As shown in Figure 4, ink bag 32 has flexible ink bag 32a, derives the ink lead-out member 32b and the supply opening parts 33 of parts as liquid.Ink bag 32a forms by having flexibility and bubble-tight material, for example, by with two aluminium film overlaies, thermal welding around it etc. method carry out bonding, form therefrom, wherein said aluminium film is the outside with the nylon membrane, be inboard and the double team aluminum constitutes with the polypropylene film.Ink bag 32a also can be that overlapping two flexible films that have that obtain by deposition of aluminum on polyethylene film form.
Ink lead-out member 32b is for example formed by polypropylene, is installed on the ink bag 32a by thermal methods such as (thermal weldings).In detail, when forming described ink bag 32a, with three limits of two overlapping aluminium films by thermal welding carry out bonding after, and with ink lead-out member 32b under the outstanding state that is provided with of the middle body on a remaining limit, it is carried out thermal welding, thereby form ink bag 32.Ink lead-out member 32b is formed by the material of identical quality with the part that ink bag 32a is in contact with one another at least, and from carrying out the viewpoint of heat bonding, this is preferred.
Ink in the ink bag 32a is being held with the state of the degassing.Ink lead-out member 32b roughly is cylindrical shape, and its inside is formed with ink export mouth 32c.By this ink export mouth 32c, take out the ink that is accommodated in the ink bag 32a.In addition, in ink export mouth 32c, be provided with the valve system of only when carrying out ink feed, just opening, make that the ink in the ink bag 32a can not spill.In more detail, the valve system of ink export mouth 32c in a side more inner than supply opening parts 33, is furnished with spring base 34 and helical spring 35 within the ink export mouth 32c of ink lead-out member 32b.Helical spring 35 is pushed spring base 34 to supply opening parts 33 1 sides, and thus, spring base 34 is closed the supply opening 33a of supply opening parts 33.Behind configuration print cartridge 23 on the cartridge seat 12a, the ink feed pin that is formed in the liquid injection apparatus runs through ink supply part 33 and ink lead-out member 32b inside, resists the elastic force of helical spring 35 and spring base 34 is pressed to ink bag 32a one side.After leaving at spring base 34 pressurizeds and from supply opening parts 33, the inks in the ink bag 32 can flow out to the outside from the gap between supply opening parts 33 and the spring base 34.
Therefore, it is constructed as follows.Promptly, in liquid injection apparatus, do not install under the state of print cartridge 23, spring base 34 sealing supply opening 33a, under the state that print cartridge 23 has been installed in liquid injection apparatus, thereby the ink feed pin lifting spring base 34 that is formed on the liquid injection apparatus becomes the state that can supply ink.At this moment, after in ink bag 32, injecting ink, when with ink bag 32 when cartridge case 31 is installed, can be than being easier to grip the ink bag.
The supply opening parts 33 that are disposed at the ink export mouth 32c inside of ink lead-out member 32b are formed by the artificial rubber elastomeric material.Supply opening parts 33 roughly are cylindrical shape, and upper and lower opening, and as shown in Figure 6, thereby the internal face Elastic Contact of the ink export mouth 32c of its outer peripheral face and ink lead-out member 32b is fixed.The inside of supply opening parts 33 is formed with funnel shaped supply opening 33a, with the periphery Elastic Contact that is formed at the liquid supply pin in the liquid injection apparatus.Then, the liquid introducing port that is inserted into the liquid supply pin of supply opening 33a is positioned at the stream 32d of ink lead-out member 32b, thus, will be contained in ink in the ink bag 32a to the liquid injection apparatus supply.In addition, the openend of supply opening parts 33 is retracted into the more inner side of head portion R1 than ink lead-out member 32b (ink export mouth 32c).
Central authorities at the front surface 31e of housing body 31a are formed with foursquare supply opening mounting portion 31f.On the 31f of supply opening mounting portion, be provided with the opening portion 31g that is connected with described inner housing 31d.Then, on the edge of opening of this opening portion 31g, along the outstanding jut R2 that is formed with annular of the direction of this edge of opening towards cartridge case 31 outsides.In addition, on four jiaos of supply opening mounting portion 31f, outstanding be formed with columniform individual bumps part R3, this individual bumps part R3 has the identical overhang with described annular projection part R2 as cartridge case 31 second jut of direction laterally.
In the side of described supply opening mounting portion 31f, be formed with air introducing port H.Air introducing port H is connected outside and the inner housing 31d inside of housing body 31a.When in described cartridge case 31, holding ink bag 32, it is contained among the inner housing 31d, make the ink lead-out member 32b of ink bag 32 expose laterally from the inboard of described opening portion 31g.At this moment, as shown in Figure 6, the ink lead-out member 32b that exposes from opening portion 31g is received into its head portion R1 and is positioned on the extrusion position identical with described annular projection part R2.
After being contained in ink bag 32 in the inner housing 31d, the upper surface 31d1 of this inner housing 31d goes up the first sealing film F1 (with reference to Fig. 4) that thermal is formed by polypropylene.In addition, on the 31f of the supply opening mounting portion of cartridge case 31, thermal the second sealing film F2 that is formed by polypropylene as seal member.In detail, the second sealing film F2 is thermally bonded on annular projection part R2 and the outside outstanding opening portion 31g, simultaneously it is thermally bonded on each individual bumps part R3, wherein said annular projection part R2 is formed at from the edge of opening of the outside opening portion 31g that gives prominence to of supply opening mounting portion 31f.From the viewpoint of thermal (thermal welding), the adhesive surface of the adhesive surface of the adhesive surface of film F 1, cartridge case 31, the adhesive surface of film F 2 and cartridge case 31 is preferably formed by the material of identical quality.
Therefore, after the second sealing film F2 is thermally bonded on the head portion R1 of annular projection part R2 and ink lead-out member 32b, come gap between sealed open part 31g and the ink lead-out member 32d by this second sealing film F2.Consequently, the part except that described air introducing port H all is in sealing state by inner housing 31d that holds ink bag 32 and the film formed space S of sealed thin.Therefore, because inner housing 31d keeps sealing, thereby be fed to air in the inner housing 31d by air introducing port H from being supported on force (forcing) pump 25 (with reference to Fig. 1) on the described framework 12, the ink bag 32 in being contained in space S is exerted pressure.
In addition, owing to the second sealing film F2 is thermally bonded on the head portion R1 of ink lead-out member 32b, thereby the ink export mouth 32c of ink lead-out member 32b is also sealed, and ink bag inside is cut off from the outside.In addition, because the second sealing film F2 and annular projection part R2 thermal, thereby the ink export mouth 32c of ink lead-out member 32b is sealed, does not open spring base 34 thereby do not have from outside insertion thrust, brings bubble in the ink bag problem.In addition, because the second sealing film F2 is thermally bonded on the individual bumps part R3 that surrounds around the annular projection part R2, thereby prevented that the second sealing film F2 is subjected to the effect of some power and is peeled off from annular projection part R2.
In addition, on housing body 31a, clip ink lead-out member 32b and be formed with fixedly floor 31j of two ink lead-out member, the ink lead-out member fixedly end 31j1 of floor 31j contacts with annular projection part 32b1 and is fixed on the housing body 31a, and wherein annular projection part 32b1 becomes disc in the peripheral shape of ink lead-out member 32b.Ink lead-out member 32b is inner mobile to housing body 31a when thus, having limited thermal.
In addition, rotation prevents that parts 31k from being the projection that is meshed with recessed portion (not shown) on the annular projection part 32b1 that is formed at ink lead-out member 32b, and the motion of the direction of rotation of limit ink bag also is located on preposition.
As Fig. 4 and shown in Figure 8, in the present embodiment, above-mentioned inner housing 31d is configured to vacate a little interval with the internal face 126 of shell body 31c.Then, by this at interval, between the internal face 126 of the outside wall surface 127 of inner housing 31d and shell body 31c, form trench portions.In this trench portions, be formed with the first mate K2 (128), make its upper surface (going up direction) opening as the frame shape of first meshing part.
On the other hand, cover 31b forms plate shape, has the size of the opening portion that can cover above-mentioned shell body 31c.On the edge of this cover 31b, the outstanding downwards second tabular mate K1 (130) that is formed with as second meshing part.And this second mate K1 (130) and the above-mentioned first mate K2 (128) are formed with a plurality of accordingly.In addition, the second mate K1 (130) is configured to the size that can be meshed with the above-mentioned first mate K2 (128).Then, be meshed with the first mate K2 (128), and after being installed to this cover 31b on the shell body 31c, just formed print cartridge 31 at the second mate K1 (130) that makes this cover 31b.
So, by in above-mentioned trench portions, forming the first mate K2 (128), in the spatial accommodation that holds ink bag 32 (inner housing 31d), there is not the projection that forms the first mate K2 (128), and the second mate K1 barriers such as (130).Thus, when shell body 31c is matched with cover 31b, can reduce because barrier and bring problem such as unnecessary collision to ink bag 32.
In addition, air introducing port H has been by having disposed the trench portions of the first mate K2 (128), but directly is connected with the space that holds ink bag 31 (inner housing 31d) S.
