The specific embodiment
At first, with reference to figure 1 and Fig. 2, wherein shown ink pack assembly 1, it is by ink bag 2 and pack 4 and constitute, and sealing packing 4 is sealing or the form that covers the fluid-tight closing bag of this ink bag 2.Ink bag 2 is arranged to not saturating fluid ground and is contained ink, and this ink has passed through the above-mentioned degassing or pump-down process.Discussed in more detail below, pack 4 and be filled with inert gas, the solubility of this gas in ink is lower than air.In this embodiment, pack 4 and be filled with helium.If desired, sealing packing 4 is evacuated to subatmospheric and through the decompression state after suitably determining, has just contacted with the outer surface of ink bag 2 thereby pack 4.
Each that is used to form in these two sheets of ink bag 5 is the layer structure of following formation: the intermediate layer of aluminium alloy; The first binder layer that forms in this aluminium alloy interlayers apparent surface one of them; The nylon skin that on this first binder layer, forms; The second binder layer that on another surface in intermediate layer, forms; PETG (PET) layer that on this second binder layer, forms; The 3rd binder layer that on pet layer, forms; And the inner layer of polypropylene that on the 3rd binder layer, forms.The ink bag 5 that is formed by above-mentioned laminate has the durability of height.Especially, inner layer of polypropylene makes the ink that contains in 5 pairs of these ink bags 5 of ink bag have the corrosion resistance of height, and aluminium alloy interlayers prevents that the gas infiltration from passing this ink bag 5 simultaneously, prevents that thus the change of ink degassing or exhaust is bad.
The jet pipe 7 of welding on the opening 5a of ink bag 5 is forms of a casing component or hollow circuit cylinder body member, and it is to have the corrosive polyacrylic material of highly anti-ink to form by main component.Promptly, the main component of the material of jet pipe 7 is identical with the material of ink bag 5 internal layers, thereby a plurality of rib 7a that form on jet pipe 7 outer surfaces can be securely fixed on the opening 5a, therefore can prevent that the weld that gas communication is crossed between ink bag 5 and the jet pipe 7 from entering this ink bag 5, prevent that thus the change of ink degassing in the ink bag 5 or exhaust is bad.The passage 6 that passes jet pipe 7 and form has the intermediate space 20 that forms between opposed end 18,19.The interior diameter in this space 20 is greater than the interior diameter of described opposed end 18,19, and is arranged for and holds stopper 8.
Stopper 8 is by butyl rubber or have high flexibility or elastic similar material forms, with guarantee go out when the ink that punctures stopper 8 lancet 17 (will be described in detail later) from stopper 8, remove after this ink bag 5 have enough fluid sealabilities.As mentioned above, stopper 8 press fit in the space 20 of passage 6 of jet pipe 7.When stopper 8 was gone out lancet 17 and punctures by ink, the inner end portion 18 of passage 6 prevented that stopper 8 from moving towards the inner opening end (towards the inner space of bag 5) of jet pipe 7.When removing ink go out lancet 17 from stopper 8, the outer end portion 19 of passage 6 prevents that stopper 8 from moving towards the outer openend of jet pipe 7.
As shown in Figure 3, the ink bag housing 12 that holds the ink bag 5 of formation like this comprises upper element 12a and lower element 12b, and they have essentially identical structure.Among upper element 12a and the lower element 12b each has rectangular bottom wall 9, and four sidewalls 10 that extend respectively from four lateral edges of this diapire 9.Upper element 12a and lower element 12b are docking together on the end face of four sidewalls 10, thereby limit an inner space 11 that wherein holds ink bag 5, make that the corresponding main surfaces of the shape that being roughly of ink bag 5 the is flat diapire 9 relative with this is relative.
The diapire 9 of each has the rectangle inner surface among the upper element 12a of ink bag housing 12 and the lower element 12b, and their size is identical with the corresponding main surfaces of ink bag 5 substantially.One among upper element 12a and the lower element 12b in four sidewalls 10 of each has otch 10a, thereby two element 12a, common cooperation of the otch 10a of 12b and limit an almost circular hole, in this hole, be equipped with the outer end portion of jet pipe 7 securely, thereby be assemblied in opening that the stoppers 8 in the passage 6 can form by the corresponding sidewall 10 of upper element 12a and lower element 12b and approaching.The ink bag housing 12 that holds ink bag 5, just the saturating fluid ground of ink bag 2 seals or is contained in and packs in 4.
Pack 4 and formed by two sheets that are respectively the layer structure form, they do not allow air penetration to pass wherein, and are similar with two sheets that above-mentioned ink bag 5 is used.These two sheets are stacked on top of each other, and along they peripheral thermal welding together, thereby form the sealing bag form pack 4.Sealing packing 4 prevents that air penetration from passing and wherein enters in its inner space, prevents that therefore air penetration from arriving in the ink bag 5, otherwise this air can be dissolved in the ink, and reduces the ink degassing degree in the ink bag 5.
Pack 4 inner spaces that hold ink bag 2 and be filled with or fill helium.Gap between the butt joint end face of the upper element by ink bag housing 12 and the sidewall 10 of lower element fills helium also for the inner space of ink bag housing 12.Pass ink bag 2 although helium can permeate, the amount of helium of dissolving in the ink that is not contained in the ink bag 5 is dissolved in the air capacity in this ink saturating fluid less than meeting, and this is because the solubility of helium in ink is lower than the air.Therefore, the bad degree of change of the ink degassing that is caused by helium is starkly lower than the bad degree of change of the ink degassing that air causes.Packing 4 inner space can remain under a decompression or the negative pressure, remain on atmospheric pressure or high pressure or direct draught.Be evacuated to when decompression when packing 4, determine this decompression and make under the atmospheric pressure effect that packs 4 outsides, pack 4 and just contacted with the intimate of ink bag housing 12.For example, for atmospheric pressure, select this decompression between-the 60kPa, preferably select this decompression between-the 60kPa at-40kPa at-20kPa.Remain on when the inner space that packs 4 under the situation of malleation of rising, utilize to be contained in the helium in the sealing packing 4 and to make sealing packing 4 remain swelling state.When the inner space that packs 4 remains under a high pressure or the approaching atmospheric pressure, in ink pack assembly 1 transportation, fall or when this ink pack assembly 1 applies external force when ink pack assembly 1, the impact that can act on the sealing packing 4 is absorbed by being contained in the helium that packs in 4, thereby prevents that this ink bag housing 12 from damaging.
Packing the gas of filling 4 inner spaces and be not limited to helium, can be suitable rare gas, neon for example, and perhaps solubility is lower than other inert gas of air in ink.
Below with reference to Fig. 6, the method for making the ink pack assembly 1 that as above constitutes is described.At first, when ink bag 5 is configured to make passage 6 when vertical direction extends, the ink bag 5 that is contained in the ink bag housing 12 is come filling ink by the passage 6 that passes jet pipe 7 and form.In this embodiment, ink bag 5 does not have complete filling that ink is arranged, just ink bag 5 is filled to and makes the passage 6 of jet pipe 7 not have filling ink, to avoid because ink attached on the inner surface of passage 6 and cause the inner surface of passage 6 and press fit over poor sealing between the outer surface of the stopper 8 in this passage 6.In this mode of filling this ink bag 5 with ink, the part place of the lower open end of close jet pipe 7 in ink bag 5 inner spaces, this ink bag 5 has a cavity 22 that does not have filling ink, as shown in Figure 6.
When the inner space that packs 4 is evacuated, in the space 20 of the passage 6 that stopper 8 is press fit over jet pipe 7 before, the ink bag 2 that will hold the ink bag 5 that is filled with ink as mentioned above is contained in and packs in 4.Be enclosed in the ink bags 2 that pack in 4 then and be placed in the vacuum chamber 21, be in and pack 4 opening-wide state, thereby cavity 22 in the passage 6, ink bag 5 and the inner spaces that pack in 4 keep being exposed under the reduced pressure.
Vacuum chamber 21 is filled with helium, cavity 22 and pack 4 inner space and remain and be exposed under the reduced pressure simultaneously, thereby passage 6, cavity 22 and pack 4 inner space and be filled with helium.The helium volume that is incorporated into passage 6, cavity 22 and packs in 4 has determined to pack 4 interior pressure.Then, stopper 8 is press fit in the passage 6 of jet pipe 7, will pack 4 opening saturating fluid ground sealing with thermal welding operation, while ink bag 2 remains in the vacuum chamber 21.Therefore made this ink pack assembly 1.
Packing 4 therein is filled with in the ink pack assembly 1 of manufacturing like this of helium, ink bag 5 and jet pipe 7 are passed in infiltration and the amount of helium that can be dissolved in the ink in the ink bag 5 is significantly less than the amount that can be dissolved in the air in the ink, because the solubility of helium in ink is lower than air.Therefore, helium can significantly not make the degassing of ink or exhaust significantly become bad.Although there is not the cavity 20 of filling ink still to be retained in the ink bag 5, filled helium rather than air in this cavity 20, therefore make the bad degree minimum of change of the degassing of ink.
In the manufacture method of this ink pack assembly 1, when the inner space that packs 4 was filled with helium, the passage 6 of ink bag 5 and cavity 22 also all were filled with helium.But, by at first stopper 8 being press fit in the passage 6 of jet pipe 7, fill helium for then vacuum chamber 21, passage 6 and cavity 22 can be evacuated to decompression state.In this case, only pack 4 inside and be filled with helium.In the ink pack assembly of making like this 1 and since helium in ink than low solubility, even pass under the situation of ink bag 5 or jet pipe 7 in the helium infiltration, the bad degree of the change of the ink degassing that is caused by helium is also less.Because the passage 6 and the cavity 22 that are retained in the ink bag 5 are evacuated to subatmospheric decompression state, therefore reduced the meltage of air in the ink that is not contained in the ink bag 5 saturating fluid, further reduced the bad degree of change of ink degassing thus.
When the ink pack assembly 1 that as above constitutes is used for ink jet recording device, open and pack 4, ink bag 2 is taken out in sealing packing 4, as shown in Figure 7.Ink bag 2 is installed on the ink jet recording device, and ink bag housing 12 is moved along the guiding piece (not shown) that is provided with on this equipment.Go out lancet 17 with ink then and puncture stopper 8, thereby the free end of pin 17 is positioned at ink bag 5.Ink goes out lancet 17 and is connected to the record head of recording equipment by the feed line 16 of tubulose, thereby provides ink to record head.
Below with reference to Fig. 8 and 9, description comprises ink bag 26 and the ink pack assembly 28 that constitutes according to the utility model second embodiment.This ink bag 26 is included in the reinforcement structure 23 that is provided with between the outer surface of ink bag 5 and ink bag housing 12 inner surfaces.This reinforcement structure 23 is set prevents the distortion of ink bag housing 12 or subside, and this distortion or subside and can cause bad influence to the ink bag of adorning in the ink bag housing 12 5.Sealing of promptly saturating fluid ground or the decompression that packs in 4 inner spaces of holding ink bag 26 can act on the ink bag housing 12, thereby the active force that produces because of this decompression can make ink bag housing 12 be out of shape or subside.
Strengthening structure 23 is made of the first grid element 23a and the second grid element 23b, wherein this first grid element 23a has the curved surface of one of them first type surface of contact or covering ink bag 5, and the second grid element 23b has contact or covers the curved surface of another first type surface of ink bag 5.In this embodiment, the first and second grid element 23a, 23b are lower element and upper elements as shown in Figure 8.Because the first and second grid element 23a, the structure of 23b is consistent each other, therefore only describes the first grid element 23a.Below describe and be equally applicable to the second grid element 23b.
The first grid element 23a comprises and is roughly forniciform substrate 24 and grid 25, when this first grid element 23a was positioned on the appropriate location of ink bag housing 12, substrate 24 and grid 25 laid respectively on the side of a first type surface of above-mentioned ink bag 5 and on inner surface one side of the diapire 9 of ink bag housing 12.Grid 25 is fixed on being among the apparent surface on diapire 9 one sides one of substrate 24.
Substrate 24 comprises bigger crooked middle body 24c, and the curvature of this part is being followed the curvature of an above-mentioned first type surface of ink bag 5, and wherein when ink bag 5 was equipped with ink, this first type surface was protruding.Substrate 24 also comprise two narrower, parallel and be flat peripheral part 24a, 24a, they are positioned on each opposite side of crooked middle body 24c, substrate 24 also comprises neck 24b, and this part is extended towards the end of ink bag 5 on jet pipe 7 one sides from the corresponding end of crooked middle body 24c.Described parallel flat peripheral part 24a is positioned at the outside of crooked middle body 24c.As shown in Figure 9, the shape of crooked middle body 24c so constitutes, thereby as the first and second grid element 23a, when 23b is arranged in the ink bag housing 12, make the first and second grid element 23a, common cooperation of the crooked middle body 24c of 23b and limit the space of an ink bag 5 that holds to be filled with ink, this ink bag 5 is clamped.Along seeing that with the vertical and parallel plane of diapire 9 (corresponding main surfaces of ink bag 5) this space is the cross section substantially and reduces shape gradually with flat peripheral part 24a.This is the space that reduces shape gradually substantially along extending away from one opposed end of the otch 10a direction towards another end that is provided with this otch 10a from housing 12.That is, the distance between two crooked middle body 24c reduces away from the direction of the opposed end of this neck 24b towards this middle body 24c gradually along the end that is provided with neck 24b from above-mentioned each middle body 24c.When the first grid element 23a was arranged in the ink bag housing 12, from the direction perpendicular to diapire 9, the size of substrate 24 roughly equated with the size of ink bag 5 or is more bigger than it.
Grid 25 is made of a plurality of first strip parallel walls parallel with narrower flat peripheral part 24a and a plurality of second strip parallel walls vertical with this first parallel walls.These first and second parallel walls from substrate 24 away from an extension the corresponding main surfaces of ink bag 5, thereby this first and second parallel walls is perpendicular to an above-mentioned first type surface of substrate 24.First and second parallel walls of grid 25 have and the contacted end face of the inner surface of diapire 9.Just, these end faces define a plane parallel with the inner surface of diapire 9 substantially.Substrate 24 and grid 25 can be used as reinforcing element 23 by whole formation of resin material, but grid 25 can be formed by paper material (corrugated fiber board).
The first and second grid element 23a, 23b are positioned on each opposite side of ink bag 5, thereby clip ink bag 5.Because grid element 23a, the substrate 24 of 23b has essentially identical size with the first type surface that is filled with the ink bag 5 of ink, so grid element 23a, and two flat peripheral part 24a of 23b are common to be cooperated to clip the corresponding peripheral part relatively of ink bag 5.In this case, the jet pipe 7 of ink bag 5 is by two grid element 23a, and the neck 24b of 23b is clipped in wherein.Reinforcing element 23 is positioned at the appropriate position of ink bag housing 12, thus the first and second grid element 23a, and the grid 25 of 23b is positioned on the side of diapire 9 of housing 12.
Identical with ink bag 2 used in first embodiment, the ink bag 26 that comprises the reinforcing element 23 of formation like this is sealed or is contained in by saturating fluid ground and packs in 4.Pack 4 inner space and be evacuated to subatmospheric decompression.For atmospheric pressure, this decompression is selected from approximately-20kPa is to the scope of-60kPa, preferably approximately-40kPa.In addition, pack and be filled with helium in 4.The inner space that packs 4 found time and be to its result who fills helium, by upper element and lower element 12a, the gap between the 12b, the inner space of ink bag housing 12 also is evacuated and is filled with helium.When decompression is selected from above-mentioned scope, pack 4 and just contact with the outer surface of housing 12, can avoid because this decompression causes housing 12 deflections excessive.
At the upper element and the lower element 12a of ink bag housing 12, when the diapire 9 of each had large surface area among the 12b, owing to pack 4 interior decompressions, this diapire 9 partly may have the danger of some distortion in the central.But in housing 12, have under the situation of reinforcing element 23, the active force that produces based on packing the decompression in 4 is received by reinforcing element 23, even therefore when diapire 9 has large surface area, also can prevent upper element and lower element 12a substantially, the distortion of the diapire 9 of 12b by this reinforcing element 23.
Because ink bag 5 is by the first and second grid element 23a of reinforcing element 23,23b clips, and therefore the active force that produces based on the decompression that packs in 4 is received by reinforcing element 23, can not act on the ink bag 5.Therefore reinforcing element 23 protection ink bags 5 can not break and make subsequently ink to leak out from ink bag 5 because of decompression.
When the inside that packs 4 be evacuated to approximately-during the decompression of 40kPa, the initial degree that is difficult to the degassing or the exhaust of long term maintenance ink.Therefore in this second embodiment, with the residual air helium replacement that packs in 4, and by upper element and lower element 12a, the gap between the 12b also is filled with helium for the inner space of ink bag housing 12.Even ink bag 5 is passed in the helium infiltration, because helium has lower solubility in ink, therefore the amount of helium that can be dissolved in the ink is also lacked than the air capacity that meeting is dissolved in the ink.Therefore, can reduce the bad degree of change of ink degassing.
Pack 4 inner space and can be filled with helium, and remain on and be not less than under the atmospheric pressure, to reduce the bad degree of change of ink degassing.But in this case, pack 4 and be expanded to larger volume, greatly increased the volume of making as a whole ink pack assembly 28, thereby in the transportation of ink pack assembly 28 and storing process, have problems.When helium remains on when being not less than under the atmospheric pressure, in the operating period of ink pack assembly 28, form owing to pass the part that packs 4 pin-and-hole etc., exist helium from packing 4 high risk of leaking.Under atmospheric pressure or elevated pressures, be not easy to detect the leakage of this helium usually, and this leakage can cause ambient air to flow into packing in 4, and make ink degassing take place to become bad subsequently.
But in this embodiment, pack 4 and be filled with the helium that remains below under the atmospheric pressure (for example approximately-40kPa), thereby pack 4 and remain compact state and not expansion, and can cause this packing 4 to be separated mutually because air flow into to pack by pin-and-hole in 4, so can more easily detect and in the operating process of ink pack assembly 28, pass the part formation that packs 4 pin-and-hole etc. with the outer surface of ink bag 26.Therefore, before being used in ink pack assembly 28 on the ink jet recording device, can more easily detect the ink pack assembly 28 of damage.
The gas of filling 4 inner spaces that packs of this ink pack assembly 28 is not limited to helium, can be the suitable rare gas of neon for example, or its solubility in ink is lower than other inert gas of air.
Similar with the ink pack assembly 1 of first embodiment, cavity 22 by the ink bag 5 that will (be filled with ink) in the vacuum chamber 21 that is filled with helium and pack 4 inner space and be evacuated to required decompression state (approximately-40kPa), thus cavity 22 and the inner space that packs 4 are filled with helium, can make the ink pack assembly 28 of second embodiment.Then stopper 8 is press fit in the passage 6 of jet pipe 7 of ink bag 5, and will pack opening saturating fluid ground sealing of 4, be contained in sealing packing 4 interior ink bags 26 simultaneously and remain in the vacuum chamber 21 by thermal welding.
In the ink pack assembly 28 that as above constitutes and make, stay cavity 22 in the ink bag 5 and that do not have filling ink and be filled with helium, and the amount of helium that is dissolved in the ink is less than the air capacity that can be dissolved in the ink, thereby can reduce the bad degree of change of the degassing or the exhaust of the ink of adorning in the ink bag 5.
And space that wherein holding ink bag 5 that limited by the reinforcing element 23 that is positioned at ink bag 5 is the cross section substantially and reduces shape gradually, as shown in Figure 9, thereby along direction towards the sidewall with otch 10a 10 of housing 12, the first and second grid element 23a, the distance between the 23b increases gradually.Therefore, the ink volume of holding in the close relatively part of jet pipe 7 of ink bag 5 is much larger than the quantity of ink that holds in ink bag 5 relative other parts away from jet pipe 7.This structure makes ink to go out lancet 17 and feed line 16 by ink from ink bag 5 and transmits glibly to ink jet recording device.
Will pack decompression in 4 be adjusted into make sealing packing 4 just with the contacted above-mentioned ink pack assembly 28 of the outer surface of ink bag 26 in, prevented the distortion of ink bag 26 during the transportation of this assembly 28 or this assembly 28 long preservation, and this distortion suitably is installed on the ink jet recording device this ink pack assembly 28 obstruction.In addition, the reinforcing elements 23 in the ink bag housing 12 have received the active forces that decompression produced that pack in 4, even and when ink bag 26 has big first type surface, can prevent that also the housing 12 of this ink bag 26 is out of shape because reduce pressure.In addition, the filling of employing helium packs 4 inner space, has reduced the bad degree of change of ink degassing effectively, because the solubility of helium in ink is lower than the solubility of air.Therefore this ink pack assembly 28 has been guaranteed the good record quality of recording equipment, and the record problem that bubble brought that in ink bag 5, does not produce.
The same with ink pack assembly 1 in the first embodiment, pack that 4 inner space can remain on a high pressure or direct draught or near under the atmospheric pressure.In this case, be applied to the helium that the impact on the ink bag housing 12 can be maintained under this pressure and absorb, therefore can protect housing 12 can not damage because of impact.
Although described the above-mentioned preferred embodiment of the utility model in order to illustrate, but be appreciated that, the utility model is not limited to the details of above-mentioned embodiment, but can carry out various changes, change and the improvement that those skilled in the art can carry out, still can not break away from spirit and scope of the present utility model simultaneously.
Although ink bag 2,26 all comprises ink bag 5 and ink bag housing 12, described ink can directly be contained in or be contained in the housing 12, and does not use ink bag 5.Perhaps the ink bag can not comprise ink bag housing 12.In this case, ink bag 5 can directly be enclosed in and pack in 4.
In addition, ink pack assembly 28 can improve, and makes that direct housing containing ink 12 is strengthened by suitable reinforcing element, perhaps makes ink bag 5 be strengthened by the suitable reinforcing element that packs in 4, and does not have ink bag housing 12.
