Abstract
Description
[0001] The invention relates to the field of assemblies for packaging and dispensing products, in particular cosmetic products, comprising a container of vial, tube or bottle type containing the product and provided with an opening and a dispensing member intended to block the opening of the container.
[0002] By way of purely non-limiting example, the product may be: a fluid, such as a cosmetic product, or any other fluid product (e.g. food, paint); or a non-fluid product, such as a viscous product (e.g. glue, compost or for example a pasty product designed to flow).
[0003] In particular within the meaning of the present invention, a "cosmetic product" is understood to be a product as defined in Regulation (EC) No 1223 / 2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products.
[0004] More particularly, the present invention relates to dispensing members (also referred to as closure caps) made of synthetic material, which comprise a hollow cylindrical body intended to be snap-fastened to the open end of a container to be closed, and a cover fastened to the body and movable relative to the body between an open position in which the container is open and a closed position in which the container is closed.
[0005] The cover is typically hingedly connected to the body, for example by one or more hinges or joints.
[0006] The cover may also be fastened to the body, for example by being screwed on or by any other means.
[0007] Conventionally, such a dispensing member is fastened to the neck of the container by cooperation between one or more snap-fit fastening protrusions provided on the outer surface of the neck of the container and the inner surface of a fastening skirt, which is provided on the dispensing member and is designed to extend radially around the neck of the container when the closure member is fastened to the position of the neck of the container.
[0008] However, in order to fulfil environmental obligations, it may prove advantageous to be able to disengage the dispensing member from the container in order to reuse it, in particular to be able to refill it, for example with a solid or liquid refill contained in a packaging having a lower plastic content than the container.
[0009] A dispensing assembly comprising a dispensing member comprising a mounting skirt, mounted on a reservoir and intended to be detached from the reservoir using a rotational movement is known from document FR 3 084 655. For this purpose, the neck of the reservoir comprises a radial projection cooperating with a V-shaped ramp formed on the mounting skirt.
[0010] However, this solution is intended for a single detachment operation since, during the relative rotation of the dispensing member with respect to the container, the mounting skirt of the dispensing member and / or the radial projection present on the neck of the reservoir may undergo plastic deformation.
[0011] Therefore, the dispensing member and / or the container will not be reusable.
[0012] Furthermore, the amount of plastic is greatly increased due to the specific shape of the radial protrusions and the mounting skirt.
[0013] The presence of radial projections on the neck of the reservoir and of slopes on the mounting skirt of the dispenser member also makes the structure and design of these elements more complex and increases the difficulty of industrially manufacturing them.
[0014] Finally, the use of such an assembly is not entirely satisfactory in terms of ergonomics and intuitiveness, in particular when reassembling the dispenser member on the container after the two elements have been separated.
[0015] This dispensing assembly does not provide a satisfactory solution to environmental problems and is not simple to design, manufacture and use.
[0016] Containers with non-circular cross-sections are also known, these containers comprising a hollow body with non-circular cross-section and a neck provided with an opening allowing access to the internal volume of the body and connected to said body by a joint or shoulder.
[0017] The junction exhibits an inclined ramp between the body and the neck and this inclined ramp is intended to cooperate with an external skirt of the dispenser member.
[0018] Thus, upon relative rotation of the dispensing member with respect to the container, the outer skirt of the dispensing member cooperates with the inclined profile of the engagement portion to transmit axial forces to the snap-fastening skirt and thereby cause axial disengagement of the snap-fastening skirt from the neck of the container.
[0019] However, also to reduce environmental impact, in order to limit the use of plastics, it is advantageous to reduce the wall thickness of the dispensing member or to reduce the height of its outer skirt, and this necessarily requires reducing the height of the junction between the neck and the body of the container.
[0020] With this design, during relative rotation of the dispensing member with respect to the container, the outer skirt of the dispensing member may deform radially, so that no or insufficient axial disengagement force may be transmitted to the snap-fastening skirt.
[0021] It is therefore an object of the present invention to alleviate the above disadvantages and to improve the reliability of the disengagement of the dispensing member from the container by the relative rotation of these elements.
[0022] Another object of the invention is to reduce the amount of material, in particular plastic, used in particular in the manufacture of the dispenser member but also in the manufacture of the container.
[0023] The present invention relates to an assembly for packaging and dispensing a product, in particular a cosmetic product, comprising a reservoir or container and a dispensing member or cap intended to close the opening of the container.
[0024] The dispensing member is intended to be mounted on the container by snap-fastening and to be disengaged from the container by relative rotation of the dispensing member with respect to the container.
[0025] The container comprises a body, a neck having a circular cross section, and a junction or shoulder having a non-circular cross section which radially connects the body to the neck and has a non-circular cross section.
[0026] The dispensing member comprises a body having a cross section similar or identical in shape to that of the engaging portion of the container and an internal snap-fastening skirt radially surrounded by the body and intended to cooperate with the neck of the container.
[0027] The engaging portion exhibits a slope that slopes towards the neck and that cooperates with the body of the dispensing member during relative rotation of the dispensing member with respect to the container.
[0028] The height of the inclined profile of the engagement portion of the container is dimensioned so as to ensure that upon relative rotation of the dispensing member with respect to the container through an angle of, for example, about 90°, the inner snap-fastening skirt disengages from the neck of the container.
[0029] The dispensing member further comprises at least one reinforcing rib radially connecting the inner snap-fastening skirt to the body of the dispensing member.
[0030] Thus, upon relative rotation of the dispensing member with respect to the container, the body of the dispensing member cooperates with the inclined profile of the engagement portion to transmit an axial force to the inner snap fastening skirt and thereby cause axial disengagement of said inner snap fastening skirt from the neck of the container.
[0031] In other words, the use of reinforcing ribs connecting the body of the dispenser member to the snap-fastening skirt makes it possible to facilitate the transmission from the body to the snap-fastening skirt of this axial force to which the body is subjected during the relative rotation of the dispenser member and the container, due to the cooperation with the inclined profile of the engagement portion of the container. The reliability of the operation of disengaging the dispenser member from the container by the relative rotation of these elements is thus improved.
[0032] Thanks to the reinforcing ribs, the rigidity of the body is increased and any excessive elastic (especially plastic) deformation of said body can therefore be avoided, which deformation could tend to render the disengagement of the dispensing member inoperative by its relative rotation with respect to the container or could even lead to the need to discard the dispensing member.
[0033] Furthermore, the transmission of axial forces experienced by the body to the inner snap-fastening skirt is improved and also allows said inner skirt to be deflected radially outwards, thereby making it easier to disengage said inner skirt from the neck of the container.
[0034] In particular, during relative rotation of the dispensing member with respect to the container, radial forces experienced by the body of the dispensing member are transmitted to the inner snap-fastening skirt so as to promote disengagement thereof by biasing the inner snap-fastening skirt radially outwards.
[0035] Due to the reinforcing ribs, the size of the dispensing member, in particular the wall thickness and therefore the amount of plastic used, can be significantly reduced, while increasing the ease and reliability with which the dispensing member can be disengaged from the container, for example for the purpose of refilling the container, or separating the dispensing member from the container in order to recycle these elements at the end of the life of the packaging and dispensing assembly.
[0036] Finally, the use of such reinforcing ribs also makes it possible to improve the long-term geometric integrity of the dispensing member before being snap-fastened onto the neck of the corresponding container when it is packaged and transported or bulked in large bulk packaging (such as big bags), thereby preventing the dispensing member from deforming individually under the weight of other dispensing members, which deformation would easily hinder the subsequent snap-fastening of the dispensing member onto the neck of the container or even make it impossible.
[0037] For example, the inner snap-fastening skirt has a circular cross-section and radially surrounds the neck of the container.
[0038] Advantageously, the inner snap-fastening skirt comprises at least two skirt portions circumferentially spaced apart by a circumferential gap.
[0039] In other words, the inner snap fastening skirt is discontinuous in the circumferential direction.
[0040] Such a configuration facilitates radial separation of the snap-fastening skirt portions during relative rotation of the dispensing member with respect to the container and makes it possible to further minimize the amount of material required in the manufacture of the dispensing member.
[0041] In a variant, the internal snap-fastening skirt may comprise a body-engagement portion which is continuous in the circumferential direction and at least two skirt portions which are intended to perform a snap-fastening to the neck of the container and which are circumferentially spaced apart by a circumferential gap.
[0042] Advantageously, the dispenser member comprises at least two reinforcing ribs each radially connecting an inner skirt portion to the body of the dispenser member.
[0043] For example, the cross-section of the body of the dispensing member corresponds to the cross-section of the body of the container.
[0044] For example, the non-circular cross-section of the body of the dispensing member has an oval shape defined by a major axis and a minor axis which is at least 10% smaller, preferably at least 15% smaller, in particular at least 20% smaller than the major axis.
[0045] The skirt portion is advantageously centred on the major axis of the non-circular shape of the body of the dispenser member.
[0046] The body may for example further comprise a radially upper wall provided with a flow or dispensing orifice for the passage of the fluid contained in the container.
[0047] Advantageously, the assembly comprises a cover which is hinged relative to the body of the dispensing member by means of at least one joint or hinge about a transverse pivot axis (which transverse pivot axis is along a transverse axis, perpendicular to the height axis of the body) between an open position and a closed position, in which the flow orifice is open and in which the flow orifice is closed, for example by a blocking tip or protrusion.
[0048] Other systems for connecting the lid to the body may be provided. For example, it may be provided that the lid is screwed or snap-fastened to the body. It may also be provided that the dispensing member does not include a pivoting lid, but rather includes a temporary film seal covering the flow orifice or a removable plug that is inserted into the orifice when in position to close the flow orifice and has radial and axial dimensions configured to be removed from the orifice by a user before use of the packaging assembly.
[0049] The hinge is advantageously centred on the minor axis of the cross section of the body of the dispensing member in order to avoid excessive deformation of the hinge when the dispensing member is disengaged from the neck of the container.
[0050] According to an advantageous embodiment, the reinforcement ribs are advantageously provided one on each side of the hinge in the relative position of the dispensing member with respect to the container, as this allows the disengagement of the dispensing member without risk of damaging the hinge.
[0051] More specifically, the reinforcing ribs are advantageously positioned one on each side of the hinge in the circumferential direction and preferably as close to the hinge as possible.
[0052] In case the dispenser member has only one reinforcing rib connecting the snap-fastening skirt to the body of the dispenser member, this rib is advantageously centred on the hinge in the circumferential direction.
[0053] Thanks to the measures mentioned above, the rigidity of the dispenser member is increased, in particular at the hinge, so as to limit any excessive deformation of the hinge and any risk of damage to the hinge during one or more repeated operations of disengaging the dispenser member from the container neck by relative rotation of these elements. Moreover, even when the dispenser member is snap-fastened on the container, the user may see the presence of one or more reinforcing ribs connecting the snap-fastening skirt to the body of the dispenser member; thus, the use of one or more reinforcing ribs in the vicinity of the hinge improves the overall appearance of the dispenser member by turning this or these ribs away from this portion of the dispenser member that directly faces the user.
[0054] According to one embodiment, the dispensing member further comprises an annular sealing lip radially surrounded by the internal snap-fastening skirt and intended to be inserted inside the neck of the container in order to seal the assembly.
[0055] For example, one of the neck of the container and the internal snap-fastening skirt of the dispensing member includes at least a first snap-fastening protrusion, which cooperates with at least a second snap-fastening protrusion arranged on the other of the neck of the container and the internal snap-fastening skirt of the dispensing member.
[0056] The first snap-fastening convex-concave portion and the second snap-fastening convex-concave portion may be protruding or concave.
[0057] According to one embodiment, each skirt portion comprises at least one snap-fastening projection projecting radially towards the neck of the container and intended to cooperate with an annular rib provided on said neck.
[0058] According to one embodiment, the snap fastening projections extend circumferentially over the entire circumference of the corresponding skirt portion.
[0059] The invention will be better understood by studying the detailed description of an embodiment given by way of purely non-limiting example and illustrated in the accompanying drawings, in which:

[0082] In the remainder of this description, reference will be made to the orthogonal system X, Y, Z, where Z corresponds to the axis of elongation representing the vertical direction, and where it is found that:
[0083] - a longitudinal axis X, which is horizontal and Figure 2 The middle extends from back to front;
[0084] - a transverse axis Y which is horizontal, perpendicular to the longitudinal axis X and Figure 2 extends from left to right in the middle; and
[0085] - a vertical axis Z which is orthogonal to the longitudinal axis X and the transverse axis Y and is Figure 1 Extends from bottom to top.
[0086] The expressions “upper” and “lower” refer to an upper portion and a lower portion of the drawings in an assembled position of components.
[0087] Figure 1 An assembly 1 for packaging and dispensing a product, in particular a cosmetic product, is shown.
[0088] A "product" is understood to be a liquid, semi-liquid or viscous product intended to flow from a reservoir under the effect of gravity. In a completely non-limiting manner, the product may be a cosmetic product, such as a hygiene product or a care product.
[0089] The assembly 1 for packaging and dispensing a product comprises a reservoir or container 10 and a dispensing member 20 or cap intended to close the opening of the container 10 .
[0090] The container 10 comprises a hollow body 11 defining an internal volume 12 containing the product. The container 10 extends axially along an axis ZZ' assumed vertical in the figures from an upper end 13 forming a neck provided with an opening 13a for accessing the internal volume 12 to a lower end 14 forming the bottom of the reservoir.
[0091] The container 10 may be made of, for example, a rigid synthetic material.
[0092] In this case, the outer diameter of the neck 13 is smaller than the outer diameter of the body 11 of the container 10 .
[0093] As illustrated, in this case, the body 11 of the container 10 has a non-circular cross section and the neck 13 has a circular cross section. In a variant, the body 11 of the container 10 may have a circular cross section or a cross section of any other shape.
[0094] The neck 13 is connected to the body 11 of the container 10 by means of a joint or shoulder 15. In this case, the joint 15 exhibits an inclined slope 15a between the body 11 and the neck 13.
[0095] The container 10 includes a shoulder 11a (at the bottom) that connects the inclined surface 15a of the engaging portion 15 to the body 11 of the container 10. Figure 3 and Fig.10Such a shoulder 11a makes it possible to create an abutment against which the lower end 21a of the body 21 of the dispensing member 20 can abut when the dispensing member 20 is mounted on the container 10.
[0096] As a variant, provision can be made such that no such shoulder is present.
[0097] The joining section 15 likewise has a non-circular cross section.
[0098] The non-circular cross section has an oval shape defined by a major axis A1 and a minor axis A2 which is at least 20% smaller than the major axis A1. Figure 2 is visible in.
[0099] As in Figure 2 As can be seen in detail in FIG. 1 , the neck 13 comprises, on its outer surface 13 b , a rib 13 c , in this case an annular rib, intended to cooperate with an internal snap-fastening skirt 25 of the dispenser member 20 .
[0100] For example, the dispensing member 20 is produced in one piece by injection molding of a plastic material, for example a polymer like polypropylene, or any other polymer composition having similar physical properties.
[0101] like Figures 4 to 11 As illustrated, the dispensing member 20 comprises a body 21 of non-circular cross section extending along a longitudinal axis ZZ' (depicted in this case in a vertical use position) and comprising an open lower end 21a intended to surround the annular neck of the container 10 and to come into axial contact with the engagement portion 15 of the container 10. The dispensing member 20 further comprises an upper end 21b opposite the lower end 21a.
[0102] The cross section of the body 21 corresponds to the cross section of the body 11 of the container 10. Thus, in this case, the non-circular cross section of the body 21 of the dispensing member 20 has an oval shape defined by a major axis A'1 and a minor axis A'2 that is at least 20% smaller than the major axis A'1. Figure 7 In this case, the axes A′1 , A′2 are parallel to the axes A1 , A2 of the engagement portion 15 of the container 10 .
[0103] The body 21 further comprises a radially upper wall 22 , in this case substantially planar, closing the upper end 21 b and provided with a flow orifice 22 a for the passage of the fluid contained in the container 10 .
[0104] As illustrated, the upper wall 22 is set back axially from the upper end 21b of the body 21. As a variant, it may be provided that the upper wall 22 is axially aligned with the upper end 21b.
[0105] In the exemplary embodiment illustrated, the flow orifice 22a opens out into a boss protruding from the upper wall 22. As a variant, provision may be made for the flow orifice 22a to open out into a planar upper wall.
[0106] The dispensing member 20 further comprises a cover 23 which is pivotable relative to the body 21 about a transverse pivot axis A0 by means of a joint or hinge 24. Figure 1 , Figure 4 and Figure 5 The visible open position is the same as Figure 7 The hinged portion is hinged between the closed position visible in the figure, the transverse pivot axis being along the transverse axis Y, perpendicular to the longitudinal axis Z.
[0107] The cover 23 may be connected to the body 21 , for example, by a hinge of the “membrane” or living hinge type, or a strip having reduced thickness at the pivot axis A0 , so as to impart bending properties to the hinge.
[0108] In this case, the hinge 24 is centred on the minor axis A2 of the cross section of the body 21 of the dispensing member 10 .
[0109] Other systems for connecting the lid 23 to the body 21 may be provided. For example, it may be provided that the lid 23 is screwed or snap-fastened to the body 21. It may also be provided that the dispensing member 20 does not include a pivoting lid 23, but rather includes a temporary film seal or a removable plug covering the dispensing orifice 22a, which is inserted into the orifice when in a position to close the dispensing orifice and has radial and axial dimensions configured to be removed from the orifice by a user before using the packaging assembly.
[0110] As shown, the cover 23 has a profile 23a closed by a wall or top surface 23b. The profile 23a corresponds in shape to the upper wall 22 of the body 21. The cover 23 further comprises a plug member 29 which protrudes axially from the inner surface of the top surface 23b towards the interior when the cover 23 is in the closed position. In this case, the plug member 29 is produced in the form of a column.
[0111] Figure 1 The open position shown in FIG. 2 corresponds to a position where the flow aperture 22 a is opened to allow the fluid contained in the container 10 to flow toward the outside. Figure 7 The closed position shown in FIG. 2 corresponds to a position in which the flow aperture 22 a is closed, being closed by the stopper member 29 , thereby preventing the fluid contained in the container 10 from flowing toward the outside.
[0112] The dispensing member 20 further comprises an internal snap-fastening skirt 25 , of circular cross-section, radially surrounded by the body 21 and intended to radially surround the neck 13 of the container 10 .
[0113] In the non-limiting example illustrated, the inner snap-fastening skirt 25 comprises two skirt portions 25a, 25b circumferentially spaced apart by a circumferential gap. In other words, the inner snap-fastening skirt 25 is discontinuous in the circumferential direction.
[0114] Advantageously, the skirt portions 25 a , 25 b are centred on the major axis A′ 1 of the non-circular shape of the body 21 of the dispenser member 20 .
[0115] Each skirt portion 25 a , 25 b comprises a snap-fastening projection 26 a , 26 b projecting radially towards the neck 13 of the container 10 and intended to cooperate with the annular rib 13 c of said neck 13 .
[0116] In this case, the snap-fastening projections 26a, 26b extend circumferentially over the entire circumference of the respective skirt portion 25a, 25b.
[0117] As a variant, provision may be made for each skirt portion 25a, 25b to comprise a snap-fastening groove and for the neck 13 to comprise an annular snap-fastening projection co-operating with said groove.
[0118] Generally speaking, one of the neck 13 of the container 10 and the internal snap-fastening skirt 25 of the dispensing member 20 includes at least a first snap-fastening protrusion that cooperates with at least a second snap-fastening protrusion provided on the other of the neck 13 of the container 10 and the internal snap-fastening skirt 25 of the dispensing member 20. The first snap-fastening protrusion and the second snap-fastening protrusion may be protruding or recessed.
[0119] As illustrated, the dispensing member 20 further comprises an annular sealing lip 27 radially surrounded by the internal snap-fastening skirt 25 and intended to be inserted inside the opening 13a of the neck 13 of the container 10 so as to seal the assembly 1 .
[0120] As illustrated and purely non-limitingly, the dispenser member 20 further comprises two reinforcing ribs 28 a , 28 b which each radially connect one inner skirt portion 25 a , 25 b to the body 21 of the dispenser member 20 .
[0121] As a variant, it is possible to provide only one internal snap-fastening skirt portion 25 and only one reinforcing rib 28 radially connecting said internal snap-fastening skirt 25 to the body 21 of the dispenser member 20 .
[0122] The reinforcing ribs 28a, 28b are advantageously provided one on each side of the hinge 24 in the relative position of the dispensing member 20 with respect to the container 10, as this allows the disengagement of the dispensing member 20 without risk of damaging said hinge 24.
[0123] More specifically, the reinforcing ribs 28a, 28b are advantageously positioned one on each side of the hinge 24 in the circumferential direction and preferably as close to the hinge as possible.
[0124] In the embodiment in which the dispenser member has only one reinforcing rib connecting the snap-fastening skirt to the body of the dispenser member, this rib is advantageously centred on the hinge in the circumferential direction.
[0125] As in Figure 7 As can be seen in FIG. 1 , each rib 28a, 28b makes an angle α with the minor axis A2. The angle α is for example comprised between 30° and 50°, for example between 40° and 45°, and for example is about 42°.
[0126] In the position where the dispensing member 20 is assembled on the container 10, as shown Fig.10 As can be seen in FIG. 2 , the lower end 21 a of the body 21 of the dispensing member 20 abuts axially against the shoulder 11 a of the container 10 .
[0127] The height H1 of the inclined slope 15a of the engagement portion 15 is at least equal to the stroke C1 required for the snap-fastening projections 26a, 26b of the corresponding snap-fastening skirts 25a, 25b to disengage.
[0128] The stroke C1 extends axially between the lower surfaces of the snap-fastening projections 26 a , 26 b and the upper surface of the annular rib 13 c of the container neck 13 .
[0129] Therefore, the height H1 of the inclined slope 15a of the engaging portion 15 of the container 10 is dimensioned to ensure that the inner snap-fastening skirts 25a, 25b are disengaged from the neck 13 of the container 10 when the dispensing member 20 is relatively rotated relative to the container 10, for example by an angle of about 90°.
[0130] The first stroke C1 is, for example, between 1 mm and 3 mm, for example between 1.5 mm and 2.5 mm, for example equal to 1.95 mm.
[0131] The height H1 is at least equal to the stroke C1, preferably at least equal to 1.5 times the stroke C1. For example, when the stroke C1 is equal to 1.95 mm, the height H1 is equal to 3.3 mm.
[0132] When the dispensing member 20 rotates relative to the container 10, the body 21 of the dispensing member 20 cooperates with the inclined profile 15a of the engaging portion 15 (eg, Fig.11 ) to transmit axial force to the internal snap-fastening skirt 25 and thereby cause axial disengagement of the internal snap-fastening skirt 25 from the neck 13 of the container 10.
[0133] The use of reinforcing ribs 28a, 28b connecting the body 21 of the dispensing member to the snap-fastening skirt 25 makes it possible to facilitate the transmission of this axial force to which the body 21 is subjected during the relative rotation of the dispensing member 20 and the container 10 due to the cooperation with the inclined profile 15a of the engagement portion 15 of the container 10, from the body 21 to the snap-fastening skirt 25. The reliability of the operation of disengaging the dispensing member 20 from the container 10 by the relative rotation of these elements is thus improved.
[0134] The container 10 is made of a plastic material, such as polypropylene (PP), PET, recyclable PET or high-density polyethylene (HDPE).
[0135] The dispensing member 20 is made of a plastic material, such as polypropylene (PP) or high density polyethylene (HDPE).
[0136] Due to the reinforcing ribs 28a, 28b, the rigidity of the body 21 is improved and thus any plastic deformation of said body can be avoided.
[0137] Furthermore, the transmission of axial forces experienced by the body 21 to the internal snap-fastening skirt 25 is improved and also allows said internal skirt 25 to deflect radially outwards, making it easier to disengage said internal skirt 25 from the neck 13 of the container 10 .
[0138] Due to the reinforcing ribs 28a, 28b, the size and wall thickness of the dispensing member 20 and therefore the amount of plastic used can be significantly reduced, while the ease with which it can be disengaged is improved, for example for the purpose of refilling the container 10, or separating the dispensing member from the container in order to recover the product at the end of its life.
