Description

Title of the invention: Packaging device Technical field

[0001] The present invention relates to a packaging device, comprising a base, a cup fixed to the base and a closing cap. Prior art

[0002] The packaging of certain cosmetic products such as care creams is traditionally carried out in jars, in particular with a glass body.

[0003] Furthermore, numerous packaging devices have been proposed which provide for the replacement of only part of the device after its contents have been exhausted.

[0004] The design of these devices requires that this replacement can be done easily by the user, and that the rechargeable nature of the device does not hinder its ease of use or the quality of the packaging, particularly when a watertight closure is required.

[0005] In addition, certain packaging devices use materials of qualitative appearance such as glass or metal, which it is advantageous to be able to integrate into the rechargeable device if this is desired.

[0006] Application FR3067327 describes a packaging device comprising a primary container in which a secondary container consisting of a refill is received, a closing cap being provided to be screwed onto the secondary container, above the primary container.

[0007] Application WO2019058087Al describes a packaging device comprising a refill received in a base, the device being closed by means of a cover provided with an internal thread, screwing onto an external thread of the base.

[0008] Application DE 10 2008037371Al discloses a packaging device comprising a base onto which a cup comprising an externally threaded neck and an external covering skirt is snap-fastened. A closing cap is screwed onto the neck.

[0009] Application JP 2021-172426 describes a packaging device comprising a base having a housing for receiving a cup. The base has a solid part having a side wall provided with hooking reliefs on its inner face. An intermediate part for holding the cup on this solid part is fixed thereon by snap-fastening, the mounting of this part on the solid part being carried out with the closing cap itself fixed on the holding part. Once the holding part is in place, the cap can be detached from it by the user of the retaining piece for accessing the product. The retaining piece is therefore not part of the closing hood, but of the base, remaining attached to the solid part when the hood is removed. Statement of the invention

[0010] The proposal of eco-responsible, environmentally friendly solutions whose design and development take into account environmental issues is becoming a major concern to help meet global challenges.

[0011] In this context, it is important to develop packaging that generates less waste, in particular optimized for the quantity of products transported, in particular by redesigning and / or resizing them in order to reduce the volume and weight of the quantity of packaging.

[0012] It is therefore essential to design more sustainable products, thus making it possible to reduce the quantity of materials used and / or to replace them with more environmentally friendly materials and / or to use recyclable materials in order to reduce the carbon footprint of the product.

[0013] There is a need to further improve packaging devices comprising a base, a cup fixed to the base and a closing cap, in order to have a packaging device which is easy to use and offers new design possibilities, while meeting the conditions required for the preservation of the product and the refilling of the product by replacing the cup when this is desired.

[0014] There is also an interest in reducing the amount of glass in conventional jars used to contain cosmetic products. Summary of the invention

[0015] The invention aims to meet all or part of these needs, and in particular when this is sought to offer reusable eco-responsible containers, in particular refillable at home or in stores in order to reduce the carbon footprint of packaging.

[0016] It achieves this, according to a first of its aspects, thanks to a device for packaging a product, comprising: - A base, presenting a side wall at its periphery, - a cup fixed on the base, intended to contain the product, - a cover configured to removably attach to the base in order to provide access to the product contained in the cup when separated from the base by the user, this cover having a mounting skirt engaging inside the side wall.

[0017] Such a structure has many advantages.

[0018] First of all, it makes it easier to grip the hood and the cup, because they can offer a relatively large gripping surface. This makes the device easier to use, and when the cup is removably mounted on the base, makes it easier to handle for replacement. The use of the device is thus made easier for people who have difficulty handling objects.

[0019] The cup can participate in the centering of the cover when it is placed on the base in order to close the device.

[0020] In addition, the cup can be made if desired with a flared shape, providing a large opening facilitating access to the product contained inside, particularly at the bottom of the cup when there is little product left. This also allows the user to more easily assess the quantity of product remaining.

[0021] The invention also makes it possible, when it is sought to use a qualitative material such as glass for the base, to reduce the quantity of glass used, since the base can be of reduced height relative to the cover. The base can thus be produced with a low glass base, for example of a height less than 20% of the total height of the device in the closed state.

[0022] The hood mounting skirt preferably has a radially external thread. Thus, the hood can be fixed to the base by screwing the hood into the latter.

[0023] The free end of the hood mounting skirt may be located below the lowest level of the product contained in the cup when the hood is fixed to the base. This reflects the fact that the hood may have a relatively large height, compared to that of the base.

[0024] The cover may house a seal that presses against an upper edge of the cup when the cover is in place on the base. This seal is, for example, fixed by snap-fastening into the cover.

[0025] Preferably, the cup is removably attached to the base. This allows the device to be refilled by replacing an empty cup with a full one.

[0026] The cup may comprise a cup-shaped part, extended downwards by a foot fixed to the base.

[0027] The foot of the cup may comprise an outer skirt surrounding first means for fixing the cup arranged to cooperate with second means for fixing the base to ensure the retention of the cup on the base.

[0028] The first and second fixing means are for example chosen from a snap-on fixing, a screw fixing, a bayonet-type fixing, or a clamping fixing.

[0029] Preferably, the first and second fixing means cooperate by snap-fastening, which can allow rotation of the cup in the base, and reduce wear of the seal, as explained later.

[0030] Preferably, the outer skirt of the foot of the cup is of a length at least equal to that of the first fixing means, so as to allow the cup to rest vertically when placed by its foot on a horizontal flat surface.

[0031] The base may include a housing for receiving the foot of the cup. The depth of this housing may be greater than more than half the height of the outer skirt, better still than the entire height of the outer skirt.

[0032] The cup-shaped portion of the cup may have an outside diameter at least 50% larger than that of the foot. This provides a relatively large opening at the upper end of the cup for accessing the product. The largest diameter of the cup may be located at its upper end, and this largest diameter corresponds, for example, to at least 70% of the largest outside diameter of the

[0033] device, better at least 80%, or even 90%. The foot may have a larger outer diameter at least twice smaller than a larger outer diameter of the device.

[0034] Preferably, the cup is mounted on the base with the possibility of rotation about an axis of rotation without axial displacement. This has the advantage, when using a cover comprising a seal applied to the upper edge of the cup in the closed position, of allowing the cup to rotate relative to the base at the start of the unscrewing movement of the cover, to accompany the latter in its movement, and thus to reduce the shearing of the seal on opening and its wear.

[0035] The base advantageously comprises a glass base. This base can be topped with a plastic part produced by injection molding, which defines the side wall of the base and the housing for receiving the cup.

[0036] The apparent height of the cover may represent more than half of the total height of the device in the closed state, better still more than 2 / 3, even better still more than 3 / 4. In particular, the lower edge of the cover may be positioned below the lowest level of the product in the cup, in the closed position.

[0037] The cover may comprise an outer covering piece and an insert fixed therein. The thread of the cover may be made on the insert. The outer covering piece may be made of metal, in particular aluminum. The insert may be made of thermoplastic material.

[0038] A ballast, in particular of annular shape, can be inserted between the insert and the external cladding part.

[0039] Preferably, the cup is completely hidden by the cover in the closed state of the device.

[0040] The exposed portion of the base may represent less than 30% of the total height of the device in the closed state. The height of the base may represent less than 20%. This makes it possible to minimize the quantity of glass used.

[0041] The invention also relates, according to another of its aspects, independently or in combination with the above, to a device for packaging a product, comprising: - A base, presenting a side wall at its periphery, - a cup fixed on the base, intended to contain the product, - a cover comprising a seal applied to the upper edge of the cup in the closed position, configured to be removably fixed

[0042] to the base in order to free access to the product contained in the cup when separated from the base by the user,

[0043] the cup being mounted on the base with the possibility of rotation around an axis of rotation without axial displacement, so as to allow the cup to rotate at the start of the movement of unscrewing the cover relative to the base to accompany the latter in its movement.

[0044] In particular, the cup can be snap-fastened onto the base in a manner that allows for this rotation.

[0045] The invention, according to this second aspect, makes it possible to reduce the shearing of the seal at the end of screwing or at the start of the opening movement.

[0046] The invention also relates, according to another of its aspects, independently or in combination with the above, to a device for packaging a product, comprising: - A base, having at its periphery a side wall fitted with an internal thread, - a cup fixed on the base, intended to contain the product, - a cover having an external thread, configured to screw into the thread of the side wall of the base.

[0047] The fact that the thread of the base is internal prevents the user from being in contact with the thread when gripping the base, which improves ergonomics. Brief description of the drawings

[0048] The invention may be better understood by reading the detailed description which follows, a non-limiting example of its implementation, and by examining the attached drawing, in which:

[0049] [Fig.l] [Fig.l] shows in elevation an example of a packaging device according to the invention,

[0050] [Fig.2] [Fig.2] represents the device of [Fig.l] after removal of the

[0051] hood,

[0052] [Fig.3] [Fig.3] is a perspective view of the device of [Fig.l] after

[0053] removal of the hood, and

[0054] [Fig.4] [Fig.4] is an axial section of the device of [Fig.l]. Detailed description

[0055] [Fig. 1] shows a packaging device 1 according to the invention, comprising a base 10 and a closing cover 20 fixed to the base 10.

[0056] The base 10 comprises a base 11 which is preferably made of glass, and a mounting part 12, for example made of thermoplastic material, which is fixed to the base 11, for example by gluing, and which comprises a side wall 13.

[0057] The cover 20 has an apparent height Hc, when the device 1 is closed, which is greater than the apparent height Hb of the base 10. For example, we have Hc>1.2 Hb, better Hc>1.4 Hb.

[0058] The base 10 has a rounded lower face with an annular plate 14 allowing the device to rest vertically on a horizontal flat surface.

[0059] The largest external diameter D of the cover 20 is for example greater than its apparent height Hc, or even the total height Hb+Hc of the device.

[0060] The cover 20 may have an apparent lateral surface 21 symmetrical in revolution around the axis X of the device 1, hollowed out towards the inside. The lateral wall 13 of the mounting part 12 of the base 10 may have a curvature which is substantially the same as that of the lateral surface 21, so as to be in continuity with the latter.

[0061] Referring to Figures 2 to 4, it can be seen that the device 1 comprises a cup 30, fixed on the base, which contains a product P to be taken and applied, for example a cosmetic product such as a cream.

[0062] The cup 30 comprises a flared upper part 31 in the shape of a cup, extended downwards by a foot 32 used for fixing the cup to the base 10.

[0063] The foot 32 comprises an outer skirt 33 which surrounds first fixing means 34. The latter comprise, for example, one or more snap-on reliefs 35, for example in the form of a bead, carried by one or more elastically deformable mounting tabs or, as a variant, by an angularly continuous inner skirt.

[0064] The mounting part 12 of the base 10 comprises second fixing means in the form, for example, of an annular lip 15 of axis X, having on its surface

[0065] radially external a recess 16 onto which the relief(s) 35 of the foot of the cup 30 can be snapped.

[0066] The lip 15 connects at the bottom to a flat wall 18 perpendicular to the axis X, defining the bottom of a housing receiving the foot 32 of the cup 30.

[0067] This housing is delimited radially by a substantially cylindrical upright 19 of revolution of axis X, extending over the entire height of the outer skirt 33.

[0068] The upright 19 has a chamfer 40 at its upper end, facilitating the centering and insertion of the foot 32 when mounting the cup 30 on the base 10.

[0069] The side wall 13 is connected to the upright 19 by a wall 41, symmetrical in revolution around the axis X, having a rounded shape in axial section, as shown in [Fig.4], concave upwards.

[0070] The side wall 13 has a thread 43 on its radially inner surface.

[0071] To ensure the centering of the mounting part 12 on the base 11, the latter comprises an annular rib 44 and the side wall 13 has an annular groove 45 in which the rib 44 is inserted.

[0072] The wall 41 can be thinned at its connection to the side wall 13 to form an annular groove 46 in which the lower end 47 of the cover 20 can engage after it has been screwed, as seen in [Fig.4].

[0073] The cover 20 may comprise an external part 22, for example made of metal, in particular aluminum, in which is fixed, for example by gluing, an insert 23 made of thermoplastic material.

[0074] A metal ring 24 forming ballast may be arranged between a mounting skirt 25 of the insert and the outer part 22. The skirt 25 may be connected at the top to a transverse wall 26 extending perpendicular to the axis X.

[0075] This wall 26 may have on its upper face annular ribs 27 and 28 bearing against the inner face of the top of the outer part 22.

[0076] The skirt 25 has an annular bead 27 serving to retain a sealing gasket 50, in the form of a disc, arranged against the lower face of the transverse wall 26.

[0077] In the closed position, the free edge 51 of the cup 30 comes to bear against this seal 50, as illustrated in [Fig.4].

[0078] The skirt 25 comprises a radial rib 52 closing the space between the outer part 22 and the skirt 25, and serving as a lower stop for the ring 24.

[0079] The skirt 25 has under the rib 52 a thread 55 which engages on the thread 43 of the side wall 13.

[0080] When the cover 20 is removed, the cup 30 is visible and provides around it with the base 10 an annular space 60 around the foot 32, under the flared wall 31.

[0081] The height Ha of the visible part of the cup, in side view as in [Fig.2], can represent at least 50% of the total height Ht, better still 60 to 70% of the total height Ht, as illustrated in [Fig.2].

[0082] The side wall 13 has an outer surface that slopes inwardly and upwardly, which may improve the grip of the base 10 when the user places it in the palm of his hand.

[0083] The means for fixing the cup 30 on the base 10 are hidden by the outer skirt 33, which contributes to the aesthetics of the assembly. Similarly, the thread of the wall 13 is not visible when the base 10 is observed in elevation, as in [Fig.2],

[0084] Preferably, the mounting of the cup 30 on the base 10 is such that the cup 30 retains a possibility of rotation around the axis X in the housing defined by the upright 1. This is possible for example due to the shape of revolution of the lip 15. This has an advantage, because the cup 30 can rotate relative to the base 10 at the end of screwing or at the start of unscrewing the cover 20, when the edge 51 presses the seal 50, which limits the wear of the latter.

[0085] When the cup 30 is empty, it can be replaced by separating it from the base 10 by axial traction. The shape of the base 10 and that of the cup 30 facilitates handling during this operation. In particular, the apparent height Ha of the cup 30 makes it easier to grip.

[0086] Of course, the invention is not limited to the example which has just been described.

[0087] For example, the cover 20 can be made with different materials. The same is true of the base 10, the base 11 of which can be made of a material other than glass, for example metal or ceramic.

[0088] The mounting part 12 can be fixed to the base 11 by means other than gluing, for example by crimping or snap-fastening.

[0089] The cup 30 may be fixed to the base 10 in a manner other than by snap-fastening, for example by screwing or by bayonet fixing.

[0090] The cup 30 can be given a less flared, straighter shape, while retaining its external diameter for example.

[0091] The sealing on closure can be achieved otherwise than with a disc-shaped seal, for example with an annular sealing lip formed on the insert of the cover, which engages on the cup.

[0092] The apparent height ratios given above can be retained in variants where the shape of the cup or the base is modified.
