  • Patent number: 5633026
    Abstract: A conformable, self-aligning, high extraction efficiency tea filter pack capable of flavor extraction efficiencies comparable to those obtained using an identical quantity of bulk tea leaves and a paper filter under identical brewing conditions, but which exhibits substantially consistent pot-to-pot brew strength for any given automatic drip coffee maker. The preferred filter pack is formed from two layers of flexible material which are secured to one another about their outermost periphery with a predetermined quantity of tea leaves housed within a brew chamber formed between the two layers. The brew chamber exhibits a maximum volume between about 100 percent and about 400 percent greater than the volume of the dry tea leaves contained therein. The discharge flow rate from the brew chamber is slower than the inlet flow rate into the brew chamber to permit a buildup of water and flooding of the brew chamber.

  • Patent number: 5613609
    Abstract: A dual chamber-child-resistant blister package is provided. The blisters of the package include a storage chamber and a discharge chamber. In addition, the blister includes restraint means for preventing the medicament from moving from the storage chamber to the discharge chamber until a predetermined force is applied to the blister package. The medicament may not be dispensed directly from the storage chamber, since a nonrupturable layer is located adjacent the storage chamber of the blister. The nonrupturable layer includes an opening, or a mechanism such as a score line for forming and opening) through which the medicament can pass adjacent the discharge chamber. A rupturable layer is also provided to seal the medicament within the blister. Typically, the rupturable layer is located adjacent the nonrupturable layer to seal the opening in the nonrupturable layer. The blister package may also include indicia associated with the blisters to help insure compliance with complex therapeutic regimens.

  • Patent number: 5560544
    Abstract: The present invention provides an improved atomization system for dispensing and atomizing a fluid product having film-forming characteristics. The atomization system includes a nozzle for atomizing the fluid product which has been formed of a reduced wettability composition including a base material and a wettability-reducing component for reducing the wettability of the base material with the fluid product. The reduced-wettability attribute ensures that the product will tend to "bead up" on the surfaces of the nozzle assembly rather than wetting or coating the surfaces. The surfaces will thus tend to repel the product, once the supply pressure driving the fluid toward the nozzle is relieved, leaving the critical nozzle surfaces substantially free of a film of product which would tend to dry and form a residue on the critical nozzle surfaces when exposed to atmospheric air.

  • Patent number: 5529224
    Abstract: A self-closing liquid dispensing package comprises a liquid container and a self-closing flat channel valve. The channel valve has an inlet adjacent to and in liquid communication with the liquid container. It also has a mouth, a first sheet member, and a second sheet member wherein the first and second sheet members have an original planar position and longitudinal edges, are indexed face-to-face, and are sealed together along longitudinal edges and wherein the first and second sheet members are sufficiently flexible to arch away from each other to form a flow channel therebetween to permit a flow of contained liquid in response to external pressure applied to the liquid container. At least one of the sheet members is sufficiently resilient to return the first and second sheet members to the original planar position when the external pressure is released.

  • Patent number: 5518147
    Abstract: A collapsible pump chamber, e.g., a bellows, for use with a liquid dispensing pump device is provided. The collapsible pump chamber includes a collapsing side wall which defines an internal volumetric portion of the pump chamber. The collapsing side wall has a structure which collapses in a predetermined pattern as the pump device is actuated. For example, the predetermined pattern of collapse could result in an initially relatively small volumetric change in internal volume per given stroke length followed by an increased volumetric change in internal volume per given stroke length. Thus, the pump device would initially provide very good control over the amount of product is dispensed; giving precise control during a partial actuation. However, the same pump device would also be capable of delivering a large volume of product during a complete actuation.

  • Patent number: 5517737
    Abstract: In accordance with the present invention there is provided an apparatus for conveying a web. The apparatus is able to continuously stretch the web or continuously release the stretching forces from a web in the cross-machine direction. The apparatus includes two pairs of opposing belts wherein each belt travels along an endless path. The pairs of belts diverge or converge from each other in the cross-machine direction. Each pair of belts comprises an upper belt and a lower belt which are adjacent to each other. Each of the upper and lower belts has a non-planar outer surface which contacts the web. The non-planar outer surfaces of each upper belt continuously abuts the non-planar outer surface of its adjacent lower belt along a predetermined distance when traveling in the machine direction. This creates at least one nip for continuously gripping the web while it is being conveyed. The apparatus also includes a means for driving the belts so as to convey the web in the machine direction.

  • Patent number: 5511680
    Abstract: The present invention pertains to improved closure arrangements which are durable in construction, yet easy to open and reclose, and which provide an initial hermetic seal with tamper evidency, all utilizing a one-piece lid design. In two embodiments according to the present invention, unique combinations of a mechanical interlocking closure system, heat-sealing or bonding, and a weakened failure zone are employed in the vicinity of the lid/container juncture to achieve these desirable characteristics. In a third embodiment of the present invention, a mechanical interlocking and sealing arrangement is utilized to achieve hermetic sealing of the container without the need for a heat seal or bonded region, and a weakened failure zone is located just inward of the mechanical interlocking connection.

  • Patent number: 5511275
    Abstract: A toothbrush is provided for achieving improved interproximal cleaning without increasing gum irritation. The bristles of the toothbrush have a generally "V" shaped side profile. In addition, the exposed ends of all of the bristles are properly end rounded. The dimensions and shape of the "V" shape fall within a certain range, as does the stiffness of the bristles. These characteristics allow the bristles to penetrate into the interproximal areas with enough force to effectively clean these areas without causing irritation to the user's gums.
