Therefore, the blade body 54 rotates integrally with the bolt 56 while maintaining the screwed state with the bolt 56 in a state where the pressing screw 57 is screwed back in the direction to cancel the pressure contact with the side surface of the blade body 54. Thus, the angular position of each blade portion 55 in the rotation direction around the axis of each blade body 54 can be changed and adjusted.

  In addition, when the bolt 56 is rotated in the screwing direction while the pressing screw 57 is in pressure contact with the side surface of the blade body 54 and the rotation of the blade body 54 is restricted, only the bolt 56 moves, and the bolt The heads of 56 are displaced in a direction (upward in FIG. 5B) to be lifted from the base portion 41. When the pressing screw 57 is loosened from this state, the bolt 56 and the blade body 54 that are integrated by the male screw portion 58 and the female screw hole 59 being screwed together are lowered by the amount that the head of the bolt 56 is lifted. However, the amount of protrusion of the blade body 54 from the lower surface of the base portion 41 is changed. In this state, if the pressing screw 57 is rotated again in the tightening direction and brought into pressure contact with the side surface of the blade body 54, the blade body is in a state where its rotation and movement in the vertical direction (axial direction) are restricted. .

  Then, the ink injection hole 21 and the opening 20 in the used ink cartridge 11 are used for the ink injection to the cover film 31 sealing the ink injection holes 21 and the opening 20 using the hole forming jig 40 configured as described above. A method for drilling holes will be described with reference to FIGS. 6 (a) and 6 (b).

  When the cover film 31 is punched, the used ink cartridge 11 is placed upside down as shown in FIG. In this case, the film member 32 has already been peeled off from the ink supply port 23. Then, the pair of blade portions 55 are located above and below the covering regions of the ink injection holes 21 and 22 in the cover film 31 so that the perforating jig 40 faces the lower surface of the ink cartridge 11 facing upward. Arranged to correspond in direction.

  Next, the pressing screw 57 is loosened to adjust the angular position of each blade 54 in the rotational direction, and the bolts 50 are loosened to adjust the positioning in the notch 47 of each block 48. . That is, when the drilling jig 40 approaches the ink cartridge 11 side and the blade portion 55 of each blade body 54 is pushed into the cover film 31 from the arrangement state, the blade portion 55 of the blade body 54 is desired. The pre-adjustment is performed so that the cut in the direction to be inserted can be made in the cover film 31 and not to enter the ink injection holes 21 and 22 deeper than necessary. In addition, as described above, the degree of entry of the blade body 54 into the ink injection holes 21 and 22 is adjusted by alternately rotating the bolts 56 and the pressing screws 57 as described above. It is also possible to cope with this by changing the protrusion amount.

  When the above pre-adjustment work is completed, the hole making jig 40 is moved closer to the ink cartridge 11 side. Then, the punching jig 40 has the inner surfaces 45 of the leg portions 44 in sliding contact with the left and right side surfaces of the ink cartridge 11, and the inner surfaces 46 of the joining plates 43 in sliding contact with the front and rear surfaces of the ink cartridge 11. The inner surface of the left notch 47 is in sliding contact with each guide wall 23a of the ink supply port 23 of the ink cartridge 11, and its moving direction is guided.

  Just before each block 48 comes into contact with the lower surface of the ink cartridge 11 that faces the container body 12 and the front end of the ink supply port 23, the blade portion 55 of each blade body 54 corresponds to each ink injection hole in the cover film 31. 21 and 22 are covered. Then, four cuts extending in the radial direction from one point corresponding to the center of each ink injection hole 21, 22 are formed in a cross shape in the cover film 31 by the blade portion 55 of each blade body 54. Thus, the punching jig 40 which is a cut member of the cover film 31 has substantially the same cross-sectional shape in the direction perpendicular to the direction of the punching jig 40 when the punching jig 40 is inserted into the cover film 31. Since the blade body 54 has a shape (a cross shape in this embodiment) that forms a cut in the shape in the cover film 31, the cover film 31 is formed with a cross-shaped cut similar to the blade body 54. The

  Then, four cantilevered sections 60 having the same shape are formed by the formation of the cross-shaped cuts, and the sections 60 are dispersed and drooped into the ink injection holes 21 and 22 so as to be separated in the radial direction. As a result, holes 61 are formed in the covering regions of the holes 21 and 22 in the cover film 31 as shown in FIG. At this time, the perforating jig 40 is configured such that each blade 48 abuts on the lower surface of the ink cartridge 11 facing upward of the container body 12 and the tip of the ink supply port 23, so that each blade body 54 further extends. Intrusion into the ink injection holes 21 and 22 is suppressed. In this regard, in the present embodiment, each block 48 as a displacement member functions as a restricting portion.

  Thereafter, an ink injection nozzle (not shown) is inserted into the ink injection holes 21 and 22 through the holes 61, and ink is refilled into the ink storage chambers 29 and 30 with which the ink injection holes 21 and 22 communicate. The When the ink refilling is completed, the hole 61 opened for the refilling is sealed by the sealing member, and the reusable ink cartridge 11 is regenerated.

Then, the sealing method which seals again with the sealing member by making the hole 61 opened in the cover film 31 into a sealing object opening is demonstrated referring FIG.
As shown in FIG. 7, when sealing the hole (sealing target opening) 61 of the cover film 31, a laminated film (sealing member) 70 having a two-layer structure is placed on the cover film 31. The The laminated film 70 includes a first film 71 that is melted at a predetermined heating temperature and a second film 72 that is not melted at the melting temperature of the first film 71 and has higher heat resistance than the first film 71. It has the structure made. That is, in the laminated film 70, the first film 71 constitutes the outermost layer on one side in the laminating direction of both films 71 and 72, and the second film 72 constitutes the outermost layer on the other side.

  When the laminated film 70 is placed on the cover film 31, each ink injection hole 21 is formed on the container body 12 such that the first film 71 is located on the container body 12 side and is in contact with the cover film 31. , 22 and the two holes 61 corresponding respectively. Here, the reason why the first film 71 is brought into contact with the cover film 31 with the container body 12 side is to melt the first film 71 by heating at the time of sealing so that the welding function is exhibited. The reason for positioning on the outer surface side is to maintain the sealing function with the second film 72 having excellent heat resistance.

  The first film 71 may be a polyolefin (PO) film, an ester film, or a film having an easy peel open (EPO) function that melts at a predetermined heating temperature and exhibits a good welding function. It can be adopted. In the case of a film having an EPO function, after the laminated film 70 is bonded onto the cover film 31 by the welding function, it is easily peeled off from the cover film 31 when necessary to expose the hole 61 again (easy Peel open).

  On the other hand, the second film 72 does not melt at the heating temperature at which the polyolefin (PO) film or the like is melted, and is more excellent in heat resistance than the polyolefin (PO) film or the like (polyethylene terephthalate ( PET) film. Further, the thickness of the first film 71 that is laminated with the second film 72 is set to 40 ··· within a range of 20 to 60 · F. The reason why the thickness of the first film 71 is set to 20 · net is to be able to cope with the case where the unevenness of the joint surface of the second film 72 with the first film 71 is melted. The reason why the thickness is reduced to 60 · net is that when the thickness is increased unnecessarily, the cost is increased and the heat conduction during heating is also deteriorated.

  Then, when the laminated film 70 is placed on the cover film 31, next, as shown in FIG. 7, a heater 73 serving as a heating unit is lowered toward the laminated film 70 from the laminated film 70. The heater 73 is heated to a predetermined temperature such that the first film 71 of the laminated film 70 is melted but the second film 72 is not melted, and the shape thereof is the surface of the laminated film 70 (the second film 72 of the second film 72). It is composed of a block body having a flat pressing surface that can be brought into surface contact with the surface.

  Therefore, as shown in FIG. 7, when the heater 73 is in surface contact with the surface of the laminated film 70 and heats the laminated film 70, only the annular region along the periphery of the hole 61 of the cover film 31 in the laminated film 70 is used. First, the portion of the covering region of the hole 61 that is the inner region is also heated. Therefore, the annular region along the periphery of the hole 61 is reliably melted and welded by heating, and the covered region of the hole 61 inside the annular region is similarly heated. The intensity change due to the heating of 71 can be similarly performed between the respective areas, and the occurrence of the intensity difference between the areas is suppressed.

  The laminated film 70 is firmly welded to the cover film 31 when the first film 71 is melted by the heating of the heater 73, and the sealing function is achieved by covering the hole 61 formed in the film 31. Will come out. Thereafter, when the heater 73 rises from the contact position indicated by the solid line in FIG. 7 to the standby position indicated by the two-dot chain line, the ink cartridge 11 that is reusable and reusable is obtained after the sealing process is completed.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) The hole 61 opened in the cover film 31 by the punching jig 40 is formed by the cantilevered sections 60 formed by the cross-shaped cuts in the film 31 depending on the ink injection holes 21 and 22. Since it is formed, broken material does not come out from the cover film 31. Accordingly, since no broken material is mixed into the ink injected for refilling through the hole 61 formed in this way, a flow path (for example, a narrow channel) in the ink cartridge 11 to be reused. The possibility of clogging in the flow path 21a, the narrow inlet 21b), and the like can be suppressed, and the ink cartridge 11 can be suitably regenerated.

  (2) A hole 61 is formed in the covering region of the ink injection hole 21, 22 in the cover film 31 by the hole making jig 40 so that the center thereof matches the center of the ink injection hole 21, 22 without any bias. Therefore, the ink can be easily refilled through the hole 61.

  (3) A clean hole with each piece 60 that hangs down in each ink injection hole 21, 22 in the radial direction within the covering region of each ink injection hole 21, 22 in the cover film 31 by the punching jig 40. Since 61 can be opened, an ink injection nozzle or the like can be easily inserted into the hole 61, and the ink refilling operation can be easily performed.

  (4) When the hole 61 is made by cutting the cover film 31 with the hole making jig 40, the peripheral edges of the ink injection holes 21 and 22 in the container body 12 are not damaged, and this point is also clogged. It is possible to suppress the generation of broken material that causes the Further, since it is possible to prevent the slices 60 formed by the cut formation from drooping into the ink injection holes 21 and 22 for a long time, for example, the slice 60 in which the narrow channel 21a or the narrow inlet 21b in the first ink injection hole 21 is drooped. It is also possible to prevent the ink from being clogged, and the ink can be refilled satisfactorily.

  (5) The drilling jig 40 is configured so that each blade portion 55 at the tip of the blade body 54 has its one point as a vertex as it is away from the one point in the radial direction from one point passing through the axial center of the blade body 54. 54 is formed so as to extend to the proximal end side of the blade 54, and the intersection of the blade portions 55 is sharpened, so that the tip of the blade body 54 can be sharply pushed into the cover film 31 when drilling. it can. Accordingly, it is possible to make a clean hole 61 by cutting the cover film 31 without generating broken material, and it is not necessary to drive the blade body 54, so that the hole can be easily drilled. .

  (6) In the drilling jig 40, the block 48 that functions as a restricting unit allows the blade portion 55 of the blade body 54 to enter the ink injection holes 21 and 22 of the container body 12 more than necessary when drilling. It can suppress by contacting the container main body 12 side. Therefore, it is possible to prevent the container body 12 from being damaged by the blade portion 55 that has entered too much, and to make the hole 61 having the same size every time the hole is made.

  (7) Further, the position of each block 48 functioning as a displacement member within the notch 47 is changed and adjusted by rotating the bolts 49 and 50, whereby the blade portion 55 of the blade body 54 with respect to the cover film 31. Can be adjusted, and the size of the hole 61 to be formed can be changed. Further, if the bolt 50 is not rotated, the hole 61 having a constant size can always be formed.

  (8) The drilling jig 40 can change the extending direction of the cut formed by each blade portion 55 by loosening the pressing screw 57 as an adjustment mechanism and adjusting the angular position of the blade body 54 in the rotational direction. It is also possible to adjust the position at which each section 60 hangs down into the ink injection holes 21 and 22. That is, the hanging position of each segment 60 can be adjusted according to the position of the flow path 21a and the ink inlet 21b in the ink injection holes 21 and 22.

  (9) The punching jig 40 is configured so that the inner surfaces 45 of both the leg portions 44 and the inner surfaces 46 of the both joining plates 43 are inserted in the cover film 31 when the blade body 54 pushes the tip into the cover film 31. It functions as a guide part that guides along a direction orthogonal to 31. Therefore, at the time of drilling, the blade portion 55 of the blade body 54 can be always pushed into the same position in the covering region of the ink injection holes 21 and 22 in the cover film 31, and at the same position every time the hole is drilled. On the other hand, a hole 61 can be formed.

  (10) When sealing the hole 61 as an opening to be sealed opened in the cover film 31, the first film 71 of the laminated film 70 is melted by heating to exhibit a welding function and the second film 72. Can exhibit heat resistance and ensure good sealing performance. Therefore, it is possible to obtain the ink cartridge 11 that ensures a good sealing property.

(11) When the first film 71 is formed of a film having an easy peel function, the first film 71 can be easily opened as necessary after the laminated film 70 is sealed.
(12) Since the thickness of the first film 71 is set to 20 to 60 · no, when the first film 71 is melted by the heating of the heater 73, the first film 71 is joined in the thickness direction. Even when the joining surface of the second film 72 has fine unevenness, the unevenness can be dealt with and the cost of the laminated film 70 can be suppressed.

  (13) Since the first film 71 of the laminated film 70 is melted and welded with certainty by heating the annular regions along the peripheral edges of the ink injection holes 21 and 22, the sealing function can be satisfactorily exhibited.

  (14) Further, the first film 71 of the laminated film 70 is heated in the same manner in both the annular region along the periphery of the ink injection holes 21 and 22 and the covering region of the ink injection holes 21 and 22 inside. The strength change due to the heating can be made in the same manner, and by suppressing the occurrence of the strength difference between the regions, the sealing performance can be exhibited uniformly.
