The proximal end is fixed to one side opposite to the side where the is provided, and the distal end extends to the channel 12 formed by the channel forming part 13 and is arranged adjacent to the peelable part 14 . That is, in the example shown in FIG. 3E , the proximal end that is one end of the projecting portion 15 is fixed to the edge side of the body portion 11 shown in FIG. The tip is positioned adjacent to the peelable portion 14 .

In the example shown in FIGS. 3A to 3E, the detachable portion 14 is a portion to which the opposing inner surfaces 12a of the channel 12 are detachably joined. However, as shown in FIGS. 1C and 1D, even when the flow path forming portion 13 is formed of a flexible tube, the flow path forming portion 13 is formed from the flow path 12 as shown in FIG. 2E. The peelable portion 14 is folded back so as to constrict the
may be a portion where the opposed outer surfaces 13f of the folded flow path forming portion 13 are joined so as to be peelable.

The action of the container 10 of this embodiment will be described below.

The container 10 of the present embodiment is, as described above, a container 10 filled with contents in an aseptic state. The container 10 includes a body portion 11 for containing contents, and a flexible flow channel forming portion that forms a flow channel 12 that communicates with the inside of the body portion 11 and that can narrow and close the flow channel 12. 1
3, and a detachable portion 1, which is a portion of the flow path forming portion 13 that is opposed to each other and is detachably joined.
4 and . In the container 10, the channel 12 is constricted and closed with the peelable portion 14 joined, and the channel 12 is open with the peelable portion 14 peeled off.

In this way, the mutually facing portions of the flow path forming portion 13 are joined in a detachable manner to form the detachable portion 1 .
4, for example, FIGS. 1A-1D, 2A-2E, and 3A
3E, the channel 12 formed by the channel forming portion 13 is constricted and closed, and the container 10 can be sealed. Therefore, when sealing the container 10, there is no need to use a pair of clamping parts for mechanically clamping the container body as in a conventional multi-chamber medical container, and damage to the container 10 can be prevented.

In addition, the peelable portion 14 is a portion of the flow path forming portion 13 that is joined to face each other so as to be peelable. More specifically, the peelable portions 14 are opposed and peelable portions of the inner surface 12a of the channel 12, for example, as shown in FIGS. 1A-1D, 2A-2D, and 3A-3E. and, as shown in FIG. 2E, the portions such as the outer surface 13f of the flow path forming portion 13 that face each other and are joined so as to be peelable.

Therefore, a force is applied to the parts of the flow path forming part 13 that face and are joined to each other, and when the force reaches a force capable of separating the parts of the flow path forming part 13 that face each other, The parts of the flow path forming part 13 that face each other are separated, and the peelable part 14 is peeled off. When the peelable portion 14 is peeled off, the channel 12 narrowed and closed by the peelable portion 14 is opened. In other words, by simply applying a force in the direction of separating the parts of the flow path forming part 13 that face each other, the peelable part 14 can be peeled off and the flow path 12 communicating with the inside of the main body part 11 can be opened. . Therefore, opening of the container 10 can be facilitated.

For example, as shown in FIGS. 2A and 2B, the peelable portion 14 is formed to cross the flow path 12 and has a partially narrowed width along the flow path 12. can have As a result, the peeling start portion 14a having a smaller width in the direction along the flow path 12 than the other portions of the peelable portion 14 in the direction crossing the flow path 12 is easily peeled off. In other words, the peel starting portion 14a having a smaller bonding area than the other portions of the peelable portion 14 in the direction crossing the flow path 12 is easily peeled. Therefore, starting from the peeling start portion 14a,
The peeling of the peelable portion 14 is facilitated, and the entire peelable portion 14 can be easily peeled off. Therefore, opening of the container 10 can be facilitated.

Note that the peel start portion 14a may be formed by partially reducing the adhesive strength of the peelable portion 14 in the direction crossing the channel 12 . In this case, the width of the peelable portion 14 in the direction along the flow path 12 may be uniform in the direction across the flow path 12 . As a result, Fig. 2
As in the example shown in A and FIG. 2B , peeling of the peelable portion 14 is accelerated starting from the peel starting portion 14 a having a lower adhesive strength than the other portions of the peelable portion 14 , and the entire peelable portion 14 is peeled off. It can be easily peeled off.

For example, as shown in FIG. 3A, the flow path forming portion 13 has a thin portion 13a whose thickness is partially reduced, and the peelable portion 14 is formed in the thin portion 13a. In this way, the thin portion 1
Since the thickness of the portion 3a is thinner than that of the other portions of the flow path forming portion 13, forming the peelable portion 14 in the thin portion 13a makes it easy to constrict and close the flow path 12. As a result, the peelable portion 14 can be easily formed. Therefore, it is possible to reduce the force required to constrict the flow path forming portion 13 when forming the peelable portion 14 , thereby preventing damage to the container 10 .

For example, as shown in FIG. 3B, the flow path forming portion 13 has a base end portion 13b connected to the main body portion 11 and a plurality of branch portions 13c connected to the base end portion 13b. Part 14 is
It is provided for each branch portion 13c. Thus, the flow path 12 branched by the flow path forming portion 13 can be formed, and different contents can be accommodated in the body portion 11 via the branched flow path 12 . Further, by peeling off the peelable portion 14 of each branch portion 13c, the branched flow paths 12 can be easily opened. Therefore, opening of the container 10 can be facilitated. It should be noted that the ease of peeling may be varied by changing the bonding strength of the peelable portion 14 of each branch portion 13c. Thereby, it is possible to sequentially open the flow paths 12 of the respective branch portions 13c.

For example, as shown in FIGS. 1A to 1D , the container 10 is housed inside the body portion 11 with the peelable portion 14 attached thereto, and pressure is applied from the outside of the body portion 11 to cause the flow path 12 to expand.
It has a stripping medium M for increasing the internal pressure of the. As a result, the internal pressure of the flow path 12 is increased by pressurizing the peeling medium M housed inside the main body 11 from the outside of the main body 11, and the portions of the flow path forming portions 13 facing and joined to each other are increased. can exert a force in directions away from each other to peel off the peelable portion 14 . Therefore, opening of the container 10 can be facilitated.

For example, as shown in FIG. 3C, the container 10 is enclosed in the flow path 12 between a pair of peelable portions 14 formed to cross the flow path 12, and between the pair of peelable portions 14. and a peeling medium M that increases the internal pressure of the flow path 12 between the pair of peelable portions 14 by applying pressure from the outside of the path forming portion 13 . As a result, the peelable portion 14 is separated from the outside of the flow path forming portion 13 .
By pressurizing the stripping medium M enclosed in the channel 12 between
A force in a direction separating from each other can be applied to the parts of the flow path forming part 13 that are opposed to each other and joined together, so that the peelable part 14 can be peeled off. Therefore, opening of the container 10 can be facilitated.

For example, as shown in FIG. 2D, the flow path forming portion 13 may have a pair of peeling grips 13d extending in the direction in which the peelable portion 14 is peeled off. As a result, by gripping the pair of peeling grips 13d and pulling them in mutually opposite directions, a force in the directions separating from each other is exerted on the inner surfaces 12a of the flow paths 12, which are the portions of the flow path forming part 13 that are joined to face each other. The peelable portion 14 can be peeled off. Therefore, opening of the container 10 can be facilitated.

For example, as shown in FIG. 2C, the flow path forming portion 13 has four folds 13e radially extending from the center 12c of the flow path 12 to constrict and close the flow path 12. As shown in FIG. In this case, as described above, the detachable portion 14 is formed by detachably joining the inner surfaces 12a of the flow paths 12 facing each other at the folds 13e of the flow path forming portion 13 . As a result, by pulling two folds 13e that are not adjacent to each other among the four folds 13e in opposite directions, the inner surfaces 12a of the flow paths 12 that face and are joined to each other of the other two folds 13e are pulled in directions away from each other. , the peelable part 14 can be peeled off. Therefore, opening of the container 10 can be facilitated.

The container 10 has a protruding portion 15 protruding toward the peelable portion 14 inside the channel 12, for example, as shown in FIGS. 3D and 3E. In this case, the protruding portion 15 is the main body portion 1
1 or the flow path forming portion 13 . As a result, the flow path forming portion 13 or the main body portion 1
1 is bent to push the protruding portion 15 into the peelable portion 14, and force is applied to the mutually facing and bonded portions of the flow path forming portion 13 in the direction of separating from each other, so that the peelable portion 14 can be peeled off. . Therefore, opening of the container 10 can be facilitated.

For example, as shown in FIG. 3D, the flow path forming portion 13 has an inlet port 16 as a cylindrical port at the tip portion on the side opposite to the main body portion 11, and the protruding portion 15 is provided in the inlet port 16. ing. As a result, the flow path forming portion 13 is bent, and the inlet port 1 at the tip portion of the flow path forming portion 13 is opened.
6 is pushed into the detachable portion 14, and force is applied to the mutually facing and bonded portions of the flow path forming portion 13 in the direction of separating from each other, so that the detachable portion 14 can be detached. Therefore, opening of the container 10 can be facilitated.

Peelable portion 14 is illustrated, for example, in FIGS. 1A-1D, 2A-2D, and 3A.
3E, the opposing inner surfaces 12a of the channel 12 are releasably joined. As a result, by applying a force in a direction separating from each other to the mutually facing and joined portions of the flow path forming portion 13, the mutually facing inner surfaces 12 of the flow paths 12 that are detachably joined can be separated from each other.
a can be peeled off to open the channel 12 narrowed by the peelable portion 14 . Therefore, opening of the container 10 can be facilitated.

For example, as shown in FIG. 2E, the channel forming portion 13 is folded back so as to constrict the channel 12 .
