Abstract:
A device comprises a first portion including a first polymer, and a second portion that is relatively flexible in comparison to the first portion and includes a second polymer that is substantially not bondable to the first polymer. A chamber of the device is hermetically sealable with respect to ambient atmosphere and is defined by (i) an interior of the second portion, and/or (ii) a space formed between the first and second portions. A third portion of the device includes a third polymer that is bondable to the first and second polymers and fixedly secures the first and second portions to each other.

Abstract:
Apparatuses and techniques are provided for dispensing fluid from a dispenser that includes a flexible membrane having different levels of pliability according to a voltage applied to the flexible membrane. According to some embodiments, a biasing device, such as a spring, is disposed on a first side of the flexible membrane and is configured to apply pressure to the flexible membrane. When a first voltage is applied to the flexible membrane, the flexible membrane becomes sufficiently pliable to enable the spring to flex the flexible membrane, pushing the flexible membrane into a pumping chamber disposed on the opposite side of the flexible membrane relative to the spring. The fluid is stored in the pumping chamber and the flexing of the flexible membrane causes the pumping chamber to compress. Such compression of the pumping chamber forces the pumping chamber to dispense the fluid through a pump outlet.
Abstract:
Pump operable manually or by a utensil held by a user, having an elastically deformable chamber, the inside of which contains a liquid or viscous product, and the outside of which is brought into contact with air at a slit made in this chamber and with a replacement fluid at an opening made on the chamber. The chamber is suited to deforming, by pressing of a user, to create a higher pressure in the product compared to the outside, and to open the slit, allowing a volume of product to escape from it. The chamber is suited to making its deformation elastically disappear, upon cessation of the pressing, to create a lower pressure in the product, in the presence of a flow of replacement fluid through the opening towards the inside, and to close the slit, where the chamber wall is planar in the vicinity of the slit.
Abstract:
A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.
Abstract:
A Dispenser of fluid product includes a ring nut (2) able to be associated with a container of a fluid product and a dispensing head (7), substantially hollow and coaxially slidable relative to the ring nut. The dispensing head includes a dosing chamber (13) positioned inside the dispensing head, a dispensing nozzle (11) to allow escape of the fluid product. The dispensing head further includes a deformable membrane (14) fastened to the ring nut and a top wall (9) facing the membrane and defining the dosing chamber in combination with the membrane; the top wall being movable between a first position, distal from the ring nut, in which a volume of the dosing chamber is greatest and the dosing chamber is isolated and at least in part filled with fluid product, and a second position, proximal to the ring nut, in which the volume of the dosing chamber is smallest.
Abstract:
Pump operable manually or by a utensil held in one hand by a user, characterised in that it comprises an elastically deformable chamber (10), the inside of which is suited to containing a liquid or viscous product (8) and the outside of which is intended to be brought into contact with air at a slit (7) made in this chamber (10) and brought into contact with a replacement fluid at an opening (6) made on said chamber, in that the chamber is suited to deforming elastically, by a pressing of a user, to create a higher pressure in the product (8) compared to the outside, and to open the slit (7), allowing a useful volume of product (8) to escape from it, in that the chamber (10) is suited to making its deformation elastically disappear, following the cessation of the pressing of the user, to create a lower pressure in the product (8), in the presence of a flow of replacement fluid through the opening (6) towards the inside, and to close the slit (7), and in that the wall of the chamber (10) is essentially planar in the vicinity of said slit (7).
Abstract:
A manually actuated pump dispenser (210) has a dispenser main body (212, 214) including a first pump chamber (228) for a first fluid. An actuator (216) is mounted to the dispenser main body for movement towards and away from the dispenser main body. A flexible wall member (266) extends between the dispenser main body and the actuator to define a second pump chamber (268) between the dispenser main body and the actuator for a second fluid. The flexible wall member (266) is attached at one end to the actuator or to a part of the dispenser main body and has a distal end (266A) comprising a collar (265) which is mounted to the other of the actuator and a part of the dispenser main body to form a seal therewith. The flexible wall member may be formed integrally with the actuator or the part of the dispenser main body and the collar, for example by using bi-injection techniques. A method of manufacturing the pump dispenser is also disclosed.
Abstract:
A manually operated dispenser of the type containing a diaphragm at the bottom of the bottle, such that when the diaphragm is compressed a quantity of fluid is dispensed above the bottle through a spout. This invention uses a unique diaphragm shaped like a blister, that is integrated into the bottle bottom with a slide-pin allowing the blister diaphragm to move up and down, but not side to side. The diaphragm seals to the bottle bottom during dispensing, but when the diaphragm is substantially compressed, the seal self breaks as the diaphragm edge expands radially from the diaphragm axis over bumps on the bottle bottom allowing the diaphragm to refill. At the fluid output of the spout is a channel valve nozzle that channels the fluid into a stream when the fluid flows, but when the fluid is not being dispensed, prevents fluid from flowing back into the bottle.
