DETAILED DESCRIPTION OF PREFERRED EXEMPLARY EMBODIMENTS
(26) The following detailed description of the invention is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
(27) Various embodiments of the present invention relate to fiber-based or pulp-base products for use both within and outside of the food and beverage industry. By way of non-limiting example, the present disclosure relates to particular chemical formulations of slurries adapted to address the unique challenges facing the food industry including oil barriers, moisture barriers, and water vapor barriers, and retention aids, the absence of which have heretofore prevented fiber-based products from displacing single use plastic containers and components in the food industry. The present disclosure further contemplates fiber-based containers having geometric and structural features for enhanced rigidity. Coupling these features with novel chemistries enables fiber-based products to replace their plastic counterparts in a wide variety of applications such as, for example: frozen, refrigerated, and non-refrigerated foods; medical, pharmaceutical, and biological applications; microwavable food containers; beverages; comestible and non-comestible liquids; substances which liberate water, oil, and/or water vapor during storage, shipment, and preparation (e.g., cooking); horticultural applications including consumable and landscaping/gardening plants, flowers, herbs, shrubs, and trees; chemical storage and dispensing apparatus (e.g., paint trays); produce (including human and animal foodstuffs such as fruits and vegetables); salads; prepared foods; packaging for meat, poultry, and fish; lids; cups; bottles; guides and separators for processing and displaying the foregoing; edge and corner pieces for packing, storing, and shipping electronics, mirrors, fine art, and other fragile components; buckets; tubes; industrial, automotive, marine, aerospace and military components such as gaskets, spacers, seals, cushions, and the like; and associated molds, wire mesh forms, recipes, processes, chemical formulae, tooling, slurry distribution, chemical monitoring, chemical infusion, and related systems, apparatus, methods, and techniques for manufacturing the foregoing components.

(29) With continued reference to
(30) In accordance with various embodiments the vacuum mold process is operated as a closed loop system, in that the unused slurry is re-circulated back into the bath where the product is formed. As such, some of the chemical additives (discussed in more detail below) are absorbed into the individual fibers, and some of the additive remains in the water-based solution. During vacuum formation, only the fibers (which have absorbed some of the additives) are trapped into the form, while the remaining additives are re-circulated back in vacuum tank. Consequently, only the additives captured in the formed part must be replenished, as the remaining additives are re-circulated with the slurry in solution. As described below, the system maintains a steady state chemistry within the vacuum tank at predetermined volumetric ratios of the constituent components comprising the slurry.
(31) Referring now to
(32) In a typical wet press process, the Hot Press Temperature Range is around 150-250 degree C., with a Hot Press Pressure Range around 140-170 kg/cm.sup.2. The final product density should be around 0.5-1.5 g/cm.sup.3, and most likely around 0.9-1.1 g/cm.sup.3. Final product thickness is about 0.3-1.5 mm, and preferably about 0.5-0.8 mm.
(33) With continued reference to
(34) The pulp fiber used in 202 can also be mechanically grinded to improve fiber-to-fiber bonding and improve bonding of chemicals to the fiber. In this way the slurry undergoes a refining process which changes the freeness, or drainage rate, of fiber materials. Refining physically modifies fibers to fibrillate and make them more flexible to achieve better bonding. Also, the refining process can increases tensile and burst strength of the final product. Freeness, in various embodiments, is related to the surface conditions and swelling of the fibers. Freeness (csf) is suitably within the range of 200-700, and preferably about 220-250 for many of the processes and products described herein.
(35) The chemical formulae (sometimes referred to herein as chemistries) and product configurations for various fiber-based packages and containers, as well as their methods for manufacture, will now be described in conjunction with
Produce Containers
(36)
(37)
(38) As briefly mentioned above, the various slurries used to vacuum mold containers according to the present invention comprises a fiber base mixture of pulp and water, with added chemical components to impart desired performance characteristics tuned to each particular product application. The base fiber may include any one or combination of at least the following materials: softwood (SW), bagasse, bamboo, old corrugated containers (OCC), and newsprint (NP). Alternatively, the base fiber may be selected in accordance with the following resources, the entire contents of which are hereby incorporated by this reference: Lignocellulosic Fibers and Wood Handbook: Renewable Materials for Today's Environment, edited by Mohamed Naceur Belgacem and Antonio Pizzi (Copyright 2016 by Scrivener Publishing, LLC) and available at https://books.google.com/book?id=jTL8CwAAQBAJ&printssec=frontcover@v=onepage&g&f=false; Efficient use of Flourescent Whitening Agents and Shading Colorants in the Production of White Paper and Board by Liisa Ohlsson and Robert Federe, Published Oct. 8, 2002 in the African Pulp and Paper Week and available at http://www.tappsa.co.za/archive/APPW2002/Title/Efficient_use_of_flourescent_w/efficient_use_of_flourescent_w.html; Cellulosic Pulps, Fibres and Materials: Cellucon '98 Proceedings, edited by J F Kennedy, G O Phillips, P A Williams, copyright 200 by Woodhead Publishing Ltd. and available at https://books.google.com/books?id=xO2iAgAAQBAJ&printsec=frontcover@v=onepage&q&f=false; and U.S. Pat. No. 5,169,497 A entitled Application of Enzymes and Flocculants for Enhancing the Freeness of Paper Making Pulp issued Dec. 8, 1992.
(39) For vacuum molded produce containers manufactured using either a wet or dry press, a fiber base of OCC and NP may be used, where the OCC component is between 50%-100%, and preferably about 70% OCC and 30% NP, with an added moisture/water repellant in the range of 1%-10% by weight, and preferably about 1.5%-4%, and most preferably about 4%. In a preferred embodiment, the moisture/water barrier may comprise alkylketene dimer (AKD) (for example, AKD 80) and/or long chain diketenes, available from FOBCHEM at http://www.fobchem.com/html_products/Alkyl-Ketene-Dimer%EF%BC%88AKD-WAX%EF%BC%89.html@.CozozvkrKUk; and Yanzhou Tiancheng Chemical Co., Ltd. at http://www.yztianchengchem.com/en/index.php?m=content&c=index&a=show&catid=38&id=124&gclid=CPbn65aUg80CFRCOaQodoJUGRg.
(40) In order to yield specific colors for molded pulp products, cationic dye or fiber reactive dye may be added to the pulp. Fiber reactive dyes, such as Procion MX, bond with the fiber at a molecular level, becoming chemically part of the fabric. Also, adding salt, soda ash and/or increase pulp temperature will help the absorbed dye to be furtherly locked in the fabric to prevent color bleeding and enhance the color depth.
(41) To enhance structural rigidity, a starch component may be added to the slurry, for example, liquid starches available commercially as Topcat L98 cationic additive, Hercobond, and Topcat L95 cationic additive (available from Penford Products Co. of Cedar Rapids, Iowa). Alternatively, the liquid starch can also be combined with low charge liquid cationic starches such as those available as Penbond cationic additive and PAF 9137 BR cationic additive (also available from Penford Products Co., Cedar Rapids, Iowa).
(42) For dry press processes, Topcat L95 may be added as a percent by weight in the range of 0.5%-10%, and preferably about 1%-7%, and particularly for products which need maintain strength in a high moisture environment most preferably about 6.5%; otherwise, most preferably about 1.5-2.0%. For wet press processes, dry strength additives such as Topcat L95 or Hercobond which are made from modified polyamines that form both hydrogen and ionic bonds with fibers and fines. Those additives may be added as a percent by weight in the range of 0.5%-10%, and preferably about 1%-6%, and most preferably about 3.5%. In addition, wet processes may benefit from the addition of wet strength additives, for example solutions formulated with polyamide-epichlorohydrin (PAE) resin such as Kymene 577 or similar component available from Ashland Specialty Chemical Products at http://www.ashland.com/products. In a preferred embodiment, Kymene 577 may be added in a percent by volume range of 0.5%-10%, and preferably about 1%-4%, and most preferably about 2%. Kymene 577 is of the class of polycationic materials containing an average of two or more amino and/or quaternary ammonium salt groups per molecule. Such amino groups tend to protonate in acidic solutions to produce cationic species. Other examples of polycationic materials include polymers derived from the modification with epichlorohydrin of amino containing polyamides such as those prepared from the condensation adipic acid and dimethylene triamine, available commercially as Hercosett 57 from Hercules and Catalyst 3774 from Ciba-Geigy.
(43) In some packaging applications it is desired to allow air to flow through the container, for example, to facilitate ripening or avoid spoliation of the contents (e.g. tomatoes). However, conventional vacuum tooling typically rinses excess fiber from the mold using a downwardly directed water spry, thereby limiting the size of the resulting vent holes in the finished produce. The present inventor has determined that re-directing the spray facilitates greater fiber removal during the rinse cycle, producing a larger vent hole in the finished product for a given mold configuration.
(44) More particularly,

Vent Hole Tooling
(47)
(48) With momentary reference to
(49) As seen in
Microwavable Containers
(50) Building on knowledge obtained from the development of the aforementioned produce containers, the present inventor has determined that molded fiber containers can be rendered suitable as single use food containers suitable for use in microwave, convection, and conventional ovens by optimizing the slurry chemistry. In particular, the slurry chemistry should advantageously accommodate one or more of the following three performance metrics: i) moisture barrier; ii) oil barrier; and iii) water vapor (condensation) barrier to avoid condensate due to placing the hot container on a surface having a lower temperature tan the container. In this context, the extent to which water vapor permeates the container is related to the porosity of the container, which the present invention seeks to reduce. That is, even if the container is effectively impermeable to oil and water, it may nonetheless compromise the user experience if water vapor permeates the container, particularly if the water vapor condenses on a cold surface, leaving behind a moisture ring. The present inventor has further determined that the condensate problem is uniquely pronounced in fiber-based applications because water vapor typically does not permeate a plastic barrier.
(51) Accordingly, for microwavable containers the present invention contemplates a fiber or pulp-based slurry including a water barrier, oil barrier, and water vapor barrier, and an optional retention aid. In an embodiment, a fiber base of softwood (SW)/bagasse at a ratio in the range of about 10%-90%, and preferably about 7:3 may be used. As a moisture barrier, AKD may be used in the range of about 0.5%-10%, and preferably about 1.5%-4%, and most preferably about 3.5%. As an oil barrier, the grease and oil repellent additives are usually water based emulsions of fluorine containing compositions of fluorocarbon resin or other fluorine-containing polymers such as UNIDYNE TG 8111 or UNIDYNE TG-8731 available from Daikin or World of Chemicals at http://www.worldofchemicals.com/chemicals/chemical-properties/unidyne-tg-8111.html. The oil barrier component of the slurry (or topical coat) may comprise, as a percentage by weight, in the range of 0.5%-10%, and preferably about 1%-4%, and most preferably about 2.5%. As a retention aid, an organic compound such as Nalco 7527 available from the Nalco Company of Naperville, Ill. May be employed in the range of 0.1%-1% by volume, and preferably about 0.3%. Finally, to strengthen the finished product, a dry strength additive such as an inorganic salt (e.g., Hercobond 6950 available at http://solenis.com/en/industries/tissue-towel/innovations/hercobond-dry-strength-additives/; see also http://www.sfm.state.or.us/CR2K_SubDB/MSDS/HERCOBOND_6950.PDF) may be employed in the range of 0.5%-10% by weight, and preferably about 1.5%-5%, and most preferably about 4%.
(52) Referring now to
Meat Containers
(53) Presently known meat trays, such as those used for he display of poultry, beef, pork, and seafood in grocery stores, are typically made of plastic based materials such as polystyrene and Styrofoam, primarily because of their superior moisture barrier properties. The present inventor has determined that variations of the foregoing chemistries used for microwavable containers may be adapted for use in meat trays, particularly with respect to the moisture barrier (oil and porosity barriers are typically not as important in a meat tray as they are in a microwave container).
(54) Accordingly, for meat containers the present invention contemplates a fiber or pulp-based slurry including a water barrier and an optional oil barrier. In an embodiment, a fiber base of softwood (SW)/bagasse and/or bamboo/bagasse at a ratio in the range of about 10%-90%, and preferably about 7:3 may be used. As a moisture/water barrier, AKD may be used in the range of about 0.5%-10%, and preferably about 1%-4%, and most preferably about 4%. As an oil barrier, a water based emulsion may be employed such as UNIDYNE TG 8111 or UNIDYNE TG-8731. The oil barrier component of the slurry (or topical coat) may comprise, as a percentage by weight, in the range of 0.5%-10%, and preferably about 1%-4%, and most preferably about 1.5%. Finally, to strengthen the finished product, a dry strength additive such as Hercobond 6950 may be employed in the range of 0.5%-10% by weight, and preferably about 1.5%-4%, and most preferably about 4%.
(55) As discussed above in connection with the produce containers, the slurry chemistry may be combined with structural features to provide prolonged rigidity over time by preventing moisture/water from penetrating into the tray.
(56)
(57)
Beverage Lids
(58) Although fiber and pulp based paper cups are widely known, the beverage industry still needs a sustainable fiber-based lid solution. A significant impediment to the widespread adoption of fiber-based lids surrounds the ability to incorporate a zero or negative draft into the lid, in a manner which allows it to be conveniently removed from the mold. In addition, the fiber-based chemistry must be adapted to provide an adequate moisture/water barrier so that the rigidity of the lid is not compromised in the presence of liquid. The methods, chemical formulae, and tooling contemplated by the present invention addresses both of these issues in a manner heretofore not address by the prior art.
(59) In particular, the chemistry for lids is similar to meat trays and microwave bowls discussed above. Specifically, for beverage container lids the present invention contemplates a fiber or pulp-based slurry including a water/moisture barrier and an optional retention aid. In an embodiment, a fiber base of softwood (SW)/bagasse and/or bamboo/bagasse at a ratio in the range of about 10%-90%, and preferably about 7:3 may be used. As a moisture/water barrier, AKD may be used in the range of about 0.5%-10%, and preferably about 1%-4%, and most preferably about 4%. Rigidity may be enhanced by Hercobond 6950 in the range of 0.5%-10% by weight, and preferably about 1%-4%, and most preferably about 2%. Kymene may also be added in the range of 0.5%-10%, and preferably about 1%-4%, and most preferably about 3%.

Lid Tooling
(62) A tool for making a fiber-based lid having a zero or negative draft comprises a retractable piston having a shape which generally to a mirror image of the lid, and which is configured to extend to unlock the finished lid from that part of the mold which the lid locks to.

(76) The present application also provides an environmentally responsible, sustainable solution for packaging flat screen televisions, monitors, and other delicate (e.g., electronic, artistic, glass) equipment already packed in its own box. This solution uses corrugated and fiber materials and, thus, avoids the use of non-renewable, single use plastics. In contrast to the telescopic configuration described above, the ensuing end cap solution provides a system for packaging rectangular boxes of virtually any size, using three different end cap sizes to accommodate different TV box heights, in combination with four different fiber corner cushions, using a sizing system which includes score lines on the end caps.
(77) In an embodiment, each end cap comprises a rectangular corrugated component having two pulp cushions, and score lines for adjusting the height of the finished end cap. The end caps are placed on either end of the original design manufacturer (ODM) box. A corrugated screen protector assembly including fiber feet is placed over the top middle of the box to protect the underlying screen from breakage during shipment. The ODM box, along with the end caps, screen protector, and corner cushions, is then assembled and surrounded with stretch wrap or palette straps to hold the entire pack together.
