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

Figure 13 is the first figure of the action for box 20 is described.Figure 14 is for the dynamic of box 20 is described The second figure made.Figure 15 is the 3rd figure of the action for box 20 is described.Additionally, Figure 13～figure 15 is the schematic diagram for illustrating in the way of should be readily appreciated that the state of the inside of box 20.

Before the action of box 20 is illustrated, to making the inside and outside connection of liquid supply department 280 Communication path 310 illustrate.Its one end of communication path 310 is connected entrance 32, the other end It it is air introduction mouth 290.Communication path 310 from connected entrance 32 towards the stream of air introduction mouth 290 End side stream the 33, first communication chamber 242, air chamber is included successively in midway on the flow direction of body 220.End side stream 33 is formed in the stream in liquid supply department 280.Air chamber 220 is lid Space between parts 24 and sheet member 291.

So, box 20 is by including that communication path 310 can suppress liquid supply department 280 interior (in detail For, the part of the existence air comprising opening 288 in liquid supply department 280) pressure with outer The pressure in portion is the most different.

Such as, when box 20 is installed on printer 50 (during installation action), keeper 60 Elastomeric element 648(Fig. 2) enclosed liquid supply department 280 opening 288 around.Here, exist During the surrounding of airtight opening 288, a part for elastomeric element 648 bites into liquid supply department 280 In, the thus volume reducing in liquid supply department 280, the pressure in liquid supply department 280 rises. Usually, from the stream of liquid containing portion 200 to liquid outflow portion 31 in order to avoid flowing out from liquid Portion 31 spills ink to outside and there is the part that flow path resistance is high.In the present embodiment, example As, the sheet member 36 of liquid, foam 34 can be kept to improve by forming the meniscus of liquid Flow path resistance.Therefore, firm by the volume in airtight, liquid supply department 280 around opening 288 Under state after just reducing, the air of the amount of minimizing will not flow fully at liquid containing portion 200 Logical.But it is possible to made the air of the amount of minimizing be discharged to the outside by communication path 310, make outside It is maintained substantially stationary with the pressure in liquid supply department 280.

In the case of assuming to be not provided with communication path 310 on box 20, such as liquid supply department 280 Interior compressed air is flowed into liquid containing portion 200 after box 20 is installed gradually.Thus, at liquid In body receiving portion 200, the air of phase is not given in intrusion, it is possible to cannot make dimension in liquid containing portion 200 Hold in suitable pressure limit.It addition, such as, when the air in liquid supply department 280 is flowed into liquid Body receiving portion 200 is until in the pressure of rising in liquid supply department 280 and liquid containing portion 200 During pressure equilibrium, the rising compared with the state before air inflow of the pressure in liquid containing portion 200. When user in this condition by box 20 in the case of keeper 60 unloads, liquid supply department 280 Interior pressure becomes atmospheric pressure.That is, the pressure in liquid supply department 280 reduces, and ink can be from pressure High liquid containing portion 200 spills to outside via for application component 30.

It addition, such as, under the unused state of box 20, in order to suppress ink to spill to outside, deposit It is installed in the feelings on opening 288 at the seal member (thin film or cap) being used for blocking opening 288 Condition.It addition, under the unused state of box 20, there is box 20 and be accommodated in and be depressurized to compare air Situation in the packaging bag of the pressure forced down.When being mounted with seal member, by box 20 It is contained in packaging bag and to when reducing pressure in packaging bag, air chamber 220 is also depressurized.Then, liquid The absolute value of the negative pressure in receiving portion 200 becomes big (that is, increasingly constituting negative pressure).On the other hand, by It is the space being suppressed the circulation with outside gas in liquid supply department 280, therefore immediately preceding subtracting Atmospheric pressure is maintained after pressure packaging.Thus, the interior pressure with liquid containing portion 200 of liquid supply department 280 Power produces unbalanced, and air is gradually in liquid supply department 280 in influent receiving portion 200.Separately Outward, when taking out box 20 from decompression packaging, air chamber 220 returns to atmospheric pressure, liquid containing The absolute value of the negative pressure in portion 200 also diminishes (negative pressure becoming original setting).On the other hand, liquid The state being depressurized it is maintained in body supply department 280.The most likely from liquid containing portion 200 to liquid Body supply department 280 side leakage goes out ink.

Then, the action to box 20 illustrates.As shown in figure 13, stem valve 44 includes for blocking The valve portion 43 of through hole 47 and for carrying out the bar portion 49 of the opening and closing in valve portion 43.At box 20 not Under use state (state of new product), 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.It addition, helical spring 294 To the direction (+Y direction) of the volume expanding liquid containing portion 200, compression plate 293 is exerted a force.By This, the pressure in liquid containing portion 200 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 compression plate 293 near the 6th During 206 side, face, bar portion 49 is pressed to hexahedro 206 sides by compression plate 293.Thus, valve portion 43 Leaving from through hole 47, outside air temporarily connects with liquid containing portion 200.That is, stem valve 44 becomes For valve opening state.Further, outside air is by air introduction mouth 290, air chamber 220, ventilation Mouth 292, through hole 47 are flowed into liquid containing portion 200.Thus, as shown in figure 15, liquid containing Amount that air is imported into that the volume in portion 200 has become big.Meanwhile, the negative pressure in liquid containing portion 200 is slightly Slightly diminish (close to atmospheric pressure).Further, as shown in figure 15, when importing to liquid containing portion 200 During air to a certain degree, compression plate 293 leaves from bar portion 49.Thus, valve portion 43 is blocked again Through hole 47.That is, stem valve 44 becomes closed valve state.So, when the ink with liquid containing portion 200 When the consumption of water and negative pressure in liquid containing portion 200 become big, stem valve 44 temporarily becomes valve opening shape State, it is possible to maintain in suitable pressure limit the pressure in liquid containing portion 200.
