The further improvement of the utility model PUR big envelope is, the surface of bending spine-sealing has lines or groove, and the side of front cover is connected with the surface that bends spine-sealing by PUR.
Brief description of the drawings
Fig. 1 is the schematic top plan view of the utility model PUR big envelope;
Fig. 2 is the schematic side view of the utility model PUR big envelope.
Detailed description of the invention
For the benefit of the understanding to structure of the present utility model, describes below in conjunction with drawings and Examples.
With reference to Fig. 1, be the schematic top plan view of the utility model PUR big envelope, as shown in Figure 1, the utility model provides a kind of PUR big envelope, comprising: the back cover 1 with bending spine-sealing 10; And the front cover 2 being connected with bending spine-sealing 10 by PUR, back cover 1 is positioned under front cover 2.
With reference to Fig. 2, for the schematic side view of the utility model PUR big envelope, shown in Fig. 2, back cover 1 is made up of two kinds of different materials respectively with front cover 2, in the present embodiment, preferably dermatoglyph paper is as the material of back cover 1, can preferably clear plastic foil as the material of front cover 2.Apply EVA PUR and be coated with on the limit, left side of front cover, more transparent front cover 2 is connected in to the surface that bends spine-sealing 10 in back cover 1.In figure, bending ridge 10 forms through twice bending, and front cover 2 is connected in the lower surface of bending spine-sealing 10.Further, the firmness connecting for increasing PUR, below can doing on the surface of bending spine-sealing 10, processing is processed: be one, matsurface by the Surface Machining of bending spine-sealing 10; Two, on the surface of bending spine-sealing 10, tiny lines or groove are set.These two kinds processing is processed and all can be made to use the firmness that EVA melt viscosity is attached after connecing better.
With this, complete the seal sleeve structure of an attractive in appearance and firm practicality.
Complete after above-mentioned implementation process, should be able to embody following characteristics of the present utility model:
Mode by PUR hot melt couples together back cover 1 and front cover 2, attractive in appearance and firmly practical.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thereby some details in embodiment should not form restriction of the present utility model, the utility model by the scope defining using appended claims as protection domain.
