Description

Protection for books and notebooks Technical area

The invention relates to a protection for books and notebooks. State of the art

[0002] When school starts, parents are often faced with the task of protecting the books and notebooks of their school children. This task must often be carried out in a relatively short time but with a good quality of execution.

A state of the art is a notebook / book cover comprising a plastic sheet provided with two flaps each defining an opening. The notebook / notebook cover is held in place by inserting the ends of the paper / notebook cover into the openings of the flaps. This state of the art demonstrates poor retention of the notebook / book cover when the book or notebook is in use.

Another state of the art is a non-adhesive plastic sheet positioned around the book or notebook with which flaps are formed and fixed between them and / or fixed on the inside of the cover pages, so as to ensure keeping the protective sheet around the book or notebook. This state of the art requires a long and laborious implementation and has a durability in use which is uncertain.

Another state of the art is a plastic sheet fully adhesive on one side, most often transparent, positioned around the cover of the book or notebook and comprising after cutting, flaps on the internal faces of the cover so to prevent peeling of the adhesive sheet from the edges of the book cover. This state of the art requires precise cutting and laborious implementation in order to avoid leaving air bubbles between the book cover and the adhesive sheet when it is placed.

Summary of the invention

[0006] According to a first aspect, one of the aims of the present invention is to provide protection for a book or for a notebook combining ease of use, speed of installation and good durability.

[0007] To this end, the inventor proposes protection for a book or notebook comprising: a first flap and a second essentially rectangular protection flap and connected by a protective back; - said first and second protective flaps each being delimited by: o said protective back, o An upper flap for maintaining the first and second flap respectively, o A lower flap for maintaining the first and second flap respectively, o A side flap of maintaining first and second shutter respectively; said protective back and said first and second protective flaps are non-adhesive; said top flaps, bottom flaps, and side flaps comprise a coating of an adhesive to allow adhesion between said retaining flaps and a cover of a book or notebook.

[0008] Thanks to the adhesive flaps delimiting the non-adhesive protective flaps, the fitting of the protection is relatively easy because it consists in bringing the adhesive coating of the flaps into contact with the second and third cover of a book or notebook. Thus, the protection according to the invention allows rapid installation and has good durability.

The advantage of the invention compared to adhesive protections entirely on one side is to allow easy positioning of the protective flaps on the first and the back cover. In the case of adhesive protectors entirely on one side, the positioning of the protective flaps is often a source of problems due to the formation of air bubbles or folds. Such air bubbles or folds are then visible when the book is closed. With the protection of the invention, it is possible to overcome this problem of air bubbles or creases by providing non-adhesive protective flaps and backing on both sides.

An advantage over a notebook cover of the state of the art provided with two flaps each defining an opening, is to have a protection which is better maintained on the book or the notebook because it does not risk slipping cover pages when opening the book. An advantage over a non-adhesive plastic sheet positioned around the book or notebook with which flaps are formed and fixed between them and / or fixed on the inside of the cover pages is that it is easier and faster. to position and that it does not require any folding other than folding allowing the flaps to wrap around the edges of the cover to reach the inside of the cover (second and third cover). In addition, the pre-cut protection provides better durability because the attachment of a non-adhesive plastic sheet positioned around the book or notebook with which flaps are formed and fixed between them and / or fixed on the inside of the pages. cover is often produced by adding adhesive tape having lower mechanical properties than those of the flaps and flaps of the protection according to the invention.

[0011] For example, the pre-cut protection can be placed in less than two minutes by a person uninitiated to cover books or notebooks. The pre-cut guard of the invention for placement does not require the use of a pair of scissors or any other cutting means. The pre-cut protection allows to generate less waste because it does not generate unusable scraps.

Preferably, the protection is a precut protection for a book and / or a notebook. A pre-cut protection eliminates the need for a cutting step, so as to save the time associated with cutting and to avoid the risk of a bad cutting of a protective sheet (adhesive or non-adhesive entirely on a sheet). face).

[0013] Preferably, said retaining flaps are configured to allow adhesion with a second and a third cover of a book or a notebook.

Preferably, the angle a is an angle between 80 ° and 90 °, more preferably, the angle a is a right angle.

The advantage of having an angle of between 80 ° and 90 ° and more preferably that it is straight, makes it possible to have better adaptability of the flaps to the thickness of the book or the notebook (of the object to be protected). In general, the inventor has noticed that the closer the angle α is to 90 °, the easier it is to adapt the present invention to varying thicknesses of a book or a notebook.

[0031] Preferably, it further comprises opposite each of said coatings (40) of adhesives, a peelable storage strip.

[0032] The adhesive coatings of the retaining flaps are covered by a peelable storage tape, a peelable storage tape is also known as a peelable protective tape. A peelable storage strip is for example made of silicone paper. A silicone paper is a paper on which at least one side is coated with a silicone coating. A silicone coating is a coating on which the adhesive coated on the retaining flaps adheres with a low force so that this strip constitutes the protection that is removed when putting the protection on the book or notebook that we want to protect. So when storing the protection

© BE2019 / 5711 Before use, the areas coated with adhesive on the retaining flaps do not accidentally stick to another part of the protection or to another object. This allows easier storage of the protections according to the invention. The peelable bands each form a separate band. Each peelable strip of each flap is removed as each flap is glued. This is particularly advantageous in comparison with the state of the art comprising a fully adhesive plastic sheet on one side for which a peelable sheet constituting a single piece must be removed in its entirety before the placement of the fully adhesive plastic sheet.
