Description

PACKAGING SUITABLE TO CHANGE ¹ ASPECT

The invention relates to packaging comprising one or more expressive and / or decorative visual structures and more particularly to such an empty packaging or filled with its contents (primary packaging) and its manufacturing process.

The invention typically relates to packaging which is rigid or semi-rigid containers for perfumery, parapharmacy, or cosmetic products, comprising one or more point, elongate or surface visual structures for the purpose of expressing - for example, nature , the origin, the destination, the use of the content, its brand, the price ... - and / or the ornament - for example a color, a combination of colors, transparency or opacity

Such visual structures have, on the one hand, to be visually different depending on an activation control applied to the package and, on the other hand, to be visually observable from outside the box. packaging in at least one state activated or deactivated.

The invention also relates to packaging which is rigid or semi-rigid containers for products analogous to perfumery, parapharmacy or cosmetic products, with regard to the packaging requirements or the consistency or the use or the destination.

Such packages are typically pots, flasks, sprayers, spray bottles, applicators, dispensers, tubes, boxes, boxes, sticks ... or parts or subassemblies thereof.

It may also be similar packaging in terms of their design, their arrangement and the requirement of such visual structures, for products in the fields of luxury, the arts of the table, the food industry , computer science, communication, telecommunications, Internet, video, games and toys, stationery, gifts ...

The document FR-A-2908502 describes a package comprising a bottle, one or more light sources, automatic ignition means of this light source, and a wall comprising a transparent layer. This transparent layer is capable of longitudinally transmitting light within its thickness. The light source is arranged with respect to this transparent layer so that the light it emits can propagate longitudinally within it. The transparent layer and the light source are adapted so that at least a portion of the light propagated longitudinally within the transparent layer can be diffused outside the bottle so as to produce a light effect. Such a package has the constraint - and therefore the limit - of requiring a wall comprising a transparent layer capable of longitudinally transmitting light within its thickness.

US 4723656 discloses a package, namely a blister in two parts (a wafer and a transparent shell) for the presentation and sale of batteries (batteries). This package includes a voltage indicator attached to the inner face of the shell, seen from the front of the package. The voltage indicator is ribbon shaped with two electrical contacts associated therewith. It comprises an electrically conductive but heat conducting support member, an electrically resistant member, and a layer of thermochromic material located on one side and the other of the support member. The element electrically resistant to a cross-sectional area increasing from one end to the other, so that a temperature gradient develops longitudinally when powered electrically. The layer of thermochromic material is in thermal contact with the electrically resistive element, although separated from it by the support member. In one embodiment, the package must be open for a battery to be placed in the desired position. 'trial. Then, the battery is replaced in its cell. In other embodiments, the batteries remain permanently in their cells and it is intended to push the contacts of one or the other of the batteries to ensure electrical contact with the battery terminals and the flow of current Electric element in the electrically resistant.

According to US 4723656, the contents of the package is the power source of the voltage indicator, the packaging not allowing and not intended to receive other content. Such a package can not therefore receive a content such as a perfumery, parapharmacy, cosmetic, or the like, as indicated above. On the other hand, the voltage indicator is reported on the inner face of the shell with a substantial thickness which is not a problem for the intended application but is unacceptable in the case of the packaging of a product of perfumery, parapharmacy, cosmetic, or the like, as indicated above. Also, the power source (the batteries) is visible from the outside of the package, which is justified when it is the actual content of the package, but is prohibitive for a content such as a product. perfumery, parapharmacy, cosmetic, or the like, as indicated above. Finally, the visible effect provided by the voltage indicator is limited to a section of ribbon, which does not offer the versatility of a visual effect aimed at the expression and / or the ornament adapted to a product. perfumery, parapharmacy, cosmetic, or the like, as indicated above.

In which, according to the wishes, the visual structure may be visually different reversibly or otherwise, ephemeral or durable.

In which the power supply means are not visible from the outside of the package.

In which the handling and implementation of the packaging by the user are not affected as a result of the existence or the visual structures and means for the or to achieve them. For example, because the shape, the dimensions, the ergonomics, the mode of use of the package do not have to be substantially modified or adapted and because the size of the functional assembly comprising a support surface, one or more heating layers, one or more thermochromic layers does not constitute an inconvenience, in particular because it does not create substantial extra thickness with regard to the size of the package.

The cover 7 or its fixed part or its mobile part has an orifice 7a adapted to correspond with the orifice of the dispensing pump 15a, and by which the certain content C is dispensed when, in a manner or a other, the movable actuating member 15c is actuated.

The outer face 11b of the end portion 8 of the outer and peripheral wall 5 facing the inner face 7b of the cover 7 and the inner face 7b delimit a cavity 16, forming part of the spray bottle 1. The interior of the cavity 16 is here invisible from the outside E, the cover 7 being opaque.

The spray bottle 1 also comprises a support means 17, rigid, plate-shaped. This support plate 17 has a central recess 17a and is limited by an outer peripheral edge 17b. It is of a shape and a size and it is arranged so as to be carried by appropriate carriers - such as reliefs, hollows, pins, screws, glue. . - formed on the outer face 11b of the outer and peripheral wall 5 and / or on the inner face 7b of the cover 7, being placed in the cavity 16, the recess 17a allowing the passage of the neck 10. In a possible embodiment , the support plate 17 simply rests on the shoulder, forming a bearing projection, of the end portion 8.

According to possible embodiments, the outer and peripheral wall 5 is rigid or semi-rigid and made of a substantially electrically insulating material. For example, the outer and peripheral wall 5 is made of a molded thermoplastic synthetic material selected from a polyolefin, a vinyl polymer, a polyamide, a polystyrene, a polycarbonate, a polymethacrylate, a polypropylene. Or, for example, the outer and peripheral wall 5 is glass. According to other embodiments, the outer and peripheral wall 5 comprises a substantially electrically conductive material, coated with a layer of substantially electrically insulating material.

Each support face 18 has a single substantially electrically insulating zone 18a or it comprises several substantially electrically insulating zones 18a. Insofar as a support face 18 is substantially electrically insulating, the substantially electrically insulating zone 18a coincides with the support face 18. If, on the other hand, a support face 18 is substantially electrically conductive, a substantially electrically insulating zone must be provided. 18a which does not necessarily merge with the support face 18

In the particular embodiment considered, there is provided a support face 18 constituted by a part or the whole of the outer face 11b of the body portion 9 and containing the outer and peripheral wall 5, which wall 5 is made of a material substantially electrically insulating or substantially electrically conductive material but coated with a layer of substantially electrically insulating material.

In other embodiments, a support face 18 is constituted by a part or the entirety of the inner face 11a. In still other embodiments, a support face 18 comprises all or part of both the outer face 11b and the inner face 11a. In still other embodiments, a support face 18 is distinct from both the outer face 11b and the inner face 11a, but is attached to one or the other of these in a fixed and rigid manner with immobilization, to be thus integrated with the face 11a, 11b.

The spray bottle 1 may comprise one or more heating layers 19. And it may comprise one or more thermochromic layers 20.

The support face (s) 18, the heating layer (s) 19 and the thermo-chromic layer (s) 20 form part of, respectively, one or more assemblies 18, 19, 20 making it possible to produce the visual structure (s) 2, together with the power supply means and the control means, reason why this or these sets are qualified as "functional". Such a functional assembly 18, 19, 20 is structurally integrated, of manufacture. By this is meant that during the manufacture of the spray bottle 1 - as it is the manufacture intended for the spray bottle 1 to have a changing appearance -, the support surface (s) 18, the one or more heating layers 19 and the thermo-chromic layer or layers 20 are united, associated and incorporated together to form an indissociable coherent whole. On the other hand, such a functional assembly 18, 19, 20 is structurally integrated, manufacturing to the outer wall and peripheral 5. This means that during the manufacture of the spray bottle 1, the functional assembly 18, 19, 20 and the outer and peripheral wall 5 are united, associated and incorporated together and to the spray bottle 1 to form an inseparable coherent whole.

In the particular embodiment considered, such a functional assembly 18, 19, 20 is fixedly and rigidly supported with immobilization by the outer and peripheral wall 5, and is integrated in its outer face 11b. The functional assembly 18, 19, 20 is therefore located on the side of the outer face 11b and is in contact with it. It is located outside E and outside the inner enclosure 6. In other embodiments, a functional and structurally integrated assembly 18, 19, 20 is located, conversely, on the side of, in contact with or near, the inner face 11a of the outer and peripheral wall 5, inside the inner enclosure 6.

On the other hand, such an assembly 18, 19, 20 is without substantial extra thickness with regard to the size of the spray bottle 1. The term "without substantial extra thickness" means that for a user or an attentive observer the thickness of the assembly 18, 19, 20 is undetectable or virtually undetectable, does not interfere or almost no gripping, handling and use of the spray bottle 1. In the case of a spray bottle 1 for perfumery, means " without substantial extra thickness' with respect to the size of the spray bottle 1 a thickness of the order of less than 1 mm, in particular of the order of less than 500 microns, more especially of the order of less than 250 microns.

A heating layer 19 has an outer face 21a and an inner face 21b. A heating layer 19 is substantially able to allow the raising of its temperature and the heat transfer at least from its outer face 21a. For this purpose, a heating layer 19 is substantially electrically conductive and resistive, being made of or comprising one or more materials suitable for this purpose and it is intended to make it travel for this purpose by an electric current.

A heating layer 19 has a first continuous and predetermined shape and has two ends 22 forming an electrical contact. The inner face 21b of a heating layer 19 extends over, in contact with, and secured to a substantially electrically insulating zone 18a, in a fixed and rigid manner with immobilization.

A heating layer 19 constitutes with and between its two ends 22 an electrical activation circuit able to heat up by Joule effect in case of circulation of an electric current.

A thermochromic layer 20 has an outer face 23a and an inner face 23b. It is in substance adapted to that its optical state varies according to its temperature. For this purpose, it is intended to heat it by means of a heating layer 19. A thermochromic layer 20 is made of, or comprises, one or more thermochromic materials adapted to the desired visual appearance.

A thermochromic layer 20 has a second continuous and predetermined shape. The inner face 23b of a thermochromic layer 20 has one or more zones of changing appearance 23c, turned towards and located near the outer face 21a of the heating layer 19. Thus, in a changing appearance area 23c, a thermochromic layer 20 is adapted to receive the heat transferred by the outer face 21a of the heating layer 19. A zone of changing appearance 23c is an area of the thermochromic layer 20 in which the temperature rise caused by the heating layer 19 is sufficient to ensure a change in visual appearance. Typically, a zone of changing appearance 23c is located in contact with, or in the immediate vicinity of, the outer face 21a of the heating layer 19. For example, it is a zone located at right, vertically, in covering, the heating layer 19.

In the particular embodiment considered, the inner face 23b of a thermochromic layer 20 extends on, in contact with and secured to the outer face 21a of the heating layer 19, fixed and rigid manner with immobilization. This structure ensures the best heat transfer between the heating layer 9 and the thermochromic layer.

In this embodiment, the one or more functional and structurally integrated assemblies 18, 19, 20 are on the one hand located on the side of, in contact with or near the outer face 11b of the outer and peripheral wall 5, on the outside of the inner chamber 6, and secondly each of them has a structure whose order is support face 18 / heating layer 19 / thermochromic layer 20

With such an embodiment, the certain content C may be in contact with the inner face 11a of the outer and peripheral wall 5 or the free face of a layer or coating - or a set of layers or coatings - worn by this face 11a.

In other embodiments, the one or more functional and structurally integrated assemblies 18, 19, 20 are located on the side of, in contact with or near the inner face 11a of the outer and peripheral wall 5, within the same interior. In these embodiments, the outer and peripheral wall 5 is transparent or translucent, in a certain way. And in these embodiments, the visual structure 2 is visible from the outside E of the spray bottle 1, either on the side where is the assembly 18, 19, 20, or even, possibly, on the opposite side to the condition that the certain content C is also translucent or transparent. With such embodiments, the certain content C may be in contact with the inner face of the functional and structurally integrated assembly (s) 18, 19, 20 or the free face of a layer or coating - or a set layers or coatings - carried by this inner face.

On the other hand, instead of a structure of an assembly 18, 19, 20 according to the support surface 18 / heating layer 19 / thermochromic layer 20, the order may be support face 18 / thermo layer -chromic 20 / heating layer 19.

It is understood that the various embodiments envisaged can be combined in the same spray bottle 1, which contributes to obtaining an infinite range of visual aspects.

The spray bottle 1 also comprises electrical supply means 24 including at least one power supply 24a. These power supply means 24 are able to ensure the power supply of the heating layer 19, and this according to an activation command corresponding to an activated state or a deactivated state, respectively. The source or sources 24a of power are housed in the cavity 16. They are not in the inner chamber 6, which is intended to receive and contain the certain content C, but not the source or sources of power 24a. Activation control means 25 are associated with the power supply means 24 and are responsive to an activation command.

An expressive and / or decorative visual structure 2 has a third shape that is at least substantially that of the changing aspect area 23c. In other words, such a third form corresponds to the superposition shape of a heating layer 19 and a thermo-chromic layer 20. Therefore the search for an expressive and / or decorative visual structure 2 of a third desired shape determines the shape to be given to the first form with respect to the heating layer 19 and the second form with respect to the thermo-chromic layer 20. An expressive and / or decorative visual structure 2 a a different color and / or transparency according to the activated or deactivated state of the control means 25 (and therefore that the power source or sources 24a supply or not the heating layer electric current), and that the material thermochromic is or not at a temperature above its temperature threshold of color change and / or transparency. The rise in the temperature of the thermochromic layer 20 is obtained as a result of the rise in temperature of the heating layer 19, itself obtained by passing the electric current, thanks to the power supply means 24.

According to one characteristic of the invention, the thermochromic layer (s) 20 and / or the visual structure (2) are observable from outside the outer face (11b) of the outer and peripheral wall (5), at least in one of the two states enabled or disabled.

The spray bottle 1 also comprises two electrical connection terminals 26, intended to be electrically connected to the electrical contact ends 22. The two electrical connection terminals 26 are fixedly and rigidly carried with immobilization, of manufacture (in the sense explained above). ), by the outer and peripheral wall 5, being integrated in at least one of its two faces 11a, 11b and being arranged against it, without substantial extra thickness with respect to the size of the package, this feature in front of be in the same sense as the identical characteristic mentioned for the sets 18, 19, 20.

In the more specifically considered embodiment, the two electrical connection terminals 26 are carried by the body portion 9 and containing, more particularly by the side portion 13 and the outer face 11b. They are adjacent to the protruding ridge 14 and protrude beyond it, facing the end portion 8 forming a collar 10

Such electrical connection terminals 26 are for example metallic in a material such as copper or another metal or electrically conductive metal alloy. They are, for example, bonded to the outside face 11b of the wall 5. In the example shown, these two terminals 26 are formed of two thin copper plates (having for example a thickness of the order of 50 μm) serving of male plugs for electrical connection.

The power supply means 24 comprise, in addition to the power supply source or sources 24a, electrical connection means 27 and two electrical connection terminals 28, the latter being capable of and intended to be electrically connected to the two terminals of the electrical connection. electrical connection 26.

The support plate 17, which can form a printed circuit, supports the power source or sources 24a, the electrical connection means 27 and the electrical connection terminals 28, the latter being located HERE on its outer peripheral edge 17b. This outer peripheral edge 17b in the vicinity of the electrical connection terminals 28 and the electrical connection terminals 28 are arranged to be complementary to the electrical connection terminals 26, so that physical and electrical contact can be ensured between them during assembly. of the spray bottle 1. For example, in the embodiment more particularly considered, the electrical connection terminals 28 are arranged in female recesses of the outer peripheral edge 17b adapted to receive the pads of the male electrical connection terminals 26. With such a structure, the physical contact and the electrical connection between the two electrical connection terminals 26 and the two electrical connection terminals 28 are made for example by sliding the support plate 17 or the cover 7 which bears it with respect to the body part 9 and container.

The support plate 17 being placed in the cavity 16 whose interior is not visible from the outside, the power source or sources 24a, the electrical connection means 27 and the electrical connection terminals 28 are not visible from the outside of the spray bottle 1. The same is true of the electrical connection terminals 26.

In the case where the functional and structurally integrated unit (s) 18, 19, 20 are located on the side of, in contact with or near the inner face 11a of the outer and peripheral wall 5, inside the same 6, it can be provided that the power supply of the heating layer 19 is made via a connection passing through the outer peripheral wall 5, the rest of the electrical circuit being produced as described, the support plate 17 being placed in the cavity 16 whose interior is not visible from the outside. Alternatively, it can be provided that the power source or sources 24a are placed in a cavity forming a reserve formed in the inner chamber 6, arranged not to affect the enclosure 6 or filling and emptying of certain content C.

In the particular embodiment under consideration, the activation control means 25 is a switch connected to the at least one power source 24a. Such a switch is adapted for, in the open position (corresponding to the deactivated state), isolating the two ends 22 forming electrical contacts of the heating layer 19, respectively the electrical connection terminals 26, of the power source or sources electric 24a. It is adapted for, in the closed position (corresponding to the activated state), electrically connect the power source (s) 24a to both ends 22 of the heating layer 19, via the connection terminals 26 and 28.

In a possible advantageous embodiment allowing the visual structure (s) 2 to provide a more powerful visual effect, the electrical power supply means 24 furthermore comprise an electrical capacitance 29, connected in series with the power supply source (s) 24a between those and the electrical connection terminals 28. This capacitance 29 is also carried by the support plate 17 and housed in the cavity 16.

In the particular embodiment considered, the switch 25 is actuated by the movable actuator 15c. For example, the switch 25 may be formed of a flexible blade extending above and away from a terminal of the source power supply 24a, such that this flexible blade can be moved towards and to contact with this terminal by the movable actuating member 15c which comprises a tab 15d coming into contact with this flexible blade when it is itself in order to dispense the content C. As a consequence, when the movable actuating member 15c is actuated for the purpose of dispensing the certain content C, the two connection terminals 28 are powered by the power source or sources 24a, via the capacitance 29.

In other embodiments, the switch 25 is actuated by a maneuver made during the opening of the package or by this opening itself. Other facts or trigger actions may be considered.

On the one hand, it can be provided only one or more visual structures 2, without limitation of number. On the other hand, this or these visual structures 2 may have both a point, line or surface shape or a combination of such shapes, these shapes being simple or complex on the contrary, if necessary of a very great complexity. These shapes may have a straight edge or a more or less blurred outline and blurred For this purpose, it is sufficient to organize the relative arrangement of the support face or faces 18, the heating layer or layers 19 and the one or more thermo-chromic layers 20, their superposition defining the shape of the visual structure 2. Finally, as indicated, the visual structure (s) 2 can be on the inner side I and / or on the outer side E.

According to possible embodiments, a visual structure 2 is at least partly visually imperceptible by the user in the inactivated state and visually perceptible in the activated state or, conversely, it is at least partly visually perceptible in the state inactivated and visually perceptible in the activated state.

According to possible embodiments, a visual structure 2 is of reversible visual appearance or, on the contrary, it is of irreversible visual appearance. To do this, simply choose an irreversible thermo-chromic ink or varnish. For example, this irreversible modification can be activated at the first opening of the package 1, meaning that it has been opened.

In the particular embodiment considered, the support face (s) 18, the heating layer (s) 19 and the thermo-chromic layer (s) 20, as well as the complementary layer (s) integrated in the assemblies 18, 19, 20, which will be discussed by following, as well as the set or sets 18, 19, 20, the one or more areas of changing appearance 18a or the expressive and / or decorative visual structure (s) 2 are carried by the body portion and containing 9, namely the lateral part 13. However, nothing prohibits to provide that they are worn, alternatively or cumulatively, by the bottom end portion 12.

Several possible embodiments of an assembly 18, 19, 20 are now described.

In a first possible variant embodiment, illustrated in FIG. 6a, an assembly 18, 19, 20 also comprises, on the side of the internal face 21b of the heating layer 19 and on the side opposite to the thermochromic layer 20, and at least in line with the region of the changing appearance zone 23c, a thermally insulating thermal confinement layer 30.

In a second possible embodiment, corresponding to the particular embodiment considered and more particularly described above, in an assembly 18, 19, 20 and at least in the region of the changing appearance zone 23c, the heating layer 19 and the thermochromic layer 20 extend mutually on one another, the outer face 21a of the heating layer 19 and the inner face 23b of the thermochromic layer. 20 being one in direct contact with each other and secured to one another. Such a structure is such that a maximum of heat from the heating layer 19 is transferred to the thermochromic layer 20.

On the contrary, in a third possible embodiment, illustrated in Figure 6b, an intermediate layer 31 is interposed between the outer face 21a of the heating layer 19 and the inner face 23b of the thermochromic layer 20. In this case these faces 21a, 23b are not in direct contact with each other in the area of changing appearance 23c. In such an alternative embodiment, this intermediate layer 31 is substantially thermally non-insulating and substantially electrically insulating and / or colored.

According to the desired visual aspects, the layers 18, 19, 20, 30, 31 and 32 of such a plurality of layers have functional properties - relative to the visual structures 2 to be produced - which are similar or on the contrary different.

According to the desired visual aspects, the layers 18, 19, 20, 30, 31 and 32 of such a plurality of layers are juxtaposed, being then either adjacent or otherwise spaced, or they are superimposed, or they are at the same time. once juxtaposed and superimposed. According to the desired visual aspects, each of the 18, 19, 20, 30, 31 and 32 is of the same constant thickness for the same dispensing bottle 1 or, conversely, it is in several thicknesses varying continuously or not.

Similarly, it is possible to provide single electrical supply means 24 and / or activation control means 25 or, on the contrary a plurality of such means 24 and / or 25. The various heating layers 19 possibly provided may be supplied by the same power supply means 24 and / or activation control means 25 or, conversely, a plurality of such means 24 and / or 25.

Now more specifically, the production of a heating layer 19 is described.

Such a heating layer 19 may be made of a material such as an ink, an adhesive, a varnish or a material loaded with metal conductive particles and / or graphite. It can be performed by screen printing. It may have a thickness of less than 100 μm, more especially between 2 μm and 25 μm, for example of the order of 10 μm. It can have an electrical resistivity greater than 3.10 ^"6 Ω.m.

According to a possible embodiment, a heating layer 19 may include the ultraviolet sensitive material, natural or artificial. This variant makes it possible to add a visual effect to those already obtained, when the spray bottle 1 is placed under ultraviolet rays, natural (sun) or artificial (playful lighting).

In a possible embodiment, the heating layer 19 may be made based on a colorless conductive ink composition, glue or varnish, chosen for example from the conductive adhesive sold under the reference Elecolit® 340 by Eleco. It can be produced by screen printing with a traditional screen printing machine of complex shapes, for example as sold under the reference Dubuit® 329 or Dubuit® 159 by the company Machines Dubuit.

Now more specifically, the production of a thermochromic layer 20 is described.

In one possible embodiment, such a thermochromic layer 20 may be of a material which is colored in the inactivated state and discolored in the activated state. For example, the layer 20 is opaque in the inactivated state and translucent or transparent in the activated state. In another possible embodiment, such a thermochromic layer 20 may be of a material which is discolored in the inactivated state and colored in the activated state. For example, the layer 20 is translucent or transparent in the inactivated state and opaque in the activated state.

According to possible embodiments, a thermochromic layer 20 may cover the entirety of one or both faces 11a, 11b of the outer peripheral wall 5 or it may cover only a portion of one or more faces 11a , 11 b.

To ensure electrical contact at the electrical connection terminals 26, it may be provided that the thermochromic layer 20 does not cover the entire surface of the electrical connection terminals 26 so as to leave free an electrical contact surface. Advantageously, this result can be obtained by temporarily and initially coating the surface of the electrical connection terminals 26 with a protective protective mask-forming protective coating during the production of the thermochromic layer 20, which protective coating can be removed by times the thermochromic layer 20 performed. In one possible embodiment, a thermochromic layer 20 may be made of a heat curing varnish. More generally, such a layer 20 may be made by varnishing.

In one possible embodiment, a thermochromic layer 20 may have an average thickness of less than 100 μm, in particular of between 5 μm and 20 μm, for example of the order of 12 μm.

According to other possible embodiments, a thermochromic layer 20 can incorporate different thermochromic materials or it is formed of several thermochromic sublayers 20a, 20b ... of different compositions, as shown in FIG. Figure 6d. In such cases, and according to the desired aspects for the visual structures 2, the different materials or the different sublayers 20a, 20b ... have different transition temperatures.

The thermochromic layer 20 can be applied by a traditional in-line varnishing machine. The thermochromic varnish may be of the heat-curing type, for example by heating at 60.degree.

25 minutes. For example, it is possible to use a blue opaque thermochromic varnish comprising thermochromic microcapsules such as the thermochromic varnish marketed under the name

Eclipse® by The Alsa Corporation or a blue opaque thermochromic varnish comprising liquid crystals such as the thermochromic varnish marketed under the name Xposure® by The Alsa Corporation. For example, a thermochromic varnish having a temperature range between 5 ° C. and 80 ^° C. is chosen.

According to a development of the invention, the packaging 1 does not comprise electrical means in view of the heating of the heating layer 19 and the visual structure 2 expressive and / or decorative is brought to a temperature above its temperature threshold change of color and / or transparency by an activation command leading to raising the temperature of the heating layer 19, such as that resulting from the temperature rise of the environment in which the package 1 is located: temperature of the hand of the person holding the packaging, temperature of the room where it is located ..

We now describe a method of manufacturing a packaging 1 in the empty state of the type previously described.

Initially, there is a package 1 bare whose inner chamber 6 is empty, power supply means 24, a support means 17 and, if necessary activation control means 25, if those they have a clean structure.

Then, the heating layer or layers 19 and the thermochromic layer or layers 20 are produced, according to the desired arrangement, and as previously described, by rigidly and rigidly fastening them together with immobilization together and at the wall. In this step, for example, the opening 10a is open.

Where appropriate, the support face (s) 18 are previously carried out.

Where appropriate, the thermal confinement layer (s) 30, the intermediate layer (s) 31 or the protective layer (s) 32 are also produced. For this purpose, the layers 19, 20, 30, 31, 32 are made in several passes by techniques in the field of printing or coating. Such techniques are in themselves within the reach of those skilled in the art.

The method optionally comprises a step consisting, from an expressive and / or decorative visual structure 2 of a third desired shape, of determining the shape to be given to the first form with respect to the heating layer 19 and in the second form with respect to the thermochromic layer 20.

The pair or pairs of connection terminals 26 are also made rigidly and rigidly together with immobilization together and at the outer and peripheral wall 5.

The support means 17 provided with the electrical means described above are placed on the outer and peripheral wall 5. Then they are placed in the cavity 16, while the electrical connection terminals 26 and 28 are electrically connected.

Thus, and by way of example, in a first step (FIG. 7a), the two disjoint terminals 26 of an electrical activation circuit are adhesively bonded to the upper part of the outer face 11b of the outer wall and device 5, then,

in a second step (FIG. 7b), at least one heating layer 19 is deposited by forming at its two ends 22 an electrically conductive contact with the two terminals 26 so as to form a conductive circuit on the surface of the outer and peripheral wall 5, then

in a third step (FIG. 7c), a thermochromic layer 20 is deposited covering at least part of the heating layer 19 and not covering the terminals 26, the latter being protected beforehand by a protective coating, then

in a fourth step (FIGS. 7d and 7e), the cover 7 is assembled on the first part 3, and the electrical supply circuit is connected electrically to the terminals 26 making it possible to supply the heating layer 19.

The method of manufacturing a packaging package 1 + certain content C can have two different embodiments.

In a first possible particular embodiment, a package 1 is manufactured in the empty and open state, as described above, then the inner enclosure 6 is filled with the certain content C, then it is mounted on the neck 10 and in the opening 10a the means 15 for sealing and / or dispensing.

In a second possible particular embodiment, there is initially a package 1 bare whose inner chamber 6 is filled with some content C and closed.

Then, one carries out the same operations as before taking care not to undermine the integrity and the qualities of the certain content C.

Of course, this possible embodiment can be envisaged only in the case of a support face assembly 18 / heating layer 19 / thermochromic layer 20 integrated with the outer face 11b of the outer and peripheral wall 5.
