FIG. 1 is a perspective view showing a refill container 1 which is an example of a refill container of the present invention. The refill container 1 is a refill container for refilling the refill container with contents in a state where the refill container 1 is connected to an injection member having a shape in which a part in the circumferential direction is cut off.
As shown in FIG. 1, the refill container 1 includes a storage portion 10 in which contents are stored, and a pouring member 12 that pours out the contents in the storage portion 10. When the refill container 1 is used, the contents in the storage portion 10 are poured from the pouring member 12 into the refill container in a state where the pouring member 12 is connected to the injection member of the refill container.

The accommodating part 10 should just be what can accommodate the content, for example, the pouch etc. which made the resin sheet the bag shape by the heat seal are mentioned.
Examples of the material for the resin sheet include low-density polyethylene, linear low-density polyethylene, high-density polyethylene, polypropylene, polyethylene terephthalate, nylon, ethylene-vinyl acetate copolymer, or a saponified product thereof.
The resin sheet may be an unstretched sheet, a uniaxially stretched sheet, or a biaxially stretched sheet. When the material is nylon or polyethylene terephthalate, a biaxially stretched resin sheet is preferable because mechanical strength is improved.
The resin sheet may be a laminate. When the resin sheet is a laminate, it is preferable that the innermost layer (innermost layer) is polyethylene (low density polyethylene, linear low density polyethylene, high density polyethylene) because heat sealing is easy. Further, a metal foil may be laminated on the resin sheet in order to improve gas barrier properties.
The size and shape of the accommodating portion 10 may be selected as appropriate and are not particularly limited.

As shown in FIGS. 1 to 3, the pouring member 12 surrounds the cylindrical pouring cylinder portion 14 erected so as to surround the pouring outlet 12 a for pouring the contents, and the pouring cylinder portion 14. Opening seal bonded to the open end 16a of the outer frame cylinder part 16 so as to seal the opening of the cylindrical outer frame cylinder part 16 standing upright and both the extraction cylinder part 14 and the outer frame cylinder part 16 It has the part 18 and the welding part 20 welded to the accommodating part 10 formed so that it might protrude outside the outer frame cylinder part 16 below. As shown in FIGS. 1 and 4, an easily breakable line 22 is formed in the opening sealing portion 18.
As for the pouring member 12, the welding part 20 is welded with the heat seal part 10a of the upper part of the accommodating part 10 by heat sealing. That is, the pouring member 12 is provided so as to protrude from the upper portion of the accommodating portion 10.

Moreover, the pouring member 12 is connected to the pouring member of the refilling container by inserting the pouring member of the filling container into the space between the pouring cylinder part 14 and the outer frame cylinder part 16. .
As a specific example, a connection state between the refill container 1 and the refill container 2 illustrated in FIGS. 5 and 6 will be described with reference to FIG. The refillable container 2 includes a container main body 30 and a dispensing cap 34 that is attached to the upper part of the container main body 30 and includes an injection member 32 that is partially cut away in the circumferential direction. In this case, as shown in FIG. 7, by inserting the injection member 32 between the extraction tube portion 14 and the outer frame tube portion 16, the opening sealing portion 18 is broken and opened, and at the same time, The broken piece of the sealing part 18 is pushed between the extraction cylinder part 14 and the outer frame cylinder part 16, the injection member 32 of the refill container 2 and the extraction member 12 of the refill container 1 are connected, and the extraction cylinder The contents in the storage unit 10 are poured into the refill container 2 through the unit 14.

  Examples of the material of the extraction cylinder part 14, the outer frame cylinder part 16, and the welding part 20 include low density polyethylene, linear low density polyethylene, high density polyethylene, and polypropylene.

  As shown in FIG. 7, the spout 12a is smaller than the injection port 32a, and preferably fits in the region of the injection port 32a when the injection member 32 of the refill container 2 is connected. Thereby, the content poured out from the pouring port 12a through the pouring cylinder part 14 can easily enter the refill container 2 from the pouring port 32a. Therefore, the contents can be poured more stably into the refillable container 2 through the dispensing cylinder part 14.

As shown in FIGS. 3 and 4, the spout 12 a and the extraction cylinder part 14 are unevenly distributed on the side of the outer frame cylinder part 16 where the injection member 32 of the refill container 2 is inserted, and the refill container When the one extraction member 12 and the injection member 32 of the refill container 2 are connected, the spout 12a of the refill container 1 is connected to one side of the injection port 32a of the refill container 2 as shown in FIG. It is preferable that it is unevenly distributed. Thereby, when the pouring member 12 of the refill container 1 and the injection member 32 of the refill container 2 are connected, the contents in the refill container 1 are refilled through the pour cylinder portion 14 of the refill container 1. It becomes easy to pour into the container 2.
Specifically, as shown in FIG. 6, the injection port 32 a of the refill container 2 has a portion 32 c (hereinafter simply referred to as “opposing portion”) facing the notch 32 b of the injection member 32 from the center of the dispensing cap 34. 32c ")), a long and narrow opening is formed. On the other hand, the spout 12a and the extraction cylinder part 14 of the extraction member 12 in the refill container 1 are unevenly distributed on the side where the opposing portion 32c of the injection member 32 in the refill container 2 is inserted. When the extraction member 12 of the refill container 1 and the injection member 32 of the refill container 2 are connected, the spout 12a and the extraction cylinder portion 14 of the refill container 1 are opposed to the injection member 32 in the refill container 2. The spout 12a is unevenly distributed on the facing portion 32c side of the injection port 32a. As a result, the contents are poured from the spout 12a of the refilling container 1 through the spout cylinder 14 to the opposite portion 32c side of the inlet 32a, and at the same time, the main body container from the center side of the spout cap 34 at the inlet 32a. As the air in 30 is discharged, the contents are quickly and stably poured into the refill container 2.

The opening portions of the extraction tube portion 14 and the outer frame tube portion 16 are sealed by the film-shaped opening sealing portion 18 before being connected to the injection member 32 of the refill container 2. The opening sealing part 18 is bonded only to the opening end 16a of the outer frame cylinder part 16, and the extraction cylinder part 14 and the opening sealing part 18 are in close contact, but are not bonded. Although the extraction cylinder part 14 and the opening sealing part 18 are not directly bonded, the contents between the extraction cylinder part 14 and the outer frame cylinder part 16 are sufficiently adhered and sealed with the opening sealing part 18. Things do not leak out.
It is preferable that the extraction cylinder part 14 and the outer frame cylinder part 16 have the same height, or the extraction cylinder part 14 is slightly higher than the outer frame cylinder part 16. Thereby, it becomes easier to prevent the contents from leaking between the extraction tube portion 14 and the outer frame tube portion 16 during transportation or the like.

As the material of the opening sealing portion 18, any material may be used as long as it can sufficiently seal the opening portions of the extraction tube portion 14 and the outer frame tube portion 16 and breaks when the filling member of the refill container is pushed in. . For example, low density polyethylene, linear low density polyethylene, high density polyethylene, polyethylene terephthalate, metal foil, etc., and the innermost layer is polyethylene (low density polyethylene, linear low density polyethylene, high density polyethylene) and on the outside Examples include a laminate obtained by laminating metal foil and polyethylene terephthalate.
The opening sealing part 18 is bonded to the opening end 16a of the outer frame cylinder part 16 by, for example, an adhesive or heat fusion.

In addition, as shown in FIG. 4, an easily breakable line 22 is formed in the opening sealing portion 18. As a result, as shown in FIG. 7, when the injection member 32 of the refill container 2 is inserted between the extraction tube portion 14 and the outer frame tube portion 16 and the opening sealing portion 18 is broken, the broken opening seal A broken piece of the stop portion 18 is pushed between the extraction tube portion 14 and the outer frame tube portion 16.
The easily breakable line 22 may be a continuous line or an intermittent line.
Examples of the easily breakable line 22 include perforations and half-cut lines.
Examples of the method for forming the half-cut line include a method of partially removing the surface of the opening sealing portion by laser light irradiation.

The mode of the easily breakable line 22 formed in the opening sealing portion 18 is that the broken piece of the opening sealing portion 18 broken by the injection member 32 does not cover the opening of the dispensing cylinder portion 14, and the broken fragment is removed from the dispensing cylinder portion. Any form may be used as long as it is pushed between the outer frame cylinder portion 16 and the outer frame cylinder portion 16.
For example, when forming one easy-break line 22 in the opening sealing part 18, the easy-breaking line 22 is formed in the opening sealing part 18 along the tangent line in contact with the extraction cylinder part 14, and pouring is performed. It is preferable that a region on the opposite side of the contact point between the extraction tube portion 14 and the easily breakable line 22 with respect to the tube portion 14 is an insertion region into which the facing portion 32c of the injection member 32 is inserted. In this example, an easily breakable line 22 is formed along a tangent line in contact with the extraction cylinder portion 14 at a position farthest from the outer frame cylinder portion 16 on the side where the extraction cylinder portion 14 is unevenly distributed. The region including the linear portion a that is the closest to the frame tube portion 16 (the region on the opposite side of the contact point between the extraction tube portion 14 and the easily breakable line 22) is the insertion region of the facing portion 32c of the injection member 32. .
Thereby, when the injection member 32 of the refillable container 2 is inserted between the extraction tube portion 14 and the outer frame tube portion 16, the opening sealing portion 18 is broken while being cleaved along the easily breakable line 22. A broken piece of the opening sealing portion 18 closer to the extraction tube portion 14 than the easily breakable line 22 is pushed between the extraction tube portion 14 and the outer frame tube portion 16 by the injection member 32. On the other hand, the fracture piece of the opening sealing portion 18 on the side opposite to the extraction member 14 of the easily breakable line 22 remains as the opening sealing portion 18 is cleaved along the easily breakable line 22, and the injection member 32 is inserted. It is not drawn into the area side. Therefore, when the pouring member 12 of the refilling container 1 and the injection member 32 of the refillable container 2 are connected, the broken piece of the opening sealing portion 18 is prevented from covering the opening of the pouring cylinder portion 14. Therefore, the distribution channel for the contents can be secured stably.

The refill container 1 described above can sufficiently secure the distribution channel of the contents, and can be refilled easily and stably in a short time without spilling the contents. Factors for obtaining the effect are considered as follows.
In the conventional refilling container of (i) described above, since the injection member of the refilled container is inserted into the extraction part of the refilling container, the broken piece of the sealing member that seals the extraction part is injected by the injection member. In some cases, the flow path was pushed into the outlet and the flow path in the outlet was blocked by the broken pieces.
On the other hand, in the refill container 1, an outer frame cylinder part 16 is provided outside the extraction cylinder part 14, and the openings of the extraction cylinder part 14 and the outer frame cylinder part 16 are sealed by the opening sealing part 18, Since the injection member 32 of the refill container 2 is inserted between the extraction cylinder part 14 and the outer frame cylinder part 16 to break the opening sealing part 18, the broken pieces of the opening sealing part 18 are extracted by the injection member 32. It is not pushed into the cylinder part 14. Therefore, it is suppressed that the distribution path in the extraction cylinder part 14 is blocked by the broken piece of the opening sealing part 18. Further, the opening sealing portion 18 is formed with an easily breakable line 22 so that a broken piece of the opening sealing portion 18 is stably pushed between the extraction tube portion 14 and the outer frame tube portion 16. Therefore, since it is also suppressed that the broken piece of the opening sealing portion 18 covers the opening of the dispensing cylinder portion 14, the contents can be refilled easily and stably.
Further, the refill container 1 has a simpler structure than the refill container (ii) described above. And since the special mechanism for breaking through the opening sealing part is not required on the refill container side, the refill container of the present invention is very useful as a refill container for the existing refill container.

The refill container of the present invention is not limited to the refill container 1 described above.
For example, the mode of forming one easy-break line 22 is not limited to the above-described mode, and an easy-break line is formed in the opening sealing portion 18 along a tangent line in contact with the pouring tube portion 14, and the pouring tube is formed. If the region on the opposite side of the contact between the extraction tube portion 14 and the easily breakable line 22 with respect to the portion 14 is the insertion region of the opposite portion of the injection member, the easily breakable line may be formed in any direction. Good.

Further, the number of easily breakable lines 22 is one in this example, but may be two or more.
When two or more easily breakable lines are formed in the opening sealing portion, for example, as shown in FIGS. 8A to 8C, the opening sealing portion 18 passes through the center of the extraction tube portion 14. 1 easy breakable line 22a and a second easy breakable line 22b that does not pass over the extraction member 14 and intersects the first easy breakable line 22a are formed. The aspect on the opposite side of the intersection of the line 22a and the second easily breakable line 22b may be an insertion area of the facing portion 32c in the injection member 32. Further, as shown in FIG. 8D, in addition to the first easily breakable line 22a and the second easily breakable line 22b, the first easily breakable line 22a and the second easily breakable line 22a do not pass through the extraction member 14. A third easily breakable line 22c intersecting at the intersection of the easily breakable line 22b is formed, and a region opposite to the intersecting point with respect to the extraction member 14 is an insertion region of the facing portion 32c in the injection member 32. An aspect may be sufficient.
In the example of FIGS. 8A to 8D, an area including the linear portion a where the distance between the extraction cylinder part 14 and the outer frame cylinder part 16 is the closest is set as the insertion area.

Moreover, when forming two easily breakable lines in an opening sealing part, as shown to FIG. 9 (A)-(C), the two which cross the opening sealing part 18 on the outer side of the extraction cylinder part 14 The easy-breaking lines 22d and 22e are formed, and the distance d between the intersection of the easy-breaking lines 22d and 22e and the outer frame cylinder part 16 farthest from the intersection is the extraction cylinder part 14 and the outer frame cylinder part 16 The depth D (FIG. 2) is not more than twice, and the region opposite to the intersection point with respect to the extraction tube portion 14 is the insertion region of the facing portion 32c in the injection member 32. There may be. In this example, the region including the filament portion a in which the extraction tube portion 14 is unevenly distributed on one side of the outer frame tube portion 16 and the distance between the extraction tube portion 14 and the outer frame tube portion 16 is the closest is the injection. It is set in the insertion region of the facing portion 32 c of the member 32. And the intersection of two easily breakable lines 22d and 22e is located on the extended line of the said line part a.
If the distance d is equal to or less than twice the depth D, the broken pieces of the opening sealing portion 18 that are folded into two by being pushed in by the injection member 32 are extracted from the extraction tube portion 14 and the outer frame tube portion 16. It becomes difficult to cover the opening part of the extraction | pouring cylinder part 14 between these.

In addition, when two easily breakable lines are formed in the opening sealing portion, they are easy as long as the broken pieces of the opening sealing portion can be sufficiently pushed between the extraction tube portion 14 and the outer frame tube portion 16. The intersection of the break lines and the insertion region of the facing portion 32 c in the injection member 32 may be provided so as to be shifted from the opposite position with respect to the extraction tube portion 14. Specifically, the embodiment illustrated in FIGS. 9D and 9E can be given. In this example, the extraction cylinder part 14 is unevenly distributed on one side of the outer frame cylinder part 16, and intersects the opening sealing part 18 outside the extraction cylinder part 14, and the position of the intersection is the line. Two easily breakable lines 22d and 22e are formed at positions shifted from the extended line of the strip portion a, and a region including the strip portion a is set as an insertion region of the facing portion 32c in the injection member 32. . In the example of FIG. 9D, two easily breakable lines 22d and 22e are formed up to their intersections. In the example of FIG. 9E, the two easily breakable lines 22d and 22e are formed so as to reach the opposite side of the outer frame cylinder portion 16 through the respective intersections.
9 (D) and FIG. 9 (E), even if it is an intersection of the extension line of the filament portion a and the easily breakable line 22d, 22e (in this example, the easily breakable line 22e and 2) of the depth D (FIG. 2) between the extraction cylinder part 14 and the outer frame cylinder part 16 is a distance e between the extended line and the outer frame cylinder part 16 on the line part a side. If it is less than double, the broken piece of the opening sealing portion 18 can be sufficiently pushed between the extraction tube portion 14 and the outer frame tube portion 16.

  4, 8 </ b> A to 8 </ b> D, and 9 </ b> A to 9 </ b> E, the easily breakable line is illustrated in particular in a part in the circumferential direction of the pouring member 12 of the refill container 1. When connecting to the refill container 2 having the cut-out injection member 32, the broken portion of the opening sealing portion 18 is removed while the opening portion of the dispensing cylinder portion 14 is prevented from being covered. It is preferable in that it can be pushed in more stably between the outer frame cylinder portion 16 and the outer frame cylinder portion 16. Especially, when making the insertion area | region of the opposing part 32c in the injection | pouring member 32 into the linear part a with the shortest distance of the extraction | pouring cylinder part 14 and the outer frame cylinder part 16, FIG. 4, FIG. (D) and an aspect like the example of FIG. 9 (A)-(C) are more preferable.

In addition, if the mode of the easily breakable line formed in the opening sealing portion is formed so that the broken piece of the opening sealing portion broken by the injection member is pushed between the extraction tube portion and the outer frame tube portion Aspects other than those described above may be used. For example, the mode of the easy break line may be a mode in which another easy break line is added to the above-described mode.
Moreover, when forming two or more easily breakable lines, those easily breakable lines do not need to cross. Further, if the broken piece of the opening sealing portion 18 is within the range where the injection member 32 can push the broken piece between the extraction tube portion 14 and the outer frame tube portion 16, the easy break line reaches the portion of the outer frame tube portion 16. It does not have to be. Further, the easily breakable line is not limited to a straight line shape, and may be a curved line shape.
Moreover, the aspect which the center axis | shaft of the extraction cylinder part and the outer frame cylinder part corresponded may not be unevenly distributed in the outer frame cylinder part.
