Abstract
The utility model discloses a loose-leaf document envelop, comprising a cover, a back cover as well as a spine which is connected therewith. Wherein grid salient is formed on an inner surface at the middle of the spine, the surface of the salient is pasted with hot melting bands. In the loose-leaf document envelop of the utility model, documents or book cores are pasted through the hot melting bands, the grid salient is formed on the inner surface at the middle of the spines, the uniform distribution of the hot melting bands when the hot melting bands are melted in hot is ensured, thereby the bookbinding quality is increased.
Description
Technical field
The utility model relates to a kind of big envelope, relates in particular to a kind of loose-leaf file big envelope.
Background technology
Loose-leaf file big envelope is a file or bookblock strip of paper used for sealing commonly used, can bound document or bookblock, prevent that file and bookblock from damaging.For various dismountable loose-leaf file big envelopes are provided, generally all be bookblock to be linked to each other with big envelope by jockey is set at the spine place, the most complex structure of these jockeys, use inconvenience, when particularly occurring skipping, rebind more consuming timely, increased cost of labor.
Fig. 1 is the loose-leaf file seal sleeve structure schematic diagram of existing employing hot melt bar, see also Fig. 1, existing loose-leaf file big envelope comprises front cover 1, back cover 2 and the spine 3 that connects them, wherein, is pasted with hot melt bar 4 in the middle of the described spine 3, such loose-leaf file big envelope is pasted file or bookblock by hot melt bar 4, easy to use, and can guarantee to skip and can repeat bookbinding when taking place, if improper but the hot melt bar is pasted, cause hot melt bar skewness during hot melt easily, influence bookbinding quality.
The utility model content
Technical problem to be solved in the utility model provides a kind of loose-leaf file big envelope, uses the hot melt bar to paste file or bookblock, and the hot melt bar evenly distributes can guarantee hot melt the time.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of loose-leaf file big envelope, comprise front cover, back cover and the spine that connects them, wherein, inner surface forms latticed projection in the middle of the described spine, and described protrusion surface is pasted with the hot melt bar.
Above-mentioned loose-leaf file big envelope, wherein, described latticed projection is the silica gel heating film.
Above-mentioned loose-leaf file big envelope, wherein, described hot melt bar is elongated cuboid bar, described hot melt bar length is less than the length of described spine.
Above-mentioned loose-leaf file big envelope wherein, includes the envelope tongue on the described front cover, described front cover and described envelope tongue connecting place are carved with crease line, are pasted with double faced adhesive tape on the described envelope tongue.
Above-mentioned loose-leaf file big envelope wherein, is printed with reflecting strips on described front cover or the back cover.
The utility model contrast prior art has following beneficial effect: the loose-leaf file big envelope that the utility model provides, paste file or bookblock by the hot melt bar, inner surface forms latticed projection in the middle of the described spine, and the hot melt bar evenly distributes when guaranteeing hot melt, thereby improves bookbinding quality.In addition, the utility model adopts the silica gel heating film to form above-mentioned latticed projection, further improves binding efficiency and quality.
Description of drawings

Fig. 2 is a loose-leaf file big envelope spine structural representation of the present utility model;
Fig. 3 is the loose-leaf file seal sleeve structure schematic diagram of band envelope tongue of the present utility model.
Among the figure:
1 front cover, 2 back covers
3 spines, 4 hot melt bars
5 envelope tongues, 6 double faced adhesive tapes
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 2 is a loose-leaf file seal sleeve structure schematic diagram of the present utility model.
See also Fig. 2, loose-leaf file big envelope of the present utility model comprises front cover 1, back cover 2 and the spine 3 that connects them, wherein, form latticed projection in the middle of the described spine 3, described protrusion surface is pasted with hot melt bar 4, when bound document or bookblock, file big envelope spine 3 heating of paper will be accompanied, make 4 fusings of hot melt bar, owing to form latticed projection in the middle of the spine 3, therefore the hot melt bar 4 after the fusing is uniformly distributed in the described latticed projection; Before PUR solidifies, exert pressure at the big envelope waist, compress paper and big envelope; Front cover 1 and back cover 2 are at the stressed place of waist, and general hot melt bar 4 is elongated cuboid bar, respectively produces a folding line along hot melt bar 4, so just finish the bookbinding of file or bookblock, and PUR infiltrates in the bookblock, and bookblock is sticked on the big envelope.
In order further to improve binding efficiency and quality, described latticed projection is the silica gel heating film, and during hot melt, the silica gel heating film can produce heat and accelerate 4 fusings of hot melt bar.
In addition, pollute big envelope or bookblock in order to prevent to paste, the length of hot melt bar 4 is less than the length of spine 3, hot melt bar 4 is apart from the about 0.5cm in spine 3 both sides, when hot melt is handled like this, both guaranteed that bookblock and big envelope closely pasted, overflowed from spine 3 when preventing 4 fusings of hot melt bar again.
Fig. 3 is the loose-leaf file seal sleeve structure schematic diagram of band envelope tongue of the present utility model.
See also Fig. 3, also include envelope tongue 5 on the front cover 1 of the present utility model, described front cover 1 and described envelope tongue 5 connecting places are carved with crease line, are pasted with double faced adhesive tape 6 on the described envelope tongue 5.Like this, when loose-leaf file big envelope for a long time need not, when perhaps needing to file, can front cover 1 and back cover 2 be pasted by the double faced adhesive tape 6 of envelope on the tongue 5, thereby prevent to skip, prevent dust, file or bookblock in the protection loose-leaf file big envelope.Use file or bookblock in the loose-leaf file big envelope if desired, can tear front cover 1 and envelope tongue 5 along crease line.
Sometimes seek the thing that file compares headache often, seek file for convenience, loose-leaf file big envelope of the present utility model, can on front cover 1 or back cover 2, print reflecting strips, when needing to seek file, can turn off light, adopt the flashlight irradiation, the front cover 1 or the reflecting strips on the back cover 2 of loose-leaf file big envelope can be reflective under light-illuminating, thereby need to find the file of searching.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
