An example portable fluid spraying system includes a handheld fluid sprayer. The handheld fluid sprayer includes a fluid reservoir configured to store a fluid, a pump configured to pump the fluid from the fluid reservoir to an outlet of the handheld fluid sprayer and a handle. The handheld fluid sprayer includes a first trigger proximate the handle, configured to control fluid flow to the outlet. The portable fluid spraying system includes a fluid hose having a coupling mechanism configured to removably couple to the handheld fluid sprayer proximate the outlet and a fluid spray gun. The fluid spray gun includes a gun inlet configured to couple to the fluid hose and receive the fluid from the handheld fluid sprayer, a gun outlet configured to expel the fluid in a spray pattern and a second trigger configured to control fluid flow to the gun outlet.

The invention relates to a spray device having a spray nozzle unit and at least one further spray nozzle unit. Each spray nozzle unit has at least one spray nozzle body, wherein at least one spray nozzle body comprises a chamber for receiving a pressurized fluid. The chamber is bound by a spray wall having at least one spray orifice that extends through the spray wall and opens to an external environment. Each of at least one orifice in a spray wall has a substantially identical predetermined size lying in a predetermined range and releases a mono disperse spray jet of the pressurized fluid fed from the associated reservoir. The range within the first spray nozzle unit differs from the range within at least one further spray nozzle unit; particularly, the ranges do not overlap.

The present disclosure provides a dispenser for pressurized material. In an embodiment, the dispenser for pressurized material includes a container half having an exposed edge and a closure member at the exposed edge. The container half has a cup half in an interior top portion. The dispenser includes a reciprocal container half having a reciprocal exposed edge and a reciprocal closure member at the reciprocal exposed edge. The reciprocal container half has a reciprocal cup half in an interior top portion. The closure member and the reciprocal closure member matingly engage along the exposed edges to attach the container half to the reciprocal container half and form a container. The dispenser includes a sleeve bag on valve (SBoV) assembly in an interior of the container. The SBoV assembly includes a valve seat. The cup and the reciprocal cup support the valve seat to secure the SBoV assembly in the container.

A nose-to-brain drug delivery device is provided. The nose-to-brain drug delivery device includes a freeze-dried drug container for storing a freeze-dried drug, a restoring solvent container for storing a solvent for thawing the freeze-dried drug, a membrane for preventing the freeze-dried drug from being mixed with the solvent, and a compressor for providing a driving force. The membrane is opened by the driving force of the compressor to mix the freeze-dried drug with the solvent, thereby thawing the freeze-dried drug, and the thawed drug is sprayed by the driving force of the compressor.

A device for delivering a compound to the olfactory region of the nasal cavity includes an actuator body and a tip configured to removably couple to the actuator body. The actuator body comprises a propellant channel in fluid communication with a propellant canister. The tip comprises a tip stem, a dip tube, a delivery channel, one or more puncture members, and an outlet orifice. The tip stem receives a compound container containing the compound and the compound container moves between a sealed state and an unsealed state. The one or more puncture members are each configured to puncture the compound container when the compound container is in the unsealed state. Propellant released from the canister travels through the propellant channel and into the punctured compound container, thereby contacting the compound and propelling the compound through the delivery channel and out the outlet orifice.

A device and method for the enhancement of performing fellatio is described. The device includes a bulbous member, a hose member, and a plurality of band members. The band members surround the shaft of the penis and are configured to route or locate the hose member. The hose member is positioned toward the glans of the penis. The bulbous member is filled with a liquid that is selectively dispensed by either participating party during fellatio. The liquid is routed to the glans for dispersion into the performer's mouth to be mixed with ejaculate. The liquid alters the taste of the ejaculate to enhance the fellatio experience for the performer.

Fluid delivery devices and methods are described, where the device may comprise a piezoelectric actuator operatively coupled to an ampoule with fluid, under a preloading force. The ampoule may comprise a thin-walled thermoplastic package which includes one or more apertures positioned on the wall of the ampoule. The piezoelectric actuator may be configured to clamp at least partially around the circumference of the ampoule and apply oscillations to its wall. The oscillations, typically in ultrasonic frequency, produce cycles of acoustic pressure in the fluid, leading to ejection of the fluid droplets or streams from the apertures.

In various embodiments, a fluid delivery pod includes a first surface, a second surface that opposes the first surface, a reservoir body, an outlet port, a heating structure, and a valve assembly. The reservoir body is between the first and the second surfaces. The reservoir body is configured to house a fluid. The outlet port is positioned on a surface of the pod. The surface is between the first and the second surfaces. The heating structure is thermally coupled to the fluid housed within the reservoir body. The heating structure wirelessly receives energy from an energy source that is external to the fluid delivery pod. The wirelessly received energy heats the fluid housed within the reservoir body. In response to an application of compression forces on the first and the second surfaces, the valve assembly dispenses the heated fluid through the outlet port and out of the fluid delivery pod.

A spray gun cup receptacle is disclosed comprising an open end for receiving a liner within a cavity and a base end opposite the open end. The sidewall comprises at least one aperture through which the cavity is visible from outside the spray gun cup receptacle. The apertures are divided one above the other by a brace member, at least a portion of which is disposed at a brace member angle relative to the base plane. Also disclosed are receptacles comprising one or more tactile feedback members positioned adjacent an aperture.

The present invention also provides a liquid reservoir assembly 10 of the type that can store and release a fluid under pressure, the assembly 10 having an outer body formed of an open ended tube 20 which is closed by end formations 70, 80 which engage respective ends of the open ended tube 20 and are held stationary with respect to the open ended tube 20, the end formations 70,80 holding between them an elongated elastic inner tube 30 sealing secured to the end formations, the elastic inner tube 30 being axially pre-tensioned or stretched from its natural or rest state, and secured to the ends in the pre-tensioned or stretched condition.
