CAPILLARY THERMAL INK JET PEN
Teç~nical Field This invention relates generally to thermal ink jet pen construction and more particularly to a single or multi-compartment pen body having improved ink storage and distribution capabilities.
~ackq~9~_a~
In the art of the~mal ink jet printing, it is Xnown to provide a bladder type of ink reservoir for sup-plying ink to a ther~al ink jet printhead. The printheàd will typically include a thin film resistor (TFR) substrate having a plurality of heater re~i tors th~rein, and a bar-rier layer and orific~ plat~ member is usually moun~ed on top of the thin film re~istor sub~tra~e.

Whereas these bladder type reservoirs have proven generally satisfactory for certain types of thermal ink jet (TIJ) printers, they nevertheless take up too much space and are unable to hold a sufficiently large volume of ink for other types of printer applications.
Disclosure of Invention Accordingly, the general purpose of this invention is to provide new and improved pen body construction adapted for use in thermal ink jet printers. This new pen body construction represents a significant departure from the bladder-type ink storage approach and includes a novel printhead and ink storage structural arrangement. In this arrangement, the above problems associated with the ink storage and ink delivery mechanisms of the prior art have been either eliminated or substantially minimized.
To accomplish this purpose, we have discovered and developed a novel p~n body construction which includes a certain ink storage foam which is preferably a controlled porosity polyurethane foam. This foam has been reticulated to break the walls of small membranes within the foam material and thereby increase the mobility o~ ink flow therein. ~he foam is also compressed to reduce the pore size therein to in turn reduce the foam thickness while increasing its 1~3~%
density. In this manner, the desired capill~rity of the foam can be controlled. sy this process, th~ capillary force of the foam i5 increased and thereby renders this ink storaga mediu~ ~spQcially well suited ~or feeding ink to a thin film resistor typ~ o~ thermal ink jet printhead. Fur-ther~ore~ thi~ ink feed apparatu~ i~ provided using a mini-mum of space (volumQ) to houss th~ ~oa~, and it features a corresponding maximum of ink storage capability in the foam.
In addition, this polyur~than~ ~oa~ 1~ economical to provide and is particularly adaptablG for insertion into separate adjacent compartments o~ a pen body housing.

The various advantages and novel features of this pen body construction will become more readily apparent in the following description of the accompanying drawing.
Brief Description Qf the Drawin~s Figure 1 is an exploded view of the pen body construction according to one embodiment o~ the invention; and Figure 2 is a cross section view taken along lines 2-2 of Figure 1.
4f . '. ' ' "' ~
a3~J3~S~2 Best Mode for Carrying Out the Invention Referring now to Figure 1, there is shown a three compartment pen ~ody designated generally as 10 and having three (3) ink storage compartments 1~, 14 and 16 therein as indicated by the dashed line divider partitions within the interior of the body 10. The pen body 10 further includes an output printhead support surface 18 which is joined to upstanding side walls 20 in a rectangular recsptacle config-uration. This structure furth0r includes three (3) ink output port 22, 24 and 26 respectively communicating with the three ink stora~e compartments 12, 14 and 16.
The rectangular support receptacle 18 is con~i-gured to receive a thin film resistor type printhead 28 having a plurali~y of ink ejection orifice groups 30, 32 and 34 respectively which are ~ircular in geometry and which communicate with the ink flow passages 22,2~ and 26 extending to th~ surface 18 o~ the rectangular support receptacle.
_ In the assembly of Figure 1, three ink filters 36, 38 and 40 are mounted within the compartments 12, 14 and 16, respectively. These filters are t~pically constructed from stainless wire mesh o~ a desired porosity to provide good filtration of air bubbles and solid particles when passing ink ~rom the three sections 42, 44 and 46 of poly-urethane foam located in the three compartments 1~, 14 and 16 of the pen body 10.
. .
. . ' .. . ' .
- ~3~3~2 The back surface 48 of the foam body section~ 42, 44 and 46 is fitted with a plug generally designated as 50, and this plug including itq end cover 51 prevPnts back-pressure build up and facilitate~ the removal of ink from the foam and through the filters 36, 38 and 40 to the print-head 28. Air vents 52 are covered with porous plastic membranes 54 which prevent ink from leaking out through the air vents 52. The remaining structural detail o~ these three vents 52 and their intermediate wall partitions 6~ and 68 is shown in a larger cross-section view in Figure 2 below. As previously indicated, the ~oam material o~ sections 42, 44 and 46 is a controlled porosity ether-type polyurethane foam which has been reticulated to break the membrane walls therein. This increases the capillary force of the foam and thereby renders it espacially well suited for ~eeding ink along the ink feed paths to a thin ~ilm re~istor thermal ink jet printhea~. The plug 50 fuxther include~ foam compres-sion tab~ 56 which extend into the foam sections 42, 44 and 46 as shown-and provide a deRired amount of compressive forces to the ~oam for further increasing capillary ~orces in the ~oa~ and optimizing ink dispensation to the printhead.
The particular foam which has been used in actual practice is an ether-type foam material obtained from the Scott Paper Company o~ Philadelphia, Pennsylvania and had a - ~
- .. . . : . . : :
- ' '' ' ~ ' ' " ~l3`~?3~2 porosity of between 60 and 75 pores per inch.
Referring now to Figure 2, the cross section view in this figure is taken along lines 2-2 of Figure l wherein like reference numerals have been used in both figures to identify the same components therein. Th~ pen body 10 includes interior walls 62 and 64 which serve to partially define the three compartments for receiYing th~ rectangular sections 42, 44 and 46 of foam as shown in ~igure 1. These interior walls 62 and 64 receive ~he corresponding T-shaped interior extensions 6~ and 68 o~ the cover or end member 51 of the previously described snd plug 50. This plug 50 further includes air ventq 70, 72 and 74 which communicate with the cavities or recessed portions 76, 78 and 80 as shown. These recessed portions or cavitie~ 76, 78 and 80 in the cover member 51 of the plug 50 raceive a plurality of porous membranes 82, 84 and 54 which are fabricated from poly~etraflouroethyleno (PTFE~ and which provide ad qua~e ventilation within ~he three compar~ments o~ ~oa~. At the same time, thes~ membrane~ 8Z, 82 and 54 are o~ su~icient mesh den3ity to prevent ink back flow ~hrough ~he three air vents 70 " 2 and 74.
A plurality of ink chamber~ ~8, 90 and 9~ are provided as shown in the three ink pipe~ 94, 96 and 98, respectively, in the lower regions o~ tha pen body lO. Each of these ink pipes 94, 96 and 98 are provided, respectively, with the three previously identified wire mesh filters 40, ~3~3~Z
38 and 36. These latter filters provide ~iltering of air bubbles and solid particles from the ink which ultimately passes through the ink pipes 88, 90 and 92 and to the TFR
printhead 28. This ink flow path al~o includes the lateral ink passage located between the lower sur~ace 100 of the pen body 10 and the facing s~rface of the semiconductor sub-strate member 10~ of the TFR printhead substrate 28.
The geometrical configuration o~ the ink pipes 94, 96 and 98 in combination with the wall~ S2, 64 and 66 and the spacing therebekween beneath the foam increases the compression o~ the foam in the areas above the three fil-ters. This fact in turn increases the capillarity of th2 foam in the region thereof above these three filters and thus reduces tha possibility of air bubbles interrup~ing the ink path vertically down through the foam and into the three ink pipes 94, 96 and 98.
The substrate member 102 is bond~d to a no~zle plate 104 by means o~ an adhesive barrier 106. Thi barrier 106 may advantageously be a selected polymer material such as the RISTON or VACREL tradQ name polym2r materials made available by the E~ I. Dupont Company of Wilmington, Delaware. Th~ in~ will flow vertically down through the ink pipes 88, 90 and 92 and then into ~he three vertical pas-sages 108, 110 and 112 in the substra~e mem~er 102. These vertical passageways 108, 110 and 112 will ~hen ~eed ink to : 8 . .
-. . ~' ' ' ~3;tJ3~
the plurality of groups of orifices 30, 32 and 34 in the nozzle plate 104 and located in a circular pattern as shown.
The nozzle plate 104 may advantageously be electroformed of nickel and plated with gold and then affixed to the polymer barrier material 106 using, for example, a heat staking process. The nozzle plate 104 may be fabricated in the manner described in the above identified ~ , Vol. 38, No. 5 May 1985.
Finally, the thin film resistor structure 28 is secured to the bottom facing surface 100 of the pen body 10 by means of a suitable adhesive 114 which is disposed as shown at the outer periphery of the substrate 102, as well as at interior recessed wall surfaces 116 and 118 thereof.
The present invention is not limited to thermal ink jet applications and may instead be used in other types of ink jet applications in which the above foam storage-of-ink capability is desirable and compatible.

The rectangular support receptacle 18 is con~i-gured to receive a thin film resistor type printhead 28 having a plurali~y of ink ejection orifice groups 30, 32 and 34 respectively which are ~ircular in geometry and which communicate with the ink flow passages 22,2~ and 26 extending to th~ surface 18 o~ the rectangular support receptacle.
_ In the assembly of Figure 1, three ink filters 36, 38 and 40 are mounted within the compartments 12, 14 and 16, respectively. These filters are t~pically constructed from stainless wire mesh o~ a desired porosity to provide good filtration of air bubbles and solid particles when passing ink ~rom the three sections 42, 44 and 46 of poly-urethane foam located in the three compartments 1~, 14 and 16 of the pen body 10.

- ~3~3~2 The back surface 48 of the foam body section~ 42, 44 and 46 is fitted with a plug generally designated as 50, and this plug including itq end cover 51 prevPnts back-pressure build up and facilitate~ the removal of ink from the foam and through the filters 36, 38 and 40 to the print-head 28. Air vents 52 are covered with porous plastic membranes 54 which prevent ink from leaking out through the air vents 52. The remaining structural detail o~ these three vents 52 and their intermediate wall partitions 6~ and 68 is shown in a larger cross-section view in Figure 2 below. As previously indicated, the ~oam material o~ sections 42, 44 and 46 is a controlled porosity ether-type polyurethane foam which has been reticulated to break the membrane walls therein. This increases the capillary force of the foam and thereby renders it espacially well suited for ~eeding ink along the ink feed paths to a thin ~ilm re~istor thermal ink jet printhea~. The plug 50 fuxther include~ foam compres-sion tab~ 56 which extend into the foam sections 42, 44 and 46 as shown-and provide a deRired amount of compressive forces to the ~oam for further increasing capillary ~orces in the ~oa~ and optimizing ink dispensation to the printhead.
The particular foam which has been used in actual practice is an ether-type foam material obtained from the Scott Paper Company o~ Philadelphia, Pennsylvania and had a - ~
- .. . . : . . : :
- ' '' ' ~ ' ' " ~l3`~?3~2 porosity of between 60 and 75 pores per inch.
Referring now to Figure 2, the cross section view in this figure is taken along lines 2-2 of Figure l wherein like reference numerals have been used in both figures to identify the same components therein. Th~ pen body 10 includes interior walls 62 and 64 which serve to partially define the three compartments for receiYing th~ rectangular sections 42, 44 and 46 of foam as shown in ~igure 1. These interior walls 62 and 64 receive ~he corresponding T-shaped interior extensions 6~ and 68 o~ the cover or end member 51 of the previously described snd plug 50. This plug 50 further includes air ventq 70, 72 and 74 which communicate with the cavities or recessed portions 76, 78 and 80 as shown. These recessed portions or cavitie~ 76, 78 and 80 in the cover member 51 of the plug 50 raceive a plurality of porous membranes 82, 84 and 54 which are fabricated from poly~etraflouroethyleno (PTFE~ and which provide ad qua~e ventilation within ~he three compar~ments o~ ~oa~. At the same time, thes~ membrane~ 8Z, 82 and 54 are o~ su~icient mesh den3ity to prevent ink back flow ~hrough ~he three air vents 70 " 2 and 74.
A plurality of ink chamber~ ~8, 90 and 9~ are provided as shown in the three ink pipe~ 94, 96 and 98, respectively, in the lower regions o~ tha pen body lO. Each of these ink pipes 94, 96 and 98 are provided, respectively, with the three previously identified wire mesh filters 40, ~3~3~Z
38 and 36. These latter filters provide ~iltering of air bubbles and solid particles from the ink which ultimately passes through the ink pipes 88, 90 and 92 and to the TFR
printhead 28. This ink flow path al~o includes the lateral ink passage located between the lower sur~ace 100 of the pen body 10 and the facing s~rface of the semiconductor sub-strate member 10~ of the TFR printhead substrate 28.
The geometrical configuration o~ the ink pipes 94, 96 and 98 in combination with the wall~ S2, 64 and 66 and the spacing therebekween beneath the foam increases the compression o~ the foam in the areas above the three fil-ters. This fact in turn increases the capillarity of th2 foam in the region thereof above these three filters and thus reduces tha possibility of air bubbles interrup~ing the ink path vertically down through the foam and into the three ink pipes 94, 96 and 98.
The substrate member 102 is bond~d to a no~zle plate 104 by means o~ an adhesive barrier 106. Thi barrier 106 may advantageously be a selected polymer material such as the RISTON or VACREL tradQ name polym2r materials made available by the E~ I. Dupont Company of Wilmington, Delaware. Th~ in~ will flow vertically down through the ink pipes 88, 90 and 92 and then into ~he three vertical pas-sages 108, 110 and 112 in the substra~e mem~er 102. These vertical passageways 108, 110 and 112 will ~hen ~eed ink to : 8 . .
-. . ~' ' ' ~3;tJ3~
the plurality of groups of orifices 30, 32 and 34 in the nozzle plate 104 and located in a circular pattern as shown.
The nozzle plate 104 may advantageously be electroformed of nickel and plated with gold and then affixed to the polymer barrier material 106 using, for example, a heat staking process. The nozzle plate 104 may be fabricated in the manner described in the above identified ~ , Vol. 38, No. 5 May 1985.
Finally, the thin film resistor structure 28 is secured to the bottom facing surface 100 of the pen body 10 by means of a suitable adhesive 114 which is disposed as shown at the outer periphery of the substrate 102, as well as at interior recessed wall surfaces 116 and 118 thereof.
The present invention is not limited to thermal ink jet applications and may instead be used in other types of ink jet applications in which the above foam storage-of-ink capability is desirable and compatible.
