Device for tamper protecting and authenticating a liquid product distributor
A device for tamper protecting and authenticating a liquid product distributor including a container with a cylindrical neck with a seal engaged therein, further including an indicator element with a collar which is elastically inwardly collapsible and whose largest diameter is greater that the neck internal diameter and which is removably disposed on the lower part of the seal and is trapped in the container after a forced penetration through the neck. The indicator element includes a sleeve in which the lower part of the seal is radially clamped.
1. A device for tamper-proofing and authenticating a liquid dispenser comprising a reservoir provided with a cylindrical neck into which closure means are engaged, said device being characterized in that it is constituted by a control element provided with a collar that is elastically foldable inwards and whose largest diameter is greater than the inside diameter of the neck and that is disposed removably at the bottom of said closure means while being trapped in said reservoir after it has been inserted by force through said neck, further characterized in that said control element comprises a bushing inside which the bottom portion of the closure means is radially clamped, said closure means extending through said bushing, and said bushing being provided with a peripheral skirt forming a stiffener and disposed under the collar preventing said collar from flexing downward.
2. A device according to claim 1 , characterized in that the inside wall of said bushing carries an axial keying rib co-operating with a groove carried by the closure means.
3. A device according to claim 1 , characterized in that said closure means are constituted by a pump body.
4. A device according to claim 1 , characterized in that said collar is frustoconical and flares away from the axis of the neck and upwards.
5. A device according to claim 1 , characterized in that said control element includes a traceability system.
6. A device according to claim 1 , characterized in that said collar is constituted by a series of radial fins.
7. A device according to claim 1 , characterized in that said control element fits the outside profile of said closure means.
8. A device for tamper-proofing and authenticating a liquid dispenser comprising a reservoir provided with a cylindrical neck into which closure means are engaged, said device being characterized in that it is constituted by a control element provided with a collar that is elastically foldable inwards and whose largest diameter is greater than the inside diameter of the neck and that is disposed removably at the bottom of said closure means while being trapped in said reservoir after it has been inserted by force through said neck, further characterized in that said control element comprises a bushing inside which the bottom portion of the closure means is radially clamped, said bushing being provided with a peripheral skirt forming a stiffener and disposed under the collar preventing said collar from flexing downward, wherein said closure means are constituted by a pump body and said control element is formed integrally with the pump body.
