A product dispensing system includes a partially-open container for retaining a supply of the product, a mechanism for dispensing a quantity of the product from the container, and a remotely-activated security device for selectively restricting the dispensing of product from the container. In one embodiment, the security device is in the form of a spherical enclosure that is mounted over the inlet port for a draw tube of the dispensing mechanism. In use, the security device includes an activation mixture, such as an expandable adhesive, that transitions the security device between a first state and a second state in response to an application of certain non-mechanical stimuli, such electromagnetic energy of a particular profile, the security device restricting the passage of the product through the draw tube when disposed in the first state and permitting the passage of the product through the draw tube when disposed in the second state.
