature. [0003] Containers defined by a flat bottom wall of substantially rectangular shape from which a side wall emerges and is adapted to delimit, in cooperation with the bottom wall, a holding space set to receive the appropriate food are well known. [0004] Such a holding tray is then provided, at the upper part thereof, with an outwardly-bent edge capable of defining a continuous flat surface over the whole upper periphery of the container. [0005] The flat surface (with an extension parallel to...
