The object of the present invention is also a case made by means of this method.
The present invention is further directed to a second die-cut paper material sheet to make an integrated holder, of the box-like type, for one or more writing tools, which can be coupled to a case according to the invention.

KNOWN PRIOR ART

Cases or agendas are known, which comprise a notebook of removable paper sheets, which is applied on an inner surface of the cover of the case or agenda, which in turn can provide for a housing intended to accommodate a pen or other writing tool.
For example, cases or agendas are known, which are made by means of a paper-making method in which, from a single die-cut sheet preferably of card stock, a support for a paper notebook is made to constitute e.g. a notepad which is equipped at the top or at a spine portion with a box-like prismatic compartment for a pen or other writing tool. Preferably prismatic, i.e. box-like, paper material holders, for housing a plurality of writing tools, e.g.
cases of markers, pencils or pastels, are also known.
These holders are made by means of a paper-making method, in which a single die-cut sheet, preferably made of card, is folded to form a holder with a housing portion and a closing portion, in order to allow the housing and holding of a plurality of writing tools arranged adjacent to each other.
The shape of the cases of the known art does not provide the housing of such a holder comprising a plurality of writing tools, e.g. a box of markers or pencils or pastels, and the simultaneous housing of a notebook.
It should be noted that here and hereinafter the expression "notebook" means a paper, or other suitable paper material, notebook bound on any side, e.g. by gluing, sealing, or ring binding or more, so that it can be flipped through by a user.
This paper notebook can be made up of white sheets or sheets equipped with traces for drawing and/or colouring. Object of the present invention is to implement a case with an integrated holder for a plurality of writing tools and a respective notebook, by making use, at least partially, of a paper-making method in a simple and economical way.
Another object of the invention is to implement a case with an integrated holder for at least one writing tool and with a notebook which, by using only paper material for the cover, the holder and the respective notebook, complies with the objectives of reducing pollution from plastic or synthetic materials.
It is still another object of the present invention to implement a case, with a book-like or notepad-like opening, equipped with a respective paper material support for the holder of writing tools, which allows to keep such holder in a raised position during use by a user, in order to assist access to the writing tools housed therein, and wherein said support can be easily obtained from a single paper material plate or sheet through a paper-making method.

DETAILED DESCRIPTION OF THE FIGURES

The present invention will now be described, by way of non-limiting example, with reference to the accompanying figures, in which it is possible to see, in addition to the case 1 which comprises a notebook 3 and an integrated holder 2 for one or more writing tools, such as pens, pencils, pastels, markers or more, and which is depicted both in the open configuration (figures 6, 7 and 8) and in the closed configuration, also a die-cut paper material sheet 10 intended to constitute the cover of case 1 according to an embodiment of the invention (figures 1A and 1B), a die-cut paper material sheet 20 intended to constitute the integrated holder 2 for at least one writing tool S, according to a further embodiment of the invention (figures 2A and 2B) and also some steps of folding such die-cut sheets 10, 20, operated during the method to make the case 1.

The cover of the case

The cover C of the case 1 according to a preferred aspect of the invention can be made by folding a die-cut sheet, here simply referred to as paper material "die-cut sheet", which is provided with first pre-set folding lines and which is globally denoted by the reference numeral 10 in figure 1 (as well as in the further accompanying figures) . The sheet 10 has a plurality of cover elements 101, 102, 103, 104 seamlessly joined together and mutually separated, i.e. geometrically separated, by the aforesaid corresponding first folding lines 11, 12, 13 parallel to each other.
The cover elements are preferably of square or rectangular, more generally quadrangular, shape and can be reversibly folded along the first parallel folding lines 11, 12, 13 between an open configuration and a closed configuration to form at least part of the cover of the case 1, in particular to form at least one front cover element 103, one back cover element 101 and one spine cover element 102.
In the present description, the term "folding lines", or also "creases", means dry traces made on the paper material sheets, e.g. card stock or cardboard, which make folding easier.
It should be noted that the cover elements 101, 102, 103 are here referred to as essentially quadrangular, since such is the shape by which such types of cases are commonly made. However, any other polygonal shape, even if not regular, that allows the making of a case 1 by means of the method illustrated here, can be used.
In the embodiment of the die-cut sheet 10 shown in figures 1A and 1B (in which the face of the sheet 10, which in the cover of the case 1 is intended to be external, is visible), a front cover element 103 and a back cover element 101 are separated from each other by a spine cover element 102 through two parallel folding lines 11, 12 belonging to the aforesaid first parallel folding lines 11, 12, 13.
The length of the elements 101, 102 and 103 determines the height of the case 1.
In the embodiment of the die-cut sheet 10 depicted in figures 1A and 1B, there is a further element 104 which is joined to the element 103 by a folding line 13 belonging to the first folding lines 11, 12, 13. As will be shown, this element 104 constitutes a reinforcing element of the element 103 to which it is joined by the folding line 13. As will be better explained below, the folding of the back, spine and front elements 101, 102, 103 of the sheet 10 and the folding of the reinforcing element 104, in such a way as to be superimposed on one face, the inner one, of the front element 103, allows to make the cover of the case 1. In a possible embodiment depicted in figure 1A, the die-cut sheet 10 can further comprise a plurality of panels 105, 106 mutually separated therein by corresponding second folding lines 14, 15 parallel to each other, which are arranged transversely to the first folding lines 11, 12, 13, where such plurality of panels 105, 106 is seamlessly connected to one of the front cover element or the back cover element 101, 103 which is placed in the end position of the sheet 10, i.e. in the free end position. In the embodiment of the sheet 10 shown in figure 1A, the panels 105, 106 are joined - in particular through the panel 105 - to the back cover element 101 through a folding line 14 belonging to the second folding lines 14, 15.
As will be more fully explained below, the folding of such panels 105, 106, in particular so that they take a "L" shape with the outermost panel 106, partially overlapping the notebook 3, allows to make a housing for a writing tool, such as a pen, a pencil, etc., or for a writing aid, such as a rubber, a paint, e.g. white covering paint (so-called "correcting fluid"), scissors, etc.
It should be noted that, according to a possible alternative implementation of the sheet 10 shown in figure 1B, such panels 105 and 106 which allow to make a housing for a writing tool, are not present.

The making of the case

According to a preferred aspect of the invention, the method for the making of the case 1 from the die-cut sheet 10 further provides for a step of constraining, preferably a fastening constraint, the at least one holder 2 for one or more writing tools S to the at least one die-cut sheet 10 at the front element 103 of the cover 1 or at the reinforcing element 104 folded in such a way as to be superimposed on the inner face of the front element 103. In particular, according to an embodiment of the invention, a back surface of the holder 2 is constrained, and preferably fastened, to an inner face of the front element 103 of the cover of the case 1 or at the surface of the reinforcing element 104 folded in such a way as to be superimposed on the inner face of the front element 103. In a preferred embodiment, the back surface of the holder 2 is constrained, and preferably fastened, at the surface of the reinforcing element 104 folded in such a way as to be superimposed on the inner face of the front element 103 by means of constraining means 104' arranged on the reinforcing element 104.
As will be better described below, such constraining means 104' (Figures 1A, 1B and 6B) comprise means adapted to make an interlock, e.g. a tab or a slot, with corresponding constraining means made on the holder 2.
According to a possible embodiment, the interlock between the constraining means made on the holder 2 and the constraining means 104' arranged on the inner face of the front element 103, or on the reinforcing element 104, can be made more stable and effective by means of an optional gluing.
However, embodiments are not excluded in which the back surface of the holder 2 is constrained, and preferably fastened, to an inner face of the front cover element 103 of the case 1 or at the surface of the reinforcing element 104 folded in such a way as to be superimposed on the inner face of the front element 103 exclusively by gluing. Although it has been provided here that the holder 2 for the writing tools S is directly, or as will also be shown indirectly, constrained to the front element 103 of the die-cut sheet 10, as the person skilled in the art will appreciate well, there is nothing to prevent the holder 2 from being alternatively constrained, directly or indirectly, to the back cover element 101.
It should be noted that in principle any holder, preferably of the reclosable box-like type, for one or more writing tools, e.g. pens, pencils, pastels, markers, etc., can be used for the making of the case 1 according to the present invention. However, as will be better discussed below, the holder 2 is preferably a box-like holder made from a die-cut paper material sheet 20 and comprises a holding portion 200 which preferably has a rectangular cross-section, in such a way as to be able to house a plurality of writing tools S, such as pens, pencils, pastels, markers, etc., positioned lined up inside the aforesaid holding portion 200.
As shown in figures 6A - 8, according to a preferred aspect of the invention, the holder 2 has a width substantially equal to or slightly lower than the width of the front cover element 103 to which it is connected and has a thickness that can be substantially equal to half the width of the spine cover element 102.
The method for the making of the case 1 according to the invention further provides for a step of constraining, preferably a fastening constraint (e.g. by gluing or through mechanical constraint with a metal spiral or by means of staples or more known to the person skilled in the art), at least one paper notebook 3, at the back cover element 101.
Generally, it is provided that a paper notebook 3 is directly or indirectly constrained to that back or front element 103, 101 of the cover 1 which is different from the front or back element 101, 103 at which the holder 2 is fastened.
As shown in figures 6A - 8, the notebook 3 has a width substantially equal to or lower than the width of the back cover element 101 to which it is connected and may have a thickness substantially equal to half the width of the spine cover element 102.
According to an aspect of the invention, the sum of the thickness of the holder 2 for the writing tools and of the paper notebook 3 is preferably equal to or less than the width measured orthogonally to the respective folding lines 11, 12 of the spine element 102, so as to allow the closed configuration of the case 1 to be properly reached. In an embodiment, where a die-cut sheet 10 without the reinforcing element 104 is used, a back surface of the holder 2 is fastened directly at an inner face of the front cover element 103 of the case 1 and a back surface of the notebook 3 is fastened at an inner face of the back cover element 101 of the case 1.
Next, the method according to the invention comprises a step of folding the plurality of cover elements 101, 102, 103 along such first folding lines 11, 12 in the closed configuration of the case 1.
In this closed configuration of the case shown in figure 8, the at least one holder 2 and the at least one paper notebook 3 face each other and are interposed between the front cover element 103 and the back cover element 101. In an open configuration of the case 1 shown in figure 7, the at least one holder 2 and the at least one paper notebook 3 are substantially aligned and lie substantially on the same plane defined by the inner face of the front cover element 103 and by the inner face of the back cover element 101 that are arranged coplanar to each other in the aforesaid open configuration by the user.
In a preferred embodiment of the case 1, the die-cut sheet 10 comprises, as stated and as shown in figure 1, at least one cover reinforcing element 104 placed in the end position of the sheet 10 and seamlessly connected to one of the front cover element 101 and the back cover element 103 thanks to a folding line 13 belonging to the first folding lines 11, 12, 13 parallel to each other.
In particular, as shown in the implementation of figures 1A and 1B, the cover reinforcing element 104 has a free end and an end seamlessly connected to the front cover element 103 thanks to the folding line 13 belonging to the first folding lines 11, 12, 13.
In an embodiment not shown here, the reinforcing element 104 can be connected to the back cover element 101 thanks to a folding line parallel to the first folding lines 11, 12, 13 or there may be two reinforcing elements arranged on the sides of the back element 101 and the front element 103, respectively, and separated therefrom by folding lines belonging to the first folding lines 11, 12, 13.
In a possible embodiment, before the step of constraining/fastening the at least one holder 2 at one of the front or back cover elements 103, 101, the method comprises the further step of folding the cover reinforcing element 104 on the front or back cover element 103, 101 to which it is connected, preferably by means of the constraining means 104' and optionally of gluing, so that the holder 2 is subsequently constrained/fastened to the cover reinforcing element 104, at the front or back element 103, 101.
In a preferred embodiment shown in figures 6A and 6B, the at least one reinforcing element 104 is connected to the front cover element 103 and is folded thereon.
This way, the holder 2 is connected to the cover reinforcing element 104 at the front cover element 103, so that the notebook 3 is connected to the back cover element 101. This configuration is generally preferable because the positioning of the notebook 3 at the back cover element 101 facilitates the writing operation (for a right-handed user) when the case 1 is in the open configuration.
It should be noted that, although it has been described so far the fact that the at least one holder 2 and the at least one notebook 3 are preferably fastened to the inner surfaces of the cover of the case 1, generally by gluing or through mechanical constraining means (such as spirals, staples, etc.), other forms of constraint, even reversible, are possible, such as e.g. the insertion of one or more projecting fins of such holder 2 or notebook 3 in slots or seats formed on the elements of the same cover of the case 1.
For example, a back surface of the holder 2 for the writing tools S can be fin-shaped, i.e. it can be equipped with a free end and have a portion that can be inserted in a notch formed in the reinforcing element 104. In this constraining mode, a gluing of the insertable portion of the back surface of the holder 2 to the same reinforcing element 104 may also be provided.
The cover elements 101, 102, 103, 104 of the die-cut sheet 10 are preferably four in number but as is clear to the person skilled in the art, for the making of a cover of such case 1, it is sufficient that their number be at least equal to three.
Embodiments are not excluded in which the die-cut sheet 10 comprises any number of the aforesaid elements, provided that they are higher than three, parallel to each other and preferably quadrangular and internally separated by first parallel folding lines, for the making of the cover of the case 1.
As already mentioned, in a particular embodiment shown in figure 1A, the die-cut sheet 10 comprises, as shown in figure 1, some panels 105, 106, e.g. quadrangular panels, which are joined to an element 101 or 103 of the sheet 10 through second folding lines 14, 15 perpendicular to the aforesaid first folding lines 11, 12, 13. More particularly, in the embodiment shown in figure 1A, a panel 105 is joined, through a folding line 14 orthogonal to the first folding lines 11, 12, 13, to the back cover element 101 which is intended to support the aforesaid paper notebook 3.
In this embodiment, the method therefore comprises the further step of folding the panels 105, 106 along the second folding lines 14, 15 in a closed configuration, so that the panels 105, 106 form at least part of a housing A of the case 1 adapted to house at least one additional writing tool S' or at least one writing aid.
Figures 6A, 6B and 7 show that the panels 105, 106 are folded along the second folding lines 14, 15 in such a way as to form a structure at least partially prismatic and especially at least "L"-shaped, and the method comprises the further step of making part of one of the panels 105, 106 adhere to the surface of the notebook 3 to fasten the "L" structure in position and thus make the aforementioned housing A.
As shown in figures 6A, 6B and 7, the notebook 3 is fastened to the respective back cover element 101, in such a way as to extend below the "L" structure formed by the panels 105, 106 and thus form a tubular holding structure, i.e. a housing A, between the notebook 3 and the "L" structure for at least one writing tool or aid.
Should the notebook 3 were fastened to the front cover element 103, then preferably also the panels 105, 106 would also be joined to such front element 103 to form the aforesaid housing A with the notebook 3.
Since the structure made with the panels 105, 106 is preferably "L"-shaped in order to form, with the notebook 3, a tubular holding structure having square or rectangular (or in any case polygonal) section with at least one end open to allow the insertion of a writing element, the number provided of panels 105, 106 is at least equal to two.
It is not excluded that this number may be higher.
It is therefore possible that the number of panels 105, 106 of the type referred above is sufficient to define, without cooperating with the paper notebook 3, an upper housing for a writing tool or aid, so that not necessarily the panels 105, 106 must be joined to the back or front element 101, 103 of the die-cut sheet 10 intended to support the notebook 3.
