An object to be packaged is positioned and secured on a set rack, and the set rack is placed on a buffer material provided on a bottom plate of an inner packaging cover. Right/left cover portions of the inner packaging cover are folded up at folding lines so that the inner packaging cover covers the set rack, and the set rack is placed on a bottom panel of the outer packaging case with the inner packaging cover therebetween. Thereafter, an open/close panel is slid along a guide groove formed on a side opening of the outer packaging case so as to close the side opening by the open/close panel, and an upper opening is covered by a top plate panel to thereby store the object to be packaged in the outer packaging case using the inner packaging cover and the set rack.

Reusable container

A slip-out preventive unit of a supply exhaust pipe assembly with a supply exhaust pipe forming a faucet at one end and forming an insertion port at the other end. The faucet having a cut window to allow the lock portion of a lock member to pass through the faucet to engage a circumferential groove of the insertion port. A slip-out prevention unit of which the lock member is a component, to guide and constrain the lock member to engage the circumferential groove, resulting in the holding of the insertion port within the faucet preventing unwanted separation after connection of the assembly. A slide guide allows movement of the lock member in an axial direction of the faucet where the tip of the lock member may be constrained from radial movement of the engagement portion of the lock member by a locking bag wall upon an attempt to separate the insert portion from the faucet. The insert portion being insertable and removable of the faucet when the lock member is in a withdrawn position relative to the locking bag wall, thus allowing the engagement portion of the lock member to be radially displaced by the end of the insertion port or the slope of the circumferential groove of the insert port as it is inserted or removed from the faucet respectively. The locking member being moved to its withdrawn position either by direct force acting upon the lock member from the insertion port as it is inserted into the faucet for connection of the unit, or by an external operator applied force against the lock member prior to removal of the insertion port from the faucet.

The installation of a fire retarding division-penetrating member is enhanced and the member fits the outer circumference of inconstant penetrating material to prevent the filler from dropping. The heat expansion fire resistant material may be securely provided. A tongue piece (,) of fire resistant material (,) may fit to the surface and valley of pipe (,) and cable (,) only by fitting the saw teeth state heat expansion fire resistant material (,) with its upper face being covered with the sheet (,) inside the holding frame (,) of sleeve main bodies (,) and (,) that are split into two pieces and by dropping these sleeve main bodies (,) and (,) into the floor through-hole (,) from above. In this way, the filler like mortar (,) and so forth can be immediately filled from the upper floor with no need for repairing the heat expansion fire resistant material (,). Further, the heat expansion fire resistant material (,) securely functions with the heat during a fire disaster, blocks the floor through-hole (,) and prevents the flames, heat, smoke, etc. from invading into the upper floor and the lower floor.

Fire retarding division penetrating member

An elastic metal sheet member with thermal expansion material being lined on its internal face is curved to a C-letter shape. A claw is formed downward to a opening side tip, and a engaging mouth is formed to the opposite opening side tip. In this structure, the penetrating member can be fitted to the piping 'A' or can be detached from it only by pressing the elastic metal sheet for its contraction in diameter with one hand.
