Description

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

  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 a few 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.

  Among them, as shown in FIG. 8, as having a simple configuration, a bag body 2 made of a water-permeable filterable sheet and a paper or the like attached to the two outer surfaces of the bag body 2 facing each other. There has been proposed a coffee drip bag 100 in which coffee powder is filled in a drip bag 1 composed of a hook member 10 and the hook member 10 has a specific shape (Patent Document 1).

Japanese Patent No. 3166151

  According to the coffee drip bag 100 of Patent Document 1, it can be easily attached to the cup 200 while the opening 3 is greatly widened during use. In particular, according to the aspect in which the reinforcing pieces 30 are provided along both side edges and the upper end opening of the bag main body, the opening shape of the opening 3 can be further increased and stabilized. Further, it can be manufactured at a lower cost than the conventional cup-on drip bag.

  However, in recent price competition, it has been demanded to further reduce the cost of the drip bags by reducing the constituent materials and reducing troubles during production.

  On the other hand, an object of this invention is to provide the drip bag which the opening part of a bag main body opens large, and the opening shape is stabilized at lower cost.

  As shown in FIG. 8, the inventor attaches a part of the retaining member 10 to the outer surfaces of the two opposing surfaces of the bag body and pulls the attached part in the opposite direction. In the drip bag that opens the bag body by the above, in order to save the constituent materials of the retaining member 10 and the reinforcing piece 30, the bag body 2 of the reinforcing pieces 30 along the both side edges and the upper end opening of the bag body 2. The portion 30a along both side edges is omitted, and only the portion 30b along the upper end opening of the bag body 2 is attached to the bag body 2. Even in this case, the opening shape of the bag body 2 is widely stabilized. In addition, by continuing the portion 30b along the upper end opening of the bag body 2 and the sticking portion 10a at the center of the latching member, each part constituting the latching member 10 is separated from the others. Can be eliminated, thereby Ability to eliminate positional deviation at the time of pasting destination of the portion constituting the stop member, found.

That is, the present invention is a drip bag having a bag body formed of a water-permeable filterable sheet and having an opening at the upper end portion, and a hook member provided on two outer surfaces of the bag body facing each other. And an upper sticking part in which the hooking member is stuck to the bag body along the opening of the bag body,
A central sticking part that extends from the upper sticking part to the bottom side of the bag body, and at least a part of the bottom part side is stuck to the bag main body,
It is an arm part formed on both right and left sides of the central sticking part, the lower end part of the arm part and the lower end part of the central sticking part are continuous, and the upper end part of the arm part is stuck to the bag body. The arm part formed so as to be able to be raised from the bag body,
Provided is a drip bag that is formed on the outer side of the arm part, is continuous with the upper end part of the arm part, and has a latching part that is not attached to the bag body.

  The present invention also provides a beverage drip bag in which the bag body of the drip bag is filled with an extraction material and the upper end portion of the bag body is closed.

  According to the drip bag of the present invention, when the hooking portion is hung on the cup, the arm portion continuous with the hooking portion is stuck to the two outer surfaces facing the bag body. Since the portions are pulled in directions opposite to each other, the bag main body is easily opened, and the upper sticking portion is formed along the opening of the bag main body, so that the opening shape of the bag main body is greatly stabilized.

  In addition, the upper end sticking portion is formed from the reinforcing pieces conventionally formed along the both side edge portions and the upper end opening portion of the bag main body so as to greatly stabilize the opening shape of the bag main body. This corresponds to the case where the reinforcing piece is omitted. Therefore, according to the drip bag of this invention, it becomes possible to reduce the constituent material of a latching member and to reduce manufacturing cost.

  Furthermore, according to the drip bag of the present invention, since the upper sticking portion, the central sticking portion, the arm portion, and the hooking portion constituting the hooking member are all continuous, the hooking member is stuck to the bag body. In doing so, it is possible to eliminate misalignment of each part. Therefore, it is possible to reduce the manufacturing cost even by reducing the occurrence of defective products.

  In addition, according to the drip bag of the present invention, it is obvious at a glance which part of the retaining member should be pulled to be hung on the cup when it is hung on the cup. Therefore, misuse of consumers can be prevented.

  Hereinafter, a drip bag of the present invention and a beverage drip bag in which the 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.

  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.

  A drip bag 1A used for the coffee drip bag 100A is made of a water-permeable filterable sheet material, and has a bag body 2 having an opening at the upper end, and outer surfaces of two opposing surfaces 2a and 2b of the bag body 2. 10A, respectively.

  For example, as shown in FIG. 2, such a drip bag 1 </ b> A has a pair of hooking members 10 </ b> A (the bottoms of which are opposed to each other with a gap therebetween) on a long belt-like water-permeable filterable sheet 21. A plurality of drip bag sheets 20 arranged at intervals are prepared, the sheet 20 is folded in two so that the edges in the longitudinal direction overlap each other, and welding and fusing are repeated in the short direction at intervals of the width of the bag body 2. be able to. In this case, the welded and cut portions are the side edges 2p and 2q of the bag body 2 (the portions with horizontal lines in FIG. 1A). Also, prior to the welding welding in the short direction, the edges in the longitudinal direction are welded together, and the coffee drip bag 100A is filled by filling the coffee powder one by one while repeating the welding welding in the short direction. Can be obtained. When manufacturing the coffee drip bag 100A, the water-permeable filterable sheet 21 may be previously provided with perforations 4 for opening. In addition, it may replace with the perforation 4 and may provide the weak part formed in the water-permeable filterable sheet 21 in the line form with the ultrasonic wave, the heat, etc. as an easy-open line.

  As the water-permeable filterable sheet 21 forming the bag body 2, various materials can be used that are capable of leaching coffee when filled with a predetermined amount of coffee powder and poured. 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, but from the point of disposal after use of the drip bag The water-permeable filterable sheet material preferably contains biodegradable fibers. Examples of the biodegradable fiber include polylactic acid, polybutylene succinate, and polyethylene succinate. In addition, in order to be able to impart an appropriate steaming effect to the coffee powder at the time of drip, when manufacturing a water-permeable filterable sheet from these fiber materials, it is in direct contact with the coffee powder by adjusting the porosity of the fiber layer. The layer that is in direct contact with the coffee powder is increased in the density of the multi-layered structure in which the layer to be in contact is “sparse” and the layer that is not in direct contact is “dense”. In the layer not in direct contact with the powder, it is preferable to reduce the content of hydrophobic fibers (Japanese Patent No. 3694486).

  On the other hand, the latching members 10A provided on the outer surfaces of the rectangular surfaces 2a and 2b on the front and back sides of the bag body 2 are composed of an upper sticking portion 11, a central sticking portion 12, an arm portion 13 and a hooking portion 14, respectively. It is formed by punching a thin plate-like material such as paperboard or plastic sheet, and is adhered to the bag body 2 at a predetermined site. In the latching member 10A of FIG. 1, the portion painted with fine dots is a portion adhered to the outer surface of the bag body 2 by heat fusion or adhesion, and the portion painted with coarse dots is not adhered. Part.

  The upper sticking part 11, the central sticking part 12, the arm part 13, and the hooking part 14 constituting the hooking member 10A are not separated from each other and are continuous. Therefore, when sticking the latching member 10A to the bag body 2, position shift of each part can be eliminated, and generation of defective products accompanying sticking of the latching member 10A can be reduced.

  The thin plate-like material that forms the retaining member 10A is also preferably made of a biodegradable material such as polylactic acid, polybutylene succinate, or polyethylene succinate from the point of disposal after use of the drip bag 1A.

  Of the constituent parts of the latching member 10 </ b> A, the upper sticking part 11 is a part formed in a belt shape along the opening 3 of the bag body 2, and is stuck on the upper part of the bag body 2. By providing the upper sticking part 11 in this way, when the coffee drip bag 100A is put on the cup 200 as shown in FIG. 1 (c), the opening shape of the opening 3 of the bag body 2 is greatly stabilized. be able to.

  The width L1 of the upper sticking portion 11 (the length of the upper sticking portion 11 in the width direction of the bag body 2) L1 is preferably equal to or less than the width L2 of the hooking portion 14, and particularly the opening width L1 ′ of the bag main body 2. 45% to 55% of is preferable. Thereby, when the coffee drip bag 100A is put on the cup 200, the opening shape of the opening 3 can be made substantially square, the pouring of the hot water into the opening 3 can be further facilitated, and the hooking member 10A The thin plate material necessary for formation can be minimized. That is, the opening 3 is widely opened even if the upper sticking portion 11 is formed wider and a fold line is formed if necessary, or a band-like portion is extended downward from both ends of the upper sticking portion. Further, the thin plate material necessary for forming the latching member 10A increases unnecessarily, and the manufacturing cost increases.

  The center sticking part 12 is a part extended from the upper sticking part 11 to the bottom side of the bag body 2, and is stuck to the bag body 2. In addition, in this invention, the center sticking part 12 should just be stuck to the bag main body at least at the part of the bottom part side, the sticking area | region with the bag main body of the upper sticking part 11, and center sticking Although it is not necessarily required to be continuous with the sticking area of the portion 12 with the bag body, in this embodiment, the sticking area from the upper end to the lower end of the central sticking portion 12 is made continuous, so that an inverted T shape is obtained. A shaped sticking region is formed.

  About the width | variety of the center sticking part 12, from the point which ensures opening of the bag main body 2, the largest width L3 of the center sticking part 12 is about 1/3-3/4 of opening width L1 'of the bag main body 2. It is preferable to do.

  A pair of arm portions 13 are formed on both the left and right sides of the central sticking portion 12, and each arm portion 13 is continuous with the lower end portion of the central sticking portion 12. Moreover, only the lower end part of the arm part 13 is stuck to the bag body 2, and the arm part 13 is not stuck to the bag body above that, and can be caused from the bag body 2.

  The hooking portion 14 is formed adjacent to the arm portion 13 so as to surround the outer side of the arm portion 13, and is continuous with the upper end portion of the arm portion 13. The hooking portion 14 is not attached to the bag body 2, and when the coffee drip bag 100A is hung on the cup 200, the hooking portion 14 is directly hooked on the side wall of the cup. By being formed on the outside of 13, a sufficient hanging width to the cup wall is ensured. For this reason, when the coffee drip bag 100A is hung on the cup 200, the bag body 2 does not tilt left and right (to the side edge of the bag body), and the opening 3 can be maintained upward when pouring. It becomes.

  As a method of using the coffee drip bag 100A, first, the bag body 2 is opened by cutting the upper end portion of the bag body 2 along the perforation 4, and a pair of pairs as shown by an arrow A in FIG. The lower end of the latching portion 14 is pulled to cause the arm portion 13 and the latching portion 14. These are caused more greatly, and the latching portion 14 is hung on the side wall 201 of the cup 200 as shown in FIG. After the coffee drip bag 100 </ b> A is hooked on the cup 200 in this way, the hot water is poured from the opening 3 of the bag body 2. Here, since the cut shape of each part of the coffee drip bag 100A is simple, the consumer can clearly understand the part to be caused at the time of using the coffee drip bag 100A without reading the instruction manual. be able to. Therefore, according to this coffee drip bag 100A, misuse of a consumer can be prevented.

  In addition, in the state where the coffee drip bag 100A is hung on the cup 200 in this way, the center attaching portion 12 attached to the opposing outer surface of the bag body 2 is opposite to each other as indicated by the arrow B by the arm portion 13. The bag body 2 is opened by being pulled in the direction. At this time, the opening 3 is opened with the width L <b> 1 of the upper attaching part 11 by attaching the upper attaching part 11 along the opening 3. Further, the hooking portion 14 presses the cup 200 as indicated by an arrow C while pulling the arm portion 13 outward. For this reason, the coffee drip bag 100A is attached to the cup 200 in a stable open state.

  In the above description, an example in which the coffee drip bag 100A is opened at the perforation 4 and then hooked on the cup 200 is shown, but the method of using the drip bag of the present invention is not limited to this, and the drip bag 1A is After the cup 200 is set, the coffee powder may be poured into the drip bag 1A and poured.

  The drip bag of the present invention can take various forms. For example, the coffee drip bag 100B (drip bag 1B) of FIG. 3A (a) has a stepped protrusion 11a on the upper end portion of the upper sticking portion 11 of the hook member 10B on the front and back of the bag body 2. It is provided so as to protrude alternately from the upper end of the bag body 2. In this case, the protruding portions 11a of the pair of latching members 10B protrude so as not to overlap each other. According to this coffee drip bag 100B, as shown in FIG. 3A (b), by separating the protruding portions 11a that protrude alternately at the time of opening from each other, the seal portion at the upper edge of the bag body 2 is peeled off and opened. To do. Therefore, the bag body 2 can be easily opened. Furthermore, since the protrusions 11a of the pair of latching members 10B are shaped so as not to overlap each other, when the pair of latching members 10 are punched from a single sheet-like material, as shown in FIG. By arranging the 11a sides to face each other, punching of the thin plate material can be minimized and punched without waste.

  The coffee drip bag 100C (drip bag 1C) of FIG. 4 has the same width L1 of the upper sticking portion 11 and the width L2 of the hooking portion 14 as the hooking member 10A of the coffee drip bag 100A of FIG. In addition, an outer adhesive portion 15 that is adjacent to the edge of the outer side of the arm portion 13 (opposite side of the central adhesive portion 12) and is adhered to the bag body 2 is provided. As in the case of the latching member 10C of the coffee drip bag 100C in FIG. 4, the width L1 of the upper sticking portion 11 and the width L2 of the latching portion 14 are aligned, and the outer shape of the latching member 10C is made substantially rectangular. It is possible to minimize the punching dust accompanying the formation of the stop member 10C. Further, by providing the outer sticking portion 15, a sticking region between the hooking member and the water-permeable filterable sheet is formed on both sides of the base portion of the arm portion 13, so that the load is concentrated on the lower end portion of the arm portion 13. Even so, the water-permeable filterable sheet can be prevented from being broken in the vicinity thereof. Furthermore, by providing the outer sticking part 15, when the drip bag 1C is opened, the bag 1C opens in a prismatic shape. Therefore, as shown in FIG.1 (c), the bag main body 2 can be constricted and it can prevent reducing the quantity which can be poured into the bag main body 2 at once. In addition, the outer sticking part 15 should just be provided adjacent to this arm part 13 in the outer side of the lower end part of the arm part 13, and does not need to extend to the upper end part of the arm part 13. FIG.

  The coffee drip bag 100D (drip bag 1D) of FIG. 5 extends the hooking portion 14 to the upper outside of the upper sticking portion 11 in the hooking member 10D with respect to the hooking member 10C of the coffee drip bag 100C of FIG. The upper sticking portion 11 is surrounded by the hooking portion 14. In general, a person tends to pick up the protruding end, but according to the latching member 10D, the upper end portion of the latching member 10D is not the upper sticking portion 11 but the latching portion 14. Since it is an extended part, a consumer can prevent picking up the right and left protruding ends of the upper sticking part 11 by mistake when using the coffee drip bag 100D.

  The coffee drip bag 100E (drip bag 1E) in FIG. 6 has a flat shape of the bag body 2 and the latching member 10E, respectively, more specifically, a substantially quarter circle shape. The attaching part 11, the central attaching part 12, the arm part 13, the outer attaching part 15, and the latching part 14 are formed. Thus, the design property is enhanced by making the planar shape of the bag body 2 into a fan shape. Moreover, since the extraction liquid is drip from the apex of a cone shape by making the lower end of the bag main body 2 into a cone shape, a coffee liquid with a higher concentration can be obtained.

  Moreover, in this coffee drip bag 100E, since the upper sticking part 11 is provided along the substantially whole side of the opening part of the bag main body 2, in order to enlarge the opening shape of the opening part 3, an upper sticking part A polygonal line M <b> 1 passing through the center in the width direction is formed from the upper end of the upper sticking portion 11 to the lower end of the central sticking portion 12. Thereby, as shown in FIG.6 (c), the vertex of the opening part 3 which becomes a top view rectangle is formed on the broken line M1. Therefore, the opening shape of the opening 3 can be enlarged and stabilized by the coffee drip bag 100E.

  In addition, in the present Example, the sticking part is not formed in the lower end part of the arm part 13, but the whole area is a non-sticking part with respect to a water-permeable filterable sheet. Thereby, permeation of hot water from the sticking part of the bag main body 2 and the latching member 10E to the latching member 10E can be prevented, and the opening shape of the bag main body 2 after pouring can be kept more beautiful.

  The coffee drip bag 100F (drip bag 1F) in FIG. 7 forms a fold line M2 in the outer adhering portion 15 in the coffee drip bag 100E in FIG. 6, and the lower end portion of the arm portion 13 is affixed to the bag body 2. It is what I wore. Thereby, the shape of the bag body 2 when the coffee drip bag 100F is hung on the cup 200 can be made substantially conical, and the opening shape of the bag body 2 can be kept larger.

  The drip bag of the present invention can further take various aspects, and the above-described modified aspects can be appropriately combined in various ways.

  Moreover, as an extraction material with which the drip bag of the present invention is filled, tea, green tea, Chinese herbal medicine or the like may be used instead of coffee powder. Thereby, various drink drip bags can be obtained.
