BACKGROUND
There are cases that designs are printed on T-shirts, bathing suits, and the like by an ink-jet method in production of T-shirts, bathing suits, and the like having original designs. In the case where a ground color of a T-shirt or the like is white, a printing may be performed without a pretreatment. In contrast, in the case where the ground color is deep such as black, it is necessary that a design is printed after a discharge-printing treatment. For the discharge-printing treatment, a dedicated discharge-printing treatment agent is used. Many of discharge-printing treatment agents are two-pack type discharge-printing treatment agents each composed of two types of treatment agents. In the two-pack type discharge-printing treatment agent, one of the two types of treatment agents is a reducing treatment agent. Therefore, each of the two types of treatment agents is stored in a different container, and in use, a discharge-printing treatment agent is prepared by mixing the two-types of them.

The embodiments as examples of the present invention are described below with reference to the views. Note here that the present invention is not restricted or limited by the following embodiments.
First Embodiment
The present embodiment is an embodiment in which a second treatment agent is transferred from the second treatment agent-storage container to the first treatment agent-storage container utilizing the negative pressure in the first treatment agent-storage container.
An example of the configuration of the discharge-printing treatment agent storage container of the present embodiment is shown in cross-sectional views of FIGS. 1A to 1E. As shown in FIGS. 1A to 1E, the discharge-printing treatment agent storage container of the present example comprises a first treatment agent-storage container 10 and a second treatment agent-storage container 20. The first treatment agent-storage container 10 is cylindrical, and a ceiling part 14 thereof is provided with an introduction port 12 for introducing a second treatment agent 21. The introduction port 12 is sealed with a seal member 13, so that the inside of the first treatment agent-storage container 10 is shielded from outside air and is under negative pressure. In order to make the inside of the first treatment agent-storage container 10 under negative pressure, gas in the first treatment agent-storage container 10 is exhausted by being vacuumed by a vacuum pump, for example, or an agent for absorbing oxygen is placed in the first treatment agent-storage container 10. A first treatment agent 11 is stored in the first treatment agent-storage container 10. A side wall 15 of the first treatment agent-storage container 10 is extended upward from the ceiling part 14, and the inner side of the side wall 15 is provided with thread grooves 16. The second treatment agent-storage container 20 is approximately cylindrical, the upper part thereof is opened, and the outer side of a side wall of the second treatment agent-strange container 20 is provided with screw threads 24 corresponding to the thread grooves 16. An upper part on the outer side of the side wall of the second treatment agent-storage container 20 is provided with a handle 25 capable of rotating the second treatment agent-storage container 20. A bottom part of the second treatment agent-storage container 20 is provided with a discharge port 22 for discharging a second treatment agent 21. The discharge port 22 is linked to a discharge tube (a needle in the present embodiment) 23.
A method for using the discharge-printing treatment agent storage container of the present example is described below. First, as shown in FIG. 1A, a second treatment agent-storage container 20 is placed on a first treatment agent-storage container 10 with a certain distance. Specifically, the second treatment agent-storage container 20 is screwed into a side wall 15 using a handle 25 until a needle 23 reaches in front of a seal member 13. In the discharge-printing treatment agent storage container of the present example, a mark indicating how far the second treatment agent-storage container 20 should be screwed into is provided on the outer side of the side wall 15 of second treatment agent-storage container 20.
Then, as shown in FIG. 1B, a second treatment agent 21 is filled in the second treatment agent-storage container 20.
Thereafter, as shown in FIG. 1C, the second treatment agent-storage container 20 is screwed into the side wall 15 using the handle 25 until the bottom surface thereof is in contact with the seal member 13. Thus, the needle 23 penetrates the seal member 13, and the tip of the needle 23 is placed in the first treatment agent-storage container 10. In this case, the inside of the first treatment agent-storage container 10 is under negative pressure, so that the second treatment agent 21 is transferred from the second treatment agent-storage container 20 to the first treatment agent-storage container 10 by atmospheric pressure. In this case, as shown in FIG. 1D, a small amount of the second treatment agent 21 remains in the second treatment agent-storage container 20, so that a discharge-printing treatment agent 30 prepared by mixing a first treatment agent 11 and the second treatment agent 21 is shielded from outside air.
After completion of the transfer of the second treatment agent 21, as shown in FIG. 1D, a cylindrical transport tube 31 for a discharge-printing treatment agent, the bottom part of which has been opened, is inserted into the second treatment agent-storage container 20.
After discharging the small amount of the second treatment agent 21 remaining in the second treatment agent storage container 20, as shown in FIG. 1E, the opening of the bottom part of the transport tube 31 is brought into contact with the discharge port 22. Thereafter, the discharge-printing treatment agent 30 is transported to the outside using the transport tube 31.
In the present example, the discharge-printing of fabric such as a T-shirt may be performed by applying the discharge-printing treatment agent 30 by an ink-jet method, a spraying method, a stamping method, a brushing method, or a rolling method. With respect to the discharge-printing of fabric, the same may apply to the other examples of the present embodiment and the other embodiments.
Another example of the configuration of the discharge-printing treatment agent storage container of the present embodiment is shown in cross-sectional views of FIGS. 2A to 2D. In FIGS. 2A to 2D, the identical parts to those in FIGS. 1A to 1E are indicated by identical reference numerals. As shown in FIGS. 2A to 2D, the configuration of the discharge-printing treatment agent storage container of the present example is the same as that shown in FIGS. 1A to 1E except that a second treatment agent 21 is previously filled in a second treatment agent-storage container 20, and an upper opening of the second treatment agent-storage container 20 is sealed with a seal member 26.
A method for using the discharge-printing treatment agent storage container of the present example is described below. First, as shown in FIG. 2A, a second treatment agent-storage container 20 is placed on a first treatment agent-storage container 10 so that a needle 23 is in front of a seal member 13.
Then, as shown in FIG. 2B, the second treatment agent-storage container 20 is screwed into a side wall 15 using a handle 25 until the bottom surface thereof is in contact with the seal member 13. Thus, the needle 23 penetrates the seal member 13, and the tip of the needle 23 is placed in the first treatment agent-storage container 10. Thereafter, a seal member 26 with which an upper opening of the second treatment agent-storage container 20 has been sealed is removed. In this case, the inside of the first treatment agent-storage container 10 is under negative pressure. Therefore, a second treatment agent 21 is transferred from the second treatment agent-storage container 20 to the first treatment agent-storage container 10.
Subsequently, as shown in FIGS. 2C and 2D, the same operations as shown in FIGS. 1D and 1E are performed.
Yet another example of the configuration of the discharge-printing treatment agent storage container of the present embodiment is shown in cross-sectional views of FIGS. 3A to 3E. In FIGS. 3A to 3E, identical parts to those in FIGS. 1A to 1E are indicated by the identical reference numerals. The present example is an example in which a second treatment agent is transferred from a second treatment agent-storage container to a first treatment agent-storage container by applying pressure with a transport tube besides negative pressure in the first treatment agent-storage container. As shown in FIGS. 3A to 3E, in the discharge-printing treatment agent storage container of the present example, a diameter of an upper opening of a second treatment agent-storage container 20 is increased at its upper end part in order for a transport tube 31 to be easily inserted therein. Moreover, the discharge-printing treatment agent storage container of the present example is provided with a receiving groove 27 for receiving an overflow of a second treatment agent 21 from the upper end part of the upper opening of the second treatment agent-storage container 20 when the transport tube 31 is inserted.
A method for using the discharge-printing treatment agent storage container of the present example is described below. First, as shown in FIG. 3A, a second treatment agent-storage container 20 is screwed into a side wall 15 using a handle 25 until a needle 23 reaches in front of a seal member 13 in the same manner as in FIG. 1A.
Then, as shown in FIG. 3B, a second treatment agent 21 is filled in the second treatment agent-storage container 20 up to the upper end part of the upper opening.
Thereafter, as shown in FIG. 3C, the second treatment agent storage container 20 is screwed into the side wall 15 using the handle 25 until the bottom surface thereof is in contact with the seal member 13, so that the needle 23 penetrates the seal member 13, and the tip of the needle 23 is placed in the first treatment agent-storage container 10. Subsequently, a transport tube 31 is placed so as to be in contact with the upper surface of the second treatment agent 21.
Then, as shown in FIG. 3D, the second treatment agent 21 is transferred from the second treatment agent-storage container 20 to the first treatment agent-storage container 10 by applying pressure with the transport tube 31 besides negative pressure in the first treatment agent-storage container 10. According to the present example, the second treatment agent 21 may be transferred in a short time. Moreover, an overflow of the second treatment agent 21 from an upper end part of an upper opening of the second treatment agent-storage container 20 is received by a receiving groove 27, so that there is no case that a surrounding area of the discharge-printing treatment agent storage container gets dirty with the second treatment agent 21.
Subsequently, as shown in FIG. 3E, the same operation as shown in FIG. 1E is performed.
Second Embodiment
The present embodiment is an embodiment in which a second treatment agent is transferred from a syringe that is a second treatment agent-storage container to a first treatment agent-storage container with a piston.
An example of the configuration of the discharge-printing treatment agent storage container of the present embodiment is shown in cross-sectional views of FIGS. 4A to 4E.

The discharge port 52 is linked to a discharge tube 53.
A method for using the discharge-printing treatment agent storage container of the present example is described below. First, as shown in FIG. 4A, a second treatment agent 51 is drawn into a syringe 50.
Then, as shown in FIG. 4B, the tip of a discharge tube 53 is placed in a first treatment agent-storage container 40 by opening a first check valve 43 through inserting a discharge tube 53 into an introduction port 42.
Thereafter, as shown in FIG. 4C, the second treatment agent 51 in the cylinder 50 is transferred to the first treatment agent-storage container 40 by applying pressure to the second treatment agent 51 with a piston 54 under the state where the tip of the discharge tube 53 is placed in the first treatment agent-storage container 40. In this case, inactive gas is exhausted from an exhaust port 45 by opening a second check valve 46 according to the transfer of the second treatment agent 51.
Then, as shown in FIG. 4D, by pulling the tip of the discharge tube 53 out of the introduction port 42, the introduction port 42 is sealed with the first check valve 43, and the exhaust port 45 is sealed with the second check valve 46. Therefore, a discharge-printing treatment agent 60 prepared by mixing a first treatment agent 41 and the second treatment agent 51 is shielded from outside air.
Subsequently, as shown in FIG. 4E, a transport needle 62 that is placed at the tip of a transport tube 61 is inserted into the introduction port 42, so that the first check valve 43 is opened. Then, under this state, the discharge-printing treatment agent 60 is transported to the outside.
Another example of the configuration of the discharge-printing treatment agent storage container of the present embodiment is shown in cross-sectional views of FIGS. 5A to 5E. In FIGS. 5A to 5E, identical parts to those in FIGS. 4A to 4E are indicated by the identical reference numerals. The present example is an example in which a first treatment agent-storage container is provided with an introduction path for a discharge tube. As shown in FIGS. 5A to 5E, the discharge-printing treatment agent storage container of the present example comprises a first treatment agent-storage container 40 and a cylinder (second treatment agent-storage container) 50 capable of inserting a piston 54 therein. The first treatment agent-storage container 40 has a tubular shape such as a cylindrical shape or a rectangular-tube like shape. A bottom part 47 of the first treatment agent-storage container 40 is provided with an introduction port 42 for introducing a second treatment agent 51. The first treatment agent-storage container 40 is provided with a first treatment agent storage part 48. The side part of the first treatment agent storage part 48 is provided with an introduction path 49 extended from the introduction port 42 toward the inside of the first treatment agent-storage container 40. The boundary between the first treatment agent storage part 48 and the introduction path 49 is sealed with a first check valve 43, so that the inside of the first treatment agent-storage container 40 is shielded from outside air and is under an atmosphere of inactive gas. The inactive gas is the same as mentioned above. A ceiling part of the first treatment agent-storage container 40 is provided with an exhaust port 45 for exhausting the inactive gas. The exhaust port 45 is sealed with a second check valve 46. A first treatment agent 41 is stored in the first treatment agent storage part 48. The configuration of the cylinder 50 is the same as that in the discharge-printing treatment agent storage container shown in FIGS. 4A to 4E.
A method for using the discharge-printing treatment agent storage container of the present example is described below. First, as shown in FIG. 5A, a second treatment agent 51 is drawn into a cylinder 50.
Then, as shown in FIG. 5B, the tip of a discharge tube 53 is placed in front of a first check valve 43 by inserting the tip of the discharge tube 53 from an introduction port 42 to an introduction path 49.
Thereafter, as shown in FIG. 5C, the second treatment agent 51 is transferred to a first treatment agent-storage container 10 by opening the first check valve 43 through applying pressure to the second treatment agent 51 that is in the cylinder 50 with a piston 54 under the state where the tip of the discharge tube 53 is placed in front of the first check valve 43. In this case, inactive gas is exhausted from an exhaust port 45 by opening a second check valve 46 according to the transfer of the second treatment agent 51.
Subsequently, as shown in FIG. 5D, by pulling the tip of the discharge tube 53 out of the introduction path 49 and the introduction port 42, the boundary between a first treatment agent storage part 48 and the introduction path 49 is sealed with the first check valve 43, and the exhaust port 45 is sealed with the second check valve 46. Therefore, a discharge-printing treatment agent 60 prepared by mixing a first treatment agent 41 and the second treatment agent 51 is shielded from outside air.
Then, as shown in FIG. 5E, a transport needle 62 that is placed at the tip of a transport tube 61 is caused to penetrate the second check valve 46, so that the tip of the transport needle 62 is inserted into the first treatment agent storage part 48. Thereafter, the discharge-printing treatment agent 60 is transported to the outside.

The first introduction port 81 is sealed with a first check valve 83, and the second introduction port 82 is sealed with a second check valve 84, so that the inside of the first treatment agent-storage container 80 is shielded from outside air and is under negative pressure. A method for causing the inside of the first treatment agent-storage container 80 to be under negative pressure is as mentioned above. The first treatment agent-storage container 80 is provided with needles 87 and 88 at the respective positions on the bottom part 86, corresponding to the second introduction port 81 and the first introduction port 82 of the ceiling part 85. A side wall of the first treatment agent-storage container 80 is provided with a discharge port 89 for transporting a prepared discharge-printing treatment agent 120 to the outside. The discharge port 89 is sealed with a seal member 90. The second treatment agent-storage container 100 has a tubular shape such as a cylindrical shape or a rectangular-tube like shape, and the upper part thereof is opened. A bottom part thereof is provided with a discharge port 102 for discharging the second treatment agent 101. The discharge port 102 is linked to a discharge tube 103. A bottom part of the discharge tube 103 is sealed with a seal member 104. The first treatment agent-supply container 110 has a tubular shape such as a cylindrical shape or a rectangular-tube like shape. The bottom part of the first treatment agent-supply container 110 is provided with a discharge port 112 for discharging the first treatment agent 111. The discharge port 112 is linked to a discharge tube 113. The bottom part of the discharge tube 113 is sealed with a seal member 114, so that the inside of the first treatment agent-supply container 110 is shielded from outside air and is under an atmosphere of inactive gas. The inactive gas is the same as mentioned above.
A method for using the discharge-printing treatment agent storage container of the present embodiment is described below. First, as shown in FIG. 9B, the tips of discharge tubes 103 and 113 are placed in a first treatment agent-storage container 80 by opening a second check valve 84 and a first check valve 83 through inserting the discharge tubes 103 and 113 into a second introduction port 82 and a first introduction port 81, respectively. In this case, a needle 88 penetrates a seal member 104, and a needle 87 penetrates a seal member 114. Therefore, since the inside of the first treatment agent-storage container 80 is under negative pressure, a second treatment agent 101 is transferred to the first treatment agent-storage container 80 by atmosphere pressure, and a first treatment agent 111 is transferred to the same by pressure of the inactive gas.
Then, as shown in FIG. 9C, a transport needle 122 placed at the tip of a transport tube 121 is caused to penetrate a seal member 90, so that the tip of the transport needle 122 is inserted into the first treatment agent-storage container 80. Thereafter, a discharge-printing treatment agent 120 is transported to the outside.
It will be obvious to those having skill in the art that many changes may be made in the above-described details of the particular aspects described herein without departing from the spirit or scope of the invention as defined in the appended claims.
