DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved flexible multi-chamber container for enclosing a powder, a liquid or a solid.

[0002]

2. Description of the Related Art A flexible multi-chamber container having a communicating partition means conventionally used in a medical field is usually made of a synthetic resin, so that a very small amount of it is used. While they tend to transmit moisture and gas.
Therefore, for example, in order to store a multi-chamber container containing a hygroscopically unstable drug (eg, an antibiotic) or the like and a solution such as a dissolving solution or a diluting solution, it is necessary to store moisture, It is necessary to store the gas barrier film in an outer bag, but the desiccant absorbs the water content of the liquid, so that the hygroscopic drug cannot be dried sufficiently and the liquid concentrates. Has not been performed conventionally. Therefore, drugs such as antibiotics that are unstable over time are stored in a container such as a vial that is impermeable to water and gas, and a solution such as a physiological saline solution or a glucose solution that is separately stored at the time of use is used. It is customary to administer to a patient by mixing or dissolving or diluting with a diluent. However, in the above method, since the operation is complicated and there is a risk of bacterial contamination at the time of operation, the puncture needle is used to insert a vial containing an unstable antibiotic over time and a synthetic resin-made flexible container containing a lysis solution. (Japanese Patent Application Laid-Open No. 2-1277). However, this container has the advantage that the mixing operation can be performed easily and aseptically, but at the time of disposal, it takes a lot of trouble to separate the glass vial, the flexible container and the communication device, and the disposal process is difficult. There is a problem that it is difficult to satisfy the demand for easy treatment of medical wastes which is currently being highlighted. In the case of a multi-chamber container containing an oxidizing agent such as an amino acid solution containing tryptophan and a sugar / electrolyte solution (Japanese Patent Publication No. 63-20550), together with a deoxidizer, They must be stored in expensive water and gas barrier outer bags. In this case, since the agent (sugar / electrolyte solution) which does not need to act on the oxygen absorber is also added, the space volume is increased, and the oxygen absorber having a large oxygen absorption capacity is used or a large amount of oxygen is removed. In addition, the use of a chemical agent requires a large amount of an outer bag having moisture and gas barrier properties, resulting in high costs.
The present invention has been made in view of such circumstances, and an object of the present invention is to store a liquid agent, a powder agent, or a solid agent in a multi-chamber container and store the desiccant or the oxygen absorber in a hygroscopic manner. It is an object of the present invention to provide a multi-chamber container which can act on only a liquid agent, a powder agent or a solid agent having high oxidizability and can easily treat waste.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. 1 and 2, reference numeral 2 denotes a chamber for accommodating the liquid agent 4, and 6 denotes a chamber for accommodating the powder agent 8 and the like. The liquid agent 4 is sealed in the chamber 2 and the mouth 10 is attached thereto, while the chamber 6 is composed of a double wall of the outer wall 12 and the inner wall 14, and the powder agent 8 is sealed in the space 13 inside the inner wall 14. A desiccant 16 and an oxygen absorber 18 are sealed in a space 15 between the outer wall 12 and the inner wall 14. As shown in FIG. 3, the inner wall 14 has an outer layer 20 made of polyethylene (hereinafter abbreviated as PE), PE and polypropylene (hereinafter abbreviated as PP).
And a multilayer film having an inner layer 22 made of a mixed resin of
Is formed.

[0006] The one-sided chamber 2 is formed by welding the two multilayer films constituting the inner wall 14 downward and welding them. That is, the two multilayer films are overlapped, and the peripheral edge portion is welded, and the intermediate portion is laterally welded so that the strength becomes smaller than the peripheral edge portion, thereby forming a weak seal portion 24 as a partitioning means. The space 13 and the chamber 2 are formed with the weak seal 24 as a boundary.

As shown in FIG. 4, the outer wall 12 is a multilayer film comprising an inner layer 26 of PE and an outer layer 28 of a moisture-impermeable and gas-impermeable barrier film. As the barrier film, for example, polyethylene terephthalate (hereinafter referred to as PET) is used. ) And a triple layer of polyvinylidene chloride and PE, or a triple layer of PET, a polyvinyl alcohol vapor-deposited silica film and PE. On the outer wall, the two multilayer films are arranged so as to cover the inner wall 14, and the left, right and upper portions are welded to each other.
The lower portion is overlapped and welded on the weak seal portion 24 to form a sealed structure. At the time of sealing, a desiccant 16 and an oxygen scavenger 18 are sealed in a space 15 between the inner wall 14 and the outer wall 12. As the desiccant, for example, silica gel, zeolite, silica gel molded product, integrated oxygen scavenger and the like are used. As the oxygen scavenger, commercially available oxygen absorbers such as “Ageless (registered trademark)” manufactured by Mitsubishi Gas Chemical Company, and oxygen scavengers using amorphous copper can be used.

[0008] In the welding of each part, the welding temperature is:
The peripheral edge of the inner wall 14 and the peripheral edge of the chamber 2 are the highest, the weak seal portion 24 is lower than this, and the inner wall 14 and the outer wall 12
Is set so as to have a temperature intermediate between the peripheral portion and the weak seal portion. As a result, the welding strength is the peripheral portion of the inner wall 14, the chamber 2, and the outer wall 12, and then the welded portion between the inner wall 14 and the outer wall 12, and the weak seal portion 24 is weaker than these.

The multi-chamber container of the above embodiment is manufactured, for example, according to the manufacturing example shown in FIG. That is, (a) the inner layer is a mixed resin of PE and PP, and the outer layer is formed by laminating two multi-layer films of PE to form a weak seal portion 24 by performing peripheral sealing on three sides and sealing to partition an intermediate portion. And
Further, the mouth 10 is attached. (B) Next, the liquid agent 4 is filled, the side part (filling port) is sealed, and heat sterilization is performed. (C) After heat sterilization, the side portion of the empty room 31 is cut to provide a filling port. The inside is dried if necessary.
(D) Next, a multilayer film 32 in which the inner layer is a PE and the outer layer is a double layer of polyvinylidene chloride and PP outside the vacant space 31.
Weld and attach. (E) Then, the desiccant 16 and the oxygen absorber 18 are added to the space inside the inner wall under aseptic conditions.
Is put in the space between the inner wall and the outer wall, and the side (filling port) is sealed. On the other hand, a chemical solution is sealed in the room covered with the outer wall,
As a manufacturing method (not shown) for enclosing a liquid agent or a powder agent in another room, for example, after attaching a mouth portion in the same process as the above-mentioned manufacturing example, each room is filled with each chemical solution, Seal the side (filling port) and sterilize by heating. After heat sterilization, the outer wall is welded, a deoxidizer is put into the space between the inner wall and the outer wall, and the side is sealed.

FIG. 6 shows a more preferable manufacturing example. That is, (a) a hole for an opening is formed in a two-layer film in which the inner layer is a mixed resin of PE and PP and the outer layer is made of PE. (B) Next, after the mouth portion 11 is welded to the hole portion on the PE side, (c) the film is folded around the mouth portion 11 to be in a state of two superposed. (D) Next, the peripheral edge of the superimposed films is welded at a temperature of about 170 to 2 while leaving the filling ports 29 and 30 for enclosing the chemical and the powder.
Seal at 00 ° C. (E) Next, the weak seal portion 24 for partitioning the intermediate portion is formed at a welding temperature of about 110 to 130 ° C. (F) Next, the liquid agent 4 is sealed and the filling port 2 for the chemical liquid is filled.
After sealing both 9 and the filling port 30 for powder agent, high-pressure steam sterilization is performed. (G) After sterilization, the outside of the container is dried, the seal of the powder agent filling port 30 is cut under aseptic conditions, and the inside of the empty chamber 31 is dried and washed with aseptic and dust-free air. (H) Thereafter, the powder is sealed in the empty room 31 under aseptic conditions, and the filling port is sealed. (I) Then, on the outside of the chamber 31, a barrier multilayer film 32,
33 is attached by welding. Here, one of 32 and 33 is preferably transparent and the other is an opaque barrier film. The welding temperature is about 150 when using a transparent film as the gas barrier film.
It is welded at about 170-150 ° C. and about 130-150 ° C. when using an opaque aluminized film. (Nu)
Thereafter, the desiccant 16 and the oxygen absorber 18 are put into the space between the inner wall and the outer wall to seal the side. At this time, it is preferable to perform N ₂ substitution in order to remove oxygen in the space. In the above-mentioned manufacturing examples, the optimum temperature range is selected for the welding temperature of each welding portion depending on the material of the film and the setting of the welding strength, and the like, and is not limited to the above temperature range.

In the embodiment configured as described above, the outer wall 12 is made of a barrier film that is impermeable to moisture and gas and the inner wall 14 is made of PE or an outer layer.
Since the inner layer is composed of a moisture-permeable and gas-permeable multilayer film made of a mixed resin of PE and PP, the desiccant and oxygen scavenger respectively dry the powder and prevent oxidation of the easily oxidizable drug. It can be performed efficiently. Further, the inner wall 14 and the outer wall 12 are transparent, so that the internal state can be visually checked. By applying a certain pressure to the chamber 2 with a finger or the like, the weak seal portion 24 is peeled off, the chamber 2 and the space 13 are communicated, and the liquid agent and the powder agent are mixed and dissolved under aseptic conditions. In addition, as the powder of the above example, for example, antibiotics,
Hygroscopic, easily oxidizable and easily heat-denatured substances such as anticancer drugs, steroids, thrombolytics or vitamins,
Solutions include solutions or diluents thereof, for example, physiological saline, dextrose, and distilled water for injection. Some powdered antibiotics, etc. must be dissolved with an alkaline solvent such as sodium carbonate or other solubilizing agents before dissolving with the lower liquid, but in such cases, An injection port (not shown) for co-injecting a solvent or the like is provided in the chamber containing the powder.

As the inner wall, besides the multilayer film described in the above embodiment, it is also possible to use a single-layer or multilayer film of one or more combinations selected from PE, PP and a resin mixture thereof. Preferably,
The inner layer of the inner wall is made of linear low-density polyethylene (hereinafter LLDP).
E) and PP, and the outer layer is LLD
A two-layer film made of PE can be used. On the outer wall, polyvinylidene chloride, PET, aluminum processed film,
It is also possible to use a single-layer or multilayer sheet of an ethylene vinyl alcohol copolymer (EVOH) or a silica-deposited film. When the inner wall and the outer wall are directly welded, it is desirable that at least the outer wall be a multilayer film and that the material of the innermost layer of the outer wall be the same as the material of the innermost layer or the outermost layer of the inner wall in order to improve the welding. For example, when the outermost layer of the inner wall is LLDPE, the innermost layer of the outer wall is LL.
It is desirable to use DPE. In the above embodiment, the powder is sealed in the room covered with the outer wall, and the liquid is sealed in the room not covered with the outer wall. However, the powder is changed to the liquid according to the purpose, and the liquid is changed to the powder and sealed. Is also possible. Examples of encapsulating a liquid in a room covered with an outer wall and encapsulating a powder in another room include, for example, oxidizable substances such as amino acid preparations to which cysteine or tryptophan is added as a liquid, respectively. Sugar or electrolyte,
Or a mixture thereof. The space 1
5 is filled with only a deoxidizer. An example of enclosing a liquid in a room covered with an outer wall and enclosing another liquid in another room is, for example, an oxidizable substance such as an amino acid preparation or a vitamin preparation to which cysteine or tryptophan is added as the former liquid preparation, respectively. And the latter liquid agent includes a sugar / electrolyte solution. Also, as another example,
Examples of the former solution include an easily oxidizable substance such as a fat emulsion, and examples of the latter solution include a sugar / electrolyte solution. further,
It is also possible to enclose a solid agent in one of the chambers and a liquid agent in the other chamber. Furthermore, examples of the above-mentioned powders, liquids, and solids include various other nutrients and therapeutic agents administered intravenously or enterally (tube or oral). It is also possible to use only one of the desiccant and the oxygen scavenger sealed in the space between the inner wall and the outer wall as necessary. Furthermore, although an aluminum processed film may be used for part or all of the outer wall and the inside may be shielded from light, it is preferable to use an opaque aluminum processed film for the barrier film on the side where the desiccant or oxygen scavenger is sealed. preferable. In addition, a part or all of the aluminum processed film used for the outer wall may be peelable as needed at the time of use. Also, deoxygenation of the space on the transparent barrier film side,
As shown in FIG. 7, a hole 37 may be formed in the welded portion between the inner walls in order to perform the drying well. An opaque sheet 34 may be inserted in order to make the desiccant or oxygen scavenger invisible from the outside and to make it easier to confirm the dissolution state of the powder agent. FIG. 7 shows an example thereof. Note that the sheet 34 is a color in which the dissolution state can be easily confirmed according to the color of the powder agent to be stored, and a sheet having pores opened so as not to hinder the adsorption of oxygen and moisture should be selected. preferable. The opposite side of the insertion of the sheet 34 is transparent, and the inside powder 35 and the like are visible. Also, as shown in FIGS. 8 and 9 , a take-out hole 45 is provided in the outer wall 44, and the outer wall 44 is peelably sealed with a moisture / gas barrier film shielding sheet 46. After use, the shielding sheet 46 is peeled off and dried. The agent 16 and the oxygen scavenger 18 may be taken out. Since waste can be separated for each material, waste disposal becomes easy. Furthermore, the above embodiment is an example of a two-chamber container enclosing a liquid agent and one type of powder agent, but the present invention can be applied to two or more chambers. FIG. 10 shows an example. An inner wall having spaces 38 and 40 for enclosing two kinds of powders (or a powder and a solid) is arranged in the outer wall 36. 42 is a liquid agent. It is also possible to provide a plurality of chambers for enclosing a liquid agent as well as a powder agent or a solid agent.

In the above embodiment, the weak seal portion is formed by a so-called direct welding method in which the inner surfaces of two sheets constituting the inner wall are directly welded to each other. The welding may be performed by a so-called multilayer insert film sandwiching welding method in which the multilayer insert film is welded in a sandwiched state to form a weak seal portion. FIG.
1 shows an example using a two-layer insert film. In this case, 48 is an inner wall made of a single-layer film or a multi-layer film, 50 is a sheet having a strong thermal adhesion to the inner wall or the innermost sheet of the inner wall, and 52 is an inner wall of the opposite inner wall or the innermost layer of the inner wall. On the other hand, the sheet is a sheet having a weak thermal adhesive force, and a weak seal portion 54 is formed. For example, when the inner wall 48 is a single-layer film of PE or PP,
50 is the same PE or PP sheet;
Is a mixed resin of PE and PP. In this example, two films 48 are overlapped and the periphery is welded to form a bag. Instead, a tube-shaped film is used, a hole is made in the middle, and sheets 50 and 52 are inserted therefrom. Then, it is also possible to form a weakly sealed portion by welding while being pressed from the outside of the tubular film. Further, instead of the weak seal portion as a communicable partitioning means constituted by a direct welding method or a multilayer insert film sandwiching welding method, a pipe breakage method can be adopted. That is, as shown in FIGS. 12 and 13, the intermediate portion of the container made of the flexible sheet is welded in a non-peelable state to form the partition 66, thereby partitioning the adjacent chambers and forming the partition 66. Is provided with a communication hole 68, a pipe 70 having one end closed is connected to the communication hole 68, and the pipe 70 is broken at the time of use to enable communication between the two chambers. The outer wall is attached to the partition 66 by welding. Further, as a partitioning means in place of the weak seal portion, a clip system (see Japanese Patent Application Laid-Open No. 63-309263) is adopted in which a flexible sheet is sandwiched between removable clips to partition both chambers. Is also good. In the above embodiment, the outer wall 12 is directly welded at the periphery thereof. However, instead of this, the outer wall 12 may be welded while sandwiching a multilayer insert film, or may be adhered with an adhesive or an adhesive. . Although some embodiments of the present invention have been described above, the present invention is not limited to such embodiments at all, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. It is.

[0014]

Since the present invention is configured as described above, the following effects can be obtained. The space in which the desiccant or oxygen absorber is sealed is isolated from the area that contains liquids that do not require the action of the desiccant or oxygen absorber, so the desiccant absorbs moisture from the liquids and concentrates. In addition to preventing the formation of the oxygen-absorbing agent, the space for enclosing the oxygen-absorbing agent only needs to be present around the portion enclosing the easily oxidizable substance. This is advantageous in that an expensive gas barrier film constituting the outer wall can be reduced. Also, aseptic mixing is possible,
There is an advantage that it is not bulky due to its flexibility. Further, since no glass or metal is used, disposal processing is easy.
