Abstract

The utility model discloses the structure design of a new book cover, and the inner cover of the old plastic book cover is changed from the square shape into an inwardly curved shape in the design. The utility model not only can save material, but also can bring convenience to the insertion and extraction of books, so the improved design of the utility model is worth to generalize.

Description

Plastic book cover

The utility model belongs to a kind of cultural goods, a kind of outer strip of paper used for sealing of books that is used for of saying so tool.

Book or notebook are used a kind of plastic wrappage always, form by crust and two endotheliums, endothelium is less, and hot pressing forms two pockets on crust, the outer strip of paper used for sealing of notebook or book (making hardboard usually) inserts among two pockets, form the outer strip of paper used for sealing of plastics of books, the endothelium of used this strip of paper used for sealing is a rectangle, and its pocket of hot-forming back is darker, install and remove very inconveniently, and take material.

The purpose of this utility model provides a kind of structural design of novel plastic strip of paper used for sealing, its energy economical with materials, and make dismounting become very convenient.

Design of the present utility model is the design that improves two endotheliums, the rectangle endothelium is dug down one form concave shape, hot pressing still can keep its fixedly performance of books later on crust like this, but its dismounting is very convenient with regard to what become, and about successively material (calculating by endothelium) 50%.

How further specify goal of the invention of the present utility model below in conjunction with accompanying drawing realizes:

Fig. 1 is the structural representation of the novel book front cover of indent circle.

Fig. 2 is the indent triangle.

Fig. 3 is that indent is trapezoidal.Wherein 1 is crust, and 2 is endothelium.

From accompanying drawing 1 as can be seen, improve to be designed to the circular endothelium of indent 2 its processing backs and crust 1 hot pressing together, promptly form the utility model, also can as Fig. 2, Fig. 3 make the indent triangle or indent trapezoidal, embodiment illustrated in fig. 1 is preferred embodiments.

By the novel strip of paper used for sealing that above structure is made, its fastening part to the books edge does not change effective length, but inserts or to take out the books crust all very convenient because of drop centre type makes, and inner concave is the saving part.Thereby its performance has improvement and strip of paper used for sealing cost significantly to reduce.

The book front cover that utilizes the utility model design to make can be saved material 15%, and uses greatly conveniently, thereby application value is arranged, because these articles for use are the consumer goods of whole society's extensive use, thereby its social benefit and economic benefit are fairly obvious.

Claims

1, a kind of plastics book front cover, by crust, the two piece endotheliums of hot pressing on crust are formed, and it is characterized in that two endotheliums are concave shape.

2, according to the said plastics book front cover of claim 1, it is characterized in that two endothelium concave shaped are the indent circle, indent triangle or indent are trapezoidal.
