Abstract: A liquid dispenser comprises a body defining an interior containment space for containing a liquid to be dispensed and a structure configured to mount the liquid dispenser onto a drinking container such that the liquid dispenser does not obstruct drinking from a rim of the drinking container.

Abstract: A method of dispensing a liquid into a drinking container comprises the steps of: (a) providing a liquid dispenser comprising a body defining an interior containment space in which the liquid to be dispensed is contained and a structure for mounting of the body of the liquid dispenser onto the drinking container such that the liquid dispenser does not obstruct drinking from a rim of the drinking container; (b) dispensing the liquid from the liquid dispenser into the drinking container; and (c) mounting the liquid dispenser onto the drinking container via the structure of the liquid dispenser.

Abstract: A liquid dispenser includes a body defining an interior containment space having two separate, isolated chambers each for containing a human consumable liquid to be dispensed. The liquid dispenser may include a structure configured to mount the liquid dispenser onto a drinking container. The liquid dispenser further may include a first sealing element that precludes a liquid contained within a first one of the chambers from flowing through a dispensing opening; a first tear away member; a second sealing element that precludes a liquid contained within a second one of the chambers from flowing through a dispensing opening; and a second tear away member, wherein manipulation of a tear away member results in rupturing of a sealing element whereby liquid may be dispensed from a chamber. The liquid held in each chamber may be a beverage additive, a flavoring, a nutritional supplement, and/or alcohol.

Abstract: A liquid dispenser comprises a body defining an interior containment space for containing a liquid to be dispensed and a structure configured to mount the liquid dispenser onto a drinking container. The structure comprises an elongate opening formed in the body of the liquid dispenser that generally divides the liquid dispenser into two portions. Approximately half of the volume of the interior containment space is located in the first portion of the body of the liquid dispenser. Alternatively, substantially all of the volume of the interior containment space is located in the first portion.

Abstract: A combination of a drinking container and a liquid dispenser comprises a drinking container defining an interior containment space for a beverage for human consumption and a liquid dispenser, which comprises a body defining an interior containment space and a structure by which the body of the liquid dispenser is mounted onto the drinking container such that the liquid dispenser does not obstruct drinking from a rim of the drinking container.
