Description
- This application is a divisional application of U.S. patent application Ser. No. 16/247,223, entitled Self Contained Cold Brew Beverage Container, filed Jan. 14, 2019 which claims priority to U.S. Provisional Application No. 62/625,436, filed on Feb. 2, 2018. The disclosure of each of the above references is incorporated herein by reference in its entirety.
- Infused beverages, such as coffee and tea, have long been consumed. While infused hot beverages are very common, the demand for infused cold beverages, especially for cold brew coffee, has been increasing in the recent years.
- Coffee has been conventionally brewed using hot or boiling water. One drawback of hot brewed coffee is that the taste can sometimes be acidic and harsh.
- Coffee can also be brewed using cold water. Cold brewing provides a rich liquid coffee that can be smoother and less bitter than that produced by traditional high temperature extraction methods because the latter can leach bitter components into the coffee, and the resulting liquid coffee is of a significantly higher pH. A demand has arisen for cold brewed coffee due to the improved taste, and cold coffee brewing is a growing segment of the coffee industry.
- Generally, the cold brewing process involves steeping a mixture of coffee grounds and water for about 8-24 hours and then filtering the mixture to obtain either the extract or the coffee itself based on the proportion of water. This process requires a consumer to handle coffee beans and/or coffee grounds, which is messy and undesirable. For example, in some cases, consumers are required to measure dry coffee grounds (or coffee beans) during the initial steps of the cold brew process. Then, once the cold brew process is complete, consumers are required to dispose of loose, soaked coffee grounds (or coffee beans).
- Another shortcoming of existing cold brew beverage systems is that they are not portable. Brewing cold pressed coffee either requires the use of complex machines or, alternatively, involves a messy process of placing coffee grinds in a pitcher of water in the refrigerator for up to 18 hours, then pouring the mix through a filter before drinking.
- In certain aspects, cold brew beverage products are provided comprising an infusion bag; infusible material disposed within the infusion bag; a receptacle comprising at least one breakable wall, the receptacle containing water; and an outer container, wherein the infusion bag and the receptacle are each disposed within the container.

-
FIGS. 1-2 show a coldbrew beverage product 7 including: aninfusion bag 1;infusible material 2 disposed within theinfusion bag 1; a receptacle 3 including at least onebreakable wall 4, the receptacle 3 containingwater 5; and anouter container 6, wherein theinfusion bag 1 and the receptacle 3 are each disposed within theouter container 6. - In some embodiments, the
breakable wall 4 of the receptacle 3 is formed by a material having a rupture point lower than that of theouter container 6, wherein upon external compression of theouter container 6, thebreakable wall 4 is at least partially ruptured, thereby allowing thewater 5 to flow from the receptacle 3 into theouter container 6 and come into contact with theinfusion bag 1. - In some embodiments, the
infusion bag 1 may be comprised of any non-toxic porous material which can contain the infusible substance and withstand the temperature of the liquid used for preparing the beverage. In some embodiments, the material used to form theinfusion bag 1 is any suitable material, including, but not limited to, paper, plastic or cloth. In some embodiments, theinfusion bag 1 of is made of porous paper. However, it is to be understood thatinfusion bag 1 is not limited to the above-described materials. - In some embodiments, the
infusible material 2 is comprised of any substance suitable for preparing a beverage including, but not limited to, ground coffee, tea leaves, juice extract, etc. The particular grind size of the infusible material 2 (e.g., course, medium, fine, etc.) may depend on the type of material itself, the user's preferences, etc. - In accordance with some aspects, the receptacle 3 in which water is stored is in the form of a water-tight bag. The bag may be made from one or more materials that may be broken open when the user applies force to the product. In some embodiments, the bag may be made from relatively flexible sheet material. For example, in certain embodiments, the bag is comprised of plastic. Preferably, the plastic is free of leachable chemicals such as, e.g., bisphenol-A (BPA). In some embodiments, the material is formed of a heat-sealable plastic. Additionally, in accordance with some aspects, the material has a thickness ranging from about 0.25 mil to about 1.5 mil. However, it is to be understood that the material may be thinner or thicker than the range described above. Furthermore, the material forming receptacle 3 is not limited to plastic and may be any appropriate water-tight material such as, e.g., foil. In order to accommodate for potential atmospheric pressure changes during transport (including high-altitude transport), the receptacle 3 may be flexed and/or compressed before sealing.
- In one specific example,
infusion bag 1 is filled with 1.7 oz. of medium grind, Extra Dark Roast coffee, while receptacle 3 is filled with 20 oz. of water. In additional and/or alternative embodiments, lower ratios of coffee-to-water may be used to maintain similar flavor and character of the final product. These ratios may be dependent upon user preferences and/or characteristics of specific coffee beans and grind levels. - In some aspects of the disclosure, the
outer container 6 is configured in the form of a bag. In some embodiments, the bag may be formed of multiple sheets of flexible material such as, e.g., plastic, polyester, nylon, polypropylene, aluminum foil, polyethylene, etc. The bag may be configured to be vacuum sealable and/or heat sealable at one or more edges. In some embodiments, the flexible material forming theouter container 6 has a thickness of about 3 mil. In some embodiments, the material may be formed of a plastic that is BPA-free. - In some embodiments, the
outer container 6 may include anotch 8. Thenotch 8 may facilitate tearing of an edge of theouter container 6 by the user. Additionally, while not shown inFIGS. 1-2 , the edge ofouter container 6adjacent notch 8 may include serrations to further facilitate the tearing of theouter container 6. Additionally and/or alternatively, the edge of theouter container 6adjacent notch 8 may include a sealing feature to allow for selective opening and closing of theouter container 6. - Referring now to
FIG. 3 , in accordance with some aspects of the disclosure, amethod 10 is provided for cold brewing a beverage. The method including the steps of providing an outer container (step 12), providing an infusion bag having infusible material stored therein (step 14), and providing a receptacle having water stored therein (step 16). Next, atstep 18, the infusion bag and the receptacle containing water are placed within the outer container, and the outer container is then sealed (step 20). The method further includes the step of exerting sufficient external force on the outer container to rupture a wall of the receptacle disposed within the outer container (step 22), forming an opening in the receptacle to allow the water to flow into the outer container such that the water to comes in contact with the infusion bag (step 24), and incubating the outer container at a temperature and for a period of time sufficient to allow the infusible material to steep in the water to produce a beverage (step 26). - Referring again to
FIGS. 1-2 , to prepare a cold brew beverage, the user may apply external force to the one or more sides ofouter container 6 at a level sufficient to result in the rupture of the receptacle 3 containing thewater 5. While the user applies force sufficient to rupture one or more walls of receptacle 3, the force is not so great as to open or ruptureouter container 6. For example, in accordance with one embodiment, the user may apply between 5 and 10 lbs. of pressure on one or more sides ofouter container 6 in order to rupture receptacle 3 housed therein. Once ruptured, thewater 5 flows out of the internal water receptacle 3 and remains inside of theouter container 6 such that thewater 5 enters into contact with theinfusion bag 1. - While receptacle 3 is described above as rupturing simply due to pressure exerted by the user thereon, it is to be understood that other methods of rupturing or otherwise emptying receptacle 3 are also possible. For example, in some embodiments, one or more inner surfaces of
outer container 6 may include one or more piercing members, with the one or more piercing members capable of penetrating the receptacle 3 when theouter container 6 is manipulated or squeezed in a certain way. In accordance with other embodiments, the receptacle 3 may include one or more valves or seals which allow for the expulsion ofwater 5 from the valves or seals after a certain amount of pressure is applied toouter container 6 and receptacle 3. - As described above, in some embodiments, the
infusion bag 1 contains coffee or another infusible material, including but not limited to, tea leaves or juice extract. In accordance with some aspects, theouter container 6 may be squeezed by the user such that thewater 5 is forced from the receptacle 3 into the interior of theouter container 6, thereby assisting in bringing thewater 5 in contact with theinfusion bag 1. Optionally, theouter container 6 may be agitated for a brief time by, e.g., manual shaking. Such agitation may assist in brewing the beverage. - Furthermore, as described above,
outer container 6 may be vacuum sealed afterreceptacle 6 andinfusion bag 1 are placed therein, but prior to the actual brewing operation. Accordingly, the interior ofouter container 6, includinginfusion bag 1 and theinfusible material 2 stored therein, is under vacuum pressure. Thus, when receptacle 3 is ruptured according to the procedure described above,water 5 is rapidly drawn intoinfusion bag 1 and absorbed by theinfusible material 2, thereby expediting the brewing operation. For example, whereas prior art cold brew methods have required the infusible material to steep for many hours in order to obtain optimal flavor and consistency of the beverage, the present method, utilizing both infusible material and water under vacuum, allows for brewing in as little as, e.g., 12 to 20 minutes. Thus, not only does coldbrew beverage product 7 provide for self-contained brewing, but it also allows for expedited brewing as compared to conventional cold brew methods. - In order to produce an optimally-brewed cold brew beverage, the
product 7 may be allowed to incubate at low temperatures for a desired amount of time, dependent upon the user's preferences. For example, in some embodiments, the time period for incubation ranges from about 12 minutes to about 12 hours at conventional refrigerator temperatures (e.g., 32°-40° F.). However, it is to be understood that shorter or longer incubation periods and/or higher or lower incubation temperatures are possible. - After brewing and incubation are complete, an opening may be made in the
outer container 6 to enable consumption of the beverage. As described above, in some embodiments, theouter container 6 is a bag that may be opened by any suitable means such as, e.g., cutting, manual tearing, and the like. In some embodiments, a user may tear the outer container bag at anotch 8 provided in the bag. Additionally and/or alternatively, while not shown,outer container 6 may be configured to include a spout or other opening formed thereon to allow for access to the brewed beverage. In accordance with some aspects, the beverage may poured into a suitable vessel for drinking, such as a cup or glass. Optionally, in accordance with other aspects, theouter container 6 may be configured such that the user may drink the beverage directly from theouter container 6 after the brewing operation is complete. For example, a spout and/or straw opening may be provided inouter container 6. - Once the brewing and incubation are complete, the beverage is ready to drink immediately. The outer container 6 (and all contents still retained therein, including the water receptacle 3 and the infusion bag 1) may be discarded without the mess or cleanup required for traditional brewing methods. The grounds and bags can be placed in a trash or recycling container.
- Next, referring to
FIG. 4 , in another aspect of the present disclosure, amethod 30 is provided for making a cold brew beverage product. Themethod 30 may include the steps of: - a) folding a piece of porous material to form a bag (step 32), the bag comprising a first sidewall of porous material, a second sidewall of porous material overlaying the first sidewall, a first side edge, an opposite second side edge, a bottom edge extending between the first and second side edges to provide an interior volume, and a top edge;
- b) sealing the first and second side edges to form the bag (step 34);
- c) placing infusible material in the infusion bag (step 36);
- d) sealing the top edge to form an infusion bag (step 38);
- e) providing a first and second sheet of water-impermeable material (step 40);
- f) joining the first and second sheets at the peripheries thereof to form a receptacle (step 42), the receptacle comprising a first sidewall of water-impermeable material, a second sidewall of water-impermeable material overlaying the first sidewall, a first side edge, an opposite second side edge, a bottom edge extending between the first and second side edges to provide an interior volume, and a top edge containing an opening;
- g) introducing water into the receptacle through the opening (step 44);
- h) sealing the opening to form a water-tight receptacle (step 46);
- i) placing the infusion bag and the water receptacle between a first and a second sheet of an outer material having a higher rupture point than the material from which the water receptacle is formed (step 48); and
- j) joining the first and second sheets of the outer material at the peripheries thereof to form an outer container, wherein the infusion bag and water receptacle are disposed within the outer container (step 50).
- In some embodiments, the porous material may be formed of a paper material. In some embodiments, the porous material used to form infusion bags may be sealed by any known sealing process, including, but not limited to, heat sealing.
- In some embodiments, the water may be purified prior to being introduced into the receptacle. In such embodiments, the water may be purified by any suitable method. For example, the water may be purified by a reverse osmosis procedure. As purified water is substantially free from impurities, it will absorb into the infusible material more quickly than unpurified water, thereby further expediting the brewing process. Additionally, because of its improved absorption characteristics, the use of purified water may also allow for a reduction in the amount of infusible material needed to obtain a beverage having desired flavor characteristics. For example, instead of utilizing 1.7 oz. of infusible material (e.g., ground coffee) to 20 oz. of water as described above, the use of purified water may allow for a ratio of, e.g., 1.5 oz. of infusible material to 20 oz. of water. While minimal on a per-beverage basis, such potential savings in infusible material becomes drastic when large volumes of cold brew beverage products are produced in an industrialized setting.
- In some embodiments, the receptacle 3 may be a water-tight bag. The bag may be formed with a first sidewall and a second sidewall of flexible plastic material. The first and second sidewalls may be overlaid and joined to each other along a first side edge, a second side edge, and a closed bottom edge extending between the first and second side edges to delineate the interior volume. To provide the opening for accessing the interior volume, the top edges of the respective first and second sidewalls, located opposite the closed bottom edge, may remain un-joined.
- The water-impermeable material used to make the water receptacle 3 may be of any suitable material. In embodiments, the material may be a relatively flexible, material such as e.g., plastic, polyester, nylon, polypropylene, aluminum foil, polyethylene, etc. In some embodiments, this material may have a thickness of about 0.25 mil to about 1.5 mil.
- In embodiments, air may be expelled from the receptacle 3 prior to sealing the receptacle.
- In embodiments, the water-impermeable material used to make the water receptacle 3 may be sealed by any known sealing process, including, but not limited to, heat sealing.
- The
outer container 6 may be formed from any suitable material. In embodiments, the material is water-impermeable and has a higher rupture point than the material from which the water receptacle 3 is formed. In embodiments, the material may be a relatively flexible material such as e.g., plastic, polyester, nylon, polypropylene, aluminum foil, polyethylene, etc. In one embodiment, the material used to form theouter container 6 has a thickness of, e.g., about 3 mil. - In some embodiments, the material used to form the
outer container 6 may be sealed by any known sealing process, including, but not limited to, heat sealing. Additionally, in some embodiments, theouter container 6 is vacuum-sealed. - The definitions of the words or elements of the following claims are, therefore, defined in this specification to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements in the claims below or that a single element may be substituted for two or more elements in a claim. Although elements may be described above as acting in certain combinations and even initially claimed as such, it is to be expressly understood that one or more elements from a claimed combination can in some cases be excised from the combination and that the claimed combination may be directed to a subcombination or variation of a subcombination.
