A dispenser includes a housing defining an internal volume. A cartridge is coupled with the housing. A tube extends into the internal volume of the housing. A first liquid is drawn from the internal volume into the tube through a first inlet in the tube when the pump assembly is actuated. A connecting member is positioned in the internal volume of the housing and coupled to the cartridge and the tube. A second liquid is drawn from the cartridge, through the connecting member, and into the tube through a second inlet in the tube when the pump assembly is actuated.

A fresh-keeping vacuum bottle with two compartments for preserving freshness, specifically designed to tackle the technical challenges faced by existing similar products in packaging powder products like freeze-dried powder, for example, prone to moisture, and challenged to reuse and assemble as replacement bottles. The bottle mouth of the vacuum bottle body and the large circle are connected through snap fitting to create a lower liquid storage compartment. The large circle includes a fixed large circle, a rotating large circle, and an inner sleeve large circle, with the fixed large circle being connected through snap fitting to the mouth fixed on the bottle body. The rotating large circle rotates the sealing plug until the upper thru-hole of the rotating large circle, the middle thru-hole of the sealing plug, and the lower thru-hole of the fixed large circle are aligned sequentially to achieve dual-compartment mixing.

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.

A fluid dispensing system including a fluid dispenser that is operable in a stand-alone mode, and a housing that is configured to removably receive the fluid dispenser for operation of the fluid dispenser in a housed mode. When the fluid dispenser is placed on top of a horizontal support surface for operation of the fluid dispenser in the stand-alone mode, a pump mechanism of the fluid dispenser is manually activatable to dispense an allotment of fluid by manually depressing an activation member of the pump mechanism. When the fluid dispenser is received by the housing for operation of the fluid dispenser in the housed mode, the pump mechanism is activatable by activating an actuation mechanism of the housing.

A dispenser includes a housing, a cartridge, and a pump assembly. The housing has a first liquid disposed therein, and the cartridge has a second liquid disposed therein. The pump assembly includes a tube. The first liquid is drawn from the housing into the tube through a first inlet in the tube when the pump assembly is actuated, and the second liquid is drawn from the cartridge into the tube through a second inlet in the tube when the pump assembly is actuated. The first and second liquids are combined within the tube to form a mixture.

A sprayer system includes a trigger sprayer having a trigger, a pump mechanism, and a nozzle. The sprayer system further includes a solvent reservoir for accommodating a solvent substance and a bottle for accommodating a concentrate substance. Further, the solvent reservoir is positioned above the trigger sprayer and is in fluid communication with the trigger sprayer and the bottle is positioned below the trigger sprayer and is in fluid communication with the trigger sprayer.

A dispenser includes a housing, a cartridge, and a pump assembly. The housing defines an internal volume. The cartridge is coupled with the housing. The pump assembly includes a tube that extends through the cartridge and into the internal volume of the housing. The tube includes a first inlet through which a first liquid is drawn into the tube from the internal volume when the pump assembly is actuated, and a second inlet through which a second liquid is drawn into the tube from the cartridge when the pump assembly is actuated.

The invention relates to a dispensing module for two liquid products, comprising: a first chamber (20) having a first wall, said first chamber having a first opening; a first piston (61) which can be displaced while resting on the wall of the first chamber; a second piston (64) which can be displaced while resting on a wall of the second chamber, and coupling means (62) for coupling both pistons while the product is being dispensed are provided. According to the invention, in order to prevent functional dysfunctions in the event of a distortion of the shape of container and to freely select the shape of the container, said dispensing module comprises a second chamber, the wall of which can be displaced while resting on the second piston, said second chamber comprising a second opening. This is achieved by virtue of the fact that the distortion of the container no longer leads to functional dysfunctions of the dispensing module. Also, the outer shape of the container can be freely selected.

A two-channel dispensing device intended to close a vial includes two reservoirs (13, 14), two channels having an inlet end opening into one of the reservoirs and outlet end opening outside of the reservoir. First closing means are provided in each channel, which can change from a closed position to an opened position in which a product can exit said reservoir. The two channels are isolated from each other at least between their inlet ends and the respective closing means. The reservoirs are formed by a single flexible pouch separated by a central partition (12) into first and second compartments (13, 14) performing the functions of the first and second reservoirs. The inlet end of the first channel opens into the first compartment (13) and the inlet end of the second channel opens into the second compartment (14), so that a single pouch makes it possible to form two reservoirs.
