In addition, it is the situation of content as object in custody that packaging bag of the present invention can be suitable for fill liquid, but but also filling powder or solid, gel etc.In addition, though represented heavy section, cut-out portion and sealing base portion are located at the illustration on the female part, also can it be located on the male parts.
The structure that has the packaging bag of zipper tape:
The packaging bag 1 of this embodiment has bag 10 like Fig. 1 and shown in Figure 2, and this bag 10 will be through overlapping as the base film 11 of packing, form at its periphery formation side seal base portion 12 and back seal base portion 13.The inside face 10A of the peristome 14 of bag 10 is equipped with zipper tape 20; This zipper tape 20 has a pair of male parts 21 and female part 22, this a pair of male parts 21 and female part 22 comprise bite 23 and with banded base portion 211 of this bite 23 bonded assemblys sun side and the banded base portion 221 of cloudy side.The side seal base portion 12 of this zipper tape 20 from a side side seal base portion 12 to the opposing party is and is sealed on the bag 10 bandedly.In addition, the bite 23 of zipper tape 20 forms accommodation space 15 in the internal separation of packaging bag 1.
In addition, this packaging bag 1 is sealed to form through the bottom with bag 10 and is closed state during below bag 10, having taken in Fig. 1～3 behind the not shown content.
In addition, the user breaks a seal peristome 14 when Kaifeng, seals with zipper tape 20 again.
In addition, zipper tape 20 shown in the cross section structure of Fig. 2, have a side who constitutes by thermoplastic base resin banded male parts 21 and with the opposing party's of this male parts 21 interlocks female part 22.
Here, male parts 21 by be sealed in the banded base portion 211 of positive side on the bag 10, cross section for sagittate head 212 roughly and should the banded base portion 211 of sun side and the connecting portion 213 that couples together of head 212 integrally formed.
In addition, female part 22 and male parts 21 are the same has: be sealed in the banded base portion 221 of cloudy side on the bag 10; And be connected with the banded base portion 221 of this moon side and the cross section that forms is circular-arc the 1st hook portion 222 and the 2nd hook portion 223.The 1st hook portion 222 and the 2nd hook portion 223 constitute the groove shapes of the head 212 of the male parts 21 that can engage, get loose relatively.
In addition, the banded base portion 211 of the positive side of male parts 21 has: with inside face 10A roughly relatively and leak free base portion opposite face 211A; And form face 211B in the bite of bite 23 sides of a side opposite with base portion opposite face 211A.In addition, the banded base portion 221 of the cloudy side of female part 22 has: with inside face 10A roughly relatively and leak free base portion opposite face 221A; And form face 221B in the bite of bite 23 sides of a side opposite with this base portion opposite face 221A.
And in the zipper tape 20, the head 212 of male parts 21 and the 1st hook portion 222 of female part 22 and the 2nd hook portion 223 constitute bite 23.Through their interlock or disengagement, packaging bag 1 is just by sealing or Kaifeng.
The banded base portion 221 of cloudy side that is integrally formed with female part 22 is like Fig. 2 and shown in Figure 3, and having than the banded base portion 221 of cloudy side in an edge portion 224 of accommodation space 15 sides of bag 10 is thick-wall heavy section 31.
Be connected with in the end of accommodation space 15 sides of this heavy section 31 and form than heavy section 31 thin-walleds and with the cut-out portion 32 of accommodation space 15 and the outside band shape that separates.
Be connected with in the end of accommodation space 15 sides of cut-out portion 32 and form than banded base portion 221 heavy walls of cloudy side and be sealed in the sealing base portion 33 on the inside face 10A.
The gauge of heavy section 31 preferably 250 μ m above, below the 550 μ m, be more preferably 350 μ m above, below the 450 μ m.Under the situation of gauge less than 250 μ m of heavy section 31, the stress during open packing bag 1 is difficult to concentrate in the cut-out portion 32.On the other hand, when the gauge of heavy section 31 surpasses 550 μ m, then be difficult to form side seal base portion 12.
In addition, heavy section 31 forms to forming the narrow gradually narrow width shape of the inside face 10A width of the relative bag 10 of face 221B, promptly form width that the cross section the is outstanding tip side narrow echelon form of stenosis gradually with bite.
In addition, the top end face 311 of this heavy section 31 is sealed on the interior surface opposing 10A.Under this installing condition, the continuous end face 312 that is provided with cut-out portion 32 of heavy section 31 forms with respect to inside face 10A and approximate vertical.And heavy section 31 is less than the sealing intensity intensity of sealing base portion 33 on inside face 10A in the sealing on the inside face 10A.Sealing intensity is for example as shown in Figure 1, be utilized in be on the length direction (left and right directions of Fig. 1) of cut-out portion 32 the dotted line shape by leak free part sealing 311A, (seal area of the adhesive portion 331A that afterwards states and less seal area wait and adjust through making seal area than sealing base portion 33.
In addition, heavy section 31 forms more than the 0.5mm from the distance of the end of accommodation space 15 sides of the banded base portion 211 of edge part Zhiyang side of top end face 311 outer sides.That is, its reason is, and is might heavy section 31 bonding and can not obtain good Kaifeng and feel with the banded base portion of positive side 211 then when being sealed in heavy section 31 on the inside face 10A if also narrower than 0.5mm, or can not break a seal sometimes.And the cross section of heavy section 31 is that the one edge side of the outer side of trapezoidal top end face 311 is to leave the inclined-plane 313 of the banded base portion 211 of positive side, and this heavy section 31 can prevent when sealing the unfavorable condition bonding with positive side band shape base portion 211.
The side seal base portion 12 of cut-out portion 32 from a side side seal base portion 12 to the opposing party is banded, and forms to the band shape of extending with the direction (above-below direction among Fig. 3) of heavy section 31 end faces 312 quadratures.It is little that this cut-out portion 32 forms the sealing intensity of intensity ratio sealing base portion 33 on inside face 10A, promptly forms before sealing base portion 33 is peeled off from the inside face 10A of bag 10A, and cut-out portion 32 just is cut off.Specifically, the gauge of cut-out portion 32 preferably 10 μ m above, below the 80 μ m, be more preferably 30 μ m above, below the 60 μ m.Under the situation of gauge less than 10 μ m of cut-out portion 32, packaging bag 1 sometimes impact when falling etc. from exterior pressure cut off.On the other hand, when the gauge of cut-out portion 32 surpasses 80 μ m, then when Kaifeng, be difficult to sometimes cut-out portion 32 cut off with power on hand.In addition, the intensity of cut-out portion 32 be not limited to make the thin-wall part on a side side seal base portion 12 to the direction of the opposing party's side seal base portion 12, disperse to be provided with etc. with predetermined distance, the single-piece gauge is set in the situation of above-mentioned scope.
In addition, the width dimensions of cut-out portion 32, promptly with the length direction of zipper tape 20 roughly the size on the direction of quadrature (above-below direction among Fig. 3) preferably 0.3mm above, below the 1.5mm, be more preferably 0.8mm above, below the 1.2mm.Under the situation of width dimensions less than 0.3mm of cut-out portion 32, zipper tape 20 is being sealed in 10 last times of bag, might be difficult to carry out position alignment and make cut-out portion 32 be bonded on the banded base portion 211 of positive side or inside face 10A of male parts 21.On the other hand, when the width dimensions of cut-out portion 32 surpassed 1.5mm, then when cut-out portion 32 was cut off, cut-out portion 32 might extend and be difficult to cut off.
The side seal base portion 12 of sealing base portion 33 from a side side seal base portion 12 to the opposing party is band shape, and it is rectangular to form the cross section.
And sealing base portion 33 forms it and is sealed in the roughly the same face (with reference to Fig. 6) of top end face 311 on the inside face 10A that is sealed in sealing surface 331 and the heavy section 31 on the inside face 10A.Be provided with the adhesive portion 331A on the inside face 10A that is bonded in of pectination on the sealing face 331.As shown in Figure 1, this adhesive portion 331A has: along the length direction (left and right directions among Fig. 1) of cut-out portion 32 shape ground leak free line seal face 331A1 linearly; And link to each other with this line seal face 331A1 and be a plurality of end seal face 331A2 of the end face 333 of dotted line shape ground sealing sealing base portion 33.Here, utilize line seal face 331A1 to prevent spilling of content, utilize a plurality of end seal face 331A2 with stress concentration in cut-out portion 32.
In addition, sealing base portion 33 forms end face 312 almost parallels of its link to each other end face 333 be provided with cut-out portion 32 and relative heavy section 31, and with respect to the inside face 10A approximate vertical of bag 10.
Here, the male parts 21 co-extrusion modling methods capable of using of the formation zipper tape 20 of this embodiment obtain the head 212 and the connecting portion 213 that link to each other with the banded base portion 211 of positive side integratedly.Equally, female part 22 co-extrusion modling method also capable of using obtains 1st hook portion 222 and 2nd hook portion 223 continuous with the banded base portion of cloudy side 221 integratedly.If utilize this co-extrusion modling method moulding zipper tape 20, then can Fabrication procedure be oversimplified, can reduce manufacturing cost, can make zipper tape 20 continuously and stably.
Though male parts 21, the female part 22 of this zipper tape 20 are made up of poly-vinyl or polypropylene, preferably constitute by the polypropylene that is difficult to extend.Specifically, can use thermoplastic base resins such as HOPP, block polypropylene, random polypropylene (RPP), propylene-ethylene-butene 1 random terpolymer, the special soft resin of polyolefins or mixed these resins after compound.
In addition, as the resin that constitutes zipper tape 20, under the situation of using random polypropylene (RPP), the melt flow rate of this RPP (MFR) preferably 0.5～20g/10 minute is more preferably 1～15g/10 minute.
The extrusion molding property of the bite 23 that is integrally formed if the MFR of random polypropylene less than 0.5g/10 minute, then links to each other with banded base portion 211 of positive side and the banded base portion 221 of cloudy side is variation sometimes.On the other hand, if MFR greater than 20g/10 minute, then because the top of the 1st hook portion 222 of female part 22 and the 2nd hook portion 223 connecting portion 213 closed easily or male parts 21 falls down easily, therefore, is difficult to be extruded as the shape of the regulation that can open and close again sometimes.
Be sealed on the base film 11 that forms bag 10 through the zipper tape 20 that makes this structure,, thereby can obtain the packaging bag 1 of that kind shown in Figure 1 these base film 11 bags.

The manufacturing installation that has the packaging bag of zipper tape:
The manufacturing installation of the packaging bag that has zipper tape of first embodiment then, is described with Fig. 6～8.
The manufacturing installation that is used to make packaging bag 1 has bag portion.Fig. 6 representes to be sealed by the situation of collecting article by the main portion of bag portion.
In Fig. 6; Bag portion has: belt adhesive portion (not shown); This belt adhesive portion makes zipper tape 20 that never graphic belt unloading part sees off between a pair of base film 11 that never graphic packing unloading part is seen off, through bag belt adhesive portion zipper tape 20 is heat sealed to respectively on the base film 11; And closure, this closure to the base film 11 carried with respect to the throughput direction of base film 11 with predetermined distance, promptly with the Width of packaging bag 1 on the size corresponding intervals seal and fuse, form packaging bag 1.
Closure has a pair of seal bar 60, and this a pair of seal bar 60 clips and is filled with packaging bag 1 that content P and zipper tape 20 be closed and configuration relative to each other.
These seal bar 60 can be near each other, away from, when leaving mutually, the packaging bag 1 of taking in meaningful thing P remains on assigned position.Under this state, when seal bar 60 was near each other, a side seal bar 60 by being pressed on the sealing base portion 33, formed adhesive portion 331A through base film 11 thus on sealing base portion 33.
Here, as shown in Figure 7, a side seal bar 60 has the pushes protrusion 60A of the continuous pectination identical with adhesive portion 331A.As shown in Figure 8, the adhesive portion 331A of sealing base portion 33 is formed on the Width of bag 10 with Rack, and to form at length direction be the pectination of predetermined distance.The top of pushes protrusion 60A surpasses cut-out portion 32, is anchored on heavy section 31 and seals.
In this embodiment, seal in accommodation space 15 sides, when sealing, use the seal bar with pushes protrusion 60A 60 of the shape identical with adhesive portion 331A to zipper tape 20, can form adhesive portion 331A thus.Therefore, the packaging bag 1 that the power that can make available Kaifeng zipper tape 20 is easily peeled off heavy section 31 and cut-out portion 32 is cut off.
The action effect of first embodiment:
Adopt aforementioned the sort of packaging bag 1, the effect that can obtain to be described below.
That is, in above-mentioned first embodiment, it is thicker in an edge portion 224 of accommodation space 15 sides of cloudy side belt base portion 221 heavy section 31 to be set to wall.In the accommodation space 15 side settings of this heavy section 31 than the thin cut-out portion 32 of cloudy side belt base portion 221 walls.Accommodation space 15 sides in this cut-out portion 32 are provided with sealing base portion 33, and sealing base portion 33 is heavy wall and is sealed on the inside face 10A of the bag 10 that positive side belt base portion 211 is installed than cloudy side belt base portion 221.And; At the inside face 10A that positive side belt base portion 211 is installed heavy section 31 being installed than the little sealing intensity of sealing intensity of sealing base portion 33, and with than the little intensity of the sealing intensity of sealing base portion 33 with cut-out portion 32 form with the inside face 10A of bag 10 across at interval and with accommodation space 15 and the outside band shape that separates.
Thus, the zone that is impaled by the inside face 10A of heavy section 31, cut-out portion 32, sealing base portion 33 and bag 10 becomes roughly osed top state.Therefore; For the bag 10 that in accommodation space 15, contains content P that zipper tape 20 is installed; Even temporarily be applied in from outside or bag pressure inside, roughly the zone of closed state also becomes the buffer area of the pressure on 15 of the accommodation spaces that are applied to cut-out portion 32.Therefore; Even set the cut-out portion 32 of the intensity that when Kaifeng cut off easily for, can prevent that also for example cut-out portion 32 is because of extending, might when impacting next time, produce destructions, or according to circumstances producing pore, damage and make the especially unfavorable condition of water tightness etc. of leak tightness that accommodation space 15 and outside separate from outside or bag pressure inside.So, employing the present invention, thus can not produce in order to improve the leak tightness raising and to make cut-out portion 32 form unfavorable conditions such as heavy wall infringement Kaifeng property, good Kaifeng property and sufficient leak tightness can be provided.
In addition, in the first embodiment, heavy section 31 forms roughly the same gauge with sealing base portion 33.
Thus; When carrying out thermal welding by 60 pairs of heavy sections 31 of seal bar and sealing base portion 33; Butt seal bar 60 simultaneously almost on heavy section 31 and sealing base portion 33; On the sealing surface 331 of the top end face 311 of heavy section 31 and sealing base portion 33, receive the pressure of setting respectively, the thermal welding state of can bonding one-tenth setting.
That is, when arbitrary side becomes heavy wall, push seal bar 60 in order to seal the opposing party more powerfully, might damage cut-out portion 32 because of heat.In addition,,, might cut-out portion 32 extend and the damage leak tightness for thin-walled and be not sealed in rightly under the situation on the bag 10 at heavy section 31 when pressure is applied to 10 last times of bag from the outside.On the other hand, when heavy section 31 became heavy wall, sealing intensity increased, and when Kaifeng, made heavy section 31 when bag 10 is peeled off, need bigger power, might damage the Kaifeng sense.And, forming accordingly under the situation of seal bar 60 with different thickness in order to solve this unfavorable condition, the shape of seal bar 60 is just complicated, and installation cost increases, and the location during sealing is also numerous and diverse, might can't improve the manufacturing efficient of packaging bag 1.
