FIELD OF THE INVENTION
The paper industry is a field in which a flat sheet of cardboard or paperboard is treated by die-cutting, creasing and folding in order to obtain a common use object, a box, a food container, a toy of simple or complex shape.
STATE OF THE ART
The applicant does not know a pen holder notebook substantially achieved by a papermaking process and presenting the invented features.
There are known notebooks simply formed of by a detachable sheets block applied on a carrier of cardboard laterally bearing an area intended to accommodate a pen, the term pen standing for a pencil, a ballpoint pen, a fountain pen. There are also known note books comprising a cover element fixed, generally, on their left side.
OBJECT OF THE INVENTION
The object of the invention is to produce at a considerably low cost an object that provides immediate and convenient the possibility of writing.
BACKGROUND OF THE INVENTION
While in the following of the present description the term “cardboard” stands for cardboard or paperboard, the use of one or other in the method depends on the size and quality that the manufacturer want to give the product.
The method comprises the steps of:
- A) Die-cutting and creasing of a cardboard sheet to obtain a single element comprising an assembly of parts suitable for receiving a detachable sheets block and hold a conventional pen, where the assembly of parts is:
a—a first rectangular or square element in part intended for the application of the detachable sheets block,
b—a second rectangular element on a first side of the first element and of a width equal to the thickness of the detachable sheets block,
c—a third rectangular or square element on the adjacent side of the second element and intended as notebook cover,
d—a fourth rectangular element on a second side of the first element of width equal to the thickness of the detachable sheets block, and
e—a fifth rectangular element, contiguous to the fourth element and of height suitable for covering the head of the detachable sheets block.
B) Apply the detachable sheets block on the bottom surface of the first element,
C) Fold the above elements along the creasings to get a notebook that includes a pen within a chamber at the upper end or at a side of the block.
The produced notebook is compact, complete with the detachable sheets block, the cover and the pen.
ADVANTAGES OF THE INVENTION
The process is very fast and the structure of the product allows a user to carry a notebook with the pen readily available.
EXAMPLE OF THE INVENTION
The invention will now be described in detail with examples of embodiment and the help of the drawing in which:
FIG. 1 is a first plan view,
FIGS. 2-8 are perspective views.
A first alternative shows the position of a ballpoint pen on the upper end of the block:
FIG. 1 shows the assembly of parts formed by die-cutting and creasing of a cardboard sheet S which defines a first rectangular element 1 having a height of 16.3 cm and a width of 10.5 cm intended for the application of a detachable sheets block having a height of 14.8 cm and a width of 10.5 cm; a second rectangular element 2 on a first side of the first element 1 and of a width equal to the thickness of the detachable sheets block equal to 1.0 cm; a third rectangular element 3 on the adjacent side of the second element 2 and intended to cover the notebook in production; a fourth rectangular element 4 on a second side of the first element 1, of width equal to the thickness of the detachable sheets block; a fifth rectangular element 5, contiguous to the fourth element and of height suitable for covering the head of the detachable sheets block; the L lines separating these parts and carrying the crease lines which allow to bend the die-cut elements and where the fourth rectangular element 4 has a length lower than the width of the fifth element to leave visible and accessible the pen.
FIG. 2 shows a ballpoint pen 6 placed on top of the first element 1. It is understood that, once the element 4 is folded in perpendicular position with respect to the first element 1 and the element 5 is folded parallel to the element 1, a chamber is obtained adapted to receive the pen, the chamber having a window 7 created by the reduced length of the element 4 to make visible and accessible one end of the pen.
FIG. 3 shows a detachable sheets block 9, of 1.0 cm thickness, crimped to lower part of the first rectangular element 1, the fourth rectangular element 4 of 1.0 cm height covers the head 9a and the detachable sheets block 9, the window 7 created in the rectangular element 4 and the rectangular chamber 8 adapted to receive a pen, not shown.
FIG. 4 shows a notebook finished where 4 indicates the rectangular element with its window 7 in which the clip 6a appears of a pen hidden in the chamber 8 created within the elements 1, 4, and 5.
A second alternative shows the position of a ballpoint pen 60 on one side of the block:
FIG. 5 shows a cardboard sheet S1 which defines a first rectangular element 10 intended for the application of a detachable sheets block; a second rectangular element 20 on a first side of the first element 10 and of a width equal to the thickness of the detachable sheets block equal to 1.0 cm; a third rectangular element 30 on the adjacent side of the second element 20 and intended to cover the notebook in production; a fourth rectangular element 40 on a second side of the first element 10, of width equal to the thickness of the detachable sheets block; a fifth rectangular element 50, contiguous to the fourth element and of height suitable for covering the side of the detachable sheets block; the two parallel L1 lines separating these parts and carrying the crease lines which allow to bend the die-cut elements and where the fourth rectangular element 40 has a length lower than the width of the fifth element to leave visible and accessible the pen.
FIG. 6 shows a ballpoint pen 60 lying on the element 40 defined between the elements 10 and 50.
FIG. 7 shows the element 50 overturned on the element 10 to define the chamber where the ballpoint pen is held.
FIG. 8 shows the element 30 overturned to cover the block. Also the outer side of the element 40 and the pen clip 6b are visible.
