A method and package for controlled metered dispensing of a fluid product contained in the package having a metered dispensing system, each time the package is opened or uncapped are disclosed. By the present method and package, the maximum amount of product that can be dispensed is limited to a single metered dose after each uncapping of the package. Specifically, the metered dispensing system is configured to allow dispensing of only a single metered dose of a liquid, viscous liquid, gel, paste, or semi-solid product contained in the package and to prevent further dispensing of additional doses of product until at least one specific and deliberate step is taken that re-activates or re-engages the dispensing system. Such deliberate step is preferably one that occurs through natural use of the package, such as re-capping the open package after one single dose has been dispensed. Only after the open package has been re-capped can the next dose of product be available for dispensing. Thus, the system provides child resistance by preventing a child or other person who does not have the mental capacity to comprehend the threat of serious injury from contact with or improper use of the product, from gaining access to more than a single dose of the product each time the package is uncapped.

1. A method for controlled dispensing of a fluid product contained in a non-collapsible package having a child resistant closure, a metered dispensing system having a dose chamber with a venting means, and a flow control member for regulating the flow of fluid product between said package and said dose chamber and including a one-way check valve that prevents the metered amount of product that has entered the dose chamber from returning back to said package, wherein only a single metered dose can be dispensed each time the package is uncapped, said method comprising the step of recapping the uncapped package and engaging said child resistant closure in order to activate said dispensing system to deliver a next dose, thereby preventing inadvertent overdosing. 2. A package having a dispensing system for controlled metered dose dispensing of a fluid product, comprising (a) a container having a body for holding a fluid product and a discharge opening for dispensing said fluid product, said container body being non-collapsible; (b) a closure fitted for capping said container and sealing said discharge opening; (c) a dose chamber in communication with said discharge opening, said dose chamber being capable of metering a predetermined amount of fluid product that can be dispensed from the container after each removal of said closure and having an inlet through which fluid product in said container body can flow into said dose chamber and a venting means; (d) a flow control member for regulating the flow of fluid product between said container body and said dose chamber and including a one-way check valve that prevents the metered amount of product that has entered the dose chamber from returning back to the container body; and (e) an actuator for triggering product flow from the container body into the dose chamber to provide a metered dose ready for dispensing, said actuator being associated with or cooperating with said closure, wherein the package is configured such that only a single metered dose can be dispensed each time the package is uncapped and the uncapped package must be recapped in order to activate the dispensing system to deliver additional product. 3. A package having a dispensing system for controlled metered dose dispensing of a fluid product according to claim 2, wherein said flow control member is selected from a one-way flapper valve, a one-way plunger valve, a ball valve or a sliding valve. 4. A package having a dispensing system for controlled metered dose dispensing of a fluid product according to claim 2, wherein said closure is configured with a variable dose feature for selecting a desired dose amount from a series of predetermined dose amounts. 5. A package according to claim 2 having a dispensing system for controlled metered dose dispensing of a fluid product in liquid, paste, gel or semi-solid form. 6. A package according to claim 5 for controlled metered dose dispensing of a fluid product selected from oral medicines, topical ointments and creams, eye drops, dentifrices, mouthwashes, cosmetics, detergents, cleansers, drink mixes, oils, condiments, extracts, flavorings and sauces.
