Definitions

• the present invention relates to a set of application of disintegrating product comprising a rigid protective envelope, the product being capable of sliding in this envelope between two positions: a retracted position where the product is protected inside the envelope , and an extended position where the product can be applied to a surface to be treated.
• This application set is intended, more particularly, to distribute and apply a cosmetic, dermatological or food product, such as for example a stick (or stick) of deodorant or depilatory, a gel, a cream, a make-up bread, a stick of lip product or blush, a blush, a foundation, or a stick of glue.

By fixing the product on the spring, this product is suspended, in a way, in an elastic manner.
• the present invention aims to avoid all the drawbacks of this prior applicator, by making available to the consumer an applicator of disintegrating product, of gentle application, the operation of which is an.
• the invention thanks to an improved elastic suspension of the product, it can be applied gently to the surfaces to be treated, for example sensitive areas of the skin, such as the lips or the armpits, the gentle application being constant from the start of the application of the product until the end of its consumption.
• the present invention has for first goal a set of improved functioning application of very soft application, usable in particular for a hard and not very crumbly product, ensuring a regular disintegration.
• Another object of the invention is to avoid drying of the product, by associating with this applicator a closure element.
• the product application surface is in permanent elastic contact with this closure element, making it possible to reduce as much as possible the evaporation of volatile compounds which may be present, if necessary, in the product.
• the present invention relates to an application assembly for a delitable product of viscous to solid consistency, for example in the form of solid bread, cream or gel, having an application surface
• this application assembly comprising : a) an envelope open at one of its ends, the end of the envelope opposite the open end having a bottom, b) a support on which the product is mounted, said support being axially movable at the inside the envelope, c) drive means capable of adjusting the height of the support inside the envelope, d) actuation means accessible from the bottom of the envelope for controlling said means of drive, and e) elastic means, axially deformable, to allow, under the effect of a pressure exerted on the application surface, substantially axially, a relative axial displacement between the product and the envelope meeting d 'a forced e of recall exerted by the elastic means.
• said drive means are distinct from elastic means.
• the elastic restoring force is substantially constant, whatever the position of the support inside the envelope, which contributes to providing a softness of constant application over use.

• the elastic spring is crossed by the rod.
• the elastic means may also consist of a block of elastically compressible cellular foam, or be in the form of one or more spring blades which are elastically flexible, or else have a structure of the elastically deformable bellows type. This bellows can be an integral part of the external envelope and be arranged between said envelope and the bottom. In this configuration, the bellows is elastically stretchable.

• the end of the rod, emerging from the bottom towards the outside of the envelope, is integral with the actuation means, accessible to the user.

• the rod, the wheel, the support and the product bar form an assembly, capable of sliding axially in the envelope, when pressure is exerted on the surface of application of the product bar, by applying it on a object to be processed.
• This pressure causes an elastic retraction of the product roll, as well as of the support and of the rod, by compressing the spring. So a product loaf can be gently applied to a surface, which is particularly suitable for applying a solid, disintegrating product to sensitive areas of the skin.
• the operating member is a push button, which the user can push in by axial pressure.

Pressure on the application surface of the product roll is therefore transmitted, via the support and the rod, to the bottom and the narrow zone of the envelope. Consequently, the bottom then moves back a determined distance, stretching the elastic bellows.
• the product is of solid and crumbly consistency, such as a deodorant stick or a lipstick grape.
