Packaging tray for caps intended to seal bottles for pharmaceutical use

Abstract

A packaging tray for caps includes a generally plate-shaped base having an upper face and a lower face extending along a main plane (x,y); a plurality of abutments, each abutment being configured to be in contact with a cap when a plurality of caps is held on the side of the lower face of the base; and a plurality of fastening systems, each fastening system being associated with an abutment and being configured to hold a cap against the abutment. Each of the abutments is connected to the base by flexible bridges enabling the abutment to move perpendicularly to the main plane (x,y).

What is claimed is: 
     
         1 . A packaging tray for caps, comprising:
 a generally plate-shaped base having an upper face and a lower face, the upper face and the lower face extending along a main plane (x,y);   a plurality of abutments, each abutment of the plurality of abutments being configured to be in contact with a respective cap when a plurality of caps is held on a side of the lower face of the base, each abutment of the plurality of abutments being connected to the base by flexible bridges enabling the abutment to move perpendicularly to the main plane (x,y); and   a plurality of fastening systems, each fastening system of the plurality of fastening systems being associated with an abutment and being configured to hold a cap against the abutment.   
     
     
         2 . The packaging tray of  claim 1 , wherein two or three of the flexible bridges connect each abutment to the base. 
     
     
         3 . The packaging tray of  claim 2 , wherein each flexible bridge is U-shaped in a plane normal to the main plane (x,y). 
     
     
         4 . The packaging tray of  claim 2 , wherein each flexible bridge is S-shaped in a plane normal to the main plane (x,y). 
     
     
         5 . The packaging tray of  claim 1 , wherein each fastening system of the plurality of fastening systems comprises flexible tabs, each of the flexible tabs having a first free end capable of moving in a direction along the main plane (x,y). 
     
     
         6 . The packaging tray of  claim 5 , wherein each fastening system of the plurality of fastening systems comprises three flexible tabs. 
     
     
         7 . The packaging tray of  claim 5 , wherein each of the flexible tabs has a protrusion configured to grip an upper portion of a cap so as to hold the cap against the abutment. 
     
     
         8 . The packaging tray of  claim 5 , wherein each of the flexible tabs has a second end secured to the base. 
     
     
         9 . The packaging tray of  claim 5 , wherein each of the flexible tabs has a second end connected to a proximal end of a flexible bridge, a distal end of the flexible bridge being secured to the base. 
     
     
         10 . The packaging tray of  claim 1 , wherein each abutment of the plurality of abutments has a projection extending from a side of the upper face of the base. 
     
     
         11 . The packaging tray of  claim 10 , wherein the projection has a tubular shape. 
     
     
         12 . The packaging tray of  claim 1 , wherein at least one abutment of the plurality of abutments comprises a damping element configured to be positioned against a cap. 
     
     
         13 . The packaging tray of  claim 12 , wherein the damping element is removable. 
     
     
         14 . The packaging tray of  claim 1 , wherein the base is perforated and comprises stiffening ribs arranged on the upper face and/or on the lower face thereof. 
     
     
         15 . The packaging tray of  claim 1 , further comprising spacers connected to the base and extending along an axis (z) normal to the main plane (x,y) on a side of the lower face. 
     
     
         16 . The packaging tray of  claim 1 , wherein each of the flexible bridges is U-shaped in a plane normal to the main plane (x,y). 
     
     
         17 . The packaging tray of  claim 1 , wherein each flexible bridge is S-shaped in a plane normal to the main plane (x,y).
