Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to a cartridge tube containing a fluid such as ink inside.

(Prior Art) Conventionally, a cartridge tube composed of a container body having a hard opening at an upper end opening is known. A fluid such as printing ink is stored inside the container body, and the printing ink or the like inside is sucked by a suction pump,
The sucked ink is sent to a printing machine and used for a printing operation.

However, aluminum tubes and blow tubes are generally used for the container body, but as these suction tubes progress, the container body cannot withstand the decompression by the suction pump, and the inner wall surfaces of the container body have a hard mouth. It may be in close contact. In addition, when a laminated tube is used in terms of storage stability and strength, the phenomenon occurs more remarkably because the material is soft. As a result, it is difficult to suck ink because the ink flow path is not secured,
There is a problem that a considerable amount of ink remains in the container body.

As a solution, Japanese Utility Model Application Laid-Open No. 59-76347,
It is proposed to provide a guide rod for securing an ink flow path inside a tube, as seen in -76348.

(Problem to be Solved by the Invention) In the configuration described in Japanese Utility Model Application Laid-Open No. 59-76347, the guide rod is arranged and fixed at the eccentric position inside the head flange of the tube. An ink flow path is intended to be secured between the inner surface of the tube container main body and the guide rod by inhibiting the suction adhesion of the container main body due to the presence of the guide rod.

However, in such a configuration, since the arrangement position of the guide rod is eccentric with respect to the head flange, the formation of the ink flow path by the guide rod is not necessarily directly connected to the opening of the tube container. However, a problem that the ink flow path is not formed sometimes occurs. This tendency is particularly strong when the head flange is soft. Therefore, the problem that the remaining amount of ink remains in the tube container body has not been solved.

In the configuration described in Japanese Utility Model Application Laid-Open No. 59-76348, the guide rod having a pair of locking ends having an interval or width larger than the inner diameter of the outlet of the head flange is provided inside the tube container body. The interior is to be installed.

However, in such a configuration, since the guide rod is not fixed to the tube container main body, the operator moves the inside of the tube container body by careless handling to form the ink flow path by the guide rod. There is a problem that it is not connected to the opening.

The present invention has been developed in consideration of the above-described problems, and has as its object to provide a cartridge tube capable of reliably reducing the remaining amount of ink.

[Structure of device]

(Means for Solving the Problems) The present invention is a cartridge tube provided with a hard mouth at an upper end opening of a laminated container main body, wherein an annular shoulder is provided at an upper end of the container main body, and this annular shoulder is provided. Along with bonding and fixing the annular plate provided at the lower portion of the hard mouth, a pair of engaging pieces extending downward from the hard mouth through the opening are provided, and a frame having a pair of mounting pieces is provided on the engaging piece. The cartridge tube is mounted and fixed via the mounting piece, and the frame body extends into the container main body, and is configured such that a fluid flow path is formed therein.

Making the cross section of the frame body substantially H-shaped greatly contributes to solving the problem.

(Operation) According to the present invention, a pair of engagement pieces extending downward from the hard opening through the upper end opening of the container are provided, and the frame extending into the container body is attached and fixed to the engagement pieces. Since the body can be firmly fixed by the engagement piece and the frame is disposed on a virtual extension line of the opening, the fluid flow path formed inside the frame and the opening are easily connected directly.

(Example) Hereinafter, an example of the present invention is described with reference to drawings.

1 to 5 show a first embodiment of a cartridge tube according to the present invention. FIG. 1 is a partial sectional side view of a cartridge tube.
And a hard opening 13 provided at an upper end opening of the container body 11. That is, an annular shoulder 12 is provided at the upper end of the container body 11,
An annular plate 14 provided below the hard opening 13 is adhesively fixed to the annular shoulder 12.

Further, a male screw portion 15 for mounting a cap (not shown) is formed substantially at the outer periphery of the center of the hard mouth portion 13, and a pair of engagement pieces 16 extending downward from the hard mouth portion 13 through the opening are provided. Each of them is provided with a locking recess 16a.

At the lower part of the hard opening 13, a frame 17 extending substantially over the entire area in the longitudinal direction in the container body 11 is attached. This frame 17
It is composed of a pair of side plates 21 and a connecting plate 22 arranged between the pair of side plates 21 at right angles. At the upper ends of the pair of side plates 21,
A pair of mounting pieces 18 to be mounted on a pair of engaging pieces 16 of the hard mouth portion 13
Each of the mounting pieces 18 is provided with a locking projection 18a that fits into the locking recess 16a of the pair of engaging pieces 16.

Further, the connecting plate 22 extends further downward from the pair of side plates 21, and the lower end 22a of the connecting plate 22 has an inverted triangular shape.

As shown in FIGS. 2 and 5, the frame 17 has a substantially H-shaped cross section, except for a pair of upper mounting pieces 18 and a lower end 22a of the lower connecting plate. Thereby, the ink flow path 20 is secured inside the frame 17.

The material of the container body 11 made of laminate used in this embodiment is not particularly limited, but has the following layer configuration.

 HDPE / PET / Al / HDPE or PP / PET / Al / PP where HDPE: Heiden polyethylene PET: Polyester Al: Aluminum PP: Polypropylene.

The hard opening 13 is generally formed of a polyolefin-based molded product. The frame 17 is made of polyethylene or polypropylene.

Next, the operation of the present embodiment having such a configuration will be described.

To assemble the cartridge tube 10, first, the pair of mounting pieces 1 are inserted into the locking recesses 16 a of the pair of engaging pieces 16 of the hard mouth 13.
By fitting the locking projection 18a of the frame 8, the frame 17 is
Securely locked to 13.

After attaching the frame 17 to the lower part of the hard mouth 13 in this way,
The annular plate 14 of the hard opening 13 is bonded and fixed to the annular shoulder 12 of the container body 11. Thus, the cartridge tube 10 is obtained. Normally, ink is stored in the container body 11 of the cartridge tube 10.

To use the cartridge tube 10, first remove the cap from the male screw portion 15 of the hard mouth portion 13, then attach a suction pump (not shown) to the hard mouth portion 13 and store it in the container body 11. The sucked ink is sucked by the suction pump. As the suction operation proceeds, the inside of the soft laminate container body 11 is depressurized by the suction pump, and the inner wall surfaces of the container body 11 approach each other as shown in FIG. in this case,
Since the frame 17 is provided in the container body 11, this frame
An ink flow path 20 is formed inside 17, and the ink is guided to the suction pump via the ink flow path 20.

According to the present embodiment, since the ink flow path 20 is formed inside the frame 17, even when the suction operation proceeds, the inner walls of the container body 11 do not adhere to each other. Therefore, the remaining amount of ink in the container body 11 can be reliably reduced.

Next, a second embodiment of the present invention will be described with reference to FIGS. 6 and 7. FIG. The second embodiment is the same as the first embodiment except that the structure of the frame is different from the first embodiment.

Thus, as shown in FIGS. 6 and 7, the frame 25
Is composed of a pair of side plates 26 and a connecting plate 27 arranged orthogonally between the pair of side plates 26. The pair of side plates 26 are connected in a tapered shape at one end (lower end), and the lower end 27a of the connection plate 27 is correspondingly formed as an inverted triangle.

The hard mouth 13 is provided at the other end (upper end) of the pair of side plates 26.
A pair of mounting pieces 28 to be mounted on the pair of engaging pieces 16 are provided, and each mounting piece 28 is provided with a locking projection 28a that is fitted into the locking recess 16a of the pair of engaging pieces 16.

In each of the above embodiments, an example in which the cross section of the frame 17 is substantially H-shaped is shown. However, the present invention is not limited to this, and the cross section may be U-shaped if a flow path is formed in the frame. May be in the shape of a square.

[Effect of the invention]

As described above, according to the present invention, a pair of engagement pieces extending downward from the hard mouth through the upper end opening of the container are provided, and the frame extending into the container body is attached and fixed to the engagement pieces.
The frame can be firmly fixed to the hard opening. Therefore, the frame does not fluctuate in the container body during use.

And since the hard mouth part provided with the engagement piece and the frame can be manufactured and formed separately, a complicated mold and the like for that purpose are not required, and the manufacturing cost can be reduced. Furthermore, since the frame is disposed on a virtual extension line of the opening, the fluid flow path formed inside the frame and the opening are easily connected directly, and the fluid in the frame is guided stably and reliably to the hard mouth side. It has a remarkable effect of gaining.
