Description

The present invention generally relates to the field of containers for packaging and dispensing a liquid or semi-liquid product, for example a cosmetic product such as a hair product, and in particular a hair care product such as hair serum, hair dye, hair oil. hair, hair cream, or product used for washing, such as a body wash, or skin care product, such as a body or face cream, cleanser, or any product used for hair or skin care.

In particular, the present invention relates to a packaging and supply container having a plurality of comb teeth for applying an agent to a surface.

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

The term "cosmetic product" 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.

One object of the present invention is to provide a device for packaging at least one agent with a simple design, easy to manufacture and securely holding and distributing said agent over a surface.

The purpose 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 defining a cavity for the agent, containing said at least one agent and having a feed restricting closure, for example, a fragile tip, made with the possibility of separating from the container during the first use of said device to open the first supply hole , which communicates downstream with the cavity for the agent.

Said 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 feed restricting closure and extending outward from said at least one container, each said tooth for application is inclined to the longitudinal axis of the first supply opening. The application teeth thus extend towards the flow path of the agent to be dispensed.

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 rest position, the teeth are inclined more towards the longitudinal axis of the first feed hole than in the stressed position.

In other words, the prongs are thus capable of being deformed, 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.

Resiliently deformable sloping teeth ensure secure holding and return of the product 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 in 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 do not touch.

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

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

For example, the applicator contains four rows of prongs, two on each of the two sides 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.

Preferably, the end of the container is provided with recesses for the purpose of easily separating the flow restriction closure from said container.

The recesses may be arranged circumferentially around the end of the container and at a distance from each other. Alternatively, a single notch may be provided around the end of the container.

According to an embodiment, the flow restriction closure comprises a plug against the recesses for insertion into the supply opening after the flow restriction closure is broken off from the channel. Thus, the feed restricting closure can be reinstalled and close the feed opening after use.

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.

Advantageously, said device further comprises a temporary closing element configured to close the open end of the first container before first use and comprising a cylindrical band surrounding said open end and a plug connected to said cylindrical band, wherein said cylindrical band is provided on its inner cylindrical surface with an internal thread interacting with an external thread provided on the first container, and on its outer cylindrical surface, a first rotation prevention means is provided, interacting with a second rotation prevention device provided on the second container, to prevent rotation of the closing element relative to the second container. The closure element does not have any retaining elements in the axial direction on both containers, so that when the first container is rotated in the first direction of rotation, the closure element is displaced downward until it falls into the second agent cavity.

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 a device for separately packaging two agents and supplying a mixture M of the two upon first use, designated by the common 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, eg, 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 second agent A is an oxidizing dye and the first agent is an oxidizing agent 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 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 considered to be vertical in the graphics. The device 10 includes a second container 12 and a first 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 first container 14 without the second container 12, or both containers, but the first container functions as a supply element.

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

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

The first container 14 is cap-shaped and includes a central supply tube or conduit 24 containing a first 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 first agent 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 flow 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 second container 12 by a snap connection so that the first container 14 is held in the axial direction relative to the second container 12, while allowing rotation movement relative to each other.

The first upper container 14 has an annular sealing lip 32 extending substantially along the longitudinal axis X-X' down into an annular passage 14a formed between the supply tube 24 and the assembly belt 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 second container 12 and the first container 14.

Preferably, the annular sealing lip 32 of the first container 14 is made with the possibility of elastic deformation in the radial direction relative to the sealing part 18c of the neck 18 when the channel 24 for feeding the first container 14 is inserted into the neck 18 of the second container 12.

In particular, the seal 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 first container 14 when it is assembled on the second container 12.

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

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

The sealing portion 18c has a C-shape in cross section, which allows said sealing portion 18c to be elastically deformed when the tube 24 for supplying the first container 14 is inserted into the neck 18 of the second 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 first container 14 until the belt 30 for assembling the supply tube 24 interacts via a snap connection with the second container 12.

As shown, the first container 14 further comprises an applicator 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 member 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 to 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 prong 44 is resiliently deformable and capable of bending around the junction of its base section with 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 to 3, during transport and before first use, the supply opening 24b of the first container 14 is closed with a supply 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 towards the axis X-X' of the feed opening 24b, their free ends form only two rows of teeth 44. In other words, when the rows of teeth are close to the axis X-X' feed holes 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 have been 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 end of the teeth of the second and fourth rows 44b, 44d of the teeth is 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 do not touch.

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 first 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 includes a cylindrical belt 52 and a plug 54 connected to said belt 52. Cylindrical belt 52 extends in the radial direction between the neck 18 of the second container 12 and the lower end 28 of the tube 24 for supplying the first 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, external longitudinal ribs 52b are additionally provided, evenly spaced around the entire circumference of the cylindrical band 52. These outer longitudinal ribs 52b interact with the internal 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 second container 12.

As shown and in a non-limiting example, the outer longitudinal ribs 52b extend axially beyond the top 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 second 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 second container 12 are provided with anti-rotation means to prevent rotation of the closure 50 relative to the second container 12.

The top surface of the plug 54 comprises a first annular sealing lip 54a extending axially to the first container 14 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.

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

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

The plug 54 is connected by a web of material 54c forming a hinge and joints or links of frangible material 54d with a cylindrical band 52. In the embodiment shown in the figures, there are seven breakable material joints 54d spaced evenly spaced around the circumference of the plug 54. It is possible provide for a number of 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.

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 diameter of plug 54 substantially equal to the diameter of the supply tube 24 so that when the closure 50 falls into the second 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 first container 14 is filled with the first agent 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 first container 14 is installed with a simple translational movement along the longitudinal axis X-X’ on the second container 12, which was previously filled with the second means A, until the belt 30 for assembling the first container 14 is fixed by snapping onto the neck 18 of the second container 12.

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

As shown in FIG. 10 and in a non-limiting example, the first rotation direction 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 second container 12, said closing element functions as a mixing element for the mixture M containing the first and second means B, A 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 second container 12 through the supply tube 24 and the supply opening 24b.

The second container 12 may be molded by injection molding. The second container 12 is made of, for example, a polymeric material, such as a thermoplastic material. The second 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 core of the preform 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 shape of a second container bottle.

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

When the user rotates the first container in the second rotation direction F2 as shown in FIG. 12, the closure member 50 is moved upward until the rupture joints 54c are severed by force, causing the plug 54 to rotate around the web of hinge material 54b and the first means B to leak into the interior cavity 22 of the second container 12.

As shown in FIG. 12 and in a non-limiting example, the second direction of rotation 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 turn the first container 14 in the opposite direction of rotation F2 to move the closure 50 down until it falls into the inner cavity 22 of the second container 12. (not shown in the figures)

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

When using the device 10, in case the closure element 50 is in front of the open lower end 28 of the supply tube 24, said closure element 50 will be adjacent to the specified lower end 28 by its blocks 54e, thus allowing the mixture M contained in the second container 12 to flow. , between the blocks 54e in the first container 14 by turning said device 10 upside down.
