Description
TECHNOLOGICAL FIELD

An example embodiment relates generally to foldable containers.


BACKGROUND

Disposable cups are widely used throughout the food service industry from fast food service restaurants to school cafeterias. Such cups are made of paper or plastic material configured to contain either hot or cold beverages. Traditional disposable cups are configured to accept separate plastic lids that conform to the top of the cup by snapping in place over a rolled edge. The lids may be configured with a hole to drink from directly, such as coffee cup lids, or to accept a separate straw, for example soda fountain cup lids. Food service facilities are often equipped with individual fixtures to house disposable cups, lids, and straws individually in order to be dispensed to an employee or an end user for assembly. Additionally, food service facilities utilize conventional non-water tight paper containers for food products. Conventional plastic containers, or plastic lids with paper containers, are utilized for containing food products prone to leakage.


SUMMARY

Embodiments of the present disclosure are directed to a cup with an integrated folding lid. The inventors have identified problems associated with traditional disposable cups and propose an integrated lid and cup to overcome these identified problems. Traditional disposable cups require at least a separate plastic lid which snaps over the opening of the traditional cup by holding onto a rolled edge of the cup with tabs configured around a mating surface on the lid. These tabs may not fit the cup properly creating a loose lid to cup interface leading to leaking or spillage. Another issue associated with traditional disposable cup lids is that they can split or break if a user attempts to remove the lid. For example, if a user removes a lid to refill the cup, or add ice, then the lid may tear, bend, or otherwise break requiring a new lid. It will be appreciated, in light of the present disclosure, that such traditional plastic disposable lids unnecessarily add to increased garbage production and waste. Moreover, in instances that a disposable cup contains a hot beverage a loose or broken lid may lead to injury, for example, burns on the skin, when a user attempts to drink from the lid. Traditional disposable cups, lids, and straws also place additional logistical burdens on the food service industry and suppliers thereof. For example, traditional disposable cups, lids, and straws are often produced in separate facilities and are required to ship individually to a supply distributor or a restaurant directly. Additionally, the restaurants must allocate additional employee hours to inventory and track cup, lid, and straw quantities individually for each cup size offered.


The same aforementioned limitations are also associated with conventional take-out food containers which suffer from further limitations. For example, conventional take-out food containers are either of a folding paper type, which are not water tight due to a folded bottom, or of a cup and lid combination (e.g., paper and/or plastic soup or beverage cup and lid combinations). Further, conventional take-out food containers of the folding paper type (e.g., Chinese food takeout containers, etc.) are often restricted to square or rectangular cross-sectional geometries only and are not suited for cup holders, or the like (e.g., insulation sleeves, koozies, etc.). Additionally, such conventional folding paper type containers cannot be assembled and stacked for easy accessibility by a consumer. For example, traditional soda fountain cups are often stacked (e.g., a series of cups are inserted over each other) next to a soda fountain for a consumer, or food service employee, to easily access a cup and fill it at the soda fountain. Conventional folding paper type containers are prone to folding in on themselves when unfilled and therefore cannot be easily stacked over each other without binding and tearing when a consumer, or food service employee, goes to separate the conventional folding paper type containers. Conventional folding paper type containers therefore place an additional time and manpower burden on food service facilities because the Conventional folding paper type containers have to be assembled on a per order basis. Further, in instances where a food order contains multiple food types a combination of conventional folding paper type and conventional cup and lid containers must be used (e.g., an order containing rice and soup). It will be appreciated, in light of the present disclosure, that a food service facility must commit additional resources to store, assemble, track, and reorder a plurality of conventional container types.


The present disclosure proposes to solve at least the aforementioned problems associated with conventional folding paper type containers, and conventional cup and lid containers, through the provision of a cup with an integrated lid. The integrated lid may be configured with a portion of the lid configured to consume liquid therethrough further removing the need for a separate straw in some embodiments.


An example embodiment comprises an enhanced integrated cup with an integrated lid that is assembled by folding a continuous piece of material, such as paper, cut into a pre-configured shape (i.e. a blank). In such embodiments, the enhanced integrated cup comprises one or more of a base, a sidewall, an integrated lid section, a tab and slit, a fold line, or an adhesive. In some embodiments, the base may be a separate piece of material attached to a bottom portion of the sidewall, for example, by way of an adhesive (e.g., epoxy, etc.). In some embodiments, the base may comprise the same material as the sidewall and integrated lid components of the enhanced integrated cup. In some embodiments, the cup with the integrated lid may be at least partially assembled before reaching an end user (i.e., a consumer). For example, the cup may be shipped to a restaurant with a base and sidewall folded together and attached by way of an adhesive in order to maintain a substantially recognizable cup shape with an open top. In such embodiments, integrated lid sections may extend upward from at least an upper portion of the sidewall and at the transition region between the sidewall and the integrated lid sections one or more fold lines are configured. The one or more fold lines are configured to provide for the folding of the integrated lid sections over the opening of the cup to substantially form a covering (i.e., lid) over the opening of the cup without the need for a separate lid component. In some embodiments, at least a portion of the integrated lid may form a hole configured for drinking. In such embodiments, at least a portion of the integrated lid may protrude to define a spout configured to receive a straw, to drink from directly, or to pour out contents of the cup.


In some embodiments, the continuous piece of material used to make the enhanced integrated cup blank may comprise one or more materials including, without limitations, paper, plastic, foams, fabrics, the like, or combinations thereof. In some embodiments, the one or more materials may be at least partially treated with sealants to block the absorption of fluid into the material and thereby prevent leakage from the enhanced integrated cup. In some embodiments, only the interior of the cup's side wall and base may be treated with sealant. In other embodiments, all exposed surfaces of the enhanced integrated cup may be treated with sealant. In yet other embodiments, no sealant may be utilized. Sealants may include, without limitation, one or more of a natural coating, a synthetic coating, a plastic-free coating, polylactic acid (PLA), wax (e.g., paraffin wax, beeswax, etc.), resin, epoxy, petroleum-based coating (e.g., polyethylene, etc.), the like, or combinations thereof. In some embodiments, it will be appreciated that a plastic free coating may be applied such that the drink is allowed to be fully contained without seepage for up to 6 hours. In some embodiments, a paper material used to produce the enhanced integrated cup blanks may comprise a single sheet of paper, multiple sheets of paper overlaid and attached to each other (e.g., by way of adhesives, a lamination process, etc.), one or more sheets of carboard, the like, or combinations thereof. For example, in an instance the enhanced integrated cup is intended for cold drink products (e.g., iced tea) the material may comprise a single sheet of paper coated with PLA to prevent liquid absorption into the paper material. In an alternative example instance, wherein the enhanced integrated cup is intended for hot drink products (e.g., coffee), the material may comprise cardboard treated with a wax coating. In some embodiments, cardboard materials may be configured with one or more channels between at least two surfaces and the space within the channels may be configured to insulate the sidewalls of the enhanced integrated cup. It will be appreciated, in light of the present disclosure, that wax and PLA based sealants may be utilized to improve the biodegradability of the enhanced integrated cup.


In other embodiments, a plastic material used to produce the enhanced integrated cup blanks may comprise one or more sheets of a thermoplastic, a thermoset, polyethylene terephthalate (PETE), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), polycarbonate (PC), silicone, polylactic acid (PLA), the like, or combinations thereof. In some embodiments, the enhanced integrated cup may be repeatedly washed and reused by a consumer. For example, the enhanced integrated cup may be produced by means of injection molding utilizing a silicone material, or the like. In such example embodiments, the integrated lid of the enhanced integrated cup may be repeatedly opened and closed without substantial deterioration accumulating along one or more fold lines. It will be appreciated, in light of the present disclosure, that in at least such plastic embodiments the one or more fold lines are configured to function as living hinges configured for multiple reuses. In some embodiments, plastic materials may be configured with one or more channels between at least two surfaces and the space within the channels may be configured to insulate the sidewalls of the enhanced integrated cup.


It will be appreciated, in light of the present disclosure, that materials may be selected and/or configured based on one or more of their physical characteristics including, without limitation, color, thermal properties, chemical resistance, the like, or combinations thereof. In some embodiments, the thickness of a material may be increased or decreased to proportionally increase or decrease heat transfer therethrough. For example, a material thickness may be increased to insulate the enhanced integrated cup from heat transfer therethrough. In some embodiments, the enhanced integrated cup blank may comprise one or more thicknesses. For example, a sidewall portion of the blank may be configured with a first thickness while an integrated lid section may comprise a second thickness and a base section may comprise a third thickness.


According to an aspect of the present disclosure, there is provided a cup with an integrated folding lid. In embodiments, the cup with the integrated folding lid may comprise a body comprising one or more materials. The body may comprise one or more fold lines that when the body, or a portion thereof, is bent along the one or more fold lines the body may comprise, and/or define, a center portion, a circular bottom portion, a top portion, and/or a plurality of integrated lid sections. In embodiments, the center portion may define a sidewall. The sidewall may be configured as a single continuous surface looped over on itself to define, for example, one or more circular cross-sections. The sidewall may be configured to extend between a first end and a second end, the first end of the sidewall may be attached to the second end of the sidewall, for example, by mechanical and/or chemical means. In embodiments, the circular bottom portion extending from the center portion defining a base.


The circular bottom portion may be configured to extend from the sidewall in a first direction and may attach to a bottom edge. In embodiments, the top portion may define an opening configured to allow access into one or more cavities defined by at least the center portion. In embodiments, the plurality of integrated lid sections extend from the top portion of the cup. The individual sections of the plurality of integrated lid sections may be separated from the top portion by a respective fold line. The plurality of integrated lid sections may comprise at least one integrated lid section that may define at least a tab and at least one integrated lid section defining at least a slit. In embodiments, the slit may be configured to receive, therethrough, the tab. In embodiments, the plurality of integrated lid sections may be configured to interlock at least by way of the tab being received within the slit. The interlocked plurality of integrated lid sections may define a lid cover that may be configured to at least partially cover the opening.


In some embodiments, the sidewall and the base define a water tight retention cavity at least partially enclosed by the body. In some embodiments, the sidewall, the base, and one or more dividers, attached to the sidewall and/or the base, define a plurality of water tight retention cavities at least partially enclosed by the body. In some embodiments, the one or more dividers may be attached to the sidewall and/or the base by way of one or more mechanical and/or chemical means. In some embodiments, mechanical attachment means may comprise one or more of a lap seam, countersunk lap seam, outside lap seam, standing seam, flat lock seam, grooved flat lock seam, lap bottom seam, insert bottom seam, single bottom seam, crimp, the like, or combinations thereof. In some embodiments, chemical attachment means may comprise one or more of a reactive adhesive, a non-reactive adhesive, a natural adhesive, a synthetic adhesive, a polyurethane resin, a thermoset epoxy, a cyanoacrylate, a pressure-sensitive adhesive, the like, or combinations thereof.


In some embodiments, the one or more dividers may comprise the same one or more materials (e.g., paper, cardboard, sealant, etc.) as the body of the cup. In some embodiments, the one or more dividers may comprise a different one or more materials (e.g., paper, cardboard, sealant, etc.) as the body of the cup. For example, the body of the cup may comprise a cardboard material with a wax based sealant coating and the one or more dividers may comprise a single sheet of paper material with a polylactic acid based sealant. In some embodiments, the one or more dividers may divide the water tight retention cavity into a plurality of water tight retention cavities defining a series of concentric circles. In some embodiments, the one or more dividers may divide the water tight retention cavity into a plurality of water tight retention cavities defining a series of polygons (e.g., semicircles, squares, rectangles, half-circles, the like, or combinations thereof).


It will be appreciated, in light of the present disclosure, that the one or more dividers that define a plurality of water tight retention cavities may be used to separate a plurality of contents of the cup. For example, a cup may be divided into two water tight retention cavities, each cavity accessible via at least a respective spout configured to accept at least a straw, and each cavity may be at least partially filled with dissimilar beverages (e.g., cola, ginger ale, water, etc.). For additional example, a first cavity may retain a beverage while a second cavity may retain ice (e.g., in a circular concentric configuration, such that the ice is in an inner cavity while the beverage is in an outer cavity). It will be appreciated, in light of the present disclosure, that by separating the beverage and the ice, the beverage will not become diluted over time as the ice melts providing an improvement over conventional beverage and/or food containers. In some embodiments, the spout may be configured for pouring liquid from the cup. For example, embodiments of the present disclosure may be configured as disposable restaurant silverware such as milk pourers or water pitchers that are replaced for hygiene purposes when a table is cleaned and prepared for the next customer.


In some embodiments, the opening of the top portion is configured to receive at least a liquid substance, and/or a solid substance, therethrough to be retained within the water tight retention cavity. In some embodiments, the opening of the top portion is configured to receive one or more of a beverage, a food product, the like, or combinations, therethrough, to be retained within the water tight retention cavity.


In some embodiments, the interlocked plurality of integrated lid sections define a spout extending from, and extruding through, the lid cover, the spout configured to convey at least the liquid retained in the water tight retention cavity therethrough. In some embodiments, the spout defines a drinking opening and the drinking opening may be configured to receive one or more of a straw, a stirrer, or a utensil (e.g., spoon, fork, etc.). In some embodiments, the spout is positioned at a junction between the interlocked plurality of integrated lid sections and the sidewall. In some embodiments, the spout is positioned to extend perpendicular to a surface defined by the interlocked plurality of integrated lid sections. In some embodiments, the spout is a plurality of spouts that may be configured to access contents retained in one or more water tight retention cavities. In some embodiments, the spout defines one or more of an ovular cross-section, a circular cross-section, a rectangular cross-section, a square cross-section, a frustoconical shape, a conical shape, a cylindrical shape, or a parabolic shape.


In some embodiments, the spout may comprise a conical shape, or similar shape, without an opening. In such embodiments, the spout may further comprise one or more fold lines defining a circumference around one or more surfaces of the spout (e.g., one or more circumferential rings around the outer surface of the spout). In such embodiments, the one or more fold lines defining a circumference around one or more surfaces of the spout may be configured to be bent, folded, and/or torn to form the opening of the spout. For example, a conical shaped spout may be configured with a perforated line midway between the tip and base of the conical shape which may be torn to allow a consumer to drink from the cup. In an instance the perforated line only defines a partial length around a circumference of the conical shape then the tip portion of the conical shaped spout may be folded over to provide access to the spout's opening. It will be appreciated, in light of the present disclosure, that in such embodiments, a cup may be filled, such as by a fast food employee, and then the spout may be opened at a later time by a consumer, thus reducing the risk of intentional or unintentional contamination (e.g., airborne viruses, bacteria, etc.). Indeed, this marks an improvement over conventional cup, lid, and straw systems that require a straw either to be opened and placed in the cup by a fast food employee or to be left sealed and separate from the cup.


In some embodiments, the first end of the sidewall is attached to the second end of the sidewall by way of an adhesive or the like. In some embodiments, the first end of the sidewall is attached to the second end of the sidewall by way of one or more mechanical and/or chemical means. In some embodiments, mechanical attachment means may comprise one or more of a lap seam, countersunk lap seam, outside lap seam, standing seam, flat lock seam, grooved flat lock seam, lap bottom seam, insert bottom seam, single bottom seam, crimp, the like, or combinations thereof. In some embodiments, chemical attachment means may comprise one or more of a reactive adhesive, a non-reactive adhesive, a natural adhesive, a synthetic adhesive, a polyurethane resin, a thermoset epoxy, a cyanoacrylate, a pressure-sensitive adhesive (e.g., tape, etc.), the like, or combinations thereof. In some embodiments, the first end of the sidewall is attached to the second end of the sidewall by overlapping a first portion of the first end of the sidewall over a second portion of the second end of the sidewall. In some embodiments, the first end of the sidewall is attached to the second end of the sidewall by abutting a first edge of the first end of the sidewall against a second edge of the second end of the sidewall. In some embodiments, a strip of one or more materials (e.g., paper, wax sealant, an additional sealant layer, the like, or combinations thereof) may be configured to at least partially cover the seam defined by the attachment of the first end of the sidewall to the second end of the sidewall.


In some embodiments, the base is attached to the bottom edge associated with the third end of the sidewall by way of an adhesive, or the like (e.g., one or more mechanical and/or chemical means). In some embodiments, the base defines one or more of an ovular cross-section, a circular cross-section, a rectangular cross-section, a square cross-section, a frustoconical shape, a conical shape, a cylindrical shape, a parabolic shape, the like, or combinations thereof.


In some embodiments, the one or more fold lines comprise one or more of a perforation line, a creased line, a ridged line, a solid score line, or a dashed score line. In some embodiments, the one or more fold lines may comprise a string of one or more materials (e.g., fabric, paper, aluminum, the like, or combinations thereof) embedded in one or more portions of the cup (e.g., top portion, spout, sidewall, etc.). In such embodiments, the string is configured to be pulled (e.g., by an end extruding out from the one or more portions of the cup) and as the string is pulled it is further configured to at least tear a line, at least partially, through the one or more portions of the cup. For example, the interlocked plurality of integrated lid sections may be torn at least partially open by a string embed in an outer surface of the interlocked plurality of integrated lid sections to form a spout at a junction between the interlocked plurality of integrated lid sections and the sidewall.


In some embodiments, the plurality of integrated lid sections extend upward from the sidewall on a fourth end as one or more continuous extensions of the sidewall.

In some embodiments, the one or more materials are at least partially coated in a sealant. In some embodiments, the sealant comprises one or more of a polylactic acid, wax, resin, the like, or combinations thereof.


In some embodiments, one or more portions of the cup (e.g., the sidewall, the plurality of integrated lid sections, the base, etc.) comprise a thermal insulation. In some embodiments, the thermal insulation comprises a plurality of layers of the one or more materials configured with at least a space therebetween. In some embodiments, the thermal insulation comprises a thermal insulator material comprising one or more of polystyrene insulation, synthetic fibers, natural fibers (e.g., cotton, etc.), cork, corrugated materials (e.g., paper, cardboard, fiberboard, etc.), air, the like, or combinations thereof. In some embodiments, the space between the plurality of layers of the one or more materials is filled with one or more of air, foam, plastic, a vacuum, the like, or combinations thereof. It will be appreciated, in light of the present disclosure, that refrigeration systems for cooling beverages or producing ice are energy intensive and, therefore, by configuring the cup with one or more thermal insulation methods the need for additional ice/cooling is reduced thus reducing overall energy consumption.


In some embodiments, a portion of the cup including, without limitation, one or more of the center portion, the bottom portion, the top portion, or the like may comprise a graphical design print. In some embodiments, the graphical design print comprises one or more of an image, logo, text, numbers, geometric shapes, other aesthetic features (e.g., colors, etc.), the like, or combinations thereof. In some embodiments, the graphical design print comprises one or more of ink, scorched or burnt portions of material (e.g., such as by a laser engraver), a plastic overlay (e.g., vinyl sticker, polylactic acid adhered to an underlying material, etc.), the like, or combinations thereof. In some embodiments, the graphical design print indicates a location of the one or more fold lines along the body. In some embodiments, the graphical design print indicates a direction and/or order to fold the plurality of integrated lid sections. In some embodiments, at least the center portion defines one or more of a frustoconical shape, a conical shape, a cylindrical shape, or a parabolic shape.


In some embodiments, at least the center portion defines one or more diameters perpendicular to at least an outer surface of the sidewall, and the one or more diameters are configured to fit a plurality of cup holders. In some embodiments, at least the center portion is configured with a step-wise profile defined by a series of decreasing outer sidewall diameters. For example, a lower half of the center portion may define a first diameter and an upper half of the center portion may define a second diameter, wherein the first diameter is less than the second diameter. In some embodiments, one or more of the sidewall diameters may be configured to fit in one or more different types of cup holders, cup sleeves, cup koozies, the like, or combinations thereof.


In some embodiments, the spout may be configured with an integrated straw (e.g., a paper or plastic straw mechanically or chemically attached to one or more individual sections of the plurality of integrated lid sections, etc.). In some embodiments, the integrated straw may be configured by folding one or more individual sections of the plurality of integrated lid sections. In some embodiments, the integrated straw may be configured as a portion of the sidewall, the base, and one or more dividers, attached to the sidewall and/or the base. For example, a circular divider attached to the sidewall (e.g., by mechanical or chemical means) may extend from the top portion of the cup (e.g., a predefined distance above the plurality of integrated lid sections through the spout, etc.) down the sidewall to a predefined distance above the base of the cup. It will be appreciated, in light of the present disclosure, that the integrated straw negates the need for a separate supply of individually packaged straws at a food service facility, thus reducing operating costs for the facility while simultaneously reducing environmental impacts from additional straws and straw wrappers (e.g., a plastic straw in a paper or plastic hygiene sleeve).


In some embodiments, one or more folding handles may be configured to attached to the outer surface of the sidewall via mechanical and/or chemical means. For example, a pair of folding integrated handles may be at least partially glued to the exterior of the sidewall and be configured to bend away from the sidewall along one or more fold lines to produce at least one handle for carrying or holding the cup by hand. In some embodiments, the sidewall may be configured with one or more extruded tabs, affixed to the exterior of the sidewall by mechanical and/or chemical means, and configured with one or more slits to receive one or more tabs associated with one or more carrying handles. In such embodiments, the one or more carrying handles may comprise one or more materials and may be attached to the sidewall, or the like (e.g., one or more integrated lid sections of the plurality of integrated lid sections), by a first end of the carry handle and a second end of the carry handle is configured with a tab to interlock with one or more extruded tabs comprising a slit, or the like, (e.g., one or more integrated lid sections of the plurality of integrated lid sections).


In some embodiments, a handle, carrying handle, the like, or combinations thereof may be configured with a pressure sensitive adhesive configured to attach to one or more portions of the cup. For example, a carry handle may be configured with a first piece of pressure sensitive adhesive (e.g., tape, etc.) at a first end and a second piece of pressure sensitive adhesive at a second end and may be attached by a food service employee, or a consumer, to the sidewall or integrated lid of the cup. It will be appreciated, in light of the present disclosure, that some example handles, or the like, configured with pressure sensitive adhesive may be separate from some embodiments of the cup (e.g., an optional peripheral features that may or may not be utilized by a consumer) or may be attached to the cup during initial assembly of the cup. In some embodiments, one or more handles may be integrated into the plurality of integrated lid sections to extend from a first integrated lid section and fold over to define the handle by interlocking with a second integrated lid section (e.g., via a tab and slit configuration, etc.).

FIG. 3 illustrates cutout 302 located between the first integrated lid section 102A, configured with a slit 104, and the second integrated lid section 102B, configured with a tab 106. The plurality of integrated lid sections 102 are depicted in the full open configuration, however, when the plurality of integrated lid sections 102 are in the fully interlocked, or at least partially closed, position then cutout 302 is configured to define an opening, and/or spout, within the integrated lid formed by interlocking the integrated lid sections 102. In some embodiments, cutout 302 may be configured with a straw (not shown) at least attached, therethrough, to a portion of the enhanced integrated cup body. In some embodiments, cutout 302 may be configured with a piece of material (not shown) (e.g., an extension of sidewall 110, integrated lid section 102A, or the like) configured to cover, at least partially, cutout 302. In such embodiments, cutout 302 may be defined, at least partially, by one or more fold lines (not shown) (e.g., a perforated line, etc.) configured around one or more edges of cutout 302. In such embodiments, a user may tear, and/or fold, the piece of material (not shown) along the one or more fold lines (not shown) (e.g., a perforated line, etc.) configured around one or more edges of cutout 302.



FIGS. 4-5 will now be described in terms of relative positioning and as such should not be construed, used, or taken out of the context of FIGS. 4-5 to limit the spirit and scope of embodiments of the present invention or any features described with respect to FIGS. 4-5.

The third integrated lid section 102C is located, relatively, to the right of the first integrated lid section 102A.



FIG. 6 illustrates an example top-down plane view in accordance with some example embodiments. As shown, the interior surface of sidewall 110 defines a single continuous surface extending from the circular base 112 up to and including the fully open plurality of integrated lid sections 102. Circular base 112 is attached to sidewall 110 around base seam 112A. Base seam 112A defines a circumference around circular base 112. Additionally, base seam 112A may attach circular base 112 to sidewall 110 by way of mechanical and/or chemical means. For example, the exterior side of base seam 112A (not shown) may be defined by an edge of circular base 112 being bonded to an edge of sidewall 110 (e.g., circular bottom edge 110C) by way of an epoxy therebetween, and a mechanical crimping of the two edges together to further force the epoxy to at least partially penetrate each respective edge material.


As illustrated, by FIG. 6, at least sidewall 110 and circular base 112 define a retention cavity. In some embodiments, at least sidewall 110 and circular base 112 may be treated with a sealant to define a water tight retention cavity within the interior of the cup. In some embodiments, base seam 112A may be treated with at least the sealant used to treat sidewall 110 and circular base 112 to produce a water tight seam around the circumference of circular base 112. In some embodiments, sidewall 110, circular base 112, and one or more dividers (not shown) may define a plurality of water tight retention cavities within the interior of the enclosed enhanced integrated cup body. Moreover, FIG. 6, illustrates seam 103 between the third integrated lid section 102C and the fourth integrated lid section 102D.

FIG. 7 illustrates an example bottom-up plane view in accordance with some example embodiments, for example the exemplary enhanced integrated cup shown in FIG. 6. FIG. 7 illustrates the exterior surfaces of sidewall 110, circular base 112, and the plurality of open integrated lid sections 102. As shown, seam 103 is defined by the overlapping edges of a first end 110A of sidewall 110 and a second end 110B of sidewall 110. Seam 103 extends up the length of sidewall 110 from circular base 112 up to a top portion of integrated lid sections 102C and 102D.



FIG. 8 illustrates an example of a partially-folded plurality of integrated lid sections in accordance with some embodiments. The third integrated lid section 102C and the fourth integrated lid section 102D are illustrated in a folded position. The third integrated lid section 102C and the fourth integrated lid section 102D are folded inward toward the center of the opening defined by the top portion of the cup body. As shown, the third integrated lid section 102C and the fourth integrated lid section 102D are bent substantially at a ninety degree angle to sidewall 110 along fold lines 108.

FIG. 9 illustrates another example of a partially-folded plurality of integrated lid sections in accordance with some embodiments. Similar to the embodiment illustrated in FIG. 8, FIG. 9 depicts the third integrated lid section 102C and the fourth integrated lid section 102D in the folded position. Additionally, the first integrated lid section 102A, configured with slit 104, is illustrated in a folded position. As shown, the first integrated lid section 102A, configured with slit 104, is bent substantially at a ninety degree angle relative to sidewall 110 along fold lines 108. The first integrated lid section 102A, configured with slit 104, is shown overlapping the third integrated lid section 102C and the fourth integrated lid section 102D in the folded position. The second integrated lid section 102B, configured with tab 106, is still in its respective open position. As shown, the second integrated lid section 102B, configured with tab 106, extends upward and is substantially parallel with sidewall 110.



FIG. 9 further illustrates a first graphical design print 902 that comprises a triangle logo with a snowflake logo enclosed by the triangle logo. Additionally, a second graphical design print 904 is shown that illustrates a plurality of text based characters printed on sidewall 110 spelling out “Frozen” below the first graphical design print 902. In some embodiments, graphical design prints 902 and 904 may be vinyl decals (i.e. stickers, etc.) applied with adhesive to sidewall 110 while the enhanced integrated cup is at least partially assembled for use by a consumer. For example, a food service facility may pre-print rolls of graphical design prints indicating, for example, the temperature of the contents of the cup and a food service employee may apply the appropriate graphical design print(s) prior to presenting the cup to a consumer.



FIG. 10 illustrates a fully-folded plurality of integrated lid sections in accordance with some embodiments. Similar to the embodiments illustrated in FIGS. 8-9, FIG. 10 depicts the first integrated lid section 102A, the third integrated lid section 102C, and the fourth integrated lid section 102D in their respective folded positions. Further, FIG. 10 illustrates, the second integrated lid section 102B, configured with tab 106, in a folded position with tab 106 interlocked with at least slit 104 of the first integrated lid section 102A. As shown, the second integrated lid section 102B, configured with tab 106, is bent substantially at a ninety degree angle relative to sidewall 110 along fold lines 108. The plurality of interlocked integrated lid sections 102 and cutout 302 define a drinking opening in the integrated lid of the cup body. FIG. 10 further illustrates a example embodiments of a handle 1002 attached to sidewall 110 of the cup body. In some embodiments, handle 1002 may be configured as a carry handle (not shown) configured to extend over the plurality of interlocked integrated lid sections 102.



FIGS. 11A, 11B, 11C, and 11D illustrate an example folding procedure in accordance with some embodiments. As depicted, by FIG. 11A, the exemplary enhanced integrated cup 1102 is shown with a fully opened plurality of integrated lid sections extending from the top portion of the sidewall. As shown, by FIG. 11B, step 1104 occurs by folding the third integrated lid section 102C and the fourth integrated lid section 102D down along their respective fold lines and over the interior cavity defined by the cup body. Step 1106 as illustrated in FIG. 11C includes at least the first integrated lid section 102A being folded down along its respective fold line and over the interior cavity defined by the cup body. The first integrated lid section 102A overlaps the third integrated lid section 102C and the fourth integrated lid section 102D. FIG. 11D shows step 1108 that includes at least the second integrated lid section 102B being folded down along its respective fold line and over the interior cavity defined by the cup body. The second integrated lid section 102B further overlaps the integrated lid sections 102A, 102C, and 102D when in its respective folded position. Step 1110 is further shown in FIG. 11D to include at least the insertion of tab 106, of the second integrated lid section 102B, into slit 104, of the first integrated lid section 102A.


In some embodiments, the fully opened plurality of integrated lid sections may be first bent outward to provide easier access to the interior cavity of the cup body (e.g., to insert a food product, beverage, etc.) before being bent inward to interlock the plurality of integrated lid sections, such as described with respect to at least FIGS. 11A, 11B, 11C, and 11D. In some embodiments, the interlocked plurality of integrated lid sections may define a flat, convex or concave shape. For example, the interlocked plurality of integrated lid sections may bend inward toward the bottom of the cup body (i.e. the circular base) to define a concave lid. For additional example, the interlocked plurality of integrated lid sections may bend outward away from the bottom of the cup body (i.e. the circular base) to define a convex lid. In some embodiments, the plurality of integrated lid sections may comprise one or more of mechanical or chemical means to provide a water tight lid. For example, one or more integrated lid sections may be configured with a pressure activated chemical adhesive, or the like, on at least one of their respective exterior surfaces that is configured to attach to another one or more integrated lid sections when the plurality of integrated lid sections are interlocked with each other. In some example embodiments, the interior surfaces of the plurality of integrated lid sections may be treated with additional sealant material to prevent leakage through the seams defined by the plurality of interlocked integrated lid sections.



FIG. 12 illustrates another example embodiment of a cup 1200 with an integrated folding lid. As shown, the cup 1200 includes a body formed of a sidewall 1210 and bottom (not shown), while the integrated folding lid is formed by integrated lid section 1202. The integrated lid section 1202 of the illustrated embodiment includes a tab 1206 and a slot 1204 to receive the tab when the integrated lid section is in the folded configuration, and secure the folded lid in a folded, closed position. As shown in FIG. 12, the integrated lid section is unitary extending around a substantial portion of a circumference of a top edge 1211 of the sidewall 1210. The integrated lid section 1202 does not extend across a break in the lid section that forms a spout 1212 when the integrated lid section is in the folded, closed position.


The integrated lid section 1202, to form the folded, closed lid, folds in upon itself at fold lines, whereby individual lid sections of the continuous, integrated lid section 1202 are formed. This continuous integrated lid section 1202 that extends around the top edge 1211 of the sidewall 1210 along all portions other than where the spout 1212 is formed provides a more spill-resistant lid for the cup, improving consumer satisfaction and reducing unwanted spills from the cup, such as when a cup is being carried by hand or secured in a cup holder and exposed to significant movement.


As illustrated in FIG. 12, the spout 1212 area includes a raised portion of the top edge 1211 that extends above the majority of the remaining portion of the top edge. This feature aids in conveying fluids from an internal cavity of the cup to a user's mouth while reducing the likelihood of drips from the spout after a user has consumed contents of the cup.



FIG. 13 illustrates the cup 1200 of FIG. 12 with the integrated lid section 1202 in the folded, closed configuration. As shown, the integrated lid section 1202 forms a first distinct lid section 1202A and a second distinct lid section 1202B by virtue of folds along the integrated lid section 1202. Also shown and only partially visible is a third distinct lid section 1202C. FIG. 14 illustrates a top view of the cup with the integrated lid section 1202 folded, but the tab 1206 not yet received in the slot (generally not visible behind the tab in FIG. 14). The illustrated embodiment of the tab 1206 includes a slit 1207 in the tab. This slit 1207 is positioned at a base of the tab 1206 and functions to secure the lid in a closed position as described further below.



FIG. 15 illustrates a top view of the cup 1200 with the integrated lid section folded to form the three distinct lid sections. As shown, the third distinct lid section 1202C top edges shown as heavy, dashed lines 1203 fold in such a way along fold lines 1205 shown as lighter, dotted lines such that the inner cavity of the cup securely holds fluid and does not allow fluid to spill from a back side of the cup, opposite the spout 1212. This folding method provides a spill-resistant cavity that is desirable in a portable beverage cup.



FIG. 16 illustrates a side view of the cup 1200 with the integrated lid section in the folded, closed position such that in profile the top edge 1211 of the sidewall 1210 is visible. As shown, the top of the cup 1200 defines a curved profile, with the spout 1212 rising above substantially the remainder of the folded lid. This profile is defined by the top edge 1211 of the sidewall 1210 along which the integrated lid section 1202 is folded to form the lid. This configuration provides a more accessible drinking spout 1212. The specific profile defined by the top edge 1211 of the sidewall 1210 allows a user to place their mouth at the spout 1212 of the cup 1200 and tilt the cup up without the top of the cup interfering with a nose or facial hair, for example. Further, the spout 1212 of the illustrated embodiments serves to funnel the contents of the cup to the spout 1212 as the cup is tilted toward the mouth of a user.


While the illustrated profile of the concave top curvature defined by the top edge 1211 of the sidewall 1210 provides enhancements to use and user convenience and satisfaction, the configuration further provides for a more secure and robust closure of the integrated lid section 1202 in the folded, closed position. Referring back to FIG. 13, the tab 1206 engages the slot 1204 along the concave curvature of the closed lid. This benefits the closure in several ways. The concavity holds the engagement between the tab 1206 and the slot 1204. As the lid is not merely flat, the concavity induces a force upon the engaged members that resists opening. To open the lid, the first distinct lid section 1202A and the second distinct lid section 1202B would have to move from their concave positions, passing through a flat position, to a convex position that is formed when the lid is fully opened as shown in FIG. 12. The concavity of the top surface profile thus holds engagement between the tab 1206 and the slot 1204, resisting unwanted opening.


The concave curvature of the top defined by the top edge 1211 also resists unwanted disengagement between the tab 1206 and the slot 1204. Conventional containers having folded lids that are of a flexible material will tend to force open a folded lid when the container is squeezed along the sidewalls. This is generally because the flat lid bows upwardly responsive to the cavity becoming smaller through squeezing of the sidewalls. However, according to the illustrated embodiment, as the sidewall 1210 is squeezed, such as by a hand grasping the cup 1200, the first distinct lid section 1202A and the second distinct lid section 1202B will respond to the squeezing by bowing inwardly to become somewhat more concave, thereby driving the tab 1206 further into the slot 1204, further strengthening the closure of the lid. This interaction between the tab 1206 and the slot 1204 occurs regardless of the direction of squeeze placed upon the sidewall 1210 as the concavity of the lid responds to any such squeezing by concaving further inwardly, benefiting the closure of the integrated lid section 1202. Embodiments including the slit 1207 shown in FIX. X additionally benefit from the slit further securing the lid. As the tab 1206 is driven into the slot 1204, the slit 1207 permits engagement with an edge of the slot. This engagement precludes the tab 1206 from disengaging with the slot 1204. This benefit is significant over prior art embodiments of folding-lid containers and provides a distinct advantage in the functionality and utility of the embodiments described herein.


While the spout 1212 of the illustrated embodiments of FIGS. 12-17 are generally configured for sipping directly therefrom, other shapes of spouts are provided herein for different functional uses. For example, a straw-specific embodiment can include a substantially circular spout opening, or a boba tea embodiment may have a larger orifice to facilitate larger straws that generally accompany boba tea beverages. Further, a spout can be sized and shaped to accommodate a straw or sipping directly from the spout to be used with a wide array of beverages. A larger opening may be more appropriate for smoothies or thicker beverages, while smaller spouts may be more appropriate for hot beverages, such as coffees and teas. The spouts described herein can be employed using the general structure described above with respect to FIGS. 12-17.


Embodiments described herein can further employ an additional layer added to the sidewall to provide an insulative body of the cup. FIG. 17 illustrates such an embodiment with an insulative sidewall 1320 that includes a second layer of material over the first layer of the sidewall 1310 for a cup 1300. This insulative sidewall 1320 can be in the form of a secondary sidewall that provides more material between the contents of the cup 1300 and where a user would grasp the cup. The insulative sidewall can provide a more hydrophobic layer to resist the formation of condensation for cold beverages and provide a surface that can be printed to. Further, the ink used to print to the insulative sidewall 1320 may itself be hydrophobic, resisting condensation on the exterior of the cup 1300. The hydrophobic properties of the insulative sidewall 1320 may be inherent in the material from which the insulative sidewall is formed. Optionally, the hydrophobic properties of the insulative sidewall 1320 may be increased with a printed layer of hydrophobic ink. Such a layer of hydrophobic ink may provide a hydrophobic surface while also providing a graphical design on the insulative sidewall to connote a brand, an appealing design/color, or other information printed to the insulative sidewall 1320.


The insulative sidewall 1320 provides an overall wall thickness between the contents of the cup and an exterior surface that is greater than the thickness of the sidewall 1310 of the cup. The insulative sidewall 1320 can include a secondary layer of material that is adhered to the sidewall 1310. Optionally, the insulative sidewall can be formed as a sleeve, with the material formed in a frustoconical shape of an angle congruent with that of the sidewall 1310, and adhered to itself in a lap joint or but joint to form a complete sleeve. This sleeve can then be attached to the sidewall 1310, which may be facilitated by adhesive or rely upon frictional engagement. The insulative sidewall of an example embodiment can include a corrugated surface, wherein the corrugated surface reduces a portion of the insulative sidewall that a person would grasp and reduces thermal transfer between a fluid in the cup to a hand holding the cup.
