In one embodiment, a self-cleaning nozzle comprises a nozzle body, a sleeve surrounding a proximal end of the nozzle body, a pillar disposed within the nozzle body and a spring. The nozzle body may have a hollow cylindrical interior. The nozzle body may include an orifice formed in a distal end of the nozzle body, a shoulder formed on a proximal end of the nozzle body, and a first bearing surface on an outer lateral face of the shoulder. The sleeve may include a second bearing surface on an inner face of the sleeve and a retaining lip formed at a distal end of the sleeve. The retaining lip may define a distal end of an annular space between the sleeve and the nozzle body. The shoulder may define a proximal end of the annular space. The pillar may have a distal tip configured to interface with the orifice, thereby forming a liquid seal. The spring may be captured within the annular space, thereby biasing the distal tip of the pillar into contact with the orifice.

A finger spray pump for spraying a medium has a finger-actuated pump head movable between a spraying position and an initial position. The pump has an outlet nozzle and a pump chamber with an inlet valve and an outlet valve, a piston rod, a pump piston, a first spring acting between the piston rod and the pump piston, and a second spring acting between the piston rod and the pump housing. The pump piston is movable between a sealed position and an open position, to form the outlet valve, wherein the pump piston in the sealed position lies on a sealing extension of the piston rod and in the open position allows the passage of medium between the sealing extension and the pump piston. The pump piston is supported on two zones of an outer surface of the piston rod that are axially spaced apart.

To provide a trigger sprayer that can maintain uniformity of a chemical solution containing fine powder and is superior in flow efficiency. The trigger sprayer of the present invention is designed such that a piston part 5 is moved by a pivotal movement of a trigger part, while being attached to a container, so as to apply a pressure to a liquid inside a cylinder part 42A of a cylinder structural part 4 so that the liquid in the container is jetted from a nozzle part 3 through a passage P. An F valve 2 attached to a bottom part of the cylinder part 42A serving a passage between the cylinder part 42A and the container and an S valve 1 installed in a passage part P between the cylinder part 42A and the nozzle part 3 are installed, and the F valve 2 is constituted by a cylinder-shaped base part 22 and a second valve body 21 having a sealing function as well as a small spring 22A coupling the cylinder-shaped base part 22 and the second valve body 21 to each other, and the second valve body 21 is further provided with a lower face part and a tilt part 21A on an opposite side, and the lower face part is fitted into the bottom part of the cylinder part 42A to be fixed therein, with the second valve body 21 being resiliently made in contact with a second valve mount 42A1 formed on the bottom part of the cylinder part 42A, and by pushing the tilt part 21A of the second valve body 21 by the bottom part of the piston part 5, the second valve body 21 is tilted so that one portion thereof is separated from the second valve mount 42A1, thereby opening the valve.

The present disclosure provides a feeding container device, including a bottle body having a bottle inner cavity, a first cover body at least partially disposed inside the bottle inner cavity and fixedly connected to the bottle body, a second cover body at least partially disposed inside the bottle inner cavity and having a cover inner cavity, a sealing ring disposed inside the bottle inner cavity and blocking the cover inner cavity, and a feeding device fixedly connected to the second cover body, the second cover body is mounted to the bottle body, the sealing ring is detachably connected to the second cover body and abuts the first cover body; when the second cover body moves away from the bottle body, the first cover body causes the sealing ring to separate from the second cover body, and the first sealed chamber communicates with the second sealed chamber.

A dispenser for dispensing a flowable product from a container has a pump module mounted on the container at an opening thereof. The pump module includes a pump body, which defines a pump chamber and a pump chamber inlet for product to flow from the container interior into the pump chamber. A pump actuator is operable in a pumping stroke relative to the pump body to vary the volume of the pump chamber and dispense the product. The pump includes a movable body portion which is operable in a displacement stroke into the container. The movable portion has a displacement body with a product-engaging face directed onto an interior product space of the container upstream of the pump chamber inlet, to assist priming. Below this a disrupter member, a grid of narrow bars, projects to penetrate the product.

A dispenser includes a depressible thermal tip and a housing having a reservoir for containing a product, such as a cosmetic product or a medicinal product. The depressible thermal tip comprises a thermal applicator displaceable between open and closed positions. The thermal applicator may be depressibly coupled in a collar fixed to the housing, or the thermal applicator may be depressibly coupled in a button depressibly coupled in a collar fixed to the housing.

A finger spray pump for spraying a medium, which includes a finger-actuated pump head, an outlet nozzle and a pump chamber which includes an inlet valve and a pump piston which can be moved by moving the pump head. The medium passes through a medium path between the pump chamber and outlet nozzle, additionally, the pump piston forms, in cooperation with a piston rod, an outlet valve and the pump piston can be moved with respect to the piston rod counter to the force of a first spring for actuating the outlet valve, the piston rod can be moved counter to the force of a second spring. Additionally, both springs are arranged outside of the medium path. In order to obtain a compact design, both springs are arranged at a distance from each other, axially independent from the pump position.

The present invention relates to fluid dispensing devices for use in dispensing different liquids (e.g., bleach and bleach activator) from a bottle having first and second compartments. To minimize the presence of mixed composition residually present within the fluid dispensing device, it may be helpful to delay mixing. Separate dip tubes may be provided to pull liquid from the separate compartments, each with its own separate pump. Each pump may deliver the separate compositions to a spray nozzle of the device through separate delivery tubes (e.g., from the pumps to the nozzle). In other embodiments, a single delivery tube, and/or a single pump may be provided, e.g., where the volume of mixed composition that may be present in such pump and/or delivery tube may be sufficiently small so as to still provide overall desired efficacy characteristics. Dual delivery tube configurations may eliminate any need to prime the device by spraying out old, residual mixed composition.
