However, as shown in FIGS. 1C and 1D, even when the flow path forming portion 13 is formed by a flexible tube, as shown in FIG. 2E, the flow path forming portion 13 is the flow path 12 The peelable portion 14 may be a portion where the outer surfaces 13f of the folded flow path forming portion 13 facing each other are removably joined.

Hereinafter, the operation of the container 10 of the present embodiment will be described.

As described above, the container 10 of the present embodiment is a container 10 in which the contents are filled in an aseptic state. The container 10 has a main body portion 11 for accommodating the contents and a flow path forming portion having flexibility that allows the flow path 12 to be narrowed and closed while forming a flow path 12 communicating with the inside of the main body portion 11. A peelable portion 14 which is a portion of the flow path forming portion 13 which faces each other and is detachably joined to each other is provided. In the container 10, the flow path 12 is narrowed and closed with the peelable portion 14 joined, and the flow path 12 is opened with the peelable portion 14 peeled off.

In this way, by joining the portions of the flow path forming portions 13 facing each other in a peelable manner to form the peelable portion 14, for example, FIGS. 1A to 1D, FIGS. 2A to 2E, and FIGS. 3A to 3A. As shown in 3E, the flow path 12 formed by the flow path forming portion 13 is narrowed and closed, and the container 10 can be sealed. Therefore, when sealing the container 10, it is not necessary to use a pair of holding portions that mechanically hold the container body as in the conventional medical multi-chamber container, and damage to the container 10 can be prevented.

Further, the peelable portion 14 is a portion of the flow path forming portion 13 that faces each other and is detachably joined. More specifically, as shown in FIGS. 1A to 1D, FIGS. 2A to 2D, and FIGS. 3A to 3E, the peelable portion 14 can be peeled off from the inner surface 12a of the flow path 12 so as to face each other. And, as shown in FIG. 2E, it is a portion that faces each other and is detachably joined, such as the outer surface 13f of the flow path forming portion 13.

Therefore, when a force in a direction away from each other is applied to the portions of the flow path forming portion 13 facing each other and joined to each other, and the force reaches a force capable of peeling off the facing portions of the flow path forming portion 13. The portions of the flow path forming portion 13 facing each other are separated, and the peelable portion 14 is in a peeled state. In the state where the peelable portion 14 is peeled off, the flow path 12 narrowed and closed by the peelable portion 14 is opened. That is, the peelable portion 14 can be peeled off and the flow path 12 communicating with the inside of the main body portion 11 can be opened only by applying a force in the direction away from each other to the portions of the flow path forming portion 13 facing each other. .. Therefore, opening of the container 10 can be facilitated.

The peelable portion 14 is, for example, as shown in FIGS. 2A and 2B, a peelable start portion 14a formed so as to cross the flow path 12 and having a partially narrowed width in the direction 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 peeling start portion 14a, which has a smaller joining area than the other portions of the peelable portion 14, is easily peeled off in the direction crossing the flow path 12. Therefore, the peeling of the peelable portion 14 can be promoted from the peeling start portion 14a as a starting point, and the entire peelable portion 14 can be easily peeled off. Therefore, opening of the container 10 can be facilitated.

The peeling start portion 14a may be formed by partially reducing the adhesive strength of the peelable portion 14 in the direction crossing the flow path 12. In this case, the width of the peelable portion 14 in the direction along the flow path 12 in the direction crossing the flow path 12 may be uniform. As a result, similar to the examples shown in FIGS. 2A and 2B, the peelable portion 14 is promoted to be peeled off from the peelable start portion 14a whose adhesive strength is lower than that of the other portions of the peelable portion 14, and the peelable portion is promoted. The entire 14 can be easily peeled off.

As shown in FIG. 3A, for example, the flow path forming portion 13 has a thin-walled portion 13a having a partially thinned wall thickness, and the peelable portion 14 is formed in the thin-walled portion 13a. As described above, since the thin-walled portion 13a is thinner than the other portions of the flow path forming portion 13, the flow path 12 is narrowed by forming the peelable portion 14 in the thin-walled portion 13a. It becomes easy to close, and the peelable portion 14 can be easily formed. Therefore, when the peelable portion 14 is formed, the force required to narrow the flow path forming portion 13 can be reduced to prevent damage to the container 10.

As shown in FIG. 3B, the flow path forming portion 13 has, for example, 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, and can be peeled off. The portion 14 is provided for each branch portion 13c. As a result, the flow path 12 branched by the flow path forming portion 13 can be formed, and different contents can be accommodated in the main body portion 11 via the branched flow path 12. Further, by peeling 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. In addition, the bonding force of the peelable portion 14 of each branch portion 13c may be changed to make the peelability different. This makes it possible to sequentially open the flow path 12 of each branch portion 13c.

For example, as shown in FIGS. 1A to 1D, the container 10 is housed inside the main body 11 in a state where the peelable portion 14 is joined, and the flow path 12 is pressurized from the outside of the main body 11. It is provided with a peeling medium M for increasing the internal pressure of the container. As a result, by pressurizing the peeling medium M housed in the main body 11 from the outside of the main body 11, the internal pressure of the flow path 12 rises, and the portions of the flow path forming portions 13 facing each other and joined to each other. The peelable portion 14 can be peeled off by applying a force in a direction away from each other. 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 the pair of peelable portions 14 formed so as to cross the flow path 12 and the pair of peelable portions 14, and flows. A peeling medium M for increasing 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 is provided. As a result, the internal pressure of the flow path 12 rises by pressurizing the peeling medium M enclosed in the flow path 12 between the peelable portions 14 from the outside of the flow path forming portion 13, and the flow path forming portion 13 The peelable portion 14 can be peeled off by applying a force in a direction away from each other to the portions facing each other and joined. 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 grip portions 13d extending in a direction in which the peelable portion 14 is peeled off. As a result, by gripping the pair of peeling grip portions 13d and pulling them in opposite directions, a force in a direction away from each other is applied to the inner surface 12a of the flow path 12 which is a portion of the flow path forming portions 13 facing each other and joined to each other. It can be allowed to act to peel off the peelable portion 14. Therefore, opening of the container 10 can be facilitated.

As shown in FIG. 2C, for example, the flow path forming portion 13 is provided with four folds 13e that narrow and close the flow path 12 radially from the center 12c of the flow path 12. In this case, as described above, the peelable portion 14 is formed by the inner surfaces 12a of the flow paths 12 facing each other in the folds 13e of the flow path forming portion 13 being detachably joined to each other. As a result, of the four folds 13e, two folds 13e that are not adjacent to each other are pulled in opposite directions, so that the other two folds 13e are separated from each other by the inner surface 12a of the flow path 12 that is opposed to and joined to each other. The peelable portion 14 can be peeled off by applying the force of. Therefore, opening of the container 10 can be facilitated.

The container 10 has, for example, as shown in FIGS. 3D and 3E, a protruding portion 15 that protrudes toward the peelable portion 14 inside the flow path 12. In this case, the protruding portion 15 is fixed to the main body portion 11 or the flow path forming portion 13. As a result, the flow path forming portion 13 or the main body portion 11 is bent, the protruding portion 15 is pushed into the peelable portion 14, and a force in a direction away from each other is applied to the facing and joined portions of the flow path forming portion 13. , The peelable portion 14 can be peeled off.
