A multi-modal olfactometer including a carrier assembly slidably coupled with a track and movable between a loading and testing position, a distribution block coupled with the carrier assembly and including a plurality of independent flow channels, a plurality of bottles configured for containing a gas stimuli and for being coupled with the distribution block, a plurality of tubes in flow communication with corresponding channels defined in the distribution block, an outlet piece including a plurality of independent flow channels that are each in flow communication with one of the respective tubes, and at least one actuator positioned adjacent to the bottles when the carrier assembly is in the testing position. The actuator operates to impact each of the bottles to cause the respective gas stimulus to flow through the respective channel in the distribution block, tube, and channel in the outlet piece for inhalation by a test subject.

Described herein is a fluid dispensing device that enables rapid fluid mixing of separate solutions prior to dispensing. Also described herein are methods of using and manufacturing the fluid dispensing device. The fluid dispensing device is useful with a variety of reactive and/or concentrated formulations, including cleaning formulations.

The present invention relates to a foundation container including a discharge pump having a short working stroke, the foundation container including an outer container main body (10); an outer container cap (20) coupled to the outer container main body (10) and opened/closed; a container main body (30) coupled inside the outer container main body (10); and a container cap (40) coupled to the upper portion of the container main body (30) and opened/closed, wherein the foundation container comprises a container interruption plate (34) coupled inside the upper portion of the container main body (30), a discharge pump (50) coupled to the center of the container interruption plate (34), and a content diffusion plate (60) coupled to the discharge pump (50); the discharge pump (50) comprises a pump main body (52), a pump upper body (54), a pump inner body (56), a discharge valve (57), and an elastic member (58); and the diffusion plate (60) is configured to extend to the pump upper body (54).

A dispenser assembly for dispensing a liquid product includes a bottle configured to store the product, a venting pump connected to the bottle and configured to control dispensing of the product from the bottle, a mounting component, and an enclosure connected to the mounting component and engaging the bottle, wherein the enclosure is movable relative to the mounting component between an open configuration and a closed configuration, and wherein the bottle is selectively removable from the enclosure when the enclosure is in the open configuration.

A dispenser main body (11) includes a cylindrical-shaped fitted portion (16a), and a nozzle (40) includes: a nozzle main body (41) and a nozzle extension body (42). The nozzle (40) is provided with a dispensing tube (51) including: a first dispensing tubular portion (51a) and a cylindrical-shaped second dispensing tubular portion (51b). A cut-out (52a) is provided in the front end of the first dispensing tubular portion (51a) or in a base end of the second dispensing tubular portion (51b), and an opening end of the cut-out (52a) is closed by the first dispensing tubular portion (51a) or the second dispensing tubular portion (51b) to provide an air inlet hole (52) in the dispensing tube (51).

The present invention relates to a press-type liquid pump. The liquid pump comprises a fixed unit fixed relative to a container and a movable unit capable of performing a reciprocating motion relative to the fixed unit, and a liquid product is pumped to the exterior of the container. The reciprocating motion is achieved by a pressing force applied by a user to the movable unit to move the movable unit relative to the fixed unit in combination with an elastic restoring means for restoring the movable unit relative to the fixed unit after the pressing force is removed. The elastic restoring means is a plastic elastic compressing means located below a toothed sleeve and installed between the fixed unit and the movable unit, which comprises at least one elastic strip generally formed in an arc shape.
