The assembly according to claim 1 wherein the action is a squeezing action. 3. The assembly according to claim 1 wherein the handle surface provides a trigger cooperating with the grip surface. 4. The assembly according to claim 1 whereby the fixed part of the applicator further comprises an additional grip surface part for contact with at least one finger. 5. The assembly according to claim 1 whereby the grip surface for contact with the palm of the hand has a surface area of at least 10 cm2. 6. The assembly according to claim 1 whereby the handle surface has a surface area of at least 4 cm2. 7. The assembly according to claim 1 whereby the resilient part is connected to the moveable part above the pivot joint and is connected to the fixed part at and below the pivot joint, whereby a reversible deformation of the resilient part allows the pivoting of the moveable part with respect to the fixed part. 8. The assembly according to claim 1 wherein the container comprises a head which is flanged to the container by a head flange, wherein the container valve is flanged to the container head by a valve flange, wherein the fixed part of the applicator is provided with a first cylindrical portion comprising a protruding rim for an operation selected from snapping the applicator onto the head flange of the container and sliding the applicator over the valve flange of the container, and combinations thereof, thereby attaching the applicator to the container. 9. The assembly according to claim 8 wherein the fixed part of the applicator is provided with a second cylindrical portion comprising a protruding rim for an operation selected from snapping the applicator onto the head flange of the container, sliding the applicator over the head flange of the container, and combinations thereof, thereby attaching the applicator to the container. 10. The assembly according to claim 1 wherein the container comprises a head which is flanged to the container by a head flange and wherein the fixed part of the applicator is provided with a second cylindrical portion comprising a protruding rim for an operation selected from snapping the applicator onto the head flange of the container, sliding the applicator over the head flange of the container, and combinations thereof, thereby attaching the applicator to the container. 11. The assembly according to claim 1 wherein the applicator is further comprising a safety seal for securing the relative position of the moveable part to the fixed part, and a hinge which is attached to the safety seal and allows for relative rotational movement of the safety seal between a closed position and an open position such that the safety seal is provided for reversible movement. 12. The assembly according to claim 11 wherein the moveable part of the applicator is provided with a first means and the safety seal is provided with a second means for engaging with the first means and by this engagement securing the moveable part from moving relative to the fixed part. 13. The assembly according to claim 11 wherein the safety seal is further provided with a first means for engagement with a second means provided as part of the fixed part for cooperation with the first means and by their engagement further securing the position of the safety seal relative to the fixed part. 14. The assembly according to claim 1 wherein the applicator is further comprising a cavity for providing an accessory object. 15. The assembly according to claim 14 wherein a safety seal is present and the safety seal is provided as the cover for closing off the cavity for the accessory object. 16. The assembly according to claim 1 wherein the applicator is further provided with a closure element suitable for closing the open end of an element selected from a trunk and a hose. 17. The assembly according to claim 1 further comprising an element selected from a trunk and a hose which is provided together with the applicator, and is accommodated for enabling the container content to be discharged in a well-aimed manner. 18. The assembly according to claim 1 wherein the applicator is further provided with an external flat surface. 19.
