However, the position of the base 3 is fixed to the outer container 3.

Next, an ink container accommodating device (for example, described in Japanese Utility Model Publication No. 7-26133) of a printing machine, particularly a stencil printing machine, to which the ink container of the present invention is preferably applied will be described.

FIG. 6 is a front view showing an ink container storage device of the printing machine, and FIG. 7 is a sectional view taken along line ZZ of FIG.

6 to 7, C is an ink container of the present invention, and 30 is a pedestal of the ink container C in the printer body. The pedestal 30 is rotatably and slidably attached to the two shafts 31 and 32 on the printer main body side. The shafts 31, 32 are fixed to the fixing plates 33, 34 on the main body of the printing machine so as to face each other, project a predetermined amount, and are coaxially arranged and fixed. Both end flange portions of the base plate portion 35 of the pedestal 30 are supported by both shaft bodies 31 and 32 via slide bearings 36 and 37. As a result, the pedestal 30 is rotatably supported around both shafts 31, 32 and is supported in a sliding manner in its axial direction.

Further, a frame plate 38 that receives the ink container C, supports the outer container B thereof, and positions the ink container C is erected in the central portion of the pedestal 30. A U-shaped cutout for engaging and positioning the flange portion 3 of the ink container C on the side surface portion of the frame plate 38 on the ink pump 39 side is engaged and disengaged with the collar portion 3 formed on the outer peripheral surface of the mouth portion 3. The notch portion 41 is formed as an engaging portion. The suction port 40 of the ink pump 39 is arranged so as to face the cutout portion 41, and the base portion 3 of the ink container C is set coaxially with the suction port 40 of the ink pump 39. It

The tip portion of the suction port 40 is formed in a tapered shape, and the mouthpiece portion 3 of the ink container C is liquid-tightly fitted and connected to the suction port 40. .

Furthermore, a compression coil spring 42 is attached to the shaft body 32. The urging force of the compression coil spring 42 urges the pedestal 30 as a whole in the direction of the arrow a, that is, in the direction in which the cap portion 3 of the ink container C approaches the suction port 40 side of the ink pump 39.

A sliding guide 43 of the pedestal 30 is provided on the fixed plate 33 so as to project toward the pedestal 30 side. An inclined cam surface 44 is formed on the lower surface side of the sliding guide body 43, and a sliding piece 45 that comes into contact with the inclined cam surface 44 is projectingly provided on the pedestal 30 side. When the pedestal 30 is rotated in the direction of the arrow c on the front side, the sliding piece 45 slides on the inclined cam surface 44, and this operation causes the entire pedestal 30 to resist the compression coil spring 42. Then, it is pressed and moved in the axial direction of arrow b. When the cradle 30 is rotated in the direction of the arrow d on the depth side, a gap is created between the sliding piece 45 and the inclined cam surface 44, which causes the cradle 30 to move toward the compression coil bar. It is pushed back in the axial direction (the direction of arrow a) according to the urging force of the shaft 42.

The pedestal 30 is adapted to be rotated in conjunction with a cover (not shown) on the printer body side. That is, the hook portion 46 shown in FIG. 7 is engaged with the cover side, the ink container C stands up when the cover is fully closed, and the ink container C tilts toward the front side when the cover is fully opened. .

In the ink container accommodating device having such a configuration, when replacing an empty ink container with an ink container filled with ink, first open the cover of the printer main body and Interlockingly, the pedestal 30 is rotated toward the front side (direction of arrow c), and the empty ink container C is also inclined toward the front side. At this time, the sliding piece 45 of the pedestal 30 moves to the most opened position of the inclined cam surface 44 of the sliding guide body 43, so that the entire pedestal 30 resists the compression coil spring 42. It is pushed to the right side of 6. As a result, the mouthpiece portion 3 of the ink container C is held at a position separated from the suction port 40 of the ink pump 39. In this state, the empty ink container C is pulled out and removed.

Next, an operation of inserting and mounting the ink container C filled with ink will be described. While inserting a portion of the base portion 3 of the ink container C between the collar 5 and the side wall 2 of the inner container A into the U-shaped notch portion 41 formed in the frame plate 38 of the pedestal 30 and engaging them, When the ink container C is set at a predetermined position on the frame plate 38 and the main body cover is closed, the pedestal 30 is rotated to the depth side (the direction of arrow d) accordingly, and the ink container C stands upright. Along with the rotation of the pedestal 30 at this time, a gap is created between the sliding piece 45 and the inclined cam surface 44 of the guide body 43. Therefore, the pedestal 30 is mounted on the compression coil panel 42. It is pushed back by the urging force in the left direction of FIG. 6 (direction of arrow a). As a result, the mouthpiece portion 3 of the ink container C moves coaxially with the suction port 40 of the ink pump 39, and is fluid-tightly fitted and connected to the suction port 40 of the ink pump 39. When the ink pump 39 is driven in this state, the ink in the ink container C is sucked by the ink pump 39 and sent to the printing section.

When the ink container C of the present invention is set on the frame plate 38, even if the side surface of the outer container B from which the mouthpiece part 3 is projected is completely open, the position of the mouthpiece part 3 is outside. Since it is fixed to the container B 1, it is easy to engage the base 3 with the U-shaped notch 41 of the frame plate 38. Since the inside of the inner container A can be visually recognized from the opening surface of the outer container B by appropriately opening the cover of the printing machine, the ink remaining amount can be easily confirmed. Also, since the color of the ink can be checked when replacing the ink, it is possible to prevent the ink container containing wrong color ink from being installed by mistake.

The molded body 1 constituting the inner container A of the present invention has rigidity and does not easily deform. Here, the phrase “having rigidity and not easily deformed” means a material that does not easily deform during handling or when ink is sucked by an ink pump and can retain its original shape.

Hard plastics are usually used as the material of the molded body 1, and specific examples thereof include polypropylene, polyethylene, polyamide, polyester, polyvinyl chloride and the like.

The bag-shaped molded body 10 constituting the inner container A of the present invention has a certain shape when an external force is not applied, but can be easily deformed when an external force is applied. Here, the term “deformable easily” means that the ink can be deformed as the amount of the ink decreases when the ink is sucked by the ink pump, and finally the entire inner peripheral surface of the inner container A can be almost contacted. Say. Since the bag-shaped molded body 10 can be easily deformed as described above, the ink in the inner container A can be almost completely sucked out. As the material for the bag-shaped molded body 10, soft plastics are usually used, and specific examples thereof include polyethylene, polyamide, polyvinyl alcohol, polyvinyl acetate and the like.

In order to allow the bag-shaped molded body 10 to substantially contact the entire inner peripheral surface of the molded body 1 in a state where the ink in the inner container A is almost completely exhausted, the molded body 10 is also treated as the molded body 1. It is preferable that the hexahedrons have substantially the same dimensions and the inner volumes are substantially the same.

The molding 1 and the molding 10 can be joined by various methods, but normally, as shown in the above-mentioned embodiment, a flan extending outwardly over the entire circumference of the open edges of the moldings 1 and 10. It is preferable from the standpoint of bonding strength that the flange portions 8 and 11 are provided and the flange portions 8 and 11 are bonded to each other. As a joining means, a means such as adhesion using an adhesive or welding is appropriately adopted.

As in the present invention, when approximately half of the inner container A on the side having the mouthpiece 3 is made of a rigid molded body, in the case where the inner container in the conventional example has a substantially whole bag shape, When suctioning high-viscosity ink, the bag is constricted near the base, making it difficult to suck ink.

The outer container B is not particularly limited as long as it is made of a rigid material, but an assembling container of cardboard is preferably used because it is usually easy to print for design and marking.

In the present invention, the notch 21 is formed in the side wall of the outer container B, and the tongue piece 22 formed at that portion is fixed to the outer peripheral surface of the housing part 1 of the inner container A, so that the container A Is fixed to the outer container B. Appropriate means can be adopted as the fixing means of the tongue piece 22, for example, a method of raising the tongue piece 22 and applying an adhesive to the back surface of the tongue piece 22 and then adhering it to the outer peripheral surface of the housing part 1 of the inner container A. Can be given. Another example is a method of attaching the tongue piece 22 to the outer peripheral surface of the housing 1 with a double-sided adhesive tape.

The tongue piece 22 provided on the side wall of the outer container B is preferably provided on at least two side walls of the four side walls facing the housing portion 1 of the inner container A in terms of the fixing effect. The number of the tongue pieces 22 provided on one side wall may be one or plural, but usually one is sufficient.

[0043]

[Effect of device]

 In the ink container of the present invention, one side of the outer container is opened, so that the color and the remaining amount of the ink in the inner container can be confirmed from the outside. Further, since the side of the inner container having the mouthpiece is made of a rigid casing, and this casing is fixed to the outer container, it is easy to mount the ink container on the printing machine.
