A drinking vessel may include a tumbler having an inner surface dimension, a first portion, and a second portion. The first portion may include a proximal surface having a first dimension and a first rim coupled to the proximal surface and having a second dimension, the first dimension being larger than the second dimension. The second portion may include a collar having an outer dimension substantially similar to the first dimension, an inner dimension substantially similar to the second dimension, and a second rim connected to the collar and having an outer dimension substantially similar to the second dimension and the inner surface dimension.

Various embodiments of a thin-walled metal container, such as a cup are described. The thin-walled metal cup includes a body with a tightly curled lip at the top end of the cup. The body includes a plurality of sections such that the diameter of the cup may be different at different places along the height of the cup. The thin-walled metal cup is designed to be light weight with a shape configured to facilitate grasping or holding the body of the cup.

Induction-heated vessels, and processes for manufacturing induction-heated vessels and vessel components, are provided. The vessels can include a ceramic outer layer and a conductive heating element, which can be provided as a conductive glaze or coating, a conductive inner layer, or a label comprising a conductive element and an RFID tag, to allow the thermal transfer or conduction of heat from the heated surface directly to the contents of the vessel, while the ceramic outer layer of the vessel insulates the contents of the vessel. Also, systems and methods for heating and controlling induction-heated vessels and for tracking loyalty, use, and/or sales using RFID-enabled induction-heated vessels are provided.

A cartridge (1) for controlled brewing of loose-leaf tea in a cup, comprising an infusion chamber (2) for containing loose tea leaves (3) and infusing a liquid with substances from the tea leaves to brew tea. A chamber wall (20) impervious to the liquid defines the infusion chamber. In the chamber wall is a passage (21) between the infusion chamber and an exterior (5) thereof. The passage has an open state in which the infusion chamber is in liquid communication with the exterior, to transport the substances from the infusion chamber into liquid in the exterior during brewing tea. In a close state the infusion chamber inside is closed off from liquid in the exterior to stop a concentration of the substances in the liquid in the exterior from increasing. A manual control manually controllable by a human-being allows to bring the passage from the open state into the closed state.

A device to provide in-line flavor for water or other liquid stored in a container. An example device includes a body having a cylindrical shape chamber formed therein, and an opening on a first end of the body. A cartridge holder fits within the chamber of the body and retains a flavoring therein for the water or other liquid. The cartridge holder has a plurality of openings for the water or other liquid to flow through. When a user drinks from the drinking end, the water or other liquid flows from the container and through the housing and mixes with a flavoring from the cartridge holder before being drawn through to the drinking end so that the user drinks a flavored water or other liquid.

A portable drinking vessel assembly removably engages an open end of a bottle neck to enable drinking directly from a bottle while aerating the liquid. The assembly comprises a vessel defined by a side wall, a bottom portion forming a bottom opening, and a top portion forming a top opening. A tapered conduit defined by a wide end and a narrow end integrally joins with the vessel through the wide end, and detachably attaches to the bottle through the narrow end. The liquid is aerated while flowing from narrow end, to wide end, and finally into the vessel. A silicone sleeve having ribs encapsulates a longitudinal portion of the conduit. The ribs engage an inner surface of the bottle neck to create a self-tapping rotatable action in the bottle neck, and a seal against the inner surface of bottle neck. The vessel joins a stand to remain upright.

A universal absorbent collar for use on vessels holding liquid. One embodiment of the collar includes a length of material, one end of which forms a loop structure through which the other end is inserted after the length of material is wrapped around the vessel. The user can tighten the collar by pulling on a single end of the strip of material. In addition, the strip of material is meant to double as a marketing tool and can feature any manner of information. A second embodiment of the device consists of a corded structure that is wrapped around a vessel and tied in place or fastened in place.

A light-up beverage container or drinking vessel has a double wall construction made up of an inner container and an outer container, the inner container having a frustoconical, straight-walled shape and the outer container having a curved sidewall when viewed from the side. In order to achieve an attractive illuminated appearance, the curved outer sidewall of the preferred drinking vessel includes facets or prism structures formed in and extending around a circumference of the curved sidewall.
