  • Publication number: 20130026196
    Abstract: The invention relates to a spill proof self-closing flow control device (SCFCD) with adjustable actuator element for flexible or rigid containers with fluids. The SCFCD comprises a spout, a flexible valve-retaining element and a container closure element. The valve-retaining element is a one-part component consisting of an actuator element, a cylindrical valve holder and a valve for alternately opening and closing the flow-through orifice. In the various embodiments two or three pressure chambers are formed with pressures P1, P2 and P3 controlling the flow control device, separated by the valve-retaining element. In a first, second and fourth embodiments the actuator element is configured to move in the downstream direction by an under pressure in the first chamber thereby bringing the valve in the open position, while in a third embodiment, the actuator element opens the valve in the upstream direction.

  • Publication number: 20120325769
    Abstract: An integral seal opening means within a sport closure cap for containers, in which a tamper evident seal with a reinforced rim secures the mouth opening. The closure cap holds a minimum of three protrusions, extending towards the seal, each having cutting edges of which the lower one is at a smaller radius. These protrusions engage with the tamper evident seal, when the cap is rotated clockwise, thereby cutting off part of of the seal rim and at the same time cutting three banana shape slots in the seal. For single serve beverage bottles with tamper evident seal and a sport closure, there is no need to unscrew the cap for opening the seal and getting access to the beverage. Initially the reinforced rim is used to prevent protrusions from accidently opening the bottle seal. The opened seal remains in place while the sport closure is held onto the bottle.
