PROCEDE DE FABRICATION D'UN RECIPIENT MUNI D'ANSES DE
PORTAGE MONOBLOC ET RECIPIENT OBTENU PAR LEDIT PROCEDE.METHOD FOR MANUFACTURING A CONTAINER WITH HANDLES
MONOBLOCK CARRYING AND CONTAINER OBTAINED BY SAID METHOD.
La présente invention concerne un procédé de fabrication d'un récipient en matière plastique moulée muni d'anses de portage monobloc, ainsi que le récipient obtenu par ledit procédé.The present invention relates to a method of manufacturing a molded plastic container provided with one-piece carrying handles, as well as the container obtained by said method.
Elle s'applique plus particulièrement, mais non exclusivement, à la réalisation de clayettes servant à contenir des godets ou des pots dans lesquels sont habituellement vendues des plantes, par exemple des plantes à massif (plantes annuelles) et des plantes vivaces.It applies more particularly, but not exclusively, to the production of shelves used to contain pots or pots in which plants are usually sold, for example bedding plants (annual plants) and perennials.
Ces clayettes se présentent sous la forme d'un bac sensiblement parallélépipédique, allongé selon un axe longitudinal. Elles sont ouvertes dans le haut et présentent un fond ajouré, notamment pour laisser s'écouler l'eau d'arrosage des godets.These shelves are in the form of a substantially rectangular tank, elongated along a longitudinal axis. They are open at the top and have an openwork bottom, in particular for letting the water flow from the buckets.
Bien entendu, ces clayettes qui constituent en quelque sorte des emballages perdus, peu fréquemment réemployés par les utilisateurs, doivent être réalisées à des couts aussi faibles que possible : A cet effet, on utilise une matière plastique telle que, par exemple, du polypropylène, présentant après moulage des propriétés telles qutil devient possible de réduire au strict minimum la quantité de matière utilisée tout en obtenant une résistance mécanique suffisante.Of course, these shelves which constitute, in a way, lost packaging, not very often reused by users, must be produced at costs as low as possible: For this purpose, a plastic material is used such as, for example, polypropylene, having after molding properties such that it becomes possible to reduce the quantity of material used to a strict minimum while obtaining sufficient mechanical strength.
Il s'avère qu'une fois chargées de leurs godets, ces clayettes sont difficiles à manipuler : Leur portage exige l'emploi des deux mains disposées de manière à supporter le fond ajouré.It turns out that once loaded with their buckets, these shelves are difficult to handle: Carrying requires the use of two hands arranged to support the perforated bottom.
Il est clair que dans cette position, les mains de l'utilisateur risquent d'être souillées par l'eau sale chargée qui s'écoule des godets.It is clear that in this position, the user's hands may be contaminated by the dirty dirty water flowing from the buckets.
Pour éviter ces inconvénients, on a proposé d'utiliser des anses réalisées séparément. Toutefois, cette solution n'est pas satisfaisante notamment du fait que les anses sont coûteuses, difficiles à fixer, et sont stockées séparément des clayettes.To avoid these drawbacks, it has been proposed to use handles produced separately. However, this solution is not satisfactory in particular because the handles are expensive, difficult to fix, and are stored separately from the shelves.
L'invention a donc plus particulièrement pour but de supprimer ces inconvénients grâce à une clayette à anses incorporées, obtenue en une seule opération de moulage, à l'aide d'un moule de conception simple, et ce, sans augmentation sensible du prix de revient et en conservant la possibilité d'un stockage par emboîtement des clayettes les unes dans les autres.The invention therefore more particularly aims to eliminate these drawbacks by means of a shelf with incorporated handles, obtained in a single molding operation, using a mold of simple design, without significant increase in the price of returns and retaining the possibility of storage by nesting the shelves in one another.
A cet effet, l'invention tire avantageusement parti - de la forme spécifique des clayettes (parallélépipède
allongé), - de la technique de fabrication des clayettes (moulage
avec ouverture du moule par le haut), et - des propriétés mécaniques de la matière plastique uti
lisée (possibilité de torsion).To this end, the invention advantageously takes advantage of - the specific shape of the shelves (parallelepiped
elongated), - the technique of making the shelves (molding
with mold opening from above), and - mechanical properties of the plastic used
edged (possibility of twisting).
Elle parvient aux résultats précités grâce à un procédé consistant à prévoir dans le moule servant à la réalisation des récipients, une empreinte périphérique entourant la bordure supérieure de la cavité de moulage des récipients et communiquant avec celle-ci grâce à au moins deux passages situés en deux emplacements opposés respectivement situés au centre des deux bords longitudinaux de ladite bordure.It achieves the abovementioned results by means of a process consisting in providing in the mold serving for the production of the containers, a peripheral imprint surrounding the upper edge of the mold cavity for the containers and communicating with it by means of at least two passages located at two opposite locations respectively located in the center of the two longitudinal edges of said border.
Cette empreinte périphérique permet donc d'obtenir, après moulage du récipient, deux arceaux solidarisés au récipient par leurs extrémités par les deux pattes de fixation obtenues au niveau des susdits passages du moule.This peripheral imprint therefore makes it possible to obtain, after molding the container, two arches secured to the container by their ends by the two fixing lugs obtained at the above-mentioned mold passages.
Ces arceaux peuvent être ensuite rabattus de manière à amener leurs parties centrales au contact l'une de l'autre pour obtenir une anse de portage dont la poignée est constituée par les deux parties centrales.These arches can then be folded down so as to bring their central parts into contact with one another to obtain a carrying handle whose handle is formed by the two central parts.
Un mode d'exécution de l'invention sera décrit ci-après, à titre d'exemple non limitatif, avec référence aux dessins annexés dans lesquels
La figure 1 est une vue en perspective schéma
tique d'une clayette obtenue à l'issue de la
phase de moulage du procédé selon l'invention
La figure 2 est une vue similaire à celle de la
figure 1 mais en position rabattue des
arceaux ;
La figure 3 est une vue partielle du moule
permettant d'obtenir la clayette
La figure 4 est une coupe schématique permet
tant d'illustrer le principe d'un mode
d'assemblage des parties centrales des arceaux.An embodiment of the invention will be described below, by way of non-limiting example, with reference to the accompanying drawings in which
Figure 1 is a perspective view diagram

molding phase of the process according to the invention
Figure 2 is a view similar to that of
Figure 1 but in the folded position of

Figure 4 is a schematic section allows
so many illustrate the principle of a mode
assembly of the central parts of the arches.
La clayette 1 représentée sur ces figures, présente sensiblement la forme d'un parallélépipède allongé selon un axe longitudinal. Bien entendu, les faces latérales 2 à 5 de cette clayette présentent une légère dépouille pour permettre le démoulage.The shelf 1 shown in these figures has substantially the shape of a parallelepiped elongated along a longitudinal axis. Of course, the side faces 2 to 5 of this shelf have a slight draft to allow demolding.
Cette clayette 1 présente un fond ajouré 6 et, du côté opposé à ce fond, une face supérieure présentant une ouverture rectangulaire bordée par un léger rebord périphérique 7.This shelf 1 has an openwork bottom 6 and, on the side opposite this bottom, an upper face having a rectangular opening bordered by a slight peripheral rim 7.
Selon l'invention, cette clayette 1 comprend, en outre, venu de moulage, sensiblement dans le plan de la face supérieure, un cerclage périphérique 8 qui s'étend parallèlement au rebord 7 et à une faible distance de celuici.According to the invention, this shelf 1 further comprises, coming from molding, substantially in the plane of the upper face, a peripheral hoop 8 which extends parallel to the rim 7 and at a short distance from it.
Ce cerclage 8 est solidarisé au rebord 7 grâce à des pattes de fixation 9, également venues de moulage, situées en deux emplacements opposés, au centre des deux parties longitudinales du rebord 7.This strapping 8 is secured to the rim 7 by means of fixing lugs 9, also coming from molding, located in two opposite locations, at the center of the two longitudinal parts of the rim 7.
Ce cerclage 8, qui présente ici une section en cornière, peut être obtenu en prévoyant entre les deux parties 11, 12 du moule qui sert à obtenir la clayette 1 une empreinte 13 de forme correspondante. Il est clair que cette adjonction n' entraîne pas de complication notable du moule ni un surcoût important de ce dernier.This strapping 8, which here has an angle section, can be obtained by providing between the two parts 11, 12 of the mold which serves to obtain the shelf 1 an imprint 13 of corresponding shape. It is clear that this addition does not involve any noticeable complication of the mold nor a significant additional cost of the latter.
Les deux arceaux 8', 8" constitués par le cerclage 8, de part et d'autre des pattes de fixation 9, sont destinés à être rabattus de manière à ce que leurs éléments transversaux viennent s'appliquer l'un contre l'autre, sensiblement dans le plan transversal de symétrie de la clayette 1, et ce, de manière à constituer la poignée de l'anse telle que celle représentée sur la figure 2.The two arches 8 ′, 8 ″ constituted by the strapping 8, on either side of the fixing lugs 9, are intended to be folded down so that their transverse elements are applied one against the other , substantially in the transverse plane of symmetry of the shelf 1, so as to constitute the handle of the handle such as that shown in FIG. 2.
La fixation des éléments transversaux des arceaux 8' et 8" peut alors être assurée par des moyens de clipsage pouvant faire intervenir, comme représenté sur la figure 4, un téton à tête conique 15 prévu dans l'un des élé ments, qui vient s'engager dans un perçage en étoile 16 prévu dans l'autre élément et qui présente un diamètre central inférieur à celui de la tête 15.The fixing of the transverse elements of the arches 8 ′ and 8 "can then be ensured by clipping means which can involve, as shown in FIG. 4, a conical head stud 15 provided in one of the elements, which comes s 'Engage in a star bore 16 provided in the other element and which has a central diameter smaller than that of the head 15.
Bien entendu, pour faciliter le rabattement des arceaux, il sera possible de prévoir des lignes de pliage L amincies au niveau des raccordements entre les éléments longitudinaux des arceaux 8', 8", les pattes de fixation 9 et, éventuellement, les éléments transversaux des arceaux 8', 8".Of course, to facilitate the folding of the hoops, it will be possible to provide folded fold lines L at the connections between the longitudinal elements of the hoops 8 ′, 8 ", the fixing lugs 9 and, possibly, the transverse elements of the 8 ', 8 "arches.
Avantageusement, la matière plastique utilisée pour réaliser la clayette 1 consistera en du polypropylène.Advantageously, the plastic material used to make the shelf 1 will consist of polypropylene.
Cette matière supporte en effet de nombreux pliages sans se détériorer. This material supports many folds without deteriorating.
