A spray pump is disclosed. A spray pump according to an aspect of the present invention comprises: a housing having an inflow space, the housing being coupled to a container entrance; a housing cover coupled to the upper end of the housing; a disk for opening or closing the housing according to the pressure in the inflow space; a valve movably inserted into the housing cover, the valve comprising a valve head and a valve body communicating with the valve head; a guide having a part inserted into the valve body and the remainder positioned on the outside of the valve body, the guide having a guide passage corresponding to a channel through which content is discharged; a valve spring for providing an elastic force that pressurizes the valve upwards; a piston movably inserted into the outer peripheral surface of the guide so as to open or close the guide passage by means of upward/downward movements of the valve; a nozzle coupled to the valve head and having an insert insertion portion; and an insert inserted into the insert insertion portion and having an orifice. The valve head has a valve passage communicating with the guide passage. The valve passage has a valve helical groove formed on the inner peripheral surface thereof.

The present invention provides a method, system and apparatus for refilling a reservoir of a smoking-substitute device with liquid from a dispenser.

A discharge head for a liquid dispenser having a base, an actuation handle, a liquid inlet and a discharge opening. The discharge head has a pump mechanism which conveys liquid from a liquid store to the discharge opening. To control liquid to be discharged and/or inflowing air, the discharge head has a valve with a valve flap which closes a valve channel and transfers to an open position by a positive pressure that exceeds a threshold positive pressure. The discharge head has an effector element bearing on the handle and the base, which deforms when the handle is pressed down. The valve flap is designed and attached to the effector element such that the deformation of same acts on the valve flap so that the threshold positive pressure, beyond which the valve flap leaves its closed position, is at least 10% lower in an actuated end position than in a non-actuated end position.

A piston pump for dispensing fluid from a reservoir, an improved vacuum relief arrangement in which a passageway for flow of air from the atmosphere into the reservoir is provided at least in part through a piston-forming element of the piston pump.

A dispenser pump is constituted by a closure body (2), a diaphragm body (3) which forms a pump chamber with the closure body and optionally a top actuator (4) for pressing the diaphragm body (4). The diaphragm body has a deformable wall (35) formed integrally in the same polymer as its annular mounting portion (31). An inlet valve (5) through the floor (21) of the closure body has a flap (52) which is formed and hinged integrally with that floor (21). An outlet valve may also be formed in the same polymer, either integrally with the diaphragm body or as a separate component. The deformable wall of the diaphragm body is shaped to generate a restoring force itself without a separate spring, so that the entire pump may be made from the same polymer e.g. polypropylene and without metal components.

Liquid dispenser having a liquid store and a discharge device fitted thereto and having a discharge opening. The discharge device has a pump device with a pump chamber variable in terms of volume and connected at an input side in a communicating manner to the liquid store and at an output side in a communicating manner to the discharge opening. The pump device conveys liquid from the liquid store to the discharge opening. The discharge device has a ventilation channel, by which an incoming air flow is enabled for pressure compensation between the liquid store and a surrounding atmosphere. The ventilation channel has a ventilation valve openable by manual actuation of the pump device and closed when the pump device is not actuated. Further, the ventilation channel has a capillary channel portion through which the incoming air flow reaches the liquid store.

A dispensing pump mechanism is provided. The pump comprises integrally molded temper-evidence part between a container collar and a spout; said collar has multiple off-centre outlet channel for dispensing one or more products from the container; said collar also comprises an integrated air vent to be blocked and opened by the rotation of the spout. The whole pump can be over-molded one-piece structure with elastic parts as being actuating parts. The pump improves the functions of the pump, such as lower restitution rate, less structural parts, lower cost, water/dust proof, lightweight, easy assembly.

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.

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 delaminatable container is capable of suppressing deterioration of the contents under high-temperature environment. The delaminatable container includes a container body; and a tubular outer case being installed in the container body; wherein: the container body includes an outer shell and an inner bag, and the inner bag shrinks as contents decrease.
