Abstract

PRINCIPE ET METHODES DE FABRICATION DE PRESERVATIFS OFFRANT UNE PERCEPTION TACTILE SUPERIEURE A LA PERCEPTION NATURELLE La présente invention propose la fabrication de nouveaux types de préservatifs (1) possédant des reliefs (2) dont les dimensions sont situées au niveau des seuils de discrimination tactile (hauteur, largeur et espacement), seuils qui sont d’ordre millimétrique et submillimétrique. Les techniques antérieures permettent de fabriquer notamment des préservatifs lisses très minces ou des préservatifs texturés (perlés et/ou nervurés par gaufrage), mais les motifs texturaux ainsi réalisés sont de l’ordre de quelques dixièmes de millimètre car dimensionnellement proches de l’épaisseur et ne permettent donc pas d’atteindre les seuils de discrimination tactile. Ainsi, les techniques antérieures offrent moins de sensation tactile que l’absence de préservatif (conditions naturelles) d’où un manque d'appétence et parfois un rejet des utilisateurs. La présente invention permet la fabrication de préservatifs offrant des sensations tactiles supérieures aux conditions naturelles, ce qui devrait favoriser leur utilisation. L’invention revendique l’utilisation d’une théorie scientifique pour une application pratique selon les Directives INPI (exclusions L611-10 CPI - Directives d’examen de l’INPI, I-C-VII 1.1). De manière scientifique, à l’instar de la signalétique Braille, on observe en effet que les seuils de discrimination tactile (en hauteur, largeur et espacement) au niveau des organes génitaux sont caractérisés en ce qu’ils sont d’ordre millimétrique et submillimétrique. L’invention décrit cinq modes de fabrication de préservatifs possédant des reliefs de taille millimétrique et submillimétrique selon le principe de perception des seuils de discrimination tactile.

The prior techniques make it possible in particular to manufacture very thin smooth condoms or textured condoms (beaded and/or ribbed by embossing), but the textural patterns thus produced are of the order of a few tenths of a millimeter because dimensionally close to the thickness and therefore do not make it possible to reach the tactile discrimination thresholds. Thus, the previous techniques offer less tactile sensation than the absence of a condom (natural conditions) resulting in a lack of appetite and sometimes rejection by users. The present invention allows the manufacture of condoms offering tactile sensations superior to natural conditions, which should promote their use. The invention claims the use of a scientific theory for a practical application according to the INPI Directives (exclusions L611-10 CPI - INPI Examination Guidelines, I-C-VII 1.1). In a scientific way, following the example of Braille signage, we indeed observe that the thresholds of tactile discrimination (in height, width and spacing) at the level of the genital organs are characterized in that they are of a millimetric and sub-millimetric order. . The invention describes five modes of manufacturing condoms having reliefs of millimeter and sub-millimeter size according to the principle of perception of tactile discrimination thresholds.

Description

PRINCIPLE AND METHODS OF MANUFACTURING CONDOMS OFFERING TACTILE PERCEPTION SUPERIOR TO NATURAL PERCEPTION

L’invention concerne la fabrication de nouveaux types de préservatifs offrant des sensations tactiles voisines ou supérieures aux conditions naturelles (absence de préservatif).
Nous prenons ici l’expression « perception tactile » selon le sens général, à savoir la perception de sensations par le toucher transmise par l'intermédiaire de la peau, des muqueuses, etc.
La présente invention décrit plusieurs procédés de fabrication qui modifient ou transforment des modes de réalisations existants et permettent de fabriquer de nouveaux types de préservatifs (1) avec des éléments topographiques (2) de taille millimétrique et submillimétrique procurant des sensations tactiles voisines des conditions naturelles (voir ).The invention relates to the manufacture of new types of condoms offering tactile sensations close to or superior to natural conditions (absence of a condom).
We take here the expression "tactile perception" according to the general meaning, namely the perception of sensations by touch transmitted through the intermediary of the skin, mucous membranes, etc.
The present invention describes several manufacturing processes which modify or transform existing embodiments and make it possible to manufacture new types of condoms (1) with topographic elements (2) of millimetric and sub-millimetric size providing tactile sensations close to natural conditions ( to see ).

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Le préservatif est un étui mince et souple, imperméable au sang ainsi qu'aux sécrétions. Il en existe deux types : le préservatif masculin et le préservatif féminin, d'introduction plus récente. Il est généralement fabriqué en Latex naturel ou parfois en Polyuréthane ou Polyisoprène comme décrit ci-dessous [Ref.1].
Nous utilisons ici la définition générale du mot latex, à savoir une émulsion aqueuse de certains polymères naturels (Latex naturel) ou synthétiques, émulsion issue d'une polymérisation [Ref.2].
Les préservatifs ont deux fonctions primordiales : (i) une fonction de contraceptif : la contraception est l’une des solutions les plus connues au problème de surpopulation car elle permet de limiter le nombre des naissances et représente la solution la plus facile à déployer et la moins onéreuse. (ii) une fonction de prévention des infections sexuellement transmissibles : notons que le préservatif est le seul contraceptif qui protège également des infections sexuellement transmissibles.
En ce qui concerne les modèles masculins, il existe des préservatifs avec une forme lisse qui revendiquent une sensation améliorée lorsque le préservatif est très mince et des préservatifs dits 'perlés’ et/ou ‘nervurés' qui comportent des formes en relief positif ou négatif (rainures et/ou granulosités), mais là encore ces modèles offrent moins de sensation tactile que l’absence de préservatif (conditions naturelles).The condom is a thin and flexible case, impermeable to blood as well as secretions. There are two types: the male condom and the more recently introduced female condom. It is generally made of natural Latex or sometimes of Polyurethane or Polyisoprene as described below [ Ref.1 ].
We use here the general definition of the word latex, namely an aqueous emulsion of certain natural polymers (natural Latex) or synthetic, emulsion resulting from a polymerization [ Ref.2 ].
Condoms have two primary functions: (i) a contraceptive function: contraception is one of the most well-known solutions to the problem of overpopulation because it makes it possible to limit the number of births and represents the easiest solution to deploy and the less expensive. (ii) a function of preventing sexually transmitted infections: note that the condom is the only contraceptive that also protects against sexually transmitted infections.
As for the male models, there are condoms with a smooth shape which claim an improved feel when the condom is very thin and so-called 'beaded' and/or 'ribbed' condoms which feature positive or negative raised shapes ( grooves and/or graininess), but again these models offer less tactile sensation than the absence of a condom (natural conditions).

Dimensions courantes des préservatifsCommon condom sizes

Les dimensions des préservatifs masculins actuels sont variables : des longueurs variant de 165 à 220 mm, des largeurs nominales variant de 41 à 69 mm (correspondant à des diamètres nominaux de 26 à 44 mm) et des épaisseurs variant de 40 à 110 microns (soit de 0.4 à 1.1 dixièmes de millimètre).
Méthode de fabrication la plus courante The dimensions of current male condoms are variable: lengths varying from 165 to 220 mm, nominal widths varying from 41 to 69 mm (corresponding to nominal diameters of 26 to 44 mm) and thicknesses varying from 40 to 110 microns (i.e. from 0.4 to 1.1 tenths of a millimeter).
Most common manufacturing method

La méthode de fabrication la plus courante est celle du moulage par trempage [Ref.3].The most common manufacturing method is that of dip molding [ Ref.3 ].

Selon cette méthode, des moules phalliques sont immergés lentement dans un Latex, à savoir une émulsion aqueuse de certains polymères naturels (Latex naturel) ou synthétiques [Ref.2] (Latex de Polyisoprène, Polyuréthane, Copolymères Butadiène-Acrylonitrile, etc.).
Le trempage forme une couche presque invisible sur leur paroi. Le film subit une première phase de séchage dans un environnement filtré afin d’éviter toute contamination atmosphérique. Une fois sec, le moule enduit est à nouveau trempé et séché afin de renforcer la solidité du film de latex avec cette deuxième couche.
Il s’ensuit alors généralement, pour les matériaux caoutchoutiques, une étape de vulcanisation qui a pour but d’améliorer l’élasticité et la résistance du latex en lui apportant du soufre. Le préservatif, toujours placé sur son moule, est passé au four à une température de 50 à 120 °C. Après la vulcanisation, vient l’étape du rinçage qui permet d’éliminer la majorité des allergènes accumulés durant le procédé de fabrication. Finalement, à l’aide de jets à haute pression, le préservatif est détaché de son moule avant d’être séché puis roulé sur lui-même.
L’une des revendications principales des techniques antérieures de fabrication de préservatifs est la fabrication de préservatifs minces à très minces (1.1 à 0.4 dixièmes de millimètre, soit 110 à 40 microns) offrant de meilleures sensations que les préservatifs épais.
Notons que cette technique de fabrication permet de mettre au point des préservatifs texturés, élaborés à partir de moules perlés, rainurés ou encore nervurés. Notons cependant que les motifs texturaux ainsi réalisés sont de l’ordre de quelques dixièmes de millimètre car ils sont dimensionnellement proches de l’épaisseur.According to this method, phallic molds are slowly immersed in a Latex, namely an aqueous emulsion of certain natural polymers (Natural Latex) or synthetic [ Ref.2 ] (Latex of Polyisoprene, Polyurethane, Butadiene-Acrylonitrile Copolymers, etc.).
The soaking forms an almost invisible layer on their wall. The film undergoes a first phase of drying in a filtered environment in order to avoid any atmospheric contamination. Once dry, the coated mold is again soaked and dried in order to reinforce the solidity of the latex film with this second layer.
It then generally follows, for rubber materials, a vulcanization step which aims to improve the elasticity and resistance of the latex by providing it with sulfur. The condom, still placed on its mould, is baked at a temperature of 50 to 120°C. After vulcanization, comes the rinsing stage which eliminates the majority of allergens accumulated during the manufacturing process. Finally, using high pressure jets, the condom is detached from its mold before being dried and then rolled on itself.
One of the main claims of previous condom manufacturing techniques is the manufacture of thin to very thin condoms (1.1 to 0.4 tenths of a millimeter, or 110 to 40 microns) offering better sensations than thick condoms.
It should be noted that this manufacturing technique makes it possible to develop textured condoms, made from beaded, grooved or even ribbed moulds. Note however that the textural patterns thus produced are of the order of a few tenths of a millimeter because they are dimensionally close to the thickness.

PROBLEME TECHNIQUETECHNICAL PROBLEM

Aujourd’hui, l’usage des préservatifs est limité, entre autres, par le manque d'appétence des utilisateurs envers les préservatifs fabriqués selon les techniques antérieures, un certain nombre d’entre eux rejetant cette solution au motif qu'elle ne procure pas les mêmes sensations que les conditions naturelles (absence de préservatif).
Pour pallier ce problème, certains préservatifs dits perlés, rainurés ou nervurés comportent des formes en relief positif ou négatif (rainures et/ou granulosités), mais là encore la solution ne satisfait pas l'attente de tous les utilisateurs.
Selon une observation de ce brevet, nous constatons que la structure et la taille des reliefs réalisables avec les techniques antérieures, ne permettent pas d’atteindre un seuil de discrimination tactile satisfaisant.Today, the use of condoms is limited, among other things, by the lack of appetite of users for condoms manufactured according to previous techniques, a certain number of them rejecting this solution on the grounds that it does not provide the same sensations as natural conditions (absence of a condom).
To overcome this problem, certain so-called beaded, grooved or ribbed condoms have shapes in positive or negative relief (grooves and/or graininess), but here again the solution does not meet the expectations of all users.
According to an observation of this patent, we note that the structure and the size of the reliefs which can be produced with the prior techniques do not make it possible to reach a satisfactory tactile discrimination threshold.

Méthodes de fabrication récentes, brevetées ou en cours de dépôt de brevet mais non lancées en fabrication à ce jourRecent manufacturing methods, patented or patent pending but not launched in production to date

A ce jour, un certain nombre de brevets ont été déposés sur des concepts qui n’ont généralement pas encore conduit à une mise sur le marché.
Nous avons effectué une analyse des brevets les plus pertinents dans le sens où ces brevets pourraient prétendre offrir des sensations tactiles supérieures aux préservatifs actuellement commercialisés (voir REFERENCES).
Ils portent les références bibliographiques 11 à 18. Les concepts décrits dans les références 11 à 16 n’ont pas de rapport avec notre invention : particules de poly-isoprène réticulées afin d’augmenter la résistance du préservatif [Ref.11], embout en mousse pour distribuer une substance antivirale [Ref.15], préservatif en polyuréthane plus solide [Ref.16]. Les concepts décrits dans les références 12, 13 et 14 ont une revendication de plaisir amélioré : libération de liquide [Ref.12], préservatif intérieur et préservatif extérieur avec un anneau élastomérique entre les deux [Ref.13], anneau mobile permettant de bloquer une partie de l’épiderme [Ref.14], mais n’ont pas non plus de rapport avec notre invention car ils ne revendiquent pas la possibilité de sensations tactiles supérieures aux conditions naturelles. Enfin, les références 17 et 18, qui peuvent sembler pertinentes, n’ont cependant pas de revendication à améliorer les sensations au-delà des conditions naturelles : bossage annulaire pour éviter la contamination [Ref.17], premier segment et un deuxième segment de diamètre plus faible et structuré [Ref.18].To date, a certain number of patents have been filed on concepts which have generally not yet led to a placing on the market.
We have carried out an analysis of the most relevant patents in the sense that these patents could claim to offer superior tactile sensations to the condoms currently marketed (see REFERENCES).
They bear the bibliographical references 11 to 18. The concepts described in references 11 to 16 have no connection with our invention: cross-linked poly-isoprene particles to increase the resistance of the condom [ Ref.11 ], tip in foam to dispense an antiviral substance [ Ref.15 ], stronger polyurethane condom [ Ref.16 ]. The concepts described in references 12, 13 and 14 have a claim of improved pleasure: release of liquid [ Ref.12 ], interior condom and exterior condom with an elastomeric ring between the two [ Ref.13 ], mobile ring allowing to block part of the epidermis [ Ref.14 ], but neither have any relation with our invention because they do not claim the possibility of tactile sensations superior to natural conditions. Finally, references 17 and 18, which may seem relevant, however do not claim to improve sensations beyond natural conditions: annular boss to avoid contamination [ Ref.17 ], first segment and a second segment of smaller diameter and structured [ Ref.18 ].

Limitation des techniques de fabrication antérieuresLimitation of Prior Manufacturing Techniques

Les reliefs réalisables avec les techniques antérieures ne permettent pas d’atteindre un seuil de discrimination tactile satisfaisant pour les raisons suivantes :
La réalisation de ces reliefs ou formes topographiques se faisant généralement par déformation de la paroi desdits préservatifs (techniques de gaufrage, de moulage, etc.), la variation topographique est de l’ordre de l’épaisseur de la paroi, généralement de quelques dixièmes de millimètre, et donc inférieure au seuil de discrimination tactile dimensionnel.
En fait, ces techniques ne permettent pas la fabrication de motifs plus grands car les limitations topographiques sont de deux ordres : (i) la paroi étant très élastique, des déformations trop grandes seraient amorties par l’élasticité de l’ensemble. (ii) un gaufrage (voir [Ref.4])trop important compromettrait la solidité du préservatif.
Sachant que les seuils de discrimination tactile dimensionnels au niveau des organes génitaux sont caractérisés en ce qu’ils sont d’ordre millimétrique en hauteur et d’ordre submillimétrique en largeur et espacement, on comprend que la solution soit peu efficace.The reliefs achievable with the previous techniques do not make it possible to reach a satisfactory tactile discrimination threshold for the following reasons:
The realization of these reliefs or topographic shapes generally being done by deformation of the wall of said condoms (techniques of embossing, molding, etc.), the topographic variation is of the order of the thickness of the wall, generally of a few tenths millimeter, and therefore lower than the dimensional tactile discrimination threshold.
In fact, these techniques do not allow the fabrication of larger patterns because the topographical limitations are of two kinds: (i) the wall being very elastic, excessive deformations would be damped by the elasticity of the assembly. (ii) embossing (see [Ref.4])too large would compromise the strength of the condom.
Knowing that the dimensional tactile discrimination thresholds at the level of the genital organs are characterized in that they are of the order of millimeters in height and of the order of sub-millimeters in width and spacing, it is understood that the solution is not very effective.

Le principe de la perception tactileThe principle of tactile perception

Nous prenons ici l’expression « perception tactile » selon le sens général, à savoir la perception de sensations par le toucher transmise par l'intermédiaire de la peau et des muqueuses.
La perception tactile est l’une des sensations détectées par des récepteurs sensoriels situés sous l’épiderme, les récepteurs somesthésiques [Ref.3].
La peau possède plusieurs types de récepteurs sensoriels, qui réagissent en fonction de stimuli différents, et qui envoient des informations interprétables par le cerveau, comme les corpuscules de Merkel et plus particulièrement les corpuscules de Meissner qui sont des mécanorécepteurs (pression légère, toucher discriminant, vibration de basse fréquence), localisés dans la peau glabre (lèvres, mamelons, organes génitaux externes, bout des doigts).
Selon la littérature, il est à noter que la grandeur du champ récepteur, à savoir le seuil de discrimination tactile dimensionnel, est le plus souvent supérieur au millimètre [Ref.5] à [Ref.8].
Par exemple, la perception tactile des doigts est utilisée dans la signalétique Braille, système d’écriture tactile à points saillants à l’usage des personnes aveugles ou fortement malvoyantes.
Ainsi, dans la signalétique Braille, les motifs saillants ont des dimensions topographiques de 0.5 à 1 mm en hauteur, de 1.2 à 1.5 mm en largeur et de 2.3 à 2.5 mm en espacement.
Notons que des motifs acérés seraient techniquement perceptibles mais ils seraient douloureux et non viables. C’est pourquoi la discrimination ne peut se faire que sur la perception dimensionnelle de motifs saillants (reliefs) et de leur espacement.
A l’instar de ce qui existe dans la signalétique Braille, il y a une perception somesthésique similaire au niveau des organes génitaux. Cependant, en raison d’une moindre sensibilité, les seuils de discrimination tactile au niveau des organes génitaux sont dimensionnellement plus grands qu’au niveau des doigts, à savoir d’ordre millimétrique en hauteur et de l’ordre de plusieurs millimètres en espacement.
Ceci explique pourquoi les techniques antérieures, dont la taille des reliefs réalisables est généralement de l’ordre de quelques dixièmes de millimètre, ne permettent pas d’atteindre un seuil de discrimination tactile satisfaisant.We take here the expression "tactile perception" according to the general sense, namely the perception of sensations by touch transmitted through the skin and mucous membranes.
Tactile perception is one of the sensations detected by sensory receptors located under the epidermis, the somatosensory receptors [ Ref.3 ].
The skin has several types of sensory receptors, which react according to different stimuli, and which send information that can be interpreted by the brain, such as Merkel's corpuscles and more particularly Meissner's corpuscles which are mechanoreceptors (light pressure, discriminating touch, low-frequency vibration), localized in the glabrous skin (lips, nipples, external genitalia, fingertips).
According to the literature, it should be noted that the magnitude of the receptive field, namely the dimensional tactile discrimination threshold, is most often greater than one millimeter [ Ref.5 ] to [ Ref.8 ].
For example, the tactile perception of fingers is used in Braille signage, a tactile writing system with salient points for use by blind or severely visually impaired people.
Thus, in Braille signage, the salient patterns have topographic dimensions of 0.5 to 1 mm in height, 1.2 to 1.5 mm in width and 2.3 to 2.5 mm in spacing.
Note that sharp patterns would be technically noticeable but they would be painful and unsustainable. This is why discrimination can only be made on the dimensional perception of salient patterns (reliefs) and their spacing.
Like what exists in Braille signage, there is a similar somatosensory perception at the level of the genitals. However, due to less sensitivity, the tactile discrimination thresholds at the level of the genital organs are dimensionally larger than at the level of the fingers, namely of the order of millimeters in height and of the order of several millimeters in spacing.
This explains why the prior techniques, the size of the reliefs that can be produced is generally of the order of a few tenths of a millimeter, do not make it possible to reach a satisfactory tactile discrimination threshold.

Five embodiments of the invention are proposed which modify or transform existing embodiments.

Application de l’invention à différents modes de fabricationApplication of the invention to different manufacturing methods

La présente invention n'est nullement limitée aux modes de réalisation décrits ci-dessous et l'homme du métier saura y apporter toute variante conforme à son esprit.The present invention is in no way limited to the embodiments described below and those skilled in the art will know how to add any variant to it in accordance with their spirit.

F.I.M. (Manufacture Insertion Moulding) - Application to a method of Manufacturing according to a technique of Insertion of topographic elements between two coating layers of the Dip Molding method ([Fig. 2.a] to [Fig. 4])

Selon l’un des modes de réalisation de l’invention, le préservatif est réalisé à l’aide de la technique de fabrication de moulage par trempage [Ref.3]citée plus haut. La présente invention se rapporte ainsi, selon le mode ‘F.I.M.’, à un procédé de fabrication de moulage par trempage avec les différences spécifiques principales suivantes :According to one embodiment of the invention, the condom is made using the dip molding manufacturing technique [Ref.3]cited above. The present invention thus relates, according to the mode ‘FIM’, to a dip molding manufacturing process with the following main specific differences:

The phallic mold (3) used in the standard mode is a standard smooth cylinder as described [Fig. 2.a] and [Fig. 2.b].
according to a second mode and according to claim8 of this patent, the manufacturing mold (4) is possibly widened in the zones where the topographical patterns will be inserted to counterbalance the increase in local elastic resistance induced by the thickness and the rigidity of the aforementioned patterns. Knowing that the diameter of condoms is generally adjusted to approximately 85% of the diameter of the penis [Ref.9], it can be estimated that the crown of the mold (4) necessary for resistance compensation is of the order of 1 to 2.5 mm depending on the size.
during a first step of coating a layer (5) as described [Fig. 3.a], we stop at the latex deposition phase before the drying phase.
a second step, which is the subject of the claim2of this patent, consists in placing topographic elements (6) on the non-dry layer as described [Fig. 3.b] and [Fig. 3.c] using the dispensing device (7) described in [Fig. 4]. As the layer is not yet dry, the topographic elements adhere to the film.
according to an advantageous and non-limiting characteristic, the dispensing device (7) holds the elements thanks to a suction system under restricted vacuum, the vacuum being cut off when the elements adhere to the film.
according to an advantageous and non-limiting characteristic, topographic elements are placed all around the cylinder using several distribution devices (7) as described [Fig. 4] (schematic views).
after deposition/bonding of the devices, the drying and cross-linking phase can be carried out.
according to an advantageous and non-limiting characteristic, the third step consists in depositing one or more coating layers (8), as described [Fig. 3.d]. This step allows the encapsulation of topographic elements.
after encapsulation deposition, final drying and vulcanization phases are carried out before the final demolding step, which is carried out using high-pressure jets as in the conventional molding process.

Plus précisément, le procédé selon le mode ‘F.I.M.’ :More specifically, the process according to the ' FIM ' mode:

according to main claim 1 of this patent, the ' FIM ' embodiment allows the manufacture of condoms having reliefs of size close to or greater than the tactile discrimination thresholds (in height, width and spacing).
more specifically, the salient patterns preferably have topographic dimensions of the order of millimeters in height and of the order of submillimeters in length and width, as well as in spacing (see [Fig. 1] and [Fig. 3.d]).
according to an advantageous and non-limiting characteristic, the first coating step (5) can consist of two successive layers, one then stops before the drying phase of the second layer.
according to an advantageous and non-limiting characteristic, the topographic elements (6) are preferably of elastomeric nature and/or have a high elongation capacity.
according to an advantageous and non-limiting characteristic, the topographic elements (6) can be of cylindrical shape, the diameter of the aforesaid elements being of sub-millimeter order.
according to an advantageous and non-limiting characteristic, the topographical elements (6) can be rectangular in shape, of sub-millimeter length and width and have rounded and/or chamfered edges.
according to another claim 3 of this patent, the material of the topographic elements (6) can be of the latex foam type.
according to an advantageous characteristic arising from their porosity, the aforementioned topographic elements in latex foam have a greater elongation capacity than the latex of the encapsulation films, which makes it possible to avoid any delamination.

F.E.M. (Fabrication of Elements by Molding) - Application to a mode of Manufacture of salient topographic elements according to the manufacturing technique of Molding by dipping ([Fig. 5.a] and [Fig. 5.b])

Selon l’un des modes de réalisation de l’invention, le préservatif est réalisé à l’aide de la technique de fabrication de moulage par trempage [Ref.1]citée plus haut. La présente invention se rapporte ainsi, selon le mode ‘F.E.M.’, à un procédé de fabrication de moulage par trempage avec les différences spécifiques principales suivantes :According to one embodiment of the invention, the condom is made using the dip molding manufacturing technique [Ref.1]cited above. The present invention thus relates, according to the mode ‘WEF’, to a dip molding manufacturing process with the following main specific differences:

the mold is not a smooth cylinder as in conventional processes. The mold (9) according to the ' FEM ' mode has holes whose shape allows them to be unmolded. Preferably, the holes are conical or cylindrical, but they can be oblong, blocky, pyramidal, as described in [FIG. 5.a] (for example: Conical patterns in perpendicular arrangement (10) - Cylindrical patterns in angular arrangement (11) - Pyramidal, polyhedral patterns (12) - Cylindrical patterns (13)).
according to an advantageous and non-limiting characteristic and according to another claim 10 of this patent, the aforesaid grooves (11) are dug with an angle of inclination, as described [Fig. 5.a].
the holes (10) to (13) allow the manufacture of salient topographic elements of a size and an arrangement such that these elements make it possible to reach the tactile discrimination thresholds.
the number of soaks is preferably greater than that of prior techniques.
according to an advantageous characteristic detailed below, several different types of latex can be used for filling the holes.
according to a claim of this patent detailed below, after production of a first layer of latex, the latex used for optimal filling of the holes is a latex of the latex foam type.
in a final phase, the condom is turned over for use with the designs made pointing outward as described [Fig. 5.b].

Plus précisément, le procédé selon le mode ‘F.E.M.’ :More precisely, the process according to the mode ‘ FEM ’:

uses a dipping mold (9) which has holes (10) to (13) of millimeter and sub-millimeter order as described [Fig. 5.a] (note that the diagram is not to scale).
according to an advantageous and non-limiting characteristic and according to claim 1 of this patent, the depth is of the order of millimeters and the other dimensions are of the order of submillimeters.
after demoulding and turning over, the projecting patterns (14) to (17) thus produced have dimensions of the order of millimeters and submillimeters as described [Fig. 5.b] (note that the diagram is not to scale).
as for mode ‘FIM’, according to claim8 of this patent, the manufacturing mold can be widened in the zones where the topographical patterns are inserted to counterbalance the increase in local elastic resistance induced by the thickness and the rigidity of the aforementioned patterns as in [Fig. 2.c].
according to an advantageous and non-limiting characteristic of the ' FEM ' mode, several different types of latex can be used for filling the holes because the latexes used in the conventional molding methods do not make it possible to fill holes of a millimetric order with the only capillary force.
according to an advantageous and non-limiting characteristic, the latex used for the first layer(s) is a standard thin layer latex which lines the edges of the grooves without filling them.
after the first layer or layers have dried, a different latex can be used to fill the grooves.
according to claim4 of this patent, according to the mode ‘WEF’, the latex used for filling the grooves is a fine porosity latex foam type latex.
according to this claim and in this embodiment, the production of the foam can be carried out according to one of the two known methods: (i) by expansion of a gas or (ii) by separation phenomenon.
according to this claim and in this embodiment, the aforementioned latex foam comprises several components (latex, surfactant, vulcanizer, additives) of a composition such that it allows the production of a foam with very fine porosity.
after deposition of the groove filling layer, the layer is wiped off so that only the hollow areas are filled with porous latex.
according to this claim and in this embodiment, after polymerization and drying, a thin layer standard latex can be used to produce the last layer which will encapsulate the raised patterns thus produced.

Ainsi, selon la revendication principale1, le mode ‘F.E.M.’ de l’invention permet la fabrication de préservatifs possédant des reliefs de taille proche ou supérieure aux seuils de discrimination tactile (en épaisseur, largeur et espacement).Thus, according to main claim 1 , the ' FEM ' mode of the invention allows the manufacture of condoms having reliefs of size close to or greater than the tactile discrimination thresholds (in thickness, width and spacing).

F.J.M. (Fabrication of molding skirts) - Application to a method of manufacturing skirts or rings according to the manufacturing technique of molding by dipping using a textured mold ([Fig. 6.a] to [Fig. 7.e])

Selon l’un des modes de réalisation de l’invention, le préservatif est réalisé à l’aide de la technique de fabrication de moulage par trempage [Ref.1]citée plus haut. La présente invention se rapporte ainsi, selon le mode ‘F.J.M.’, à un procédé de fabrication de moulage par trempage avec les différences spécifiques principales suivantes :According to one embodiment of the invention, the condom is made using the dip molding manufacturing technique [Ref.1]cited above. The present invention thus relates, according to the mode ‘FJM’, to a dip molding manufacturing process with the following main specific differences:

the mold (18) is not a smooth cylinder but has grooves (19) and (20) allowing the manufacture of topographical patterns of a size and arrangement such that these elements allow the discrimination thresholds to be reached tactile as described in the main claim of this patent (it will be noted that the diagrams are not to scale).
the number of soaks is possibly greater than that of previous techniques.
in a final phase, the condom is turned over for use with the patterns (21) to (24) pointing outward as described [Fig. 7.a] to [Fig. 7.d].

Plus précisément, le procédé selon le mode ‘F.J.M.’ :More precisely, the process according to the ' FJM ' mode:

the ' FJM ' method of manufacture uses a dipping mold (18) which has grooves (19) and (20) of millimeter order as described [Fig. 6.a] to [Fig. 6.c].

according to an advantageous and non-limiting characteristic, the grooves (19) and (20) can be continuous, their width then being equal to the perimeter of the condom as possibly in [Fig. 6.a] (sectional view), or the grooves may be discontinuous as in [Fig. 6.b] (front view).
according to an advantageous and non-limiting characteristic, the width of the aforesaid grooves allows the filling of the grooves by the latex according to a phenomenon of capillarity.
according to an advantageous and non-limiting characteristic and according to claim10 of this patent, the grooves (20) are dug with an angle varying between 10 and 45°, as described in [Fig. 6.c].
according to claim9 of this patent, the depth of the aforesaid grooves (19) and (20) can be of the order of half of the tactile discrimination threshold in thickness, the other dimensions of the topographical elements remaining of the order of the discrimination thresholds, because the topographic elements (21) to (24), as described in [Fig. 7.e], will be folded during their functional use and will double the dimensional perception of the thickness of the skirts.
according to an advantageous and non-limiting characteristic, one to several additional dippings make it possible to fill the grooves and to obtain a mechanically resistant skirt.
according to an advantageous and non-limiting characteristic, the aforesaid grooves do not have a constant depth, the edges being shallower in order to improve mold release and to offer sufficient resistance to tearing during the future elongation of the condom.
according to an advantageous and non-limiting characteristic, the aforesaid grooves can form a complete ring around the condom. After turning the condom over, annular skirts or rings (22) are obtained as in [Fig. 7.b].
according to an advantageous and non-limiting characteristic, the aforesaid grooves may not form a complete ring around the condom, but make it possible to produce discontinuous skirts (23) and (24) as described [Fig. 7.c] and [Fig. 7.d] (remember that the diagrams are not to scale).
according to claim 8 of this patent, the manufacturing mold can be widened in the zones where the topographical patterns are made to counterbalance the increase in local elastic resistance induced by the thickness and the rigidity of the aforesaid patterns.
according to claim 10 of this patent, the aforesaid grooves (20) can be arranged in a manner not perpendicular to the axis of symmetry of the cylinder, with an inclination, as described in [Fig. 6.c]. After reversal, the result (24) described in [Fig. 7.d]. According to the claim, this arrangement makes it possible to increase the sensory perception of the patterns.
according to claim 4 of this patent, as for the ' FEM ' mode, after drying of the first layer(s) of standard latex, a different latex can be used to fill the grooves, namely a latex of the latex foam type , the last layer being made with a standard latex for encapsulation.

F.J.C. (Manufacturing Skirts Bonding) - Application to a mode of Manufacturing according to a technique of Bonding Skirts. ([Fig. 8.a] and [Fig. 8.b])

Selon l’un des modes de réalisation de l’invention, le préservatif est réalisé à l’aide d’une technique de collage de jupes sur un préservatif existant (1) comme représenté et (rappelons que les schémas ne sont pas à l'échelle).
La présente invention se rapporte ainsi, selon le mode ‘F.J.C.’ (Fabrication Jupes Collage), à un procédé de fabrication utilisant des éléments préfabriqués (25) que nous appelons ‘jupes’ et tels que définis et avec les caractéristiques suivantes :According to one of the embodiments of the invention, the condom is made using a technique of gluing skirts onto an existing condom (1) as shown and (remember that the diagrams are not to scale).
The present invention thus relates, according to the mode ‘FJC’ (Fabrication Skirts Collage), to a manufacturing process using prefabricated elements (25) which we call ‘skirts’ and as defined and with the following characteristics:

according to an advantageous and non-limiting characteristic, the support is an existing condom (1) placed on a phallic mould.
according to an advantageous and non-limiting characteristic, the skirts (25) are of elastomeric nature and have a high elongation capacity.
according to an advantageous and non-limiting characteristic, the skirts form a ring around the condom.
according to an advantageous and non-limiting characteristic, the skirts (25) do not form a continuous ring around the condom in order to avoid bringing too much elastic resistance provided by the gluing of the patterns on the surface of the support condom.
according to claim 8 of this patent, the manufacturing mold can be widened in the zones where the topographical patterns are made to counterbalance the increase in local elastic resistance induced by the thickness and the rigidity of the aforesaid patterns.
according to another advantageous and non-limiting characteristic, the skirts (25) are glued over the width of the skirt with a thickness and height of glue (26) as shown [Fig. 8.b] (remember that the diagrams are not to scale).

Plus précisément :More precisely :

according to main claim 1 , the ' FJC ' (Fabrication Skirts Bonding) embodiment of the invention allows the manufacture of condoms having reliefs of size close to or greater than the tactile discrimination thresholds (in height, width and spacing). Thus, the skirts (25) preferably have topographic dimensions of the order of millimeters in thickness and of the order of submillimeters in length and width, as well as in spacing.
according to claim9 of this patent, the thickness of the skirts (25) may possibly be less than a millimeter because the topographic elements thus produced, as described [Fig. 7.e], will be folded during their functional use and will double the dimensional perception.
according to an advantageous and non-limiting characteristic, the annular arrangement of the skirts is characterized in that it returns the repeated perception of several unfoldings of the foreskin.

F.R.C. (Folding Bonding Manufacturing) - Application to a Manufacturing method using a Folding and Bonding technique ([Fig. 9.a] to [Fig. 9.e])

Selon l’un des modes de réalisation de l’invention, le préservatif est réalisé à l’aide d’une technique de fabrication de jupes par repli et collage de parties d’un préservatif standard sur lui-même. La présente invention se rapporte ainsi, selon le mode ‘F.R.C.’ (Fabrication Repli Collage), à un procédé de fabrication utilisant un préservatif existant (1) dont certaines parties sont repliées et collées sur elles-mêmes pour former des jupes comme décrit à .
NB : Dans les schémas à on n’a représenté qu’une seule rainure. Rappelons également que les schémas ne sont pas à l'échelle.According to one of the embodiments of the invention, the condom is made using a technique of manufacturing skirts by folding and gluing parts of a standard condom on itself. The present invention thus relates, according to the mode ‘FRC’ (Fabrication Repli Collage), to a manufacturing process using an existing condom (1) of which certain parts are folded and glued on themselves to form skirts as described at .
NB: In the diagrams at only one groove has been shown. Also remember that the diagrams are not to scale.

Le procédé comporte les étapes suivantes :The process comprises the following steps:

according to an advantageous and non-limiting characteristic, the initial support is an existing condom (1) placed on a phallic mold (27).
according to claim 7 of this patent, the mold (27) has grooves (29) allowing certain areas of the condom to be sucked using a vacuum suction technique through channels (28) connected to the grooves ( 29) as shown schematically [Fig. 9.a] (sectional view of the mould). According to this claim, the grooved mold has a central suction channel (28) and tree-like channels which allow localized suction of the condom into the grooves to form the skirts. During demoulding, the vacuum will be replaced by a jet of positive pressure to eject the condom.
according to claim 10 of this patent, the aforesaid grooves can be dug with an angle varying between 10 and 45°.
according to an advantageous and non-limiting feature, once aspirated as in [Fig. 9.b], the skirts thus formed are filled according to two options:
according to a first option, the skirts formed by suction can be filled by injection of an elastomeric adhesive (30) such as in [Fig. 9.c]. The aforementioned glue is suitable for bonding the condom manufacturing material to itself, of a fluidity allowing its diffusion and of biocompatible quality after drying because it will possibly be in contact with the skin. According to a variant of this option, a layer of final encapsulation latex makes it possible to fill the residual voids and to avoid using a biocompatible glue.
according to a second option, the skirts formed by suction can be filled by dipping in a latex which also forms an encapsulation layer (31) above the assembly as in [Fig. 9.d].
after drying and turning the condom over, annular skirts (32) are obtained as shown schematically [Fig. 9.e].

Plus précisément :More precisely :

according to main claim 1 , the ' FRC ' (Fabrication Repli Bonding) embodiment of the invention allows the manufacture of condoms having reliefs of size close to or greater than the discrimination thresholds.
the skirts (32) preferably have topographic dimensions of the order of millimeters in thickness and of the order of submillimeters in length and width, as well as in spacing.
according to claim9 of this patent, the thickness of the skirts (32) produced by folding and gluing may possibly be less than a millimeter because the topographic elements thus produced, as described in [Fig. 7.e], will be folded during their functional use and will double the dimensional perception.
according to several advantageous and non-limiting characteristics, the glue (30) is: (1) suitable for bonding the condom manufacturing material to itself, (2) of a fluidity allowing its diffusion in the skirt as in [Fig . 9.c], (3) of biocompatible quality or not depending on whether a final layer of latex encapsulates the whole.
according to another advantageous and non-limiting characteristic, the glue (30) can be replaced by dipping in a latex which fills the voids and also forms an encapsulation layer (31).

Claims

Principle of manufacturing condoms offering tactile sensations superior to natural conditions, characterized in that the condoms (1) have reliefs (2) whose dimensions are located at the level of the tactile discrimination thresholds, namely millimetric heights as well as submillimeter widths and spacings. This claim is based on the possibility of claiming the use of a scientific discovery or theory for a practical application because it can be considered as an invention according to the INPI Examination Guidelines ( exclusions L611-10 CPI - Directives examination of the INPI, IC-VII 1.1 and Tribunal de Grande Instance of Paris, July 3, 2014 ). Thus, according to the present claim, we observe that the tactile discrimination thresholds at the level of the genital organs are characterized in that they are of the order of millimeters in height and submillimeters for the other dimensions and that the condoms must have reliefs of dimensions close to the tactile discrimination thresholds in order to be able to offer tactile sensations superior to natural conditions (absence of a condom).

Method according to claim 1 of manufacturing by inserting topographic elements (6) between two coating layers (5) and (8) using the technique of molding by dipping, characterized according to claim 1 in that the topographic elements (6 ) have dimensions located at or beyond the tactile discrimination thresholds and characterized according to the present claim in that the topographical elements (6) are placed on the latex film (5) before drying. The film remaining 'wet', the topographic elements will adhere to the sticky film. According to this same claim, the topographical elements (6) are placed on the sides of the cylinder by means of several distribution devices (7) characterized in that they hold the elements by means of a vacuum suction system, the vacuum being cut off when the elements adhere to the film.

Process according to Claims 1 and 2 of Manufacture by Insertion of topographic elements (6) between two coating layers (5) and (8) using the technique of Molding by dipping, characterized in that the material of the inserted topographic elements, may be of the latex foam type. Thus, according to an advantageous characteristic deriving from their porosity, the aforesaid topographical elements made of latex foam have a greater elongation capacity than the latex of the encapsulation films.

Method according to claim 1 for the manufacture of projecting topographical elements (14) to (17) using the dipping molding technique, characterized in that the holes (10) to (13) make it possible to manufacture topographical elements (14) (17) whose dimensions are located at or beyond the tactile discrimination thresholds. Manufacturing process, on the other hand characterized in that, after drying the first layer or layers of standard latex (5), a different latex is used to fill the holes or grooves, namely a latex of the fine porosity latex. The last layer is made with a standard latex for encapsulation.

Process according to claim 1 for the manufacture of skirts by molding using textured moulds, characterized in that the grooves (19) and (20) make it possible to manufacture topographic elements (21) to (24) whose dimensions are located at or beyond tactile discrimination thresholds. Manufacturing process, on the other hand characterized in that, after drying of the first layer or layers of standard latex (5), a different latex is used to fill the grooves, namely a latex of the latex foam type with fine porosity. The last layer is made with a standard latex for encapsulation.

Method according to claim 1 for the manufacture of skirts (25) by gluing using an elastomeric glue (26) on a prefabricated condom (1), characterized in that the skirts have dimensions located at or beyond tactile discrimination thresholds. The skirts (25) are manufactured separately, they are elastomeric in nature and have a high elongation capacity.

Method according to claim 1 for manufacturing by Folding and Gluing parts of a prefabricated standard condom (1) folded on itself, characterized in that the condom (1) is placed on a grooved mold (27) which comprises a central suction channel (28) and tree channels connected to the grooves (29) which allow localized suction of the condom into the grooves (29) to form skirts (32) after bonding or encapsulation and turning. During demoulding, the vacuum can advantageously be replaced by positive pressure to eject the condom. Manufacturing process, according to a first option, characterized in that the skirts formed by suction can be filled by injection of an elastomeric glue (30). The aforesaid glue is suitable for bonding the manufacturing material of the condom on itself, of a high fluidity allowing its diffusion in the skirt formed by folding and of biocompatible quality after drying, cross-linking or hardening because it will be in contact with the skin. . Manufacturing process, according to a second option, characterized in that the skirts formed by suction can also be filled by dipping in a latex which then forms an encapsulation layer (31) above the assembly.

Manufacturing method according to any one of the preceding claims, characterized in that the manufacturing molds (4), (9), (18) and (27) can be widened in the areas where the topographical patterns are created to counteract the increase in local elastic resistance induced by the thickness and rigidity of the patterns created or inserted. Knowing that the diameter of condoms is generally adjusted to approximately 85% of the diameter of the penis, we can estimate that the bulge necessary for compensation of resistance is of the order of 1 to 2.5 mm depending on the size.

Manufacturing process according to any one of the preceding claims, characterized in that the thickness of the topographic elements, non-exclusively (21) to (25) and (32), can be of the order of half the threshold of tactile discrimination because the topographical elements produced will be folded up during their functional use and will thus double the sosesthetic perception of the thickness of the skirts or patterns.

Manufacturing process according to any one of the preceding claims, characterized in that a way of arranging the patterns, rings and skirts in an angular manner, and this in a non-exclusive manner, makes it possible to increase the somatosensory perception of the patterns and facilitate demoulding.
