Description
The application is that the application number submitted on March 18th, 2003 is 03120738.3, denomination of invention is divided an application for the application of " liquid container sealing sheath and the method for opening the liquid container that this sheath is housed ".
Technical field
The present invention relates to a kind of liquid container, this liquid container is used for storing the recording liquid of the ink gun that supplies to ink jet recording device, ink for example, and removably be connected to liquid supply path to ink gun.More particularly, relate to a kind of liquid container that is configured to can not allow the problem generation such as ink spattering.
Background technology
Routinely, ink is ejected on the recording medium to form the ink jet print head of image on recording medium, adopts a kind of print cartridge that supplies to record head from its ink through ink supply conduit etc.Various types of changeable ink boxes of ink jet print head have been proposed to be independent of.These changeable ink boxes multiple comprises that a shell and one are included in the shell so that keep the ink absorption part of ink.They are connected on the ink supply conduit that points to ink jet print head.For the ease of providing ink is arrived ink jet print head, and also in order to prevent that ink from spilling from the print cartridge blow vent, the print cartridge inner space is connected in the surrounding air through the print cartridge blow vent, more known containers are configured to, ink absorption part ink content is big near the remainder of ratio at the print cartridge outlet of print cartridge ink, and ratio is medium and small at the print cartridge remainder near blow vent.
The possibility that has ink to leak through its ink outlet and/or blow vent from the print cartridge of above-mentioned exchangeable.Thereby common way is to place a sealing sheath that can seal ink outlet and blow vent around print cartridge, so that prevent ink leakage.According to prior art, place a sealing sheath around print cartridge, thereby outlet of the ink of print cartridge and the sealed sheath of blow vent cover.Then, seal airtightly in order to keep print cartridge, part around sealing sheath is exported along ink and the part around the blow vent bond or are thermally welded on the print cartridge.Sealing sheath is cheap, and can keep print cartridge to seal airtightly reliably.Therefore, be widely used for sealing print cartridge.Require the user to open the print cartridge that sealing sheath is housed, more particularly, what opening encapsulation had that the ink outlet of sealing sheath and blow vent do is, by the direct pull sealing sheath from ink export and blow vent near the peel seal sheath.
A kind of like this possibility is arranged, and at print cartridge between the time of shipment, owing to change the increase of the Ink Cartridge inner pressure that causes by environmental factor, unclamp the sealing sheath part that becomes.Thereby, in order to prevent a kind of like this fault, conventional sealing sheath is bondd very securely or is thermally welded on the print cartridge along ink outlet and blow vent part on every side; In other words, make the adhesion strength between sealing sheath and print cartridge quite big around ink outlet and blow vent.Therefore, the user must apply a sizable strength, so that remove sealing sheath.
This produces following problem.That is, for peel seal sheath around ink outlet and blow vent, the user must spur sealing sheath with above-mentioned sizable strength.Yet,, come sizable resistance of the adhesion strength between comfortable sealing sheath and the print cartridge to suddenly disappear in the moment that sealing sheath and the print cartridge part around ink outlet or the blow vent are separated fully.As a result, user's hand unclamps on it is spurring the direction of sealing sheath suddenly, spurs sealing shroud suddenly and leaves print cartridge.Therefore, the ink that is kept sealing by sealing sheath is arranged, particularly from the ink outlet, the possibility of splashing, the user's that makes dirty hand and article on every side.
The ink that splashes has two parts: think between ink absorption part and sealing sheath first's ink and be bonded to originally on one's body second portion ink of sealing sheath.
With reference to Fig. 9 (a), 9 (b) and 9 (c), first's ink stands to act on the direction that the internal volume of print cartridge 51 increases, promptly on the direction of the ink of sucking-off therein in print cartridge, pressure.First's ink also is subjected to the influence of the inertia that the motion of the sealing sheath 52 peeled off suddenly produces.As a result, the ink part 54 between ink absorption part 53 and sealing sheath 52 is pulled out by sealing sheath 52 suddenly.As a result, ink part 54 is broken suddenly.Yet when it broke suddenly, splashing appearred in the ink dot of failing to remain on ink absorption part 53 or the sealing sheath 52.
With reference to Figure 10 (a), 10 (b) and 10 (c), in a single day sealing sheath 52 separates fully with ink outlet 55, and sealing sheath 52 is just wrenched momently by the above-mentioned unexpected motion of user's hand.As a result, the second ink part 54a, or be bonded to the lip-deep ink part of sealing sheath, pass through impact ejaculation sometimes, and splash from the unexpected motion of sealing sheath 52.
Under the situation of some print cartridges, for the purpose that prevents that these inks from partly splashing, lid 62 is welded in the ink outlet 61 at weld seam 64 places and keeps sealing so that guarantee ink outlet 61.Such print cartridge 63 is opened as follows.At first, in order to disconnect the weld seam 64 between lid 62 and ink outlet 61, going up rotatable cover 62 in the opposite direction with the side of the terminal stage rotatable cover of removing at it 62.Then, remove and cover 62.Therefore, really with when the ink outlet separates, can not discharge the internal pressure of print cartridge 63 at lid 62.And, after weld seam 64 disconnects, remove and cover 62, eliminated from the ink outlet and removed 62 the problem of covering suddenly.In other words, the ink spattering that takes place for the print cartridge that adopts the sealing sheath of representing among Figure 10 can not take place for the print cartridge of these types, because the lid of such print cartridge 62 is opened by rotatable cover 62.
Have at print cartridge under the situation of lid of said structure, for uncap must " rotation " it." rotation " means " when holding lid rotation wrist ", carry out this operation for child, old man or with the physiognomy of hand or wrist inconvenience when difficulty.Moreover, weld the lid of this type print cartridge securely, keep and the lid sealing to guarantee print cartridge, increased the difficulty level of rotatable cover.Thereby, wish to have a kind of print cartridge can be by anyone that open, that be used for print cartridge easily sealing sheath always.

The specific embodiment
(embodiment 1)
Fig. 1 is used for describing the overall structure according to first embodiment of print cartridge of the present invention, and Fig. 1 (a) and 1 (b) are respectively the solid and the front view of this print cartridge.
Explanation in passing, in Fig. 1, in order to represent the structure of print cartridge 100, wrap 120 paintings Transparent Parts, and hatching is in adhesive segment 110 and 111.
Fig. 2 is the cutaway view of cartridge body 101 at the plane place parallel with its maximum wall.As being shown by this figure, cartridge body 101 is cuboids, and more flat.Inner space (liquid storage part) comprises two chambers: a chamber 130 wherein keeps a negative pressure force generating member; With ink storage chamber 131, adjacent negative pressure force generating member keeps chamber 130 to arrange.The negative pressure force generating member absorbs and the maintenance ink by producing negative pressure, and ink storage chamber 131 keeps inks.
The partition wall that keeps the negative pressure force generating member chamber 130 and ink storage chamber 131 to separate has one and is connected to each other and is arranged in the negative pressure force generating member adjacent with the diapire of cartridge body 101 through two chamber and keep the passage of the edge of chamber 130.The negative pressure force generating member keeps chamber 130 to have ink outlet 102 and blow vent 104.Ink outlet 102 is fixed on its diapire.Blow vent 104 is in the inner space of cartridge body 101 and the passage on every side, and keeps in the top plate portion of chamber 130 at the negative pressure force generating member.Ink outlet 102 is filled with a pressurized chamber 133, as an ink suction pieces, so that effectively ink is drawn in the ink supply conduit of guiding ink jet print head into.
Secondly, with reference to Fig. 2 (b), will the ink delivery system of print cartridge 100 be described.
When print cartridge 100 being installed in the ink jet recording device (not shown), the ink suction tube 200 of the master component of imaging device enters ink outlet 102, is pressed on the pressure containing part 133.Some of ink suction tube 200 have a filter 201 on the opening that is fixed to expression ink suction tube 200 in the drawings.Then, when the operation ink jet recording device, ink sprays from the ink jet print head (not shown), produces from this power of cartridge body 101 suction inks.As a result, the ink in ink storage chamber 131 is drawn into the negative pressure force generating member keeps in the chamber 130, and then, further be drawn in the ink supply conduit 200, supply to ink jet print head thus through negative pressure force generating member 132.Therefore, the internal pressure in the ink storage chamber 131 descends, and keeps producing pressure differential between the chamber 130 at ink storage chamber 131 and negative pressure force generating member.Because the record of ink jet print head is operated when supplying to ink jet print head continuously, this pressure differential temporarily increases when ink.Yet, because the negative pressure force generating member keeps chamber 130 to have blow vent 104, keep chamber 130 to external opening through blow vent 104 negative pressure force generating members, so surrounding air keeps chamber 130 to enter ink storage chamber 131 through the negative pressure force generating member, in and the pressure differential between ink storage chamber 131 and negative pressure force generating member maintenance chamber 130.During imaging operation, repeat this generation and the neutralization of pressure differential, make ink might supply to ink jet print head reposefully.
Secondly, the seal 105 that is used for sealing blow vent 104 is described.
Fig. 3 is used for the stereogram of sealing sheath 103 of cartridge body 101 shown in the sealed picture 1.Dash area representative in the drawings is fixed to the part of the sealing sheath 103 on the cartridge body 101 by its sealing sheath 103.Sealing sheath 103 is forms of endless belt shown in Fig. 3 or tape.As previously described, sealing sheath 103 comprises cover piece 121 and take-up strap part 120.With reference to Fig. 1, location cover piece 121, thus when cartridge body 101 was wound with sealing sheath 103, cover piece 121 was installed around the ink outlet 102 of cartridge body 101.The material that is used for cover piece 121 is different with the material that is used for take-up strap part 120.Cover piece 121 is one and is pressed in the ink outlet 102 to seal the part of cartridge body 101.Therefore, easily curved elastomer is wished as the material that is used for cover piece 121.
The cover piece 121 of this embodiment is formed by two kinds of materials.That is, be placed to the part that contact with ink outlet 102 with the cover piece 121 of sealing cartridge body 101 and form, and the part that centers on the cover piece 121 of the part that is formed by elastomer forms (Fig. 4) by polypropylene by elastomer.
With reference to Fig. 3, cover piece 121 is fixed on the take-up strap part 120.For the method that cover piece 121 is fixed on the take-up strap part 120, the polypropylene around the cover piece 121 of the elastomer portion of cover piece 121 is partly bondd or be welded on the take-up strap part 120.Although the take-up strap part 120 of present embodiment and cover piece 121 keep together by welding or by means of the use of adhesive, even keep together but the means except that welding or adhesive can be used for a take-up strap part 120 and cover piece 121, also definitely no problem, as long as it guarantees that cover piece 121 is kept securely by take-up strap part 120.
Not only take-up strap part 120 can closely be twined the whole of cartridge body 101 when can keeping cover piece 121 subsides inking water outs 102 to compress, and as shown in fig. 1, and must be able to paste inking water out 102 maintenance cover pieces 121.Consider this fact, the material that hope is used for take-up strap part 120 is a kind of like this film, and its energy thermal contraction one-tenth is consistent with the exterior contour of cartridge body 101.Obviously, take-up strap part 120 can be a film band, and the one end can be welded on the other end in the mode that forms the endless belt after cartridge body 101 twines, thereby cover piece 121 is covered by take-up strap part 120 and keeps.
With reference to Fig. 1 and 3, seal 105 is the integral parts facing to the take-up strap part 120 of the wall of the cartridge body 101 that has blow vent 104.Seal 105 is that with the difference of the remainder of take-up strap part 120 two straight lines of eyelet 115 are parallel to each other.By means of providing of this structural configuration, can easily tear take-up strap part 120 by mentioning seal 105 simply, expose the outlet of blow vent 104 and ink.In other words, can expose blow vent 104 and ink outlet 102 by single action.
By two adhesive segment, promptly have two side surfaces (with the surface of the surface adjacency that has the ink outlet), first and second adhesive segment of take-up strap part 120 one to one of cartridge body 101 on surface of the print cartridge 101 of ink outlet 102, take-up strap part 120 is fixed on the cartridge body 101 with clamping.Because these first and second adhesive segment must peel off with cartridge body 101 when removing take-up strap part 120, their are bondd or be welded on the cartridge body 101.
Secondly, description is used for cover the method for the cartridge body 101 that comprises the ink outlet by means of sealing sheath 103.
The take-up strap part 120 of sealing sheath 103 has cylindrical form, and its girth is greater than the part of the cartridge body 101 that is twined by take-up strap part 120.In order to twine cartridge body 101, cartridge body 101 is placed in the take-up strap part 120 with sealing sheath 103.Then, locate cartridge body 101 and sealing sheath 103 relative to one another, contact thereby cover piece 121 is placed to ink outlet 102.Then, be the use of selectable maintenance anchor clamps (not shown) by means of its structure, cover piece 121 keeps being pressed in the ink outlet 102, as long as anchor clamps do not damage the elastomer portion 121a of cover piece 121.
Secondly, first and second adhesive segment 110 and 111 that scribble adhesive are pressed on the respective side surface of cartridge body 101 with first and second adhesive segment 110 and 111 of boning to it.During this process, must be noted that, thereby do not have air stay adhesive segment 110 and 111 with the corresponding surface of cartridge body 101 between.Secondly, by collapsible film formed take-up strap part 120 thermal contractions, keep cover piece 121 to be pressed in the ink outlet 102 by means of above-mentioned maintenance anchor clamps simultaneously, consistent up to sealing sheath 103 with the exterior contour of cartridge body 101, tightly must be enough to make the generation tension force of sealing sheath 103 to keep by cover piece 121 sealing inks outlets.Therefore, unclamp cartridge body 101, finish to cover the process of cartridge body 101 by means of sealing sheath 103 from keeping anchor clamps.Fig. 1 is illustrated in this process and finishes print cartridge 100 afterwards.
Secondly, with reference to Fig. 4, the relation between ink outlet 102 and cover piece 121 after the thermal contraction of sealing sheath 103 will be described in.Fig. 4 is the cutaway view of ink outlet 102 and the cover piece 121 in ink outlet 102, is used for representing how ink outlet 102 keeps sealing by cover piece 121.In the figure, cartridge body 101 has the cylindrical part 150 that stretches out with the edge around the form of ink outlet from ink outlet 102.The internal diameter of cylindrical part 150 diameter with ink outlet 102 roughly is identical.The end surfaces of cylindrical part 150 has a ledge 151, and the elastomer portion 121a of the cover piece 121 that contacts with its circumferential rib 150 has a groove 125 to the V-arrangement cross section of the ledge 151 that cylindrical part 150 wherein is installed (hereinafter can simply be called V-shaped groove).
With reference to Fig. 4, when being pressed onto ledge 151 in the V-shaped groove 125, ledge enters in the V-shaped groove 125, is pressed on the elastomer portion 121, just as adding sipes 125.Thereby when ledge 151 entered in the V-shaped groove 125, the inclined surface of V-shaped groove 125 was consistent with the profile of ledge 151, was sealed in airtightly between the inclined surface of ledge 151 and V-shaped groove 125.As a result, seal ink outlet 102 airtightly.
Secondly, with reference to Fig. 5 (a)-5 (d) and Fig. 6, one of main purpose of the present invention will be described, promptly a kind of method that is used for opening according to print cartridge of the present invention.Fig. 5 (a) is according to the stereogram of print cartridge 100 of the present invention before opening ink outlet 102; 5 (b) are the stereograms of print cartridge during removing seal 105; Fig. 5 (c) is the stereogram of peeling off print cartridge in the beginning short time afterwards in first adhesive segment 110 of take-up strap part 120; And Fig. 5 (d) is the stereogram of peeling off print cartridge during the advancement stage in first adhesive segment 110 of take-up strap part 120.Fig. 6 is according to the front view of print cartridge 100 of the present invention during opening ink outlet 102.
This embodiment according to a kind of print cartridge of the present invention opens in the following order.At first, remove the seal 105 of covering blow vent 104 to expose blow vent 104.Owing to following reason should at first be carried out this process.The internal pressure of cartridge body 101 is because environmental factor, temperature for example, variation become than environmental pressure height sometimes.Thereby, might work as when opening cartridge body 101, ink spills the unlatching opening of cartridge body 101.Ink content at first opening the negative pressure force generating member 132 in cartridge body 101 wherein is during greater than the ink outlet side of the cartridge body 101 of the ink content in the remainder of negative pressure force generating member 132, rather than the ink content at first opening the negative pressure force generating member 132 (Fig. 2) at cartridge body 101 wherein is during less than the ink outlet side of the cartridge body 101 of the ink content in the remainder of negative pressure force generating member 132, and this possibility is bigger.This is should at first remove because cover the seal 105 of blow vent 104.
At first, the fin 112 (Fig. 5 (a)) of the sealing sheath 103 of user by holding the respective side surface of stretching out cartridge body 101 is removed seal 105.Because the straight hole eye that is used for making seal 105 be easier to remove abuts against between seal 105 and sealing sheath 103 remainders 115, so the user tears sealing sheath 103 easily to remove seal 105.The user can confirm that by finding these eyelets the direction of user's peel seal 105 is correct or wrong.When spurring seal 105 by the user in the drawings by the arrow A indicated direction, seal 105 not only becomes and separates with cartridge body 101, and, remove the parts of sealing sheath 103 between two row eyelets 115.When removing seal 105, expose blow vent 104.And sealing sheath 103 is at the U-shaped cross-section of seeing from direction parallel with its surface to sealing sheath 103 of removing of the part of two row between the eyelets 115.
Explanation in passing, the fin 112 of wishing seal 105 are equipped with and are used for the clear marking that allows User Recognition fin 112 exist.
Secondly, will peeling off of sealing sheath 103 be described.After removing seal 105, sealing sheath 103 remains fixed on the cartridge body 101, and is consistent with the exterior contour of cartridge body 101, and therefore, keeps above-mentioned U-shaped cross-section (Fig. 5 (b)).One of the end of user by catching two lip-deep sealing sheaths 103 that keep being bonded to cartridge body 101 peel seal sheath 103, there is the surface of the cartridge body 101 that has ink outlet 102 in two surfaces of cartridge body 101 toward each other between them.According to the width of sealing sheath 103, be bonded on the cartridge body 101 to other edges from some edges first adhesive segment 110 of sealing sheath 103 (Fig. 1 (b)) with respect to second adhesive segment 110 (Fig. 1 (b)) of cartridge body 101 at the sealing sheath 103 of opposite side.Yet according to the length direction of sealing sheath 103, sealing sheath 103 does not bond with the part of above-mentioned eyelet 115 adjacency.These parts of sealing sheath 103 are configured to hold sealing sheath so that the fin 116 of peel seal sheath 103.This embodiment of print cartridge, promptly print cartridge 100, so construct, thereby it needn't clearly indicate the wherein direction of peel seal sheath 103; Sealing sheath 103 can be peeled off from arbitrary end.For convenience, suppose that clockwise direction is the correct direction of peel seal sheath 103.
First adhesive segment 110 (Fig. 1 (b)) and be bonded on another edge from an edge at second adhesive segment 110 (Fig. 1 (b)) of opposite side width according to sealing sheath 103 with respect to cartridge body 101, make and do not use fin 116 to be difficult to peel seal sheath 103, and therefore force users mainly uses the fin 116 that is defined by the present invention to remove sealing sheath 103.
For peel seal sheath 103, at first, on by the arrow mark B indicated direction shown in Fig. 5 (c), spur adhesive segment 110.The user knows should be gradually rather than peel seal sheath 103 suddenly, because first adhesive segment 110 is pasted on the surface of cartridge body 101 by sizable length according to the length direction of sealing sheath 103.When the user peeled off first adhesive segment 110 gradually, the user can know from experience the power (stress) of the essential appropriate amount of peel seal sheath 103, prevented a large amount of excessively power that applies unexpected peel seal sheath 103.
When first adhesive segment 110 is stripped to its bottom margin gradually, first adhesive segment 110 peel off end.When peeling off of first adhesive segment 110 finished, between the corresponding surface of first adhesive segment 110 and cartridge body 101, overcome it and apply power by the user and become zero with the adhesion strength of peel seal sheath 103.Therefore, do not have the expection of peeling off end of sealing sheath 103, peel off the instantaneous of end in first adhesive segment 110, user's hand may unclamp suddenly on by the arrow B indicated direction.By the adhesion strength between the corresponding wall that is adjusted in first adhesive segment 110 and cartridge body 101, can prevent to hold this problem that the user's of sealing sheath 103 hand unclamps suddenly in the direction of arrow.
With reference to Fig. 6, after peeling off of first adhesive segment 110 finished, the mode of rotating with edge (the center of rotation C in Fig. 6) around second adhesive segment 110 of the most close ink outlet 102, remove by sealing sheath 103 from ink outlet 102 and to remain on cover piece 121 position of its sealing ink outlet 102, open ink outlet 102.As mentioned above, during removing this process of cover piece 121, the motion of user's hand keeps control well, and promptly user's hand can not move suddenly.Therefore, the ink between ink outlet 102 and cover piece 121 it splash when quickening by the unexpected motion of the kinetic suddenly sealing sheath 103 of user's hand rather than keep adhering to ink export 102 and/or cover piece 121 on phenomenon can not take place.And, to zero reduce suddenly, make the essential power of peel seal sheath 103 user might feel finishing that ink outlet 102 opens.
And, when using this open method, 111 of second adhesive segment are used for preventing that sealing sheath 103 from peeling off suddenly, promptly prevent to cause ink spattering on the sealing surfaces of cover piece 121, the effect of block, therefore prevent the splashing of ink on the sealing surfaces of cover piece 121.With reference to Fig. 6, in order to make block, or second adhesive segment 111, in the purpose that opening the ink outlet, works, the bottom margin of wishing adhesive segment 111 with on the surface of the cartridge body 101 of second adhesive segment 111 that it is bondd, and have coincident between the surface that ink exports 102 cartridge body 101.And, after ink outlet 102 is opened, play block in order to make second adhesive segment 111 as quickly as possible, ink export 102 should the phase adjacency pair its be bonded with the surface arrangement of the cartridge body 101 of adhesive segment 111.And, stop to peel off action in order to guarantee second adhesive segment 111, should be in the adhesion strength between the corresponding surface of second adhesive segment 111 and cartridge body 101 greater than the adhesion strength between the corresponding surface at first adhesive segment 110 and cartridge body 101.As long as second adhesive segment 111 plays link stopper immediately reliably after peeling off of first adhesive segment 110 finished, cover piece 121 remains close to ink outlet 102, almost directly exports 102 opening facing to ink.Therefore, if ink splashes from cover piece 121, the ink that splashes flies in the cover piece 121, is trapped in wherein, and therefore, prevents to sputter cover piece 121 and sealing sheath 103.In order to make second adhesive segment 111 more effectively play block, designed this embodiment of print cartridge or print cartridge 100 like this, thereby in fact the direction of pulling sealing sheath 103 before ink outlet 102 begins to open just wherein becomes the surface perpendicular to the cartridge body 101 that has ink outlet 102.This is for following reason.In the moment of peeling off of first adhesive segment 110 of finishing sealing sheath 103, change into this power of on the direction of shearing second adhesive segment 111, working peeling off the power that first adhesive segment 110 applies.Thereby, design described above be used for making remove second adhesive segment 111 quite the difficulty.Secondly, with reference to Figure 13 (a) and 13 (b), event when the user peels off first adhesive segment 110 in every way will be described.Figure 13 (a) represents print cartridge 100, and its sealing sheath 103 can extend on by arrow mark E indicated direction as far as possible far, and arrow mark E indicated direction parallels with the surface of the cartridge body 101 of first adhesive segment 110 that it had once been bondd.Figure 13 (b) represents print cartridge 100, and its sealing sheath 103 spurs on by arrow flag F indicated direction, and arrow flag F indicated direction is capable with air spots to the cartridge body 101 of its first adhesive segment 110 that once bondd.Even peel seal sheath 103 as shown in Figure 13 (a) or 13 (b), the distance (1) of the outlet 102 from cover piece 121 to ink is also regulated in the existence that plays second adhesive segment 111 of block effect.When the conventional sealing sheath (tape) that adopts as sealing device, after ink outlet 102 is opened, can not be adjusted in cover piece 121 and ink and export distance between 102.Relatively the time, when adopting according to sealing sheath 103 of the present invention, cover piece 121 time per units (t) can be obviously less from the distances (1/t) of ink outlet 102 motions, makes to prevent ink spattering.
By means of providing of in this embodiment constructional device, if ink spattering, then sealing sheath 103 itself plays the ink grabber, makes the pollution minimum that comes from ink spattering.
After ink outlet 102 is opened, second adhesive segment 111 of peel seal sheath 103.Second adhesive segment 111 is vertical sealing sheath 103, strides across sizable scope and also is bonded on the cartridge body 101, just as first adhesive segment 110.Thereby user's peel seal sheath 103 gradually, feel to be used for the essential power of second adhesive segment 111 of peel seal sheath 103 simultaneously.During this process that second adhesive segment 111 is peeled off, can see the sealing surfaces of the cover piece 121 that has ink on it.Therefore, remind the also adhesive segment 111 of peel seal sheath 103 carefully of user, up to removing sealing sheath 103 fully.
In this embodiment, first and second adhesive segment 110 and 111 widths according to sealing sheath 103 stride across gamut and are bonded on the cartridge body 101.Yet in order to reduce the amount in essential power of the starting stage that sealing sheath 103 is peeled off, they can bond in a different manner, as are illustrated in a kind of among Figure 12; A kind of like this employing of mode can not cause problem.
For the ink outlet 102 of opening this embodiment of the present invention, promptly print cartridge 100, and desired user action is, only peel seal 105 and peel seal sheath 103 are as shown in Fig. 5 (a)-5 (d).In two actions, peeling off them desired is to hold fin or flap-like part, and spurs it; In other words, anyone can easily open ink outlet 102.

Secondly, with reference to Fig. 7, with second embodiment that describes according to print cartridge of the present invention.
Fig. 7 represents second embodiment according to a kind of print cartridge of the present invention.Fig. 7 (a) is the stereogram of the print cartridge under opening; And 7 (b) are the stereogram of its ink outlet with the print cartridge of sealing sheath sealing.
By the print cartridge of describing among Fig. 7 to construct 100 are a kind of liquid containers that can hold three kinds of inks of different colours in its cartridge body 101, have three ink outlets 102.Print cartridge 100 has three three chambers being separated by rib.Each chamber is filled with negative pressure force generating member (Fig. 2), holds the ink different with the ink color in other chamber.Cartridge body 101 is forms of cuboid, and vertical dimension is greater than horizontal size, as shown in Figure 7.
Sealing sheath 103 is formed by rubber, and is U-shaped.This embodiment of print cartridge 100 is more flat, and sealing sheath 103 strides across three surface coverage print cartridges 100: the maximum surface that has the surface of ink outlet 102 and the surface that clamping has ink outlet 102 is to (with the surface of the surface adjacency that has the ink outlet).The direction of wherein placing sealing sheath 103 need not be restricted to the direction of the sealing sheath 103 of wherein placing this embodiment; For example, sealing sheath 103 except that maximum surface to, can stride across the surface that has the ink outlet and with the surface of the surface adjacency that has the ink outlet to placing.Sealing sheath 103 has first and second adhesive segment 110 and 111, these adhesive segment are so located, thereby when being placed on sealing sheath 103 on the print cartridge 100, they with the surface of the cartridge body 101 of the surface adjacency of the cartridge body 101 that has ink outlet 102 to (maximum to) on.First and second adhesive segment 110 and 111 are adhered on the corresponding surface of cartridge body 101.Sealing sheath 103 is formed by elastic caoutchouc.Therefore, sealing sheath 103 can be adhered on the cartridge body 101 under extended configuration, thereby ink outlet 102 is sealed airtightly by cover piece 121.Even this print cartridge 100 has three ink outlets, all three ink outlets 102 can not cause any problem with single cover piece 121 sealings yet.The method that is used for opening ink outlet 102 is identical with the method that the ink that is used for opening first embodiment of the invention exports; Sealing sheath 103 is peeled off on the arrow mark D indicated direction in by Fig. 7 (b).
Picture first embodiment, this embodiment can prevent ink outlet 102 and ink between the cover piece 121 when it is quickened by the unexpected motion of the kinetic sealing sheath 103 of the wrench of user's hand, splash rather than keep adhering to ink export 102 and/or cover piece 121 on phenomenon.And second adhesive segment 111 is reinstated the effect of the block of peeling off action of temporarily ending the user, therefore prevents the ink spattering on the sealing surfaces of cover piece 121.
(embodiment 3)
Secondly, with reference to Fig. 8, with the 3rd embodiment that describes according to print cartridge of the present invention.
Fig. 8 is the stereogram according to the third embodiment of the present invention, and its outlet seals with sealing sheath.
The print cartridge of representing in Fig. 8 100 has two chambers: an ink storage chamber and be filled with the negative pressure force generating member storage chamber of negative pressure force generating member.The cornice of ink storage chamber has an ink outlet (not shown), and its opening is filled with a filter (not shown).
Sealing sheath 103 is formed by film, and is U-shaped.This embodiment of print cartridge 100 is more flat, and sealing sheath 103 strides across three surface coverage print cartridges 100: the maximum surface that has the surface of ink outlet 102 and the surface that clamping has ink outlet 102 is to (with the surface of the surface adjacency that has the ink outlet).Right each in maximum surface has a step.Wherein sealing sheath 103 is placed on the direction that direction on the cartridge body 101 need not be restricted to the sealing sheath 103 of placing this embodiment; For example, sealing sheath 103 except that maximum surface to, can stride across the surface that has the ink outlet and with the surface of the surface adjacency that has the ink outlet to placing.Sealing sheath 103 has first and second adhesive segment 110 and 111, these adhesive segment are so located, thereby when being placed on sealing sheath 103 on the print cartridge 100, they with the surface of the cartridge body 101 of the surface adjacency of the cartridge body 101 that has ink outlet 102 to (maximum to) on.First adhesive segment 110 and stride across cartridge body 101 second adhesive segment 111 vis-a-vis spots weld on the corresponding surface of cartridge body 101.The method that is used for opening ink outlet 102 is identical with the method that the ink that is used for opening the present invention first and second embodiment exports; Sealing sheath 103 is peeled off on the arrow mark E indicated direction in by Fig. 8.
Sealing sheath 103 is peeled off as follows.With reference to Fig. 8, at first, on by the arrow E indicated direction, spur adhesive segment 110.The user should be understood that should be gradually rather than peel seal sheath 103 suddenly, because at a plurality of somes 110a places in alignment on the length direction of sealing sheath 103 first adhesive segment 110 is spoted weld on the surface of cartridge body 101.When the user peeled off first adhesive segment 110 gradually, the user can know from experience the power (stress) of the essential appropriate amount of peel seal sheath 103, can prevent a large amount of excessively power that causes sealing sheath 103 to be peeled off suddenly that applies.
When first adhesive segment 110 being stripped to gradually and continuously it with bottom margin that the bottom margin of cartridge body 101 overlaps, first adhesive segment 110 peel off end.First adhesive segment 110 peel off end in, between the corresponding surface of first adhesive segment and cartridge body 101, the adhesion strength with peel seal sheath 103 becomes zero on sealing sheath 103 so that power is applied to overcome it.Therefore, not in the expection of the drag losses of peeling off the adhesion strength between the corresponding wall that end comes comfortable first adhesive segment 110 and cartridge body 101 of first adhesive segment 110 of sealing sheath 103, first adhesive segment 110 peel off end in, because drag losses, user's hand may unclamped suddenly by the arrow E indicated direction.Peel off first adhesive segment 110 in its time and need not under the level of a large amount of power by the adhesion strength between the corresponding wall of first adhesive segment 110 and cartridge body 101 is set to, can avoid holding this problem that the user's of sealing sheath 103 hand unclamps suddenly in the direction of arrow.
With reference to Fig. 6, after peeling off of first adhesive segment 110 finished, in the mode of rotating around the pad (not shown) of second adhesive segment 110 of the most close ink outlet 102, remove by sealing sheath 103 from ink outlet 102 and to remain on cover piece 121 position of its sealing ink outlet 102, open ink outlet 102.As mentioned above, during removing this process of cover piece 121, the motion of user's hand keeps control well, and therefore the situation of ink outlet 102 can not take place to open suddenly.Therefore, the ink between ink outlet 102 and cover piece 121 by quicken by the unexpected motion of the kinetic suddenly sealing sheath 103 of user's hand and splash rather than keep adhering to ink export 102 and/or cover piece 121 on phenomenon can not take place.And the unexpected loss that comes the resistance of the adhesion strength between comfortable first adhesive segment 110 and the cartridge body 101 makes the user might feel that ink exports finishing of 102 unlatchings.
Picture first and second embodiment, this embodiment also can prevent the open period of ink outlet 102 first adhesive segment 110 peel off end's wrench sealing sheath 103, therefore prevent between ink outlet 102 and cover piece 121 ink by quicken by the wrench of user's hand and splash rather than keep adhering to ink export 102 and/or cover piece 121 on phenomenon.And this embodiment also can prevent the splashing of ink on the sealing surfaces of cover piece 121.
(embodiment 4)
Secondly, with reference to Figure 14, the fourth embodiment of the present invention will be described.Except that sealing sheath 103 and seal 105, similar according to this embodiment and first embodiment of print cartridge of the present invention.Thereby, only about sealing sheath 103 and seal 105 and be used for opening method, this embodiment is described by the part of sealing sheath 103 and seal 105 sealings.Figure 14 (a) is the stereogram of this embodiment, and Figure 14 (b) is the side view of this embodiment.Figure 14 (c) is the front view of this embodiment.
At first, with reference to Figure 14, will the sealing sheath 103 of print cartridge 100 be described.Sealing sheath 103 comprises a take-up strap part 120 and sealing sheath 103 that is formed by the material identical materials with take-up strap part 120 that is used for first embodiment and sealing sheath 103.It twines around cartridge body 101.It is looked is enough to after twining once around cartridge body 101, from the surperficial almost parallel of cartridge body 101, promptly with the maximum surface of cartridge body 101 to vertical, cartridge body 101 extensible certain-lengths.It forms by a part of excising sealing sheath 103 with the form of fin.And, this sealing sheath 103 is equipped with two straight line eyelets 510, eyelet 510 extends one to one from the two ends (tearing apart initial point 510) of the foundation of fin 500 in such a way, thereby when when cartridge body 101 twines sealing shroud 103, two row eyelets arrive the actual bottom edge (tearing halt 512) of cartridge body 101.First and second adhesive segment 110 and 111 of this embodiment are basically the same as those in the first embodiment; They are located like this, thus when when cartridge body 101 twines sealing sheaths 103, they toward each other, clamping has on two side surfaces (with two surfaces of the surface adjacency that has print cartridge outlet 102) of cartridge body 101 on surface of ink outlet 102.
Secondly, seal 105 will be described.Seal 105 is squares, and is formed by film.It is bonded on the cartridge body 101, thus its sealing blow vent 104.Before being installed to print cartridge 100 in the ink jet recording device (not shown), should peel seal 105.Therefore, semi-permanent adhesive or thermal weld are used for sealing sheath 103 is fixed to device on the cartridge body 101.Seal 105 is fixed on the sealing sheath 103 by means of a kind of like this use or thermal weld method of adhesive, and this makes adhesion strength between seal 105 and sealing sheath 103 greater than remove the essential power of seal 105 from blow vent 104.Doing like this is for by single action, promptly realizes two purposes, the i.e. unlatching of the unlatching of print cartridge 100 and blow vent by the part of peeling off the sealing sheath 103 between two row eyelets simply.Unlatching details according to this embodiment of print cartridge of the present invention will be described later on.
Secondly, description is used for opening method according to this embodiment of print cartridge of the present invention.Open method will be described to the stage of opening blow vent, and not describe process thereafter, because they are with to be used for those of first embodiment identical.
Print cartridge is opened as follows.At first, the user holds the fin 500 of sealing sheath 103, and spurs it to cut off sealing sheath 103, simultaneously peel seal sheath 103 on the direction of twining sealing sheath 103 around cartridge body 101.Sealing sheath 103 is equipped with the two row eyelets 510 that cut off sealing sheath 103 along it easily.Two row eyelets 510 extend from the two ends (tearing apart initial point) of the bottom of fin 500.Thereby, when the user holds fin 500, and the direction pulling of twining sealing sheath 103 it the time, sealing sheath 103 is easily torn along eyelet 510, allows the parts of the sealing sheath 103 between two row eyelets 510 to peel off easily.During this process, the user can guarantee that he is own to correct direction peel seal sheath 103 by finding eyelet.
When the part of the sealing sheath 103 between two row eyelets was stripped to the position of seal 105, seal 105 beginnings were peeled off with cartridge body 101 and sealing sheath 103, expose blow vent 104.This be because in the adhesion strength between seal 105 and the sealing sheath 103 greater than the adhesion strength between seal 105 and cartridge body 101, and therefore, when peel seal sheath 103, seal 105 maintenances are bonded on the sealing sheath 103.Seal 105 is adhered on the cartridge body 101, firmly must be enough to keep blow vent 104 sealing.Thereby, when sealing sheath 103 is stripped to the position of seal 105, must increase the power that is applied on the sealing sheath 103 with peel seal sheath 103.Therefore, unless take certain measure, in complete peel seal 105, the user's of pulling fin 500 hand can become flexible suddenly and uncontrollably, peels off the part of its sealing sheath 103 after seal 105 suddenly.Yet, under the situation of this embodiment, first adhesive segment 110 of the end 512 of close eyelet 510 is arranged, and first adhesive segment 110 works to be used for controlling the block of motion suddenly of user's hand.In other words, first adhesive segment 110 can be ended peeling off to prevent following problem of sealing sheath 103 temporarily.Promptly, if open ink outlet 102, then for user's hand in the speed motion identical with the speed of its setting in motion owing to be applied on the fin 500 with the reducing suddenly of the resistance of the power of the part of peeling off the sealing sheath 103 that has seal 105 for the hand by the user, ink will splash.By means of the existence of first adhesive segment 110, can prevent the continuation of motion suddenly of user's hand.
Up to the above-mentioned stage, this open method can easily be carried out by anyone because must make whole be to hold and spur fin 500 with peel seal sheath 103.
Next, stripping process, the ink of carrying out first adhesive segment 110 exports 102 stripping process, reaches the stripping process of second adhesive segment 111.These processes and its effect are with identical for those of first embodiment; In other words, can open print cartridge 100 easily and the ink that do not splash.
Explanation in passing, the employing of seal 105 is not enforceable.In other words, blow vent 104 can directly be sealed by sealing sheath 103.
(embodiment 5)
Secondly, with reference to Figure 15, with the 5th embodiment that describes according to print cartridge of the present invention.Except that the sealing sheath 103 of this print cartridge 100 and the 4th embodiment different, this print cartridge 100 is similar with the present invention first and the 4th embodiment.Thereby only the part of the cartridge body 101 that covers about the part of the open method that relates to sealing sheath 103 with sealing sheath 103 is described this embodiment.Figure 15 (a) is the stereogram according to this embodiment of print cartridge of the present invention; Figure 15 (b) is its side view; Figure 15 (c) is its front view; And Figure 15 (d) is the cutting interval variation point of eyelet and near the zoomed-in view it of the sealing sheath 103 of this embodiment.
At first, with reference to Figure 15, it is own to describe sealing sheath 103.Sealing sheath 103 comprises by a take-up strap part 120 and a cover piece 121 of forming with those identical materials that are used for the first and the 4th embodiment.It comprises its fin 500 similar with the 4th embodiment in shape.Sealing sheath 103 is equipped with a pair of eyelet 510, eyelet 510 is on the direction parallel with the direction of twining sealing sheath 103 around cartridge body 101, extend from the end (starting point 511 of eyelet) of the bottom line of fin 500, looking is enough to arrive near (end point 512 of eyelet) of bottom margin with the surface of the cartridge body 101 of the surface adjacency of the cartridge body 101 that has passage 104, strides across two surfaces and extends.Each eyelet 510 has two different at interval parts of cutting.Two parts are put 513 places a cutting interval variation and are separated.In other words, tear apart initial point 511 and cutting between the interval variation point 513 part and at cutting interval variation point 513 and tear part between the end point 512, cutting difference aspect the interval, as shown in Figure 15 (d).That is, each cutting of the eyelet part between the interval variation point at interval 514 in starting point 511 and cutting, than each cutting of eyelet remainder at interval 515, promptly partly lack at cutting interval variation point 513 and the eyelet torn between the end point 512.Therefore, sealing sheath 103 is torn than the latter is easy along the former.By means of a kind of like this use of adhesive or the use of thermal weld method, seal 105 is fixed on the part of the sealing sheath between two eyelets 103, this makes in the adhesion strength between seal 105 and the sealing sheath 103 greater than the adhesion strength of (more particularly, the part around blow vent 104) between seal 105 and cartridge body 101.Adhesive segment 600 is so located, thereby according to the direction of peel seal sheath 103 wherein, the back edge of stick portion 600 is approximate to be overlapped with the end point 512 of each eyelet.Because when unlatching also release adhesive part 600 during print cartridge 100, so by means of the use of a kind of like this adhesive or thermal weld method, it is adhered on the cartridge body 101, this peels off adhesive segment 600 easily.
Secondly, will the method for opening according to the print cartridge of this embodiment of the present invention be described.Here, be described to the method for tearing the stage of sealing sheath 103 along eyelet of finishing.Because the process that is used for opening print cartridge 100 later on is with identical for those of first embodiment, so do not describe them.
In case in the position that advances to seal 105 of peeling off of the part of the sealing sheath 103 of two row between the eyelets 510, seal 105 is just peeled off exposure passage 104 from the parts of the sealing sheath 103 between cartridge body 101 and the two row eyelets.This is because seal 105 is bonded on sealing sheath 103 and the cartridge body 101 in such a way, thereby the adhesion strength between seal 105 and the sealing sheath 103 become greater than between seal 105 and cartridge body 101 (more particularly, part around passage 104) adhesion strength, and therefore, seal 105 remains fixed on the sealing sheath 103.
From the amount of the essential power of cartridge body 101 peel seal 105 greater than the amount of tearing the essential power of sealing sheath 103 along two row eyelets.Therefore, the user will apply relatively large strength in peel seal 105.Then, as long as complete peel seal 105, the amount of the power that peel seal sheath 103 is essential just reduces suddenly, although the user still applies strength in the amount with the essential power of peel seal 105.Thereby, unless take certain measure, user's hand can move in pulling sealing sheath 103 suddenly.Therefore, the part of the sealing sheath 103 between two row eyelets after seal 105 will be drawn back suddenly.Yet under the situation of this embodiment, every capable eyelet has the different at interval two parts of cutting.And the cutting interval variation point 513 that eyelet is divided into two at interval different parts of cutting is located like this, thus it with the surface of the cartridge body 101 of the surface adjacency of the cartridge body 101 that has blow vent 104 on.Therefore, put the part of 513 corresponding sealing sheaths 103 with the cutting interval variation, the effect of reinstating the block of the unlatching of ending print cartridge 100 temporarily, so prevent by move the suddenly wrench of the sealing sheath 103 that causes of user's hand above-mentioned.More particularly, cutting interval 514 in the part that tears apart the every capable eyelet between initial point 511 and the cutting interval variation point 513 is shorter, make and be easier to tear sealing sheath 103 along eyelet, and the cutting interval 515 in the eyelet part between cutting interval variation point 513 and end point 512 is longer, and the amount of the essential power of sealing sheath 103 is torn in increase along this part of eyelet.Thereby, by tear the difference of the essential power of sealing sheath 103 along eyelet between eyelet two parts, stop the peeling off suddenly of above-mentioned kinetic suddenly sealing sheath 103 of the hand by the user.In other words, the motion suddenly of user's hand will not continue to look is enough to peel off even exports the part of 102 corresponding sealing sheaths 103 with ink.Therefore, the problem of the ink that splashes that is caused by the unexpected unlatching of ink outlet 102 can not take place.
After the part by the sealing sheath 103 of the cutting interval variation point 513 that has eyelet stops to tear suddenly of sealing sheath 103, the user begins to peel off the part of the sealing sheath 103 between two row eyelets, the end point of sealing sheath 103 being torn eyelet 510 along eyelet simultaneously once more.As mentioned above, need the partially torn sealing sheath 103 of bigger power along the eyelet between cutting interval variation point 513 and end point 512, and make this part long enough on the direction of twining sealing sheath 103 around cartridge body 101, so that the user realize should significant care this part of ground peel seal sheath 103, promptly do not wrench.Then, the user gradually in this part of peel seal sheath 103, the user feels exactly and the size of the power that the remainder of peel seal sheath 103 is essential therefore prevents to apply excessive power; In other words, prevent user's remainder of peel seal sheath 103 suddenly.
When the part of the sealing sheath 103 between two row eyelets was stripped to the end points of eyelet 512, seal 103 lost its ring form.Thereby, suddenly disappearing for the resistance that is applied to by the user on the sealing sheath 103 with the power of peeling off it, this can cause that user's hand spurs the user on the direction of sealing sheath 103 and quicken suddenly.Under the situation of this embodiment, as mentioned above, the user is not applied to a large amount of excessively power on the sealing sheath 103.Therefore, even when resistance disappears, user's hand can not quicken suddenly yet.After peeling off of the part of the sealing sheath 103 of two row between the eyelets finished, open ink outlet 102.
As confirming by above description like that, put essential all according to this of the method for this embodiment of print cartridge of the present invention to being used for opening, be to hold fin 500 and spur it with peel seal sheath 103.Therefore, anyone can easily finish the work.
After this, carry out the process that is used for opening the process of ink outlet 102 and is used for peeling off adhesive segment 600.These processes and its effect are with identical for those of first embodiment; In other words, can open print cartridge 100 easily and the ink that do not splash.
As mentioned above, the present invention relates to be used for a kind of liquid container sheath of liquid outlet of sealing liquid container.One of each characteristic aspect according to the present invention, the liquid container sealing sheath is equipped with: minimum two parts (first to fourth embodiment) are fixed to it on the liquid container by these two parts; Or the combination of an adhesive segment and a tear-off device (the 5th embodiment), need the power of scheduled volume to tear it, they are independently arranged in the mode of the liquid outlet of clamping liquid container according to the direction of peel seal sheath.Therefore, the length (first embodiment) of length of the adhesive segment of at first peeling off (first to fourth embodiment) or tear-off device, make the user might discern the amount of the necessary power of peel seal sheath, prevent to apply a large amount of power thus and unexpected peel seal sheath.
According to another aspect of the present invention, be not bonded on the surface of liquid container with the part of the corresponding sealing sheath of liquid outlet on the position.Therefore, as long as finish first adhesive segment (first to fourth embodiment) of sealing sheath or peeling off of tear-off device (the 5th embodiment), just can open liquid outlet.As mentioned above, during this process, the phenomenon that sealing sheath is peeled off suddenly can not appear.Therefore, in liquid outlet or the phenomenon of liquid splash around it can not take place.And when the amount of peeling off essential power was reduced to zero suddenly, liquid outlet becomes opened the sensation of finishing of just opening liquid outlet for the user.
