Description

[Detailed description of the invention] a. Industrial application field The present invention relates to an ink container, and in particular, a novel method for efficiently sucking out all the ink directly filled into a bendable casing. Regarding improvements.

b. Conventional technology This type of ink container conventionally used is
There are various configurations, but representative configurations used by the applicant as a commercial product include the configurations shown in Figures 8 and 9. .

That is, what is indicated by the reference numeral 1 in FIGS. 8 and 9 is a box having a rectangular shape as a whole, and the box 1 is made of paper, resin, or the like and can be assembled freely.

Inside this box body 1, a deformable bag-shaped casing 2 made of polyethylene, for example, is built in to house ink.
An ink suction port 4 is integrally formed in an ink suction portion 3 formed at one end of the casing 2, and a spring 2a is built in the casing 2.

The suction port 4 extends outwardly through a guide hole (not shown) of the casing 1, and a cap 5 is screwed into the suction port 4.

The conventional ink container is constructed as described above, and its operation will be explained below.

First, as shown in FIG. 8, when the casing 2 fully filled with ink and the ink container housed in the box 1 are attached to a rotary copying machine (not shown) and printing is started, the suction pump ( (not shown) sucks out the ink in the casing 2, and eventually the ink in the casing 2 becomes empty.
As shown in FIG. 9, the casing 2 has a bent sheet shape, leaving the thickness of the spring 2a.

In the above condition, the ink container was disposed of.
Disposed of as garbage.

c. Problems to be solved by the invention Since the conventional ink container was constructed as described above, it had the following problems.

(1) Since the casing for containing the ink must be housed inside the box, it has a double structure, which increases the cost of the ink container.

(2) Even when the ink is empty, the shape of the casing itself becomes a sheet, but the shape of the box does not change at all, and even when disposed of as garbage, it occupies wasted space. It wasn't space efficient. Further, by providing a spring, the cost increases accordingly.

The present invention was made to solve the above-mentioned problems, and in particular, to provide an ink container that can efficiently suck out all of the ink directly filled in the bendable casing. The purpose is to

d. Means for Solving the Problems The ink container according to the present invention includes a bendable casing having a plurality of bending parts, and an ink suction port formed on one surface of the casing, and an ink container close to the ink suction port. The bending strength of the bent portion at a position is made stronger than the bending strength of the bent portion at a position far from the ink suction port.

e Effect In the ink container according to the present invention, the bending strength of the bent portion near the ink suction port is stronger than the bending strength of the bent portion located far from the ink suction port. When suctioning, the bent part located far from the ink suction port bends and deforms first, and then, as suction continues, the bent part located close to the ink suction port bends and deforms, causing ink to remain inside the casing. The ink suction operation is performed in an extremely favorable condition without causing any problems.

Therefore, ink can be completely sucked out without the phenomenon that the inside of the casing at a position close to the ink suction port deforms and collapses first, and the ink inside the casing at a position far from the ink suction port remains. .

Furthermore, since the casing is the only ink container used to store the ink, the space efficiency for disposing of the ink container after use is extremely good.

f. Embodiments Hereinafter, preferred embodiments of the ink container according to the present invention will be described in detail with reference to the drawings.

Figures 1 to 7 are for showing the ink container according to the present invention. Figure 1 is a front view, Figure 2 is a plan view of Figure 1, and Figure 3 shows a partially deformed state. 4 is a plan view of the state shown in FIG. 3, FIG. 5 is a front view showing an almost completely deformed state, FIG. 6 is a plan view of the state shown in FIG. 5, and FIG. 7 is a state shown in FIG. 4. FIG.

Note that the same or equivalent parts as in the conventional example will be described using the same reference numerals.

In the drawings, the reference numeral 2 indicates a casing made of, for example, a flexible resin material and having a box-like overall shape, and this casing 2 is shown in FIGS. 1 and 2. As such, an ink suction port 4 having a suction hole 4a is formed integrally or separately at the lower part of one surface 2a, and a cap 5 is removably attached to the ink suction port 4.

Bent portions 2b, 2c, 2d, and 2e are formed on each side, upper surface, and lower surface of the casing 2, as shown by dotted lines in FIGS. 1 and 2, and are located near the ink suction port 4. Bent part 2b of
and 2d are configured to have a stronger bending strength than the bent portions 2c and 2e located far from the ink suction port 4.

In other words, the bent portions 2b and 2d may be made thicker than the bent portions 2c and 2e, or may be coated with a material that is difficult to bend. It is configured to be more difficult to bend than the bending parts 2c and 2e, and during the ink suction operation, the empty part 7 located far from the ink suction port 4 is more comfortable than the empty part 6 located closer to the ink suction port 4. It is constructed so that it contracts first and becomes empty.

Further, the bent portions 2b and 2c formed on each side of the casing 2 are formed in a direction substantially parallel to one surface 2a of the casing 2.

The ink container according to the present invention is constructed as described above, and its operation will be explained below.

First, when the casing 2 is fully filled with ink, the ink container has a rectangular box shape as shown in FIG. After the ink suction port 4 with the cap 5 removed is attached to the suction pump (not shown), printing is started.

As the printing operation described above progresses, first, the bending parts 2c and 2e, which have weak bending strength, begin to bend, and the ink in the empty part 7 located far from the ink suction port 4 first decreases, and the casing 2 The shape of the first
The shape shown in the figure changes to the shape shown in FIGS. 3, 4, and 7.

Furthermore, when printing continues and the suction force from the ink suction port 4 exceeds the bending strength of each bending part 2b and 2d, each bending part 2b and 2d bends,
The ink in the empty part 6 also becomes empty, and the casing 2
is almost empty as shown in FIGS. 5 and 6.

Therefore, when ink is sucked out, the ink in the space 7 located far from the ink suction port 4 is emptied first, and the space 6 located close to the ink suction port 4 is emptied later. Therefore, no ink remains in a part of the casing 2.

Note that the shape and position of each of the bent portions 2b to 2e of the casing 2 are not limited to the above-mentioned embodiments, and other shapes and positions may be used.
The shape is not limited to a rectangular shape, and the same effects can be obtained even when the shape is, for example, another shape. Furthermore, the material of the casing 2 is not limited to the above-mentioned resin material, but may be made from flexible paper, processed paper, or a combination of two or three layers of paper and processed paper, and metal foil and resin film. The suction port can also be integrated with the casing or separate from it.
It can also be made of resin or metal.

g. Effects of the invention Since the ink container according to the invention is constructed as described above, various effects such as those described below can be obtained.

(1) Since the casing itself also serves as an ink container, the structure is extremely simple and significant cost reductions can be achieved.

(2) Since the bending strength of each bent part of the casing is different, the bending part farthest from the suction port can be bent first, and the bent part closest to the suction port can be bent later. It is possible to reliably prevent ink from remaining inside the casing.

(3) Also, when all the ink in the casing is used up,
When the inside is empty, the shape of the casing becomes extremely small, and when disposing of the ink container that is no longer needed, space efficiency becomes extremely good.
