  • Patent number: 4867577
    Abstract: A gift package is adorned with an integral self-forming bow movable from a bow-unformed position to a bow-formed position by a pull-type or folding-type actuator to which the bow is operatively connected. The actuator may be integral with an article such as a shopping bag to be decorated, or the actuator and the bow may be formed as a discrete assembly which is separately attached to the article, or the bow may be integral with the article.

  • Patent number: 4832194
    Abstract: A flat toothpick dispenser supports toothpicks in a common plane with a carrier. Each toothpick is supported by webs integral with the carrier. A border surrounds the toothpicks and prevents pointed end portions thereof from becoming exposed during use. Spacer portions integral with the carrier enable toothpicks to be detached one at a time.

  • Patent number: 4822648
    Abstract: A decorative pull bow has multiple loops formed from a pair of bow members having bow sections which are slit to form multiple loop-forming elements. The bow members and a drawstring are shorter in length than heretofore without sacrificing the number of loops in the formed bow. The drawstring has a short pull stroke. The loops are automatically angularly arranged about a central longitudinal axis.

  • Patent number: 4755796
    Abstract: A manual data entry keyboard includes a plurality of key assemblies, each having an elongated arm and a touch contact at an outer end region of a respective arm. The arms are movable between a retracted position and an extended position, in the latter of which the touch contacts are spaced apart from each other by distances sufficient to enable a user to engage one touch contact at a time without simultaneously engaging an adjacent touch contact. A synchronizer ring simultaneously moves all of the arms between the retracted and extended positions.

  • Patent number: 4712267
    Abstract: A flexible brush block is moved along a shape-retaining S-shaped handle whose curved end regions of opposite curvature are responsible for bending the flexible block and bristles that are supported thereon into either a generally concave or a convex configuration.

  • Patent number: 4656064
    Abstract: A bow-forming ribbon assembly has a decorative flexible ribbon and a drawstring connected loosely to, and freely guided through pairs of apertures formed in, the ribbon lengthwise thereof. Between each pair of apertures, a bending zone is provided which extends at an angle of inclination, which angle is different and of opposite slope from that of the adjacent preceding inclination angle. During forming of the bow, the drawstring bends the ribbon across each bending zone, and forms bow loops distributed at various angles around the axis of the bow to form a pompon-like shape.

  • Patent number: 4515837
    Abstract: A bow-forming ribbon has a decorative flexible ribbon member and a drawstring connected loosely to the ribbon at points along its length by relatively stiff retainer members. Each retainer member extends generally transversely across the ribbon member, and each is inclined with respect to the transverse direction at an angle. Each retainer member is inclined at an angle different from that of the preceding retainer member. On forming the ribbon into a bow by pulling the drawstring relative to the ribbon, the inclined retainer members tend to skew the adjacent loops or segments of the bow relative to one another, so that loops distributed at various angles around the axis of the bow are formed, thus avoiding the tendency for the successive loops to seat themselves on one another in a fan shape.
