Abstract
Description
L'invention concerne une pince pour l'ouver- ture des mollusques bivalves et, notamment, des huî tres
Cette pince comporte deux branches articulées l'une sur 11 autre et formant entre elles une zone de pinçage, l'une des branches se prolongeant au-delà de la zone de pinçage par une lame de coupe, pince caractérisée en ce que les deux branches viennent en contact l'une de l'autre, dans la zone de pinçage, par la périphérie d'une cuvette formée dans au moins l'une des branches
Suivant une autre caractéristique de l'invention, chacune des deux branches présente une cuvette les deux branches venant en contact l'une de l'autre par la périphérie de ces cuvettes.The invention relates to tongs for opening bivalve molluscs and, in particular, oysters
This clamp has two branches articulated one on 11 another and forming between them a clamping zone, one of the branches extending beyond the clamping zone by a cutting blade, clamp characterized in that the two branches come into contact with each other, in the clamping zone, by the periphery of a bowl formed in at least one of the branches
According to another characteristic of the invention, each of the two branches has a bowl, the two branches coming into contact with one another by the periphery of these bowls.
L'invéntion est représentée à titre d'exemple non limitatif sur les dessins ci-joints, dans lesquels
- la figure 1 est une vue en élévation d'une pince conforme à l'invention,
- la figure 2 est une vue de gauche de la figure 1.The drawback is shown by way of nonlimiting example in the accompanying drawings, in which
FIG. 1 is an elevation view of a clamp according to the invention,
- Figure 2 is a left view of Figure 1.
La présente invention a pour but la réalisation d'une pince qui permette l'ouverture de mollusques bivalves et, notamment, des huîtres, de manière simple, rapide et particulièrement en réduisant le risque de production de déchets de coquilles qui pourraient nuire à la consommation de la chair. The object of the present invention is to produce tongs which allow the opening of bivalve molluscs and, in particular, oysters, in a simple, rapid manner and in particular by reducing the risk of producing shell waste which could harm consumption flesh.
Cette pince se compose de ceux branches 1 et 2 articulées suivant un axe 3 et'dont l'une des extrémités li, 2. forme la poignée de préhension pour la manipulation de la pince. This clamp consists of those branches 1 and 2 articulated along an axis 3 and 'of which one of the ends li, 2. forms the grip for handling the clamp.
Les deux autres extrémités 12, 22 des branches forment entre elles la zone de pinçage 4 du mollusque, tandis que l'une de ces branches et, en l'occurrence l'extrémité 22 se prolonge par une spatule ou lame de coupe 5. The two other ends 12, 22 of the branches form between them the nip 4 of the mollusk, while one of these branches and, in this case the end 22 is extended by a spatula or cutting blade 5.
La zone de pinçage 4 est destinée à être serrée à une. des extrémités du mollusque, à hauteur du plan de 3 oint des deux coquilles du bivalve, afin de casser la coquille. I1 se forme alors à cette extrémité une ouverture dans laquelle peut être introduite la lame de coupe 5 pour sectionner le tendon qui relie les deux coquilles et permettre l'ouverture du mollus-. The pinching zone 4 is intended to be tightened to one. from the ends of the mollusk, at the level of the 3 anointed plane of the two bivalve shells, in order to break the shell. I1 then forms at this end an opening in which can be inserted the cutting blade 5 to cut the tendon which connects the two shells and allow the opening of the mollus-.
que.than.
Conformément à 1'invention, les deux extrémités 12 et 22 des branches présentent, dans la zone de pinçage 4, des cuvettes respectivement 13, 2 qui sont réalisées pour se disposer en regard l'une de l'autre, de façon que, lorsque la pince est fermée, les bords périphériques continus des deux cuvettes viennent s'appliauer l'un contre l'autre. In accordance with the invention, the two ends 12 and 22 of the branches have, in the clamping zone 4, cups respectively 13, 2 which are made to be positioned facing each other, so that, when the clamp is closed, the continuous peripheral edges of the two bowls are applied against each other.
Cette disposition permet de pincer l'extrémité du mollusque dans la zone 4 de façon que les bords 6 situés d'un côté de la pince viennent s'appliquer sur la zone voisine de l'extrémité des deux coquilles, tandis que cette extrémité elle-même des deux coquilles est située à l'intérieur du logement formé par les deux cuvettes 13 23. L'utilisateur a alors tendance à accompagner son mouvement de serrage des branches lj et 2- par un mouvement de pivotement de ces dernières, ce qui est permis compte tenu de la profondeur des cuvettes 13 et 23. Ce mouvement combiné de serrage et de pivotement a tendance à provoquer la cassure de l'extrémité de la coquille et non pas son écrasement. This arrangement makes it possible to pinch the end of the mollusk in zone 4 so that the edges 6 located on one side of the forceps come to apply on the zone close to the end of the two shells, while this end itself even of the two shells is situated inside the housing formed by the two bowls 13 23. The user then tends to accompany his movement of tightening the branches lj and 2- by a pivoting movement of the latter, which is allowed given the depth of the bowls 13 and 23. This combined tightening and pivoting movement tends to cause the end of the shell to break and not to be crushed.
I1 en résulte que cette pince produit deux morceaux de coquille qui sont récupérés dans le logement, alors fermé, délimité par les deux cuvettes 13, 2=. Eventuellement, si des petits déchets de coquille sont formés lors de cette opération, ceux-ci sont également emprisonnés dans le logement des cuvettes et ne restent donc pas sur les coquilles du rollusque où ils pourraient geler la consommation de la chair. I1 follows that this clamp produces two pieces of shell which are recovered in the housing, then closed, delimited by the two bowls 13, 2 =. Optionally, if small shell scraps are formed during this operation, these are also trapped in the housing of the bowls and therefore do not remain on the rollusque shells where they could freeze the consumption of the flesh.
Le dispositif conforme à l'invention a donc essentiellement pour but d'inciter l'utilisateur à casser la coquille et non pas à la couper par un .simple écrasement, auquel cas les coquilles risquent de se briser en petits morceaux ou, tout au moins, de produire un orifice irrégulier entre les deux coquilles, avec production d'une quantité irportante de petits déchets. The device according to the invention therefore essentially aims to encourage the user to break the shell and not to cut it by a .simple crushing, in which case the shells may break into small pieces or, at least , to produce an irregular orifice between the two shells, with production of an important quantity of small waste.
