Tray for positioning elongated objects, in particular syringe bodies or syringes

Abstract

This tray includes spaced apart openings arranged in parallel rows, intended to receive the bodies of the elongated objects, and projections making it possible to place the flanges of the elongated objects inserted in these openings in a determined angular position on the tray when the bodies of these elongated objects are engaged in these openings. According to the invention: said projections are arranged so as to place the length of said flanges in a determined angular position with respect to the rows of openings, and the openings of a first row of openings are arranged with respect to a second row of openings adjacent to said first row, such that after installation of the elongated objects on the tray, the flanges of the objects inserted in the openings of said the first row imbricates with the flanges of the objects inserted in the openings of said second row, i.e. each flange of an object of said the first row is positioned in a space existing between the two adjacent flanges of the objects of said second row, in the immediate vicinity of these two flanges.

1 . A tray for positioning elongated objects, each having a cylindrical body and a noncircular flange having a length greater than its width, the tray comprising a plate with spaced apart openings arranged in parallel rows, intended to receive the bodies of the elongated objects, and the tray having projections that place the flanges of the elongated objects inserted in these openings in a determined position on the tray when said bodies of these elongated objects are engaged in the openings;
 wherein said projections are arranged so as to place the length of said flanges in a determined angular position with respect to at least one of the rows of openings, and   the openings of a first row of openings are arranged with respect to a second row of openings adjacent to said first row, such that after installation of the elongated objects on the tray, the flanges of the objects inserted in the openings of said the first row imbricates with the flanges of the objects inserted in the openings of said second row.   
     
     
         2 . A tray according to  claim 1 , wherein each projection includes a cylindrical stem and a radial wall, extending radially from this cylindrical stem, said cylindrical stem being arranged substantially between two openings of the same row of openings so that the flanges of the elongated objects engaged in these openings come in its immediate vicinity, as well as the flange of an elongated object engaged in the contiguous opening of the adjacent row, and said radial wall being arranged according to the desired determined angular position of the flanges of the elongated objects and being intended to be inserted between the flanges of the elongated objects inserted in two contiguous openings of two rows of adjacent openings. 
     
     
         3 . A tray according to  claim 1 , wherein said projections are in the form of rectilinear walls or of studs having a form corresponding to spaces remaining between the flanges of two adjacent rows of objects. 
     
     
         4 . A tray according to  claim 1 , wherein said projections are arranged so that the flanges come in contact therewith or come in the immediate vicinity therewith when the elongated objects are in a complete engagement in the openings of the tray, these projections thus allowing to maintain the flanges in said determined angular position. 
     
     
         5 . A tray according to  claim 1 , wherein said projections include sloped edges forming ramps which the flanges are intended to meet during the engagement of the objects in the openings of the tray and against which these flanges slip further to this meeting, this slip allowing to bring the flanges in said determined angular position. 
     
     
         6 . A tray according to  claim 5 , wherein said projections are arranged on two diametrically opposed sides of the openings, and said two projections of a same opening include edges of reversed slopes from one projection to the other of this same opening. 
     
     
         7 . A tray according to  claim 5 , wherein said sloped edges ( 10   d ) of said projections ( 10 ) are rectilinear. 
     
     
         8 . A tray according to  claim 5 , wherein said sloped edges of the projections exhibit a curved form. 
     
     
         9 . A tray according to  claim 1 , wherein the projections exhibit bevelled free edges, which the flanges are intended to meet during the engagement of the objects in the openings of the tray and against which these flanges slip further to this meeting. 
     
     
         10 . A tray according to  claim 1 , wherein said projections are interrupted from a row of openings to an adjacent row of openings. 
     
     
         11 . A tray according to  claim 1 , wherein said projections are continuous from a row of openings to an adjacent row of openings. 
     
     
         12 . A tray according to  claim 1 , further comprising chimneys delimiting said openings for the engagement of the objects, and in that said projections are arranged on the level of the free ends of these chimneys. 
     
     
         13 . Tray according to  claim 1 , wherein said projections include retention means making it possible to carry out retention of the flanges, in particular by clamping or snapping. 
     
     
         14 . A tray according to  claim 1 , further comprising chimneys delimiting said openings for receiving said elongated objects, said chimneys having lengths such that the flanges of the elongated objects received therein are, after installation of the tray in a packaging box and installation on the box of a membrane immobilized with respect to the box, in the immediate vicinity of this membrane. 
     
     
         15 . A tray according to  claim 1 , further comprising a heightening base part making it possible to heighten the plate of the tray with respect to a shoulder for supporting the tray arranged in a packaging box, the base part making it possible to raise the tray so that the flanges of the elongated objects placed on the tray are located in the immediate vicinity of a membrane immobilized with respect to the box.
