Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an upright extraction bag that is attached to a container such as a cup in an upright manner to perform extraction.
[0002]
[Prior art]
3 and 4 show an upright extraction bag conventionally used. As shown in FIG. 3, the bag includes a bag body 100 in which extraction raw materials are stored, and a pair of outer surface sheets 110 that are bonded to the outer surface of the bag body 100 facing each other by bonding. Although the bag body 100 has a flat shape, the bag body 100 can be inflated by a peeling force acting in the opposite direction.
[0003]
The pair of outer surface sheets 110 are integrally formed with locking pieces 120. The locking piece 120 is integrated with the outer sheet 110, but a cut line 121 formed by cutting the outer sheet 110 is provided around the locking piece 120, and the outer sheet 110 is separated from the cut line 121. It is possible to cause. In this case, one side of the cut line 121 is a continuous line 122 such as a perforation, and even if it is caused, the locking piece 120 continues to be connected to the outer sheet 110 at the continuous line 122 portion. To do. In addition, a slit 130 is formed in the locking piece 120, and the bag body 100 is brought into an upright state by inserting an edge of a container such as a cup into the slit 130.
[0004]
FIG. 4 shows the extraction state of the upright extraction bag. This extraction causes the locking piece 120 from both sides of the bag body 100 and inserts the edge of the cup 140 into the slit 130 of the generated locking piece 120. Since the locking piece 120 is locked to the cup 140 by this insertion, a peeling force acts on the opposing outer surface of the bag body 110 so that the entire bag body 110 swells. At the same time, since both sides of the bag body 110 are supported by the cup 140 via the locking pieces 120, the bag body 110 is attached to the cup 140 in an upright state. In this attached state, by pouring hot water or the like into the bag body 100 from above, the extraction raw material in the bag body 110 can be extracted.
[0005]
[Problems to be solved by the invention]
However, the conventional upright extraction bag has the following problems.
(1) When attaching to the cup 140, the bag body 100 tends to be inclined, and due to this inclination, the extraction raw material spills out of the bag body 100 and falls into the cup 140 during extraction. This is because the slit 130 of the locking piece 120 is not securely locked to the edge of the cup 140 and the locking force to the cup 140 is small, and when the locking piece 120 is caused. In addition, since the locking piece 120 pulls the entire outer sheet 110, the bag body 10 is pulled toward the continuous line 122 side, which is a joint portion between the outer sheet 110 and the locking piece 120.
[0006]
(2) It is difficult to cause the locking piece 120 from the outer surface sheet 110. Further, if the hook 100 is hooked and forcibly caused, the bag body 100 and the locking piece 120 are broken.
[0007]
The present invention has been made in consideration of such conventional problems, and the bag body is not inclined and attached to a cup or the like, and the locking piece can be easily raised. An object is to provide an upright extraction bag.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 is joined to a liquid-permeable flat bag body which is bulging and deformable and which contains an extraction raw material therein, and an outer surface facing the bag body. A pair of outer sheets and a slit into which the external members are inserted, and are integrally formed so as to be able to be caused in each of the pair of outer sheets, and the slits are locked to the external members. A locking piece for raising the bag body with respect to the outside members in a state where the bag body is inflated, and the locking piece is surrounded by a continuous cut line and a continuous line, and the cut line is a boundary. And can be caused from the outer sheet from the connecting line as a starting point, a stress concentrating portion is provided on the opposite side of the locking piece to the connecting line, and the outer sheet is At the outer side of the wiring While being joined to the outer surface of the serial bag, the outer side portion of the stress concentration portion has a bag body and a non-joined state, wherein the insertion start end of the outer s wood of the slit is squeezed And
[0009]
In the present invention, by applying a force in the vicinity of the stress concentration portion, the force concentrates on the stress concentration portion, so that the locking piece can be caused from the stress concentration portion. For this reason, the locking piece can be easily raised.
[0010]
Then, external members such as a cup are inserted into the slits of the locking piece while the locking piece is raised. In this insertion, since the insertion start end portion of the slit is narrowed down, the slit is locked to the external members while being engaged with the external members such as a cup, and a strong locked state is obtained. Moreover, the portion of the outer sheet on the outer side of the stress concentration portion is in a non-joined state where it is not joined to the bag. Therefore, the bag body is not pulled by the entire outer sheet. By these, the bag body can be attached to the outside members without inclining.
[0011]
A second aspect of the present invention is the first aspect of the present invention, wherein the pair of outer surface sheets are provided in a plane-symmetrical position with respect to the bag body.
[0012]
In this invention, since a pair of outer sheet | seat is provided in a plane symmetrical position, the effect | action mentioned above can be performed from a plane symmetrical position. For this reason, the attachment to the external members which do not tilt can be performed more reliably.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1A and 1B are a front view and a rear view of an embodiment of the present invention, and FIG. 2 is a perspective view at the time of extraction. The upright extraction bag 1 of this embodiment includes a bag body 2, a pair of outer surface sheets 3, 4, and locking pieces 5, 6 formed on the outer surface sheets 3, 4.
[0014]
The bag body 2 is formed in a rectangular shape having a flat outer shape, and an extraction raw material (not shown) is accommodated therein. As a raw material for extraction, it is possible to select an appropriate material such as a taste product such as coffee powder, green tea, black tea, a seasoning such as shavings, dashi kelp, boiled sardines, or a decoction. The bag body 2 is formed in a bag shape by overlapping sheet-like packaging materials and sealing the peripheral portion. As the wrapping material, a mesh shape or papermaking knitted with synthetic resin yarns vertically and horizontally is used, and as a result, the entire bag body 2 has liquid permeability. Further, since the packaging materials are overlapped and formed into a bag shape, they can be easily swelled and deformed when opposing tensile forces act.
[0015]
In the bag body 2 in this embodiment, perforated opening lines 2a are formed laterally in the upper part, and the raw material for extraction is sealed between the opening line 2a and the seal line 2b at the lower end. Is done. The opening line 2a can be easily separated from the bag body 2, and the upper portion of the bag body 2 can be opened by separating the opening line 2a (see FIG. 2). Extraction of the raw material for extraction is performed by pouring hot water or the like into the bag body 2 from above in the open state of the upper portions.
[0016]
The pair of outer surface sheets 3 and 4 are made of rectangular paper material, resin material, or the like, and are joined to the opposed outer surfaces 2c and 2d of the flat bag body 2 by means such as adhesion, heat welding, and ultrasonic welding. In addition, although the joining site | part to the bag body 2 of the outer surface sheets 3 and 4 is a little lower than the center part in the outer surfaces 2c and 2d of a bag body, a center part or its upper part may be sufficient. .
[0017]
The locking pieces 5 and 6 are integrally formed on the outer surface sheets 3 and 4 through the cut lines 5b and 6b formed on the outer surface sheets 3 and 4, respectively. That is, the locking pieces 5 and 6 have cut lines 5b and 6b around them, and can be caused from the outer sheet 3 and 4 with the cut lines 5b and 6b as a boundary. Also, continuous lines 5a and 6a that are not cut are formed on one side of the locking pieces 5 and 6 that are part of the cut lines 5b and 6b. The engaging pieces 5, 6 are connected to the outer surface sheets 3, 4. Accordingly, the locking pieces 5 and 6 are caused from the outer surface sheets 3 and 4 with the connecting lines 5a and 6a as starting points.
[0018]
Stress concentrating portions 5c and 6c are formed on the side of the locking pieces 5 and 6 opposite to the side where the continuous lines 5a and 6a are formed. The stress concentration portions 5c, 6c in this embodiment are formed by causing the cut lines 5b, 6b located on the side opposite to the connecting wires 5a, 6a to rise toward the locking pieces 5, 6 and on both sides of the raised portions ( It is formed by recessing the upper and lower sides. Therefore, the stress concentration parts 5c and 6c are configured by making the opposite sides of the cut lines 5b and 6b opposite the continuous lines 5a and 6a corrugated. When an external force such as a pressing force is applied to the stress concentration portions 5c and 6c, the external force is concentrated, and the locking pieces 5 and 6 can be easily caused from the outer surface sheets 3 and 4 by the concentration of the force.
[0019]
Slits 7 and 8 are formed in the locking pieces 5 and 6. The slits 7 and 8 are formed in a substantially U shape with the lower end portion opened, and as shown in FIG. 2, the edge portion 21 of the cup 20 as an external member is inserted. Since the locking pieces 5 and 6 are locked to the cup 20 by this insertion, the bag body 2 can be attached to the cup 20 in an upright state. The slits 7 and 8 are shaped to be narrower than other portions so that the widths of the insertion start end portions (lower end portions) 7a and 8a into which the edge portion 21 of the cup 20 is inserted are minimized. The insertion start end portions 7a and 8a thus narrowed can be engaged with the cup 20, and the engagement pieces 5 and 6 are firmly engaged with the cup 20 by the engagement of the insertion start end portions 7a and 8a. It becomes.
[0020]
Furthermore, in this embodiment, the outer surface sheets 3 and 4 are not bonded to the outer surface of the bag body 2 on the front surface, but have non-bonded portions 3a and 4a that are not bonded to the bag body 2. . The non-joining portions 3a and 4a are provided on the outer sides of the stress concentration portions 5c and 6c in the outer surface sheets 3 and 4. In FIG. 1, a portion indicated by a broken line is a joining portion 9 where the outer sheets 3 and 4 are joined to the bag body 2, and the outer portions of the continuous lines 5 a and 6 a and the slits 7 and 8 in the outer sheets 3 and 4. Is joined to the bag body 2. By forming such non-joining portions 3a and 4a, the outer sheet 3 and 4 do not pull the bag body 2 in the non-joining portions 3a and 4a, and the bag body 2 excludes the non-joining portions 3a and 4a. Only the part is pulled by the outer sheets 3 and 4 so as to swell.
[0021]
As shown in FIG. 1, the upright extraction bag 1 of such an embodiment has the outer sheets 3 and 4 joined so as to be plane-symmetric with respect to the bag body 2. The locking pieces 5 and 6 are flush with the outer sheets 3 and 4 and are supplied in a state of being flush with each other in a gas barrier outer bag (not shown). When the outer bag is sealed and taken out from the outer bag, the locking pieces 5 and 6 are flush with the outer surface sheets 3 and 4, and therefore hinder filling and taking out of the outer bag. There is nothing.
[0022]
At the time of extraction, the upright extraction bag 1 is taken out from the outer bag and pressed near the stress concentration portions 5c and 6c. Since this pressing force is concentrated on the stress concentration portions 5c and 5c, the stress concentration portions 5c and 6c are easily separated from the outer surface sheets 3 and 4. Therefore, it can be caused by the fingers of the locking pieces 5 and 6, and the locking pieces 5 and 6 can be easily raised, and an excessive force does not act on the raising. Stop pieces 5 and 6 are not torn.
[0023]
After the locking pieces 5 and 6 are raised, the portion above the opening line 2a is cut off, and the edge 21 of the cup 20 is inserted into the slits 7 and 8 of the locking pieces 5 and 6, and the locking pieces 5 and 6 are inserted. Is locked to the cup 20. In this locking, since the insertion start end portions 7a and 8a of the slits 7 and 8 are engaged with the cup 20, the entire locking pieces 5 and 6 are locked firmly. Further, since the peeling force acts on the outer surfaces 2c and 2d of the bag body 2 from the outer surface sheets 3 and 4 by the locking of the locking pieces 5 and 6, the bag body 2 swells and deforms and can be extracted. It becomes.
[0024]
When the locking pieces 5 and 6 are locked to the cup 20, the outer surface sheets 3 and 4 connected to the locking pieces 5 and 6 via the connecting wires 5 a and 6 a inflate the bag body 2. Act on. On the other hand, the outer sheets 3 and 4 are provided with non-joined portions 3a and 4a that are not joined to the bag body 2. Moreover, when the non-joining portions 3a and 4a are located on the outer side of the stress concentration portions 5c and 6c (that is, on the opposite side of the connecting wires 5a and 6a), Since the inducing force is transmitted to the non-joined portion 3a and the picture 4a via the continuous lines 5a and 6a, the non-joined portions 3a and 4a behave like being peeled from the bag body 2. For this reason, the bag body 2 is not pulled by the entire outer surface sheets 3 and 4, and the bag body 2 can be in an upright state without tilting. Thereby, the raw material for extraction inside the bag body 2 is prevented from spilling down.
[0025]
Furthermore, in this embodiment, since the outer surface sheets 3 and 4 are provided in a plane symmetric position with respect to the bag body 2, the above operation can be performed in the plane symmetric position and the cup 20 does not tilt. Can be more reliably attached.
[0026]
【The invention's effect】
As described above, according to the first aspect of the present invention, the locking piece can be easily caused by the stress concentration portion, and the throttle at the insertion start end portion of the slit is provided, and the outer sheet bag body is provided. Since the non-joined state is provided, the bag body can be erected without tilting.
[0027]
According to invention of Claim 2, the standing state which a bag body does not incline can be further ensured.
