The present invention relates to pouch having at least two compartments, one essentially empty and one for filling by a user to create a liquid to be consumed or used by a user or other person.
In the prior art, there are a number of different consumable liquid pouch constructions with frangible seals that are broken for mixing and creation of a liquid to be consumed. One example of such a construction is shown in U.S. Pat. No. 7,055,683 to Bourque et al., which is herein incorporated in its entirety by reference. In this construction two different flavored liquids are stored in the pouch. The frangible seal of the pouch can be broken such that the liquids can be mixed and then accessed via a fitment in communication with one of the pouches.
Another pouch designed for consumable liquids are those containing a powdered mix such as a margarita mix. These pouches have a single compartment and are designed to be filled with a liquid to create the desired beverage and then dispensed. One problem with these pouches is that the material inside the bag is that the material can be subject to oxidation and degradation over time. This is primarily because the surface to volume ratio is high inside the pouch. Also, the material inside these pouches can spill once the pouches are opened.
Problems with this type of pouch construction is that they offer the consumer only limited options in the type of liquid being created and made available. Therefore, there is a need to provide pouches, which are more flexible in the type of liquid that can be delivered. The present invention responds to this need by providing a pouch that allows a user to fill one of the pouch compartments to create a user-defined liquid for consumption or other use.
A first object of the invention is a pouch for providing a liquid to a user that can be consumed or used for other purposes.
Another object of the invention is a method of creating a usable liquid using the pouch.
Yet another object of the invention is a device for holding the pouch to facilitate consumption of the liquid contained therein.
Other objects and advantages will become apparent when reading the description of the invention as detailed below.
In satisfaction of the foregoing objects and advantages, the present invention provides, in one aspect, a pouch for dispensing of a liquid that can be either consumed by a user or other person, e.g., something that one would drink. The liquid could also be something that would not necessarily be consumed by a person, e.g., a cleaning or sanitizing liquid that could be used on by a user for personal use or to clean or sanitize some other object or the like. The term “usable” is meant to cover uses wherein the liquid formed in the pouch could be consumed by a user or wherein the liquid formed in the pouch would have a use that would not entail consumption by a person, e.g., cleaning, sanitizing, or the like of a person, animal, or inanimate object, surface, or a medical treatment.
The pouch further comprises at least first and second compartments, the first and second compartments separated from each other by a first rupturable seal; which ruptures upon application of a force so that the first and second compartments are in communication with each other.
The first compartment has a fill port, preferably with a tamperproof seal, and being empty or containing a gas such as air or an inert gas. The second compartment has at least a first material therein to be mixed with one or more liquids or solids to be introduced into the first compartment via the fill port to form the usable liquid.
In another embodiment, the pouch can comprise at least a third compartment separated from the first compartment by a second rupturable seal, the third compartment having at least a second material to be mixed with the one or more liquids and the first material for forming the usable liquid. The seals can be configured in a variety of locations between the various compartments, either horizontally, vertically or the like.
The pouch can include a gusset edge along one side of the pouch or some other means of support so that the pouch can stand alone.
Examples of the first material include a liquid concentrate of soup, tea, coffee, water purification compounds, tisanes, nutraceutical compounds, broth, effervescent agents, fruit drinks or nectars, a beverage mix suitable for mixing with alcohol, a powdered material such as a soup mix, pancake/waffle/biscuit mix, a powdered drink mix, medically-related materials that, when combined with the liquid provide some medicinal use, or any other type of product that can be used with a liquid to form a usable liquid. Another application would be to use a water activated foam in the sequestered compartment. This foam could expand on the order of 20-40 times its volume once mixed with water and the pouch could act like a sandbag. The liquid can be water or water and a combination of some other liquid such as alcohol.
The pouch can have a handle for carrying the pouch, wherein the handle can be a flap forming an opening between the flap and pouch, a through opening in the pouch material for gripping, and the like.
Another aspect of the invention is a method of creating a usable liquid. This method includes the steps opening the fill port and filling the first compartment with one of more liquids and closing the fill port. Then, the seal between the first and second compartments is ruptured so that the first material mixes with the one or more liquids to form the usable liquid for dispensing upon opening of the fill port. The method can also be employed with pouches that employ more than two compartments and more than one rupturable seal. Once the usable liquid is created, the liquid can be dispensed from the fill port for whatever use is appropriate. Examples of the liquid are those described above. Likewise, the first material can be the ones described above. When dispensing the usable liquid, the pouch can be held in a container so that the usable liquid can be dispensed from the fill port by gravity. The pouch can be provided with a stand alone feature so that it can be set on a surface and stand without any additional support for dispensing or storage. While it is preferred that the force is applied to the larger compartment, the force can be applied to either the first or second compartment or one of multiple compartments when more than two compartments are present.
Another aspect of the invention is a beverage pouch holder comprising a holder body having a top open end and a closed bottom, a slot at the top end adapted to receive a port of a beverage pouch, and an opening at the bottom adapted to receive the port of the beverage pouch; and optionally a lid adapted to cover the top open end and a handle to lift the holder when containing a beverage pouch.
The holder can further comprise a cup having a height less than a height of the holder, the cup adapted to fit within the holder body to receive a pouch in the cup or, in an inverted position, support a bottom of a pouch placed in the holder, or to support the bottom of the holder when the port extends from the opening in the bottom of the holder. The invention also entails a method of dispensing a beverage from a pouch comprising providing a beverage pouch with a port at one end thereof. The pouch is oriented in the holder so that the port is either in the slot or the opening for dispensing of beverage from the pouch. The port can be equipped with a dispensing tap when the port is in the opening.
The invention has a number of features which provide significant advantages over the prior art. One feature is that the inventive pouch comprises two or more compartments of which at least one compartment is void and the other compartment(s) are sealed and contain a liquid or powder concentrate. To the voided portion is attached a fitting with a removable cap or closure. When the user removes the closure and fills the empty compartment with liquid, preferably water, replaces the closure, and presses slightly on one or more parts of the pouch, e.g., the previously empty but now filled section, the force ruptures the seal(s) between the sections/compartments producing a beverage or other liquid ready for consumption or other use. The user needs only to again remove the cap and pour into a vessel for consumption, drink directly from the opening, or use in some other capacity.
Again, the invention has a number of significant advantages over the existing pouches available for providing a usable liquid. Beverages (non-carbonated), soups, dehydrated foods, water purification additives, and nutritional elixirs may be reduced in weight dramatically with the removal of substantially all of the water. This removal or reduction (known as concentrating) results in tremendous energy savings directly due to fuel conservation in transport, shelf space reduction (less space required to warehouse or display products), and lengthy shelf life or stability. Nearly all areas of the United Stated benefit from readily available and high quality potable water sources to add to the larger portion of the inventive pouch. In addition, other liquids may be added that are not reducible beyond a given level, e.g. alcohol and ice.
The package, constructed of flexible laminated material, allows for ease of storage when first mixed and increased flexibility as it is dispensed or consumed or otherwise used. The inventive pouch readily molds itself into areas where traditional vessels, due to fixed configuration, simply will not fit.
The package may be placed inside a thermal protective housing to accept boiling or very hot liquids for soups or hot served beverages such as cocoa or coffee. Additionally the package may be frozen to be consumed or used at a later time still cold. If the package is placed in the thermal sleeve, then melting is retarded and the package may take some time to fully thaw. This is ideal for extended trips.
Since the package is constructed of very lightweight plastic-based laminates, it poses no risk or danger for areas such as beaches, pools, playgrounds etc. as glass and metal do. The package may be recycled by plastics recyclers that specialize in reusing traditionally non-recyclable materials by shredding, melting, or transforming into new objects. One example of such an entity is TerraCycle Corporation.
Since an average liquid concentration factor is at least 11+1, the use of the invention realizes a savings of no less than 11/12 of the transport energy and 11/12 of the material required if 12 separate containers were used. If dried materials are utilized the savings are far greater. Since a good and readily available recycling methodology exists, the inventive pouch is indeed a full circle application.
The pouch is comprised of layers or laminates of plastic material which are fused together to form a multi-compartment pouch as is known in the art, see the Boudreau patent mentioned above as one example. Separate formed section(s) within the pouch are filled with a concentrate (either liquid or powder) while a larger section is empty, save for air or inert gas or a vacuum. The larger area has affixed to it a fitting, preferably with a tamper-evident closure, that provides the means to seal the pouch from contaminants until its use. The user removes the closure, breaking the tamper evident seal, and fills the empty section with liquid, preferably water, replaces the closure, and places a slight pressure on the now filled section, causing the sealed compartment(s) to rupture and mix with the liquid. Of course, the liquid may be hot or cold and the user may add ice into the opening to chill the final product.
The materials of the pouch can be any materials that are suitable for holding the intended material for the compartments. Likewise, the fill port can be any type of a closure that would be adaptable for connection to the plastic materials used to make the pouch and can be placed in various locations on the pouch. Examples include just screw caps or taps such as found in wine-in-a-box products. The pouch can also include the appropriate printing and the like for advertising, meeting government regulations, directions, etc. In one embodiment, the pouch can be made so that one side is clear so that the contents of either compartment can be seen. The other side can be designed to accept printing so that the appropriate advertising, product details, nutrition facts, etc. can be displayed.

In yet a further alternative, the rupturable seals could be serial in nature such that the third compartment would be separated from the second compartment by a rupturable seal and the second compartment would be separated from the first compartment by a rupturable seal. This embodiment is shown in
Additionally, holders are designed into which the pouch may be placed to facilitate filling and dispense. These holders may be formed of a double-wall construction allowing the entrapment of insulation material or refrigerant such as “blue-ice”. One holder has the versatility to allow normal pouring such as a pitcher, but when the fill port is replaced with a “tap” and placed top side down, the holder acts as a reservoir for easy dispense. A fill port or tap can be removed and reserved to facilitate complete drainage when used in this position.

With reference again to
Compartment 5 may also be subdivided into sections requiring varying degrees of force to break the seal. This is very useful in the application of user-preferred additives such as sweetener, flavoring, coloring and other enhancements. In this mode, one seal between two compartments may break initially to create an initial mixing of the liquids and another seal with a third compartment could rupture later so that the material in the third compartment is not mixed until the liquid and first material are mixed.
In operation, one exemplary method, referring again to
a. The user removes a cap or protective covering from the spout or orifice.
b. The user introduces the material or media to be mixed into compartment 3, such as water, milk, liquor, fruit, flavor, ice or a combination of any of these.
c. The user places sufficient pressure on one or the other filled portion, preferably the larger portion, to rupture the temporary seal or seals separating the sequestered material in compartment 5 and the media in compartment 3.
d. The user then manipulates the now combined portion so as to finish blending and mixing the components to satisfaction.
e. The user then removes the cap or covering from the orifice and dispenses the product easily by grasping the surplus material that results when the previously separated portions are now combined and pours into serving vessels such as cups or glasses or onto cooking surfaces or the user may consume or use the product directly from the orifice. Ice and other additives are readily inserted into the orifice if desired.
The mixed components may be poured or squeezed from the inventive pouch by removing the cap or covering or by affixing a “faucet” to the opening and pouring by operating the faucet. This feature is particularly useful in the larger (5 liters and above) pouches typically employed in food service operations.
One or more of the sealed compartments may contain liquid beverage concentrates of any non-carbonated nature, soups, isotonic, water purification compounds, nutraceutical compounds, effervescent agents, broth, or other food type products. Other uses include: (1) beverages such as liquid concentrates, e.g., teas, tisanes, nutraceuticals, fruit (fresh and frozen) as well as powdered drink mixes; (2) soups such as liquid concentrated broths, clear and with solids, as well as powdered; (3) bar mixes, specialty bar mixes, liquid, powdered and frozen concentrates to which alcohol, water, and other fresh ingredients are added, which may be frozen into slush and served, a sangria mix to which wine is added make a party or summer drink; (4) food: powdered products such as pancake/waffle or biscuit mixes only require the addition of water into the bag to fully prepare the dough-based product for cooking; (5) cleaning/sanitizing materials such as powdered or liquid detergent, disinfectants, and the like that could be used once made for the purpose of treating people, animals or inanimate objects; (6) medical such as dosed media, foodstuffs or beverages to provide small and large scale preventive or curative dispense in relief areas or disadvantaged populations; and (7) water-activated foam in the sequestered compartment; this foam could expand on the order of 20-40 times its volume once mixed with water and the pouch could act like a sandbag.
Other applications that may utilize the inventive pouch include the following.
(i) Disaster—in the event of a large scale disaster, it is far easier to transport hundreds or thousands of gallons of potable water in tankers to a remote site than thousands of cans or bottles of ready to drink or eat containers. The water can be placed into compartment 3 quickly and mixed effectively for immediate use. The empty pouch collapses to a fraction of its size therefore facilitating bulk removal from the site. Water can be bulk heated through many common methods and placed in pouches designed for thermal applications.
(ii) Military operations—due to the extreme light weight of the pouch, emergency rations can be ferried for great distances during operations until water or other intended media is available. With the inclusion of water purification sections, safe water can be made available prior to bursting the concentrate portions.
(iii) Camping/hiking, wherein the lightweight fully contained pouch provides for readily available beverages and food during backpack, canoe, or camping ventures. Again, if water purification is added, the user has complete nutrition at hand, or if only the water purification is included, clean drinking water. The collapsible quality of the inventive pouch makes for complete “pack it in, pack it out” functionality.
(iv) Recreation—for use in all outdoor events such as boating, beaches, tail-gate parties, picnics and the like all the functions of the inventive pouch are in play.
(v) Homeland Security—entire collections of beverage, food, medicine and pure water can be packaged in emergency use containers in the event that traditional supplies are cut off. Additionally, while not a prime use of the inventive pouch, during an isolating emergency event, the empty pouch can be used to effectively store and later dispose of human waste.
The pouch may be formed of any given size desired, with examples being 1, 2, 4 and 10 liter sizes. The smaller sizes can be used in a stand alone condition, with the larger sizes possibly requiring holders such as the one depicted in
While numerous products may provide concentrate for use, the inventive pouch is singularly unique in providing the entire vessel for transport, mixing, consumption/use and recycle. The inventive pouch requires the addition of mix media into the package by the user to make the product usable. No other product is required or needed for pouch operation other than a temporary housing for safety when used for heated products. The pouch is not limited to food and beverage applications as are stated herein and can be applied in a number of other and useful applications.
As such, an invention has been disclosed in terms of preferred embodiments thereof, which fulfills each and every one of the objects of the present invention as set forth above and provides new and improved pouch, a method for dispensing liquids from the pouch, and a holder for the pouch.
Of course, various changes, modifications and alterations from the teachings of the present invention may be contemplated by those skilled in the art without departing from the intended spirit and scope thereof. It is intended that the present invention only be limited by the terms of the appended claims.
This application claims priority under 35 U.S.C. 119(e) based on provisional patent application No. 61/193,273, filed in Nov. 12, 2008 and which is incorporated in its entirety by reference herein.
