Definitions

  • the present invention relates to the technical field of packaging, and more specifically to that of the packaging and distribution of a liquid or viscous product intended to be stored in a sealed manner and to be distributed in the form of unit doses at using a distributor assembly.
  • the subject of the invention is more particularly a device for packaging and dispensing a fluid product, including a reusable protective assembly for covering an internal unit including a container intended to contain the product.
  • This product packaging and dispensing device typically comprises a dosing assembly suitable for dispensing a dose of the product.
  • the delivered dose must be constant and precise.
  • the metering assembly typically comprises a metering pump without air intake (classically designated by the English expression “airless”).
  • the internal part is a reservoir part which includes the container, the associated piston and a container connection interface to connect the dispensing part of the head to the reservoir of the lower internal part (after filling), which requires making a sealing and maintenance of the assembly by an upper outer peripheral part belonging to the metering assembly.
  • the inlet of the metering pump extends to a tubular end of the reservoir opposite the bottom of the reservoir part.
  • connection interface makes it possible to prevent access to the container-head connection zone, in order to prevent any air ingress.
  • this type of limiting configuration prevents the reuse of certain parts of the device, in particular if it is desired to be able to change the reservoir part (for which the contents have typically been exhausted) and replace it with a new internal unit, filled with a new one. content that can be dispensed in dose form.
  • necked containers proves to be ill-suited to mass production, in particular when the liquid product is viscous (the product can for example correspond to a wide range going from 1000 centipoises (cps) to 40000 cps ). Indeed, it has been observed that the narrowness of the opening due to the presence of a neck has the effect of slowing down the rate of filling. In addition, it is necessary, with a container with a neck, to provide a format of the covering body which closely depends on the container used, except to lose a lot of internal space without any use whatsoever.
  • the object of the invention is to remedy one or more of the drawbacks of state-of-the-art devices and to propose a packaging and dispensing device which is very suitable for the various requirements of practice (in particular the requirement of sealing) and compatible with very different packaging options while allowing a dismantling that does not affect the integrity of the distribution circuit.
  • This type of device advantageously makes it possible to have a high-performance internal unit, which can be changed, by reusing several protective parts consisting of the external body and the upper connector, as well as a cap, if necessary, which is mounted on the connector. upper, for example above the outer side wall.
  • a cap for example above the outer side wall.
  • the operations are easy, requiring no tools and no disassembly action concerning/affecting the sealing parts of the internal unit. This ensures that the distribution circuit is perfectly intact from one use to another, even in the event of replacement. Indeed, the retaining ring prevents access to the receptacle-head connection zone, to prevent any air ingress.
  • the body protects the container and the upper connector protects the sealing ring.
  • a functional part of the device which is entirely internal (internal unit), formed by the head of which the metering assembly and the reservoir part form part.
  • This functional part which satisfies the high sealing requirements, in particular in the cosmetics or pharmaceutical field before and even after the first use, can be designed separately.
  • the functional part can thus be produced in a very large number of copies (of the order of several million for example), while being integrated into a personalized device (in its format and in the choice of body material) thanks to adaptation of the upper connector and the body, and possibly by sizing/adapting the retaining ring.
  • the movable wall of the container is thus very well protected. It makes it possible to ensure a sealed separation and to maintain an identical pressure between the fluid product contained in the reservoir and the air in the peripheral volume between the container and the body.
  • the internal unit can be perfectly immobilized in an internal housing delimited by the body and the upper connector, in particular by not being able to move axially.
  • the sliding of the reservoir part can be blocked in the usual way by a retainer (contact of the reservoir part against the bottom of the body or axial contact of the ring of the internal unit against the top of the container).
  • a sandwiching effect for example between the wall/radial part of the connector and the upper body may be preferred.
  • the removal of the internal unit can also involve a rotation, for example when it suffices to unscrew to extract the internal unit from the body.
  • the internal unit is axially movable and is easily removed from the hollow body, without tools or delicate unlatching operation. However, it takes longer to disengage the internal unit, so free insertion of the reservoir portion into the body is preferred.
  • the retaining ring may extend radially at a distance from the outer side wall and/or is capable of sliding along this outer side wall, having an outer side face devoid of any projecting relief for contact against the outer side wall.
  • the ring is free to rotate around the longitudinal axis of the container, so that during insertion of the reservoir part into the body and in a fully inserted state of the reservoir part (for which the ring bears axially against an abutment surface of the body perpendicular to the longitudinal axis), the internal unit is free to rotate.
  • This type of arrangement allows easy assembly, without the need to check any accuracy in the angular positioning of the internal unit.
  • the ring has a means of indexing in rotation relative to the body, so that the internal unit is locked in rotation in a completely inserted state of the part with the reservoir (state for which the ring is resting axial against an abutment surface of the body which is perpendicular to the longitudinal axis).
  • the ring can preferably be freely sliding, in the fully inserted state of the internal unit.
  • the rotational indexing means can cooperate with a guide relief provided on the body, so as to form an error-proofing means (possibly with a marking visible at the time of assembly between the internal unit and the bottle forming the body). This can avoid losing the correlation between the external body and/or the connector, and the content or type of internal unit to be used. This can also facilitate the detection, if any, of a counterfeit.
  • the container is preferably not narrowed at its upper end and the opening can typically define a diameter of at least 15 or 16 mm, preferably greater than 20 mm.
  • a diameter of the filling opening may correspond to at least 75 or 80% of a container diameter defined around a piston at the lower end of the container.
  • the dimension of the diameter of the opening can be greater, within the limit of the diameter of the container (therefore corresponding, if necessary, to 100% of the section of the container).
  • the first fastening means and the second fastening means form a bayonet-type connection system. This arrangement makes the attachment both robust and easy to unlock.
  • the second fixing means are formed on an internal face of the upper connector, preferably on the internal face of the tubular external part, in an annular zone which is located lower than (entirely below) the retaining ring in the configuration locked from the connector.
  • the upper connector has at least two internal lugs, intervening to make the bayonet-type connection.
  • the upper connector may also have axial slots, in the same outer skirt of generally tubular shape, belonging to said upper connector.
  • the axial slots make it possible to obtain axial movement in the skirt, which facilitates assembly and disassembly operations.
  • Such slots can advantageously be hidden by an annular piece, for example a piece forming a hoop, which surrounds the outer skirt.
  • the connector may have a main part forming the outer skirt and the radial support/holding portion from above against the internal unit, and an auxiliary part without contact with the internal unit and constituting the upper part of the outer side wall of the device.
  • the hoop-forming part typically constitutes such an auxiliary part of the upper connector.
  • each of the slots is preferably designed to separate a flexible portion of the skirt from an adjacent portion of the skirt which is stiffer than said flexible portion.
  • the part forming a hoop is part of the connector and can, in a state at rest of the flexible portions, extend radially at a distance towards the outside with respect to each of the flexible portions, the part forming a hoop having an internal collar or similar section reducing the upper opening of the part, adapted to come into engagement with at least one relief included in the main part of the upper connector by forming a means of blocking a relative rotation between the main part and the auxiliary part of the connector.
  • the latter laterally envelops the outer skirt of the upper connector, forming a continuous periphery constituting a portion of the side wall of the device.
  • the hoop-forming part can be metallic, provided with a metallic external coating or made of glass.
  • At least one anti-rotation relief is provided externally on the upper connector, preferably on the radial part thereof, in order to prevent relative rotation around the longitudinal axis between the part forming the hoop and the upper connector.
  • the upper connector includes a hoop-forming part which may have a circular opening with a diameter equal to the outer diameter of an upper sleeve or intermediate between the outer diameter of an upper sleeve of the upper connector and the diameter of the outer part tubular.
  • the hoop-forming part covers at least 90% of the radial portion (this percentage corresponding to a surface ratio between the upper surface of the radial portion and the upper surface of the hoop-forming part.
  • the upper connector has an outer skirt comprising at least one portion with radial outward movement, which is preferably thinner than the rest of the upper connector, all or part of the first fixing means being located in the at least one portion with radial outward movement.
  • the upper opening of the body has a diameter which is substantially equal to an external diameter of the container.
  • the volume/capacity of the device is optimized, by minimizing the dead volumes, the peripheral volume being able to be reduced to a minimum.
  • the difference between the maximum internal diameter of the hollow body and the (substantially constant) external diameter of the container may be less than 20 mm, preferably less than or equal to 15 mm, for a container having an internal diameter typically greater than or equal to 25 mm. More generally, the ratio of internal diameters can easily exceed 0.6:1, between the internal diameter of the container and the internal diameter of the hollow body.
  • the retaining ring has a cylindrical outer face, the outer surface of which is preferably smooth.
  • the grip edges/edges distributed on the outer face of the container and on the head come to engage in a housing of the retaining ring, formed by an internal hollowing or between two reliefs spaced axially from each other of the retaining ring , the housing being located in an intermediate axial position, and at a distance, respectively between a lower edge of the cylindrical outer face and at least one upper edge of the cylindrical outer face.
  • the upper connector has internal lugs which are each elongated in a circumferential direction between a front end, preferably tapered, and a rear end, and each have an intermediate hollow, between the front end and the rear end, in order to receive in the locked configuration a projection formed integrally with the bottle, which is located in the side cavity and which makes it possible to constitute the abutment surface.
  • the side wall has a cross section whose profile is substantially constant from the lower end to the annular upper edge.
  • the side wall has a cross section whose profile evolves in the direction of a progressive enlargement of the cross section while moving away downwards from the tubular outer part.
  • the container In the case of a covering in at least two superimposed parts, the container is typically introduced into the body from above, through the opening of the ring, which can make it possible to avoid an additional operation of closing the bottom. by a lid after the container has been put in place.
  • the upper part of the container forms a seat for the closure element (in particular an insertion portion of this element), while the ring rests on the top of the body to delimit a snap-in zone, screw -à-vis the outer periphery of the upper part of the container.
  • a peripheral part of the head can then fit into this snap-fastening zone, so that by fixing the head on the lower reservoir part, both the seal against the container and the maintenance between them of the component parts of the internal unit are achieved.
  • the packaging and dispensing device 1 comprises a body 2, typically a bottle body, with a bottom 2a which defines a support base B, a container 4 which extends (entirely, essentially or in part) to inside the body 2 and makes it possible to store the liquid or viscous product 5 to be dispensed, a stopper element S, preferably made of thermoplastic material, assembled to the container 4 in a sealed manner and which forms part of a head 6 for dispensing or tip.

  • a user can obtain the device 1 including its internal unit 25 and, at the same time, internal units 25' forming compatible cartridges or refills to be inserted internally between the body 2 and the upper connector 17 , 117.
  • the tightness of all the internal units is obtained in the same way, so that the internal units 25, 25' can be stored for a long time without altering the product 5 (fluid or viscous content).
  • the upper connector 117 also has a sleeve upper 118 similar to the sleeve 18 of the connector 17 of the embodiments shown in particular on the Figures 8A-8B .
  • Such an upper connector 117 has many similarities with the upper connector 17 provided in the embodiment of the preceding figures and differs essentially in that the upper section 116 extends the outer face upwards to one end forming the edge 117b which surrounds the actuating portion 10, so that a cap 16 is not necessary.
  • the actuating portion 10 also withdraws.
  • the actuating portion 10 can be retained from above by one or more protruding interior portions or flange provided on the side of the upper edge 117b and mounted on the movable part of the pump 7 without retaining relief, this which makes it possible to separate the internal unit 25 from the connector 117 - actuation portion 10 assembly. Indeed, by raising the connector 117 while firmly holding the reservoir part R of the unit 25, the portion of actuation 10 of the rod 11a, without significant effort.
  • the internal unit 25 after extraction from the body 2, in order to separate the pusher member 111 from the rest of the head 6 of distribution which belongs to the internal unit 25.
  • the ring 24 provided in the device with the upper connector 117 of the figures 13 and 14 may be identical or very similar to that of the preceding figures. It is understood that the head 6 here has a push member 111 which can be mounted internally in an upper compartment defined by the upper tubular section 116. The transverse wall forming the radial portion 117a separates this compartment upper and a lower compartment in which the top of the reservoir part R is housed. relative to end 117b, in the non-actuated position. The actuation of the push member 111 can be facilitated thanks to a notch 117c formed at the upper end 117b of the upper connector 117 ( figure 14 ). This is ergonomic, by making it possible to increase the area of contact between a finger of the user and the push member 111.
  • a slot 130 here opposite the notch 117c, can allow the outlet of the diffuser member 14 to project radially outwards beyond the outer face defined by the upper section 116, or to be flush relative to this face.
  • the figure 14 shows a slot 130 which opens out at its upper end, such a slot 130 can also be placed differently, without opening out.
  • the slot 130 is here vertical and makes it possible to guide the sliding without the possibility of significant rotation of the pusher member 111.
  • the body 2, the upper connector 117 and optionally the push member 111 can be reused with a new internal unit, after disassembly/assembly operations (the principle illustrated in the diagram of the Figures 11A-11B remaining applicable).
  • the filling opening O has a diameter D2 which may be substantially identical to the internal diameter D1 of the container 4 on the side of its lower end 4c, possibly less than D1, and preferably at least equal to 90%, or even 98% or 100% of D1.
  • the use of a container 4 without a neck makes it possible not to slow down the filling operation.
  • the diameter of the filling opening O is typically greater than 15 mm and generally exceeds half the diameter D or representative characteristic of the outer periphery of the body 2 at least close to the shoulder E2. More generally, the filling opening O may have a diameter at least equal to 75% of the diameter of the opening 300 of the ring 24.
  • the body 2 is made in one piece.
  • the side wall 2b of the body 2, tubular, can have a constant cross section as in the case of the figure 12 or include at least one bulge 60 in an intermediate part as in the case of the figure 10 .
  • the shape of the section can also vary (for example with an oval section only at the level of a bulge).
  • the body 2 can have any type of geometry with a circumference suitable for gripping and which exceeds the maximum circumference of the container 4, so as to avoid any contact radial between the container 4 and the side wall 2b, except for the area located above the shoulder E2 of the body 2. It is also understood that the ring 24 is located above the upper opening 13 of the body 2 without interfering with filling opening O.
  • the device 1 can be compact and is well suited for dispensing the same precise doses of liquid or viscous product.
  • the device 1 is typically in the form of a vial with a dosing head/dosing tip and designed particularly for cosmetic applications and other applications requiring a high degree of customization of the outer side wall SW.
  • the device 1 is particularly well suited to an “airless” type metering pump 7 which reduces the risk of contamination while allowing almost total evacuation of the product 5. Between the distribution channel 8 of the pump 7 and the interior of the container 4, there is no venting possible, the ring 24 guaranteeing in this respect the maintenance of a seal. It is also understood that the device 1 has a very limited number of moving or flexible parts, so that it is particularly robust and remains effective after a large number of uses. The integrity around the container 4 and the pump 7 is maintained despite any shocks, which makes it possible to guarantee sealing.
  • the container 4 and the dispensing head 6 can form an integrated sub-assembly, in the form of a pre-assembled unit, which can be installed (in one piece) between a body 2 with protection and covering function and an upper connector, typically a rigid body 2 and connector provided with one or more flexible parts incorporating reliefs or lugs for coupling in rotation on the upper fixing zone of the body.
  • the user can therefore easily remove the internal unit, as shown in the figure 11A of the sub-assembly forming the external side wall SW, in order to reload the device 1 (replace the empty cartridge formed by the internal unit 25 with a full cartridge).
  • This makes it possible to reuse the upper connector 17, 117 and the body 2 several times, these reusable parts possibly being finely elaborated and relatively expensive, and thus extending their useful life beyond the useful life of the product 5 contained in the container 4 of the internal unit 25.
  • the figures show a container 4 made in two parts to facilitate the insertion of a piston 29, it is also possible to insert into the body 2 a container with a movable bottom.
  • the holding part 26 can be replaced by an equivalent assembly of at least two parts having both an axial thrust effect on the plugging element S and holding the metering pump 7.
  • the the internal unit 25 can have another type of dosing assembly 15, possibly with air inlet, for example in options with filtration of the incoming air which can circulate (in the form of filtered air if necessary) to the inside of the tank.
  • the internal unit 25 may optionally have a linear guide relief along the body, for example on the ring 24, and/or any means of indexing in rotation, for example a peg or orifice for a peg, may be provided in a part of the body 2 in contact with the container 4 or the ring 24.
