[0017] In accordance with embodiments of the present invention, gasket systems are provided to facilitate the removable insertion and retention of an inner container within an outer container while providing resistance to rotational movement. In some aspects, the gasket may be particularly suited for use with glass inner containers and metal or insulated outer containers, though the principles described herein may be applied to various container materials and configurations.

[0018] The gasket system addresses several challenges associated with conventional container assemblies. In some cases, prior gasket designs may require excessive insertion force, may allow unwanted rotation of the inner container relative to the outer container, or may be difficult to clean and maintain. The gasket design described herein can provide ease of insertion, secure retention, rotational resistance, and user convenience.

[0019] In some implementations, the gasket includes a ring structure with a plurality of protrusions extending from its outer surface. These protrusions may be oriented substantially parallel to the vertical axis of the ring, creating a distinctive profile that interacts with the inner wall of the outer container. The geometry and arrangement of these protrusions may be selected to achieve desired insertion forces, removal forces, and anti-rotation characteristics.Attorney Docket: 0655-0849-0WO

[0020] The gasket may also include a lip or flange structure that serves multiple functions, including positioning the gasket within the container assembly, providing a gripping surface for users, and creating a seal to prevent material from entering the space between the inner and outer containers. In some aspects, the gasket components can be configured for easy cleaning and can be compatible with dishwasher cleaning processes.

[0021] The following detailed description provides various implementations and features of the gasket system and functional characteristics that may be employed individually or in combination.

[0022] Referring to FIGS. 1 and 2, a gasket 10 (or gasket design) is shown where a gasket ring 12 is configured to fit around a glass insert / container 1 and includes a plurality of V-shaped (or Vertically disposed) protrusions 14A (FIGs 1 and 2) positioned around an outer circumferential perimeter of the gasket 10, and in one implementation includes a lip 16 configured to engage between a top edge of an outer container, and a portion of the glass insert / container 1. Contrary to the use of horizontal protrusions found on gaskets of the prior art, the vertical or V-shaped protrusions 14 make it easier to insert the inner glass container 1 into the outer vessel 2 as they travel in the vertical or axial direction of the inner glass container and the outer container 2. In addition, the V-shaped protrusions operate to limit and / or prevent entirely the rotation of the inner glass insert / container within the outer container. By using the V-shape for the gasket protrusions, when the glass insert / container 1 is rotated with respect to an outer container 2 (e.g., see FIGS. 4 and 5), half of the V angled protrusion will bind or jam in one direction (e.g., clockwise) and the other half will bind or jam in the opposite direction (e.g., counterclockwise).

[0023] The gasket ring 12 can be formed from a flexible, resilient material such as silicone, rubber, thermoplastic elastomer, or other suitable polymeric materials that can withstand repeated insertion and removal cycles while maintaining their structural integrityAttorney Docket: 0655-0849-0WOand sealing properties. A ring portion 15 of the gasket ring 12 can be configured with a thickness and width selected to provide adequate structural support while allowing for sufficient flexibility during installation. In some aspects, an inner surface of the ring portion 15 may be smooth or may include surface features designed to enhance grip on the glass inner container 1. An outer surface of the ring portion 15, which carries the V-shaped protrusions 14, can be configured to interface with the inner wall of an outer container.

[0024] The V-shaped protrusions 14 extend radially outward from the outer surface of the ring portion 15 and are oriented such that their longitudinal axes run substantially parallel to a vertical axis of the ring portion 15. In some cases, the V-shaped protrusions 14 may be evenly spaced around the circumference of the ring portion 15 to provide balanced contact with the outer container. The number of V-shaped protrusions 14 can vary depending on a diameter of the gasket 10 and a desired level of friction and rotational resistance. In some examples, implementations may include protrusions distributed unevenly around the gasket's circumference.

[0025] Each V-shaped protrusion 14 can include two angled surfaces that extend from an apex or ridge of the ring portion 15. The angle formed by these surfaces creates the V-profile when viewed in cross-section perpendicular to the vertical axis. This geometry permits the V-shaped protrusions 14 to flex and compress during insertion of the inner container into the outer container, while providing resistance to rotational movement once installed.

[0026] A height or radial extension of the V-shaped protrusions 14 from the outer surface of the ring portion 15 can be selected based on a gap between the inner container and outer container, as well as the desired insertion force and retention characteristics. In some implementations, the protrusions may extend between, e.g., 0.5 mm and 5 mm from the outer surface of the ring portion 15, though other dimensions may be suitable depending on the specific application.Attorney Docket: 0655-0849-0WO

[0027] The lip 16 positioned around a top of the ring portion 15 can extend radially inward, radially outward, or both to create a flange-like structure. This lip 16 can provide a seating surface that rests on an upper edge of the outer container when installed, helping to position the gasket 10 at the correct height within the assembly. The lip 16 may also provide a gripping surface for users during installation or removal of the inner container. In some cases, the lip 16 can include a sealing surface that contacts a shoulder or window portion of the inner container to create a seal that prevents debris or liquid from entering the space between the inner and outer containers.

[0028] When rotational force is applied to the inner container relative to the outer container, one angled surface of each V-shaped protrusion 14A can engage more firmly against the inner wall of the outer container, creating increased friction that resists the rotational movement. This anti-rotation feature can help prevent the inner container from spinning freely within the outer container during handling or use.

[0029] In some implementations, the V-shaped protrusions 14 can have varying dimensions around the circumference of the gasket 10. For example, some protrusions may have a larger V-angle while others have a smaller V-angle, or some protrusions may extend further radially than others. Such variations may be used to fine-tune the insertion force, removal force, and rotational resistance characteristics of the gasket assembly.

[0030] The material properties of the gasket may be selected to provide appropriate flexibility and durability, allowing for adequate compression of the V-shaped protrusions 14 during installation while maintaining sufficient structural integrity to resist deformation over time. The material may also be selected for temperature resistance, chemical resistance, and food safety compliance, particularly when the gasket is used in food or beverage container applications.Attorney Docket: 0655-0849-0WO

[0031] The V-shaped protrusions 14 can be formed integrally with the ring portion 15 during a molding process, or may be separately attached through bonding, welding, or mechanical fastening methods. In some aspects, each protrusion may have a substantially uniform cross-sectional profile along its vertical length, while in other implementations the cross-sectional dimensions may vary from the top to the bottom of the protrusion. End portions of each V-shaped protrusion 14 can be rounded or sharp, with the radius of curvature selected to balance between ease of insertion and rotational resistance.

[0032] The two angled surfaces forming each V-shaped protrusion 14A may be symmetrical or asymmetrical relative to a radial line extending from the center of the ring portion 15. In some cases, asymmetrical configurations may be employed to create directional insertion characteristics, where the gasket 10 slides more easily in one axial direction than the other. The angle between the two surfaces may range from, e.g., 20 degrees to 150 degrees, with angles between 30 degrees and 60 degrees being suitable for many applications.

[0033] The base of each V-shaped protrusion 14, where it connects to the outer surface of the ring portion 15, can include a fillet or radius to reduce stress concentration during flexing. This transition region can help prevent tearing or cracking of the gasket material during repeated insertion and removal cycles.

[0034] The ring portion 15 can have a circular, oval, or other closed-loop geometry matching the cross-sectional shape of the inner container. The wall thickness of the ring portion 15 can be substantially uniform or may vary around its circumference to accommodate manufacturing considerations or to provide localized reinforcement. In some implementations, the inner surface of the ring portion 15 can include one or more circumferential grooves or ribs that engage corresponding features on the outer surface of the inner container to enhance grip and prevent relative movement.Attorney Docket: 0655-0849-0WO

[0035] The lip 16 can extend from the top edge of the ring portion 15 at an angle relative to the vertical axis. In some cases, the lip 16 can be substantially horizontal, while in other implementations it may be angled upward or downward. The radial extent of the lip 16 provided sufficient surface area for seating against the outer container while not extending so far as to interfere with the overall assembly. The thickness of the lip 16 may be less than, equal to, or greater than the wall thickness of the ring portion 15.

[0036] In some implementations, the lip 16 can include one or more features on its upper or lower surface to enhance sealing or gripping performance. These features may include concentric ribs, radial ribs, textured surfaces, or localized raised or recessed regions. The underside of the lip 16, which may contact the upper edge of the outer container, may include a sealing bead or gasket feature that compresses when the assembly is fully installed to create a seal against ingress of materials.

[0037] The overall height of the gasket 10, measured from the bottom of the ring portion 15 to the top of the lip 16, can be selected based on the depth of engagement desired between the inner and outer containers. In some aspects, the gasket height can range from, e.g., 10 mm to 50 mm, though other dimensions may be appropriate for specific applications. The V-shaped protrusions 14 may extend along the entire height of the ring portion 15 or may be present only along a portion of the ring's height, such as the upper half or lower half. A lower portion of the V-shaped protrusions 14 can include a rounded or less severe surface to permit initial insertion between the inner and outer containers.

[0038] As will be appreciated, the gasket 10 can have different geometrical implementations depending on the friction and geometry of each application. In this regard, and referring to FIGS. 2 and 3, the angle a of the V of each protrusion 14a or 14b can be modified for a particular application. In addition, the length of extension of the protrusions 14 from aAttorney Docket: 0655-0849-0WOgasket ring 12 can also be modified to achieve desired friction and / or anti-rotational effects of the same.

[0039] Referring to FIGS. 4 and 5, there is shown an outer container 2 configured to receive the inner glass container 1 with gasket 10 in a place positioned under a shoulder 7 formed by a window 4. As will be appreciated, when inner glass container is positioned within the outer container 2, the lip 16 of the gasket ring 12 rests on an upper edge of the outer container 2 and is sandwiched between that upper edge and the shoulder 7 formed by the window portion 4 of the glass inner container 1.

[0040] The assembly shown in FIGS. 4 and 5 illustrates the relationship between the gasket 10, inner container 1, and outer container 2 in both pre-installation and installed configurations. In FIG. 4, the gasket may be positioned on the outer surface of the inner glass container 1 at a location below the shoulder formed by the window 4. The gasket 10 can encircle the inner container 1 with the V-shaped protrusions 14 extending radially outward, to engage with the inner wall of the outer container 2 during insertion. The lip 16 may be positioned to rest on the upper edge of the outer container 2 once the assembly is complete.

[0041] The inner glass container 1 can include a body portion having a first diameter and the window 4 having a second diameter that is larger than the first diameter, creating the shoulder where the two portions meet. This shoulder of the window 4 may provide a stop surface that limits the downward travel of the gasket along the outer surface of the inner container 1. In some aspects, the window 4 may be transparent or translucent, allowing visual inspection of the contents within the inner container 1. The body portion of the inner glass container 1 below the window 4 may have a substantially cylindrical shape, though other geometries such as tapered, conical, or polygonal cross-sections may be employed.

[0042] The outer container 2 can include a cylindrical or tubular wall defining an interior cavity sized to receive the inner container 1 with the gasket 10 installed thereon. TheAttorney Docket: 0655-0849-0WOinner diameter of the outer container 2 can be selected to provide a predetermined gap between the outer surface of the inner container 1 and the inner surface of the outer container 2, with this gap being bridged by the V-shaped protrusions 14 of the gasket 10. In some implementations, the outer container 2 can be formed from stainless steel, aluminum, plastic, wood or other suitable materials. The outer container 2 can include a single wall construction or may include double walls with an insulating space or vacuum between them.

[0043] During installation, the inner container 1 with gasket 10 can be inserted into the outer container 2 in a downward axial direction. As the V-shaped protrusions 14 contact the inner wall of the outer container 2, they may compress or deflect inward, allowing the assembly to slide into position. The vertical orientation of the protrusions 14 may facilitate this axial movement by providing relatively low resistance to sliding in the insertion direction. Once the gasket 10 reaches its final position, the lip 16 may come to rest on the upper edge or rim of the outer container 2.

[0044] In the installed configuration shown in FIG. 5, the lip 16 of the gasket 10 can be captured or sandwiched between two surfaces: the upper edge of the outer container 2 from below and the shoulder of the inner container 1 from above. This arrangement positions the gasket 10 at the correct height, preventing the gasket 10 from sliding downward into the gap between containers, and creating a seal that prevents debris or liquid from entering the space between the inner container 1 and the outer container 2. The compression of the lip 16 between these two surfaces may also contribute to the retention force that resists removal of the inner container 1 from the outer container 2.

[0045] The V-shaped protrusions 14, when installed, can be in contact with the inner wall of the outer container around the circumference of the gasket 10. In some cases, the protrusions 14 may be slightly compressed from their free state, creating a radial force that presses outward against the outer container wall. This contact pressure can provide friction thatAttorney Docket: 0655-0849-0WOresists both axial movement and rotational movement of the inner container 1 relative to the outer container 2. The V-shaped protrusions 14 form a line contact or narrow area contact with the outer container wall 2, concentrating the contact pressure to enhance the anti-rotation effect.

[0046] The gap between the inner container 1 and outer container 2 below the gasket may remain open. This gap may provide thermal insulation by creating a dead air space that reduces heat transfer between the contents of the inner container 1 and the external environment. The V-shaped protrusions 14 may span this gap while occupying only a small portion of the circumference, minimizing thermal bridging between the inner and outer containers.

[0047] In the examples provided in FIGS. 1-5, a food storage container is shown. It should be understood that various different outer containers such as hydration bottles and tumblers of all different shapes and sizes, with various drinking tops (e.g., straw, sipping lid) that can also benefit from the V-gasket design as presented herein.
