Definitions

• the present invention relates to an assembly for dispensing a pasty product or a gel.
• the assembly according to the invention is of the type comprising a pump without air intake.
• the container containing the product to be dispensed must be of variable volume, that is to say that its volume must be capable of decreasing as the product is dispensed.
• the variable-volume container can be a rigid container containing a follower piston which rises towards the pump as it is dispensed, or a container with a deformable wall of flexible plastic material, or folded in the form of an accordion .
• the pump is generally fixed by crimping the pump body on a crimping cup or a plate; the pump has a hollow emerging rod, which both activates the pump and lets the product out.
• the pump is actuated using a dispensing head by pushing in the emerging rod, the dispensing head containing dispensing channels opening outwards.
• This type of dispensing assembly is generally used for liquid or slightly viscous products and the product is sprayed from the dispensing head.
• an assembly is generally used where the product is in a container fitted with a follower piston and where the piston is pushed using a rotary mechanism to release the product.
• This system has several drawbacks: on the one hand, the product is not protected from ambient air during storage, because, although the container is closed by a lid, it is not waterproof so that, to protect the product during storage, it is necessary to put a protective film on the dispensing head, on the other hand, the application of the product requires two successive gestures: actuate the wheel and apply the product.
• the present invention relates to a dispenser assembly which makes it possible to use a pump for dispensing a relatively viscous fluid product, that is to say in the form of a paste and gel, and which has the advantage of requiring only one gesture for the distribution and application of the product.
• a variable volume container is used provided with a pump associated with a dispensing head which allows, in a single gesture, to actuate the pump and to carry out the application, the pressure exerted by the user on the dispensing head during application, for example when rubbing it on the skin, actuating the pump and causing the dispensing.
• the subject of the present invention is an assembly for the distribution of a viscous fluid product, in particular a paste or a gel, comprising a variable-volume container containing the product to be distributed, the distribution taking place by means of a pump without air intake.
• a pump body in free communication with the interior of the container and a product outlet member, said distribution being implemented by means of a distribution head comprising distribution channels, which open to the outside and are supplied by the pump outlet member, characterized in that the dispensing head comprises, firstly, a plate, which is provided with a means of assembly on the pump outlet member and an opening at right of said pump outlet member, and, secondly, an applicator element, which is, on the one hand, integral with the plate, on the other hand, disposed on the side of the plate where is not the container and, finally, provided with openings opening towards the outside, the distribution channels, which connect the pump outlet member to the openings of the applicator element being arranged between the plate and said applicator element.
• the pump is actuated simultaneously, since the applicator element and the plate are integral.
• the product leaves through the openings of the applicator element through the channels connecting the pump outlet member and the openings of the applicator element. According to the invention, therefore, the pressure exerted on the dispensing head is used during application to actuate the pump.
• the pump is a pump with an emerging rod, said rod being hollow to constitute the outlet member of the product and can be pushed towards the pump body to ensure the distribution of said product.
• the distribution channels can be provided in the plate or in the support, or also partially in the surface of the plate facing the applicator element and partially in the surface of the applicator element facing the plate, the surfaces of the plate and of the applicator element being complementary and forming the channels when they are placed one against the other.
• the different channels connecting the pump outlet to the different openings of the applicator element have variable sections, so as to obtain for each opening hole of the applicator element equal flow rates of product to be distributed according to the length of the different channels, that is to say as a function of the relative arrangement of the different openings and of the pump outlet.
• the plate is advantageously a generally flat or slightly curved plate. It is advantageously provided with an opening surrounded by a sleeve facing the container and intended for fixing the pump rod.
• the applicator element comprises a flat or slightly convex plate provided with regularly distributed openings. During use, the user rubs the applicator on the skin and, simultaneously, he activates the pump and distributes the product to be dispensed leaving through the openings in the plate.
• the applicator element comprises a cup whose bottom is provided with openings and on the side walls of which is fixed at least one roller; the axis of the roller is perpendicular to the axis of the container; the roller is provided with radial blades, the axis of the roller being arranged so that the edge of the radial blades rubs against the bottom of the cup and can take the product dispensed through the openings arranged in the bottom of the cup.
• the edge of the blades is preferably cut out regularly, for example in the form of a sinusoid.
• the applicator element comprises a support provided with cells in the form of a spherical cap in which balls are arranged, openings being formed in the support, at the bottom of the cells.
• the applicator element comprises a comb consisting of a base plate from which project outwardly teeth having the shape of prisms of triangular or trapezoidal cross section.
• the teeth are formed of prisms with an isosceles trapezoidal section, the edges of which are arranged in parallel.
• the openings can be arranged in the base plate between the teeth but preferably open in the side walls of the prisms forming the teeth.
• the plate-applicator element assembly constitutes the pump actuation system.
• this assembly is fixed on the pump rod and it is capable of linear translation when the user presses on the applicator element; the applicator element generally comprises a skirt capable of sliding on the side wall of the container.
• the pump used according to the invention can be any pump without air intake.
• a "soft" pump is used, which is actuated for a pressure of less than 1 kg / m 2 .
• the container containing the product to be dispensed is of variable volume, as explained above. It can consist of a bag with deformable walls, which deforms as the product is distributed or by a container folded in an accordion whose folds close. It is preferably constituted by a rigid envelope in which slides in leaktight manner a follower piston which approaches the pump as the product is dispensed. The bottom of the rigid envelope can be opened or it can be closed, an opening being then made to allow an air intake.
