The dissolvable paper may be a dissolvable label sold under the trademark DISPERSA by NEENAH.
[0055] Preferably, both dissolvable sheet 112 and dissolvable adhesive 114 are edible. The dissolvable, edible, sheet (paper based or pva based) could be provided in any suitable manner, for example in an individual sheet form or in a roll form, for ease of construction of a dissolvable packet, such as dissolvable packet 100. When the dissolvable, edible, sheet (paper based or pva based) 110 is provided in a sheet form, the size of the sheet 112 may be configured and sized such that the dissolvable, edible, sheet (paper based or pva based) 110 may be folded up and sealed into a suitable shape for a packet, such as an elongated package shape or a rectangular/square package shape. When the dissolvable, edible, sheet (paper based or pva based) 110 is provided in a roll form, the package 100 could be fabricated using a tube-filling machine that creates a fin seal along a longitudinal length of the tube along a length of package 100 having opposing end fin seals that closes ends of package 100.
[0056] The sheet could be fabricated from a paper material and/or polyvinyl alcohol and be dissolvable in a liquid (e.g., water). For example, the sheet could be a dissolvable sheet, such as those disclosed in U.S. Pat. Nos. 8,802,591, 7,514,262, 6,845,982, 6,828,018 and U.S. Patent Publication No. 2014/0010989, all of which are incorporated here by reference. The liquid may preferably be a consumable or edible beverage, such as water or juice. Whatever the liquid, the dissolvable, edible packet comprises a material that is soluble for a liquid that it is designed for, and preferably every element of the packet, from the walls to the adhesives used to the contents of the packet, are all edible for human consumption.
[0057] As stated above, the dissolvable, edible, sheet (paper based or pva based) preferably includes a dissolvable adhesive, such as adhesive 114, used to affix the paper to another dissolvable or dispersible object, or to itself. The adhesive is preferably an edible (food grade) adhesive compliant with regulations (e.g. FDA regulations) for human consumption. The adhesive could be coated on an entire side of sheet 110, such as shown in
[0058] By way of example and not limitation, as shown in
[0059] Consumable material 120 could be any edible material, such as a beverage, vitamins, coffee, protein, oatmeal, rice, additives, tea leaves, flavors, preservatives, medical formulations, and/or moisture absorbent materials. However, package 100 and anything placed within it is preferably an edible, food-grade material ingestible by a human being. Preferably, the pH of the material is close to 7, within 0.5 of a pH level. In embodiments where consumable material 120 comprises a coffee, the coffee could comprise a dissolvable coffee. The consumable material (e.g. coffee, protein) could be provided in a granular form (e.g. less than ¼ inch in diameter) or solid form (e.g., greater than ¼ inch in diameter), and may be dissolvable (majority of solid bonds liquefy), partially dissolvable (minority of solid bonds liquefy), or dispersible (disperse into liquid to increase a distance from one another). All of the consumable material 120 may be provided in a powder, granular, or a solid form of any suitable size.
[0060] An alternative package 300 is shown in
[0061] A logo 308 could be printed on dissolvable, edible, sheet (paper based or pva based) 310, allowing a user to brand the sheet (paper based or pva based) with any suitable information related to the edible material contained within package 300, such as a label indicating the consumable material within, or a logo indicating a brand that provides the consumable material. While dissolvable, edible, sheet (paper based or pva based) 310 and 320 are shown as substantially elliptical or circular, dissolvable, edible, sheet (paper based or pva based) could comprise any suitable shape, for example rectangular, pentagonal, hexagonal, semi-circular, or even irregular (e.g. snake-shaped or shaped like one or more alphanumeric characters). Logo 308 could comprise an ink that dissolves or disperses when placed within a liquid, such as water, coffee, or juice. In some embodiments, logo 308 comprises an edible substance, such as sugar or frosting, that is printed on dissolvable, edible, sheet (paper based or pva based) 310 and does not dissolve or disperse when placed within a liquid, allowing the logo to float on top of a surface of the liquid or sink within the liquid in substantially one piece.
[0062] In some embodiments, logo 308 could be printed by a user of dissolvable, edible, sheet (paper based or pva based) 310, for example by a barista who purchases dissolvable packet 300. In such embodiments, the barista could print the logo onto a dissolvable, edible sheet (paper based or pva based), such as either of sheet (paper based or pva based) 310 or 320, using mechanical tools, such as a frosting dispenser, or could download a 3-D printing file from a database made available to the barista, which could then be fed into a food 3-D printer to print logo or design 308 onto dissolvable, edible, sheet (paper based or pva based) 310. In this way, custom designs could be made that could float on a beverage after dissolvable packet 300 is dissolved within a beverage. In some embodiments a QR code could be printed on a top of a container (not shown) for package 300, which, when scanned by a scanning device, directs a computing device functionally coupled to the scanning device to a database having such custom designs for the package in the container.
[0063] An alternative package 400 is shown in
[0064] An alternative package 500 is shown in
[0065] While package 500 is shown to have two package sections divided by a seal, more or less package sections could be formed in other embodiments. In some embodiments, the package could be shaped in a substantially linear fashion, dividing package sections into segments that can be cut or ripped (e.g. along a perforation line). In such embodiments, each package section could comprise same or different consumable materials, or could comprise repeating different materials (e.g. dried coffee then powdered milk then dried coffee then powdered milk).
[0066] Yet another alternative package 600 is shown in
[0067] Any of dissolvable packages 100, 300, 400, 500, or 600 could be filled with consumable material in any suitable manner, for example with a tube-filling machine, a package-filling machine, or by hand. In preferred embodiments, the dissolvable, edible, sheet (paper based or pva based) used, such as dissolvable, edible, sheet (paper based or pva based) 110, is configured to be less than 2 mm, 1 mm, 0.5 mm, or even 0.25 mm thick, so as to be sized to fit between the rollers of a configured fin seal machine, such as the fin seal machine disclosed in U.S. 2019/0029291, which is incorporated by reference herein. The machine preferably accepts a dissolvable, edible, sheet (paper based or pva based) 112, coats at least a portion of one side of the dissolvable sheet 112 with a dissolvable adhesive, such as dissolvable adhesive 114, folds the dissolvable, edible, sheet (paper based or pva based) about a consumable material, activates the dissolvable adhesive, and then applies pressure to both sides of the sheet about the dissolvable adhesive to seal the consumable material within the sheet. In other embodiments, two pieces of dissolvable, edible, sheet (paper based or pva based), such as dissolvable, edible, sheet (paper based or pva based) 310 and 320, are pre-treated with dissolvable adhesive before being fed into a machine, and are then placed around a consumable material, before having a pressure applied to the non-adhesive sides of the sheets (paper based or pva based) to form a seal, such as fin seal 306. In other embodiments, the machine could accept a flat sheet and could shape the sheet into a pocket, such as the pocket in dissolvable, edible, sheet (paper based or pva based) 420, and the machine could then deposit consumable material in the pocket before covering the opening of the pocket with dissolvable, edible, sheet (paper based or pva based) 410, which is then sealed to the surface of dissolvable, edible, sheet (paper based or pva based) 420 using a suitable dissolvable adhesives. Any suitable method could be used to form each of dissolvable packages 110, 300, 400, 500, and/or 600.
[0068] Additionally, any of dissolvable packages 100, 300, 400, 500, or 600 could be used to conveniently deposit consumable material in a container having a liquid beverage, such as water or juice, or coffee. If the package is provided as an elongated shaped package, such as package 600 (having a longer height 602 than width 604), then a user could mix a drink quickly by playing the elongated package 600 in a disposable water bottle. The package 600 could be configured to have a width 604 less than 1 inch or ½ inch, allowing the package 600 to be easily placed within a small mouth opening have a small mouth opening (e.g., having a diameter less than or equal to 1 inch) of the disposable water bottle. The user could remove a cap from the mouth of the water bottle. The user could remove (e.g., spill out or drink) some water from the water bottle to make room for the package 600 and the consumable material within package section 603. The user could slip the elongate package 600 through the mouth of the disposable water bottle after removing the small amount of water sufficient so that after the elongate package 600 is slipped into the water bottle, the water does not spill out of the mouth. The user could then close the water bottle with the cap, shake the water bottle to form a consumable mixed drink within the disposable water bottle. By way of example, not limitation, the package 600 could be filled with protein powder and, following the steps above, the user could form a mix drink of protein powder quickly since the water-soluble sheet (paper based or pva based) is dissolvable (preferably, the water-soluble sheet (paper based or pva based) is dissolvable in water under 30 seconds). The consumable material within the package section 603 could be mixed into water either homogeneously or heterogeneously. In the case of protein powder, the protein powder may be the consumable material and the mixed drink may be a nutritious protein powder drink. Alternatively, the consumable material may be dissolvable coffee. It is contemplated that the package may be provided as a square shaped package which may be dropped into a hot cup of water. Such a method could be used form a cup of coffee.
[0069] The beverage in which any of dissolvable packages 100, 300, 400, 500, or 600 is dropped in could have a temperature between 33 degrees Fahrenheit to 220 degrees Fahrenheit. By way of example, the beverage could comprise hot water that has a temperature between 130 degrees Fahrenheit to 180 degrees Fahrenheit and the package could contain dissolvable coffee. When the package with dissolvable coffee is dropped into a hot cup of water, the water-soluble sheet (paper based or pva based) dissolves and the dissolvable coffee is dispersed into the hot water to make a cup of hot coffee. In some embodiments, the beverage could be a hot coffee, and the package could contain an additive, such as powdered milk or sugar, which could then be tossed into the container with the hot coffee to dispense the additive in the beverage.
[0070] In some embodiments, a machine could be used to dispense a mixed beverage using an inventive dissolvable package comprising a consumable material. Such machines preferably have a package holder that is used to hold the package and mix the beverage while it is poured into a beverage container.
[0071] An exemplary package holder 700 is shown in
[0072] Package holder 700 could be configured for a machine and a package used with package holder 700. For example, the location of upper shoulder 728 could be adjusted to accommodate a pouring rate of the machine within which package holder 700 is placed and the dissolving rate of the package that is placed within package holder 700. For example, package that dissolves at a slower rate may necessitate a lower shoulder 728 than a package that dissolves at a higher rate, since a beverage will need to rest within upper reservoir 726 for a longer period of time before the package dissolves. In another example, a machine that pours at a faster rate may also necessitate a lower shoulder 728 than a machine that pours at a slower rate, as the upper reservoir 726 will tend to fill up faster when used in a machine that pours at a faster rate. Preferably, package holder 700 and the package used within package holder 700 are configured to allow a beverage to dissolves through the package and into lower reservoir 724 before upper reservoir 726 fills up at the pouring rate of the machine used.
[0073] In
[0074] An alternative package holder 800 is shown in
[0075] Reservoir 820 is substantially nut-shaped, having a width of an upper-section 828 substantially the same as a width of a middle-section 826, which drastically tapers to bottom section 822, where reservoir outlet 824 is located. By shaping reservoir 820 in a nut-shape taper, a shoulder having exact measurements for each package is not necessary, as the gradual taper could match packages of substantially any shape and size. For example, in
[0076]
[0077] Here, package holder 700 could be placed within dispenser 1120, which comprises cover 1122 and reservoir 1126, which can be opened and closed using lever 1128. A user typically places a dissolvable package, such as package 100 or package 300, within reservoir 720 of package holder 700, before placing package holder 700 within reservoir 1126 and closing cover 1122 using lever 1128. The user then places a cup 1150 under dispenser 1120 and selects an appropriate output of hot water to dispense using user interface 1130. Once the user instructs machine 1100 to dispense hot water with user interface 1130, hot water from water heater 1110 is dispensed through inlet hole 712 of package holder 700 to cover a portion of the dissolvable package, allowing the consumable material, such as dried coffee, to mix with the hot water and exit the outlet hole 729 of package holder 700 so that mixed beverage 1160 flows into cup 1150. As the dissolvable package dissolves within package holder 700, the mixed beverage empties into cup 1150. Preferably, the rate of flow of water through package holder 700 is controlled such that the entirety of the dissolvable package dissolves during the pouring step, ensuring that package holder 700 is empty and cleaned (with the hot water dispensed at the end of the pouring step) so that package holder 700 is ready to use after the mixed beverage 1160 is poured into cup 1150.
[0078] Variables, such as the rate that a dissolvable packet dissolves, could be used to design the package holder 700 and/or machine 1100 to ensure that the dissolvable packet fully dissolves at the end of the pouring step. For example, repeated experiments could show that a package holder fully dissolves when fully submerged within a package holder for at least 15 seconds. Using that variable, machine 1100 could be configured to dispense a volume of hot water (e.g. the volume of upper reservoir 726 of package holder 700), wait 15 seconds, and then dispense the rest of the hot water requested by the user via user interface 1130. Other experiments could show that a package holder fully dissolves when submitted to a hot water flow rate of one cup every 60 seconds, but does not fully dissolve when submitted to a hot water flow rate of one cup every 45 seconds. A designer could then configure the machine 1100 to slow down its rate of flow to one cup of hot water every 60 seconds. Another experiment could show that a dissolvable package only fully dissolves when submitted to beverage temperatures above 130 degrees Fahrenheit. A designer could then configure machine 1100 to only dispense beverages (e.g. hot water) above 130 degrees Fahrenheit when in use, or when a user selects the dissolvable package option via user interface 1130.
[0079] Dissolvable packets and/or package holders could be designed to allow for the same machine 1100 dispensing beverages in the same manner could result in different beverages being dispensed depending upon the dissolvable packet and/or package holder used. For example, in
[0080] In
[0081] In
[0082] In
[0083] In some embodiments, package 920 could also comprise a second sheet that sandwiches another dissolvable material between the sheets, such as packages 100 or 300. In such embodiments, package 920 is constructed allow the second sheet to dissolve before logo 924, which would allow the dissolvable material sandwiched between the sheets to dissolve within beverage 914 before logo 924 dissolves within beverage 914. Such embodiments are preferably designed to allow for lower-placed sheets to dissolve first before upper-placed sheets, allowing for a layered dissolving process that starts from the bottom of the package and ends at the top of the package. Using such embodiments allows for a gradual dissolving process that is controlled by the rate at which the dissolvable materials used by the package dissolve within liquid beverages and/or by the thickness of such dissolvable materials (e.g. two materials made of the same dissolvable materials will dissolve at different rates as a function of their thickness).
[0084] The above description is given by way of example, and not limitation. For example, an embodiment of a machine 1100 could be used without a package holder, where reservoir 1126 is configured to have substantially the same inner dimensions and features as reservoir 720 or 820. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein. Thus, the scope of the claims is not to be limited by the illustrated embodiments.
