Abstract

Package. Improvements to packages in the form of bags made from a transparent film and formed of lateral walls 1-2 of generally rectangular shape and integral along three of their sides 3, 4, 5 and whose free sides form the opening 8 of the bag, at least one of the lateral walls 1-2 being cut out in order to form openings characterised in that the openings are formed by series of slits 7, the slits 7 of each series having the same length, being disposed parallel to each other and regularly spaced in order to form tongues 10 between them, free spaces 9 being produced between the said series 6, 6a and the said slits being inclined in such a way as to form, with the edges 3-5 of the bag adjacent to the opening, angles of 45 DEG .

Description

La présente invention concerne les emballages constitués par des sacs formés à partir d'un film transparent de matière plastique. The present invention relates to packages consisting of bags formed from a transparent plastic film.

L'invention vise des sacs destinés à contenir des fruits ou légumes frais. The invention relates to bags intended to contain fresh fruit or vegetables.

De tels sacs sont très utilisés et destinés à protéger des fruits ou légumes et également à être suspendus pour le transport ou la présentation desdits fruits ou légumes. Such bags are widely used and intended to protect fruits or vegetables and also to be suspended for the transport or the presentation of said fruits or vegetables.

Comme ces sacs sont étanches, il se forme à l'intérieur une légère condensation ce qui nuit à l'esthétique de la présentation, de plus de tels sacs accélèrent le processus de murissage. As these bags are waterproof, a slight condensation is formed inside which affects the aesthetics of the presentation, moreover such bags speed up the ripening process.

Pour remédier à ces inconvénients, on a pensé à pratiquer dans de tels sacs de simples trous mais ceuxci se sont avérés insuffisants. To overcome these drawbacks, it has been thought to use simple holes in such bags, but these have proved to be insufficient.

La technique antérieure connait également de tels sacs dont les parois latérales sont découpées de manière à réaliser des ouvertures comme les ajours formés dans un métal déployé, mais de tels sacs sont peu résistants. The prior art also knows such bags, the side walls of which are cut so as to produce openings such as the openings formed in an expanded metal, but such bags are not very resistant.

La présente invention a pour objet des perfectionnements aux sacs réalisés à partir d'un film transparent qui remédient aux inconvénients ci-dessus. The present invention relates to improvements to bags made from a transparent film which overcomes the above drawbacks.

Les perfectionnements, selon l'invention, s'appliquent à des sacs réalisés à partir d'un film transparent et formés de deux parois latérales de forme générale rectangulaire et solidaires par trois de leurs côtés et dont les côtés libres forment l'ouverture du sac, l'une au moins des parois latérales étant découpée pour former des ouvertures et sont caractérisés en ce que les ouvertures sont formées par des séries de fentes, les fentes de chaque série ayant la même longueur, étant disposées parallèlement et régulièrement espacées de manière à ménager des languettes entre elles, des espaces libres étant ménagés entre lesdites séries et lesdites fentes étant inclinées de manière à former avec les bords du sac adjacents à l'ouverture des angles de 450.  The improvements according to the invention apply to bags made from a transparent film and formed from two side walls of generally rectangular shape and joined by three of their sides and whose free sides form the opening of the bag , at least one of the side walls being cut to form openings and are characterized in that the openings are formed by series of slots, the slots of each series having the same length, being arranged in parallel and regularly spaced so as to providing tongues therebetween, free spaces being provided between said series and said slots being inclined so as to form with the edges of the bag adjacent to the opening of the angles of 450.

Grâce à cette disposition, lorsque le sac est rempli et suspendu, les languettes ont tendance, les unes à se plier vers l'intérieur du sac et les languettes adjacentes à celles-ci à se plier vers ltextérieur de sorte qu'il se forme sur la paroi latérale pourvue des fentes des sortes de cheminées assurant une bonne ventilation du produit.  Thanks to this arrangement, when the bag is filled and suspended, the tabs tend, some to bend towards the inside of the bag and the tabs adjacent to them to bend inwards so that it forms on the side wall provided with slots of sorts of chimneys ensuring good ventilation of the product.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels
La figure 1 est une vue en élévation d'un sac, selon l'invention,
La figure 2 montre en perspective un sac, selon l'invention en position d'utilisation.
The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which
FIG. 1 is an elevation view of a bag according to the invention,
Figure 2 shows in perspective a bag according to the invention in the use position.

Le sac représenté aux figures est réalisé à partir d'un film transparent et comprend deux parois latérales 1 et 2 fixées par trois de leurs côtés 3, 4 et 5, les côtés libres formant une ouverture 8 pour l'introduction des objets à ensacher, par exemple des fruits tels que des bananes. The bag shown in the figures is made from a transparent film and comprises two side walls 1 and 2 fixed by three of their sides 3, 4 and 5, the free sides forming an opening 8 for the introduction of the objects to be bagged, for example fruits such as bananas.

Dans chaque parois l et 2 sont découpées des fentes 7, ces fentes étant disposées par séries 6, 6a, 6b etc.. et des espaces 9 étant ménagés entre les séries. In each wall l and 2 are cut slots 7, these slots being arranged in series 6, 6a, 6b etc. and spaces 9 being provided between the series.

Les fentes 7 ont toutes la même longueur .et dans chaque série, 6, 6a, 6b etc.. elles ménagent entre elles des languettes 10. The slots 7 all have the same length. And in each series, 6, 6a, 6b, etc. they provide tabs 10 between them.

Les fentes 7 d'une série sont parallèles, régulièrement espacées et pratiquées pour former avec les côtés 3 et 5 des angles de 450.  The slots 7 of a series are parallel, regularly spaced and formed to form angles of 450 with the sides 3 and 5.

Toutes fentes 7 de toutes les séries sont inclinées dans le même sens. All slots 7 of all the series are inclined in the same direction.

Comme on le voit à la figure2 lorsque le sac contient un produit et qu'il est suspendu le poids du produit tend à déformer le sac de sorte qu'une languette 10 d'une série tend à se plier vers l'intérieur du sac tandis que la languette adjacente tend au contraire à se plier vers l'extérieur. On forme ainsi dans chaque série 6, 6a, 6b etc.. des sortes de cheminées qui permettent une bonne ventilation du produit et évitent un murissage prématuré.  As seen in Figure 2 when the bag contains a product and it is suspended the weight of the product tends to deform the bag so that a tab 10 of a series tends to bend towards the inside of the bag while on the contrary, the adjacent tongue tends to bend outwards. We thus form in each series 6, 6a, 6b etc. of the kind of chimneys which allow a good ventilation of the product and avoid a premature walling.

Bien entendu, l'invention n'est pas limité au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.  Of course, the invention is not limited to the embodiment which has just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
