Description

Packaging and dosing device.

The present invention aims at a packaging device of a product suitable for flow and provided with a means to dose the quantity of the product dispensed. In particular, the present invention applies to the packaging and dosing of a cosmetic product.

By "cosmetic product", a product as defined in Council Directive 93/35 / EEC of 14 June 1993.

Simple packaging devices are known that they comprise a package in which a product is packaged, comprising the container a neck that contemplates an opening to allow the distribution of said product. Generally, said container is it closes by means of a plug removably mounted on said neck. Devices of this type do not allow effective dosing Small quantities of product. Indeed, the distribution of product is obtained by putting the container upside down, so that the product flows by gravity.

Sometimes these packaging devices are provided with a measuring cup to allow dosing the quantity  of the distributed product to use. In the cases in which these devices are sold inside a box, the glass Dispenser is included inside the box. In particular, this glass dispenser can be mounted on the device, in particular around the cap such that the side walls of the vessel dispenser surround that cap, until contacting the outer perimeter of the container. Examples are described in the WO 2005/002984, US 5,361,054 and EP 0261713.

The plug is generally tight on the container and therefore carried in rotation with respect to the latter, while the dosing vessel moves by translation around the cap. In cases where the dosing vessel is it attaches on the plug, the necessary tensile force employed by the user to separate the dosing vessel must be weak enough to be able to do it manually. In fact, it is essential to mount the measuring cup on the cap, only after the latter has tightened on the container.

In the factory, the manufacture of said devices is slow and expensive since it requires a high number of  handling stages

The invention aims to propose a device for packaging and dosing that is practical to use and Low construction cost.

The object of the invention is also a product packaging device, particularly cosmetic, which understands

-

a container containing said product,

-

a closing member suitable for closing an opening of the container,

-

a receptacle for receiving a dose of said product when said opening is unlocked, the receptacle being mounted so removable on said closure member, the receptacle on the closure member to provide a zone lateral pressure on the closure member, characterized in that  the receptacle comprises an opening (18), such that in position mounted on the closure member, said closure member covers the access to this opening and between the receptacle and said member of closure is provided a drying vent (25), the vent drying is formed by a local interruption of a gallon (23) formed on the inner perimeter (21) of receptacle (4).

In this way, the lateral grip zone allows to manipulate in a single stage the unit formed by the receptacle mounted on the closure member. This unit is assembled in such a way that the tensile force necessary to separating the receptacle from the closure member is at least 15 N. The measurement of this tensile force is carried out by exerting a longitudinal tensile force on the receptacle at a speed of 120 millimeters per minute, keeping the member of closure in fixed axial position. With such a hitch, the separation of receptacle of the closure member can be made manually, and This unit remains intact during factory transport by vibrating devices.

Advantageously, the assembly means of the receptacle on the closure member are selected in such a way that the tensile force to be exerted to separate the unit it is less than 40 N such that on average all users manage to manually separate the receptacle from the member of closing.

In mounting position on the member of closure, said closure member may cover an opening of the receptacle for which a dose of product is received. Of this mode the inner perimeter of the receptacle that defines a volume useful, used to receive a dose of product, is protected from risks of external contamination during storage of receptacle on the closure member.

In particular, the closing member can comprise a bottom wall comprising a first face from which rises a suitable mounting skirt to cooperate with the container neck, presenting the outer perimeter of the skirt of mounting said grip zone. In this case the opening of the receptacle can be covered by the bottom wall.

For example, this background wall can comprise a relief, presented on a second face opposite to the first, suitable to cooperate with the receptacle to ensure the assembly of the latter on said closing member.

For example, the receptacle can be held by ratcheting on the closure member. Alternatively, you can be held tightly over said closure member.

When the receptacle and said closure member are mounted, a drying vent is provided between both of them. In this way, even if in the receptacle walls a residual amount of product or water remains when it becomes to be mounted on the closure member, the vent allows a flow of air inside the receptacle to allow evaporation of those residual liquids and that there is no condensation on the walls. This prevents the risk of developing molds or Bacteria in the receptacle.

Another advantage of this vent is that the assembly and disassembly of the receptacle with respect to the closure member it is also facilitated to the extent that no overpressure is created in the receptacle during assembly, nor pressure during disassembly

The receptacle can also include advantageously a useful reference for dosing, in Particular a graduation. Preferably, this reference is to distance from the edges of the receptacle opening so that a desired amount of the product.

For example, the closing member may Hold tight on the neck.

In particular, a neck of the container may be provided with a flow reducing means, for example coupled to the force inside said neck. In this case, the member of closure may comprise a shutter peak suitable for enter a hole of this flow reducing means. In in particular, the passage provided by the flow reducing means it can decrease at least 30% and preferably at least 50% the passage defined by the neck of the container in the absence of this reducer. The size of these steps is calculated at the level of one cross section of the neck of the container.

The object of the invention is according to another of its aspects, a product packaging device, particularly cosmetic, which comprises

-

a package containing said product and comprising an opening equipped with a flow reducing means for the distribution of said product,

-

a suitable closing member to close this opening,

characterized because it comprises a receptacle for receiving a dose of said product when this opening is unlocked, mounting the removably receptacle on said member of closing.

With such a device, the invention allows palliation the drawbacks of the caps that comprise an internal skirt dosing, in addition to a mounting skirt, being arranged this dose skirt inside the neck when the cap is mounted on the container. The invention allows provide a closure member that remains tight and maintains the quality of the capping during the use of the device.

The object of the invention is particularly the use of a device according to the invention for the packaging of a cosmetic product, particularly a product Active for skin treatment.

The invention will be better understood from the reading the following description and examining the figures attached. These are presented for indicative purposes only and never limiting the invention. The figures show:

- Figure 1: a profile view of a device according to the invention;

- Figure 2: a longitudinal section view of a device according to the invention;

Figure 1 shows a device 1 that comprises a container 2 closed by a closure member 3 on the which is mounted a receptacle 4. Representing the device 1 in assembled position in figure 1. The device 1 comprises a longitudinal axis X, so that an opening is defined (not visible) of container 2 substantially transverse to this axis longitudinal X. The container 2 extends to the lake of this axis longitudinal X. The container 2 is for example cylindrical and comprises a neck 5 that exceeds the length of the X axis, likewise cylindrical, but of lower section than that of container 2.

In Figure 2, neck 5 of container 2 defines opening 6 of container 2. In particular, the outer perimeter of the neck 5 has a thread 7. The closure member 3 comprises a bottom wall 8 from which a mounting skirt 9 protrudes which presents a complementary thread 10 so you can removably mounted on the neck 5. The perimeter outside of the mounting skirt 9 defines a lateral clamping zone  which allows the manipulation of the closing member 3, in view of its assembly as of its disassembly on the neck 5, the receptacle 4 is or is not mounted on this closure member 3.

In the factory, the clamp that holds the member of level closure of this lateral grip zone can move the closure member 3, topped by its receptacle 4, above the container 2 such that the axis of rotation of this clamp is superimpose substantially that of the X axis.

In particular, inside the neck 5 is a nozzle 11 mounted. In particular pressure mounted. To this effect, comprises a transverse wall 12 that is mounted of butt with a perimeter 13 of the neck 5. Of this transverse wall 12 protrudes a skirt 14 forcibly coupled in the inside of the neck 5. The transverse wall 12 comprises a hole 15 that allows product distribution with a flow relatively reduced with respect to the flow that would have been obtained, in the same conditions, through the opening 6 of said neck 5. The section of this hole 15 is for example lower than the minus 30%, and more particularly at least 50%, at internal cross section of the opening 6. The nozzle 11 is a flow reducing medium.

When the closing member 3 is mounted on neck 5, a peak 16 that exceeds the bottom wall 8 is enter through this hole 15 to ensure a hermetic plug of said hole 15.

The outer perimeter of the closure member 3 holds the receptacle 4. In particular, the receptacle 4 is of substantially cylindrical shape such that when the receptacle is mounted on the closure member 3 is presented an edge 17 of the opening 18 of this receptacle 4 against the outer perimeter 19 of the back wall 8. The contact between the edge 17 and the bottom wall 8 is not airtight.

The bottom wall 8 comprises a relief 20 suitable for cooperating with the receptacle side walls 22 4. As depicted, relief 20 is configured to be introduced by ratchet inside the receptacle 4 and to cooperate with the inner perimeter 21 of these walls lateral 22.

In particular, as can be seen in the Figure 3, the inner perimeter 21 of the receptacle 4 has a gallon 23 at least in annular part intended to cooperate for ratcheting with the complementary relief 20 here in the form of Dome. The dome is partly inserted into receptacle 4 in assembled position

According to embodiments of the relief 20, the latter can cooperate with the outer perimeter of side walls 22. In another variant, this relief 20 can form a groove in the bottom wall 8 so that there it receives the edge 17 of the receptacle, and cooperation with the side walls 22 for mounting on the closure member 3 on the inner and / or outer perimeter.

In Figure 4, the mounting skirt 9 exceeds a first side of the back wall 8, when the relief complementary 20 exceeds a second side, opposite the first, of this same bottom wall 8. In assembled position, edge 17 of receptacle 4 rests against the radially outer perimeter of relief 20. Relief 20 emerges relatively from the wall of the bottom 8 in such a way that it is surrounded by one against kicks off 24 in which the gallon 23 is introduced. The counter kicks off 24 of the relief 20 is preferably annular.

To allow a flow of air inside of the receptacle when the latter is mounted on the member of closure 3 is provided an aeration vent 25. In a mode particular embodiment represented in the figures, the vent 25 is obtained in part by a local interruption of the gallon 23.

\hbox{fondo 8.}

Alternatively, the vent 25 can be produced by a pore formed through the side wall 22. In this case, the pore has a defined cross-section depending on the viscosity of the product so that the latter cannot flow through said pore, even by gravity under normal conditions of use. This pore has for example a cross section of less than 1 mm2. It is for example less than 10% of the section of the opening 18. This pore is preferably made close to the edge 17. At the level of this interruption, the thickness of the side wall 22 is reduced so that it forms a notch 26 backwards with with respect to the gallon 23, but also backwards with respect to the inner perimeter 21. This notch 26 extends along the X axis, above the height of the gallon 23 along this X axis. In this way the channel of air provided by this vent 25 flows into the receptacle housing when mounted on the bottom wall 8. On the other hand to avoid any plugging.
To this air channel, a release 27 of the edge 17 is also provided, such that in the assembled position, an air passage is provided, even if in the mounted position the edge 17 abuts against the wall of

 \ hbox {background 8.} 

In a particular embodiment of the member closure 3, figure 4, the latter comprises an annular skirt 28 arranged concentrically inside the mounting skirt 9, this annular skirt being 28 in length, along the X axis, less than the length of peak 16 along this same axis, this annular skirt 28 being provided to reinforce the wall cross section 12 of the nozzle 11 in the closed position. This way, the introduction of the nozzle 11 in the neck 5, and therefore the sealing of the closure, since the member Closure 3 is pressed against the neck until the skirt ring 28 fits against the nozzle 1. This ring skirt 28 ensures the closure of the container by tolerating variations in manufacture of the container and the closure member.

According to a variant of the embodiment no represented, the closure member may comprise a support that presents the mounting skirt 9 and therefore the grip zone side, and a rotating distribution nozzle with respect to to the support between at least one closing position and a position of distribution in which the support holes and the nozzle of Distribution match. In said variant, the support may be fixed mounted on the container 2, for example by ratcheting, and the Closing member 3 may be a "service capsule."

In another variant, the mounting of the receptacle on the closing member can be done by cooperation between the side wall 22 of the receptacle and the outer perimeter of the mounting skirt 9. In this case, the mounting is such that the wall side 22 only covers a part of the perimeter of the outside of the mounting skirt 9 to provide at least two areas of different grip for factory handling of the member of closure 3, these two grip zones are preferably diametrically opposed. For example, the edge 17 of the receptacle 4 can comprise two diametrically opposed recesses for provide lateral clamping zones of the closure member 3, when mounted on the latter.

Preferably, the edge 17 of the receptacle 4 is at a distance from the edge 31 of the mounting skirt 9, such so that an annular grip zone of the member of close 3, between this edge 17 and the edge 31.

The user of device 1, according to the invention separates receptacle 4 from closure member 3. Then separate the closure member 3 from the neck 5 and present the hole 15 below receptacle opening 18 4. Product flows then due to gravity and / or due to pressures exerted on the walls of the container 2, when the latter can deform. Preferably, the user resets the container 2 as soon as the liquid level in receptacle 4 reaches a reference level 29. Finally, the user extracts the product from receptacle 4 by means of an application member, for example a cotton.

Reference level 29 is marked by example around the contour of the receptacle 4 by a annular indication, materialized in this case by a ring 30 which protrudes from the outer perimeter of the side wall 22. In in particular, receptacle 4 delimits a volume such that the dose of product that can be identified thanks to reference level 29 It is of the order of 3 ml.

In the case where the receptacle comprises a pore to form the vent 25, is performed for example between the reference level 29 and edge 17.

In particular, at least the closing member 3, the receptacle 4 and the nozzle 11 are obtained by molding from of thermoplastic materials, in particular from materials polyolefins such as polyethylene or propylene. They can also Obtained from thermostable materials such as resins of phenol urea, in particular bakelite. The container 2 is manufactures for example glass or also by molding from a thermoplastic material

Container 2 contains, for example, a solution. for skin care.
