Writing Implement Case With Concealed Connecting Seam

Abstract

A container for receiving at least one writing implement, wherein the container has at least one wall (W) element which is made from a flat material, wherein, when the container is in the finished condition, the one side of the wall element (W) forms a container inside and the other side forms a container outside and wherein at least a part of its edges the wall element (W) has a first connecting portion ( 30 ) whose edge part is angled with respect to the plane of the flat material of the wall element ( 30 ). It is further provided that at least a part of its edges the wall element (W) has a second connecting portion ( 32; 34 ) which is of a congruent configuration with respect to the first connecting portion ( 30 ) in such a way that when the first connecting portion ( 30 ) is connected to the second connecting portion ( 32; 34 ) to form at least a part of the container wall the edge part of the first connecting portion ( 30 ) is covered over with respect to the outside of the container wall.

1 . A container for receiving at least one writing implement, comprising at least one wall element (W) which is made from a flat material, wherein, when the container is in the finished condition, the one side of the wall element (W) forms a container inside and the other side forms a container outside, wherein at least a part of its edges the wall element (W) has a first connecting portion ( 30 ) whose edge part is angled with respect to the plane of the flat material of the wall element (W) and wherein the first connecting portion ( 30 ) is welded (connected by joining of the materials involved) to the second connecting portion ( 32 ;  34 ),  
     wherein the edge part of the first connecting portion ( 30 ) is angled at least approximately through 90° with respect to the plane of the flat material of the wall element (W) towards the outside of the finished container and that at least a further part of its edges the wall element (W) has a second connecting portion ( 32 ;  34 ) which is designed in matching relationship with respect to the first connecting portion ( 30 ) in such a way that when the first connecting portion ( 30 ) is connected to the second connecting portion ( 32 ;  34 ) to form at least a part of the container wall the edge part of the first connecting portion ( 30 ) is covered with respect to the outside of the container wall.  
   
   
       2 . A container as set forth in  claim 1 , wherein the second connecting portion forms a Z-shaped stepping ( 34 ) out of the plane of the flat material, the depth of which is at least equal to and preferably greater than the height of the angled configuration of the edge part of the first connecting portion ( 30 ), with respect to the plane of the flat material of the wall element (W).  
   
   
       3 . A container as set forth in  claim 2 , wherein the free edge portion of the Z-shaped stepping ( 34 ) extends at least approximately parallel to the plane of the flat material of the wall element (W).  
   
   
       4 . A container as set forth in  claim 3 , wherein at least one of the two angles of the Z-shaped stepping ( 34 ) is at least approximately 90°.  
   
   
       5 . A container as set forth in  claim 1 , wherein the second connecting portion is an outward curvature portion ( 32 ) which extends towards the outside of the wall element (W) and the depth of which is at least equal to and preferably greater than the height of the angled configuration of the edge part of the first connecting portion ( 30 ) with respect to the plane of the flat material of the wall element (W).  
   
   
       6 . A container as set forth in  claim 5 , wherein the outward curvature portion ( 32 ) is in cross-section at least approximately in the shape of a segment of a circle.  
   
   
       7 . A container as set forth in  claim 5  or  claim 6 , wherein the outward curvature portion ( 32 ) at its free end region extends at least approximately parallel to the plane of the flat material.  
   
   
       8 . A container as set forth in  claim 1 , wherein characterized in that there is provided a single wall element (W) for forming the container, wherein the first connecting portion ( 30 ) is provided at least one first edge of the wall element (W) and the second connecting portion ( 32 ;  34 ) is provided at a second edge in opposite relationship to the first edge at least in portion-wise manner.  
   
   
       9 . A container as set forth in  claim 1 , wherein there is provided a single wall element (W) for forming the container, wherein the first connecting portion ( 30 ) is provided at least a first edge of the wall element (W) and the second connecting portion ( 32 ;  34 ) is provided at a second edge, which is in adjoining relationship in the longitudinal extent of the wall element (W), at least in portion-wise manner.  
   
   
       10 . A container as set forth in  claim 1 , wherein characterized in that the at least one wall element (W) is formed by a film.  
   
   
       11 . A container as set forth in  claim 10 , wherein the film is a deep-drawing film.  
   
   
       12 . A container as set forth in  claim 1 , wherein characterized in that the thickness of the wall element (W) is between 200 and 400 μm.  
   
   
       13 . A container as set forth in  claim 1 , wherein characterized in that the at least one wall element (W) is of plastic material.  
   
   
       14 . A container as set forth in  claim 13 , wherein the at least one wall element (W) is of PET or PVC.  
   
   
       15 . A container as set forth in  claim 1 , wherein there is provided at least one bending hinge ( 22 ,  24 ,  26 ,  28 ) for folding of the wall element (W).
