Inside leaflet of book

An inside leaflet of a book is provided which is bond-bound with pages of the book to provide an advertisement. The inside leaflet includes an advertisement printed part and a binding part. Catchphrases or illustrations for advertisement are printed on at least one side of the advertisement printed part. The binding part is configured to be bound with the pages along an edge of the inside leaflet such that the binding part has less binding portions than those of the pages in order to leave no traces or marks when the inside leaflet is detached from the book. Accordingly, since the inside leaflet is able to be bound to pages of various kinds of books and easily removed from the books without leaving any traces or marks in the books, the inside leaflet contributes to extension of the application range of advertisements and improvement of advertisement efficiency.

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. §119(a) of Korean Patent Applications No. 10-2010-0004654, filed on Jan. 19, 2010, and No. 10-2010-0040988, filed on Apr. 30, 2010, the entire disclosure of each of which is incorporated herein by reference for all purposes.

BACKGROUND

The following description relates to an inside leaflet of a book, which is bound with pages of the book to provide an advertisement.

2. Description of the Related Art

A leaflet is a paper based advertisement on which catchphrases or illustrations for advertisement are printed. Leaflets may be distributed in sheets or together with printings such as newspapers by being inserting therein. For example, a leaflet may be bond-bound with pages of a magazine, such as a monthly magazine or a daily magazine, and distributed together with the magazine. Such an inside leaflet included in a magazine may be detached from the magazine to be used or discarded. When the inside leaflet is detached from the magazine, the inside leaflet may remain certain traces or marks on the corresponding page of the magazine since the inside leaflet has been bond-bound with the pages of the magazine.

In order to eliminate the problem, a method has been proposed which makes a perforated line on a leaflet to cleanly detach the leaflet from a magazine along the perforated line. However, in this case, the page from which the leaflet has been detached will still remain in the magazine, and if the magazine is a valuable magazine, such a remaining page portion may cause readers to be unsatisfied.

As such, since conventional inside leaflets have a problem, there is limitation in applying such conventional inside leaflets to books, such as novels, examination books, reference books and the like, which tend to be kept for a long time. There is the case where a reader who bought a book, such as a novel, an examination book or a reference book, in which an inside leaflet has been bond-bound, removes the inside leaflet on determining that the leaflet is not needed.

In this case, since the inside leaflet has been bond-bound with pages of the book, the removal of the inside leaflet from the corresponding page will remain certain traces or marks on the page. For this reason, customers may be put off buying books including inside leaflets, and readers may be reluctant to view advertisements inside books. Consequently, due to the problem, the application range of inside leaflets may be limited and advertisement efficiency may be lowered.

SUMMARY

The following description relates to an inside leaflet of a book, which is bound with pages of various kinds of books and can be removed from the books without leaving any traces or marks in the books, thereby capable of extending the application range of advertisement and raising advertisement efficiency.

In one general aspect, there is provided an inside leaflet of a book, which is bond-bound with pages of the book to provide an advertisement, the inside leaflet including: an advertisement printed part having printed on one side a catchphrase or an illustration for advertisement; and a binding part configured to be bound with the pages along an edge of the inside leaflet such that the binding part has less binding portions than those of the pages in order to leave no traces or marks when the inside leaflet is detached from the book.

Therefore, even when the inside leaflet is bond-bound to a page of a book, the inside leaflet may be cleanly removed from the page without leaving any traces or marks on the page. Accordingly, the inside leaflet can be inserted into various kinds of books including magazines, without lowering customers' interest and causing a reluctance against inside advertisement of books. Furthermore, the inside leaflet does not deteriorate the possession value of a book. Consequently, the inside leaflet contributes to extension of the application range of leaflets and improvement of advertisement efficiency.

DETAILED DESCRIPTION

FIG. 1is an exploded, perspective view for explaining an example where an inside leaflet100according to an example is applied to a book, andFIG. 2is an enlarged view of an area A illustrated inFIG. 1.FIG. 3is a cross-sectional view of a book10into which the inside leaflet100and pages13illustrated inFIG. 1are bond-bound, andFIG. 4is a plane view of the is inside leaflet100illustrated inFIG. 1.

Referring toFIGS. 1 through 4, the book10to which the inside leaflet100is applied may be a novel, an examination book, a reference book or the like that tend to be kept for a long time. The book10is composed of a front cover11, a back cover12, pages12containing content of the book10and a backbone14. The pages13of the book10are arranged between the front cover11and the back cover12and bond-bound with the front and back covers11and12against the backbone14.

The inside leaflet100is bond-bound with the pages13of the book10to provide an advertisement to a reader who read the book10. That is, when a reader reads the book10, the inside leaflet100inserted between the pages13is exposed to the reader, thereby providing an advertisement effect. The inside leaflet100includes an advertisement printed part110having printed on at least one side catchphrases or illustrations for advertisement, and a binding part120configured to be bound with the pages12along an edge of the inside leaflet110. The inside leaflet100may be the same size as the pages13or a size smaller than the pages13.

The binding part120is formed to have less binding portions than those of the pages13bound against the backbone14, so as not to leave certain traces or marks when a reader detaches the inside leaflet100from the book100after viewing the inside leaflet100. Meanwhile, a conventional binding method in which a binding part of an inside leaflet has the same binding portion as other pages may leave certain traces or marks inside a book when the inside leaflet is removed from the book.

However, if the binding portions of the binding part120of the inside leaflet100are formed to be smaller than those of the other pages13in order to leave no traces or marks when the inside leaflet100is removed from the book10, portions at which the inside leaflet100is bonded with the pages13are also reduced so that the inside leaflet100can be clearly removed from the book10without remaining any traces or marks in the book10. Accordingly, the is inside leaflet100can be inserted into pages of various kinds of books as well as magazines, neither deteriorating customers' interest nor causing a reluctance against inside advertisements of books. In addition, the value of the book10can also be maintained. Consequently, the inside leaflet100contributes to extension of the application range of leaflets and improvement of advertisement efficiency.

Meanwhile, the binding part120may be formed with an arbitrary shape as long as it can be easily removed from the book10without remaining any traces or marks in the book10. For example, the binding part120may include grooves121that are formed with the same shape and cut out at regular intervals along an edge of the inside leaflet110. Different shapes may also be employed. Accordingly, portions at which the inside leaflet100is bonded with the pages13are aligned at regular intervals so that no traces or marks remain when the inside leaflet100is detached from the book10.

In order to further improve the effect for easy detachment without making any traces or marks, the width W1(hereinafter, referred to as an end width W1) between grooves121may be formed to be narrower than the width W2(hereinafter, referred to as an opening width W2) of each groove121. Specifically, a ratio W1/W2of the end width W1to the opening width W2may be set to 0.2 to 0.3. For example, the opening width W2of each groove121may be set to 8 mm and the end width W1between the grooves121may be set to 2 mm. In addition, each groove121may have a semicircle shape.

As another example, as illustrated inFIG. 5, grooves221each having a trapezoid shape may be formed. The example of a trapezoid is not intended to be limiting, and other shapes are contemplated. In other words, like the grooves121and221, the shape of grooves to be formed in an inside leaflet may be various as long as the inside leaflet leaves no traces or marks when being removed from a book.

Meanwhile, a notice for helping a reader detach the binding part120from the pages13is printed on the advertisement printed part110so that the reader can easily remove the inside leaflet100from the book10.
