A dosing dispenser for dispensing a material comprising a housing, a container moveably arranged in the housing and including the material, a pump unit, and an applicator for material output. The housing includes an actuation member which facilitates moving the container in the housing relative to the pump unit, so that the pump unit is activatable by the container for suctioning and dispensing the material. The actuation member is formed by an opening in the housing for manual access to the container in order to move the container in a linear manner. Alternatively, the actuation member is configured as a slider element which is inserted into an opening of the housing and coupled with the container, wherein the slider element is translatorically moveable in the opening so that the container is moveable back and forth by the sliding movement of the slider element in order to activate the pump unit.

A method of assembling a fluid dispenser device, the method comprising the following steps: pre-assembling a first unit comprising a body (10) and a lateral actuator system (40), said lateral actuator system including a presser element (42) that is mounted on the body (10) to pivot about an axis (A), an actuator element (41) being mounted on said presser element (42) to pivot about an axis (B), said presser element (42) having a pre-assembled position in which said lateral actuator system (40) is blocked; assembling a second unit, comprising a dispenser member (30), such as a pump or a valve, that is mounted on a reservoir (20) by means of a fastener ring (60), in said first pre-assembled unit; and moving said presser element (42) from its pre-assembled position to a final assembled position that is axially offset from said pre-assembled position, and in which said actuator element (41) co-operates operationally with said fastener ring (60) so as to actuate said dispenser member (30) each time the lateral actuator system is actuated.

A device for dispensing a fluid product having a container (10), a dispensing member (20), a dispensing head (30) with an outlet (31), an actuating member (60) slidably mounted in the dispensing head, and a lateral actuating system cooperating with the actuating member. The actuating member has a cylindrical body (65) and a flexible tab (61) having a radial projection (62), the flexible tab extending axially into the cylindrical body (65) and radially deformable between an undeformed position, in which the projection (62) projects radially out of the cylindrical body, and a deformed position, in which the projection does not. The lateral actuating system has two side levers (35, 36) diametrically opposed, deformable and/or movable laterally, a flexible spacer (37) connecting the two side levers, the flexible spacer cooperating with the projection (62) and axially deformed during actuation to axially move the actuating member relative to the dispensing head.

The invention discloses a waterproof emulsion pump with an external spring, which includes a pump body extending into a bottle body, a pump chamber is arranged in the pump body, a locking bottle cover is connected to the pump body, a pumping component is arranged in the pump chamber, and a locking cover is connected to the pump body; a one-way valve is arranged at a lower end of the pump chamber, an upper end of the pumping component is connected with a pressing head capable of driving the pumping component to operate, the pumping component includes an upper pump rod, a spring is arranged between the upper pump rod and the locking cover, a lower end of the upper pump rod is connected with a lower pump rod, a liquid inlet groove opening is formed in the lower pump rod, a piston is sleeved on an outer side of the lower pump rod, a pushing part is arranged on the upper pump rod, and a protruding part capable of contacting with a lower end of the piston to push the piston to move upwardly is arranged on the lower pump rod; and a waterproof structure is arranged between the upper pump rod and the locking cover. The waterproof structure is arranged between the upper pump rod and the locking cover of the invention, so that external water or impurities can be prevented from entering the pump body from a gap of the pump body to pollute a material body, and the sealing performance of the emulsion pump is improved.

A dispenser container having a retractable nozzle is proposed. The container is configured such that an air pumping part (30) is coupled and secured to an upper portion of a container body (10) by a locking cap (20), a guide cap (20) configured to be movable up and down is coupled to the outer surface of the locking cap (20) at a location outside the locking cap, and a nozzle cap (50) configured to pressurize and operate the air pumping part while being rotated and being moved up and down in conjunction with the guide cap is coupled to an upper portion of the guide cap (40) at a location outside the guide cap so that the nozzle (60) coupled to the nozzle coupling hole formed at the side of the nozzle cap is extended and retracted in response to the rotation of the nozzle cap.

Disclosed is a dispensing bottle for storing and dispensing a fluid medium. The dispensing bottle comprises a container comprising a cavity for storing the fluid medium. The dispensing bottle further comprises a cap engaged with the container. The cap comprises a first portion and a second portion comprising a top surface disposed above the first portion. The dispensing bottle further comprises a pump engaged with the first portion of the cap and substantially disposed within the cavity. The dispensing bottle further comprises a spout engaged with the pump and extending outside of the cap. The spout being moveable between an open position where the spout extends away from the cap so the fluid medium may be dispensed and a closed position where the spout is disposed slightly above or in contact with the top surface of the second portion of the cap to prevent downward movement of the spout.

A plastic spring, a pump core, a lotion pump and a press-type packaging container. The plastic spring includes at least one spring unit. Each spring unit includes a first support member, a second support member, and at least two torsion arms. The at least two torsion arms are arranged between the first support member and the second support member, and both ends of each of the torsion arms are respectively connected with the first support member and the second support member. Each of the torsion arms includes at least one vertical section, and an end of each vertical section is connected with the first support member or the second support member.

Dispensing devices are provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. An example dispensing device has, for example, a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a container and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve. Liquid exiting the piston chamber under pressure enters a central vertical channel which is in fluid communication with both the pressure chamber and a dome valve, with pre-defined opening pressure, provided near the outlet channel at the top of the dispensing head.

A pump dispenser where the pump assemblies does not require disassembly to be recycled in current recycling streams. The pump assembly can include a plastic spring that does not lose stiffness over time and does not interact with the liquid product.
