Abstract: With the subject invention, a pump is formed that generally includes a reservoir formed to accommodate at least one fluid dose, and a fluid-collecting chamber in fluid communication with the reservoir. The fluid-collecting chamber includes a dose-control portion which encompasses a volume defined by two dimensions. A first piston is disposed to urge fluid from the reservoir and at least into the dose-control portion. A second piston is disposed to reversibly slide within at least the dose-control portion of the fluid-collecting chamber. A nozzle is also provided which is located such that fluid displaced by the second piston from the dose-control portion is generally urged towards the nozzle. A check valve may be placed in the fluid path between the dose-control portion and the nozzle.

Abstract: Pump systems are provided which allow for highly-accurate dose control. The pump systems may be provided with a valve stem or a piston, either having a constant-diameter stroke portion interposed between reduced-diameter portions. At least one stationary sealing member immovably affixed to a pump body is also provided formed to sealingly engage the stroke portion of the valve stem or the piston. The sealing member is also formed to not engage the reduced-diameter portions. As such, the volume of the administered dose is controlled by the stroke length, which, in turn, is a function of the dimensioning of the constant-diameter stroke portion and the dimensioning of the sealing member. Advantageously, with the subject invention, a minimal number of tolerances can be implicated in controlling dosing volume.

Abstract: A spray dispensing head for a squeeze dispenser is disclosed. The dispensing head includes passageways for directing streams of air and liquid to a mixing chamber wherein the liquid is broken up into droplets and emitted as a fine spray through an orifice. The device includes a valve which is operated by a push-pull motion. When the valve is closed, the liquid is sealed off from the atmosphere, thus preventing drying or contamination of the liquid product.

Abstract: A dispensing head for a squeeze bottle sprayer includes a rotatable valve. The rotatable valve has both an air control notch and a fluid control notch. Upon rotation of the valve, the notches cooperate to vary the amount of air and or fluid discharged by the dispenser. The density of the stream may therefore be varied.

Abstract: A spray dispensing device is provided which can be used with non-pressurized containers. The device includes passageways for directing streams of air and, liquid where the liquid is broken up into droplets and emitted as a fine spray through an orifice. An annular air passageway is concentrically disposed around a liquid passageway, and the air is lead through air swirl passages, where the annular stream of air is given a rotary motion as the result of swirl vanes forming the air swirl passages. The velocity of air past a product passageway exit orifice also creates a Bernoulli effect which reduces pressure at that orifice, which acts to draw liquid to the spray orifice. The device may include a dip tube for the liquid which is provided with a check valve for retaining liquid at a high level in the dip tube after each spray cycle so that spraying is nearly instantaneous upon actuation.

Abstract: A pump and pump securing device, which pump securing device includes, at its axially-outer end, an axially-outer step and a axially-inner step. These steps are used to interact with a radially-projecting flange on the pump, thereby allowing the pump to be securely snapped into the mounting cup without the need for crimping. The steps also control the position of the pump relative to the mounting cup. As a result, the steps prevent the pump from compressing gaskets in the assembly, thereby controlling variations in pump dosage resulting from gasket compression. The flange can include slots creating vent paths for venting air into the container during operation of the pump.

Abstract: An improved modular lotion pump for dispensing personal products such as lotions, creams, etc., and a method of assembling same is disclosed. The modular pump is formed of several subassemblies that are subsequently assembled to form the modular pump assembly. A cap having means for attachment to a container from which material is to be dispensed may be snap fit onto the modular pump. The pump includes a rotatable locking sleeve for preventing leakage even if the container is squeezed or stepped upon by a consumer and for changing the orientation of the actuator. The actuator may be rotated relative to the locking sleeve to prevent accidental dispensing.

Abstract: A 360.degree. valve body for use with a dispenser includes a lower section of generally cylindrical shape containing therein a central first bore for accepting a dip tube and a top, an upper section of generally cylindrical shape but of smaller diameter than the first section extending from the top, with the upper section having a central second bore therein, the first bore and second bore having a common axis, with the upper section adapted to be inserted into a dispenser. A third bore is formed in the top of the bottom part adjacent the upper section and extends to first bore in the lower section and has therein a seat for a ball check valve. An arcuate recess formed in a portion of said upper part adjacent opening is used for guiding a ball at one point and first and second posts, each having an arcuate inner surface, spaced from each other and the arcuate cutout are used for guiding said ball at two other points.

Abstract: An atomizing pump dispenser which includes a valve member having a flattened top so that the diameter of the sealing area in the outlet is increased substantially. A recess within the valve member is modified to provide conical ball sealing oprtions tapered at predetermined angles to provide a tight seal between the ball and the valve member. The innermost end of an inner hollow part of the valve member is a reduced diameter portion such that the initial movement of the valve member is easier. This in effect, tricks the user's finger by easing the initiation of movement of the actuator so as to give the feel of free movement. The inner part of the valve member is provided with a molded-in slotted protrusion for breaking the seal between the valve member and a flexible annular seal, thus alleviating the creation of the vacuum caused by the seal between the ball and the ball seat.

Abstract: A pump for use with a container of liquid material for dispensing and or atomizing the liquid material in an accurate dose. The apparatus has a movable valve member which is normally biased in a closed position. Upon actuation of the pump, a fluid pressure is caused to act upon the valve member. The ratio of the area of the valve member against which the pressure acts before and after opening of the valve member is selected to be at least 1:1.5, to cause a corresponding reduction of the force necessary to open the valve and dispense the fluid upon actuation, resulting in a full stroke and single puff each time.
