Problems solved by technology

This may risk losing the seal, requiring precise dimensioning of the ball and the channel in which it is stuck
In addition, plastic spheres are ground, so there is a risk of metal particles from the sphere grinder

Embodiment Construction

[0018] The invention relates in particular to a device of the type proposed in document WO 02 / 45866. This document deals with the general operation of the device.

[0019] However, it is obvious that the invention is not limited to this type of device, but instead applies to all types of dispensing devices for fluid and powdery products, which have a container, which is closed by a closure, the contents of which should be expelled by an air flow .

[0020] The drawing shows a preferred embodiment of the invention. The device has a container 30 with an air inlet 31 and a product outlet 32 ​​. The air inlet 31 of the container is connected to the exhaust 20 and the product outlet 32 ​​of the container is connected to the dispensing outlet 10 of the device. The product outlet 32 ​​is closed by a closure 50 which is a tight fit in said product outlet 32 ​​. The air inlet 31 is provided with a product retaining mechanism 40 adapted to retain the product in the container prior t...

Abstract

A dispenser device for dispensing a fluid or powder composition, including a dispenser outlet, an air expeller, and a reservoir containing a dose of a composition. The reservoir includes an air inlet connected to the air expeller, and a composition outlet connected to the dispenser outlet. The air inlet includes a composition retainer member for retaining the composition in the reservoir until the composition is dispensed, and the composition outlet being closed by a closure element that is force fitted in the composition outlet of the reservoir. The device includes a mechanical opening system that co-operates with the closure element so as to expel it mechanically from its closed position while the device is actuated. The closure element is an element that is not spherical, including a rounded portion, in particular a hemi-spherical portion, that faces towards the inside of the reservoir in the closed position.

Description

technical field [0001] The present invention relates to a dispensing device for a fluid or powder product, in particular a device for unitary dispensing of a dose of product contained in a container by means of a pressurized air flow. Background technique [0002] Document WO 99 / 46055 proposes such a device in which a spherical closure closing the outlet of the container is driven by an air flow generated by an exhaust. In order to use especially powdered product dispensing devices, the air pressure required to actuate the device must be high enough to ensure that the dose is dispensed completely and, if necessary, divided into portions. In the above devices, the air pressure required to activate the device depends on the resistance given by the ball being driven. This resistance is difficult to control and difficult to predetermine, since it depends on the friction between the sphere and its cylindrical seat, in which the sphere fits tightly, hermetically closing the conta...
