Description

A kind of adjustable dust jacket

Technical field

The utility model relates to a kind of plastics dust jacket, particularly relates to a kind of adjustable dust jacket that can adapt to different books thickness.

Background technology

The plastics dust jacket that existing bag books are used is in order to solve with paper bag book complexity, to be difficult to grasp and technical problem that the papery cover damages easily occurs.It generally is made up of inside and outside two layers of plastic thin films, skin is a block length square plastic film, internal layer is two block length square plastic films, and upper end, lower end and the outer end edges of two block length square plastic films of internal layer are joined with upper end, lower end and the outer end edges of outer field rectangle plastics film respectively.This plastics dust jacket is more durable and be easy to use than papery dust jacket, but because it is a fixed dimension, therefore can not adapt to the needs of the variation of books thickness.

Chinese patent literature CN 2339401Y discloses a kind of " the cover big envelope that adapts to different-thickness ", it is made up of the thin-film material of inside and outside two-layer hot pressing knot or glue bond, be provided with the regulatory region of the adjusting length of being made up of 3-5 openings within it in the middle of the layer, Ceng two ends are provided with the ending finalization area of viscose top within it.During use, the front cover of books and back cover are inserted in the opening of the regulatory region that chooses, the books that close then fold to the same size with books with the two ends redundance in all, tear the viscose glue ceiling, the interior part that folds back are cemented get final product.Though this cover big envelope can adapt to the books of different-thickness, still more time-consuming when it uses, the regulatory region of band opening is the cost of manufacture height not only, and each opening part is damaged easily.

The utility model content

The purpose of this utility model provides a kind of adjustable dust jacket of various books thickness of adaptation simple in structure, easy to use.

The technical scheme that realizes the utility model purpose is a kind of adjustable dust jacket, comprises outer membrane and internal layer membrane.Outer membrane is a rectangle.Internal layer membrane comprises rectangular first cover band forming belt and the rectangular second cover band forming belt on the same side that is positioned at outer membrane, and the first cover band forming belt is positioned at the left part of outer membrane, the place that takes over, the middle part that the second cover band forming belt is positioned at outer membrane.Upper end, lower end and the left end edge of the first cover band forming belt melts by hot pressing with outer upper end, lower end and left end edge respectively and is bonded and fixed at.The edge, top and bottom of the second cover band forming belt melts by hot pressing with edge, outer top and bottom respectively and is bonded and fixed at.Outer membrane comprises regulatory region that is positioned at the second cover band forming belt right side and the finalization area that is positioned at the regulatory region right-hand member.On this finalization area viscose top is arranged, be stained with ceiling on the viscose top.

Described viscose top is shorter in length than finalization area length.

Thickness outer and the internal layer membrane material is 0.09 to 0.12mm.

The utlity model has positive effect: (1) the utility model only takes in use book cover is inserted in the page cover that is formed by the first cover band forming belt and outer membrane, back cover is inserted the capable page cover that becomes of the second cover band forming belt and outer membrane, then according to books thickness, regulatory region and finalization area are folded back, adhere on the second cover band forming belt and get final product; Using method is simple, need not use any instrument easily books to be wrapped, and can adapt to the requirement of different books thickness.(2) the utility model is simple for structure, and cost of manufacture is low, and manufacturer only need produce by several different format sizes, and the books that can satisfy all thickness use.(3) when viscose top of the present utility model is shorter in length than finalization area length, save viscose top on the one hand; On the other hand after viscose top adheres on the second cover band forming belt, can be very easily the finalization area and the second cover band forming belt be separated, so not only can adjust bonding position and dust jacket and books are fitted more but also dust jacket can have been taken off the books that are used to wrap other from books from the upper end or the lower end of finalization area.(4) when the thickness of skin of the present utility model and internal layer membrane material was 0.09 to 0.12mm, dust jacket thickness and pliability were moderate, good hand touch.

The specific embodiment

(embodiment 1)

See Fig. 1 and Fig. 2, adjustable dust jacket comprises outer membrane 1, internal layer membrane 2, viscose top 3 and ceiling 4.The material of outer membrane 1 and internal layer membrane 2 is a polyethylene, and its thickness is 0.11mm, selects such material and thickness, can obtain the preferable effect of dust jacket toughness and feel.

Outer membrane 1 is a rectangle, and its right part comprises regulatory region 1-1 and finalization area 1-2.

Internal layer membrane 2 comprises rectangular first cover band forming belt 2-1 and the rectangular second cover band forming belt 2-2 on the same side that is positioned at outer membrane 1, and the first cover band forming belt 2-1 is positioned at the left part of outer membrane 1, the place that takes over, the middle part that the second cover band forming belt 2-2 is positioned at outer membrane 1.Upper end, lower end and the left end edge of the first cover band forming belt 2-1 melt by hot pressing with outer membrane 1 upper end left part, lower end left part and left end edge respectively and are bonded and fixed at.The such first cover band forming belt 2-1, three ends are fixedlyed connected with outer 1, form the page cover of right-end openings, are used to insert book cover.The edge, top and bottom of the second cover band forming belt 2-2 melts by hot pressing with edge, outer membrane 1 top and bottom respectively and is bonded and fixed at, thus the page cover of the equal opening of end about forming.Can be passed by the books back cover between such second cover band forming belt 2-2 and the outer membrane 1.

The regulatory region 1-1 of outer membrane 1 is positioned at the right side of the second cover band forming belt 2-2, and the finalization area 1-2 of outer membrane 1 is positioned at the right-hand member of the regulatory region 1-1 of outer membrane 1.

Viscose top 3 is a double faced adhesive tape, and the one side of viscose top 3 is bonded and fixed at outer membrane 1, and viscose top 3 is positioned on the finalization area of outer membrane 1, and ceiling 4 is pressure-sensitive paper slip or plastic film strip, is bonded on the viscose top 3, is used to protect viscose top 3.

See Fig. 3 and Fig. 4; during use; book cover is inserted in the page cover of the first cover band forming belt 2-1 and outer membrane 1 formation; the books back cover is passed second cover band forming belt 2-2 and the outer membrane 1 formed page cover, and the books that close then fold back regulatory region 1-1 together with finalization area 1-2; thickness according to books; select the position of bonding, tear the ceiling 4 on the bonding strip 3, bonding strip 3 is bonded to the second cover band forming belt 2-2 upward gets final product.

(embodiment 2)

See Fig. 1 to Fig. 4, the present embodiment remainder is identical with embodiment 1, and difference is: the length of the finalization area 1-2 that is shorter in length than outer membrane 1 of viscose top 3.

The adjustable dust jacket of said structure, after its finalization area 1-2 and the second cover band forming belt 2-2 are bondd by bonding strip 3, certain bonded distance that do not have is just left in the top and bottom of finalization area 1-2, if in use, bonding position does not choose or is sticking oblique, just can pinch finalization area 1-2 upper and lower side with finger does not have bonded part that the finalization area 1-2 and the second cover band forming belt 2-2 are separated the operation that bonds again from the bonded part.And when not often use of the books that wrapped, also dust jacket can be taken off from books, be used to protect other books.
