[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention relates to an open bag that is divided into a plurality of chambers by a middle partition, wherein the middle partition is protruded. As shown in FIGS. 1 and 2, the partition 2 is provided so as to protrude from the outer bag 3 or another outer bag 4. The degree of the protrusion may be such that the partition 2 can be held by the filling step or opened by suction or the like. When two or more partitions are provided, the degree of protrusion can be changed so that the partitions can be held or opened with distinction. When a plurality of intermediate partitions are provided, the intermediate partitions may be opened at both ends as shown in FIG.
[0008]
1 and 2 show examples of two chambers having different sizes, but the chambers may have the same size, and one of the chambers may be sealed vertically, for example, parallel to AA ′. Alternatively, the intermediate partition may have an arbitrary shape such as a cylindrical shape.
[0009]
The outer bag sheet and the middle partition sheet constituting these open bag bodies may be generally used films, and an appropriate one can be selected according to the components to be filled in each chamber. For example, polyethylene, polypropylene, polyester, polyvinylidene chloride or the like, a laminated film thereof, or a laminated film with an aluminum foil or the like may be used. If necessary, a material having a moisture-proof property and a gas barrier property such as an aluminum vapor-deposited film or a silicon vapor-deposited film can be selected.
[0010]
Such an open bag body, in an open bag body divided into a plurality of chambers by a middle partition, the open bag body that protrudes the middle partition, by sucking the middle partition from any direction, the chamber on the side that is not sucked. Open and fill multiple chambers. In addition, it is also possible to hold the protruding partition, open an arbitrary outer bag, and fill each component.
[0011]
At this time, the method of holding the middle partition may be a general method, and the opening method is not particularly limited.For example, the opening may be performed by using a suction cup or a chuck, or the opening may be performed by suction under reduced pressure or adhesive action. it can. Filling may be performed for each component, or each component may be simultaneously filled. At this time, since the inner partition projects, the chuck or the like can easily grip the outer bag sheet at the time of opening, and at the time of filling, there is an advantage that the inner partition serves as a wall to prevent mixing of other components.
[0012]
When the filling is completed, the outer bag and the inner partition are sealed by bonding or welding. At that time, the protruding middle partition may be cut off, as shown in FIGS. Although FIGS. 3 and 4 do not show the filling material, each chamber is actually swollen with the filling component. Further, a cut line or the like following the cuts 7 and 8 may be provided.
[0013]
In the present invention, in the bag divided into a plurality of chambers by the middle partition, the middle partition may be welded to an arbitrary position between the upper cut and the lower seal portion or the lower cut. As a result, the contents can be taken out at the same time, or they can be taken out individually. For example, in FIGS. 3 and 4, the contents of the two chambers can be simultaneously taken out by opening the upper cut 7 at the same time, while the contents are first opened by the lower cut 8 and the bag is taken out. Can be removed individually by opening the upper cut 7 and removing the contents of another chamber.
[0014]
Although FIGS. 3 and 4 show an example of two chambers, a plurality of chambers can be realized by arbitrarily shifting the length of the partition and the welded portion between the cuts. As an example, FIGS. 5 and 6 show the case of three rooms. In this plan view, a protruding middle partition is provided, but after filling the contents, the outer bag sheet and the middle partition are bonded and welded and sealed to form a bag body. When the bag is opened, the contents in the three chambers can be taken out at once by opening the upper cut 7. On the other hand, at first, the lower cut 8 is opened, the contents are taken out, then the cut is opened at the cut 9, the second contents are taken out, the bag is turned over, and the upper cut 7 is opened, and the three cuts are opened. It is also possible to take out the contents of the eyes individually, for example.
[0015]
FIGS. 7 to 9 show examples of the case of dividing into a plurality of rooms included in the present invention. FIG. 7 is an example of a sectional view when divided into three chambers, FIG. 8 is an example of a sectional view when divided into five chambers, and FIG. 9 is an example of a sectional view when divided into six chambers. The figure is in the same state as the bag of FIG. In this way, it can be dealt with by changing the length of the partition or by changing the welding site according to what is desired to be stored in the bag.
[0016]
In addition, the contents of the bag may be stored as two or more kinds of mixed components separately and used as long as it is necessary to mix and use them at the time of use. And dialysis powder preparations. In recent artificial kidney dialysis, bicarbonate dialysis using sodium bicarbonate has become the mainstream, but in bicarbonate dialysate, bicarbonate ions react with calcium ions and magnesium ions to form insoluble compounds (calcium carbonate, carbonate carbonate). (Metal carbonates such as magnesium), so that it is difficult to form a single agent. Therefore, in a general powder formulation, "A-1 agent" composed of an electrolyte component containing calcium ions and magnesium ions and a pH adjuster, "A-2 agent" of glucose, and hydrogen carbonate of bicarbonate ion It is a three-part composition of powder "B" made of sodium, and dilutes "A-1" and "A-2" in solution A and B in "B" Mixed.
[0017]
Therefore, in the double-chamber container of the present invention, the A-1 agent and the A-2 agent of the powder preparation are separately put into bags of two chambers, or all the components for the liquid A are separated for each component. You can also enter. In addition, as an example of storage in a three-chamber bag, sodium chloride, glucose, the remaining electrolyte can be used, or sodium chloride and glucose, a pH adjuster (for example, a solid organic acid such as citric acid), and the remaining electrolyte. You can also divide them. Further, in addition to the powder preparation for liquid A, it is also possible to simply add "A-1 agent", "A-2 agent", and "B agent". In addition, all components of the powder preparation for artificial kidney dialysis, including baking soda, can be separated and put into each component.
[0018]
【The invention's effect】
As described above, in the present invention, each component can be filled by opening any chamber by holding it at the protruding middle partition portion, sucking the middle partition or the outer bag, etc. It can be mechanized at low cost. At the time of use, the mouth of the bag can be opened simultaneously or individually, and the contents of each chamber can be taken out simultaneously or individually. Don't forget to take out each component, as in a separate container.
