Tamper evident device

Abstract

The invention relates to a security device ( 10 ) for a container such as a bag or envelope closeable by a slide fastener having a slider ( 16 ). The security device ( 10 ) includes a lower part ( 12 ) for attachment to the container and means ( 14 ) for attaching the security device ( 10 ) to the slider ( 16 ), directly or indirectly. An upper part ( 20 ) retains the attaching means ( 14 ). Receiving means ( 24 ) can receive a frangible seal ( 26 ) and prevent retraction of the frangible seal ( 26 ), except by fracture thereof. Means ( 28 ) limits access to the attaching means ( 14 ) and the receiving means ( 24 ). The security device ( 10 ) includes an area of weakness ( 30 ) adapted to fracture if the security device ( 10 ) is prised from the container.

1 . A security device for a container closeable by a slide fastener having a slider, the security device including:

     wherein the security device includes an area of weakness adapted to fracture if the security device is prised from the container. 
   
   
       2 . The security device of  claim 1 , wherein the security device is adapted for attachment to the container by fastening means in such a way that the security device is moveable, relative to the fastening means after assembly while still being secured to the container. 
   
   
       3 . The security device of  claim 1 , wherein the attaching means is attached to a zip pull for the slider. 
   
   
       4 . The security device of  claim 1 , wherein the lower part is a rivet plate. 
   
   
       5 . The security device of  claim 4 , wherein the upper part forms a chamber base in which is located the receiving means. 
   
   
       6 . The security device of  claim 5 , wherein the means to limit access to the attaching means and the receiving means forms a cover for the chamber. 
   
   
       7 . The security device of  claim 1 , wherein the upper part includes a pair of spaced rivet holes. 
   
   
       8 . The security device of  claim 7 , wherein the area of weakness is located between the spaced rivet holes. 
   
   
       9 . The security device of  claim 1 , wherein the area of weakness is visible when the frangible seal is received in the receiving means. 
   
   
       10 . The security device of  claim 1 , wherein the area of weakness is located around a rivet hole in the upper part. 
   
   
       11 . The security device of  claim 2 , wherein the means to limit access to the attaching means and the receiving means is adapted to be spaced apart from the fastening means. 
   
   
       12 . The security device of  claim 1 , wherein the receiving means includes a barrier adapted to exclude entry of a frangible seal without separate legs. 
   
   
       13 . The security device of  claim 12 , wherein the barrier is a pin dividing the receiving means. 
   
   
       14 . A security device for a container closeable by a slide fastener having a slider, the security device including:
 a lower part adapted for attachment to the container;   means for attaching the security device to the slider, directly or indirectly;   an upper part for retaining the attaching means; and   means to limit access to the attaching means;   
     wherein the security device is adapted for attachment to the container by fastening means in such a way that the security device is moveable, relative to the fastening means after assembly while still being secured to the container. 
   
   
       15 . The security device of  claim 14 , wherein the attaching means is attached to a zip pull for the slider. 
   
   
       16 . The security device of  claim 14 , wherein the lower part is a rivet plate. 
   
   
       17 . The security device of  claim 14 , wherein the upper part includes a pair of spaced rivet holes. 
   
   
       18 . The security device of  claim 14 , wherein the lower part has anchor points for the fastening means. 
   
   
       19 . The security device of  claim 18 , wherein the anchor points are shaped to allow movement between the fastening means and the lower part in use. 
   
   
       20 . The security device of  claim 18 , wherein the fastening means are adapted to be spaced from the access limiting means in use.
