A vented pump includes a pump housing with a fluid retention cavity, a fluid inlet, and at least one vent opening therethrough. A pump dome is secured to the pump housing to form a dome cavity. Movement of the pump dome allows material from the fluid retention cavity to enter the dome cavity through the fluid inlet, and selectively allows ambient air to enter the fluid retention cavity through the at least one vent opening.

The present invention relates to an applicator having a press button for discharging gel-type contents, and more specifically, an applicator having a press button for discharging gel-type contents, the applicator comprising: a pump embedded in a container body; a pressing member coupled to the upper side of the pump; a link coupled to the pressing member; and a press button formed on the outside of the link. If the press button is pressed, the link is pressed, then the pressing member connected to the link presses the pump vertically, and thereby the gel-type contents filled in the container body are pumped, and discharged through a discharge member. Thus, a predetermined amount of gel-type contents can always easily be discharged for use.

A dispenser and applicator head (T1) having a connection stub (1) made of a substantially-rigid first material; an assembly core (2) made of the same material; a flexible link section (S) that interconnects the connection stub and the assembly core; an applicator pad (5) made of a heat-transfer material to impart a cold sensation on contact with the skin and mounted on the assembly core; and a dispenser channel (6) that passes through the stub, the link section, the core, and the pad in which it forms a dispenser orifice. The link section includes a flexible bridge (3) made of the same material as the stub and interconnecting the stub and the core; and sheathing (4) made of an elastically-deformable material, the sheathing surrounding the bridge, at least in part, and interconnecting the stub and the core.

The present invention relates to a gel-state content discharging applicator and, more particularly, to a gel-state content, discharging applicator wherein a pressurization button is formed on the lower end of a container such that, when the pressurization button is pressed, an inner container is pressurized, thereby pressurizing an inner container cap, which is coupled to the inner container, and a pump, which is coupled to the inner container cap; as a result, the gel-state content is discharged through a valve of the pump and through a discharge member such that a predetermined mount of gel-state content is always discharged easily; in addition, formation of the pressurization button on the lower end of the container guarantees that, when the container according to the present invention is used for tooth-related products among medications and sanitary aids, the content can be easily applied even to molar parts.

Dispensers are disclosed that are adapted to be coupled to a reservoir to dispense a fluid contained in the reservoir. A dispenser includes a pump having a pump chamber, an intake conduit, a discharge conduit, and a pulsation dampener. The pulsation dampener includes a housing with an interior volume and an opening. Further, the pulsation dampener includes a spring biased movable piston located in the interior volume and defines a variable volume headspace between the piston and the opening of the pulsation dampener, the opening being in fluid communication with the discharge conduit.

A dispenser capable of discharging a liquid material from a discharging opening includes a pump chamber capable of sucking the liquid material; a first communication port as an outlet provided in the pump chamber; and a first passage as a pathway provided to make the first communication port and the discharging opening communicable with each other and allowing the flow of the liquid material. The first communication port is positioned on the opposite side to the discharging opening across a central axis of the pump chamber.

The invention discloses an elastic bag foam pump, which comprises a bottle cover (1), an elastic bag (2), a piston rod (3), a piston (4), a liquid inlet one-way valve (6) and a gas inlet one-way valve (8), wherein the elastic bag (2) is a hollow thin-wall bag; the bag opening of the elastic bag is provided with a connection part (2.1); the connection part (2.1) is mounted on an annular wall (1.1) used for connection on the bottle cover (1) in a sealing way; the elastic bag (2) is provided with an inlet hole (1.8) through which an inlet pipe (2.4) is communicated with the bottle cover (1); the gas inlet one-way valve (8) is mounted at one side of the inlet hole (1.8); a piston rod upper end (3.1) is fixed to an upper wall connection part (2.3) of the elastic bag (2); the lower end of the piston rod (3) is provided with the piston (4); and a cylinder (1.2) is arranged in the middle of the bottle cover (1). The elastic bag foam pump has the advantages of simple structure, low cost and easy to use.

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.

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user's hand(s) in connection with an operation of the door handle to sanitize the user's hand(s).

A pump-type compact container is configured such that, when the user pressurizes a button portion, the button portion is moved downwards, and then restored by the elastic force of the button portion itself, thereby changing the pressure inside the container body and discharging the contents. Therefore, since contents having a high viscosity can be discharged easily through a simple structure, even if no separate pumping member exists, the assembly time is shortened and manufacturing costs are reduced.
