Abstract: There are provided a system and a method for implementing a normally-closed but openable closure device (20) for a fluid-retaining container (10) having a container orifice (11). The closure device prevents unintentional spilling of substance out of an opening, which is disposed in fluid communication with the orifice, by urging a lid (32) to seal the opening closed. For retrieval of substance out of the container, a member of a flow control implement, such as pertaining to a faucet (60) for example, is introduced into the closure device. The introduction of the implement forces the lid open, and allows retrieval of substance out of the container.

Abstract: A safety device for a liquid-containing vessel for preventing accidental spilling of the liquid contained in the vessel, the liquid having a rest level. The safety device comprises a lid assembly having a lower partition, the partition dividing the vessel into a first lower liquid containing portion and a second upper portion empty from liquid and having a second liquid opening, the lower partition comprising a movable flap and a first liquid opening that is located lower than and below the second liquid opening in an upright position of the vessel, the flap having positive magnetic attraction with the first liquid opening and being configured to seal the first liquid opening against passage of the liquid. In an upright position of the vessel, the entire safety device is located higher than and above the rest level of the liquid and the flap is normally open with respect to the first liquid opening.

Abstract: A smart electronic authorization/credit card called a Smart Key Card (SKC) and a method for its operation are provided. The SKC includes a keypad for entering data, a magnetic strip or a Smart Card Chip which stores confidential information, a battery, NVM memory that stores program code and data, a CPU and a Smart Key Card hybrid chip. The SKC is activated by the authorized user for a predetermined time period. The method for operating the SKC includes entering a secret code through the keypad on the SKC, comparing the entered secret code to a true code stored in the SKC, and activating the SKC for a predetermined time period, when the entered secret code and the true code are the same. The data stored in the SKC can be modified by a user using the keypad and a display on the SKC.
