BACKGROUND OF THE INVENTION
The present invention relates to a drip bag used for extraction of regular coffee or the like, and more particularly to a drip bag including a bag-like filter and a holder that supports the filter on a cup.
[0002]
[Prior art]
A drip bag is formed by folding a cardboard holder along one side of a rectangular bag to form a side fold, and a pair of holder halves with the side folds as connecting portions are connected to both sides of the filter. There is something fixed to.
In addition to a pair of locking portions formed by cutting and raising part of the left and right holder halves, this drip bag is provided with another locking portion in the region including the side bent portion of the holder, for a total of three The locking part is locked to the edge of the cup, and the filter is supported at a position corresponding to the opening of the cup. And hot water is poured from the opening formed in the upper end part of a filter, and regular coffee etc. are extracted.
[0003]
However, since the force of pulling the filter downward is generated by the weight of the hot water poured into the filter, there is a risk that the opening of the filter may be narrowed by pulling the holder halves closer to each other.
Further, the holder halves move toward each other, and the distance between the holder halves becomes narrow, so that the drip bag support becomes unstable. For this reason, the center of gravity of the drip bag is tilted by the weight of the hot water, which may cause the filter to tilt.
Therefore, the region including the upper end of the side bent portion of the holder is bent to the filter side to form a reinforcing portion, and even if hot water is poured into the filter with this reinforcing portion, the holder halves do not move in a direction approaching each other. A drip bag is considered.
[0004]
[Problems to be solved by the invention]
However, in order to form the reinforcing portion, the side bent portion extending in the vertical direction of the holder must be pushed down, and the filter side, that is, the pair of holder halves must be folded toward the regions facing each other. Therefore, the resistance at the time of bending is large, and the work of forming the reinforcing portion is troublesome.
Furthermore, since it is difficult to perform an operation for forming a reinforcing portion that bends the upper end portion of the holder, it is not easy to form the reinforcing portion in an accurate left-right symmetrical shape. If the reinforcing part cannot be formed in an accurate left-right symmetrical shape, the function as the reinforcing part for preventing the holder halves from approaching each other cannot be performed reliably.
[0005]
The present invention has been made in view of the above-described problems, and can easily form a reinforcing portion that prevents the holder halves from approaching each other when hot water is poured into the filter, and the formed reinforcing portion is accurate.

The filter 3 is formed by folding a rectangular sheet in half, and the other three sides other than the right side 5 formed by a folding curve are heat sealed. That is, the left side 7, the upper side 9, and the lower side 11 are formed by heat sealing. A perforation 12 is provided along the upper side 9 at the upper end of the filter 3. Further, the filter 3 is filled with regular coffee H as an extractable.
[0014]
A cardboard holder 13 is fixed to the filter 3 via an adhesive portion 15. It is comprised by a pair of holder half 19 which becomes line symmetrical about the holder 13 side edge bending part 17. The holder 13 is fixed to the filter 3 so that the side bent portion 17 is along the right side 5 of the filter 3, and the side bent portion 17 is bent along the right side 5. The holder half 19 extends along both side surfaces of the filter 3.
[0015]
The pair of holder halves 19 are respectively provided with locking portions 21. The locking portion 21 is formed by making a cut 23 in the holder half 19. Further, a notch 25 is formed on the left and right sides of the side bent portion 17 at the lower end of the holder half 19, and a locking portion 27 is provided at a portion sandwiched between the pair of notches 25.
[0016]
A round hole 29 as a dividing portion is formed at the upper end portion of the holder 13, and this round hole 29 is formed by punching a region including a part of the side bent portion 17. Accordingly, the side bent portion 17 is divided in the middle by the round hole 29.
The pair of holder halves 19 are respectively formed with reinforcing bent portions 31, and the pair of reinforcing bent portions 31 are formed so as to be symmetrical with respect to the side bent portion 17. The pair of reinforcing bent portions 31 extend obliquely toward the upper end portion of the holder half 19, and the lower ends of the pair of reinforcing bent portions 31 are connected to the round holes 29. Further, the virtual intersection P of the pair of reinforcing bent portions 31 is on the extension line of the side bent portion 17 and is located in the round hole 29. A perforation 33 is formed in the side bent portion 17 and the pair of reinforcing bent portions 31.
A cutout 35 is formed at the upper end of the holder half 19, and the pair of cutouts 35 are continuous with the reinforcing bent portion 31.
[0017]
Next, the usage method of this drip bag 1 is demonstrated.
As shown in FIG. 3, the upper end of the filter 3 is broken along the perforation 12 to form an opening at the upper end of the filter 3. And the latching | locking part 21 of the holder 13 is caused.
Further, the reinforcing bent portion 31 is bent to the filter 3 side, that is, the opposing region side of the pair of holder halves 19 to form the reinforcing portion 39. The reinforcing portion 39 serves to restrict the portions of the pair of holder halves 19 along the filter 3 from approaching each other and maintain a certain distance.
[0018]
As described above, the round hole 29 divides the side bent portion 17, and the virtual intersection P of the pair of reinforcing bent portions 31 is on the extension line of the side bent portion 17 and is located in the round hole 29. Therefore, when the reinforcing bent portion 31 is bent to the filter 3 side, the side bent portion 17 does not need to be bent down. That is, the side bent portion 17 is missing at the portion where the round hole 29 is formed, and the portion that is bent toward the filter side of the conventional holder is located at the missing portion of the side bent portion 17. There is no need to bend the bent portion 17 by pushing it down, and there is almost no resistance when bending. Therefore, the region surrounded by the reinforcing bent portion 31 at the upper end portion of the holder 13 can be bent to the side of the filter 3, that is, the region side where the pair of holder halves 19 face each other with a very slight force. Can be easily formed. Further, the perforation 33 and the notch 35 on the side bent portion 17 and the reinforcing bent portion 31 have a function of reducing resistance when the region surrounded by the reinforcing bent portion 31 at the upper end portion of the holder 13 is bent. Demonstrate.
[0019]
In addition, since the region surrounded by the reinforcing bent portion 31 can be bent to the opposite region side of the holder half 19 with a very slight force, it is formed so as to be symmetrical with respect to the side bent portion 17. It is possible to accurately fold the reinforcing bending portion 31. Accordingly, the reinforcing portion 39 can be formed in an accurate line symmetrical shape with the side bent portion 17 as the center. Therefore, it is possible to reliably fulfill the role of restricting the portions of the pair of holder halves 19 along the filter 3 from approaching each other and maintaining a certain distance.
[0020]
Next, the locking portions 21 and 27 are locked to the edge of the cup C, the lower side 11 of the filter 3 is on the lower side, and the drip bag 1 is supported by the cup C. The lower side 11 of the filter 3 is the opening of the cup C. It enters a state of entering Ca.
And hot water is poured from the opening 37 of the filter 3, regular coffee H is extracted, and the hot water containing an extraction component oozes out from the filter 3 and is stored in the cup C.
[0021]
As described above, since the reinforcing portion 39 is formed in an accurate line-symmetric shape with the side bent portion 17 as the center, even if hot water is poured into the opening 37 of the filter 3, it follows the filter 3 of the pair of holder halves 19. It is possible to reliably restrict the portions from approaching each other and prevent the opening 37 from being inadvertently closed.
[0022]
Next, a method for manufacturing the drip bag 1 will be described.
This drip bag 1 can be filled with so-called bags, which can be filled with an object to be filled while continuously forming the drip bag.
As shown in FIG. 6, the holder 13 is fixed to the sheet material 3 a constituting the filter 3 at a predetermined interval.
[0023]
Then, the sheet material 3a is folded in half by the bag making and filling machine to form the right side 5, and the end on the side facing the right side 5 is welded by the seal head S in the vertical direction to form the left side 7. Further, the lateral direction of the sheet material 3a is sealed and cut by the apparatus to form the lower side 11, and then the regular coffee H is filled from the nozzle N into the space surrounded by the right side 5, the left side 7 and the lower side 11. Next, as described above, the lateral direction of the sheet material 3a is sealed and cut, that is, the upper side 9 and the perforation 12 are formed, the drip bag 1 is separated from the sheet material 3a, and the next (upper) drip bag 1 A lower side 11 is formed.

Reference numeral 53 indicates a cut as a dividing portion, and the cut 53 divides the side bent portion 17 at an intermediate portion. This cut 53 extends toward the tip of the pair of holder halves 19 and is inclined so as to rise upward toward the upper end of the holder halves 19.
[0025]
Reference numeral 55 denotes a pair of reinforcing bent portions, and the pair of reinforcing bent portions 55 are formed so as to be symmetrical about the side bent portion 17. One end of the pair of reinforcing bent portions 55 is connected to both end portions of the cut 53. The pair of reinforcing bent portions 55 extend straight in the direction orthogonal to the upper end portion of the holder half 19, and the other end of the reinforcing bent portion 55 reaches the upper end portions of the pair of holder half 19.
[0026]
Next, the usage method of this drip bag 51 is demonstrated.
As shown in FIG. 9, the upper end of the filter 3 is broken along the perforation 12 to form an opening at the upper end of the filter 3. And the latching | locking part 21 of the holder 13 is caused.
Further, the reinforcing bent portion 55 is bent toward the filter 3 side, that is, the region side where the pair of holder halves 19 face each other, thereby forming the reinforcing portion 57. The reinforcing portion 57 is constituted by a portion surrounded by the notch 53 and the reinforcing bending portion 55. The reinforcing portion 57 serves to restrict the portions of the pair of holder halves 19 along the filter 3 from approaching each other and maintain a certain distance.
[0027]
As described above, since the cut 53 divides the side bent portion 17, it is not necessary to bend the side bent portion 17 so as to push it down, and there is almost no resistance at the time of bending. Therefore, the reinforcing portion 57 can be easily formed simply by lightly pushing the portion surrounded by the notch 53 and the reinforcing bent portion 55 toward the filter 3 side. Further, the perforation 33 on the side bent portion 17 and the reinforcing bent portion 55 reduces resistance when a portion surrounded by the cut 53 and the reinforcing bent portion 55 is pushed into the filter 3 side.
[0028]
Moreover, since the reinforcement part 57 can be formed in the exact symmetrical shape centering | focusing on the side bend part 17, the part along the filter 3 of a pair of holder half 19 is controlled, and a fixed distance is maintained. It is possible to reliably fulfill the role.
[0029]
Next, in the same manner as described in the first embodiment, the locking portions 21 and 27 are locked to the edge of the cup C as shown in FIG. The lower side 11 of the filter 3 enters the opening Ca of the cup C.
And hot water is poured from the opening 37 of the filter 3, regular coffee H is extracted, and the hot water containing an extraction component oozes out from the filter 3 and is stored in the cup C.
[0030]
As described above, since the reinforcing portion 57 is formed in an accurate line-symmetric shape with the side bent portion 17 as the center, even if hot water is poured into the opening 37 of the filter 3, it follows the filter 3 of the pair of holder halves 19. It is possible to reliably restrict the portions from approaching each other and prevent the opening 37 from being inadvertently closed.
[0031]
This drip bag 51 can be manufactured by so-called bag-filling in the same manner as the drip bag 1 according to the first embodiment.
