Abstract: A tamper-evident cap construction for a dispenser, comprising a cap body having a discharge opening, a screw cap carried thereon and adapted to close off the discharge opening, and a frangible tab that is integral with the screw cap and which extends outwardly over an exposed exterior surface of the body and is integral therewith by virtue of a common fused juncture area at the surface. Preferably the fusing takes the form of a sonic weld. The tab has a transverse line of weakness which can be adjacent to either the point of attachment of the tab to the screw cap, or else to the fused area. The tab normally prevents relative turning between the screw cap and the cap body, but can rupture when a turning force is applied therebetween, having a magnitude which is less that required to separate the tab from the body at the location of the fused juncture.

Abstract: A captive dispensing cap construction for a container, comprising a body part having a discharge passage, and a stopper extending upwardly from the passage. A screw cap part is carried by the body part and has a discharge opening into which the stopper extends when the screw cap part is screwed to its full-on position. The screw cap part and body part have two pairs of mutually engageable portions, one comprising cooperable screw threads for moving the screw cap part axially on the body part as the cap part is turned, and the other comprising a cam track on the body part and a follower portion on the screw cap part. The screw threads have sufficient backlash to enable the screw cap part to have an initial unscrewing turning movement from its fully screwed-on position through an angle essentially in excess of 20.degree. before axial outward displacement of the cap part occurs.

Abstract: A non-resealable dispenser cap construction for a container, comprising a cap body part having a discharge opening, an orifice part movable between sealing and unsealing 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 when 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.

Abstract: A two-piece, twist-on, twist off closure which permits fluids to be dispensed from a container. The two-piece closure includes an insert which can be fastened to a container, a post located in the center of the insert, and a sleeve which fits onto the outside of the insert and has a hole in the center thereof for receipt of the post to form a seal therewith.

Abstract: The invention comprises a combination of a container and a child resistant liquid seal closure with a dispensing spout. The container neck has one or more locking lugs which engage one or more locking lugs on the interior surface of the closure to prevent rotational removal of the closure from the container. A snap cap is retained within the closure, adjacent the inside surface of the top panel, and provides a primary liquid seal. The snap cap is provided with a dispensing spout, which is normally closed by the outer closure. To remove the closure, or to open the dispensing spout, the closure skirt must be squeezed and distorted to disengage the closure lugs radially outwardly from the locking lugs on the container neck.

Abstract: A fluid dispenser includes an actuator containing fluid passages defining a discharge path for fluid from a supply container to a discharge orifice, a needle valve lying adjacent the discharge path, a nipple surrounding the needle valve and a nozzle cap having an end wall containing a discharge orifice and being threadedly engaged with the nipple for movement of the end wall toward and away from the valve upon cap rotation. Discharge through the orifice may be positively shut-off upon rotation of the cap which causes the valve to be seated against the discharge orifice, and the nozzle cap may be locked in an off position upon engagement between a spring biased tab provided on the actuator and an inwardly extending shoulder provided on the skirt of the cap. A ramp member on the cap includes a ramp surface and the shoulder so as to effect inward deflection of the tab upon engagement with the ramp surface during cap rotation toward the off position.
