A flexible dispensing apparatus for coupling to pressurized fluid containers is described. It includes a flexible tube and a handle assembly. The handle assembly houses a second end of the tube. The handle assembly has a first side connected to a second side, a slide trigger, a roller coupled to the bottom of the slide trigger with a dowel pin, a spray nozzle assembly, a magnet reservoir, and a magnet. The first side has an inclined ramp that runs along a length of the first side and extends into the second side above and beyond a seam that is formed by the connection of the two sides. The tube is within a channel in the handle assembly formed between the inclined ramp and the roller. When the roller is rolled toward the end of the ramp it pinches the flexible tube near the top of the inclined ramp.

The invention relates to a pinch valve comprising at least a body having connecting flanges, a sleeve made of elastic material and an actuator, wherein said pinch valve comprises first pinching means that is movable towards the sleeve, wherein as a response to an operation of the actuator, said first pinching means squeezes the sleeve at least partially to control a flow in said sleeve. In the pinch valve, the sleeve is curved, and said connecting flanges are not parallel, whereupon said sleeve is fixed to the body in such a manner that openings of said sleeve are not parallel either.

A clamp for controlling fluid flow through a flexible tube has an electrically powered signal generator which can indicate the state of the clamp (closed or open) and thus indicate the state of fluid flow. Momentary switches controlling the signal generator provide versatility to the clamp. Visual, auditory and haptic signals are generated by the signal generator in response to a particular state of the clamp.

Pinch clamps are provided which generate positive displacement while also preventing rebound. To prevent rebound while providing positive displacement, the upper and lower clamping surfaces may be configured to form a pinch profile along which the tubing is compressed with the pinch point being formed at the distal end of the pinch profile. To further prevent rebound, the lower arm of the pinch clamp can include blocking ribs that interface with the upper clamping surface to prevent distal travelling of the pinch point even if the upper arm is forced into an over-engaged position

A clamp device for a flexible tube which can minimize the sealing area and prevent leakage of fluid and achieve easy release of the clamp device of a flexible tube. A clamp device for a flexible tube comprising: one branch formed with a first projection; the other branch formed with a second projection opposing to the first projection; an intermediate part connecting the one branch and the other branch each other; and an engaging part formed on a tip end of the other branch adapted to be engaged with an engaged part formed on a tip end of the one branch; flow of fluid within the flexible tube laid between the first projection and the second projection being able to be blocked by elastically bending the intermediate part and engaging the engaging part and the engaged part each other to clamp the flexible tube between the first and second projection wherein the clamp device comprises a positioning part for positioning the first and second projections in the longitudinal direction of the flexible tube under the clamped state of the flexible tube with engaging the engaging part and the engaged part each other.

A valve assembly for a leak resistance drinking cup is selectively configurable between a sealed position and an unsealed position. The valve assembly includes a plug having an inner surface, an outer surface, and an opening extending through the plug from the outer surface to the inner surface. An amount of vacuum acting on the outer surface of the plug needed to move the valve assembly from the sealed position to the unsealed position is less than the amount of internal pressure acting on the inner surface of the plug needed to move the valve assembly from the sealed position to the unsealed position.

A flexible dispensing apparatus for coupling to pressurized fluid containers is described. it includes a flexible tube and a handle assembly. The handle assembly houses a second end of the tube. The handle assembly has a first side connected to a second side, a slide trigger, a roller coupled to the bottom of the slide trigger with a dowel pin, a spray nozzle assembly, a magnet reservoir, and a magnet. The first side has an inclined ramp that runs along a length of the first side and extends into the second side above and beyond a seam that is formed by the connection of the two sides. The tube is within a channel in the handle assembly formed between the inclined ramp and the roller. When the roller is rolled toward the end of the ramp it pinches the flexible tube near the top of the inclined ramp.

An encapsulated valve system includes a first housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface. The valve system further includes a second housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface. A disposable conduit is configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface. The disposable conduit is thus sandwiched between the first and second facing surfaces. A plurality of pinch valve actuators are mounted on one or both of the first housing portion and the second housing portion, the plurality of pinch valve actuators configured to pinch the disposable conduit at selective branch pathways.
