Abstract

A rimless lid (10, 97, 99) for a container is provided, the rimless lid comprising: a cover member having an outer portion (1), an inner portion (3), and a peripheral portion (5); and a reinforcing arrangement comprising one or more reinforcing members (30, 140, 530, 540, 630, 640) located on the inner portion (3) of the cover member, wherein at least one or more of the reinforcing members (30, 140, 530, 540, 630, 640) on the peripheral portion (5) of the cover member is configured to frictionally engage an interior wall of the container when the lid is attached.

Description

Technical Field

[0001] The present invention relates to, but is not limited to, lids for containers for viscous contents such as soups, porridges, noodles, or solid foods, or warm and / or cold beverages such as coffee, tea, soda, beer, etc.

Background Art

[0002] Disposable lids for disposable and reusable containers such as food or beverage cups are known. Some such lids have drinking apertures, while others are completely closed. Many lids for food or beverage containers are made of plastic. Disposable plastic lids are not environmentally friendly for many reasons. Paper or cardboard lids are biodegradable and thus more environmentally friendly than plastic lids. Paper lids are generally used for single-use soup cups, but are not known to be used for single-use beverage cups. Recently, paper lids have come to be used for single-use beverage cups. Generally, existing paper lids are difficult to make and bulky to store. Also, in many cases, they are either too loose or too tight for the container. In the former case, the lid is likely to fall off, and there is unease in handling the container. In the latter case, the lid is difficult to remove, and due to airtight suction, when the lid is removed, the contents scatter vigorously. Such lids are provided with small ventilation holes, but generally they are insufficient to relieve suction.

[0003] The present invention provides an improved lid for a food or beverage container that is more environmentally friendly, can be used more simply and safely compared to conventional lids, fits more simply and surely onto the container, facilitates both delivery and consumer use "at the destination", improves the consumer experience, reduces the storage space required by efficiently stacking, and can be manufactured relatively easily and at low cost.

Summary of the Invention

[0004] Therefore, in one embodiment of the present invention, a rimless lid for a container is provided, the rimless lid comprising A cover member having an outer part, an inner part, and a peripheral edge, A reinforcing configuration comprising one or more reinforcing members located on the inner side of the cover member, At least one or more reinforcing members on the periphery of the cover member are configured to frictionally engage with the inner wall of the container when the lid is attached.

[0005] Optionally, one or more reinforcing members hang down from the inside of the cover member.

[0006] Optionally, at least one reinforcing member is configured to frictionally engage with the inner wall of the container.

[0007] Optionally, the peripheral edge of the cover member is configured to frictionally engage with the inner wall of the container.

[0008] Optionally, the peripheral edge of the cover member and at least one reinforcing member are configured to frictionally engage with the inner wall of the container.

[0009] Optionally, any reinforcing members or each reinforcing member hanging from the cover member may frictionally contact the inner wall of the container at at least two separate positions on the inner wall of the container.

[0010] Optionally, a reinforcing member comprising a reinforcing panel is provided. The reinforcing panel is connected to one or more reinforcing members hanging down from the inside of the cover member and is positioned substantially parallel to the cover member at a distance.

[0011] Optionally, the reinforcing panel is a shield panel.

[0012] Optionally, the reinforcing panel includes a peripheral edge configured to frictionally engage with the inner wall of the container.

[0013] Optionally, the peripheral edge of the cover member is reinforced, for example, by a thickened region or peripheral band.

[0014] Optionally, the periphery of the reinforcing panel member is reinforced by, for example, a thickened region or peripheral band.

[0015] Advantageously, the rimless lid according to the present invention is configured such that interlocking engagement with the container occurs only inside the container. Therefore, interlocking engagement can occur between the inside of the container and one or more reinforcing members, and / or between the periphery of the cover member.

[0016] Thus, the rimless lid structure is substantially fittable into the container so that, when the lid is attached, the lid cover member is substantially horizontal to the rim of the container. The rimless lid structure adheres securely to the container by frictional engagement of the cover member and / or reinforcing member with the inner wall of the container. This eliminates the need for a curved rim or an upright and / or hanging skirt around the outer edge of the lid for clipping or fitting onto the opening / rim of the container. For aesthetic and hygienic reasons, the outer portion of the lid cover member may protrude or extend across the top of the opening of the container.

[0017] Optionally, the cover member is substantially flat. As a result, when a drinking opening is provided in the lid's cover member, the container does not need to be tilted as much when drinking compared to when the lid surface is raised higher than the rim of the container or recessed below the rim.

[0018] Preferably, the rimless lid is made from a biodegradable, renewable, or compostable material such as paper, cardboard, corrugated cardboard, vegetable starch, or other suitable plant-based material. The applications of the present invention may extend beyond paper lids to lids made from plastics and other materials. Therefore, alternatively, the lid may be made of PET plastic for use with, for example, renewable PET plastic cups. Alternatively, other materials may be used.

[0019] Rimless lids are suitable for use with containers for (1) viscous contents such as soup, porridge, and noodles, (2) solid foods such as french fries or popcorn, and (3) hot and / or cold beverages such as coffee, tea, soda, and beer, but are not limited to these.

[0020] The end edges of one or more reinforcing members (including reinforcing panels) are preferably positioned to fit snugly against the wall of the container and / or to deform (if the container material is deformable by one or more reinforcing members), thereby securely holding the rimless lid in place and providing rigidity to the rimless lid / container assembly. Additionally, one or more reinforcing members may provide structural support and rigidity to the lid itself. Furthermore, one or more reinforcing members may provide structural support and rigidity to the container.

[0021] In one configuration, at least one reinforcing member, preferably a hanging reinforcing member, extends across the inner portion of the cover member. The at least one reinforcing member preferably has a pair of container engaging portions located at opposing peripheral positions on the inner portion of the cover member, such that when the rimless lid is placed on the open top of the container, at least one hanging reinforcing member enters the container and the container engaging portions frictionally engage with the inner wall of the container at opposing peripheral positions on the container wall. In this way, the rimless lid can be secured to the container.

[0022] Optionally, the reinforcing member or each reinforcing member may be in frictional contact with the inner wall of the container at at least two separate locations on the inner wall of the container.

[0023] In any configuration, at least two such reinforcing members are provided, each reinforcing member extending across the inner portion of the cover member. The at least two reinforcing members may cross or intersect each other.

[0024] Furthermore, in any configuration, at least two reinforcing members are non-intersecting. Optionally, non-intersecting reinforcing members are substantially or broadly parallel to each other.

[0025] Also, it is possible and contemplated to achieve the required friction level in a number of other alternative configurations.

[0026] In any configuration, at least one reinforcing member is configured to engage the inner wall of the container at a number of distinct locations. For example, the reinforcing member may comprise three portions arranged in, for example, a "Z" shaped configuration in plan view and be configured to engage the inner wall of the container at four distinct locations. It will be appreciated that other alternative configurations are possible to provide the required number of distinct contact locations to achieve the desired level of frictional engagement between the rimless lid and the container.

[0027] In configurations where the reinforcing members cross or interleave with each other, appropriate cooperating slots or other openings can be made in each reinforcing member so that the reinforcing members can cross each other during assembly. The reinforcing members can structurally reinforce and strengthen both each other and the entire rimless lid structure by crossing and interlocking with each other.

[0028] Optionally, one or more reinforcing members of the rimless lid may comprise one or more ribs.

[0029] Optionally, one or more reinforcing members may be integrally formed with the cover member.

[0030] Optionally, the cover member of the rimless lid may be formed from a piece of planar sheet material such as, for example, cardboard and folded along predetermined lines to form the reinforcing member or each reinforcing member as a rib.

[0031] Optionally, for example, if the rimless lid is formed by molding, one rib or a plurality of ribs can be integrally molded with the cover member.

[0032] Alternatively, or in addition, the reinforcing member can be formed as a second rib from the cover member or from another piece of planar sheet material and attached (e.g., by adhesive, welding or another suitable method) to the inner portion of the lid.

[0033] Optionally, one or more reinforcing members are movable between an expanded state and a collapsed state. In the expanded state, one or more reinforcing members protrude from the inside of the cover member, allowing the container to be closed with the lid. When one or more reinforcing members collapse, they move closer to the cover member, preferably becoming coplanar with the cover member. This configuration allows multiple lids to be stacked for storage, minimizing the storage space required to store the lids.

[0034] In any configuration in which the reinforcing members intersect each other, the joint opening of the first and second reinforcing members can be configured to allow the first and second reinforcing members to intersect each other during assembly, and to move relative to each other and articulate with respect to the lid while the first and second reinforcing members are moving between an extended state and a collapsed state. In one configuration, each of the first and second reinforcing members has a fold line or hinge line near the lid. For example, when a user applies an external force to the first and second reinforcing members, moving them from an extended state to a collapsed state, the first and second reinforcing members can articulate with respect to the lid around their respective hinge lines, thereby allowing them to move closer to the lid. To extend the first and second reinforcing members, they pivot in opposite directions around their respective hinge lines, i.e., away from the lid, until, for example, an external force is applied by the user, the first and second reinforcing members protrude outward from the inside of the lid. Preferably, the interaction between the reinforcing members can be used to firmly click and fix them in place, for example, by securely holding the reinforcing members in the extended position with appropriate cooperating slots.

[0035] In any configuration where only a single reinforcing member is present, or where the reinforcing members do not intersect each other, the reinforcing member may be foldable or collapsible flat relative to the lid, and may be movable between the folded / collapsed state and the unfolded or extended state.

[0036] Optionally, when in the expanded state, the reinforcing member may be fixed in the expanded position with a fastening arrangement.

[0037] Several configurations are possible for the appropriate fastening setup.

[0038] Optionally, in one configuration, the fastening configuration includes a movable tab or clip configuration, the movable tab or clip being a cut-out portion of a reinforcing member that is pushed from a closed position to an open position, and by creating an angle of approximately 90 degrees along the cross-section of the reinforcing member, prevents the reinforcing member from collapsing and the lid from moving together and folding back into a collapse / folded position. Once the movable tab or clip is pushed to the open fixed position, the reverse movement of the fastening tab or clip can be prevented by forming a return stopper, such as a raised line or fold, on the lid, which is configured to prevent it from returning to its original position.

[0039] The container may have a rim that is circular, rounded rectangular, or of other shape. The rimless lid may have a shape that is generally suitable for the shape of the container. An advantageous configuration is to slightly alter the shape of the container or the shape of the rim and rimless lid to increase friction between the container and the rimless lid and ensure a more secure closure. For example, if the rim of the container is circular, the rimless lid may be elliptical. In this example, when the rimless lid closes the container, at least one reinforcing member frictionally engages with the inner wall of the container and deforms (if the container material is deformable by at least one reinforcing member), and the elliptical shape of the rimless lid has the effect of making the contact between the container and the rimless lid stronger, ensuring a more secure closure, increasing the rigidity of the rimless lid / container assembly, and improving the structural strength and rigidity of the retaining container.

[0040] As described above, in the example, the rimless lid may include a panel-shaped reinforcing member provided on the inside of the cover member and spaced apart from it.

[0041] Optionally, the reinforcing panel is separated from the inner part of the cover member by one or more reinforcing members.

[0042] Optionally, the reinforcing panel is a shield panel.

[0043] In this specification, the terms “reinforcement panel” and “shield panel” are to be understood to be synonymous and interchangeable.

[0044] The reinforcing panel may be sized and shaped such that its periphery fits snugly against the inner wall of the container. This provides additional rigidity to the rimless lid / container assembly, making the container safer to handle. For example, the reinforcing panel may be shaped to closely match the shape of the container wall at a level where the reinforcing panel is located inside the container when the rimless lid is placed on top of the container. If the container rim is circular and the rimless lid is elliptical, the reinforcing panel may also be elliptical. In the latter case, when the rimless lid closes the container, the periphery of the reinforcing panel engages with and deforms the container wall (if the container material is deformable by the shield panel), and the elliptical shape of the reinforcing panel increases the rigidity of the lid / container assembly. While providing rigidity to the rimless lid / container assembly, the reinforcing panel snugly fits and seals the rimless lid to the container, securely holding the lid on the beverage container while preventing leaks. In addition, the reinforcing panel separates the contents of the container from the inside of the rimless lid cover member and the rim of the container.

[0045] Optionally, the shield panel is planar. The shield panel may be formed from a single sheet material or from a molded material.

[0046] The shield panel may have reinforced, raised, or thickened areas around its outer periphery or edge (either all or in several places). These raised areas can be created in several ways; for example, the outer periphery of the shield panel can be curled (similar to the curl used around the rim of a disposable beverage cup). Alternatively, the periphery can be thickened or reinforced in other ways, or another large circular band can be attached to the outer periphery of the shield panel by bonding, welding, or other means. In the case of molded shield panels, such reinforced areas can be provided around the outer periphery of the shield panel by adjusting the shape of the mold.

[0047] The main purpose of providing raised or thickened areas around the outer periphery of the shield panel is to increase the structural strength of the shield panel and to increase the friction level between the shield panel and the inner wall of the container during use, thereby making the closing friction between the lid and the container more robust and reliable.

[0048] The shield panel may include appropriate reinforcing members that cross the planar area to provide additional structural strength to the shield panel. Such reinforcement can be achieved in several ways, such as by adding one or more reinforcing bands or ribs.

[0049] As described above, the shield panel may be attached to the inside of the lid cover member via one or more reinforcing members. In this way, one or more reinforcing members of various arbitrary examples function as connectors connecting the cover member and the shield panel, and as spacers that keep the shield panel separated from the cover member.

[0050] In examples where the reinforcing members are collapsible, one or more reinforcing members, when in the extended state, keep the cover member and shield panel separated from each other, so that the composite structure of the cover member, reinforcing member, and shield panel closes the beverage container. When one or more reinforcing members are in the collapsed / folded state, the cover member and shield panel move together, reducing or eliminating the space between the cover member and shield panel. Such a collapsed / folded configuration allows multiple rimless lids to be stacked and stored in a flat pack configuration, minimizing the storage space required to store the lids.

[0051] The extended state between the lid and the shield panel may be securely fixed and held in place by a fastening mechanism. This fastening mechanism can be released by the user, allowing the lid and shield panel to return to the collapsed / folded position.

[0052] The fastening configuration can take several forms depending on the configuration of the reinforcing members.

[0053] In some configurations, the reinforcing members do not intersect with each other, are completely or partially parallel, or form a "Z" shape. The fastening configuration may include a movable tab or clip configuration, the tab or clip being pushed from a closed position to an open position, creating an angle of about 90 degrees along the cross-section of the reinforcing member, preferably on each reinforcing member, thereby preventing the reinforcing members from collapsing and preventing the lid and shield panel from moving together and folding back into a collapsed / folded / flat-packed position.

[0054] Once the fastening tab or clip is pushed to its open, fixed position, it can be prevented from returning to its original position by a retaining mechanism such as a raised line or fold at an appropriate holding position on the cover member and / or shield panel.

[0055] In configurations where reinforcing members intersect or cross each other (at any angle of 90 degrees to each other), the fastening configuration may be a hinge-like structure.

[0056] One or more reinforcing members may be in the form of a first rib and a second rib, as described above. In this configuration, the first rib is preferably permanently attached to or formed together with one of the cover member and the shield panel. The second rib is preferably permanently attached to or formed together with one or both of the cover member and the shield panel and is releasably attached to the other of the cover member and the shield panel. The second rib may be releasably attached to the cover member and the shield panel by a suitable fastening configuration. The fastening configuration prevents the first and second ribs from collapsing. The fastening configuration may include, for example, a tab provided on the second rib and a slot formed in the cover or shield panel on the side to which the second rib is detachably attached. When the first and second ribs are extended, the tab engages with the slot, and the second rib does not articulate with respect to the side of the cover member or shield panel to which the second rib is attached. In this configuration, the first rib has a pair of hinge wires, one of which is closer to the cover member and the other closer to the shield panel. The second rib has a second hinge wire near the side of the cover member or shield panel to which the second rib is attached. For example, when an external force is applied to the cover member and shield panel by a user pushing them toward each other, the first and second ribs move from an extended state to a collapsed state, releasing the fastening configuration (or, in certain configurations, the tab of the second rib disengages from its slot), and the second rib disengages from the side of the cover member or shield panel to which the second rib is fastened via the fastening configuration. At the same time, the first rib can articulate with respect to the cover member and shield panel around the first hinge wire, and the second rib can articulate with respect to When both the first and second ribs articulate around their respective first and second hinge lines, the cover member and shield panel move closer together, reducing or eliminating the space between them.To return the first and second ribs to their extended state, the user applies force to the cover member and shield panel in a direction that spreads them apart, and then repeats the above steps in reverse order. Finally, when the second rib returns to its extended state, the fastening mechanism engages (or, in certain configurations, the tab on the second rib engages with a slot), causing the second rib to engage with the cover member or shield panel to which the second rib is fastened via the fastening mechanism, so that the second rib and the entire assembly are fixed in the extended state. Alternatively, the ribs may be interconnected in a substantially similar manner.

[0057] The shield panel (i.e., the reinforcing panel) may include vents or notches of appropriate size and position to allow for the release of pressure accumulated by vapors or gases generated by contents containing high-temperature contents or gases.

[0058] By forming a raised line or fold on the inner wall of the container so as to bypass all or part of the container wall directly below where the shield panel contacts the inner wall of the container, the secure fastening and gripping of the lid to the container can be enhanced. The shield panel effectively clips under this raised line or fold, helping to secure the shield panel in an optimal holding position and prevent the shield panel from loosening its contact with the container.

[0059] An opening may be formed in the cover member so that liquids can be drunk, poured, or solid foods picked up from the container without removing the lid.

[0060] The opening used for drinking may be curved so that the consumer's lips can make full, direct, and unobstructed contact with the rim of the beverage container, allowing the consumer to drink directly from the container rather than through an enclosed opening in the lid. This configuration significantly improves the consumer's drinking experience.

[0061] In one configuration, the rimless lid may include a flap. The flap is formed in the cover member and initially seals the opening. The cover member may further include a weakened area provided, for example, by serrations, perforations, or thinning of the lid material. The weakened area defines the flap, and the flap can be pulled back to open the opening, but until opened, the lid is completely sealed closed with the flap.

[0062] In the second configuration, the flap may be repeatedly opened and securely closed between uses to prevent splashing or spilling from the container. The flap may be constructed to remain fixed in either the open or closed position together with the lid for the convenience of the user.

[0063] In addition to providing a drinking opening, a flow deflection configuration may be provided on the inner side of a cover member adjacent to the drinking opening. Preferably, the flow deflection configuration is configured to prevent liquid contained in the container, particularly splashy, watery liquids, from splashing straight up from the drinking opening when the container is in a substantially upright position. More preferably, the flow deflection configuration is configured to allow the liquid to approach the drinking opening laterally or indirectly so that the liquid loses most of its energy / momentum before reaching the drinking opening, thereby reducing the possibility and intensity of unexpected spills or splashes when drinking or pouring from the container. In one configuration, the flow deflection configuration comprises a portion positioned substantially in front of the drinking opening to deflect splashing liquid or prevent splashing liquid from flowing directly into the drinking opening.

[0064] In one configuration, the shield panel described above is adapted to function as a flow deflection configuration.

[0065] For this purpose, in one possible configuration, the shield panel may have one or more notches near the drinking opening to define a flow opening. These notches may define the flow opening together with the inside of the container.

[0066] If the container is tilted while drinking, the liquid will flow from the flow vent towards the drinking opening. When the container is upright, the shield panel prevents splashes caused by the container's movement from reaching the drinking opening.

[0067] In the second configuration, the flow opening may include a notch. The notch is located entirely within the perimeter of the shield panel, but is sufficiently adjacent to the inner side of the cover member to facilitate flow from the container through the notch when the container is tilted.

[0068] An intermediate well can be created between the shield panel and a second panel positioned flat and above the shield panel before the lid is fitted onto the cup, which functions as a flow deflector to prevent direct splashing from the container. The second panel is shaped to overlap the shield panel in the area directly below the beverage opening, and is neither fixed nor glued to the shield panel in this position. The periphery of the second panel extends slightly longer than the periphery of the shield panel. As a result, when the lid is fitted onto the container, the second panel separates from the shield panel by contacting the inner wall of the container, creating an intermediate well or substantially enclosed space. One or more notches in the shield panel allow liquid to flow from the container into the intermediate well when the container is tilted. One or more notches in the second panel allow liquid to flow out of the intermediate well for drinking when the container is tilted. The notches in the shield panel and the second panel are spaced apart and not facing each other so that liquid cannot splash directly into the intermediate well, through the intermediate well, or out of the intermediate well in a direct line of motion. This design allows for a smooth flow and movement of the liquid, making it easy to drink or pour from the container, while preventing splashing.

[0069] Preferably, the container is a cup. The shape of the cup varies depending on the nature of the contents. For example, the contents may be a beverage that is drunk or poured directly from the container, a viscous food such as soup that is scooped or poured from the container with a spoon, or a solid food that is picked up from the container or taken out by tilting the container.

[0070] The rimless lids described herein apply to both single-use disposable lids and reusable lids.

[0071] It will be understood that the configurations of the above embodiments may be combined with other embodiments where appropriate, and / or actually form novel and inventive aspects on their own. [Brief explanation of the drawing]

[0073] Hereinafter, embodiments of the present invention will be described only as examples with reference to the accompanying drawings.

[0074] In the drawings, the rimless lids according to the present invention are generally indicated by reference numerals 10, 97, and 99. First, the common components of the rimless lids 10, 97, and 99 will be described. For brevity, the common components are indicated by the same reference numerals. The rimless lids 10, 97, and 99 comprise a cover member having an outer portion 1, an inner portion 3, and a peripheral portion 5. The rimless lids 10, 97, and 99 are fitted to the inner wall of a container 900 (see Figures 21 to 27) so as to be tightened around the open top of the container 900, as described below. The rimless lids 97 and 99 are fitted to the inner wall of the container so as to be tightly tightened, as described below. The rimless lids 10, 97, and 99 are preferably made from a renewable, biodegradable, or compostable material such as paper, cardboard, corrugated cardboard, vegetable starch, or other suitable plant material.

[0075] The inner portion 3 of the cover members of the rimless lids 10, 97, and 99 is provided with at least one reinforcing member 130, 140, 530, 540, 630, and 640. The reinforcing members hang down from the inner portion of the cover. The hanging reinforcing members 130, 140, 530, 540, 630, and 640 may be referred to as ribs. The reinforcing members or ribs 130, 140, 530, 540, 630, and 640 are configured to frictionally engage with the inner wall of the container, as described below.

[0076] Rimless lids 10, 97, and 99 are preferably suitable for containers for viscous fluids such as soup. However, it will be understood that rimless lids can be used not only with containers for solid foods but also with containers for hot and / or cold beverages such as coffee, tea, soda, and beer, although they are not limited to these uses.

[0077] The reinforcing members / ribs 130, 140, 530, 540, 630, and 640 are fitted tightly to the walls of the container and / or adapted to deform (if the container material is deformable by the ribs 130, 140, 530, 540, 630, and 640). This securely holds the rimless lids 10, 97, and 99 in place and provides rigidity to the rimless lids 10, 97, and 99 / container assembly. In addition, the ribs 130, 140, 530, 540, 630, and 640 provide structural support and rigidity to the rimless lids 10, 97, and 99 themselves.

[0078] As shown in Figures 1, 5, 9, and 15, each rib 130, 140, 530, 540, 630, 640 extends across the inner portion 3 of the cover member of each lid 10, 97, 99. Each rimless lid 10, 97, 99 has at least one, preferably, pair of ribs 130, 140; 530, 540; and 630, 640. Each pair of ribs 130, 140; 530, 540; and 630, 640 may intersect or cross each other. Cooperative slots 135, 145; 535, 545 and notches 670, 671 are made in each rib 130, 140; 530, 540; and 630, 640 so that the ribs 130, 140; 530, 540; and 630, 640 can intersect each other during assembly. Alternatively, in this example, the ribs may not intersect.

[0079] As shown in detail in Figure 24, each reinforcing member 130, 140, 530, 540, 630, 640 has pairs of opposing container engaging portions 130a, 130b, 140a, 140b, 530a, 530b, 540a, 540b, 630a, 630b, 640a, 640b located at opposing peripheral positions on the inner portion 3 of the rimless lids 10, 97, 99. When the cover members of the rimless lids 10, 97, and 99 are placed on the open top of the container, the reinforcing members 130, 140, 530, 540, 630, and 640 enter the container, and the container engaging portions 130a, 130b, 140a, 140b, 530a, 530b, 540a, 540b, 630a, 630b, 640a, and 640b frictionally engage with the inner wall of the container. In this way, the rimless lids 10, 97, and 99 are fixed to the container.

[0080] In the examples shown in Figures 1-7, the rimless lids 10 and 97 are formed from pieces of a flat sheet material, such as cardboard, and are folded along predetermined lines to form the first ribs 130 and 530. In the examples shown in Figures 8-17, the first rib 630 is formed from another piece of the flat sheet material and is attached to the inner part 3 of the lid 99 cover member (for example, by adhesive, welding, or another suitable method).

[0081] In the examples shown in Figures 1 to 3 and Figures 8 to 17, the second ribs 140, 640 are formed from a separate piece of planar sheet material and are attached (for example, by adhesive, welding or another suitable method) to the inner portion 3 of the cover member of the lid 10, 99. In the examples shown in Figures 4 to 7, the second rib 540 is formed as part of the reinforcing member of the shield panel 550 (described in more detail below). The shield panel 550, like the rimless lid 97, is formed from a piece of planar sheet material and is folded along predetermined lines to form the second rib 540.

[0082] In the examples shown in Figures 1-3 and 8-17, the reinforcing members / ribs 130, 140, 630, and 640 are movable between an expanded state and a collapsed state. In the expanded state (see Figures 1, 8, and 9), the ribs 130, 140, 630, and 640 protrude from the inner part 3 of the cover member of the lids 10 and 99, allowing the container to be closed using the lids 10 and 99. When the ribs 130, 140, 630, and 640 collapse (see Figures 12-16), they move closer to the cover member of the lids 10 and 99, preferably becoming coplanar with the cover member. This configuration allows multiple rimless lids 10 and 99 to be stacked and stored, minimizing the storage space required to store the rimless lids 10, 97, and 99. The cooperating slots 135, 145 and notches 670, 671 of each rib 130, 140, 630, 640 are configured to intersect with each other during assembly, and to move relative to each other while the ribs 130, 140, 630, 640 are moving between the expanded and collapsed states, allowing them to articulate with the lids 10, 99 cover members.

[0083] In the examples shown in Figures 1-3 and 8-17, each rib 130, 140, 630, and 640 has its respective hinge lines 175, 177, 675, and 677 near its respective cover member. For example, when a user applies an external force to the ribs 130, 140, 630, and 640, causing them to move from an extended state to a collapsed state, the ribs 130, 140, 630, and 640 can articulate with respect to the cover member around their respective hinge lines 175, 177, 675, and 677, thereby allowing them to move closer to the cover member. To extend the ribs 130, 140, 630, and 640, for example, by applying an external force, the user can pivot the ribs 130, 140, 630, and 640 around their respective hinge lines 175, 177, 675, and 677 in opposite directions, i.e., away from the rimless lids 10, 99, as shown as an example in Figure 18, until the ribs 130, 140, 630, and 640 protrude outwards from the inner part 3 of the lids 10, 99.

[0084] The cover members of the rimless lids 10, 97, and 99 may have a planar shape that is approximately circular or elliptical. In the example described, the rimless lids are elliptical in order to make stronger contact between the container and the rimless lids 10, 97, and 99, but the present invention is not limited to this particular shape. Elliptical rimless lids are particularly useful when closing containers with a rounded top. When the rimless lids 10, 97, and 99 close the container, the ribs 130, 140, 530, 540, 630, and 640 frictionally engage with and deform the inner wall of the container (if the container material is deformable by the ribs 130, 140, 530, 540, 630, and 640), and the elliptical shape of the lids 10, 97, and 99 increases the rigidity of the lids 10, 97, and 99 / container assembly.

[0085] In any configuration, such as the example shown in Figure 28, at least one reinforcing member is configured to engage with the inner wall of the container at a number of distinct locations. For example, the reinforcing member 700 may comprise three parts 700A, 700B, and 700C arranged in a "Z" shape when viewed in plan, with each edge and corner 701, 702, 703, and 704 configured to engage with the inner wall of the container at a distinct location. It will be recognized that other alternative configurations are possible to provide the number of distinct contact locations necessary to achieve a desired degree of frictional engagement between the rimless lid and the container.

[0086] In the embodiments shown in Figures 4 to 17, reinforcing members in the form of shield panels 550 and 650 are provided on the inner portion 3 of each lid 97 and 99 cover member. The shield panels are connected to one or more reinforcing members that hang down from the inner portion of the cover member, and the reinforcing panels are positioned substantially parallel to and away from the cover member. The reinforcing panels have periphery portions configured to frictionally engage with the inner wall of the container.

[0087] The shield panels 550 and 650 are sized and shaped such that their periphery fits snugly against the inner wall of the container, as shown in Figure 21. This provides further rigidity to the rimless lid 97, 99 / container assembly, making the container safer to handle. The shield panels 550 and 650 may also be shaped such that their periphery closely conforms to the plane of the container wall at a level where the shield panels 550 and 650 are located inside the container when the rimless lid 97, 99 is placed on top of the container. In the examples in Figures 4 to 17, the shield panels 550 and 650 are elliptical in shape. Therefore, when the rimless lid 97, 99 closes the container, the periphery of the shield panels 550 and 650 deforms the container wall (if the container material is deformable by the shield panels 550 and 650), and the elliptical shape of the shield panels 550 and 650 increases the rigidity of the rimless lid 97, 99 / container assembly. The rimless lids 97 and 99 provide rigidity to the container assembly, while the periphery of the shield panels 550 and 650 fits snugly to securely fasten the rimless lids 97 and 99 to the container, thereby preventing leakage while ensuring the lids 97 and 99 are securely held on the beverage container. In addition, the shield panels 550 and 650 separate splashes of the container's contents from the inner part 3 of the lids 97 and 99 and the rim of the container.

[0088] In some modifications, the rimless lids 10, 97, 99 may optionally be provided with a drinking opening 7 in the cover member so that the rimless lids 10, 97, 99 can be used for drinking. As shown in Figures 1, 2, 4-5a, 8, 9 and 15-17, the rimless lids 10, 97, 99 may be provided with a flap 57. The flap 57 is formed in the cover member and initially closes the drinking opening 7. The rimless lids 10, 97, 99 may further be provided with a weakened area 507, provided, for example, by perforations or thinning of the lid material. The weakened area defines the flap 57, and the flap 57 can be peeled back to open the drinking opening 7. Until opened, the cover member of the rimless lids 10, 97, 99 is completely sealed closed together with the flap 57.

[0089] As shown in Figure 30 as an example, the beverage opening 70 may be formed in the cover member in a curved and / or shape so that the consumer's lips can make full, direct, and unobstructed contact with the rim 901 of the beverage container 900, allowing the consumer to drink directly from the container rather than through an enclosed opening in the lid. Such an opening 70 may be defined by a segment having a curved or arc-shaped code 71 that is cut or otherwise removed from the peripheral edge 5 of the rimless lid cover member. Such an opening 70 that exposes a relatively long portion of the rim 901 of the container greatly enhances the consumer's drinking experience.

[0090] In a modified version in which a drinking opening 7 is provided, flow deflection configurations 500, 600 are provided on the inner part 3 of the lid 97, 99 cover members adjacent to the drinking opening 7. The flow deflection configurations 500, 600 are configured to prevent the liquid contained in the container, especially splashy liquids, from splashing straight up from the drinking opening 7 when the container is in a nearly upright position. The flow deflection configurations 500, 600 are further configured to allow the liquid to approach the drinking opening 7 from the side or indirectly so that the liquid loses most of its energy / momentum before reaching the drinking opening 7, thereby reducing the possibility and intensity of unexpected spills or splashes when drinking or pouring from the container.

[0091] The flow deflection configuration includes a portion substantially positioned in front of the drinking opening 7 to deflect splashing liquid or prevent splashing liquid from flowing directly into the drinking opening 7. In the examples of Figures 4 to 17, reinforcing members in the form of the shield panels 550, 650 described above are adapted to function as the respective flow deflection configurations 500, 600. For this purpose, the shield panel has one or more openings near the drinking opening 7 so as to define a flow opening 21 together with the inner portion 3 of the rimless lid 97, 99 cover member. The opening may be in the form of one or more notches 551 on the periphery of the shield panel, as shown in example in Figure 4, or in the form of one or more openings 551A provided in the shield panel, as shown in example in Figure 8A. When the container is tilted during drinking, the liquid enters the flow opening 21 through an opening, for example, between the notch 551 and the wall of the container, or through the opening 551A of the shield panels 550, 650, and flows toward the drinking opening 7. When the user tilts the container to sip the liquid, the liquid first encounters the flow deflectors 500, 600, and then approaches the drinking opening 7 through the flow opening 21. In this way, the liquid loses most of its energy / momentum by first encountering the flow deflectors, i.e., the shield panels 500, 600, thereby providing a smoother flow through the drinking opening 7 when sipping. When the container is in an upright position, the shield panel reinforcing members 550, 650 prevent splashes from reaching the drinking opening 7.

[0092] As described above, the shield panel reinforcing members 550 and 650 are connected to the inner part 3 of the cover members of the lids 97 and 99 by ribs 530, 540, 630, and 640. The ribs 530, 540, 630, and 640 function as connectors that connect the cover members of the lids 97 and 99 to the shield panels 550 and 650, and also function as spacers that keep the shield panels 550 and 650 away from the inner part 3 of the cover members.

[0093] In the examples shown in Figures 4 to 7, a second rib 540 is formed as part of the shield panel 550. The shield panel 550, like the cover member, may be formed from a piece of planar sheet material and folded along predetermined lines to form the second rib 540. During assembly, the ribs 530 of the lid 97 cover member and the ribs 540 of the shield panel 550 intersect with each other via slots 535 and 545, joining the cover member and the shield panel 550.

[0094] As described above, in the examples shown in Figures 8 to 17, the reinforcing ribs 630 and 640 are movable between an extended state and a collapsed state. In the extended state, the reinforcing ribs 630 keep the cover member and the shield panel 650 separated from each other, so that the container can be closed using the lid 99 (see Figures 8 and 9). When the reinforcing ribs 630 and 640 collapse (see Figures 14 and 15), the cover member of the lid 99 and the shield panel 650 move together, reducing or eliminating the space between the cover member and the shield panel 650. This configuration allows multiple rimless lids 99 to be stacked and stored, minimizing the storage space required to store the rimless lids 99. The ribs 630 are attached to or formed together with the cover member and the shield panel 650, respectively. The ribs 640 are attached to or formed together with the cover member and are releasably attached to the shield panel 650 by an appropriate fastening configuration. The fastening configuration prevents the ribs 630 and 640 from collapsing. In the example shown in Figures 8 to 17, the fastening configuration comprises a tab 660 provided on the rib 640 and a slot 661 formed in the shield panel 650. As shown in Figures 8 to 17, in the extended state of the reinforcing members / ribs 630 and 640, the tab 660 engages with the slot 661, so that the rib 640 does not articulate with the lid 99. The rib 630 has a pair of first hinge wires 675, one of which is closer to the shield panel 650 and the other is closer to the lid 99. The rib 640 has a hinge wire 677 near the lid 99. For example, when a user applies an external force to the lid 99 and the shield panel 650 such that they push the cover members of the lid 99 and the shield panel 650 toward each other, the ribs 630 and 640 move from an extended state to a collapsed state, the tab 660 disengages from the slot 661 and the rib 640 disengages from the shield panel 650. At the same time, the rib 630 can be articulated with respect to the lid 99 and the shield panel 650 around the hinge line 675, and the rib 640 can be articulated with respect to the lid 99 around the hinge line 677.When the two ribs 630 and 640 articulate around their respective hinge lines 675 and 677, the cover member and the shield panel 650 move closer together, reducing or eliminating the space between the lid 99 and the shield panel 650. To return the ribs 630 and 640 to their extended state, the user applies force to the cover member and the shield panel 650 in a spreading direction, separating them, and repeats the above steps in reverse order. Finally, when the rib 640 returns to its extended state, the tab 660 engages with the slot 661, and the rib 640 engages with the shield panel 650, so that the rib 640 and the entire assembly are fixed in the extended state.

[0095] In the examples shown in Figures 18, 19, and 20, the reinforcing members are non-intersecting and non-crossing, but are substantially or partially parallel 710, 720, as shown in the example of Figure 29, for example, or in a "Z" configuration 700, as shown in the example of Figure 28. The configuration may be provided to maintain the reinforcing members in an extended state and may include a tab / flap configuration. This allows tab / flap forming sections 800, optionally expanding forming sections, provided at one or both ends of the reinforcing members, to move from a closed position (Figure 19) to an open position (Figure 20), forming an angle of about 90 degrees along the cross-section of the reinforcing members, preferably on each reinforcing member. This wedges the inner portion 3 of the cover member and the shield panel, preventing each reinforcing member from collapsing and preventing the cover member and shield panel from moving together and folding back into a collapse / fold / flatpack position as shown in Figure 18. It will be understood that the movable tabs can be positioned at locations other than the ends along the reinforcing members.

[0096] Once the movable tab or flap forming portion is pushed to an open, fixed position between the cover member and the shield panel, undesirable reverse movement can be prevented by appropriate anti-return forming portions, such as raised lines or folds 801 at preferred holding positions on the cover member and / or shield panel, which are configured to capture the flap 800 and prevent it from disengaging from the engagement between the cover member and the shield panel.

[0097] As shown in Figure 22, the peripheral edges 552 of the shield panel reinforcing members 550 and 650 may be curled 553 to increase the rigidity of the shield panel.

[0098] As shown in Figure 23, the shield panel reinforcing members 550 and 650 may be equipped with an auxiliary layer 554 to increase the rigidity of the shield panel. The auxiliary layer may be made of any suitable material or structure.

[0099] As shown in Figure 24, the rimless lid structure according to the present invention is substantially fittable into the container such that the lid cover member 99 is substantially horizontal to the rim 901 of the container 900 when the lid is attached. The rimless lid structure adheres securely to the container by frictional engagement of the cover member and / or reinforcing member with the inner wall of the container. This eliminates the need for a curved rim or an upright and / or hanging skirt around the peripheral edge 5 of the lid for clipping or fitting over the opening / rim of the container. For aesthetic and hygienic reasons, the outer portion 1 of the lid cover member may protrude or extend across the top of the opening of the container, as shown in Figures 21, 22, 23, 24, 26 and 27. As shown in Figure 25, the peripheral edge 5 of the cover member may be substantially within the rim of the container, close to the upper edge of the container rim.

[0100] Referring to Figures 26 and 26, in the example of a rimless lid, an intermediate well 1000 may be formed between the shield panels 550, 650 and a second panel 1100, which is positioned flat and above the reinforcing panels 550, 650 before the rimless lid is fitted onto the container, and which functions as a flow deflector to prevent direct splashing from the container 900. The second panel 1100 is shaped to overlap the reinforcing panels 550, 560 in the area directly below the beverage openings 7, 70, and is not fixed or glued to the reinforcing panels in this position. The periphery 1200 of the second panel 1100 extends slightly longer than the periphery 552 of the reinforcing panels 550, 560. As a result, when the rimless lid is fitted onto the container 900, the second panel 1100 separates from the reinforcing panels 550, 650 by contact with the inner wall of the container, creating the intermediate well 1000 or a substantially enclosed space. One or more notches in the reinforcing panels 550, 650 allow liquid to flow from the container 900 to the intermediate well 1000 when the container is tilted, as shown in Figure 27. One or more notches 1300 in the second panel 1100 allow liquid to flow out of the intermediate well 1000 for drinking when the container 900 is tilted. The notches in the reinforcing panels 550, 560 and the second panel 1100 are spaced apart and not facing each other, i.e., staggered, so that liquid cannot enter or exit the intermediate well 1000 in a direct line of movement. This configuration facilitates drinking or pouring from the container 900 with a smooth flow of liquid, while preventing splashing.

[0101] Although specific examples of the present invention have been described above, it will be understood that modifications are possible within the scope of the present invention as defined in the attached claims.
