Disclosed is a liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900), including a movable unit and a fixed unit. The movable unit is capable of moving relative to the fixed unit so as to pump a product out. An elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is provided between the movable unit and the fixed unit, and the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) comprises at least one elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931). The elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) applies a biasing force to the movable unit to restore the movable unit after the product is pumped. The liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900) further comprises an elastic mechanism adjusting member movable between a first position in which the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a relaxed state, and a second position in which the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a preloaded state. With the provision of the elastic mechanism adjusting member, it is convenient to press down a pressing head (110, 210, 310, 410, 510, 610, 710, 910) during use, and the yielding deformation of the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) due to long-term stress can also be avoided.

Device for dispensing a fluid product comprising a body (1) having a dispensing opening (12) and a piercing element (4), said body (1) containing a reservoir (10) containing at least two doses of fluid product, said reservoir (10) having a proximal axial opening closed by a membrane (30) and a distal axial opening closed by a piston (20), mounted in a sliding manner in said reservoir (10) in order to dispense a dose of fluid product on each actuation, said reservoir (10) being axially movable with respect to said body (1) between a rest position, in which said piercing element (4) does not pass through said membrane (30), and a dispensing position, in which said piercing element (4) passes through said membrane (30), said membrane (30) being capable of reclosing in a sealed manner after each actuation, when said piercing element (4) comes back out from said reservoir (10), said device comprising a lateral actuation system having an actuating member (50), laterally movable with respect to said body (1) between a rest position and an actuating position, said actuating member (50) being resiliently biased towards the rest position thereof, said actuating member (50) comprising a first cam (51) cooperating with said reservoir (10) and a second cam (52) cooperating with said piston (20), such that the movement of said actuating member (50) to the actuating position thereof first moves said reservoir (10) to the dispensing position thereof then causes said piston (20) to slide in said reservoir (10), to dispense a dose of fluid product.

A spray device includes a first spray tip having a first fluid pathway defining a first flow area, and a second spray tip includes a second fluid pathway that defines a second flow area that is larger than the first flow area of the first spray tip. The first and second spray tips are side-by-side and spaced from one another at a distal end of the spray device. When a first fluid having a volumetric flow rate is introduced into the first spray tip and a second fluid having the same volumetric flow rate is introduced into the second spray tip, the first fluid will flow through the first fluid pathway at a greater velocity than the second fluid will flow through the second fluid pathway.

A viscous concentrate dispensing device includes a storage container tube configured to hold a viscous concentrate, a first cap configured to fit over a first end of the storage container tube, and a second cap configured to fit over a second end of the storage container tube. The first and second cap hold the storage container tube in place for storage and seal the viscous concentrate within the storage container tube. A plunger is configured to fit in the first cap and the second cap and hold the plunger in place for storage. A seal is disposed within the storage container tube for extruding the viscous concentrate when a force is applied with the plunger to depress the seal.

A handheld solids dispenser. The dispenser includes a housing defining an inlet passage and an outlet passage. A delivery mechanism is supported within the housing and is positioned between the inlet passage and the outlet passage. Actuation of the delivery mechanism causes the delivery mechanism to transport a desired amount of solids material from the inlet passage to the outlet passage. The delivery member may be in the form of a plunger slidably positioned within the housing. The delivery mechanism may be in the form of a screw conveyor driven by a drive motor.
