Description

Title of the invention: Set of color-correcting devices and corresponding manufacturing method

[0001] The invention relates to the field of correction devices allowing the application of a correction composition to a sheet in particular to correct an error.

[0002] More specifically, in certain examination centers, such as those for the competitive entrance exam for medical studies (PACES) or for reception staff exams for Regional Centers for University and School Services (CROUS), it has been proposed to distribute colored paper to candidates to ensure the smooth running of the exam. Candidates sitting next to each other do not receive the same color exam paper to prevent any exchanges. To this end, the colored paper is distributed randomly, so that the candidate does not know which color paper they will receive. French examination centers generally offer blue, pink, green, and yellow paper.

[0003] In this type of circumstance, the occurrence of an error requiring correction has not yet been fully resolved. Indeed, due to the often significant stakes, exams are written in ink that cannot be erased with an eraser, which means that in the event of an error requiring correction, a correction device must be applied to the section to be corrected, then the correction compound must be allowed to dry, and then the writing must be done on the dried text.

[0004] Unfortunately, the correction devices proposed in the prior art are in white tones, which causes examination color sheets to be stained with white marks in various places of the type visible in [Fig.1].

[0005] This greatly impairs the legibility of the copy. Furthermore, it causes discomfort and premature fatigue for the person correcting the copy due to these color differences, which force significant eye strain.

[0006] Colored paper is also used in some primary school classes, generally in grades 4 and 5; this includes French, history, geography, or art classes. Furthermore, some communication notebooks may contain colored paper. In addition, some hospitals use yellow or light green colored paper. Moreover, index cards and binders used by professionals such as accountants are also colored. All these applications require appropriate color correction materials.

[0007] Furthermore, color-coded cards are known to be easier to remember. In the event of correction, this advantage becomes a disadvantage if a white correction fluid is used. of the prior art is used because it similarly causes discomfort and premature fatigue for the user.

[0008] A first objective of the invention is to propose a solution to limit the discomfort and premature fatigue of people correcting color exam papers.

[0009] A second objective is to enable the candidate to adapt to the random distribution of color copy.

[0010] To achieve these objectives, the invention proposes a set of corrector devices for different colored sheets in tones other than white tones, in which the corrector devices comprise a corrector composition, characterized in that the corrector compositions comprise color pigments such that the corrector composition of each corrector device corresponds to each of said colored sheets.

[0011] Advantageously, having several color correction devices corresponding to the colored sheets allows the candidate to choose the appropriate color and use it during the exam. The candidate can therefore adapt to the random distribution of colored copies.

[0012] In addition, by using the correction device corresponding to the color of the copy, a uniform color is obtained so as to limit the inconvenience and premature fatigue of people correcting color exam copies.

[0013] According to other aspects taken individually or combined according to all technically feasible combinations: - the corrective devices are at least blue, pink, green and yellow; and / or -at least one correction device includes several compartments, one for each color; and / or - The color composition includes a mixture of white color corrector composition and acrylic paint of the intended color.

[0014] The invention further relates to a corrector device for colored paper in tones other than white tones, in which the corrector device comprises a corrector composition, characterized in that the corrector composition comprises at least one color pigment so that the corrector composition of the corrector device corresponds to said colored paper.

[0015] The invention also relates to a method for manufacturing at least one corrective composition for a set of corrective devices according to the invention, the method comprising a step for mixing a white color corrective composition and an acrylic paint of each color envisaged, so as to obtain said corrective composition.

[0016] The invention will be further detailed by describing non-limiting embodiments, and based on the accompanying figures, among which: - [Fig.l] illustrates a plan view of a sheet of blue colour on which a corrector is applied according to the prior art; - [Fig.2] illustrates a plan view of a blue colored sheet on which a blue color corrector of an assembly according to the invention is applied; - [Fig. 3] illustrates a plan view of a set of corrective devices according to a first embodiment; and - [Fig.4] illustrates a plan view of a set of corrective devices according to a second embodiment.

[0017] The invention relates to an assembly (or kit) of CB, CR, CV, CJ correction devices. The invention is particularly suitable for application to various colored sheets (FB) in shades other than white, such as the sheets generally distributed to candidates during examinations.

[0018] In France, for examinations, colored paper is generally blue (FB), pink, green, and yellow. The application of the invention relates to writing materials designated by these colors or derivatives for sheets, folders, index cards, or binders, under the Pollen™, Clairefontaine™, Exacompta™, or other stationery brands. Of course, other colors can be considered depending on the application of the invention.

[0019] For the remainder of the description, we will assume that a blue FB sheet is used as a copy and is shown in Figures 1 and 2 for the description. Any other color (other than those in shades of white) could be used in the same way.

[0020] Each of the CB, CR, CV, CJ corrector devices comprises a specific corrector composition. The user may have a set of two, three, four (or more) CB, CR, CV, CJ corrector devices.

[0021] According to the invention, each corrector composition comprises at least one color pigment such that the corrector composition corresponds to a specific FB color sheet. The color is adjusted to match the tone of each of the commonly used color sheets.

[0022] Advantageously, having several color correction devices CB, CR, CV, CJ corresponding to the sheets allows the appropriate color (CB) to be selected and used during the exam. Thus, in the illustrated example, the candidate only needs to use the blue CB correction device to match the blue FB sheet.

[0023] The candidate therefore adapts to the random distribution of copies in the examination center.

[0024] Furthermore, by using the CB correction device corresponding to the color of the FB copy, a uniform color is obtained on the corrected FB copy, as can be seen. This can be seen by comparing figures 1 and 2. Thus, the user significantly limits the discomfort and premature fatigue of people correcting color exam papers.

[0025] The colour corrector composition can be liquid or paste.

[0026] In particular, the color composition comprises a mixture of white color corrector and an acrylic paint of the desired color. Advantageously, this allows for rapid manufacturing and a formulation with very good miscibility and a short drying time. Commercially available acrylic paints can be used directly without complex formulation by a chemist.

[0027] Preferably, the correction devices are at least blue (CB), pink (CR), green (CV), and yellow (CJ). This allows them to be adapted to French examination papers. Of course, other colors can be considered depending on the application or the usual choices of other examination centers.

[0028] The correction device assembly can be envisaged to comprise four (or more) separate devices, as illustrated in [Fig. 3]. According to one embodiment, at least one correction device comprises several compartments, one for each color. This can be illustrated by [Fig. 4]. This saves space by using several compartments in the same device. A device with more than two compartments is conceivable, for example, four or five compartments. The compartments can have opposite orientations, as in [Fig. 4], or be oriented in the same direction and sense (not shown), or even be arranged in a star pattern (not shown).

[0029] The invention also relates to a method for manufacturing one or more CB, CR, CV, CJ correction devices as described above, adapted for said different FB colour sheets.

[0030] Preferably, the process is based on a white color corrector composition. This type of composition can have color variations in white tones in the prior art. The invention proposes starting with such a composition and mixing it with acrylic paint to obtain a colored corrector composition.

[0031] The applicant tested various paints and pigments, encountering many miscibility problems with the white correction fluid composition. Surprisingly, the applicant found that mixing them with acrylic paint easily resulted in good miscibility and an intense color.

[0032] In the preferred variant, half a volume of acrylic paint can be mixed with half a volume of white corrector.

[0033] In addition, acrylic paints allow for a particularly rapid drying of the color corrector composition so that the user can quickly rewrite the corrected text.

[0034] Advantageously, the invention makes it possible not to search for as many formulations as there are colours, but to have a homogeneous mixture by mixing acrylic paint.

[0035] A production line may for example have a white corrector section, then part of the white corrector obtained passes into other sections where an acrylic paint of the different colors is integrated and mixed.

[0036] Thus, intense colour correctors can easily be obtained for use on coloured media such as sheets, folders, binders or other media.
