Abstract
A liquid pack, a manufacturing method thereof, and an ink cartridge and a printer having the same are disclosed. The liquid pack according to the exemplary embodiment includes a liquid pack main body which is provided with a liquid therein and sealed, a liquid discharging portion which is provided in the liquid pack main body and through which the liquid is discharged to the outside, And a liquid injecting part which is spaced apart and is used to inject liquid into the liquid pack main body and take out the air in the liquid pack main body and to seal the inside of the liquid pack main body.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid supply technique, and more particularly, to a liquid pack, a manufacturing method thereof, and an ink cartridge and a printer having the same.
Generally, a printer receives ink from an ink cartridge mounted on the printer and performs printing. The ink cartridge may include a case and an ink pack housed in the case. The ink pack is filled with liquid ink according to the capacity of the ink pack. After the ink pack is filled with ink, the air existing in the ink pack is taken out.
Conventionally, a method of injecting ink through an ink discharging portion provided at the front end of the ink pack, closing the ink discharging portion with a stopper, and then injecting the injection needle into a cap to remove air inside the ink pack has been used. In this case, a fine passage due to the injection needle remains in the cap inside the ink discharge portion, and there is a problem that ink leaks through the fine passage.
On the other hand, there is a problem in that when the air present in the ink pack is taken out, the air present in the ink pack can not be completely removed. That is, ink is not present only in the ink pack, but a certain amount of air (air bubbles) remains. When air remains in the ink pack, residual air is output together with the ink when the ink is output from the ink pack, thereby damaging the print head or deteriorating the print quality.
Korean Unexamined Patent Application Publication No. 10-2006-0119272 (November 24, 2006)
An embodiment of the present invention is to provide a liquid pack capable of preventing ink from leaking out of the liquid pack, a manufacturing method thereof, and an ink cartridge and a printer having the same.
An embodiment of the present invention is to provide a liquid pack which can prevent gas from being discharged from the liquid pack, a manufacturing method thereof, and an ink cartridge and a printer having the same.
A liquid pack according to an exemplary embodiment includes: a liquid pack main body having a liquid therein and sealed; A liquid discharge portion provided in the liquid pack main body and discharging the liquid to the outside; And a liquid injecting unit spaced apart from the liquid discharging unit in the liquid pack main body and used for injecting the liquid into the liquid pack main body to take out the air in the liquid pack main body and being hermetically sealed.
The liquid injecting unit may include a first housing part having an interior space and provided with a seating part at one end; A second housing part connected to the other end of the first housing part, the second housing part being hollow inside; A first plug portion inserted into the first housing portion to be seated in the seating portion and to seal the inside of the first housing portion; And a second plug portion inserted into the second housing portion and sealing the inside of the second housing portion.
The interior of the first housing portion may have a first cross sectional area and the interior of the second housing portion may have a second cross sectional area that is greater than the first cross sectional area.
And an inner cross-sectional area of the first housing part may be greater than an inner cross-sectional area of the liquid discharge part.
A step may be provided between the first housing part and the second housing part.
The liquid injecting unit may further include an abutment portion which is provided in the second housing portion and is sealed and sealed to a rim of the liquid pack main body.
Wherein the second stopper portion is made of an elastic material and the other end of the second housing portion is provided with a stopper portion to which the other end of the second stopper portion is engaged and one end of the second stopper portion presses the first stopper portion, The stopper portion and the second stopper portion may be in close contact with each other.
The liquid pack may further include a gas filtering part connected to the liquid discharging part in the liquid pack main body and configured to allow liquid in the liquid pack main body to pass therethrough and not to allow gas in the liquid pack main body to pass therethrough.
A method of manufacturing a liquid pack according to an exemplary embodiment includes the steps of bonding and sealing a liquid discharge portion and a liquid injection portion to a liquid pack body, respectively; Injecting a liquid into the liquid pack body through the liquid injecting unit; Closing the first housing part by inserting a first stopper part into the first housing part of the liquid injecting part; Injecting a syringe through the first stopper to take out air in the liquid pack body; And inserting a second stopper portion into the second housing portion of the liquid injecting portion to seal the second housing portion.
And injecting a gas other than the air into the liquid pack body after the air is taken out.
And an inner cross-sectional area of the first housing part may be greater than an inner cross-sectional area of the liquid discharge part.
An ink cartridge according to an exemplary embodiment is an ink cartridge mounted on a printer and supplying ink to the printer, the ink cartridge comprising: an ink pack body provided inside and sealed with ink; An ink ejection unit ejected to the printer; And an ink injecting portion provided in the ink pack body so as to be spaced apart from the ink discharging portion and used to inject the ink into the ink pack body to take out the air in the ink pack body, ; And a case in which the ink pack is accommodated and mounted in the printer.
According to the exemplary embodiment, by separately providing the ink discharging portion and the ink injecting portion in the ink pack body, the ink discharging portion can be used only for supplying ink to the printer, and the ink injecting and sealing can be separately performed through the ink injecting portion . Here, the ink injecting unit is double-closed through the first stopper and the second stopper, so that the ink in the ink pack main body can be prevented from flowing out. Further, by forming the internal passage of the ink injecting portion larger than the internal passage of the ink discharging portion, the ink injecting time into the ink pack main body can be shortened.
In addition, the ink in the ink pack main body is supplied to the printer through the ink discharging portion by the gas filtering portion, and the gas in the ink pack main body is prevented from flowing into the printer, thereby preventing the head of the printer from being damaged, . Particularly, even if bubbles are generated in the ink pack main body due to a temperature change or the like, bubbles can be prevented from flowing into the printer. Further, by providing the air pocket portion in the ink pack body, it is possible to provide a space in which the gas collects in the ink pack body.
