Beverage brewing device [Cross-Reference to Related Applications]

The present application claims the benefit of the U.S. Provisional Patent Application Serial No. 60/926,393, filed on Apr. 25, 2007, which is incorporated herein by reference.

The present invention relates to disposable hot beverage brewing devices such as coffee, tea and herbal products. More particularly, the present invention relates to disposable containers for hot beverages containing filter paper that collects solids from the container but still allows fluid to pass therethrough. The permeability of the liquid has been designed to pass through the cup hole/cutting zone, which allows the liquid to penetrate into the lower container cup under the user's time limit selection. How many holes or how large the cut area is configured will determine the length of the extraction time (for example, 2 minutes, 3.5 minutes or 5 minutes).

The present invention is ultimately designed to agitate in a pre-packaged 3-in-1 (i.e., coffee, sugar and powdered cream) coffee blend product in a suitable time and space, the coffee blend product being in a single pouch. The time and space for proper agitation is critical for 3-in-1 coffee blend preparation. If it is not agitated, the powdered cream which has been uniformly mixed with sugar and coffee will form a lipid film (a masking effect) when it comes into contact with hot water, so that it is difficult for hot water to permeate into the remaining mixture. The 3-in-1 coffee blend will stick together and form a viscous compound, making the extraction process abnormal. Therefore, it is particularly important to have a brewing device that allows proper agitation for a prepackaged beverage mix having powdered butter as one of its main ingredients.

I know that coffee is consumed in many parts of the world and it is the oldest drink. Therefore, there are a wide variety of devices for brewing coffee. Coffee grounds (impregnation) are traditionally brewed in a coffee maker. Later, because of the ease of use of the EPR coffee machine, people prefer to brew coffee in it. In addition, instant coffee is also chosen by many people due to advances in jet drying technology. These are all suitable ways to taste a cup of coffee, however due to the time limit, mobility and the taste of the brewed coffee during brewing. Each of these methods has its own shortcomings in terms of whether or not the aroma is rich.

A small amount of coffee grounds is repeatedly boiled in the coffee percolator/coffee pot to eject liquid above the slag, which can cause the coffee to have a burnt smell and the possibility of excessive precipitation. In short, it makes the coffee that is finally obtained bitter. Epoxy coffee machines have gained the favor of most families around the world. Despite its name, it is not suitable for portability and mobility and is not suitable for outdoor use. For people like general office workers (people who don’t have their own coffee brewing utensils or who like to drink different coffee groups), accommodation students and remote commuters, there is no advantage in electrospray coffee. At that time. Instant coffee is the quickest way to brew a cup of coffee in other methods as described above. However, the main disadvantage of instant coffee is that it is too expensive to make. In general, 1 kg of instant coffee is equivalent to 2 kg to 2.6 kg of coffee beans. Similarly, most people still believe that instant coffee (treated coffee) has a lower quality of flavoring compared to natural fresh ground coffee. Similarly, although convenient, it comes at the expense of taste and sophistication.

We have developed many brewing devices for tea, coffee and herbal drinks. Such a device (Calagui, Juanito B. (Passaic, NJ), et al., U.S. Patent No. 6,263,781, issued July 24, 2001) is a cup-shaped container with a filter element, the filter element being configured with the cup-shaped container The internal bulge is engaged. This device does separate the insoluble coffee grounds during the brewing process. However, when someone tries to inject hot water into it, the hot water passes and separates very quickly. The device does not allow hot water to remain in proper contact with the coffee ground for a certain period of time. As a result, the coffee beverage is light (coffee term: insufficient precipitation). If the hot water is not brought into contact with the pre-mixed coffee grounds, cream and sugar will make it impossible to stir the beverage even for a short period of time. Therefore, the prepackaged 3-in-1 coffee blend is not suitable for brewing using this device. On the other hand, in order to obtain a better-tasting coffee drink, only when pouring hot water into the device, we need to pour a small amount of hot water each time and repeat it, so it must have sufficient patience. In the process of being able to last for more than 10 minutes, it is not the ideal way to get a cup of coffee drink by repeatedly pouring a small amount of hot water near the brewing device. In addition, in the filter element The device does prevent the coffee grounds from being drunk when the pieces are wrinkled and the coffee grounds are added to the cup-shaped container before pouring it. However, it also destroys the taste and aroma of the coffee. This is because coffee grounds are still in contact with hot water and will continue to be precipitated despite separation. The time required for the correct precipitation process is not more than the recommended time (4 to 8 minutes depending on the roughness of the coffee grounds). If the time taken is too long or more than the recommended time, more unfavorable ingredients that cause the coffee to taste bitter and smell astringent and destroy the coffee aroma will also be precipitated.

The release of the heat of the hot steam accumulated during the brewing process is a critical step. This is especially important when the container is a retractable assembly that is preferably placed over the container cup. This assembly can be firmly fixed to the brewing cup, but on the other hand, it does not consider the release passage of hot steam generated when pouring hot water close to boiling. The accumulated heat will accumulate and form a resistance, resulting in an increase in heat, so that the dripping process caused by gravity is slowed or hindered. When the situation is slight, it slows down the dropping process, but in extreme cases it can even stop the dropping process completely, depending on the temperature of the hot water used and the material used in the filtration. The patent is Hayes, Susan M. (New York, NY), and one of the patents No. 4,520,716 is one such device that does not have a hot vapor release vent for the sitting-on beverage brewing device in the prior art.

Many brewing devices cannot be used for pre-mixed or pre-packaged beverages, such as 3-in-1 coffee mixes or 3-in-1 tea mixes. This is because many of these brewing devices do not take into account the critical importance of agitation during the preparation of this product with powdered cream as one of its main ingredients. Using a filter paper bag or a method of brewing a bag, such as U.S. Patent No. 5,478,581 (Christie, Hugh P. (Hyde Park 5061, AU); Wallace, Allan K. (Hindmarsh 5007, AU)) An example of how difficult, if not impossible, complete dilution and precipitation of a coffee mix or tea mix (which may be included in the capsule process). This results in a masking effect due to the grease from the powdered cream, thereby preventing further penetration of hot water into the remaining mixture. Products belonging to this category can be classified as closed brewing systems. In this system, not allowed The user implements any type of change to the product. For the user, this system is not flexible, for example, it neither increases nor reduces the amount of coffee grounds added to the bag/bag.

U.S. Patent No. 4,619,830 (Napier, Edward D. Scarborough, Ontario, CA) discloses a brewing device that employs an open brewing system that provides more flexibility to the user, such as increasing or decreasing the amount of coffee added to the beverage. The amount of slag, sugar or powdered cream. However, the support bar/rod in the middle of the top opening allows the user to feel uncomfortable or difficult to perform a proper agitation exercise during the preparation of the beverage.

Each of the prior art disclosed has exhibited one or more disadvantages, so it has so far failed to be a mass production product for brewing coffee to go or a widely used method. The present invention improves upon other deficiencies inherent in the prior art and provides the public with an inexpensive, novel, single-use, adaptable, mobile, easy to use, and more accurate brewing time based on coffee experts' recommended brewing time. Device.

Coffee, tea and herbal products are very complex products. Each product requires a specific special treatment to get the best benefit. Since all of these products require the use of hot water to precipitate the complex components contained therein, the use of a suitable brewing device is particularly critical. The present invention is designed to provide a brewing appliance with precise brewing time.

A large number of coffee lovers are accustomed to adding sweets and cream to their coffee drinks. For these drinkers, they hope not to add sugar and cream separately. For example, such persons would like to include a "real" pre-packaged mixture of ground coffee, sweeteners and cream. Unfortunately, previous attempts at products containing a mixture of coffee, cream and sugar granules within the filter element were disappointing.

Accordingly, it would be desirable to invent a compact, inexpensive, unitary, and moveable device having a filter element for containing the prepackaged beverage mix for preparing an infused beverage such as coffee, tea, and the like. This prepackaged mixture will be placed in the brewing cup with hot water for a sufficient time to brew the coffee. Measuring the foregoing The needs and necessity of each component are avoided.

The invention has four main objectives. The first goal is to provide the public with an appropriate and accurate device based on the written recommendations of the Specialty Coffee Association of America, which is intended to be used to prepare a cup of delicious coffee beverage with coffee grounds and hot water. Long time." The second goal is to provide an open brewing device that allows the public to have more flexibility in choosing which ingredients to brew. A third objective is to provide a brewing device having a hot steam release vent and which can also be placed tightly on the top of a regular coffee handle cup or disposable cup. The fourth object is to provide a brewing device which can be easily agitated when brewing a 3-in-1 prepackaged powdered beverage which is one of its main components.

A cup-shaped container comprises a liquid permeable disposable brewing filter having an open top and partially closed bottom support. It consists of a number of perforated coated papers at the bottom support of the cup, or polyethylene, or polystyrene, or biodegradable materials (including but not limited to, such as modified organic fibers and/or unmodified organic fibers, And/or pulp, and/or starch, and/or any composition thereof. The number of holes or the number of cutting zones is a time control mechanism that plays a key role in controlling the flow of liquid to the bottom of the container cup or mug in the present invention. The area of each hole is 28.26 square millimeters. Although this size is ideal for generating droplets of raindrop size, the size of the hole/cutting region can vary. Preferably, the perforation of the present invention accounts for about 16.9% (diameter (? 15 mm) to 9.1% (diameter of diameter) of the bottom of the brewing cup (area 4183.3 mm ² ). 11 mm); more preferably, the area percentage is about 7.5% (□10 mm) to 3.7% (?mm); more preferably about 2.7% (?mm) to 0.68% (□3 mm).

Moreover, in an alternative, the shape of the open area of the bottom of the brewing appliance can be varied to any type of shape. The change of the bottom of the brewing device is expected to enhance its aesthetic appearance, including but not limited to triangle, rectangle, ellipse, diamond, petal, star, circle, heart, crescent, fan, nine sides Shape, octagon, pentagon, decagon, and hexagon, or any combination of these shapes.

The bottom support of the filter cup is designed to have four concave shapes that are curved inwardly, in this embodiment, for releasing the vapor that collects during the brewing process. The equiangular angle allows the hot steam accumulated on the container cup to escape as it is disposed on a container cup with a handle. During the brewing process, the vent is important to create a non-resistive environment for the liquid to flow from the top to the bottom. The number of petal angles can be maximized or minimized depending on the desired output of the heat vapor release rate (HSR).

When placed on a regular container cup or the like cup having a top inner opening diameter of 7.2 cm to 7.5 cm in a telescopic manner, it can be tightly mounted to the cup without any fixing means. For a handle cup having an inner top opening diameter of 7.6 cm to 8 cm, an attachable thin polystyrene sheet is used on the outer bottom of the cup placed on the bottom. Depending on the width of the top opening of the container cup, the number of thin polystyrene sheets used may be one or more sheets. In addition, for a larger diameter handle cup, such as a cappuccino mug having a diameter greater than 8 cm, it uses a fully mounted mounting device that is circular and has three serrations. Support legs. All of the above designs are suitable for securely securing the cup container to the container cup and providing good maneuverability during the brewing process.

The filter paper or other porous material is attached to the bottom support of the filter cup via heat sealing or food grade starch. A heat seal of about 5 mm wide was applied around the outer edge of the filter paper to the bottom support of the filter cup. The 5 mm heat seal width provides some flexibility in flexibility to create a better pressure point during the drop down process. If the user can easily peel off the filter paper, in order to preserve the natural resources and protect the environment, it is possible to reuse the cup assembly and discard one of the used filter papers instead of the specific embodiment. With the 5mm heat seal width design, the user can more easily peel off the used filter paper since it is only attached to a small area of the bottom support of the filter cup. Since the commercial filter paper contains polyethylene on its side, heat sealing can be performed. Upon heating, the polyethylene material melts and becomes part of the cup assembly.

The "Porous Configuration/Cutting Configuration" and "A Single Cutting Configuration" have been compared in Table 1 for the cup base area: r = 36.5 mm 3.14 x 36.5 mm x 36.5 mm = 4183.265 mm ² hole area: r = 3 mm 3.14 x 3 mm x 3mm = 28.26 mm ²

Test steps:

Two cups of precise size were used in this test. One of the cups has a hole at the bottom and the other cup has a closed bottom. The perforated cup was used to test the speed at which it reached the 120 ml mark on the test container, while the other cup was used as a metering standard for 170 ml of water. To prepare the filter paper for the test process, the cup has been pre-wetted by hot water. The time taken when the water level reached 120 ml on the measuring container was recorded with a stopwatch.

As can be seen from Table 1, the results of the brewing vessel having a porous configuration are more stable than those of other configured brewing vessels. And even with the same ratio, the porous configuration proved to be faster than a single cut configuration. This is because each cutting zone has a pressure point at the center of the orifice. When the filter paper is wetted by the hot water and subjected to gravity, the filter paper will elongate and bend to a certain extent during the brewing process to form a pressure point. According to the test results, the more the number of outlets, the faster the liquid is allowed to pass through the filter paper into the container cup/handle cup. The test also showed a single cutting configuration, for example, a ratio of 13.51%, which reached a rate of 120 ml mark water level (8 seconds and 53 milliseconds) than the same ratio of 20 multi-cut configurations (3 seconds and 85) Milliseconds) slow. This one cutting configuration has also proven to be less stable and reliable as a time control mechanism.

In general, the present invention provides a disposable brewing device made of inexpensive materials such as coated paperboard or polystyrene or polyethylene and filter paper. In an alternative, the filter paper can also be used to conserve natural resources only when the filter paper is the only part that is discarded after use of the entire assembly.

As seen in Figures 1 and 2, a droplet type coffee brewing device, or a herbal brewing device, or a tea brewing device includes a filter cup 10 which is made of the following material group, the material group including However, it is not limited to polystyrene compounds, plastics, organic and/or non-organic biodegradable polymers, and/or modified organic fibers, and/or unmodified organic fibers, and/or pulp, and/or starch, And/or coated cardboard, and/or combinations thereof. With regard to the filter cup 10, it can be seen that it has a partially closed bottom support 110, the bottom The outer support 110 has an outer diameter of about 7.3 cm and its outer side wall 105 tapers outwardly toward the top open mouth 103. The top open mouth 103 has an outer diameter of about 8.5 cm. The filter cup 10 is made of a water permeable material or a porous material, preferably made of a commercial filter paper 121 having sufficient strength in the case of being wetted, and one side of the filter cup 10 is coated with polyethylene and It is quite cheap, so it can be discarded after one use. The filter paper 121 is attached to the bottom support 110 of the filter cup 10 via a heat seal, or food grade starch, or an ultrasonic sealing system or an ultrasonic sealing system. The filter cup 10 is designed to have a plurality of perforations 108 thereon for use as a time control structure on its bottom support 110. These perforations 108 are important for brewing different types of ingredients because each component is properly and correctly deposited. The time limit seems different. The area of the heat seal along the annular edge of the filter paper has a width of about 5 mm.

Each of the perforations 108 of the present invention is 28.26 mm ² . Although the size of the perforations 108 can vary, this size is ideal for producing natural water droplet sizes. The water collects at the pressure point 625 and is converted to a maximum size before it begins to drip in the form of water droplets, ranging from 3 mm to 8 mm in diameter. The size of the water droplet that reaches its maximum size does not change to a larger size as the perforation 108 changes. Therefore, in this type of filter brewing device, it is the most effective way to control the dripping process within the maximum range of water droplet size. This invention is distinct from other key points of the invention having a larger perforated outlet configuration or a too small perforated outlet configuration. The perforations 108 are configured such that each of the perforations 108 are spaced apart from each other by at least 3 mm. To maintain a standard drop velocity, this is important to create separate droplets 630 (Fig. 6) that are closely spaced from each other without interfering with each other. Subject to gravity, the liquid descends from the upper portion to the lower portion, and all of the perforations 108 will achieve substantially the same force and release the water droplets at approximately the same rate. In other words, the perforations 108 are subjected to substantially the same amount of energy released by gravity, or uniformly distributed to each of the perforations 108 by gravity. The main benefit of this design is that it produces water droplets that are independent of each other and of uniform size. As can be seen from the following tests, the more standard the drop rate is, the more accurate it is as a time control mechanism. Similarly, the more gravity is released, the faster it will adapt to faster brewing.

As is clear from Fig. 6 and Fig. 7, when hot water is poured onto the filter cup 10, a pressure point 625 is formed on each opening/cutting region, and gravity acts to cause the hot water to flow downward, which naturally forms an arc. The lowest point of the arc is the pressure point 625 on the filter paper 121 that we refer to. There are a plurality of pressure points in Figure 6, and the specific embodiment of Figure 7 has only one pressure point. Despite the larger cut size, the pressure point 625 of Figure 7 causes the drop 630 to be unstable and unpredictable. On the other hand, the pressure point produced by the multi-perforation 108 configuration in Figure 6 is more predictable, as described in Table 1, which proves to be more stable.

A heat seal region 109 (Figs. 3 and 4) of about 5 mm width is applied to the outer periphery of the filter paper 121 to the bottom support 110. The 5 mm heat seal width provides some flexibility to form a better pressure point 625 during the drop down process (Fig. 8). Since the commercial filter paper 121 contains polyethylene on one side thereof, heat sealing is possible. When heated, the PE material melts and becomes part of the filter cup 10 assembly.

Furthermore, to ensure that liquid flows from the upper filter cup 10 to the bottom of the container cup 11 without resistance, the present invention provides a hot steam escape path. The filter cup 10 provides four concave vents 201 (Figs. 1 and 5a) on the lower portion of its outer side wall 105. In a stack of assembled brewing devices, the accumulation of hot steam has become a problem. The hot steam accumulated in the lower container cup 11 has become the main culprit in the slowing of the precipitation process. Throughout the test, we have used a fully assembled nesting assembly with no gaps between one or two cups. The accumulated hot steam accumulates to form a large force acting upwards, thus delaying the dropping process. This test shows that gravity does not work as expected in this situation. Therefore, releasing the accumulated hot steam enables the liquid to flow from top to bottom in a non-resistive manner. The present invention has four inwardly curved inner concave vents 201 that are up to about 6 mm deep, about 1 cm wide, and tapered upwardly up to 2.5 cm. Therefore, the main function of the vent 201 is to avoid accumulation of pressure which may increase the brewing time during the brewing process of the container cup 11. When the vents 201 are disposed on a container cup 11, they dissipate the hot steam accumulated on the container cup 11 (Fig. 1). Expected to lose according to hot steam release rate (HSR) The value of the petal can be maximized or minimized. When viewed from the bottom up (Fig. 5a), the filter cup 10 looks like a flower with four petals.

The filter cup 10 uses the filter paper 121 to a minimum compared to any other similar product and is particularly effective compared to a tea bag for brewing a tea beverage. Throughout our brewed tea beverage trials, the specific embodiment of the present invention having a configuration of 6 perforations 108 has a brewing time of about two minutes, which is the same as recommended by most tea bag brewing methods. In comparison, most tea bags require 13,140 mm ² (length 146 mm, width 90 mm) filter paper, while the invention only requires 4183 mm ² (3.14 x 36.5 mm x 36.5 mm) filter paper, and the efficiency of using filter paper is The majority of tea bags are 300%. In addition, for a more efficient and accurate mechanism, it is possible to apply a single hole sealing system. For example, each individual perforation 108 having a full coverage of 5 mm in diameter requires only a circular filter paper having a diameter of 7 mm. With this manufacturing method, we can save up to 75% of the current amount (4183.3mm ² ) of filter paper 121, and the filter paper 121 used is almost 1400% more efficient than most tea bags (13140 mm ² divided by 923 mm) ² ). This is because the requirements of the filter paper 121 can be adjusted according to the number of perforations and the brewing time limit requirements. According to the calculation below, a 6-perforation configuration requires only 922 mm ² filter paper: 7 mm ² filter paper sealed to 6 perforations will be 3.14 x 7 mm x 7 mm = 154 mm ² x 6 (number of perforations 108) = 923 mm ² . Therefore, in order to achieve a specific precipitation requirement, unlike the other brewing methods, the filter cup 10 does not waste any unnecessary filter paper 121 by using a more flexible perforation 108 number configuration.

When the mouth of the container cup 11 whose opening diameter on the inside of the top portion is in the range of 7.2 cm to 7.5 cm is engaged in a nesting manner, the filter cup 10 is tightly mounted on the container cup 11 without any fixing means. In order to closely position the filter cup 10 on the top of the container cup 11 having a diameter of 7.6 cm to 8 cm at the inner top opening thereof, the filter cup 10 uses an attachable thin rectangular polystyrene sheet 610 on the outer bottom portion thereof. (approx. 3 mm (thickness) x 2.5 cm x 2 cm) (Fig. 2). Depending on the width of the top opening of the container cup 11, the number of thin polystyrene sheets 610 used may be one or more. The thin layer polystyrene sheet 610 may be pre-attached to the filter cup 10 during manufacture, or It is provided with a double-sided tape that is attached by the user whenever he wants. The nested engagement of this embodiment is the most practical way to secure the container cup 11, and thus provides a one-of-a-kind disposable coffee or tea brewing appliance for the busy public.

In addition to supporting the filter cup 10 over the container cup 11 having a top opening having a diameter greater than 8 cm, the filter cup 10 uses a fully mounted support ring 233 (Figs. 9 and 10) which is circular There are three serrated support legs 238, each having a length of about 3.5 cm. Each of the serrated support legs 238 is positioned about one third of the circumference of the ring. Each of the serrated support legs 238 has a predetermined serrated portion on the serrated portion 239 of its support leg that is positioned to lock the filter cup 10 to a larger top opening of the container cup 11 during the brewing process on. The material used for the support ring 233 can be a sturdy plastic, paper-based material, wood, bamboo or a composite of various metallic materials. The width 235 of the support ring 233 is about 1 cm, which tapers outwardly and has a top diameter 236 of about 7.5 cm and a bottom diameter 237 of about 7.3 cm.

In an alternate embodiment, the filter cup 10 is constructed of materials such as those listed below, including but not limited to materials such as plastics and/or polymers, wherein after each brew cycle only The filter paper is peeled off and discarded by pulling a peelable half ring 505 (Fig. 3-4), thereby preserving natural resources. When the filter cup 10 is made of polyethylene, and/or polystyrene, or a combination thereof, such as, but not limited to, having good durability, the durability of the present invention can be extended to a higher level of efficiency. By utilizing such materials, since the filter cup 10 can be repeatedly used, the economic value of the filter cup 10 itself becomes extremely insignificant. The only part that is discarded during the entire brewing cycle is filter paper 121 that is easy to recycle. The present invention provides a significant increase in environmental cleaning by recycling only the parts that are critical to the brewing process and allowing the support material to be reused continuously (the filter cup 10). By heat-sealing the filter paper 121 onto the paper, it is easy to make a polystyrene cup or a polyethylene cup. A solder-like simple tool is inexpensive and is considered a general household tool that can be modified to a food grade (stainless steel) heating tip and used to seal filter paper 121 to the bottom 110 of the filter cup 10. another One option would be to use HVS paper or protective material of the same shape and size as used in conventional ironing to prevent conventional solder from directly contacting the filter paper 121. The filter paper is sealed because it contains polyethylene on one side. When heated, the polyethylene melts and attaches to the bottom of the filter cup 10 as part of the filter cup 10. The filter cup 10 can be reused when performing brewing. All that is done is to thoroughly and properly rinse and rinse the filter cup 10. The filter paper is cut into a circular shape with two predetermined peelable half-rings 505 (Figs. 3-4) at each pole, which facilitates the filter paper 121 after the filter cup 10 has been rinsed. The stripping process becomes easy. When the filter cup 10 is wetted, the filter paper 121 is more easily peeled off. After the filter cup 10 is dried, a new filter paper 121 can be sealed to the filter cup 10 at any time, thereby forming another reusable new brewing device.

A standard coated paper filter cup 10, unless perforated, is sealed by a thin layer of polyethylene material to prevent any non-food grade material contained within the paper itself from contaminating the beverage contained within the filter cup 10. Therefore, in an alternative, particularly for the coated paper filter cup 10, there is a process of recoating the perforated inner side wall with a waterproof and heat resistant material such as polyethylene, including but not limited to Any type of food grade wax, resin, organic or synthetic polymer, modified or unmodified sugar based coatable material. Methods of recoating include, but are not limited to, brushing, spraying, and/or dipping.

Another alternative to performing a recoating process on the bottom support 110 after avoiding the perforation 108 is to change the material of the bottom support 110, including but not limited to polystyrene, Biodegradable materials such as modified and/or unmodified organic fibers and/or pulp and/or starch and/or polyethylene. During manufacture, the support 110 of the filter cup 10 made of polystyrene and/or biodegradable material and/or polyethylene is loaded into the paper cup forming machine for combining into a new filter cup 10 combination, the filtration The cup 10 has a coated outer side wall 105 with polyethylene and/or biodegradable material and/or polyethylene bottom support 110. With this combination, the need to apply the perforations 108 can be eliminated because the materials used are food grade. Another benefit is manufacturing The new combined filter cup 10 reduces the need to pierce the perforations 108 during this period. This is because the perforations 108 are made of a material such as polyethylene and/or polystyrene which is formed in a mold having a predetermined number of perforations during formation of the bottom support 110 of the filter cup 10.

Another alternative to making the filter cup 10 perforations 108 very flexible for any type of deposition is to form a maximum number of semi-perforations 107 on the bottom of the bottom support 110 (Fig. 5b). The perforation is formed as a half cut 107 (about one fifth of its total support area) with a small convex portion 107a of a peeling semi-perforation, and one of the peeling semi-perforated small protruding portions 107a is from the filter cup The holder 110 of 10 is convex to allow easy pulling or peeling of the person who prepares a particular desired brewing if necessary. The half cut 107 is configured to have a plurality of small cuts and gaps along the outer edge of the perforation 108, but is not punctured to prevent loosening from the bottom support 110. Although a small amount of leakage may occur from the unpeeled perforations 108, this method allows the user to strip any desired number of perforations 108 to perform its particular brewing requirements.

Alternatively, to save storage space on the retailer's shelf and provide a single packet filter cup 10 + a separate pouch (coffee/tea + sugar + cream), the filter cup 10 can be formed in a folded configuration. The folded shape or structure of the filter cup 10 (as best seen in Figures 5c and 5d) may be formed during manufacture by using a particular forming process, and/or heat treatment, and/or compression molding, or a combination thereof, directly or indirectly. All of the outer side wall 105 of the filter cup 10 or a portion of the outer side wall 105 is affected. The folded shape or configuration of the filter cup 10 allows the filter cup 10 to be shortened or collapsed (Fig. 5d) so that it can be mounted into a disposable bag. When the bag is opened, the person can easily pull the squashed filter cup 10 into the filter cup 10 of the normal height (Fig. 5c) without changing its main function as a filtering device.

In carrying out the operation of the present invention, it is possible that the filter cup 10 has been assembled as described and illustrated and supported on top of the container cup 11. As shown in Figure 1, a pre-mixed pouch contains about 25 grams of ground coffee 612 + sugar + powdered cream that has been opened and poured onto the filter cup 10. When the hot water reaches a suitable temperature, Hot water is then poured into the filter cup 10 and the filter cup 10 is almost filled into the top open mouth 103. The dropping process begins immediately, but there is still enough time to stir the mixture. When the inside of the filter cup 10 is completely filled with hot water, the front and rear stirring motion is required to last for about 30 seconds to 1 minute. Proper agitating motion is critical to eliminating the matte effect of the grease layer produced when in contact with hot water. After the agitation process is carried out, the user only has to wait until the mixed beverage has completely dropped onto the container cup 11. In addition, the filter paper 121 has accumulated all the components which cannot be deposited on the assembly of the filter cup 10. The beverage brewed in the filter cup 10 permeates through the filter paper and is dropped from the other side to the container cup 11.
