With reference to the accompanying drawings, print cartridge 1 comprises ink sac 2 that is filled with China ink and the housing 3 that holds ink sac 2.Housing 3 comprises first housing parts 11, second housing parts 12 and the 3rd housing parts 13, and wherein first housing parts 11 and second housing parts 12 form the housing parts of the protective cover that act as protection ink sac side together.Therefore, the housing 3 that holds ink sac 2 is divided into first housing parts 11 and second housing parts 12 along the plane parallel with ink supply direction (going out black direction).
At first, with reference to figure 5-13 the example of ink sac 2 of the present invention is described, wherein Fig. 5 is the side view of same ink sac, and Fig. 6 is the view that shows the ink sac of the Fig. 5 that sees from backward directions, and wherein ink sac is filled with China ink; Fig. 7 is the cutaway view of aluminium lamination film that constitutes the capsule main body of ink sac, Fig. 8 is the side view that shows the ink sac supporting member, Fig. 9 is the view that shows the supporting member of Fig. 8 from the rear, Figure 10 is the view that shows the supporting member of Fig. 8 from the place ahead, Figure 11 is the cutaway view that shows the discharging opening for permitting discharging of the toner of ink sac, Figure 12 is the cutaway view that shows the cup member that is set to discharging opening for permitting discharging of the toner, and Figure 13 is the view that shows the cup member of seeing from its place ahead.
As illustrated in Figures 5 and 6, ink sac 2 comprises the flexible pocket main body 21 of the aluminium lamination film of general square shape (being rectangle in this example), and the supporting member 22 fixing (welding) of a resin material is to the long limit of this capsule main body.
As shown in Figure 7, capsule main body 21 is formed by aluminium lamination film 30, and its structure is for wherein dried interlayer (drylamination) 26, aluminium film 27, dried interlayer 28 and PA (polyamide) film 29 are layered in a LDPE (low density polyethylene (LDPE)) substrate 25 continuously.Therefore, two such aluminium lamination films 30 and 30 circle segment (shadow region of Fig. 2) be fused to together and and then be fused on the supporting member 22, thereby form as illustrated in Figures 5 and 6 capsule.
It should be noted that capsule main body 21 is not provided for supporting the framework of scrotiform shape, different with the capsule of routine, thereby the entire portion of this capsule has very high flexibility.So the present invention can make the untapped useless China ink that remains in the capsule minimum.
Here, although it should be noted that capsule main body 21 is formed by aluminium lamination film 30 in the present embodiment, the material that is used for capsule main body 21 is not limited thereto.Preferably, use the material that comprises the aluminium lamination film at least to form the capsule main body.
In addition, preferred, wide (W) high (H) that sets capsule main body 21 than (W/H) in 1≤W/H≤1.5 or depth-width ratio (H/W) in the scope of 1≤H/W≤1.5, to guarantee enough hydrostatic pressures and to reduce black residual quantity.
Here, refer to figs. 14 and 15 the relation between the hydrostatic pressure of shape that capsule main body 21 is described and discharging opening for permitting discharging of the toner.
In this example, the shape of capsule main body 21 is defined as rectangle (wide W is greater than high H), as shown in figure 14.Like this, three seed capsules main bodys are tested: 1. high H * wide W is 90 * 116 (1: 1.29), and 2. high H * wide W is 70 * 106 (1: 1.5), and 3. high H * wide W is 50 * 126 (1: 2.52).In addition, prepare different two housings (slim and thick type) of thickness for housing 3.
Further, relation between the hydrostatic pressure of black residual quantity and discharging opening for permitting discharging of the toner is measured in the assembling of each seed capsules main body and housing.The result as shown in figure 15.Here, it should be noted that and do not measure being of a size of 50 * 126 the size and the assembling of thick shell.
, should note preferably using about 0 (gf/cm to sub-box (sub tank) ink supply for stably at discharging opening for permitting discharging of the toner
2) hydrostatic pressure.
Now, estimate the result of Figure 15, can see situation 1. wide (W) high (H) of capsule be 1: 1.29 than (W/H), and situation 2. the ratio of width to height of capsule main body (W/H) be under 1: 1.5 the situation, at 0 (gf/cm
2) near can obtain and stable hydrostatic pressure that residual China ink amount is irrelevant, can see that hydrostatic pressure rises to 2 (gf/cm suddenly at the discharging opening for permitting discharging of the toner place when filling about 70g (this amount is less than the aim parameter of 100g) black
2) (slim) or 4 (gf/cm
2).Equally, situation 3. the ratio of width to height (W/H) be in 1: 2.52 the capsule main body, when having filled about 50g black attempting filling the aim parameter of 100g, hydrostatic pressure rises suddenly at the discharging opening for permitting discharging of the toner place.
Thus, can find out, although it depends on the thickness of housing 3, the ratio of width to height of capsule main body 21 (W/H) is in the scope of 1-1.5.
Should note, supporting member 22 is configured for capsule main body 21 is fused to the whole coupling part 32 of a side of flange portion 31, shown in Fig. 8-10, hollow ink filling port 33 and hollow discharging opening for permitting discharging of the toner 34 form integral body (state of representative before welding) at the opposite side of flange portion 31.
Here, it should be noted that two ends (longer sides acies) of coupling part 32 by supporting member 22 attenuate to be roughly chestnut (chestnut) shape, as shown in Figure 9.Further form recess 32a at periphery surface.So, can incessantly the aluminium lamination film 30 and 30 that forms capsule main body 21 be fused to the periphery surface of coupling part 32.
In ink filling port 33, the perforation 35 that is formed for stopping out makes this hole 35 penetrate flange portion 31 and also penetrates coupling part 32, and after China ink being filled in the ink sac 2 frit seal ink filling port 33 (being shown hermetic unit 36 among Fig. 5-6).By thermal welding process sealing ink filling port 33, obtain positiver sealing easily.
With reference to Figure 11, discharging opening for permitting discharging of the toner 34 has cylindrical section 37 and forms whole seal support part 38 with it, and forms interval 39 between cylindrical section 37 and seal support part 38.In addition, form China inks at cylindrical section 37 and portal 40, form in seal support part 38 that opening 41 is used to insert elastic component 45 and the sealing China ink portals 40 to penetrate flange portion 31 and coupling part 32.In addition, form step part 42 between cylindrical section 37 and seal support part 38, cup member to be installed at periphery surface.
As shown in figure 11, the opening 41 that elastic component 45 is inserted into the seal support part 38 of ink outlet port 34 portals 40 to be used to sealing China ink, and elastic component 45 is coated with cup member 46.
The shape of elastic component 45 can support sealing and can be any cylindricality (circular portion), triangle cylindricality, square column type, five corner post shapes, hexagonal cylindricality, heptangle cylindricality, anistree cylindricality or the like.
By cup member 46 being inserted in the supporting part 38 of discharging opening for permitting discharging of the toner 34, fastener 49 engages with step part 42 between cylindrical section 37 that is formed on discharging opening for permitting discharging of the toner 34 and the supporting part 38, and as shown in figure 11, so, cup member 46 can not thrown off.
Here, it should be noted that the cylindrical section 37 of discharging opening for permitting discharging of the toner 34 and supporting part 38 are to be made by the material that can not influence black character (for example high density polyethylene (HDPE)).So, the cylindrical section 37 etc. that prevents to be formed with outlet 40 and often be exposed to China ink is dissolved in the China ink.
Equally, preferably elastic component 45 is made by the material that does not influence black character (for example silicones or silicon-based rubber material).So, having solved the elastic component of formation seal that is exposed to China ink usually is dissolved in the China ink and causes blocking problem.
As shown in figure 11, when hollow ink supply pin 111 thrusts from the tape deck side, as China ink is introduced tape deck draw device for ink the time, this elastic component 45 makes ink supply tape deck and supporting sealing state.
Here, when hollow needle 111 is thrusting the back when taking out, seal 45 still needs to support reliably sealing state, considers to be bearing in the state of thrusting or to be removed reservation in case thrust back hollow needle 111 by hollow needle 111.
Here, 16-17 illustrates hollow needle 111 with reference to the accompanying drawings.
With reference to the accompanying drawings, hollow needle 111 is wherein to be formed with the cylindrical section that draws ink passage 112, and has jet orifice 113 on the distal circumference surface.By forming jet orifice 113 on the side of the distal portions of hollow needle 111, pin can be at its most advanced and sophisticated cusp that forms, and can be easy to pin 111 is penetrated in the elastic component 45 and can not cause defective or space therein.In addition, can not cause that impaired the and injured part of elastic component 45 stops up the problem of ink guiding hole 113.
In addition, it should be noted that cup member 46 can not influence the material of black character by stainless steel etc. and forms.So, even under the situation of the flange portion 47a of contact resilient spare 45 contact China ink, can stop etch or corrosion.
Here will explain result of the test according to the material of elastic component 45.
Use EDPM+Si as the discharging opening for permitting discharging of the toner 34 that is arranged on ink sac 1 in the test of elastomeric material of elastic component 45, can be observed and under 50 ℃ of humidity 35%, temperature, penetrating elastic component after 45 about 1 weeks when supporting hollow needle 111, remove under the situation of hollow needle 111, ink leakage takes place in the pin hole place.
Thus, inventor of the present invention tests when this hollow needle 111 being taken out after penetrating 3 days with empty needle 111 in the middle of whether confirming under 50 ℃ of humidity 35%, temperature various materials, the rubber slab that is penetrated by hollow needle 111 has optical channel, various materials comprise: and EPDM+Si (40 ° of hardness, thickness t=2mm); EPDM+Si (50 ° of hardness, thickness t=2mm); Fluorubber (55 ° of hardness, thickness t=2mm); Butyl rubber (50 ° of hardness, thickness t=2mm); Silicone rubber (market product of hardness the unknown, thickness t=2mm); Silicone rubber (40 ° of hardness, thickness t=2mm); Silicone rubber (50 ° of hardness, thickness t=2mm).
