Disclosed is the invention of a pump dispenser wherein a deformation prevention locking part induces a chaplet to move in the axial direction in a housing at the time of rotation of a head part, thereby allowing or restricting an operation of pressing a head part while preventing the deforming of an elastic member. The disclosed pump dispenser comprises: a cap part fastened to a container; a housing which is provided at the cap part and in which a content stored in the container remains in a dischargeable state; a shaft received in the housing so as to be movable in the axial direction, the shaft including a head part for discharging the content remaining in the housing to the outside through a pressing operation by an external force; a chaplet provided in the housing such that the shaft is inserted so as to be able to extend therethrough, the chaplet allowing or blocking the movement of the shaft on the basis of the angle of rotation of the head part; an elastic member provided on the circumference surface of the shaft and elastically supporting the chaplet and the head part; and a deformation prevention locking part for inducing the chaplet to move in the axial direction in the housing at the time of rotation of the head part, thereby allowing or restricting an operation of pressing the head part while preventing the deformation of the elastic member.

Solid low foaming and low pH all-purpose cleaning and disinfectant compositions are disclosed. The solid disinfectant compositions comprise approximately 50% w/w to approximately 75% w/w of citric acid encapsulated by a binder and approximately 1% to approximately 5.5% w/w of sodium benzoate. The solid cleaning and disinfectant compositions comprise approximately 50% w/w to approximately 75% w/w of citric acid encapsulated by a binder; approximately 1% to approximately 5.5% w/w of sodium benzoate; and approximately 10% w/w to approximately 15% w/w of sodium lauryl sulfate. The solid compositions are dissolved in water to produce a disinfectant solution comprising approximately 1.2% w/v to approximately 2% w/v citric acid and approximately 0.083% w/v to approximately 0.15% w/v sodium benzoate. A 10 minute contact time with the disinfectant solution provides a 5 log.sub.10 reduction in Staphylococcus aureus on a surface.

A full-plastic trigger spray pump, comprising a pump body (1). The lower part of the pump body (1) is connected to a locking cover (8); a liquid spray channel (11) is provided in the pump body (1); a nozzle (2) is provided at an outlet of the liquid spray channel (11); a liquid outlet channel (12) and a liquid inlet channel (13) which are vertically isolated from each other are provided in the pump body (1); the liquid outlet channel (12) is communicated with the liquid spray channel (11); a liquid guide chamber (14) is provided on a side of the liquid outlet channel (12) and the liquid inlet channel (13); the upper part of the liquid guide chamber (14) is always in communication with the liquid outlet channel (12) by means of a normally open port (15); a pumping piston (3) is provided in the liquid guide chamber (14); a trigger (4) capable of driving the pumping piston (3) to do piston movement in a left-right direction in the liquid guide chamber (14) is hinged onto the pump body (1); an elastic arm (5) capable of pressing against the pump body (1) and driving the trigger (4) to return the pumping piston (3) back is provided on the trigger (4); a lateral one-way valve that can be opened during the return movement of the pumping piston (3) so as to enable the liquid guide chamber (14) to be communicated with the liquid inlet channel (13) is provided between the liquid guide chamber (14) and the liquid inlet channel (13). The full-plastic trigger spray pump has simple structure and high liquid inflow efficiency, and can make full use of the solution pumped into the liquid guide chamber via a pump.

A method of using a fluid dispenser unit having a reservoir and a piston that slides in the reservoir. The unit includes an extractor head secured to the reservoir to suck fluid to be dispensed into the reservoir, and a spray head assembled on the extractor head to spray the fluid out from the reservoir. The method includes the steps of sucking a fluid to be dispensed into the reservoir through the extractor head; assembling the spray head on the extractor head; and spraying the fluid through the spray head. The step of sucking up a fluid to be dispensed includes a first step of extracting a fluid, such as a solvent, from an extraction reservoir, and a second step of mixing the fluid with a first substance, such as a powder or a lyophilisate, so as to form the fluid to be dispensed.

A dispensing nozzle and a dispensing assembly incorporating the dispensing nozzle are provided. The dispensing assembly comprises a cap body, a dispenser actuator, and a dispensing nozzle. The dispensing nozzle comprises a nozzle base having a mounting end configured to be mounted to the dispenser actuator; and a nozzle body connected, at a connection joint, to a distal end of the nozzle base. The connection joint includes a first surface having an arcuate slot and a second surface opposing the first surface, which may include a post, the arcuate slot being configured to receive the post. The post is configured to pass through the arcuate slot such that the nozzle body is configured to rotate about the nozzle base.

The present disclosure provides a method for the surface modification of microstructured components having a polar surface, in particular for high-pressure applications. According to the method, a microstructured component is contacted, in particular treated, with a modification reagent, wherein the surface properties of the component are modified by chemical and/or physical interaction of the component surface and of the modification reagent.

The invention relates to a dispensing device comprising a dispensing case that may house a dispensing cartridge, where the dispensing cartridge holds a liquid to be dispensed. The dispensing device further comprising a top cap, an actuator, a main body and a bottom cap, where the main body is positioned between the top cap and the bottom cap. The dispensing device further comprising top and bottom magnets that magnetically repel one another. Upon pressing of the actuator, material from the dispensing cartridge is dispensed and upon releasing of the actuator, the magnetic repellency of the top and bottom magnets moves the actuator back to its original position.
