Definitions

  • the present invention relates to a fluid dispenser member generally intended to be associated with a fluid reservoir to form together a fluid dispenser. It is a dispensing member whose actuation is usually performed manually using a finger of the user.
  • the fluid product is distributed in the form of a jet of fine sprayed droplets, a continuous net or a dab of fluid, particularly in the case of viscous product, such as cosmetic creams.
  • Such a fluid dispenser member may in particular be used in the fields of perfumery, cosmetics or even pharmacy to dispense more or less viscous products.
  • the present invention is more particularly, but not exclusively, concerned with a type of dispensing member which is commonly referred to as a "push-pump".
  • a type of dispensing member which is commonly referred to as a "push-pump".
  • the dispensing member comprises a pusher forming not only a dispensing orifice but also defining a portion of a fluid product chamber in which fluid is selectively pressurized.
  • a pump it is a pump chamber.
  • a peculiarity of this pusher pump lies in the fact that an inner surface of the pusher, of generally cylindrical general shape, serves as a sealed sliding shaft for a piston which moves in sealed contact in this barrel to thus selectively unmask the orifice of distribution.
  • This piston is generally a piston of the differential type that moves in response to a pressure variation of the fluid within the chamber.
  • This differential piston is to be differentiated from the main piston whose displacement is generated by the actuation of the pusher.
  • a differential piston and a main piston movable in sealing contact in respective drums.
  • the main drum for the main piston can also be formed by the pusher.
  • the pusher comprises a bearing wall on which is exerted a pressure with a finger to actuate the pusher.
  • the pusher comprises a skirt that extends downwardly from the support wall. This skirt forms a first sealed sliding shaft for a differential piston and a second main shaft for the main piston of the pump.
  • the differential piston is dissociated from the main piston.
  • the differential piston is biased away from the support wall by a spring which acts as both a return spring and a precompression spring.
  • the sliding piston of the differential piston is formed with an outlet conduit which leads to a nozzle attached in a housing formed in the skirt of the pusher.
  • This nozzle forms a dispensing orifice at which the fluid product exits the dispensing member.
  • the housing formed by the skirt is made with a swirl system that cooperates with the nozzle to drive the fluid in a swirling motion before exiting through the dispensing orifice.
  • the present invention is therefore mainly, but not exclusively, concerned with this type of dispensing member more commonly known as a "push pump”.
  • the present invention is more particularly, but not exclusively, concerned with push-button dispensing members used as a sample.
  • the dispenser member of small size and small capacity is mounted on a reservoir of small size, commonly referred to as a "bottle”.
  • This bottle is usually made of drawn glass, but can also be made of plastic or metal.
  • perfume samples are often in the form of a glass bottle provided with a stopper.
  • This cap can be made in two parts, namely a base portion fixedly mounted on the bottle at its opening, and a sealing portion that can be mounted sealingly, but removable on the base portion .
  • this sample comprises a reservoir portion, a base portion and a capping portion.
  • the base portion provides the interface or junction between the capping portion and the reservoir portion.
  • the base portion and the plug portion are made of inexpensive plastic materials, which are generally translucent or transparent. It can therefore be seen through the base portion and / or the capping portion.
  • the object of the present invention is to provide a fluid dispenser member, and more generally a fluid dispenser, which generally has the general appearance of a conventional plug formed of a base portion and a part of corking.
  • the present invention proposes a fluid product dispensing member intended to be associated with a fluid reservoir having a neck, said member comprising a body at least partially delimiting a fluid product chamber, said body being provided with means fastening device on the neck of the reservoir, said body comprising a fluid product inlet connecting the inside of the reservoir to the fluid product chamber, a pusher mounted on the body axially displaceable between a rest position and a depressed position, and a spring urging the pusher in the rest position, characterized in that the spring is fully housed inside the pusher, and the body is made of transparent or translucent material.
  • the pusher visually functions as a closure member while the body visually functions as a base portion attached to the reservoir or the bottle.
  • the spring is not visible to the user.
  • the transparent or translucent plastic body it is visually closer to the conventional base portion of a conventional plug.
  • the spring is the most easily visible component of the dispensing member, since it is conventionally made of steel. This is why it is important in the context of the present invention to hide it inside the pusher, which can be made of an opaque plastic material, white or colored.
  • the purpose of housing the spring inside the pusher is to hide all the visible constituent elements of the pump inside an opaque element.
  • the pusher comprises a lateral skirt engaged around an inner guide bushing formed by the body.
  • the skirt and the bushing comprise complementary abutment means defining the rest position. The pusher is thus movable axially around a part of the body.
  • the fastening means are made integrally with the body, and are intended to advantageously engage around the neck.
  • the dispensing member further comprises a piston member movable axially inside the pusher, the spring biasing the piston member and the pusher in the rest position.
  • the spring bears on the one hand on the body and on the other hand on the piston element.
  • the piston member forms an inlet valve movable member adapted to come into sealing engagement with an inlet valve seat formed by the body.
  • the piston member is fully housed inside the pusher. This eliminates the use of a steel ball as a movable member of the inlet valve. Indeed, it could be apparent through the transparent or translucent body, which would be detrimental to the aesthetics of the distribution member, and thus to the distributor as a whole.
  • the dispensing member of the invention is generally or generally in the form of a conventional plug formed of a base portion and a capping portion. Therefore, the dispenser member may be integrated into a product line composed of both plugs and dispensing members.
  • the present invention also defines a fluid dispenser comprising a fluid reservoir and a dispensing member as described above.
  • the body is in sealed contact with the neck of the reservoir.
  • the seal which is generally made from an elastomeric material, is opaque, and thus visible through the body and / or the reservoir.
  • the reservoir, the body and the pusher have an identical maximum outside diameter, so that the distributor has a global cylindrical, advantageously circular.
  • This tubular aspect is further reinforced when the body fastening means are arranged around the tank neck and when the pusher extends around the body.
  • the dispensing member of the invention is intended to be mounted or associated with a fluid reservoir 2 having an opening in the form of a neck 21.
  • This neck 21 may form an external peripheral thickening so as to define a lower shoulder which will serve for hooking or fixing the dispenser member on the reservoir.
  • the reservoir conventionally comprises a reservoir body closed below by a bottom and defining in its upper part the neck 21.
  • the body of the reservoir may have a cylindrical shape over at least a part of its height, and preferably on any his height.
  • the section of the cylindrical portion may advantageously be circular so that the reservoir has a generally circular cylindrical tubular configuration.
  • the particular shape of the reservoir is not limiting for the present invention, which more particularly relates to the dispenser member.
  • the neck 21 may be devoid of lower shoulder.
  • the attachment of the dispenser member may also be made inside the neck.
  • the dispenser member in both embodiments of the figures, is a pump of the precompression type. It is more particularly a pump type "push-pump" in the sense defined above.
  • the present invention is applicable to other types of pumps that are not push pumps.
  • the dispensing member or pump comprises the following constituent elements, namely a body 1, a pusher 3, a piston member 4 and a spring 5.
  • these digital references are awarded.
  • the body 1, is preferably made of molded injected plastic material.
  • the plastic material used is transparent or at least translucent so that one can see through the body.
  • These fastening means 11 comprise an outer peripheral skirt intended to extend around the neck 21.
  • the skirt forms one or more internal fastening profile (s) 111 intended (s) to come in engagement under the shoulder formed by the thickened portion of the neck 21.
  • the introduction of the skirt 11 on the neck can be made by snapping into force, and the final fixing is achieved by snapping under the shoulder of the neck.
  • a vent passage 112 may be provided as shown in FIG. figure 1 , to allow the outside air to enter the tank as fluid is removed by the dispensing member.
  • the skirt can also be engaged in the collar.
  • the skirt 11 may have a substantially cylindrical outer wall whose outer diameter is substantially equal to that of the body of the reservoir, so that the skirt 11 extends in alignment with the reservoir, as can be seen in the figures.
  • the skirt 11 thus contributes to attenuating or masking the constriction achieved by the collar 21.
  • the body 1, the is fixed through the skirt 11 on the collar sealingly.
  • the seal can be achieved using a neck seal 113 which is crushed on the upper edge of the neck, as on the figure 1 . More specifically, the body forms an annular plate 12 which compresses the seal 113 when the profiles 111 of the skirt 11 are engaged under the shoulder of the neck 21.
  • the skirt 11 extends downwards from the outer periphery of the 12.
  • a sealing sleeve 18 which comes into sealing contact with the inner wall of the neck 21.
  • This second embodiment is preferred because it avoids the use of a seal, which is usually made of an opaque material, so visible. Indeed, in the second embodiment, the body is directly attached to the neck 21 without the use of any additional part, so that the user realizes directly that the body is attached to the neck, since the body is made of a transparent or translucent plastic material.
  • the body 1, 1 ' also forms a dip tube 14 which extends from the plate 12 inside the tank 2.
  • the dip tube 14 and the sealing sleeve 18 are the only elements of the body, and even of the dispensing member to penetrate inside the neck of the tank.

  • the plunger tube 14 extends downwardly from the plate 12, while that the inlet duct 17 extends upwards from the same plate 12.
  • the seat 13 of the inlet valve is formed by a peripheral bead which projects radially inwards. This seat 13 cooperates with a movable member of inlet valve 6 'which will be detailed below.
  • the body 1 also forms a ring 15 which extends upwards from the plate 12.
  • This ring 15 defines at its free upper end a main piston lip 16.
  • the body 1 defines a duct d 17 which is partially castellated and which extends from the tray 12 just in the extension of the seat 13.

  • This pump chamber 10 is defined between the ring 15 and the inlet duct 17, through the passage 44 and a space defined between the surface upper piston differential 41 and the lower surface of the bearing wall 31.
  • the piston member 4 ' forms the movable valve member 6' which cooperates sealingly and selectively with the inlet valve seat 13.
  • the spring 5 biasses the piston element 4' towards the bearing wall 31.
  • the spring 5 ' is supported on the one hand on a shoulder of the bushing 19 and on the other hand under the differential piston 41. This corresponds to the rest position of the figure 2a .
  • the passage between the pump chamber 10 and the dispensing orifice 341 is prevented by a sealed contact formed between the differential piston 41 and the support wall 31.
  • the main piston 41 slides in the barrel 15 by compressing the spring 5 '. This has the effect of moving the piston member 4 'away from the bearing surface 31 by compressing the spring even further.
  • a passage is created between the pump chamber 10 and the dispensing orifice 341, so that the fluid under pressure can escape.
  • the spring 5, 5 ' is fully housed or inscribed inside the pusher 3, 3'.
  • the pusher is preferably made of an opaque plastic material or colored, so that the spring is not visible inside the pusher. This is an interesting feature of the invention, since the user can not see the spring, even with the body made of transparent or translucent material.
  • the piston member 4 ' is also fully housed or inscribed within the pusher 3'. Thus, it is not visible to the user. Therefore, the dispensing member has the appearance of a conventional plug, and not a pump. The user sees that the dispenser member consists solely of two parts, in this case the body transparent or translucent and the pusher, that it can appear to a part of conventional capping.
  • the distributor constituted by a reservoir and a dispensing member according to the invention has a cylindrical circular cylindrical general appearance.
  • the type of pump in this case a "push-pump", should not be considered as the only type of pump capable of implementing the present invention.
  • the pusher pump is advantageous because it allows to house certain elements of the pump inside a single element, in this case the pusher.
  • the body can be transparent, further increasing the appearance of a simple plug.
