1. ) A closure for a liquid container comprising at least one temporary interlocking mechanism not visible during the closed state of the container:

  • a) wherein the temporary interlocking mechanism, has a two part fastener that engages a moveable part of the closure with a fixed part of the closure, and(b) wherein the temporary interlocking mechanism includes at least one element that breaks or irreversibly deforms during the initial opening of the container wherein the breaking or the deformation requiring a force with a magnitude higher than a threshold force, and(c) further wherein the temporary interlocking mechanism is positioned in a location different from the location of an orifice of the closure or from a path that a liquid content of the container follows during dispensing,(d) and further wherein the temporary interlocking mechanism, after breaking or irreversibly deforming during the initial opening of the container, does not interfere with the opening and closing of the container during its subsequent use, and(e) wherein the ratio of the threshold force value to the required force to open the closure after the initial opening is larger than 1.25.
