[0087] The non-limiting embodiments described herein are with respect to containers with hinged lids and methods for making the containers with hinged lids. The containers with hinged lids and methods for making the containers with hinged lids may be modified for a variety of applications and uses while remaining within the spirit and scope of the claims. The embodiments and variations described herein, and / or shown in the drawings, are presented by way of example only and are not limiting as to the scope and spirit. The descriptions herein may be applicable to all embodiments of the containers with hinged lids and methods for making the containers with hinged lids.
[0088] Disclosed herein are implementations of containers with hinged lids and methods for making the containers with hinged lids. The implementations shown arc illustrative and other implementations are within the scope of the specification and claims described herein. Forpurposes of illustration, certain aspects, features, and the like are described with respect to implementations. These aspects, features, and the like arc appropriately applicable to and interchangeable with other implementations described herein.
[0089] In implementations, the containers with hinged lids described herein can be manufactured using combinations of injection molding (IM), in-mold labeling (IML), die cutting, compression blow molding, thermoform molding, and the like processing (collectively “structure forming process”) to form containers with hinged lids and the like (collectively “containers with hinged lids”) with mechanical attachment means (collectively “join processing”) to attach the container with a lid to create containers with hinged lids which can hold content or materials. In implementations, the containers with hinged lids can be configured to contain liquid, concentrated liquid, powder, granules, dry content, or non-dry content or materials, for example.
[0090] In implementations, the containers with hinged lids can be made using the structure forming processes from polymers, sustainable materials, recyclable materials, biodegradable materials, bio-based resins, weight-optimized biodegradable plastic, molded fiber, molded paper, molded pulp, fiber, paper, pulp, paperboard, pressed pulp, fiber based, pressed fiber, paper, starch, cellulose, recycled plastic film, metals, metalized film, biodegradable resins such as Polylactic acid (PLA), Polyhydroxyalkanoates (PHA), Polyhydroxybutyrate (PHB), Polyethylene Furanoate (PEF), and combinations thereof.
[0091] In implementations, the containers with hinged lids can be made using the structure forming processes from sustainable materials which can include at least one of recyclable materials, biodegradable materials, bio-based resins, weight-optimized biodegradable plastic, molded fiber, molded paper, molded pulp, fiber, paper, pulp paperboard, pressed pulp, fiber based, pressed fiber, paper, starch, cellulose, recycled plastic film, biodegradable resins, polylactic acid, poly hydroxy alkanoates, polyhydroxybutyrate, or polyethylene furanoate.
[0092] In implementations, the lid can be made using the structure forming processes from polymers, sustainable materials, recyclable materials, biodegradable materials, bio-based resins, weight-optimized biodegradable plastic, paperboard, pressed pulp, heavy film, film, fiber based, pressed fiber, paper, starch, cellulose, recycled plastic film, metals, metalized film, biodegradable resins such as PLA, PHA, PHB, PEF, and combinations thereof.
[0093] In implementations, containers with hinged lids can include a barrier layer or film on an internal or inside surface, where the barrier layer is impervious or substantially impervious tothe content or material in the containers with hinged lids and / or chemically inert or substantially chemically inert with respect to the content or material in the containers with hinged lids. In implementations, the containers with hinged lids can include an integrated or integrally formed barrier layer or film. In some implementations, the barrier layer can include one or more of an oxygen barrier, a moisture barrier, a grease barrier, a gas barrier, an oil barrier, and other barrier relevant to the content or material in the containers with hinged lids. In some implementations, the oxygen barrier, the moisture barrier, the grease barrier, the gas barrier, the oil barrier, and the other barrier can be integral to or integrated with the barrier layer. In some implementations, the oxygen barrier, the moisture barrier, the grease barrier, the gas barrier, the oil barrier, and the other barrier can be separate layers formed on the barrier layer.
[0094] In implementations, the containers with hinged lids can efficiently use recyclable, biodegradable, and the like materials for improved sustainability.
[0095] The containers with hinged lids and methods described herein are environmentally friendly, compostable, and recyclable. The containers with hinged lids can be filled with powders, granules, or concentrated liquids which are sealed with a lidding, membrane, or film (collectively referred to herein as “lidding”).
[0096] In implementations, the containers with hinged lids and components thereof can be molded into a variety of shapes using the described and / or disclosed materials and can be laminated or coated on an internal or inside surface with a barrier material and sealed with a lid which can be hinged for multiple open and close operations.
[0097] Described herein is a multi-part container and lid system that can be assembled at the filling site. During assembly, elements of the lid are connected with elements of the tub to create a hinged connection suitable for one or more use cycles. The lid may stay closed with a single or multiple latch system. The tub may be sealed with a lidding material before, during, or after the lid is installed. The container, lidding, and lid may exhibit barrier properties that reduce the transfer rate of gas, liquid, or solid materials to increase enclosed product material stability over time. Because of the desire for sustainable and recyclable options, a molded fiber tub with reclosable lid is needed.
[0098] In implementations, tubs are used for products like dishwasher tabs, laundry tabs, or other granular materials. Some of these materials are pre-dosed, and some are provided in a form that could require dosing with a separate measuring device. The measurement device or scoopmay be provided to end consumer in a storage area. The storage area might be generally enclosed by the lid or closure system.
[0099] The filling environments and equipment for tubs for tabs typically cannot accommodate a container with a connected lid during filling. They may require the lid to be applied to the container after the container is filled with product.
[0100] The use of tabs tubs includes a hinged lid with a reclosable latch. These containers can be opened with 1 hand or they can require the use of two hands. The closing system may include child resistant features. One example of a child resistant closure system is a system where two latches must be opened at the same time to open a container. The latches may be situated at a distance from one another, such that two hands are required to release the latch system and open the container.
[0101] Products sold in tubs may require barrier properties that restrict the flow of oxygen, water vapour, or solid particulate materials to ensure the performance of the product for the expected shelf life. The barrier characteristics of the tub may be provided by chemistry in the fiber slurry, coatings on the surface of the tub, a laminated material on the surface of the tub, a separate barrier-providing liner or bag, or a combination of these. The tub may require a sealed closure that is separate from the lid. The sealed lidding may be comprised of a polymer film, barrier-coated or laminated paper, or a combination of materials. The lidding may be sealed onto an open side of the tub after the tub is filled with product. The lidding material may be applied before the lid is applied to the tub. The lidding material may utilize a peelable seal that allows the lidding to be removed before initial use without damaging the barrier characteristics of the tub or lid.
[0102] In implementations, a container lid may be molded in a shape that provides areas suitable for bending or deformation. The lid part may be made from molded fiber or assembled from more than one component. The components may be comprised of materials from the family of cellulosic materials from wood or non-wood sources, and / or polymers, including biopolymers. The features may be integrally-molded or overmolded or assembled through bonding with adhesives, snap features, fasteners etc.
[0103] In implementations, the interconnecting hinge features may snap into place or get forced into position with automated operations or manual operation on the filling line. The features may be created net-shape (requiring no transformations) or be created with requirementof transformation or manipulation during assembly. The hinge features or latch features may require molding, mechanical deformation, or trimming operations to create the features.
[0104] In implementations, the assembly of the hinge features may be achieved with a single direction of travel during assembly. For example, the lid may be placed on to a face of the container in generally the final orientation, and be pressed into final position. It could be pressed into position with an automated machine with custom tooling, or be pressed into position with manual operation (by hand, by an operator).
[0105] In implementations, the lid may be assembled to the tub when in the open position. In this case, the hinge features may be arranged with preferable assembly direction when the lid is in the open position (with the lid’s sealing surface at 60-, 70, 80, 90, 100, 110, 120-deg from the tubs sealing surface). Once the hinge features are engaged in the open position, the lid may be rotated to its final sealed position (with the sealing surface parallel to the tubs sealing surface) to complete the assembly.
[0106] How the hinge gets installed
[0107] In implementations, the hinge features may require temporary or permanent deformation of features on the lid or the tub for installation. The features may be required to return to a first position after temporary deformation to a second position to allow for insertion of a feature. The features may not return to the first position after installation but may be positioned in a third in-use position.
[0108] How the hinge stays engaged
[0109] In implementations, the hinge features on the lid may be formed with protuberances that prevent separation of the parts after assembly. The features may resist or promote insertion through a slit, slot, hole, gap, or other feature. The hinge assembly may require external tooling or supporting structures during assembly, or be assembled with no external tooling, actions or supports.
[0110] How the hinge axis works and / or moves
[0111] In implementations, the hinge may allow movement of the lid part relative to the tub part. The lid may rotate about an axial location. The rotation axis may be loosely defined, allowing some transverse translation of the lid simultaneously, before, or after the rotation of the lid about the axis. The rotation axis may be tightly constrained, with little translation allowed during rotation. The rotation may require deformation of the tub part or the lid part through partof the rotation. The rotation may be possible without any further deformation of the lid or tub features. The hinge mechanism may include a momentary interference between some elements of the lid or tub to create friction or restrict free rotation through a portion of the rotation angle. This may keep the lid in an open position (at an angle of 70, 80, 90, 100, 110, 120 deg from the closed position). The interference may be created by features integral to the hinge mechanism or remote to the hinge location. That is, the interference may be created between the lid and the tub in a location separated from the hinge location.
[0112] Why molded fiber
[0113] In implementations, some manufacturing processes and materials can produce unique and useful features. Wet fiber thermoforming, for example type III thermoforming, afterpress fiber molding, dry fiber molding etc., can create features with compound curvature and fine details in a part with good mechanical properties. The materials typically used in this technology are inherently sustainable (wood and non-wood fibers, including virgin and post-consumer and post-industrial recycled materials). The fine details and complex surface topology lend and / or provide details and features that may not require additional added materials or processes. This may result in a packaging component that is suitable for recycling. A primary goal of a packaging container is to protect a product or material through its entire supply chain, right to the end-consumer use and eventual disposal of the packaging materials. A secondary goal may be to provide users with a sustainable packaging option. A sustainable packaging solution may be a solution that uses less material (source reduction), uses recycled materials in manufacture, is reusable once its original product is exhausted, or is easily recycled in some or all regions of the market area. Molded fiber technology affords packaging components with a high degree of sustainability and usability, with a reduction in resource extraction intensity.
[0114] In certain types of features, a higher degree of durability or mechanical properties may be desired. In implementations, polymers can be over molded onto molded fiber parts. In implementations, components of other materials can be connected to molded fiber parts to provide different characteristics, such as increase strength, wear resistance, flexibility, barrier properties, ...., or precision mechanical fit for improved relative motion, secure locking etc. Examples could include ribs, snaps, bearings, axles, grommets, clips, etc.
[0115] It is important for dissimilar materials to be considered in end-of-life scenarios for packaging components. In some recycling facilities, a ratio of materials can be considered. In apaper-recycling facility, a ratio of 5% contamination may be acceptable for viable reclamation of the paper materials. In such implementations, a second material can be included with a paper component, that will be seen as a contaminant to the paper recycling process. If the ratio of the weight of the second material to the main material is less than 5:100, then a second functional material could be used without preventing full recycling of the packaging component. In this way, an over molded grommet, hinge, clip, snap, bump, groove ... etc. element can be made of a second material as shown in the figures. A molded fiber packaging component made from wood or non- wood fibers, can be over molded with a biopolymer, which can provide functional benefits of the over molded biopolymer while also providing sustainability benefits of reduction of fossil fuel materials at source, such as conventional petrochemical polymers. A second material from the families of metals (aluminum, steels, brass, etc. etc.) could also be used at low weight ratios while allowing conventional recycling.
[0116] In a non-limiting illustration, an example ratio can be a molded fiber part of 65g of wood fiber which can include a crimped grommet of 1g of aluminum or steel to improve the hinge properties. The resulting ratio of 1.5% steel to 98.5% wood fiber would be widely accepted in paper recycling facilities. Similar ratios can be achieved for plastic, biopolymer, rubber, silicone, or other materials as contaminants. Note that the ratio of contaminants to target materials accepted in waste recovery and recycling facilities varies widely around the world. It can vary between less than 5% in some European countries to less than 20% in some North American countries. After a package is used and before it is placed in a consumer’s recycling bin for collection, dissimilar materials can be separated. Examples of this include, but are not limited to, peeling a film off of a laminated paper component or removing labels off of a steel can or glass bottle. Historically, contamination levels in recycling material streams need to be low, so it was important for consumers to remove labels. Recycling and material reclamation technologies have improved significantly, and requirements for removal of labels from packages is reduced.
[0117] However, some new categories of packaging has reached widespread use in recent years. Some examples include paper materials with barrier materials applied as coatings or as laminated films. Depending on the material ratios, this barrier material may be considered contamination in the recycling facility, and preferentially be separated from the main material type. Some consumers may participate in separation of dissimilar materials before placing packaging components in recycling bins for disposal, however, the rate of material separation atsource (by end consumers before relinquishing to waste recovery services) is generally low, even in jurisdictions with generally high recycling rates. It can be important to overall efficacy of material reclamation programs to reduce the requirement for consumer participation in separation of materials.
[0118] Child resistance
[0119] Containers for holding dosed or granular materials may contain more than one dose of the enclosed product. The closure system may require an ability to be engaged more than one time. In some cases, lids and closure systems may need to perform effectively through 1, 5, 10, 50, 100, 200, 500, 1000, 1500, and / or more cycles of opening, closing, locking and unlocking. In some embodiments, a package may require performance characteristics that inhibit use by children. Child resistance in packaging is a common requirement when the product inside the packaging can be dangerous to consume - either at an increased dosage, or for products that are not intended to be taken internally. In cases where product formats have desirable characteristics to young children, child resistant packaging may be required. An example of this type of product could be laundry detergent tabs that are made in bright colors with various shapes that look like candy.
[0120] There are different levels of child resistance achievable through mechanical design and material properties in packaging and closure systems. In implementations, a molded fiber container can have a first latch on a corner of the lid and a second latch on a second comer of the lid. This can satisfy a requirement for multiple simultaneous opposing actions. In implementations, a molded fiber container can have a single latch in a single location. This can satisfy a lower child resistance requirement. In implementations, a molded fiber container may have no latch mechanisms and rely only on friction or an adhesive label to stay closed.
[0121] Tamper Evidence
[0122] It may be necessary to provide a secure closure system for retail environments, ecommerce shipping, or wholesale and warehousing operations. Often product safety can be assured to end customers by including a feature on the package that prevents opening of the container without a clear visual indication that the container was opened. It is common to apply stickers or labels onto a closed package that would prevent the package from being opened. Commonly, tamper-evident labels may include special inks, materials, or graphic treatments that increase the visual indication of tampering. Other methods may include integrally-moldedfeatures. This is common in injection-molded plastic containers and closure systems. However, in sustainable packages, there is also a need for effective tamper-evident systems.
[0123] In some implementations, a tamper-evident feature also provides improvement to the mechanical properties of the closure system. In some implementations of the molded fiber container, an integrally-molded tab on the lid may be situated so it can be attached to the container with adhesive. The lid cannot be removed unless the tab is tom away from the lid, or the adhesive is separated. A properly-applied adhesive material will pull fibers from the surrounding materials when it is pulled away, which provides a visual indication that it was pulled away. In other implementations, a separate adhesive-backed label may be used as a tamper-evident indicator. In some embodiments, the adhesive may be pressure-sensitive. Some tamper-evident tabs may include perforated areas that are intended to be torn in order to open the container. There is very little force required to tear the perforation so it doesn’t provide a mechanical barrier to opening the container, but does provide obvious visual indication that it was tom. Those skilled in the ait can contemplate other methods for providing tamper-evident features in closure systems. This is shown, for example, in FIGS. 68-73.
[0124] Security of closing and performance in drop testing and shipping. In some cases, a closed lid may come open unintentionally, because of a dynamic impact or shock load, such as a fall from a countertop or vibration from a shipping environment. In such cases, multiple locking mechanisms may provide better retention for the closure as shown in FIG. 1 for a multiple-latch lid and in FIG. 67 for a single-latch lid.
[0125] FIG. 1 shows a front perspective view of an assembled product, i.e., a molded fiber container 1005. The molded fiber container 1005 can include a tub 1000 and a lid 1010 which can be connected via a pair of or two latches 1020 to secure the lid 1010 in a closed position and hinges 1030 (e.g., a pair of the hinges 1030) to provide rotation axis to open the lid 1010 relative to the tub 1000. The tub 1000 and the lid 1010 are molded fiber components of the molded fiber container 1005.
[0126] FIG. 2 shows a rear perspective view of the molded fiber container 1005 with the hinges 1030 that connect the lid 1010 to the tub 1000.
[0127] FIG. 3 shows a side orthographic view of the molded fiber container 1005.
[0128] FIG.4 shows a front orthographic view of the molded fiber container 1005 with the lid 1010 latched via the two latches 1020 on the tub 1000, i.e., in a closed position.
[0129] FIG. 5 shows a rear orthographic view of the molded fiber container 1005 with the lid 1010 in a closed position relative to the tub 1000. The hinges 1030 arc shown.
[0130] FIG. 6 shows a rear perspective view of the lid 1010 with an untrimmed lid hinge area 1012 on one of the hinges 1030. FIG. 7 shows rear perspective view of a trimmed lid hinge area 1014. FIG. 8 shows a rear perspective view of a trimmed and folded lid hinge area 1016. Shown are molded features, where trimming will transform the parts into useful features and / or components. The untrimmed lid hinge area 1012 is the location where transforms are done to create features and / or components such as folding lines 1032 and hinge tabs 1034 of the hinges 1030. The hinges 1030 can be created by coining or other compression methods. In the trimmed and folded lid hinge area 1016, the hinge tabs 1034 is folded along at least one of the folding lines 1032 to an in-use position (i.e., a post-molding transform). The hinge tabs 1034 on the lid 1010 are transformed from a first position (unfolded) to a second position (folded). In implementations, the first position can be a molded position. The hinge tabs 1034 have protrusions 1035.
[0131] FIG. 9 shows a front perspective view of an untrimmed lid latch area 1013 of the lid 1010. FIG. 10 shows a front perspective view of a trimmed lid latch area 1015 of the lid 1010. In implementations, the lid 1010 can be molded with surface topology suitable for specific functions. In implementations, the surface topology requires a trimming or other transformation operation to become effective. In implementations, front corners of the lid 1010 has features that can be trimmed in a direction with a punching operation to create holes 1022 of the two latches 1020 in the lid 1010 to interact with a lug, protrusion, or tab on the tub 1000 to form the two latches 1020. In implementations, a molded fiber part (such as the lid 1010 or the tub 1000) can be molded with features designed to perform a function only after transformation by an operation that changes the topology or geometry of the part, feature, features, or surrounding geometry. In implementations, surfaces of a molded fiber part can be defined in a generally perpendicular angle to a subsequent direction of tooling movement, for example, a die cutting operation. The molded fiber part may be molded with extra material at the perimeter of the pail. The intended final overall dimension of the molded fiber part may be smaller than the first molded overall dimension. A first molded state and a second trimmed state of the molded fiber part may differ in geometry, weight, topology, or a combination. The molded fiber part may be molded with features specifically optimized for molding. The second trimmed state of the molded fiber partmay require some material areas to be removed or modified to enable some functions. The second trimmed state function could be part of an assembly or operation as a hinge or latch, such as a lid on a tub.
[0132] FIG. 11 shows a side orthogonal view of the lid 1010 with the trimmed lid hinge area 1014 and the hinge tabs 1034. A molded fiber part could include features intended to perform a function only after certain transformations from a first molded state to a second trimmed and a third assembled state. In implementations, there are molded-fiber protrusions on a first cap part, i.e., the hinge tabs 1034 on the lid 1010, that interfere with associated slots or tabs on a second container part, i.e., the tub 1000 as shown in FIGS. 15 and 17-28. The protrusions may be formed with a draft angle suitable for molded fiber technology in a first molded state. The draft angles and protrusion direction may not be suitable for the molded fiber lid’s second position. Therefore, it can be important to consider both the first molded state and the second trimmed and in-use state when designing a molded fiber part. For example, the bumps that go up / down - when they are folded - they keep the lid connected to the tub 1000 at the hinge area.
[0133] FIG. 12 shows top orthogonal view of the lid 1010 in an untrimmed fiber molded state. There are molded features that do not work until they are trimmed and folded as described herein. FIG. 13 shows a top orthogonal view of the lid 1010 in a trimmed fibbed molded state. As such, the size is different. There are trimmed features (edges etc.) that work with the molded features. A trimmed state defines a second trimmed state of a molded fiber part with a first molded state.
[0134] FIG. 14 shows a top orthogonal view of the tub 1000 in an untrimmed molded state. The tub 1000 is molded with features intended to function only after they are transformed through trimming, bending, folding etc. as described herein. The tub 1000 includes a base 1040, a sidewall 1050 projecting from the base 1040, and a lip 1060 extending from the sidewall 1050. The lip 1060 can have latch areas 1070 and hinge areas 1080.
[0135] FIG. 15 shows a top orthogonal view of the tub 1000 in a trimmed molded state. The trimmed molded state of the tub 1000 is shown with features, such as protrusions or lugs 1072 in the latch areas 1070 and slots 1082 and Haps 1084 in the hinge areas 1080, which are produced by a trimming operation, for example. The perimeter or lip 1060 of the untrimmed molded fiber part or tub 1000 (in untrimmed molded state) is a different size than that of the perimeter or lip 1060 of the trimmed molded state of the tub 1000. The molded fiber process produces parts withhigh dimensional variability at the edges. There are fibres and uneven shape of the edge produced by the molded fiber technology process. Trimming produces an even edge that may be precisely detailed for specific functional benefit. Features that can be produced in the trimming process may include smooth edges, slots, slits, holes, tabs, notches, etc. as described herein. Some combination of slots and holes may produce features suitable for engagement with tabs on a second molded fiber part or part made of other materials or combination of materials. That is, the lugs 1072 of the tub 1000 can engage the holes 1022 of the lid 1010 and the slots 1082, recesses, or holes and the flaps 1084 of the tub 1000 can engage with the hinge tabs 1034 of the lid 1010.
[0136] FIG. 16 shows a perspective detail view of the hinge areas 1080 of the tub 1000 in the untimed molded state. An area of the tub 1000, i.e., the hinge areas 1080 can be molded with features that are intended to become, through various transformations, bending areas, slots, slits, holes, etc. Shown here is the untrimmed molded state of the hinge areas 1080. Protuberances, i.e., hinge tabs 1034, from the lid 1010 can be paired with recesses (as shown in FIG. 18) in an opposite surface, i.e., the hinge areas 1080, to create focused areas of folding. Shown also are supporting structures 1088 to make the hinge areas 1080 stronger.
[0137] FIG. 17 shows a perspective detail of the hinge areas 1080 of the tub 1000 in a trimmed molded state. That is, a trimmed molded state of the hinge areas 1080 are shown. The trimmed molded state of the hinge areas 1080 now shows the flaps 1084 and the recesses or holes 1086 that can be engaged by the hinge tabs 1034. The flaps 1084 can include folding or bending areas 1085. The flaps 1084 can maintain the hinge tabs 1034 such that the lid 1010 can be rotated between open and closed positions relative to the tub 1000.
[0138] FIG. 18 shows a perspective detail view of the tub 1000 in the trimmed molded state with flaps 1084 bent into in-use position. That is, the flaps 1084 are moved from a first trimmed molded state to a second deployed position. This deployment can result from an assembly step where the hinge tabs 1034 on the lid 1010 can be forced into assembled position with the tub 1000.
[0139] FIG. 19 shows a perspective view of the tub 1000 and the lid 1010 in trimmed molded states and ready for assembly into the molded fiber container 1005. FIG. 20 is a detailed view of FIG. 19. FIG. 21 is a line view (not shaded) of FIG. 20. The hinge tabs 1034 on the lid 1010 are positioned, prior to assembly, to the flaps 1084 and the holes 1086 on the tub 1000, andthe holes 1022 are aligned with the lugs 1072.
[0140] FIG. 22 shows the tub 1000 and the lid 1010 of FIG. 19 in physical contact. FIG. 23 is a line view of FIG. 22. The lid 1010 is in a closed position and forms a seal around the perimeter of the tub 1000.
[0141] FIG. 24 shows a perspective detail view of the molded fiber container 1005 in an assembled mode. FIG. 25 is a line view of FIG. 24. FIG. 26 is a detailed view of FIG. 24. FIG. 27 is a bottom detailed view of FIG. 24. FIG. 28 is a bottom detailed perspective view of FIG. 24. The flaps 1084 are folded down into the second in-use position. The protrusions 1035 are engaged with the flaps 1084 to prevent disengagement of the hinge tabs 1034. That is, the lid 1010 is retained to the tub 1000. The hinge tabs 1034 are retained to the tub 1000, allowing the lid 1010 to rotate from a first closed position to a second open position.
[0142] FIGS. 29-36 show multiple views of using an assembly tool 29000 (e.g., a hinge assembly tool) to connect the tub 1000 and the lid 1010 to form the molded fiber container 1005 as described herein. FIG. 29 is a cross-sectional view of the assembly tool 29000 in a ready position to push the hinge tabs 1034 through the flaps 1084 and the holes 1086. FIG. 30 is a detailed perspective view of FIG. 29. The hinge tabs 1034 are ready to be displaced from a first position to a second position. FIG. 31 is a detailed perspective view. The assembly tool 29000 can include support members 29100 to stabilize and immobilize the stationary portions of the hinge tabs 1034 of the lid 1010 that are on the tub 1000. This allows the flaps 1084 to move from a first position to a second position, with the region of deformation (bending) of the flaps 1084 part in a focused and predictable location.
[0143] FIG. 32 is a cross-sectional view that shows the assembly tool 29000 push the hinge tabs 1034 from a first position to a second engaged position. FIG. 33 is a detailed perspective view of FIG. 32. FIG. 34 is a detailed perspective view of FIG. 32. The assembly tool 29000 moves from a first position to a second position, where the second position causes the hinge tabs 1034 on the lid 1010 to displace the flaps 1084 on the tub 1000 from a first position to a second position. In the second position, the flaps 1084 retain the hinge tabs 1034 on the lid 1010 in a working and retained position.
[0144] FIG. 35 is a perspective which shows the assembly tool 29000 moving back to start position after completing assembly. That is, the assembly tool 29000 has completed the assembly and rotated through. The assembly tool 29000 is ready to return to start position.
[0145] FIG. 36 is a perspective which shows the assembly tool 29000 ready to operate again after performing the assembly step. The assembly tool has completed the assembly and rotated around to a ready position for the next tub and lid.
[0146] FIG. 37 is a perspective detailed view of a tub 37000 in a molded state. FIG. 38 is a cross-sectional view of FIG.38. The tub 37000 is similar to the tub 1000 except as described herein. The tub 37000 includes an opening 37100. In implementations, the opening 37100 can be used for installation of a grommet or overmolding of a protective material (collectively a “protective component 37200”). The protective component 37200 can be made from metal, plastic, paper, etc. The opening 37100 can formed, trimmed, punched, or cut into a portion of the tub 37000. The opening 37100 is then ready to receive the protective component 37200.
[0147] FIG. 39 is a cross-sectional detailed view of pre- attachment of the protective component 37200 to the opening 37100. FIG. 41 is a perspective view of FIG. 39. FIG. 43 is a perspective view of FIG. 39. In implementations, the protective component 37200 is a multiplepart snap ring or grommet, i.e., a first snap ring component 37210 and a second snap ring component 37220. The protective component 37200 can be used to provide durability in a high- wear area of an operating hinge. The protective component 37200, i.e., the multiple-part snap ring or grommet, can be made of two parts, i.e., the first snap ring component 37210 and the second snap ring component 37220, that snap together. FIG. 39 shows the first snap ring component 37210 and the second snap ring component 37220 in position to be assembled.
[0148] FIG. 40 is a cross-sectional view of the first snap ring component 37210 and the second snap ring component 37220 after assembly to form the protective component 37200, i.e., the multiple-part snap ring or grommet. FIG. 42 is a perspective view of FIG. 40.
[0149] FIG. 44 is a cross-sectional view of a tub 44000 pre-attachment of a protective component 44200 to an opening 44100 in the tub 44000. In implementations, the protective component 44200 is a protective ring made of metal or other material which can be crimped or formed into position in the punched, trimmed, or formed opening 44100 in the tub 44000 to make a durable pivot area in tub 44000. The protective component 44200 can protect a through- hole, i.e., the opening 44100, in the tub 44000.
[0150] FIG. 45 is a detailed perspective view of the tub 37000 after attachment of the protective component 37200 and after attachment of a lid 45000 via hinge tabs 45100. FIG. 46 is a detailed cross-sectional view of FIG. 45. The hinge tabs 45100 have protrusions 45110, whichcan also be referred to as locking bars. The protrusions 45110 are overmolded onto the hinge tabs 45100, which arc a fiber molded component. That is, the hinge tabs 45100 have an ovcrmoldcd lock feature, i.e., the protrusions 45110, which maintain connection of the lid 45000 to the tub 37000 as the lid 45000 is opened and closed relative to the tub 37000. The protrusions 45110 can provide a retention force to enable the lid 45000 to pivot during normal operation, but not withdraw from the protective component 37200, e.g., a grommet, in certain situations.
[0151] FIG. 47 is a perspective of the molded fiber container 1005 with the lid 1010 partially open with respect to the tub 1000. FIG. 48 is a cross-sectional detailed view of FIG. 47. FIG. 49 is a cross-sectional orthographic detailed view of FIG. 47. FIG. 50 is a perspective detailed view of FIG. 47. FIG. 51 is a lower perspective detailed view of FIG. 47. The hinge tabs 1034 and protrusions 1035 of the lid 1010 are locked or retained by the flaps 1084 of the tub 1000.

FIG. 56 is a perspective rear view of FIG. 52 with the lid 52200 partially open. The molded fiber container 52000 is similar to the molded fiber container 1005 except as described herein. The snap type hinge 52100 includes a lid tab 52210 which is designed to be pressed through a restricted tab area 52310 in the tub 52300, resulting in retaining the lid 52200 with a movable hinge. The lid tab 52210 and restricted tab area 52310 interaction allows for pivoting movement of the lid 52200 relative to the tub 52300. The lid pivot point is not restricted to a single axis of rotation.
[0153] FIG. 57 shows side perspective view of the molded fiber container 52000 preattachment of the lid 52200 and the tub 52300 via the snap type hinge 52100. FIG. 58 is a side cross-sectional view of FIG. 57. FIG. 59 is a rear perspective view of FIG. 57. FIG. 60 is a detailed rear perspective view of FIG. 57. FIG. 61 is a line view of FIG. 60. FIG. 62 is a line view of FIG. 60. As shown, the lid tab 52210 is positioned in alignment with the restricted tab area 52310.
[0154] FIG. 63A is a diagram for insertion of the lid 52200 onto the tub 52300. A lid insertion tool 63000 can be used to insert the lid tab 52210 through the restricted tab area 52310 to complete the snap type hinge 52100. The lid insertion tool 63000 can include a support platform 63100 for supporting the tub 52300 during the insertion process.
[0155] FIG. 63B is a hinge arrangement for a molded fiber container 63200. The molded fiber container 63200 is similar to the molded fiber container 1005 except as described herein. The molded fiber container 63200 includes a lid 63210 and a tub 63220. The lid 63210 includes a lid tab 63212, which in turn includes a protrusion 63214. The tub 63220 includes a restricted tab area 63222. An insertion tool, such as the lid insertion tool 63000 can be used to insert the lid tab 63212 through the restricted tab area 63222 such that the protrusion 63214 maintains a connection between the lid 63210 and the tub 63220 as the lid 63210 is opened and closed relative to the tub 63220.
[0156] FIG. 63C is a hinge arrangement for a molded fiber container 63202. The molded fiber container 63202 may be similar to the molded fiber container 1005 except as described herein. The molded fiber container 63202 may include a lid 63216 and a tub 63218. The lid 63216 may include a lid tab 63240, which may extend into an opening 63242 defined by the tub 63218. The lid tab 63240 may maintain engagement such that the lid 63216 may move based upon movement and / or bending of the lid tab 63240. As shown, the lid tab 63240 may extend substantially orthogonal to the lid 63216 and may bend or otherwise flex with respect to the lid 63216 to facilitate opening and / or closing of the lid 63216 with respect to the tub 63218.
[0157] FIG. 63D is a hinge arrangement for a molded fiber container 63204. The molded fiber container 63204 may be similar to the molded fiber container 1005 except as described herein. The molded fiber container 63204 may include a lid 63224 and a tub 63226. The lid 63224 may include one or more lid tabs, such as the lid tabs 63228. The lid tabs 63228 may interconnect or otherwise engage the tub 63226. For example, one of the lid tabs 63228 may be configured to bend when coupled or otherwise engaged to a hinge region 63230 of the tub 63218.
[0158] FIG. 63E is a hinge arrangement for a molded fiber container. The molded fiber container may be similar to the molded fiber container 1005 except as described herein. As shown in FIG. 63E, the hinge arrangement may include a hinge portion 63232. The hinge portion 63232 may be integrally formed with, or otherwise connected to, the tub and / or the lid to facilitate opening and / or closing of the lid with respect to the tub. The hinge portion 63232 may be flexible (e.g., bendable). The hinge portion 63232 may also define an opening 63234 therein, which may be configured to receive a portion of the tub or the lid to thereby connect the tub to the lid.
[0159] FIGS. 64A-F show a hinge arrangement for a molded fiber container. The molded fiber container is similar to the molded fiber container 1005 except as described herein. The molded fiber container includes a lid 64100 and a tub 64200. The lid 64100 includes hinge areas 64110. The tub 64200 includes hinge tabs 64210. The hinge tabs 64210 are molded parts. The hinge tabs 64210 are trimmed and folded for assembly with the lid 64100. The hinge tabs 64210 include wide portions 64212. The lid 64100 is placed on the tub 64200 and the hinge tabs 64210 fit through the hinge areas 64110. The wide portions 64212 maintain contact between the lid 64100 and the tub 64200 as the lid 64100 is opened and closed relative to the tub 64200.
[0160] FIG. 65 illustrates various configurations of molded hinges 65100. The molded hinges 65100 may be configured to couple a container to a lid. For example, the molded hinges 65100 may be configured to connect a lid, such as the lid 64100 shown in FIGS. 64A-F to a molded fiber container, such as the molded fiber container 1005. As such, the molded hinges 65100 may be configured to move the lid from a closed position in which the lid enclosed (e.g., covers) an opening defined by the container, to an open position, in which the lid is spaced apart from the opening of the container to permit access to the container through the opening.
[0161] As shown in FIG. 65, the molded hinges 65100 may have various molded members or components that may facilitate movement of the lid with respect to the container, or vice versa. For example, the molded hinges 65100 may be a single, integrated component that forms the molded hinges 65100 (e.g., a monolithically formed member, which may form the molded hinges 65100 in their entirety). Alternatively, or additionally, the molded hinges 65100 may be formed from one or more interconnected components. For example, the molded hinges 65100 may include a first molded component and a second molded component. The first molded component may be coupled to the second molded component, such as via a mechanical connector (e.g., fastener, hook, latch, pin, clip, etc.) to form the molded hinges 65100. In some configurations, the first molded component may be nested with the second molded component, such as to form a knuckle or joint of the molded hinges 65100.
[0162] The molded hinges 65100 may be or may include a bendable region 65200. The bendable region 65200 may facilitate bending (e.g., hinging) of one portion of the molded hinges 65100 with respect to another portion of the molded hinges 65100. That is, the bendable region 65200 may define a pivot (e.g., a pivot joint) of the molded hinges 65100 to facilitate movement of the molded hinges 65100, thereby also facilitating movement of the lid relative to thecontainer, or vice versa. In some configurations, the bendable region 65200 may be a localized decrease in thickness of the material of the molded hinges 65100, may include one or more notches, grooves, scoring, or other features that may aid with promoting bending at the bendable region 65200, or a combination thereof. Furthermore, such bending at the bendable region 65200 may be done before, during, or after assembly. For example, the molded hinges 65100 may be molded in a first, open position and deformed (e.g., bent at the bendable region 65200) during assembly when coupled to the lid and / or the container, whereby deformation may move the molded hinges 65100 into a second, interfering position (e.g., the first portion and the second portion of the molded hinges 65100 may interfere with one another).
[0163] The molded hinges 65100 may also include one or more additional features. For example, the molded hinges 65100 may include a stopper 65300, which may be configured to engage a portion of the container and / or the lid in the open and / or close position. For example, the stopper 65300 may be configured to abut the container and / or a portion of the molded hinges 65100 when the molded hinges 65100 are coupled to the container and / or the lid. For example, as shown in FIG. 65, the stopper 65300 may be inserted into an opening 65400 defined by the lid by bending one of the molded hinges 65100 at the bendable region 65200 such that the bent portion of the molded hinge is positioned within the opening 65400. When inserted into the opening 65400, the stopper 65300 may abut a portion of the molded hinge to maintain engagement between the molded hinge and the lid.
[0164] FIG. 66 illustrates a cross-sectional view of another example of a molded hinge 66100. The molded hinge 66100 may be similar to the molded hinges 65100 shown in FIG. 65. For example, the molded hinge 66100 may include a first portion 66200 coupled to a second portion 66300 via a bendable region 66400 therebetween.
