Description

[Technical Field]

[0001] The present invention relates to a dripper that stores contents containing components to be extracted and filters the contents. [Background technology]

[0002] Patent Document 1 discloses a dripper used to store and strain contents containing ingredients to be extracted, such as ground regular coffee, black tea leaves, or green tea leaves. This dripper includes a support body made of a paper cylinder with openings on the top and bottom, and a bag-like filter that encloses the contents. The support body is formed into a flat plate whose width is greater than its height by folding along fold lines on both sides. The filter has its upper end bonded to the support body, and the top opening is releasably bonded and sealed by ultrasonic welding.

[0003] When the flat support is opened into a cylindrical shape, the filter peels off the adhesive and is unsealed. By placing the support on a cup and pouring hot water through the filter's top opening, the extractable components are extracted and the liquid flows down into the cup. At this time, multiple engaging protrusions on the bottom of the support, located on the inside and outside of the cup, engage with the upper edge of the cup, maintaining the dripper's position.

[0004] [Patent Document 1] JP 2004-711 A (pages 4 to 8, Figure 1) Summary of the Invention [Problem to be solved by the invention]

[0005] However, the conventional drippers described above have a problem of poor stability when placed on a cup during pouring.

[0006] An object of the present invention is to provide a dripper that can improve stability when pouring hot water. [Means for solving the problem]

[0007] To achieve the above object, the present invention provides a dripper that is placed on a cup and includes a cylindrical support body having a pair of opposing plates, and a filter disposed inside the support body for enclosing contents having components to be extracted. The dripper is characterized by the following: a skirt portion whose upper end is connected to each of the opposing plates and whose lower end can be folded outward; and a folding piece whose opposite ends are formed by first notches extending upward from both ends of a folding line extending in the left-right direction on each of the skirt portions and which can be folded back along the folding line.

[0008] In the dripper of the present invention having the above-described structure, at least the upper portions of both side edges of the skirt portion are formed by a pair of second cutouts extending upward from the lower end of the opposing plate.

[0009] Furthermore, in the dripper of the present invention having the above-described structure, the upper end of the second cutout is formed in an inwardly convex curve.

[0010] In the dripper of the present invention having the above-described structure, the lower end of the skirt portion protrudes downward beyond the lower end of the opposing plate.

[0011] Furthermore, in the dripper of the present invention having the above-described configuration, the folding line is formed to be convex downward.

[0012] In the dripper of the present invention having the above-described structure, the lower end of the first cutout is formed in an R-shape so as to be connected to both ends of the folding line.

[0013] Furthermore, in the dripper of the present invention having the above-described structure, there are provided locking portions that protrude downward from the lower end of the opposing plate and are disposed on both sides of the skirt portion. [Effects of the Invention]

[0014] According to the present invention, a folding piece is formed on the foldable skirt portion by a first incision extending from both ends of the folding line. This allows the skirt portion to bend outward from the support placed on the cup, and the folding piece is folded back from the skirt portion. The pair of folding pieces elastically clamp the cup, maintaining the support placed on it. This improves the stability of the dripper when pouring hot water. [Brief explanation of the drawings]

[0016] First Embodiment Embodiments of the present invention will be described below with reference to the drawings. Figs. 1 and 2 show a front view and a side cross-sectional view of a dripper according to a first embodiment. Dripper 1 includes support 10, which is a paper cylinder, and filter 20 inserted into support 10. Filter 20 has a filtering function and contains contents D containing components to be extracted, such as regular coffee powder, black tea leaves, or green tea leaves.

[0017] The cylindrical support body 10 is open at the top and bottom and is folded at fold lines 10a (see Figure 3) on both sides, forming a pair of opposing plates 11, 12 facing each other in the front and rear, forming a flat plate. The flat support body 10 is roughly fan-shaped when viewed from the front. Windows 17 are opened on the opposing plates 11, 12, allowing the pouring state of the molten metal into the filter 20 to be visually observed.

[0018] The support body 10 is provided with a skirt portion 14 that protrudes downward from the opposing plates 11, 12. The upper portions of both side edges of the skirt portion 14 are formed by notches 14a (second notches) provided in the opposing plates 11, 12. This allows the skirt portion 14 to be connected at its upper end to the opposing plates 11, 12 and bend at its lower end outward. An inwardly convex curved relief portion 14b is provided at the upper end of the notch 14a. Relief portion 14b prevents the upper end of the skirt portion 14 from tearing when it is bent.

[0019] The lower end of the skirt portion 14 may be flush with the lower ends of the opposing plates 11 and 12, or may be located higher than the lower ends of the opposing plates 11 and 12.

[0020] A folded piece 15 is provided inside the skirt portion 14, surrounded by a fold line 15a and a notch 15b (first notch). The fold line 15a extends in the left-right direction and curves downward convexly. The notches 15b are formed convexly upward and extend upward from both ends of the fold line 15a, forming both side ends and the top end of the folded piece 15. This allows the folded piece 15 to be folded back on the fold line 15a. At the bottom end of the notch 15b, an R-shaped relief portion 15c is provided that connects to both ends of the fold line 15a. The relief portion 15c prevents tearing at both ends of the fold line 15a when the folded piece 15 is folded back.

[0021] The filter 20 is formed in a bag shape from a water-permeable nonwoven fabric made of a thermoplastic resin such as polyolefin (polyethylene, polypropylene, etc.) or polyester. The filter 20 is formed by heat-bonding both side edges of sheets of nonwoven fabric, etc., facing each other from the front and back. A gusset (not shown) is provided at the bottom end of the filter 20.

[0022] A pair of front and rear adhesive pieces 24 are provided at the center of the upper end of filter 20. Filter 20 is fixed to support 10 by folding adhesive pieces 24 back onto the outer surface of protruding portion 16 protruding from the center of the upper end of support 10 and adhering them at adhesive portion E. After filling the upper end of filter 20 with contents D, it is sealed at sealing portion 26 by ultrasonic welding or the like.

[0023] FIG. 3 shows a development view of a blank plate 30 that forms the support 10. The blank plate 30 has a paper base layer on one side of which a print layer with a pattern or the like is provided. The paper base layer has a thickness of 200 to 340 g / m 2 The printing layer is disposed on the outer surface of the support 10 made of a cylindrical body, and the paper base layer is exposed on the inner peripheral surface of the support 10.

[0024] Alternatively, a protective layer such as polyethylene may be provided on the outer surface of the paper substrate layer, and the printing layer may be formed on the protective layer. The protective layer can improve the water resistance of the outer surface of the support 10 and the printing properties of the printing layer.

[0025] The blank plate 30 has an opposing plate 12 and an adhesive strip 12a connected in this order via a folding line 10a on one side of the opposing plate 11. The opposing plates 11 and 12 have their opposite ends inclined downwards so that they approach each other.

[0026] Windows 17 are provided on the opposing plates 11 and 12. Protrusions 16 are provided at the center of the upper ends of the opposing plates 11 and 12 so as to protrude upward. Skirts 14 are formed below the windows 17 of the opposing plates 11 and 12 by cuts 14a that face each other on the left and right. The lower ends of the skirts 14 protrude from the lower ends of the opposing plates 11 and 12.

[0027] The blank plate 30 is folded over along both fold lines 10a, and the opposing plate 11 and the adhesive tab 12a are bonded together. This forms a flat support 10 made of a cylindrical body having opposing opposing plates 11 and 12. The adhesive used to bond the opposing plate 11 and the adhesive tab 12a can be selected from a variety of adhesives, including hot-melt, solvent, water-based, reactive, and pressure-sensitive types.

[0028] 4 and 5 are a perspective view and a side cross-sectional view showing dripper 1 in use. When dripper 1 is used, fold-back piece 15 is folded back from above skirt portion 14. Next, by grasping protruding portion 16 of support 10 of dripper 1 and pulling it back and forth, adhesive portion 26 of filter 20 is peeled off, opening the top surface of filter 20.

[0029] After removing the filter 20, the dripper 1 is grasped by the lower end of the skirt portion 14 and spread outward, and the skirt portion 14 is placed on the cup 2. At this time, the pair of folded pieces 15 elastically hold the cup 2. This keeps the support 10 in place, and the dripper 1 is stably fixed on the cup 2.

[0030] Furthermore, since folding line 15a (see FIG. 1) at the lower end of folding piece 15 is formed to be convex downward, the tip of folding piece 15 exerts a stronger pressure on cup 2. This allows dripper 1 to be more stably fixed on cup 2.

[0031] When an appropriate amount of hot water is poured into the top opening of the filter 20, the extracted liquid of the contents D flows down into the cup 2. Then, the dripper 1 is removed and the extracted liquid in the cup 2 can be drunk.

[0032] In this embodiment, folded pieces are formed on the bendable skirt portion 14 by incisions 15b (first incisions) extending from both ends of the folding line 15a. As a result, the skirt portion 14 is bent outward from the support 10 placed on the cup 2, and folded pieces 15 are folded back from the skirt portion 14. The pair of folded pieces 15 elastically hold the cup 2 in place, maintaining the support 10 in a placed position. This improves the stability of the dripper 1 when pouring hot water.

[0033] In addition, the upper portions of both side ends of the skirt portion 14 are formed by a pair of notches 14a (second notches) extending upward from the lower ends of the opposing plates 11, 12, making it easy to realize a skirt portion 14 whose upper end is connected to the opposing plates 11, 12 and whose lower end can be bent outward.

[0034] Furthermore, since the cutout 14a (second cutout) has an inwardly curved relief portion 14b at its upper end, the relief portion 14b can prevent the upper end from tearing when the skirt portion 14 is bent.

[0035] Furthermore, since the lower end of the skirt portion 14 protrudes downward further than the lower ends of the opposing plates 11 and 12, the skirt portion 14 can be widely spread outward from the opposing plates 11 and 12. This makes it easy to realize the folded piece 15 disposed on the outside of the cup 2.

[0036] Furthermore, since folding line 15a at the lower end of folding piece 15 is formed to be convex downward, the force with which the tip of folding piece 15 presses cup 2 is increased. This allows dripper 1 to be fixed more stably on cup 2.

[0037] Furthermore, the lower ends of the cuts 15b (first cuts) are formed in an R-shape that is connected to both ends of the folding line 15a, so that tearing of both ends of the folding line 15a when the folded-back piece 15 is folded back can be prevented.

[0038] Second Embodiment Next, Fig. 6 shows a front view of dripper 1 of a second embodiment. Fig. 7 shows a development view of blank plate 30 forming support 10. For ease of explanation, the same parts as those of the first embodiment shown in Figs. 1 to 5 are designated by the same reference numerals. In dripper 1 of this embodiment, opposing plates 11 and 12 of support 10 are generally rectangular in front view. Other parts are the same as those of the first embodiment.

[0039] As in the first embodiment, the blank plate 30 has an opposing plate 12 and an adhesive strip 12a connected in this order to one side of the opposing plate 11 via a folding line 10a. The opposing plates 11 and 12 have their opposite ends formed parallel to one another.

[0040] This embodiment can also achieve the same effects as the first embodiment. Furthermore, the opposing plate 11 is formed in a substantially rectangular shape with parallel fold lines 10a at both side edges. Therefore, the direction in which the opposing plates 11 and 12 are aligned coincides with the folding direction, and the support body 10 can be easily formed using an assembly device that folds the blank plate 30.

[0041] Third Embodiment Next, FIG. 8 shows a front view of dripper 1 of a third embodiment. FIG. 9 shows a development view of blank plate 30 forming support 10. For ease of explanation, the same reference numerals are used for parts similar to those of the second embodiment shown in FIGS. 6 and 7. In dripper 1 of this embodiment, support 10, which is generally rectangular when viewed from the front, has a longer width than that of the second embodiment. Furthermore, engaging portions 13 are provided at the lower ends of opposing plates 11 and 12 of support 10. The other parts are similar to those of the first embodiment.

[0042] A portion of the opposing plate 12 of the blank plate 30 is connected to one side of the opposing plate 11 via a fold line 10a, and a glue tab 12a is connected to the other side via a fold line 10a. In Figure 9, the right side of the glue tab 12a forms part of the opposing plate 12, and the left side forms an adhesive region 12b. By adhering the adhesive region 12b to the opposing plate 12 arranged on one side of the opposing plate 11, the opposing plates 12 on both sides are connected, and an opposing plate 12 overlapping the opposing plate 11 is formed. At this time, both side edges of the opposing plates 11 and 12 are formed parallel to each other.

[0043] A skirt portion 14 similar to that of the second embodiment is formed below the window portion 17 of the opposing plates 11, 12. The folded piece 15 provided inside the skirt portion 14 is surrounded by a folding line 15a, a notch 15b (first notch), and the window portion 17. The folding line 15a extends in the left-right direction and curves downward convexly. The notches 15b extend upward from both ends of the folding line 15a and are connected to the window portion 17. The notches 15b form both side ends of the folded piece 15, and the window portion forms the upper end of the folded piece 15.

[0044] At the lower ends of the opposing plates 11, 12, engaging portions 13 are provided adjacent to both sides of the skirt portion 14 and protruding downward. The engaging portions 13 are separated from the skirt portion 14 by notches 14a. In addition, at both end portions of the opposing plates 11, 12, leg portions 18 are provided that protrude downward from the lower ends of the opposing plates 11, 12.

[0045] 10 and 11 are a perspective view and a side cross-sectional view showing dripper 1 in use. After filter 20 is removed, dripper 1 is spread outward by grasping the lower end of skirt portion 14, and opposing plates 11 and 12 are placed on cup 2. Because the straight portions of the lower ends of opposing plates 11 and 12 are long, opposing plates 11 and 12 can be easily placed on cup 2, even if the cup 2 is large.

[0046] The tip of the skirt portion 14 is disposed outside the cup 2, and a pair of folded pieces 15 hold the cup 2 in place by their elasticity.

[0047] Furthermore, locking portion 13 is disposed along the inner peripheral surface of cup 2, and support 10 is locked by locking portion 13. Legs 18 are disposed facing the outer peripheral surface of cup 2. This maintains support 10 in a placed state, and dripper 1 is stably fixed onto cup 2.

[0048] This embodiment can achieve the same effects as the second embodiment. Furthermore, as in the first and second embodiments, when the cup 2 is large, the skirt portion 14 is placed on the cup 2 to support the support 10. Therefore, when hot water is poured into the filter 20, the filter 20 may drop and become submerged in the extracted liquid in the cup 2. However, in the dripper 1 of this embodiment, the width of the support 10 is large, so the opposing plates 11 and 12 can be placed to support the support 10 even if the cup 2 is large. This prevents the filter 20 from becoming submerged in the extracted liquid in the cup 2.

[0049] Furthermore, locking portions 13 are provided on both sides of skirt portion 14, protruding downward from the lower ends of opposing plates 11 and 12, so that support body 10 is locked by locking portions 13 arranged along the inner peripheral surface of cup 2. This allows dripper 1 to be stably fixed on cup 2.

[0050] Furthermore, legs 18 are provided that protrude downward from the lower ends of both side edges of opposing plates 11, 12, so that dripper 1 can be more stably fixed on cup 2 by legs 18 that are arranged facing the outer circumferential surface of cup 2.

[0051] <Fourth embodiment> Next, FIG. 12 shows a development view of blank plate 30 forming support 10 of dripper 1 of the fourth embodiment. For ease of explanation, the same parts as those of the third embodiment shown in FIGS. 8 to 11 are designated by the same reference numerals. In dripper 1 of this embodiment, both side edges of support 10 are inclined, similar to the first embodiment (see FIG. 1), and the width of the approximately fan-shaped support 10 is longer than that of the first embodiment. Other parts are the same as those of the third embodiment.

[0052] According to this embodiment, as in the third embodiment, the width of the support 10 is large, so that even if the cup 2 is large, the opposing plates 11 and 12 can be placed on the support 10 to support it. This prevents the filter 20 from being immersed in the extract in the cup 2.

[0053] Fifth Embodiment Next, Figure 13 shows a development view of blank plate 30 forming support 10 of dripper 1 of the fifth embodiment. For ease of explanation, the same parts as those of the third embodiment shown in Figures 8 to 11 are designated by the same reference numerals. Dripper 1 of this embodiment is provided with locking portions 19 on both side ends of support 10. Other parts are the same as those of the third embodiment.

[0054] The opposing plate 12 is divided into left and right halves and is arranged on both sides of the opposing plate 11. A part of the opposing plate 12 is connected to one side of the opposing plate 11 via a folding line 10a, and an adhesive piece 12a is connected to the other side via the folding line 10a. By adhering the adhesive region 12b to the opposing plate 12 arranged on one side of the opposing plate 11, the opposing plates 12 on both sides are connected, and an opposing plate 12 overlapping the opposing plate 11 is formed.

[0055] Locking portions 19 are arranged on both folding lines 10a. Locking portions 19 are formed symmetrically with respect to folding line 10a and are provided between upper notch portions 19a and lower notches 19b. Notch portions 19a are formed in an arch shape symmetrical with respect to folding line 10a, and notches 19b are formed in a straight line intersecting folding line 10a. Folding lines 19c extending the arcs on the periphery of notch portions 19a are provided on both side ends of locking portion 19, and folding line 19d extending folding line 10a is provided in the center.

[0056] 14 is a perspective view showing dripper 1 in use. When locking portion 19 of support body 10 formed by blank plate 30 is pushed inward by fold line 19d, support body 10 is held in a cylindrical shape. Cutout portion 19a may be formed by a notch, and cutout 19b may be formed by a notch. Cutout 19b may also be formed in a curved shape.

[0057] According to this embodiment, the same effects as those of the third embodiment can be obtained. In addition, since the support 10 has the locking portion 19, the support 10 can be held in a cylindrical shape. Therefore, the upper surface of the filter 20 is kept wide open, making it easy to pour hot water.

[0058] The locking portion 19 similar to that of this embodiment may be provided in the first, second or fourth embodiment. [Industrial Applicability]

[0059] The present invention can be used in drippers for regular coffee, black tea, green tea, etc. [Explanation of symbols]
