[0001] INK SUPPLY CONTAINER FOR PRINTER [0002]

More particularly, the present invention relates to a printer ink supply container, and more particularly, it can be used while replenishing ink. In addition, since the easy shrinkage of ink is consumed, an air inlet is not required, The present invention relates to an ink supply container for a printer, which can prevent air from flowing into a printer.

A printer is a device that prints a character or a picture while ejecting ink from the head, and is a device now commonly used in personal computers today. Today, color printers are commonly used to express various colors while mixing inks of various colors. The ink container used in the printer is called a cartridge, which is a precision part because it must not only supply ink of uniform pressure continuously to the printer but also should not introduce air. Thus, cartridges have been sold at a high price by making dedicated cartridges for each manufacturer of the printer. Therefore, replacing the cartridges a few times puts a heavy burden on the consumer, which is more expensive than the printer.

In order to solve such a problem, an ink container which can be used while supplementing ink and which can be used regardless of the manufacturer of the printer has been manufactured and used. Such an ink container was called an infinite refill ink container.

An infinite refill ink container is an ink container which is provided with an ink container on the outside of a printer and connects the ink container with the head of the printer by an ink supply pipe to supply ink from the outside, .

As an infinite refill ink container according to the prior art, Korean Patent Publication No. 10-2005-0051614 and Korean Utility Model No. 20-2013-0005158 are disclosed. These prior arts are similar in that there is a container made of plastic outside and a method of using the container in connection with the nozzle of the printer.

The infinite refill ink container having the above-described structure is provided with a separate air hole through which air can flow into the ink container to solve the problem that the ink is not supplied smoothly because the inside is evacuated as the ink is exhausted. Therefore, the space which is empty when the ink is exhausted is entrained by the inflow of air from the outside. However, if air continues to flow into the interior of the ink container as described above, there is a problem in that air is introduced through the ink supply pipe when the ink is exhausted. When air is introduced into the nozzles through the ink supply pipe, the ink is mixed with the nozzles, so that normal printing can not be performed. In addition, mixed ink flows back into the ink containers of different colors. In order to avoid this problem, the user of the printer should always pay attention to how much ink is left and replenish ink as soon as the ink is exhausted to some extent. In addition, when air holes are formed in the ink container, the ink may flow into the air holes in the course of charging the ink or transferring the printer, thereby causing contamination of the surroundings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing a state in which an ink supply container for a printer according to the present invention is installed on a cradle, FIG. 2 is a view showing a configuration of an ink supply container for a printer according to the present invention, And the container is in a contracted state.

1 and 2, an ink supply container 100 for a printer according to the present invention includes a container body 110, a lid 150 detachably coupled to the spout 130 of the container body 110, And an ink supply pipe 170 connecting the ink supply container 100 and the nozzle.

The container body 110 may be configured in various shapes as long as it is capable of storing ink. However, in a preferred embodiment of the present invention, the container body 110 is configured as a hexahedron as shown in the figure. This is because, as will be described later, the ink supply container 100 according to the present invention preferably uses a plurality of ink droplets stored in various colors arranged side-by-side, so that the contact surface is flat. However, it should be understood that the above-described shape represents a preferred example of the present invention, and it is a matter of course that the ink supply container 100 may have various known shapes as long as the ink supply containers 100 are arranged in parallel. The container body 110 is made of a flexible material that is easily bent or folded, and is preferably made of a synthetic material container containing PVC and urethane resin.

In another embodiment of the present invention, the container body 110 may be configured to have a lower surface (directional display with reference to FIG. 2, hereinafter the same) . Thus, when the content of the container body 110 is reduced, the container body 110 can be contracted in the vertical direction. The purpose of causing the container body 110 to contract as the content of the container body 110 is reduced will be described later.

A spout 130 is provided at an upper portion of the container body 110. The spout 130 is configured to protrude upward from the container body 110 and is made of a material thicker or harder than the container body 110 described above so that the shape of the spout 130 Do not change the structure. The lid 150 is detachably coupled to the spout 130. Thus, ink is injected through the spout 130, and then the ink is sealed by the cap 150.

On the other hand, a fixing hook portion 135 may be further provided on the side surface of the spout 130. As shown in FIG. 3, in the container body 110 according to the present invention, the ink container is shrunk as the liquid ink filled therein is exhausted. Therefore, as the ink gets deeper, the container body 110 may collapse or shrink and lose its original shape or condition, so that the container body 110 may be tilted or tilted when the container body 110 is left untouched. Therefore, it is necessary to fix the spout 130 of the ink container to the cradle 190 so as to float lightly in the air to maintain a stable posture even if the ink container shrinks (see FIGS. 1 and 5). The fixing hook portion 135 may be formed with a horizontal groove 131 on the side surface of the spout 130. So that the plate-like structure can be slidably engaged with the horizontal groove 131 of the fixing hook 135. It is needless to say that a variety of known structures can be applied as long as the spout 130 is mounted on the cradle 190 and the container body 110 can be coupled to the cradle 190 in a hanging manner.

4 is a cross-sectional view of an ink supply container provided with an ink supply tube according to the present invention.

The ink supply pipe 170 according to the present invention serves as a passage for supplying the liquid ink stored in the container body 110 to the nozzle of the printer (not shown), and a translucent tube made of a flexible material can be used. The ink supply pipe 170 is a well-known technique commonly used in the conventional infinite refill ink container, and a detailed description thereof will be omitted.

The ink supply pipe 170 is connected to the container body 110 through any part of the container body 110 except for the side surface and the lower surface which are the shrinking portions of the container body 110 and is configured to extend to the inner lower portion of the container body 110. The ink supply pipe 170 may be configured to pass through the side of the spout 130 of the ink supply container 100 as shown in the figure. In the preferred embodiment of the present invention, the end of the ink supply pipe 170 is configured not to be flat. When the end of the ink supply pipe 170 is flat, the ink supply pipe 170 may be clogged by the wall surface of the container body 110 during the contraction of the container body 110. Therefore, the end of the ink supply pipe 170 should be able to receive ink even if it faces the container body 110 or is in close contact with it. In a preferred embodiment of the present invention, the end of the ink supply pipe 170 may be configured so that at least one side of the side is cut in the longitudinal direction (see FIG. 4). That is, a V-shaped cut-out portion 175 may be provided on the side of the end of the ink supply pipe 170, or a separate hole (not shown) may be formed on the side of the end.

5 is a view showing a state in which the ink supply container according to the present invention is mounted on a cradle.

Referring to FIGS. 1 and 5, the holder 190 may have a hollow tube shape or box shape having a rectangular cross section. The upper plate 193 of the holder 190 is configured to be detachable and openable. A container mounting portion 195 having one side opened is formed in the upper plate 193. The container mounting portion 195 has a width and a thickness corresponding to the horizontal grooves 131 of the fixing hook 135 described above. When the horizontal groove 131 is aligned with the container mounting portion 195 and inserted through the opening portion, the container mounting portion 195 is inserted into the horizontal groove 131 and is engaged while sliding. The height of the holder 190 may be a size corresponding to the height from the bottom surface of the ink supply container 100 to the horizontal groove 131. When the ink supply container 100 is mounted on the mounting table 190 in a state where the container main body 110 is fully charged with ink, the bottom surface of the container main body 110 lightly touches the inside of the bottom surface of the mounting table 190, They are combined in a floating state. When the ink is exhausted in the above state, the ink supply container 100 is held in a stable state on the mount table 190, and only the container main body 110 is contracted upward.

Meanwhile, since the holder 190 is mounted with a plurality of ink supply vessels 100 of various colors, it needs to be formed in a shape extending to a predetermined length (see FIG. 1).

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
