  • Patent number: 7886941
    Abstract: 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.

  • Patent number: 7870977
    Abstract: A dispenser for use with a liquid product including beads which are rupturable to release additives when rubbed between the hands of a user. The dispenser includes a discharge head reciprocable between pressure and return strokes, and a valve assembly for respectively allowing and preventing liquid product from being discharged during the pressure and return strokes. The valve assembly includes ribs for guiding movement of a check valve disposable in respective valve open and closed positions in which the check valve is disposed out of and in contact with a valve seat. The valve assembly includes primary fluid passages for permitting passage of the liquid and beads into a pump cylinder, and secondary fluid passages for permitting displacement of the beads during translation of the check valve between the valve open to the valve closed positions for thereby preventing accumulation of beads between the check valve and its valve seat.

  • Patent number: 7178694
    Abstract: 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.

  • Patent number: 5230648
    Abstract: A foam dispensing doll includes a head and body coupled together at a neck joint and defining an interior cavity therein. A generally cylindrical canister sleeve is supported within the doll body and head cavity and extends through a passage formed in the neck joint. The canister sleeve defines a closed end within the doll body and an open end extending upwardly through an aperture formed in the doll head. A generally cylindrical soap canister having a quantity of pressurized soap foam stored therein includes an upwardly extending pivotable valve. The cylindrical soap canister is received within the canister sleeve such that the valve extends upwardly beyond the doll's head.
