A stopper for an opening of a container such as a thermos. The stopper includes a pushbutton, a fluid flow channel extending between an inlet and an outlet, and a movable plug portion positioned adjacent the inlet. A biasing member biases the plug portion into sealing engagement with the inlet thereby preventing the contents of the container from flowing into the channel. A cam follower is disposed upon a cam surface opposing the biasing member. The cam follower is rotatable by the pushbutton relative to the cam surface from a closed position to an open position and when so rotated, exerts a biasing force on the cam surface sufficient to overcome the biasing force exerted by the biasing member on the plug portion and space the plug portion from the inlet allowing the contents of the container to flow into the channel and out the outlet.

The present invention relates generally to a container that may be sealed and reclosed with a threaded closure. More specifically, the present invention relates to methods of manufacturing a metallic container having an opening with inwardly facing threads that are formed after a threaded closure is inserted at least partially into the opening. The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads.

A method and apparatus for metering a liquid nutritional supplement provides a liquid dispenser having a body that contains a predetermined number of single dosages of the liquid nutritional supplement, a cap, such as a child-resistant cap, coupled to a neck portion of the body, and a dosage cup coupled to the cap. The dosage cup has at least four axial shoulders on an inside surface thereof that each has an engaging surface adapted to engage axial ridges of the cap. The dosage cup is coupled to the cap such that a force that is greater, by a predetermined amount, than the weight of the dosage cup is required to remove the dosage cup from the cap, and providing the dosage cup with an indicator adapted to indicate one of the single dosages of the liquid nutritional supplement to be consumed by a user for a predetermined time period.

An object is to provide a container sealing device which can perform an opening of an inner plug with a clear opening feeling. An inner plug 10 is assembled in advance to an upper closure 20 by using a second screwing part 52. At this time, since an assembling interval between a separation part 12 and the upper closure 20 can be adjusted by tip end parts 16t and 20u of a cylindrical part 16 which are first stoppers and the small-diameter cylinder part 20d, the second screwing part 52 can be brought into a lock state of being screwed to the deepest position or a state close to that. In opening the plug, the first screwing part 51 is loosened the second screwing part 52 is tightened, and the separation part 12 can be rapidly and reliably separated from a body part 10b of the inner plug 10.

A closure for a container-and-closure sealing system embodied in a container and closure package, and method of making the same. The container has an open mouth surrounded by a cylindrical neck wall having internal threads and an open upper edge. The closure is a cap / dispensing cup type and has a skirt with external threads adapted for threaded receipt within the container neck wall. A circumferentially continuous flange projects outwardly from the skirt and has a conical portion adapted for cam engaging, trapping and sealing with the open upper edge of the neck wall as the closure is threaded into this wall. The closure skirt also has a circumferentially continuous plug-type sealing surface that extends radially outwardly from the skirt between the trapping flange and closure external threads adapted for interference sealing engagement with the neck wall as the closure is threaded thereinto. The materials of the closure and container may differ in hardness relative to another so that either the plug seal rib of the juxtaposed neck wall surface deforms under closure / container engaging forces to thereby enhance the sealing capability and life. The flange has a conical skirt wall portion integrally dependent from a flange radial wall portion that is adapted to sealing cam wedge embrace the neck open upper edge and creates increasing squeeze force as the closure is threaded into the neck wall. A concentrically intermediate annular seal is also provided in the form of V-rib or liner material interposed in assembly between the container upper edge and the flange radial wall portion. The container neck wall may have a circumferentially continuous internal groove disposed between the neck internal threads and open upper edge for receiving the closure plug seal rub by interference snap fit when the closure is threaded into the wall and reaches closed position thereon to thereby enhance removal torque capability.

A rotatable securing device for a tool box has a casing, a securing unit and a locking unit. The casing has a locking recess, the locking recess is provided with an opening at a middle area, and a plurality of engaging grooves and a first contacting face are evenly disposed on a circumference of the locking recess. The securing unit respectively has a supporting surface at an upper end and a lower end, and a fastening rib respectively disposed at two sides of the two supporting surfaces. The locking unit is a flat disk; the locking unit has an engaging face corresponding to the fastening rib, a plurality of positioning protrusions disposed on its edge, at least one the elastic slot adjacent to the positioning protrusion, and a second contacting face for in contact with the supporting surface.
