Description

  The present invention relates to a standing pouch capable of adjusting the concentration of contents such as concentrated liquid foods and enteral nutrients stored in the pouch.

Conventionally, as a pouch for storing concentrated liquid foods or enteral nutrients that require concentration adjustment according to the patient's condition, there is a pouch provided with a replenishment port for adding moisture etc. separately from the content spout Various proposals have been made. (For example, see Patent Documents 1 and 2)
JP 2003-327259 A JP 2004-284606 A

  The pouch described in Patent Document 1 has a pouring member attached to the body side portion of a standing pouch, and a semi-rigid or hard cylindrical body is embedded in a corner portion above the pouch to form a supply port. However, since this standing pouch uses a pouring member and a replenishing port member that are separate from the pouch, the manufacturing process of the pouch becomes complicated and the manufacturing cost increases, and the pouch is bulky. In addition, there is a problem that the storage cost becomes high.

  The pouch described in Patent Document 2 is provided with a supply port for a diluted component having a fastener at a branch portion branched from the body of a liquid food pouch. In this pouch, although the problem of the standing pouch described in Patent Document 1 is solved, since the pouch itself is not self-supporting, a large space for allowing the patient to lie down when preparing for administration. Need. Further, in order to safely transport or store the pouch, it is necessary to adopt means such as individually storing the pouch in a case. Furthermore, since the filling port for the contents becomes narrow, there is a disadvantage that the productivity is lowered and the cost is increased.

On the other hand, there are known refilling pouches having a content outlet at the bottom of the standing pouch (see Patent Documents 3 and 4), but these pouches do not have a replenishment port separate from the outlet. However, the contents are simply poured out from the spout provided at the bottom and transferred to another container, and the concentration of the contents cannot be adjusted.

FIG. 5A is a perspective view of a pouch filled with contents, FIG. 5B is a schematic longitudinal sectional view in the center of FIG. 6A, and FIG. 6 is a diagram for explaining a state when the pouch is used. is there.
The standing pouch 21 includes a main chamber 2 formed of a body portion of the pouch body, and a sub chamber 23 formed in a branched shape below the top portion 22 of the main chamber 2. A spout 5 made of a cap, spout or the like is provided.

The auxiliary chamber 23 of the standing pouch 21 is formed, for example, by folding the surface material 11 constituting the pouch below the top 22 of the pouch 21 and extending it outward to form the back material of the branched auxiliary chamber 23. The sub-chamber surface material 16 and the peripheral portion are heat sealed. The sub chamber 23 communicates with the main chamber 2, and an easily peelable partition portion 24 is provided on the sub chamber side below the folded portion (branching portion) 25.
Other configurations of the pouch 21 such as the supply port 7 provided in the gusset-shaped bottom 3 of the pouch main body (main chamber) 2 are the same as those of the standing pouch 1 of FIGS.

In this example, the contents stored in the pouch 21 are filled with the powder 26 in the sub chamber 23 and the liquid 27 for dissolving the powder 26 in the main chamber 2.
Filling the main chamber 2 with the liquid 27 is performed by heat sealing after filling with the unsealed top portion 22 as a filling port. The filling of the powder 26 into the sub chamber 23 can be performed from the unsealed top portion 22 or from the spout 5 before the partition portion 24 is sealed.

When using the standing pouch 21 filled with the contents, the main chamber 2 and the sub chamber 23 are placed in a straight line on a horizontal surface such as a desk, and the main chamber 2 filled with the solution 27 is manually placed. When the pressure is pressed, the easily peelable partition portion 24 is peeled off, the solution 27 enters the sub chamber 23, and the powder 26 filled in the sub chamber 23 is dissolved to form a solution.
Next, as seen in FIG. 6, the pouch 21 is inverted and the pouch 21 is suspended through the hook 15 in the suspension hole 10 provided on the side wall of the bottom side of the gusset-shaped bottom 3 (opposite to the branching sub chamber 23). . The subsequent dispensing procedure is the same as that of the standing pouch 1 shown in FIGS.
