CONSTITUTION:A container 1 is molded under a state in which notch parts 7-10 and opening parts 11-14 are formed on part of peripheral wall 3 and with the same kind of metal mold. All the parts 15-18 capable of being cut off remain when they are in a molded state. A pair of cutters 19, 19 are provided according to the color of ink among the parts 15-18 capable of being cut off on the ink filler side, and only by installing the container 1, a specific part capable of being cut off is cut off. A projection 20 is protoruded on the apparatus side corresponding to the cut off part of the container for which filling has been completed. Therefore, unless a specific projection 20 corresponds to a specific notch part being cut off, the container 1 can not throughly 50 mounted because one of the remainding parts 15-18 prevents the mounting.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container, and more particularly to a container configured so that different contents filled inside can be mechanically identified. be.

[Prior Art] For example, a color inkjet printer uses a plurality of types of containers called ink cartridges filled with ink of different colors.

These containers must be replaced when the ink runs out and are removably attached to the device.

Further, ink cartridges filled with ink of a specific color are installed in specific positions, and if the ink cartridges are installed in different positions, the inks will mix.

Therefore, the tip of the ink cartridge is provided with notches at different positions depending on the color of the ink, and a protrusion is provided corresponding to each notch on the device side, and unless the protrusion and the notch match, the ink cartridge was made completely impossible to install.

If such a structure is adopted, incorrect installation of the ink cartridge will not occur.

[Problems to be Solved by the Invention] However, when the above structure is employed, the following problems arise.

One of them is the mold problem.

That is, in order to mold containers in which notches are formed at different positions, it is necessary to prepare a number of containers corresponding to the types of containers, which increases the cost.

There is a method of molding in one mold using a core without using different molds, but this results in a complicated core and increases the cost as well as when using multiple molds.

Other problems involve storage and handling of the shaped containers.

In other words, since the containers have the same shape except for the position and shape of the notch, the operator may make a sorting mistake.

Yet another major problem is the incorrect filling of ink due to the above-mentioned selection error.

In other words, currently, ink filling work is carried out without automatic container sorting, so if the operator makes a mistake in sorting the containers, ink of a different color will be filled into the container and the printer will be sent directly to the printer. If it is attached to a printer, it can lead to serious accidents such as mixing of inks or recording with two or more types of ink of the same color.

[Means for Solving the Problems] In order to solve the above-mentioned problems, in the present invention, although the shapes are molded into exactly the same shape at the time of molding, a plurality of removable parts are provided in some parts. The established structure was adopted.

[For production]

By adopting the above-mentioned structure, it is possible to mold all the containers with one type of mold, reducing costs.In addition, it is possible to reduce the cost by molding all the containers with one type of mold. If you try to remove it.

The removed portion becomes a notch corresponding to a specific color, and human errors such as incorrect container selection can be completely prevented from occurring.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 and subsequent figures illustrate one embodiment of the present invention. In the figures, the container designated by the symbol l is exemplified as an ink cartridge, and is formed as an elongated, flat, hollow container.

A handle 2 that can be used for attachment and detachment is integrally provided at one end of the container 1 in the K1 direction, and a peripheral wall 3 is integrally provided at the other end to protrude over a predetermined angle.

Surrounded by this peripheral wall 3, a valve 4 for filling and discharging ink is provided.

On the other hand, a part of the second peripheral wall 3 is used to form a cutout portion as shown in FIG.

That is, a notch 5 is formed in the center of the peripheral wall 3 on either the upper or lower side of the container 1 .

This notch 5 is wide at the entrance end and becomes narrower toward the inside.
It also has a widening shape.

A container fixing protrusion 6 protruding from the apparatus side is fitted into this notch.

That is, the protrusion 6 has a substantially cylindrical shape, and its diameter is larger than the constricted part in the middle of the notch 5. When the protrusion 6 is injected into the notch 5, the container 1
Hold the container 1 so that it will not fall out unless a large force is applied to it.

In addition, two quadrilateral notches 7 to 10 are formed in the peripheral wall 3 in a symmetrical manner with the notch 5 in between,
Openings 11 to 14 are formed at positions closer to the inner side of the peripheral wall 3 in correspondence with these notches 7 to 10.

Then, the notches 7 to 1O and the opening 11 facing thereto
- 14, removable parts 15-18 are formed.

Next, a method of using the container according to the present invention constructed as described above will be explained.

The container 1 is molded using the same type of mold with cutouts 7 to 10 and openings 11 to 14 formed in part of the peripheral wall 3 as shown in FIG.

In the molded state, all of the removable parts 15-18 remain intact, as shown in FIG.

Therefore, all containers are exactly the same, and the operator does not have to make any effort to distinguish between them.

On the other hand, when filling ink, a container 1 is placed on the side of the ink filling device.
When mounted, a pair of cutters 19 and 19 are provided corresponding to any one of the removable parts 15 to 18 predetermined according to the color of the ink.

These cutters 19.19 have cutouts 7 as shown in FIG.
They are spaced apart by the same width as ~10.

Therefore, just by mounting the container 1 on the ink filling device side, the specific removable portion is cut off as shown in FIG.

At the same time as this cutting operation, ink is filled from an ink filling device (not shown) via a valve 4.

That is, a specific ablation corresponding to a specific ink color
The surgical resection and the filling of a specific color ink are performed at the same time, and there is no need to select a container.
A protrusion 20 is provided protruding from the device side.

This protrusion 20 is cut out as shown in FIG. 1 and I! 1!
It is provided opposite to one of the specific notches 7 to 10 which are continuous notches.

Therefore, unless a specific protrusion 20 and a specific excised notch correspond, the container l cannot be completely attached, and is blocked by any of the remaining resectable parts 15-18, and the attachment is not possible. Can not.

As described above, it is possible to obtain a container in which there is no occurrence of erroneous insertion, including the manufacturing process of the container, the ink filling process, and the handling on the user's side, and there is no possibility of -ff and erroneous use. .

FIGS. 4(A) to 4(D) show examples in which the present invention is applied to four-color ink cartridges.

Figures 4 (A) to (D) are, for example, yellow, yellow,
This is an example of forming notches corresponding to each color of magenta, cyan, and black.

In addition, in the above-mentioned embodiment, an example was shown in which the notch part or the removable part was formed only on one side of the peripheral wall of the container.
It may be formed on both the upper and lower surfaces, or on one or both of the left and right sides.

If they are provided on the top and bottom, left and right sides of the container, there is no need to select the direction when mounting the container, and there is no possibility of incorrect mounting.

In addition, when using multiple colors of ink, there is a difference in the required amount of cartridges depending on which ink is used a lot and the ink which is used in a small amount, but if a two-color structure is adopted, the amount of ink required for the cartridge is the same. Since it is sufficient to fill the ink using a container, there is no problem of surplus cartridges filled with ink of a specific color.

In addition, although the above-mentioned embodiment shows only an example adapted to an ink cartridge, the substance that can be filled in the container is not limited to ink, but can also contain multiple different types of contents such as other liquids and powders. can be adapted to all.

"Effects" As is clear from the description below, according to the present invention, a plurality of removable parts are provided using one end of the peripheral wall of the container,
Since we have adopted a structure in which a specific removable part is cut out according to the contents when filling the contents, it is possible to obtain multiple types of containers according to different contents with one type of mold, which greatly reduces the cost. Cost reductions can be achieved, incorrect filling of contents will not occur, and process control will be extremely easy.
