Tray for brittle columnar body

Abstract

There is disclosed means for satisfactorily storing or transporting a columnar product formed of a brittle material which is easily damaged. The means is a plate-like tray 1 including two pockets. In this tray 1 , a bottom surface forming the pockets 4 has bottom surface raised portions, and side surfaces forming the pockets 4 have side surface raised portions. When a brittle columnar body is held or transported using this tray 1 , damage can be prevented.

1 . A tray for a brittle columnar body which is used to transport or holding the brittle columnar body,
 the tray having a plate-like shape and at least one pocket for holding the brittle columnar body at the end side of the columnar body; and   having raised-portions respectively on a bottom surface and side surfaces of the tray defining a part of said pocket at portions except a corner portion of the pocket where the bottom surface and the side surface of the tray come in contact,   wherein a height of the raised portion disposed on the bottom surface of the tray: TB, a distance between the side surface facing to the corner of the tray of the raised portion disposed on the side surface of the tray and the bottom surface of the tray: DS, a height of the raised portion disposed on the side surface of the tray: TS, and a distance between the side surface facing to the corner of the tray of the raised portion disposed on the bottom surface of the tray and the side surface of the tray: DB,   meet relations of DS>TB and DB>TS.   
   
   
       2 . The tray for the brittle columnar body according to  claim 1 , wherein the raised portion is disposed on the side surface as a part for defining a pocket and said raised portion is constituted of a member which is different from that of the side surface. 
   
   
       3 . The tray for the brittle columnar body according to  claim 2 , wherein on one tray member which does not have the only raised portion disposed at the side surface forming the pocket, there is superimposed another tray member having the only raised portion disposed at the side surface forming the pocket. 
   
   
       4 . The tray for the brittle columnar body according to  claim 1 , which is formed of a main material including one of polypropylene, polyethylene, polyethylene terephthalate, vinyl chloride, iron, aluminum and paper. 
   
   
       5 . The tray for the brittle columnar body according to  claim 4 , which is formed of a foam material. 
   
   
       6 . A packaging body comprising:
 A set of two trays for the brittle columnar body;   each tray having a plate-like shape and at least one pocket for holding the brittle columnar body at side of said columnar body; and   having a raised portions respectively on bottom surfaces and side surfaces of the tray defining a part of a pocket except a corner portion of the pocket where the bottom surface and the side surface of the tray come in contact,   wherein a height of the raised portion disposed on the bottom surface of the tray: TB, a distance between the side surface facing to the corner of the tray of the raised portion disposed on the side surface of the tray and the bottom surface of the tray: DS, a height of the raised portion disposed on the side surface of the tray: TS, and a distance between the side surface facing to the corner of the tray of the raised portion disposed on the bottom surface of the tray and the side surface of the tray: DB,   meet relations of DS>TB and DB>TS; and,   a box for housing the set of two trays for the brittle columnar body and the brittle columnar body supported by the two trays for the brittle columnar body.
