Specific embodiment
Next, the specific embodiment that present invention will be described in detail with reference to the accompanying.In addition, use is identical in following figure
Appended drawing reference indicate same or common each section, otherwise will the repetitive description thereof will be omitted and unless especially necessary.
First embodiment
Fig. 1 is the perspective view for showing the first embodiment of flexible container of the invention, and Fig. 2 is Fig. 1 illustrated embodiment
Bottom view.As shown in these figures, the flexible container 1 of present embodiment includes the side wall 12 of the tubular of top fully opened type, has
Towards the charging port 10b of the upward side opening of attached drawing；The bottom surface 15 of generally square shape, is arranged in the opening of downside Yu side wall 12
On the orthogonal direction in direction；And main part 10, have configuration side wall 12 suspension strap support portion 17,17 ....In this reality
It applies in mode, since charging port 10b also serves as outlet, charging port 10b is known as " filling/outlet 10b " herein
(can equally be well applied to the 4th embodiment shown in Fig. 7).
Side wall 12 is the cylindrical body made of soft material, and is provided at the filling/outlet 10b with big
Cause the soft tubular cover 10a of identical peripheral length.Cylindrical body 12 can be seamless, or be also possible to pass through volume
It around a sheet material and engages both ends and is configured to the article of tubular, peripheral length is set to be substantially equal to aftermentioned bottom surface
15 peripheral length.It, can be in addition, it is contemplated that design loading, the flat shape of bottom surface 15 etc. of flexible container of the invention
Suitably set the height of side wall 12.
The soft material of cylindrical body 12 is not particularly limited, can be used conventionally known in chiasma type or sustained
A variety of materials used in container.The former concrete example can enumerate by use loom braiding using flat yarn as warp with
Yarn quality etc. obtained from weft, above-mentioned flat yarn is using the polyolefin resin of polyethylene or polypropylene etc. as raw material.This
Outside, the concrete example of the latter can enumerate ethylene-vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), various rubber, polyethylene
Deng woven fabric etc..These can be suitably used.
The one of the flat shape for the side (2n+2) shape (integer that n value is 1 to 5) that bottom surface 15 is chamfered as each angle
Example, as shown in Fig. 2, being formed as the plane of the substantially quadrangle of the equal chamfering in each angle shape in the arc-shaped of quadrangle (n=1)
Shape is (for convenience, with the outer peripheral portion that symbol 15a indicates to carry out chamfering to the angle and is formed.).In addition, bottom surface 15 passes through
Suture, bonding, the methods of fusion are joined to the open end of a side of side wall 12, also, with the opening direction of closed side wall 12
The mode of one end configures on the direction orthogonal with the opening direction.
In view of the raising of the design loading and charging efficiency of the flexible container of present embodiment, will usually be fallen by this
The total length for the outer peripheral portion 15a that angle is formed is about 20~62% relative to the ratio set of the peripheral length of bottom surface 15.At this
In the case where the flexible container of embodiment, for example, can be obtained based on following design.It is assumed that the plane of the bottom surface 15 before chamfering
Shape be on one side be the square of 1050mm, and assume the side being divided into 3,4,6 and 8 parts.Then, in each case
Under in obtained 9,16,36 and 64 grids, only the both sides (periphery) in the outside of the grid at four angles for being located at bottom surface are held
Row chamfer machining forms circle-arc profile.It is assumed that chamfering carried out to each angle and the outer peripheral portion that is formed is quadrant, then four
The total length of the outer peripheral portion at angle is the length of circumference.On the other hand, the complete cycle length of bottom surface can be by adding up to the circumference
Length and the total length of linear outer peripheral portion obtain.For example, the case where each side of bottom surface 15 is divided into three parts
Under, the length of the peripheral part 15a formed by chamfering is 2198mm, and the complete cycle length of bottom surface is 3598mm, therefore, above-mentioned ratio
It is 61.1%.In addition, in the case where each side of bottom surface 15 is divided into four parts, the outer peripheral portion 15a's that is formed by chamfering
Length is 1649mm, and the complete cycle length of bottom surface is 3749mm, and therefore, above-mentioned ratio is 44%.Similarly, it is divided into Jiang Gebian
Ratio in the case where 6 parts is 28.2%, and the ratio in the case where Jiang Gebian is divided into 8 parts is 20.7%.When into one
Step is when fine equal part makes above-mentioned ratio become smaller, and the flat shape of bottom surface 15 is close to quadrangle, and then the flexibility of present embodiment
The size for being closely sized to the pallet placed by it of the cross section of container, therefore, although charging efficiency is ideal, when from top
When observation, due to the expansion of main body, the part of the side wall 15 except part corresponding with each angle of bottom surface 15 is likely to from support
Disk is prominent.In addition, generating the space for being difficult to fill content near each angle of bottom surface 15, as a result, lead when filling content
Cause the reduction of charging efficiency.On the contrary, the flat shape of bottom surface 15 is circle in the case where less than three equal parts are for example divided into two parts
Shape (cross-sectional shape of side wall is round), because the relationship idle space with pallet becomes larger, thus is not preferred.
In addition, showing the form by the equal chamfering in each angle of bottom surface for circle-arc profile in fig. 1 and 2, but fall
Angular shape is without being limited thereto, such as can be elliptical shape or parabolic shape.In addition, other than this continuous peripheral shape,
It is also possible to repeatedly be arranged parallel to the interrupted peripheral shape of multiple buckling portions of the opening direction of side wall 12.In addition, bottom
Face 15 can be by constituting (sometimes referred below as bottom surface material) with 12 identical type of side wall or different types of plate.Separately
Outside, the flat shape of bottom surface 15 is not limited to Fig. 1 and substantially quadrangle form shown in Fig. 2, is also possible to above-mentioned to passing through angle
The substantially hexagon (n=2) of progress chamfering, substantially octagon (n=3), substantially decagon (n=4) and substantially dodecagon
(n=5).
In side wall 12, in each part 12a, 12a, 12a, 12a, (for convenience, referred to as " angle corresponds to band for the part
Portion ".) on be mutually set in parallel two first reinforcement band portions 13,13 (on the opening direction of side wall 12), wherein it is above-mentioned
Part 12a, 12a, 12a, 12a are parallel to its opening direction and in band-like, and have be joined to outer peripheral portion 15a, 15a,
The end of 15a, 15a, in addition, the outer peripheral portion 15a, 15a, 15a, 15a are to pass through in the bottom surface side of side wall 12 to bottom surface 15
Each angle carries out chamfering and is formed.Each first reinforces band portion 13 can be by the peripheral part with its end included in bottom surface 15
Point mode or by from outer peripheral portion 15a to it is circumferential it is outstanding in a manner of engaged.The reason is that first reinforces band portion 13
Bonding station largely by angle chamfering shape/size (pass through chamfering formed outer peripheral portion shape and ruler
It is very little) or first reinforce band portion 13 width etc. influence.Particularly, first reinforces band portion 13 so that the end of its bottom surface side is from outer
Partly mode outstanding engages circumferential portion 15a, that is, is preferably configured at least one portion of the width direction of the end
It is joined to outer peripheral portion 15a, remainder is from outer peripheral portion 15 to circumferential prominent.Like this,
The reinforcement mode of each first reinforcement band portion 13 is not particularly limited.For example, can by by identical type or
Different types of plate sutures, merges, being adhered to surface or the inside of side wall 12 to reinforce.Therefore, first reinforce band portion 13 to
(especially tensile strength is special for few strength characteristics on the opening direction of side wall 12 or circumferential direction improved along the surface of side wall 12
Property), so that the first reinforcement band portion 13 is suppressed in the elongation of above-mentioned all directions.In addition, making in the case where above-mentioned yarn quality
Reinforce form for another kind, the first reinforcement band portion 13 can also be reinforced by increasing flat textile filament yarn.By that will configure
The quantity of the warp of the opening direction for being parallel to side wall 12 in the width that first reinforces band portion 13 is compared to the first reinforcing strip
The quantity of warp in the same widths of side wall 12 except portion 12 is relatively increased, and by the increased amount in above-mentioned width
The warp of overlapping is woven into the weft on the direction in the above-mentioned direction for being orthogonal to side wall 12 after being dispersed in degree and forms the
One reinforces band portion 13.In addition, in above-mentioned yarn quality, it, can also be by making to match as the reinforcement mode increased except braiding
The width of warp set in the first reinforcement band portion 13 narrows, so as to be inserted into weft and without multi-layer braided, to increase each
The quantity of the warp of the width, or can be reinforced by relatively increasing its thickness compared to the thickness of weft,
Rather than increase the quantity of warp of the configuration in the first reinforcing strip 13.Each first reinforces the circumferential direction of the side wall 12 of band portion 13
Width can carry out setting appropriate according to its form.For example, when by increasing the flat yarn for weaving the former to reinforce,
The width of first reinforcement band portion 13 is typically set at 50~200mm, it is preferred that the warp that will be configured in the width being set
Quantity relative increase of the line number amount compared to the warp configured in the same widths of the side wall 12 except the first reinforcement band portion 13
30% to 100%, by by increased quantity dispersed in above-mentioned width after the warp of overlapping is woven into weft overlapping
To form the first reinforcement band portion 13.It is less than above range by the ratio set of warp quantity, so that side wall 12 is difficult to keep bottom
The shape in face 15.As described above, be reinforced by increasing braiding first reinforces band portion 13, the table along side wall 12 is at least improved
Strength characteristics (especially tensile strength characteristics) of the face on the opening direction of side wall 12, so that first reinforces band portion 13 above-mentioned
Elongation in all directions is suppressed.
As described above, showing each two first reinforcements band portion 13,13 in the example of fig. 1 is joined to each of bottom surface 15
The construction of the outer peripheral portion 15a at angle, it may, however, also be for example each one first reinforcement band portion 13, which is arranged, corresponds to band at each angle
The construction of portion 12a.Each angle can be suitably set in and correspond to two or more first reinforcement band portions of the middle setting of band portion 12a
13 or only be arranged one.
As described above, first reinforces band portion 13 in the case where bottom surface 15 has the flat shape of above-mentioned hexagon or more
It can be set at all or part of corresponding position with the outer peripheral portion 15a at each angle of bottom surface 15 in side wall 12.
Here, the case where being arranged at a part of corresponding position with angle refers to, for example, the configuration suspension strap in side wall 12 supports
Band portion 13 is reinforced in setting first at the position in portion 17.That is, even if the flat shape in bottom surface has the planar shaped of hexagon or more
In the case where shape, as long as each outer peripheral portion 15a, 15a, 15a, 15a at least four jiaos wherein are respectively provided with the first reinforcement
Band portion 13,13,13,13.
The both ends of band-like suspension strap support portion 17 are sewn to respectively in two first adjacent reinforcement band portions 13, so that will
They are bridged in the position close to its charging port 10b, also, middle section is formed towards the U-shaped of falling of the side charging port 10b extension
Shape.The material for example with aftermentioned 18 identical type of suspension strap can be used in the suspension strap support portion 17.
Suspension strap 18 is formed as annular and its both ends is turned back and is sewn to the intermediate region of the band, and should
Annular end 18a is attached to suspension strap support portion 17.Also, both ends (ring end) 18a, 18a of suspension strap 18 is attached to configuration respectively
Suspension strap support portion 17,17 at position corresponding with the two of bottom surface 15 angles, in addition, other suspension strap 18 is attached to and matches
Set the suspension strap support portion 17,17 at position corresponding with other two angle.As the material of suspension strap 18, can be used
