Protective packaging box

Abstract

The invention concerns a protective sleeve ( 1 ) for objects ( 10, 10 a, 10 b, 10 c ), e.g., for packaging of knives, saws, tongs, or operating instruments or the like, each exhibiting a rear handle or grip area in the manner of a non-protective area ( 15 ) and a front hazard area ( 11 ) to be protected against grasping which is insertable into the front side opening ( 4 ) open at least on one side of the protective sleeve ( 1, 1 a, 1 b, 1 c ) and is surrounded there by a receiving space ( 2, 3, 8 ), wherein the protective sleeve ( 1, 1 a - 1 c ) exhibits at least one restraining area ( 5 ), which secures the inserted object ( 10, 10 a, 10, 10 c ) against longitudinal movement in the protective sleeve and is elastically deformable and to be opened by manual force.

What is claimed is: 
     
         1 . Protective sleeve ( 1 ) for objects ( 10 ,  10   a,    10   b,    10   c ), e.g., for packaging of knives, saws, tongs, or operating instruments or the like, each exhibiting a rear handle or grip area in the manner of a non-protective area ( 15 ) and a front hazard area ( 11 ) to be protected against grasping which is insertable into the front side opening ( 4 ) open at least on one side of the protective sleeve ( 1 ,  1   a,    1   b,    1   c ) and is surrounded there by a receiving space ( 2 ,  3 ,  8 ), characterized in that protective sleeve ( 1 ,  1   a - 1   c ) exhibits at least one restraining area ( 5 ), which secures the inserted object ( 10 ,  10   a,    10 ,  10   c ) against longitudinal movement in the protective sleeve and is elastically deformable and to be opened at least by manual force. 
     
     
         2 . Protective sleeve according to  claim 1  characterized in that at least in the insertion area of the protective sleeve ( 1 ) one or more restraining elements ( 9 ,  27 ,  27   a,    27   b,    27   c ) are arranged that interact with assigned counter elements ( 13 ,  14 ) on the object ( 10 ,  10   a,    10 ,  10   c ) to be secured and held, and that the restraining area ( 5 ) is formed as an elastically deformable restraining contour ( 16 ,  16 ′,  31 ), upon activation of which the restraining elements ( 9 ,  27 ,  27   a,    27   b,    27   c ) of the protective sleeve ( 1 ) arranged in the restraining area ( 5 ) can be disengaged from assigned counter elements ( 13 ,  14 ) on the object ( 10 ,  10   a,    10   b,    10   c ) to be held. 
     
     
         3 . Protective sleeve according to  claim 1  or  2  characterized in that the restraining elements ( 9 ,  27 ,  27   a,    27   b,    27   c ) arranged on the upper free end of the protective sleeve ( 1 ) are arranged opposingly and aligned with each other on the sidewalls ( 2 ) of the protective sleeve ( 1 ) in an elastic deformation area ( 31 ) of the protective sleeve ( 1 ), which connects to the front side opening ( 4 ) of the protective sleeve ( 1 ). 
     
     
         4 . Protective sleeve according to at least one of the  claims 1  to  3  characterized in that the restraining elements ( 9 ,  27 ,  27   a,    27   b,    27   c ) on the one sidewall ( 2 ) of the protective sleeve are in mirror symmetry and aligned with the same restraining elements on the opposing sidewall ( 2 ). 
     
     
         5 . Protective sleeve according to at least one of the  claims 1  to  3  characterized in that the restraining elements ( 9 ,  27 ,  27   a,    27   b,    27   c ) are arranged only on the one sidewall ( 2 ) of the protective sleeve and on the opposing sidewall ( 2 ) are either absent or differently formed. 
     
     
         6 . Protective sleeve according to at least one of the  claims 1  to  5  characterized in that on the end of the protective sleeve ( 1 ,  1   a,    1   b,    1   c ) exhibiting the front side opening ( 4 ) a protective cap ( 6 ) can be pushed or latched or screwed. 
     
     
         7 . Protective sleeve according to at least one of the  claims 1  to  6  characterized in that the restraining elements ( 9 ) are formed as inwardly facing, aligned, and opposing nubs, ribs, or the like. 
     
     
         8 . Protective sleeve according to at least one of the  claims 1  to  7  characterized in that for manual activation of the deformation area ( 31 ) of the protective sleeve ( 1 ) diametrically opposed handle recesses ( 32 ) are arranged in the deformation area ( 31 ) of the protective sleeve ( 1 ). 
     
     
         9 . Protective sleeve according to at least one of the  claims 1  to  8  characterized in that counter elements ( 13 ,  14 ) arranged on the object are formed as stop surfaces ( 23 ,  30 ) and/or undercuts ( 24 ).
