BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, examples of embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1, FIG. 2 and FIG. 3 show an extraction bag (hereinafter referred to as an extraction bag) 1 with a single-side hook according to a first embodiment of the present invention. The extraction bag 1 includes an extraction bag body 2 and a hook 4. The extraction bag body 2 is a bag-shaped member made of a filterable non-woven fabric, and contains the extraction object 3 such as coffee, tea, Japanese tea, etc., in the extraction container liquid such as a cup in an unopened state. Sunk into. Here, the hook 4 is formed of a substantially rectangular thin plate member, and is fixed to one side of the extraction bag body 2. The thin plate-like member may have a rectangular shape, or may have another shape, even if it is a partially deformed rectangle with rounded corners as shown in FIG. It doesn't matter. In the present embodiment, one hook 4 is provided in a state of being partially fixed to only one side of the extraction bag body 2.

[0026] The hook 4 is formed with two concave portions 9a and 9b which are concave on the lower side. As will be described in detail later, the recesses 9a and 9b are adapted to be engaged with the upper edge of the extraction container, and the extraction bag body 2 is held inside the extraction container by the hook 4. .

[0027] The concave portions 9a and 9b are formed by forming a concave slit (notch or the like) in the hook 4 and separating the inside during use. Like this Then, the inner region 9 c force of the recesses 9 a and 9 b remains on the support portion 7 side described later. As a result, the inner region 9c force is pressed against the inner wall of the extraction container, thus functioning as a stopper. In addition, the recesses 9a and 9b may be formed by cutting the hook 4 into a concave shape in advance, or a simple slit is formed in advance and the hook 9 is deformed by an external force during use. By expanding the slit, the deformed shape may be the recesses 9a and 9b. Further, as a method of forming the recesses 9a and 9b, for example, a perforation may be provided, and the recesses 9a and 9b may be generated by cutting along the perforations during use. .

[0028] The upper region A extending from at least the upper end to the vicinity of the center of the extraction bag body 2 is in a state in which it can be separated from the recesses 9a, 9b of the hook 4. Further, the hook 4 holds the vicinity of the center of the extraction bag body 2 in the vertical direction (meaning the vertical direction when placed in the extraction cup).

[0029] Further, the fixing region 8 between the hook 4 and the extraction bag body 2 has a longitudinal shape in which the vertical direction is short and the horizontal direction is long. In detail, the recess 9a is constituted by an inner edge 9a1 on the hook center side and an inner edge 9a2 on the hook outer frame side. Similarly, the recess 9b is constituted by two inner edges 9b1, 9b2.

The hook 4 further includes a support portion 7, a locking portion 5, and a grip portion 6. The support portion 7 extends downward continuously from one inner edge 9 a 1, 9 b 1 constituting each of the recesses 9 a, 9 b, and is fixed to the extraction bag body 2 in the fixing region 8 near the lower end. It is done. The locking portion 5 extends downward continuously from the other inner edges 9 a 2 and 9 b 2 constituting the recesses 9 a and 9 b, and comes into contact with the outer wall of the extraction container. The gripping part 6 is formed continuously below the locking part 5 so that the user can grip it by hand. A fold line 13 is formed at the boundary between the locking portion 5 and the gripping portion 6.

[0031] In the present embodiment, the locking portion 5 and the grip portion 6 are arranged on the peripheral edge of the hook 4 to constitute a so-called outer frame. Also, be sure to be surrounded by the outer frame of hook 4, The support part 7 is arranged inside thereof. The recesses 9 a and 9 b of the hook 4 are arranged on the upper side of the extraction bag body 2.

[0032] The material of the hook 4 serving as the thin plate member is not particularly limited, but natural or synthetic paper is usually suitable. Therefore, in order to fix it to the extraction bag body, it is appropriate to use a heat fusion method or an ultrasonic fusion method using an adhesive that is harmless to humans.

[0033] As shown in Figs. 2 and 4, the extraction bag body 2 is a so-called gusset-type bag having gussets 15 on the right side and the bottom. The upper and lower side portions 2A and the corner portions 2B of the extraction bag body 2 are sealed by, for example, heat fusion using an adhesive resin or ultrasonic fusion. In particular, the corner 2B seals the longitudinal ends of the gusset 15 so that no raw materials such as tea leaves remain on the upper and lower ends of the gusset 15. As shown in Fig. 2, the fold amount of gusset 15 is as shown in the cross section of (A_A), and the fold amount of gusset 15 b on one side to which hook 4 can be fixed is small. It is set so that the folding amount of the gusset 15a on the opposite surface side is increased. As a result, as shown in FIG. 8, when the extraction bag body 2 is shaken in the extraction container 14, compared to the gusset 15 b on one side (upper side of the drawing) to which the hook 4 is fixed, The gusset 15 b on the opposite side of the hook (the lower side of this drawing) widens greatly. Therefore, the side opposite to the hook of the extraction bag body 2 is inflated like a balloon so that the substance to be extracted can easily flow, and air and the extraction liquid 30 permeate into the inside from the hook surface side of the extraction bag body 2. It is like that.

[0034] Note that reference numeral 16 denotes a joint (seal) portion in the circumferential direction (body circumference direction) of the extraction bag body 2, and is integrated by heat fusion using an adhesive resin by ultrasonic fusion. ing.

[0035] When the extraction bag body 2 is manufactured, the extraction object is weighed and arranged on a strip-shaped sheet material that is continuous in the vertical direction, and the back side is wound around both sides of the sheet material. Seal the center joint 16 to make it cylindrical. After that, seal the upper and lower sides 2A and 2B, and then cut the upper and lower edges. 2 is manufactured. This is a so-called pillow set packaging method.

[0036] The filterable material forming the extraction bag body 2 includes, for example, pulp unbleached, bleached paper, cotton paper, natural or synthetic fiber woven or knitted fabric, non-woven fabric, Naiguchi Nya polyester water, etc. Examples include permeable materials. Also, synthetic fiber nonwoven fabrics or mixed nonwoven fabrics of paper and synthetic fibers, which are heat or ultrasonic sealable, can be used. Extract 3 is extracted from water, hot water, alcohol, etc., and its contents are not particularly limited. For example, oolong tea, green tea such as sencha, roasted tea, black tea, barley tea, brown rice tea, etc. Cereal tea, coffee powder, coffee grind, various herbal teas, herbal medicines and so on. The amount of the extract to be stored in the extraction bag body 2 varies depending on the type of the extract, the size of the extraction container, the purpose and preference, and can be arbitrarily determined.

[0037] The fixing region 8 between the hook 4 and the extraction bag body 2 is partially disposed on the lower end side of the support portion 7. As a result, the recesses 9 a and 9 b and the upper side of the support 7 are free without being fixed to the extraction bag body 2.

Therefore, as shown in FIG. 5, the locking portion 5 and the gripping portion 6 connected to the locking portion 5 are formed to be able to be raised from the support portion 7. That is, the outer frame side of the hook 4 can be pulled away from the inner support portion 7. Since the support portion 7 and the locking portion 5 are continuous via the recesses 9a and 9b, the support portion 7 and the locking portion 5 are twisted in the thickness direction at the recesses 9a and 9b. It has become.

[0039] As shown in FIG. 6, using the twist of the support portion 7 and the locking portion 5, the support portion 7 is brought into contact with the inner wall side of the extraction container and the locking portion 5 is brought into contact with the outer wall side of the extraction container. Thus, the recesses 9 a and 9 b are locked to the upper edge of the extraction container 14. As a result, the extraction bag body 2 is held inside the extraction container 14.

[0040] The gripping part 6 is bent in a direction away from the extraction bag body 2 by using a fold line 13. As a result, the gripping part 6 is separated from the outer wall of the extraction container 14, so that the entire extraction bag 1 can be handled safely and easily by gripping the gripping part 6 with a fingertip.

[0041] The recesses 9a and 9b are spaced at substantially symmetrical positions with respect to the center of the hook 4 in the width direction. Since it is provided with a gap, the hook 4 is stably fixed to the extraction container 14.

FIG. 7 shows a state in which the extraction liquid 30 is poured into the extraction container 14 after the extraction bag 1 is installed in the extraction container 14. When the extraction bag body 2 absorbs the extraction liquid 30 in the extraction container 14, the upper region A hangs down by its own weight. Accordingly, the upper region A is positioned below the recesses 9 a and 9 b of the hook 4 while being separated from the recesses 9 a and 9 b. As a result, the entire extraction bag body 2 is crushed in the extraction liquid 30.

[0043] Furthermore, the extraction bag body 2 is held by the support portion 7 in the vicinity of the center in the vertical direction of the extraction bag body 2 itself. At the same time as the upper region A hangs down, the extraction bag body 2 force gusset 1 5 is expanded in the extending direction. As a result, the internal space of the extraction bag body 2 is expanded, so that the extraction object 3 can float freely and the extraction efficiency can be increased.

FIG. 8 shows a state where the grip 6 is grasped with a fingertip and the hook 4 is removed from the extraction container 14. When the hook 4 is removed, the entire hook 4 becomes a suspension mechanism using the elastic deformation of the recesses 9a and 9b, and the extraction bag body 2 can be efficiently shaken upward and downward (see arrow Z). In addition, the fixing region 8 formed in the support portion 7 holds the extraction bag body 2 near the center in the vertical direction by a predetermined area, and therefore further expands in the direction in which the extraction bag body 2 force gusset 15 extends. So extraction efficiency can be increased. Furthermore, unlike the thread material, the hook 4 has a certain level of strength (rigidity), so it can be forced to swing left and right (see arrow Y) and back and forth (see arrow X) by the fingertip. Can do. Therefore, since the extraction bag body 2 can be forcibly shaken using the swing of the hook 4, the extraction concentration can be freely adjusted according to preference.

[0045] According to the extraction bag 1 of the present embodiment, the upper region A of the extraction bag main body 2 is separated from the recesses 9a and 9b and hangs down to the extract 30 side. The internal space of the extraction bag body 2 naturally expands, and the extraction efficiency can be increased. [0046] In particular, since the fixing area 8 force has a longitudinal shape with the horizontal side as the long side, the fixing area 8 does not get in the way when the upper area A hangs down. In other words, the range of the upper region A can be secured larger by reducing the vertical distance of the adhesion region 8. In addition, by making the fixing area 8 into a longitudinal shape, as shown in Fig. 8, it is possible to control the direction when swinging by hand.

[0047] Furthermore, since the recesses 9a and 9b are arranged on the upper side of the extraction bag body 2 (that is, on the upper region A side), the extraction bag body 2 is placed on the bottom side of the extraction container 14 It becomes possible to approach. As a result, it is possible to immerse the extraction bag body 2 even when the extraction liquid is small. In particular, since the extraction bag body 2 is held at the lower end side of the support portion 7, the extraction bag body 2 can be deeply submerged in the extraction liquid.

Next, an extraction bag 1 with a single-side hook according to a second embodiment of the present invention will be described with reference to FIG. 9 and FIG. In this extraction bag 1 with a single-sided hook, the same or similar members as those in the first embodiment already described are denoted by the same reference numerals, so that the description of the members is omitted, and the parts different from the first embodiment. Mainly explained.

[0049] The hook 4 of the extraction bag 1 is formed with two concave portions 9a and 9b which are concave on the lower side. The hook 4 includes a support part 7 and a locking part 5. The support portion 7 extends downward continuously from one inner edge 9 a 1, 9 b 1 constituting each recess 9 a, 9 b, and is fixed to the extraction bag body 2 in the fixing region 8 near the lower end. The A vertical fold line 7 a is formed in the support portion 7, and the concave portions 9 a and 9 b and the locking portion 5 are separated from the extraction bag body 2 by using the fold line, a. It is possible to bend and bend. As a result, the recesses 9a and 9b are arranged in a direction perpendicular to the extraction bag body 2, so that the recesses 9a and 9b can be easily placed on the upper edge of the extraction container 14 as shown in FIG. Can be engaged with

[0050] Upper region A extending from at least the upper end to the vicinity of the center in the extraction bag body 2 Can be separated from the recesses 9 a and 9 b of the hook 4. Further, the fixing region 8 at the lower end of the support portion 7 holds the vicinity of the center in the vertical direction of the extraction bag body 2. Therefore, when the extraction liquid 30 is poured into the extraction container 14, the upper region A of the extraction bag body 2 hangs down and is positioned below the recesses 9 a and 9 b. The extraction bag 1 of the second embodiment can also obtain the same effect as that of the first embodiment.

[0051] Next, an extraction bag 1 with a single-sided hook according to a third embodiment of the present invention will be described with reference to Figs. In this extraction bag 1 with a single-sided hook, the same or similar members as those in the first embodiment already described are denoted by the same reference numerals, and the description of the members is omitted. explain.

[0052] The locking portion 5 and the gripping portion 6 of the hook 4 are arranged in the peripheral region (the hatched portion in Fig. 11) to constitute a so-called outer frame. The inside of the outer frame (the part surrounded by the shaded area in Fig. 11) is the support part 7. The lower side of the support part 7 is fixed to the extraction bag body 2. The fixing region 8 occupies the lower half of the support portion 7.

The locking portion 5 and the gripping portion 6 connected to the locking portion 5 are formed so as to be able to be raised from the support portion 7. That is, in FIG. 11, the peripheral region can be separated from the support portion 7. Concave portions 9 a and 9 b are formed between the locking portion 6 and the support portion 7, and as shown in FIG. 12, the extraction bag 1 is extracted using the concave portions 9 a and 9 b. 1 4 can be locked.

It should be noted that the two recesses 9 a and 9 b are provided at a substantially symmetrical position with respect to the center 11 of the hook 4 (see the broken line in FIG. 11).

[0055] The locking portion 5 is formed with protrusions 1 2 ₃ and 1 2 b that protrude toward the center side (inward in the width direction). This protrusion 1 2 a, 1 2 b functions as a stopper and is stably locked to the upper edge of the extraction container. In other words, due to the cooperative action of the recesses 9a and 9b and the protrusions 1 2 3 and 1 2 b, the upper edge of the extraction container 14 may be thick or curved. The hook 4 can be locked stably. Can do.

[0056] The gripping part 6 connected to the locking part 5 is disposed below the hook 4, and a fold line 13 is formed at the boundary between these parts. As a result, the gripping portion 6 is bent and separated from the extraction container 14, so that safety in use is ensured. The folding line 13 is preferably a single continuous or intermittent groove so that it can be easily folded.

[0057] Further, the hook 4 is arranged so as to be biased to the upper side from the center of the extraction bag body 2. As a result, the extraction bag body 2 approaches the bottom side of the extraction container 14, so that the extraction bag body 2 can be deeply immersed in the extraction liquid.

Next, an extraction bag 1 with a single-sided hook according to a fourth embodiment of the present invention will be described with reference to FIGS. In this extraction bag 1 with a single-sided hook, the same or similar members as those in the first embodiment already described are denoted by the same reference numerals, and the description of the members is omitted. explain.

The extraction bag 1 includes an extraction bag body 2 and a hook 4. The hook 4 is formed with two concave portions 9 a and 9 b which are concave on the lower side. The recesses 9a and 9b are arranged on the lower region B side from the center to the lower end of the extraction bag body 2 in a state before use.

[0060] Further, in the fourth embodiment, in addition to the upper region A in the extraction bag body 2, the lower region B is also separable from the recesses 9a, 9b. The remaining region 9 c inside the recesses 9 a and 9 b is integrated with the locking part 5 or the gripping part 6 side.

[0061] The support portion 7 formed on the hook 4 includes an extended portion 7b that is inverted at the lower end side and extends further upward. The upper end side of the extension 7 b extends in the width direction, and this upper end is fixed near the center of the extraction bag body 2. As a result, the hook 4 holds the vicinity of the center of the extraction bag body 2 by using the fixing region 8 partially formed at the upper end of the extension portion 7 b in the support portion 7.

[0062] As shown in FIG. 14, the support portion is utilized by utilizing the twist of the support portion 7 and the locking portion 5. The recesses 9 a and 9 b are locked to the upper edge of the extraction container 14 by bringing 7 into contact with the inner wall side of the extraction container 14 and the locking part 5 against the outer wall side of the extraction container 14. As a result, the extraction bag body 2 is held inside the extraction container 14.

When the extraction liquid 30 is poured into the extraction container 14, the extension part 7 b of the support part 7 is elastically deformed by the weight of the extraction bag body 2, and is separated from the inner wall of the extraction container 14. Accordingly, the fixing region 8 at the upper end of the extension 7 b moves to the center side of the extraction container 14. As a result, the upper region A of the extraction bag body 2 also hangs down and is positioned below the recesses 9a and 9b. As a result, the entire extraction bag body 2 is immersed in the extraction liquid 30.

[0064] In the present embodiment, the fixing region 8 moves to the center due to the deformation of the extension 7b, so that the lower region B of the extraction bag body 2 can also be separated from the inner wall of the extraction container 14. As a result, the extraction bag body 2 is freely held in the vicinity of the center of the extraction container 14, so that the gusset 15 is expanded in the extending direction so that the internal space of the extraction bag body 2 can be further expanded. Become.

Next, an extraction bag 1 with a single-sided hook according to a fifth embodiment of the present invention will be described with reference to FIGS. In this extraction bag 1 with a single-sided hook, the same or similar members as those in the first embodiment already described are denoted by the same reference numerals, and the description of the members is omitted. explain.

As shown in FIG. 15, the hook 4 of the extraction bag 1 is formed with two concave portions 9 a and 9 b that are concave on the lower side.
