[First Embodiment]
(Constitution)
1 to 4 show a first embodiment. FIG. 1 is a side view illustrating a schematic configuration of a printing ink tube container 1 in which printing ink is accommodated. The tube container 1 has a tube body 2 which is a laminated tube, for example. The tube body 2 is formed by laminating at least a polyolefin resin layer such as polyethylene, an adhesive resin layer, and an oxygen barrier layer, and a coating layer excellent in resistance to the components contained in the printing ink is disposed on the inner peripheral surface. Molded so that the peripheral wall is deformable.

  Here, the oxygen barrier layer is, for example, a resin obtained by depositing aluminum or silicon oxide on a resin film substrate such as polyolefin or PET, a reaction product of aluminum oxide and a phosphoric acid compound, or a conjugated diene compound. Those coated on a film substrate, and further aluminum foil and the like.

  Moreover, the material excellent in tolerance with respect to various printing inks, such as polyvinyl alcohol, a PET film, and aluminum foil, can be used suitably for the coating layer excellent in the tolerance with respect to the contained component of printing ink.

  A closed end 3 is formed at one end of the tube body 2 and an ink outlet 4 is formed at the other end. For example, the closed end 3 is obtained by firmly fixing an overlapping portion obtained by folding and overlapping one end portion of a laminate tube by means of thermocompression bonding or adhesion. For example, the closed end 3 may also be configured to serve as a tube throttling device.

  The ink outlet 4 connects the base 4a having the same diameter as the diameter of the laminated tube, the cylindrical nozzle 4b having a diameter smaller than that of the base 4a, and the base 4a and the nozzle 4b. And a tapered connecting portion 4c. The ink outlet 4 may be integrally formed with a hard resin material, for example. You may make it the structure which joins the opening edge part of the laminate tube of the tube main body 2 to this ink outlet part 4 by means, such as adhesion | attachment. Furthermore, for example, a male screw portion 4d is formed on the peripheral wall portion of the nozzle portion 4b. A female screw portion 5a of a cap portion 5 (see FIG. 7) that closes the ink outlet portion 4 of the tube main body 2 so as to be openable and closable is screwed to the male screw portion 4d of the nozzle portion 4b.

  Moreover, the tube container 1 of this Embodiment is set and used for the substantially L-shaped holder (support stand) 6 as shown in FIG.2 and FIG.3. The holder 6 includes a guide plate 7, support leg portions 8, and a fixing member 9. The guide plate 7 is a flat plate arranged in the horizontal plane direction. The support leg portion 8 extends in the vertical direction while being bent from one end of the guide plate 7. The fixing member 9 is formed by, for example, two fixing bands 10 that are arranged apart from each other in the vertical direction.

  On the back surface of the support leg 8 (the surface opposite to the contact surface with the tube container 1), a pair of left and right engaging projections 11a and 11b are formed at positions corresponding to the upper and lower fixing bands 10, respectively. . One locking projection 11a is fixed in a state where one end 10a of the fixing band 10 is locked. The fixed band 10 is fixed in a state in which the other end 10b is detachably locked to the other locking projection 11b of the support leg 8 while being wound around the tube body 2. When the tube container 1 is set in the holder 6, as shown in FIG. 2, the tube main body 2 has the ink outlet portion 4 disposed downward and the tube main body 2 disposed along the support leg portion 8. The two fixing bands 10 are fixed in the state.

  Further, as shown in FIG. 4, the nozzle part 4b of the ink outlet part 4 is formed with a blocking film part 4e that closes the inside of the nozzle opening. An X-shaped cut portion 4f is formed in the blocking film portion 4e. For example, when the tube container 1 is not used, the cut portion 4f is held in an unbroken state. When the tube container 1 is used, the tube container 1 is broken by an unillustrated X-shaped pushing member incorporated in the cap portion 5 or the holder 6, for example. In this state, the ink inside the tube container 1 can flow out to the outside through the gap between the cut portions 4f. Further, the cut portion 4f is elastically deformed in a direction to widen the gap between the cut portions 4f when a pressing force is applied from the ink side inside the tube container 1, and allows the ink to flow out from the tube body 2. . When no pressing force is applied from the ink side inside the tube container 1, the blocking film portion 4e elastically returns in the direction of narrowing the gap between the cut portions 4f having the original shape. Thereby, it functions as a check valve that prevents the inflow of air from the ink outlet portion 4 to the inside of the tube body 2.

(Action / Effect)
In the tube container 1 for printing ink of this Embodiment, since ink is filled in the tube container 1, since air does not enter in the tube container 1, drying and oxidation of ink can be prevented. Furthermore, since the size of the opening of the nozzle portion 4b of the ink outlet portion 4 of the tube body 2 is constant, the amount of ink dispensed is constant. Therefore, as shown in FIG. 1, the ink amount can be easily grasped by measuring the length of the ink amount flowing out from the ink outlet portion 4 of the tube main body 2 with the scale gauge 12. There is an effect.

  If the viscosity of the printing ink is low, the printing ink along the cut shape may not come out from the cut portion. In such a case, it is necessary to increase the viscosity of the printing ink in advance by adding a thickener or increasing the amount of the binder.

  Further, when the tube container 1 of the present embodiment is set in the holder 6 and used, the guide plate 7 is, for example, in a state in which the guide plate 7 is applied to the bed 13 which is an ink receiver as shown in FIG. 13 along a straight line. At this time, the length of the ink amount to be squeezed onto the sled base 13 can be easily measured by narrowing the tube container 1 with a constant force. Therefore, in this case as well, since the ink amount can be easily grasped, there is an effect that the ink adjustment is simplified.

  Further, in the tube container 1 of the present embodiment, the blocking film portion 4e is formed in the nozzle portion 4b of the ink outlet portion 4, and this X-shaped cut portion 4f functions as a check valve. Therefore, even if the pushing of the tube container 1 is interrupted during the ink squeezing operation of the tube container 1, the inflow of air from the ink outlet portion 4 to the inside of the tube body 2 can be prevented. As a result, since air does not enter the tube container 1, the drying and oxidation of the ink can be prevented.

On the inner peripheral surface of the cap portion 24, a ring-shaped engagement groove portion 26 having a shape corresponding to the engagement convex portion 25 is formed. The cap 24 is engaged with the engaging groove 25 so that the engaging protrusion 25 can be engaged and disengaged when the cap 24 is fitted to the outer peripheral surface of the base 4 a of the base 4 a of the ink outlet 4. It has become.

  Further, a linear blocking portion 27 that closes the opening of the mouth 23 of the ink outlet portion 4 is provided at the bottom of the cap portion 24. When the cap portion 24 is connected to the ink outlet portion 4 of the tube body 2, the closing portion 27 closes the outflow port 22 of the mouth body 23 of the ink outlet portion 4. The inflow of air to the inside of the tube body 2 is prevented.

(Action / Effect)
According to the printing ink tube container 21 of the present embodiment, when the cap portion 24 is connected to the ink outlet portion 4 of the tube body 2, the closing portion 27 of the cap portion 24 is the mouth 23 of the ink outlet portion 4. By closing the outlet 22, the inflow of air from the ink outlet 4 to the inside of the tube body 2 is prevented. Therefore, drying and oxidation of ink can be prevented also in this embodiment.

  Further, in the present embodiment, since the linearly formed outlet 22 is provided in the nozzle part 4b of the ink outlet part 4, the length of the amount of ink flowing out from the nozzle part 4b of the ink outlet part 4 is accurately determined. Can be measured. Therefore, in the present embodiment, in addition to the effects of the first embodiment, it is easier to grasp the ink amount, so that there is an effect that the ink adjustment is further simplified.

[Third Embodiment]
FIG. 7 shows a third embodiment of the present invention. The present embodiment is a modification of the printing ink tube container 1 of the first embodiment (see FIGS. 1 to 4). In the present embodiment, a scale portion 31 is provided on the outer peripheral surface of the tube body 2 to indicate the amount of ink that flows out from the ink outlet portion 4. This scale part 31 can grasp | ascertain as a rough standard of the outflow amount of an ink by displaying the length of narrowing of the tube main body 2, for example. The scale part 31 may be configured to display the weight of the outflow amount of ink.

[Fourth Embodiment]
FIGS. 8A, 8B, and 9 show a fourth embodiment. The present embodiment is a modification of the ink outlet portion 4 of the printing ink tube container 1 of the first embodiment (see FIGS. 1 to 4). In the present embodiment, a check valve mechanism 41 is incorporated in the ink outlet portion 4. The check valve mechanism 41 has a substantially funnel-shaped valve body 42. As shown in FIG. 9, the valve body 42 includes a conical valve body 42a, a rod-like abutting portion 42b projecting on the apex side of the valve body 42a, and outwardly toward the opening end side of the valve body 42a. And a bent ring-shaped flange portion 42c. A plurality of holes 42d are formed in the peripheral wall portion of the valve body 42a.

  The ink outlet portion 4 is formed with a valve chamber 43 that accommodates the valve body 42 movably in the central axis direction of the tube body 2 inside the connecting portion 4c. A spring seat portion 43 a having a smaller diameter than the flange portion 42 c of the valve body 42 is formed at the base end portion of the valve chamber 43. An abutting surface 43b of a conical recess corresponding to the valve main body 42a is formed at the distal end portion of the valve chamber 43. Further, a compression coil spring 44 that urges the valve body 42 to press against the abutting surface 43b of the valve chamber 43 between the spring seat portion 43a of the valve chamber 43 and the flange portion 42c of the valve body 42. It is installed. Instead of the compression coil spring 44, an elastic body such as rubber may be used.

  The check valve mechanism 41 is normally held in a state in which the valve element 42 is in contact with the abutting surface 43b side of the valve chamber 43 as shown in FIG. 8A by the spring force of the compression coil spring 44. The In this state, the hole 42 d of the valve body 42 is held in a state of being closed by the abutting surface 43 b of the valve chamber 43. At this time, the inflow of air from the ink outlet portion 4 to the inside of the tube body 2 is prevented.

  8B, when the ink outlet 4 of the printing ink tube container 1 is pressed against the sled base 13 or the like, the abutting portion 42b of the valve element 42 is the spring of the compression coil spring 44. It is pushed into the valve chamber 43 against the force. In this case, the valve body 42 a of the valve body 42 is moved in a direction away from the abutting surface 43 b of the valve chamber 43. Therefore, the ink inside the tube body 2 flows out through the hole 42d of the valve body 42.

(Action / Effect)
In the printing ink tube container 1 of the present embodiment, as shown in FIG. 8 (B), the ink outlet portion 4 of the printing ink tube container 1 is pressed against the sled base 13 or the like. Squeezing work is performed. Further, when the ink outlet 4 of the printing ink tube container 1 is separated from the sled base 13 or the like, the valve element 42 is pushed into the valve chamber 43 by the spring force of the compression coil spring 44 as shown in FIG. It is moved to a state where it abuts on the abutting surface 43b side. In this state, the hole 42 d of the valve body 42 is held in a state of being closed by the abutting surface 43 b of the valve chamber 43. Therefore, when the pushing of the tube container 1 is interrupted during the ink squeezing operation of the tube container 1, the inflow of air from the ink outlet portion 4 to the inside of the tube body 2 can be prevented. As a result, since air does not enter the tube container 1, the drying and oxidation of the ink can be prevented.

  Therefore, even the printing ink tube container 1 of the present embodiment can provide a printing ink tube container that can prevent the ink from being dried and oxidized and can be easily adjusted for the ink to be dispensed.

  The present invention is not limited to the above embodiment. For example, the tube body 2 of the tube container 1 may be formed by a double tube including an outer tube made of hard resin and an inner tube that is more flexible than the outer tube. Here, when the ink flows out, air is caused to flow between the outer tube and the inner tube when the inner tube is crushed, so that the inner tube is restored to its original shape by the air pressure between the outer tube and the inner tube. Prevent return. Thereby, you may make it the structure which prevents drying and oxidation of an ink so that air may not enter into the tube container 1. FIG. Furthermore, it goes without saying that various modifications can be made without departing from the scope of the present invention.
