Diffuser and device for packaging and dispensing a foaming product
First Claim
1. A diffuser for a device for packaging and dispensing a foaming product, comprising;
- a collar mounted above a container, said collar having a longitudinal axis;
a product diffusion head extending from the collar and including at least one output aperture through which the foaming product exits the device; and
a beveled surface mounted above the collar that increases in area from a front side of the diffusion head including the output aperture to a back side thereof,wherein the diffusion head is movable relative to the collar such that, at each position of the diffusion head, an axis of the output aperture is oriented downward towards a bottom of the container at an angular sector within a range from 0 to 85 degrees from a direction parallel to the longitudinal axis of the collar, andwherein said diffusion head is movable relative to the collar such that the diffusion head is contained within a maximum cross-section of the collar and/or of the container as measured orthogonal to the longitudinal axis of the collar.

Abstract
A diffuser for a device for packaging and dispensing a product. The arrangement is particularly advantageous for foaming cosmetic products. The diffuser includes a collar which can be mounted on a container and a product diffusion head extending from the collar and provided with at least one output aperture. Preferably, the output aperture is oriented at an angle, relative to an axis of the collar, lying between 0° and 85°. The diffusion head is movable relative to the collar. Moreover, the diffusion head has an extension axis inclined with respect to a longitudinal axis of the collar, and has a size which is contained within the maximum cross-section of the collar and/or of the container.

21. A diffuser and container assembly, comprising:
-
a container containing a product, said container having an outer diameter; a diffuser mounted on said container, the diffuser comprising; a collar coupled to the container, the collar including; a first tubular portion concentric to the container and having a first annular radially-outwardly-facing surface, a second tubular portion concentric to the container and having a second annular radially-outwardly-facing surface, a diameter of the second annular-radially-outwardly-facing surface smaller than the first annular-radially-outwardly-facing surface, and a radial abutment surface between the first tubular portion and the second tubular portion, the radial abutment surface configured to interface with a cap, the cap configured to cover a diffusion head; and the diffusion head extending from the collar, said diffusion head including; a base, and an output aperture arranged such that when said container is in a vertical position a flow of the product exiting said output aperture is directed in a downwards direction, the diffusion head being connected by a hinge to the second tubular portion, wherein said diffusion head is movable relative to the collar such that, at each position of the diffusion head, an axis of the output aperture is oriented downwards towards a bottom of the container at an angular sector within a range from 0 to 85 degrees from a direction parallel to a longitudinal axis of the collar, and wherein the base includes a beveled surface mounted above the collar that increases in area from a front side of the diffusion head including the output aperture to a back side thereof. - View Dependent Claims (22, 23, 24, 25, 27, 29)
