Container body and recyclable truncated- cone - shaped drum

Abstract

A truncated-cone-shaped container body for a truncated-cone-shaped drum for packaging has an upper edge delimiting an upper inlet mouth. The upper edge has a first folded portion projecting outwardly with respect to a lateral wall of the truncated-cone-shaped container body. The first folded portion is in one piece with the lateral wall. The first folded portion serves as a support for a lid and allows stackability of a plurality of drums one inside the other. The truncated-cone-shaped container body is made of kraft fibre. A truncated-cone-shaped packaging drum has the truncated-cone-shaped container body, a bottom, a lid, and a clamping collar for fastening the lid to the truncated-cone-shaped container body.

What is claimed is: 
     
         1 . A truncated-cone-shaped container body for a truncated-cone-shaped drum for packaging, the truncated-cone-shaped container body developing along and around a development axis with a lateral wall that defines an internal volume extending between an upper inlet mouth delimited by an upper edge and a lower opening,
 wherein the upper edge comprises a first folded portion which projects outwardly with respect to the lateral wall, on an opposite side with respect to the development axis the first folded portion being in one piece with the lateral wall and suitable for acting as a stop for supporting a lid.   
     
     
         2 . The truncated-cone-shaped container body of  claim 1 , wherein the first folded portion is made of a same material as the lateral wall. 
     
     
         3 . The truncated-cone-shaped container body of  claim 1 , wherein the lateral wall is uniform and free of discontinuities. 
     
     
         4 . The truncated-cone-shaped container body of  claim 1 , wherein the upper inlet mouth defines a larger base of the truncated-cone-shaped container body delimited by the lateral wall, and the lower opening defines a smaller base of the truncated-cone-shaped container body. 
     
     
         5 . The truncated-cone-shaped container body of  claim 1 , comprising a lower edge that delimits the lower opening, the lower edge comprising a second folded portion which projects inwardly with respect to the lateral wall, that is, facing the development axis. 
     
     
         6 . The truncated-cone-shaped container body of  claim 5 , wherein the second folded portion is suitable for acting as a stop for supporting a disc-shaped bottom and for generating an interlocking together with the lateral wall to stably fasten the disc-shaped bottom to close the lower opening. 
     
     
         7 . The truncated-cone-shaped container body of  claim 5 , wherein the second folded portion is in one piece with the lateral wall. 
     
     
         8 . The truncated-cone-shaped container body of  claim 5 , wherein the second folded portion is made a same material as the lateral wall. 
     
     
         9 . A truncated-cone-shaped drum for packaging comprising:
 a truncated-cone-shaped container body developing along and around a development axis with a lateral wall that defines an internal volume extending between an upper inlet mouth delimited by an upper edge and a lower opening, wherein the upper edge comprises a first folded portion which projects outwardly with respect to the lateral wall, on an opposite side with respect to the development axis, the first folded portion being in one piece with the lateral wall and suitable for acting as a stop for supporting a lid;   a bottom applied at the lower opening of the truncated-cone-shaped container body;   a lid applied at the upper inlet mouth of the truncated-cone-shaped container body, resting on the first folded portion; and   a clamping collar suitable for fastening the lid to the truncated-cone-shaped container body.   
     
     
         10 . The truncated-cone-shaped drum of  claim 9 , wherein the bottom is disc-shaped. 
     
     
         11 . The truncated-cone-shaped drum of  claim 9 , wherein the bottom is made of wood or cardboard. 
     
     
         12 . The truncated-cone-shaped drum of  claim 9 , wherein the lid is disc-shaped. 
     
     
         13 . The truncated-cone-shaped drum of  claim 9 , wherein the lid is made of wood or cardboard. 
     
     
         14 . The truncated-cone-shaped drum of  claim 9 , wherein the clamping collar comprises an annular element suitable for surrounding the upper edge of the truncated-cone-shaped container body and an opening and closing means for bringing the clamping collar into an open configuration in which the annular element is widened and allows a separation of the lid from the truncated-cone-shaped container body, and into a closed configuration in which the annular element is tightened around the lid resting on the first folded portion and generates a clamping of the upper inlet mouth. 
     
     
         15 . The truncated-cone-shaped drum of  claim 14 , wherein the annular element has a C-shaped cross-section and is suitable for peripherally overlapping the first folded portion and the lid resting on the first folded portion, and to contain both the first folded portion and the lid within its thickness to generate the clamping of the upper inlet mouth. 
     
     
         16 . The truncated-cone-shaped container body of  claim 1 , wherein the truncated-cone-shaped container body is made of kraft fibre.
