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.

Provided is an orifice and a spray container including the same. The orifice, which is provided at an outlet of the spray container, includes: an inflow part formed in a hollow cylindrical shape into which a nozzle is inserted and configured to receive contents flowing in through a circumference of the nozzle; a ring part recessed to a predetermined depth in a discharge direction from a circumference of a front surface of the inflow part; a discharge path provided at a center of the ring part and having a cross-sectional area decreasing in a direction toward a front; a wing part extending from the ring part toward the discharge path; and a discharge port provided at a front end of the discharge path.

Disclosed is an heterogeneous contents mixing vessel including: a first vessel formed therein with a content storage space and a discharge device accommodation space that are separately defined; a second vessel coupled below the first vessel; first and second discharge devices configured to discharge contents stored in the first vessel and contents stored in the second vessel, respectively; and a push button configured to simultaneously actuate the first and second discharge devices and formed therein with first and second discharge passages connected to the first and second discharge devices, respectively, and first and second discharge ports, wherein a connection grooves is formed in the first vessel and an inlet portion is formed in the second vessel so as to be coupled to each other, so that a separated second discharge device is connected through a connection member.

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 pump has a plunger operable in a body including an outer cylinder body having a vent opening in its sidewall and a body insert fitting into the top of the outer body and providing an external collar through which the plunger stem operates. The body insert has lock-down threads to lock down the plunger for shipping. The insert also has formations for blocking or unblocking the vent opening by rotation between the outer body and body insert, driven by rotation of the plunger head which makes a catch engagement with the top of the body insert. This plunger head rotation is the locking or unlocking action for the plunger lock-down. Blocking the vent during shipping reduces leakage.

A system for dispensing a personal care fluid, such as a hand soap or the like. The system includes a dispenser and a refill cartridge. The dispenser includes a dispenser body having a refill cavity and a dispenser lid configured to be coupled to the dispenser body. There may be a pump sub-system mounted to the dispenser lid, or alternatively the personal care fluid may be dispensed by squeezing the dispenser and refill cartridge. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The personal care fluid system is designed so that a user can readily and easily change out/replace the refill cartridge for use with a common dispenser, dispenser lid, and pump sub-system.

Provided is an orifice and a spray container including the same. The orifice, which is provided at an outlet of the spray container, includes: an inflow part formed in a hollow cylindrical shape into which a nozzle is inserted and configured to receive contents flowing in through a circumference of the nozzle; a ring part recessed to a predetermined depth in a discharge direction from a circumference of a front surface of the inflow part; a discharge path provided at a center of the ring part and having a cross-sectional area decreasing in a direction toward a front; a wing part extending from the ring part toward the discharge path; and a discharge port provided at a front end of the discharge path.

A pump assembly for a pump dispenser, the pump assembly comprises a cap having a housing and a spout, a collar, a sleeve, and a dip tube. The sleeve is at least partially positioned within the collar and comprises a coupling member. The coupling member comprises a shoulder, a coupling joint, and a coupling member channel extending from the shoulder to the coupling joint. The dip tube has a first end and an opposing second end, and defines a dip tube channel extending from the first end to the second end. The first end of the dip tube is configured to pivotally couple to the coupling joint and fluidly connect the dip tube channel and the coupling member channel. The dip tube channel comprises a first diameter at the first end and second diameter at the second end that is different than the first diameter.

The invention discloses a pump with a left and right locking structure and an external spring, which includes a pump body extending into a bottle body, a pump chamber is arranged on the pump body, a locking bottle cover is connected to the pump body, a pumping member is arranged in the pump chamber, a locking cover is provided at an inner wall of the pump chamber, a one-way valve is provided at a lower end of the pump chamber, a bent nozzle is provided at an upper end of the pumping member, a liquid guiding pipe capable of extending into the bottle body is arranged on the pump body and located below the one-way valve, the pumping member includes a pump rod, a liquid inlet hole is formed below the pump rod, a piston is sleeved on the pump rod, an air inlet hole is formed in the pump body, a pushing part is arranged on the pump rod, the locking cover is further provided with a limiting protruding block, and a reset spring is arranged between the locking cover and the bent nozzle; and a limiting member capable of preventing the bent nozzle from being pressed downward when the pump rod is rotated by a certain angle is arranged between the pump rod and the locking cover.
