Description

Conditioning of a transparent liquid

The invention relates to a packaging of a transparent liquid.

In particular, the invention relates to a packaging of the type comprising an at least partly transparent bottle, and a lighting system placed on the bottle so as to emit a light beam in a lighting direction parallel to a central axis from the bottle.

Known packages of this type are used to highlight a bottle filled with a transparent liquid due to a visual effect produced by the propagation of the light beam in the transparent liquid.

However, the known packages do not allow to modulate the visual effect produced.

The invention aims to overcome this problem.

For this purpose, the invention provides a packaging of the aforementioned type further comprising a coating film covering at least a portion of an outer surface of a side wall of the bottle, the coating film comprising at least locally a suitable decoration in order to be backlit by the light beam propagating in the liquid, the decoration comprising a plurality of decorative zones, each decorative zone having an illumination ratio defined by a ratio of a quantity of light measured at a measurement distance from the lighting system through the decor area to a quantity of light measured directly at the measurement distance of the lighting system, the plurality of decorative areas comprising at least a first contrast area and at least a second area of contrast, the first contrast zone having an illumination rate of at least 15%, especially at least 30%, preferably at least 40%, for example at least at 50%, lower than the illumination rate of the second contrast zone.

Thus, the invention provides an interaction between the light beam, the liquid, the decoration of the coating film and possibly the bottle to produce a visual effect. It is then possible to modulate the visual effect by acting on an arrangement of the first and second contrast areas and, where appropriate, on a filling level of the bottle.

In the figures, the same references designate identical or similar elements.

Figures 1 to 3 and 6 illustrate a package 1 according to a first embodiment of the invention.

The package 1 comprises a bottle 2 internally having a volume for receiving a transparent liquid. For the purposes of the present patent application, a transparent liquid is a liquid having an illumination rate greater than 70%, the illumination ratio being defined by a ratio of a quantity of light measured at a distance measuring a light source 16 through a height of liquid on a quantity of light measured directly at the measurement distance of the light source 16. The transparent liquid may in particular be a drink and, in particular, the water, especially spring water, for example flat or gaseous.

The bottle 2 is transparent, in whole or in part, that is to say that it has an illumination rate greater than 70%, the illumination rate then being defined by a ratio of a measured quantity of light at a measurement distance from the light source 16 through the bottle to a quantity of light measured directly at the measurement distance of the light source 16. In the embodiment shown, without being limited thereto, the bottle 2 is disposable and made of plastic material such as PET. Alternatively, the bottle 2 could be made of any other suitable material and in particular glass.

The bottle 2 has a central axis A and has a bottom 3 generally transverse to the central axis A. The bottom 3 has an outer surface on which a bearing surface is formed, and an inner surface defining the volume to receive the liquid. The bottle 2 also has a side wall 4 which extends from the bottom 3 around the central axis A to a neck 5 defining an opening upper 6 opposite the bottom 3. The side wall 4 has an inner surface defining the volume to receive the liquid, and an outer surface opposite to the inner surface. In the embodiment shown, without being limited thereto, the side wall 4 has a succession of three substantially spherical bulges 7, 8, 9: a lower bulge 7 in the vicinity of the bottom 3, an intermediate bulge 8 separated from the lower bulge 7 by a first constriction 10 and an upper bulge 9 in the vicinity of the neck 5 and separated from the intermediate bulge 8 by a second constriction 11. The bulges 7, 8, 9 form transverse wall portions inclined with respect to the central axis A:

between the bottom 3 and a median part of the lower bulge 7,

between the middle part of the lower bulge 7 and the first throttle 10,

between the first constriction 10 and a median part of the intermediate bulge 8,

between the middle part of the intermediate bulge 8 and the second throttle 11,

between the second constriction 11 and a middle portion of the upper bulge

9

- between the middle part of the upper bulge 9 and the neck 5.

A plug 12 may be provided on the neck 5 to reversibly close the top opening 6. In the embodiment shown, the plug 12 may be mounted removably, for example by screwing, on the neck 5. Alternatively , the cap may be permanently mounted on the neck 5 and comprise a movable portion movable between a closed position in which it closes the upper opening 6 and an open position in which it is spaced from the upper opening 6 .

The packaging 1 also comprises a lighting system 15 comprising an electric light source, such as one or more LEDs 16, adapted to emit a light beam, and an autonomous electric power supply device, comprising, for example, a battery and a switch. The battery is connected to the LEDs 16 via the switch to, in an active state, supply the LEDs 16 with electrical energy so as to emit the light beam, and in an inactive state, do not supply the LEDs 16 with electrical energy so as not to emit the light beam. In the embodiment shown, the LEDs 16 and the supply device are mounted on a flat support 17, for example circular having a diameter smaller than the diameter of the bottom 3 of the bottle 2. The LEDs 16 are mounted on the same face of the support 17. The lighting system 15 is placed on the bottle 2 with the face on which the LEDs 16 are mounted against the outer surface of the bottom 3 so as to emit the light beam in a direction of parallel illumination at the central axis A of the bottle 2. The support 17 can be secured to the outer surface of the bottom 3 of the bottle, for example by means of a layer of adhesive material 18.

The package 1 also comprises a coating film 20 covering the outer surface of the side wall 4 of the bottle 2. In the embodiment shown, the coating film 20 has a lower edge 21 located at the bottom 3 of the bottle 2 and an upper edge 22 located at the neck 5 of the bottle 2 so as to cover substantially the entire outer surface of the side wall 4 of the bottle 2. In particular, the bottle 2 initially has an initial filling level where extends a low point of a meniscus formed by a free surface of the liquid. The upper edge 22 of the coating film 20 is then flush with the initial filling level. Alternatively, only a part of the outer surface of the side wall 4 of the bottle 2 could be covered by the coating film 20.

The coating film 20 comprises a decoration having a plurality of decorative zones 25, 26. Each decorative zone 25, 26 has an illumination ratio defined by a ratio of a quantity of light measured at a measurement distance D of the source light 16 through the decorative area on a quantity of light measured directly at the measurement distance of the light source 16. The decoration consists of a particular arrangement of one or more first contrast areas 25 and one or more second In the embodiment shown, the coating film has a plurality of second contrast zones 26 in the form of distributed flames and first contrast areas 25. The first contrast areas 25 have an illumination at least 15%, in particular at least 30%, preferably at least 40%, for example at least 50%, lower than the illumination level of the second contrast zones 26.

In the particular embodiment shown, the first contrast areas are opaque decor areas 25 and the second contrast areas are transparent decor areas 26. The opaque and transparent decor areas 26 have a difference in the level of contrast. illumination of at least 15%, especially at least 30%, preferably at least 40%, for example at least 50%. Alternatively, the first and second contrast areas could be made in any suitable manner to achieve contrast. The first and second contrast zones could be more or less translucent, more or less colored, more or less thick, etc.

By way of non-limiting example, FIGS. 4 and 5 illustrate an experimental device 30 implemented for measuring an illumination rate of various decorative zones. A mask 31 covers the lateral surface 4 'of a generally cylindrical bottle 2' along the central axis A. The mask 31 is essentially opaque with the exception of an opening 32, visible in FIGS. 4 and 5, located at the measurement distance D, for example 2 cm, of the face of the support 17 on which the LEDs are placed. A sensor 33 adapted to measure a quantity of light, for example of the type of Luxmeter MS-200LED operated by the company VOLTCRAFT, is placed opposite the opening 32 and connected to a processing unit.

An initial measurement of the amount of light at the measuring distance D is made directly through the aperture 32. The different decorative areas are then successively placed in the aperture 32 and the amount of light at the measurement distance D. through each of the decorative areas is measured.

The results obtained are shown in the table below.

Board

Thus, a difference in illumination rate of the order of 15%> may correspond to a decoration having black opaque decoration areas and transparent blue or green decorative zones. A difference in illumination rate between 40%> and 50%> can match a decor with blue or green opaque decor areas and white, transparent decor areas.

In Figures 1 and 2, each transparent decor area 26 may be constituted by a window 27 adapted to allow viewing of the side wall 4 from the outside. The window 27 then has an illumination rate greater than 70%. Each window 27 may be obtained by a portion of transparent film. The remainder of the coating film having the opaque decor areas 25 has an illumination rate at least 15% less than that of the transparent decor areas 26. The opaque decor areas 25 can then be black or colored and, by example, blue, red and / or green. As a variant, each window 27 could be formed by a cutout formed in the coating film 20.

In addition, to obtain the desired opacity and, if necessary, vary it, it is possible to vary various parameters of the coating film 20 such as for example: a thickness of the coating film, a thickness or a number of layers printing pattern forming the decoration on the coating film 20, an amount of ink used in the printing layer. In particular, one or more of the opaque decor areas 25 could be a blackout decor area having an illumination rate of less than 10%, preferably less than 5%. The occulting decor area is preferably thin with a thickness less than 10 μιη, preferably less than 5 μιη, especially less than 3 μιη. For example, the blackout decor area includes a layer of metallic ink. The opaque decor area 25 may then be reflective to channel the light to the transparent decor areas 26. Such an effect could be achieved by distributing metal particles on a printing layer. According to other variants, as can be seen from the table above, the transparent decorative zones 26 could be green or blue and the opaque decorative zones 25 could have an illumination rate of at least 15% less than that of the transparent decorative areas 26, that is to say, be black. Or, the transparent decorative areas 26 could be white and the opaque decorative areas 25 could have an illumination rate of at least 40% less than that of the transparent decorative areas 26, that is to say be blue or green.

In Figure 1, the lighting system 15 is off. On the other hand, in FIG. 2, the lighting system 15 is lit so that the light beam emitted by the LEDs 16 supplied with electrical energy by the battery propagates in the liquid in order to backlight the decoration of the coating film 20. the difference in illumination between the first and second contrast zones makes it possible to obtain a particular visual effect which depends on the arrangement of the different contrast areas. In addition, the lower bulge 7, close to the light source 16, has a more intense illumination than the intermediate bulge 8. Due to the propagation of the light beam in the liquid that fills the bottle in Figure 2 and the reflection on the meniscus of the free surface of the liquid, the upper bulge 9 also has a more intense illumination than that of the intermediate bulge 8.

Thus, the light beam, the liquid, the decoration of the coating film 20 and the bottle 2, in particular by their shape, interact to produce a visual effect that can then be modulated by playing on an arrangement of the first and second contrast areas.

As can be seen from FIGS. 6 to 8, the visual effect can also be modulated by varying the level of filling of the bottle 2.

Figure 6 shows, on the left, the packaging 1 described above in the configuration of Figure 2, that is to say with the bottle 2 full up to the initial filling level, and the lighting system 15 alight. On the right, on the other hand, the bottle 2 is empty, the lighting system 15 remaining on. When the bottle is empty, only the lower bulge 7, near the light source 16, has a more intense illumination than the rest of the bottle 2.

The modulation of the visual effect is illustrated in FIGS. 6 and 7 with an experimental device 35 for measuring the illumination as a function of the filling of the bottle 2. A sensor 36, for example of the type of the MS-200LED luxmeter operated by the VOLTCRAFT company, is placed on the neck 5 of the bottle 2, in the upper opening 6, to measure the amount of light from the light beam through different filling levels of the bottle 2. The sensor 36 is connected to a processing unit. The measurements are made with and without coating film. As can be seen from FIG. 8 illustrating the evolution of the illumination as a function of the filling of the bottle 2, the illumination at the sensor 36 increases with the level of filling of the bottle 2. The evolution of the illumination is, moreover, more progressive with a coating film 20 than without coating film.

Figures 9 and 10 show variants of a package 40 according to a second embodiment of the invention. The packaging 40 according to the second embodiment differs from the first embodiment described above only by the decoration of the coating film 41a, 41b. The description will not be repeated in detail and reference is made to the description of the packaging which has already been made for more details.

In Figure 9, the decor includes opaque decoration areas 45a shown a bodywork and transparent decorative areas 46a appearing portholes. At least one of the transparent decor areas 46a has first and second superimposed patterns such that the first pattern masks the second pattern when the decor is not backlit by the light beam and the second pattern becomes apparent when the decor is backlit by the light beam. For example, the first pattern may be a white color filling the window when the lighting system is off and the second pattern may be a visible face in the window when the lighting system is turned on.

As a variant, in FIG. 10, the decoration comprises opaque decoration zones 45b appearing a cabin of an airplane and transparent decorative zones 46b also appearing as portholes. The first pattern may be a white color filling the porthole when the lighting system 15 is off and the second pattern may be a representation of rows of seats inside the aircraft visible in the portholes when the lighting system 15 is on.

To do this, the first and second patterns can be made one on an inner surface of the coating film 41, 42 in contact with the outer surface of the side wall 4 of the bottle 2, and the other on an outer surface coating film 41, 42 opposite to the inner surface.

FIG. 11 shows a packaging 50 according to a third embodiment of the invention which, again, differs from the first embodiment described above only by the decoration of the coating film 51. The description will therefore not be repeated in detail. and reference is made to the description of the packaging which has already been made for more details.

The decor includes opaque decorative areas 55 depicting a car body and transparent decorative areas 56 featuring headlights. The transparent decorative areas 56 can be made by windows 57 obtained by transparent film portions or cuts formed in the coating film 51. The windows 57 are then provided on the transverse wall portion of the upper bulge 9 of the wall 4. The windows 57 and oriented substantially transversely to the light beam can have a more intense illumination than the rest of the bottle 2 when the lighting system 15 is lit. Opaque decoration areas 55 may further be chosen to channel the light beam and concentrate it towards the windows 57.

FIGS. 12 and 13 show variants of the packages 1, 40 of the first and second embodiments shown in FIGS. 1 and 9. In these variants, the battery and the switch of the supply device are replaced by a device of FIG. power supply adapted to generate electrical energy from mechanical energy. In particular, in FIG. 8, the feed device can be activated from a shock on the bottom 3 of the bottle 4. In FIG. 9, the feed device can be activated from a stirring of the bottle 2.

In other embodiments, the activation of the feeder and the illumination of the bottle 2 and the coating film 20, 41a could be controlled in any suitable manner. For example, a control device could be connected to the supply device to switch it between the active state and the inactive state according to a defined sequence defined in particular by a time delay.

In a fourth embodiment illustrated in FIG. 14, the lighting system may be an illuminator 62 of a terminal 60 such as a telephone or the like. The terminal 60 is placed near the bottle 2, for example below, by directing the illumination member 62 towards the volume of the bottle 2, for example through the bottom 3, to illuminate the contents.

In addition to the illumination member 62 adapted to emit a light signal, the terminal 60 may be equipped with an acquisition device 61 adapted to acquire an image and a sound device 63 adapted to emit a sound signal. The terminal 60 may belong to an electronic system illustrated in FIGS. 15 to 17 further comprising a processing unit adapted to recognize, in an image acquired by the acquisition device 61, at least one optical characteristic of the bottle 2 and for associating with the optical characteristic at least one multimedia content.

In the embodiment shown, the optical characteristic may be at least one of the pattern on the coating film 20 and the shape of the bottle 2. Alternatively, the optical characteristic could be any other pattern having areas which differ from one another by one or more optical parameters, visible to a user or at least detectable by an appropriate detection device, such as color, contrast, intensity or illumination rate. The optical characteristic could also be constituted by any other form. The multimedia content includes instructions readable by the processing unit for transmitting a light signal corresponding to the optical characteristic by the illumination member 61. The light signal may comprise one or more lights of different colors and / or intensities. emitted at a preset rate for a light animation. When the terminal 60 is equipped with a sound device 23, the multimedia content may also comprise instructions readable by the processing unit for emitting a sound signal corresponding to the optical characteristic by the sound device 63. may include one or more sounds of different heights and / or intensities, if any, transmitted in synchronization with the light signal.

The terminal 60 comprises a housing 64 portable by hand by a user and enclosing a set of electronic components. In particular, in FIGS. 15 and 16, the terminal 60 is a telephone comprising on a front face a display screen 65, possibly a touch screen, a microphone 66, a loudspeaker 67 and one or more control keys 68. a rear face, the terminal 60 includes an objective of the acquisition device 61, a flash lamp 69 adapted for image acquisition by the acquisition device in low light conditions and another speaker 70. The display screen 65 and flash lamp 69 can serve as illumination member 62, the first to emit a light signal in the form of a more or less diffuse light surface and the second to emit a light signal in the form a light beam more or less focused in an illumination direction. The speakers 67, 70 of the front and rear faces can serve as a sound device 63.

In FIG. 17, the processing unit comprises a remote server 71 in which is stored a database storing a plurality of optical characteristics of bottles and a plurality of multimedia contents each associated with an optical characteristic. The processing unit also comprises a processor 72 and a communication interface 73 mounted in the housing 64 of the terminal 60. The communication interface 73 is adapted to communicate, preferably remotely, according to any appropriate protocol but possibly via a wire link. , with remote networks and, in particular, with the server 71. The processor 72 is connected to the acquisition device 61, to the illumination members 62, namely the display screen 65 and the flash lamp 69, to the sound devices 63, namely the speakers 67, 70 of the front and rear faces, the microphone 66, the control keys 68 and the communication interface 73. The processor 72 is adapted to recognize, in the image acquired by the acquisition device 61, the optical characteristic of the bottle 1 and to associate with this optical feature at least one of the multimedia contents obtained from the database stored on the server 71 by the communication interface 73.

Alternatively, the processing unit can be fully contained in the terminal 60. In addition to the processor 72, the processing unit then comprises a memory in which the database is stored.
