(1/5)×R1≤L1≤(2/3)×R1
And under the situation of L1=0, meaning does not have straight line radial slot 52, and curved slot 54 is formed directly to begin to extend from the center that seals disc-shaped part 34.Therefore, these curved slot 54 are equal to radial component of the present invention and crooked part.In packing 10 according to present embodiment, R1=13mm, and L1=5mm.
Shown in Fig. 4 A, 4B and 5, the width W (seeing Fig. 7 A and 7B) of the upper end by not changing radial slot 52, but (therefore by deep radial slot 52, the angle theta that forms by inclined surface 60 is littler) therefore further reduce the thickness (thickness T 2) of thin part 62, form a low-intensity part 64 at each radial slot 52 of (in scope) in a preset range of the center of sealing disc-shaped part 34 by the indication of the doublet C1 Fig. 4 A.
The thickness T 2 of low-intensity part 64 is set to from being not less than 0.05mm in the scope that is not more than 0.7mm.And thickness T 2 is set so that the thickness L that seals disc-shaped part 34 is 2 or bigger to the ratio (L/T2) of the thickness T 2 of low-intensity part 64.
Shown in Fig. 4 A, curved slot 54 is bent to the shape of a circular arc, with identical direction (being with the clockwise direction among Fig. 4 A in the present embodiment), extends from the most advanced and sophisticated 52A continuation of radial slot 52 with a predetermined radius of curvature and with a predetermined central angle.Each curved slot 54 contacts with a string section 46B (a straight line part) of the thin part 46 of each arc, and little by little extends towards the excircle that seals disc-shaped part 34.
The radius of curvature R 2 of curved slot 54 suitably is determined from viewpoint of punching quality etc.Yet, it is best,
R1/5≤R2
And more preferably,
R1/5≤R2≤R1/2
In packing 10 according to present embodiment, R2=5mm.
Be divided into some small parts if curved slot 54 is considered, in these small parts, do not need to keep radius of curvature R 2 constant.Small separately part can have different radius of curvature R 2 or its part can be become by a linear of the interior part that connects this circular arc, as long as the not loss generally of the smoothness of curved slot 54.
As Fig. 5,6 and 7B shown in, thereby reduce the thickness (thickness T 2) of thin part 62 by deep curved slot 54 tools, do not change the width W of upper end of curved slot 54 and the part place of the intensity of thin part 62 that makes each curved slot 54 sealing disc-shaped part 34 of (among Fig. 4 A outside the indicated scope of doublet C2) outside center one preset range of self sealss disc-shaped part 34 is lower.
Shown in Fig. 7 A and the 7B this is not formed on a part in the inclined surface 60 any, and in this part, curved slot 54 is formed along the arc part 46B of the thin part 46 of arc.Yet also in this part, the thickness of the thin part 46 of arc is that T2 is so that this curved slot 54 is formed in itself.
As shown in Figure 6, the excircle of circumferential groove 56 edge sealing disc-shaped parts 34 is from the extension of the tip of each curved slot 54.The difference of circumferential groove 56 and radial slot 52 and curved slot 54 is the single inclined surface 60 that the surperficial 34A of each circumferential groove 56 by self sealss disc-shaped part 34 extends to rear surface 34B, and is formed by the vertical surface part 46C that the formation arc approaches the circular arc shaped portion 46A of part 46.The thin part 62 that has with the thin part 46 same thickness T2 of arc is formed by circumferential groove 56.Therefore, overview as the groove from Fig. 4 A, 4B and 5 50 is appreciable, center at self sealss disc-shaped part 34 forms low-intensity part 64 in the scope of doublet C1, in this low-intensity part 64, the thickness of thin part 62 is further reduced (thickness T 2).In the scope of doublet C1 and doublet C2, the thickness of thin part 62 is not reduced (thickness T 3) again so that can keep a constant intensity.Outside the scope of doublet C2 indication, the thickness of thin part 62 is reduced (thickness T 2) once more.
Then, will provide the description of a direction and pack the description of 10 operation, wherein in the direction, the photograph processing soup be stopped up the photograph processing medical liquid container 14 of living from its discharge side 18 by packing 10 according to the present invention and is poured out.
In Fig. 8, roughly be illustrated in the photograph processing soup generator 70 in the automatic processing machine.When photograph processing medical liquid container 14 was arranged in the photograph processing soup generator 70, the photograph processing soup was provided from container 14.
For the photograph processing soup is provided into automatic processing machine from photograph processing medical liquid container 14, as shown in Figure 8, at first, photograph processing medical liquid container 14 is inserted in the retaining hole 74 of a holding plate 72 and head is provided with downwards.Under the ventricumbent state of discharge side 18 (see figure 1)s, photograph processing medical liquid container 14 is maintained at a perfusion case (not shown) top.At this moment and since photograph processing medical liquid container 14 discharge side 18 packaged 10 block, the photograph processing soup does not flow out from photograph processing medical liquid container 14.And, as shown in Fig. 9 B, the upper end of a perforated pipe that is provided with in the photograph processing soup generator 70 be positioned in the packing 10 of stopping up discharge side 18 under.
Then, a controller that is not illustrated rotates the miniature gears in the drive part 78 and rises one and raises part 80.Raise the perforated pipe 76 that part 80 is stretched out thereby rise from this, and the point upward roof pressure of perforated pipe 76 stops up the core of the packing 10 of discharge side 18.
Shown in Figure 10 A and 10B, when the center of packing 10 is perforated the point upward roof pressure of pipe 76, near the center of sealing disc-shaped part 34, on fan-shaped part 58, those fan-shaped parts 58 are set on each radial slot 52 (the seeing Fig. 4's) two side portions that forms groove 50 tension force along the directive effect that fan-shaped part 58 is separated from each other.
Usually, when the parts with a fixed thickness when its thickness direction is pressed and disconnect, need be in the starting stage of pushing, i.e. moment before and after the punch on needs maximum pressure (piercing force).In packing 10 according to the present invention, in thin part 62, form low-intensity part 64 at part place, and its intensity is weakened by these the thin parts 62 in the scope of the indication of the doublet among Fig. 4.Therefore, even the hoisting force of perforated pipe 76 is less, in other words, even the rotating torque of the miniature gears of drive part 78 is less, sealing disc-shaped part 34 radially groove 52 is disconnected.That is, available one little pressure branch split the sealing disc-shaped part 34 core near thin part 62.Therefore, can disconnect sealing disc-shaped part 34 along thin part 62.
Shown in Figure 11 A and 11B, when further lifting perforated pipe 76, the crack radially extends to the outside of sealing disc-shaped part 34 along it, and further extends to the thin part 62 (seeing Fig. 4 A) that is formed by curved slot 54.During this fission process, the crack extends to the part (in the doublet C1 and the scope between the doublet C2 among Fig. 4 A) of the thin part 62 that does not form low-intensity part 64 from low-intensity part 64.Yet, at this moment, owing to form the crack in sealing on the disc-shaped part 34, available one little these cracks of pressure extended.
As from Fig. 4 A, seeing, because having with departing from, curved slot 54 do not continue to extend from radially bending groove 52, and be bent with a constant radius of curvature, tension force is along forcing directive effect that fan-shaped part 58 is separated from each other in the fan-shaped part 58 that is arranged on each curved slot 54 both sides.As a result, extend towards the Outboard Sections that seals disc-shaped part 34 smoothly along the radial direction of curved slot 54 in these cracks.
In the thin part 62 that forms by curved slot 54, reduced (thickness T 2) again at thickness, and its intensity is lowered by the part of extraneous each thin part 62 of the doublet among Fig. 4 A indication.Therefore, when fracture extension during, sealing disc-shaped part 34 is disconnected with littler pressure to these low-intensity part.Special in fracture extension during to the string section 46B of the thin part 46 of arc, only the fan-shaped part 58 on a side of each thin part 62 is approached part 46 from arc and is pushed open.Yet even in this case, the crack is expanded along the low-intensity part of the thin part 62 that is formed by curved slot 54, and extends to the thin part 62 that is formed by circumferential groove 56.
When crack during further along slot part 62 expansion, sealing disc-shaped part 34 is disconnected, because thin part 62 (circumferential groove 56) forms along the excircle of sealing disc-shaped part 34, shown in Figure 12 A and 12B, thereby each fan-shaped part 58 is bent at the string section 46B of the thin part 46 of arc.Promptly, as shown in Figure 13, the sealing disc-shaped part 34 be opened and open region made wideer (in contrast, for example, when on sealing disc-shaped part 34, not forming circumferential groove 56, because fan-shaped part 58 is bent along the line of the indication of the doublet C3 shown in Fig. 4 A, the open region of sealing disc-shaped part 34 is made narrower).
Like this, in packing 10 according to present embodiment, on the sealing disc-shaped part 34 of the discharge side 18 that is used to stop up photograph processing medical liquid container 14, form curved slot 54 and circumferential groove 56, this curved slot continues to extend from radial slot 52 nothings with departing from smoothly, and this circumferential groove 56 departs from ground along the excircle that seals disc-shaped parts 34 from curved slot 54 nothings to be continued to extend smoothly.As a result, available little pressure is fully opened sealing disc-shaped part 34.
In packing 10 according to present embodiment, owing to compare with the packing that the intensity of these parts is not lowered, in the low-intensity part 64 that the part place of (in the scope by the indication of the doublet C1 shown in Fig. 4 A) forms in its center one preset range that is formed on the thin part 62 on the sealing disc-shaped part 34, available less pressure disconnects sealing pie-shaped piece 34, thereby and the discharge side 18 of photograph processing medical liquid container 14 is opened.
And because the intensity of the part of the thin part 62 in the scope is not lowered between doublet C1 and doublet C2, sealing disc-shaped part 34 keeps a constant intensity.Therefore, for example because the variation of the internal pressure of photograph processing medical liquid container 14 etc. outwards or are inwardly pushed even seal disc-shaped part 34, sealing disc-shaped part 34 can desirably be disconnected.Special when photograph processing medical liquid container 14 falls, when the internal pressure of container 14 may temporarily raise, yet even in this case, sealing disc-shaped part 34 can not disconnect.
In packing 10 according to present embodiment, because the overall diameter of sealing disc-shaped part 34 is being not less than 0.5cm and is being not more than between the 5cm, because pressure from press device, the sealing disc-shaped part 34 suitably stretch (yet, it can not stretch excessively), available one little pressure disconnects sealing disc-shaped part 34.
As mentioned above, in packing 10, can realize resisting characteristic, promptly in sealing disc-shaped part 34, keep the intensity of a scheduled volume, and can make by the required pressure of press device aperture seal disc-shaped part (being the piercing force of perforated pipe 76) minimum according to present embodiment.
A packing 110 according to a second embodiment of the present invention shown in Figure 14.In this packing 110, compare with packing 10 according to the first embodiment of the present invention, have only the formation difference of the groove in the second embodiment of the present invention.Represent and packing structure division identical in 10 and parts and saving explanation with identical reference number according to first embodiment to them.
In packing 110, shown in Figure 14 A, in four thin part 114A, 114B, 114C and 114D totally being formed by groove 112, the thickness of each two thin part 114A and 114B is less than the thickness of each other two slot part 114C and 114D.That is, thin part 114A and 114B are the thin parts with intensity lower than the intensity of other two thin part 114C and 114D.
Usually, between the required pressure in the length in the crack that forms by the sealing disc-shaped part 116 that is pressed by press device (perforated pipe 76) and this crack of expansion of generating by press device, there is the relation shown in Figure 15 A.The miles of relative movement (according to from most advanced and sophisticated and the contacted point of sealing disc-shaped part, the distance that the tip moved past of perforated pipe 76) of perforated pipe 76 and the relation between the pressure have been shown in the curve of Figure 15 A.Can see that from this curve if four thin parts have identical thickness, in the less stage of distance that perforated pipe 76 moves past, pressure reaches maxim F1 (hereinafter referred to as maximum pressure).At this point, form the crack in thin part.In case on sealing disc-shaped part 34, form the crack, for vee crack only needs a less pressure.Therefore, after pressure surpassed maximum pressure F1, pressure always can reduce.
On the contrary, shown in Figure 15 B when pushing the sealing disc-shaped part 116 of packing 110 by perforated pipe 76 and it is disconnected in the miles of relative movement of perforated pipe 76 and the relation between the pressure.In packing 110,, form the required maximum pressure F2 in crack less than the maximum pressure F1 shown in Figure 15 A at thin part 114A and 114B because the intensity of thin part 114A and 114B is lower than other thin part 114C and the intensity of 114D.And, in the curve of Figure 15 B, can see from the situation that a plurality of maximum pressure values are arranged that pressure acts on four thin part 114A, 114B, 114C and the 114D and spread at different time.
Therefore, when perforated pipe 76 is pushed the center of sealing disc-shaped part 116 of packing 110, at thin part 114A and 114B (low-intensity approaches part) thus go up and form the crack and sealing disc-shaped part 116 is disconnected.When fracture extension during near the part the excircle of sealing disc-shaped part 116, because it is less to form the required pressure in crack at thin part 114A and 114B (seeing Figure 15 B), the crack also extends to other thin part 114C and 114D.Therefore seal disc-shaped part 116 whole disconnections, and discharge side 18 (see figure 1)s are opened.
In four thin part 114A, 114B, 114C and 114D, by making two thin part 114A and 114B be lower than in addition the low-intensity part of two thin part 114C and 114D for its intensity, the tension force that the pressure by press device acts on the fan-shaped part 58 that adjoins each other can be spread at different time.Therefore, available less pressure disconnects sealing disc-shaped part 116.And, be low-intensity part by making two thin part 114A and 114B, at first on thin part 114A and 114B, produce the crack.Therefore, because the thickness of other two thin part 114C and 114D is done relative greatly, can make the thickness of all four thin part 114A, 114B, 114C and 114D bigger.Therefore, even the intensity of sealing disc-shaped part 116 can be held invariable and sealing disc-shaped part 116 inwardly or is outwards pushed with respect to photograph processing medical liquid container 14, sealing disc-shaped part 116 can desirably disconnect.
For the tension force of diffusion on adjacent fan-shaped part 58, need to reduce in a plurality of thin parts two intensity and replace the intensity that the intensity that can make one or three or more thin part is lower than other thin part.And, when (therefore thin number partly is equal to or greater than three, the number of fan-shaped part 58 is equal to or greater than three) time, can realize above-mentioned by forming the effect (tension force that acts on the fan-shaped part 58 is spread at different time) that the thin part of low-intensity obtains.
As shown in Figure 14B, by increasing the angle θ (referring to Fig. 7 A and 7B) that forms by inclined surface 60, can form high strength part 118 in the outside (outside of the scope of doublet C4 indication among Figure 14 A) of center one preset range of self sealss disc-shaped part 116, at these high strength part 118 places, the thickness of thin part 114A, 114B, 114C and 114D is increased.By forming these high strength parts 118, prevent from further to extend in the crack of thin part 114A and 114B formation, and after, the thin part 114C and the 114D that are not formed low-intensity part begin division.When the crack of thin part 114C and 114D arrived high strength part 118, four thin part 114A, 114B, 114C and 114D were caused division at the same time, thereby sealing disc-shaped part 116 is disconnected.
By forming high strength part 118, can prevent only have low intensive thin part 114A and 114B formation crack at four thin part 114A, 114B, 114C and 114D.Can positively form the crack so that sealing disc-shaped part 116 can be disconnected at four thin part 114A, 114B, 114C and 114D.
Packing 130 as one of another example shown in Figure 17 A and the 17B.In this packing 130, in a preset range of 132 of self sealss disc-shaped parts (in scope) by doublet C5 indication, make the thickness of the part in each the thin part 136 that forms by groove 134 bigger by increasing the angle θ (seeing Fig. 7 A and 7B) form by inclined surface 60, thereby and increased its intensity.Therefore, for example compare,, need push sealing disc-shaped part 132 with bigger pressure in the starting stage of aperture seal disc-shaped part 132 with packing 10 according to the first embodiment of the present invention.Yet, in case form the crack in each thin part, and the tip in crack extends to the scope at the extraneous sealing disc-shaped part 132 of being indicated by doublet C5, then makes the crack along its outside that radially extends to sealing disc-shaped part 132 with very little pressure, and sealing disc-shaped part 132 is opened.
In above-mentioned, shown in Figure 18 A, described such example: the inclined surface 60 that wherein forms groove 50,112 and 134 is in contact with one another in their bottom, and each groove 50,112 and 134 forms a shape that is essentially V-arrangement.But groove 50,112 and 134 formation are not limited to this.For example, shown in Figure 18 B, they can form one and be essentially trapezoidal shape, and wherein the bottom 60A of inclined surface 60 does not contact mutually and is separated from each other out.Between the 60A of the bottom of inclined surface 60, form a flat 66 that parallels with the rear surface 34B of sealing disc-shaped part 34.And, can between the 60A of the bottom of inclined surface 60, form the part of a bending, the part of this bending is bent to form one day to the outstanding spill of rear surface 34B.And shown in Figure 18 C, inclined surface 60 can form a rectangular shape perpendicular to the top surface 34A and the rear surface 34B (therefore in fact inclined surface 60 does not tilt) of sealing disc-shaped part 34, and a flat 66 is arranged between the bottom of inclined surface 60.
Partly or partly have low-intensity or high strength structure for wherein approaching part 62,114 and 136, such example of structure has been described: by changing the thickness that the angle θ that is formed by inclined surface 60 increases or reduce thin part 62,114 and 136.But each thin part 62,114 and 136 partly or partly has low-intensity or high strength structure is not limited to this.For example, as mentioned above, being separated from each other a preset distance and each thin part 62,114 and 136 at the bottom of inclined surface 60 60A has under the situation of flat 66 of preset width, each thin part 62,114 and 136 may partly or partly have low-intensity or high strength by the width that changes flat 66, promptly, the width of flat 66 of each thin part 62,114 and 136 is narrower (to comprise the inclined surface 60 that does not have flat 66 therebetween if make, shown in Figure 18 A), tension force is collected in this close limit.Therefore, reduced the integrally stretching of thin part 62, and thin part 62 is easy to division along tension direction.Yet if make the width of flat 66 bigger, because tension force is spread at this relative broad range, thin part 62 increases along the integrally stretching of tension direction, and thin part 62 is difficult for division.
Thin part 62,114 and 136 does not need partly or partly to have low-intensity or senior middle school's intensity and replaces and have constant intensity (thickness T 2 or T4) from sealing disc-shaped part 34 to its excircle.Even in this case, as long as form from the elongated end 52A of radial slot 52 and do not have the curved slot 54 that continuation is extended smoothly with departing from, and continue the circumferential groove 56 that extends as long as form not have along the excircle of sealing disc-shaped part 34 from curved slot 54 with a level and smooth arc, available little pressure is opened fully and is sealed disc-shaped part 34 with departing from.
Thin part 62,114 and 136 can have a constant intensity (constant thickness T4).Even in this case, be set to 2 the mode that is equal to or greater than with ratio (L/T2) with the thickness T 2 of thickness L that will seal disc-shaped part 34 and low-intensity part 64, (L/T4) established to being equal to or greater than 2, thereby available one little pressure is fully opened sealing disc-shaped part 34.
Each groove 50,112 and 134 number are not limited to above-mentioned four.But, even pressure a little less than, for fully open the sealing disc-shaped part 34,116 and 132, the groove number is preferably three or five, and more preferably is four.On the contrary, if the number of groove 50,112 and 134 is six or more, after opening, each seals disc-shaped part 34,116 and closely contacts with press device (perforated pipe 76) with 132 fan-shaped part 58 (seeing Fig. 4 A), and has reduced the gap that forms between each fan-shaped part 58 and press device.On the other hand, if the number of groove 50,112 and 134 is two or still less, then be difficult to open basically sealing disc-shaped part 34,116 and 132.Yet even the groove number is two or still less, so that form a suitable configuration, it respectively is three or five that these grooves can be configured the number that seems groove 50,112 and 134 by crooked these grooves.If form three to five grooves, then do not need to form these grooves diffusely from the center of each sealing disc-shaped part 34,116 and 132 with a fixing central angle.
Do not need groove 50,112 and 134 is formed the shape of continuous straight line, form a series of holes and for example can vertically form discontinuously with integral body along it with preset distance.
Low-intensity part according to the present invention is not limited to groove 50,112 and 134 or form the groove of hole shape.For example, can form a part that can be divided by the pressure of press device by the physical property that changes hermetic unit 34,116 and 132.An example of this situation is a weld bond.When flow out cast gate and near the resin that spreads this cast gate in mould heavy in conjunction with the time, during the injection moulding of a moulded resin products, form a weld bond.That is, in the part that forms weld bond, in many cases, the intensity of resin is lowered.Therefore, position of mold pressing parameter, cast gate etc. should suitably be provided with so that weld bond is formed from the identical shape of the thin part of plan view and these.
As mentioned above, the sealing disc-shaped part is disconnected along a weld bond by forming weld bond, yet, also form groove 50,112 and 134 in position by weld bond, can form packing that the little pressure of a usefulness is opened.
In above-mentioned, an example has been described, wherein form dividually and respectively pack 10,110 and 130 with cap 12.Yet, each can be packed 10,110 and 130 and cap 12 integrally form.Like this, when with each packing 10,110 and 130 and cap 12 when integrally forming, each is packed 10,110 and 130 and can not come off from cap 12.
In above-mentioned, an example of the photograph processing medical liquid container 14 that the photograph processing soup is housed has been described.Yet the present invention is not limited to this and replaces the container that can use any kind.
As the photograph processing soup that holds in the photograph processing medical liquid container 14, for example, can list colour developing solution, black-and-white developer, bleaching liquid, mixed liquor etc.These photograph processing soups are used to handle a photosensitive silve halide material, are to buy and are known.
In above-mentioned,, listed and comprised 50% or more low density polyethylene (LDPE) (LDPE) or 50% or the non-foam resin of more high density polyethylene (HDPE) (HDPE) as the material that forms packing 10,110 and 130.Yet, the invention is not restricted to this naturally and replace chemical resistance by considering to wait to be loaded into the material of container, physical strength etc. and suitably determine material.As mentioned above, use when the photograph processing medical liquid container of photograph processing soup wherein is housed, from the viewpoint of chemical resistance or physical strength, polyethylene is listed as a preferable material.
Especially, comparing by the situation that the resin material that comprises high density polyethylene (HDPE) (HDPE) forms with packing, under the situation that this packing is formed by the resin material that comprises a large amount of low density polyethylene (LDPE)s (LDPE), because this resin self is soft, this packing is easy to stretch.Therefore, available low pressure disconnects the core that respectively seals disc-shaped part 34,116 and 132.And, because the flexibility of resin self, when perforated pipe 76 move past short apart from the time, sealing disc-shaped part 34,116 and 132 core may be in the state of stretching and disconnect.Even in this case, by making perforated pipe 76 move past enough distances, the crack that forms on sealing disc-shaped part 34,116 and 132 radially extends to along it and respectively seals the outside of disc-shaped part 34,116 and 132 and seal disc-shaped part 34,116 and 132 and can be fully opened.And, because the flexibility of resin self, because sealing disc-shaped part 34,116 and 132 is easy to stretch, for example, if photograph processing medical liquid container 14 is fallen, even the internal pressure of container 14 changes, the variation of this internal pressure can be by the sealing disc-shaped part 34,116 that is stretched and 132 absorptions, and can form not open circuited undesirably packing 10,110 and 130.
On the other hand, if compare with 130 situations about being formed by the resin material that comprises a large amount of low density polyethylene (LDPE)s (LDPE) with packing 10,110, packing 10,110 and 130 is formed by the resin material that comprises a large amount of high density polyethylene (HDPE)s (HDPE), and resin self is harder.Therefore, in the starting stage that disconnects sealing disc-shaped part 34,116 and 132, need big pressure.Yet, in case on sealing disc-shaped part 34,116 and 132, form crack (sealing disc-shaped part 34,116 and 132 is disconnected), each integral body that seals disc-shaped part 34,116 and 132 deforms, and piercing force (tension force) acts on the thin part 62 that is made of groove 50.Therefore, even the distance that perforated pipe 76 moves past is shorter, still may open sealing disc-shaped part 34,116 and 132 fully.And, owing to compare with the resin material that comprises a large amount of low density polyethylene (LDPE)s (LDPE), the elasticity of this resin material self is less, when each sealing disc-shaped part 34,116 and 132 is opened, because being difficult to turn back to their residing initial positions before the sealing disc-shaped part is opened, elasticity, fan-shaped part 58 respectively seals disc-shaped part 34,116 and 32 maintenances, one shape of opening.Therefore, because fluid pressure etc. and not reducing in material (photograph processing soup etc.) time of being adorned in discharging this container in a gap that forms between fan-shaped part 58 and the perforated pipe 76 can guarantee the discharging of institute's package material.
Comprise a large amount of intermediate density polyethylenes (MDPE) by use and (have the 0.930 and 0.941 (g/cm that measures with JISK6748-1982
3) between a density range) resin can realize above-mentioned situation.
As mentioned above, 10,110 and 130 the method for unpacking is not limited to photograph processing medical liquid container 14 and is arranged in photograph processing soup generator 70 (see figure 8)s in the automatic developing machine, and packs 10 situations of being pushed by perforated pipe 76.For example, thus packing 10,110 and 130 can push and be opened by article such as bars.
