  • Patent number: 5242644
    Abstract: A process and extrusion die for making capillary channel structures having one or more intrastructure capillary channels. The process includes feeding a flowable, molten polymer composition through an extrusion die having an annular base orifice from which a plurality of capillary channel wall orifices radially extend. The extrusion die has a gas inlet port located interior to the annular base orifice. Simultaneous with feeding the polymer composition through the extrusion die's annular base and capillary channel wall orifices a gaseous stream is directed through the gas inlet port in the same direction as the flow of molten polymer composition. Subsequent to exit of the polymer composition from the extrusion die, the capillary channel structure is drawn to a desired size and cooled.

  • Patent number: 5215221
    Abstract: A disposable unit dose dispenser is provided for fluidizing and dispensing a predetermined quantity of powdered product, such as an antihistamine or a decongestant. The dispenser includes a first layer and a second layer connected together to form a gas chamber and a product reservoir adjacent one another. The product reservoir includes a delivery tube adapted to dispense the powdered product. The dispenser also includes a seal which separates the gas chamber from the product reservoir such that when pressure is applied to the gas chamber by squeezing the dispenser the seal ruptures causing a jet of gas to discharge from the gas chamber into the adjacent product reservoir fluidizing and dispensing substantially all of the powdered product from the product reservoir through the delivery tube.

  • Patent number: 5209376
    Abstract: A finger actuated dispenser for a multi-component reactant toothpaste, or other fluent materials. The dispenser preferably comprises at least two coaxial cylindrical product reservoirs wherein the uppermost end of each product reservoir communicates with the other reservoirs through generally coaxial nozzles. The lowermost end of each reservoir is equipped with a concentric piston connected rearward of its leading face to the rearward portions of the other pistons by a plurality of radially oriented spokes having knife edges on their forwardmost surfaces. The knife edges taper outwardly at an acute angle relative to the longitudinal axis of the reservoirs from the interior of the innermost reservoir toward the outermost reservoir, thereby outwardly expanding the innermost surface of the innermost reservoir wall as the pistons and knife edges are advanced upwardly relative to the product reservoirs.

  • Patent number: 5186344
    Abstract: A package having means for producing an audible signal, such as a "click", which signals the consumer as soon as a predetermined level of engagement between a container and a closure has been achieved. Normally the desired level of engagement establishes some type of seal between the package components which contact one another. In a particularly preferred embodiment, a semi-rigid polymeric container having a discharge orifice, a sealing member preferably comprising a filter support member secured across the discharge orifice of the container and a closure having attachment means capable of forming a substantially gas-tight atmospheric seal between all three components upon initial closing of the package to the atmosphere is provided. The container and closure are further provided with interfering projections, at least one of which is resiliently deformable, which will contact one another only after the sealing member has been removed from the package and discarded and the closure reapplied to the container.

  • Patent number: 5167897
    Abstract: An improved method and apparatus for incrementally stretching "zero strain" stretch laminate webs to impart elasticity thereto in the direction of initial stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate material is formed of at least two plies of material which are either intermittently or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies is stretchable and elastomeric, while the second ply is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration.

  • Patent number: 5165761
    Abstract: A method of making toothbrushes having bristle tufts with ends in two or more distinct planes, all of said bristle tufts having individual bristles which are substantially uniformly rounded at their free ends. The method of making is a repeated sequence of steps used to attach all of the bristle tufts of the shortest overall length followed by cutting and end rounding of the individual bristles in the first group of tufts while all of the free ends of the bristles are in a first plane. This is done prior to affixing the next group of bristle tufts of greater overall length. The cutting and end rounding sequence is thereafter repeated for each ascending bristle tuft elevation. The final toothbrush bristle contour is a function of the pattern of attachment for each bristle tuft elevation.
