Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of a conventional coffee bag made by a method of bag-making in which a support formed of a pasteboard or the like, to which waterproofing is applied in advance, is provided on a sheet material with water-permeable filtering property and pasted on the sheet material while leaving an end on the periphery, the whole is double-folded at a fold penetrating in a lateral direction at a center of the support, and three ends, i.e., right and left ends of the sheet material and a lower end, are integrally closed, in which coffee powder is filled, wherein an area of the support being smaller than a filtering bag did not facilitate supporting the filtering bag in a position high above a cup without causing a lower part of the filtering bag to contact a surface of the hot water inside the cup. <P>SOLUTION: The integral support is arranged on a front side and a back side of the double-folded sheet material across the fold. An upper port of the filtering bag is arranged in the center of the fold. When the fold is stretched such that the upper port is made flat, the supports of the four sides, i.e., the right and left sides and front and rear sides of the upper port, are folded downward to form support arms. The filtering bag is supported from the front, rear, right and left directions by the four support arms and held in a high and stable position on the cup opening so that the lower part of the filtering bag is not immersed in the surface of the hot water inside the cup, achieving a coffee bag with high dripping property. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention is a disposable type drip type extraction bag such as regular coffee that is set on a drinking container and has a filter bag with an opening on the upper side made of a sheet material having a water-permeable filter bag. Then, a support body is constructed and attached with a member such as cardboard that is waterproofed to the filter bag, and the filter bag is supported and placed on the mouth portion of a drinking container such as a cup. Pour hot water into coffee powder and extract and drip.

  When constructing a filtration bag with sheet material having water permeability, attach a waterproof cardboard support to the sheet material in advance, attach the sheet material in half, and fold it together. In addition, there has been a bag-making drip extraction bag (Patent Application 2001-556143) and (Japanese Patent Application Laid-Open No. 2002). Basically, in this method, the filter bag side is generally larger than the support body in this method, and the three sides of the filter bag extending out from the support body by folding in half are It is characterized by a low cost due to the system in which the filter bag is sealed to form the entire shape of the drip extraction bag.

Compared to this, in (Japanese Utility Model Publication No. 57-145322) and (Japanese Patent Laid-Open No. 2004-711), the support side is configured to be larger than the filter bag, and the support side to which the filter bag is attached is mainly configured. It is a form, and since the support body can be made larger by the filter bag, there is an advantage that the filter bag can be firmly and firmly fixed and supported on the cup.

(Practical registration No. 1425541)
(JP 2004-711)

  A sheet of water-permeable filterable material is pasted on a support that has been waterproofed in advance, the sheet material is folded in half, and the three sides are closed to form a filter bag to form the overall shape of the coffee bag. Although the coffee bags of (Japanese Patent Application No. 2001-556143), (Japanese Patent Application Laid-Open No. 2002-238767), and (Japanese Utility Model Laid-Open No. 7-223) of the bag making system to be configured are advantageous in that they can be produced at low cost, the overall shape of the filtration bag Since the support body is located within the range, the flat area on the support body side is basically smaller than the entire flat area of the filter bag, which makes it a small support body. It is not suitable for construction, and the size of the filter bag increases when the area of the support is enlarged in order to obtain a large support force. When the filter bag becomes larger than the cup diameter, it can be set on the cup and used. There is a limit to the expansion of the area of the support body, so this type of type is to keep the filter bag shape formed and to prevent the lower part of the filter bag from being immersed in hot water and reducing the drip property There has been a problem that the support cannot sufficiently configure the supporting force to be positioned high on the cup.

  When forming a filtration bag, the sheet material is folded in half and the sides of the sheet material are sealed on three sides, and the support attached to the sheet material is the end of the filtration bag made of the sheet material. Therefore, if the width of the support to be set in the cup is widened, the filter bag becomes large and the body of the filter bag does not enter the cup caliber, and also enters the caliber of the small cup. Even when the body size of the filter bag is set, the left and right ends of the bag protrude from the body part to the left and right outwards below the filter bag, and if this part is a small-diameter cup, the width of the support should be reduced. Could not expand beyond a certain level.

  (Act. 7-223) is a support that focuses on catching the cup mouth portion with the retaining piece, and the force of the retaining piece catching the mouth portion of the cup is strong, but when set in the cup, the filter bag The setting method that supports and supports the entire weight at a high position and has a small hanging method causes hot water to be immersed in the lower part of the filter bag, resulting in a problem of low drip.

  (Japanese Patent Laid-Open No. 2002-238767), a locking part that catches the mouth of the cup to support the filter bag on the cup by the support, a support part that supports the cup, or a forming part that forms a filter bag shape, Since the necessary functions are composed of the support body, the area of the support body that can be used for the function of each part is reduced, and the function of holding the filter bag on the mouth of the cup cannot be obtained sufficiently. There were problems such as lack.

  In Japanese Patent Application No. 2001-556143, the half-folded side is positioned at the upper end, the front side and the back side of the support are elongated downwards, and both ends of the support are bent downward (practice registration No. 1). As shown in Fig. 1425541), it was formed in a downward U-shape and set in the mouth of the cup. Basically, in these methods, the entire cap can be grasped by the force of the catch piece. Is fixed, and there is a problem that the overall shape cannot be maintained when the number of sets and the locking pieces do not sufficiently capture the mouth of the cup (Japanese Patent Application No. 2001-556143). Since it has a fold that is folded in left and right in the center of the fold, it is necessary to stretch and fix this fold, so that both ends of the fold should be bent downward and this fold should be stretched and fixed. Without The labor and folding during bets, its effect is weak insufficient for this piece there is a problem in stability of the functions such as return to the original fixing the folded piece.

  Further, in order to solve this problem of (Japanese Patent Application No. 2001-556143), the support body at the left and right end portions of the folding line folded in half is elongated to form a U-shape downwardly, and this support It is possible to extend and fix the crease part at the same time as setting by setting the left and right side parts of the body downward and setting it in the cup, but basically this method is to make the cup caliber large and small like registration No. 142541 Accordingly, in order to respond by opening and subtracting the left and right sides of the support bent downward, a certain length is required for the left and right sides, but the length of the left and right sides of the support bent downward If it is short and the left and right ends that capture the cup mouth in the case of a large-diameter cup are large and the opening angle is steeply outward, the locking piece for catching the mouth of the cup provided at the tip of the left and right ends is The locking piece located in the center is The locking pieces on both the left and right sides catch the outer surface of the cup, and the locking pieces are pressed and fixed with a certain force from the outer wall side and the inner wall side of the cup mouth. It has the function of preventing the further bending in the bending direction where both left and right ends are bent downward by force, and maintaining the downward U-shaped shape formed by the entire support, and the length of both sides is If the cup caliber is not short enough, the opening angle at both ends becomes steep, and the locking piece that catches the outer wall surface of the cup does not catch the outer wall surface of the cup. Because the locking piece cannot be pinched between the inner wall side and the outer wall side of the cup mouth part and fixing force is not generated, the length of the left and right side parts when the left and right side parts of the support are bent downward is the cup mouth A certain length to the cup and the cup mouth The length of the latching piece sandwiched from the side and the outside is also necessary, and this bag making method has the maximum width in the left and right direction that the support can take in the size of the filtration bag within the range of the cup diameter, so this direction In order to form a U-shape by extending the support body long and bending both left and right sides downward, it was not possible to secure the right and left width of the support body.

  (Japanese Patent Laid-Open No. 2004-711), in that respect, the left and right folds of the cylindrical support are provided with folds for extending and fixing the folds, and the left and right folds are stretched and fixed in a half. It is easy to use because it is easy to set by simply placing it without the need to pinch the mouth of the cup by forming a boat-shaped support and looking on the cup, but it is fixed because the folding part extending the left and right folds is small There was a problem that the fixing force was low because the force was weak and the folding part was further bent in the folding direction and the shape of the entire boat shape could not be maintained.

  Compared to bag making methods such as (Japanese Patent Application No. 2001-556143) and (Japanese Patent Application Laid-Open No. 2002-238767) and (Japanese Utility Model Laid-Open No. 7-223), (Practical Registration No. 1425541) and (Japanese Patent Application Laid-Open No. 2004-711) are The manufacturing process is also expensive and has a problem of high cost, but the whole is greatly extended outward from the filter bag, and the support body is larger than the filter bag. The filter bag can be positioned to enhance the drip performance, and the support force supported on the cup can be strongly configured (Japanese Patent Application Laid-Open No. 2004-711). Even when set to the cup, the filter bag is opened with the support and the overall shape is fixed. Thus, it is possible to constitute an advantage that it is easy to set because it is a stationary method that can be set simply by placing it on the cup. ), Bend the left and right ends of the support body downward, catch the cup mouth part with the inner wall and the outer wall surface with the locking piece at the tip, and set the number of steps to fix the whole shape There was a problem that was necessary.
