2. Related Art
A carriage for storing ink (print material) for supplying to a printer (printing device) has been well known. Among cartridges like this, there is a cartridge storing ink in a bag-shaped flexible member (for example, see Japanese Laid Open Publication No. 2008-273173). Also, ultraviolet curable ink (UV ink) which is hardened by irradiating ultraviolet light (UV light) is well known for ink used for printing (for example, see Japanese Laid Open Publication No. 2013-18823).
UV ink is good in degree of freedom in selecting a base material and in fast dry, when compared with aqueous ink. For the cartridge storing the UV ink, it is necessary to block sun light and light from the lighting device or the like (ultraviolet light and visible light with wavelength of approximately 300-500 nm (nanometer) including visible light) from reaching the UV ink until other cartridges are exchanged after being equipped on the printer following a distribution process after the cartridge is filed with the UV ink, in order to prevent hardening of the UV ink. UV ink has skin irritation property such that it should be handled with care.
The cartridge of Japanese Laid Open Publication No. 2008-273173 has a problem of hardening the UV ink in the cartridge because it is not planned to store the UV ink.

The supply member 230 forms a flow channel 204, a communicating chamber 206, and a flow channel 208 as a flow channel to flow the UV ink from the liquid containing part 202 to the supply port 234. One end of the flow channel 204 communicates with the liquid containing part 202, and the other end of the flow channel 204 communicates to the communicating chamber 206. The communicating chamber 206 includes a check valve 222 to prevent reverse flow of the UV ink from the communicating chamber 206 to the flow channel 204. One end of the flow channel 208 communicates to the communicating chamber 206, and the other end of the flow channel 208 communicates to the supply port 234. The communicating chamber 206 has a flow channel cross-sectional area which is adequately larger than the flow channel 208 and the flow channel 204. The communicating chamber 206 continuously communicates to the supply port 234 from the liquid containing part 202 for the UV ink to flow, via the flow channel 204 and the flow channel 208.
On the supply member 230, a wall member 224, a plate member 226, an elastic member 227, and a lever member 228 are configured. The wall member 224 constitutes a part of a wall which defines the communicating chamber 206 and forms the communicating chamber 206 with the supply member 230. In the present embodiment, the wall member 224 is a film made of synthetic resin and is welded to the supply member 230. The wall member 224 is urged from inside to outside the communicating chamber 206 by the elastic member 227 via the plate member 226, and is bent on the basis of inside pressure of the communicating chamber 206. The lever member 228 is in contact with the wall member 224 outside the communicating chamber 206, and largely move more than deflection amount of the wall member 224 on the basis of the bent of the wall member 224.
In the present embodiment, the wall member 224 blocks the ultraviolet light and the visible light. In the present embodiment, the wall member 224 is a colored film (for example, a laminated film having a print layer colored in back). In another embodiment, the wall member 224 can be a laminated film including an aluminum layer. In the present embodiment, absorbance of the wall member 224 is equal to or less than 0.0001% (by a measuring method of JIS (Japanese Industrial Standard) K 0115:2004) against equal to or more than 200 nm to equal to or less than 500 nm in wavelength. In another embodiment, the ball member 224 can be a part which passes the ultraviolet light and the visible light.
In the present embodiment, the lever member 228 blocks the ultraviolet light and the visible light. In the present embodiment, the lever member 228 is a part made of synthetic resin same as the supply member 230. In another embodiment, the lever member 228 can be a part made of synthetic resin different from the supply member 230.
The lever member 228 of the cartridge 20 is in contact with a bar-shaped member 772 configured on the holder 70 of the printer 80. The bar-shaped member 772 is urged towards the lever member 228 by an elastic member 773, and is movable on the basis of moving of the lever member 228. On the holder 70, a sensor 776 is configured to detect a position of the bar-shaped member 772. In the present embodiment, the sensor 776 detects the position of the bar-shaped member 772 by optically detect a protrusion section 774 configured on the bar-shaped member 772.
As FIG. 5A shows, in the state in which the cartridge 20 is equipped on the holder 70 and in which the UV ink is not sucked from a side of the printer 80, the wall member 224 of the cartridge 20 bents outwardly the communicating chamber 206 by the urge of the elastic member 227 in order to increase the capacity of the communicating chamber 206. With the increase of the capacity of the communicating chamber 206, the UV ink flows to the communication chamber 206 form the liquid containing part 202 via the flow channel 204.
In a state shown in FIG. 5A, when the UV ink is sucked to a side of the printer 80, the UV ink is supplied to the supply needle 730 via the supply port 234, and inside pressure of the communicating chamber 206 becomes lower than atmosphere pressure, as flowing-out amount of the UV ink to the communicating chamber 206 from the flow channel 204 does not catch up flowing-in amount of the UV ink to the flow channel 208 from the communicating chamber 206. By this, the wall member 224 of the cartridge 20 is bent towards inside of the communicating chamber 206, as shown in FIG. 5B.
In a case in which the UV ink is contained in the liquid containing part 202 of the cartridge 20 enough, negative pressure which occurs in the communicating chamber 206 is gradually diminished by the UV ink of the liquid containing part 202 flowing into the communicating chamber 206 via the flow channel 204. With diminishing of the negative pressure in the communicating chamber 206, the wall member 224 of the cartridge 20 is bent, as shown in FIG. 5A, towards outside of the communicating chamber 206.
In a case in which the UV ink is not contained in the liquid containing part 202 of the cartridge 20 enough, because the UV ink is not supplied from the liquid containing part 202 to the communicating chamber 206, negative pressure occurring in the communicating chamber 206 is not diminished. Thus, the wall member 224 of the cartridge 20 maintains a state in which the communicating chamber 206 is bent inwardly, as shown in FIG. 5B. In the present embodiment, the printer 80 detects a state shown in FIG. 5B by using the sensor 776, and when a prescribed time elapses in the state shown in FIG. 5B, it is notified that the cartridge 20 should be exchanged.

A-3 Effect
According to a description of the first embodiment, in the liquid containing body 40 (FIG. 2C), because the light shielding property is attained by the bag 410, it is possible to enhance material and degree of freedom in design of shapes of the flexible member 210 and the supply member 230. Also, in the liquid containing body 30 (FIG. 2B) with the bag 310 being removed from the bag 410, because the user can confirm the leakage of the UV ink from outside of the bag 310, it is possible to prevent the user from making contact to the UV ink.
Also, the flexible member 210 and supply member 230 which are sealed in the bag 310 is in the bag 410. For this reason, when compared with the case in which the bag 410 is sealed, it is possible to prevent the bag 310 from being damaged when the bag 410 is opened because the user easily open the bag 410. As a result, in a state in which the UV ink is leaked inside the bag 310, it is possible to prevent the user from being contact with the UV ink due to damaging the bag 310 when the bag 410 is opened.
Also, because the bag 310 is housed in the bag 410 in a state in which the bag 410 having the light shielding property is bent or partially closed, the user can easily open the bag 410 in this case compared with the case in which the bag 410 is sealed. For this reason, it is possible to prevent the bag 310 from being damaged by mistakenly opening the bag 410, and it is possible to enhance the light shielding property against the UV ink. As a result, in the state in which the UV ink is leaked inside the bag 310, it is possible to prevent the user from being in contact with the UV ink and inhibit hardening the UV ink by the damage of the bag 310 in opening the bag 410.
Also, because the supply member 230 blocks the ultraviolet light and the visible light, it is possible to prevent the UV ink from being hardened by the ultraviolet light and the visible light passing through the supply member 230, in the state in which the bag 410 is removed.
Also, because the light shielding property is attained by the housing 270 in the state in which the bag 410 is removed, it is possible to enhance the degree of freedom in design of the flexible member 210 without limitation in attaining the light shielding property.
Also, the supply member 230, the wall member 224, and the lever member 228 block the ultraviolet light and the visible light, it is possible to prevent the UV ink from being hardened by the ultraviolet light and the visible light passing through the supply member 230, the wall member 224, and the lever member 228, in the state in which the bag 410 is removed.
Also, for the liquid containing body 40, the absorbance in a range from the outside of the bag 410 to the inside of the flexible member 210 in the liquid containing body 40 is equal to or less than 0.0001% against equal to or more than 200 nm to equal to or less than 500 nm in wavelength. For this reason, it is possible to attain the light shielding property enough to block hardening the UV ink.
