Abstract
Description
- 1 - DESCR~ P IGnl La présente invention concerne un dispositif pour ouvrir la cuticule (l'enveloppe extérieure rigide, plus communément appelé carapace ) des crevettes afin de faciliter l'extraction de la chair sans l'abîmer. The present invention relates to a device for opening the cuticle (the rigid outer shell, more commonly known as shell) shrimp to facilitate the extraction of the flesh without damaging it.
L'ouverture des crevettes est traditionnellement effectuée de deux manières : À l'aide des doigts du consommateur. La réussite de l'exercice dépend de la dextérité de l'utilisateur et n'évite jamais le risque de salissure. À l'aide d'un couteau et d'une fourchette. Les couverts traditionnels ne sont pas adaptés à la décortication des crevettes. lis supposent une grande dextérité pour éviter que la crevette ne tourne sous l'utilisation du couteau, pour éviter de déchiqueter la chair de l'animal, pour éviter de se salir, ou encore bien inciser la carapace pour ne pas passer trop de temps à la découper et ne pas en faire de copeaux. En outre, les couteaux spécialisés sont souvent circonscrits une utilisation bien spécifique. Ils sont donc le plus souvent utilisés en compléments de couverts classiques. 15 Le dispositif selon l'invention permet de remédier à ces inconvénients. Il comporte en effet selon une première caractéristique, une lame de scalpel supplémentaire et complémentaire à l'extrémité de la pointe du couteau. En empoignant le couteau et en le retournant, de sorte à placer la cuticule de la crevette entre 20 le tranchant du scalpel (tourné vers le haut) et l'extrémité du dos de la lame majeure on peut, par levier ou simple glissement, inciser de manière nette et précise la cuticule abdominale de l'animal tout en préservant sa chair. Le manche du couteau sert de levier et permet de démultiplier l'effort. Tout en garantissant une coupe nette et précise, la lame de scalpel n'empêche pas une utilisation classique du couteau. En effet, en le retournant celui-ci peut 25 servir de couteau ordinaire, sans que la lame additionnelle ne dérange son utilisation, pour couper la queue et la tête de l'animal par exemple ou continuer le repas. Shrimp opening is traditionally done in two ways: Using the fingers of the consumer. The success of the exercise depends on the dexterity of the user and never avoids the risk of soiling. Using a knife and a fork. Traditional cutlery is not suitable for shrimp decortication. They assume great dexterity to prevent the shrimp from turning under the knife, to avoid shredding the flesh of the animal, to avoid getting dirty, or to incise the carapace so as not to spend too much time cut it out and do not make chips. In addition, specialized knives are often circumscribed a very specific use. They are therefore most often used in classic cutlery complements. The device according to the invention overcomes these disadvantages. It comprises in fact according to a first feature, an additional scalpel blade and complementary to the end of the tip of the knife. By grasping the knife and turning it, so as to place the cuticle of the shrimp between the cutting edge of the scalpel (facing upwards) and the end of the back of the major blade, it is possible, by lever or simple sliding, to incise in a clear and precise way the abdominal cuticle of the animal while preserving its flesh. The handle of the knife serves as a lever and can increase the effort. While ensuring a clean and precise cut, the scalpel blade does not prevent a conventional use of the knife. Indeed, by turning it can be used as ordinary knife, without the additional blade does not disturb its use, to cut the tail and head of the animal for example or continue the meal.
Les dessins annexés illustrent l'invention : La figure 1 représente les différentes pièces de l'invention séparée: la lame additionnelle de 30 scalpel, la pièce amovible, la vis et le profil du couteau côté empreintes. La figure 2 représente le dispositif de l'invention : le profil du couteau monté avec toutes les pièces assemblées. The accompanying drawings illustrate the invention: FIG. 1 shows the various parts of the invention separated: the additional scalpel blade, the removable part, the screw and the profile of the impression side knife. Figure 2 shows the device of the invention: the profile of the knife mounted with all the assembled parts.
En référence à ces dessins, le dispositif comporte une lame de scalpel (1) standard 35 (mettre les références de la lame) située de sorte que le tranchant soit dirigé vers le dos de la lame majeure (2) et forme une échancrure à l'extrémité du couteau (3). La pointe de la lame de scalpel arrive à l'extrémité de la ligne que forme le tranchant de la lame majeure ce qui ne rend pas le couteau plus dangereux qu'un couteau tranchant traditionnel. -2- La lame de scalpel est changeable pour allonger au maximum la durée de vie de l'objet: Sur le méplat de la lame majeure une petite pièce amovible (4) permet de maintenir la lame de scalpel. En retirant cette pièce on trouve : l'empreinte positive (5) du trou de la lame de scalpel qui permet de calter cette dernière, ainsi que deux ergots (6) pour garantir le bon positionnement de la lame, assurant ainsi un maximum de sécurité. Une petite vis (7) referme la pièce amovible. La vis passe par le trou de la lame de scalpel et traverse l'épaisseur de la lame majeure (2). Des stries en amont (8) sur le manche du couteau permettent de protéger les doigts de l'utilisateur et éviter qu'il ne dérape et ne se blesse. La longueur du manche et la position de l'échancrure (3) sont telles qu'une faible pression exercée par l'utilisateur sur le manche retourné (la lame majeure (2) vers le haut) est démultipliée et permet de fendre sur toute sa longueur la carapace de la crevette et évitant soigneusement le contact de la chair. L'utilisation du couteau dépend du sens dans lequel il est utilisé : La lame majeure (2) vers le haut permet de décortiquer les crevettes en s'aidant de la 15 saillie créé par la lame additionnelle de scalpel. - La lame majeure (2) vers le bas permet une utilisation classique du couteau pour sectionner la queue et la tête de la crevette par exemple. Referring to these drawings, the device comprises a standard scalpel blade (1) (set the blade references) located so that the cutting edge is directed towards the back of the major blade (2) and forms a notch end of the knife (3). The tip of the scalpel blade comes to the end of the line that forms the edge of the major blade which does not make the knife more dangerous than a traditional sharp knife. -2- The scalpel blade is changeable to maximize the life of the object: On the flat of the major blade a small removable part (4) keeps the scalpel blade. By removing this piece we find: the positive impression (5) of the hole of the scalpel blade which allows to calibrate the latter, and two pins (6) to ensure the proper positioning of the blade, thus ensuring maximum safety . A small screw (7) closes the removable part. The screw passes through the hole of the scalpel blade and passes through the thickness of the major blade (2). Streaks upstream (8) on the handle of the knife can protect the user's fingers and prevent it from slipping and injury. The length of the handle and the position of the notch (3) are such that a low pressure exerted by the user on the returned handle (the major blade (2) upwards) is multiplied and allows to split all over its shrimp carapace length and carefully avoiding the contact of the flesh. The use of the knife depends on the direction in which it is used: The major blade (2) upwards allows to shell the shrimps with the help of the protrusion created by the additional blade of the scalpel. - The major blade (2) downwards allows a classic use of the knife to cut the tail and shrimp head for example.
À titre d'exemple non-limitatif, le couteau aura des dimensions de l'ordre de 194mm De 20 longueur. As a non-limiting example, the knife will have dimensions of the order of 194 mm in length.
Le dispositif selon l'invention est particulièrement destiné à l'ouverture des cuticules des crevettes. The device according to the invention is particularly intended for opening prawn cuticles.
