Container with walls that can be lowered made up of one, sole piece, consisting of the base (3) and four side walls (1 and 2), which are joined to the former by means of contracting strips (4) which act as hinges and therefore, allow the walls to be lowered. The edge of each side wall is in the form of an inward facing column (5) of a crenellated form, with cylindrical protrusions so that when, the columns (5) of two side walls (1 and 2) meet the, protrusions come together in such a way that the hinge pin (9) can be inserted in the axial openings (8) thereby, allowing for the container to be mounted.

Why it's free to use
- Filed November 14, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 14, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 14, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
