The outer container 100 may be formed with an inlet (not shown) so that the fluid can be received or discharged. The outer container 100 may have a receiving part 120 recessed in one direction (preferably, lower side) in the direction of the first inner space 110. The receiving portion 120 can receive the fitting portion 310 described later.

When a plurality of outer vessels 100 are stacked, one outer vessel 100 may be rotated relative to the other outer vessel 100, which may result in a stacking failure. Therefore, the outer container 100 may be provided with rotation preventing means. For example, the anti-rotation means may be a protrusion 130 and a recessed groove 140 disposed on the surface of the outer container 100. In other words, as shown in the figure, a concave groove 140 is formed on the lower side of the outer container 100, a protrusion 130 is formed on the upper side of the outer container 100, The protrusion 130 of one of the outer containers 100 can be prevented from being rotated by being inserted into the recessed groove 140 of the other outer container 100. [

The outer vessel 100 may include a check valve 150. For example, since the check valve 150 is installed in the outer vessel 100, the fluid contained in the first inner space 110 can be discharged to the outside through the discharge unit 300, which will be described later, . That is, when the fluid is discharged from the outer container 100, the pressure of the first inner space 110 is lowered, so that the discharge of the fluid may not be easy. Accordingly, the check valve 150 is opened or closed according to the intention of the user, so that the first internal space 110 can be communicated with the outside of the external container 100 to maintain a predetermined pressure in the first internal space 110.

The outer container 100 may include a bottom member 160. The outer container 100 is provided with a receiving portion 120 for preventing interference with the fitting portion 310 described later when the outer container 100 is stacked. The end portion of the pipe 320, which will be described later, , The fluid may not be completely discharged from the first inner space 110, but a part may remain. Accordingly, the user can prevent the fluid from being thrown away by making the height of the fluid received in the first inner space 110 higher than the height of the receiving portion 120 by providing the bottom member 160 . Preferably, the bottom member 160 is formed in a tapered shape with its top surface forming an inclined surface (not shown). More preferably, the portion converging on the inclined surface may be arranged to correspond to the end of the pipe 320 described later.

When the fitting portion 310 is installed in the outer container 100, the fitting portion 310 may protrude from the outer surface of the outer container 100 toward the outside. When the plurality of outer containers 100 are stacked on each other, the fitting portion 310 disposed in one outer container 100 is received in the receiving portion 120 of the other outer container 100, It is possible to prevent interference between the outer containers 100.

The fitting portion 310 may be provided with a check valve 313 on one side thereof. If the disposable liquid containing apparatus according to the first embodiment of the present invention is fallen, the fluid contained in the fluid container 200 may flow out through the through hole 311 of the fitting portion 310, In order to prevent this, a check valve 313 may be provided, and even if the present invention is toppled by an external force, the fluid contained in the fluid container 200 can be prevented from flowing out by the check valve 313 have. The check valve 313 is opened when a negative pressure is generated in the fluid container 200 accommodating the pipe 320 to be described later and communicated with the outside so that the inside of the fluid container 200 is connected to a predetermined If it is higher than the pressure, the communication with the outside can be disconnected by closing.

The pipe 320 has a tubular shape and is engaged with the fitting portion 310 and can communicate with the through hole 311 of the fitting portion 310. The pipe 320 is extended to be received in the first inner space 110 of the outer container 100. Referring to the drawings, the pipe 320 may be disposed corresponding to the position of the receiving portion 120. However, the present invention is not particularly limited thereto, and the position of the discharge unit 300 may be changed so that the pipe 320 avoids the accommodating portion 120, or the end of the pipe 320 may be bent It is also possible to avoid the bottom part 160 of the outer container 100 from the receiving part 120 by facing the bottom of the outer container 100. In this case, have.

Although the inlet of the fluid container 200 is shown and sealed by heat sealing or clamping in the second embodiment of the present invention, the inlet of the fluid container 200 is different from the fitting portion 310 by various methods. As shown in Fig.

The discharge tube 330 may be coupled to the fitting portion 310 to discharge the fluid inside the fluid container 200 (see FIG. 4). In other words, the fitting portion 310 is provided with the first socket portion 312 and the discharge pipe 330 is provided with the second socket portion 332 at the end thereof. The first socket portion 312, (332) may be coupled to each other. The first socket portion 312 can be coupled with and separated from the second socket portion 332 in a one-touch manner.

The pipe 320 may be installed in the fitting portion 310 to be accommodated in the second inner space 210 of the fluid container 200. That is, the pipe 320 is connected to the through hole 311 formed in the fitting part 310, and the pipe 320 is disposed inside the fluid container 200. Preferably, the pipe 320 extends to a position adjacent to the bottom surface of the fluid container 200, and the end of the pipe 320 may be formed obliquely.
