The invention concerns an application tip for a device for applying and spreading a liquid, gel or paste product on a given surface configured to allow a volume of product to be transformed and spread over a surface according to a predetermined calibration (C) comprising, internally, a flow control means, —internally, at least one buffer volume, means for controlled dispersion of the product, and a device for applying and spreading a liquid, gel or paste product on a given surface comprising means for storing the product and an application tip according to the invention.

Tip and device for applying and spreading a liquid, gel or paste product

The invention relates to a device for ejecting a liquid or paste product, including a body () having a recess () for receiving a product to be ejected, characterized in that it includes a threaded rod (), which is translatably movable so as to act on the product to be ejected, a bolt (), which is mounted so as to engage with the threaded rod () in order to cause same to translatably move, and a lever () acting on the bolt () by means of a control means for causing the rotation thereof.

Ejection device for ejecting small doses

Method of manufacturing a device for ejecting a liquid or pasty product, characterized in that it comprises the following steps: drawing a product () to be ejected within a volume () of a container holder () of the ejection device by means of a pull rod (); removing the pull rod () from the container holder (); assembling a rear body () on the container holder () in order to form the ejection device.

Method of manufacturing a disposable ejection device

Device for ejecting a liquid or pasty product, comprising a body () that has a portion () designed to contain the product to be ejected and that has a hole () for ejecting the product, a rack () that moves in a bore () in the body () and causes the volume of the portion () designed to contain the product to vary, and a rack () movement mechanism comprising a pivoting lever () and a pawl () for acting on the rack (), which device is characterized in that the pawl () and the lever () form a one-piece plastics structure.

Disposable device for ejecting a liquid or pasty product

Device for difficult intervention in a closed enclosure, including a duct, a first end of which is intended to penetrate within the chamber, the duct being furthermore connected:

Simplified cleaning and filling device

A device for difficult intervention in a closed enclosure, having an enclosure connected to the closed enclosure via a duct, a piston that can be moved by a motor, a geometry allowing a contact with the outside air when the piston occupies a certain position within the enclosure in order to generate a sudden release of pressure, and an outlet valve remaining closed when the piston increases the volume of the enclosure so as to cause the pressure reduction within the enclosures.

Simplified cleaning and filling device with a piston

A cleaning device comprising an enclosure, a cover allowing it to be opened in order to place an object to be cleaned within the enclosure, a supply of cleaning fluid, the enclosure comprising a piston that can move thanks to a motor, a geometry allowing a contact with an external fluid reservoir when the piston occupies a certain position within the enclosure in order to generate a sudden release of pressure, the device comprising an outlet valve remaining closed when the piston increases the volume of the enclosure so as to cause the pressure reduction within the enclosures.
