A method and apparatus for depositing a fluid over an interface. A nozzle may comprise a body having a first end and a second end, an input located at the first end of the body, an output located at the second end of the body, and a plurality of channels located within the body. The input may be configured to receive a fluid. The plurality of channels may have a configuration that causes the fluid received through the input to flow through the plurality of channels and exit the output to form a deposition having a desired shape over an interface.

The systems and processes described herein correspond to a device that is to be detachably coupled to a hydration system, such as a backpack-based hydration system. The device may receive fluid from a reservoir included within the hydration system via a reservoir hose coupled to the reservoir. The device may include a pump and one or more valves that control the extent to which the fluid flows in and out of the interior of the pump. The fluid may exit a mouthpiece of the device based at least partly in response to a user applying pressure to the exterior surface of the pump, such as by the user squeezing or otherwise compressing the pump. The user may consume or otherwise use the fluid without having to apply suction to the mouthpiece of the device.

A connecting structure for a liquid container includes a receiving groove. The liquid container having a suction tube is disposed in the receiving groove. A top end of the receiving groove is engaged with a connecting base. A front side of the connecting base is pivotally connected to a locking assembly protruding frontwards. A liftable base being movable along a top-bottom direction and a front-rear direction is disposed in an inner side of the connecting base, and has a bottom frame engaging with a sleeve that is for being connected to and communicating with a liquid pipeline and fits around the suction tube. Two extending arms extending frontwards out of the bottom frame are pivotally connected to the locking assembly. A left side and a right side of the bottom frame are pivotally connected to two swinging arms that extend backwards and are pivotally connected to the connecting base.

A mobile spray device that is wearable on the back of a user that incorporates a fill hose of diameter and a spray hose of diameter, the hoses being connected to a pump housed in a top front compartment of said device which is connected to a battery and controller housed in a bottom front compartment of said device, both top and bottom compartments having hard outer shells, and wherein these compartments have apertures that allow for connection of wires from the battery and controller and hoses to pass through an intermediate safety compartment which then pass through into a thermofoil lined bladder compartment which houses a bladder capable of holding 4 liters or more of fluid and having a large dial with a hook that latches onto a loop in the bladder compartment so it remains upright at all times. Drainage ports on the bottom of the device allow for safety removal of fluid in the case of a leak. The spray hose exits the bladder compartment, is securable over the shoulder to a strap wherein the spray nozzle, made of metal, is securable via a magnet into a holster on one of straps.

A reusable fluid dispenser (100) and a disposable fluid pack (200) for use with the reusable fluid dispenser (100) is provided for dispensing fluids. Multiple different disposable fluid packs (200) may be interchangeably used with the same reusable fluid dispenser (100) such that multiple different fluids may be dispensed at multiple different flow rates, without cross contamination of the fluids. The reusable fluid dispenser (100) comprises a housing (102), a motor (106), a controller (114), a power supply (104) and a decoder (110) and a lens array (116). The disposable fluid pack (200) comprises a fluid reservoir (202), a pump (204) and an encoder (206).
