A dispenser containing a substance to be applied on a patient is described. The dispenser includes a plunger, a tube and a perforated element located inside the tube. The tube contains openings at its application end. When the plunger is pushed during application, the substance is squeezed through the perforated element and the openings and is applied to the patient. Selection of the height of the perforated element and presence or absence of alignment between the perforations of the perforated element and the openings allows control of the application of the substance on the patient.

1. A dispenser adapted to contain a substance to be applied on a human or animal patient, comprising: a plunger;a tube, the plunger being adapted to slide inside the tube for application of the substance, the tube containing a plurality of openings at a first end region thereof, the first end region
1. A dispenser adapted to contain a substance to be applied on a human or animal patient, comprising: a plunger;a tube, the plunger being adapted to slide inside the tube for application of the substance, the tube containing a plurality of openings at a first end region thereof, the first end region of the tube having a planar face, the plurality of openings being located on the planar face of the first end region, the planar face of the first end region being adapted to spread the substance on a skin region of the human or animal patient during application of the substance to the skin region;a perforated element located inside the tube, the perforated element having a height that provides a distance between perforations of the perforated element and the first end region, wherein location of the perforated element inside the tube is such that the substance to be applied is adapted to be disposed inside the tube above the perforated element before application, and wherein, during use of the dispenser, the plunger slides inside the tube to push the substance through the perforated element and through the plurality of openings at the first end region of the tube, thus expelling the substance from the dispenser for application on the human or animal patient, the height further defining a maximum length of run of the plunger inside the tube during use of the dispenser; wherein correspondence or lack of correspondence between perforations of the perforated element and the plurality of openings on the planar face is selectable to obtain a desired path length and a consequent desired application delay of the substance on the skin of the human or animal patient. 2. The dispenser of claim 1, wherein geometry of the perforated element is selectable to obtain a desired path length and a consequent desired application delay of the substance on the human or animal patient. 3. The dispenser of claim 2, wherein said geometry of the perforated element is selected from the height of the perforated element and/or shape, size and/or amount of perforations. 4. The dispenser of claim 1, further comprising a cap to cover the end region of the tube. 5. A method of using the dispenser of claim 4, comprising: sliding the dispenser over a substance-covered body part of the patient to spread the substance. 6. The dispenser of claim 1, wherein the tube comprises side wings at a second end region thereof opposite the first end region. 7. The dispenser of claim 6, wherein the perforated element comprises a plurality of holes and/or slits. 8. The dispenser of claim 1, further comprising the substance, prefilled in the tube. 9. The dispenser of claim 8, wherein the substance is prefilled after fabrication of the dispenser. 10. The dispenser of claim 1, said dispenser being a disposable dispenser. 11. The dispenser of claim 1, wherein the perforated element is located at a bottom of the tube, in proximity of said first end region. 12. A method of using the dispenser of claim 1, comprising: locating the end region of the tube in proximity of or on a body region of the human or animal patient;pushing the plunger inside the tube, whereby the substance passes through the perforated element and through the plurality of openings and is expelled from the tube and applied to the skin region of the human or animal patient. 13. The method of claim 12, further comprising moving the dispenser along the skin region while pushing the plunger inside the tube. 14. The dispenser of claim 1, wherein a perimeter of the planar face is round.
