Description

The invention generally relates to the field of testing devices used with a packaging and dispensing device for testing a liquid agent or a semi-liquid agent, for example a cosmetic product such as a hair product, and in particular a hair care product such as a serum for hair dye, hair oil, hair cream, or product used for washing, such as body wash, or skin care product, such as body or face cream, cleanser, or any product used for hair or skin care, or a mixture before applying the entire agent, as well as with a container having a plurality of comb teeth designed to apply the agent to the surface.

The expression "cosmetic" means a product as defined in Article 2 of Regulation No. 1223/2009 of the European Parliament and of the Council of 30 November 2009.

As a general rule, considering testing an agent or mixture prior to applying the entire agent, for example to detect a potential allergy of the user to that agent or mixture, it is known to use a cotton swab or to add a separate sampling element.

Reference can be made to US 2007/0180895-A1, which describes a packaging system having a single container and a testing device shaped like a cotton swab.

However, these solutions for selecting a portion of the agent to be tested are not effective.

One advantageous application of the present invention is the use of a container for packaging cosmetics, such as cosmetics for coloring human keratin fibers. Other advantageous applications of the invention would be the use of a storage container for care products, adhesives, polymeric coatings, flavored liquids, etc.

One object of the present invention is to provide a device for packaging at least one product with a simple design, easy to manufacture and having an integrated selection element.

The aim of the present invention is to provide a device for packaging at least one agent and delivering at least said agent to a surface, such as hair. Said device comprises at least one container limiting the agent cavity, containing said at least one agent and a closure capable of closing the first opening for supplying the container in fluid communication with the agent cavity.

Said closure is equipped with a collecting part configured to collect the agent contained in the agent cavity.

Thus, there is no need to add a separate collection element or use a cotton swab to test the product before the first use. The agent can be assembled and tested directly with the closure of the device.

Preferably, the closure has a closure suitable for closing the supply opening of the container.

Said closure may be tubular or may have any other shape suitable for closing said supply opening.

For example, the closure element contains a collecting part.

The collecting part may be formed on said closure member.

For example, the collecting part is made to pass through the thickness of the closure.

In an embodiment, the closure includes a fastener designed to engage with a mating fastener provided on the inner surface of the supply opening.

The fastener may be provided with a quarter turn.

Alternatively, any other fastener, such as a screw thread, a clamp mechanism, a snap mechanism, etc., may be used to temporarily secure the delivery restriction closure in the delivery opening.

The collecting part is, for example, at least one opening provided on the closure element near its free end.

The opening may be a through hole provided through the thickness of the closure.

It is also possible to provide a plurality of holes or through holes provided on the closure member.

The opening may be rectangular, circular, triangular, or any other shape suitable for collecting a portion of the agent contained in the cavity.

The hole allows you to collect part of the product contained in the container. The user can then test said assembled part before using the entire tool.

In another embodiment, the collecting part contains at least one axial groove.

For example, the axial groove is made in the thickness of the closure.

The axial groove may extend in the axial direction on at least one part of the closure.

Alternatively, the axial groove may extend axially along the entire length of the closure from the free end of the closure to the fastener 64a.

The collecting portion may include a plurality of axial grooves.

Said plurality of axial grooves may be evenly spaced around the entire circumference of the closure.

Alternatively, said plurality of axial grooves may be unevenly spaced around the entire circumference of the closure.

The axial grooves may have the same axial length or different axial lengths.

Axial grooves make it possible to collect part of the product contained in the container. The user can then test said assembled part before using the entire tool.

In an embodiment, the bleed portion comprises at least one annular groove.

For example, the annular groove is made in the thickness of the closure.

The annular groove may pass through the kerosene at least one part of the circumference of the closure.

Alternatively, the annular groove may extend around the entire circumference of the closure.

The collecting portion may include a plurality of annular grooves.

Said plurality of annular grooves may be evenly spaced axially from the closure extending from the free end of said closure to the fastener 84a.

Alternatively, said plurality of annular grooves may be unevenly spaced along the entire axial length of the closure.

The annular grooves may have the same axial width or different axial widths.

In an embodiment not shown in the figures, a groove can be provided having a plurality of annular portions separated by a hard portion.

The annular groove allows you to collect part of the agent contained in the container. The user can then test the specified extracted portion before using the entire tool.

The closure may comprise a handling element having a grip and a body extending from the grip.

The main body is, for example, tubular and, for example, is equipped with a sealing annular flange at the end opposite to the grip.

In an embodiment, the device comprises an application element mounted on at least one container having at least two rows of resiliently deformable application teeth located on both sides of the closure to limit the flow and extending outward from said at least one container, wherein each of said application teeth is inclined to the longitudinal axis of the first supply opening and at least a plurality of teeth from said rows of teeth are deformed in a stressed position due to contact with the supply limiting closure and are configured to elastically return to their original position when the closure is removed. feed limiting means, wherein in said initial position the teeth are inclined to the longitudinal axis of the first feed opening to a greater extent than in the stressed position.

At least a plurality of teeth of the two rows of teeth deform in a stressed position due to contact with the flow restriction closure and are configured to resiliently return to a second position that corresponds to the initial position of the teeth when the flow restriction closure is removed.

In the initial position, the teeth are inclined to the longitudinal axis of the first feed hole to a greater extent than in the stressed position.

In other words, the prongs are thus capable of deforming, due to the material used and/or their size, upon slight impact, for example by a feed-limiting closure or by the user during application to an application surface such as hair, and return to their original position. when the teeth are not affected.

The resiliently deformable sloping teeth ensure a secure holding and return of the agent to be dispensed. Indeed, the distribution of the agent is easily controlled by the inclined teeth.

During transport and prior to first use, when the flow restriction closure is positioned between the teeth, the teeth are deformed in a stressed position in which the teeth coming into contact with the flow restriction closure form a first angle with the longitudinal axis.

In the initial position, the teeth form a second angle with the longitudinal axis. The second angle is greater than the first angle.

Advantageously, the application teeth extend transversely past the first supply opening.

The teeth may be in the form of a straight rod.

For example, in the initial position, the free ends of the teeth are not in contact.

Preferably, the application member comprises a lid having a closure opening to restrict delivery.

Each prong may have a base section connected to the lid and a free end opposite the base section, and each prong being able to flex around the connection to its base section and the lid.

For example, the applicator contains four rows of prongs arranged two by two on each side of the feed restricting closure.

Rows of teeth may be parallel to each other.

Advantageously, the teeth of two adjacent rows of teeth are staggered so that when the four rows are shifted towards the central axis of the device, their free ends form only two rows of teeth. In other words, when the rows of teeth are close to the central axis of the device, the free ends of the teeth of the first row are placed between the free ends of the teeth of the second row, and the free ends of the teeth of the third row are placed between the free ends of the teeth of the fourth row.

The staggered arrangement of the teeth ensures a zigzag distribution of the product to be dispensed.

Each barb may have a triangular cross section which may decrease continuously over at least a portion of its length towards its free end.

The teeth may be made from a flexible, deformable and rebound material such as a thermoplastic material such as low density polyethylene (LDPE), high density polyethylene (HDPE), thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), or any material capable of elastic deformation.

The lid can be made from a thermoplastic polymer such as polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), nylon, or any material stiffer than the prongs.

In an embodiment, the device comprises a second container defining a second agent cavity containing the second agent and separated from the first agent cavity, said containers being able to rotate relative to each other without moving in the axial direction.

Said device may further comprise a temporary closure element configured to close the open end of the upper container before first use and comprising a cylindrical band surrounding said open end and a plug connected to said cylindrical band, said cylindrical band on its inner cylindrical surface having an internal thread , interacting with the external thread provided on the upper container, and on its outer cylindrical surface, a first rotation prevention means is provided, interacting with a second rotation prevention means provided on the lower container, to prevent rotation between the closure element and the lower container, and the closure element does not have any holding elements in the axial direction on both containers, so that when the upper container rotates in the first direction of rotation, the closure element moves downward until it falls t in the first cavity for the agent.

The present invention will be better understood by examining the detailed description of an embodiment, taken as a non-limiting example and illustrated by the accompanying drawings, in which:

in fig. 13-15 show various embodiments of the end closure of the device shown in FIG. 12.

In FIG. 1-11 shows an example of an apparatus for separately packaging two agents and supplying a mixture M of the two upon first use, designated by the general reference numeral 10.

The device 10 can be used to package two cosmetics A and B, for example two liquid or semi-liquid cosmetics or a liquid and a powder. For example, the agents may represent a failure of hair products, such as hair care products, for example, hair dye, hair cream, or any product used for hair. However, it is possible to ensure the packaging and supply of other types of funds. Device 10 is suitable for single application products. For example, the first agent A is an oxidant dye and the second agent is an oxidant B, which, when mixed to form a mixture M, form a hair dye.

The device 10 can also be used to package other types of cosmetics, such as skin care products, or other types of products, such as food products such as flavored liquids, or any products that can be stored separately during transport and storage, such as as adhesives, polymer coatings, etc.

However, the device 10 can also be used to pack and dispense only one product.

The device 10 extends along the longitudinal axis X-X', which is assumed to be vertical in the figures. The device 10 includes a lower container 12 and an upper container 14, which can be rotated relative to each other about the specified longitudinal axis X-X'.

When used for packaging and supplying only one means, the device may contain only the upper container 14 without the lower container 12, or both containers, but the upper container functions as a supply element.

The lower container 12 is in the form of a bottle, having an elongated body along the longitudinal axis, equipped with a closed lower end 16 forming a bottom and an upper end 18 forming a neck, equipped with an opening 20, and located opposite the lower end 16, providing access to the internal cavity 22 containing first remedy A.

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

The upper container 14 is cap-shaped and includes a central supply tube or conduit 24 containing a second means B, the upper part of which is in the form of a supply restriction closure 26 and the lower end is provided with an opening 28 opposite the supply restriction closure 26 and allowing access to the inner cavity 24a of the channel 24 containing the second means B.

The feed restriction closure 26 is designed to be broken upon first use to expose the feed port 24b in fluid communication with the interior cavity 24a.

In the embodiments shown in FIG. 1 to 10, the feed restricting closure 26 is brittle. Alternatively, the flow restriction closure 26 may be unscrewed, torn off, or removed from the channel 24.

As shown, the end of the channel 24 is provided with notches 26a for the purpose of easily separating the restrictive closure 26 from the channel 24. A plurality of notches 26a may be arranged circumferentially around the channel 24 and spaced apart. Alternatively, a single recess 26a may be provided around the channel 24.

The flow restriction closure 26 may be provided with a plug (not shown) opposite the notches 26a to be inserted into the supply hole 24b after the supply restriction closure 26 is broken off from the passage 24. Thus, the supply restriction closure 26 can be reinstalled. and close the feed opening after use.

The supply channel 24 is surrounded by an assembly belt 30 provided on its radially inner surface with an annular collar 30a cooperating with the annular groove 18b of the lower container 12 by means of a snap connection so that the upper container 14 is held axially relative to the lower container 12 while allowing rotation movement relative to one another.

The upper container 14 has an annular sealing lip 32 extending substantially along the longitudinal axis X-X' downward into an annular passage 14a formed between the supply tube 24 and the assembly band 30. The sealing lip 32 is annular and seals against the radially inner surface of the annular surface portion 18c of the neck 18, thereby providing a seal between the lower container 12 and the upper container 14.

Advantageously, the annular sealing lip 32 of the upper container 14 is configured to be elastically deformable in the radial direction relative to the sealing portion 18c of the neck 18 when the channel 24 for supplying the upper container 14 is inserted into the neck 18 of the lower container 12.

In particular, the sealing portion 18c of the neck 18 has an inclination extending radially inwardly from the upper portion 18d of the neck, which inclination contributes to the elastic deformation of the annular sealing lip 32 of the upper container 14 when it is assembled on the lower container 12.

Advantageously, the upper part 18d of the neck 18 of the lower container 12 has an inner diameter that is larger than the outer diameter of the annular sealing lip 32 of the upper container 14. Therefore, there is a risk that the open end of the neck 18 of the lower container 12 and the annular sealing lip 32 will be damaged due to mutual contact when the upper container 14 is collected on the lower container 12 is reduced.

The seal portion 18c is located axially away from the open end of the neck 18 and thus is not destroyed when the lower container is carried past its neck and/or when the upper container 14 is assembled on the lower container 12.

The sealing portion 18c is c-shaped in cross section, which allows said sealing portion 18c to be elastically deformed when the tube 24 for supplying the upper container 14 is inserted into the neck 18 of the lower container 12. This particular shape increases the radial engagement between the sealing portion 18c and the sealing lip 32. Thus, the tightness of the device 10 is increased.

The top 18d of the neck 18 is configured to guide the upper container 14 until the belt 30 for assembling the supply tube 24 engages through a snap connection with the lower container 12.

As shown, the top container 14 further comprises an application member 40 mounted on the supply tube 24 and comprising a lid 42 mounted on the upper end of the supply tube 24 and a plurality of application teeth 44 protruding outward from said lid 42.

The lid 42 includes an opening 42a for a feed restricting closure 26.

As a non-limiting example, the application element 40 comprises four rows 44a, 44b, 44c, 44d of application teeth 44, each of which is inclined towards the flow path of the agent to be applied.

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

All teeth 44 are inclined towards the central longitudinal axis X-X' of the device 10.

Each barb 44 has a base section connected to cap 42 and a free end opposite the base section.

Each barb 44 is resiliently deformable and capable of bending around the connection to its base section and cap 42.

In other words, the prongs are thus capable of deforming, due to the material used and/or their size, with little impact, for example, by the feed-limiting closure 26 or by the user during application to an application surface such as hair and/or scalp, and return to their original position when the teeth are not affected.

As shown in FIG. 1-3, during transport and before first use, the feed opening 24b of the upper container 14 is closed with a feed restriction closure 26 which is located between the application teeth 44. Thus, rows of a plurality of teeth 44 are arranged two on each of the two sides of the feed restricting closure 26. The rows 44a, 44b, 44c, 44d of the plurality of teeth 44 are parallel to each other.

As shown in FIG. 5, teeth 44 of two adjacent rows of teeth 44a, 44b; 44c, 44d are staggered so that when the four rows are shifted toward the axis X-X' of the feed hole 24b, their free ends form only two rows of teeth 44. In other words, when the rows of teeth are brought closer to the axis X-X' of the feed hole 24b , the free ends of the teeth 44 of the first row 44a are placed between the free ends of the teeth 44 of the second row 44b and the free ends of the teeth 44 of the third row 44c are placed between the free ends of the teeth 44 of the fourth row 44d.

During transport and prior to first use, when the feed restricting closure 26 is positioned between the teeth 44, the teeth 44 of the second and fourth rows 44b, 44d of teeth are stressed in the first position, in which the teeth 44 coming into contact with the closure 26 for feed restrictions form a first angle α1 with the longitudinal axis.

When the feed restriction closure 26 is removed, the teeth 42 of the second and fourth rows 44b, 44d of teeth that were in contact with the feed restriction closure 26 are automatically bent to a second position which corresponds to the initial position of the teeth. In this initial position, the teeth of the second and fourth rows 44b, 44d of the teeth form a second angle α2 with the longitudinal axis. The second angle is greater than the first angle.

In this initial position, the free ends of the teeth of the second and fourth rows 44b, 44d of the teeth are in the path of the flow of the agent to be supplied.

The resiliently deformable inclined teeth 44 securely hold and return the agent to be dispensed. Indeed, the distribution of the agent is easily controlled by the inclined teeth 44.

In addition, the staggered arrangement of the teeth 44 ensures a zigzag distribution of the agent to be dispensed.

Each tooth 44 has a triangular cross section. The cross section of each tooth may decrease continuously over at least a portion of its length towards its free end.

As shown, the application prongs extend transversely past the first supply port and the prongs are in the form of a straight rod.

In the initial position, the free ends of the teeth are not in contact.

The teeth 44 are made of a flexible, deformable and rebound material such as a thermoplastic material such as low density polyethylene (LDPE), high density polyethylene (HDPE), thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), or any material capable of elastic deformation.

Lid 42 and/or top container 14 may be made of a thermoplastic polymer such as polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), nylon, or any material stiffer than the teeth 44.

As shown in FIG. 2 and 3, during transport and before first use, a temporary closure 50. In the illustrated example, the closure 50 is a cap that can be screwed with a seal onto an external thread 28a provided on the outer surface of the lower end 28 of the tube 24 for supply between the tube 24 for feeding and the inner surface of the neck 18.

Closing element 50 comprises a cylindrical band 52 and a plug 54 connected to said band 52. Cylindrical band 52 extends in the radial direction between the neck 18 of the lower container 12 and the lower end 28 of the tube 24 for supplying the upper container 14.

The cylindrical collar 52 has on its inner cylindrical surface an internal thread 42a cooperating with an external thread 28a of the feed tube 24.

On the cylindrical band 52, on its outer cylindrical surface, there are additionally provided outer longitudinal ribs 52b evenly spaced around the entire circumference of the cylindrical band 52. Said outer longitudinal ribs 52b interact with the inner longitudinal ribs 18e provided on the inner peripheral surface of the neck 18 in such a way that the closing element 50 cannot rotate relative to the lower container 12.

As shown and in a non-limiting example, the outer longitudinal ribs 52b extend axially beyond the upper surface of the cylindrical band 52.

In the example shown, the outer diameter of the plug 54 is larger than the outer diameter of the open end 28 of the supply tube 24.

The cylindrical band 52 and the bottom container 12 may be provided with a rotation prevention means, the shape of which differs from that of the longitudinal ribs. Typically, the cylindrical band 52 and the bottom container 12 are provided with an anti-rotation means to prevent rotation of the closure 50 relative to the bottom container 12.

The top surface of the plug 54 comprises a first annular sealing lip 54a extending axially to the top container 14 and having an outer diameter substantially equal to the inner diameter of the lower open end 28 of the supply tube 24 for the purpose of being inserted into said supply tube 24 and sealed. closing.

The top surface of the plug 54 includes a second annular sealing lip 54b extending axially into an annular groove 28b provided at the end of the lower open end 28.

As shown, the second sealing lip 54b has an axial length less than the axial length of the first sealing lip 54a.

The addition of a second sealing lip increases the tightness of the upper container 14.

The plug 54 is connected by a web of material 54c forming a hinge and joints or links of tear material 54d with a cylindrical band 52. In the embodiment shown in the figures, there are seven joints of tear material 54d evenly spaced around the circumference of the plug 54. A number can be provided. discontinuous connections 54d other than seven. For example, plug 54 is connected to cylindrical band 52 by a web of hinge material 54c and at least one break joint 54d.

As shown, the plug 54 includes a plurality of axially protruding rods or blocks 54e provided on the bottom surface of the plug 54, opposite the top surface of the plug 54 having annular sealing lips 54a, 54b. The axially protruding blocks 54e are arranged circumferentially on the bottom surface of the plug 54 and are evenly spaced apart from each other.

As shown in FIG. 9, four blocks 44e are present. However, the number of blocks 54e is not limited to four, and may be, for example, one, two or three, or more than four.

The blocks 54e are positioned on a plug 54 diameter substantially equal to the diameter of the supply tube 24 so that when the closure 50 falls into the lower container 12, the blocks 54e do not prevent the lower end 28 of the supply tube 24 from opening.

It is also possible to provide a closing element without axially protruding blocks 54e and/or without discontinuous connections 54d and web 54c.

In a non-limiting example, the first direction of rotation may be a clockwise or counterclockwise direction.

The device 10 is assembled as follows.

The upper container 14 is filled with the second means B and the closure 50 is screwed onto the supply tube 24 until the stopper 54 fits axially tightly against the open end 28 of said supply tube 24.

The upper container 14 is mounted with a simple translational movement along the longitudinal axis X-X' on the lower container 12, which has been previously filled with the first means A, until the belt 30 for assembling the upper container 14 snaps into place on the neck 18 of the lower container 12.

In order to communicate the internal volume 24a of the upper container 14 with the internal volume 22 of the lower container 12, when the device 10 is first used, the user rotates the upper container 14 relative to the lower container 12 in the first direction F1 of rotation, as shown in FIG. 10 causing the closure member 50 to move downward along the longitudinal axis X-X' relative to the lower container 12 until it falls into the interior volume 22 of said lower container 12.

As shown in FIG. 10 and in a non-limiting example, the first direction of rotation F1 is a counterclockwise direction. The first direction of rotation may also be a clockwise direction.

In this embodiment, when the closing element 50 is in the inner volume 22 of the lower container 12, said closing element functions as a mixing element for the mixture M containing the first and second means A, B by rotating and shaking the device 10.

The user then breaks the frangible supply restriction closure 26 to use the device 10 and supply the obtained mixture M contained in the lower container 12 through the supply tube 24 and the supply opening 24b.

The lower container 12 may be molded by injection molding. The lower container 12 is made of, for example, a polymeric material such as a thermoplastic material. The lower container 12, for example, is injection molded onto a preform core consisting of a container neck with an attached thick tube of polymeric material. The preform core has outer longitudinal ribs, which will form anti-rotation longitudinal ribs 18e provided on the inner peripheral surface of the neck 18 when compressed air is filled into the preform to inflate the thick tube into the lower capacity bottle shape.

Thus, the longitudinal anti-rotation ribs 18e are produced directly during the blow molding process of the lower container 12.

When the user rotates the upper container in the second rotation direction F2 as shown in FIG. 12, the closure member 50 is moved upward until the break connections 54c are torn apart by force, which causes the plug 54 to rotate around the web of hinge material 54b and the second means B to leak into the interior cavity 22 of the lower container 12.

As shown in FIG. 12 and in a non-limiting example, the second rotation direction F2 is a clockwise direction. The second direction of rotation F2 may also be a counterclockwise direction, as shown in FIG. ten.

The user can also rotate the upper container 14 in the direction of rotation opposite to the second direction of rotation F2 in order to move the closure element 50 down until it falls into the inner cavity 22 of the lower container 12. (not shown in the figures)

In this embodiment, the user can open the supply tube 24 by turning the top container 14 in both directions of rotation.

When using the device 10, in the event that the closure element 50 is in front of the open lower end 28 of the supply tube 24, said closure 50 will rest against said lower end 28 of its blocks 54e, thus allowing the mixture M contained in the lower container 12 to flow. , between the blocks 54e in the upper container 14 by turning said device 10 upside down.

The embodiment shown in FIG. 13 in which like elements have like reference numerals differs from the embodiment in FIG. 1-12 only the shape of the closure to restrict the flow.

As shown in FIG. 13, the feed restricting closure 60 is configured to close the feed opening 24b.

The feed restriction closure 60 includes a handling member 62 having a grip 62a and a main body 62b extending from the grip 62a. As shown, the main body 62b is tubular and is provided with a sealing annular flange 62c at the end opposite to the grip 62a.

The supply restriction closure 60 further comprises a closure 64 suitable for closing the supply opening 24b of the upper container 14. Said closure 64 is tubular. Alternatively, said closure 64 may have any other shape as long as it allows the supply opening 24b to be closed.

As shown in FIG. 13, the closure member 64 includes a fastener 64a configured to cooperate with a mating fastener provided on the inner surface of the feed opening 24b. The fastening element 64a in this case provides for a turn of a quarter of a turn. Alternatively, any other fastener, such as a screw thread, a clamping mechanism, etc., can be used to temporarily secure the feed restricting closure 60 in the feed hole 24b.

The closure element 64 further comprises a through hole 66 near its free end opposite the handling element 62.

The through hole 66 is made passing through the thickness of the closure element 64.

Alternatively, the through hole 66 may be a hole that does not extend through the thickness of the closure 64.

It is also possible to provide a plurality of through holes made through or through the thickness of the closure 64.

As shown, the through hole 66 has a rectangular shape. Alternatively, the through hole 66 may be circular, triangular, or any other shape suitable for collecting a portion of the agent contained in the cavity.

The closure 60, and especially the through hole 66, functions as a collecting element for extracting a portion of the agent contained in the upper container 14 or the mixture M contained in the lower container 12. The user can then test said extracted portion before using the entire agent.
