Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drip bag, and in particular, to a so-called cup-on type drip bag in which a cardboard holder is attached to a filter bag filled with an extraction raw material and the holder is raised and placed on a cup when used. is there.
[0002]
[Prior art]
To put the filter bag on a cup in one of the forms, such as regular coffee, in which the extraction raw material of a type that pours hot water to extract ingredients is enclosed in a filter bag in a single amount. There is a drip bag with a holder.
There are various specific forms of this holder, but basically, the part pasted on the filter bag and the part to be put on and engaged with the mouth of the cup are integrally formed of cardboard, and these This part is provided in a flat folded form together with the filter bag, and is configured to raise each part of the holder in three dimensions when in use.
[0003]
An example a of such a drip bag is shown in FIG. The figure (A) shows the drip bag a in the form folded up flat, and the figure (B) shows in the use condition put on the cup.
b represents a filter bag, and c represents a holder. The filter bag b is formed so as to form an inverted trapezoidal flat bag with a liquid-permeable bag material sheet, and its upper end is a mouth that can be easily opened with an easily peelable adhesive, etc. Is filled with an appropriate amount of regular coffee.
[0004]
The holder c has two side walls d that are horizontally long and generally upside-down trapezoidal, and the ends of the side walls d are continuous, and can be opened in a cylindrical shape as shown in FIG. It has become. Portions other than the left and right end portions of the two side walls d sandwich the filter bag b, and the upper end portions of the filter bag b and the side wall d are bonded to each other. The two side walls d are formed with substantially inverted “h” -shaped insertion pieces e by horizontally cutting out two upper and lower portions in the region overlapping the filter bag b, and the insertion pieces e are formed at the left and right ends of the insertion pieces e. A broken line f is provided to make the insertion piece e easier to bend inward than the remaining portion.
[0005]
This drip bag a is used as follows. First, while holding the center of the upper end of the two side walls d of the holder c and pulling them opposite to each other to open the mouth of the filter bag b, the holder c is expanded into a cylindrical shape, and the insertion piece e is bent inward. Is put into the target cup h, and almost the lower half of the filter bag b fits in the cup h, and the lower end g of the side wall d closely contacts the upper end of the peripheral wall of the cup h from the outside. To do. The height position with respect to the cup h is determined by the left and right ends of the insertion piece e getting on the mouth of the cup h.
Here, hot water is poured into the filter bag b to extract coffee components.
[0006]
[Problems to be solved by the invention]
According to this drip bag a, since the opening of the cup h is almost pinched between the inner and outer sides at two places, the holder c can be firmly attached to the cup h, and the upper end of the holder c is the caliber of the cup h. However, there is an advantage such as easy opening of the pouring port of the filter bag b and easy pouring of hot water. However, there are the following problems.
[0007]
First, since the holder c has a complete cylindrical shape, a general manufacturing method such as filling the bag material sheet while making the bag material sheet with the holder c attached to the bag material sheet is filled with coffee. It becomes practically impossible to manufacture by the bag filling method, and the work of filling the filter bag b with coffee is forced to be performed by the bag supply filling method.
As is well known, even if a high-speed filling machine is used for filling by the bag-feeding filling method, the processing capacity is currently limited to about 30 to 40 pieces per minute, and bag making is performed while making bags. Compared to the filling method, the processing speed is extremely slow.
In addition, the bag feeding and filling machine is extremely expensive because of its complicated structure, and this price increases the manufacturing unit price per drip bag.
[0008]
Moreover, since the diameter of the coffee cup is generally about 7 to 8 cm, the width of the filter bag b is usually formed to a size that can be accommodated in a cup of this size with some margin, and the size of the holder is also this level. However, in the conventional drip bag a, the width of the holder c is about 1.5 times the width of the filter bag b. The size of the holder c becomes considerably large for the size of b. Therefore, not only the paper material used for the holder c but also a large amount of materials for outer packaging are consumed, so that the manufacturing cost is high, and the bulk is large, and there is a problem that it takes a place for transportation and storage.
[0009]
Furthermore, in the cup-on type drip bag, depending on the type and form of the extraction raw material to be filled, the height position of the filter bag b in a state of being placed on the cup is selectively set. In some cases, the filter bag b is a dipping type in which the filter bag b sinks deeply in the cup h, and in other cases, a drip-on type in which the original drip that does not occur is performed. When the immersion type is used, the position where the holder c is attached to the filter bag b is set higher, and the bottom of the filter bag b is sufficiently lower than the cup mounting line of the holder c. The attachment position of the holder c with respect to the bag b is set to be low so that the bottom of the filter bag b does not become much lower than the cup mounting line of the holder c.
[0010]
In this respect, since many of the drip bags that are forced to be manufactured by the bag supply and filling method like the conventional drip bag a have a fixed positional relationship between the holder c and the filter bag b, one holder Will be dedicated to one type. This cannot reduce the mass production cost.
[0011]
The present invention has been made in view of the above-described conventional problems, and the inner side of the cup can be held inside the cup while holding the filter bag even with a holder that is almost the same as or smaller than the size of the filter bag. The part that fits in the cup and the part that gets on the mouth of the cup can be made, the state put on the cup can be kept stable, the force to open the mouth of the filter bag can be given, and the bag making An object of the present invention is to provide an epoch-making drip bag that can be filled and that can selectively set the attachment position of the holder to the filter bag, and a method for manufacturing the drip bag.
[0012]
[Means for Solving the Problems]
In order to achieve this object, the drip bag according to claim 1 is folded in two in a state before the folding, and the filter bag filled with the extraction raw material and provided with the tear-off line along the upper edge. And a paper holder sandwiching the filter bag in a state in which the two fold lines overlap another side edge of the side edge of the filter bag extending in a direction orthogonal to the upper edge, The arm that is at least the lower part of the region that is biased toward the fold line side and that is continuous with the remaining part only at the end of the fold line side, and across both sides of the fold line. A fold portion surrounded by an extended cut line and a fold line extending downward from both ends of the cut line is provided, and is attached to the filter bag in a region other than the arm. It is.
[0013]
In this drip bag, when the folding part is folded inside the two holder halves, this folding part works as a tension member, and the two holder halves, ie, the parts on both sides of the folding line, are opposite to each other. It is curved to the side, and the opening force is urged to the filter bag along with this curve, and the two arms open in a V shape. The overhanging part that protrudes in a substantially bowl shape remains with respect to this part. Here, when the upper edge of the filter bag is cut off from the cut line and the mouth is opened, the mouth is pulled wide by the curved holder half. This is the shape at the time of use.
[0014]
In this form at the time of use, a total of three locations of the overhang portion and the two arms are positioned so as to surround the filter bag from the outside, and if these three locations are attached to the opening edge of the desired cup, the drip bag is stabilized. Can be placed on the cup in a posture. In addition, the part of the holder below the cup mounting line that connects the arm and the lower edge of the overhanging part fits in the cup with the filter bag in hand, so this part moves laterally on the cup. To prevent.
Therefore, according to this drip bag, a holder that is not cylindrical and is only folded in half with a size that is approximately the same as or smaller than the size of the filter bag can be fitted inside the cup while holding the filter bag. Three places on the cup mouth can be made, the state of being placed on the cup can be kept stable, and the mouth of the filter bag can be opened firmly.
[0015]
The position where the holder is bonded to the filter bag is not particularly limited, but it is desirable to include both the left and right ends of the holder excluding the arm at this position. It will be in the form of holding a filter bag.
There are no particular restrictions on the specific shape of the arm or the folded portion, but it is desirable that these lower edges are basically positioned on a straight line.
[0016]
The drip bag according to claim 2 is the drip bag according to claim 1, wherein the filter bag has a shape in which three side edges other than the folded edge of the folded rectangular bag material sheet are sealed. The holder is characterized in that the filter bag is sandwiched with the two fold lines overlapping the folded edge of the filter bag.
[0017]
In this case, the folding direction of the bag material sheet and the folding direction of the holder coincide with each other, so that the holder before being folded can be attached to the bag material sheet and folded together. The bag material sheet thus folded is first sealed on both side edges of the bag material sheet, and the bag material sheet is formed into a sleeve shape, and then the extraction raw material is filled in a state where the mouth of the sleeve shape is sealed. Bag-filling is possible.
[0018]
The manufacturing method according to the sixth aspect of the present invention embodies the manufacturing method of the drip bag with filling by the bag making and filling method.
That is, the manufacturing method of the drip bag according to claim 6 is provided in a region where a long bag material sheet having liquid permeability and a fold line for folding in two are provided and biased toward the anti-fold line side. An arm that is continuous with the remaining portion only at the end of the fold line side, a cut line formed so as to extend on both sides of the fold line, and a fold line extending downward from both ends of the cut line Using a paper holder with an enclosed folding part, the folding line is the width direction of the bag material sheet for the traveling bag material sheet with the adhesive applied to the area other than the arm Affixed at regular intervals so as to overlap with the intermediate line, the bag material sheet is folded in the width direction with the holder, and both side edges of the two folded bag material sheets are sealed to seal the bag material sheet Go into shape, this shape The bag material sheet is sequentially subjected to final sealing between adjacent holders, and the extraction raw material is filled in the inside of the front end of the seal of the bag material sheet before the next final sealing is performed. .
[0019]
The drip bag described in claim 3 is the drip bag described in claim 2, characterized in that the vertical width of the holder is approximately half or less than the vertical width of the filter bag.
In the present invention, since the tear line that is the opening means of the filter bag is independent of the holder, the size of the holder with respect to the filter bag is set as in claim 3 while using the same holder. By simply changing the position where this is attached to the filter bag in the vertical direction, an immersion drip bag in which the filter bag is immersed in the extract accumulated in the cup and an original drip type in which the filter bag is not immersed in the extract Both drip bags can be made selectively.
[0020]
That is, if the holder is affixed to the bottom of the filter bag, the distance from the arm or overhang to the bottom of the filter bag is shortened to the original drip type, and conversely, the holder is affixed to the filter bag near the cut line. If attached, the distance from the arm or overhanging part to the bottom of the filter bag becomes longer, resulting in an immersion type.
In order to change the attachment position of the holder with respect to the filter bag, the supply phase of the holder with respect to the bag material sheet may be changed, or the position of the final seal may be changed.
[0021]
The drip bag according to claim 4 is the drip bag according to any one of claims 1 to 3, wherein the holder is provided with a catching claw protruding downward from the free end of the arm, and 2 of the broken lines. The intermediate portion including the fold line is displaced downward from both sides thereof.
Therefore, when the folding part is folded inside the holder half, the part surrounded by the middle part of the cut line remains in a nail-like shape protruding downward from the corner of the overhanging part, so that the drip bag is placed on the cup Then, the claw-like portion and the hook claw of the arm face the cup from the outside to prevent the drip bag from falling off.
[0022]
The drip bag according to claim 5 is the drip bag according to any one of claims 1 to 4, wherein the drip bag is continuous with the remaining portion only at the end opposite to the fold line in the region lower than the arm of the holder. And a locking means for locking with the mating connecting piece is provided at a position near the free end of the connecting piece.
[0023]
When the connecting pieces are raised so as to oppose each other and the respective locking means are locked to each other, the free ends of the two connecting pieces are connected to each other. Are connected to form a completely enclosing loop shape, which further stabilizes the holding of the filter bag by the holder. And since the forces in the direction of opening each other are generated at the base of the connecting pieces where the free ends are connected to each other, the holders are rounded as a whole, The pouring spout of the filter bag will open further.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
Below, the drip bag which concerns on embodiment of this invention is demonstrated according to drawing. In each of the embodiments shown in the drawings, the present invention is applied to a coffee drip bag.
[0025]
[1. First Embodiment] (FIGS. 1 to 5)
1 to 5 show a drip bag 1 according to a first embodiment and a manufacturing method thereof.
The drip bag 1 includes a filter bag 3 filled with regular coffee and a holder 5 that holds the filter bag 3, and is provided in a sealed form with an outer bag (not shown) having gas barrier properties.
The holder 5 is folded in half before it is folded, and the holder 5 in this shape sandwiches the filter bag 3 in the thickness direction. Is bonded to the filter bag 3.
[0026]
[A. Structure] (Fig. 1)
[A-1. Filter bag)
The filter bag 3 is formed in a rectangular flat bag shape that is long in the left-right direction (the direction toward the lower left in FIG. 1 is the left side and the direction toward the upper side is the upper side), and the right side edge is the folded edge 3a. The remaining three side edges of the folded bag material sheet are sealed. As the bag material sheet, a flexible and liquid-permeable material that can be heat-sealed such as heat sealing or ultrasonic sealing, for example, a nylon nonwoven fabric having a basis weight of about 30 g / square m is used. The filter bag 3 is provided with a perforated cut line 3d extending parallel to the seal side edge 3b at a position close to the upper seal side edge 3b. This cut line 3d is for opening, and a pouring opening is opened in the filter bag 3 by cutting the upper side from here.
The filter bag 3 is filled with coffee by a bag making filling method. This will be described later.
[0027]
[A-2. holder〕
The outer shape of the holder 5 is a shape in which two holder halves 7 each having a horizontally long rectangular shape are formed by folding a thick cardboard that is long in the left-right direction into two at a half-fold line 6 engraved in the middle in the longitudinal direction. The portions of the two holder halves 7 are symmetrical with respect to each other with respect to the folding line 6. FIG. 1 (B) shows the holder 5 flatly developed and shown from the back side. As for the size of the holder half 7, its left and right length is slightly shorter than the left and right length of the filter bag 3, and its vertical width is slightly shorter than half of the vertical width of the filter bag 3.
In the following description, the concept of mountain folding is a concept in which folding in a direction in which a ridge line is formed on the surface facing outward in a state where the holder 5 is folded in two by a folding line 6 is mountain folding.
[0028]
The holder half 7 is provided with a cut line 8 in which approximately half of the half far from the fold line 6 is vertically divided into two, and an upper part of the cut line 8 is an arm 9. Therefore, the arm 9 is continuous with the remaining portion only at the end on the side of the double fold line 6.
Most of the cut line 8 extends straight in the left-right direction, but only the tip part on the side opposite to the fold line 6 is bent in an L shape downward to reach the tip edge. As a result, a catching claw 9a is formed on the tip (free end) of the arm 9 so as to protrude downward in a substantially bowl shape.
[0029]
In addition, the holder 5 is provided with a cut line 10 extending over both sides of a substantially intermediate position of the double fold line 6. The cut line 10 has a total length of about one-sixth of the left and right length of the holder 5, and its intermediate portion 10a is displaced to some extent below both sides and bent into a U-shape. Other than this intermediate portion 10a The portion extends at the same height as the cut line 8. A broken line 11 extending downward from both ends of the broken line 10 is provided. A region surrounded by the broken line 10 and the mountain fold line 11 is a fold portion 13, and a portion above the fold portion 13 becomes an overhang portion 15. The protruding portion 15 includes a protruding portion surrounded by an intermediate portion 10a of the cut line 10, and this protruding portion becomes a catching claw 15a.
A portion of the cut lines 8 and 10 that extends straight in the left-right direction is a cup mounting line L.
[0030]
The holder 5 formed in this way has two fold lines 6 that overlap the folded edge 3a of the filter bag 3 so that the two holder halves 7 sandwich the filter bag 3 in the thickness direction, and in regions other than the arm 9 It is adhered to the filter bag 3 by an adhesive 17 applied to the back surface. The positions where the adhesive 17 is applied are the front end portion on the side opposite to the fold line 6 in the region below the cup mounting line L and the back surfaces of the overhang portions 15.
The position where the holder 5 is affixed to the filter bag 3 is specified as a position where the double fold line 6 overlaps the folding edge 3a in the left-right direction, but selectively within a range not overlapping the cut line 3d of the filter bag 3 in the vertical direction. Is set. In the drawing, an example is shown in which the holder 5 is attached at a high position that is biased toward the cutoff line 3d.
[0031]
Since the holder 5 is configured as described above, the arm 9 can be folded sideways with respect to the remaining portion, and the folding portion 13 can be folded inside the two holder halves 7.
The drip bag 1 is configured as described above.
[0032]
[B. Manufacturing method] (FIGS. 2 and 3)
Next, a method for manufacturing the drip bag 1 will be described with reference to FIGS.
Reference numeral 21 denotes a bag material sheet which is a material of the filter bag 3. The bag material sheet 21 is in the form of a long tape having a width that is twice the width required for the filter bag 3, and is continuously drawn out from a supply reel (not shown).
[0033]
The holder 5 is printed on the surface thereof in a desired manner, and after being punched into a predetermined shape with the above-described double fold lines 6, cut lines 8, 10 and mountain fold lines 11, an adhesive 17 is applied. In this state, the adhesive 17 is attached to the traveling bag material sheet 21 at regular intervals. FIG. 2 shows this state. That is, the holder 5 is not folded in two so that its left-right direction coincides with the width direction of the bag material sheet 21 and the two fold line 6 overlaps the virtual intermediate line 21 a in the width direction of the bag material sheet 21. And is attached to the bag material sheet 21.
[0034]
Then, the bag material sheet 21 is passed through a sleeve forming mechanism (not shown) at the tip of the position where the holder 5 is attached, and together with the holder 5 as shown in FIG. 3 by the guide member of the sleeve forming mechanism. The two side edges in the width direction are overlapped by being folded in the width direction, and the both side edges thus overlapped are heat-sealed by the heating roller 23. This two-folding is performed at the virtual intermediate line 21 a, and this virtual intermediate line 21 a becomes the folded edge 3 a of the filter bag 3. And the seal | sticker by the heating roller 23 forms the horizontal seal side edge 3c (refer FIG. 1 etc.) of the filter bag 3. FIG. This sealing may be a method other than heat sealing such as ultrasonic sealing.
[0035]
In this way, the bag material sheet 21 is processed into a sleeve shape, and a final seal 25 having a certain width is formed and sealed by a seal and cut mechanism (not shown) at a position ahead of the sleeve forming mechanism. It is cut at an intermediate position in the width direction in the area.
In the region where the final seal 25 is made, the lower half from the cut line becomes the upper seal side edge 3b and the upper half becomes the lower seal side edge 3b '. That is, this seal and cut is sequentially performed on the position between the two adjacent holders 5 and 5, and this seal and cut is performed between the subsequent holders 5, so that the filter is closed on all sides. One bag 3 is completed and cut off from the subsequent portion, and the lower seal side edge 3b 'remains at the tip of the subsequent portion.
When trying to obtain the drip bag 1 in a continuous form, the final seal 25 may be performed by a method that does not involve cutting.
[0036]
A perforation cutter located on the side of the bag material 21 on the front side in the traveling direction is integrally attached to the processing head for performing the sealing and cutting, and the cut line 3c of the filter bag 3 is formed by the perforation cutter. Provided.
[0037]
Reference numeral 27 denotes a filling nozzle extending from a coffee hopper (not shown). The filling nozzle 27 is inserted into the inside of the bag material sheet 21 which is formed into a sleeve shape from a position before the sleeve forming mechanism, and after the sealing and cutting of the bag material sheet 21 is performed, the bag material A predetermined amount of coffee is dropped from the filling nozzle 27 into the inside of the seal tip side of the sheet 21, and then the next seal and cut is executed. In this way, coffee is filled during bag making.
Thus, the filter bag 3 filled with a certain amount of coffee is manufactured, and at the same time, the drip bag 1 in the form in which the holder 5 folded in half with the filter bag 3 is bonded with the adhesive 17 is completed.
[0038]
[C. How to use] (FIGS. 4 and 5)
Next, how to use the drip bag 1 will be described.
First, the folding part 13 of the holder 5 is pushed with a fingertip or the like, and the folding part 13 is folded inside the two holder halves 7 and 7 as shown in FIG. For example, this operation is performed by inserting a fingertip between the side of the folding portion 13 and the filter bag 3 to appropriately open the folding portion 13 in a V-shape, and from that state, use another finger to connect the middle portion (2 The position where the fold line 6 passes is pushed in and the direction of the V-shape is reversed left and right. The folded portion 13 folded in this way maintains a V-shaped open shape due to the rigidity of the holder 5 itself, unless a force that folds the folded portion 13 is intentionally applied. Therefore, the folded portion 13 of this shape works as a tension member, and urges the opening force in the direction away from each other to the two holder halves 7 so that the two holder halves 7 warp to the opposite sides. Slightly curved. Further, since the folding portion 13 is folded in this way, the overhanging portion 15 remains in a shape protruding in a hook shape to the right side with respect to the remaining portion.
[0039]
Here, the end on the side of the upper seal side edge 3b of the filter bag 3 is cut off by a cutting line 3d as shown by a two-dot chain line in FIG. Then, the holder halves 7 that have been substantially folded with respect to each other with the filter bag 3 interposed therebetween are greatly expanded to the opposite sides as shown in FIG. 5 due to the opening force urged by the folding portion 13. While curving, the pouring gate 29 of the filter bag 3 is opened widely. At this time, since the arms 9 are not directly bonded to the filter bag 3, the arms 9 open in a V shape as the holder half 7 curves.
[0040]
When taking the coffee extract, as shown in FIG. 5, the holder 5 opened in a V shape is placed on the opening edge of an appropriate cup 30. That is, while putting the lower part of the filter bag 3 in the cup 30, the two arms 9 and the overhanging portion 15 are put on the opening edge of the cup 30. As a result, the filter bag 3 is suspended from the holder 5 so as to face the cup 30 from above, and the portion of the holder 5 below the cup mounting line L is held in the cup 30 while holding the filter bag 3. Fits in. The position at which the arm 9 and the overhanging portion 15 ride on the cup varies slightly depending on the size of the cup 30, but in any case, a total of three places of the arm 9 and the overhanging portion 15 ride on the cup 30, so the holder 5 on the cup 30 The posture is very stable. And the part below the cup mounting line L of the holder 5 fits in the cup 30, and the catching claw 9 a of the arm 9 and the catching claw 15 a of the overhanging portion 15 face the edge of the cup 30 from the outside. Alternatively, by engaging, the lateral movement and dropout of the drip bag 1 are almost certainly prevented.
[0041]
As can be seen from FIG. 5, in the state where the drip bag 1 is placed on the cup 30, the filter bag 3 as well as the holder 5 has almost no portion protruding sideways from the cup 30.
[0042]
In addition, when it is desired to open the pouring gate 29 larger, or when it is desired to increase the V-shaped opening angle of the two arms 9, it is intentionally bent so that a crease is attached around the middle of the holder half 7 in the horizontal direction. The lower part of the holder 5 from the cup mounting line L may be made close to a circle.
Further, when using a smaller cup, if the portions on the free end side in the portion below the cup mounting line L are overlapped, this portion is considerably narrowed, so that it is also used for a cup having an inner diameter of about 5 cm. be able to.
[0043]
[D. (Change holder attachment position and type)
In the drip bag 1 shown in the drawing, since the position where the holder 5 is attached to the filter bag 3 is set to a high position, that is, a position closer to the cut line 3d, the filter bag 3 is removed from the cup mounting line L of the holder 5. The distance to the lower end becomes longer, and in many cases, the bottom of the filter bag 3 is immersed in the extract that accumulates in the cup when drip. Accordingly, the drip bag 1 shown in the drawing is of a type suitable for extraction by the dipping method.
[0044]
In order to make this a drip-on type in which the drip-on type in which the filter bag 3 is not immersed in the extract accumulated in the cup, the position where the holder 5 is attached to the filter bag 3 may be lowered. For example, the bonding position of the holder 5 may be changed so that the cup placement line L comes to the vicinity indicated by the two-dot chain line in FIG.
