Title:
IMPACT-RESISTANT ENVELOPE
Document Type and Number:
WIPO Patent Application WO/2010/101232
Kind Code:
A1
Abstract:
Disclosed is an impact-resistant envelope which can function as an envelope having impact resistance when used with an article accommodated therein, but the volume occupied by the envelope when said envelope is not being used, such as during transportation or storage, can be reduced by making the impact-resistant members assume the form of sheets. The impact-resistant envelope is provided with an external bag formed by paper having an insertion aperture at one end and a fixed bottom at the other end, and two sheets formed by paper which can be accommodated inside this bag. A metal expandable slit element is provided within these two sheets parallel with the open end of the envelope. Also, one side thereof is fixed at the aperture end of the bag, and the sides opposite to this first-mentioned side are fixed together. The dimensions of the sheets in the direction perpendicular to the slit are smaller than the internal dimensions of the bag in the same direction, so that an envelope having impact resistance is constituted only in use.
