Definitions

  • the invention relates to a dispensing head for a consistency product.
  • viscous liquid comprising a rigid capsule and an elastic member for closure provided with at least one closed distribution slot, capable of opening under the thrust of the product and to return to an initial position, when this thrust.
  • the invention also relates to a product distribution assembly equipped with this dispensing head, as well as a process for manufacturing this last.
  • the invention relates to a distribution set of the kind of those which include a semi-rigid or flexible tank fitted with a dispensing head rigid or semi-rigid, provided with an elastically dispensing orifice deformable.
  • the distribution assembly of the invention is intended, more particularly, to equip a compressible tank containing the product and allow its distribution in good conditions of cleanliness.
  • This product can be, in particular, a cosmetic, dermatological or food product, such as by example a shampoo, a styling gel, a foaming shower gel, a liquid soap, face cream, body lotion, liquid eyeshadow, or household product or glue.
  • a tube of liquid product equipped a distribution head has a rigid capsule provided with a product outlet orifice in the form of an elastic membrane reported, in which is made, by mechanical cutting, a slot.
  • a fixing ring holds the membrane on the dispensing head.
  • this tube has drawbacks from the point of view of its manufacturing. Indeed, the assembly of the head into two or three separate parts (capsule, membrane, fixing ring of the latter), requires the use of a special assembly machine increasing the manufacturing price. In addition, the production of the slit is carried out, in particular, by cutting requiring the recovery of the membrane in another machine, which further increases considerably the cost price of the dispensing head of the prior art.
  • a dispensing head comprising a circular membrane split with a peripheral fixing sleeve folded into a "U" shape.
  • the edges of the slot are obtained by mechanical cutting of the slot. Consequently, this distribution head is expensive and economically disadvantageous. For for this reason, it is not suitable, in particular, for a widely distributed product, like a shampoo or dishwashing detergent, for which the sale price must be moderate.
  • the elastic closure has a slot formed by two parallel lips, located in particular projecting from the outer face of the elastic member, so that a recess is formed on the inner face of the organ, in a area near the edges of the lips.
  • the object of the present invention is to provide a distribution assembly for simple to manufacture and extremely cost-effective.
  • the Applicant has discovered that one and the same can be carried out machine, on the one hand the injection of the capsule and the elastic member, and on the other hand apart from making a slot with contiguous edges therein.
  • the distribution slot of the elastic member is not obtained by mechanical cutting, but by knocking down using a suitable tool of a thinner area, for example mechanically or pneumatically.
  • This knockout can be, in particular a pressure exerted on one side or the other of the elastic member on the area of reduced thickness.
  • the present invention relates to a product dispensing head of liquid viscous consistency, comprising a rigid or semi-rigid capsule and an elastic closure member secured to the capsule.
  • the dispensing head is characterized in that a smaller area thickness is delimited by the edges of a groove made in the organ elastic, the thinner zone being able to rupture under the effect of pressure exerted on one side or the other of the elastic member so defining at least one contiguous slot capable of opening under the thrust of the product for distribution, and return to the joined position when this thrust.
  • the elastic closure member is in the form a more or less thick membrane, placed at the end of a channel supply in the capsule and in communication with a reservoir containing the product to be distributed.
  • the capsule is formed from a first thermoplastic material rigid or semi-rigid, for example polyethylene or polypropylene.
  • This capsule is fixed, for example by screwing or snapping, on the reservoir product to distribute.
  • this bottle is semi-rigid or flexible, provided of compressible walls, so that a pressure on the walls of the bottle triggers the distribution of the product.
  • the capsule is provided a distribution channel closed by the elastic member.
  • the slot is made by knocking out of the membrane.
  • the throat constituting a zone of pre-weakening, for example in the form of a veil, can be opened by knocking, or mechanically using an appropriate tool, either pneumatically, using a jet of compressed air.
  • the slot may be surrounded, continuously or discontinuously, by a bead or reinforcement godron.
  • the knockout of the thinner area can be carried out, in particular, either on the internal side or on the external side of the membrane.
  • the slot thus formed constitutes a dispensing orifice, substantially sealed to the untimely flow of the product.
  • the edges of this slot deviate from one of the other, when the user exerts pressure on the inverted bottle, head in low, to cause the distribution of a dose of product. Thanks to the elasticity of the membrane, the slit returns to its original shape, when the pressure on the bottle, and the flow of the product stops completely.
  • this elastic member is a membrane made of a second material elastomeric, and more particularly in thermoplastic elastomer. More precisely, this membrane is formed by a flexible material, having a shape memory capable of resuming, after deformation, its initial shape.
  • this material is chosen so that the membrane can be molded in a single piece with the capsule, for example by biinjection first and second materials.
  • a second material we choose an elastomer that is physically and chemically compatible with the first material of the capsule and capable of forming a bond with it solid, by thermofusion.
  • the membrane is constituted, by example, by blends of polypropylene and block copolymers styrene - butadiene - styrene, polypropylene and block copolymers styrene - ethylene - butylene - styrene, polypropylene and copolymers of block of ethylene - propylene - diene.
  • the membrane is in the form of a washer of variable thickness. It is however possible to carry it out in any other desirable shape, for example oval.
  • the surface of this washer can be flat, but advantageously, this surface is curved, for example concave or convex. More particularly, a convex membrane is preferred whose convexity is turned to the side where the product push is exerted.
  • the slit in the membrane preferably passes through the center of the washer. According to the invention, this slot is located at the bottom of a groove formed in the membrane.
  • This throat straight or curvilinear, presents advantageously a “V” or “U” section. It can be done in several branches. Two or more grooves can be made. These gorges can be parallel or crossed.
  • the membrane has two grooves crossed, forming a right angle between them.
  • the depth of this gorge advantageously represents 30% to 90% of the total thickness of the membrane.
  • the total thickness of the membrane is located between 0.5 mm and 3 mm.
  • such a groove has a length from about 0.5 cm to 2.5 cm.
  • the bottom of the throat is formed by an area of lesser thickness in the form of a thick veil from about 0.1 mm to 1 mm.
  • the capsule may further include a hinged cover capable of being placed on the elastic member and intended to ensure the protection of the membrane during product storage.
  • this cover is articulated with the capsule, preferably, using a film hinge. This allows molding integral in a single piece of the dispensing head (capsule - hinge - cover - membrane with slot).
  • the inside of the cover may include one or more sealing means, capable of coming to bear on the elastic organ.
  • its internal face may include an annular bead, able to surround the slot and press tightly against the membrane.
  • a distribution assembly provided with a product reservoir and comprising the head dispenser according to the invention can be used, in particular, for the distribution of a liquid viscous consistency product.
  • the viscosity of this product is typically in the range of 0.8 Pa ⁇ s to 10 Pa ⁇ s, and more particularly in the range from 1.2 Pa ⁇ s to 8 Pas.
