A spout valve assembly, for a pump dispenser including a discharge head, is located within an opening in the discharge head for permitting outletting of liquid product and includes a spout valve retained within the discharge head opening by a retainer. The spout valve includes a slit at a first end thereof and an orifice at a second opposite end thereof. The slit includes slit lips directly engageable with and disengageable from each other to respectively define slit closed and opened configurations. The spout valve is made of a material for permitting opening of the slit under pressure from the liquid product for thereby allowing the liquid product to be discharged out through the slit when in the slit opened configuration, and for otherwise permitting closing of the slit to prevent the liquid product from being discharged through the slit when in the slit closed configuration.

A manually actuated pump sprayer adapted to be mounted on a container of liquid to be sprayed upon pump actuation is provided, and includes a plunger head having a side wall containing a discharge orifice. The plunger head may be reciprocable relative to the pump sprayer. An overcap may be independently rotatably disposed on the plunger head, and include a side wall overlying the discharge orifice in a condition of non-use. The side wall may include an opening disposable in alignment with the discharge orifice upon rotation of the overcap relative to the plunger head. A container closure may be provided for affixing the plunger head and the overcap relative to the container. The plunger head may be axially reciprocable relative to the container closure and may otherwise be locked relative to the container closure when in first and second orientations.

An applicator is adapted to be mounted on a hollow piston stem of a manually reciprocable pump dispenser for applying a cleaning liquid to a fibrous article such as fabric, rug or carpet or the like from a container of liquid to which the dispenser is mounted. The applicator has a domed outer convex rigid wall with at least one discharge port in communication with the discharge passage of the piston stem, and an outer surface of the domed wall is textured for rubbing the cleaning liquid into the fibers article during a cleaning operation. An overcap is connected to a side wall of the applicator by a hinge permitting the overcap to cover the outer surface of the domed wall when not in use. And, a container closure may be provided in telescoping relationship to the applicator which is rotatable about its central axis between lock and unlock positions.

Manually actuated dispenser

A liquid pump dispenser with a discharge spout is rendered child-resistant by the provision of a hollow sleeve surrounding the pump body and engaging an upper wall of the closure cap with at least one lip at an upper end of the sleeve engaging an underside of the plunger head to immobilize the head against actuation. The sleeve is removed prior to dispensing as the lip is pulled or forced away from the head permitting upward movement of the sleeve in a direction rotatable about the head as the spout extends through a cutout in the sleeve whereafter the sleeve is slid along the spout and completely removed.
