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.

Abstract: The present invention provides a filled package which exhibits a substantially colorless transparent appearance. The package is made of a substantially transparent container which exhibits the tint of a first color. A substantially transparent liquid which exhibits the tint of a second color which is different than the first color is housed in the container. The tint of the first color of the container and the tint of the second color of the liquid cooperate with one another such that the tinted container exhibits a substantially colorless transparent appearance when filled with the tinted liquid.

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.

Abstract: A case for cosmetics including a cover and a base. The cover and base have end and peripheral walls which together define an interior compartment. An integrally formed latching device is located in the front portion of the case. The latching device comprises a push tab in the form of a tongue-like section of the base peripheral wall. The distal and intermediate portions of the push tab are separated from adjacent portions of the base peripheral wall by at least one slot which extends alongside the push tab to its proximal end. Coacting cam means associated with the push tab and with an adjacent portion of the cover produces a force biasing the front portion of the base and cover apart when the push tab is moved inwardly with the latch engaged. Interengagement means is integrally formed on the cover and base peripheral walls to latch the cover to the base when the front portions of the base and cover are pressed together and unlatch when the front portions of the base and cover are forced apart.

Abstract: A bag-in-box composite container where the inner bag is easily separable from the outer box. In a preferred embodiment, a rigid one-piece outer box having a continuous side wall and a pair of end panels joined thereto defines a hollow box cavity. At least one of the end panels has a first aperture and at least two additional apertures therein. An inner bag is located within the hollow box cavity of the outer box. The inner plastic bag has a pouring spout with an annular flange connected thereto. The pouring spout extends through the first aperture in the end panel of the outer box. The annular flange of the pouring spout includes a pair of heat stakes which extend through the apertures in the end panel of the outer box. The heat stakes prevent relative rotation between the pouring spout and the outer box while temporarily securing the inner bag to the outer box. Upon emptying of the liquid contents, the inner bag is then separated from the outer box by depressing the pouring spout downward.

Abstract: Capillary channel structures having one or more intrastructure capillary channels, said structures comprising a polymer composition, wherein: said structures have a capillary channel base, and at least two polymeric capillary channel walls extending from said base along the length of said base in the axial direction for at least about 0.2 cm, said walls having a base end and a distal end, wherein said base and walls form said capillary channels; and said structures have a Specific Capillary Volume of at least about 1.2 cc/g, a Specific Capillary Surface Area of at least about 500 cm.sup.2 /g, and a Compressive Strength (Dry) of at least about 13,800 dynes/cm.sup.2. The structures can be in the form of fibers or sheets. The fibers have a Specific Capillary Volume of at least about 2.0 cc/g and a Specific Capillary Surface Area of at least about 2000 cm.sup.2 /g.

Abstract: A self-expanding flexible pouch that can be used as the measuring device for reconstituting a concentrated product contained therein. The pouch includes an improved one-piece extensible stay located in the throat area of the flexible pouch that is biased toward a relaxed, expanded, circular configuration but is initially held substantially flat in a stressed condition by the sealed top portion of the pouch. When the top portion of the pouch is removed, the improved stay expands to its relaxed, expanded configuration and thereby expands and opens the throat area of the pouch. The improved stay comprises a one-piece, continuous extensible loop having a pair of opposed hinges. The hinges are thinner in thickness than the remaining portions of the loop and aligned with the side peripheral edges of the pouch. Two opposed thick-walled sections are located between the opposed hinges. The opposed thick-walled sections provide the automatic opening force for the pouch.

Abstract: A sealed, self-expanding, reclosable, flexible pouch having a pair of extensible stays located in the throat area of the pouch. The extensible stays are biased toward a circular configuration but are initially held substantially flat in a stressed condition by the pouch's sealed top portion. When the pouch's top portion is removed, the extensible stays expand to their relaxed expanded configuration and thereby expand and open the throat area of the pouch. An inwardly oriented male securement means is attached to one extensible stay and extends along the throat area of the pouch. A complementary inwardly oriented female securement means is attached to the other of the opposing extensible stays and extends along the throat area of pouch. The complementary male and female securement means permits the throat area of the pouch to be sufficiently closed after initial opening, thereby constraining the pouch's contents.
