Abstract: A plastic squeeze bottle has a dispensing end having a central, closed-ended, cone-shaped portion which serves as a stem or core for a valve assembly which includes an elastomeric seal which overlies and resiliently grips and circumferentially seals around the stem. The seal also covers apertures in the bottle end adjacent the stem. A small central aperture in the seal where it overlies the closed end of the stem, enables dispensing contents from the bottle when the bottle is squeezed, as the resulting internal pressure causes the seal to balloon slightly away from the stem and permit passage of saline solution from the bottle through the bottle end apertures and seal central aperture. When the squeezing stops, the seal resiliently retracts against the stem and closes the bottle. A snap-on overcap assembly has seal control and closure maintenance features to avoid accidental dispensing of bottle contents due to unintentional squeezing of the bottle when the overcap is closed.

Abstract: Apparatus and method for containing and feeding particulate material tending to pack into a mass from an elongated hopper having opposed sloping walls converging downward and inward towards each other to terminal margins presenting between them an elongated laterally restricted outlet for directing material onto a conveyor below. Gates are provided to close the outlet for containing the material and to open the outlet to discharge it onto the conveyor belt. Baffles within the hopper are provided to divide the cargo at a level spaced above the outlet into several piles which merge above and below the outlet. In this way the material is channelled to the outlet so that lateral arches which may be formed in the material are prevented or broken up to assure feeding. Pressure may be relieved on some of the piles by flanges extending laterally of the baffles. The invention also includes the combination of gates equipped to break up longitudinal arches with baffles to prevent the formation of lateral arches.

Abstract: A pour spout for a paperboard container of either the flat top or gable top type. In one embodiment, a rectangular strip of a rigid plastics material, such as high density polyethylene, is provided with two upwardly liftable, coplanar hinged flaps, integrally formed with the strip. The flaps are aligned with respective vent and pour openings pre-cut in the container top. Upon lifting the flaps from the plane of the strip, an extruded barrier layer (typically a polymer-foil laminate) spanning the pre-cut openings is ruptured and is carried upwardly through the die-cut openings. One opening is a dispensing opening and the other a vent opening. In a second embodiment, a single integral, coplanar and also liftable flap on the rigid strip is employed to define a single pour opening. In a third embodiment, a single integral and copolanar flap on the rigid strip is covered by a flexible strip which is peeled back to expose the flap. The flap is then pushed downwardly to define a single pour opening.

Abstract: A portable liquid dispenser for dispensing one of two liquids from a single vessel has a base with first and second separate horizontally disposed compartments separated by a liquid-impermeable barrier, a neck secured to the base and mounting handle, a valve assembly including first and second valve elements rotatably mounted in the neck for swinging between open and blocking relationship with the compartments and a valve seat in snap-fit relationship with the valve assembly.

Abstract: A material spreader system includes an elevated bridge for spanning a section of plastic concrete. A spreader including a hopper having an elongated rectangular slot is translated back and forth across the bridge to dispense a widthwise stream of topping material onto the underlying surface. Vibration generating elements are coupled at spaced apart intervals to the spreader hopper to provide for a uniform flow of topping material to the slot. A flow control device spans the length of the slot to dispense a continuous stream of topping material from the slot. A rotating metering device meters the flow of topping material through the slot. A motor translates the spreader back and forth across the bridge and rotates the rotating metering device as the spreader moves such that sequential translations of the spreader across the bridge followed by sequential translations of the bridge along the length of the plastic surface covers the entire surface with a uniform blanket of topping material.

Abstract: A container is provided which has a meniscus shape. A convex part is received in the pale of a user's hand, and a lid is forced into a concave region to dispense material stored in the concave region. An opening which is easily opened and closed for dispensing material is made by using a dispensing aperture and a projection. When the projection is forced into the aperture, the container is closed, and when the projection is removed, the aperture is opened to allow material to be dispensed. Manipulation of the projection is simplified by the use of a lever easily engaged by a user's thumb. Dispensing is accomplished by holding the device in a user's palm so that the convex part lies across the palm and the fingers engage the lid. Normal action of the user's fingers causes the lid to be squeezed inwardly from the bottom to the top to efficiently expel the stored material.
