Dual reservoir spray dispenser
A dual reservoir spray dispenser can separately hold two different components, while jointly dispensing the two different components as a sprayable composition. A common actuator of the dual reservoir spray dispenser can include a pipe ( 2 ) having a sinuous path. The pipe can include two inlet orifices ( 3, 5 ) and an outlet orifice ( 4 ).
1. A spray dispenser system for mixing a first component and a second component into a sprayable composition, the spray dispenser system comprising:
a first reservoir configured to hold the first component;
a first pump unit in fluid communication with the first reservoir;
a second reservoir configured to hold the second component, the second component being different from the first component;
a second pump unit in fluid communication with the second reservoir;
a nozzle tip configured to spray the sprayable composition; and
a common spray actuator operatively associated with the first pump unit and the second pump unit,
the common spray actuator comprising a pipe having a sinuous path,
a first end of the pipe having a first inlet orifice in fluid communication with the first pump unit,
a second end of the pipe, opposite the first end, having one outlet orifice in fluid communication with the nozzle tip,
the pipe having a second inlet orifice located between the first inlet orifice and the outlet orifice and in fluid communication with the second pump unit,
the first inlet orifice and the second inlet orifice defining an inlet axis,
the outlet orifice and the nozzle tip defining a spray direction axis,
the spray direction axis being perpendicular to the inlet axis, the pipe comprising a first section between the first inlet orifice and the second inlet orifice, the first section has a semi-circular shape, the pipe further comprising a second section between the second inlet orifice and the outlet orifice, and the second section has a “s” shape.
2. The spray dispenser system of claim 1 , further comprising a container having a separation wall that delimits two different compartments to form respectively the first reservoir and the second reservoir.
3. The spray dispenser system of claim 1 , wherein the common spray actuator comprises a body and a skirt circumferentially extending downwards.
4. The spray dispenser system of claim 1 , further comprising the first component and the second component, wherein:
the first component is held in the first reservoir and the second component is held in the second reservoir;
the first component and the second component are different from each other; and
upon actuation of the common spray actuator, the first component and the second component are homogeneously mixed and dispensed as the sprayable composition.
5. The spray dispenser system of claim 4 , wherein the first component and the second component are skin care components, hair care components, personal care components, grooming components, oral care components, health care components, fabric care components, or home care components.
6. The spray dispenser system according to of claim 4 , wherein the first component and the second component are in a liquid form at standard conditions.
7. The spray dispenser system of claim 4 , wherein the first component and the second component differ from each other by at least one of a presence of at least one material, a proportion of at least one material, at least one physicochemical property, or a visual appearance.
8. The spray dispenser system of claim 4 , wherein one of the first component or the second component comprises at least one of a material being inherently instable under determined conditions, a material being incompatible with another material comprised in the other of the first component or the second component, a material being degraded by another material comprised in the other of the first component or the second component, or a compound chemically reacting with another material comprised in the other of the first component or the second component.
9. The spray dispenser system of claim 4 , wherein the first component comprises a volatile solvent or a non-volatile solvent.
10. The spray dispenser system of claim 4 , wherein:
the second component comprises fragrances, microcapsules, and a suitable carrier; and
at least part of the fragrances are encapsulated in the microcapsules.
11. The spray dispenser system of claim 1 , wherein:
the first reservoir is configured to be removably coupled with the first pump unit; and
the second reservoir is configured to be removably coupled with the second pump unit.
12. A method, comprising
providing the spray dispenser system, according to of claim 4 ,
actuating the common spray actuator for pumping and thereby homogeneously mixing given portions of the first component and the second component for obtaining the sprayable composition; and
spraying the sprayable composition.
13. The spray dispenser system of claim 4 , wherein the first component comprises a volatile agent, the volatile agent including at least one of ethanol, methanol, propanol, isopropanol, or butanol.
14. The spray dispenser system of claim 10 , wherein the second component further comprises at least one additional agent, the at least one additional agent being a suspending agent, a colouring agent, an antioxidant, an ultraviolet inhibitor, a cyclodextrin, a quencher, or skin care actives.
