Abstract: A system of non-reproducible locking key and cylinder for said key, which being a flat-blade type key (1) has installed a lengthwise swinging member (6) with the capacity of realizing two combined rotary movements of limited width, which are: a first perpendicular transverse movement at the bottom of said flat blade (1), a second angular sweep rotary movement which takes place in the direction of the width of said blade, movements which are produced respectively with relation to a first (7a, 7b) and second (8) axes. The swinging member (6) being located in a sectorial window (9) which runs through the thickness of the key, forming radial lateral sidewalls (9c) which extend divergently between a relatively narrower front wall (9b) located adjacent the entering end of key (1), and a relatively wider arched rear wall (9c) in opposition thereto.

Abstract: The invention is a single utensil that combines the features of a cooking vessel with those of a strainer. The invention comprises a pot having a spout. The lid for the pot has a downwardly extending skirt which includes a straining section. The lid also has locking means on the skirt which cooperate with locking means provided on the inside of the pot. In use, the lid is placed on the pot so that the straining section is not in communication with the spout. In this position, the skirt will seal the opening created by the spout. Once the cooking is done and the user wishes to drain off the excess liquid, he or she rotates the lid to align the strainer section of the skirt with the spout. When the lid is so positioned, the locking means on the skirt of the lid will engage the cooperating locking means on the inside of the pot to lock the lid in place. The pot and lid can then be lifted as a unit to drain the liquid from the pot.
