Definitions

• the present invention relates to a method for manufacturing a cardboard container.
• the aim of the invention is to solve the problem described above by providing a method for manufacturing a cardboard container that allows to simplify considerably the treatment steps, achieving formation of the finished container with a single operating step which can be performed on automatic machines.
• an object of the present invention is to provide a method in which it is possible to perform surface treatments in relief or in bas-relief, thus contributing to a further improvement of the aesthetic appearance.
• Another object of the present invention is to provide a method which, thanks to its particular constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
• Still another object of the present invention is to provide a method that can be obtained easily starting from commonly commercially available elements and materials and is also competitive from a merely economical standpoint.
• a method for manufacturing a cardboard container characterized in that it comprises the steps of: printing a coated face of a sheet-like cardboard element; die-cutting said sheet-like element in order to provide at least one monolithic element which has, on the free sides of the front wing and of the rear wing, folding flaps which are separated by scoring lines and have connecting tabs; applying an adhesive material to the inner face of said flaps that lies opposite said coated face; and forming the container by folding said flaps, superimposing them on said connecting tabs.
• Figure 1 is a schematic view of the sheet-like element made of single- coated cardboard, after performing the printing step;
• Figure 2 is a view of the monolithic element;
• Figure 3 is a view of the monolithic element taken from its inner face;
• Figure 4 is a schematic view of the initial step of the folding of the flaps;
• Figure 5 is a view of the folded flaps;
• Figure 6 is a schematic perspective view of the resulting container in the open position;
• Figure 7 is a perspective view of the container obtained in the closed position
• Figure 8 is a view of the application of reinforcement inserts inside the container.
• the method for manufacturing a cardboard container consists in printing, on a coated face of a sheet-like element 1 made of cardboard, which can be single- or double-coated, representations or in any case images that are deemed necessary.
• the step of die-cutting at least one individual element 10 monolithically is performed, together with the provision of the scoring lines that will facilitate formation.
• the element 10 defines in practice a front wing 11 and a rear wing 12, which are separated by means of a spine 13, which is delimited by spine scoring lines, designated by the reference numeral 14.
• first upper front flap 15 and a second upper front flap 16 which are separated by an upper scoring line 17, and a first lower front flap 18 and a second lower front flap 19, which are separated by a lower scoring line 20.
• the flaps 15, 16 and 18, 19 are arranged on mutually opposite edges, while a first lateral flap 21 and a second lateral flap 22 of the front wing are formed which are separated by a front scoring line 23.
• first upper rear flap 25 and a second upper rear flap 26 which are separated by an upper rear scoring line 27, and there are a first lower rear flap 28 and a second lower rear flap 29, which are separated by a lower rear scoring line 30.
• a first rear lateral flap 31 and a second rear lateral flap 32 are provided on the lateral edge and are separated by a lateral rear scoring line 33.
• the step of folding the flaps is performed by folding the first flaps onto the second flaps both at the front wing and at the rear wing, below and above.
• the tabs 40 are then folded and remain inserted and retained between the first and second lateral flaps, which are folded back. In this manner it is possible to provide, with a single operating step, the container, which is completely finished and is structured so that it can be opened in a clamshell fashion in order to facilitate access to its interior.
• the invention achieves the proposed aim and objects, and in particular the fact is stressed that a method is provided which, in a completely automatic manner, allows to provide a container which can be opened in a clamshell fashion and has an outer surface which is perfectly finished at the end of a single operating step for formation.
• the resulting product can be processed with portions shaped in relief or bas-relief and the product can be recycled easily, since it has no plasticization on its surface.
