Description

PARTITIONING MEMBER AND CONTAINER USING THE SAME}

The invention claims benefit under 35.USC § 119 (e) of U.S. Provisional Application No. 60/501031, filed on September 9, 2003, the disclosure of which is incorporated herein by reference on September 3, 2003. Priority to Japanese Patent Application No. 2003-311780, filed on August 11, 2004, Japanese Patent Application Publication No. 2004-234367, and US Patent Provisional Application No. 60 / 501,031, filed on September 9, 2003 Charges.

The present invention relates to a partition member. More specifically, the present invention relates to a partition member that allows for a secure separation of contents, such as pharmaceuticals and foods contained in a plurality of chambers prior to use, and for quickly passing the chamber to mix the contents immediately prior to use, It also relates to a container using the partition member.

For containers used in the medical or food field, containers are known in which a plurality of contents are received in a plurality of chambers and each of the contents are not mixed before use but can be easily mixed at the time of use.

For example, when preparing an infusion medication by mixing a plurality of medications just prior to administration of the infusion medication in the medical field, foreign matter or other bacteria need to be prevented from mixing into the infusion medication. For an infusion container capable of mixing a plurality of medicaments in a sterile environment, the inner wall surface of a bag container formed of a membrane made of synthetic resin is heat sealed by using a seal made as a compartment and the seal inside the bag container. BACKGROUND OF THE INVENTION An infusion vessel having multiple chambers in which a medicament is contained in a plurality of chambers partitioned by is known. According to the infusion container with multiple chambers, the seal which defines each chamber is opened and peeled off to integrate the chamber inside the container into one chamber, whereby each medicine can be mixed.

In such infusion containers with multiple chambers, each medicament is reliably separated from each other until infusion. Therefore, the compartment of the infusion container is required not to be easily opened and peeled off during normal handling prior to injection, for example during cleaning, partial filling, sterilization, storage or movement of an injection container with multiple chambers. On the other hand, the compartment prepared by heat sealing at the time of mixing the medicine is opened and peeled off by itself without damaging the container body.

For a compartment capable of satisfying this requirement, an injection container having multiple chambers using a seal manufactured by detachably heat sealing a synthetic resin film has been proposed. A known example of the proposed seal is an easily peeled seal made by mixing two or more synthetic resins having low compatibility with each other and then thermally bonding the inner surface of the bag container obtained by forming a mixture (Japanese non-examined patent application) , First Publication No. S63-19149) and a seal manufactured by laminating a separator on an inner surface of a container serving as a layer having a function of melt sealing and opening (Japanese Unexamined Utility Model Registration Application, First 1 publication H5-5138).

However, adjustment of the peel strength of the seal in a given low peel strength range is accompanied by narrow tolerances in selecting manufacturing conditions for the seal. Thus, if the manufacturing conditions are outside the predetermined range or the peel strength is smaller than the predetermined low peel strength, the seal is sometimes opened and peeled before injection, whereas if the peel strength exceeds the predetermined low peel strength, the seal It is not easy to open and peel off when mixing drugs.

For an injection container with multiple chambers capable of solving this problem, a container has been proposed in which the partition portion used to partition each chamber is a partition member containing a resin molded product rather than a seal portion. For example, a closed pipe at one end is provided in the communication hole and the pipe is ruptured (Japanese Unexamined Patent Application, First Publication H4-364851, Figs. 12 and 13A and 13B) so that two chambers are in use. In order to be able to communicate, a compartment is disclosed having communication holes formed by melt sealing so that the central portion of the container is not separable. Also disclosed is a partition having a configuration for allowing a separating wall having a closed communication hole with a pressure member and a communication hole to be opened by bending the pressure member from the outside of the container (Japanese Unexamined Patent Application, First Publication) H6-197938).

However, the pipe or pressing member provided in the compartment may be damaged before injection by the force imposed from the outside of the container. In addition, in order to be able to rupture the pipe or the pressing member relatively easily, the pipe or the pressing member itself must be made thin by reducing the hole diameter, but it entails confined conditions in the flow of the medicine through the communication holes and The mixing operation is problematic in that it takes time.

With respect to the partition member which can solve the problem in the partition member made of conventional resin, a lid body for stopping one end of the hollow portion and the hollow portion that can pass through two containers is formed, and a thin membrane portion is formed of the lid body and the partition member. There is a disclosed partition member (Japanese Unexamined Patent Application, First Publication No. 2001-87350) formed at a connection between main bodies.

Fig. 12 shows an example of an injection container provided with multiple chambers according to the invention of Japanese Unexamined Patent Application No. 2001-87350 using this partition member. The container 21 of the example incorporates a second housing portion 23 having an interior of the chamber for containing the powdered medicine and a first housing portion 22 having an interior of the chamber for containing the liquid medicine. This container is obtained by having a partition member 24 for partitioning the first housing portion 22 and the second housing portion 23.

The partition member 24 is formed long and flat in the cross direction of the container 21. A partition member main body 24a having a hollow portion capable of passing through the first housing portion 22 and the second housing portion 23 and a lid body 24b provided in the opening of the partition member main body 24a; The opening of the partition member 24 has a boat-shaped cross section.

In the partition member 24, forces in the same direction are applied to both ends of the partition member 24 toward the thickness direction of the container, and the force is the direction described above for bending the partition member 24 in a dogleg shape. It is similarly applied to the central portion of the partition member 24 in a direction opposite to, whereby the thin wall portion 24c formed at the connection between the lid body 24b and the partition member main body 24a can be ruptured, and the lid The main body 24b can be opened to the outside of the partition member. After opening of the lid, the first housing portion 22 is pressurized to move the liquid medicament, thereby peeling open the weak seal 25 adjacent the second housing portion 23 and consequently, the first housing. The part 22 and the second housing part 23 are in communication and the two medicaments may be mixed.

The partition member of Japanese Unexamined Patent Application, First Publication No. 2001-87350 shows that the thin wall portion 24c does not rupture to open the lid body and allow two containers to pass when a force is applied to the entire container. The thin walled portion 24c opens the lid body and partitions because it is characterized by wide area and rapid mixing of the contents and by applying force to the partition member main body 24a and causing large bending deformation. It ruptures to allow two housing parts through the member.

In manufacturing the container with multiple chambers used in Japanese Unexamined Patent Application, First Publication No. 2001-87350, the support member for maintaining the shape of the hollow portion of the partition member is not formed with the lid body 24b. It is inserted from the opening in the side. By inserting the supporting member, the shape of the hollow portion of the partition member main body can be maintained when melt sealing the container to the partition member, and the plurality of containers can be melt sealed to the partition member without a gap. However, this partition member may be detached from the main body of the partition member prior to melt sealing the container to the partition member, and the container cannot be melt sealed to the partition member or the support member or lid after the contents have been filled into the container. The main body 24b has a problem in that it may fall out of the partition member or float out of the container, or the lid main body 24b may be regarded as a foreign matter.

In addition, in manufacturing a container using the partition member described in Japanese Unexamined Patent Application, First Publication No. 2001-87350, the insertion of the support member is mainly the basic, and therefore, the manufacturing process removes and inserts the support member. It is necessary to include a step.

Also, at this stage, the supporting jig made of metal is often used for the supporting member, which may cause a problem that resin powder is generated on the contact portion between the supporting jig and the partition member made of resin, and the resin powder is used to remove foreign substances inside the container. It can cause problems.

The present invention has been made under such circumstances, and an object of the present invention is to provide a partition member capable of melt sealing a plurality of containers without gaps in a partition member without a support member. Another object of the present invention is to provide a partition member in which no foreign matter is generated in the container after being brought into contact with the container. It is another object of the present invention to provide a container using a partition member in which the contents contained in the plurality of containers can be quickly separated before use and can be easily mixed while the respective contents remain sterile in use. .

The present invention has intensively studied a partition member capable of realizing the above-mentioned object, that is, for example, two containers can be melt-sealed to the partition member without a support member, and consequently the hollow part of the partition member main body is partitioned. To this end, the partition body is provided at a portion except both ends of the hollow portion, so that the shape of the hollow portion of the partition member main body can be maintained even if the support member is not inserted, and the plurality of containers can be melt-sealed without gaps in the partition member. Is found. By virtue of this configuration, it is also found that the step of inserting and removing the support member can be omitted, and the container can preferably be manufactured through a simple manufacturing process at low manufacturing cost.

In addition, a thick wall portion is formed in a part of the connection portion between the partition body and the partition member main body, or the support member is melt-sealed in two openings of the partition member main body, and the partition body is in the hollow portion, so that the two containers can pass through. It has been found that the compartment body does not float as foreign matter in the vessel after being set. The present invention has been completed based on this finding.

That is, the first invention of the present invention is a partition member for partitioning a plurality of adjacent housing portions including a partition member for partitioning the hollow portion and a partition member main body having a hollow portion capable of allowing a plurality of adjacent housing portions to pass through.

The invention is explained in detail below with reference to the drawings.

1A and 1B and 2A to 2D show an example of a partition member according to the present invention. 1A and 1B are perspective views of an example partition member, FIG. 2A is a front view, FIG. 2B is a front view, FIG. 2C is a side view, and FIG. 2D is another front view observed from the opposite side in FIG. 2A. The partition member 1 comprises a partition member main body 2 having a partition body 4 for partitioning the hollow part 3 at the center of the hollow part and a hollow part 3 capable of passing through a plurality of adjacent containers. do. The partition body 4 is provided at a portion except for the opening 7 of the partition member main body. The partition body 4 and the partition member main body 2 are connected via a thin wall 5. The example partition member 1 is used as the partition member 24 of the container 21 shown in FIG.

The structural material of the partition member 1 is selected from a synthetic resin that satisfies the requirements that the partition member can deform when stressed without causing damage to the main body of the partition member, and foreign matter is produced after rupture of the thin film portion. And, the partition member can be melt sealed to the film of the container forming material, and satisfies the requirement that the partition member does not dissolve into the content, does not adsorb the content, and does not decompose the content. Specific examples of synthetic resins include polyolefins such as polypropylene and polyethylene, polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate and alicides. Polyesters such as alicyclic copolyesters, thermoplastics such as polysulfone, polyethersulfone and cyclic polyolefins and mixtures thereof. Among these synthetic resins, polyolefins and cyclic polyolefins are preferred because they have good sealing properties in the container forming material and have no effect on the contents. In the case of using polyolefins, high density polyethylene is more preferred.

The partition member main body 2 mainly has a tubular shape and a flat shape. The cross-sectional shape is sufficient if it has a hollow portion through which the plurality of housing portions can pass. In the example of Fig. 1, the cross-sectional shape is in the form of a boat, but the present invention is not limited thereto. At both ends, an opening 7 is provided. The outer surface of the partition member main body 2 is later sealed with the container.

In the partition member main body 2, the cross-sectional cut along the plane 7a formed by the opening of the partition member main body has a wide flat boat shape when viewed from the planar direction and thin when viewed in the lateral direction. As shown by the inclined line portion of Fig. 1B, as used herein, the "plane 7a formed by the opening of the partition member main body" means a flat surface formed by the opening 7 of the partition member main body. This plane is mainly perpendicular to the wall surface 2a of the partition member main body shown in Fig. 1B. As shown in Fig. 2A, the partition member, when viewed in the front direction, forms a curved shape at the side 8 on the outer surface and becomes narrower as it approaches the end. In the partition member main body 2 of this example, two inclined surfaces 8a are formed at the side 8. By providing such an inclined surface 8a, when heat-sealing the partition member 1 together with the container, the film constituting the container can be prevented from generation of pinholes in the A-shaped portion, and the partition member 1 Membranes made of synthetic resins are preferred for melt sealing without gaps.

At both sides of the partition member main body 2, the protruding strip 9 is preferably provided so as to protrude therefrom towards the outside. 3A and 3B are front and top views, respectively, of the partition member main body 2 provided with the protruding strip 9. As shown in Fig. 3A, the protruding strip 9 is more preferably provided to protrude from the side 8 in a direction perpendicular to the thickness direction of the flat partition member main body 2, and the side 8 on the outer side. And thinner as it progresses from the intersection. By virtue of such a configuration, the film constituting the container is not only prevented from generation of pinholes in the A-shaped portion, but also the film can be strongly melt-sealed in the partition member 1.

The partition member 1 of the present invention is deformed by applying stress thereon to achieve the passage to the partition member 1. When deforming the partition member 1, the membrane of the container forming material is also drawn, resulting in a force yielding to allow the partition member 1 to peel off from the seal of the membrane, but with a strong seal with the protruding strip 9. The container can resist such peel force.

The partition body 4 is held through the thin wall portion 5 at the intersection with the partition member main body 2. The partition body 4 is used for partitioning the hollow part 3 of the partition member main body 2, and the part except the end of the opening of the hollow part 3, that is, near the opening 7 of the partition member main body 2 It is provided in the excluded part. As shown in Figures 1A and 1B and 2A-2D, the partition body 4 is not provided for closing the end of the hollow part 3, but preferably near the center of the hollow part 3 in Figure 2B. In the middle part in the vertical direction of the hollow part 3 shown in FIG.

The partition body 4 is a member for reliably separating the contents from the container before use to prevent deformation of the partition member 1 with the thin wall portion 5 when melt sealing the partition member 1 with a membrane. In this way, the compartment body 4 has the function of resisting deformation of the compartment member 1 in the melt seal. On the other hand, as described in detail below, the partition member 1 of the present invention has a function of rupturing the thin wall portion 5 so as to pass through a plurality of containers and causing bending deformation into a bent shape upon application of force. Also do. Now, the function of the partition body 4, that is, the resistance to deformation of the partition member 1 in the melt seal, ruptures the thin wall 5 in order to pass through the plurality of vessels. It resists the function of introduction to bending deformation into a curved shape when subjected to a force. In other words, as the force of the partition main body 4 that resists deformation of the partition member 1 in the melt seal increases, the passage of the plurality of containers partitioned by the partition member 1 in turn and the rupture of the thin wall portion 5 occur. It becomes more difficult to generate

For the purpose of adjusting the opposite two functions that facilitate the partition body 4 to be sufficiently strong against the deformation of the partition member 1 in the melt seal and at the same time through the plurality of containers, as shown in FIG. 4B, The partition body 4 may be provided so as to be inclined with respect to the plane 7a formed in the opening of the partition member main body when the partition member 1 is viewed from the lateral direction. 4A is a front view of the partition member 1 and FIG. 4B is a side view. Now, in the planar form, the partition body 4 is not parallel to the plane 7a formed by the opening of the partition member main body. By providing the partition body 4 while tilting it, the thin wall portion 5 is easily ruptured and easily made to pass through. The inclination angle L of the partition body 4 shown in Fig. 4C is preferably determined by roughly considering the constituent material of the partition member 1, the thickness of the thin wall portion 5, the size of the partition member 1, and the like. do. For example, this angle is 45 ° to 88 °, preferably 55 ° to 85 °, more preferably 65 ° to 83 °.

As the inclination angle L becomes smaller, the partition body 4 decreases the function of resisting deformation of the partition member 1 in the melt seal, and consequently the partition member 1 in the melt seal is in the same direction when subjected to shear force. Undergoes shear deformation. For example, as shown in Fig. 4B, in the case of the partition member 1 in which the partition body 4 is inclined, the force in the melt seal is applied from both the left and right directions, as shown by the arrows in Fig. 4B. Likewise, the partition member 1 is deformed in the upper right direction and the lower left direction at the same time. The direction in which the deformation occurs is determined by the inclination direction of the partition member 1.

Shear deformation can be suppressed when melt sealing is performed by using a jig and fixing the partition member 1 to increase the wall thickness or to prevent shear deformation at the side of the partition member 1. By suppressing the shear deformation in this way, the function of resisting deformation in the melt seal is such that the inclination angle L is a function of the partition member 1, i.e. introducing bending deformation into a bent shape in the reception of a force and a thin wall portion 5 Can be more reliably maintained after being less than 90 ° without reducing the ability to rupture).

As shown in Fig. 5A. In the partition member 1 of the invention, the partition body 4 can also be arranged at an angle with respect to the plane formed by the opening 7 of the partition member main body when the partition member 1 is viewed from the planar direction. FIG. 5A is a top view of such a partition member 1 and FIG. 5B is a side view. Also in this case, in the planar form, the partition body 4 is not parallel to the plane 7a formed by the opening of the partition member main body. By this arrangement, the two opposite functions described above can be adjusted so that the partition body 4 is strong against deformation of the partition member 1 and at the same time facilitates the passage of the plurality of containers.

Further, the partition body 4 may be provided to be inclined with respect to the plane 7a formed by the opening of the partition member main body when the partition member 1 is viewed from the lateral direction and when viewed from the planar direction.

Although the partition body 4 described above all has a tubular shape, the partition body may be a curved partition body 4a as shown in the plan view of the partition member 1 of FIG. 6A, and the partition member 1 of FIG. 6B. It may be a convexly curved surface-shaped partition body (4b) as shown in the plan view of the) and the shape is not particularly limited. When the partition body 4 has a different shape than the tubular shape, the partition member main body 2 can be more restrained from being subjected to a force in the melt seal.

In the technique of Japanese Unexamined Patent Application, First Publication No. 2001-87350, in the production of a container using a partition member in which a lid body is used as the partition body, the container has a lid portion fixed side, for example, the inner side of the container. It should be made by positioning it always facing, whereas in the present invention the compartment body is provided in the hollow compartment position, so that the positioning of the compartment member to face in a specific direction with respect to the container is not necessary.

The thin wall portion 5 formed at the connection between the partition bodies 4, 4a or 4b is a part which is rupturably given for the partition member 1 by an external deformation operation. The thickness of the thin wall portion is preferably about 0.05 mm to 0.25 mm, more preferably about 0.07 mm to 0.20 mm. If the thickness is smaller than 0.05 mm, not only the formation of the partition member 1 becomes difficult, but also rupture may occur due to the internal pressure and the weight of the medicament in the sterilization apparatus of the container, which is undesirable. On the other hand, if the thickness exceeds 0.25 mm, an excessively large force is undesirably required in the operation of deforming the partition member.

In the partition member 1 of the present invention, as shown in the front view of FIG. 2D, the connection between the partition body 4 and the partition member main body 2 is a thick wall portion 6 in part and the thin wall portion remaining. It can also be configured to be (5). By taking such a configuration, when the partition member main body 2 is bent and deformed, only the thin wall portion 5 is ruptured, but the thick wall portion 6 is not ruptured and the partition body 4 is the partition member main body 2. ) And stay in the hollow part 3 without failure and consequently, after opening the lid, the compartment body 4 does not float as foreign matter inside the container. At the same time, a thick wall 6 is provided at the connection which does not close the hollow part 3 again after rupture of the thin wall part 5.

Figure 7 shows another example of a partition member according to the present invention. In the example of Fig. 1, members having the same reference numerals represent the same members, and description thereof is omitted here.

The partition member 1 of FIG. 7A has two support members 10. At both ends of each support member 10, a thin strip 11 is provided. FIG. 7A is a perspective view of the partition member 1 showing a state in which the supporting member 10 is inserted into the hollow portion 3, and FIG. 7B shows a state in which the supporting member 10 is inserted into the hollow portion 3. It is a top view of the partition member 1 shown.

In the hollow part 3 of the partition member main body 2 of the present invention, at least one preferably one or two support members 10 are provided. By the supporting member 10, the partition member main body 2 is reliably prevented from deformation when melt-sealing the container and the partition member main body 2 and the thin wall 5 when the excessive force is applied to the melt seal. It can be prevented from deformation or breakage. For example, this is the support member shown in the enlarged view of FIG.

As shown in Fig. 9A, the supporting member 10 is disposed so as to lie along the vertical (width) direction of the opening 7 when the partition member main body 2 is viewed from the front. The support member 10, shown enlarged in Fig. 8A, includes a connecting member 10b and a plurality of ribs 10a extending in the longitudinal (length) direction of the dog for connecting to the central portion of the rib 10a, respectively.

Such a supporting member 10 is inserted into the hollow part 3 in the opening 7 portion of the partition member main body 2 and as a result, when the force is applied to the partition member 1 as a whole, the rib 10a is The hollow portion 3 can be prevented from deformation of the shape.

By providing the support member 10 of the hollow part 3, the partition member 1 can be prevented from twisting of the outer surface due to the pressure in the heat seal and generation of gaps or spots on the heat seal surface can be suppressed. In order to be able to do so, the shape of the hollow part 3 can be maintained at the time of heat sealing the outer surface of the container and the partition member 1. As shown in FIG. 8A, the rib 10a may be provided at the same upper and lower portions relative to the connecting member 10b, or as shown in FIG. 8B, the rib 10a may be connected to the connecting member 10b. It can be provided as an alternative to.

In addition, as shown in FIG. 7B, when the partition member 1 is observed, the length is not particularly limited in the vertical direction (thickness) of the support member 10, but the vertical direction ( Height) of 1/4 or less of the length.

The support member 10 is preferably coupled to the partition member main body 2. By joining it, the support member 10 and the partition member main body 2 are integrated, and the partition member main body 2 can be more reliably prevented from deformation in the operation of the melt seal on the container and the partition member 1. The support member 10 does not fall away from the partition member 1 to ensure that it is. The joining can be performed, for example, by a method of providing a catch between the partition member main body 2 and the support member 10, but in order to make the joining more secure because the partition member 1 is deformed, It is preferably integrated by melt sealing. More specifically, for example, as shown in FIG. 8C, a thin strip 11 that is coupled to the partition member main body 2 and is melt sealable is suitably provided at one end, preferably at both ends, of the support member 10. do. By virtue of this configuration, the end face 9a of the protruding strip or the end face 8b of the side shown in Fig. 3A can be hermetically sealed to the thin strip 11 provided at one end or both ends of the support member 10. . In this way, by melt-sealing the support member 10 to the partition member main body 2 through the thin strip 11, the support member 10 can be prevented from falling off the partition member main body 2. .

Also, as shown in Fig. 8C, in order to integrate the support member 10 to the partition member main body 2 and to melt-tighten it more tightly, a thin strip 11 of ribs is provided at the end of the support member 10. Further preferably at the end of the rib 10a is also provided.

Not only does the support member 10 achieve reinforcement so that the deformation of the partition member main body 2 in the melt seal can be prevented by receiving the force F in the orthogonal direction shown in Fig. 9A, but also in Fig. 9B. It is required that there should not be excessive resistance to bending, such as the bend shown. In this sense, if the resistance is excessive for bending, for example bending, the force for bending can be reduced by reducing the number of ribs 10a or alternatively providing the ribs, as shown in FIG. 8B. .

When two support members 10 are provided in the hollow part 3 of the partition member main body 2 as shown in Fig. 7A, the partition body 4, which has fallen as a result of the rupture of the thin wall part 5, It is captured in the hollow part 3 formed by the two support members 10 and the partition member main body 2 and does not flow into the bag portion of the container so that the container can be prevented from inclining to contain foreign matter.

In the specific example described above, the cross section cut along the plane 7a formed by the opening of the partition member main body has a boat shape, but as another example of the partition member, the cross section may have a rhombus shape, an ellipse shape or a circular shape. .

In the partition member 1 of the present invention, when stress is applied at right angles to the direction of passage of the partition member 1, the thin wall portion 5 is ruptured so as to communicate with the plurality of containers.

In particular, by applying the force F1 in the same direction at the end in the cross direction on both sides of the partition member 1 toward the thickness direction of the container as shown in FIG. By applying the force F2 to the central portion in the cross direction of (1), when a force is applied to bend the partition member 1 in a bent shape, the different stresses are respectively divided against the external force due to the difference in stress. Generated from the main body 2 and the partition body 4, the thin wall portion 5 of the connection between the partition body 4 and the partition member main body 2 can be ruptured. That is, the partition member 1 in which the thin wall part 5 is ruptured by the bending of the partition member 1 is preferable.

The cross-sectional shape of this bent partition member 1 is not particularly limited, but since the container using it in the cross direction is required to be flat, the ratio of the partition member 1 to the partition member 1 shown in Fig. 2A ( Longitudinal length / vertical length) is preferably 3 or more. In addition, since the force is mutually applied in almost all cases, the length in the longitudinal direction is preferably about 3 cm to 20 cm. As used herein, the longitudinal direction represents the cross direction of the container in the container of FIG. 11, and the vertical direction represents the thickness direction of the container in the container of FIG.

In the partition member 1 of the present invention, when the partition body 4 is tubular and inclined with respect to the plane 7a formed by the opening of the partition member main body, the partition member 1 is used to support the support member 10. Having a cross-sectional shape that can be allowed to bend, and applying a force to the partition member 1 in the same direction as that in the melt sealing of the container (see Fig. 9A), while at the same time the partition body 4 The possibility of easy rupture of the thin wall portion 5 by the advantage of the inclination of can be suppressed due to the deformation preventing activity of the partition member main body 2 by the advantage of the supporting member 10, and at the same time the thin wall portion by bending The force required to rupture (5) hardly increases. Therefore, this is a very good partition member 1 which is weak against the bending shown in FIG. 9B and very strong against the compression shown in FIG. 9A.

In addition, a partition member 1 in the form opposite to the partition member that allows passage by bending can be constructed, that is, the partition member 1 is bent as shown in Fig. 9B, and the By applying a force in a direction opposite to F1 and F2, the partition member main body 2 is deformed into the planar shape shown in Fig. 9A and thereby through the thin wall portion 5 in a state where the thin wall portion 5 is ruptured. The partition body 4 is connected to the partition member main body 2. In the partition member 1, since the bent state is deformed into a planar state, it is clear at which angle the deformation is made. Thus, for example, an excessively large deformation of the partition member 1 can be easily suppressed by applying an external force near the bend of the plane.

The partition member 1 of the present invention can be manufactured by injection molding. In this particular example, as shown in Fig. 7C, the partition member comprising the support member 10 of the present invention is preferably molded as a completely single member. In the example of FIG. 7C, one end of the supporting member 10 on the side where the thin strip 11 is not provided is connected to one end of the opening 12 of the partition member main body 2 via the connecting portion 13. This connecting part 13 can be bent and the supporting member 10 can be inserted into the hollow part 3 in the opening 7 of the partition member main body. The connecting portion 13 is thinly walled to the extent that it can be bent, and by integrating the intersection of the melt seal and the supporting member 10 and the partition member main body 2, the connecting portion 13 is a thin strip 11. Used similarly to

The shape of the support member accommodated in the partition member main body may be the same as that shown for example in Figs. 13A and 13B. The supporting member 31 shown in Fig. 13A is formed of the opening 33 of the partition member main body 32 constituting the partition member 30 for connecting the plurality of ribs 31a and the central portion of the ribs 31a. And a connecting member 31b extending in the right and left (length) directions. At the center of the partition member main body 32, a configuration is made in which the connecting member 31b is divided into two parts.

When the container is made to pass through, since the support member 31 is configured such that the connecting member 10b connecting the rib 31a is divided into two parts at the center portion of the partition member main body 32, Fig. 13B. As shown in FIG. 6, the force F1 in the same direction in the thickness direction of the container is applied to the widthwise ends on both sides of the partition member 30, and the force F2 in the reverse direction of the widthwise end is applied to the partition member 30. ) Is applied simultaneously to the center portion in the width direction. The external force of bending the partition member 30 in a bent shape ends small compared to the support member 10 previously shown in FIG. Since the partition member 30 is easily bent, the container is made to pass through and it is possible to remarkably improve the handling force.

The shape of the support member accommodated in the partition member main body may be as shown for example in Figs. 14A and 14B. For example, the support member 41 shown in Fig. 14A is an opening of the partition member main body 42 constituting the partition member 40 for connecting the plurality of ribs 41a and the central portion of the ribs 41a. And a connecting member 41b extending in the right and left (length) directions of (43). An inclined portion 41c tapering the thickness of the rib 41a is formed on the rib 41a side facing the main body 45 divided on the side opposite the opening 43. Both ends of the support member 41 are connected to the partition member main body 42.

By forming the inclined portion 41c in the rib body 41a side partition body 45, if the partition member 40 is bent as shown in Fig. 14B to allow the container to pass through, then the support member 41 is The state of being separated from the partition member main body 42 on the outside by the action of the inclined portion 41c is achieved by means of the partition body 45 separating from the partition member main body 42. By means of this configuration, the small external force applied to the partition member 40 also makes the partition member 40 easily bent, and the container is made to pass through. Therefore, it is possible to remarkably improve handling.

The shape of the support member accommodated in the partition member main body may be the same as that shown in Figs. 15A and 15B, for example. The supporting member 51 shown in Fig. 15A is accommodated in the partition member main body 52 by connecting with the plurality of ribs 51a at both ends of the inclined portion and forming a spring-like structure that extends continuously in a substantially triangular cross section. As shown in Fig. 15B, the force F1 is applied in the same direction as the thickness direction of the container from the thickness direction on both sides of the partition member 50 to the end, and the width in the center portion in the width direction of the partition member 50. By simultaneously applying a force F2 to the opposite end of the direction, such a support member 51 causes the partition member 50 to bend. As a result, the angle of the rib 51a changes, increases similarly to the spring, the partition member 50 is easily bent by a small external force, and the container is made to pass through. Therefore, it is possible to greatly improve the handling power.

The shape of the support member accommodated in the partition member main body may be, for example, the same as that shown in Figs. 16A to 16C. The support member 61 shown in Fig. 16A such that a plurality of ribs 61a are formed on both sides of the connecting member 61b extending in the right and left (length) directions of the opening 63 of the partition member main body 62. ) Is configured. As shown in Fig. 16C, the structure at the connecting portion between the connecting member 61b and the rib 61a has a narrow portion 61c in which the width (right and left directions in Fig. 16C) of the rib 61a is narrowed. When made and stress is applied, the rib 61a easily falls toward the connecting member 61b at this narrow portion 61c.

As shown in Fig. 16B, a narrow portion 61c is formed at the connecting portion between the rib 61a and the connecting portion 61b, and in the same direction as the thickness direction of the container at the end portions in the width direction on both sides of the partition member 60. By applying the force F1 and simultaneously applying the force F2 to the center portion in the width direction of the partition member 60 in the reverse direction in the width direction, the partition member 60 is then made to bend. As a result, the rib 61a easily falls toward the connecting member 61b at the narrow portion 61c, and the partition member 60 is easily bent by a small external force, and the container is made to pass through. Therefore, it is possible to greatly improve the handling power. The width of the narrow portion 61c may also be set to be about 10% to 60% of the width of the normal portion of the rib 61a.

The container of the present invention is obtained by incorporating a partition member having a bag-shaped flexible container formed of a membrane or sheet, using at least one partition member of the present invention. 10A and 10B and 11 illustrate this example. In this example, another communicating means, like a weak seal, is used jointly.

Examples of constituent materials of the flexible container include polyolefins (for example, polyethylene, polypropylene, ethylene-propylene copolymers and mixtures of polypropylene and polyethylene or polybutene), partially Cross-linked products, ethylene-vinyl acetate copolymers (EVA), polyesters [eg, polyethylene terephthalein, polyethylene naphthalene, polybutylene terephthalate] and soft Soft vinyl chloride. Single or multilayer films or sheets comprising such materials and having a thickness of 50 μm to 400 μm are shaped and used in the form of bags. In such films or sheets, a barrier layer with oxygen and / or moisture barrier properties may be provided depending on the contents. Examples of barrier layers include ethylene-vinyl alcohol copolymers, polyamides, polyvinylidene chloride, aluminum foil, silicon oxide and water vapor deposited resin films, aluminum oxide and water And a resin film deposited with aluminum and a water vapor deposition.

The bag body used for forming the flexible container shown in FIGS. 10A and 10B and 11 is obtained by heat sealing the peripheral edges of two sheets of the film obtained by a T-die mold or the like, but the present invention is not limited thereto. And tubular membranes obtained by expansion molding or the like can also be used.

In order to integrate the flexible container and the partition member, a method using an adhesive or by heat sealing may be used, but a method by heat sealing is preferable because there is no fear of mixing into the contents of the container. During the performance of the heat sealing, the surface of the partition member is preferably preheated by heating with the use of radiant heat or metal molds. The heat sealing is generally performed by a method using a metal mold that matches the outer shape of the partition member, but can be performed by an impulse sealing method, a high frequency sealing method, an ultrasonic sealing method, or the like.

In addition, as shown in Fig. 10A, since the communication with the partition member 1 and the portion where the contents existing after the passage are reduced are easy, the V-shaped from both sides with the vertices transferred to the partition member 1 are easy. Containers with cuts are also preferred. As shown in Fig. 10B, it is also possible to arrange the partition member 1 at the corners and to provide cutting only on one side.

Although injection containers with multiple chambers using seals obtained by detachably heat sealing the synthetic resin for the compartments are known, the internal pressure of the contents in this container increases the application of external forces and forces in the direction of peeling off weak seals. Cause careful action and therefore require careful handling at all stages until immediately before use. Containers using the partition member 1 of the invention for the compartment have a very low likelihood of improperly communicating through the compartment prior to use. In addition, as shown in Fig. 9B, when the partition member used for the container has the support member 10 and is subjected to bending deformation to generate a tear, stress is applied to three positions at both ends and the center simultaneously in a specific direction. Communication occurs through the partition member only when the very limited conditions to be added are met, so that communication by external forces beyond control does not occur.

When the partition member of the present invention is used to manufacture a container, the plurality of containers can be melt sealed without a gap in the partition member and at the same time, the processing can be simplified. In addition, in the use of the container using the partition member of the present invention, the thin wall portion is easily ruptured to allow it to pass through the plurality of containers, and the material which is regarded as a foreign matter after the rupture does not come up. Therefore, a container using the partition member of the present invention is useful because it can be used in the food or medical field.

The container of the present invention is useful because it can reliably separate contents such as food or medicament contained in a plurality of chambers before use, can quickly mix the contents immediately before use, and can be used as a container in the food or medical field.
