Technical Field
The present invention relates to the field of disposable deformable capsules containing cosmetic products, in particular cosmetic products intended to be added to a cosmetic mixture, in order to produce a cosmetic product that can be used by the user.
Background
According to a first prior art, proposed for example in european patent EP2038189, there is a known system for preparing individual cosmetics by means of predetermined metered quantities of pods containing different base products, the content of which is mixed with water in the machine after the pods are opened.
The opening of the pods cannot be calibrated against a rather limited force and therefore cannot be fully controlled in the case of a reduction in force and the subsequent pouring is not guided by the passage at the outlet of the pods, but this is not a drawback in patent EP2038189, since their contents are dispersed in the mixing chamber where the water is also mixed with the cosmetic product coming from the container.
According to a second prior art, described for example in us patent 4,759,472 or patent application FR2673916 or patent application WO2017/204257, a capsule is known which comprises a cosmetic pouch closed by a frangible wall having inwardly directed angular grooves, which, when opened, leaves the pouch and even the capsule, which can then be used directly without participating in the preparation of the mixture.
However, although the opening of the capsule has been more finely calibrated for the case of reduced force, once the frangible wall is broken, in other words opened, the cosmetic product will flow out of the capsule in a poorly controlled or even completely uncontrolled manner.
Disclosure of Invention
It is an object of the present invention to provide a deformable capsule which at least partly overcomes the above-mentioned disadvantages.
More specifically, it is an object of the present invention to provide a deformable capsule which is able to control the opening of the capsule well when the force exerted on the deformable capsule exceeds a given opening threshold, and which, after opening, suitably directs the outflow of the contents of the deformable capsule.
In fact, the present invention has found a double problem encountered with single-use deformable capsules having frangible walls. On the one hand, the opening is poorly controlled during the opening of the capsule, resulting in inadvertent tearing resulting in the ejection of the contents from the bag in an uncontrolled direction and intensity, or resulting in occasional absence of tearing, thus preventing the opening of the capsule and the outflow of the contents from the bag. On the other hand, once the contents flow out of the bag, their outward path is also uncontrolled, resulting in an unguided spontaneous ejection of the contents from the capsule.
The present invention aims to at least partially solve this dual problem. On the one hand, due to the presence of the concave angular shape (also called inwardly directed angular groove) in the frangible wall, and due to the separation of the two sheets forming the frangible wall by peeling, the opening will be better controlled during opening of the capsule. On the other hand, once the contents have flowed out of the bag, the outward path of the contents will be better controlled thanks to the presence of the guide channel forming a segment of narrower cross-sectional area and the connector at the end of the guide channel, wherein the channel enables the two capsules to be connected to each other in order to mix the contents of the two capsules together, forming the final ready-to-use product, the movement of the mixture between the respective bags of the two capsules through the narrower cross-sectional area between the two bags comprising the two connectors, advantageously carried out one or more times alternately in one direction and then in the other, preferably in a machine that alternately presses one of the two deformable capsules and then the other.
Thus, when two deformable capsules are joined together, the contents of one of them can flow first into the other capsule, and then the mixture can flow from one capsule to the other for better homogenization, while remaining within a pair of capsules without leaving the mixing chamber, which would foul the mixing machine. The pair of interconnected capsules can be used in machines for manufacturing cosmetic products, such as those described in patent application FR1755749, which is incorporated herein by reference.
Patent application FR1755749 describes a system for manufacturing a personalized cosmetic product from a predetermined dose of packaging units (also called pods), the mixing of the content of which is done automatically by a machine, the end consumer of which only needs to introduce the predetermined dose of packaging unit into the machine and collect the ready-to-use personalized cosmetic product. The mixing is done in a pair of interconnected capsules without touching the rest of the mixer and therefore without soiling the machine.
The specific internal structure of the disposable deformable capsules of patent application FR1755749 can be further modified in order to better control the opening of these deformable capsules so that they open whenever they need to be opened and therefore also do not open accidentally during their impact.
To this end, the invention proposes a capsule deformable at one time, comprising: a pouch containing a cosmetic product, the perimeter of which is formed by two sheets pressed against each other and fixed to each other; a channel connecting the bag to the outside of the capsule, forming a narrower cross-sectional area with respect to the bag; a frangible wall separating the pouch from the channel, having the shape of an inwardly directed angular groove within the shape of the other protrusion of the perimeter of the pouch, wherein rupture of the frangible wall caused by pressure exerted on the pouch is achieved by peeling two sheets pressed together and secured to each other at the inwardly directed angular groove, the rupture of the frangible wall placing the pouch in communication with the channel such that cosmetic flows from the pouch to the channel; a male or female connector for connecting the female or male connector of another capsule, having sufficient rigidity to ensure a sealed connection between the capsules once the connectors are connected to each other, the male or female connector being located at one end of the channel, opposite the other end of the channel located beside the bag, or at the opening of the channel, which is different from the end of the channel located beside the bag, the male or female connector opening to the outside of the capsule.
According to a preferred embodiment, the invention comprises one or more of the following features, which can be used alone or in any combination.
Preferably, the channel is a guide channel forming a constant or almost constant narrowing of the cross-sectional area relative to the bag over all or part of its length within plus or
The shape and size of the guide channel allows a better control of the passage of the mixture between the pockets of the capsule and a better homogeneity of the mixture when it is guided into and through the guide channel. This circulation advantageously takes place one or more times in one direction and then in the other direction.
Preferably, the perimeter of the bag is formed by two sheets welded to each other.
Thus, the presence of the weld between the two sheets allows the contents of the capsule bag to remain well isolated from the external environment, for a longer time and in a safer manner, reducing or even preventing leaks and accidental tears.
Preferably, the disposable deformable capsule further comprises two welding seams: a first weld seam extending around the bag while enclosing a majority of the channel; and a second weld seam extending around the pouch without closing off a substantial part of the channel, the second weld seam being at least partially, preferably completely, arranged inside the first weld seam, the second weld seam being more frangible than the first weld seam, the inwardly directed angular groove being established only by the second weld seam and not by the first weld seam.
Thus, when opening the capsule, during opening of the frangible wall, the direction of the contents of the bag flowing to the outside of the bag is better controlled and directed towards the guide channel, so that the contents then flow to another capsule towards another connected capsule.
Preferably, the second weld is more brittle than the first weld, the pressure threshold that will open the second weld being between 20% and 50%, preferably between 30% and 40%, of the pressure threshold that causes the first weld to rupture.
Thus, when opening the capsule, the direction in which the contents of the bag flow to the outside of the bag during opening of the frangible wall is even better controlled and better directed towards the guide channel, so that the contents then flow to another capsule already connected to the capsule. In this way it is easy to calibrate the pressure at which the second weld seam is almost opened, while the first weld seam is hardly torn off.
Preferably, when the rupture of the frangible wall occurs by peeling the two sheets welded to each other at the inwardly directed angular groove, the second weld is formed only by fusing the two outermost layers of the two sheets.
Thus, peeling is more easily achieved, further reducing the risk of accidental tearing which may result in the contents of the bag not being ejected completely from the capsule through the passage, thereby resulting in partial loss of these contents and improving the cleanliness and cleanliness of the opening of the frangible wall.
The specific structure of the weld seam created between the faces of the bag given below is particularly suitable.
Preferably, the weld seam has: the welding temperature is between 160 ℃ and 200 ℃, advantageously between 170 ℃ and 190 ℃, and/or the welding pressure is between 2bar and 6bar, advantageously between 3bar and 5bar, and/or the welding time is between 0.5 seconds and 3 seconds, advantageously between 1s and 2 s. When two different welds are present, this involves weaker or more brittle welds.
Preferably, the shape of the pockets of the capsule is circular in its median plane perpendicular to its thickness direction.
The circular shape thus ensures a better concentration of the forces for opening the capsule towards the inwardly directed angular grooves, enabling a better control of the opening of the capsule due to the balanced distribution of the forces over the circumference of the circular shape.
Preferably, the bag is flat, one of its two faces being flat, the other of its two faces being at least partially convex and flexible, so as to allow the contents of the bag to be expelled by mechanical pressure.
Thus improving the simplicity of using the capsule. On the one hand, when two capsules are arranged facing each other, the flat face of the bag allows a simple and uniform heating, even preferably a single heating element of simple structure advantageously having a constant thickness. On the other hand, the convex and flexible side of the bag provides a simple way to completely expel the contents of the bag from the bag by a simple mechanical pressure, even preferably with two mechanical members, such as pistons, arranged facing each other, each in turn responsible for exerting a pressure on one capsule to empty its contents towards the other capsule when the two capsules are arranged facing each other, and then vice versa.
Preferably, the convex shape further comprises a concave portion into which an inwardly directed angular groove enters.
Thus, when opening the capsule, during opening of the frangible wall, the direction in which the contents of the bag flow to the outside of the bag is better controlled and directed towards the guide channel, so that the contents are then directed towards another capsule already connected to the capsule.
The specific structure of the faces of the bag given below is particularly suitable.
Preferably, the convex surface is a thermoformed film, more preferably a monolayer, even more preferably a polyolefin, advantageously having a thickness of between 100 μm and 300 μm, more advantageously having a thickness of between 150 μm and 250 μm.
The thickness of the convex surface is, for example, 200 μm.
Preferably, the flat face is a flat and flexible film, more preferably multilayered, even more preferably formed by a stack of PET/aluminium/PP, advantageously with a thickness between 50 μm and 250 μm, more advantageously with a thickness between 100 μm and 200 μm.
The thickness of the flat surface is, for example, 150 μm.
The thickness of the flat face is preferably less than the thickness of the convex face.
Preferably, the pouch contains a predetermined amount of only one of the two phases, the mixture of which forms the ready-to-use cosmetic.
Thus, until the moment of use by mixing the two phases, each phase contained in one of the two capsules can be kept completely isolated from the other phase contained in the other capsule, thus allowing complete or almost complete absence of preservatives in the composition of the phases, each of these phases being natural, in other words, free or almost free of preservatives.
The specific structure of the faces of the bag given below is particularly suitable.
Preferably, the depth of the inwardly directed angular groove is greater than half the width of the angular groove and less than the width of the angular groove.
Thus, a good compromise is achieved between controlling the opening of the frangible wall and the minimum threshold required to open the frangible wall, reducing or even eliminating the risk of accidentally opening the frangible wall.
Preferably, in the first embodiment, the sheets are more firmly secured to each other for certain materials of the sheets pressed against each other, resulting in the frangible weld being somewhat stronger in nature, the width of the frangible wall of the inwardly directed angular groove being constant along the entire length of the frangible wall of the inwardly directed angular groove.
Thus, the manufacture of the inwardly directed angular groove is simplified and the reproducibility of its performance is better guaranteed, the other characteristics of the frangible wall of the inwardly directed angular groove or of the appropriate weld seam (thickness, width and depth, and shape) being sufficient to ensure that the frangible wall or the appropriate weld seam starts to open in the appropriate position of the inwardly directed angular groove with respect to the foremost part of its arm, without involving additional complexity including refining the width of the frangible wall, the appropriate position of the weld seam, the inwardly directed angular groove connecting it to the periphery of the capsule with respect to the foremost part of its arm. Thus, we obtain a clean and complete opening of the entire inwardly directed angular groove, including when the opening is caused by applying a calibration force, e.g. from the pressure of a mechanical piston on the deformable capsule, in which case the variable width of the frangible wall of the inwardly directed angular groove, is possible to open only partially and vary from one opening to the next.
Preferably, in the second embodiment, some other materials of the sheets pressed against each other are less firmly fixed to each other, resulting in a brittle weld seam that is inherently somewhat less strong, so the width of the brittle walls of the inwardly directed angular groove is greater at the frontmost part of the inner corner recess than at the arms of the inwardly directed angular groove.
Thus a reproduction of the properties of the inwardly directed angular groove is better ensured, the variable width of the frangible wall of the inwardly directed angular groove decreasing from the foremost part towards the arm, helping to better ensure that the frangible wall, or the weld in place, starts to open at the appropriate position of the foremost part of the inwardly directed angular groove. Thus, even in this case, a clean and full opening of the entire inwardly directed angular groove can be obtained, including when opening by applying a calibrated force, for example a force from the pressure of a mechanical piston on the deformable capsule.
Preferably, the width of the frangible wall of the inwardly directed angular groove is between 1mm and 2.5mm, preferably between 1.5mm and 2 mm.
Preferably, the inwardly directed angular groove has a pointed shape with an inwardly directed point, preferably a V-shape, more preferably a V-shape where the angle at the point is acute.
Thus, if the point is narrower, the opening pressure exerted on the deformable capsule is positioned more at the cusps of the inwardly directed angular grooves.
Preferably, the frangible wall is dimensioned in its thickness, width, length and shape such that it opens when a force is exerted on the pouch of between 10N and 45N, preferably between 15N and 40N (N ═ newtons).
Other features and advantages of the present invention will become apparent from a reading of the following description of the preferred embodiments of the invention, given by way of example, and with reference to the accompanying drawings.
