Description

The present invention relates to a dripper, for example, a dripper used for straining contents having components to be extracted (e.g., regular coffee powder, black tea leaves, green tea leaves, etc.) and contents having components to be extracted. relates to a pre-stored dripper.

Disposable type coffee drippers are conventionally known which consist of a bag-like filter for containing regular coffee grounds and a cylindrical support (sleeve-like mount) for positioning the filter on a cup. The support is often made of cardboard, and before use the support is folded with the filter attached to the inside. When brewing coffee, after opening the support from the folded state to the cylindrical state, the dripper is placed on the cup and regular coffee powder is put into the filter. In the case of the type in which regular coffee grounds are enclosed in the filter in advance, the filter is unsealed, the support body is changed from the folded state to the cylindrical open state, and then the dripper is placed on the cup. In either case, pouring hot water into the filter causes the extracted coffee to pass through the filter and accumulate in the cup.

The coffee dripper as described above is a disposable type that is easy to dispose of, yet is convenient because drip coffee can be brewed easily. However, in order to pour hot water into the filter, the support must be held in a tubular open position. Various types of drippers have been proposed in the past. For example, the drippers described in Patent Documents 1 and 2 have a lock structure provided on both sides, and have a configuration in which the shape of the support is fixed in a cylindrical open state. It's becoming

JP 2010-99462 A JP-A-2004-711

In the drippers described in Patent Documents 1 and 2, the dripper is not fixed to the cup with a locking structure. It's becoming The width of the filter is also substantially the same as the width of the support. In other words, both the support and the filter are in the shape of a nearly rectangular bag, and the side surfaces of the filter are steeply slanted. For this reason, it is not possible to steam the coffee grounds on the filter side or slowly flow the coffee along the filter side.

If the shape of the support and the filter is close to a large sector on the opening side, the gentle slope of the filter side surface and the contact of the filter side surface with the support will effectively steam the ground coffee and control the flow rate of the coffee. It becomes possible to do so, and it becomes possible to increase the capacity. Furthermore, it becomes easier to pour hot water into the filter, and the splashing of coffee to the outside of the filter is less likely to occur. However, the closer the shape of the filter is to a sector, the higher the center of gravity of the dripper due to the coffee grounds that have become heavy after absorbing hot water, making the dripper less stable on the cup. Also, the dripper will not be stable if it does not match the cup size.

The present invention has been made in view of this situation, and its object is to be able to handle various cup sizes and to maintain high stability on the cup even if the filter opening is large. It is to provide a dripper that can

In order to achieve the above object, the dripper of the first invention comprises a bag-like filter, a cylindrical support that is foldable with the filter positioned inside, and the cylindrical support. and a flat plate-shaped pedestal formed so as to be attachable so as to be locked.

1 and 2 show drippers 10A and 10B according to first and second embodiments, respectively. FIG. 1 shows the appearance of the dripper 10A set on the cup 11 in the state of use after opening, (A) is a top view of the dripper 10A, (B) is a front view of the dripper 10A, (C) is a side view of the dripper 10A. FIG. 2 shows the appearance of the dripper 10B set on the cup 11 in the state of use after opening, (A) is a top view of the dripper 10B, (B) is a front view of the dripper 10B, (C) is a side view of the dripper 10B.

FIG. 3 shows the filter 1 and support 2 that constitute the drippers 10A and 10B. In FIG. 3, (A) is a front view of the filter 1 and the support 2 before unsealing (the support 2 is folded), and (B) is a state after the filter 1 and the support 2 are unsealed (the support 2 is a front view of the cylindrical open state).

The drippers 10A and 10B are composed of a bag-shaped filter 1, a tubular support (sleeve-shaped mount) 2 formed so as to be foldable with the filter 1 positioned inside, and a tubular support 2. It is configured to have flat-plate-like pedestals 3A and 3B that can be attached so as to be locked. These drippers 10A and 10B are suitable for carrying because the support 2 is foldable and the pedestals 3A and 3B are flat plate-shaped, and have a simple structure that can be made of materials (such as paper) that are easy to dispose of. Therefore, it is suitable for disposable use. In other words, it has the advantage that it is a portable, disposable type, but can easily brew drip coffee, for example.

Contents 12 ((A) of FIGS. 1 and 2; for example, regular coffee powder, black tea leaves, green tea leaves, etc.) having components to be extracted are put into the filter 1 at the time of use, or pre-packaged inside. When the content 12 is sealed in the filter 1 in advance, the opening 9a of the filter 1 is sealed by ultrasonic sealing via the support 2 so that the content 12 does not spill out of the filter 1 before the drippers 10A and 10B are used. is peelably closed.

As for the material of the filter 1, in consideration of workability when forming into a bag shape, a sheet material having heat adhesiveness as a raw material, a sheet material having heat adhesiveness on one side (the innermost layer when made into a bag shape), etc. is preferably used. For example, water-permeable non-woven fabric made of polyolefin (polyethylene, polypropylene, etc.) or polyester material, polyolefin (polyethylene, polypropylene, etc.), polyester thermoplastic resin on one side (innermost layer when bag-shaped) A multi-layered filter paper containing in. The bag-like processing of the filter 1 is performed, for example, by folding the above-mentioned sheet material in two or gusset-folding them, overlapping them, thermally adhering them into a predetermined shape, cutting and die-cutting. If the bottom of the filter 1 is gusset-folded, the capacity of the drippers 10A and 10B can be effectively increased.

FIG. 4 shows sheet material 1A of filter 1 used for drippers 10A and 10B. First, the sheet material 1A is folded along the folding line N1 and overlapped, and the left and right sides are heat-bonded to form a bag. When the contents 12 ((A) of FIGS. 1 and 2) are enclosed in advance in the filter 1, after the contents 12 are put into the filter 1, ultrasonic waves are applied through the support 2 as described above. A seal releasably closes the filter opening 9a. Next, when the upper end of the filter is folded along the folding line N2 and adhered to the support 2, the pre-opening state shown in FIG. 3(A) is obtained.

It is the tubular support 2 that enables the filter 1 to be set on the cup 11 (FIGS. 1 and 2) in combination with the pedestals 3A and 3B while maintaining a predetermined shape. As shown in FIGS. 1 to 3, the support 2 has a first opening 7 forming one opening 7a, a second opening 8 forming the other opening 8a, and an inward pressing (see FIG. 3). 3(A) with fold lines M1 and M2 formed by arrows mP) and locking structures 13 that fix the support shape in a tubular open state.

The support 2 is formed by bending and adhering one blank plate 2A shown in FIG. FIG. 5 is a developed view of the support 2, and the blank plate 2A is formed by punching a plate-shaped sheet material as shown in FIG. The material of the blank plate 2A is not particularly limited, but the support 2 is preferably made of paper. For example, thick paper such as waterproof card paper and ivory paper, and thick paper coated with a resin (polyethylene or the like) on both sides (especially the inner surface of the support 2) are preferably used as the sheet material. If the blank plate 2A is made of thick paper coated with resin, even if the support body 2 is exposed to hot water or steam, the rigidity of the support body 2 can be prevented from being lowered.

The blank plate 2A (FIG. 5) is composed of three parts bounded by a linear bending line L1, that is, a front plate 4, a rear plate 5 and a margin piece 6. As shown in FIG. The front plate 4 and the rear plate 5 are provided with a slit-shaped locking hole 2a, a crescent-shaped hole 2b, a curved bending line L2, and the like, symmetrically. Specific examples of the folding lines L1 and L2 include creases such as press creases, cut creases, perforated creases, and lead creases. , L2. That is, a notch partially provided with a press crease is assumed as the bending line L1, and a notch partially provided with a connecting portion (blade stopping portion) is assumed as the bending line L2.

When assembling the support 2, first, the blank plate 2A is bent along the bending line L1 of the boundary between the front plate 4 and the rear plate 5 so that the front plate 4 and the rear plate 5 are overlapped. Next, the blank plate 2A is folded along the bending line L1 at the boundary between the front plate 4 and the paste strip 6 so that the paste strip 6 overlaps the back plate 5. - 特許庁In this state, when the paste margin piece 6 is adhered to the back plate 5, the blank plate 2A becomes cylindrical and the support 2 in the folded state is obtained. Furthermore, when the filter 1 is attached in the support 2, the filter 1 and the support 2 in the folded state (FIG. 3(A)) are obtained as described above.

By folding the blank plate 2A along each folding line L1, a linear folding line M1 (FIGS. 1 to 3) is formed at each folding line L1. When the left and right folding lines M1 are pressed toward each other (in the direction of arrow mP) with respect to the folded support 2 (FIG. 3A), force is concentrated on the curved folding line L2. Therefore, the blank plate 2A can be easily folded along the folding line L2. By this bending, curved fold lines M2 are formed at the positions of the respective fold lines L2 (FIG. 3B), and openings 7a and 8a (FIG. 1 and (C) of FIG. 2) are formed. Then, the support 2 is opened in a cylindrical shape, and an opening 9a ((A) in FIGS. 1 and 2) is formed in the filter opening 9 as well. The creases M1 and M2 formed as described above function as a lock structure 13 that fixes the shape of the support 2 in the tubular open state.

The lock structure 13 consists of the fold line M1 formed by folding the support 2 and deformed by pushing it inward, and the fold line M2 formed by pushing against the fold line M1, as described above. The folding line M1 is formed linearly from the first opening 7 to the second opening 8 on both sides of the support 2 in the folded state (FIG. 3A). The support body 2 in the folded state is formed with bilaterally symmetrical curved folding lines L2, and folding along the folding lines L2 forms a curved folding line M2 (FIG. 3B). ). By pressing the support 2 from the left and right (arrow mP in FIG. 3A), the folding line M2 is formed in a curved mountain fold toward the outside of the support 2, and the shape of the support 2 becomes cylindrical. It is fixed in the open state. At this time, the folding line M1 is deformed into a curved shape, thereby strengthening the shape fixation of the support 2 and the feeling of locking.

The first opening 7 has a filter opening 9 (see FIG. 1) so that the filter 1 opens when the support 2 is changed from the folded state (FIG. 3(A)) to the cylindrical open state (FIG. 3(B)). , (A) of FIG. 2) are attached. The filter 1 is attached by bending the upper end of the filter along the bending line N2 (FIG. 4) and adhering it to the support 2, as described above. That is, the filter 1 is inserted into the support 2, a part of the filter opening 9 is folded outward at the edge of the first opening 7 of the support 2, and the folded part is attached to the outer surface of the support 2. (two points at the upper end of the support 2). When the filter 1 is attached in this way, when the support 2 is in a cylindrical open state (FIG. 3B, etc.) during use, the filter 1 opens wide and becomes a state suitable for pouring or dripping.

The drippers 10A and 10B are completed by setting the support 2 assembled as described above on the pedestals 3A and 3B as shown in FIGS. The plan view of FIG. 6 shows the pedestal 3A constituting the dripper 10A, and the plan view of FIG. 7 shows the pedestal 3B constituting the dripper 10B. The pedestals 3A and 3B are formed with holes 3a that allow the support 2 to be inserted from the second opening 8 side, and locking claws 3c are formed at the edges of the holes 3a. However, since the pedestal 3B before use is formed with a flap 3d that can be opened and closed that constitutes the hole 3a, the hole 3a before the support 2 is inserted is closed by the two flaps 3d. there is The ends of the two flaps 3d closing the hole 3a are connected by a cutoff line C1, and when the two flaps 3d are cut off along the cutoff line C1, a folding line L3 (FIG. 7) consisting of a press crease is formed. It becomes rotatable around the center (can be folded into double doors).

When the support 2 is inserted into the hole 3a, the locking claw 3c is caught in the locking hole 2a formed in the side surface of the support 2, and the support 2 is locked to the pedestals 3A and 3B. (Figures 1 and 2). This locked state stabilizes the fixing between the support 2 and the pedestals 3A and 3B. When the locking pawl 3c is caught in the locking hole 2a, a click feeling is obtained, so that the completion of fixing can be reliably known (strengthening of locking feeling). The height of the filter 1 relative to the cup 11 can be determined by adjusting the positions of the locking holes 2a in the support 2. FIG. For example, by setting the position of the locking hole 2a so that the lower end of the filter 1 is positioned above the cup 11, the filter 1 can be prevented from soaking in the coffee in the cup 11 (securing the brewing time). etc).

Since the support 2 and the pedestals 3A and 3B are separate parts, it is possible to obtain a form similar to that of a commercially available drip appliance, and the lock structure 13 can stably hold the form. That is, it is possible to produce the same flow of coffee as in the case of using a commercially available drip device, and to effectively steam the coffee grounds, control the flow rate of the coffee, and the like. Furthermore, since the pedestals 3A and 3B are flat plate-shaped, the degree of freedom to accommodate various cup sizes is obtained, and stable placement on the cup 11 is possible.

The crescent-shaped hole 2b formed in the support 2 acts so that the locking claw 3c can be easily caught in the locking hole 2a. That is, when the support body 2 is engaged with the pedestals 3A and 3B by the engaging claw 3c being caught in the engaging hole 2a, a flat surface is formed between the engaging hole 2a and the hole 2b. As a result, the locking claw 3c is easily caught in the locking hole 2a. The hole 2b can also be used to check the liquid level in the filter 1.

The flap 3d provided on the pedestal 3B (FIG. 7) is rotatable about the folding line L3, so that the flap 3d is pushed by the second opening 8 of the support 2 and rotates ( Arrow mR in FIG. 2(C)). When the locking claw 3c is caught in the locking hole 2a and the supporting body 2 is attached to the pedestal 3B in a locked state, the angle of the flap 3d with respect to the hole 3a becomes 90° or more (Fig. 2(C)). The strength of the pedestal 3B is improved by having the flap 3d, and even if the dripper 10B moves on the cup 11, the flap 3d comes into contact with the inner surface of the cup 11 to restrict its movement. 11 can be effectively prevented from falling off the top. Therefore, the dripper 10B can maintain high stability on the cup.

When using the drippers 10A and 10B, for example, when brewing coffee, the support 2 is pushed from the left and right sides (arrow mP in FIG. 3A) to fold the support 2 (see FIG. 3 ( After opening the filter 1 from A)) to the tubular open state (FIG. 3(B)), it is set on the pedestals 3A and 3B to complete the drippers 10A and 10B. Drippers 10A and 10B are placed on cup 11, and regular coffee grounds are introduced into filter 1 as content 12 ((A) in FIGS. 1 and 2). In the case of the type in which regular coffee grounds are enclosed in the filter 1 in advance, the filter 1 is opened, the support 2 is changed from the folded state to the cylindrical open state, and then set on the pedestals 3A and 3B to form the dripper 10A. , 10B are completed, and the drippers 10A, 10B are placed on the cup 11 . In either case, when hot water is poured into the filter 1 through the opening 9a, the extracted coffee passes through the filter 1 and accumulates in the cup 11.例文帳に追加

By pouring a predetermined amount of hot water into the filter 1 through the opening 9a as described above, the beverage (coffee, black tea, green tea, etc.) in which the desired components are extracted from the content 12 in the filter 1 is poured into the cup 11. can get to The opening 7a formed by the first opening 7 is larger than the opening 8a formed by the second opening 8, and the filter 1 has a sector shape. In other words, the support 2 and the filter 1 are shaped like a fan that is larger toward the openings 7a and 9a. Therefore, due to the gentle inclination of the side surface of the filter 1 and the contact of the side surface of the filter 1 with the support 2, the same coffee flow as in a commercially available drip appliance is generated, and as described above, the coffee powder is steamed and the coffee flow rate is controlled. can be done effectively. In addition, it becomes possible to increase the capacity (increase the amount of coffee grounds, etc.), and the pouring of hot water into the filter 1 becomes easy. The fan-shaped instability can be eliminated by attaching the flat plate-shaped pedestals 3A and 3B to the support 2. FIG.

For example, when hot water is poured into the filter 1, even if coffee splashes, it is blocked by the pedestals 3A and 3B. In addition, when the drippers 10A and 10B are in use, the condition (liquid level, etc.) inside the cup 11 can be seen through the locking holes 2a and 3a, so the amount of coffee inside the cup 11 can be easily checked while pouring hot water. . The base 3B is provided with a window 3b (FIG. 7) around the flap 3d, so that the inside of the cup 11 (liquid level, etc.) can be seen through the window 3b located around the hole 3a during use of the dripper 10B. can see. Therefore, it is possible to more easily check the amount of coffee in the cup 11 while pouring hot water.

The plan views of FIGS. 8 and 9 show pedestals 3C and 3D before use that can be used for the drippers 10A and 10B. Like the base 3B, the bases 3C and 3D are formed with a flap 3d that can be opened and closed, forming a hole 3a, and an engaging claw 3c is formed at the edge of the hole 3a. However, instead of the window 3b (FIG. 7) located around the flap 3d, the window 3b forming a part of the hole 3a is constructed by expanding a part of the flap 3d. Since the state (liquid level, etc.) inside the cup 11 can be seen through the window 3b forming a part of the hole 3a, the amount of coffee inside the cup 11 can be easily confirmed while pouring hot water, similar to the dripper 10B. .

The pedestals 3A-3D may be made of paper or plastic. If both the support 2 and the pedestals 3A to 3D are made of paper, the drippers 10A and 10B can be discarded as they are after the extraction of coffee or the like is completed. Therefore, cleaning up is easy. If the support 2 is made of paper and the pedestals 3A-3D are made of plastic, the filter 1 and the support 2 can be discarded and the pedestals 3A-3D can be reused. Reuse of the pedestals 3A to 3D makes it possible to reduce the amount of dust.

As described above, according to the drippers 10A and 10B, the cylindrical support 2 can be attached to the flat plate-shaped pedestals 3A to 3D, so that various cup sizes can be accommodated. It is possible to maintain high stability on the cup 11 even if the opening of the filter 1 is large. Therefore, by making the shape of the support 2 and the filter 1 close to a fan shape that is large on the opening side, the gentle inclination of the side surface of the filter 1 and the contact of the side surface of the filter 1 with the support 2 allow the coffee grounds to steam and the coffee to flow. It becomes possible to effectively control the flow rate of the gas, and it is possible to increase the capacity. Furthermore, pouring hot water into the filter 1 is facilitated, and splashing of coffee to the outside of the filter 1 and outside of the drippers 10A and 10B is less likely to occur.
