Description

The present invention relates to a dripper, and for example, a dripper used when filtering 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. This relates to a pre-stored dripper.

Disposable coffee drippers have been known that are comprised of a bag-shaped filter that stores regular coffee powder, and a cylindrical support (sleeve-shaped mount) that positions the filter on a cup. The support is often made of cardboard, and before use the support is folded with a filter attached inside. When brewing coffee, the support is changed from a folded state to a cylindrical open state, a dripper is placed on the cup, and regular coffee powder is poured into the filter. For the type in which regular coffee powder is pre-filled in the filter, the filter is unsealed, the support is changed from a folded state to an open cylindrical state, and then a dripper is placed on the cup. In either case, pouring boiling water into the filter will cause the brewed coffee to pass through the filter and collect in the cup.

The coffee dripper described above is convenient because it is a disposable type that can be easily disposed of and can easily brew drip coffee. However, in order to pour hot water into the filter, it is necessary to hold the support in an open cylindrical state. Various types of drippers have been proposed in the past. For example, the dripper described in Patent Document 1 has a lock structure provided on both sides to fix the support shape in a cylindrical open state. There is.

Japanese Patent Application Publication No. 2010-99462

In the dripper described in Patent Document 1, although the dripper is not fixed to the cup by the locking structure, it is possible to obtain a locking feeling as if the dripper was fixed to the cup. However, when removing the dripper from the top of the cup after brewing coffee, etc., it is necessary to insert your fingers between the support and the filter and pick up the support. There is a risk of it getting dirty. Furthermore, in order to secure a space between the support and the filter, it is necessary to reduce the size of the filter opening. As a result, the capacity of the dripper becomes smaller, it becomes difficult to pour hot water into the filter, and coffee, etc., splashes outside the filter.

The present invention was made in view of the above circumstances, and its purpose is to fix the support shape in a cylindrical open state and to easily lift the filter even if the filter opening is large. Our goal is to provide a dripper that can.

In order to achieve the above object, a dripper of a first invention is a dripper having a bag-shaped filter and a cylindrical support formed to be foldable with the filter located inside. ,
The cylindrical support has a first opening constituting one opening, a second opening constituting the other opening, and the support shape is changed to a cylindrical open state by a crease on the first opening side. It has a locking structure that secures it to the
The opening of the filter is attached to the first opening so that the filter opens when the support is changed from a folded state to a cylindrical open state,
The lock structure is characterized in that protrusions are formed on the lock structure so as to protrude higher than the opening of the filter from both sides of the mounting position of the opening of the filter.

In the dripper of a second invention, in the first invention, the lock structure includes a first fold formed from the first opening to the second opening on both sides of the support in the folded state. , second and third folds formed to intersect with the first fold,
the protrusion is located closer to the first opening than the third fold;
the second fold intersects with the first fold on a side closer to the second opening than the third fold;
The second fold has a pair of symmetrical curved shapes with respect to the first fold, and the third fold has a pair of linear shapes symmetrical with respect to the first fold.

In the dripper of a third invention, in the second invention, the second fold is formed in a mountain fold toward the outside of the support, so that the support shape is fixed in a cylindrical open state. It is characterized by being

A dripper according to a fifth invention is characterized in that, in any one of the first to fourth inventions, the support body is formed of a single bent blank plate.

A dripper according to a sixth invention is characterized in that, in any one of the first to fifth inventions, a content having a component to be extracted is enclosed in the filter.

According to the present invention, the support body shape can be fixed in the cylindrical open state with the lock structure. The locking structure has protrusions that protrude higher than the filter opening from both sides of the filter opening installation position, so even if the filter opening is large, the dripper can be easily gripped by the protruding parts. Can be lifted. Therefore, when holding the dripper, the user's hands will not be soiled with coffee or the like, and the capacity of the dripper can be increased. Furthermore, since the filter opening can be made larger, it becomes easier to pour hot water into the filter, and it is also possible to prevent coffee, etc. from splashing out of the filter with the protrusion.

FIG. 2 is an external view showing an embodiment of a dripper before and after opening. FIG. 2 is an external view of the dripper shown in FIG. 1 in a used state after opening. FIG. 2 is a plan view showing a blank plate of a support that constitutes the dripper of FIG. 1;

DESCRIPTION OF THE PREFERRED EMBODIMENTS Drippers and the like according to embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the appearance of the dripper 1 before and after opening, and FIG. 2 shows the appearance of the dripper 1 set on the cup 17 in the used state after opening. In FIG. 1, (A) is a front view showing the appearance of the dripper 1 in an unopened state (the support body 3 is folded), and (B) is a front view showing the appearance of the dripper 1 in the unsealed state (the cylindrical shape of the support body 3). FIG. 2, (A) is a top view of the dripper 1, (B) is a front view of the dripper 1, and (C) is a side view of the dripper 1.

The dripper 1 includes a bag-shaped filter 2 and a cylindrical support (sleeve-shaped mount) 3 that is foldable with the filter 2 located inside. This dripper 1 is suitable for portability because the support body 3 is foldable, and is suitable for disposable use because it has a simple structure that can be constructed from materials that are easy to dispose of. In other words, although it is a portable and disposable type, it has the advantage of being able to easily brew drip coffee, for example.

The contents 18 (FIG. 2(A); for example, regular coffee powder, black tea leaves, green tea leaves, etc.) having components to be extracted are stored in the filter 2 during use, or are sealed in the filter 2 in advance. be done. When the contents 18 are sealed in the filter 2 in advance, the opening 9a of the filter 2 is peeled off by ultrasonic sealing via the support 3 to prevent the contents 18 from spilling out of the filter 2 before using the dripper 1. Possibly closed.

The material for the filter 2 may be a sheet material that has heat adhesive properties, a sheet material that has heat adhesive properties on one side (the innermost layer when it is made into a bag shape), etc., in consideration of processability when making it into a bag shape. It is preferable to use For example, water-permeable nonwoven fabric made of polyolefin-based (polyethylene, polypropylene, etc.), polyester-based material, etc., thermoplastic resin such as polyolefin-based (polyethylene, polypropylene, etc.), polyester-based material on one side (innermost layer when made into a bag) Examples include filter paper with a multilayer structure containing . The bag-shaped processing is performed by folding the sheet materials in half or gusset-folding the sheet materials, stacking them, thermally adhering them into a predetermined shape, and cutting and die-cutting them.

The cylindrical support 3 allows the filter 2 to be set on the cup 17 (FIG. 2) while maintaining the filter 2 in a predetermined shape. As shown in FIGS. 1 and 2, this support body 3 has a first opening 7 forming one opening 7a, a second opening 8 forming the other opening 8a, and a side of the first opening 7. A locking structure 20 for fixing the shape of the support 3 in a cylindrical open state at the folds M1 to M3 is provided.

The lock structure 20 includes a first fold M1 formed by folding and second and third folds M2 and M3 formed by pushing. The first fold M1 is formed from the first opening 7 to the second opening 8 on both sides of the support 3 in the folded state (FIG. 1(A)). Second and third folds M2 and M3 are formed so as to intersect with the first fold M1 (Fig. 1(B)), and the second fold M2 is larger than the third fold M3. It intersects with the first fold M1 on the second opening 8 side. Further, the second fold M2 has a pair of curved shapes that are symmetrical with respect to the first fold M1, and the third fold M3 has a pair of linear shapes that are symmetrical with respect to the first fold M1. (Figure 2(C)). Then, the second fold M2 is formed in a mountain fold toward the outside of the support 3, thereby fixing the shape of the support 3 to the cylindrical open state. Moreover, by forming the third fold M3 in a valley fold toward the inner side of the support body 3, the shape fixation of the support body 3 and the locking feeling are strengthened.

The first opening 7 has a filter opening 9 so that the filter 2 opens when the support 3 is changed from the folded state (FIG. 1(A)) to the cylindrical open state (FIGS. 1(B) and 2). (Fig. 2(A)) is attached. The filter 2 is attached by inserting the filter 2 into the support 3, folding it back outward at the edge of the first opening 7 of the support 3, and pasting the folded portion onto the outer surface of the support 3. . When the filter 2 is attached in this way, when the support body 3 is opened into a cylindrical state (Fig. 1 (B), Fig. 2) during use, the filter 2 opens wide and becomes a state suitable for pouring and dripping. Become. Furthermore, protrusions 11 are formed in the lock structure 20 so as to protrude higher than the filter opening 9 from both sides of the attachment position of the filter opening 9. This protrusion 11 is located closer to the first opening 7 than the third fold M3.

The support body 3 is formed by bending, gluing, etc. one blank plate 3A shown in FIG. FIG. 3 is a developed view of the support body 3, and the blank plate 3A is formed by punching out a plate-shaped sheet material as shown in the developed view (FIG. 3). The material of the blank board 3A is not particularly limited, but for example, cardboard such as waterproof card paper or ivory paper, or cardboard coated with resin (polyethylene, etc.) on both sides (particularly the inner surface of the support 3) may be used. It can be used as a sheet material. Note that if the blank board 3A is made of cardboard coated with resin, even if the support body 3 is exposed to hot water or steam, a decrease in its rigidity can be prevented.

The blank plate 3A (FIG. 3) is composed of three parts having the bending line L1 as a boundary, that is, a front plate 4, a back plate 5, and a glue margin piece 6. The front plate 4 is provided with a protrusion 11; legs 12, 13; a substantially trapezoidal hole 16; bending lines L2, L3, etc., symmetrically provided. When the adhesive strip 6 is adhered to the back plate 5, the same shape as the front plate 4 can be obtained symmetrically about the bending line L1. The protrusion 11 is located at a portion corresponding to the first opening 7 (FIG. 1, etc.) of the support 3, and the legs 12, 13 are located at a portion corresponding to the second opening 8 (FIG. 1, etc.) of the support 3. The hole 16 is located between the portions corresponding to the first and second openings 7 and 8.

Specific examples of the folding lines L1 to L3 include ruled lines such as pressed lines, cut lines, perforation lines, lead rules, etc. Here, a pressed line is assumed as the folding line L1, and the folding lines L2 and L3 are It is assumed that the cut is partially provided with a connecting part (blade stop part).

When assembling the support body 3, first, the blank plate 3A is bent along the bending line L1 at the boundary between the front plate 4 and the back plate 5, so that the front plate 4 and the back plate 5 are overlapped. Next, the blank board 3A is bent along the bending line L1 at the boundary between the front plate 4 and the adhesive strip 6, so that the adhesive strip 6 overlaps the back panel 5. When the adhesive piece 6 is adhered to the back plate 5 in this state, the blank plate 3A becomes cylindrical and the support body 3 in a folded state is obtained. Furthermore, when the filter 2 is attached within the support body 3, the folded dripper 1 (FIG. 1(A)) is obtained as described above.

By bending the blank plate 3A along each bending line L1, a crease M1 (FIG. 1(A)) is formed at the position of each bending line L1. When the upper portions of the left and right fold lines M1 (portions closer to the first opening 7 than the fold line L2) are pressed in a direction toward each other on the folded support body 3, force is concentrated on the fold lines L1 to L3. Therefore, the blank plate 3A can be easily bent along the bending lines L1 to L3. By this bending, creases M2 and M3 are formed at the positions of the respective bending lines L2 and L3, and as shown in FIG. Square openings 7a and 8a are formed. Then, the support body 3 becomes a cylindrical open state (see FIG. 2, etc.), and a substantially hexagonal opening 9a is also formed in the filter opening 9. Note that by gusseting the bottom of the filter 2, it is possible to effectively increase the capacity of the dripper 1.

The folds M1 to M3 formed as described above function as a lock structure 20 that fixes the shape of the support body 3 in the cylindrical open state. The main part of the lock structure 20 is a first fold M1 formed from the first opening 7 to the second opening 8 on both sides of the support 3 in the folded state (FIG. 1(A)), These are second and third folds M2 and M3 formed to intersect with the fold M1 (FIG. 2(C)). As described above, when the upper portions of the left and right folds M1 are pressed in the direction toward each other, the intersection of the first valley fold M1 and the second mountain fold M2 will reach the apex toward the outside of the support 3. The support 3 is formed by folds M1 to M3 such that the intersection of the first mountain fold M1 and the third valley fold M3 forms an apex toward the inside of the support 3. It becomes bent. At this time, a locking feeling occurs, and at the same time, the shape of the support body 3 is fixed in the cylindrical open state.

Since the second and third folds M2 and M3 have linear shapes convex toward the second opening 8 side symmetrically with respect to the first fold M1, the folds M2 and M3 are formed by pressing at the fold M1. This can be done neatly along the bending lines L2 and L3. Moreover, it is preferable that at least one of the second and third folds M2 and M3 has a notch at a position intersecting with the first fold M1. The incisions make it possible to more firmly lock the shape of the support 3.

As shown in FIGS. 2(B) and 2(C), the second opening 8 of the support body 3 assembled as described above has a pair of legs 12 facing each other via the opening 8a, and an opening. A pair of leg portions 13 are formed that face each other via 8a. When the support body 3 is opened into a cylindrical state by bending the blank plate 3A along the bending lines L1 to L3, the leg portions 12 and 13 are placed at predetermined positions in the second opening 8. That is, in the folded state of the support 3 (FIG. 1(A)), the legs 12 are provided at the bending positions (positions where the crease M1 is formed) on both sides, and the legs 13 are provided between the two legs 12. It will be done. Since the legs 12 and 13 are arranged in a well-balanced manner in the second opening 8 of the support 3, the center of gravity of the dripper 1 is lowered as a whole and stabilized.

When using the dripper 1, for example when brewing coffee, the support body 3 is changed from the folded state (FIG. 1(A)) to the cylindrical open state ( After opening the filter 2 as shown in Figs. 1(B) and 2), place the dripper 1 on the cup 17, and pour regular coffee powder into the filter 2 as the content 18 (Fig. 2(A)). do. In the case of a type in which regular coffee powder is pre-filled in the filter 2, the filter 2 is unsealed and the support 3 is changed from a folded state to a cylindrical open state, and then a dripper is placed on the cup 17. In either case, when hot water is poured into the filter 2 through the opening 9a, the extracted coffee will pass through the filter 2 and accumulate in the cup 17.

When the dripper 1 with the support body 3 in the cylindrical open state is placed on the cup 17 as described above, the leg portion 13 will be located inside the edge of the cup 17, as shown in FIG. The leg portion 12 is located outside the second opening 12. Since the legs 12 and 13 are arranged in a well-balanced manner inside and outside the cup 17, even a large-capacity dripper 1 can be maintained in a stable state. Since the dripper 1 is not fixed to the cup 17, the degree of freedom in arranging the legs 12, 13 relative to the edge of the cup 17 is increased, making it possible to accommodate cups of various diameter sizes. In addition, if the shape of the leg part 12 is adjusted by providing a notch or the like at the base of the leg part 12, the position of the cup 17 relative to the edge can be properly regulated.

By pouring a predetermined amount of hot water into the filter 2 through the opening 9a as described above, a beverage (coffee, black tea, green tea, etc.) from which desired components have been extracted from the contents 18 in the filter 2 is poured into the cup 17. can be obtained. For example, even if hot water is poured into the filter 2 and coffee splashes out of the filter 2, it is blocked by the protrusion 11, so the table etc. will not be soiled by the coffee splashed out of the dripper 1. Since the inside of the cup 17 can be seen through the hole 16, the amount of coffee inside the cup 17 can be easily checked while pouring hot water.

When extraction of coffee or the like is completed, the dripper 1 is removed from the top of the cup 17 by pinching the two protrusions 11. Since it is not necessary to insert a finger between the filter 2 and the support 3, there is no need to secure a space between the filter 2 and the support 3, and a filter 2 with a large opening 9a can be used. Since the protrusion 11 is separated from the filter 2, the user's hands will not get dirty with coffee or the like and will not feel hot.

As described above, according to this embodiment, the shape of the support body 3 can be fixed in the cylindrical open state by the lock structure 20. The locking structure 20 is formed with protrusions 11 that protrude higher than the filter opening 9 from both sides of the attachment position of the filter opening 9, so even if the opening 9a of the filter 2 is large, the protrusions 11 can be You can easily lift the dripper 1 by picking it up. Therefore, when holding the dripper 1, the user's hands will not be soiled with coffee or the like, and the capacity of the dripper 1 can be increased. Furthermore, since the opening 9a of the filter 2 can be enlarged, hot water can be easily poured into the filter 2, and the protrusion 11 can prevent coffee or the like from splashing outside the filter 2.
