Description

  The present invention relates to a book protective cover for protecting a book by covering the book with a heat-shrinkable film, a book to which the cover is attached, and a method for manufacturing the book with the protective cover.

  In recent years, book covers using shrink wrapping have been used particularly for comic books as a measure for preventing books from being read and stained.

  The shrink film used in the above shrink wrapping is usually transparent, so the cover, back, and back cover of the book can be seen at a glance even when the cover is put on. Can be guaranteed.

  Shrink wrapping for comic books puts the book in a cylindrical shrink film and heats the shrink film by heating the periphery of the book (front cover, back, back cover, small edge) with a heating gun. Adhere the shrink film to the book.

  Also, cover the cover part of the book with a shrink film and put it into a tabletop shrink wrapping machine, seal the shrink film corresponding to the upper and lower edges of the book, cut it, and shrink it with the heater provided inside There is also known an automatic shrink wrapping apparatus in which a film is thermally shrunk to be in close contact with a book (for example, Patent Document 1).

  The above-described shrink wrapping prevents the book from being opened by bringing a shrink film into close contact with the outer periphery (body portion) of the book.

Registered Utility Model No. 3067592

  However, the conventional shrink wrapping for books described above is effective for comic books that can be sold without opening the contents, but there is a problem that it cannot be applied to binding books such as utility books and picture books.

  In detail, people who want to purchase utility books often make sure that the necessary technical contents are published there, and cover the periphery of the book with a shrink film like a comic book. If you do, you will be shunned because you do not know the contents.

  In the present invention, the heat-shrinkable film preferably has a thickness of 20 μm to 60 μm.

  In the present invention, the heat-shrinkable film can be selected from any one of a polyester shrink film, a polystyrene shrink film, a polyolefin shrink film, and a polyvinyl chloride shrink film.

  In the present invention, it is preferable that the book protection cover is formed in a bag shape in a portion folded inside the front cover and a portion folded inside the back cover.

  Moreover, this invention makes a summary the book to which the book protective cover which has the said structure was attached.

  Moreover, this invention is a manufacturing method of the book with a protective cover, Comprising: The manufacturing method of the book with a protective cover which has the process of attaching the book protective cover which has the said structure to a book, and the process of carrying out the heat shrink of the said book protective cover. It is.

  According to the book protection cover of the present invention, the contents of the book can be viewed, and the book can be protected at a low cost.

  According to the book to which the book protection cover according to the present invention is attached, it is only necessary to replace the book protection cover when returned, and there is an advantage that it is not necessary for the publisher to replace the cover and the belt with a new one. .

  According to the method for producing a book with a protective cover of the present invention, the book can be packaged with the book protective cover by a simple method.

It is the perspective view which showed the book protection cover which concerns on this invention. It is a perspective view which shows the state which attached the book protection cover which concerns on this invention to the book.

  Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

  FIG. 1 is a perspective view showing a book protection cover (hereinafter abbreviated as a protection cover) according to the present invention, and shows a state before the book is covered.

  The protective cover 1 is composed of at least a uniaxially stretched plastic film for shrink packaging, a front cover cover portion 2 covering the front cover portion of the book, a back cover portion 3 covering the back portion, and a back cover portion A back cover cover portion 4 that covers the cover, a cover cover folding portion 5 that is folded back from the cover cover portion 2, and a back cover folding portion 6 that is folded back from the back cover cover portion 4. Both the front cover folding part 5 and the back cover folding part 6 are formed in a bag shape.

  Further, the front cover folding part 5 is adhered to the upper and lower edges of the front cover cover part 2 by heat sealing (the part marked with symbol x in the figure), and the back cover folding part 6 is also back by heat sealing. It is bonded to the upper edge and the lower edge of the cover cover portion 4.

  As the plastic film, any one of polyester, polystyrene, polyolefin, and polyvinyl chloride shrink films can be used.

  The thickness of the protective cover 1 is preferably in the range of 20 μm to 60 μm, more preferably 30 μm to 50 μm.

  If the plastic film is thin, it is easy to tear, and if it is too thick, the shrinkage stress of the plastic film increases, and there is a possibility that the cover of the book covered with the cover will be warped after heat shrinkage.

  The heat shrinkage rate of the protective cover 1 is preferably 10 to 60%, more preferably 20 to 50% in the main shrinkage direction (the direction surrounding the body of the book) in hot water at 70 ° C. It is.

  If the heat shrinkage rate is too small, there is a risk that the book will loosen and cannot be brought into close contact with the book. If it is too large, the front and back covers may be warped after heat shrinkage. .

  FIG. 2 is a perspective view showing a state in which the protective cover 1 is attached to a book 7 to be packaged. In addition, the code | symbol 7a in this book 7 is a front cover, 7b is a back part, 7c is a back cover, 7d has shown the fore edge. 8 is a book cover attached to the book 7, 8a is a front cover cover look-back, 8b is a back cover cover look-back, and 9 is a belt.

  A clearance allowing for heat shrinkage is provided between the protective cover 1 of the book 7 and the width L 'of the protective cover 1 is 1.01L-1 when the cover width of the book to be packaged is L. Set to a range of 3L.

  Further, when the height of the book to be packaged is H, the longitudinal length H ′ of the protective cover 1 is set in the range of 1.01H to 1.15H.

  The book 7 to which the protective cover 1 is attached is then put into a book packaging shrink device (not shown). This shrink device is configured to perform a process of attaching the protective cover 1 to the book 7 and a process of thermally shrinking the protective cover 1 with a heater over time.

  When the protective cover 1 is heat-shrinked by the heat shrinking process, the protective cover 1 is in close contact with the front cover 7a and the back cover 7c of the book 7. You can see the contents of the book freely later.

  Since the book 7 is usually provided with the book cover 8 and the band 9, the protective cover 1 is packaged together with the cover.

  In addition, the protective cover 1 may be provided with a notch in the back side cover portion 3, for example, or may be perforated in the vertical direction so that it can be easily removed.

  In addition, for example, letters and logos of store names, coloring or designs for decoration, symbols for classification, and the like can be printed on the protective cover 1.

  An English version of Harry Potter was prepared as a book to be packaged, and each shrink film shown below was used as a material for the protective cover 1 having the above-described configuration.

  The horizontal width L ′ of the protective cover 1 was 1.1 L, and the vertical length H ′ was 1.03H.

The book to which the protective cover 1 was attached was put into a shrink device, and the protective cover 1 was heat-shrinked so as to adhere to the cover of the book.
As a result of packaging using each of the above shrink films, the cover of the book could be closely packed without sagging.
