SPILL-RESISTANT CUPS WITH ACTIVE INGREDIENT DELIVERY SYSTEMS

摘要

Spill-resistant cups for consuming beverages with delivery systems for simultaneously dispensing one or more agents which can reduce the rate of beverage-induced tooth decay and/or enamel erosion are disclosed herein. In one embodiment, the spill-resistant cup can include a hollow cup body defining a beverage holding chamber. The spill-resistant cup also includes a lid assembly with a drinking spout having one or more spaced-apart drinking holes. The drinking spout is configured to be engaged by a consumer's mouth. The lid assembly can positively engage the cup body to enclose the beverage holding chamber. The spill-resistant cup can also include an agent delivery system for controlled delivery of the active ingredient to the consumer's mouth. Further, the spill-resistant cup can include a flow control element configured to limit a flow rate of the beverage from the beverage holding chamber to the drinking holes disposed in the drinking spout.
