Abstract

<P>PROBLEM TO BE SOLVED: To provide a drip extraction bag which solves the issue that a conventional drip extraction bag made by a bag making system wherein a filter bag is formed by double-folding a sheet material with water permeability and filterability preliminarily attached and adhered with a support body and closing three sides is smaller in an area used for the support body than a filter bag shape and force for supporting the filter bag is small, causing the bag to be disposed deep in a cup for stable setting, accordingly the lower part of the filter bag is dipped in hot water in the cup to lower the drip performance. <P>SOLUTION: In the drip extraction bag, a support body integrated via a folding line part is placed on a front side and a back side of a double-folded sheet material. An upper opening of the filter bag is set on the center of the folding line part. The front side part and the back side part of the support body are opened upward and flattened. Right and left parts of the support body are folded downward to form bent side walls and both front and back end parts are folded downward to make end part walls to form the circumference of the support body and a downward directed box shape by the support body. Thus support force to support a high filter bag on the cup is constituted and the support body is enabled to be placed and set on the cup to make the filter bag a drip type wherein the lower part of the filter bag is not dipped into the surface of hot water in the cup. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention is a disposable drip type extraction bag such as regular coffee that is set in a drinking container and used to form a filtration bag having an opening on the upper side by a sheet material having water permeability. Attach a support made of cardboard or other waterproof material to the outer wall surface of the filter bag, place the filter bag on the drinking container such as a cup and place it on the support bag, and place coffee powder in the filter bag. Put drip extraction.

  A flat sheet material having a water flow filterability constituting the filtration bag is attached with a support such as cardboard that has been waterproofed in advance, and the sheet material is folded in half, and the three sides are sealed. There were bag-making drip extraction bags (Japanese Patent Laid-Open No. 2004-1785), Japanese Patent Laid-Open No. 2004-24700, Japanese Patent Laid-Open No. 2002-238767, and Japanese Utility Model Laid-Open No. 7-223. The filter bag is configured by sealing three sides that are larger than the support and have three sides extending outward from the support, thereby forming the overall shape of the drip extraction bag.

In comparison with this, in (Registered draft No. 3042292), (Japanese Patent Laid-Open No. 2000-279323), (Japanese Utility Model Laid-Open No. 57-145322) and (Japanese Patent Laid-Open No. 2004-711), the structure on the support side from the filter bag portion is different. It is a drip extraction bag mainly composed of a support body and a manufacturing process in which a filter bag is attached to the support body.

  In a filter bag constructed by attaching a waterproofing support to cardboard etc. in advance on a sheet material that has water-passability, folding the sheet material in half, and connecting the sheet materials on the three sides The production method of filling coffee powder into the bag can be simplified by reducing the production process of the drip extraction bag as a bag making method, but the cost can be reduced, but the support body is used to seal the three sides of the filter bag made of sheet material. However, it had to be smaller than this filter bag, and the following problems occurred in setting on the cup.

  In the case of (Japanese Patent Laid-Open No. 2004-1785), the upper opening of the filter bag is not opened widely, and when hot water is difficult to pour (Japanese Patent Laid-Open No. 2002-238767), the supporting force for supporting the filter bag on the cup is small. Cannot be secured sufficiently, and the supporting force is weak (Japanese Patent Laid-Open No. 2004-24700), and the supporting force is low in the supporting capacity of the filter bag and is not easy to set in the cup. The filter bag cannot be supported on the cup due to its small use area, and the lower part of the filter bag is set in a suspended state with the lower part of the filter bag positioned inside the cup. There were issues such as.

  Compared to this, in (JP 2004-1785), (JP 2002-238767), (JP 2004-24700), (JP 2004-711), etc., the support is configured to be larger than the filter bag. Since the body has a large area, the supporting force for supporting the filtration bag on the cup can be configured to be high, and the shape of the support can be freely configured so that the upper opening of the filtration bag can be enlarged, and the filtration bag is high on the cup. However, it is easy to position and hold it, so it is advantageous to ensure drip performance, but it uses a large area of the support and the manufacturing process that mainly constitutes the support makes the process complicated and expensive. It became.

  In the present invention, a sheet material having water permeability is preliminarily attached to the periphery of the sheet material, the support is integrally attached and adhered, the sheet material is folded in two, and the sheet material is outside the support. This is a bag-making method in which the sheet materials that are extended in close contact with each other and the three sides are closed to form a filtration bag, and the support is the same as the sheet material. As shown in FIG. 1, the filter bag is folded in two and is integrated with the filter bag positioned on the front side and the back side.

  The fold side of the filter bag constituted by folding in two is positioned upward, and the support body positioned on the front side and the back side with the fold as the center has an upper port for pouring hot water at the center of the center of the fold. Furthermore, the left and right sides of the upper opening of the support have a parallel fold line extending from the front support to the back support in the vertical direction. Each side is a side wall when the outside is formed into a box shape with a support and is long in the vertical direction. Both end portions of this side wall extend further in the vertical direction between the inner wall and the outer wall of the end wall. It has a side wall end portion that is folded into the side wall and fixed to the side wall.

  When the left and right sides of the support body with the crease side positioned upward are used as side walls, the upper opening provided in the center part of the support body is centered on the front and back folds that are the folds of the support body on the front side and the back side. The surface on the surrounding side is a top plate portion when a box shape is formed.

  When the crease side is positioned upward, the support has a width of the upper plate portion between the left and right side wall portions, and extends in the lower end direction on each of the front side and the back side to constitute an end wall. The protruding end portion is provided with two folds in the left-right direction, and becomes an outer wall of the end wall when the box shape is formed between the first fold and the second fold, and extends from the second fold to the lower end. The inner wall is folded into the inner wall, and a convex portion is provided at the center lower end of the inner wall. For fixing when the inner wall is folded inward, a T-shaped cut is made from the first fold to the upper plate. The projecting part is pushed out from below into the notch part provided with and is fixed by the presser part.

  This support is provided around the upper plate part, with the left and right side walls and the end walls of the lower end on the front side and the back side, the support on the front side and the back side is opened upward and the straight fold is extended, The upper plate portion is flattened, and the support body forms a rectangular and downward box shape in combination with the upper plate that is bent downward by the four sides of the left and right side walls and the two sides of the end wall.

  The side wall that extends long to the left and right of the upper opening is bent between the outer wall and the inner wall of the end wall by bending the part where both ends extend from the upper plate part, and the end wall is fixed. The fixed support has a box shape.

  The sheet material and the upper plate portion are attached to and integrally attached to the peripheral portion on the back side of the upper opening provided in the support.

  The upper opening provided at the center of the straight fold of the support is cut into the upper opening by cutting the sheet material part into the upper opening in the perimeter of the upper periphery of the sheet material in advance. Opened and used as the opening of the filter bag.

  A sheet of water-filterable sheet material is pasted on a cardboard paper support, and the sheet is folded in half and sealed on the other three sides, and filled with coffee powder. Due to the bag-making process, the production process can be simplified and the following advantages can be achieved while reducing costs.

  (Japanese Patent Laid-Open No. 2004-1785), (Publication Model No. 57-145322) and (Registration Model No. 304229) capture the mouth of the cup when it is set in the cup, and the entire structure of the support is maintained. For this reason, the detachment causes the drop off from the cup. However, in the present invention, the structure of the support is stable as long as it is placed on the mouth regardless of the caliber of the cup as in JP-A-2004-711. The shape of the support does not change depending on the size of the cup diameter, and the mouth shape is constant.

  (Japanese Patent Laid-Open No. 2004-24700) and (Kaikaihei 7-223) catching the mouth of the cup and forming and holding a filter bag shape, or (Japanese Patent Laid-Open No. 2002-238767) catching the top of the cup In the present invention, the overall shape of the box shape is configured by the support body in comparison with the type having a low strength of the stopper piece, so that the structural strength of the main body itself is increased, and the supporting force for supporting the filter bag on the cup is increased against deformation. .

  Even in the case of a small support area within the range of the filter bag shape, the support bag has a high support strength to form a box shape. Compared to the fact that the stability of the set is obtained in such a manner that the lower part of the substrate is immersed, in the present invention, since the structural strength of the support is high, it is easy to support the filter bag on the cup and the drip property can be secured.
