At this moment, pore 6 is present in the same side of ink reservoir with ink supply port 5, thereby can realize the welding of seal 102 simultaneously.Shown in Figure 17 (c),, just can realize the state that can use according to the seal 102 of tearing from aperture 6 to the order of ink supply port 5 of leading to ambiance.(Figure 17 (c) is the profile along the B-B line intercepting of Figure 17 (e)).

Figure 17 (e) shows the clear pore 6 of having removed seal from it.

Ink reservoir 1 with said structure is installed on the tape deck 21, as shown in figure 18.

Tape deck 21 shown in Figure 180 is provided with the master component 22 and its beast of cover 23 of this device.This master component is provided with an operating portion with operating knob and indicator lamp, and one be used for carrying and hold ink reservoir 1 and the record head 11 (structure of being made of a tube box 111 at this equipment four record heads, be used to carry out colored record) balladeur train 25, the form that this balladeur train 25 can scan is moved in recording areas and non-recording areas.

In this device, the printing ink grain directed downwards of spraying by record head 1 is promptly towards the direction of gravity.These printing ink grains deposit in the face of balladeur train and the scanning by balladeur train and form on image or the records paper.

Above-mentioned record-paper is from the back supply of master component 22 and is transported to the front side.Sledge position shown in Figure 6 is the home position, promptly in this position of changing record head tube box 111 or changing ink reservoir 1.Be provided with one in corresponding position, home position therewith and be used for covering record head 11 and spray the cover of sides, this covers jet exit during covering on and not carrying out writing down.This cover is associated with being used for keeping the recovery device with recovery record 11, carries out the quality of holding the record of recovery operation by preset time.

When writing down, record head tube box 111 and ink reservoir held on balladeur train 25 and cover 23 and close in 1 year.Like this, near the scanning area the balladeur train 25 seals, and the paper ash that this balladeur train produced is floating in the space of this sealing.

But in ink reservoir of the present invention, paper ash is the outer orifice end that is difficult for entering pore.Because orifice end is provided in a side of under the inner orifice end in addition, paper ash or dust just are difficult for entering within the fluid passage that connects this inner orifice end and outer orifice end.Outer orifice end is downward-sloping to obtain further improvement to this result by making.

As mentioned above, pore particularly its outer orifice end is provided in a side of the position that a paper ash is difficult for entering, thereby can protect this aperture can not be paper ash or dust obstruction.

By making outer orifice end be located under the inner orifice end or make outer orifice end downward-sloping, so paper ash is with in dust just is difficult for entering the fluid passage that is connected inside and outside orifice end.Just can prevent printing ink to leak outside by the printing ink portion of damming is set, the printing ink that dams simultaneously just can moistening effectively air vent channel and stop inner printing ink evaporation.

The following describes the ink roller box of above-mentioned package-type.

Among Figure 19, (a) being the top plan view of the ink roller box in a packing, (b) is the profile along X-X line intercepting among the figure (a), and (c) is the profile along Y-Y line intercepting among the figure (a).

In above-mentioned each figure, label 101 refers to the master component of this ink roller box, and 102 refer to its ink supply port; 103 refer to pores, and 104 refer to the seal of sealing ink supply ports 102 and pore 103, and 105 are the packings that are used for this whole assembly 101.The inside of master component 101 has contained printing ink.In this example, this assembly comprises: admit the negative pressure generation part storage portion of next negative pressure generation part, be used for absorbing and keep printing ink and form fluids with ink supply port 102 and pore 103 being communicated with; And an ink containment portion that stores printing ink, it is contiguous that it is located at negative pressure generation part storage portion.

Around each ink supply port 102 and valve 103, be formed with the flange 103A of columnar flange 102A and rectangle.The diameter of ink supply port 102 equates substantially with the diameter of flange 102A inner peripheral surface, and greater than the diameter of pore 103.The thickness of flange 102A is greater than the protruding thickness that meets 103A, and dress is also adorned with a seal 104 on the end face of flange 103A simultaneously separably with a seal 104 separably on the end face of flange 102A.

On the other hand, seal 104 is to be made by a kind of barrier material with sufficient intensity of opposing tension force or similar external force, and has enough toughness.It can be the individual layer and the sandwich construction of plastic resin material film, and preferably good welding character can be arranged with respect to the end face of flange 102A, 103A.With seal 104 sealing ink supply port 102 and pores 103.This part that being used for of seal 104 seals ink supply port 102 is called " first sealing ", and this part that is used for sealing pore 103 is called " second sealing ".Two sealings of this of seal 104 only require that they can be sealed to ink supply port 102 and pore 103, and the expansion that makes it to withstand air in the master component 101 or printing ink can prevent the printing ink evaporation simultaneously just.Described seal can join on flange 102A, the 103A with the form or the bonding method of welding, crimping, also can adopt other method simultaneously.In order to ensure very high reliability is arranged, preferably the weld layer of similar material is used for master component 101, can improve weldability like this.The top 104A of seal 104 is welded on the inner surface of packing 105.In seal 104, be included in the dash area of the top 104A among Figure 19, be called " operating portion " C.

Packing 105 is got the bag shape that closes whole master component 101, and in this example, the neighboring part 106 of forming this bag form is that seam rises, and the operating portion C of seal 104 is part 106 seam therewith then.Packing 105 is only required that it can be connected with operating portion C by modes such as crimping, bonding or seam and just can.Pack similar that 105 material therefors can be with seal, or also can generally be used for the material of packaging field, for example paper.In this example, the weld layer of seal 104 and packing 105 are to weld with heat, form whole simultaneously.

The following describes the installation of seal 104.

Figure 20 (a)-(d) shows that clear seal 104 is welded to the ink supply port 102 of master component 101 and the operation on the pore 103.

A plain seal part 104 shown in Figure 20 of Zhun Beiing (a) at first.It is welded on the flange 103A of the pore of locating master component 101 bottoms 103 sealing pore 103 (Figure 20 (b)).Shown in Figure 20 (c),, be welded to again on the flange 102A of ink supply port 102 then seal 104 bendings.Then that seal 104 is folding along straight line 104B, shown in Figure 20 (c), simultaneously at the outer of master component 101 straight line 101A and 101B folding (Figure 20 (d)).After master component 101 and seal 104 are packaged in the packing 105 in this stage, just formed state shown in Figure 19.

In this ink roller box, ink supply port 102 and pore 103 are on the not ipsilateral of master component 101.Therefore, when the direction of arrow F1 in Figure 20 (d) was afterburning, second sealing in the pore portion 103 just was easy to peel off, and was to shear separating force but be used for the power that first sealing of ink supply port 102 received, thereby was difficult for peeling off.

The Kaifeng of ink roller box is described below.

Figure 21 (a)-(c) shows the Kaifeng process of understanding ink roller box of the present invention.

Before peel seal 104, along the chain line 105A among Figure 19 (a) packing 105 is torn, and the right side part of in same figure, removing package 105 from the part 108 of cutting.Figure 21 (a) shows clear this state.The left part of packing 105 is one to be used for preventing the part of printing ink sputter among Figure 21 (a), and holding end 109 be in end difference 109A by cutting off formation with 109B so that user's manipulation.When the direction of the grip part 109B of user by getting the projection form along arrow F1, when applying a separating force and coming to take out master component 101 from packing 105, the application point P of this separating force compares more close valve 108 with ink supply port 102.So the distance between this operating point P and the second sealing b is shorter than the distance between the operating point P and the first sealing a.

When gripping, the user firmly packs 105 and master component 101, and when direction of arrow F1 and F2 apply separating force, aforementioned first sealing is owing to the application point P away from power is difficult for peeling off, this separating force is in Figure 21 (a) direction left, promptly is perpendicular to direction of delaminate (direction up Fig. 2 (a)) from flange 102A.On the other hand, the second sealing b is then approaching with application point P, and separating force be with by the direction of separating on the flange 103 left-hand in (Figure 21 (a)) altogether, thereby it can be stripped from immediately.So the second sealing b will peel off prior to first sealing.

After the second sealing b peels off,, shown in Figure 21 (b), rotate according to the direction of arrow e around the S point simultaneously in the field of the first sealing a just master component 101 is withdrawn from from packing 105.Like this,, make the sealing of winning become identical with detaching direction F1, facilitate like this and separate first sealing from the detaching direction on the flange 102A just master component 101 rotates according to direction of arrow e shown in Figure 21 (c).Along with above-mentioned rotation, first sealing is promptly separated.

As a result, the second sealing b separated with flange 103A before first sealing is separated from flange 102A.Like this, pore 103 was just opened before ink supply port 102 breakdowns.There is certain relation between the order of unpacking and the sputter of printing ink.

When seal 104 separates following time, master component 101 promptly rotates as shown in figure 21 rather than moves linearly, thereby can avoid because the corresponding master component 101 that printing ink can not be followed container is done linearity motion fast the printing ink leakage problem that produces because of the inertia force of printing ink itself at places such as ink supply ports 102.If this kind problem takes place, the oil spill China ink can pollute user's hand.

More than explanation is applicable to ink reservoir shown in Figure 2.
