Description

  The present invention relates to a drip bag that can be easily drip-type to obtain an extract of coffee, tea, green tea, herbal tea, or the like by hanging on an upper part of a container such as a cup.

  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.

  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.

  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).

  As shown in FIG. 7A, a coffee drip bag 100X described in Patent Document 1 is provided on a bag body 2 formed from a water-permeable filterable sheet and two outer surfaces of the bag body 2 facing each other. The bag body 2 is filled with an extraction material such as coffee powder. The latching member 10 has a central sticking part 11 stuck to the bag body 2, an arm part 13 formed so as to be raised from the bag body 2, and a latching piece 14. A pair of hooks 15 extending substantially horizontally is formed, and two pairs of bent lines L1 extending in the vertical direction of the bag body 2 are formed in total at the end of the hook member 15 at the center of the hook member 15. ing.

  Therefore, as a method of using this coffee drip bag 100X, (i) the perforation 4 at the upper end of the bag body is cut and the opening 3 is opened as shown in FIG. The lower part of the pair of latching pieces 14 is pinched to raise the latching piece 14 from the bag body 2, the folding line L1 at the upper part of the latching piece 14 is bent by hand, and the latching piece 14 is pulled in the opposite direction. As shown in d), the hooking piece 14 is hooked on the cup 200, and the hot water is poured into the wide opening 3. Alternatively, (ii) after the latching piece 14 is raised from the bag body 2, the pair of latching pieces 14 are pulled as they are in the opposite direction and latched on the cup 200 as shown in FIG. ), The bent line L1 at the top of the latching piece 14 is bent by hand and poured into the opening 3.

  Here, the folding of the broken line L1 is performed so that the hooking portion 15 is placed across the opening wall of the cup 200 when the hooking piece 14 is hooked on the cup 200. Even when the opening wall of 200 is thick, the coffee drip bag 100X can be stably set on the cup 200.

  However, when the coffee drip bag 100X is set on the cup 200 by the method (ii) of the above-described methods for using the coffee drip bag 100X, as shown in FIG. 7C, when the opening wall of the cup 200 is thick. After the coffee drip bag 100X is hooked on the cup 200, the fold line L1 is bent by hand as shown in FIG. 7 (d) and the hook 15 is placed on the opening wall of the cup 200. As shown in FIG. 2, the latching piece 14 may be lifted from the opening wall and detached from the cup 200.

  On the other hand, the present invention can be applied to a cup having a thick opening wall only by hooking the coffee drip bag on the cup 200 without manually folding the pair of folding lines L1 at the top of the hooking piece 14. The purpose is to enable the coffee drip bag to be hooked stably.

  In the present invention, when four folding lines extending upward from the lower end portion of the hook portion are formed in the region extending from one of the pair of left and right hook portions 15 to the other of the upper portion of the hook piece 14, the hook member of the hook portion 15 is formed. Even if the folding line L1 at the center side end portion is not bent by hand, the lower part of the pair of latching pieces 14 is pinched and pulled in the opposite direction, and the latching member 10 is latched on the cup. We found that the condition is stable.

That is, the present invention is a bag body formed from a water-permeable filterable sheet and having an opening at the upper end,
A drip bag having a hook member provided on two outer surfaces of the bag body facing each other,
The latching member can be caused from the center sticking part attached to the center of the bag body, the belt sticking part attached to the bag body along the opening of the bag body, and the bag body It has a hook piece that is not attached to the formed arm part and the bag body,
The lower end of the arm part is continuous with the center sticking part, the upper end part of the arm part is continuous with the latching piece,

Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.
FIG. 1 shows a method of using a coffee drip bag 100 in a state in which coffee powder 30 is filled in a drip bag 1 according to an embodiment of the present invention (a portion filled with coarse dots in the figure) and an opening 3 is closed. FIG. 4A is a plan view of the coffee drip bag 100 in an unopened state, and FIG. 4B opens the opening 3 of the bag body 2 and causes the latching piece 14 to be raised. FIG. 2C is a perspective view of a state in which the coffee drip bag 100 having the opening 3 opened is hung on the cup 200. The drip bag 1 can be filled with various extraction materials such as tea such as green tea, black tea, oolong tea, and herbal tea instead of the coffee powder 30.

  The drip bag 1 is formed of a water-permeable filterable sheet, and has a rectangular bag body 2 having an opening 3 at an upper end portion, and a latching member 10 provided on each of two opposing outer surfaces of the bag body 2. Have.

  As the water-permeable filterable sheet forming the bag body 2, a material that can be filled with a predetermined amount of extraction material and can be leached when the molten metal is poured is appropriately selected according to the extraction material and used. be able to. In general, as the sheet for leaching, for example, synthetic fibers such as polyester, nylon, polyethylene, polypropylene, vinylon, semi-synthetic fibers such as rayon, woven fabrics or nonwoven fabrics composed of natural fibers such as mulberry, Mitsumata alone or in combination, Papers such as mixed paper made of Manila hemp, wood pulp, polypropylene fiber, and tea bag base paper are known, and these can also be used in the present invention. In addition, when a drip bag is used for a coffee drip, the porosity of the fiber layer is adjusted when producing a water-permeable filterable sheet from a fiber material so that the coffee powder can have an appropriate steaming effect. As a result, the layer that is in direct contact with the coffee powder is sparse, the layer that is not in direct contact is `` dense '', and the layer that is in direct contact with the coffee powder is hydrophobic fiber. It is preferable to reduce the content of hydrophobic fibers in a layer that is not directly in contact with coffee powder (Japanese Patent No. 3675486).

  The bag body 2 is formed in a bag body by three-side seal portions 2 a, and a perforation 4 is provided at the upper end portion thereof as an easy-open line for forming the opening 3.

  On the other hand, the latching members 10 provided on the outer surfaces of the rectangular surfaces on the front and back sides of the bag body 2 are formed by punching a thin plate material in which paperboard, plastic sheets, etc. are laminated.

  The latching member 10 is attached to the bag body 2 in a belt shape along the center attaching portion 11 attached to the center portion of the bag body 2 and the opening 3 of the bag body 2, and the side of the bag body 2. A belt-like sticking portion 12 whose belt-like portion extends along the arm portion 13, an arm portion 13 formed so as to be raised from the bag body 2, and a latching piece 14 that is not stuck to the bag body 2. In FIG. 1A, a portion painted with fine dots is a portion of the latch member 10 that is adhered to the outer surface of the bag body 2 by heat fusion or adhesion.

  Here, the center sticking part 11 does not necessarily have to be stuck to the bag body 2 entirely, and in this embodiment, the area around the arm part 13 is stuck.

  The belt-like sticking part 12 has the whole surface of the belt-like part along the opening 3 stuck to the bag body 2, and the whole part of the belt-like part along the side of the bag body 2 is stuck to the bag body 2. Yes. In addition, the band-shaped portion along the opening 3 of the band-shaped sticking portion 12 is provided with a polygonal line L2 so that a large opening state is formed in the opening 3.

  The lower end of the arm part 13 is continuous with the central sticking part 11 and is stuck to the bag body 2. The arm portion 13 is not attached to the bag body 2 above the lower end, and the upper end portion of the arm portion 13 is continuous with the latching piece 14.

  The latching piece 14 is formed so as to surround the arm part 13 and the central sticking part 11, and is not stuck to the bag body 2. The hooking piece 14 is formed with a pair of left and right hooking parts 15 extending substantially horizontally from the continuous portion with the arm part 13 toward the side of the bag body. The hooking part 15 allows the hooking piece 14 to be cupped. The stability of the state of being hooked on the opening wall of 200 is improved.

  In the region extending from one to the other of the pair of left and right hooks 15, more specifically, in the region 16 in the vicinity of the continuous portion of the hooking piece 14 and the arm portion 13, four pieces extending upward from the lower end of the hooking portion 15. The polygonal line L1 is formed symmetrically. Here, the fact that the broken line L1 extends upward from the lower end portion of the hook portion 15 is not limited to strictly extending in the vertical direction of the bag body 2, but includes extending obliquely in the direction of the opening 3. Therefore, in the present embodiment, out of the four broken lines L1, the outer two broken lines L1a are formed in parallel to the vertical direction of the bag body 2, and the inner two folded lines L1b are formed at their lower ends. On the other hand, the upper end is close to the left and right central sides of the bag body. In addition, when the four polygonal lines L1 are viewed on each of the left and right sides, the outer polygonal line L1a and the inner polygonal line L1b are in positions where the lower ends thereof are substantially overlapped, and the upper ends of the inverted polygonal lines are opened. It is formed in a letter shape. In this way, the two bent lines L1 on each of the left and right sides are not formed in parallel, and the angle θ sandwiched between them is less than 180 °, just causing the pair of latching pieces 14 and pulling in the opposite direction, This is preferable in that mountain folds and valley folds are formed on the four broken lines L1. Moreover, when the lower end part of the broken line L1 is rounded at the part where the lower edge of the hook part 15 and the side part of the arm part 13 intersect, it should be outside in the left-right direction from the intersection point p of these extension lines. Is preferable, and it is more preferable to set the outer side in the left-right direction to be rounded.

  In the present invention, the number of broken lines L1 in the region from one to the other of the pair of left and right hooks 15 may be further added to the above four lines, but the extraordinary effect by adding a broken line It is preferable to use four.

  As a method of using the coffee drip bag 100, first, the bag body 2 is opened by cutting the upper end portion of the bag body 2 along the perforation 4 as shown in FIG. The lower end portion of the ten retaining pieces 14 is pulled in the opposite direction to cause the arm portion 13 and the retaining piece 14. These are caused more greatly, and the latching piece 14 is hung on the side wall of the cup 200 as shown in FIG. At this time, a mountain fold and a valley fold are naturally formed in the upper portion of the hooking piece 14 and in the vicinity of the continuous portion 16 with the arm portion 13 as shown in FIG. Even if the wall thickness of the opening wall of the cup 200 is thick, the latching piece 14 does not slide upward. Therefore, as before, it is not necessary to stabilize the latching state of the latching piece 14 by bending the bent line at the top of the latching piece 14 by hand.

  In the state where the coffee drip bag 100 of FIG. 1 (c) is hooked, the central sticking portion 11 facing the outer surface of the bag body 2 is pulled outward by the arm portion 13 to greatly open the bag body 2, and The belt-like sticking part 12 maintains the large opening shape of the opening part 3 of the bag body 2. Therefore, after the coffee drip bag 100 is hooked on the cup 200, the hot water can be easily poured from the opening 3 of the bag body 2, and a coffee extract can be obtained in the cup 200.

  In the above description, the coffee drip bag 100 is opened at the perforation 4 and then hooked on the cup 200. However, the method of using the drip bag 1 of the present invention is not limited to this, and the drip bag 1 May be poured into the drip bag 1 and then poured.

The present invention can take various aspects.
For example, the coffee drip bag 100B (drip bag 1B) of FIG. 2 has a U-shape surrounding the arm portion 13 with the central sticking portion 11 of the retaining member 10 as compared to the coffee drip bag 100 (drip bag 1) of FIG. And the entire surface is adhered to the bag body 2 to improve the adhesive strength of the hooking member 10 to the bag body 2.

  The coffee drip bag 100C in FIG. 3 is the same as the coffee drip bag 100B in FIG. 2, with the two inner fold lines L1b being parallel to the vertical direction of the bag body 2 and the two fold lines L1a on the left and right sides. , L1b is formed so that an inverted C shape is formed. Even if the folding line L1 is formed in this way, if the hooking piece 14 of the coffee drip bag 100C is hooked on the cup, the folding line L1 forms a mountain fold and a valley fold, and the hooking piece 14 is hooked on the cup. The state can be stabilized.

  The coffee drip bag 100D of FIG. 4 is the same as the coffee drip bag 100B of FIG. 2, but none of the four folding lines L1 is formed parallel to the vertical direction of the bag body 2, and two folding lines L1a on each of the left and right sides. , L1b is formed so that an inverted C shape is formed.

  The coffee drip bag 100E in FIG. 5 is the same as the coffee drip bag 100B in FIG. 2 except that the outer fold line L1a of the four fold lines L1 is shifted to the center side of the hook portion 15 and the two fold lines L1a on each of the left and right sides. The lower end of L1b is separated.

  The coffee drip bag 100F in FIG. 6 is the same as the coffee drip bag 100D in FIG. 4 except that the outer fold line L1a of the four fold lines L1 is shifted to the center side of the hook portion 15, and two fold lines L1a on the left and right sides are provided. The lower end of L1b is separated.

  In the present invention, the various aspects described above can be combined as appropriate. In any of the aspects, the four broken lines can be obtained by simply pulling the pair of latching pieces 14 in the opposite direction and latching them on the cup 200. L1 naturally forms a mountain fold and a valley fold on the upper portion of the hooking piece 14, and the hooking state of the drip bag or the coffee drip bag on the cup 200 can be stabilized.
