Zero-clearance packaging for elongate objects
View Patent ↗A zero-clearance packaging for elongate objects, in particular, elongate objects subject to fracture, comprises a packaging sleeve with internal and external parts with a closure disposed therebetween which makes it possible to push the parts together in telescope fashion and to hold the same in particular closed position, wherein at least one elastic tension structure is disposed in at least one of the parts, which stricture prestresses the parts in a closure direction of the packaging against the object stored in the packaging. The elastic tension structure comprises bellows formed by an axial pail of the wall of the parts.
1. A zero-clearance packaging for elongate objects, said packaging comprising a packaging sleeve having:
an internal part having an interior wall;
an external part that receives said internal part in the direction of a longitudinal axis, said external part also having an interior wall;
a closure that is disposed between said internal part and said external part, said closure being capable of pushing said internal part and said external part together in a telescopic fashion in the direction of the longitudinal axis with the internal part being received in the external part and holding said internal part and said external part in a closed position; and
at least one elastic tension structure that is disposed over an axial length of said external part, over an axial length of said internal part, or over an axial length of both, wherein said at least one elastic tension structure has a length that is variable in the direction of the longitudinal axis such that the elastic tension structure elongates in the direction of the longitudinal axis at times when said closure urges said internal part and said external part together in a telescopic fashion while the interior wall of said internal part contacts one end of said elongate object and the interior wall of said exterior part contacts another end of said elongate object such that the interior walls of said internal part and said external part are placed in tension across said elongate object
wherein said elastic tension structure comprises a wall of said internal part, a wall of said external part, or a wall of said internal part and said external part, said wall being constructed as bellows over at least a particular axial length.
2. A packaging sleeve according to claim 1 , wherein a wall construction of said external part and/or said internal part of said packaging sleeve is constructed as said elastic tension structure that elongates in the direction of longitudinal extension of said packaging sleeve.
3. A packaging sleeve according to claim 2 wherein said closure is self-retaining and/or a latch type.
4. A packaging sleeve according to claim 3 , wherein said closure is a self-retaining threaded screw closure.
5. A packaging sleeve according to claim 3 , wherein said closure is a latching bayonet closure.
6. A packaging sleeve according to claim 5 , wherein said bayonet closure achieves a closure of said packaging by facilitating a retention-free and resistance-free torsion between said external part and said internal part, and wherein opposed parts of said bayonet closure comprise bevels on one of said parts that meet corresponding insertion bevels on the other of said parts.
