Tottle for containing and dispensing fluid, including a container endowed with first sealed end and second end featuring a neck, hermetic pump whose body is at least partially housed inside the neck, the pump coupled with the neck of the container by a collar, the pump coupled to a gasket, made as a single piece and including a first lip positioned in contact, in a sealed manner, with the pump body and shaped to fit onto the pump body by interference, and a second lip from which a sealing flange extends, and an intermediate portion which interconnects the first and second lips to form an annular groove facing a flange on the pump, so when the collar is fastened to the neck of the container, the sealing flange on the gasket is between the flange on the pump and a free edge of the container neck.

The invention proposes a foam dispensing system for a dispenser comprising a reservoir storing cosmetic product, said system comprising a product pump and an air pump, said product pump comprising a variable volume product metering chamber (13) defined at least partly by a deformable element (2), said system comprising at least five valves referred to as a product inlet valve for the product to enter toward the product metering chamber (13), a product outlet valve for the product to exit from the product metering chamber (13), an air inlet valve for the air to enter in an air metering chamber (14) of the air pump, an air outlet valve for the air to exit from the air metering chamber (14), an air return valve for the recovery of the air of the reservoir. The deformable element (2) comprises at least four flaps which are movable between a valve open state and a valve closed state.

A container having a pressurized chamber containing a fluidic material and a dispensing assembly coupled thereto. The dispensing assembly includes a dispensing passageway for discharging the fluidic material from the container. A dispensing valve, a tilt valve, and a pump assembly are all operably coupled to the dispensing passageway. The tilt valve is alterable between a closed state in which the pressurized chamber is scaled and an open state in which the dispensing passageway is fluidly coupled to the pressurized chamber. The pump assembly is alterable between a first state in which a variable volume of the dispensing passageway in at a first volume and a second state in which the variable volume is at a second volume that is less than the first volume. Thus, the pump assembly creates a negative pressure behind the dispensing valve to prevent excess fluidic material from being dispensed.

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.

Embodiments include a bottle and method for cleaning a grill. An exemplary method may be applied to grills having an upper grill and a lower grill. Methods can include providing a bottle having a dosing chamber with a first outlet, a reservoir chamber configured to store a solution and including a second outlet, and a sprayer for dispensing solution via the second outlet. The sprayer includes a spray head and a trigger that, when actuated, draws solution from the reservoir chamber and dispenses it by spraying the solution from the spray head. Methods can include filing the dosing chamber with a predetermined dose of solution from the reservoir chamber and dispensing the solution onto the lower grill from the first outlet, and dispensing the solution onto the upper grill by spraying the solution onto the upper grill from the second outlet.

A new all-plastic micro miniaturized spray gun. Inner hole of miniaturized spray gun piston bush includes lower elastic sleeve; upper and lower ends of piston cavity in inlet hole of body include upper and lower thru-hole; upper elastic sleeve disposed above inner hole of piston bush in inlet hole on body between upper and lower thru-hole; upper elastic sleeve abutted against piston bush and fixed in inlet hole of body; diversion groove is disposed on inner walls of inlet hole on body; which is tapered and corresponds to upper elastic sleeve; which includes piston and cover; lower thru-hole of body is normally open; when upper thru-hole of body drives piston to move inwardly through wrench, lower elastic sleeve is stressed subject to pressure change, controlling opening or closure of inlet hole on body, and upper elastic sleeve is deformed subject to pressure change, opening or closing upper thru-hole of body.

Disclosed herein are various embodiments of a pump mechanism comprising a rigid structure having an open end and a closed end, a plunger disposed in the open end of the rigid structure, and a flexible, fluid-proof sheet of material attached to an inner wall of the rigid structure and bonded to the head of the plunger such as to form a fluid barrier between the interior of the rigid structure and the plunger. Movement of the plunger toward the closed end of the rigid structure causes a rolling corner to be formed between the head of the plunger and the rigid structure and a fluid contained within the pump chamber to be forced out of the pump chamber via a fluid port defined in the closed end of the rigid structure.

A trigger sprayer having a venting system including a piston bore and a vent bore at least partially contained therein, the vent bore including at least one vent port; a piston and vent piston are moveably seated in the piston bore and vent bore, respectfully, the vent piston including at least one annular seal and a vent path port, the vent path port and vent port in gaseous communication when the vent piston is actuated and moved over the vent port.

A hair-penetrating multi-point spraying apparatus for animals with thick fur according to an embodiment of the present invention comprises: a fluid storage part for storing a fluid; a nozzle part provided so as to spray the fluid in close proximity to the skin of an animal with thick fur by means of a plurality of nozzles; and a spraying tool part for supplying the fluid in the fluid storage part to the nozzle part by pumping, The nozzle part has: a plurality of comb teeth for brushing the fur of an animal with thick fur; and a plurality of comb-teeth end nozzles protruding in the form of comb teeth so as to spray a fluid on the skin beneath the fur of the animal with thick fur.

Proposed is a cosmetic container cap with a duo-mix function, including a body part in which a female fastening portion is formed below a chamber where an accommodation space is formed to accommodate a first cosmetic content of liquid or powder so as to be fastened to a male fastening portion, and having a hollow dip tube formed to extend downward from the chamber, a pumping member coupled to the chamber to press down the first cosmetic content toward the container to be mixed with a second cosmetic content inside the container, and configured to pump a cosmetic mixture in which the first cosmetic content and the second cosmetic content are mixed into the dip tube and the chamber to be discharged outside, and a dip tube sealing means for closing and opening the dip tube so that the first cosmetic content and the second cosmetic content are mixed.
