Definitions

• TITLE Tamper evident closure.
• the present invention relates to a tamper evident closure, i.e. a closure comprising devices that can provide evidence of first opening.
• WO 03/095326 discloses a safety closure for bottles, provided with a tamper optical indicator.
• the closure comprises a disk member which is transversal with respect to a cap.
• the disk member exhibits on its upper surface at least one projection and coupling means on its lower surface.
• Breakable container means containing substances capable of changing the conditions of the visible zone through a transparent portion of the cap are provided between the projection of the upper surface of the disk member.
• the coupling means determines a relative movement between the disk member and the breakable container means when a user unscrews the cap for the first opening so as to cause the penetration between the projection and the container means thereby causing the discharge of the fluid contained in the container means and a chromatic change of the transparent portion.
• This closure has the drawback that construction becomes complicated due to use of chemical substances, such as suitable liquids having chromatic properties, and containers therefor which need to be arranged in the cap.
• WO 2009/128095 discloses a threaded cap comprising a threaded undercap and an overcap coaxial and integral therewith and external thereto so as to define a pocket which houses, movable in the longitudinal direction, a element comprising an upper portion and a lower portion substantially aligned in the longitudinal direction and joined together by a weakened line, before first opening.
• the weakened line breaks so that the lower portion falls away from the closure and the upper portion falls down in abutment against a stop surface. This causes the lower portion to be visible or may expose a portion of the undercap.
• This closure has the drawback that the lower portion may get stuck upon first opening so that it does not fall.
• WO 2005/049443 and GB 2 450 939 disclose a tamper-evident closure having a first portion with inner and outer parts and a second portion.
• the outer part is movable relative to the inner part from a first position, corresponding to the position before first opening, in which the outer par is immediately adjacent to the second portion, and a second position, corresponding to the position after first opening, in which there is an unobstructed gap therebetween.
• the inner and outer parts are adapted to become irreversibly locked in the second position so that the outer part cannot be moved back to the first position to close the gap. In order to open the closure the outer part is grasped and turned.
• the tightness of fit between the inner part and the neck portion of the container is designed to be greater than that between the inner part and the outer part. Therefore, when the outer part is initially turned it is the outer part which moves axially upwards relative to the inner part while the inner part remains stationary. This closure has the drawback that, if the inner part moves before the outer part has reached the second position, the outer part cannot be become locked with the inner part so that the tamper-evident mechanism may fail.
• the object of the present invention is to at least partially fulfill the above need, while at least partially obviating prior art drawbacks.
• the present invention provides a closure assembly having advantages in terms of simple fabrication, greater strength, more compact design and/or higher versatility.
