Description

Technical Field

[0001] This invention relates to a lid for a container that holds viscous contents, such as soup, porridge, or noodles, or solid food or hot and / or cold drinks, such as coffee, tea, soda, or beer, but is not limited thereto. Background Technology

[0002] Disposable lids for single-use and reusable containers such as food or beverage cups are well-known. Some of these lids have drinking holes, while others are completely closed. Many food or beverage container lids are made of plastic. Plastic disposable lids are not environmentally friendly for many reasons. Paper or cardboard lids are biodegradable and therefore more environmentally friendly than plastic lids. Paper lids are commonly used for disposable soup cups, but not for disposable beverage cups. Recently, paper lids have begun to be used for disposable beverage cups. Generally, existing paper lids are difficult to manufacture and bulky to store. They are also often installed on containers too loosely or too tightly. In the former case, the container is unsafe to handle because the lid can easily fall off. In the latter case, the lid is difficult to remove, and the suction caused by the airtightness makes it easy for the contents to splash forcefully when the lid is removed. The small vents provided on such lids are usually insufficient to reduce the suction.

[0003] This invention provides an improved lid for food or beverage containers that is environmentally friendly, easier and safer to use, easier and more secure to attach to containers, facilitates transport and use by consumers "on the go," provides an enhanced consumer experience, stacks efficiently to reduce storage space requirements, and is relatively easy and inexpensive to manufacture compared to prior art lids. Summary of the Invention

[0004] Therefore, in one embodiment of the present invention, a flangeless lid for a container is provided, the flangeless lid comprising:

[0005] A cover member having outer, inner, and outer edges; and

[0006] Reinforcing elements, including one or more reinforcing elements located inside the cover member;

[0007] At least one peripheral edge of the lid member or one or more reinforcing members is configured to frictionally engage the inner wall of the container when the lid is installed on the container.

[0008] Optionally, one or more reinforcing members may be dependent on the inside of the cover member.

[0009] Optionally, at least one reinforcing member is configured as the inner wall of the friction-jointed container.

[0010] Alternatively, the outer edge of the cover member is configured to form the inner wall of the friction-engaging container.

[0011] Optionally, the outer edge of the cover member and at least one reinforcing member are configured to frictionally engage the inner wall of the container.

[0012] Alternatively, the reinforcing members suspended from the cover member or each reinforcing member may make frictional contact with the inner wall of the container at at least two discrete locations on the inner wall of the container.

[0013] Alternatively, a reinforcing member including a reinforcing panel is provided, the reinforcing panel being connected to one or more reinforcing members suspended from the inside of the cover member, the reinforcing panel being arranged spaced apart from and substantially parallel to the cover member.

[0014] Alternatively, the reinforced panel is a shielded panel.

[0015] Optionally, the reinforcing panel includes a peripheral edge configured to form the inner wall of the friction-engaging container.

[0016] Optionally, the outer edge of the cover member is reinforced, for example by thickening the area or the outer band.

[0017] Optionally, the outer edges of the reinforcing panel members are reinforced, for example, by thickening the area or the outer strip.

[0018] Advantageously, the edgeless lid according to the invention is configured such that the interlocking engagement with the container occurs only inside the container. Therefore, interlocking engagement can occur inside the container and between any one or more reinforcing members and / or between the outer edges of the lid members.

[0019] Therefore, the rimless lid structure can be installed substantially inside the container, with the lid member essentially flush with the container's rim when the lid is attached. The rimless lid structure is securely attached to the container via frictional engagement between the lid member and / or reinforcing members and the container's inner wall. This eliminates the need for curved rims or upright and / or overhanging skirts around the outer edge of the lid to clamp or fit onto the container's opening / rim. For aesthetic and hygienic reasons, the outer side of the lid member may extend or cross over the top of the container opening.

[0020] Alternatively, the lid component is substantially flat. Therefore, if the lid has a drinking hole in the lid component, less container tilting is required during drinking compared to when the lid surface is raised above or recessed below the container rim.

[0021] Preferably, the rimless lid is made of a biodegradable, recyclable, or compostable material, such as paper, cardboard, corrugated cardboard, plant starch, or other suitable plant-based materials. The application of this invention can be extended beyond paper lids to include lids made of plastic and other materials. Therefore, alternatively, for example, the lid could be made of PET plastic for recyclable PET plastic cups. Alternatively, other materials can be used.

[0022] The rimless lid is suitable for use with containers that hold (1) viscous contents, such as soup, porridge, or noodles; (2) solid foods, such as fries or popcorn; and (3) hot and / or cold drinks, such as coffee, tea, soda, beer, etc., but are not limited thereto.

[0023] The end edges of one or more reinforcing members (including reinforcing panels) are preferably configured to conform closely to the container wall and / or deform the container wall (where the container material can be deformed by one or more reinforcing members), thereby securely holding the flangeless lid in place and imparting rigidity to the flangeless lid / container assembly. One or more reinforcing members may also provide structural support and rigidity for the lid itself. One or more reinforcing members may also provide structural support and rigidity for the container.

[0024] In one arrangement, at least one reinforcing member, preferably a suspended reinforcing member, extends through the inside of the lid member. This at least one reinforcing member preferably has a pair of opposing container engagement portions located at opposite peripheral positions on the inside of the lid member, such that when the rimless lid is placed on top of the container opening, the at least one suspended reinforcing member enters the container, and the container engagement portions rub against the inner wall of the container at opposite peripheral positions on the container wall. In this way, the rimless lid can be secured to the container.

[0025] Optionally, each or every reinforcing member has at least two discrete locations on the inner wall of the container in frictional contact with the inner wall of the container.

[0026] In an optional arrangement, at least two such reinforcing members are provided, each reinforcing member being provided across the inside of the cover member. The at least two reinforcing members may cross or intersect each other.

[0027] In a further alternative arrangement, at least two reinforcing members do not intersect. Alternatively, the non-intersecting reinforcing members are substantially or generally parallel to each other.

[0028] A variety of other alternative arrangements to achieve the required level of friction are also possible and conceivable.

[0029] In an alternative arrangement, the at least one reinforcing member is configured to engage the inner wall of the container at multiple discrete locations. For example, the reinforcing member may comprise three parts, arranged in a “Z” shape when viewed in a plan view, and configured to engage the inner wall of the container at four discrete locations. It should be understood that other alternative arrangements are also possible to provide the required number of discontinuous contact points to achieve the desired degree of frictional engagement between the flangeless lid and the container.

[0030] In an arrangement where reinforcing members intersect or cross each other, suitable interlocking slots or other openings can be made in the respective reinforcing members so that they can cross each other during assembly. Through their intersection and interlocking, the reinforcing members can structurally strengthen and reinforce each other and the entire flangeless cover structure.

[0031] Alternatively, one or more reinforcing members of the edgeless cover may include one or more ribs.

[0032] Alternatively, one or more reinforcing members may be integrally formed with the cover member.

[0033] Alternatively, the cover member of the edgeless cover may be formed from a flat sheet of material (e.g., cardstock) and folded along a predetermined line to form the or each reinforcing member as a rib.

[0034] Alternatively, for example in the case of a flangeless cover formed by molding, one or more ribs may be integrally molded with the cover component.

[0035] Alternatively or additionally, the reinforcing member may be formed as a second rib from the cover member or another flat sheet and attached (e.g., by adhesive, welding or other suitable method) to the inside of the cover.

[0036] Optionally, one or more reinforcing members can move between an open and collapsed state. In the open state, one or more reinforcing members protrude from the inside of the lid member, so the lid can be used to close the container. When one or more reinforcing members collapse, one or more reinforcing members move closer to the lid member, preferably flush with the lid member. This arrangement allows multiple lids to be stacked and stored while minimizing the storage space required to store the lids.

[0037] In an alternative arrangement where the reinforcing members intersect each other, the cooperating openings in the first and second reinforcing members can be configured such that the first and second reinforcing members intersect each other during assembly, allowing the first and second reinforcing members to move relative to each other and to hinge relative to the lid during movement between open and collapsed states. In one arrangement, each of the first and second reinforcing members has a fold line or hinge line near the lid. When the first and second reinforcing members move from an open state to a collapsed state, for example, by an external force applied to them by a user, the first and second reinforcing members are allowed to hinge relative to the lid about their respective hinge lines, thereby moving closer to the lid. To bring the first and second reinforcing members into the open state, for example by an external force applied by a user, the first and second reinforcing members pivot in opposite directions about their respective hinge lines, i.e., away from the lid, until the first and second reinforcing members protrude from the inside of the lid. Preferably, the interaction between the reinforcing members allows them to be securely engaged and held in place by, for example, suitable cooperating grooves, to hold them securely in the open position.

[0038] In an optional arrangement where there is a single reinforcing member or the reinforcing members do not intersect each other, the reinforcing member may be foldable or collapseable relative to the cover to a flat state, and may move between the folded / collapsed state and the unfolded or open state.

[0039] Alternatively, when in the open position, the reinforcing member can be secured in the open position by fastening arrangements.

[0040] Suitable fastening arrangements can take many possible forms.

[0041] Optionally, in one arrangement, the fastening arrangement includes a movable tab or clip arrangement, wherein the movable tab or clip is a cut-off portion of the reinforcing member that is pushed from a closed position to an open position and forms an angle of approximately 90 degrees along a portion of the reinforcing member to prevent the reinforcing member from collapsing and to prevent the lid from moving closer together and folding back to the collapsed / folded position. Once pushed into the open, fixed position, reverse movement of the fastening tab or clip can be prevented by forming a stop (e.g., a raised line or crease in the lid) at a preferred holding position, configured to prevent the movable tab or clip from moving back to its initial position.

[0042] The container may have a circular, rounded rectangular, or other shaped rim. The rimless lid may be a shape that generally fits the shape of the container. An advantageous arrangement is that the shape of the container or its rim and the shape of the rimless lid differ slightly to increase friction between the container and the rimless lid and to make the closure more secure. For example, in the case of a container with a circular rim, the rimless lid may be elliptical. In this case, when the rimless lid closes the container, at least one reinforcing member frictionally engages the inner wall of the container and deforms it (where the material of the container can be deformed by at least one reinforcing member) to present the elliptical shape of the rimless lid, thereby strengthening the contact between the container and the rimless lid, making the closure more reliable, increasing the rigidity of the rimless lid / container assembly, and increasing the structural strength and robustness of the container for retention, etc.

[0043] As described above, in the example, the edgeless cover may include a reinforcing member in the form of a panel, which is disposed on the inside of and spaced apart from the cover member.

[0044] Optionally, the reinforcing panel is separated from the inside of the cover member by one or more reinforcing members.

[0045] Alternatively, the reinforced panel is a shielded panel.

[0046] It should be understood that in this instruction manual, the terms "reinforced panel" and "shielded panel" are synonymous and interchangeable.

[0047] The size and shape of the reinforcing panel can be designed so that its outer edges fit snugly against the inner wall of the container. This provides additional rigidity to the rimless cap / container assembly and makes container handling safer. For example, the reinforcing panel can be shaped to closely match the planar shape of the container wall at the height of the reinforcing panel inside the container when the rimless cap is placed on it. The reinforcing panel can also be elliptical if the container rim is rounded and the rimless cap is elliptical. In the latter case, when the rimless cap closes the container, the outer edges of the reinforcing panel engage and cause the container wall to deform (if the container material can shield the panel from deformation), resulting in the elliptical shape of the reinforcing panel, thus increasing the rigidity of the cap / container assembly. While providing rigidity to the rimless cap / container assembly, the fit of the reinforcing panel securely holds the rimless cap to the container, keeping the cap firmly attached to the beverage container while preventing leakage. Furthermore, the reinforcing panel keeps the contents of the container away from the inside of the cap member of the rimless cap and the rim of the container.

[0048] Optionally, the shielding panel is planar. The shielding panel can be formed from a single sheet of material or a molded material.

[0049] A shielding panel may include reinforcing, raised, or thickened areas (all or in multiple locations) around its periphery or periphery edge. Such raised areas can be created by various methods, such as applying a curl to the periphery of the shielding panel (similar to the curl used around the rim of a disposable beverage cup). Alternatively, the periphery can be thickened or reinforced by another method, or a separate, generally circular strip can be attached to the periphery of the shielding panel by adhesives, welding, or other methods. In the case of a molded shielding panel, the shape of the mold can be adjusted to provide a reinforced area around the periphery of the shielding panel.

[0050] The main purpose of the raised or thickened area around the shielding panel is to increase the structural strength of the shielding panel and increase the level of friction between the shielding panel and the inner wall of the container during use, thereby making the closure friction between the lid and the container more secure and safe.

[0051] The shielding panel may include suitable reinforcing members spanning a planar area to give the shielding panel additional structural strength. This reinforcement can be achieved in several ways, such as by adding one or more reinforcing strips or ribs.

[0052] As described above, the shielding panel can be attached to the inside of the cover member by one or more reinforcing members. In this way, one or more reinforcing members of various alternative examples act as connectors connecting the cover member and the shielding panel, and also act as spacers that keep the shielding panel spaced apart from the cover member.

[0053] In an example where one or more reinforcing members are collapsible, when in the open state, the reinforcing members keep the lid member and the shielding panel spaced apart from each other, such that the combined structure of the lid member, reinforcing members, and shielding panel closes the beverage container. When one or more reinforcing members are in the collapsed / folded state, the lid member and the shielding panel move together to reduce or eliminate the space between them. This collapsed / folded arrangement allows multiple edgeless lids to be stacked and stored in a flat packaging structure while minimizing the storage space required to store the lids.

[0054] The open position of the cover and shielding panel can be securely held in place by a fastening device. This fastening device can be released by the user, allowing the cover and shielding panel to return to their collapsed / folded position.

[0055] Depending on the construction of the reinforcing member, the fastening arrangement can take many forms.

[0056] In a configuration where the reinforcing members do not intersect each other but are completely or partially parallel or have a “Z” configuration, the fastening arrangement may include movable tabs or clips, wherein the tabs or clips are pushed from a closed position to an open position and form an angle of approximately 90 degrees along a portion of the reinforcing member, preferably on each reinforcing member. This prevents the reinforcing members from collapsing and prevents the cover and shielding panel from moving close together and folding back to the collapsed / folded / flattened packaging position.

[0057] Once pushed into the open, fixed position, reverse movement of the fastening tab or clip can be prevented by a stop, such as a raised line or crease at a preferred holding position in the cover member and / or shielding panel, which is configured to prevent the fastening tab or clip from moving back to its initial position.

[0058] In a construction where reinforcing members intersect or cross each other (optionally at a 90-degree angle), the fastening arrangement can be a hinge-like structure.

[0059] One or more reinforcing members may be in the form of first and second ribs as described above. In this arrangement, the first rib is preferably permanently attached to or formed together with one of the cover member and the shielding panel. The second rib is preferably permanently attached to one or both of the cover member and the shielding panel, or formed together with one or both of the cover member and the shielding panel, and releasably attached to the other of the cover member and the shielding panel. The second rib can be releasably attached to the cover member and the shielding panel by suitable fastening arrangements. The fastening arrangements prevent the first and second ribs from collapsing. The fastening arrangements may include, for example, tabs provided on the second rib and grooves formed in the cover or shielding panel, regardless of which the second rib is releasably attached to. In the open state of the first and second ribs, the tabs engage in the grooves and prevent the second rib from hinged relative to the cover member or the shielding panel, regardless of which the second rib is attached to. In this arrangement, the first rib has a pair of first hinge lines, one near the cover member and the other near the shielding panel, and the second rib has a second hinge line near the cover member or the shielding panel, regardless of which the second rib is attached to. When the first and second ribs move from the open state to the collapsed state, for example, by the user applying external force to the cover member and shielding panel to push them towards each other, the fastening arrangement separates (or, in a particular arrangement, the tab of the second rib disengages from the slot), and the second rib disengages from either the cover member or the shielding panel, whichever is fastened to by the fastening arrangement. Simultaneously, the first rib is allowed to hinge relative to the cover member and the shielding panel about a first hinge line, and the second rib is allowed to hinge relative to the cover member or the shielding panel about a second hinge line, whichever is attached to. When both the first and second ribs are hinged about their respective first and second hinge lines, the cover member and the shielding panel move closer together, and the space between them decreases or disappears. To return the first and second ribs to the open state, the user applies force to the cover member and the shielding panel to separate them, and repeats the above steps in reverse order. As the second rib returns to its open position, the fastening arrangement engages (or, in certain arrangements, the tabs of the second rib engage the slots) and the second rib engages the cover member or shielding panel, whichever the second rib is fastened to via the fastening arrangement, thereby securing the second rib and the entire assembly in the open position. Alternatively, the ribs may interlock in a substantially similar manner.

[0060] The shielding panel (i.e. the reinforced panel) may include vents or cutouts of appropriate size and location to allow the release of pressure from the accumulation of vapors or gases generated by the hot contents or the gaseous contents.

[0061] The secure hold and clamping of the lid to the container can be enhanced by creating raised lines or creases on the inner wall of the container, surrounding all or part of the container wall just below where the shielding panel contacts the container's inner wall. The shielding panel is effectively clamped below the raised lines or creases, helping to secure the shielding panel in its optimal holding position and helping to prevent the shielding panel from loosening its contact with the container.

[0062] Holes can be formed in the lid component to allow drinking, pouring liquids, or removing solid food from the container without having to remove the lid from the container.

[0063] The drinking hole can be curved and shaped to allow the consumer's lips to make full, direct, and unobstructed contact with the rim of the beverage container, so that the consumer can drink directly from the container, rather than through a closed hole on the lid. This feature greatly enhances the consumer's drinking experience.

[0064] In one arrangement, the edgeless cover may include a baffle formed in the cover member and initially blocking the opening. The cover member may also include a weakened region provided by, for example, serrations, perforations, or thinning of the cover material, which defines the baffle and allows the baffle to be torn off to open the opening, while the cover, together with the baffle, provides a fully sealed closure until opened.

[0065] In the second arrangement, the baffle can be repeatedly opened and securely closed between consumption intervals to prevent splashing or overflowing from the container. For user convenience, the baffle can be configured together with the lid to remain fixed in the open or closed position.

[0066] In conjunction with the drinking hole, a flow deflector arrangement can be provided on the inner side of the cover member adjacent to the drinking hole. The flow deflector arrangement is preferably configured to prevent liquid contained in the container, especially easily splashable aqueous liquids, from splashing directly upwards through the drinking hole when the container is in a generally upright orientation. The flow deflector arrangement is also preferably configured to allow liquid to approach the drinking hole laterally or indirectly, such that the liquid loses most of its energy / momentum upon reaching the drinking hole, thereby reducing the likelihood and intensity of accidental spillage or splashing when drinking from or pouring from the container. In one arrangement, the flow deflector arrangement includes a portion substantially disposed in front of the drinking hole to deflect splashed liquid or prevent it from flowing directly into the drinking hole.

[0067] In one arrangement, the aforementioned shielding panel is suitable for use as a flow deflector arrangement.

[0068] Therefore, in one possible arrangement, the shielding panel may have one or more cutouts near the drinking port to define a flow opening. These cutouts may define the flow opening together with the inside of the container.

[0069] During drinking, when the container is tilted, the liquid will flow through the flow opening and into the drinking hole. When the container is upright, the shielding panel prevents splashes caused by shaking the container from reaching the drinking hole.

[0070] In the second arrangement, the flow opening may include a cutout located entirely within the periphery of the shielding panel but sufficiently close to the inside of the cover member, so as to allow easy flow from the container through the cutout when the container is tilted.

[0071] Before the lid is fitted into the cup, an intermediate well can be formed between the shielding panel and the second panel, which acts as a flow deflector to prevent direct splashing out of the container. The second panel lies flat on and above the shielding panel. The second panel is shaped to cover the sub-shielding panel in the area directly below the drinking hole and is not fixed or glued to the shielding panel in this position. The outer edge of the second panel extends further than the outer edge of the shielding panel. Therefore, when the lid is fitted into the container, the contact with the inner wall of the container causes the second panel to separate from the shielding panel, creating the intermediate well or essentially enclosed space. When the container is tilted, one or more cutouts on the shielding panel will allow liquid to flow from the container into the intermediate well. When the container is tilted, one or more cutouts in the second panel will allow liquid to flow out of the intermediate well for drinking. The cutouts in the shielding panel and the second panel are positioned far apart from each other and not opposite each other, so that liquid cannot splash directly into, through, and out of the intermediate well in a straight line. This structure facilitates drinking or pouring from the container with a smooth motion and flow of liquid, while preventing splashing.

[0072] Preferably, the container is a cup. The shape of the cup will vary depending on the nature of the contents, for example, whether the contents are a beverage to be drunk directly or poured from the container, a viscous food such as soup to be scooped or poured from the container, or a solid food to be removed or poured from the container.

[0073] The edgeless cap described in this article can be used for both disposable and reusable caps.

[0074] It should be understood that the features of the above embodiments can be combined with other embodiments where appropriate, and / or in fact form novel and inventive aspects by virtue of their own rights. Attached Figure Description

[0097] In the accompanying drawings, the flangeless lids according to the invention are generally designated by reference numerals 10, 97, and 99. First, the common features of the flangeless lids 10, 97, and 99 will be described. For brevity, the same reference numerals are used to denote common features. The flangeless lids 10, 97, and 99 include a lid member having an outer side 1, an inner side 3, and a peripheral edge 5. The flangeless lids 10, 97, and 99 are adapted to be fixed to the inner wall of a container 900 (see...). Figure 21-27 The flangeless lids 97, 99 are designed to be securely attached to the inner wall of the container, as described below. The flangeless lids 10, 97, 99 are preferably made of recyclable, biodegradable, or compostable materials, such as paper, cardboard, corrugated cardboard, plant starch, or other suitable plant-based materials.

[0098] At least one reinforcing member 130, 140, 530, 540, 630, 640 is provided on the inner side 3 of the cover member of the flangeless cover 10, 97, 99. The reinforcing member hangs from the inner side of the cover portion. The hanging reinforcing member 130, 140, 530, 540, 630, 640 may be referred to as a rib. The reinforcing member or rib 130, 140, 530, 540, 630, 640 is configured to frictionally engage the inner wall of the container, as described below.

[0099] The rimless lids 10, 97, and 99 are preferably suitable for containers of viscous fluids (e.g., soup). However, it is understood that rimless lids can also be used for containers of solid foods, as well as for containers of hot and / or cold beverages (e.g., coffee, tea, soda, beer, etc., but not limited thereto).

[0100] The reinforcing members / ribs 130, 140, 530, 540, 630, and 640 are adapted to fit snugly against the container wall and / or deform the container wall (where the container material can be deformed by the ribs 130, 140, 530, 540, 630, and 640). This securely holds the flangeless caps 10, 97, and 99 in place and imparts rigidity to the flangeless caps 10, 97, and 99 / container assembly. The ribs 130, 140, 530, 540, 630, and 640 also provide structural support and rigidity to the flangeless caps 10, 97, and 99 themselves.

[0101] like Figure 1 , 5 As shown in Figures 9 and 15, each rib 130, 140, 530, 540, 630, 640 extends through the inner side 3 of the cover member of the respective cover 10, 97, 99. Each edgeless cover 10, 97, 99 has at least one, but preferably a pair, of corresponding ribs 130, 140; 530, 540; and 630, 640. Ribs 130, 140; 530, 540; and 630, 640 may intersect or cross each other. Cooperating grooves 135, 145; 535, 545 and cutouts 670, 671 are formed in the corresponding ribs 130, 140; 530, 540; and 630, 640, such that ribs 130, 140; 530, 540; and 630, 640 may intersect each other during assembly. Alternatively, in this example, the ribs may not intersect.

[0102] like Figure 24 As shown in detail, each reinforcing member 130, 140, 530, 540, 630, 640 has a pair of opposing container joint portions 130a, 130b, 140a, 140b, 530a, 530b, 540a, 540b, 630a, 630b, 640a, 640b, which are located at opposing peripheral positions on the inner side 3 of the flangeless cover 10, 97, 99. When the lid members of the flangeless lids 10, 97, and 99 are placed on top of the container opening, the reinforcing members 130, 140, 530, 540, 630, and 640 enter the container, and the container mating portions 130a, 130b, 140a, 140b, 530a, 530b, 540a, 540b, 540b, 630a, 630b, 640a, and 640b rub against the inner wall of the container. In this way, the flangeless lids 10, 97, and 99 are secured to the container.

[0103] exist Figures 1 to 7 In the example, the edgeless covers 10, 97 are formed from a flat sheet of material (e.g., cardstock) and folded along predetermined lines to form the first ribs 130, 530. Figures 8 to 17 In the example, the first rib 630 is formed from a single flat sheet and attached (e.g., by adhesive, welding or another suitable method) to the inside 3 of the cover member of the cover 99.

[0104] exist Figures 1 to 3 and Figures 8 to 17 In the example shown, the second ribs 140, 640 are formed from another flat sheet and attached (e.g., by adhesive, welding or other suitable method) to the inner side 3 of the cover member of the cover 10, 99. Figures 4 to 7 In the example, the second rib 540 is formed as part of the reinforcing member of the shielding panel 550 (described in more detail below). Like the edgeless cover 97, the shielding panel 550 is formed from a flat sheet and folded along a predetermined line to form the second rib 540.

[0105] exist Figures 1 to 3 and Figures 8 to 17 In the example, stiffeners / ribs 130, 140, 630, and 640 can move between an open and collapsed state. In the open state (see...) Figure 1 , 8 Ribs 130, 140, 630, and 640 protrude from the inner side 3 of the lid members of lids 10 and 99, thus lids 10 and 99 can be used to close containers. When ribs 130, 140, 630, and 640 collapse (see...), Figures 12 to 16 Ribs 130, 140, 630, and 640 move close to, and preferably flush with, the cover members of lids 10 and 99. This arrangement allows multiple edgeless lids 10 and 99 to be stacked and stored while minimizing the storage space required to store edgeless lids 10, 97, and 99. The cooperating slots 135 and 145 and cutouts 670 and 671 in the respective ribs 130, 140, 630, and 640 are configured such that the respective ribs 130, 140, 630, and 640 intersect each other during assembly and allow the ribs 130, 140, 630, and 640 to move relative to each other and to the cover members of lids 10 and 99 during movement between open and collapsed states.

[0106] exist Figures 1 to 3 and Figures 8 to 17In the example, each rib 130, 140, 630, 640 has a corresponding hinge line 175, 177, 675, 677 adjacent to the corresponding cover member. When the ribs 130, 140, 630, 640 move from an open state to a collapsed state, for example by an user applying an external force to the ribs 130, 140, 630, 640, the ribs 130, 140, 630, 640 are allowed to hinge relative to the cover member about their respective hinge lines 175, 177, 675, 677, thereby moving closer to the cover member. To bring the ribs 130, 140, 630, 640 into the open state, for example by an user applying an external force, the ribs 130, 140, 630, 640 are moved in opposite directions, such as... Figure 18 As shown in the example, away from the edgeless covers 10, 99, pivot about their respective hinge lines 175, 177, 675, 677 until ribs 130, 140, 630, 640 protrude from the inside 3 of the covers 10 / 99.

[0107] The lid members of the rimless lids 10, 97, and 99 can generally be circular or elliptical in planar shape. In the described example, the rimless lid is elliptical to provide stronger contact between the container and the rimless lid 10, 97, and 99, although the invention is not limited to this particular shape. Elliptical rimless lids are particularly useful when closing containers with rounded tops. When the rimless lids 10, 97, and 99 close the container, the ribs 130, 140, 530, 540, 630, and 640 frictionally engage the inner wall of the container and deform it (where the material of the container can be deformed by the ribs 130, 140, 530, 540, 630, and 640), and present the elliptical shape of the lids 10, 97, and 99, thereby increasing the rigidity of the lid 10, 97, and 99 / container assembly.

[0108] In such Figure 28 In the example shown, in an alternative arrangement, at least one reinforcing member is configured to engage the inner wall of the container at multiple discrete locations. For example, reinforcing member 700 may include three portions 700A, 700B, and 700C, which, when viewed in a plan view, are arranged, for example, in a “Z” configuration, with their respective end edges and corners 701, 702, 703, and 704 each configured to engage the inner wall of the container at discrete locations. It should be understood that other alternative arrangements are possible to provide the required number of discontinuous contact points to achieve the desired degree of frictional engagement between the flangeless cap and the container.

[0109] exist Figures 4 to 17In the example, reinforcing members in the form of shielding panels 550, 650 are disposed on the inner side 3 of the respective cover members 97, 99. The shielding panels are connected to one or more reinforcing members that dangle from the inner side of the cover members, and the reinforcing panels are arranged spaced apart from and substantially parallel to the cover members. The reinforcing panels include a peripheral edge configured to frictionally engage the inner wall of the container.

[0110] like Figure 21 As shown, the dimensions and shape of the shielding panels 550 and 650 ensure that their outer edges fit snugly against the inner wall of the container. This provides additional rigidity to the flangeless caps 97 and 99 / container assembly and makes container handling safer. The shielding panels 550 and 650 can be shaped such that when the flangeless caps 97 and 99 are placed on the container, their outer edges closely match the planar shape of the container wall at the height of the shielding panels 550 and 650 within the container. Figures 4 to 17 In the example, the shielding panels 550 and 650 are elliptical. Therefore, when the flangeless caps 97 and 99 close the container, the outer edges of the shielding panels 550 and 650 cause deformation of the container wall (where the container material can be deformed by the shielding panels 550 and 650) and present the elliptical shape of the shielding panels 550 and 650, thereby increasing the rigidity of the flangeless caps 97 and 99 / container assembly. While imparting rigidity to the flangeless caps 97 and 99 / container assembly, the fit of the outer edges of the shielding panels 550 and 650 securely fastens the flangeless caps 97 and 99 to the container, ensuring that the caps 97 and 99 are firmly held on the beverage container while preventing leakage. Furthermore, the shielding panels 550 and 650 keep any potential splashing of the container contents away from the inner side 3 of the caps 97 and 99 and the rim of the container.

[0111] In some variations, the rimless caps 10, 97, 99 may optionally include a drinking hole 7 in the cap member, allowing the rimless caps 10, 97, 99 to be used for drinking. For example... Figure 1 , Figure 2 , Figures 4 to 5a , Figure 8 , Figure 9 and Figures 15 to 17 As shown, the rimless caps 10, 97, 99 may include a baffle 57 formed in the cap member that initially closes the drinking hole 7. The rimless caps 10, 97, 99 may also include a weakened region 507, provided by, for example, perforation or thinning of the cap material. The weakened region defines the baffle 57 and allows the baffle 57 to be torn off to open the drinking hole 7. Before opening, the cap member of the rimless caps 10, 97, 99, together with the baffle 57, provides a completely sealed closure.

[0112] like Figure 30As illustrated in the example, a drinking hole 70 can be formed in a lid member that is bent and / or shaped to allow the consumer's lips to make full, direct, and unobstructed contact with the edge 901 of the beverage container 900, allowing the consumer to drink directly from the container rather than through a closed hole in the lid. This hole 70 can be defined by a segment with a curved or arcuate chord 71 that is cut from or otherwise removed from the peripheral edge 5 of the rimless lid member. This relatively long portion of the hole 70, exposing the container rim 901, greatly enhances the consumer's drinking experience.

[0113] In a variation of the drinking hole 7, flow deflector arrangements 500 and 600 are located on the inner side 3 of the cap members 97 and 99 adjacent to the drinking hole 7. The flow deflector arrangements 500 and 600 are configured to prevent liquid contained in the container, especially easily splashable aqueous liquids, from splashing directly upwards through the drinking hole 7 when the container is in a generally upright orientation. The flow deflector arrangements 500 and 600 are also configured to allow liquid to approach the drinking hole 7 laterally or indirectly, such that the liquid loses most of its energy / momentum upon reaching the drinking hole 7, thereby reducing the likelihood and intensity of accidental spillage or splashing when drinking from or pouring from the container.

[0114] The flow deflector arrangement includes a portion substantially positioned in front of the drinking port 7 to deflect splashed liquid or prevent it from flowing directly into the drinking port 7. Figures 4 to 17 In the examples described above, the reinforcing members in the form of shielding panels 550 and 650 are suitable for use as corresponding flow deflector arrangements 500 and 600. For this purpose, the shielding panel includes one or more openings located near the drinking hole 7 to define a flow opening 21 together with the inner side 3 of the flangeless cap members 97 and 99. The opening can be as follows: Figure 4 The example shown in the image has one or more cutouts 551 at the outer edge of the shielding panel, or as shown in the image. Figure 8A The example shown is in the form of one or more holes 551A provided in the shielding panel. During drinking, when the container is tilted, the liquid flows through the openings, such as between the cutout 551 and the container wall, or through the holes 551A in the shielding panels 550, 650, into the flow opening 21 and flows toward the drinking hole 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 hole 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 shielding panels 500, 600, thus providing a smoother flow through the drinking hole 7 during sip. When the container is in an upright position, the shielding panel reinforcement members 550, 650 prevent splashes from reaching the drinking hole 7.

[0115] As described above, the shielding panel reinforcing members 550 and 650 are connected to the inner side 3 of the cover members of the covers 97 and 99 via ribs 530, 540, 630, and 640. Ribs 530, 540, 630, and 640 act as connectors, connecting the cover members of the covers 97 and 99 and the shielding panels 550 and 650, as well as the spacers, to keep the shielding panels 550 and 650 spaced apart from the inner side 3 of the cover members.

[0116] exist Figures 4 to 7 In the example, the second rib 540 is formed as part of the shielding panel 550. Like the cover member, the shielding panel 550 can be formed from a single flat sheet and folded along a predetermined line to form the second rib 540. During assembly, the ribs 530 of the cover member 97 and the ribs 540 of the shielding panel 550 engage with each other via slots 535, 545, thereby intersecting and connecting the cover member and the shielding panel 550.

[0117] As mentioned above, in Figures 8 to 17 In the example, reinforcing ribs 630 and 640 are movable between an open and a collapsed state. In the open state, reinforcing rib 630 keeps the cover member and shielding panel 650 spaced apart from each other, so that the cover 99 can be used to close the container (see...). Figure 8 , 9 When reinforcing ribs 630 and 640 collapse (see...) Figure 14 , 15 The cover member 99 and the shielding panel 650 move together, thereby reducing or eliminating the space between the cover member and the shielding panel 650. This arrangement allows multiple flangeless covers 99 to be stacked and stored while minimizing the storage space required to store the flangeless covers 99. Ribs 630 are attached to or formed together with each of the cover member and the shielding panel 650. Ribs 640 are attached to or formed together with the cover member and are releasably attached to the shielding panel 650 by a suitable fastening arrangement. The fastening arrangement prevents ribs 630 and 640 from collapsing. Figures 8 to 17 In the example, the fastening arrangement includes a tab 660 disposed on the rib 640 and a groove 661 formed in the shielding panel 650. For example... Figures 8 to 17As shown, in the open state of the reinforcing members / ribs 630, 640, the tab 660 engages in the groove 661 and prevents the rib 640 from hinged relative to the cover 99. The rib 630 has a pair of first hinge lines 675, one near the cover 99 and the other near the shielding panel 650. The rib 640 has a hinge 677 near the cover 99. When the ribs 630, 640, for example, are moved from the open state to the collapsed state by an external force applied to the cover 99 and the shielding panel 650 by a user to push the cover member of the cover 99 and the shielding panel 650 towards each other, the tab 660 disengages from the groove 661, and the rib 640 disengages from the shielding panel 650. Simultaneously, the rib 630 is allowed to hinge relative to the cover 99 and the shielding panel 650 about the hinge line 675, and the rib 640 is allowed to hinge relative to the cover 99 about the hinge line 677. When the two ribs 630, 640 are hinged around their respective hinge lines 675, 677, the cover member and the shielding panel 650 move closer together, and the space between the cover 99 and the shielding panel 650 decreases or is eliminated. To return the ribs 630, 640 to the open state, the user applies force to the cover member and the shielding panel 650 to separate them, and repeats the above steps in reverse order. At the end of the rib 640's return to the open state, the tab 660 engages the groove 661, and the rib 640 engages the shielding panel 650, thereby securing the rib 640 and the entire assembly in the open state.

[0118] exist Figure 18 , 19 In the example shown in 20, the reinforcing members do not intersect each other, but rather do not cross each other, for example, as shown in 20. Figure 29 Examples show basic or partial parallelism of 710, 720, or as... Figure 28 The example shown, a "Z"-shaped structure 700, can provide means for holding the reinforcing member in an open state. This means may include movable tabs or baffles, thereby providing tab / baffle formations 800, optionally extension formations, at one or both ends of the reinforcing member, which can be positioned from a closed position. Figure 19 Move to the open position ( Figure 20 (), forming an angle of approximately 90 degrees along the cross-section of the reinforcing member, preferably on each reinforcing member, it is wedged between the inner side 3 of the cover member and the shielding panel to prevent the corresponding reinforcing member from collapsing, and the cover member and the shielding panel move closer together and fold back as Figure 18 The collapsed / folded / flattened packaging location is shown. It is understood that the movable tabs may be positioned elsewhere along the reinforcing member, rather than at the ends.

[0119] Once the movable tab or baffle formation is pushed into the open, fixed position between the cover member and the shielding panel, unwanted reverse movement can be prevented by a suitable stop formation, such as a raised line or crease 801 at a preferred holding position on the cover member and / or shielding panel, which is configured to grip the baffle 800 and prevent it from moving out of the engagement between the cover member and the shielding panel.

[0120] like Figure 22 As shown, the outer edge 552 of the shielding panel reinforcing members 550 and 650 can be rolled up 553 to increase the rigidity of the shielding panel.

[0121] like Figure 23 As shown, the shielding panel reinforcing members 550 and 650 may be provided with a supplementary layer 554 to increase the rigidity of the shielding panel. The supplementary layer may include any suitable material or structure.

[0122] like Figure 24 As shown, the flangeless lid structure according to the invention can be substantially installed inside a container, with the lid member 99 substantially flush with the frame 901 of the container 900 when the lid is installed thereon. The flangeless lid structure is securely attached to the container by frictional engagement between the lid member and / or one or more reinforcing members and the inner wall of the container. This eliminates the need for curved edges or upright and / or overhanging skirts around the outer edge 5 of the lid for clamping or fitting onto the opening / edge of the container. For aesthetic and hygienic reasons, such as Figure 21 , 22 As shown in Figures 23, 24, 26, and 27, the outer side 1 of the lid cap component can extend or cross the top of the container opening. Figure 25 As shown, the outer edge 5 of the cover member can be located substantially inside the container rim, near the upper edge of the container rim.

[0123] Reference Figure 26 and 26 In the example of the rimless cap, before the rimless cap is assembled into the container, an intermediate well 1000 can be formed between the shielding panels 550, 650 and the second panel 1100. This intermediate well 1000 acts as a flow deflector to prevent direct splashing out of the container 900. The second panel 1100 is configured such that its plane abuts against and is positioned above the reinforcing panels 550, 650. The second panel 1100 is shaped to cover the reinforcing panels 550, 560 in the area directly below the drinking holes 7, 70, and is not fixed or bonded to the reinforcing panels in this position. The peripheral edge 1200 of the second panel 1100 extends slightly further than the peripheral edge 552 of the reinforcing panels 550, 560. Therefore, when the rimless cap is assembled into the container 900, the contact with the inner wall of the container causes the second panel 1100 to separate from the reinforcing panels 550, 650, creating the intermediate well 1000 or a substantially enclosed space. When the container is as follows... Figure 27 When tilted, one or more cutouts in the reinforcing panels 550, 650 allow liquid to flow from container 900 into intermediate well 1000. When container 900 is tilted, one or more cutouts 1300 in the second panel 1100 allow liquid to flow out of intermediate well 1000 for drinking. The corresponding cutouts in the reinforcing panels 550, 560 and the second panel 1100 are positioned far apart and not opposite each other, i.e., staggered, so that liquid cannot splash directly into, through, and out of intermediate well 1000 in a straight line. This arrangement facilitates drinking or pouring from container 900 with a smooth motion and liquid flow, while preventing splashing.
