Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a viscous liquid suction container for containing a viscous liquid such as ink of an ink self-priming type copying machine.

<Prior Art> The applicant of the present invention has joined one end of a flexible sheet cylinder of plastic to a peripheral portion of a square front plate having a lid-shaped suction port protruding from a lower edge of an outer surface in a direction opposite to the suction port. In Japanese Utility Model Application Laid-Open No. 64-17926, a viscous liquid suction container in which the viscous liquid is contained in the sheet cylinder and the other end is closed is proposed.

This container is housed in a prefabricated outer box with the suction port protruding outward from the front of the outer box, and the orientation of the suction port protruding outward is horizontal, and the ink suction port of the ink self-priming transcription printer. The ink inside the container is sucked out to the printing machine by the negative pressure acting on the ink suction port.

<Problems to be solved by the device> As the ink is sucked into the printing machine and the amount of ink in the container decreases, the upper wall of the flexible sheet cylinder is sucked by the negative pressure acting from the ink suction port into the container. When the amount of ink remaining in the container is reduced, the ink sticks to the inner surface of the front plate from top to bottom, and finally closes the small diameter hole opened in the front plate so as to communicate with the suction port. Then, the suction of the ink to the printing machine stops, so remove this container from the ink suction port of the printing machine and replace the new container. But,
When there is still about 10% ink in the removed container,
As much as 30% is left, and eventually this remaining ink is wasted.

<Means for Solving the Problems> The present invention is designed so that one end of a flexible sheet cylinder made of plastic is defined as a suction port at the peripheral portion of a plastic front plate with a lid-shaped suction port protruding from the lower edge of the outer surface. In a viscous liquid suction container that is joined in the opposite direction and contains viscous liquid in this sheet cylinder and closes the other end and stores it in an outer box, a horizontal baffle plate is attached to the inner surface of the front plate that stands almost vertically. An auxiliary member that projects integrally inward in the middle of the height and that faces the baffle plate from below from the lower side of the small diameter hole opened in the front plate so as to communicate with the suction port. It is characterized in that the baffle plate is integrally projected inward.

<Embodiment> In the illustrated embodiment, A is a container, and B is an outer box of an assembled paper container that encloses the container.

Container A is a rigid square front plate 1 made of plastic
And a flexible plastic thin sheet cylinder 3 of which one end is joined to a cylindrical frame portion 2 which integrally extends from the peripheral portion of the front plate, and the ink 4 is filled into the sheet cylinder 3 from the other end. Then, the other end of the sheet cylinder is closed. Bonding of one end of the sheet cylinder 3 to the front plate and closing of the other end are performed by heat sealing.

The front plate 1 is provided with an integral suction port 5 projecting in the opposite direction from the cylindrical frame part 2 and a small diameter hole 6 communicating with the inside of the suction port 5 at the outer surface of the lower edge portion, in this example, one corner portion. ing. Therefore, by connecting the suction port 5 to the ink suction port of the ink self-adsorption type copying machine, the ink 4 in the container is sucked to the printing machine through the small diameter hole 6.

Until the suction port is connected to the suction port of the printing machine, it is closed with the screw lid 7 to prevent ink from leaking from the suction port.
A rubber packing cylinder (not shown) may be attached to the inside of the suction port 5 in which a collar that comes into contact with the ink suction port of the printing machine is projected outside the suction port.

The outer box B is the same regular hexahedron as described in the above-mentioned conventional example, and the suction port 5 projects outward from the outer box.

According to the present invention, a baffle plate 8 and an auxiliary baffle plate 9 project inwardly on the inner surface of the front plate surrounded by the tubular frame portion 2.

The baffle plate 8 is horizontally provided in the middle of the height of the inner surface of the front plate, and its width is slightly smaller than the width of the front plate.

The auxiliary baffle plate 9 is provided at the lower edge of the opening of the small diameter hole 6 opened on the inner surface of the front plate, and faces the baffle plate 8 from below with the opening of the small diameter hole 6 interposed therebetween. In addition, in this embodiment, the auxiliary baffle plate 9 has a trough-shaped cross section that surrounds the lower half of the opening of the small diameter hole 6. The baffle plate 8 and the auxiliary baffle plate 9 may have the same inward length, but in this embodiment, the auxiliary baffle plate 9 is shorter than the baffle plate 8.

Since the front plate 1 is provided with the above-mentioned inward baffle plate 8 and auxiliary baffle plate 9 on the inner surface, the suction port 6 is connected to the ink suction port of the printing machine to apply the negative pressure to the ink in the printing machine to the printing machine. Supply,
When the amount of ink is reduced to about half, the upper half 3a (broken line in FIG. 3) of the sheet cylinder when the ink is full is sucked down by the negative pressure acting inside the container and droops down. However, it is prevented by the baffle plate 8 from sticking to the lower half part of the lower front plate from the baffle plate.

When the ink supply further continues and the amount of ink in the container becomes small, the lower half 3b of the sheet cylinder sticks to the lower half of the inner surface of the front plate from below as shown in FIG. The auxiliary baffle 9 prevents the auxiliary baffle 9 from sticking to the upper inner surface.

As a result, as shown in FIG. 5, the space held by the baffle plate 8 and the auxiliary baffle plate 9 remains in the container to the end, so that the entire amount of ink can be supplied to the printing machine without waste.

When the auxiliary baffle plate 9 is placed in a trough-shaped cross section that surrounds the lower half of the opening of the small-diameter hole as in this embodiment, the lower half part 3b of the seat tube 3 has the baffle plate 8 as shown in FIG. It is more preferable because it forms a funnel shape that connects each side edge of the auxiliary baffle plate 9 to each side edge of the auxiliary baffle plate 9, collects the ink in the trough-shaped auxiliary baffle plate 9 and causes the ink to flow into the small diameter hole 6.

<Effect of the device> To suck out the liquid in the bag to the end, attach a pipe to the small diameter hole of the front plate and make it penetrate into the bag, and form holes, slits, etc. on the peripheral surface of the pipe that has entered the bag. However, it is also necessary to process holes and slits in the pipe, and it is also necessary to insert the end of the pipe into the small diameter hole of the front plate and fix it by gluing. Costly.

On the other hand, in the present invention, when the front plate is molded, the viscous liquid in the container can be completely sucked out at a negative pressure without waste by simply providing the baffle plate and the auxiliary baffle plate integrally. There is no such trouble as in the case, and the productivity of the container is extremely high.
