A self-priming-pump-equipped packaging bottle includes a tubular bottle body containing therein an upper seal assembly, a lower seal assembly, and piston from top to bottom. The upper and lower seal assemblies and the tubular bottle body form a closed material-feeding chamber. The lower seal assembly, the piston, and the tubular bottle body form a closed material-storing chamber. The lower seal assembly primarily has a seal seat with a through hole and an elastic sealing gasket covering the through hole from above. The upper seal assembly has an umbrella-shaped member, a hollow material-feeding column, a support post, and an end sealing cap. The end sealing cap is fixed in the umbrella-shaped member through the support post. The hollow material-feeding column's bottom surface, the support post, and the end sealing cap form a material outlet. The umbrella-shaped member lower end is in interference fit with the seal seat.

The present disclosure relates to a technical filed of daily chemical products, and discloses a pump head and a container with the pump head. The pump head includes a shell body, and an suction chamber is provided in the shell body; a piston body is slidably provided in the suction chamber; a pump nozzle connected with the piston body is slidably provided at the shell body; an one-way valve is provided at the piston body; a squeezing opening communicated with the pump nozzle is provided on the piston body; the one-way valve is configured to close the squeezing opening; and the squeezing surface is inclined from a position away from the squeezing opening towards the position close to the squeezing opening.

An all-plastic emulsion pump, includes a body, threads, pressing head, main column, suction tube, plastic spring, pull rod, stopper, lock cover, first and second one-way valve devices made of plastic material. A communication port is between the plastic spring and the main column. The pull rod is in the plastic spring. The stopper is connected to the pull rod upper end. When the plastic spring is pressed, there is a gap between the pull rod and the side wall of the communication port. When the plastic spring pops up, the stopper blocks the communication port. The first one-way valve device is between the pressing head and the main column to supply the emulsion to the pressing head. The second one-way valve device is between the plastic spring and the inlet of the body to supply the emulsion from the inlet of the body into the plastic spring.

Disclosed are self-sealing actuators and pumps for distributing fluids such as personal care products. The actuator can include a nozzle having an outlet that is opens and closes via movement of a plug. A limit rod is configured to engage with the plug and upon actuation the assembly opens a passage for the fluid to flow through an inner channel of the limit rod and to the outlet. Upon de-actuation, the assembly closes the passage sealing the fluid within a closed environment to prevent degradation and caking. Actuators and pumps as described protect the performance of active ingredients within the fluid and prevent the nozzle and outlet from blocking with dried or caked fluid.

A pump for dispensing a fluid, has a pump head , a piston body with a piston, a pump chamber limited by a pump chamber body, an inlet valve and an outlet valve, the piston being moveable by respective movement of the pump head between an upper starting position and a lower end position. A return stroke force for a return stroke from the lower end position into the upper starting position is provided by a bellows, formed by two bellows arranged one above the other, Each of the bellows is folded up, when moving the pump head into the lower end position, by exerting a compression force on the pump head, the first bellows receiving the compression force by direct engagement with the pump head, the second bellows receiving the compression force only by engagement with the first bellows.

A pumping type of cosmetics container equipped with a side button, wherein the container is configured such that a pumping action occurs and contents are discharged when the user pressurizes a button part and the button part elastically deforms due to own elastic force of the button part, thereby making it possible to easily discharge the contents by means of a simple structure even without the presence of a separate pumping member, and thus making it possible to not only shorten the assembly time but also to reduce manufacturing costs.

A device for distributing a liquid. The device includes a bottle including a reservoir designed to store liquid, and a distribution element, and a concealment assembly. The distribution element allows the liquid to be distributed from the inside to the outside of the reservoir. The concealment assembly includes a base and a concealment ring that is movable along a main displacement axis from a first, operating position, to a second, locking position. The displacement of the concealment ring occurs through a helical movement of the concealment ring relative to the base in relation to the main displacement axis. As well, the displacement of the concealment ring from the operating position to the locking position allows at least part of the distribution element to be concealed. Finally, the concealment element further includes a ballast rigidly connected to the concealment ring.

A fluid dispenser comprising:

a reservoir (1);

a dispenser head (T) that is provided with a dispenser orifice (62);

a dip tube (22) that conveys the fluid from the reservoir (1) to the dispenser head (T);

a pusher (6) that is axially movable over a determined stroke;

an electric pump (4) that delivers air into the reservoir (1) so as to force the fluid through the dip tube (22) as far as the dispenser head (T), the electric pump (4) being actuated by the pusher (6); and

a fluid outlet valve (7);

the fluid dispenser being characterized in that:

all of the air coming from the electric pump is delivered into the reservoir;

the electric pump (4) is activated by the pusher (6) as soon as it leaves its high rest position, and the outlet valve (7) is opened only in the proximity of the low depressed position, such that the electric pump (4) is electrically powered well before the outlet valve (7) is opened; and

the electric pump (4) delivers air into the reservoir (1) with an increase in pressure that is less than 1 Bar.

A molding head includes: an outer casing unit that has a top wall portion which is installed above a discharge hole and in which a plurality of shaping holes are formed, and that causes a molding surface of the top wall portion to discharge the content which has passed through the shaping holes; and an inner plate that is disposed inside the outer casing unit and defines a dispersion chamber between the inner plate and a supply surface of the top wall portion, in which a guide protrusion portion with which the content collides to be introduced to openings of the shaping holes on the molding surface side is formed on at least one of inner surfaces of the plurality of shaping holes, or in at least one of circumferential opening edge portions of the plurality of shaping holes on the supply surface side.

When a cosmetic material is stored for several months, even in the case where hydrogen is contained in the cosmetic material at the beginning, hydrogen is gradually effervesced from the cosmetic material and after a certain time period has passed, the anti-oxidant effect cannot be maintained. Therefore, to solve this problem, a hydrogen-enriched cosmetic material container has hydrogen encapsulated in a bag formed of a hydrogen permeable sheet; then placing the hydrogen bag together with a liquid cosmetic material into a soft case formed of a flexible and hydrogen impermeable sheet, and then connecting a manually operable pump member for dispensing the liquid cosmetic material in the soft case through an opening of the soft case in an airtight manner.
