Description

[Technical field]

[0001] The present invention relates to a dual-use coffee filter hanging structure that is hung on a container to extract coffee, and in particular, to a dual-use coffee filter hanging structure that can be fixed on the container in a normal or diagonal hanging manner according to various needs, allowing users to select the coffee extraction mode themselves. [Background technology]

[0002] In filter or ear-mounted coffee brewing, a filter paper containing ground coffee powder is suspended over the mouth of a cup, and the user adds hot water to steep the coffee, extracting the coffee's attractive flavor and aroma and achieving the purpose of tasting the coffee.

[0003] In the prior art, filter paper is made into two types of drip bags, roughly square drip bags and funnel drip bags, depending on the brewing method, and the flavor produced is completely different depending on the brewing time and method. The drip methods of square drip bags and funnel drip bags are explained below.

[0004] The drip bag is roughly rectangular in shape and has a water inlet at the top. The loop is hung over the mouth of a cup. The inlet at the top of the drip bag is opened and hot water is added to soak the ground coffee. Since the bottom of the drip bag is elongated, the time the hot water is in contact with the ground coffee can be extended, allowing the user to control the amount of time the hot water is in contact with the ground coffee, thereby extracting coffee of different strengths that are full of flavor and aroma.

[0005] The water inlet at the top of the funnel-shaped drip bag has a larger area than the bottom, so that the extracted coffee liquid falls directly into the cup, greatly shortening the time that the hot water comes into contact with the coffee powder, achieving the purpose of quickly extracting coffee in a short time and making the coffee taste refreshing.

[0006] However, since the filter coffee products currently on the market are already designed to use drip bags, no matter what type of drip bag a user purchases, they are forced to brew coffee according to the type of drip bag they purchased, and they cannot change the drip mode of the drip bag.

[0007] Prior art filter-hanging or ear-hanging devices are made of paper and use a simple recess to provide the hanging mechanism. However, because the paper material itself is elastic, the recess may come off the cup mouth, resulting in a less than ideal hanging effect. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention designs a number of structures on the ear hook structure that can be pulled, folded or unfolded, and by using the structures, the drip bag can be engaged with the cup mouth of the container in a normal or diagonal manner. When the drip bag is engaged in the normal manner, the water inlet at the top of the drip bag can be opened, the drip bag can be hung normally on the cup mouth of the container, and a coffee filter can be hung to extract. When the funnel drip bag mode is used for extraction, at least one adjacent side of the water inlet at the top is opened to form a funnel-shaped filter paper, and the filter paper can be hung diagonally on the cup mouth of the container and a coffee filter can be hung to extract. Therefore, the present invention changes the hook method of the ear hook structure to a different one, allowing the user to choose whether to use a square drip bag to extract coffee, or to change the drip bag from a square drip bag to a funnel drip bag to extract coffee.

[0009] In the present invention, in order to increase the stability of the hanging hook, an additional engagement structure may be designed for the hanging hook structure. [Means for solving the problem]

[0027] The dual-use coffee filter hanging structure of the present invention, as shown in the plan view of the overall structure in Figures 1 and 2, includes at least a drip bag 1 and ear hooking devices 2 (both sides are symmetrical, and only one side is shown in the figure) installed on each of the two sides of the drip bag 1. The drip bag 1 is used to fill the bag with coffee extract. The ear hooking device 2 is used to fix the bag to a cup, and when water is added to the drip bag 1, coffee can be extracted into the cup.

[0028] As shown in Fig. 1 to Fig. 5, a drip bag 1 has a chamber 11 in it. A water inlet 12 is opened on one side of the drip bag 1. A tearable seal edge 121 is provided on the water inlet 12. After tearing open the seal edge 121, the water inlet 12 is opened and used in a normal hanging position. A tear edge 13 is provided on one or both sides of the water inlet 12. The tear edge 13 is preferably sealed using high frequency. Each tear edge 13 is in a sealed state under normal conditions, and when used, one is selected and torn, and the torn tear edge 13 communicates with the water inlet 12 to form a larger opening, and used in a diagonal hanging position. The above-mentioned normal hanging and diagonal hanging may be combined with the ear hanging device 2, which will be described in detail below together with the ear hanging device 2.

[0029] As shown in Fig. 1, the ear hanging device 2 is formed by cutting a piece of material 20 along multiple cutting lines 201, and multiple blocks are formed on the piece of material 20 along each cutting line 201, which can be pulled, folded or unfolded. Depending on the different design of each cutting line 201, each block has a different shape and hanging effect. Therefore, the different designs are shown in four different embodiments in this text, which will be described in detail below.

[0030] In the first embodiment of the ear hanging device, as shown in Figs. 2 to 5, the blocks are fixed parts 21 provided inside the ear hanging device 2. The fixed parts 21 have connecting parts 22 extending upward. First convex ends 221 extending outward are provided on both sides of the connecting parts 22. An inner ring part 23 extends above the connecting parts 22. The inner ring part 23 covers the peripheries of the fixed parts 21 and the connecting parts 22. Second convex ends 231 are respectively provided to protrude inward at locations facing the first convex ends 221 on both sides of the inner ring portion 23. An inner engagement groove 24 that is not completely sealed is formed at a location adjacent to the connecting portion 22 of the inner ring portion 23, and between the first convex end 221 and the second convex end 231 adjacent to the inner engagement groove 24, the first convex end 221 and the second convex end 231 are each designed to be pyramidal in terms of outline design, with the pyramidal sides of the first convex end 221 and the second convex end 231 positioned on both lower sides of each inner engagement groove 24, and the upper part of each inner engagement groove 24 is designed to be a rhombus by combining the pyramidal sides.

[0031] The outer ring portion 25 is provided on the outside of the inner ring portion 23. On both sides of the outer ring portion 25, a first outer engagement groove 26 is formed facing outward. A third convex end 261 is adjacent to the first outer engagement groove 26. The outer ring portion 25 fixes (adheres) the remaining area and the fixing portion 21 to the two side surfaces of the drip bag 1, in addition to the area around the first outer engagement groove 26 and the third convex end 261. In terms of the design of the outline, the first outer engagement groove 26 is formed in an inclined U-shape, and the inclination direction is such that the upper part faces outward and the lower part faces inward, and the third convex end 261 is designed in a cone shape. The inner ring portion 23 extends a pull-out portion 232 outward away from the inner engagement groove 24, and the pull-out portion 232 forms a dividing portion 251 in the outer ring portion 25. The dividing portion 251 is located between the two first outer engagement grooves 26.

[0032] In a specific positional arrangement, the two inner engagement grooves 24 are close to the water inlet 12, and the two first outer engagement grooves 26 are far from the water inlet 12, and the two inner engagement grooves 24 and the two first outer engagement grooves 26 are arranged corresponding to each other vertically.

[0033] A number of protrusions 233 are provided extending from the outer side of the inner ring portion 23. By providing each protrusion 233, a corresponding recess 252 is provided on the inner side of the outer ring portion 25.

[0034] 2 to 5. When the first embodiment is actually used, the seal edge 121 is cut and the pull-out portion 232 of the two ear hooking devices 2 is pulled outward to separate the inner ring portion 23 from the outer ring portion 25 and the fixed portion 21. The inner ring portion 23 simultaneously pulls the connecting portion 22, which pulls out the fixed portion 21 and the two sides of the drip bag 1 together, opening up the space in the receiving chamber 11, and the drip bag 1 is hung on the cup brim 31 of the cup 3 through the ear hooking devices 2. The hanging method can be changed according to different needs.

[0035] (1) As shown in Fig. 2 to Fig. 6, the ear hooking device 2 is hung upright, and the cup rim 31 is hooked at the position of each inner engagement groove 24. The first convex end 221 and the second convex end 231 are effectively clamped on the cup rim 31, and the drip bag 1 faces upward in correspondence with the water inlet 12 above the fixing part 21. The raw material (coffee powder) to be extracted is poured into the accommodation chamber 11 from the water inlet 12 and extracted. With this hanging method, the coffee is filtered out through the side line of the bottom of the drip bag 1.

[0036] (2) See Figures 2, 5, and 7. The ear hooking device 2 is hung diagonally, one of the tearing edges 13 is cut, and the first outer engagement groove 26 and the third protruding end 261 are not bonded to the drip bag 1. When the inner ring portion 23 is pulled open, the first outer engagement groove 26 and the third protruding end 261 are naturally exposed when the two sides of the drip bag 1 are pulled out together, and the cup rim 31 is easily hooked into one of the inner engagement grooves 24 and into the first outer engagement groove 26 located diagonally from the inner engagement groove 24. The first convex end 221, the second convex end 231 and the third convex end 261 are effectively clamped on the cup rim 31, and the water inlet 12 and the cut edge 13 face diagonally upward and communicate to form a large opening. Therefore, the raw material to be extracted (coffee powder) is poured into the storage chamber 11 through the opening connected to the water inlet 12 and the cut edge 13, and extracted. With this hanging method, the coffee passes through the tip where the two sides of the bottom of the drip bag 1 intersect and is filtered out.

[0037] 8 and 9, the second embodiment of the ear hooking device is different from the first embodiment in that the first outer engagement groove 26 is formed so that both sides of the outer ring portion 25 face inward. The third protruding end 261 is located within the first outer engagement groove 26, and the first outer engagement groove 26 and the third protruding end 261 are designed to be conical in terms of contour design, and the remaining structural features are the same as those of the first embodiment, so they will not be repeated here.

[0038] 8 and 9, when the second embodiment is actually used, the ear hooking device 2 is normally hung in the same manner as in the first embodiment, and therefore will not be described again here. The ear hooking device 2 is hung diagonally, one of the cut edges 13 is cut, the cup rim 31 is hooked into one of the inner engagement grooves 24, the third protruding end 261 in the first outer engagement groove 26 facing the inner engagement groove 24 is pulled apart, and the pulled-out third protruding end 261 is hooked together with the cup rim 31. The first convex end 221, the second convex end 231, and the third convex end 261 can be effectively clamped on the cup rim 31. The water inlet 12 and the cut edge 13 face diagonally upward and communicate to form a large opening, so that the raw material to be extracted (coffee powder) is poured into the storage chamber 11 from the opening communicating with the water inlet 12 and the cut edge 13, and the coffee is filtered out by passing it through the tip where the two sides of the bottom of the drip bag 1 intersect with each other in this hanging method.

[0039] The third embodiment of the ear hooking device, as shown in Figures 10 to 12, differs from the first embodiment in that outwardly facing flaps 27 are formed near the inner engagement grooves 24 on both sides of the inner ring portion 23. A second outer engagement groove 28 is formed on the inner edge of the flap 27. In terms of contour design, the second outer engagement groove 28 is designed to be conical.

[0040] In terms of the specific positional arrangement, the two internal engagement grooves 24 and the two second external engagement grooves 28 are respectively close to the water inlet 12, and the two first external engagement grooves 26 are far from the water inlet 12. The two internal engagement grooves 24 and the two first external engagement grooves 26 are arranged corresponding to each other vertically, or the two second external engagement grooves 28 and the two first external engagement grooves 26 are arranged corresponding to each other vertically, so that the internal engagement grooves 24 or the second external engagement grooves 28 can be selectively used. The remaining structural features are the same as those of the first embodiment, and will not be repeated here.

[0041] The third embodiment has a second outer engagement groove 28 that can be used in combination with the inner engagement groove 24 or the first outer engagement groove 26. Since the two second outer engagement grooves 28 are located outside the two inner engagement grooves 24, in use, the relatively outer second outer engagement groove 28 is adapted to engage with a larger cup 3, and the relatively inner inner engagement groove 24 is adapted to engage with a smaller cup 3.

[0042] As shown in Figures 10 to 12, when the third embodiment is actually used, the ear hooking device 2 is properly hooked in the same manner as in the first embodiment, and therefore will not be described again here. When the diameter of the cup 3 is large, one of the cut edges 13 is cut to pull out the flap 27, and the cup rim 31 is hooked into one of the inner engagement grooves 24 and into the second outer engagement groove 28 located diagonally opposite the inner engagement groove 24. The flap 27 and the third protruding end 261 can be effectively clamped on the cup rim 31. The water inlet 12 and the cut cut edge 13 face obliquely upward, and communicate to form a large opening.

[0043] When the diameter of the cup 3 is small, one of the cut edges 13 is cut to fit the cup rim 31 into one of the inner engagement grooves 24 and into the first outer engagement groove 26 located diagonally opposite the inner engagement groove 24. The first convex end 221, the second convex end 231, and the third convex end 261 can be effectively clamped on the cup rim 31. The water inlet 12 and the cut cut edges 13 face diagonally upward and communicate with each other to form a large opening, so that the raw material to be extracted (coffee powder) is poured into the storage chamber 11 through the water inlet 12 and the opening communicating with the cut edges 13, and the coffee is filtered out by passing through the tip where the two side lines of the bottom of the drip bag 1 intersect with each other by this hanging method.

[0044] The fourth embodiment of the ear hooking device is different from the first embodiment in that, as shown in Figs. 13 and 14, second outer engagement grooves 28 facing outward are formed at the positions near each inner engagement groove 24 on both sides of the outer ring portion 25. A fourth convex end 281 is adjacent to the second outer engagement groove 28. The outer ring portion 25 is fixed (bonded) to the two sides of the drip bag 1 in the remaining area and the fixing part 21, except for the area around the first outer engagement groove 26, the third convex end 261, the second outer engagement groove 28, and the fourth convex end 281. In terms of design of the outline, the second outer engagement groove 28 is formed in an inclined U-shape, and the inclination direction is inward at the top and outward at the bottom, and the fourth convex end 281 is designed to be conical.

[0045] In terms of the specific positional arrangement, the two internal engagement grooves 24 and the two second external engagement grooves 28 are respectively close to the water inlet 12, and the two first external engagement grooves 26 are far from the water inlet 12. The two internal engagement grooves 24 and the two first external engagement grooves 26 are arranged corresponding to each other vertically, or the two second external engagement grooves 28 and the two first external engagement grooves 26 are arranged corresponding to each other vertically, so that the internal engagement grooves 24 or the second external engagement grooves 28 can be selectively used. The other structural features are the same as those of the first embodiment, and will not be repeated here.

[0046] The fourth embodiment has a second outer engagement groove 28 that can be used in combination with the inner engagement groove 24 or the first outer engagement groove 26. The two second outer engagement grooves 28 are located outside the two inner engagement grooves 24, so that in use, the relatively outer second outer engagement groove 28 is adapted to engage with a larger cup 3, and the relatively inner inner engagement groove 24 is adapted to engage with a smaller cup 3.

[0047] As shown in Figures 13 and 14, when the fourth embodiment is actually used, the proper hanging of the ear hooking device 2 is the same as that of the first embodiment, so a repeated description will not be given here. When the diameter of the cup 3 is large, one of the cut edges 13 is cut to hook the cup rim 31 into one of the inner engagement grooves 24 and into the second outer engagement groove 28 diagonally located from the inner engagement groove 24. The fourth convex end 281 can be effectively clamped on the cup rim 31. The water inlet 12 and the cut cut edge 13 face diagonally upward and communicate to form a large opening.

[0048] When the diameter of the cup 3 is small, one of the cut edges 13 is cut to fit the cup rim 31 into one of the inner engagement grooves 24 and into the first outer engagement groove 26 located diagonally opposite the inner engagement groove 24. The first convex end 221, the second convex end 231, and the third convex end 261 can be effectively clamped on the cup rim 31. The water inlet 12 and the cut cut edges 13 face diagonally upward and communicate with each other to form a large opening, so that the raw material to be extracted (coffee powder) is poured into the storage chamber 11 through the water inlet 12 and the opening communicating with the cut edges 13, and the coffee is filtered out by passing through the tip where the two side lines of the bottom of the drip bag 1 intersect with each other by this hanging method.

[0049] As shown in FIGS. 1 to 14, the advantages of the present invention are as follows. (1) Different flavors can be created because the coffee is filtered through different routes. Each ear-hooking device 2 can change the route through which the coffee is filtered from the drip bag 1 through different hanging methods. Therefore, the method of filtering the coffee can be freely selected, providing a wide range of options for use. (2) For diagonal hanging, the inner engagement groove 24 or the second outer engagement groove 28 in combination with the inner engagement groove 24 can be selectively used, which is convenient for combining with cups 3 having different opening sizes, thereby providing a wide range of options for use. (3) The inner engagement groove 24, the first outer engagement groove 26 and the second outer engagement groove 28 have the first convex end 221, the second convex end 231, the third convex end 261 and the fourth convex end 281, respectively, which assist in hooking onto the cup rim 31, thereby providing a favorable hooking effect.

[0050] Of course, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that a person skilled in the art can obtain based on the embodiments of the present invention without creative efforts are included in the protection scope of the present invention.
