A dispensing device that attaches to a container has: (a) a hollow tube with opposing entrance and exit ends with a connector on the entrance end and a wall defining a flow channel; (b) a sleeve with opposing entrance and exit ends slidably extending over the hollow tube; (c) a sealing gasket between and contacting the hollow tube and sleeve; (d) a trigger mount rigidly attached to the hollow tube or container; (e) a trigger hingedly connected to the trigger mount and operatively connected to the sleeve; (f) an elastic element between the trigger and the hollow tube and/or container; wherein the exit end is closed and there is an opening through the hollow tube wall proximate to the exit end; the sleeve has an open dispensing end, reduces in inside diameter at dispensing end and engages the hollow tube when closed and disengages from the hollow tube when open.

Bag-on-valve (BOV) systems adapted to dispense viscous liquids, particularly syrup, which ordinarily crystallize in the presence of atmospheric oxygen and thereby block the flow path from the bag to the exterior of the container. The present systems utilize a BM flow path diameter effective to inhibit crystallization-based blockage. This facilitates storage of syrups art room temperature without needing refrigeration, and allows control over the dispensing amount through the use of a spray actuator. Methods for filling a BOV system with viscous product include a step to remove remnant product in the valve stem which may inhibit initial discharge. Such methods include exposure to a water source to dislodge and remove or dilute the remnant for evaporation or expulsion during initial discharge.

A shoulder cover for an aerosol container that can be readily positioned and attached to the aerosol container having two stems. The shoulder cover is attached to a mounting cup that includes an upper tier part having two stems protruding from a top wall thereof and having long sides and short sides, and a cylindrical part. The shoulder cover includes an outer circumferential wall, a roof wall, a cylindrical wall extending downward from the roof wall, and locking structure provided to the cylindrical wall and retaining the shoulder cover by engaging with the cylindrical part of the mounting cup, and positioning structure for fitting with the upper tier part to thereby position a mating position of the shoulder cover is formed.

A dispensing device that attaches to a container has: (a) a hollow tube with opposing entrance and exit ends with a connector on the entrance end and a wall defining a flow channel; (b) a sleeve with opposing entrance and exit ends slidably extending over the hollow tube; (c) a sealing gasket between and contacting the hollow tube and sleeve; (d) a trigger mount rigidly attached to the hollow tube or container; (e) a trigger hingedly connected to the trigger mount and operatively connected to the sleeve; (f) an elastic element between the trigger and the hollow tube and/or container; wherein the exit end is closed and there is an opening through the hollow tube wall proximate to the exit end; the sleeve has an open dispensing end, reduces in inside diameter at dispensing end and engages the hollow tube when closed and disengages from the hollow tube when open.

A dispensing device for attaching to a container having a valve stem includes: (a) a hollow tube having a flow channel defined by a wall extending between entrance and exit ends with a connector on the entrance end for connecting to the valve stem; (b) a sleeve extending slidably over a portion of the hollow tube, the sleeve extending over, and having an opening proximate to, the hollow tube's exit end; (c) a sealing gasket around the outside of the hollow tube and between the hollow tube and the sleeve that prevents fluid communication past the gasket between the hollow tube and sleeve; (d) a trigger mount rigidly attached to the hollow tube or container; (e) a trigger hingedly connected at a first location to the trigger mount and operatively engaged with the sleeve at a second location; and (f) an elastic element between the trigger and the hollow tube and/or container.

A multi-chambered bottle includes first and second chambers, a metering stage, a pour spout and a cap. The metering stage includes first and second metering stage sections connectable to respective mouths of the first and second chambers. Each metering stage section comprises a nozzle having a liquid inlet orifice and a liquid outlet orifice, and a vent tube having an air inlet orifice and an air outlet orifice at opposite ends of the vent tube, the air inlet orifice to be disposed outside of the respective chamber and the air outlet orifice to be disposed inside of the respective chamber, the vent tube disposed relative to the nozzle such that a line crossing a center of the air inlet orifice and a center of the liquid outlet orifice forms an acute angle with a normal axis of the bottle.

A dispensing device having two output channels (6) for selectively dispensing a preferably liquid product is proposed. In order to switch between the output channels (6), the dispensing device has a switching part (10) that can be rotated by means of an associated actuation part (9). A simple and cost-effective design is made possible by the fact that the actuation part (9) engages axially into the switching part (10), and the switching part (10) has a peripheral seal and is self-sealing.

Provided is a nozzle cap for aerosol container that can be used for cleaning a nozzle of an aerosol container that has a plurality of stems, and preventing the nozzle from being pushed down. The nozzle cap includes a plurality of bar-like pieces 11 that can be inserted from ejection ports 24 of a nozzle 20 into ejection-side communication passages 23a at least until distal ends 11a reach upper ends 22d of stem-like communication passages 22a, and a lower protrusion 14 that prevents the nozzle from being pushed down by abutting on a cover member 30 below ejection tubes 23 of the nozzle 20 when the bar-like pieces 11 are inserted into the ejection-side communication passages 23a.

A dispensing device as well as a dispensing head and use thereof are proposed. Through depression of the dispensing head, an associated dispensing valve is opened and the product to be delivered can escape or be dispensed through an outlet space and via a downstream outlet valve. In order to prevent or at least minimize subsequent dripping or foaming, the volume of the outlet space is initially reduced upon actuation of the dispensing head and enlarged again upon completion of actuation, particularly after closing of the dispensing valve, whereby the product is suctioned away from the outlet or outlet valve back into the outlet space.

A multi-chambered bottle includes first and second chambers, a metering stage, a pour spout and a cap. The metering stage includes first and second metering stage sections connectable to respective mouths of the first and second chambers. Each metering stage section comprises a nozzle having a liquid inlet orifice and a liquid outlet orifice, and a vent tube having an air inlet orifice and an air outlet orifice at opposite ends of the vent tube, the air inlet orifice to be disposed outside of the respective chamber and the air outlet orifice to be disposed inside of the respective chamber, the vent tube disposed relative to the nozzle such that a line crossing a center of the air inlet orifice and a center of the liquid outlet orifice forms an acute angle with a normal axis of the bottle.
