A high flow volume nasal irrigation device includes a squeeze bottle, a reservoir of liquid and a volume of air. The bottle is configured to elastically deform in response to a manual pressure from a user and thus pressurize the liquid and air. The device also includes a dip tube configured to convey a pressurized liquid flow from a first end inside the bottle to a second outside end at a lower pressure. A removable nipple cap comprises an orifice and a coaxially aligned extension configured to seal with the dip tube and to form a conduit with the tube. At least one air metering orifice is formed in the fluid conduit accessible to the to volume of air. The air metering orifice is configured to introduce a plurality of air pockets from the air volume into the liquid flow and thus generate a pulsatile fluid flow in the conduit.

The invention relates to a foam-forming assembly for forming a foam, comprising a housing having an air passage and a liquid passage which each end in a mouth and which are in communication with a dispensing passage which ends in a dispensing opening, and a valve body. The invention is characterized in that the mouth of the liquid passage is annular and the mouth of the air passage and an entry port of the dispensing passage are substantially provided on the circumference of an imaginary circle, in which between the annular mouth of the liquid passage and the mouth of the air passage and/or the entry port of the dispensing passage an annular sealing surface is provided, against which, in rest position, the valve body sealingly engages, and in which during dispensing the valve body becomes detached of the sealing surface such that the mouth of the air passage, the mouth of the liquid passage and the entry port of the dispensing passage substantially simultaneously come in fluid communication with each other.

The invention relates to a dispensing device for dispensing a foam, comprising a manually compressible container (2) for storing a liquid and air, which container comprises an opening (3), a rigid housing to be fitted in or on the opening, the housing comprising an air passage (11) and a liquid passage (9) and a valve body (6) which, in a rest position, covers a mouth of the liquid passage and a mouth of the air passage in a sealing manner (4a, 4c) and which, during dispensing, opens the mouth of the liquid passage and the mouth of the air passage in order to allow mixing of air and liquid to take place in the dispensing passage (13). The invention is characterized in that the housing comprises a first housing part (4) and a second housing part (20), the first and the second housing parts being mountable in several position with respect to each other, the ratio between the amounts of liquid and air to be dispensed upon compressing the container being dependent on the position in which the first and second housing parts are mounted with respect to each other.

A quantitative dropper structure includes a resilient bottle body, a nozzle detachably sealingly connected to a bottle opening of the bottle body, and a transfer mechanism having a flow path formed of a first transfer pipe, a remaining liquid reservoir and a second transfer pipe. The nozzle has a dispensing orifice and a bottom wall formed with a perforation. The first transfer pipe has a first end communicating with the remaining liquid reservoir and a second end downward extending near to a bottom section of the bottle body. The second transfer pipe has a front end passing through the perforation to communicate with the liquid reservoir and a rear end communicating with the remaining liquid reservoir. When compressed, the liquid flows in the flow path into the liquid reservoir. After a predetermined volume of liquid is contained in the liquid reservoir, the liquid is quantitatively dispensed from the dispensing orifice.

The invention relates to a dispensing device for dispensing a foam, comprising a manually compressible container (2) for storing a liquid and air, which container comprises an opening (3), a rigid housing (4, 5) to be fitted in or on the opening, the housing comprising an air passage (11, 12) and a liquid passage (9), which are in communication with a dispensing passage (14) which ends in a dispensing opening (8), and a valve body (6) which, in a rest position, covers a mouth of the liquid passage and a mouth of the air passage (10) in a sealing manner in order to prevent a flow from the liquid passage and the air passage to the dispensing passage, and which, during dispensing, opens the mouth of the liquid passage and the mouth of the air passage in order to allow mixing of air and liquid to take place in the dispensing passage. The invention is characterized by the fact that the mouth of the air passage and the mouth of the liquid passage are—substantially annular and are arranged substantially concentrically with respect to one another.

The invention relates to a single-dose container fitted with a spray tip comprising a generally cylindrical nozzle, the upper end of which comprises a spray opening and the opposite end of which is extended by a plunger of smaller diameter, the free end of which is mechanically reinforced, the nozzle and the plunger being crossed along their longitudinal axis by a traversing cavity, said traversing cavity having at the nozzle a means of creating droplets; it also relates to the actual tip and to a spray kit comprising said nozzle and a pre-filled single-dose bottle.
摘要:
A fluid dispenser (100; 200; 300; 400) for dispensing a fluid in liquid or in powder form, the dispenser including a reservoir (12) serving to contain fluid, and a dispensing orifice (114; 214; 314; 414) via which the fluid is dispensed. The reservoir (12) having an actuating wall (111; 211; 311; 411) and a backing wall (112; 212; 312; 412), the walls be adapted to be brought towards each other by elastic deformation to reduce the volume of the reservoir, and thus to deliver fluid through the dispensing orifice. The dispenser further having a one-piece body (110; 210; 310; 410) and at least one flexible sealing film (120; 220; 320; 421; 422), the actuating wall and the backing wall being formed by the one-piece body, wherein the actuating wall and the backing wall are angularly positioned relative to each by forming an angle that decreases when they are brought towards each other.
