The upper end of each top leg (7) is pivotably coupled to the top leg connector (8) of the top vent frame.

This bendable apparatus includes a top bracket and a bottom bracket which is rotatably axle-joined with the top bracket.

The lower tab fits within the base and the upper tab rests on the corresponding shoulder of the upper member.

The top flap, bottom flap, and opposing side panels are adapted to interconnect to secure items in the envelope.

Each locking mechanism includes an upper leg and a lower leg, each upper leg and the lower leg having a proximal end and a distal end.

A top locking tab (38) is connected to the top closure flap (26).

The fastener elements (31) are each provided with an engagement head (31a), an upper leg (31b), a lower leg (31c), and a connection section (31d).

A knob lock (4, 6) extends from either side of the top locking tab (38).

The top locking tab (38) is folded at angle for insertion into the internal space.

A hook, extending upward from the upper leg and away from the lower leg, allows the hanger to be placed on a support structure, such as a rod.

The invention includes a rigid upper tab having a peg adapted for interaction with a robot arm of an automated process.

The fastener elements (31) of at least one of the first and second fastener element rows (30A, 30B) are each provided with a stepped section (31e) which is provided to the upper leg (31b) so as to be recessed toward the lower leg (31c).

The top enters the bottom from behind, with the bottom’s top leg elevated to allow for entry.

The lower end of the central post (5) is fixed on the central connector (4) located on the top center of the frame body and the upper end thereof is fixed on the top leg connector (8) located on the top vent frame.

Some of the leg parts are bent toward the top so as to form upper leg parts.

The height of the upper grip is adjustable by raising or lowering an extension rod that passes through a dynamic seal to the environment outside the chamber.
