Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a book with a book cover, and more particularly to a book with a book cover capable of confirming unopening and suppressing browsing.

[0002]

2. Description of the Related Art Generally, when a book is issued by a publisher, the distribution channel of the book is sold as a new book at a bookstore, passed to a used book dealer by a consumer who has purchased the book, and further used as a used book. It will be distributed to the market again.

However, in the above-mentioned distribution channel,
There are various problems. A first problem is that, for example, a book sold at a store has a low commercial value due to the end of the page being bent or the cover being damaged due to browsing or the like. There are many.

[0004] Under such circumstances, manga books issued at a pace of, for example, monthly or bimonthly in a series are particularly likely to be browsed. Therefore, depending on the store, bags or cords may be used to prevent damage or stains. To make new packaging, and to wrap and wrap the book itself in a transparent material such as cellophane or vinyl.

[0005] However, in any case, the above-described browsing prevention processing involves further wrapping on a book, and is also performed manually for each book. Therefore, there is a problem that time, material, and manpower are required for the processing.

As a second problem, the expansion of the used book market has recently been taken up as a major problem in the publishing industry. For example, depending on the used book dealer, even though it is a used book, the end of the discolored page may be scraped off using a grinder, etc. After the reproduction process is performed by wiping it off, there is a case where it is displayed at a store and sold as if it is a new book. For this reason, a serious problem such as a decline in sales of new books has arisen. Since the book subjected to the reproduction processing is beautiful in appearance, it is very difficult for the purchaser to determine whether the book is a new book or an old book.

To solve the first and second problems described above, Japanese Patent Application No. 11-109545 and Japanese Patent Application No. 11-115 filed earlier by the present applicant have been proposed.
There is 552 "Book with book cover".

[0008] In these "books with book covers", most of the books currently on the market are printed on a printing surface (P) in view of durability, aesthetics, and damage resistance.
A book cover that has been subjected to surface gloss processing (front side) such as P coating) or press coating (applying acrylic paint and mirror finishing) is used.

One of the folded portions of the book cover that covers the book itself is connected to the flat surface of the book cover via an adhesive layer made of a heat-sensitive adhesive or an adhesive formed by providing a heat-sensitive adhesive layer on both sides of a transparent film substrate layer. It is to be glued to the part.
Since the adhesive layer and the adhesive body are configured to have different adhesive strengths to the front surface and the back surface of the surface-treated book cover to be bonded, they are configured to remain on the back surface of the book cover after peeling. Is done.

Therefore, the book cover does not adhere again once it is peeled off without impairing the appearance of the flat portion of the book cover. Therefore, when the book cover is opened, it can be recognized that the book cover has been completely opened once. In addition, it suppresses browsing and greatly restrains the sales form of selling as a new book again.

[0011]
