[0002]
[Prior art]
Conventionally, the paper drip method has become widespread as a method of putting coffee that makes it easy to enjoy authentic coffee. In this paper drip method, usually several people (several cups) of coffee are extracted at a time.
[0003]
On the other hand, in recent years, the number of people who live alone has increased, and the number of members of a family has decreased due to the nuclear family and the decline in the birth rate. Therefore, instead of the conventional paper drip method, which is based on the extraction of several cups of coffee, a disposable wand drip coffee aimed at making it possible to easily extract a cup of coffee. Are on the market in various product forms.
[0004]
Above all, as having a simple configuration, a bag body made of a water-permeable filterable sheet containing coffee powder, and a paper attached to the side of the bag body in order to hang the bag body on a cup A coffee drip bag made up of a hooking member such as a hook has been proposed (see Patent Document 1).
[0005]

The coffee drip bag 100 includes a bag body 2 having a perforation 7 at the upper end, a hooking member 3 provided on the two outer surfaces of the bag main body 2, and an outer peripheral portion of the hooking member 3. The bag body 2 of the drip bag 1 composed of the provided reinforcing piece 9 is filled with coffee powder, and the opening at the upper end thereof is closed.
[0006]
The retaining member 3 is formed by making a score line in a thin plate material such as paper or plastic sheet. The latch member 3 includes a peripheral edge portion 4, an arm portion 5, and a tongue piece portion 6. The tongue piece portion 6 is attached to the outer surface of the bag body 2, and the lower portion of the tongue piece portion 6 and the arm portion 5 The lower part is continuous, and the upper end of the arm part 5 and the upper part of the peripheral edge part 4 are continuous. In the drawing, in the latch member 3, a portion painted with fine dots is a portion adhered to the bag body 2, and a portion painted with coarse dots is a portion not adhered to the bag body 2.
[0007]
When the coffee drip bag 100 is used, the upper end portion of the bag body 2 is cut along the perforation 7 to open the peripheral portion 4 as indicated by an arrow A (FIG. 7B), and the diameter of the cup 30 Then, the peripheral edge portion 4 is further raised and applied to the side wall 31 of the cup (FIG. 7C).
[0008]
As a result, the bag body 2 is pulled in the opposite direction in the direction of arrow B from the two faces facing each other by the arm portion 5, and is suspended from the center upper portion of the cup 30 with the opening 8 being greatly expanded. . And the reinforcement piece 9 prevents the front and back sheet | seat which comprises the bag main body 2 from bending, and the opening part 8 is closed. Moreover, the peripheral part 4 presses the outer surface of the cup side wall 31 in the arrow C direction. For this reason, the coffee drip bag 100 is fixed to the upper part of the cup 30 in a stable state.
[0009]
Thus, after the coffee drip bag 100 is set in the cup 30, delicious coffee can be easily obtained simply by pouring hot water from the opening 8 as indicated by the arrow. In addition, the coffee drip bag 100 after the coffee extraction can be easily discarded.

[Problems to be solved by the invention]
However, according to the coffee drip bag 100 described above, when the wall thickness of the opening of the cup 30 is thin, the wall 32 of the opening of the cup 30 is connected to the peripheral portion 4 and the arm as shown in FIG. Although it can be securely sandwiched between the portion 5 and the wall 32 of the opening of the cup 30 is thick as shown in FIG. There is a problem that the retaining member 3 is easily detached from the cup 30 as indicated by an arrow.
[0012]
Further, when coffee is extracted, as shown by arrows in FIG. 9, force is applied to the arm portion 5 and the bag body 2, and in particular, the lower corner portion 6 a of the tongue piece portion 6 affixed at the base portion of the arm portion 5. The load tends to concentrate on the sheet material. Therefore, when the sheet material is a material having a low mechanical strength such as a low-weight nonwoven fabric or a wet nonwoven fabric, the sheet material may be broken from the lower corner portion 6a of the tongue piece portion 6 in some cases.

[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a drip bag and a beverage drip bag in which a drip bag is filled with an extraction material such as coffee will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.
[0018]
Fig.1 (a) is a top view of one Example of coffee drip bag 100A which is one form of the drink drip bag of this invention, FIG.1 (b), (c) is explanatory drawing of the use condition, respectively. It is.
[0019]
In the coffee drip bag 100A, the drip bag 1A according to the embodiment of the present invention is filled with coffee powder, the opening at the upper end is closed, and the perforation 7 is provided at the upper end.
[0020]
The drip bag 1 </ b> A includes a bag body 2 made of a water-permeable filter sheet material, a latch member 3 provided on the outer surfaces of two opposite surfaces of the bag body 2, and a bag body 2 at the outer periphery of the latch member 3. It consists of the reinforcement piece 9 affixed on the outer surface.
[0021]
The bag body 2 has two rectangular surfaces 2a and 2b facing each other. For example, such a bag body 2 is formed by folding one rectangular sheet in half, using the folded mountain as the lower side of the rectangular surfaces 2a and 2b, and bonding or fusing both sides 2p and 2q of the rectangular surfaces 2a and 2b. (In FIG. 1A, the hatched portion of the horizontal line) can be formed by leaving the upper end as an opening.
[0022]
As the water-permeable filterable sheet material forming the bag body 2, various materials can be used that are capable of brewing coffee when filled with a predetermined amount of coffee powder and poured. For example, synthetic fibers such as polyester, nylon, polyethylene, polypropylene, vinylon, semi-synthetic fibers such as rayon, woven or non-woven fabrics made of natural fibers such as mulberry, mitsumata alone or composite fibers, Manila hemp, wood pulp, polypropylene fibers, etc. Papers such as mixed paper and tea bag base paper can be used. In addition, as a water-permeable filterable sheet material, in terms of taste, fragrance, flavor, and extraction time, the first layer is polyester, the second layer is a mixed paper of regular polyester and low-melting polyester, and the third layer is polypropylene. A sheet material having a three-layer structure made of a melt-blown nonwoven fabric made of ultrafine fibers is preferable, while it is preferably made of a biodegradable material from the viewpoint of disposal after use of the coffee drip bag. Examples of the biodegradable material include polylactic acid, polybutylene succinate, and polyethylene succinate.
[0023]
The latch member 3 is provided on the outer surfaces of the rectangular surfaces 2a and 2b on the front and back of the bag body 2 in order to put the bag body 2 on the cup 30. In the latching member 3 of FIG. 1A, the portion painted with fine dots is a portion adhered to the outer surface of the bag body 2, and the portion painted with coarse dots is a portion not adhered. . The retaining member 3 is made of a thin plate material such as paper or a plastic sheet. This thin plate material is also preferably formed from a biodegradable material such as polylactic acid, polybutylene succinate, polyethylene succinate and the like.
[0024]
The latching member 3 is composed of a sticking part 11, an arm part 5, and a latching piece 12, which are formed by punching one sheet-like material.
[0025]
Here, the arm portion 5 has a lower end continuous with the sticking portion 11 and an upper end continuous with the hooking piece 12 so as to be raised from the bag body 2. In addition, the lower end portion of the arm portion 5 that is continuous with the sticking portion 11 is located in the center portion in the width direction of the hooking member 3.
[0026]
The almost entire surface of the attaching part 11 is attached to the outer surface of the bag body 2, and this attaching part has a concave shape surrounding the lower end of the arm part 5 from below and from both sides.
[0027]
The latching piece 12 is formed over the entire outer periphery of the latching member 3 and is continuous with the center of the upper end of the arm unit 5. Moreover, the latching piece 12 has the hook part 13 which was cut | disconnected by the line L1 from the upper end of the arm part 5, and was extended in the substantially horizontal direction at the upper part both sides. A fold line L2 is formed at the end of the hook portion 13 on the center side of the hook member 3, and a fold line L3 is formed on the extension line of the fold line L2 below the hook piece 12.
[0028]
The reinforcing piece 9 is in a position in contact with the hooking member 3 above and on both sides of the hooking member 3, and is attached to the outer surface of the bag body 2. When the reinforcing piece 9 is formed at a position in contact with the latching member 3 in this way, the latching member 3 can be easily formed by punching one sheet-like material at a low cost by suppressing waste of the sheet-like material. It is preferable because the reinforcing piece 9 can be formed at the same time. Further, the reinforcing piece 9 has a belt-like portion along the opening of the bag body 2, and a folding line L <b> 4 for folding the belt-like portion into a U shape is formed in the belt-like portion.
[0029]
There are no particular limitations on the size of the retaining member 3 and the reinforcing piece 9, but when the coffee drip bag 100A is put on the cup 30 (see FIG. 1 (c)), if the bag is too small, the shape of the bag body 2 is stable. For example, when the height H1 of the bag body 2 is 70 to 100 mm and the width W1 is 65 to 85 mm, the height H2 of the hook member 3 and the reinforcing piece 9 is 35 to 85 mm, The width W2 is preferably about 35 to 75 mm.
[0030]
As a method for extracting coffee using the coffee drip bag 100A, first, the bag body 2 is opened by cutting the upper end of the bag body 2 along the perforation 7, and is shown in FIG. As described above, the arm portion 5 and the latching piece 12 are caused. Next, as shown in FIG. 1 (c), the arm portion 5 and the latching piece 12 are further raised in accordance with the diameter of the opening of the cup 30, and the latching piece 12 is hung on the side wall 31 of the cup. Is folded along the polygonal lines L2 and L3. Thus, after setting the coffee drip bag 100A in the cup 30, the hot water is poured from the opening 8 of the bag body 2.
[0031]
By setting the coffee drip bag 100 </ b> A in the cup 30 in this way, the hook 13 is hooked so that the hook 13 is placed on the wall 32 of the opening of the cup 30, and the hook 3 is extremely stable on the cup 30. It is hooked. At this time, the bag body 2 is pulled by the arm portion 5 from the two faces facing each other in the direction of arrow B in opposite directions, and the opening 8 is greatly widened. Moreover, this opening shape is favorably maintained by the reinforcing piece 9 having the broken line L4, and the rectangular surfaces 2a and 2b on the front and back of the bag body 2 are prevented from being bent and the opening 8 is closed. In particular, as shown in FIG. 2, the band-shaped portion 9a of the reinforcing piece 9 provided along the opening 8 of the bag body 2 is bent at a fold line L4, and the band-shaped portion 9a is formed into a U-shape. Even when the diameter of the opening 30 is small, the opening 8 of the bag body 2 can be in an expanded state.
[0032]
On the other hand, as shown in FIG. 10, in the conventional coffee drip bag 100 in which the reinforcing piece 9 does not have such a broken line, when the diameter of the opening of the cup 30 is small, the opening of the bag body 2 is opened. The opening of the part 8 becomes narrow.
[0033]
Thus, according to the coffee drip bag 100A, the coffee drip bag 100A can be easily set in the cup 30 in an extremely stable state regardless of whether the wall of the opening of the cup 30 is thick or thin. Further, the coffee drip bag 100A can be set in the cup 30 in a state where the opening 8 of the bag body 2 is greatly opened regardless of the diameter of the opening of the cup 30. Therefore, pouring hot water during coffee extraction becomes easy.
[0034]
Furthermore, according to this coffee drip bag 100A, the lower end part of the arm part 5 continuous with the sticking part 11 is located in the center part in the width direction of the hooking member 3, and the sticking part 11 has the outside of the bag body 2. Since the part pasted on the surface has a concave shape so as to surround the lower end of the arm part 5 from below and from both sides, it is possible to extract coffee as compared to the coffee drip bag 100 of FIG. Sometimes the load applied to the sheet material of the lower corner portion 11a of the sticking portion 11 is greatly reduced. Therefore, the sheet material of the bag body 2 is prevented from being broken during coffee extraction.
[0035]
In the above description, an example in which the coffee drip bag 100A is set in the cup 30 after opening the coffee drip bag 100A with the perforation 7 is shown, but the method of using the coffee drip bag 100A of the present invention is not limited to this. Alternatively, the coffee drip bag 100A may be opened after the coffee drip bag 100A is set in the cup 30.
[0036]
Fig.3 (a) is a top view of the coffee drip bag 100B of the different aspect of this invention, FIG.3 (b), (c) is explanatory drawing of the use condition, respectively. In FIG. 3A as well, a portion painted with fine dots is a portion attached to the outer surface of the bag body 2, and a portion painted with coarse dots is a portion not attached.
[0037]
This coffee drip bag 100B has a bag body 2 formed in a large size so as to be suitable for a drip for several cups instead of a cup of coffee. As shown in FIG. A gusset 14 formed by folding the sheet material is formed.
[0038]
Further, in this coffee drip bag 100B, when the bag body 2 is hooked to the coffee server 35 or the like, the hook body 3 is made to prevent the bag body 2 from being immersed in the extract accumulated in the coffee server 35. The positions of the lower side and the lower side of the bag body 2 are substantially aligned.
[0039]
In addition, the hooking portion 13 of the latching piece 12 is not defined by both the upper end side portions of the arm portion 5 and the cut line, but is defined by the upper end portion of the sticking portion 11 and the cut line L5. Thereby, compared with the coffee drip bag 100A of FIG. 1, the area ratio of the sticking part 11 increases, and the joining strength of the bag main body 2 and the latching member 3 improves. Further, as shown in FIGS. 5A and 5B, by appropriately increasing the length W3 of the cut line L5, the hook portion 13 is not bent at the broken lines L2 and L3 (see FIG. 1A). However, the latching piece 12 can be stably latched with respect to the coffee server 35 or cup etc. with which the wall of an opening part is thick.
[0040]
The preferable value of the length W3 of the cut line L5 varies depending on the wall thickness of the opening of the coffee server 35 or the cup or the like that holds the coffee drip bag 100B. The length W3 of the lead-in line L5 is preferably 6 to 20 mm.
[0041]
FIG. 6A is a plan view of a coffee drip bag 100C of still another aspect of the present invention, and FIGS. 6B and 6C are explanatory views of the usage state thereof.
[0042]
The coffee drip bag 100C shown in FIG. 6 is formed on the upper outer peripheral portion of the arm portion 5 without forming the hooking piece 12 over the entire outer peripheral portion of the hooking member 3, and the lower portion of the arm portion 5 is bifurcated. Each of the lower end portions is made to be continuous with the sticking portion 11, and the sticking portion 11 is stuck to the outer surface of the bag body 2 at a portion surrounding the lower and lower sides of the lower end portion. Also in this aspect, since the affixing part 11 is affixed to the outer surface of the bag body 2 at the part surrounding the lower end of the arm part 5 continuous with the affixation part 11 from below and from both sides, when extracting coffee The load applied to the sheet material of the lower corner portion 11a of the sticking portion 11 can be greatly relaxed, and the sheet material of the bag body 2 can be prevented from being broken when coffee is extracted.
[0043]
Note that the upper portion 11 b of the triangular sticking portion 11 sandwiched between the two arm portions 5 is not stuck to the bag body 2. Thus, in the present invention, it is not always necessary to stick the entire surface of the sticking portion 11 to the outer surface of the bag body 2.
[0044]
Further, the coffee drip bag 100C is formed with a curved cut line L5 that divides the upper portion of the retaining piece 12 and the upper end of the sticking portion 11, thereby forming the hook portion 13. Therefore, as shown in FIG. 6C, when the coffee drip bag 100C is also set in the cup 30, the hooking portion 13 of the hooking piece 12 is hooked so as to be placed on the wall 32 of the opening of the cup 30, The stop member 3 is hooked on the cup 30 very stably.
[0045]
Furthermore, the upper end of the latching piece 12 protrudes, so that the latching piece 12 and the arm portion 5 are combined to form a humanoid shape, which is innovative in design. In the invention, each shape of the latching piece 12, the arm part 5, the sticking part 11, and the reinforcing piece 9 is hooked on the latching piece 12 so as to ensure stability when hooked on the cup 30. In addition, in order to prevent the sheet material from being broken due to the concentration of load during extraction, as long as the attachment portion of the attachment portion 11 that is continuous with the lower end portion of the arm portion 5 has a specific shape, the design is limited. There is no.
[0046]
In addition, the present invention can take various forms.
[0047]
For example, the perforation 7 at the upper end of the bag body 2 of the coffee drip bags 100A, 100B, and 100C described above is provided to facilitate the opening of this portion. May be sealed by thermal bonding to such an extent that can be easily peeled off.
[0048]
Moreover, as an extraction raw material with which the drip bag of the present invention is filled, tea leaves such as black tea and green tea, Chinese herbal medicine, etc. may be used instead of coffee powder, and various beverage drip bags can be obtained thereby.
[0049]
【The invention's effect】
The drip bag of the present invention, or a beverage drip bag filled with an extraction raw material, is extremely easy to set in a cup regardless of the wall thickness of the opening of the cup from thin to thick. The shape after setting is also stable. Moreover, regardless of the size of the opening diameter of the cup, the opening of the bag body can be greatly opened, so that pouring is easy.
[0050]
Furthermore, at the time of extraction, the sheet material forming the drip bag can be prevented from being broken due to the concentration of the load.
