Description

BERCEAU OUVRABLE POUR UN DISPOSITIF D'OPERCULAGE DE RECIPIENTS DIVERS OPENABLE CRADLE FOR A SEALING DEVICE OF VARIOUS CONTAINERS
DOMAINE TECHNIQUE :TECHNICAL AREA :
La présente invention concerne le domaine technique du conditionnement de produits divers et, plus particulièrement, de produits alimentaires dans le cadre de fabrications artisanales ou semi-industrielles.The present invention relates to the technical field of packaging various products and, more particularly, food products in the context of artisanal or semi-industrial manufacturing.
TECHNIQUE ANTERIEURE :PRIOR TECHNIQUE:
Dans le domaine ci-dessus, il est connu de mettre en oeuvre des contenants de diverses formes qu'il convient de fermer ou d'operculer après remplissage, afin de préserver l'intégrité de leur contenu. Il est connu, par exemple, des contenants du type barquettes présentant une plage périphérique, qui sont fermés au moyen d'un opercule thermoscellable fixé sur cette plage.In the above field, it is known to use containers of various shapes which should be closed or sealed after filling, in order to preserve the integrity of their content. It is known, for example, containers of the type trays having a peripheral range, which are closed by means of a heat sealable seal fixed on this range.
Il est proposé, afin de réaliser l'opération de thermoscellage de l'opercule sur la barquette, un dispositif présentant un socle pourvu d'un logement de réception d'au moins un contenant ou barquette. Sur ce socle est fixé un châssis basculant depuis une position relevée jusqu'à une position abaissée, dans laquelle les moyens de chauffage sont pressés contre l'opercule et le contenant à fermer. La manoeuvre du châssis mobile est, plus généralement, assurée par un opérateur qui détermine, par l'intensité et la durée de l'effort qu'il exerce manuellement sur le châssis, la pression de scellage et le temps de chauffage de l'opercule thermoscellable. Afin que le châssis relevé occupe une position stable sans risque de fermeture intempestive sur les mains de l'utilisateur, lors de la mise en place du mouvement, le mouvement du châssis présente, le plus généralement, une amplitude supérieure à 90°. Enfin, le socle comprend, au niveau du logement de réception, un berceau présentant au moins une empreinte ouverte sur le dessus pour la réception d'un contenant à operculer.It is proposed, in order to carry out the heat sealing operation of the lid on the tray, a device having a base provided with a housing for receiving at least one container or tray. On this base is fixed a tilting frame from a raised position to a lowered position, in which the heating means are pressed against the cover and the container to be closed. The maneuvering of the mobile chassis is, more generally, ensured by an operator who determines, by the intensity and the duration of the force which he exerts manually on the chassis, the sealing pressure and the heating time of the cover sealable. So that the raised chassis occupies a stable position without risk of inadvertent closing on the hands of the user, when the movement is put in place, the movement of the chassis generally has an amplitude greater than 90 °. Finally, the base comprises, at the reception housing, a cradle having at least one imprint open on the top for the reception of a container to be sealed.
La mise en place du contenant par l'utilisateur s'effectue alors par le dessus en insérant ledit contenant dans l'empreinte pour, dans le cas de l'utilisation de barquettes en tant que contenants, amener la plage périphérique en appui sur les bords de l'empreinte.The installation of the container by the user is then carried out from above by inserting said container into the imprint for, in the case of the use of trays as containers, bring the peripheral area to bear on the edges of the imprint.
Après l'introduction du contenant dans l'empreinte, l'utilisateur met en place l'opercule et procède à sa fixation. De manière générale, la mise en place du contenant, dans le dispositif d'operculage, est effectuée après remplissage du contenant et l'opération, consistant à venir enchâsser le contenant dans l'empreinte, peut s'avérer fort délicate lorsque le contenant présente une grande capacité et/ou que son contenu est chaud. En effet, l'utilisateur doit alors porter le contenant par ses bords supérieurs ou sa plage périphérique qui n'offre pas une prise importante.After the introduction of the container into the imprint, the user sets up the seal and proceeds to fix it. In general, the positioning of the container in the sealing device is carried out after filling the container and the operation, consisting in encasing the container in the impression, can prove to be very delicate when the container has a large capacity and / or its contents are hot. Indeed, the user must then carry the container by its upper edges or its peripheral area which does not offer a significant grip.
Il apparaît donc le besoin de disposer de moyens permettant de faciliter la mise en place du contenant dans le berceau du logement de réception.It therefore appears the need to have means to facilitate the positioning of the container in the cradle of the receiving housing.
EXPOSE DE L'INVENTION :PRESENTATION OF THE INVENTION:
Afin de répondre à cette attente, l'invention vise un berceau pour dispositif d'operculage de contenants divers, qui autorise une introduction latérale du contenant, de sorte qu'il n'est plus nécessaire de tenir ce dernier par ses bords supérieurs, mais qu'il est alors possible de le supporter par son fond lors de sa mise en place. Afin d'atteindre cet objectif et d'apporter une solution aux inconvénients des dispositifs d'operculage selon l'art antérieur, l'invention vise donc un berceau pour un dispositif d'operculage de contenants divers, du type présentant au moins une empreinte de réception d'un contenant.In order to meet this expectation, the invention relates to a cradle for a sealing device for various containers, which allows lateral introduction of the container, so that it is no longer necessary to hold the latter by its upper edges, but that it is then possible to support it by its bottom during its installation. In order to achieve this objective and to provide a solution to the drawbacks of lidding devices according to the prior art, the invention therefore relates to a cradle for a lidding device for various containers, of the type having at least one imprint of receipt of a container.
Selon l'invention, ce berceau est caractérisé en ce qu'il comprend au moins un côté mobile articulé sur le berceau pour autoriser une ouverture latérale de l'empreinte et permettre une introduction latérale du contenant.According to the invention, this cradle is characterized in that it comprises at least one movable side articulated on the cradle to allow lateral opening of the impression and allow lateral introduction of the container.
Par ailleurs, selon la quantité de produits à conditionner, il peut être nécessaire de recourir à des contenants de tailles différentes, tant en hauteur qu'en largeur. Il est donc alors nécessaire de disposer d'un berceau qui soit à même de prendre en charge des contenants de dimensions variables.Furthermore, depending on the quantity of products to be packaged, it may be necessary to use containers of different sizes, both in height and in width. It is therefore necessary to have a cradle which is able to support containers of variable dimensions.
Afin de répondre à cette attente, selon une autre caractéristique de l'invention, le berceau comprend des moyens de réglage de la taille de l'empreinte. L'invention vise également à proposer un nouveau dispositif pour l'operculage de contenants divers qui permet une introduction latérale du contenant.In order to meet this expectation, according to another characteristic of the invention, the cradle comprises means for adjusting the size of the imprint. The invention also aims to propose a new device for sealing various containers which allows lateral introduction of the container.
Afin d'atteindre cet objectif, l'invention concerne, également, un dispositif du type comprenant un socle pourvu d'un logement de réception d'au moins un contenant et un châssis mobile pourvu de moyens pour fixer un opercule sur le contenant.In order to achieve this objective, the invention also relates to a device of the type comprising a base provided with a housing for receiving at least one container and a movable frame provided with means for fixing a cover on the container.
Selon l'invention, ce dispositif est caractérisé en ce que le logement de réception comprend des moyens d'ouverture latérale et un berceau présentant au moins une empreinte qui comprend au moins un côté mobile articulé pour autoriser une ouverture latérale de l'empreinte et permettre une introduction latérale du contenant dans le logement.According to the invention, this device is characterized in that the receiving housing comprises lateral opening means and a cradle having at least one footprint which comprises at least one articulated mobile side to allow lateral opening of the footprint and allow a lateral introduction of the container into the housing.
Selon une caractéristique de l'invention, le berceau fait partie intégrante du socle du dispositif d'operculage.According to a characteristic of the invention, the cradle is an integral part of the base of the sealing device.
Selon une autre caractéristique de l'invention, le berceau est amovible et peut être retiré du socle du dispositif de manière à, par exemple, pouvoir être remplacé par un autre berceau de taille et forme différentes.According to another characteristic of the invention, the cradle is removable and can be removed from the base of the device so that, for example, it can be replaced by another cradle of different size and shape.
Diverses autres caractéristiques ressortent de la description faite ci- dessous en référence aux dessins annexés qui montrent, à titre d'exemples non limitatifs, des formes de réalisation de l'objet de l'invention.Various other characteristics will emerge from the description given below with reference to the appended drawings which show, by way of nonlimiting examples, embodiments of the subject of the invention.
BREVE DESCRIPTION DES DESSINS :BRIEF DESCRIPTION OF THE DRAWINGS:
La fig. 1 est une perspective montrant une forme préférée de réalisation d'un dispositif d'operculage pourvu d'un berceau conforme à l'invention.Fig. 1 is a perspective view showing a preferred embodiment of a sealing device provided with a cradle according to the invention.
La fig. 2 est une vue selon le plan H-H de la fig. 1 montrant, plus particulièrement, la forme de réalisation de berceaux conformes à l'invention.Fig. 2 is a view along the H-H plane of FIG. 1 showing, more particularly, the embodiment of cradles according to the invention.
La fig. 3 est une élévation selon le plan 10-10 de la fig. 1.Fig. 3 is an elevation along the plane 10-10 of FIG. 1.
La fig. 4 illustre une autre forme de réalisation d'un dispositif selon l'invention, plus particulièrement destiné à un conditionnement, sous vide relatif ou atmosphère contrôlée, de contenants divers. Les fig. 5 à 7 illustrent des formes de réalisation d'un berceau ouvrable amovible selon l'invention. MEILLEURE MANIERE DE REALISER L'INVENTION :Fig. 4 illustrates another embodiment of a device according to the invention, more particularly intended for packaging, under relative vacuum or controlled atmosphere, of various containers. Figs. 5 to 7 illustrate embodiments of a removable opening cradle according to the invention. BEST WAY TO IMPLEMENT THE INVENTION:
Comme le montrent les fig. 1 à 3, le dispositif pour l'operculage de contenants divers, conforme à l'invention et désigné dans son ensemble par la référence 1, comprend un socle 2 pourvu d'un logement 3 de réception d'un contenant 4 destiné à être operculé. Selon l'exemple illustré, le contenant 4 est constitué par une barquette, de forme sensiblement parallélépipèdique, présentant une aile ou plage périphérique 5 pour le scellage d'un opercule.As shown in fig. 1 to 3, the device for sealing various containers, according to the invention and generally designated by the reference 1, comprises a base 2 provided with a housing 3 for receiving a container 4 intended to be sealed . According to the example illustrated, the container 4 is constituted by a tray, of substantially parallelepiped shape, having a wing or peripheral area 5 for sealing a seal.
Le dispositif 1 comprend, pour la réception d'un tel contenant, au niveau du logement 3, un berceau 6 dans lequel le contenant vient s'engager pour venir reposer, par sa plage périphérique 5, dans une empreinte 7 présentée par le berceau 6.The device 1 comprises, for the reception of such a container, at the level of the housing 3, a cradle 6 in which the container engages to come to rest, by its peripheral surface 5, in an imprint 7 presented by the cradle 6 .
Comme cela ressort plus particulièrement de la fig. 2, l'empreinte 7 est ouverte sur le dessus.As is more particularly apparent from FIG. 2, the imprint 7 is open on the top.
Le dispositif pour l'operculage du contenant 4 comprend, également, un châssis mobile 8 pourvu de moyens 9 pour fixer un opercule ou analogue sur le contenant 4. Le châssis 8 est relié au socle 2, de manière à pouvoir être déplacé entre une position d'ouverture et une position de fermeture dans laquelle les moyens de fixation sont appliqués contre l'opercule.The device for sealing the container 4 also comprises a movable frame 8 provided with means 9 for fixing a cover or the like on the container 4. The frame 8 is connected to the base 2, so that it can be moved between a position opening and a closed position in which the fixing means are applied against the cover.
Conformément à une caractéristique essentielle de l'invention, le berceau 6 est ouvrable. Selon une forme de réalisation préférée mais non exclusive, le berceau 6 est intégré au socle 2 et comprend deux demi-empreintes dont l'une 15 est solidaire du socle 2, tandis que l'autre 16 est mobile en rotation, de manière à permettre une ouverture du berceau.In accordance with an essential characteristic of the invention, the cradle 6 can be opened. According to a preferred but not exclusive embodiment, the cradle 6 is integrated into the base 2 and comprises two half-cavities, one of which is integral with the base 2, while the other 16 is movable in rotation, so as to allow an opening of the cradle.
Selon l'exemple illustré, les deux demi-empreintes 15 et 16 présentent une forme en "L" et la demi-empreinte 15 définit deux côtés 15ι et 152 fixes de l'empreinte 7, tandis que la demi-empreinte mobile 16 définit deux côtés mobiles 16l5 162 de cette même empreinte 7. Comme le montre plus particulièrement la fig. 2, les deux demi- empreintes 15 et 16 sont disposées tête-bêche.According to the example illustrated, the two half-cavities 15 and 16 have an "L" shape and the half-cavity 15 defines two fixed sides 15ι and 15 2 of the cavity 7, while the movable half-cavity 16 defines two movable sides 16 15 16 2 of this same imprint 7. As shown more particularly in FIG. 2, the two half-impressions 15 and 16 are arranged head to tail.
Afin de permettre un pivotement de la demi-empreinte mobile 16 dans un plan parallèle au plan d'appui P, pour la plage 5, défini par l'empreinte 7 et le berceauTo allow pivoting of the movable half-footprint 16 in a plane parallel to the support plane P, for the range 5, defined by the footprint 7 and the cradle
6, la demi-empreinte 16 est fixée sur la partie du socle 2 définissant le berceau 6 par un moyen d'articulation 17, tel que, par exemple mais non exclusivement, un pivot d'axe sensiblement vertical. Bien entendu, la demi-empreinte mobile 16 pourrait être fixée sur le berceau 6 par un tout autre moyen d'articulation lui permettant de s'ouvrir selon un mouvement contenu, de préférence mais non exclusivement, dans un plan sensiblement horizontal.6, the half-cavity 16 is fixed on the part of the base 2 defining the cradle 6 by an articulation means 17, such as, for example but not exclusively, a pivot with a substantially vertical axis. Of course, the movable half-cavity 16 could be fixed on the cradle 6 by any other means of articulation allowing it to open in a contained movement, preferably but not exclusively, in a substantially horizontal plane.
Ainsi, par sa liaison articulée avec le berceau 6, la demi-empreinte mobile 16 peut se déplacer entre une position fermée A, illustrée en trait mixte à la fig. 2, et une position ouverte B, également illustrée en trait mixte à la fig. 2 et représentée à la fig. 1 Selon une autre caractéristique de l'invention, dont la fonction ressortira de la suite, le logement de réception 3 est ouvert latéralement au niveau de l'une de ses faces correspondant au côté mobile ou articulé 162 de l'empreinte, comme le montre la fig. 3.Thus, by its articulated connection with the cradle 6, the movable half-cavity 16 can move between a closed position A, illustrated in phantom in FIG. 2, and an open position B, also illustrated in phantom in FIG. 2 and shown in FIG. 1 According to another characteristic of the invention, the function of which will emerge from the following, the receiving housing 3 is open laterally at one of its faces corresponding to the movable or articulated side 16 2 of the imprint, as the shows fig. 3.
La mise en œuvre d'un tel berceau ouvrable 6 sur le dispositif 1, conforme à l'invention, permet, de manière très avantageuse, de faciliter les opérations de mise en place et du retrait du contenant 4 à operculer.The implementation of such an opening cradle 6 on the device 1, according to the invention, very advantageously makes it possible to facilitate the operations of placing and removing the container 4 to be sealed.
Ainsi, un utilisateur du dispositif 1 peut, en maintenant d'une main le contenant 4 par son fond, ouvrir, avec l'autre main, la demi-empreinte mobile 16 dans le sens de la flèche Fi, de manière à écarter les deux côtés mobiles 16ι et 162 de l'empreinte 7.Thus, a user of the device 1 can, with one hand holding the container 4 by its bottom, open, with the other hand, the movable half-impression 16 in the direction of the arrow Fi, so as to separate the two movable sides 16ι and 16 2 of the imprint 7.
L'utilisateur peut alors introduire, latéralement dans le sens de la flèche F2, le contenant 4 dans le logement 3, de manière à venir le placer dans l'angle défini par les deux côtés 15ι et 152 de la demi-empreinte 15 fixe. Il doit être noté que le dégagement des côtés 16χ et 162 portés par la demi-empreinte mobile 16 facilite grandement la mise en place du contenant 4 qui est, par ailleurs, permise par l'ouverture latérale du logement 3. Cette absence de paroi latérale du logement 3 dans le prolongement d'un côté mobile de l'empreinte, définit, en quelque sorte, un moyen d'ouverture dudit logement.The user can then introduce, laterally in the direction of the arrow F 2 , the container 4 into the housing 3, so as to come and place it in the angle defined by the two sides 15ι and 15 2 of the half-cavity 15 fixed. It should be noted that the release of the sides 16χ and 16 2 carried by the movable half-cavity 16 greatly facilitates the positioning of the container 4 which is, moreover, permitted by the lateral opening of the housing 3. This absence of wall lateral of the housing 3 in the extension of a movable side of the imprint, defines, in a way, a means of opening said housing.
Tout en maintenant le contenant 4 par son fond, l'utilisateur peut ensuite refermer la demi-empreinte mobile 16 dans le sens de la flèche F3, pour l'amener en position fermée A dans laquelle l'empreinte 7 présente une forme sensiblement rectangulaire et le contenant 4 peut reposer en appui par sa plage 5 sur le berceau 6 et l'empreinte 7.While maintaining the container 4 at its bottom, the user can then close the movable half-impression 16 in the direction of the arrow F 3 , to bring it into the closed position A in which the impression 7 has a substantially shaped rectangular and the container 4 can rest by its support 5 on the cradle 6 and the imprint 7.
Une fois le berceau 6 ou l'empreinte 7 refermé, l'opérateur peut lâcher le contenant 4 et poursuivre les opérations d'operculage dudit contenant, conformément au fonctionnement du dispositif 1 qui ne rentre pas dans le cadre de la présente invention.Once the cradle 6 or the imprint 7 closed, the operator can drop the container 4 and continue the sealing operations of said container, in accordance with the operation of the device 1 which does not come within the scope of the present invention.
Selon une variante préférée de la forme de réalisation préférée illustrée aux fig. 1 à 3, le berceau 6 comprend également des moyens 18 permettant d'assurer un réglage de la taille de l'empreinte 1. Selon l'exemple illustré, ces moyens de réglage 18 sont réalisés sous la forme d'une rainure oblongue aménagée sur la demi-empreinte mobile 16 et à l'intérieur duquel passe l'axe du pivot 17. Les moyens de réglage 18 permettent alors de faire varier continûment la taille de l'empreinte 7, entre une position A d'extension maximale et une position C d'extension minimale, en faisant coulisser la demi-empreinte mobile 16 par rapport à la demi-empreinte fixe 15, tout en conservant la possibilité d'ouverture et de pivotement de la demi-empreinte mobile 16. Selon l'exemple illustré, en position d'extension minimale C, la demi- empreinte mobile 16 est située à distance de la demi-empreinte mobile 15. Toutefois, il pourrait être envisagé, qu'en position d'extension minimale C, la demi-empreinte mobile 2 soit au contact de la demi-empreinte fixe 15. De même, afin de permettre un réglage rapide et facile du berceau, il est possible de prévoir un indexage des positions de la demi-empreinte mobile 16 correspondant aux tailles des contenants les plus couramment utilisés.According to a preferred variant of the preferred embodiment illustrated in FIGS. 1 to 3, the cradle 6 also comprises means 18 making it possible to adjust the size of the imprint 1. According to the example illustrated, these adjustment means 18 are produced in the form of an oblong groove arranged on the movable half-cavity 16 and inside which the axis of the pivot 17 passes. The adjustment means 18 then make it possible to continuously vary the size of the cavity 7, between a position A of maximum extension and a position C of minimum extension, by sliding the movable half-cavity 16 relative to the fixed half-cavity 15, while retaining the possibility of opening and pivoting of the movable half-cavity 16. According to the example illustrated, in the minimum extension position C, the mobile half-impression 16 is located at a distance from the mobile half-impression 15. However, it could be envisaged that, in the minimum extension position C, the mobile half-impression 2 is in contact with the fixed half-impression 15. Similarly, af in order to allow quick and easy adjustment of the cradle, it is possible to provide indexing of the positions of the movable half-cavity 16 corresponding to the sizes of the most commonly used containers.
Selon l'exemple illustré précédemment, deux des côtés de l'empreinte 7 sont mobiles. Toutefois, conformément à l'invention, seul l'un des côtés pourrait être mobile pour permettre une ouverture de l'empreinte et son mouvement pourrait s'effectuer d'une autre manière que parallèlement au plan P.According to the example illustrated above, two of the sides of the imprint 7 are movable. However, in accordance with the invention, only one of the sides could be movable to allow an opening of the imprint and its movement could be carried out in a manner other than parallel to the plane P.
La fig. 4 illustre une autre forme de réalisation dans laquelle seul un des côtés de l'empreinte est mobile.Fig. 4 illustrates another embodiment in which only one of the sides of the imprint is movable.
Selon cet exemple, le dispositif d'operculage 1 est plus particulièrement conçu pour permettre un conditionnement sous vide relatif du contenant. A cette fin, le logement de réception 3 définit une sorte de cuve étanche. Conformément à une caractéristique essentielle de l'invention, cette cuve 3 présente une porte pivotante 20 dont la partie supérieure 21 définit un côté mobile de l'empreinte 7 et du berceau 6 intégré au socle 2. La porte 20 définit ainsi des moyens d'ouverture latérale du logement 3 pour une introduction du contenant 4, comme expliqué précédemment.According to this example, the sealing device 1 is more particularly designed to allow packaging under relative vacuum of the container. To this end, the receiving housing 3 defines a kind of sealed tank. In accordance with an essential characteristic of the invention, this tank 3 has a pivoting door 20, the upper part 21 of which defines a movable side of the cavity 7 and of the cradle 6 integrated into the base 2. The door 20 thus defines means of lateral opening of the housing 3 for an introduction of the container 4, as explained above.
Dans les exemples précédents, le berceau 6 conforme à l'invention est intégré au dispositif d'operculage. Toutefois, selon l'invention, le berceau 6 pourrait être réalisé séparément et adapté, de manière amovible ou non, sur le socle 2 du dispositif d'operculage. Les fig. 5 à 7 illustrent différentes formes de réalisation d'un tel berceau 6 amovible.In the previous examples, the cradle 6 according to the invention is integrated into the sealing device. However, according to the invention, the cradle 6 could be produced separately and adapted, removably or not, on the base 2 of the sealing device. Figs. 5 to 7 illustrate different embodiments of such a removable cradle 6.
La fig. 5 illustre un berceau 6 comprenant deux demi-empreintes 22 et 23 dont l'une 22 comprend des moyens de fixation 24 du berceau 6 sur le socle 2. Ces moyens de fixation sont, par exemple, constitués par des perçages 24 pour la mise en place de vis de fixation. L'autre demi-empreinte 23 est fixée, par un pivot 25, sur la demi-empreinte 22, de manière à autoriser une ouverture et une fermeture du berceau 6 dans le sens des flèches Fi et F3. La demi-empreinte mobile 23 comprend, par ailleurs, une série d'alésages 26 qui définissent des positions distinctes pour le pivot 25 pour permettre un réglage de l'empreinte 7 à différentes tailles de contenants pouvant être pris en charge par le berceau 6.Fig. 5 illustrates a cradle 6 comprising two half-cavities 22 and 23, one of which 22 includes means for fixing 24 of the cradle 6 on the base 2. These fixing means are, for example, constituted by bores 24 for setting fixing screw place. The other half-imprint 23 is fixed, by a pivot 25, to the half-imprint 22, so as to allow the cradle 6 to be opened and closed in the direction of the arrows Fi and F3. The movable half-footprint 23 also comprises a series of bores 26 which define distinct positions for the pivot 25 to allow adjustment of the footprint 7 to different sizes of containers that can be supported by the cradle 6.
Selon la forme de réalisation illustrée à la fig. 6, le berceau 6 présente un corps 30 en "U", destiné à être fixé sur le socle 2 du dispositif d'operculage. Le corps en "U" 30 est fermé par un côté pivotant 31, de manière à pouvoir ouvrir et fermer l'empreinte 7 pour la mise en place du contenant. Selon cet exemple, le berceau 6 comprend, également, des moyens de réglage de la taille de l'empreinte 7, formés par une traverse 32 qui coulisse dans deux rainures aménagées dans deux côtés opposés du corps 30. Ainsi, le déplacement de la traverse mobile 32, selon la direction de la flèche F5, permet de modifier la taille de l'empreinte 7.According to the embodiment illustrated in FIG. 6, the cradle 6 has a body 30 in a "U" shape, intended to be fixed on the base 2 of the sealing device. The "U" -shaped body 30 is closed by a pivoting side 31, so that the impression 7 can be opened and closed for the positioning of the container. According to this example, the cradle 6 also comprises means for adjusting the size of the imprint 7, formed by a cross member 32 which slides in two grooves arranged in two opposite sides of the body 30. Thus, the movement of the cross member mobile 32, in the direction of arrow F 5 , makes it possible to modify the size of the imprint 7.
Selon l'exemple illustré à la fig. 7, le berceau 6 comprend une traverse fixe 35, destinée à être fixée sur le socle du dispositif d'operculage. Le berceau 6 comprend, de plus, deux traverses 36 et 37 mobiles montées de manière pivotante sur la traverse 35, de manière à permettre une ouverture sur trois côtés de l'empreinte 7 définie par le berceau 6.According to the example illustrated in FIG. 7, the cradle 6 comprises a fixed cross member 35, intended to be fixed to the base of the sealing device. The cradle 6 further comprises two movable crosspieces 36 and 37 pivotally mounted on the cross-member 35, so as to allow an opening on three sides of the imprint 7 defined by the cradle 6.
Selon les exemples illustrés, le berceau 6 est mono-empreinte. Toutefois, le berceau conforme à l'invention pourrait présenter plusieurs empreintes de réception de contenants, auxquelles seraient associés à un ou plusieurs côtés articulés permettant une ouverture pour une introduction latérale des contenants.According to the examples illustrated, the cradle 6 is single-cavity. However, the cradle according to the invention could have several imprints for receiving containers, which would be associated with one or more articulated sides allowing an opening for lateral introduction of the containers.
