The specific embodiment

[the 1st example]

What Fig. 1 represented is the 1st example that applies the present invention in the three banding bags.

Three banding bag 10-1 shown in Figure 1 are formed by two identical shaped thin layers 11.This three bandings bag 10-1 comprises: have two side top 12a longitudinally of regulation sealed width w, two the side bottom 12b of sealing shape with general triangular and the horizontal base 12c with regulation sealed width w.In addition, this three bandings bag 10-1 has the incorporating section 13 of upper end open (symbol 12d) in the inboard.

The multilayer film etc. that each thin layer 11 by the multilayer film that can seal, for example comprises the three-decker of polyethylene terephthalate film, aluminium foil and straight chain shape low density polyethylene films constitutes.

Two side inward flange 13a, (2) longitudinally that incorporating section 13 utilizes (1) to be present in each 12a inboard, side top are present in the inboard of each side bottom 12b and become ground, obtuse angle from the lower end of each side inward flange 13a with each side inward flange 13a that bevelled two inclination inward flanges 13b and (3) are present in the inboard of base 12c and the horizontal base inward flange 13c of the lower end binding of each inclination inward flange 13b is formed its profile to the inside.

The whole longitudinal size of the three banding bag 10-1 that A among Fig. 1 represents, what B represented is the whole lateral dimension of three banding bag 10-1.What in addition, BP represented is the side outward flange 14a of three banding bag 10-1 or the intersection point between its extended line and base outward flange 14b or its extended line.IPa represents is intersection point between side inward flange 13a and the inclination inward flange 13b, and IPb represents is intersection point between inclination inward flange 13b and the base inward flange 13c.What a represented is to be the longitudinal size of the intersection I Pa of benchmark with intersection points B P, and what b represented is to be the lateral dimension of the intersection I Pb of benchmark with intersection points B P.

In three banding bag 10-1 shown in Figure 1, be that the longitudinal size a of the intersection I Pa of benchmark preferably is in the scope of 0.08A～0.71A with intersection points B P, more preferably be in the scope of 0.15A～0.65A.In addition, be that the lateral dimension b of the intersection I Pb of benchmark preferably is in the scope of 0.12B～0.48B with intersection points B P, more preferably be in the scope of 0.20B～0.40B.

Described number range is the material particular that can support oneself for the three banding bag 10-1 that make behind the collecting article of taking in liquid and body of powder etc. in incorporating section 13.Described number range is to select according to test and the test results that the following describes.

At the trial, made whole longitudinal size A be 240mm, whole transverse dimension B be 160mm, sealed width w be the maximum amount of taking in of 5mm, incorporating section 13 be 800cc, each thin layer 11 by thickness be among that multilayer film that straight chain shape low density polyethylene films that the polyethylene terephthalate film of 12 μ m, aluminium foil that thickness is 7 μ m and thickness are 50 μ m is laminated by adhesive layer constitutes, kind and Fig. 4 mark * the cooresponding three banding bags of combinations of values in the place of mark, △ mark and zero mark.In addition, prepared in the incorporating section 13 of each three bandings bag, to have taken in the snellen test of air being taken out, afterwards the upper end open heat-sealing (sealed width is 5mm) of incorporating section 13 become behind the tap water of 600cc sealing state.

Test method as shown in Figures 2 and 3, with finger tip pinch snellen test top margin central part (among the figure ● the position of mark) and on to make this snellen test after carrying be that the place of 50mm utilizes deadweight to drop to this horizontal surface FS from the height H of leaving water plane FS, each sack has been carried out five above-mentioned trials respectively, and by range estimation the state of landing has been estimated respectively.

Test results as shown in Figure 4, among the figure * mark represents is all to fall down after snellen test is landing in five times are attempted and once also not have the situation of self-support, what the △ mark among the figure was represented is that snellen test does not all fall down in five times are attempted, but can support oneself, but there is the situation of deviation in the self-support attitude, zero mark among the figure is represented is that snellen test does not all fall down in five times are attempted, but can support oneself and the self-support attitude does not have the situation of deviation.

The longitudinal size a of Fig. 4 is to represent recently that with respect to the percentage of whole longitudinal size A lateral dimension b recently represents with the percentage with respect to whole transverse dimension B.The unit of percentum is with 0.05 as base unit, but for * mark and the border of △ mark and the border of △ mark and zero mark, then use the unit of little numerical value to confirm the reasonableness on border as required than 0.05.

By test results shown in Figure 4 as can be known, if number range with the △ marked, be that the longitudinal size a of intersection I Pa is in the scope of 0.08A～0.71A and the lateral dimension b of intersection I Pb is in the scope of 0.12B～0.48B, snellen test is supported oneself.In addition, if with the scope of zero marked, promptly the longitudinal size a of intersection I Pa is in the scope of 0.15A～0.65A and the lateral dimension b of intersection I Pb is in the scope of 0.20B～0.40B, and snellen test is supported oneself with more stable attitude.

In above-mentioned test, because as what be accommodated in that collecting articles in the incorporating section 13 use is the tap water of difficult self-support in the liquid, therefore, infer also can obtain the result equal with Fig. 4 even take in the high liquid of viscosity ratio tap water and flowing power is tested than the body of powder of liquid difference.

The reason that can support oneself in described number range is not clear, but the process of the test of the snellen test that observation can be supported oneself as can be known, under the state of on the top margin central part that pinches snellen test with finger tip (among the figure ● the position of mark), having carried, tap water in the incorporating section 13 moves towards the below because of the weight of self, thereby the bottom of this incorporating section 13 is pushed open towards the outside and is expanded, and, along with this expands, the lower surface of snellen test, especially the part that has the non-rectilinear position of inward flange produces fold (conceptive comprise fold that is caused by depression and the fold that is caused by bending).If snellen test is dropped on the horizontal surface FS, then along with the growth of fold, the bottom of this snellen test becomes the form that is crushed, this snellen test with face state of contact roughly from standing on the horizontal surface FS.

Like this, if adopt three banding bag 10-1 shown in Figure 1, be that the longitudinal size a of the intersection I Pa of benchmark is in the scope of 0.08A～0.71A then by making with intersection points B P, and to make with intersection points B P be that the lateral dimension b of the intersection I Pb of benchmark is in the scope of 0.12B～0.48B, and three banding bag 10-1 behind the collecting article of taking in liquid and body of powder etc. in incorporating section 13 are supported oneself.

It is actv. that the fold formation portion 15 that is arranged on the inward flange 13b bottom that respectively tilts forms fold near position each fold formation portion 15 of three banding bag 10-1.On the other hand, the fold formation portion 16 that is formed on each side inward flange 13a bottom to form fold near position each fold formation portion 16 of three banding bag 10-1 be actv..

In addition, what represent among Fig. 8 is that each inclination inward flange 13b is provided with the situation that a fold formation portion 15 and each side inward flange 13a are provided with a fold formation portion 16, but also can (1) plural fold formation portion 15 be set on each inclination inward flange 13b and plural fold formation portion 16 is being set on each side inward flange 13a, perhaps (2) are only adopted the side in fold formation portion 15 and the fold formation portion 16 and are not adopted the opposing party, perhaps (3) only are provided with one or more fold formation portion 15 on the inclination inward flange 13b of a side, and perhaps (4) only are provided with one or more fold formation portion 16 on the side inward flange 13a of a side.In a word, if at least one side among side inward flange 13a and the inclination inward flange 13b is provided with fold formation portion, three banding bag 10-1 are supported oneself.

Certainly, fold formation portion same as described above is applied to also can obtain action effect same as described above among three banding bag 10-2 shown in Figure 5, shown in Figure 6 put the palms together before one bag 10-3 and the both sides envelope 10-4 shown in Figure 7.

[the 2nd variation]

The difference of three banding bag 10-1 shown in Fig. 9 (A) and three banding bag 10-1 shown in Figure 8 is: each side bottom 12b is provided with from two folding lines 17 of fold formation portion 15 to base outward flange 14b, and each side bottom 12b is provided with two folding lines 18 from the intersection point between each inclination inward flange 13b and the base inward flange 13c to base outward flange 14b.

Record in " reason that can support oneself " in the explanation of the 1st example, clearly, the influence that the fold that produces in the lower surface of snellen test can bring the self-support of snellen test, therefore, at this, in order on each side bottom 12b of three banding bag 10-1, to form fold respectively energetically, on each side bottom 12b, be respectively arranged with two

folding lines

17,18.

On each side bottom 12b, be respectively arranged with the occasion of two

folding lines

17,18, preferably shown in Fig. 9 (B), make adjacent two

folding lines

17,18 towards on the contrary, so that each side bottom 12b is the form bending gallantly of zigzag with the cross section because of each folding line 17,18.In addition, in Fig. 9 (B), as folding

line

17,18 expression be the folding line of cross section semicircular in shape, but the folding line that also can adopt the cross section to be in the shape of the letter V.By the way, each

folding line

17,18 can be by formation simply such as punch process.

According to experiment, if a side folding line 17 and the angle θ 1 that base outward flange 14b constitutes are in the scope of 21 degree～79 degree, and the opposing party's folding line 18 and the angle θ 2 that base outward flange 14b constitutes are in the scope of 51 degree～119 degree, then can form fold effectively along each

folding line

17,18, thus, can make each side bottom 12b bending gallantly.Because each folding line the 17, the 18th than the linear parts of the easy bending of other parts, even therefore each angle θ 1, θ 2 exceed above-mentioned angular range slightly, also can be enough to form the fold along each

folding line

17,18.

In addition, expression is the situation that each side bottom 12b is provided with two

folding lines

17,18 among Fig. 9 (A) and Fig. 9 (B), but the folding line more than three also can (1) be set on each side bottom 12b, perhaps (2) only are provided with the side in folding line 17 and the folding line 18 on each side bottom 12b, and perhaps (3) only are provided with more than one at least one side in the

folding line

17,18 on the 12b of the side bottom of a side.In a word, be provided with at least one folding line, three banding bag 10-1 are supported oneself as if at least one side among two side bottom 12b.

Certainly, folding line same as described above is applied to also can obtain action effect same as described above among three banding bag 10-2 shown in Figure 5, shown in Figure 6 put the palms together before one bag 10-3 and the both sides envelope 10-4 shown in Figure 7.

In addition, as the substitute of described folding line, linear parts or the less linear parts of (2) thickness that for example also can use (1) that the slit of length is arranged with the dotted line shape.These linear parts can't stipulate that as described folding line bending is reverse, but owing to be linear parts than the easy bending of other parts, are actvies for forming fold therefore.By the way, the linear parts of above-mentioned (1) and (2) also can form by punch process etc. with described folding line the samely simply.

[the 3rd variation]

In the 1st～the 4th example, what represent as each inclination inward flange 13b is the edge of linearity, but it is straight straight line that the inward flange 13 that respectively tilts need not, and the crooked slightly or inward flange 13b that respectively tilts of each inward flange 13b that tilts crawls slightly based on the tolerance of heat-sealing etc. and also can obtain action effect same as described above.

[the 5th example]

What Figure 10 represented is the 5th example that applies the present invention in the three banding bags.

Three banding bag 10-5 shown in Figure 10 are formed by two identical shaped thin layers 11.This three bandings bag 10-5 comprises: have two side top 12a longitudinally of regulation sealed width w, two the side bottom 12b of sealing shape with general triangular and the horizontal base 12c with sealed width w identical with side top 12a.In addition, this three bandings bag 10-5 has the incorporating section 13 of upper end open (symbol 12d) in the inboard.

Incorporating section 13 utilizes (1) to be present in two side inward flange 13a longitudinally of each 12a inboard, side top, (2) be present in the inside upper part of each side bottom 12b and become ground, obtuse angle two first inclination inward flanges of bevelled 13b1 to the inside with each side inward flange 13a from the lower end of each side inward flange 13a, (3) be present in the lower inside of each side bottom 12b and become ground, the obtuse angle bevelled second inclination inward flange 13b2 to the inside with the first inclination inward flange 13b1 from the lower end of each first inclination inward flange 13b1, and (4) are present in the inboard of base 12c and the horizontal base inward flange 13c that the lower end of each second inclination inward flange 1362 links are formed its profile.

The whole longitudinal size of the three banding bag 10-5 that A among Figure 10 represents, what B represented is the whole lateral dimension of three banding bag 10-5.What in addition, BP represented is the side outward flange 14a of three banding bag 10-5 or the intersection point between its extended line and base outward flange 14b or its extended line.IPa represents is intersection point between the side inward flange 13a and the first inclination inward flange 13b1, and IPb represents is intersection point between the second inclination inward flange 13b2 and the base inward flange 13c.Intersection point between the first inclination inward flange 13b1 that IPc represents and the second inclination inward flange 13b2.What a represented is to be the longitudinal size of the intersection I Pa of benchmark with intersection points B P, and what b represented is to be the lateral dimension of the intersection I Pb of benchmark with intersection points B P.What a1 represented is to be the longitudinal size of the intersection I Pc of benchmark with intersection points B P, and what b1 represented is to be the lateral dimension of the intersection I Pc of benchmark with intersection points B P.

In brief, the difference of three banding bag 10-5 shown in Figure 10 is: the inclination inward flange 13b of three banding bag 10-1 shown in Figure 1 is constituted with continuous two lines (13b1,13b2) that constitute the obtuse angle.

In three banding bag 10-5 shown in Figure 10, be that the longitudinal size a of the intersection I Pa of benchmark preferably is in the scope of 0.08A～0.71A with intersection points B P, more preferably be in the scope of 0.15A～0.65A.In addition, be that the lateral dimension b of the intersection I Pb of benchmark preferably is in the scope of 0.12B～0.48B with intersection points B P, more preferably be in the scope of 0.20B～0.40B.In addition, intersection I Pc is positioned at the position than the more close intersection points B P of straight line that links intersection I Pa and intersection I Pb, and, the longitudinal size a1 that with intersection points B P is the intersection I Pc of benchmark is in the scope of 0.01A～0.70A, is that the lateral dimension b1 of the intersection I Pc of benchmark is in the scope of 0.01B～0.47B with intersection points B P.

Described number range is the material particular that can support oneself for the three banding bag 10-5 that make behind the collecting article of taking in liquid and body of powder etc. in incorporating section 13.The scope of the scope of the longitudinal size a of intersection I Pa in the described number range and the lateral dimension b of intersection I Pb is according to the described test results of Fig. 4, be prerequisite promptly: if the longitudinal size of intersection I Pa is in the scope of 0.08A～0.71A with following content, the lateral dimension b of intersection I Pb is in the scope of 0.12B～0.48B, and the snellen test of taking in after liquid and the body of powder etc. is supported oneself.In addition, the scope of the longitudinal size a1 of the intersection I Pc in the described number range and lateral dimension b1 is to select according to test and the test results that the following describes.

In test, the cooresponding three banding bags of combinations of values that are marked with the place of zero mark among identical with the three banding bags that illustrated in the 1st example and kind and Figure 11 have been made.In addition, prepare in the incorporating section 13 of each three bandings bag, to have taken in the snellen test of air being taken out, afterwards the upper end open heat-sealing (sealed width is 5mm) of incorporating section 13 become behind the tap water of 600cc sealing state.

Test method and Fig. 2 and method shown in Figure 3 are identical, the top margin central part that pinches snellen test with finger tip (among the figure ● the position of mark) and on to make this snellen test after carrying be that the place of 50mm utilizes deadweight to drop on this horizontal surface FS from the height H of leaving water plane FS, each sack has been carried out five above-mentioned trials respectively, and by range estimation the state of landing has been estimated respectively.

Test results as shown in figure 11, among the figure-mark represents is the point that can't set intersection I Pc, zero mark is represented be can set intersection I Pc's and the point that can support oneself.

The longitudinal size a1 of Figure 11 is to represent recently that with respect to the percentage of whole longitudinal size A lateral dimension b1 recently represents with the percentage with respect to whole transverse dimension B.The unit of percentum is with 0.05 or 0.04 as base unit, but for the border of-mark and zero mark, then uses the reasonableness of confirming the border than the unit of their little numerical value as required.

In addition, because the longitudinal size a1 of intersection I Pc can not surpass the maxim (0.71A) of the longitudinal size a of intersection I Pc, the lateral dimension b1 of intersection I Pc can not surpass the maxim (0.48B) of the lateral dimension b of intersection I Pb, therefore the maxim with the longitudinal size a1 of intersection I Pc is made as 0.71A, and the maxim of lateral dimension b1 is made as 0.48B.

By test results shown in Figure 11 as can be known, if scope with zero marked, be that the longitudinal size a1 of intersection I Pc is in the scope of 0.01A～0.70A and lateral dimension b1 is in the scope of 0.01B～0.47B, snellen test is supported oneself.But, in described three banding bag 10-5, in order to obtain the first inclination inward flange 13b1 and the second inclination inward flange 13b2, intersection I Pc must be positioned at than linking the position of intersection I Pa with the more close intersection points B P of straight line of intersection I Pb, and therefore actual scope has following condition: be limited to intersection I Pc and be positioned at position than the more close intersection points B P of straight line of binding intersection I Pa and intersection I Pb.

In above-mentioned test, because as what be accommodated in that collecting articles in the incorporating section 13 use is the tap water of difficult self-support in the liquid, therefore, infer also can obtain the result equal with Figure 11 even take in the high liquid of viscosity ratio tap water and flowing power is tested than the body of powder of liquid difference.By the way, the reason that can support oneself of snellen test is as illustrating in the 1st example.

Like this, if adopt three banding bag 10-5 shown in Figure 10, be that the longitudinal size a of the intersection I Pa of benchmark is in the scope of 0.08A～0.71A then by making with intersection points B P, making with intersection points B P is that the lateral dimension b of the intersection I Pb of benchmark is in the scope of 0.12B～0.48B, and make intersection I Pc be positioned at position than the more close intersection points B P of straight line that links intersection I Pa and intersection I Pb, and, making with intersection points B P is that the longitudinal size a1 of the intersection I Pc of benchmark is in the scope of 0.01A～0.70A, making with intersection points B P is that the lateral dimension b1 of the intersection I Pc of benchmark is in the scope of 0.01B～0.47B, and three banding bag 10-5 behind the collecting article of taking in liquid and body of powder etc. in incorporating section 13 are supported oneself.

In addition, what represent among Figure 15 is that each first inclination inward flange 13b1 and each second inclination inward flange 13b2 are provided with the situation that a fold formation portion 15 and each side inward flange 13a are provided with a fold formation portion 16, but plural fold formation portion 15 also can (1) be set on each first inclination inward flange 13b1 and each second inclination inward flange 13b2 and plural fold formation portion 16 is set on each side inward flange 13a, perhaps (2) are only adopted the side in fold formation portion 15 and the fold formation portion 16 and are not adopted the opposing party, perhaps on (3) side in the first inclination inward flange, 1 3b1 and the second inclination inward flange 13b2 fold formation portion 15 is set, perhaps (4) only are provided with one or more fold formation portion 15 on the first inclination inward flange 13b1 of a side and at least one side among the second inclination inward flange 13b2, and perhaps (5) only are provided with one or more fold formation portion 16 on the side inward flange 13a of a side.In a word, if at least one side among side inward flange 13a, the first inclination inward flange 13b1 and the second inclination inward flange 13b2 is provided with fold formation portion, three banding bag 10-5 are supported oneself.

Certainly, fold formation portion same as described above is applied to also can obtain action effect same as described above among three banding bag 10-6 shown in Figure 12, shown in Figure 13 put the palms together before one bag 10-7 and the both sides envelope 10-8 shown in Figure 14.By the way, Figure 16 is applied in situation among the three banding bag 10-6 shown in Figure 12 with fold formation portion same as described above, be provided with at the pars intermedia of each first inclination inward flange 13b1 and make this first inclination inward flange 13b with triangular shaped outstanding to the inside such fold formation portion 15, be provided with in the bottom of each second inclination inward flange 13b2 and make this second inclination inward flange 13b2, be provided with in the bottom of each side inward flange 13a and make this side inward flange 13a with triangular shaped outstanding to the inside such fold formation portion 16 with triangular shaped outstanding to the inside such fold formation portion 15.

[the 2nd variation]

The difference of three banding bag 10-5 shown in Figure 17 (A) and three banding bag 10-5 shown in Figure 15 is: each side bottom 12b is provided with from two folding lines 17 of fold formation portion 15 to the base outward flange 14b of each second inclination inward flange 13b2, and each side bottom 12b is provided with two folding lines 18 from the intersection point between each second inclination inward flange 13b2 and the base inward flange 13c to base outward flange 14b.

Record in " reason that can support oneself " in the explanation of the 1st example, clearly, the influence that the fold that produces in the lower surface of snellen test can bring the self-support of snellen test, therefore, at this, in order on each side bottom 12b of three banding bag 10-5, to form fold respectively energetically, on each side bottom 12b, be respectively arranged with two

folding lines

17,18.

On each side bottom 12b, be respectively arranged with the occasion of two

folding lines

17,18, preferably shown in Figure 17 (B), make adjacent two

folding lines

17,18 towards on the contrary, so that each side bottom 12b is the form bending gallantly of zigzag with the cross section because of each folding line 17,18.In addition, in Figure 17 (B), as folding

line

folding line

17,18 can be by formation simply such as punch process.

According to experiment, if a side folding line 17 and the angle θ 1 that base outward flange 14b constitutes are in the scope of 21 degree～79 degree, and the opposing party's folding line 18 and the angle θ 2 that base outward flange 14b constitutes are in the scope of 51 degree～119 degree, then can form folding line effectively along each

folding line

17,18.

folding lines

17,18 among Figure 17 (A) and Figure 17 (B), but the folding line more than three also can (1) be set on each side bottom 12b, perhaps (2) only are provided with the side in folding line 17 and the folding line 18 on each side bottom 12b, and perhaps (3) only are provided with more than one at least one side in the

folding line

17,18 at the side bottom of side 12b.In a word, be provided with at least one folding line, three banding bag 10-5 are supported oneself as if at least one side among two side bottom 12b.

Certainly, folding line same as described above is applied to also can obtain action effect same as described above among three banding bag 10-6 shown in Figure 12, shown in Figure 13 put the palms together before one bag 10-7 and the both sides envelope 10-8 shown in Figure 14.

[the 3rd variation]

The difference of three banding bag 10-6 shown in Figure 180 and three banding bag 10-6 shown in Figure 16 is: be provided with the triangular shaped fold formation portion 15 bigger than the fold formation portion 15 of three banding bag 10-16 shown in Figure 16 in the bottom of each second inclination inward flange 13b2, and the outward flange of each side bottom 12b1 is provided with recess 19, and this recess 19 is along such triangular shaped of the profile of the fold formation portion 15 that is located at each second inclination inward flange 13b2 bottom.

If such recess 19 is set, even then become big occasion in that the sealed width that makes each side bottom 12b1 because of the relation with the size of fold formation portion 15 is local, also can make the sealed width of each side bottom 12b1 identical on the whole, thus, can realize the minimizing of material cost etc.

Certainly, according to varying in size of fold formation portion, also can on the outward flange of each side bottom 12b1, be provided with fold formation portion 15 corresponding concave part of each first inclination inward flange 13b1 or with fold formation portion 16 corresponding concave part of each side inward flange 13a.

[the 4th variation]

In the 5th～the 8th example, what represent as each first inclination inward flange 13b1 and each second inclination inward flange 13b2 is the edge of linearity, but it is straight straight line that each first inclination inward flange 13b1 and each second inclination inward flange 13b2 need not, and crooked slightly or each the first inclination inward flange 13b1 of each first inclination inward flange 13b1 and each second inclination inward flange 13b2 and each second inclination inward flange 13b2 crawl slightly based on the tolerance of heat-sealing etc. also can obtain action effect same as described above.
