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

Figure 14 is the first figure of the action for illustration of box 20.Figure 15 is the second figure of the action for illustration of box 20.Figure 16 is the 3rd figure of the action for illustration of box 20.In addition, Figure 14 ~ Figure 16 is the schematic diagram be easy-to-understand to illustrate for the state of the inside by box 20.

Before the action that box 20 is described, be described with outside communication path 310 being communicated with in liquid supply department 280.One end of communication path 310 is connected entrances 32, and the other end is air introduction mouth 290.Communication path 310, from connected entrance 32 on the flow direction of the fluid of air introduction mouth 290, has end side runner 33, first communication chamber 242, air chamber 220 on the way wherein successively.End side runner 33 is formed in the runner in liquid supply department 280.Air chamber 220 is the spaces between cover 24 and sheet member 291.

As mentioned above, box 20, by possessing communication path 310, can suppress the pressure of (specifically, comprising the part that there is air of opening 288 in liquid supply department 280) in liquid supply department 280 extremely different from outside pressure.

Such as, when to (during installation action) during printer 50 mounting box 20, the opening 288 of elastomeric element 648 (Fig. 2) the seal fluid supply department 280 of retainer 60 around.At this, when the surrounding of sealed open 288, get in liquid supply department 280 for one by elastomeric element 648, the volume reducing in liquid supply department 280, the pressure increase in liquid supply department 280.Usually, there is the high part of flow passage resistance force of waterproof from the runner of liquid containing portion 200 to liquid outflow portion 31 to make ink not leak into outside from liquid outflow portion 31.In the present embodiment, such as, form the meniscus of liquid, by keeping sheet member 36, the sponge 34 of liquid, flow passage resistance force of waterproof uprises.Thus, sealed around opening 288, under the state after the volume in liquid supply department 280 has just reduced, the air of the part of minimizing can not fully be passed to liquid containing portion 200.But, the air of the part of minimizing can be discharged to the outside by communication path 310, the pressure in outside and liquid supply department 280 can be maintained roughly fixing.

Suppose not arrange communication path 310 on box 20, then the compressed air in such as liquid supply department 280 is after box 20 is installed gradually in influent accommodation section 200.Thus, do not have the air expected to invade in liquid containing portion 200, likely cannot maintain suitable pressure limit by liquid containing portion 200.In addition, such as, when the air influent accommodation section 200 in liquid supply department 280 until pressure balance in the pressure of rising in liquid supply department 280 and liquid containing portion 200 time, rising compared with state before the pressure in liquid containing portion 200 and air flow into.User has taken off box 20 from retainer 60 in this condition, the pressure in liquid supply department 280 has become atmospheric pressure.That is, the pressure in liquid supply department 280 reduces, and ink externally leaks from the liquid containing portion 200 that pressure is high via for application component 30.

In addition, such as, under the unused state of box 20, in order to suppress ink leakage to outside, sometimes the lid (film or cap) being used for blocking opening 288 is installed to opening 288.In addition, under the unused state of box 20, box 20 is accommodated in the packaging bag being decompressed to subatmospheric pressure sometimes.Under the state being provided with lid, when box 20 to be contained in packaging bag and to when reducing pressure in packaging bag, air chamber 220 is also depressurized.So the absolute value of the negative pressure in liquid containing portion 200 becomes large (that is, becoming negative pressure further).On the other hand, owing in liquid supply department 280 being the space of circulation of the gas that inhibit between outside, therefore after just decompression packaging, atmospheric pressure is maintained.Thus, with the pressure imbalance of liquid containing portion 200 in liquid supply department 280, air is gradually from influent accommodation section 200 in liquid supply department 280.In addition, when taking out box 20 from decompression packaging, atmospheric pressure got back to by air chamber 220, and the absolute value of the negative pressure in liquid containing portion 200 also diminishes (negative pressure becoming original setting).On the other hand, maintain the state be depressurized in liquid supply department 280, thus, likely ink leaks from liquid containing portion 200 to liquid supply department 280 side.As mentioned above, the ink leaking into liquid supply department 280 side likely enters connected entrance 32, and is externally leaked from air introduction mouth 290 by communication path 310.

Next, the action of box 20 is described.As shown in figure 14, stem valve 44 comprises: for blocking the valve portion 43 of through hole 47 and the bar portion 49 for the switch that carries out valve portion 43.Under the unused state (new product state) 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 clogs through hole 47.In addition, helical spring 294 exerts a force to the direction (+Y direction) of the volume expanding liquid containing portion 200 to compression plate 293.Thus, the pressure in liquid containing portion 200 is maintained subatmospheric pressure (negative pressure).

As shown in figure 15, when the ink of liquid containing portion 200 be consumed, compression plate 293 close to the second 202 side, face time, bar portion 49 presses to the second side, face 202 by compression plate 293.Thus, through hole 47 is left in valve portion 43, and outside air is temporarily communicated with liquid containing portion 200.That is, stem valve 44 becomes valve opening state.Then, outside air is by air introduction mouth 290, air chamber 220, blow vent 292, through hole 47 influent accommodation section 200.Thus, as shown in figure 16, the volume of liquid containing portion 200 increases the amount that air is imported into.Meanwhile, the negative pressure in liquid containing portion 200 diminishes a little (close to atmospheric pressure).Further, as shown in figure 16, once air is to a certain degree directed in liquid containing portion 200, then compression plate 293 leaves bar portion 49.Thus, through hole 47 is blocked in valve portion 43 again.That is, stem valve 44 becomes close valve state.As mentioned above, along with the consumption of the ink of liquid containing portion 200, when the negative pressure in liquid containing portion 200 becomes large, stem valve 44 temporarily becomes valve opening state, the pressure in liquid containing portion 200 can be maintained in suitable pressure limit thus.

Cap described later is installed on box 20.Be mounted by cap, liquid supply department 280 is capped, and inhibits ink to leak from liquid supply department 280.At this, when taking out box 20 as described above from packaging bag, the ink leaked out from liquid supply department 280, likely arrive air introduction mouth 290 by communication path 310 because of collision when transporting from the ink that liquid supply department 280 leaks out, thus externally leak.But, by cap described later is installed to box 20, even if when ink externally leaks, also inhibits ink to the attachment of prism unit 270 (through face 275) and ink from air introduction mouth 290 to the diffusion of Z-direction.
