Abstract
The invention relates to a device for extracting a food substance contained in a closed refill. The device includes a hollow body with a housing for accommodating the refill, a water inlet channel passing through the body and communicating with the housing, and a plurality of piercing elements arranged in the housing for piercing the refill in several different places in order to allow the water to pass through the refill. The piercing elements are spaced apart in the housing with respect to the water inlet direction in the housing. Each piercing element includes: (i) a base portion secured to the body and projecting into the housing, designed to engage at least partially inside the refill, and (ii) a cutting surface which intersects the base portion at an acute angle.
