Definitions

• This invention relates to a food container, in particular for storing ice cream sorbets, cassata, spumone, semifreddo and the like and its production method.
• the containers which allow a better thermal insulation for a relatively long period of time are made of synthetic materials, for example plastic.
• the aim of the invention is to overcome the above-mentioned drawbacks in known types of food containers, in particular for storing ice cream, made of an eco-compatible material but which allows a good preservation of the food for a long time in hot environments.
• an aim of the invention is to provide a food container, in particular for storing ice cream, which is made in such a way as to have a low environmental impact.
• Another aim of the invention is to guarantee a high standard of hygiene.
• Another aim of the container according to this invention is to allow the product to be reused, at least partly.
• Yet another aim of the invention is to make a food container, in particular for storing ice cream, with prior art machines and means and using materials of common use, in such a way that the container is economically competitive.
• this invention relates to a food container, in particular for storing ice cream, comprising a tray which can be coupled with a respective lid and which has an inner tray for collecting the food product to be contained and designed to be associated with an outer case supporting the tray.
• the case has, on at least one upper edge of it, a supporting frame for a flap projecting from a respective face of the tray, in such a way that the thickness of the frame determines a predetermined distance between the innermost surface of the case and the outermost surface of the tray.
• upper refers to the position of an element, for example the edge of the case, with respect to the supporting surface of the tray.
• the terms “inner” and “outer” also refer to the chamber for collection of the ice cream, defined by the walls of the tray itself. An element is therefore “inner” or “outer” which faces, respectively, towards or away from the collection chamber.
• the Applicant has advantageously made a sort of air cushion between the tray for collecting the ice cream and the case of the tray which does not allow a direct exchange of heat, that is to say, by contact, between the wall in contact with the food product and the part in contact with the outside environment.
• the Applicant has also perceived that the possibility of making snap fitting means, between the tray and the case, by means of a system of foldable flaps which offers a triple advantage.
• connection would make the detachment from the inner tray of the outer tray more usable, facilitating the separation of the possible reusable part from the disposable part.
• the folding of the flaps on themselves to make the coupling allows the formation of a channel for collecting the liquids from dripping of the ice cream which inevitably are formed during the picking up of the food product with the spoon.
• Another aspect of the invention relates to the protection of a blank (or a pattern of the blank, if referred to its drawing) of the container, in particular of the tray.
• the Applicant has devised a blank (or the pattern of a blank) for a case for the food container, in particular for storing ice cream, which has a quadrangular bottom, from which protrude two front walls, opposite one another, and two side walls, also opposite one another, of the case to be made, wherein the front and side walls have at their ends an upper side which can be folded.
• the upper side connected to the front walls comprises a male element designed to be inserted in a slot of the tray and the upper side connected to the side walls is provided with a foldable flap and having a portion designed to be associated with the inner surface of the respective side wall.
• the blank comprises a bottom and a strip, located on two opposite ends, but designed to be associated with each other; the bottom is connected to a side wall formed by two mutually foldable parts, in such a way as to allow a substantially flat arrangement of the blank once the bottom and the strip are associated with each other.
• the edge of the tray can be spread, in such a way as to allow a better dosing of the ice cream.
• the edge of the tray can be spread, in such a way as to allow a better dosing of the ice cream.
• the folding of the above-mentioned flaps is very opportune.
• the lid must also perform as well as possible in line with the performance levels planned for the tray.
• joints can be provided which can allow the making of an inner layer and an outer layer which have a distance such as to form an air cushion similar to that described for the tray/case system.

• the flap 33 (133) is associated with each of the upper ends of at least two opposite faces of the tray 3 (103) (the so-called “short” sides of the tray), whilst each of the opposite faces (“long” sides) defines the frame 5 (105).

• the tray 3 (103) is associated with the case 4 (104) in a removable fashion.
• the user can in effect easily connect and disconnect the tray 3 (103) from the case 4 (104), without adversely affecting any of the components, withdrawing the teeth 42 from the respective slots 32 (132) for pulling the tray 3 (103) out of the case 4
• gluing is also possible.
• the case 4 (104) is made of recyclable material, for example melamine resin, a material which can also be washed in a dishwasher, whilst the tray 3 (103) is made of single-use paper.
• the user can re-use the case 4 (104), after having carefully washed it also in a dishwasher, disposing of the tray 3 (103) in the differentiated waste, in such a way as to guarantee maximum hygiene, thus eliminating the risk of salmonella, and with a minimum impact on the environment.
• the tray 3 (103) can also glued on the case 4 (104) by means of clips (not illustrated) advancing above the upper edges 31 (131 ) of the tray 3 (103) and resting on the frame 5 (105): precisely the clips/frame 5
• the lid 7 has an inner layer 71 and an outer layer 72 interconnected by engagement means of the male 71a and female 72a type, in such a way that the inner layer 71 comprises a tab 71 b for abutting on the innermost surface of the outer layer 71 .
