A connection system between a head and a bottle of a trigger dispensing device includes a main skirt having a first flexible tab and a neck having a first sloping plane and a first pocket. The first flexible tab extends circumferentially from a first end to a second end, and the first end is joined to an annular wall by a closing wall. The system also provides for an auxiliary window obtained through the annular wall of the main skirt, and a rigid auxiliary tooth of the neck, suitable to snap into the auxiliary window.

A connection system between a trigger dispensing head and a bottle of a dispensing device is provided. The neck of the bottle and the skirt of the trigger dispensing head are engageable with each other exclusively in a relevant predefined angular position, wherein the axial snap-engagement between the skirt and the neck is allowed.

The invention relates to a liquid dispensing system comprising a liquid dispensing device (2) and one or more containers (3) for storing the liquid to be dispensed, wherein the liquid dispensing device is releasably connected to one of the containers. The liquid dispensing system includes means for preventing refilling of the at least one container. The refill prevention means may include a restriction element (7) which may be fixed in a neck of the container and may almost completely close off a fill opening defined by the neck. The invention further relates to a method of dispensing a liquid, comprising the steps of filling at least one container with the liquid to be dispensed, providing a liquid dispensing device, connecting the liquid dispensing device to the at least one container, and actuating the liquid dispensing device, wherein after filling the container is provided with means for preventing refilling thereof.

A dispensing unit for dispensing a fluid product includes a reservoir for packaging the product, that has a body surmounted by a neck defining an upper opening, a system for dispensing the product, and a device for fixing the dispensing system to the reservoir. The fixing device consists of one single part having securing means on the neck of the reservoir actuated by an axial translational movement and disconnection means with respect to the neck of the reservoir actuated by a rotational movement.

According to some illustrative embodiments, an angularly adjustable spray nozzle is employed that includes: a base section having a water flow path extending lengthwise there-through; a head section aligned at an end of the base section and rotatably mounted to the base section; wherein a flow path through the base section is inclined at an angle to a flow path through the head section such that when the head section is rotated a predetermined extent relative to the base section, the spray device is moved between a substantially straight configuration of the head section with respect to the base section and an angular configuration of the head section with respect to the base section; wherein the head section includes a rotatable turret assembly having a plurality of selectable spray type discharge ports and a sleeve to which the rotatable turret assembly is mounted, the rotatable turret assembly including labels on a periphery thereof corresponding to respective ones of the selectable spray type discharge ports, and the sleeve having a plurality of windows through which the labels are viewed when aligned; and wherein the spray device is configured such that when the spray device is oriented in a generally horizontal use position a respective one of the labels corresponding to a selected spray type is displayed within a respective one of the windows that is located at a top side of the sleeve whether the spray device is in the substantially straight configuration or in the angular configuration.

A foam spray can includes a motor pump, a foaming tube, a can body, a cover body and a quick release structure. One end of the foaming tube is connected to the motor pump. The can body contains liquid. The cover covers an opening of the can body. The quick release structure includes a first and a second engaging structures disposed on the cover body and the can body, respectively. The first engaging structure can be engaged with the second engaging structure along a first direction. The first engaging structure can be separated from the second engaging structure in a moving distance less than a half circumference of the opening of the can body along a second direction opposite to the first direction. Therefore, the cover body and the cover body of the foam spray can be quickly assembled and disassembled.

A gas-filled resilient body and uses thereof are described. The gas-filled resilient body may be used as a valve member, as a spring or as a gas-propelled dispenser.

The present invention provides an improved pump assembly incorporating a liquid pump and an air pump and which pump includes a flexible annular diaphragm member coaxially about a piston-forming element forming a component with the liquid pump.
