Abstract: A fine applicator tip for a craft paint applicator for use in creating stylized textured designs. In a preferred embodiment, the applicator tip includes a parabolically-shaped inner passage to deliver the craft paint in a laminar flow with minimal flow resistance. This permits easy flow of the craft paint from the applicator with minimum hand fatigue. The size of the outside diameter of the surface of the dispensing end is critical for fine point application and for the craft paint flow to be uniform without adhering to the end surface of the dispensing end of the applicator tip. The thin sidewall thickness allows the dispensing end to be formed with a fine-tip and still have adequate rigidity. The applicator tip is formed with a reverse-threaded portion to affix the applicator tip onto an applictator. This allows the applicator to be easily removable for cleaning or replacement while prevents the applicator tip from being inadvertently removed.

Abstract: A vessel having a bottom with a vertical center-line and an annular side wall extending upward from the bottom of the vessel terminating into a rim portion. The vessel is further provided with at least one pouring spout formed in the side wall and extends peripherally about the side wall for at least a 75 degree arc with respect to the vertical centerline of the bottom. The pouring spout consists of two opposing concave upper pouring spout surfaces which converge upon and join a concave lower throat surface. The pouring spout thus provides a cross-sectional flow pattern initially in the shape of a convex-sided V that reforms into a round non-turbulent stream regardless of the flow rate of the liquid being poured. A complementary closure having at least one array of openings, for venting steam and/or straining liquids being prepared in the vessel is also disclosed.

Abstract: A syringe apparatus is disclosed for delivering a light-cured tooth composite material of a type that is essentially solid, yet pliable. The syringe apparatus comprises a barrel and a plunger which is used to push the composite material through the barrel. The barrel has an outlet end with a divider formed as an integral part thereof. The divider cuts, sectionalizes, and individually compartmentalizes the material as it is pushed to the outlet of the barrel. Thus, the material is extruded into a plurality of individualized sections. Each individualized section of material is contained in a separate compartment having a support surface that optionally extends beyond the outlet end of the barrel. The support surface serves as a cutting plate against which a dental tool can pinch off a discreet portion of the material.

Abstract: An applicator tip structure and method for applying a flexible sealant material on and around the heads of fasteners and on and around the surface surrounding the fastener head to prevent fluid passage between the fastener and the materials through which the fastener passes. The applicator tip has an outlet opening that is greater than the diameter of the sealant passageway in the applicator tip and that also is greater than the largest transverse dimension of the fastener, to provide an overlap area around the fastener head. In use the applicator tip is applied over the fastener head and is pressed into the surrounding surface around the fastener head to define an enclosure around the fastener head, into which enclosure the sealant material is injected to completely surround the fastener head and the adjacent surface to completely seal the fastener from fluid passage therearound.

Abstract: A non-resealable dispenser cap construction having an elongate tapered, stepped hollow spout member with an exterior shoulder intermediate its ends, and a discharge orifice. A closure cap member having a transverse closure wall is mounted on the spout member with the transverse wall engaging and closing over the discharge orifice.

Abstract: A method for the filling of a container with a potable liquid, such as fruit juice, and a filler nozzle for practicing the method. Prior methods for filling containers with potable liquids have often employed a series of nozzles, each discharging a single stream of liquid, falling under the action of gravity, vertically downward through an opening in a nozzle, each nozzle acting in cooperation and being attached to its valve. As the container is filled, both splashing and foaming of the liquid in the container, has often caused problems. According to the method and apparatus of this invention, the potable liquid to be dispensed into a container is directed to the interior surface of the container at a point above its intended fill level. By virtue of this method, foaming and splashing are minimized at each filler nozzle station.

Abstract: A portable dispensing appratus which includes a resiliently deformable dispensing reservoir adapted to mount removably on the uppermost end of a dip tube which extends into a bulk container of liquid. The dip tube includes a one-way inlet valve near its lowermost end which prevents flow of liquid out of the dip tube, but which permits flow into the dip tube. Suction created by compressing the resiliently deformable reservoir causes liquid to enter the dip tube through the one-way inlet valve and to flow into the reservoir. The dispensing reservoir can then be removed from the dip tube and taken to a location where it is desired to dispense all or a portion of the liquid. The liquid is dispensed by squeezing the resiliently deformable reservoir, thereby forcing the liquid out through the nozzle. A one-way, pressure-operated outlet valve is preferably located in the dip tube inside the bulk container to permit compression of the resiliently deformable reservoir after placement of the reservoir on the dip tube.
