Description

Technical Field of the Invention

The present invention is in the field of receptacles for the packaging of food sensitive to their venting, and more particularly stackable receptacles by stacking. It relates to a modular container composed of several modules stacked and successively assembled to each other.

State of the art

The packaging of food sensitive to their venting is made difficult because of this sensitivity. Such foods are likely to be foodstuffs, such as a gaseous liquid, or cosmetic and / or therapeutic products for example. These foods are often contained inside a hermetically sealed container that keeps them until they are consumed. Such containers are in particular formed by molding a plastic material, such as by blow molding or similar molding technique. However, the consumption of food after opening the container may be spread over time, with the consequence of a risk of deterioration of the food contained inside the container until the latter.

Therefore, modular containers have been proposed composed of several similar elementary containers assembled successively to each other by stacking. Such a modular container is generally of cylindrical overall conformation, the elementary containers which compose it comprise a recessed bottom of conical conformation in particular, for the reception by fitting of a complementary shaped neck of an adjacent container. The assembly of the elementary receptacles two by two is for example made by means of a flange, by means of screwing means equipping the end of their neck, or through cooperating interlocking members respectively formed in the bottom and on the neck of the elementary containers. In particular, we can refer to the documents EP1321370 (PICI A.), WO02 / 12077 (RAMJAN, RAMAN), DE10232578 (CANAK M.), WO0236444 (NICHE EDGE Ltd), GB2303114 (JONATHAN DEREK & ROBINSON ) FR818908 (VEREINIGTE LAUSITZER GLASWERKE AKTIENGESELLSCHAFT) who describe such modular containers.

A difficulty to overcome lies in a quick and reliable assembly of the elementary containers together. Indeed, the assembly methods must be easy to implement not to constitute a prohibitive constraint for the consumer, while being sufficiently robust to make this assembly reliable. In addition, these assembly methods must be carried out taking into account the manufacturing constraints by molding the elementary containers, and avoiding to induce their bulk, therefore likely to undermine the desired contact of the wall of the necks. against that of funds. Finally, this assembly must guarantee the centering and the successive prolongation rigorously aligned elementary receptacles, without risk of deviation from one elementary container to another may be induced under the effect of the efforts provided by the consumer to achieve this assembly, in order to keep the modular container a continuous aesthetic line.

It was specifically proposed by EP1321370 to provide the elementary receptacles complementary interlocking reliefs which extend at the periphery respectively of their neck and their bottom. The interlocking reliefs are of annular conformation and their cooperation is carried out by axial thrust operated by the user. Such axial thrust causes radial deformation of the peripheral wall of the containers to allow the axial passage of one of the reliefs within the other relief. According to a variant, the interlocking reliefs are shaped in a circular arc by being arranged as a junction device of the bayonet type.

Such provisions do not provide satisfactory ergonomics because of the efforts that must deploy the user to assemble the elementary containers together, and / or actions that must perform the user to assemble and separate the elementary containers. In addition, the methods used for the assembly of the elementary containers do not provide a firmness able to give the container a satisfactory overall strength, especially in the case of use of a device bayonet type. Moreover, the assembly methods used induce significant tensions on the walls of the elementary containers, which are detrimental to the durability of the container and more particularly to that of the elementary containers that compose it. These voltages hinder the guarantee of a rigorous centering of the elementary containers relative to each other, and consequently alter the aesthetic line of the container. These voltages are also troublesome to the ease of handling the elementary containers for their assembly to each other. The ergonomics of the container is ultimately dissuasive for the user, either because of the feeling of fragility of the container, the walls of the elementary containers must be sufficiently malleable to allow their deformation, or because of the consequent axial forces that must exert the user against the deformation of the wall of revolution of the elementary containers, in this robust case. If the variant consisting in using a device of the bayonet type is likely to reinforce the assembly of the elementary receptacles with each other, it requires a clearance to limit the stresses associated with their assembly, which is not satisfactory with regard to the floating result between the elementary receptacles thus assembled.

Object of the invention

The object of the present invention is to provide a modular container composed of a plurality of elementary containers stacked successively in extension of each other, which offers a satisfactory solution in view of the difficulties that have been stated. It is particularly targeted by the the present invention to allow assembly and separation of the elementary containers between them which is ergonomic and which limit the tensions exerted on the revolution wall of the elementary containers, while ensuring the reliability of the assembly obtained, the durability of the container both structural and 'Regarding the conservation of its overall aesthetic line, and this despite repeated operations of assembly and separation of the desired elementary receptacles potentially the most numerous possible. It is also within the scope of the present invention to propose such a container, the advantages of which do not affect its competitiveness, in particular by enabling it to be obtained at lower cost.

The modular container of the present invention is composed of a plurality of elementary containers stacked successively in extension of each other. The elementary containers comprise a recessed bottom of a conformation of revolution to receive a neck of a similar conformation. Cooperating interlocking members are respectively formed at the bottom and on the neck of the elementary receptacles, to constitute means for assembling the elementary receptacles together.

According to the present invention, such a modular container is mainly recognizable in that the interlocking members associate cooperating peripheral ramps by interlocking, which are able to assemble the elementary receptacles between them by rotation for their axial junction, and end stops. stroke of this rotation cooperating by clipping, which constitute means for locking the assembly in rotation of the elementary receptacles together and which are able to prohibit spontaneous reverse rotation.

The assembly means associates axial engagement means of the elementary receptacles, which are constituted by the ramps, and radial engagement means of the elementary receptacles by elastic deformation, which are constituted by the abutments. These stops are put in cooperation by clipping at the end of the rotary stroke elementary containers relative to each other to lock the assembly obtained by the axial interlocking means. These arrangements are such that the assembly of the elementary containers is able to be obtained from a freely rotating movement free of stresses on them and in particular on their wall with a view to their axial joining. Such a movement is easily achieved by the user without effort likely to generate tension on the revolution wall of the elementary containers. Such absence of tension preserves the container and ensures an ideal centering of the elementary containers relative to each other, and therefore guarantees the obtaining and preservation of the aesthetic line of the nodular container. The rotational movement providing a centering and axial junction of the elementary containers is completed by clipping them to each other through the stops, to lock their axial junction and prohibit their spontaneous separation by reverse rotation. The surfaces of the abutments placed in cooperation by clipping are likely to be limited and freely arranged independently of the axial joining arrangements by rotation of the elementary containers, which allows to adapt them according to the desired forces to be deployed by the user for the assembly containers, and / or according to the desired strength of the walls of the elementary containers. It follows that the designers can easily adapt the conformation and / or the robustness of the stops independently of the robustness of the revolution wall of the elementary containers.

Preferably, the stops are integrated with the ramps and cooperate with each other by clipping in response to an elastic deformation of the interlocking members. These provisions are such that the engagement of the elementary receptacles by clipping results from an elastic deformation of the interlocking members, preserving the wall of revolution of the elementary receptacles which is excluded from such elastic deformation. It follows that the wall of revolution of the elementary containers is able to be robust because of the necessary absence of its deformation, its resistance to deformation being independent of the assembly of the elementary containers together.

More particularly, the interlocking members are elastically deformable by means of the ramp and / or the abutment which they integrate respectively, so as to reduce as much as possible the tensions exerted on the revolution wall of the elementary containers during of their assembly or conversely their separation.

The ramps are respectively hollowed out and / or projecting indifferently on one and / or the other of the bottom and / or the neck of the elementary containers.

The abutments are respectively recessed and / or projecting indifferently on one and / or the other of the ramps respectively assigned to the bottom and / or the neck of the elementary receptacles. The cooperation surface between the stops is advantageously spherical or similar.

The abutments are of restricted surface with respect to the totality of the contact surface between two assembled elementary receptacles. The arrangement of the cooperation of the abutments by means of spherical bearing surfaces is for example obtained from a conformation of the abutments respectively spherical cap and cup or similarly cylinder or equivalent. Such a spherical bearing gives the abutments a cam arrangement capable of progressively provoking the elastic deformation exploited for locking the assembly of the elementary receptacles together. It shows a comfort of handling for the user and a limitation of the tensions likely to be induced on the revolution wall of the elementary containers.

Overall, the interlocking members combine at least one male interlocking member and / or at least one female interlocking member which are indifferently respectively formed at the bottom and the neck. The interlocking members and the elementary container which integrates them are advantageously monoblock molding, the interlocking members being advantageously integrated molding the elementary container or in a single operation of molding by overmolding. The molding operations are for example injection molding or blow molding operations. One advantage of forming the abutments by overmoulding lies in the easy dissociation between the respective constituent materials of the elementary container and the abutments that it incorporates. Such a dissociation makes it possible to adapt, from the choice of the appropriate material, the robustness of the wall of revolution of the elementary receptacles and the malleability of the abutments in order to facilitate the ease of clipping while conferring on the latter sufficient strength to obtain the locking the assembly obtained between the elementary containers.

In the case of an operation of several interlocking members and / or of several ramps and stops incorporated in one of these interlocking members, the respective male and female arrangement of the interlocking members, ramps and / or or stops are to be considered in isolation. The female interlocking member is preferably arranged on the bottom to form a recess for receiving the male interlocking member which is formed on the neck, without this distribution prejudging the male or female character of the ramp or ramps. and the stop or stops respectively integrated with the interlocking members. More particularly, the male and female interlocking members may be respectively provided with one or more ramps and abutments which are indifferently protruding and recessed not only from one to the other of the interlocking members. but also to each other for the same interlocking member.

More specifically, at least one male interlocking member is provided projecting on the neck and incorporates in its edge at least one ramp and at least one stop, while at least one female interlocking member is formed of a hollow receiving the projection being formed on the bottom, and comprises at the periphery at least one complementary ramp and at least one complementary stop which are cooperating respectively with the ramp and with the stop. The cooperating ramps are indifferently respectively arranged in female reception ramp of the other male ramp. The cooperating abutments are indifferently respectively arranged in receiving female stop of the other male stop. These male and female arrangements ramps, or even stops, are preferably accumulated for the same ramp or the same abutment.

The interlocking members and the elementary container which integrates them are advantageously monobloc by being jointly formed by molding. The abutments may be indifferently formed by molding together with the interlocking members and / or be reported on the latter, by gluing, welding, overmolding or other similar fastening technique. It is, however, preferred to form the interlocking members, consisting of the boom and abutment, together by molding with the vessel for production gains.

The cooperating abutments are constituted by complementary clipping reliefs which are indifferently formed at the end of the ramps for a tangential connection of the elementary receptacles with respect to their conformation of revolution, and / or by clipping reliefs formed on the indifferently axial faces. and / or peripheral interlocking members, including ramps, for a radial connection of the elementary receptacles together.

According to a first variant of embodiment, a male interlocking member is constituted by an integrated molding plate at the bottom or preferably at the neck. This plate comprises a plurality of radially evenly distributed ramps of which at least one, and preferably all, integrates at least one stop. A female interlocking member is constituted by a recess of complementary shape of inversely integrated molding at the neck or at the bottom.

The ramps are for example arranged in grooves in the edge of the plate, whose projecting edges and the median recess together constitute a ramp.

The cooperating abutments are preferably respectively arranged in cap and cup and are indifferently axial extension, being provided on the shoulders respectively formed by the plate and the recess, and / or radially extended by being provided on the respective slices respectively platinum and the recess, and more particularly on the slices of the corresponding ramps, especially bottom bleed. More particularly, the stops are arranged, alone or in combination, on the axial faces or on the peripheral faces of the ramps.

The ramps are indifferently circular or helical extension, but preferably are helically shaped and constitute axial thrust members against the stops. More particularly, the ramps are indifferently circular or helical extension. However, it is preferred to conform the helical ramps so that they constitute axial thrust members against the stops. The ramps are capable of gradually pushing the abutments arranged in axial clipping relief during the relative rotation between the elementary containers. Such a progressive compression contributes to preserving the walls of the elementary receptacles, and promotes the spontaneous cooperation of the stops at the end of the rotational stroke of the elementary receptacles relative to one another. In addition, the user exerts a progressive effort of rotation on the elementary containers until locking their assembly, which improves the ergonomics of the container.

According to a second variant embodiment, the ramps are in plurality being radially evenly distributed and being oriented along a generatrix of said conformation of revolution of the recess of the bottom and the neck. The interlocking members are mainly oriented along this generatrix, and are capable of extending totally or partially along this generatrix, preferably in a continuous manner without excluding an embodiment according to which the interlocking members are discontinuously extended in sections. The interlocking members, and more particularly the ramps, comprise respective cooperating abutments which extend tangentially to said conformation of revolution.

The cooperating abutments are for example constituted by at least one bead and a groove which are respectively formed at the end of one and / or the other of the respective ramps assigned to the bottom and the neck. This bead and this groove are in particular of cylindrical conformation for their co-operation of the type similar to a spherical bearing. The surfaces of revolution of the bead and groove extend over a range greater than 180 ° to obtain their cooperation by shifting. The cooperating stops being formed at the periphery of the bottom and the neck, the extension axes of the bead and the groove are parallel and radially eccentric with respect to the axis of revolution of the bottom and the neck.

Note that the conformation of the outer surface of the modular container, except that of the zone of revolution that includes the neck and which cooperates with the bottom, is likely to be any such as polygonal and / or circular.

Preferred but non-limiting applications of the modular container of the invention reside in the packaging of foodstuffs, cosmetics and / or therapeutic for example, or any other perishable food in particular. Such foods are likely to be indifferently liquids, gaseous and / or volatile or not, solids, still powdered and / or gelled and / or pasty state, powders, powder, creams or similar goods.

The goods contained respectively in the elementary receptacles are likely to be identical or different commodities from one elementary container to another. In the case of different foods, these are likely to be products intended to be mixed extemporaneously to their use for example, or to be products of the same nature but having different characteristics, such as color and / or state and / or texture for example.

The present invention will be better understood, and details will arise from the description that will be made of variants in connection with the figures of the attached plates, wherein:

• The fig.10 is a top view of the basic container shown on the fig.9 .

In the figures, a modular container is composed of a plurality of elementary receptacles 1 nested axially successively in each other. The number of three elementary receptacles 1 as illustrated is not limiting as to the scope of the present invention, this number of elementary receptacles 1 may be at least two. These elementary containers 1 are similar and are advantageously obtained by molding from the same mold. Each elementary container 1 comprises a neck 2, in particular designed to be provided with a removable cap 3 as illustrated in FIG. fig.3 . The neck 2 comprises a generally cylindrical zone, which is extended by a conical zone. The bottom 4 of the elementary container is hollowed out, this recess 5 having a shape complementary to that of the neck 2 to allow the nesting in extension of each other of a plurality of elementary containers 1 to obtain the modular container of the invention.

The conical areas of the neck 2 and the bottom 4 comprise respective cooperating interlocking members 6 and 7. These interlocking members 6,7 each associate at least one 8.9 ramp and a stop 10, 11 cooperating with a ramp 8 , 9 and a stop 10,11 complementary to a neighboring elementary container 1. The abutments 10, 11 are elastically deformable to constitute means for locking the assembly of the elementary receptacles 1 with each other. The axial assembly between elementary containers 1 is obtained from their relative rotation by placing the ramps 8,9 in cooperation with each other. The stroke of this rotation is limited by stops 10, 11, which cooperate with each other by clipping to lock the axial assembly of the elementary receptacles 1, prohibiting their spontaneous reverse relative rotation.

More particularly, the assembly, and by analogy inversely, the separation of the elementary receptacles 1 are respectively obtained from a relative rotary movement of the elementary receptacles 1. Such a movement, simple to perform for the user, provides in a first step an axial assembly of the elementary containers 1 and in a second step and without breaking this gesture, the locking of this assembly. The locking and unlocking of the assembly of the elementary containers 1 are obtained from respective gestures which are of a limited extent and which generate limited efforts for the user. These efforts being limited, the elementary containers 1 are preserved, their relative centering is favored during assembly, and the ergonomics of the modular container is optimized by providing a comfortable handling for the user. The assembly of the containers elementary 1 is obtained from a relative rotation of the elementary containers 1 quickly and reliably regardless of the effort provided by the user. The individual locking of this assembly is free of forces that may alter the conformation and / or alignment of the elementary containers 1 relative to each other, and / or may weaken or even deteriorate.

According to a first embodiment variant illustrated on the fig.1 to fig.5 , the interlocking members 6, 7 are in a plurality being radially equispaced at the periphery respectively of the bottom 4 and the neck 2. These interlocking members 6,7 each include a ramp 8,9 and a stop 10,11, and extend in a global orientation corresponding to a generatrix conical areas of the bottom 4 and the neck 2. It will be understood that this extension is to be understood in the geometric sense of the term, these interlocking members 6.7 having a width extending on an angular beach. On the fig.5 more particularly, the interlocking members 6.7 are at least three in number for each of the bottom 4 and the neck 2, distributed at 120 ° so as to consolidate the centering of the elementary receptacles 1 between them. The interlocking members 6 of the neck 2 are placed in partial superposition of the interlocking members 7 of the bottom 4. Referring also to the fig.4 , this partial superposition aims to allow axial introduction of the neck 2 of an elementary container 1 inside the bottom 4 of another elementary container 1 'without having to provide effort for their interlocking one in the other, then to assemble the elementary receptacles 1,1 'between them by picking from a cooperation between the ramps 8,9 which are respectively provided on the interlocking members 6,7 of the neck 2 and bottom 4.

On the fig.4 , the ramps 8,9 which are shaped for one 9 in a recess in the bottom 4 of the elementary container 1 and opening towards the base thereof, and for the other 8 in a projection formed on the conical zone of the neck 2 of the other elementary container 1 '. The ramp 8 that includes the interlocking member 6 projecting fitted to the neck 2 is in particular shaped in tongue, while the other ramp 9 that includes the interlocking member 7 recessed equipping the bottom 4 is shaped in groove formed in the thickness of the bottom 4. The interlocking members 6,7 each extend over an angular range P1 of the order between 50 ° and 70 °, and more particularly over a range of 60 °. Ramps 8, 9 extend more particularly over an angular range P2 of the order of between 15 ° and 25 °, and more particularly over a range of 21 °. The angular range P3 superposition of the interlocking members 6.7 between those of the neck 2 and those of the bottom 4 is in turn of the order of 40 °. Note that this encrypted information is indicative without being limiting as to the scope of the present invention.

The stops 10, 11 are formed at the end of the ramps 8, 9 to lock the axial assembly obtained by the cooperation by hooking of the ramps 8,9 therebetween. This position of the stops 10, 11 offers a clipping lock from their elastic deformation. One of the abutments 10 is shaped as a bead formed at the end of the tongue 6, and the other of the abutments 11 is shaped as a groove formed at the bottom of the blind groove 9, for receiving the corresponding bead 10. To assemble two elementary receptacles 1, 1 'to each other for the formation of the modular container of the invention, the neck 2 of one of the elementary containers 1' is introduced by sliding inside the bottom 4 of the other elementary container 1. It will be noted that the interlocking members 6.7 extending in a similar angular range, the axial introduction of the neck 2 into the bottom 4 is radially guided and requires no effort. Then at least one of the elementary containers 1 and / or 1 'is manipulated in rotation for the passage of the tongues 8 inside the corresponding grooves 9. This operation is carried out again without any particular effort. Finally, at the end of the rotary stroke of the elementary container 1 and / or 1 ', a greater pressure thrust exerted by the user causes the clipping of the stops 10,11 between them, thus locking the assembly by interlocking between the two containers elementary 1,1 '. To separate the elementary receptacles 1,1 'from each other, it suffices to operate inversely the aforementioned maneuvers.

According to a second embodiment variant illustrated on the fig.6 to fig.10 , the interlocking members 6, 7 are shaped as platinum 12 for the protruding member 6 formed on the neck 2, and as recess 13 of complementary shape for the recess 7 in the bottom 4 of the elementary receptacles 1. The plate 12 comprises three ramps 8 radially equal parts which are formed in its edge so as to extend at the periphery of the corresponding interlocking member 6. The recess 13 comprises corresponding ramps 9 of complementary shape. Each ramp has a stop 10,11 whose depth is oriented axially. Stops 10 arranged in spherical cap are provided projecting axially to the upper face of the plate 12, while abutments 11 arranged in a cup are hollowed out in the recess 13.

More particularly on the embodiment illustrated on the fig.9 and fig.10 , the ramps 8, 9 are furthermore provided with abutments 14, 15 of complementary shape whose depth is oriented radially.

The arrangement of the interlocking members allows their easy operation to advantageously cause a progressive elastic deformation of the interlocking members, and a spontaneous locking of the assembly from the release of the interlocking members without the user has to provide a specific effort to obtain the lock. More particularly on the embodiment illustrated on the fig.6 to fig.8 , the upper face of the plate 12 delimits front ramps 16 which are inclined relative to the axis of the elementary container 1, to form a propeller capable of inducing a thrust against the stops 10,11 during the assembly movement by rotation between two elementary receptacles 1.
