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 drinking device for the retronasal perception of an aroma substance comprises a storage container (12) for drinking liquid, at least one aroma container (20), through which air can flow, and a transporting channel (18) for drinking liquid, the transporting channel running from the storage container (12) to a mouth end (28) of the drinking device (10), and also comprises an air channel (22) for transporting aromatized air, said air channel running from at least one of the at least one aroma containers (20) to the transporting channel (18) for drinking liquid or to the mouth end (28).

A drinking straw comprising an elongate tubular body of an insoluble material having an internal coating comprising a matrix containing an active agent dispersed within the matrix, the body sized to allow a carrier liquid to be drawn therethrough such that passage of the carrier liquid causes the matrix to release the active agent into the carrier liquid to be consumed by a drinker. The matrix comprises partially hydrolysed guar gum, an acid and a modified cellulose. The active agent includes sweetener, flavour, a nutrient and/or a pharmaceutical and optionally colour. The coating is prepared by mixing the matrix with water to form a paste or syrup and is then used to coat the inside surface of a drinking straw to a thickness of less than 1 mm. Liquid drawn through the straw dissolves or breaks down the coating, releasing the active agent into the liquid for consumption.

A drinking device for the retronasal perception of an aroma substance comprises a storage container for drinking liquid, at least one aroma container, through which air can flow, and a transporting channel for drinking liquid. The transporting channel runs from the storage container to a mouth end of the drinking device. The drinking device also comprises an air channel for transporting aromatized air. The air channel running runs from at least one of the at least one aroma containers to the transporting channel for drinking liquid or to the mouth end.

Provided are improved drinking straws comprising an integrated device providing an anti-outflow capability, methods for their use, and processes for their manufacture. Specifically, the drinking straw is formed substantially of a cellulosic material and wherein the drinking straw and the device providing the anti-outflow capability comprising a flexible flap having a fixed end affixed to an interior surface of a sidewall of the drinking straw, and a part of the flexible flap obscuring an inlet orifice passing through the sidewall adjacent to the flexible flap and forming a liquid tight seal when a reduced pressure condition exists within the interior flow passage of the drinking straw.

A drinking straw includes a generally elongate tube having a sidewall defining an internal bore, wherein one end of the straw is provided with a piercing projection formed from a portion of the sidewall and reinforced by a folded portion of the sidewall. The straw is manufactured from an elongate tube on which a piercing projection is formed at one end by folding a portion of the sidewall at that end to reinforce the projection.

The present invention relates to a single use tubular straw for conditioning of a liquid passing through including; a cylindrical body for passing of the liquid; a bottom opening for inflow of the liquid in the cylindrical body; a top opening for outflow of the liquid from the cylindrical body; at least one conditioning agent for the conditioning of the liquid passing through the cylindrical body; and a seal for closing the top opening and the bottom opening of the cylindrical body. The conditioning agent is disposed on the inner surface of the cylindrical body and get dissolved in the liquid on passing of the liquid through the cylindrical body providing the conditioned liquid at the top opening of the cylindrical body.

A disposable packaging form is provided for brewed, hot drinks. The invention allows a user to brew the hot drink, squeeze out the brewed contents, and stir the contents of the hot drink. Each action can be performed multiple times before disposal. In some embodiments, the device of the present invention dispenses sweeteners, creamers, flavorings and condiments. The present invention frees the user of the inconvenience of having to collect, wash, or dispose of the stirrers, squeezers and bags of the hot drink individually.

A drinking straw comprising an elongate tubular body of an insoluble material having an internal coating comprising a matrix containing an active agent dispersed within the matrix, the body sized to allow a carrier liquid to be drawn therethrough such that passage of the carrier liquid causes the matrix to release the active agent into the carrier liquid to be consumed by a drinker. The matrix comprises partially hydrolysed guar gum, possibly in combination with an acid and/or modified cellulose. The active agent includes sweetener, flavour, a nutrient and/or a pharmaceutical and optionally colour. The coating is prepared by mixing the matrix with water to form a paste or syrup and is then used to coat the inside surface of a drinking straw to a thickness of less than 1 mm. Liquid drawn through the straw dissolves or breaks down the coating, releasing the active agent into the liquid for consumption.

A drinking straw having a coating on its interior surface is disclosed. The drinking straw has a coating on its interior surface. The coating comprises an active ingredient, a film forming agent, a non-ionic surfactant, and optionally a diluent. The active ingredient may be a cannabinoid. A method of manufacturing a straw having a coating on its interior surface is also disclosed. The method comprises combining the active ingredient with a carrier, and blending to form a mixture; adding a non-ionic surfactant and a plasticizer to the mixture; agitating the mixture to form a homogeneous first dispersion; adding a film forming agent to the first dispersion and mixing until homogeneous; applying the dispersion to the interior surface of the straw; agitating the straw to cover at least part of the interior surface with the first dispersion; and drying the first dispersion inside the straw to form the coating.
