A DEVICE FOR FORMING A FRAGRANCE IMAGE ON AN IMAGE CARRIER
The invention relates to a method for applying a visual image and a fragrance image to a flexible carrier using a printing device provided with one or more ink and fragrance cartridges, each with one or more spray nozzles for ink of different colour and fragrance and control means for these spray nozzles for the purpose of spraying the ink and fragrance according to a determined program.
The invention relates particularly to the controlled application of a fragrance, in particular an associated fragrance, i.e. the image can be discerned not only visually but also via the nasal organ of the reader.
Many techniques are already known to expose the reader to fragrances, whether or not in vaporized form, or by means of fragrance capsules arranged on the image carrier, which can be opened by means of a mechanical process, for instance scratching, whereby the fragrance is released. These are quite expensive techniques which are difficult the user.
A method is known from US-A-5-975-675 wherein use is made of a modified printer with which the visual and fragrance image can be formed.
The invention relates particularly to a method for enabling the emission of a fragrance or composite fragrance of the fragrance image sought after in the visually printed image in simple manner by means of a program drive, in particular by means of computer software . The method according to the invention is distinguished substantially in that at least one ink cartridge with spray nozzle is replaced by a fragrance cartridge with spray nozzle with the same configuration and connecting contacts as the ink cartridge, in order to drive this fragrance cartridge by means of a separate drive programme .
It is possible with the measures proposed by the invention to generate a fragrance image with a standard
printer without essentially changing the configuration of the printer.
In one embodiment these cartridges for the fragrance are embodied with one or more spray nozzles, each of which is connected to the supply chamber for the fragrance .
In the case of a plurality of spray nozzles use can be made of a so-called basic fragrance per spray nozzle, each of which is held in a supply cartridge. When an image is made on the image carrier the basic fragrances can therefore be applied to the image carrier in a predetermined ratio in order to obtain the desired fragrance .
It is also possible according to the invention to use for the purpose of applying the fragrance those of the spray nozzles which are used to apply the printing ink for forming the visual black image on the image carrier.
The means for applying or emitting the fragrance in a device are preferably driven according to the invention by adaptable computer software. The maker of the visual image can hereby form the desired target fragrance with the image via suitable software in very simple manner starting from the available basic fragrances .
Although any pattern of a fragrance image can be applied to the carrier, for instance adjacently of the visual image or in the margin, or in diapositive relative to the visual image, the invention further proposes to also apply the fragrance to the flexible carrier in the same pattern as the visual image. Different images can thus give off their own fragrances on the same carrier, thus making the individual visual images more readily recognizable. The invention finally relates to a cartridge with contacts for driving the spray nozzle (s) which are standard as used in a commercially available printing device. Such a cartridge used for a colour ink to form a visual image can also be used to contain a fragrance. This cartridge can be embodied with a single chamber
suitable only for this fragrance, but can also be provided with a second chamber for the ink.
The above stated device with fragrance and ink- emitting means can generally be driven by computer software, which also opens up the possibility of downloading software via internet, which software can generate and apply respectively a fragrance image and visual image on and to the image carrier.
The invention is further elucidated with reference to the following experiments . In these experiments the following colour/fragrance combinations are used. These are :
Red with Sweet Yellow with Salty Blue with Mountain-fresh
An Inkjet printer is further used of the HP deskjet type 550C with a colour ink cartridge HP51625A, wherein use is made of the different colours in this cartridge. The above mentioned fragrances are mixed into this colour ink and images are applied to copying paper. It has been found that the fragrance is still discernible even a few days after forming of the fragrance image . It has been found that over a period of several days no change in fragrance and colour can be discerned, which indicates that there occurs no degradation of the fragrance or other adverse effect of the fragrance on the ink.
The above experiment shows that the making of a fragrance image according to the invention can take place in very inexpensive manner, wherein use is made only of the existing printing techniques together with existing printing apparatus. The whole system can be readily placed in the market and only requires modification of the cartridges of the known printing devices and, if necessary, writing of new software for the driving .
The invention will be further elucidated with reference to an embodiment, wherein in the drawing:
Fig. 1 shows a perspective arrangement of a usual computer with printer; Fig. 2 shows a schematic arrangement of the ink cartridges suitable for a printer according to figure 1;
Fig. 3A and B are possible configurations of a visual image with fragrance image.
Designated in figure 1 with numeral 1 is a display with computer which is connected via the usual cables to a keyboard 2 and printer 3. This arrangement is assumed to be generally known and is not elucidated further.
It is noted that the computer may be embodied differently, for instance as a laptop, and the printer may take a different form. The printer is an inkjet printer, wherein use is made of a number of cartridges as shown schematically in figure 2. For example, four cartridges 5 can be clicked onto a carrier 6, which carrier can be moved reciprocally along a guide 8 by means of a drive belt 7. In this configuration the left-hand cartridge B is suitable for black ink, while the other cartridges Cl, C2 , C3 are intended for the colours .
According to the invention one of the cartridges, for instance B, can be replaced by a cartridge G provided with a fragrance, this form of cartridge being standard for the printer 3 being used.
Cartridge G can therefore have different configurations subject to the printer being used.
Cartridge G can have either one or a number of chambers, depending on the ink or fragrance (s) held therein.
As is usual, each cartridge is provided with one or more spray nozzles which are separately drivable by the control software stored in the computer. The user of the arrangement of figure 1 is free to generate for instance visual images on the screen, as shown in figures 3A and 3B.
Figure 3A shows a flower I flanked by two image fields G and T, wherein field G indicates this is the field on the printing paper where the fragrance can be deposited; this takes place via cartridge G in figure 2. The field T is then suitable for receiving text . Other configurations are of course possible, and it is noted that the fragrance field is arranged to the side of image I .
Figure 3B shows that three visual images, an apple, a pear, a banana, can in each case be given an individual colour, wherein these images are also covered by the fragrance image. The ink image is generated by cartridges G and Cl-3, wherein cartridge G also applies the fragrance image .
All of these operations can be performed with the control software, wherein it is also possible to reserve an icon in the icon bar D on the screen as fragrance printing instruction, which icon can for instance be displayed in the form of a nose. See the enlarged detail in figure 3B.
The invention is not limited to the above embodiment .
