FIG. 5 is an exploded perspective view showing an example of the structure and positional relationship between the spout member and the bag body.

  As shown in FIG. 1, the multi-chamber packaging bag 100 of the present invention is composed of at least the tubular spout member 1 of the present invention and a bag body 4 and closes the spout member 1 as necessary. A closing member 2 is provided. A combination of the spout member 1 and the closing member 2 is a spout unit 3.

  As shown in FIG. 2, the bag body 4 is internally partitioned by a plurality of small chambers 10 </ b> X and 10 </ b> Y that are arranged in parallel in the front-rear direction of the bag. Specifically, the bag body 4 is disposed between the pair of opposed plane portions 5 and 5 constituting the front side and the back side of the bag, and between the pair of plane portions 5 and 5, substantially parallel to the plane portion, It has the partition part 6 which divides the inside 10 of the bag main body 4 into a plurality of small chambers 10X and 10Y. The pair of flat portions 5 and 5 and the partitioning portion 6 constituting the bag body 4 are sealed by overlapping their edge portions (upper end sealing portion 7, lower end sealing portion 8, side end sealing). The small chambers 10X and 10Y are spaces independent of each other. Each member constituting the bag body 4 is formed of a flexible film and can be folded or folded.

The spout member 1 functions as a spout for the contents filled in the bag body 4 and is also used as a filling port for filling the contents in the bag body 4 in some cases.
In FIG. 1, the spout member 1 has a screw portion 16 provided on the outer peripheral surface of the spout member 1 and a screw portion (not shown) provided on the inner peripheral surface of the cap that is the closing member 2. By being joined, it is closed by the closing member 2.

As shown in FIGS. 1 and 3, the spout member 1 has a communication passage 11 that communicates the outside of the bag body 4 with the inside 10.
The communication path 11 has an external port 12 connected to the outside of the bag body 4 at one end, and an internal port 13 connected to the interior 10 of the bag body 4 at the other end. The spout member 1 has a joint portion 14 that joins the inner surface of the bag body 4.

As shown in FIGS. 3 and 4, the communication path 11 is provided substantially parallel to the communication direction of the communication path 11 and from the height in the vicinity of the external port 12 to the height of the lower end portion 14 b of the joint portion 14. The partition wall 15 is divided into two small passages 11X and 11Y. The two small passages 11X and 11Y are respectively independent passages that communicate the inside and the outside of the bag body 4, and the small passage 11X communicates the small chamber 10X of the bag body 4 and the outside of the bag body 4, The small passage 11Y communicates the small chamber 11Y of the bag body 4 with the outside of the bag body 4.

Not shown).

  The spout member 1 has a slit 17 that is cleaved from an end of the partition wall 15 on the inner side of the bag body 4, that is, from a lower end edge of the partition wall 15. The slit 17 is split from the partition wall 15 to the joint 14 (see FIGS. 3 (3B) and (3D) and FIGS. 4 (4A) and (4B)). The slit 17 is cleaved so as to divide the partition wall 15 substantially in parallel with the surface direction (see FIGS. 3 (3D) and 4 (4A), (4B)), and the upper end 14a of the joint 14 is formed. The height has been reached (see FIG. 3 (3B) and FIG. 4 (4A)).

  An edge 6 t of a flexible film constituting the partition 6 of the bag body 4 is inserted into the slit 17 in parallel with the partition wall 15. Thereby, the partition wall 15 that defines the communication passage 11 of the spout member 1 and the partition portion 6 that defines the interior 10 of the bag body 4 are joined, and the small passage 11X of the spout member 1 and the small chamber 10X of the bag body 4 are joined. The small passage 11Y of the spout member 1 and the small chamber 10Y of the bag body 4 are communicated with each other as independent spaces.

The spout member 1 is joined to the inner surface of the bag body 4 on the outer peripheral surface of the joint portion 14 and attached to the bag body 4. Specifically, as shown in FIGS. 1 and 5, the spout member 1 is sandwiched between a pair of flat portions 5 and 5, and the edge portions 5 t and 5 t of the pair of flat portions 5 and 5 The outer peripheral surface of the joint portion 14 and the inner surfaces of the flat portions 5 and 5 are joined.
At this time, as shown in FIGS. 4 and 5, the spout member 1 is aligned so that the surface direction of the partition wall 15 is substantially parallel to the pair of flat portions 5 and 5. And the edge part 6t of the partition part 6 is inserted in the slit 17, and the partition 15 and the partition part 6 are joined.
As a result, as shown in FIG. 1, in the bag body 4, the edge 6t of the partition 6 is overlapped and sealed between the edges 5t, 5t of the pair of flat portions 5, 5. The spout member 1 is fixed to the portion 7.

  As described above, the spout member according to the present invention includes a partition that defines the communication path of the spout member, and a bag body by inserting a flexible film into a slit formed on the lower end side of the partition. The partition part which divides an inside is joined, and each small channel | path of a spout member and each small chamber in a bag main body are each connected. Therefore, according to the present invention, the contents filled in the small chambers in the bag body can be taken out to the outside of the bag body through the spout member in a state where they are separated from each other without being mixed. Become.

Hereinafter, the spout member of the present invention and each component of the multi-chamber packaging bag including the same will be described in more detail.
First, the spout member will be described.
The shape of the spout member is not particularly limited as long as it includes at least a partition having a basic structure as described above, that is, a communication path, an external port, an internal port, a joint, and a slit. For example, as in the embodiment shown in FIG. 1, a spout member, a multi-chamber packaging bag to which the spout member is attached, or a content filling body in which the multi-chamber packaging bag is filled with a content, A support flange 18 for suspending may be provided. Moreover, you may provide the alignment rib (not shown) for aligning the spout member lifted with the support flange. Moreover, it does not need to have the thread part for screwing together with the closure member as shown in FIG. 1, and it may be simply cylindrical.

  The closing member that covers the outer opening of the spout member and closes the spout member is not particularly limited as long as the sealing inside the bag body to which the spout member (pouring unit) is attached can be secured. For example, in addition to those having a screw-type cap structure as shown in FIG. 1, the lid is connected to a spout member and has a structure that can be opened and closed in an inseparable state like a door, and is fitted into the external port of the spout member. Those having a stopper structure such as rubber or cork may also be used. The closing member has a structure in which, when taking out the contents filled in the bag body from the spout member, the structure in which one or more small passages to be opened can be selected in addition to a structure that opens the entire outer surface of the spout member. You may have. Furthermore, an inner seal member may be used in order to improve the sealing performance in the bag body. Moreover, the tampering prevention function which prevents unauthorized opening may be provided to the closing member.

As shown in FIG. 3 (3D) and FIG. 5, the joint portion 14 of the spout member 1 has a pair of flanges 14f projecting on the left and right sides in the surface direction substantially parallel to the partition wall 15 on the outer peripheral surface thereof. Preferably it is. This is because, by having such a flange 14f, it is possible to secure a bonding area with the flat portions 5 and 5 by the flange surface. Furthermore, due to the shape of the flange surface of the flange 14f, the adhesion between the inner surfaces of the flat portions 5 and 5 and the outer peripheral surface of the bonded portion 14 in the bonding step between the flat portions 5 and 5 and the bonded portion 14 is increased. This is because the bondability can be improved.
The specific shape of the flange is not particularly limited, and may be appropriately designed according to the structure of the spout member, the structure of the bag body to which the spout member is attached, and the like.

  When the joint portion has a flange, the partition wall may be provided at a position that is linearly connected to the left and right flanges, or may be provided at a position that is not linearly connected. For example, as shown in FIG. 3 (3D), when the flange is provided at the center position in the front-rear direction of the spout member, and the partition 15 is provided so as to divide the cross section of the communication passage into equal parts, the partition 15 As shown in FIG. 6, the flange is provided at the center position in the front-rear direction of the spout member, and the partition wall 15 has a non-cross section of the communication passage. When provided so as to be divided equally, the partition wall 15 is provided at a position where it is not linearly connected to the left and right flanges 14f, 14f.

Moreover, when a junction part has the above flanges, a slit is cleaved from the front-end | tip part or flange surface of a flange. For example, as shown in FIG. 3 (3D), when the partition wall 15 is provided so as to equally divide the cross section of the communication path, the slit 17 is usually cleaved from the tip portion 14ft of the flange 14f. Further, as shown in FIG. 6, when the partition wall 15 is provided so as to divide the cross section of the communication path into non-equal parts, the slit 17 is cleaved from the flange surface at a position corresponding to the partition wall 15 of the flange 14 f.
In addition, when the flange is provided so as to be shifted from the center position in the front-rear direction of the spout member, the shape is not limited to this.

  The spout member is not limited to a form having one partition that divides the communication path into small passages, that is, a form that divides the communication path into two small passages, and has two or more partition walls and three communication paths. The form divided into the above small passages may be sufficient. For example, as shown in FIG. 7, the communication path may be divided into three small paths 11X, 11Y, and 11Z by two partition walls 15 and 15.

  The flexible film, which is the partition wall and the partition part of the bag body, is joined by inserting the flexible film into the slit. And in order to ensure the independence between the small passages of the spout member communicating with the small chamber, it is preferable that the partition wall and the partition portion are bonded in the slit of the partition wall. The method for bonding is not particularly limited. For example, a method using an adhesive or a heat sealing method may be mentioned. However, since the lower end edge of the partition wall is a position in contact with the contents, a heat sealing method is preferable to a method using an adhesive.

  Further, if the partition wall is provided at least from a position higher than the upper end of the joining portion to a position lower than the upper end, by inserting a flexible film constituting the partition portion of the bag body into the slit, It can be joined to the flexible film. In addition, if the upper end of the partition wall has a height at which each small passage can be sealed at the external port by the closing member, independence between the small passages can be ensured. Therefore, the partition wall 15 does not necessarily have to be provided from the height in the vicinity of the external port 12 to the height of the lower end portion 14b of the joint portion 14 as shown in FIG. However, the partition wall 15 having a height as shown in FIG. 4 has advantages in terms of sealing reliability by the closing member of each small passage, simplification of the structure of the closing member, and the like.

Furthermore, as for the partition 15, as shown in FIGS. 8-10, it is preferable that the edge (lower end) of the inner side of a bag main body protrudes from the internal port 13. As shown in FIG. When the lower end of the partition wall 15 protrudes from the inner port 13 in this way, the adhesion between the partition wall 15 and the flexible film that is the partition portion 6 inserted into the slit 17 of the partition wall 15 is bonded to the spout member. This is because it is difficult to be obstructed by the portion 14 and the communication passage 10 and the like, and it becomes easy.
For example, when the partition 15 and the flexible film which is the partition portion 6 inserted in the slit 17 of the partition 15 are bonded by heat sealing, the partition is inserted in the state where the flexible film is inserted in the slit 17. The partition wall 15 and the flexible film can be bonded together by heating and pressurizing both surfaces of 15. That is, when the lower end of the partition wall 15 protrudes from the lower end of the inner port 13, it becomes easy to apply heat seal bars to both surfaces of the lower end of the protruded partition wall 15 from the outside, and the partition wall 15 with the flexible film inserted is formed. Heating and pressurization are easy, and adhesion between the partition wall 15 and the flexible film becomes easy.

  The structure of the slit is that if a flexible film that is a partition part of the bag body, that is, a flexible film that is wider than the diameter of the spout member at the joint part can be inserted substantially parallel to the partition wall, There is no particular limitation on the structure. For example, as shown in FIG. 3 (3B) and FIG. 4 (4A), the slit does not have to reach the height of the upper end 14a of the joint portion 14, and is close to the upper end 14a (for example, slightly below the upper end 14a). The structure reaching the height of the side) may be used. The upper end of the slit may penetrate the upper end surface of the partition wall.

As shown in FIG. 4, the slit extends substantially parallel to the entrance to one or both of the inner surfaces facing each other at or near the entrance as well as a simple slit structure into which the flexible film can be inserted (see FIG. 11). ) A structure in which a protrusion 17a is provided and the gap between the flexible film inserted into the slit and the partition wall can be sealed by a force sandwiching the tip of the protrusion 17a. 11 is a partially enlarged sectional view (11A) in the vicinity of the spout member 1, an enlarged sectional view (11B) of the lower end of the partition wall 15 of the spout member 1, and an enlarged perspective view of the inner surface of the slit 17 of the partition member 15. It is a figure (11C).
As shown in FIG. 11, a slit provided with a protrusion 17a extending substantially parallel to the inlet on one or both of the inner surfaces facing each other at or near the inlet has the following merits. As an example. That is, it is possible to improve the fixing property of the flexible film as the partition portion and the sealing performance between each small chamber and each small passage. In addition, the provision of the protrusions as described above can prevent the contents from entering the slit, and there is an advantage that the sanitary aspect of the packaging bag is improved. Depending on the structure of the protrusions, even when the contents filled in the bag body are highly permeable to liquids, the partition provided with the protrusions and the flexible film (partition part) can be heat-sealed, adhesive, etc. Even if it is not used and adhered, it is possible to prevent the contents from entering the slit.

  The specific structure of the protrusion provided in the slit is not particularly limited. For example, in the embodiment shown in FIG. 11, the protrusions 17a and 17a are provided on both inner surfaces facing each other at the entrance of the slit, but the protrusion may be provided only on one of the inner surfaces facing each other. However, in order to surely obtain the effect of the protrusions, it is preferable that the protrusions are disposed so as to abut against each other on both the entrance of the slit or the inner surfaces facing each other in the vicinity thereof. Further, the cross-sectional shape of the protrusion is not particularly limited.

  The material forming the spout member is not particularly limited as long as it can be bonded to the flexible film constituting the bag body at the bonding portion and can be fixed to the bag body. However, as described above, when the spout member and the flexible film constituting the bag body are joined by heat sealing, the adhesive member is usually adhesive with the flexible film, and the heat sealing is performed. It must be formed of a material that is resistant to heating in the process. Therefore, it is typically formed of a plastic material that is the same material as the inner layer having heat sealability, which is the innermost layer of the flexible film described later. As such a plastic material, for example, polyolefin such as polypropylene and polyethylene can be used.

A method for attaching the spout member to the bag body by joining the outer peripheral surface of the joint portion of the spout member to the inner surfaces of the pair of flat portions constituting the bag body is not particularly limited. Examples thereof include a method using an adhesive and a heat seal method.
As a specific method of the heat sealing method, for example, the surface material of the joint portion of the spout member and the material of the innermost surface layer of the flexible film constituting the flat portion of the bag body are the same in heat sealing properties. A method of heating the joint portion and the pair of plane portions in the state where the spout member is sandwiched between the pair of plane portions and the joint portion is aligned with the edge portions of the pair of plane portions is used as the material. It is done. The partition part arrange | positioned between a pair of plane parts is inserted in the slit of a spout member, and the partition and partition part of a spout member are joined. As described above, the partition portion and the partition wall may be bonded by an adhesive, heat sealing, or the like as necessary.

  In the multi-chamber packaging bag of the present invention, the attachment position of the spout member is not particularly limited. For example, as shown in FIG. 1, in addition to a form attached to the center of the upper end portion of the bag main body, it may be a corner portion of the upper end portion of the bag main body, or may be a lower end portion or a side edge portion of the bag main body.

Next, the multi-chamber packaging bag will be described.
The multi-chamber packaging bag to which the spout member of the present invention is attached has a pair of flat portions as described above, a partition portion, and a bag main body having a plurality of independent small chambers that are partitioned in the front-rear direction. If it does, the structure will not be specifically limited.
The multi-compartment packaging bag has a sealed portion in which the edge portions of the partition portion are overlapped and sealed between the edge portions of the pair of plane portions. In the sealing part, the edge part of the flexible film of each member which comprises a bag main body is joined, and the inside of a bag main body and a small chamber are formed. In order to seal the edge part between each member, the method of joining the opposing surfaces of the overlapped flexible film is not particularly limited. For example, the relative of the flexible film using an adhesive is used. For example, a method of adhering surfaces to be bonded to each other, a method of bonding opposite surfaces of a flexible film with the same material, and heat sealing.
Here, the “heat-sealable homogenous material” refers to a material that has the property of being thermally fused by heating and capable of being joined.

For example, in the multi-chamber packaging bag 100 shown in FIG. 1, as shown in FIG. 5, the bag body 4 includes a pair of opposed flat portions 5 and 5 that constitute the front and rear sides of the bag, two ridges, and a valley. A gusset-shaped bottom portion 19 having a single portion and a partition portion 6 disposed between the pair of plane portions 5 and 5 substantially in parallel with the plane portion and sandwiched between valleys 19a of the bottom portion 19 Has been.
As shown in FIG. 12, the lower end portion of the partition portion 6 is sandwiched between the valley portions 19a of the bottom portion 19 and is fixed between the flexible films constituting the valley portions 19a of the bottom portion 19 (sealing portion). 20). The pair of flat portions 5 and 5 sandwich the partition 6 and the bottom portion 19 from the front and the rear, and are joined to the bottom portion 19 at the lower end portion of the flat portion and the lower end portion of the bottom portion (sealing portion 8). The pair of flat portions 5 and 5 are joined to the side edges of the partition portion 6 sandwiched between the flat portions 5 and 5 at the side edges (sealing portion 9). The side edge portion of the bottom portion 19 folded in the sealing portion 9 is also joined to the partition portion 6 and the side edge portion of the flat portion. Furthermore, the upper end part of the partition part 6 and the upper end part of the plane parts 5 and 5 are joined (sealing part 7).
In this way, the bag body is made by overlapping and joining the edge portions of the flexible film constituting the bag body. In addition, the joining order of the flexible film which comprises each member is not limited to the said order.

The specific structure of the bag body is not particularly limited. For example, the bag body described above is an example of a self-supporting multi-chamber packaging bag having a gusset structure at the bottom, but may be, for example, a multi-chamber packaging bag having a gusset structure at the side, Further, it may be a flat bag type multi-chamber packaging bag consisting of only a pair of flat portions and a partition portion.
Furthermore, the number of small chambers arranged in the front-rear direction in the bag body is not limited to two, and a structure in which three or more small chambers are provided by using two or more partition portions.

  The flexible film constituting the packaging bag is not particularly limited as long as it is a flexible film that is generally used for the manufacture of bags. For example, a single layer film may be used, and a base material layer as an outermost layer, It may be a laminated film composed of multiple layers such as an intermediate layer and an inner surface layer as the innermost layer.

  The base material layer is preferably a layer that forms the outermost layer of the bag and has functions such as printability, pinhole resistance, and impact resistance. Examples of the material for the base material layer include uniaxial or biaxially stretched films such as polyethylene terephthalate, polypropylene, polyamide, and ethylene vinyl alcohol copolymer, and laminated films using these stretched films.

  When these stretched films or laminated films are required to have oxygen barrier properties and water vapor barrier properties as a bag application, examples of the material of the base material layer include metals such as aluminum, aluminum oxide, and oxidation. A vapor-deposited film in which an inorganic oxide such as silicon is vapor-deposited; a coat film in which polyvinylidene chloride, polyacrylic acid-based resin, or the like is coated (barrier coat); Moreover, paper, cellophane, etc. can also be used.

  The intermediate layer is preferably a layer having functions such as oxygen barrier properties, water vapor barrier properties, and tearability. As the material of the intermediate layer, when oxygen barrier properties and water vapor barrier properties are required for the use of the bag, for example, metal foil such as aluminum foil; metal such as aluminum, aluminum oxide, and silicon oxide A film on which an inorganic oxide such as a film is deposited; a film on which a polyvinylidene chloride, a polyacrylic acid resin, or the like is coated (barrier coat);

  The inner surface layer is preferably a layer that forms the innermost layer of the bag and can be heat sealed. As the material of the inner surface layer, for example, an unstretched film made of low-density polyethylene, high-density polyethylene, linear low-density polyethylene, polypropylene, ethylene vinyl acetate copolymer, ionomer resin, or the like, or these resins are extruded in layers. Things.

  The method of laminating these layers to form a laminated film is not particularly limited as long as it is a laminating method generally used for forming a laminated film. For example, the laminated film is formed by dry laminating using an adhesive. It may be a method, or a method of forming a laminated film by an extrusion laminating method using a thermoadhesive resin. Moreover, the method of forming a laminated film by the other lamination method may be sufficient.

  The order of attaching the bag body to the bag body and the spout member to the bag body is not particularly limited. For example, the spout member may be attached to the bag body in a state where the flexible film constituting the bag body has been joined (sealed), except for the attachment portion of the spout member, The spout member may be attached at the same time as sealing the edge of the flat part and partition part to be attached, or after joining the pair of flat parts and spout member constituting the bag main body, Bag making may be performed. Moreover, about joining of a spout member, a plane part, and a partition part, after bonding the flexible film and spout member which comprise a partition part, for example, joining a plane part to this spout member Also good.

  The multi-chamber packaging bag of the present invention is not particularly limited in the contents to be filled, but is suitable for filling a plurality of kinds of contents to be used simultaneously without mixing. In addition, the multi-chamber packaging bag of the present invention is preferably mixed immediately before use, because if it is preliminarily mixed in one bag, its state will change over time or the quality will deteriorate over time. It is also suitable for filling multiple types of contents.

Specifically, as a combination of contents to be used at the same time without mixing, for example, mustard and ketchup, margarine and jam, etc., a combination of fluids, and a combination of solids and fluids such as sugar and cream Is mentioned. Moreover, it can also be filled with the individually packaged contents.
Moreover, as what is preferably mixed immediately before use, for example, soy milk and a coagulant, medical infusion to be mixed, fluid combinations, dressing and sesame, dressing and powdered cheese, water and tea powder, A combination of a fluid and solid matter such as

  The content filling body in which the multi-chamber packaging bag of the present invention is filled is filled with different types of contents in each small chamber so that the contents are separated from each other without being mixed with each other. Can be encapsulated. Accordingly, the content filling material of the present invention, as exemplified above, is a different type of content that changes in its state over time when pre-blended in one bag. Alternatively, even different types of contents that cause quality degradation can be stored without causing state changes or quality degradation.
