Abstract:
An inhaler including a pre-inserted cartridge (100) is proposed. The cartridge contains liquid (103) which is preferably pressurized to a low pressure. The cartridge is connected via an aerosol valve (106) with the inhaler. The liquid is further pressurized by a pump (117) of the inhaler to a high pressure and atomized.
Abstract:
Fluid mixture which comprises at least one low-boiling liquid, and which during use generates a low vapour pressure, said mixture being dispensable by a manually operated dispensing pump mounted on a hermetically sealed container of this mixture. The low vapour pressure developed by the low-boiling liquid is such as to prevent a vacuum being created in the container interior when the mixture is dispensed by the pump, in order to allow correct pump operation.
Abstract:
A pump enabling a fluid substance to be manually dispensed through a hollow stem projecting from a hole in a ring cap sealedly applied to one end of a pump. The stem can sealedly translate within said hole in the ring cap, which in its turn can be sealedly mounted on the mouth of a container containing the fluid substance to be dispensed.
Abstract:
The invention provides a liquid dispenser 2 comprising a mostly rigid body including tow spaced-apart major surfaces 8 and 10 having interconnected peripheral edges 12 to delimit there between a closed dispensing body having a liquid to be dispensed contained therein, a pumping chamber 5 having an inlet valves 6 and a non-return product dispensing valve 7 and actuated by a pumping button 9 provided along one of the major surfaces 10 and dispaceable between a first normal position and a second expressed position, the arrangement being such that the dispenser is formed as a compact, self-contained unitary container and pump, wherein said pumping button 9 is formed as an integral part of one of said major surfaces 10 and serves as a wall of said pumping chamber 5, and depression of the pumping button 9 to its displaced position causes liquid contained in the pumping chamber 5 to be expelled via the product dispensing valve 7, and return of the button to its first normal position causes liquid to enter the pumping chamber 5 via the inlet valve 6.
Abstract:
The present invention relates to a contents dispensing pump which is coupled to a container (V) for accommodating the contents therein and dispenses the contents, comprising: a pump main body (10); a pump upper body (20); a pump inner body (30); a dispensing valve (40); and an elastic member (50). The pump upper body (20) is coupled to the upper side of the pump main body (10) so that a pumping operation is made by an up and down movement with respect to the pump main body (10). The pump inner body (30) has a bowl shape with the middle thereof formed to be dented so that an inlet valve plate (70) is integrally formed on the lower surface. The dispensing valve (40) is coupled to the upward side of the pump upper body (20), and has, formed therein, a valve protrusion wheel (41) for opening and closing the content outlet (23). The elastic member (50) is positioned between the upper lateral surface extension piece (33) and the lower lateral surface extension piece (34) of the pump inner body (30) so as to draw the pump inner body (30) and simultaneously elastically support the pump main body (10) and the pump upper body (20).
Abstract:
A device for dispensing fluid from a fluid container, the device capable of being set to different discrete and repeatable/equal dispensing amounts, depending on the amount of fluid required to be dispensed by the user for various applications and uses. The device may also be set to an “off” or “closed” position to prevent accidental dispensing of fluid when not in use. The device is preferably configured to be affixed to the outer surface of a fluid container, which fluid container is preferably a flexible bag or pouch.
Abstract:
The invention relates to a metering pump for a metering device for metered dispensing of a liquid, which can be connected to a storage container, comprising a cylindrical pump body and an actuation body.

Abstract:
A kind of foam spray gun, comprising a gun body, a nozzle, a trigger, a one-way liquid inlet mechanism, a piston rod, a piston, a resetting piece, a one-way valve and 2 foaming screen meshes, said gun body being provided with a foam generating channel, said piston sleeve being mounted on the inner side of said trigger and moving inward under the driving force of said trigger and engaged with said gun body, said piston being mounted on inner cavity of said piston sleeve and moving together with said piston sleeve and engaged with said gun body to form the first cavity and the second cavity, said one-way valve and foaming screen meshes being mounted inside the foam generating channel of said gun body. Compared with existing technologies, this patent is advantageous in that: it organically combines the foam generating mechanism formed by the one-way valve and one-way valve sidepiece with first cavity and second cavity of the gun body, allowing the liquid to be gathered at the liquid outlet of the one-way valve to form foams and then enter the screen mesh for secondary foaming, which ensures rich foams as well as reasonable and practical structure, moreover, it adopts the trigger type, which is simple and continent, labor saving and provided with fine handle for repeatedly operation.
Abstract:
Apparatus for metering and dispensing fluid includes a fluid dispensing section having an exit orifice, a fluid inlet, and a pathway extending from the fluid inlet to the exit orifice. A portion of the pathway includes a hydrophilic portion for metering a volume of the fluid when the dispensing section is upright; and a hydrophobic ring at the fluid inlet for preventing a metered volume from flowing out of the hydrophilic portion when the dispensing section is upright. The apparatus further includes a one-way valve between the exit orifice and the hydrophilic portion for allowing fluid to flow out of the hydrophilic portion and toward the exit orifice when sufficient pressure is applied to the fluid inlet. The one-way valve also prevents fluid from flowing through the exit orifice when the hydrophilic portion is being filled with fluid.
