Definitions

  • the present invention relates to devices for packaging and dispensing a liquid or pasty product.
  • Devices comprising a container having a cylindrical body in which a piston can slide.
  • the latter delimits inside the container a space of variable volume containing the product.
  • the container is provided with a pump for withdrawing product from said space.
  • the piston moves in the container in response to a product leaving when the pump is actuated, to keep the stored product away from the air in the container.
  • An advantage of this type of device is that it can be used both upside down and upside down.
  • the use of a movable piston poses problems of product leakage when the latter is a liquid, so that the use of these known devices has remained limited to the packaging and distribution of viscous products such as a toothpaste paste.
  • the German utility model G 90 13 168.1 discloses a device for packaging and dispensing a liquid or pasty product, comprising a container capable of containing said product, this container having a product outlet orifice, equipped with a pump comprising a valve able to allow the product to leave without entering the air, the container further comprising a bottom wall constituted by a pocket delimiting inside the container a space containing said product, said pocket being capable of move in the container in response to a product departure to reduce the volume of said space and keep the product away from the air in the container.
  • the pocket is fixed at one end at its periphery to the container and it is capable of deforming to reduce the volume of said space until it substantially matches the shape of the interior of the container.
  • the pocket is folded on itself when the container is full of product and it unfolds gradually as the product leaves.
  • the bag is trapped inside the container by a rigid wall pierced with an orifice allowing air to enter the container, on the side of the face of the bag which is opposite to the product.
  • the device described in this German utility model is used with the pump at the bottom and is not suitable for use with the pump at the top because there is a risk in this case that the product is retained in a cavity formed by the folds of the bag and does not can be dispensed by the pump.
  • the pocket could cover the air intake opening in the container and hinder the correct functioning of the device.
  • German patent application DE 1,586,797 discloses a device for packaging and dispensing a liquid or pasty product comprising a container with a deformable wall capable of containing said product, this container having an outlet orifice equipped with a valve able to allow the product to leave without entering the air, the container further comprising a pocket delimiting inside the container a space containing said product, said pocket being able to move in the container in response to a product leaving to reduce the volume of said space and keep the stored product away from air in the container, this pocket being fixed at one end at its periphery to the container and being able to expand to reduce the volume of said space.
  • the pocket fills with air through an opening in the container, fitted with a valve intended to prevent the air from escaping from the pocket when pressed on the walls of the container to cause the expulsion of the product.
  • the pocket being elastically deformable, it contains air which is in the compressed state.
  • the object of the present invention is to propose a new device for packaging and dispensing a liquid or pasty product, of the type comprising a container capable of containing said product, this container having a product outlet orifice equipped with a pump comprising a valve capable of allowing the product to leave without air entering, the container further comprising a bottom wall constituted by a pocket delimiting inside the container a space containing said product, said bag being able to move in the container in response to a product departure to reduce the volume of said space and keep the product stored away from air in the container, said bag being fixed at one end at its periphery to the container and being able to deform to reduce the volume of said space until it conforms substantially to the shape of the interior of the container, which can be used with the pump at the top or the pump at the bottom and which allows to distribute almost all of the product contained inside the container.
  • the pocket is made of an elastically deformable material.
  • the depression created in said space by the departure of the product causes the deformation of the pocket in the direction tending to decrease the volume of said space, until the cancellation of said depression.
  • the pocket advantageously occupies, thanks to its elasticity, in its state of maximum expansion almost all of the volume initially occupied by the product, regardless of the shape of the container.
  • the invention thus allows a wide variety of shapes for the container, while the devices of the prior art with movable piston necessarily had to have a cylindrical body.
  • the pump is located in the upper part of the container during use.
  • the pocket is capable of deploying at first without its wall tensing and then, at a second stage, of expanding elastically.
  • said pocket can be deployed initially without its wall stretching to occupy more than half of the space initially occupied by the product, then in a second step, the pocket can expand elastically to occupy the remaining space freed up by the product.
  • the pocket is capable of expanding elastically from a certain degree of emptying of the container, it has fewer folds when the container is full than the pockets of known devices which are not made of an elastic material; so the risks associated with blocking the air intake opening are reduced.
  • the pocket is internally provided with a lining made of a material which is not elastically deformable but very impermeable to gases, said lining being able to deploy to accompany the deformation of the pocket until the wall of the latter is stretched.
  • the pocket is substantially stretched when the container is full.
  • the pocket can be in the form of a substantially planar elastic membrane when the container is full.
  • the latter can be substantially flat and shaped so that when empty, the bag has moved over a relatively small height, for example between 15 and 20 mm.
  • the device comprises sealing means capable of isolating the interior of the pocket from the ambient air, at least before the first use of the device.
  • These sealing means constitute with the pocket a double sealing barrier favorable to a long-term conservation of the product contained in the container.
  • these sealing means when in place on the container, prevent the bag from inflating by air intake and hinder the operation of the pump used to withdraw the product.
  • the closure means can thus advantageously serve as a tamper-evident witness, insofar as their presence, intact, on the device indicates to the user that it has not been possible to use it previously in a normal manner.
  • FIGS. 1 and 2 show a device 1 for packaging and dispensing a liquid or pasty cosmetic product P, in accordance with the invention.
  • a device 1 for packaging and dispensing a liquid or pasty cosmetic product P in accordance with the invention.
  • This device 1 comprises a container 2 with a rigid wall, generally symmetrical in revolution in the example described, formed by the snap-fit assembly of a body 3 on a base 4.
  • the latter comprises an upper tubular skirt 5 provided at its end free of a rim 6 radially projecting inwards.
  • the body 3 is provided with a lower tubular wall 7, of outside diameter adapted to engage in the tubular wall 5.
  • the tubular wall 7 is connected to the rest of the body 3 by a narrowing of section 8 defining an external annular groove in which the rim 6 engages at the end of the snap fastening of the body 3 on the base 4.
  • the latter comprises a lower tubular skirt 9, externally threaded, for its screwing on a base known in itself and not shown .
  • the body 3 is closed at its upper part by a wall 15 having a neck 16 extending upwards, provided at its upper end with an annular flange 17 radially projecting outwards.
  • a pump 18 known in itself and not described is fixed to the neck 16.
  • This pump 18 comprises a pusher 19 for dispensing product, and it is provided below with a cap 20 shaped to snap onto the annular rim 17 of the neck 16.
  • the pump 18 comprises a tube 21 for taking the product P from the container 2.
  • This tube 21 is engaged in the opening of the neck 16 and extends by its lower end under the wall 15 in an interior space 23 of the container 2 containing the product P.
  • Lateral openings 24, the role of which will be explained below, are arranged at the lower end 22 of the tube 21.
  • a cover 25 covers the neck 16 of the body 3. This cover 25 fits onto the body 3 as shown in FIGS. 1 and 2 until it abuts by its lower edge against a shoulder 26 formed on the external surface of the body 3, and it is provided above in its center with a passage for the pusher 19.
  • the device 1 comprises a pocket 28, having a certain elasticity and appearing in the example described in the form of a bellows in the folded state delimiting inside the container 2 two spaces, one of which is constituted by the interior space 23 above, contains the product P, and the other, inside the bellows, bears the reference 29.
  • the pocket 28 constitutes a deformable waterproof barrier separating the spaces 23 and 29.
  • the interior space 29 communicates through the openings 11 with the outside when the shutter means 14 are removed, as shown in FIG. 2.
  • the pocket 28 is fixed at its lower end at its periphery to the container 2, so that the interior of the bellows communicates via the openings 11 with the ambient air. More specifically, the wall 28 is pinched at its lower end at its periphery between the tubular skirts 5 of the base 4 and 7 of the body 3.
  • the base 4 has an annular lip 30 coaxial with the skirt tubular 5 and defining with the latter an annular groove 31 in which engages the lower end of the tubular skirt 7 of the body 3.
  • the annular lip 30 improves the strength and tightness of the fixing of the pocket 28 on the container 3 by pinching the latter against the radially internal surface of the tubular skirt 7.
  • the wall of the pocket 28 pinched between the body 3 and the base 4 constitutes a seal ensuring a hermetic mounting of the body 3 on the 'base 4.
  • closure means 14 appear in the example described in the form of a cap or suction cup comprising a central housing retained by friction on the fixing foot 12.
  • the wall delimiting this housing radially is extended upwards by a sealing lip 32 extending obliquely radially outward and coming to be applied by its free end to the wall 10 around the openings 11 when the cap 14 is in place.
  • the latter is advantageously provided at its lower end, as shown, with a tongue 33 facilitating its removal.
  • a vacuum is created in the interior space 29 before the cap 14 is put in place by sucking the air through the openings 11 with the aid of an appropriate device, to cause the pocket 28, as shown in FIG. 1.
  • the pocket 28 then occupies a reduced volume in the container 2.
  • the pocket 28 is folded back on itself by suction through the openings 11 while the pump 18 and the cover 25 are not yet in place on the container 2.
  • the container 2 is filled with product under vacuum through the neck 16 then the pump 18 is slammed on the latter and the cover 25 is attached.
  • the pocket 28 is secured to the base 4 alone.
  • the container 2 is filled before the base 4 is attached to the latter with the pocket 28 in the folded state.
  • the filling is then carried out from the bottom, with the pump 18 already in place on the body 3.
  • the base 4 provided with the pocket 28 kept in the folded state by the cap 14 is slammed on the body 3 .
  • the pump 18 includes a valve arranged in a manner known per se to allow the product P to be withdrawn without re-entry of air by the tube 21 into the container. If the user attempts to collect product P by pressing the pusher 19 while the cap 14 is still in place, the pump cannot function correctly to dispense product. By cons, when the cap 14 is removed, the pocket 28 can inflate in the container 2 to reduce the volume of the interior space 23, so that there can not appear in the latter a depression opposing a departure of product. During use, the bag 28 deploys upwards along the axis of symmetry of the container 2 as shown in FIG. 2. The bag 28 can inflate thanks to the air inlet inside this through the openings 11 to occupy all the volume in the container 2 which is released by the product P.
  • the pocket 28 is made of an elastically deformable material such as rubber or a thermoplastic elastomer.
  • One can use a blow molding technique, injection molding or dip molding in particular.
  • the pocket 28 can also be constituted by an assembly of at least two layers of different plastic materials.
  • the pocket 28 may also have a variable thickness making it possible to promote the expansion of selected areas of the pocket.
  • the pocket 28 can be deployed to occupy up to approximately 80% of the volume initially occupied by the product P before its wall is stretched. It is then thanks to its elasticity that the wall of the pocket can be more tight to match the shape of the interior of the container and occupy the 20% of the initial volume remaining.
  • the pocket 28 Given its attachment to the container at its periphery at its lower end, the pocket 28, when it elastically deforms, is first pressed against the wall of the container 2 adjacent to the base 4. The pocket 28 then ensures by progressively pressing against the wall of the container from the bottom upwards the rise of all of the product P in the direction of the sampling tube 21.
  • the pocket 28 is provided internally with a lining made of a material which is not elastically deformable but very impermeable to gases such as polyethylene.
  • the interior of the lining communicates with the ambient air through the openings 11 and the lining can inflate to occupy a maximum of approximately 80% of the volume initially occupied by the product.
  • the pocket deforms thanks to its own elasticity to occupy the 20% of the initial volume remaining, with the appearance of a depression in the interval between the pocket and its lining.
  • FIG. 3 There is shown in Figures 3 and 4 a device 40 according to a second embodiment of the invention.
  • the device 40 differs from the previous one mainly in that a valve 41 is arranged in the air passage making the interior space 29 communicate with the exterior.
  • This valve 41 is shaped to allow an entry of air into the interior space 29 and prevent an exit of air to the outside.
  • the valve 41 only opens when the air enters the pocket 28 when the latter expands and constitutes with the latter when it is at rest in the closed state a double sealing barrier, favorable to long-term storage of the product contained in the container.
  • the pocket 28 can, as in the previous embodiment, inflate until its wall tightens then deform elastically to occupy, as shown in FIG. 4, almost the entire volume initially occupied by the product P to be dispensed.
  • the valve 41 comprises a membrane 42 applied at its periphery to the base 4 and able to deform elastically to release an orifice 43 for the passage of air towards the interior space 29.
  • the membrane 42 is applied to the base 4 at by means of a retaining part 44 forming a tap, slammed on the base 4 with a possibility of rotation around the axis of symmetry of the container 2.
  • the membrane 42 has at its periphery an annular rim 45 engaged in an annular groove 46 of the retaining piece 44.
  • the base 4 is provided on its underside with an annular boss 47 pinching the membrane 42 at the base of the rim 45 to ensure a tight hold of the membrane 42 at its periphery.
  • the membrane 42 has a part 47 of hemispherical shape, the concavity of which faces upwards, extended below by a closing finger 48 capable of being applied to the edges of the aforementioned orifice 43, formed on the retaining piece 44
  • the membrane 42 is shaped so that the hemispherical part 47 is slightly pre-stressed at rest and elastically presses the shutter finger 48 against the edges of the orifice 43 to close it.
  • the valve is thus, in the absence of use of the device 40, in a position for closing the passage making the interior space 29 communicate with the exterior.
  • the base 4 and the retaining piece 44 constitute a valve closing, in a determined angular position of the retaining piece 44, the passage communicating the orifice 43 and the interior space 29.
  • the retaining piece 44 comprises a part forming a plug 49a engaged in a lower tubular extension 49b of the base 4.
  • the retaining piece 44 For storage, the retaining piece 44 is turned so as to close the air passage between the plug 49a and the tubular part 49b. The interior 29 of the pocket 28 is thus isolated from the exterior for good preservation of the product.
  • a tearable film can be fixed externally on two adjacent surfaces of the base 4 and the retaining piece 44 to serve as a tamper-evident indicator. When said film is intact, the user knows that the inside of the pocket 28 has remained isolated from the outside and that the normal operation of the pump 18 has not been possible.
  • FIG. 5 shows a device 50 according to a third embodiment of the invention.
  • This device comprises a tap 51 which can take two angular positions. In a first angular position, the valve 51 can allow air to pass between the interior space 29 and the exterior and, in a second angular position, the valve isolates the interior space 29 from the exterior.
  • the base 4 has at its lower part a tubular wall 52 closed at its lower end 53 and traversed radially by a bore 54.
  • the tap 51 is retained by snapping at 55 on the body 3 of the container 2 with a possibility of rotation around the axis of symmetry of the latter. It has a housing 56 which engages closely on the tubular wall 52 of the base 4.
  • a through bore 57 opens at its radially innermost end into the housing 56 and can come into said second angular position of the valve 51, opposite the bore 54 to establish an air passage with the latter and with the interior space 29.
  • the valve 51 is provided, as shown in FIG. 5, with a membrane 58 capable of closing drilling 57 before the first use of the device.
  • This membrane 58 is removably attached to the tap 51 and has a gripping portion 59 allowing the user to remove it when the device is first used.
  • the pocket 28 is folded back on itself by creating a vacuum in the interior space 29.
  • the membrane 58 advantageously plays the role of a valve when it is on the tap 51 by deforming to allow the passage of air towards the outside during the evacuation of the interior space 29 and by preventing the re-entry of air.
  • the operation of the device 50 is as follows.
  • the user positions the bore 57 of the tap 51 opposite the bore 54 of the base 4 and tears off the membrane 58.
