The benefit under 35 U.S.C. §119(e) of U.S. provisional patent application Ser. No. 61/421,495 filed Dec. 9, 2010, the entire disclosure of which is incorporated herein by reference, is claimed.
BACKGROUNDA problem with current dairy and juice packaging is that virtually all of the materials associated with distribution, retailing, and use are single-use, in that the entire consumer purchased container is disposed of in either recycling or trash (with the exception of returnable dairy crates & pallets, and glass dairy bottles in limited use in some areas). There is a significant amount of monetary resource committed to a full featured container. This is includes the necessary materials to fulfill both the structural/mechanical and the content preservation roles.
Current options in many areas are blow-molded plastic (HDPE or PET, PP) bottles, laminated paperboard packages from TetraPak, (TetraBrik, TetraTop, etc), SIG, EloPak, gable top cartons etc. While most options are technically recyclable, there is wide variety in access to recycling facilities for consumers globally which reduces the actual recyclability of the packages. Laminated packages are often of very dis-similar materials and excessively complex, or require high energy use, to separate into more usable single material streams.
While the CPG (Consumer Packaged Goods) industry is aggressively pursuing sustainability initiatives, more can be done to reduce the amount of virgin material used in single-use packaging, and in un-recyclable packages. CPGs are light-weighting packaging and products across the board. Even for the packaging materials that are recyclable however, many are not recycled, because there is not equal access to recycling facilities in every municipality.
SUMMARYDisclosed is an environmentally efficient packaging/delivery system that is cost effective, carbon effective and readily recyclable while being very usable for dispensing liquids (primarily dairy and juice) in consumers' homes. The system leverages light-weight flexible refill pouches with resealable closures that are securely installed in re-usable carafes in the home. Single-use packaging is reduced as light-weight flexibles are used as distribution and retail packaging, and a durable carafe is used repeatedly.
INCORPORATION BY REFERENCEAll publications, patents and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent or patent application was specifically and individually indicated to be incorporated by reference.
Although the following text sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words of the claims set forth at the end of this patent. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims.
It should also be understood that, unless a term is expressly defined in this patent using the sentence “As used herein, the term ‘______’ is hereby defined to mean . . . ” or a similar sentence, there is no intent to limit the meaning of that term, either expressly or by implication, beyond its plain or ordinary meaning, and such term should not be interpreted to be limited in scope based on any statement made in any section of this patent (other than the language of the claims). To the extent that any term recited in the claims at the end of this patent is referred to in this patent in a manner consistent with a single meaning, that is done for sake of clarity only so as to not confuse the reader, and it is not intended that such claim term by limited, by implication or otherwise, to that single meaning. Finally, unless a claim element is defined by reciting the word “means” and a function without the recital of any structure, it is not intended that the scope of any claim element be interpreted based on the application of 35 U.S.C. §112, sixth paragraph.
It is clear that consumers are supporting the environmental initiatives where these options are generally cost competitive while still offering a level of product functionality that remains high and meets expectations. FTC, SPC, and other regulatory bodies are beginning to stipulate that package labeling clearly communicates the TRUE recyclability of the package's materials in the region where it is used. In addition, significant retailer initiatives are underway to minimize packaging materials or simplify package so that there are a greater number of good quality end of life options for materials reuse.
An approach to reduce the amount of single-use packaging in dairy products is to increase the proportion of reusable components relative to single-use components. It is critical to address this opportunity through consideration of a system that reaches from producers though distributors & retailers to consumer's homes and through to participation in recycling programs and re-processing of waste materials.
There are several functions of a package for dairy products. First and foremost, it must ensure product safety through the stated shelf life. To do this, it has a barrier component, a closure component, and a structural component. The laminate paperboard structures such as Tetra packages, the barrier and structural component are laminated to one another into a single-walled paper-based structure. In a blowmolded bottle, the functions of structure and barrier are performed by a single-walled structure. There is a problem with this approach, since barrier properties and structural integrity are derived from different types of materials. When materials are comingled or laminated, they are more difficult to recycle.
The described holding system 100 separates the functions of barrier from the function of structure. Since the pouch (barrier) 120 is not required to provide structural characteristics, it can be thinner, and use less virgin material to produce. In many countries, a durable, reusable carafe 110 is paired with a single-use refill pouch. 120. The pouch 120 is purchased on the usual high frequency, repeat basis. The carafe 110 stays at home (at the point of use) and initially is either purchased by the user or is given to the user free as a promotional item.
the pouch 120 is a simple pillow-pouch (VFFS, etc) with no fitment 140 or spout. The corner is removed with scissors and it is not possible to re-close the pouch 120 between uses.
the carafe 110 could be a very simple open-top jug or a complex, multi-part jug.
A carafe 110 and pouch 120 system scores very high on sustainability rankings. Significant contributing features include lightweighting of single-use items due to a reusable structural component. As a result there is a reduction of energy inputs on the manufacturing side. With high product to packaging ratio, the distribution system energy costs are expended on moving and merchandising product.
There are short comings inherent with the current pouch and carafe system that contribute to its limited consumer acceptance. First, there is a need for a cutting device to open the pouch. If the cutting device is absent there is a barrier to entry. In addition, there is no way to close the cut opening. Once the pouch is open, it stays open as there is no sealing or closing mechanism. The size of the corner cut has a significant affect on the actual pouring characteristics. This can range from slower or faster than desired. The cut also may be a rough cut and this can result in an unpredictable stream of exiting liquid. Errors lead to spills, waste and a less than satisfactory user experience. In addition, the opened pouch may be unstable at the upper end and may shift during the pouring process. It is not uncommon for the opening to shift during pouring as the user tilts the carafe and the content load then shift to the orifice end of the pouch.
Shortcomings with other types of systems that have sought to improve upon the carafe and pouch system. Jugit is an example and it is complex, finicky, material-intensive, requires cleaning, has loose parts, requires assembly on-shelf or in the user's home or other space.
There are some systems 100 where the pouch 120 is dropped into a jug with a piercing member in the bottom, and the pouch 120 opens, releasing the milk into the jug. The pouch 120 is removed, and the milk is dispensed from the jug. The down sides are that the jug requires cleaning, emptying the pouch is potentially messy and keeping the milk “clean” is a challenge. Even existing bottles also have shortcomings. Due to the single use nature and the desire to minimize materials and overall shipping volume to reduce cost, handles on typical HDPE milk jugs are often undersized. This, in combination with the opening size, can result in sloshing and sudden dispensation of liquids.
The carafe system 100 contemplated herein includes a carafe 110 or container with integrally molded receiving features 130 for a fitment 140 on a pouch 120. The carafe 110 nests for efficient shipping and storage prior to sale to customer. The carafe 110 could be made from injection-molded plastic, as an example and not limitation, the plastic could be PP, HDPE, ABS, etc. Of course other manufacturing methods and materials are possible and are contemplated.
The carafe 110 may be blow molded plastic, and molded entirely closed, with spout snap-in features die-cut out of the enclosed area afforded by the blowmolding process. In other embodiments, the carafe 110 could be sheet metal, ceramic, glass, or any other material well-suited to the kitchen environment. Of course other materials are possible and are contemplated. About the only limitation on the material is that it be capable of holding a liquid of a weight that is appropriate for the volume of the container or carafe 110. This carafe 110 and pouch 120 system in not meant to be limited to certain materials or processes.
The pouches 120 may be produced in several volume capacities. By example and not limitation, in the following volumes: 0.5 L, 0.75 L, 1.00 L, 1.3 L 1.5 L, 2.0 L etc. are possible. The pouch 120 may be lightweight and flexible and could be made from one type of plastic resin (LDPE, LLDPE, HDPE, blends etc.). The lightweight flexible film pouch 120 and fitment 140 could both be made from the same family of resins. As an example and not limitation, the pouch 120 and the fitment 140 could both be made from LDPE. As another example and not limitation, the pouch 120 could be made from a mostly LDPE film with barrier layers of other materials suitable for dairy packaging and with an appropriate sealing layer and the fitment 140 could be made from LDPE.
The pouches 120 to be used in the carafe 110 can be made by VFFS (Vertical Form Fill and Seal) process with fitment 140 installation, HFFS (Horizontal Form Fill and Seal) with fitment installation or platen forming with fitment 140 installation. The pouches 120 could be pillow style or be formed into flat bottom pouches, sidewall pouches, side weld, etc. The pouch 120 film could be single material such as a Polyethylene or constructed as a laminated film structure. In addition, the film could be a co-extrusion alloy of more than one type of plastic. Film materials could include, but are not limited to, HDPE, LDPE, PP, PET, Nylon, Metallocene, LLDPE, etc. Pouches 120 could be multi walled (i.e., two thin layers make each wall) but a preferred embodiment may be a single walled material. Pouches 120 could also be made by a thin wall extrusion blow molding (i.e., windshield washer fluid containers) process or injection stretch blow molding (similar to PET Coke® bottles) with and integrated fitment 140. These could be layered structures or single wall structures with a range of material option.
The pouch 120 could have features in the film, formed by a combination of thermal welding or ultrasonic welding and or die-cutting, that assist with or promote the following (the features could include holes, sealed flat areas, formed loops, slits, die-cuts, calendared textures, profiled edges, etc):
merchandising,
handle for picking up, carrying, inserting into carafe 110
insertion to carafe 110,
locking into carafe 110,
better evacuation of beverage from pouch 120 when in carafe 110,
structural integrity of carafe 110 when pouch 120 is installed.
The pouch 120 also could be a simple pillow-pouch style (essentially flat when not filled). The pouch 120 also could have formed/overlapped/shaped areas to assist withstanding up on shelf for merchandising or storage in refrigerator in the home and the pouch 120 may fully-deploy and fill the internal volume available in the carafe 110, providing friction or other mechanical means to improve retention in the carafe 110 and promote evacuation of beverage from pouch 120.
The carafe 110 may be of virtually any shape. Of course, the carafe may be designed to hold a pouch of liquid. The carafe cannot be so thin that a pouch cannot be inserted. As illustrated in
In
The carafe 110 may have a window 500 (
The carafe may also be designed to fit into a regionally appropriate refrigerator. As an example, the door on a US refrigerator may accept a 6 inch wide and 12 inch tall container. Logically, the carafe may be 6 inches wide and 12 inches tall.
The carafe 110 may include a receiving feature 130 for receiving a fitment 140 on a re-closeable liquid containing pouch 120 where the receiving feature 130 allows the fitment 140 to be securely held to support the pouch 120, may assist in resisting twisting of the pouch 120, may bring the pouch/fitment 140 in working position, compared to its natural manufacturing position/orientation/angle and may allow the release of the fitment 140 if desired. The carafe's receiving feature 130 may be cylindrical in shape, arranged with its axis at some angle to the long axis of the carafe 110, so as to position the fitment 140 in an optimal use angle and position. The receiving feature 130 may also position a lug on the fitment 140, for the purpose of preventing rotation during capping/uncapping. The receiving feature 130 may have an open end slightly smaller than the maximum outside diameter of the fitment 140 (“E” dimension). Due to the flexible and compliant nature of the fitment 140 material and the carafe material 110, this restricted opening allows insertion of the fitment 140, but provides resistance to removal of fitment 140. The receiving feature 130 may be integrated to any carafe 110 design/material. A non restricted opening is also contemplated where the fitment inserts easily and is release-ably retained to the carafe with and additional feature such and a snap, a sliding lock, a threaded collar.
The receiving feature 130 may be a separate part that is purchased (by a carafe-manufacturer) and assembled to match the fitment 140. Similarly, the rights to the receiving features may be purchased for manufacture or directly incorporate the features into the carafe by the carafe manufacturer. The receiving feature 130 may be produced in a manufacturing method that allows high tolerances required for proper engagement with features of a pouch fitment 140 and assembled to a carafe 110 produced in a manufacturing method with that produces parts with lower tolerances. Of course other methods for retention of the fitment are possible and are contemplated.
The carafe 110 could have fitment 140 snap-in features 700 that are molded in a first position and shipped in that position, efficiently nested.
The fitment has a cylindrical body, with a welding flange at an end and at another end, threads or other features to receive a closure. There could also be an integrally-molded closure, or an integrally-molded closure on a flexible strap. There are features (ribs, protrusions, flanges etc) for secure fit with the inside surface of the container when fitment is in use position. There is a feature to prevent rotation during capping/uncapping, which fits into a receiving feature in the carafe. This could be a lug, block, rib, etc. The fitments could be made of a range of materials, including PP, LDPE, HDPE, LLDPE and they can be attached to the pouches by heat welding, ultrasonic welding, or other processes. Of course other features for facilitation of insertion and for retention of the fitment are possible and are contemplated.
The fitment 140 may be reclose-able, such as with a flip cap or a screw cap 3100. The fitment 140 on the pouch 120 may also have tamper-evident seal and a re-usable closure. The fitment 140 may also have features that securely snap in to and engage with the receiving feature 130 on the carafe 110. The fitment 140 may be facemounted or edgemounted to the pouch 120. Face-mounted fitments are described in U.S. Pat. Nos. 6,237,308, 5,288,531,4,709,528, 7,076,935, 6,874,299, 6,826,892, 6,794,053, 6,237,308, 5,363,966, and U.S. Patent Application No. 20060111224, which are incorporated herein by reference in their entirety.
The fitment 140 may also have features such as holes, hooks, snaps, ridges, fins, flanges, etc. for improving merchandising options, securing fitment 140 to carafe 110, guiding fitment 140 into correct location/position/orientation in carafe receiving feature 130, providing audible feedback when the fitment 140 is locked into place in carafe 110, providing tactile feedback when the fitment 140 is locked into place in carafe 110, providing a location for hang-tag or other labeling for any purpose, creating a hanging pouch 120 from features in carafe 110, stabilizing the top of the pouch 120 while the pouch 120 rests in carafe 110, providing a hang pouch 120 on a shopping cart during transit from dairy case to checkout to car, etc.
In some embodiments of the fitment 140 used in the carafe 110, the same fitment 140 could be designed to fit into a molded pulp shell; the resulting rigid vessel 100 with polymer liner could be suitable for distribution, retailing, and dispensing of beverages or other fluid or aggregate materials for engagement to a pulp molded bottle shell 110. This could leverage tooling capital, suppliers, distribution, etc in place for one type of package (the refill pouch 120 for carafe 110) for use in another type of packaging.
The fitment 140 may provide secure closure after initial opening and the fitment 140 could provide medium-level of security in closure after initial opening. In addition, the fitment 140 could, through color variations, communicate different products carried in the pouch 120 (e.g.: blue fitment could mean Skimmed Milk, pink fitment could mean 2% Milk, white fitment could mean 3.25% Milk, or any other designated product, according to the dairy/retailer's current color scheme). The fitment 140 could promote complete evacuation of beverage from pouch 120, without undue rotation of package 110 and the fitment 140 could prevent pouch 120 from falling out of carafe 110 when pouring the last part of beverage out (and when carafe 110 may be upside down).
The fitment 140 may be made from a single material, may be made in a single part and may be closed with a separate closure (screw-type, snap, etc). The fitment 140 may also be in a single part including an integral tamper-evident device; and have a separate closure. The closure could be a snap-type closure, molded in a first “open” position, then moved into a second “closed” position for distribution, retailing, and use. The second “closed” position could also create the appropriate closure after the package is first opened by the user.
The pouches 120 may be sold in multi-packs of 2, 3, 4 or more pouches of various capacity (e.g.: 3×1.3 L pouches). Multi-pack configurations could result in total volumes typically sold in dairy: ½ gallon, 1 gallon, 2 gallon, etc. Multi-packs could be packed in thin polymer bags (as in Canada); the bags could be thin LDPE. This gives the multi pouches double wall security and can immobilize fitments and keep them from abrading neighboring pouches.
The multi-packs may be secured with a strap that also functions as a carry/hang handle. Other methods of securing and merchandising multi-packs are possible and are contemplated.
The pouches 120 could be stored hanging from the fixtures on the door, both before they are opened, and after they are opened, but before they are consumed completely. The user could store the partially-used pouches 120 in the refrigerator, and only put the pouch 120 that they needed into the carafe 110 when they needed to use it. Several products would be available for purchase in the refill pouches 120 (milk, juice, etc). This could safe refrigerator space for storage.
The benefits of the described liquid holding vessel 100 are many. At a high level, less trash may be created as more of the liquid delivery vessels will be recycled. In addition, the described embodiments may create a clean and safe device that is easy and reliable to use for transporting and dispensing liquids. Users will be pleased with the ease of use, reliability and re-use-ability of the described vessel 100.
