OBJECT OF THE INVENTION
[0001] The invention, as stated in the title of this specification, refers to a cardboard cutlery implement that provides the function to which it is designed with advantages and characteristics, that are disclosed in detail thereafter, that mean an improvement of the current state-of-the art.
[0002] The object of this invention refers, concretely to a single-use cutlery implement, preferably a teaspoon that, mainly applicable for its use in the professional sector of ice-cream and restaurant industry, although others are not discarded, such as food product industry of canned and ready-to-eat products or that of household single-use cutlery, offer the advantage of being fully ecological as it is made of carboard, concretely out of a plurality of layers of carboard joined to each other and coated with a special layer of water-based flexographic ink that, in addition to a great strength and multiple printing possibilities of ornament and color, endows it with a bright finish that makes it impermeable and provides a smooth and soft surface , suitably pleasant for its use, similar to that of any metal or plastic cutlery implement.
FIELD OF APPLICATION OF THE INVENTION
[0003] The field of application of this invention is within the sector of industry engaged in the production of single-use utensils, namely focused in the scope of cutlery implements, for example spoons and teaspoons.
BACKGROUND OF THE INVENTION
[0004] As it is known, the use of single-use products that are not perfect and easily degradable is a growing serious problem to the environment because, thousands of them are daily used.
[0005] One example of them are the cutlery implements, for instance the teaspoons used in the sector of ice-cream industry to accompany the sale of ice-creams, or in the sector of the restaurant industry in general, to stir coffees and every type of beverages, as well as in the sector of food product industry that, is commercializing, every time with a growing volume, any type of packages for ready-to-eat food to which the cutlery implements are accompanied, that use to be made of plastic material.
[0006] The objective of this invention is, therefore, to provide another alternative to the said type of cutlery implements by means of developing a new product that, while offering the same benefits as the plastic cutlery implements, is fully ecological, being to that purpose made of cardboard, for which the problem of using the said material has been technically overcome in a product that, for its use, has to be mechanically resistant to a certain level of force exerted on it and, above all, structurally to the humidity, because in many cases it shall serve to be introduced in liquids and anyway it shall have to stand the humidity of the mouth of the user.
[0007] On the other hand, and as reference to the current state-of-the-art, it shall be pointed out that, at least the applicant is not aware of the existence of any other cardboard cutlery implement or any other invention having a similar application, that possesses technical, structural and constitutive features equal or similar to those that the one herein claimed possesses.
EXPLANATION OF THE INVENTION
[0008] The cardboard cutlery implement that the invention proposes is configured as the suitable solution to the above-mentioned objective, the characterizing details that make it possible and that distinguish it conveniently appears in the final claims attached to this description.
[0009] More concretely, what the invention proposes, is a single-use cutlery implement, preferably a teaspoon that, mainly designed to its use in the professional sector of ice-cream and restaurant industry, without the food product industry of canned and ready-to-eat foods or within the household scope is discarded, is a fully ecological, compostable and bio-sustainable product as it is made of cardboard.
[0010] To that purpose, the said teaspoon is made out of a body composed of a plurality of layers of carboard joined to each other and coated as a whole with a special layer of water-based flexographic ink for food use, that means, applicable by means of a flexographic printing system , which provides the teaspoon or cutlery implement involved with the resistance required to pressure and humidity making its use possible.
[0011] Preferably, the cutlery implement, that in the preferred embodiment is a teaspoon, is formed out of 9 layers of cardboard providing it a total weight of 980gr/m2. The said layers are joined to each other with water-based food glue. And the whole assembly is coated with a layer of flexographic ink that, preferably is the Aquapak® brand commercialized by the Flint company, consisting in a system of water-based high resistant flexographic ink designed for its application as a coating treatment of polyethylene on cardboard, providing a highly bright finish, large printing capacity and high blocking resistance, as well as the maximum capacity of chemical and product resistance required for its use in products such as milk, juice and ice-cream.
[0012] Preferably, the teaspoon is formed by a single piece, the perimetral shape of which defines the head and the handle, it can have different sizes and shapes, as well as being fully flat, best fitted for its use with ice-creams, or curved-concave shaped, similar to the conventional soup spoons or teaspoons.
[0013] Anyway, the said composition of the cutlery implement, with the said layers of cardboard and the coating of the described flexographic ink, in addition to high resistance and multiple possibilities of printing ornament and color, endows it with a bright finish that, in addition to the impermeability provides a smooth and soft surface, suitably pleasant to be used, as it is similar to the surface that the any other metal or plastic cutlery implement possesses.
DESCRIPTION OF THE DRAWINGS
[0014] To complement the description that is being made and in order to assist to best understanding the characteristics of the invention, attached to this specification, as an integral part thereof, there are some drawings in which, for illustration and no limitation purpose, the following has been represented:
The figures numbers 1 and 2.- They show elevation front and side views, respectively, of a first example of the cardboard cutlery implement object of the invention, concretely a fully flat teaspoon;
the figures numbers 3 and 4.- They also show, in front and side view, respectively, another example of the cutlery implement of the invention, in this case a teaspoon having an angled head; and
the figure number 5.- It shows an enlarged view of a sectioned portion of the cardboard cutlery implement, according to the invention, showing the layers and elements of which, it is made.
