  • Publication number: 20150166210
    Abstract: A multiple-way matching or correlation process guides placement of a particular product at a target placement location. The process may include providing a product package that includes a non-textual placement guidance symbol externally visible on the product package and providing a product container that includes the non-textual placement guidance symbol externally visible on the product container. The process may include providing one or more labels adapted for placement at different locations proximate to the target placement location for the particular product. The labels may include the non-textual placement guidance symbol to visually guide stocking of the particular product to the target placement location. Correlation (e.g., through exact matching) between the non-textual placement guidance symbol on the packaging or container with the non-textual placement guidance symbols on the labels allows for efficient and accurate placement of the particular product at the target placement location.

  • Patent number: 6843430
    Abstract: A battery operated atomizer device comprising, in a housing (22), a liquid reservoir (30) from which a capillary type liquid delivery system (38) extends to contact a piezoelectric actuator an atomization plate assembly (34), the assembly (34) being supported by means of wire-like elements (36) in cantilever fashion over the liquid delivery system, the liquid delivery system comprising an outer tubular member (52) and a solid rod (56) which have facing surfaces configured to define between them, longitudinal capillary liquid passages.

  • Patent number: 6786427
    Abstract: A plug and wickholder is configured to be reliably sealed to the neck of a bottle which contains a liquid to be atomized and to a cap which seals the bottle during storage. The plug and wickholder includes a first generally tubular wall which contains a wick and which fits tightly into a cap sealing wall, and it further includes a generally cylindrical sealing wall which fits tightly into a bottle neck. A second generally vertical tubular wall is interposed between the first generally tubular wall and the generally cylindrical sealing wall.

  • Patent number: 6450419
    Abstract: A liquid atomizer is constructed with a hollow shell-like top cover and a unitary molded main support which snaps into place inside the top cover and divides it into upper and lower regions. The main support includes formations for mounting, on its upper side, a printed circuit board assembly including an electrical oscillator, as well as a piezoelectric actuator and orifice plate pump assembly. The main support also includes formations for removably mounting, on its lower side, a battery and a liquid reservoir. An openable bottom cover closes the bottom of the device and allows access to the battery and to the liquid reservoir for replacement of these elements.

  • Patent number: 6446880
    Abstract: There is described, in conjunction with a vibrating orifice plate type atomizing dispenser, a refill reservoir which has a wick mounted in a unitary wickholder to provide precise locating of the wick in relation to the vibrating orifice plate in the dispenser. There are also described a novel reservoir overcap and wickholder construction in which mating tubular surfaces on these elements telescope together to ensure a good liquid seal without interfering with the wick. There is also described a novel camming arrangement which enables the overcap to be removed easily from the reservoir.

  • Patent number: 6341732
    Abstract: Liquid to be atomized is supplied from a wick to the underside of a vibrating orifice plate which pumps the liquid up through atomizing orifices in the plate and ejects the liquid from is upper side; and liquid which is pumped up through the orifices in an elevated region of the plate, but which has not been ejected, is directed back down through larger openings in a lower region of the plate. The liquid also flows back onto the wick which places the liquid in capillary communication along the underside of the plate with the atomizing orifices for reputing and ejection.
