ABSTRACT A non re-sealable dispenser cap construction for a container, comprising a cap body part having a discharge opening, an orifice part movable between sealing and un- sealing positions and adapted to selectively seal off the discharge opening, and means for preventing re-closing of the cap construction following an initial dispensing operation. There are provided cooperable camming surfaces on the cap body and orifice parts, which tend to hold the latter part in a sealing position, as during shipping. A one-way-drive thread is provided, functioning when the orifice part is turned in an unscrewing direction, but being inoperable with the orifice part is thereafter turned in a screwing-on direction. Interference shoulders prevent the orifice part from returning to its sealing position, following an initial discharge. The advantage of the present construction over the devices of the prior art is that once the orifice part is moved from its fully on or sealing position, it cannot normally be returned, and thus there is prevented re-sealing of the container and possible subsequent risk or danger of pressure build up therein.
