A-5. the action of communication path and box 20：

Figure 13 is the first figure for illustrating the action of box 20.Figure 14 is the second figure for illustrating the action of box 20.Figure 15 is the 3rd figure for illustrating the action of box 20.Additionally, Figure 13~Figure 15 is for should be readily appreciated that the shape of the inside of box 20 The schematic diagram that the mode of state is illustrated.

Before the action to box 20 is illustrated, the communication path to making the inside and outside connection of liquid supply department 280 310 illustrate.The one end of communication path 310 is connected entrance 32, and the other end is air introduction mouthful 290.Communication path 310 Including one end effluent road 33, the successively in midway from connected entrance 32 towards on the flow direction of the fluid of air introduction mouthfuls 290 One communication chamber 242, air chamber 220.One end effluent road 33 is formed in the stream in liquid supply department 280.Air chamber 220 is lid Space between part 24 and sheet member 291.

In this way, box 20 can suppress in liquid supply department 280 (specifically, liquid supply by including communication path 310 The part of the presence air comprising opening 288 in portion 280) pressure from outside pressure it is terrifically different.

For example, when box 20 is installed on printer 50 (during installation action), (figure of elastomeric element 648 of retainer 60 2) around the opening 288 of enclosed liquid supply department 280.When here, around closed opening 288, the one of elastomeric element 648 Part is bitten into liquid supply department 280, thus the volume reducing in liquid supply department 280, the pressure in liquid supply department 280 Rise.Usually, from liquid containing portion 200 to the stream of liquid outflow portion 31 in order to avoid from liquid outflow portion 31 to outside leakage Go out ink and there is flow path resistance part high.In the present embodiment, for example, can be protected by forming the meniscus of liquid Hold the sheet member 36 of liquid, foam 34 and improve flow path resistance.Therefore, by closed, liquid supply department around opening 288 Volume in 280 just reduce after in the state of, the air of the amount of reduction will not fully circulate in liquid containing portion 200. The air of the amount of reduction is discharged to the outside but it is possible to pass through communication path 310, is made in outside and liquid supply department 280 Pressure is maintained substantially stationary.

Assuming that in the case of being not provided with communication path 310 on box 20, such as being compressed in liquid supply department 280 Air is flowed into liquid containing portion 200 gradually after the installation of box 20.Thus, invaded in liquid containing portion 200 and do not give the phase Air, it is possible to cannot make to maintain appropriate pressure limit in liquid containing portion 200.In addition, for example, working as liquid supply department Air in 280 is flowed into liquid containing portion 200 until the pressure and liquid containing portion 200 of the rising in liquid supply department 280 When interior pressure is balanced, the pressure in liquid containing portion 200 rises compared with the state before air inflow.When in this condition In the case that user unloads box 20 from retainer 60, the pressure in liquid supply department 280 is changed into atmospheric pressure.That is, liquid is supplied Answering the pressure in portion 280 reduces, and ink can spill via for application component 30 from pressure liquid containing portion 200 high to outside.

In addition, for example, under the unused state of box 20, being spilt to outside to suppress ink, existing for blocking out The seal member (film or cap) of mouth 288 is installed in the situation on opening 288.In addition, under the unused state of box 20, depositing Situation about being depressurized in the packaging bag of the pressure forced down than air is accommodated in box 20.When being mounted with the shape of seal member Under state, box 20 is contained in packaging bag and during to being depressurized in packaging bag, air chamber 220 is also depressurized.Then, liquid containing portion The absolute value of the negative pressure in 200 becomes big (that is, increasingly constituting negative pressure).On the other hand, due to being suppressed in liquid supply department 280 With the space of the circulation of outside gas, therefore atmospheric pressure is maintained after decompression packaging.Thus, liquid supply department 280 The pressure generation of interior and liquid containing portion 200 is unbalanced, and air is gradually from influent receiving portion 200 in liquid supply department 280 It is interior.In addition, when box 20 is taken out from decompression packaging, air chamber 220 returns to atmospheric pressure, the negative pressure in liquid containing portion 200 Absolute value also diminish the negative pressure of setting (turn into original).On the other hand, it is maintained the shape being depressurized in liquid supply department 280 State.Thus it is possible to go out ink to the side leakage of liquid supply department 280 from liquid containing portion 200.

Then, the action to box 20 is illustrated.As shown in figure 13, stem valve 44 includes the valve portion for blocking through hole 47 43 and for carrying out the bar portion 49 of the opening and closing of valve portion 43.Under the unused state (state of new product) of box 20, liquid containing Portion 200 is full of by ink.In this condition, the valve portion 43 of stem valve 44 is exerted a force by spring members 42 and blocks through hole 47.In addition, spiral shell Rotation spring 294 exerts a force to the direction (+Y direction) of the volume for expanding liquid containing portion 200 to compression plate 293.Thus, liquid holds The pressure in portion 200 of receiving is maintained at the pressure (negative pressure) forced down than air.

As shown in figure 14, when the ink of liquid containing portion 200 is consumed and compression plate 293 is close to the 6th 206 side of face, receive Bar portion 49 is pressed to the side of the 6th face 206 by pressing plate 293.Thus, valve portion 43 is left from through hole 47, outside air and liquid containing Portion 200 temporarily connects.That is, stem valve 44 turns into valve opening state.Also, the air of outside is by air introduction mouthful 290, air chamber 220th, blow vent 292, through hole 47 are flowed into liquid containing portion 200.Thus, as shown in figure 15, the volume of liquid containing portion 200 becomes The amount that big air is imported into.Meanwhile, the negative pressure in liquid containing portion 200 diminishes (close to atmospheric pressure) slightly.Also, such as Figure 15 Shown, when air to a certain degree is imported to liquid containing portion 200, compression plate 293 leaves from bar portion 49.Thus, valve portion 43 Through hole 47 is blocked again.That is, stem valve 44 turns into closed valve state.In this way, working as the liquid with the consumption of the ink of liquid containing portion 200 When negative pressure in body receiving portion 200 becomes big, stem valve 44 temporarily becomes valve opening state, thus, it is possible to by liquid containing portion 200 Pressure is maintained in appropriate pressure limit.

When sheet member 36 and liquid supply tube 640 are contacted, sheet member 36 is stressed from liquid supply tube 640. Due to the power, there is situation about sustaining damage in sheet member 36.Specifically, there is breakage, the deformation for producing sheet member 36 The situation of equivalent damage.Because user repeats to be loaded and unloaded box 13,13a, 13b, 20,20a relative to retainer 60, therefore the damage Wound becomes notable.In to the box 13,13a, 13b, 20, the 20a that generate damaged, deformation equivalent damage sheet member 36 again During filling ink, there is the situation of the undesirable condition for producing following.For example, being spilt in the presence of the damaged position from sheet member 36 The situation of ink.In addition, for example, because bubble invades to the end 54 from the position of deformation, have first 54 and produce and spray the feelings such as bad Condition.

Therefore, when to being regenerated using complete box 13,13a, 13b, 20,20a, it is considered to change sheet member 36.

But, sheet member 36 due to being installed to supply department's main body 285 by deposition etc., therefore, it is difficult to change.

Therefore, in the 5th implementation method, regenerated for being changed without sheet member 36 box 13,13a for having used, 13b, 20th, the method for 20a is illustrated.

Figure 26 H are exaggerated near the liquid supply department 280 of box 20b (the box 20b being reproduced) of the 5th implementation method Figure.It is to be constituted with above-mentioned box 13,13a, 13b, 20,20a identicals in addition to the composition of liquid supply department 280.Such as following theory As bright, the box 20b being also reproduced referred to as regenerating box 20b.

As shown in Figure 26 H, the liquid supply department 280 of the 5th implementation method passes through piece in the state of sheet member 36 is remained The covering of material part (thin film component) 93 opening 288.That is, sheet member 93 to cover opening 288 in the way of very close to each other pass through Deposition etc. is airtightly arranged on the other end 37a.Difference with the sheet member 92,94 of Figure 27 described later is：Relatively Formed by the way that the material of liquid can not be passed through in sheet member 92,94, the sheet member 93 of the 5th implementation method passes through can be saturating The material for crossing liquid is formed.Contacted with liquid supply tube 640 by making at least a portion of sheet member 93, ink can be made to exist Circulated in first 54.Here it is possible in the state of at least a portion of sheet member 93 is contacted with sheet member 36 sheet member 93 by cover opening 288 in the way of be installed on the 37a of the other end.Thus, ink is from sheet member 36 to sheet member 93 Circulation, can well supply ink via sheet member 93 to printer 50.In addition, sheet member 93 has pliability, can Contacted with sheet member 31 so that the sheet member 93 under the installment state of box 20b is pressed into by liquid supply tube 640.Additionally, In Figure 26 H, connected entrance 32 is also blocked by sheet member 95, but can not also be blocked.In the case where blocking, can be and piece The identical material of material part 93, or with the sheet member 92 shown in Figure 27,94 identical materials.It is open for covering 288 sheet member 93 preferably is configured to form the meniscus based on liquid (ink).By in this way, will not Box 20b is installed in the state of printer 50, can reduce the possibility that ink escapes to outside from sheet member 93.In regeneration In box 20b, sheet member 93 turns into for making ink flow to the liquid outflow portion 31 of outside (liquid supply tube 640).

E-2. effect：

In the above-described embodiment, even due to use etc. before the regeneration in box 13,13a, 13b, 20,20a when It is engraved in and generates breakage in the sheet member (thin film component) 36 of function as liquid outflow portion 31, deforms equivalent damage In the case of, it is also possible to be changed without using complete box 13,13a, 13b, 20, the sheet member 36 of 20a and liquid outflow portion is newly set 31.Thereby, it is possible to simply regenerating box 20b.

F. the 6th implementation method：

F-1. the renovation process of box：

6th implementation method is to the renovation process using complete box and has regenerated the regeneration of the box for having used and gained Box is illustrated.

Figure 26 I are the figures for illustrating regenerating box 20c.Figure 26 I are the figures suitable with Figure 16.The regeneration of the 6th implementation method The difference of the box 20 (Figure 16) of box 20c and first embodiment is following point.That is, relative in first embodiment Connected entrance 32 is formed with box 20, and is sealed or covering connected entrance 32 by parts such as sheet member 95a in regenerating box 20c Point on it is different.Constituted due to being same composition with first embodiment for others, therefore marked for same composition Same-sign is simultaneously omitted the description.Sheet member 95a is formed by being not through the material of liquid.

As explained above, connected entrance 32 also functions to following functions：For preventing because holding under reduced pressure by box 20 The unbalanced ink for causing of pressure assumed in the case of being contained in packaging bag spills.

On the other hand, in recent years, there is provided reclaimed to consider environment etc. using after complete box by refilling Ink is come the box after regenerating the method for the box for having used and regenerating.

Such regenerating box is from the point of view of the viewpoints such as environment are considered in the presence of situation about being sold in not being accommodated in packaging bag. Further, since ensure the degassing degree of ink or cut down the reason such as cost, although exist be accommodated in packaging bag be not It is received under decompression and sells the situation of box.For such regenerating box, due to the ink caused because foregoing pressure is unbalanced The possibility that water spills generation is low, therefore in the viewpoint that the unbalanced ink for causing because of pressure spills, connected entrance 32 is not played Its function.In addition, connected entrance 32 with air introduction mouthfuls 290 due to connecting, thus into connected entrance 32 ink be possible to from Air introduction mouthful 290 spills.

Therefore, the regenerating box 20c of the box 20 for having been used for regeneration, preferably connected entrance 32 is sealed or covered. That is, preferably block between the outside of connected entrance 32 and the inside (specifically, second flow path 39) of liquid supply department 280 The circulation path of fluid.Here, so-called fluid at least represents liquid.

There are following various methods as the method for sealing or covering connected entrance 32.For example, as a side Method, as shown in Figure 26 I, there is the method that connected entrance 32 is sealed by sheet member 95a.For example, as another method, having to bag The method that path 33 containing connected entrance 32 fills up resin etc..In addition, for example having to block connected entrance as other methods Method of 32 mode to the deposition resin of connected entrance 32 etc..In addition, for example, as other methods, thering is deposition to divide shape The method for blocking connected entrance 32 into the part itself (around connected entrance 32, connected entrance forms part 32t) of connected entrance 32. That is, for regenerating box 20c, the connected entrance 32 being formed on box 20 is sealed or covered, or, as long as path 33 is blocked for i.e. Can, the method for cutting of the circulation paths such as its encapsulating method, covering method, occlusive method can not be considered.

Additionally, resin used when sealing or covering connected entrance 32 etc. or the connected entrance for being sealed or being covered 32 preferably compare not (288 sides of opening) laterally with sheet member 36 protrudes.That is, because：In regenerating box 20c, when used for (288 sides of opening) are prominent laterally compared with sheet member 36 for the part or connected entrance 32 for blocking circulation path and using itself When, due to other component contacts such as cap 70,70a, 70b, 70c, liquid supply tube 640, elastomeric element 648, it is possible to it is right Other parts cause to damage.

F-2. effect：

When the complete box 20 of the use that regeneration is formed with connected entrance 32, can be suppressed in keeping again by blocking circulation path Ink is spilt to outside from air introduction mouthful 290 during raw box 20c etc..

In addition, when sealing or covering connected entrance 32 part such as resin for using or sealed by the part or The connected entrance 32 of covering is with sheet member 36 than (288 sides of opening) are not prominent laterally.Thereby, it is possible to suppress due to cap 70, The miscellaneous parts such as 70a, 70b, 70c, liquid supply tube 640, elastomeric element 648 contact and miscellaneous part are caused to damage.

F-3. the variation of the 6th implementation method：

In the 6th implementation method, when the box 20 that regeneration has been used, sealed by resin etc. or covering connected entrance 32 To block circulation path.According to other variations, the resin etc. also may be used for blocking the part (blocking part) of circulation path To be configured to be removed when user uses.That is, preceding time point is used in user, because connected entrance 32 is sealed or is covered, Therefore can suppress in keeping regenerating box 20c from 290 leak inks of air introduction mouthful being connected with connected entrance 32.The opposing party Face, part is blocked by being unloaded when user will use, and the inside and outside of liquid supply department 280 is connected by connected entrance 32. Thereby, it is possible to suppress because the regenerating box 20c that will be installed on retainer 60 from retainer 60 unload when etc. producible pressure not Ink leakage caused by balanced.

G. the 7th implementation method：

G-1. the renovation process of cap 70b, 70c：
