Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a package in which tea leaves such as green tea, black tea and oolong tea, powders of processed products such as coffee powder, soup stock such as bonito shaving powder and dried sardines, and other raw materials for extraction are enclosed.
[0002]
[Prior art]
The package which enclosed the raw materials for extraction (henceforth the contents) as mentioned above is devised to improve extraction efficiency. 16 to 18 show a conventional package 200 described in Japanese Patent Laid-Open No. 3-98870 by such a device.
[0003]
The package 200 includes a bag body 210 formed in a tetra shape and a hanging thread 220 attached to the bag body 210, and one end of the hanging thread 220 is one apex or one surface of the bag body 210. It is fixed to the approximate center part of. Reference numeral 230 denotes a tag attached to the other end of the hanging thread 220.
[0004]
FIG. 16 shows a form in which the package 200 is housed in an outer bag (not shown). A tetra-shaped bag 210 is folded at an appropriate portion, and the hanging thread 220 is wound around the folded state. . Then, the tag 230 is lightly adhered to the outer surface of the bag body 210, so that the hanging thread 220 holds the folded state of the bag body 210 and is put into the outer bag.
[0005]
At the time of extraction, as shown in FIGS. 17 and 18, the tag 230 is held, the bag body 210 is suspended by the hanging thread 220, and immersed in the hot water in the container 150. FIG. 17 shows a case where one end of the hanging thread 220 is fixed to one apex of the bag body 210, and the triangular surface is located on the lower side. FIG. 18 shows a case where one end of the hanging thread 220 is fixed to one surface of the bag body 210, and one vertex is located on the lower side. In any of these cases, since the bag body 210 is tetra-shaped, the inner space of the bag body 210 is wide and can be filled with many contents, and the degree of contact between the contents and hot water is increased, so that efficient extraction is possible. It can be carried out.
[0006]
[Problems to be solved by the invention]
However, the conventional package 200 has a problem that it is difficult to be accommodated in the outer bag because the folded state is bulky and is easily hooked with the outer bag. In the folded state, as shown in FIG. 16, the outer shape is simply rounded by the hanging thread 220. For this reason, an external appearance deteriorates, it is unsightly at the time of taking out from an outer bag, and the commercial value is falling.
[0007]
Further, in the conventional package 200, the hanging thread 220 and the tag 230 are likely to fall into the container 150 during extraction, and not only the sanitary condition is deteriorated but also the ink printed on the tag 230 oozes out and removes hot water. Has a fouling problem. In order to prevent this drop, it is conceivable to secure a sufficient length by wrapping the hanging thread around the bag body twice or triple, but not only the appearance as a package body deteriorates but also to the outer bag. It is not practical because the hanging thread is easily caught with the outer bag during storage of the bag, and it is difficult to wind it twice or triple on the production line of the package.
[0008]
The present invention has been made in consideration of the above-described conventional problems, and can be brought into an orderly folded state without being bulky, can improve the appearance, and can be hung without lengthening the hanging thread. It is an object of the present invention to provide a package capable of reliably preventing a thread or tag from falling into a container.
[0009]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 is a bag body having liquid permeability and flexibility in which a bent portion is formed on a side surface continuously connecting an upper surface and a lower surface, and the side surface is folded. One end is fixed to the upper surface or the lower surface of the bag body, and at least one hanging thread wound around the outer periphery of the folded bag body and an engaging portion that is locked to the outside members are formed. And a tag attached to the other end and releasably joined to the upper or lower surface of the folded bag.
[0010]
In the present invention, the bag is flattened in a normal state by folding the side surface. For this reason, it is not bulky and can be easily stored in the outer bag. Further, when the side surface is folded, the upper surface and the lower surface are overlapped, and the appearance is improved with a well-formed shape.
[0011]
Moreover, the tag is physically coupled to the external members by locking the locking portions formed on the tags to the external members such as containers. For this reason, the tag does not fall off from the outside, and the hanging thread and the tag do not drop. Therefore, it is not necessary to lengthen the hanging thread to prevent the sagging.
[0012]
At the time of extraction, the side surface extends from the folded state due to the weight of the swollen contents and the elongation of the packaging material used for the bag. Thereby, although a bag body will be in an expansion | deployment state, since the side surface currently folded is the expansion | deployment state extended, the inside becomes a large space. For this reason, the contents are in good contact with hot water and the extraction efficiency is improved. Further, the contents are filled in a wide space to be developed, and therefore a sufficient amount can be filled.
[0014]
In this invention, the hanging thread is wound around the outer periphery of the folded bag body, and the tag is joined to the folded bag body, so that the hanging thread does not leave the bag body and is hooked with the outer bag. And can be smoothly stored in the outer bag.
[0015]
In each of the packaging bodies described above, the side surface may be folded in a direction in the plane of the upper surface and the lower surface of the bag body, or may be folded in a direction out of the plane of the upper surface and the lower surface.
[0016]
Moreover, the upper surface and the lower surface of the bag body may be polygonal, may be a polygon having a curved corner portion, or may be an outer shape surrounded by a curve. By adopting the latter two shapes, the contents are not caught in the bag and do not stay, so the contents move smoothly in the bag and the extraction efficiency is improved.
[0017]
The locking portion may be a slit having one end opened at the outer peripheral end of the tag and the other end extending in the plane of the tag, and is partially connected to the tag through a closed loop cut line that is partially opened. It may be a lip formed on the tag so that it can be raised in a state where it is connected to the tag.
[0018]
The slit is locked to the external material by inserting the external material, and the lip is locked to the external material by sandwiching the external material. Therefore, the tag and the hanging thread connected to the tag do not fall into the outside materials.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1-6 shows the package 1 of one Embodiment of this invention. The packaging body 1 includes a bag body 2, contents 3 (see FIG. 2) sealed in the bag body 2, and a hanging thread 20 attached to the bag body.
[0020]
The bag body 2 is made of a wrapping material made of a material having fluid permeability that allows liquid to pass through and flexibility that can be folded and unfolded. As the packaging material having liquid permeability and flexibility, a mesh body of a synthetic resin yarn knitting, a nonwoven fabric, a nylon bag, and the like can be selected. This packaging material is supplied in the form of a long sheet, and is formed into the shape shown in the figure by folding, sealing, and cutting.
[0021]
As shown in FIG. 2, the bag body 2 is formed by opposing the upper surface 4 and the lower surface 5, and connecting the upper surface 4 and the lower surface 5 with left and right side surfaces 6 and 6. In this embodiment, the upper surface 4 and the lower surface 5 are formed in a horizontally long hexagonal shape, and the left and right side surfaces 6, 6 are connected to the upper surface 4 and the lower surface 5 in the length direction of the bag body 2. That is, as shown in FIGS. 1 and 3, the upper surface 4, the lower surface 5, and the side surface 6 are integrated with each other at both ends 2 a and 2 b in the length direction of the bag body 2. In between, the side surface 6 is folded in the in-plane direction of the upper surface 4 and the lower surface 5.
[0022]
1 to 3, reference numeral 7 denotes a bent portion for folding the side surface 6. The bent portion 7 is located at a substantially central portion of each side surface 6 and is formed in a straight line shape along the length direction of the long side of the bag body 2. The left and right side surfaces 6 are folded up and down with the bent portion 7 as a boundary. In FIG. 2, reference numeral 15 denotes a folded portion formed on the side surface 6. By such folding, the upper surface 4 and the lower surface 5 are overlapped with each other via the side surface 6, whereby the bag body 2 can be formed into a thin flat shape without being bulky.
[0023]
One end 21 of the hanging thread 20 is fixed to a substantially central portion of the upper surface 4 of the bag body 2 by ultrasonic welding, heat welding or the like. A tag 40 made of a piece of paper, a plastic piece or the like is attached to the other end 22 of the hanging thread 20, and the tag 40 can be peeled off from the upper surface 4 of the bag body 2 as shown in FIGS. 2 and 3. It is joined. Such joining is performed by applying a hot-melt adhesive to the lower surface of the tag 40 and making the hot-melt adhesive heat sensitive to develop an adhesive force. In such joining, the tag 40 can be easily peeled off from the bag body 2 with a finger or the like. The tag 40 can also be joined by spot welding or other means.
[0024]
In this embodiment, as shown in FIGS. 2 and 3, the hanging thread 20 is wound around the outer periphery of the bag body 2 from one end 21 fixed to the upper surface 4 of the folded bag body 2. The tag 40 is wound around the outer surface of the bag body 2 by being drawn around the upper surface 4 of the body 2 and being joined to the upper surface 4 of the bag body 2. In this case, the hanging thread 20 is wound around the short side of the bag body 2.
[0025]
As described above, the one end 21 and the other end 22 (tag 40) are fixed to the same surface of the bag body 2 and wound around the short side of the bag body 2, so that the hanging thread 20 is inadvertently wound. It will not be out of the rotation state. For this reason, even if this hanging thread 20 is wound and stored in the outer bag 8 (see FIG. 3), the hanging thread 20 is not caught by the outer bag 8. In addition, the outer bag 8 is gas barrier property, and the content 3 is prevented from being oxidized or scented by being stored in the outer bag 8.
[0026]
The storage in the outer bag 8 is performed in a state where the side surface 6 of the bag body 2 is folded. In this folded state, the entire bag body 2 is flat and not bulky, so that the bag body 2 itself is not caught by the outer bag 8 in addition to the hanging thread 20, and can be smoothly stored in the outer bag 8. Can be done. Furthermore, in the folded state of the bag body 2, the upper surface 4 and the lower surface 5 have a well-formed shape that completely overlaps. For this reason, the external appearance of the bag body 1 is improved, the interest when the outer bag 8 is opened and taken out is improved, and the commercial value is also increased.
[0027]
As shown in FIG. 4, the tag 40 includes a main body 41 and a slit 42 as a locking portion. The main body 41 is formed into a rectangular thin small piece by a piece of paper, a synthetic resin piece, or other material. The main body 41 may be a small piece, and may be an oval, a circle, a triangle, a polygon, or other shapes.
[0028]
One end 42 a of the slit 42 opens at the outer peripheral end on one side of the main body 41, and the other end 42 b extends linearly within the surface of the main body 41. The slit 42 extends to the vicinity of the center of the main body 41, and a circular stop hole 43 having a diameter larger than the width of the slit 42 communicates with the other end 42b. The slit 42 is locked to the outside members such as the container 9 (see FIG. 5).
[0029]
FIG. 5 shows a state at the time of extraction of the package 1 of this embodiment, and hot water 10 is filled in the inside of the container 9 as an external member. At the time of extraction, one end 42a of the opened slit 42 faces the edge of the container 9, and the edge of the container 9 is inserted into the slit 42 from the one end 42a. The insertion is stopped when the edge of the container 9 reaches the stop hole 43, and the main body 41 of the tag 40 sandwiches the edge of the container 9 by the insertion. The tag 40 is locked to the container 9 by this pinching.
[0030]
In this way, the main body 41 is locked to the edge of the container 9 so that the tag 40 does not fall into the container 9. For this reason, the tag 40 is not immersed in the hot water 10, no sanitary problem occurs, and the ink printed on the tag 40 does not ooze out. Further, it is not necessary to lengthen the hanging thread 20 in order to prevent the tag 40 from dropping, the consumption of the thread material is reduced, and the hanging thread 20 itself is not entangled or entangled with the outer bag 8, so that handling is easy. Will improve.
[0031]
Furthermore, in this embodiment, the large-diameter stop hole 43 communicates with the slit 42, and the stop hole 43 absorbs or relaxes the stress caused by the insertion of the edge of the container 9. For this reason, even if the edge part of the container 9 is thicker than the width | variety of the slit 42, the slit 42 is not torn and reliable locking can be performed.
[0032]
At the time of extraction, hot water enters the bag body 2 and is absorbed by the contents 3 inside, so that the contents 3 swells. The side surface 6 extends from the folded state and the upper surface 4 and the lower surface 5 are mutually connected by the interaction of the weight of the swollen contents 3 and the thermal expansion and slackness of the packaging material due to the contact of the bag 2 with hot water or one of the actions. It will be in the unfolded state apart.
[0033]
In such an unfolded state, the inside of the bag body 2 becomes a wide space, and the contents 3 come into contact with hot water in this space, so that extraction efficiency is good and extraction can be performed in a short time. In addition, this means that the space that is widened by the expansion is pre-filled with the contents, whereby the filling amount of the contents into the bag body 2 can be increased, and a sufficient amount of the contents can be filled. It becomes possible. Here, as the contents 3, it is possible to use tea leaves such as green tea, black tea, oolong tea, raw materials such as coffee powder, shavings, dashi kelp, dried sardines, pharmaceuticals such as decoction, and other extraction raw materials.
[0034]
At the time of the above extraction, the hot water 10 is also stirred with a spoon or the like, whereby a stirring flow is generated in the container 9. In this embodiment, since the internal space of the bag body 2 is expanded as described above, the contents 3 can freely move in the wide internal space. For this reason, the degree of contact between the contents 3 and the hot water is increased, and the extraction efficiency is further improved.
[0035]
FIG. 6 shows the effect of the stirring flow 12. In this embodiment, the bag body 2 is a horizontally long hexagonal polygon, and each corner portion 11 has an obtuse angle exceeding 90 degrees. For this reason, the corner part 11 does not block the movement of the contents, and the contents 3 do not get caught in the corner part 11 or stagnate in the corner part 11, and smoothly move around the bag body 2 together with the stirring flow 12. can do. Therefore, the extraction efficiency by stirring can be improved more reliably.
[0036]
FIG. 7 shows another form of folding the bag body 2. The upper surface 4 and the lower surface 5 of the bag body 2 have a square shape or a rectangular shape, and the left and right sides of the upper surface 4 and the lower surface 5 are connected by side surfaces 6. Each side surface 6 has a bent portion 7 and is folded in two by the bent portion 7. This folding is performed so that the upper surface 4 and the lower surface 5 overlap each other, but the side surface 6 is folded outwardly from the surface where they overlap.
[0037]
That is, in this folding, the side surface 6 has a flap shape and protrudes in the direction out of the upper surface 4 and the lower surface 5. Thus, even when folded in an out-of-plane direction, the width of the bag body 2 at the time of folding is only widened, it is a thin flat shape that does not become bulky, and it can have a well-formed outer shape, There is no obstacle to storage in the outer bag. Further, at the time of extraction, since the folded side surface 6 extends smoothly, the space in the bag body 2 is increased, and the extraction efficiency can be increased.
[0038]
8 and 9 show still other forms of the planar shape of the bag body 2, that is, the upper surface 4 (or the lower surface 5). In these cases as well, the upper surface 4 and the lower surface 5 are connected by the folded side surface 6 as described above.
[0039]
The bag body 2 shown in FIG. 8 has a shape in which the upper surface 4 (and the lower surface 5) of the bag body 2 is a quadrangle, but the corner portions 30 at the four corners are cut off by curves. More specifically, in the same figure (a), it is an inner arc-shaped curve cut by an arc from the outside of the upper surface 4, and in the same figure (b), it is cut by an arc from the inner side of the upper surface 4. The outer arc is curved. Thus, by making the corner part 30 into a curved shape, the contents 3 in the bag body 2 can be smoothly moved without being caught by the corner part 30 and staying. For this reason, the degree of contact with the contents 3 increases, and the extraction efficiency can be increased.
[0040]
9A, the upper surface 4 of the bag body 2 has a circular shape, FIG. 9B shows a dharma shape in which the circular shapes are continuously provided, and FIG. These shapes have an outer shape in which the upper surface 4 is surrounded by a curve, and the contents 3 in the bag 2 can be smoothly moved without being caught. For this reason, extraction efficiency can be increased also by these shapes.
[0041]
In the above embodiment, the number of the bent portions 7 for folding the side surface 6 is one, but two or more may be formed on each side surface, and the side surface 6 may be folded in a bellows shape. Moreover, the hanging thread 20 should just have at least 1 piece, and may be 2 or more. By providing a plurality of the hanging threads 20 in this manner, the suspension of the bag body 2 is stable, so that the extraction can be performed by shaking the bag body 2, and the extraction efficiency is further improved.
[0042]
10 and 11 show other forms of the tag 40, respectively. In the tag 40 shown in FIG. 10A, the slit 42 has a single width without a stop hole communicating with the other end 42 b of the slit 42 extending in the plane of the main body 41. Even in this case, the tag 40 can be locked by inserting the edge of the container 9 into the slit 42.
[0043]
In the tag 40 shown in FIG. 10B, one end 42 a of the slit 42 opens at one corner of the main body 41, and the other end 42 b extends obliquely in the plane of the main body 41 from this corner. . The other end 42b of the slit 42 reaches a substantially central portion of the main body 41, and a large-diameter stop hole 43 communicates with the end thereof.
[0044]
In the tag 40 shown in FIG. 10C, the slit 42 extends from the outer peripheral end on one side of the main body 41 into the surface of the main body 41, but is curved in the surface of the main body 41. By being curved in this way, the slit 42 is engaged with the edge of the container 9, and the tag 40 can be more reliably locked.
[0045]
Each tag 40 shown in FIG. 11 has a wide slit 42 and is formed in a short length. A part of the slit 42 of the tag 40 in FIG. It has a round shape. Similarly, the slit 42 of the tag 40 shown in (b) is a triangle partly cut off by the outer peripheral end of the main body 41, and the slit 42 of the tag 40 shown in (c) is partly cut off by the outer peripheral end of the main body 41. It is a square. Even with such a wide and short slit 42, the tag 40 can be reliably locked to the container 9 by inserting the edge of the container.
[0046]
12 and 13 show still another form of the tag 40. In the tag 40, a cut line 60 is formed in the surface of the main body 41. The cut line 60 is a curved closed loop in which a part 60 a is opened, and a portion surrounded by the closed loop cut line 60 is a lip 61.
[0047]
The lip 61 has an open portion 60 a continuous with the main body 41, but the portion other than the open portion 60 a is separated from the main body 41 by a cut line 60. Therefore, as shown in FIG. 13, the lip 61 can be caused from the main body 41 through the cut line 60, and the edge portion of the container 9 can be sandwiched between the raised lip 61 and the main body 41.
[0048]
FIG. 14 shows the package 1 using the tag 40 having such a lip 61. At the time of extraction, the tag 40 can be locked to the edge of the container 9 by causing the lip 61 through the cut line 60 and sandwiching the edge of the container 9 between the lip 61 and the main body 41. In this embodiment, since the raised lip 61 is tapered, the container 9 can be smoothly locked.
[0049]
By sandwiching the edge of the container 9 between the lip 61 and the main body 41 in this way, the tag 40 is securely locked to the container 9, so that the tag 40 does not fall into the container 9 and hygienic extraction is performed. It can be carried out. Accordingly, it is not necessary to lengthen the hanging thread 20 to prevent the hanging thread 20 from falling into the container 9, and the hanging thread 20 can be shortened. In this case, the lip 21 is located inside the container 9 and the main body 41 is located outside the container 9, but the same applies to the opposite case.
[0050]
The cut line 60 of the tag 40 may be a closed loop with a part opened, and may be, for example, a rectangular closed loop cut line 60 as shown in FIG. It can be arbitrarily changed.
[0051]
【The invention's effect】
As described above, according to the present invention, when the side surface is folded, the bag body is flat in a normal state, so that it does not become bulky and can be easily stored in the outer bag. Moreover, since the upper surface and the lower surface overlap when the side surface is folded, the appearance is improved with a neat shape. Furthermore, since the capacity of the bag can be increased, the filling amount of the contents can be increased, and the contents can be smoothly moved in the bag, thereby improving the extraction efficiency.
[0052]
Further, the tag is physically coupled to the external member by further locking the locking portion formed on the tag to the external member such as a container. For this reason, the tag does not fall off from the outside, and the hanging thread and the tag do not drop. Therefore, it is not necessary to lengthen the hanging thread to prevent the sagging.
