Pasty food product dispensing and dosing device

Abstract

A pasty food dispensing and dosing device for pasty food products packed in sachets. The device does not require a power source and can be used in a hygienic way, since the product does not contact any part of the device. Thus, beneficial, practical, safe and functional results are attained. The device comprises a base, a cap connected to a lock, and a trigger lever that activates a system that secures and controls the opening of a dispensing nozzle of the sachet so that the nozzle opens and the product is dispensed. When returned to an initial position, the system stretches the dispensing nozzle to prevent the product from exiting. The dosage of the product is regulated by a dosing system that triggers two spindles with helical grooves located inside the base to rotate through orifices of a piston, which displaces the piston and compresses the sachet.
