A kind of easy-opening list flanging snap fastener bag
Technical field
The utility model relates to Document folio, particularly relates to a kind of easy-opening list flanging snap fastener bag.
Background technology
Existing snap fastener bag is to comprise bag, loam cake mostly; And right by female snap fastener that is separately positioned on the said bag outside and loam cake inboard correspondence position and snap fastener that sub-snap fastener is formed, said bag comprises two kinds, a kind of is the fixed edge bag; The dual-side of said fixed edge bag, base and opening edge do not have thickness; No extension function, capacity is less, and it is also smaller that the opening of accessing file is opened amplitude; Another kind is three flanging bags, and the dual-side of said three flanging bags, base all are the extension flangings, and said flanging extends can increase the thickness and the ductility of snap fastener bag, and the capacity of bag is increased relatively, still, and also corresponding materials and the cost of having increased.At present do not see that as yet the advantage that has above-mentioned two kinds of bags concurrently is arranged, promptly the capacity of bag has relative increase, and it is bigger that opening is opened amplitude, and the easy-opening snap fastener bag of single flanging bag that materials and cost do not increase as far as possible.
Summary of the invention
The utility model technical problem to be solved is the defective that remedies above-mentioned prior art, and a kind of easy-opening list flanging snap fastener bag is provided.
The technical problem of the utility model solves through following technical scheme.
This easy-opening list flanging snap fastener bag; Comprise bag, loam cake; And it is right by female snap fastener that is separately positioned on the said bag outside and loam cake inboard correspondence position and snap fastener that sub-snap fastener is formed; Said bag comprises the front panel that is provided with female snap fastener, the back plate that is not provided with female snap fastener and plate is used in the bookbinding of fitting, and said bag and the integrated plate of loam cake, and its joint portion is a laterally steering bending line parallel with the bag opening edge.
The characteristics of this easy-opening list flanging snap fastener bag are:
Said bag is single flanging bag; Promptly a side and base are the fixed edges of existing fixed edge bag, and another side is the extension flanging, are the combinations of existing fixed edge snap fastener bag and flanging snap fastener bag; Both increased the capacity of bag relatively; It is bigger to make opening open amplitude, has reduced the plane of flattening materials on a side and base again, makes cost of manufacture descend.
The technical problem of the utility model solves through following further technical scheme.
Said applying bookbinding is extended by the both sides of said front panel with plate, fits with the inner face of said back plate and binds.
Said applying bookbinding is extended by the both sides of said back plate with plate, fits with the inner face of said front panel and binds.
The utility model with the beneficial effect that existing snap fastener bag is compared is:
The utility model outward appearance is practical, and functional promotion can increase certain product capacity, does not increase the cost of product again as far as possible, and the increase opening opens amplitude, opens easily.
Description of drawings
Fig. 1 is the isometric front view of the utility model specific embodiment;
Fig. 2 is the plate plane of Fig. 1.
The specific embodiment
Below in conjunction with the specific embodiment and contrast accompanying drawing the utility model is described.
The specific embodiment one
A kind of easy-opening list flanging snap fastener bag shown in Fig. 1~2; Comprise bag, loam cake 1; And it is right by female snap fastener 2 that is separately positioned on the bag outside and loam cake 1 inboard correspondence position and snap fastener that sub-snap fastener 3 is formed; Bag comprise the front panel 4 that is provided with female snap fastener 2, the back plate 5 that is not provided with female snap fastener and the bookbinding of fitting with plate 6, and bag and loam cake 1 integrated plate, its joint portion is a laterally steering bending line 7 parallel with the bag opening edge.
Bag is single flanging bag; Be that right edge 8 is bag industry term---fixed edges of no thickness of existing fixed edge bag with base 9, and left side 10 is extension flangings, is the combination of existing fixed edge snap fastener bag and flanging snap fastener bag; Both increased the capacity of bag relatively; It is bigger to make opening open amplitude, has reduced the plane of flattening materials on a side and base again, makes cost of manufacture descend.
Plate shown in Figure 2 is the entire plate plate plane figure of this specific embodiment one.The plate of extension flanging in left side is to be provided with the plate that extends in front panel 4 left sides of the bag of female snap fastener 2; Having with base 9 left end points above it is three longitudinally guiding bending lines that an end extends downwards; Middle longitudinally guiding bending line is the longitudinally guiding bending line of outside bending, and the longitudinally guiding bending line of both sides is longitudinally guiding bending lines of inside bending.Also extending in the both sides of front panel 4 has one to fit bookbinding with plate 6 with the inner face of back plate 5.
The specific embodiment two
A kind of easy-opening list flanging snap fastener bag, basic composition is with the specific embodiment one, and difference is:
The plate of extension flanging in left side is not to be provided with the plate that extends in back plate 5 left sides of the bag of female snap fastener; Having with base 9 left end points above it is three longitudinally guiding bending lines that an end extends to the top; Middle longitudinally guiding bending line is the longitudinally guiding bending line of outside bending, and the longitudinally guiding bending line of both sides is longitudinally guiding bending lines of inside bending.Also extending in the both sides of back plate 5 has one to fit bookbinding with plate 6 with the inner face of front panel 4.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.Those of ordinary skill for technical field under the utility model; Under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; And performance or purposes are identical, all should be regarded as belonging to the scope of patent protection that the utility model is confirmed by claims of being submitted to.
