Polygonal sliding packaging with twist-and-push movement for opening and closing

摘要

Polygonal sliding packaging having an inner hollow body (3) which slides telescopically within an outer hollow body (2) to form a variable length container which uses a twist-and-push or pull movement for closing and opening. The two hollow bodies are latched using assigned latchways (13-2 to 13-3), which are at least a first row of notches (6, 7) with at least one latch notch (5) disposed on one hollow body (3) and at least a second row of notches (9 through 12) with at least one latch notch (8) disposed on the other hollow body (2). Latchways are disengaged by twisting the two hollow bodies counter to one another about their longitudinal axes so that the latch notches of one latchway (13-3) reside within at least one slideway (14-2, 15-2), which is disposed on one hollow body (2) in a circumferential direction at a distance from the at least one latchway (13-2).

主权项

1. Packaging that has an adjustable length, said packaging comprising:
a first body having an outer surface and an inner surface that is oppositely disposed from said outer surface to define a wall between said outer surface and said inner surface, said wall defining a first polygonal profile and being located circumferentially around a longitudinal axis of said first body; a second body that also has an outer surface and an inner surface that is oppositely disposed from said outer surface to define a wall between said outer surface and said inner surface, said wall of said second body defining a second polygonal profile that is different from said first polygonal profile and being located circumferentially around a longitudinal axis of said second body, said second body being engaged with said first body at times when the longitudinal axis of the second body is substantially parallel with the longitudinal axis of said first body and at least a portion of the outer surface of the wall of said second body faces at least a portion of the inner surface of the wall of said first body; a latchway having at least one row of engagement elements, said latchway being located on at least one of the outer surface of the wall of said second body or the inner surface of the wall of said first body; at least one latch member that is located on the other of said outer surface of the wall of said second body or the inner surface of the wall of said first body from said latchway; and at least one slideway that is defined by a gap between the outer surface of the polygonal wall of the second body and the inner surface of the polygonal wall of said first body at times when said latch member engages said latchway, said slideway being positioned circumferentially apart from at least one latchway or from at least one latch member, said first body being moveable in the circumferential direction with respect to said second body between a locked position wherein said at least one latch member said latchway to lock the longitudinal position of said first body with respect to said second body, and a displacement position wherein the polygonal wall of said first body is twisted against the polygonal wall of said second body to place said latchway or said at least one latch member in said at least one slideway and disengage said at least one latch member from said latchway to unlock the longitudinal position of said first body with respect to said second body such that said latchway or said at least one latch member is longitudinally moveable in said slideway and said first body is longitudinally moveable with respect to said second body, wherein the at least one slideway is disposed adjacent at least one corner of the outer surface of the wall of the second body.
