A PACKAGING, IN PARTICULAR OF A SECONDARY TYPE, FOR THE PACKAGING OF A PRODUCT.

Field of application of the present invention

The present invention relates to a packaging, in particular of a secondary type, for the packaging of a product.

State of the art

Secondary packagings are known, for the packaging of packages, especially primary packages, of a respective good or respective goods, which goods are preferentially goods of the so-called tissue industry in corresponding paper material and in particular in the form of rolls, in particular of toilet paper, kitchen paper, or wiping paper, large rolls, or other.

According to a known type, said secondary packagings comprise a casing in plastic film surrounding said packages or packs, in plastic film.

One problem related to this packaging is that it can nevertheless become harmful to the environment, in particular if improperly discarded to waste.

According to another known type, said secondary packagings comprise a large cardboard box, within which said packages or packs of rolls or other are placed.

However, the latter type of packaging is too heavy, excessively bulky, and results in excessive waste of paper material.

A further problem felt in both types of already-known packaging concerns the lack of airtightness. Air and any dirt can in fact enter the casing, though it is closed, through the small openings left by the less-than-perfect closing seals that are obtained in said plastic film, as well as substantially open are the cardboard packagings for the air passage that is left between one panel and another. All of this leads to a risk of contamination to the product contained within such packagings.

Summary of the invention

Therefore, by the present invention it is desired to propose a new, alternative solution to the solutions known so far, and in particular it is proposed to obviate one or more of the drawbacks or problems referred to above and/or to meet one or more of the needs referred to above, and/or however felt in the art, and in particular deducible from the above.

Therefore, a packaging is provided, in particular of a secondary type, for the packaging of a product, in particular said product being in the form of an article, preferably of a group of articles, preferably the article being in the form of a respective good and/or of a package, especially a primary package, of a respective good or respective goods, which goods are preferentially goods of the so-called tissue industry and/or are in corresponding paper material, i.e. , in thin sheet or ply of paper material, or they are non-woven fabric products, or sanitary napkins or diapers for personal hygiene, or in other material; in particular said goods being preferably in the form of rolls, in particular of toilet paper, kitchen paper, or wiping paper, large rolls, wipes, tissues, napkins, small clothes, bed sheets, or other, and/or said packages, or primary packagings of said goods, being in the form of packets, packs, envelopes consisting of a respective wrapping in plastic film or paper sheet, or other, or in the form of boxes, e.g., of paper board or cardboard, or in the form of another type of package; the packaging comprising a casing, surrounding said product, and is characterized in that said casing is in the form of an envelope made of paper.

In this manner, a robust and environmentally friendly packaging is achieved, i.e., in an advantageous, and also lightweight, material, i.e., such as to obviate an excessive waste of material. According to another aspect, a process is provided, to make a packaging, in particular of a secondary type, for the packaging of a product, in particular said product being in the form of an article, preferably of a group of articles, preferably the article being in the form of a respective good and/or of a package, especially a primary package, of a respective good or respective goods, which goods are preferentially goods of the so-called tissue industry and/or are in corresponding paper material, i.e. , in thin sheet or ply of paper material, or they are non-woven fabric products, or they are sanitary napkins or diapers for personal hygiene, or in other material; in particular said goods being preferably in the form of rolls, in particular of toilet paper, kitchen paper, or wiping paper, large rolls, wipes, tissues, napkins, small clothes, bed sheets, or other, and/or said packages, or primary packagings of said goods, being in the form of packets, packs, envelopes consisting of a respective wrapping in plastic film or paper sheet, or other, or in the form of boxes, e.g., of paper board or cardboard, i.e., in the form of another type of package; the process providing for the insertion of the product in a corresponding casing, and for the closure of said casing, containing the respective product, around the same product; characterized in that it uses a corresponding casing that is in the form of an envelope made of paper.

In this manner, a robust and environmentally friendly packaging is achieved, i.e., in an advantageous, and also lightweight, material, i.e., such as to obviate an excessive waste of material.

According to another aspect, an equipment is provided, to make a packaging, in particular of a secondary type, for the packaging of a product; in particular said product being in the form of an article, preferably of a group of articles, preferably the article being in the form of a respective good and/or of a package, especially a primary package, of a respective good or respective goods, which goods are preferentially goods of the so-called tissue industry and/or are in corresponding paper material, i.e., in thin sheet or ply of paper material, or they are non-woven fabric products, or they are sanitary napkins or diapers for personal hygiene, or in other material; in particular said goods being preferably in the form of rolls, in particular of toilet paper, kitchen paper, or wiping paper, large rolls, wipes, tissues, napkins, small clothes, bed sheets, or other, and/or said packages, or primary packagings of said goods, being in the form of packets, packs, envelopes consisting of a respective wrapping in plastic film or paper sheet, or other, or in the form of boxes, e.g., of paper board or cardboard, i.e. , in the form of another type of package; comprising means for the supply of said product, means for the insertion of the respective product in a corresponding casing; characterized in that said casing is in the form of an envelope made of paper.

In this manner, with advantage, a robust and environmentally friendly packaging is achieved, i.e., in an advantageous, and also lightweight, material, i.e., such as to obviate an excessive waste of material.
