The compression storage bag of prior art (please in conjunction with referring to Fig. 7 to shown in Figure 11) is made the dimetric sack 1 that can place the big or small article of cotton-wadded quilt with air-tightness plastic film 2 usually, one side the structure of the import and export 3 that can open and close with pressure-sealing zipper 6 being provided with of sack 1.
The compression storage bag of this structure as is opened pressure-sealing zipper 6 from importing and exporting 3 to the inner cotton-wadded quilt etc. that inserts of storage bag in use, extracts a bag thing in-to-in air with dust collecting fan then, shut pressure-sealing zipper 6 after, cotton-wadded quilts etc. keep compressive state.By dwindling the dilatability article, in locker, just can deposit compression storage bags such as more cotton-wadded quilt.
See also Fig. 7 to Figure 11, they represent each different example of prior art compression storage bag respectively.
See also Fig. 8 and shown in Figure 9, what Fig. 8 and Fig. 9 represented is the structural representation of prior art compression storage bag the 1st example, in this embodiment, compression storage bag 1 is to form quadrangle by two air-tightness plastic films 2 that overlap, wherein welding is carried out with weld bond 3 in three limits, in addition on one side as exhausr port, thereby forms bag thing 5, import and export 4 total lengths of this bag thing 5 adopt pressure-sealing zipper 6, form to import and export 4 structures that can carry out open and close.
See also shown in Figure 9, above-mentioned pressure-sealing zipper 6 is that the one side at the banded plastic film 7 that uses airtight material is provided with the raised line 8 that covers total length at length direction, form male portion material 9, be provided with the chase 10 that can flexiblely be meshed with raised line 8 on the another side of banded plastic film 7, this chase 10 covers total length at length direction and forms female material 11, and female material 11 matches with male portion material 9.In the inboard of the import and export 4 of bag thing 5, hero portion material 9 and female material 11 banded plastic films coincide, weld bond 12 welding total lengths are alongst used at the open end of import and export 4 and the edge of the corresponding banded plastic film 7 of this open end edge, are provided with the structure of open and close thus in the inside of importing and exporting 4.
Please in conjunction with Fig. 9 referring to Fig. 8 (a) with (b), the welding that carry out at the two ends of import and export 4 in bag thing 5 is handled and is formed weld portion 13, this weld portion 13 is two plastic films, 2, the two banded plastic films 7 that form bag thing 5 at the raised line 8 of pressure-sealing zipper 6 and chase 10 under the ingear state, adds up to four plastic films and the raised line 8 and the chase 10 that are meshed carry out the while welding and form weld portion 13; And this weld portion 13 continues mutually with weld bond 3.
When preserving cotton-wadded quilt etc., open pressure-sealing zipper 6, in sack 5, insert cotton-wadded quilt from the import and export 4 of sack 5, more than half locking of pressure-sealing zipper 6 with 1 compression of above-mentioned compression storage bag.In import and export 4 parts of opening with pressure-sealing zipper 6 to the inner suction pipe that inserts dust collecting fans of sack 5, extract air in the sack 5 with dust collecting fan, shut pressure-sealing zipper after, cotton-wadded quilt is just preserved compressive state.
But, when extracting the air of sack 5, when import and export 4 are opened, just can not extract the air in the sack 5 with dust collecting fan.Therefore, after putting into cotton-wadded quilt, the raised line of pressure-sealing zipper 68 and chase 10 begin to be meshing with each other from importing and exporting an end of 4, only stay the space that can insert suction pipe.The suction pipe that inserts dust collecting fan with the part place that opens of pressure-sealing zipper 6 is to sack 5 inner extracting airs, extracts suction pipe after extracting end, and the separating part of pressure-sealing zipper 6 must close rapidly.
See also Figure 10 and shown in Figure 11, what Figure 10 and Figure 11 represented is the structural representation of prior art compression storage bag the 2nd example, in this embodiment, compression storage bag 1a is for the operation of extracting air in the sack 5 is more oversimplified, strive for improving the made sack of extraction efficiency, roughly the same with the structure of the 1st routine compressed bag 1, import and export 4 and other associated components are set on sack 5, for example, appropriate location, bottom at sack 5 is provided with extracting part 14, and the setting of this extracting part 14 is in order to insert the suction pipe of dust collecting fan therein.
See also shown in Figure 11ly, this extracting part 14 is made up of two plastic films 15 that combine with sack 5; Two plastic film 15 both sides of the edge weldings, formation can be inserted the cylindrical shell 16 of the outer diameter flat of dust collector suction pipe, insert inner in the tangent plane 17 that the part of this cylindrical shell 16 is provided with from sack 5, the plastic film 2 that will form sack 5 airtight of tangent plane 17 carries out welding with the plastic film 15 usefulness weld bonds 18 of cylindrical shell 16, in the inside of the outer openings end of above-mentioned cylindrical shell 16, the pressure-sealing zipper 6a that design is identical with sack 5, it is airtight that outer openings also can be carried out.
During with the compression storage bag 1a compressed storage cotton-wadded quilt of the 2nd example, at first, from importing and exporting 4 to sack 5 inner cotton-wadded quilt etc., the pressure-sealing zipper 6 that closes, the total lengths of airtight import and export 4 inserted, then, in the cylindrical shell 16 of extracting part 14, insert dust collector suction pipe, extract air in the bag portion 5, at last, extract suction pipe with dust collecting fan, the close pressure-sealing zipper 6a of cylindrical shell 16 makes cotton-wadded quilt etc. keep confined state.
