BAC A REISNTION
L'invention concerne un bac, notamment destiné à contenir des produits alimentaires tels que des viandes, poissons, ou autres, recouverts ou non d'une pellicule m4tallique ou de matière plastique transparente, autosoudable ou non.REISNTION TRAY
The invention relates to a tray, in particular intended to contain food products such as meat, fish, or the like, whether or not covered with a metallic film or transparent plastic material, self-sealing or not.
De tels bacs, utilisés en grandes quantités dans les étalages réfrigérés des magasins, sont ordinairement en polystyrène expansé ou carton, moulé ou découpé. Uh inconvénient majeur de ces s matériaux lorsqu'ils sont employés pour des produits alimentaires qui laissent couler du jus, du sang, ou un liquide organique quelconque est que ce liquide imprègne le support, le dégrade et favorise le développement d'odeurs et de goûts indésirables, ainsi que d'une faune microbienne d'autant plus importante que le temps de contact est long. Ceci peut rendre les produits alimentaires impropres à la consommation au bout d'un temps relativement court (en tout cas plus court que le temps de dégradation naturelle du produit alimentaire lui-même). Such bins, used in large quantities in refrigerated store shelves, are usually made of expanded polystyrene or cardboard, molded or cut. A major drawback of these materials when they are used for food products which let flow of juice, blood, or any organic liquid is that this liquid permeates the support, degrades it and promotes the development of odors and tastes. undesirable, as well as a microbial fauna all the more important the longer the contact time. This can make food products unfit for consumption after a relatively short time (in any case shorter than the time of natural degradation of the food product itself).
Le but de l'invention est de proposer un bac ne présentant pas ces inconvénients et favorisant une bonne hygiène du produit conserve. The object of the invention is to provide a container which does not have these drawbacks and which promotes good hygiene of the preserved product.
Selon l'invention, le bac comporte un fond constitué d'un matériau profilé en caissons, et des trous pratiqués dans la surface supérieure des caissons font communiquer ceux-ci avec l'intérieur du bac. According to the invention, the tank has a bottom made of a material profiled in boxes, and holes made in the upper surface of the boxes make them communicate with the inside of the tank.
Ainsi, les liquides qui s'écoulent du produit conservé sont drainés dans les caissons et ne sont plus au contact du produit lui-même. Thus, the liquids which flow from the preserved product are drained into the boxes and are no longer in contact with the product itself.
Avantageusement le bac est réalisé en une seule pièce à partir d'une plaque de matière plastique, de préférence alimentaire, extrudée en caissons, par exemple en polypropylène, polyéthylène ou autre, résistant ou non aux micro-ondes. La plaque de matière plastique peut recevoir par contrecollage une pellicule de métal doré ou argenté, ou être teintée dans la masse en couleur or, argent, ou autre, dont l'aspect ou la couleur conviennent bien aux produits alimentaires emballés. Advantageously, the tank is produced in a single piece from a plate of plastic, preferably food, extruded in boxes, for example polypropylene, polyethylene or other, resistant or not to microwaves. The plastic plate can receive by laminating a film of gold or silver metal, or be tinted in the mass in gold, silver, or other color, the appearance or color of which are well suited to packaged food products.
La plaque peut être thermoformée. Alors, les trous sont avantageusement réalisés par des poinçons portés par l'outil de thermoformage lui-même. The plate can be thermoformed. Then, the holes are advantageously made by punches carried by the thermoforming tool itself.
La plaque peut aussi être pliée. The plate can also be folded.
Les trous peuvent consister en des fentes obtenues par incision de la paroi supérieure de la plaque extrudée en caissons. The holes may consist of slots obtained by incision of the upper wall of the extruded plate in boxes.
Avantageusement, les trous sont conformés de manière à éviter toute fuite du liquide contenu dans les caissons en cas de retournement du bac. Advantageously, the holes are shaped so as to avoid any leakage of the liquid contained in the boxes in the event of the container being turned over.
Avantageusement, la plaque peut également comporter à sa partie inférieure des pieds, qui peuvent être formés par thermoformage. Advantageously, the plate can also have feet at its lower part, which can be formed by thermoforming.
Le bac de l'invention peut servir à incorporer lui-même, dans ses caissons, un produit destiné à favoriser la conservation, un produit antiseptique, un produit odoriférant, un produit absorbant, un produit humidifiant, etc. The container of the invention can be used to incorporate, into its boxes, a product intended to promote preservation, an antiseptic product, an odoriferous product, an absorbent product, a humidifying product, etc.
Le bac de l'invention peut aussi servir à contenir et emballer des produits non alimentaires , et ses caissons peuvent contenir des produits anti-rouille, humidificateurs ou absorbeurs d'humidité, etc. The container of the invention can also be used to contain and package non-food products, and its boxes can contain anti-rust products, humidifiers or moisture absorbers, etc.
Le bac de l'invention peut aussi servir de réserve d'eau pour les bacs à fleurs. The tank of the invention can also serve as a water reserve for the flower boxes.
D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante d'un mode préféré de réalisation. I1 sera fait référence au dessin annexé sur lequel
- la figure 1 est une vue en perspective d'une plaque de polypropylène extrudé en caisson,
- la figure 2 est une vue en perspective de la plaque précédente après thermoformage et percement pour obtenir le bac de l'invention.Other characteristics and advantages of the invention will emerge from the following description of a preferred embodiment. I1 will be referred to the attached drawing on which
FIG. 1 is a perspective view of a plate of polypropylene extruded in a box,
- Figure 2 is a perspective view of the previous plate after thermoforming and drilling to obtain the tray of the invention.
- la figure 3 est une vue en perspective de la plaque de la figure 1 après pliage et incision pour obtenir un second mode de réalisation du bac de l'invention. - Figure 3 is a perspective view of the plate of Figure 1 after folding and incision to obtain a second embodiment of the tray of the invention.
- la figure 4 est une vue en coupe d'un bac montrant les pieds et les trous spécialement conformés. - Figure 4 is a sectional view of a tray showing the feet and specially shaped holes.
La plaque 1 de polypropylène est réalisée directement par extrusion de manière à posséder une surface supérieure 2 et une surface inférieure 3 séparées-par des bandes longitudinales 4 délimitant des couloirs ou caissons 5 d'une section sensiblement carrée de quelques millimètres de côté. The polypropylene plate 1 is produced directly by extrusion so as to have an upper surface 2 and a lower surface 3 separated by longitudinal strips 4 delimiting corridors or boxes 5 of a substantially square section of a few millimeters on a side.
Cette plaque 1 est ensuite thermoformée (fig.l) pour obtenir le bac 6, comportant un fond 7, des parois latérales 8, et un rebord 9. Le thermoformage doit être pratiqué avec soin de manière à permettre la déformation globale de la plaque 1 sur le bac 6, mais sans affaissement excessif des surfaces 2 et 3 l'une sur l'autre, notamment au niveau du fond 7, ce qui ferait disparaitre les caissons par écrasement à ce niveau. L'outil de thermoformage comprend par exemple un poinçon associé à un moule à empreinte aspirante. This plate 1 is then thermoformed (fig.l) to obtain the tray 6, comprising a bottom 7, side walls 8, and a flange 9. The thermoforming must be carried out with care so as to allow the overall deformation of the plate 1 on the tank 6, but without excessive sagging of the surfaces 2 and 3 one on the other, in particular at the bottom 7, which would make the boxes disappear by crushing at this level. The thermoforming tool comprises, for example, a punch associated with a mold with a suction imprint.
De préférence simultanément au thermoformage, on a pratiqué dans la surface supérieure des caissons des trous 10 faisant communiquer les caissons avec l'intérieur du bac. Preferably simultaneously with thermoforming, holes 10 were made in the upper surface of the boxes making the boxes communicate with the inside of the tank.
Ces trous, de petites dimensions, permettent aux liquides d'être drainés dans les caissons du bac. These small holes allow liquids to be drained into the boxes of the tank.
Les caissons jouent par ailleurs un rôle bénéfique pour la conservation du produit en ce sens qu'ils assurent une certaine isothermie de l'emballage grâce au matelas d'air qu'ils contiennent. The boxes also play a beneficial role for the conservation of the product in the sense that they ensure a certain isothermicity of the packaging thanks to the air mattress they contain.
I1 est possible de profiter du thermoformage pour former (fig.4) à la paroi inférieure du bac 6, au fond du bac, des protubérances formant des pieds 11 antidérapants. I1 is possible to take advantage of thermoforming to form (fig.4) on the bottom wall of the tank 6, at the bottom of the tank, protrusions forming non-slip feet 11.
Indépendamnent des pieds 11, ou en me temps, on peut prévoir de donner une forme spéciale aux trous 10 (fig.4), qu'on pourrait qualifier d'anti-retour. A cet effet, les trous 10 sont conformés de telle sorte que leur orifice 12 se trouve au sommet d'une saillie 13 pratiquée vers l'intérieur du fond. De cette manière, même si le fond, dont les caissons contiennent du liquide, est placé à l'envers, le liquide ne risque pas de repasser par les orifices 12. I1 restera dans les caissons qui, à cet effet, sont de préférence fermés à leurs deux extrémités naturellement ouvertes (par exemple par écrasement ou soudure ou par divers procédés). Independently of the feet 11, or at the same time, we can plan to give a special shape to the holes 10 (fig.4), which could be described as non-return. To this end, the holes 10 are shaped so that their orifice 12 is at the top of a projection 13 made towards the inside of the bottom. In this way, even if the bottom, the boxes of which contain liquid, is placed upside down, the liquid is not likely to pass through the orifices 12. It will remain in the boxes which, for this purpose, are preferably closed at their two naturally open ends (for example by crushing or welding or by various processes).
Selon le mode de réalisation représentée à la figure 3, le bac 6' est formé de la plaque 1 après pliage de ses extrémités, transversalement à la direction des caissons, de manière à former deux parois latérales 8' bloquant les caissons. According to the embodiment shown in Figure 3, the tray 6 'is formed of the plate 1 after folding its ends, transversely to the direction of the boxes, so as to form two side walls 8' blocking the boxes.
Les trous peuvent être analogues à ceux de la figure 2 où être formés par des incisions 10' pratiqués en lignes sur la paroi supérieure du fond 7', parallélement aux parois 8', ou perpendiculairement ou même obliquement. The holes can be similar to those of FIG. 2 where they are formed by incisions 10 'made in lines on the upper wall of the bottom 7', parallel to the walls 8 ', or perpendicularly or even obliquely.
Le bac de l'invention peut s'employer seul, ou servir de double fond pour une caisse. The container of the invention can be used alone, or serve as a double bottom for a box.
Pour exercer cette fonction d'égouttoir, on peut utiliser une simple plaque dont l'extrémité des cannelures ou alvéoles serait auparavant obstruée de toute manière possible (soudage, collage, etc.) ou directement formée dans l'une ou les parois de l'emballage intérieur (fond, couvercle, coté). To exercise this function of drainer, one can use a simple plate whose end of the grooves or alveoli would be previously obstructed in any possible way (welding, gluing, etc.) or directly formed in one or the walls of the inner packaging (bottom, lid, side).
