Abstract
An applicator has at least one barrel and a piston moveable within the at least one barrel between a variable first position and a second position. Movement of the piston towards the first position can draw a first fluid into the barrel, and movement of the piston towards the second position can force the first fluid out of the barrel. A fluid inlet valve allows the fluid to flow into the barrel at least under action of the piston, and a fluid outlet valve allows the fluid to flow out of the barrel. The piston is biased toward the first position and a dosage control part. An actuator is operable to move the piston to dispense the first fluid from the applicator.
Claims20
An applicator comprising:
- at least one barrel;
- a piston moveable within the at least one barrel between a variable first position and a second position, wherein, in use, movement of the piston towards the first position can draw a first fluid into the barrel, and movement of the piston towards the second position can force the first fluid out of the barrel;
- at least one fluid inlet valve to allow the fluid to flow into the at least one barrel at least under action of the piston, and at least one fluid outlet valve to allow the first fluid to flow out of the at least one barrel at least under action of the piston;
- biasing means to bias the piston toward the first position;
- a dosage control part that slides linearly on a longitudinal axis of the at least one barrel, and can lock in any one of a plurality of notches that each correspond to a dosage mark to abut an abutment portion which in turn defines the variable first position of the piston and therefore a dosage of the first fluid;
- and
- piston actuating means operable to move the piston towards the second position to dispense the first fluid from the applicator.
- wherein a user may set the dosage of the applicator via the dosage control part and deliver a dosage of the first fluid by the piston actuating means.
A method of using an applicator, comprising or including the steps of:
- fluidly connecting supply of a first fluid to a manifold of the applicator;
- adjusting a dosage of a first piston within a first barrel of the applicator using a first dosage control part, where the first dosage control part is slidingly lockable along a major axis of the first barrel in any one of a plurality of notches that each correspond to a dosage mark, the first dosage control part abutting a first abutment portion on the first piston which in turn varies a first position of the first piston and therefore the dosage of the first fluid;
- priming the first barrel using a first lever portion;
- forcing a first fluid from the first barrel by moving the first piston from the first position to a second position within the barrel, by use of a piston actuating means which, the first fluid moving from the first barrel via at least one fluid outlet valve;
- and
- drawing the first fluid from the supply into the first barrel by the first piston moving from the second position back to the first position, the first fluid moving in via a first fluid inlet valve, the movement from the first position to the second position being biased;
- wherein a user may set the dosage of the applicator via the first dosage control part and deliver a dosage of the first fluid by the piston actuating means.
