Definitions

  • the subject of the present invention is a device for packaging and dispensing a fluid composition by means of a pipette.
  • the invention is used more particularly in the field of devices for packaging cosmetic products, in which the product has to be delivered in the form of doses.
  • cosmetic product is understood to mean any product as defined in Regulation (EC) No 1223/2009 of the European Parliament and Council of 30 November 2009 relating to cosmetic products.
  • EP0248345 discloses a packaging and application device having a container and a closure member, the closure member being equipped with a pipette for withdrawing a dose of product.
  • This device teaches pulling on a piston located in the pipette in order to fill the latter with a dose of product, and, in a second stage, unscrewing the closure member so as to allow this dose to be dispensed by pushing the piston.
  • the user of such a device is faced with the problem of having to carry out a number of successive manipulations, firstly pulling on the piston, then unscrewing and then applying pressure to the piston.
  • this device has a first cap to remove, with a piston of the pipette then being pulled on in order to fill the latter, before finally the pipette is unscrewed in order to apply a dose.
  • a packaging and dispensing device that makes it possible, with one and the same hand movement, both to detach the closure member in relation to the container and to fill a tubular portion firmly attached to the closure member is known from the teaching of document FR2924696.
  • the product is retained in this tubular portion by capillary action.
  • This type of device is also problematic inasmuch as it does not allow tiny quantities of product to be filled, and it is necessary to return the closure member to its completely closed position in order to refill the tubular portion.
  • this device also only allows tiny doses to be dispensed by capillary action with the substrate on which they will be deposited.
  • Document FR2549015 describes a packaging and dispensing device having a container and a closure member equipped with a pipette and a pumping mechanism via a push button.
  • This device teaches pressing on the push button and then releasing it in order to suck up a dose of product when the push button returns to its position under the effect of an elastic member, and, in a second stage, unscrewing the closure member in order to allow this dose to be applied.
  • the user of such a device is faced with the problem of having to carry out multiple successive manipulations, firstly applying pressure to the push button in order to withdraw a dose and then unscrewing prior to application.
  • Document FR2964953 describes a packaging and application device having a container and a closure member equipped with a pipette and a pumping mechanism via a push button.
  • the mechanism is complex and makes use of numerous elements in order that the action of screwing and unscrewing the closure member respectively brings about the expulsion and sucking up of a dose of product into the pipette.
  • document FR2968516 describes a mechanism for a cosmetic product applicator that allows simple hand movements. However, this document does not describe a dispensing pipette.
  • the object of the present invention is thus to provide an improved device for packaging a cosmetic product in order to alleviate the abovementioned drawbacks.
  • the invention proposes a packaging and dispensing device having a container intended to contain a fluid product, and a closure member for closing the container, the closure member having:
  • a dispensing pipette designed to be inserted into the container and connected to a pump body so that at least one dose of product contained in the container can be withdrawn and dispensed
  • the pump body formed by a tubular jacket having protuberances, - a push button connected to a piston mounted in a sliding manner in the pump body such that the dose of product contained in the pipette can be sucked up or expelled,
  • the pump body is mounted in a sliding manner with respect to the cap and each of the protuberances is engaged in a cavity in the insert, the protuberances in particular abutting against the lower edges of the cavities.
  • the invention advantageously provides a packaging device having simple hand movements since the user does not have to carry out excessive multiple manipulations: simply opening the packaging device gives him access to a pipette already filled with product.
  • this device ensures that the container is impermeable up to the moment at which the user manually withdraws the pipette from the container, thereby limiting leakage resulting from accidental opening of the container.
  • the closure member may be designed to suck up a dose of product as this closure member passes from a closed position to an unlocked position of the container.
  • the retaining means may be a thread connected to the cap and engaging with a complementary thread on the container.
  • the retaining means may be a catching portion connected to the cap and engaging with a retaining element fixed to the container, an actuating means making it possible to release the retaining element from the catching portion.
  • the cap may move in a purely translational movement from its locked position to its unlocked position, in which it can be freely separated from the container.
  • the pipette may remain fixed with respect to the container as the cap passes from the locked position to the unlocked position.
  • the container may have an opening provided with a sealing member that comes into radial contact with a portion of the pipette and/or the pump body when said pipette is inserted into the container.
  • the cap may have a first stop that engages with the push button when said push button is in a high position, and a second stop that engages with the pump body when said pump body is in a low position.
  • the cap may have a fixed insert having the catching portion, the first stop and the second stop.
  • the portion of the container with which the closure member is engaged may have a non-circular section.
  • the retaining means may have a band fixed to the container and an elastic return means.
  • the pipette may be provided with an applicator end piece.
  • the device may contain a cosmetic product.
  • FIG. 1 shows an example of a packaging and dispensing device according to the invention
  • figure 2 shows an exploded view of the device from figure 1 ;
  • FIG. 3 to 6 show quarter longitudinal sectional views of the device from figure 1 , in various positions of the closure element;
  • figure 7 shows a quarter longitudinal sectional view of a variant of the device from figure 1 ;
  • figure 8 shows an example of an elastic ring for a device from figure 1 .
  • a device 1 for packaging and dispensing contains a product P.
  • the product P contained is preferably a cosmetic product such as a care serum or cream.
  • the device 1 has a container 2 for containing and storing the product before it is sold and then during its useful life with a user, and a closure member 3 for closing off the container 2 in order to preserve the stored product.
  • the closure member 3 has a pipette 6 for withdrawing and dispensing a dose of product P contained in the container 2.
  • the product P is in the form of a fluid having a viscosity suitable for being sucked up into the pipette 6.
  • the container 2 is a hollow body that extends mainly along a longitudinal axis X-X, is closed at one end by an end wall, and is open at the other end.
  • the opening in the container 2 is defined by a neck 21 that extends from a shoulder of the container 2.
  • the axis of the opening corresponds to the longitudinal axis X-X.
  • the neck 21 has a circular cross section, but it could have a different one.
  • the neck 21 may have a narrowing 22 located between the shoulder of the container 2 and the upper rim of the neck 21 .
  • the container 2 is produced for example from glass, or from a thermoplastic material. It may, for example, be obtained by an extrusion blow molding technique. It may also be obtained by joining together a number of components. It has for example a circular or ovoid cross section, but it may also have any other cross-sectional shape.
  • a sealing member 10 is fixed in the opening defined by the neck 21 of the container 2. Besides the function of sealing the container 2 when the closure member 3 is positioned on the container 2, this sealing member 10 also has the function of wiping the pipette 6 in order to scrape off most of the product P deposited on the outer surface of the pipette 6 when the latter is withdrawn from the container 2.
  • the sealing member 10 is for example produced from polyethylene (PE), butadiene-acrylonitrile copolymers (NBR) or any other material suitable for forming impermeability.
  • PE polyethylene
  • NBR butadiene-acrylonitrile copolymers
  • the sealing member 10 is an approximately tubular seal and is engaged at least partly with a tight fit against the inner wall of the neck 21 so as to form cylindrical impermeability between the sealing member 10 and the neck 21 of the container 2.
  • the sealing member 10 may comprise an upper edge 1 1 intended to come into axial contact with the upper peripheral rim of the neck 21 .
  • the sealing member 10 may comprise an external annular boss 12 which is engaged in an internal annular groove 23 in the neck 21 in order to axially retain the sealing member 10 in the neck 21 .
  • the lower end 13 of the sealing member 10 is formed with a frustoconical wall which is flared from bottom to top so as to define a through-orifice toward the inside of the container, said orifice being narrower than the opening in the neck 21 and coming into contact with the external surface of the pipette 6.
  • the container 2 may be topped by a cover band 30 in order to ensure the appearance and overall design of the device 1 .
  • the band 30 has a means 31 for retaining the closure member 3 on the container 2.
  • the means 31 for retaining the closure member 3 on the container 2 has an elastic ring 36 mounted between the band 30 and around the neck 21 of the container 2.
  • the band 30 is fixed to the neck of the container 2, keeping the ring 36 around the neck 21 .
  • the band 30 comprises an upper part 32 and a lower part 33.
  • the upper part 32 is fixed on the neck 21 in a non-removable manner.
  • the inner wall of the upper part 32 of the band 30 is fitted tightly to the outer wall of the neck 21 .
  • the upper part 32 of the band 30 may be fixed to the neck 21 by any appropriate means, for example by adhesive bonding, with a tight fit or by snap- fastening.
  • the end of the upper part 32 of the band may have a projection above the upper peripheral rim of the neck 21 such that the upper edge 1 1 of the sealing member 10 is positioned between the upper peripheral rim of the neck 21 and the projection of the band so as to keep the sealing member 10 axially in the neck 21 .
  • a bottom portion of the upper part 32 of the band 30 comprises a window 34 that opens out next to the top portion of the narrowing 22 of the neck 21 . This bottom portion of the upper part 32 of the neck 30 is thus not in contact with the outer wall of the neck 21 .
  • the section of the upper part 32 of the band 30 is narrower than the upper section of the body of the container 2 at the shoulder between the body of the container 2 and the neck 21 .
  • the cross section of the upper part 32 of the band 30 may be non- circular, and in particular approximately square.
  • other sections of the upper part 32 of the band 30 are conceivable, such as polygonal, ovoid, circular or other cross sections.
  • the section of the upper part 32 of the band 30 does not have to be homothetic with respect to the section of the body of the container 2.
  • the section of the neck 21 may be non-circular.
  • the lower peripheral edge of the lower part 33 of the band 30 is positioned against or substantially against the shoulder between the neck 21 and the body of the container 2.
  • the lower part 33 of the band 30 is connected to the upper part 32 by a shoulder such that the cross section of the lower part 33 is wider than the cross section of the upper part 32.
  • the section of the lower part 33 may be matched to the section of the container 2 in order to continue the surface of the container 2.
  • the inner wall of the lower part 33 of the band 30 is positioned facing the narrowing 22 of the neck 21 so as to form an approximately annular space 39 between the lower part 33 of the band 30 and the neck 21 of the container 2.

  • POM polyoxymethylene
  • ABS acrylonitrile butadiene styrene
  • the elastic ring 36 forms an annulus having an inside diameter greater than the outside diameter of the narrowing 22, and having an outside diameter greater than the diameter of the inner wall of the lower part 33 of the band 30.
  • the elastic ring 36 is mounted prestressed in the band 30. This prestressed position of the ring 36 is called the rest position of said ring 36.
  • the elastic ring 36 comprises an actuating means 37, such as a button, placed in the opening 35 in the band 30. In the rest position of the ring 36, the actuating means 37 may project from the wall of the lower part 33 of the band 30.
  • the elastic ring 36 also comprises a retaining element 38. This retaining element 38 is intended to lock the closure member 3 on the container 2 as will be described hereinbelow.
  • the retaining element 38 forms for example a catch positioned in the window 34 in the bottom portion of the upper part 32 of the band 30. In the rest position of the ring 36, the retaining means 38 projects from the wall of the upper part 32 of the band 30.
  • the retaining element 38 is positioned on the same side of the ring as the actuating means 37.
  • the catch is, for example, positioned at the end of a tab which is connected at its other end to the ring 36 and to the actuating member 37.
  • the ring 36 When the user exerts a pressure on the actuating means 37, the ring 36 is deformed and the actuating means 37 is moved toward the neck 21 along with the retaining element 38, such that the retaining element 38 no longer projects from the window 34.
  • the actuating means 37 is thus able to move radially with respect to the container 2.
  • the actuating means 37 and the retaining element 38 are connected to an elastic ring 36, although it is possible for them not to be connected to the elastic ring.
  • this example describes an elastic ring, but any other elastic return member may be used.

  • the closure member 3 has a cap 4, a push button 7, a pumping mechanism, and the dispensing pipette 6.
  • the cap 4 is formed by a tubular sleeve extending mainly along the longitudinal axis X-X and forming a tubular external envelope serving as an element for gripping the closure member 3 in particular in order to separate it from the container 2.
  • the upper end of the sleeve has an edge extending radially toward the inside of the cap 4 and defining a through-orifice of axis X-X between the inside and the outside of the cap 4.

  • the tubular jacket 51 of the pump body 50 closed by the piston 74 thus forms a chamber with a volume that varies with the sliding of the piston 74.
  • the movement of the push button 7 relative to the pump body 50 allows pumping by sucking up the product P into the pipette 6 when the free end 62 of the pipette 6 is dipped into the product P and when the movement of the piston 74 in the pump body 50 causes an increase in the volume of the chamber.
  • sliding of the piston 74 in the opposite direction causes a decrease in the volume of the chamber and allows the product P located in the pipette 6 to be expelled.

  • the closure member 3 In order to pass from the position shown in figure 5 to the position shown in figure 6, the closure member 3 is separated from the container 2 and the user exerts a pressure on the push button 7 by holding the cap 4.
  • the push button 7 then slides with respect to the cap 4 in the direction of the pump body 50 while compressing the spring member 5.
  • the pump body 50 is kept fixed with respect to the cap 4 since the force exerted by the spring member 5 on the panel 58 of the pump body 50 presses the protuberances 54 against the lower edges of the cavities 44 in the insert 42 fixed in the cap 4.
  • This disposition of the pump body allows the device to function optimally and an identical product dose volume to be obtained upon each use.
  • the push button 7 is in the depressed position corresponding to the position in which the push button 7 is located after a dose of product P has been dispensed.
  • the piston 74 is thus in a bottom position more or less in contact with the bottom of the pump body 50, and the volume of the chamber is thus at a minimum.

  • the upper edge of the cap 4 may have an indentation, the bottom part of which is flush for example with the plate 71 when the push button 7 is in the depressed position.

  • the device of this variant functions in a similar way to the above device except that the action carried out by the user to move the closure member 3 from its locking position into its unlocking position and vice versa is an unscrewing or screwing movement.
