Description

"DEVICE FOR PACKAGING AND DISPENSING A PRODUCT THAT HAS AN INTEGRATED COLLECTION MEMBER"

[0001] The present invention relates to the general field of testing devices used with a conditioning and dispensing device to test a liquid product or semi-liquid product such as a cosmetic product such as a hair care product and more particularly for a care product with hair as hair serum, hair color, hair oil, hair cream or for product used for washing such as body wash or for skin care product such as body or face cream, cleanser or hair care product product used for hair care or skin care or a mixture before applying the entire product, the container having a plurality of comb teeth designed to apply a product to a surface.

[0002] The expression "cosmetic product" is understood to mean a product as defined in Article 2 of Regulation No. 1223/2009 of the European Parliament and of the Council of November 30, 2009.

[0003] Generally, in view of testing a product or a mixture before applying the entire product, for example, in order to detect a potential user allergy to this product or mixture, it is known to use a cotton swab or adding a distinct sample member.

[0004] Reference may be made to document No. U.S. 2007/0180895 - A1 which describes a packaging system having a container and a testing device that is shaped like a cotton swab.

[0005] However, such solutions for sampling a part of a product to be tested are not efficient.

[0006] An advantageous application of the invention is the use of the container to package cosmetic products, such as cosmetic products to dye human keratin fibers. Other advantageous applications of the invention may be the use of the container to store care products, adhesive products, polymeric coatings, flavored liquids, etc.

[0007] An objective of the present invention is to provide a device to package at least one product of simple structure, easy to manufacture and which has an integrated sampling member.

[0008] The purpose of the present invention is to provide a device for conditioning at least one product and dispensing at least said product on a surface, for example, hair. Said device comprises at least one container delimiting a product cavity containing said at least one product and a closure configured to close a first dispensing port of the container in flow communication with the product cavity.

[0009] Said closure is provided with a collecting portion configured to collect a part of the product contained in the product cavity.

[0010] Therefore, there is no need to add a separate collection member or use a cotton swab to test the product prior to first use. The product can be collected and tested directly by closing the device.

[0011] Advantageously, the closure has a suitable closure member for closing the dispensing orifice of the container.

[0012] Said closure member may be tubular or may have any other suitable shape to close said dispensing orifice.

[0013] For example, the closing member comprises the collection portion.

[0014] The collection portion may be formed on said closing member.

[0015] For example, the collection portion is made through the thickness of the closure member.

[0016] In one embodiment, the closure member comprises a gripping member designed to cooperate with a complementary gripping member provided on the inner surface of the dispensing hole.

[0017] The gripping element may be a quarter turn.

[0018] Alternatively, any other fastening element can be used to temporarily secure the dispensing closure in the dispensing hole, such as a screw thread, a clipping mechanism, a snap-in system, etc...

[0019] The collection portion, for example, is at least one hole provided in the closure member, in a proximity to its free end.

[0020] The hole may be a through hole made through the thickness of the closure member.

[0021] It is also possible to provide a plurality of holes or through holes made in the closure member.

[0022] The hole can have a rectangular shape, a circular shape, a triangular shape or any other suitable shape to collect a part of the product contained in the cavity.

[0023] The hole allows to collect a part of the product contained in the container. The user can then test said collected part before using the entire product.

[0024] In another embodiment, the collection portion comprises at least one axial groove.

[0025] For example, the axial groove is made in the thickness of the closure member.

[0026] The axial groove may extend axially over at least a portion of the closure member.

[0027] Alternatively, the axial groove may extend axially the full length of the closure member, from the free end of the closure member to gripping member 64a.

[0028] The collecting portion may comprise a plurality of axial grooves.

[0029] Said plurality of axial grooves can be regularly spaced apart on the entire circumference of the closure member.

[0030] Alternatively, said plurality of axial grooves may be irregularly spaced apart on the entire circumference of the closure member.

[0031] Axial grooves can have the same axial length or different axial lengths.

[0032] The axial grooves allow to collect a part of the product contained in the container. The user can then test said collected part before using the entire product.

[0033] In one embodiment, the sampling portion comprises at least one annular groove.

[0034] For example, the annular groove is made in the thickness of the closure member.

[0035] The annular groove may extend over at least a portion of the circumference of the closure member.

[0036] Alternatively, the annular groove may extend over the entire circumference of the closure member.

[0037] The collecting portion may comprise a plurality of annular grooves.

[0038] Said plurality of annular grooves can be regularly spaced axially away from the closure member extending from a free end of said closure member to the gripping member 84a.

[0039] Alternatively, said plurality of annular grooves may be unevenly offset from the entire axial length of the closure member.

[0040] The annular grooves can have the same axial width or a different axial width.

[0041] In an embodiment not shown in the Figures, it is possible to provide a groove having a plurality of annular portions separated by a solid portion.

[0042] The annular groove allows to collect a part of the product contained in the container. The user can then test said extracted part before using the entire product.

[0043] The closure may comprise a handling element having a gripper and a body extending from the gripper.

[0044] The body is, for example, tubular and, for example, is provided with an annular sealing flange at an end opposite the handle.

[0045] In one embodiment, the device comprises an application member mounted to the at least one container having at least two rows of elastically deformable application teeth disposed on either side of the dispensing closure and extending outwardly from the said at least one container, said application teeth each being inclined to the longitudinal geometric axis of the first dispensing orifice, and at least a plurality of teeth of said rows of teeth are deformed into a stressed position by contact with the dispensing closure and configured to elastically return to a rest position when the dispensing closure is removed, in said rest position the teeth are more inclined towards the longitudinal axis of the first dispensing orifice than in the stressed position.

[0046] At least one plurality of teeth of the two rows of teeth is deformed into a stressed position by contact with the dispensing closure and is configured to elastically return to a second position that corresponds to the resting position of the teeth when dispensing closure is removed.

[0047] In the rest position, the teeth are more inclined towards the longitudinal axis of the first dispensing orifice than in the stressed position.

[0048] In other words, the teeth are, therefore, capable, from the material used and/or its dimension, of being deformed under a light request, for example, by the dispensing closure, or by the user during application in a application surface such as hair, and to return to its initial position when no stress is exerted on the teeth.

[0049] The elastically deformable inclined teeth allow a good retention and restitution of the product to be dispensed. In fact, product distribution is easily controlled by the slanted teeth.

[0050] During transport and before first use, when the dispensing closure is located between the teeth, the teeth are deformed in the stressed position where the teeth in contact with the dispensing closure form a first angle with the longitudinal axis .

[0051] In the rest position, the teeth form a second angle with the longitudinal axis. The second angle is larger than the first angle.

[0052] Advantageously, the application teeth extend transversely beyond the first dispensing hole.

[0053] The teeth can be shaped like a straight rod.

[0054] For example, the free ends of the teeth are not in contact in the rest position.

[0055] Advantageously, the application member comprises a cover having an opening for closing dispensing.

[0056] Each tooth may have a base section connected to the cover and a free end opposite the base section and each tooth is capable of flexing around the joint with its base section and cover.

[0057] For example, the dispensing member comprises four rows of teeth arranged two by two on each side of the dispensing closure.

[0058] The rows of teeth can be parallel to each other.

[0059] Advantageously, the teeth of two rows of adjacent teeth are in a staggered arrangement such that when the four rows are pushed towards the central geometric axis of the device, their free ends form only two rows of teeth. In other words, when the rows of teeth are brought towards the central axis of the device, the free end of teeth of a first row fits between the free ends of teeth of the second row and the free ends of teeth of a third row fit between the free ends of teeth of the fourth row.

[0060] The staggered arrangement of the teeth allows a zigzag distribution of the product to be dispensed.

[0061] Each tooth may have a triangular cross-section, which may continuously decrease, in at least part of its length, towards its free end.

[0062] The teeth can be made of a flexible, deformable material capable of bouncing back and forth, such as a thermoplastic, for example, a low-density polyethylene (LDPE), a high-density polyethylene (HDPE), a thermoplastic elastomer (TPE ), a thermoplastic polyurethane (TPU) or any material capable of being elastically deformed.

[0063] The covering can be made of a thermoplastic polymer such as polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), nylon or any material more rigid than the teeth.

[0064] In one embodiment, the device comprises a second container delimiting a second product cavity containing a second product and separate from the first product cavity, said containers being able to rotate relative to one another without moving axially.

[0065] Said device may further comprise a temporary closure member configured to close an open end of the upper container prior to first use, and comprising a cylindrical skirt surrounding said open end and a plug connected to said cylindrical skirt, being said cylindrical skirt provided, on its internal cylindrical surface, with internal threads that cooperate with external threads provided in the upper container and on its external cylindrical surface, with first anti-rotation means that cooperate with second anti-rotation means provided in the lower container to prevent rotation between the closure member and the lower container, the closure member being devoid of any axial retaining members with both containers, so that when the upper container is rotated in a first direction of rotation, the closure member translates downwardly until it drops into the first product cavity.

[0066] The present invention will be better understood from the study of the detailed description of a modality considered by means of a non-limiting example and illustrated by the attached drawings in which: - Figure 1 is a front view of a device according to a first embodiment of the present invention; Figure 2 is a cross-sectional view along line II-II of the device in Figure 1; Figure 3 is a cross-sectional view along line III-III of the device in Figure 2; Figure 4 is a front view of the device of Figure 1, after removing an end closure; - Figure 5 is a top view of the device in Figure 4; - Figures 6 to 8 show details of the Figure 1 device; Figure 9 is a cross-sectional view of a lower container of the device of Figure 1, showing anti-rotation means; Figure 10 is a perspective view of a closure member of the Figure 1 device; Figure 11 shows the device of Figure 1 in an open position of an upper container after rotation of the upper container in a first rotation direction; Figure 12 is a cross-sectional view of a device according to another embodiment of the present invention; and - Figures 13 to 15 show different modalities of the end closure of the Figure 12 device.

[0067] Figures 1 to 11 show an example of a device for packaging two products separately and dispensing a mixture M of such two products in first use, denoted by the general numerical reference 10.

[0068] The device 10 can be used to package two cosmetic products A and B, for example, two liquid or semi-liquid cosmetic products, or a liquid product and a powder. For example, the products can be hair care products such as hair care products, for example hair dye, hair cream or any other used hair care product. However, it may be possible to provide the packaging and dispensing of other types of products. Device 10 is suitable for one application products. By way of example, the first product A is an oxidative dye and the second product is an oxidizing agent B which, when mixed together to make a mixture M, form a hair dye.

[0069] The device 10 can also be used to package other types of cosmetic products such as skin care products, or other types of products such as food products, such as flavored liquids, or any products that can be kept separate during transport and storage , such as adhesive products, polymeric coatings, etc.

[0070] However, device 10 can also be used to pack and dispense only a single product.

[0071] The device 10 extends along a longitudinal geometric axis X-X' which is assumed to be vertical in the Figures. The device 10 comprises a lower vessel 12 and an upper vessel 14 which are capable of rotating relative to each other around said longitudinal axis X-X'.

[0072] When used to package and dispense only one product, the device may comprise only the upper container 14, not the lower container 12, or both containers, however, the upper container acts as a dispensing member.

[0073] The lower container 12 is shaped like a bottle that has an elongated body along the longitudinal geometric axis provided with a closed lower end 16 forming a bottom end and an upper end 18, forming a neck provided with an opening 20, opposite the lower end 16, allowing access to the internal cavity 22 containing the first product A.

[0074] In the illustrated embodiment, the neck 18 has an outer diameter smaller than the outer diameter of the lower container body 12 and comprises, on its outer surface, two outer annular shoulders 18a delimiting an annular groove 18b. The lower container body 12 can be made, for example, of rigid plastic material.

[0075] The upper container 14 is in the form of a cap and comprises a chimney or central dispensing duct 24 containing the second product B which has an upper portion shaped with a dispensing closure 26 and a lower end provided with an opening 28 , opposite the dispensing closure 26, and allowing access to an internal cavity 24a of the duct 24 containing the second product B.

[0076] The dispensing closure 26 is designed to be broken for first use in order to open a dispensing orifice 24b in flow communication with the internal cavity 24a.

[0077] In the embodiments shown in Figures 1 to 10, the dispensing closure 26 is fragile. Alternatively, the dispensing closure 26 can be unscrewed or detached or detached from the duct 24.

[0078] As illustrated, the end of the duct 24 is provided with notches 26a in order to easily separate the dispensing closure 26 from the duct 24. A plurality of notches 26a may be located circumferentially around the duct 24 and spaced apart from one another. Alternatively, a single notch 26a can be provided around the duct 24.

[0079] The dispensing closure 26 may be provided with a plug (not shown) opposite the notches 26a designed to be inserted into the dispensing hole 24b after the dispensing closure 26 is removed from the duct 24. The dispensing closure 26, therefore , is repositionable and can close the dispensing hole after use.

[0080] The dispensing duct 24 is surrounded by a mounting skirt 30 provided on its radially inner surface with an annular microsphere 30a which cooperates with the annular groove 18b of the lower container 12 by gripping with snap fit, so that the container upper 14 is retained axially with respect to lower container 12 while allowing a rotational movement relative to one another.

[0081] The upper container 14 has an annular sealing rim 32 extending substantially along the longitudinal axis XX' downwards in an annular channel 14a formed between the dispensing flue 24 and the mounting skirt 30. seal 32 is annular and bears closely against the radially inner surface of a portion 18c of neck 18, which surface is annular, thus providing a seal between lower container 12 and upper container 14.

[0082] Advantageously, the annular sealing rim 32 of the upper container 14 is configured to be elastically deformed in the radial direction against the sealing portion 18c of the neck 18 by inserting the dispensing duct 24 of the upper container 14 into the neck 18 of the container lower 12.

[0083] In particular, the sealing portion 18c of the neck 18 comprises an slope extending inwardly in the radial direction of an upper portion 18d of the neck, this slope assisting the elastic deformation of the annular sealing rim 32 of the upper container 14 when it is mounted in the lower container 12.

[0084] Advantageously, the upper portion 18d of the neck 18 of the lower container 12 has an inner diameter that is greater than the outer diameter of the annular sealing rim 32 of the upper container 14. Therefore, the risk that the open end of the neck 18 of the lower container 12 and the annular sealing rim 32 are damaged by mutual contact when the upper container 14 is mounted on the lower container 12 is reduced.

[0085] The sealing portion 18c is located axially in the opposite direction to the open end of the neck 18 and therefore is not subjected to degradation when the lower container is loaded by its neck and/or when the upper container 14 is mounted on the container lower 12.

[0086] The sealing portion 18c has a c-shaped cross-sectional shape, which allows said sealing portion 18c to be elastically deformed by inserting the dispensing chimney 24 of the upper container 14 into the neck 18 of the lower container 12. Such a shape In particular, the radial interference between the sealing portion 18c and the sealing lip 32 increases. The airtightness of the device 10 is therefore increased.

The upper portion 18d of the neck 18 is configured to guide the upper container 14 until the mounting skirt 30 of the dispensing chimney 24 cooperates by snap-fit grip with the lower container 12.

[0088] As illustrated, the upper container 14 further comprises an application member 40 mounted to the dispensing chimney 24 and comprising a cover 42 mounted to the upper end of the dispensing chimney 24 and a plurality of application tines 44 extending to out from said cover 42.

[0089] Cover 42 comprises an opening 42a for dispensing closure 26.

[0090] As a non-limiting example, the application member 40 comprises four rows 44a, 44b, 44c, 44d of application teeth 44, each inclined to the flow path of the product to be dispensed.

[0091] Alternatively, the application member 40 may comprise only two rows of application teeth 44 or more than four.

[0092] All teeth 44 are inclined to the central longitudinal axis X-X' of device 10.

[0093] Each tine 44 has a base section connected to cover 42 and a free end opposite the base section.

[0094] Each tooth 44 is elastically deformable and capable of flexing around the joint with its base section and cover 42.

[0095] In other words, the teeth are, therefore, capable, from the material used and/or its dimension, of being deformed under a light request, for example, by the closing of dispensing 26, or by the user during application in an application surface such as the hair and/or the scalp, and to return to its initial position when no stress is exerted on the teeth.

[0096] As illustrated in Figures 1 to 3, during transport and before first use, the dispensing orifice 24b of the top container 14 is closed by the dispensing closure 26, which is located between the dispensing teeth 44. The plurality of teeth 44 are therefore arranged two at a time on either side of the dispensing closure 26. The rows 44a, 44b, 44c, 44d of the plurality of teeth 44 are parallel to each other.

[0097] As illustrated in Figure 5, the teeth 44 of two rows of adjacent teeth 44a, 44b; 44c, 44d are in a staggered arrangement such that when the four rows are pushed to the geometric axis XX' of the dispensing orifice 24b, their free ends form just two rows of teeth 44. In other words, when the rows of teeth are brought to the axis XX' of the dispensing hole 24b, the tooth free ends 44 of a first row 44a fit between the tooth free ends 44 of the second row 44b and the tooth free ends 44 of a third row 44c fit between the free ends of teeth 44 of the fourth row 44d.

[0098] During transport and before first use, when the dispensing closure 26 is located between the teeth 44, the teeth 44 of the second and fourth rows 44b, 44d of teeth are mechanically stressed in a first position in which the teeth 44 in contact with the dispensing closure 26 form a first angle α1 with the longitudinal axis.

[0099] When the dispensing closure 26 is removed, the teeth 42 of the second and fourth rows 44b, 44d of teeth that were in contact with the dispensing closure 26 are automatically flexed into a second position corresponding to the rest position of the teeth. In this rest position, the teeth of the second and fourth rows 44b, 44d of teeth form a second angle α2 with the longitudinal axis. The second angle is larger than the first angle.

[0100] In this rest position, the free end of the teeth of the second and fourth rows 44b, 44d of teeth are in the flow path of the product to be dispensed.

[0101] The elastically deformable inclined teeth 44 allow a good retention and restitution of the product to be dispensed. In fact, product distribution is easily controlled by the slanted teeth 44.

[0102] Furthermore, the staggered arrangement of the teeth 44 allows a zigzag distribution of the product to be dispensed.

[0103] Each tooth 44 has a triangular cross-section. The cross-section of each tooth may continuously decrease, over at least a part of its length, towards its free end.

[0104] As illustrated, the application tines extend transversely beyond the first dispensing hole, and the tines are shaped like a straight rod.

[0105] The free ends of the teeth are not in contact in the rest position.

[0106] Teeth 44 are made of a flexible, deformable material capable of bouncing back and forth, such as a thermoplastic, eg a low-density polyethylene (LDPE), a high-density polyethylene (HDPE), a thermoplastic elastomer (TPE) ), a thermoplastic polyurethane (TPU) or any material capable of being elastically deformed.

[0107] Cover 42 and/or top container 14 can be made of a thermoplastic polymer, such as polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), nylon or any material more rigid than teeth 44.

[0108] As illustrated in Figures 2 and 3, during transport and before first use, a temporary closure member 50. In the illustrated example, the closure member 50 is a cap that is capable of being screwed in, in a sealed manner , in an external thread 28a provided on the outer surface of the lower end 28 of the dispensing chimney 24, between the dispensing chimney 24 and the inner surface of the neck 18.

[0109] The closure member 50 comprises a cylindrical skirt 52 and a plug 54 connected to said skirt 52. The cylindrical skirt 52 extends radially between the neck 18 of the lower container 12 and the lower end 28 of the dispensing chimney 24 of the container superior 14.

[0110] The cylindrical skirt 52 is provided, on its inner cylindrical surface, with internal threads 42a that cooperate with the external thread 28a of the dispensing chimney 24.

[0111] The cylindrical skirt 52 is additionally provided, on its outer cylindrical surface, with outer longitudinal ribs 52b regularly spaced apart on the entire circumference of the cylindrical skirt 52. Said outer longitudinal ribs 52b cooperate with inner longitudinal ribs 18e provided on the inner circumferential surface of the neck 18, so that the closure member 50 is prevented from rotating relative to the lower container 12.

[0112] As illustrated and in a non-limiting example, the outer longitudinal ribs 52b extend axially beyond the upper surface of the cylindrical skirt

52.

[0113] In one example shown, the outside diameter of the plug 54 is greater than the outside diameter of the open end 28 of the dispensing chimney 24.

[0114] The cylindrical skirt 52 and the lower container 12 can be provided with anti-rotation means that have a different shape from the longitudinal ribs. Generally, the cylindrical skirt 52 and the lower container 12 are provided with anti-rotation means to prevent the closure member 50 from rotating relative to the lower container.

12.

[0115] The upper surface of the plug 54 comprises a first annular sealing bead 54a extending axially to the upper container 14 and having an outer diameter substantially equal to the inner diameter of the lower open end 28 of the dispensing chimney 24 to be inserted in said dispensing chimney 24 and to close the same in a sealed manner.

[0116] The upper surface of the plug 54 comprises a second annular sealing bead 54b which extends axially in an annular groove 28b provided at the end of the lower open end 28.

[0117] As illustrated, the second sealing lip 54b has an axial length less than the axial length of the first sealing lip 54a.

[0118] Adding a second sealing lip increases the airtightness of the top container 14.

[0119] The plug 54 is connected by a bridge of hinge-forming material 54c and by loops or connections of breakable material 54d to the cylindrical skirt

52. In the embodiment shown in the Figures, there are seven breakable material links 54d regularly spaced apart on the circumference of the plug 54. It may be possible to provide a number of breakable links 54d other than seven. For example, plug 54 is connected to cylindrical skirt 52 by a bridge of hinge-forming material 54c and by at least one frangible link 54d.

[0120] As shown, the plug 54 comprises a plurality of axially projecting blocks or bars 54e provided on the lower surface of the plug 54, opposite the upper surface of the plug 54 which has an annular sealing lip 54a, 54b. The axially projecting blocks 54e are circumferentially disposed on the lower surface of the plug 54 and are regularly spaced apart from one another.

[0121] As illustrated in Figure 9, there are four 44e blocks. However, the number of blocks 54e is not limited to four and can be, for example, equal to one, two or three, or greater than four.

[0122] The blocks 54e are arranged at a diameter of the plug 54 substantially equal to the diameter of the dispensing chimney 24, so that when the closure member 50 is poured into the lower container 12, the blocks 54e avoid clogging the open lower end 28 of the dispensing chimney 24.

[0123] It is also possible to provide a closure member without axially projecting blocks 54e and/or without breakable links 54d and bridge 54c.

[0124] In a non-limited example, the first direction of rotation can be a clockwise or counterclockwise direction.

[0125] Device 10 is mounted as follows.

[0126] The upper container 14 is filled with the second product B and the closure member 50 is screwed onto the dispensing chimney 24 until the plug 54 axially rests against the open end 28 of said dispensing chimney 24.

[0127] The upper container 14 is fitted in a simple translational movement along the longitudinal geometric axis XX' in the lower container 12 that was previously filled with the first product A, until the mounting skirt 30 of the upper container 14 engages by pressing the neck 18 of the lower container

12.

[0128] In order to place the internal volume 24a of the upper container 14 in flow communication with the internal volume 22 of the lower container 12 in the first use of the device 10, the user rotates the upper container 14 relative to the lower container 12 in a first direction of rotation F1, as shown in Figure 10, causing the closure member 50 to translate downwardly along the longitudinal axis XX' compared to the lower container 12, until it falls into the inner volume 22 of said lower container 12.

[0129] As illustrated in Figure 10, and in a non-limited example, the first rotation direction F1 is a counterclockwise direction. The first direction of rotation can also be a clockwise direction.

[0130] In this mode, once the closure member 50 is in the inner volume 22 of the lower container 12, said closure member acts as a stirring member for the mixture M comprising the first and second products A, B by twisting and shaking movements of the device 10.

[0131] The user then breaks the frangible dispensing closure 26 to use the device 10 and dispense the resulting mixture M contained in the lower container 12 through the dispensing stack 24 and the dispensing port 24b.

[0132] Bottom container 12 can be processed with injection blow molding process. The lower container 12 is made, for example, of polymeric material such as thermoplastic material. The lower container 12, for example, is injection molded into a preform core consisting of the neck container with the thick tube of polymeric material attached. The preform core has longitudinal outer ribs which will form the anti-rotation longitudinal ribs 18e provided on the inner circumferential surface of the neck 18 when compressed air is filled into the preform to inflate the thick tube in the bottle shape of the lower container.

[0133] The longitudinal anti-rotation ribs 18e are therefore filled directly during the injection blow molding process of the lower container 12.

[0134] When the user rotates the upper container in a second rotation direction F2, as shown in Figure 12, the closure member 50 translates upward until the breakable links 54c are forcibly broken causing the plug 54 to pivot to the around the bridge of hinge-forming material 54b and the second product B flows into the inner cavity 22 of the lower container 12.

[0135] As illustrated in Figure 12, and in a non-limited example, the second rotation direction F2 is a clockwise direction. The second direction of rotation F2 could also be a counterclockwise direction as in Figure 10.

[0136] The user may additionally rotate the upper container 14 in a rotation direction opposite to the second rotation direction F2 in order to translate the closure member 50 downward until it falls into the inner cavity 22 of the lower container 12. (not shown in the Figures)

[0137] In the modality, the user can open the dispensing chimney 24 by rotating the upper container 14 in both directions of rotation.
