This application relates to a fluid dispenser. In one aspect, the dispenser includes a body including an opening and an accommodating space for accommodating fluid, a lid for closing the opening, a pressing unit disposed on a side of the body, and a discharge unit disposed on the side at a position diagonally higher than the pressing unit and configured to discharge a predetermined amount of the fluid from the accommodating space when a pressure is applied to the pressing unit. The dispenser may also include a pump mechanism configured to pump the predetermined amount of the fluid from the accommodating space to the discharge unit when the pressure is applied to the pressing unit, and an air intake formed on a part of the lid and configured to flow air into the accommodating space when the predetermined amount of the fluid is discharged from the accommodating space.

The present disclosure relates to a two-way pumping device for consumption of a residual amount of a liquid. The two-way pumping device includes a vessel, a body portion including first and second chambers for storing a liquid, a suction pipe extending to the outside of the body portion, a first bearing for opening and closing the suction pipe, a pump portion including a head portion protruding outside the body portion, a first piston slidably moving in the first chamber, a second piston slidably moving in the second chamber, a first discharge portion that discharges a fluid in the first chamber to the outside, a second discharge portion that discharges a fluid in the second chamber to the outside, a spring that applies an elastic restoring force to the pump portion, and a suction portion capable of causing a liquid to flow into the second chamber.

A pump system may include a blown-in dip tube connected to a valve body and having a connection which may include an improved blown-in dip tube connector having one or more of a lip for sealing with a blown-in dip tube, a seal ring configured to mate with a blown-in dip tube and seal therewith, a dip tube lock for mating with a blown-in dip tube, or an o-ring for providing an improved seal with a blown-in dip tube.

The ejection head includes a pressing member; a nozzle tip that is fitted to a concavity; and an insert member. The insert member includes: a concave portion that forms a filling space for the content medium; at least one through hole formed on a circumferential wall; and a long groove that extends from the through hole to the nozzle tip. The insert member has a front end having an outer circumferential edge formed as an annular inclined surface, and the front end is formed with a bulging portion. The bulging portion is formed with a plurality of radial grooves and a cylindrical groove. At least one through hole is located in a position that is circumferentially offset from the plurality of radial grooves.

An apparatus for pumping a selected sterilizing fluid by a user comprising: a fluid container, a pump assembly having a fluid delivery tube, the fluid delivery tube being manually drivable by the user in a downstream direction starting from a stationary start position and adapted to pump fluid upstream through an upstream end of the fluid delivery tube that is configured to receive and engage a complementary surface of an external device, the fluid delivery tube being drivable downstream from the start position by manually engaging the complementary surface of the external device against the upstream facing surface of the enlarged head and manually driving the external device in the downstream direction.

A liquid dispenser, having a large ring, a connecting cover, and a hollow pump frame, the pump frame is movably clamped to the interior of the large ring, the top of the pump frame extends to the outer side of the top of the large circle, a bottom protruding portion of the connecting cover extends into a top groove of the pump frame so as to be movably clamped thereto, a first air outlet is provided on both sides of the bottom of the connecting cover, and a second air outlet in communication with the first air outlet is provided to penetrate through the pump frame. The first air outlet, the second air outlet, the first liquid outlet, and the second liquid outlet can be opened and closed by rotating the connecting cover to change a position relationship between the connecting cover and the pump frame.

A spray dispenser is provided, the spray dispenser comprising a container for holding a liquid to be dispensed and a dispensing assembly for extracting liquid from said container, the dispensing assembly comprising a pressure-relief valve for release of excessive pressure in the container and a filter arranged to permit egress of gas through the filter, inhibit egress of liquid from the container and to inhibit ingress of contaminants into the container through the pressure relief valve. A dispensing assembly for use is a spray dispenser is also provided.

Various embodiments are directed to a fluid container comprising at least two fluid dispensing paths, wherein the fluid container comprises a container body and a fluid dispenser, wherein the fluid dispenser comprises a dispenser body connected to the container and a bottom portion enclosing the container. The dispenser body comprises a flow path extending through the bottom portion to a flow path exit, and a conduit aperture extending through the bottom portion and configured to accept a flexible conduit therein. A dispenser cap is operably connected to the dispenser body, wherein the dispenser cap comprises a fluid pump configured to pump fluid from the container via the flexible conduit. The dispenser cap is operable between a closed configuration in which the flow path exit is sealed and an open configuration in which the flow path exit is open, enabling fluid to flow out of the container via the flow path.

A trigger dispenser device (1) envisages a secondary liquid aspiration duct (50) in communication with the dispenser duct, and a primary liquid aspiration duct (8) in communication with the container, off-axis with each other. Between these, a joining compartment (64) is provided communicating upstream with the primary liquid aspiration duct (8) and communicating downstream with the secondary liquid aspiration duct (50) to form the fluidic connection between them. In particular, the container (C) is of the type with built-in suction pipe.

A dispensing closure system includes an upper closure portion and a lower closure portion including an axial flow conduit and a vent conduit. The upper closure portion is axially movable relative to lower closure portion between shipping and dispensing positions. A seal is disposed on the lower closure portion over the flow and vent conduits. A peripheral spacing strip is removably secured to the upper closure portion and engages with either the lower closure or the outside of the container to prevent movement. A piercing probe includes piercing elements in alignment with the flow and vent conduits for piercing the seal. In the shipping position, the piercing elements are spaced from the seal. However, when the spacing strip is removed and the upper closure portion is axially moved to the dispensing position, the piercing elements pierce the seal to open the flow conduit and the vent conduit.
