Abstract

The plant pot (B), e.g. 30 cm in diameter by 30 cm deep, is produced by extrusion blow-moulding from a plastic material that is elastically deformable at least at ambient temperature and has a rim with out-turned lower concave (4a) and in-turned upper convex (4b) sections. The rim of the pot is fitted with a reinforcing ring (B), produced by injection moulding from a plastic material that is rigid at ambient temperature and is shaped to clip onto the edge of the rim's in-turned section by means of an outer collar (9) and inner lugs (7).

Description

L'invention est relative à un pot monoparoi en matière plastique à bord de préhension renforcé. Elle concerne plus particulièrement les pots obtenus par extrusion soufflage et présentant une paroi évasée avec un renflement externe de bordure ceinturant l'ouverture supérieure.The invention relates to a single-walled plastic pot with reinforced grip edge. It relates more particularly to pots obtained by blow molding and having a flared wall with a external bulge around the upper opening.

Lorsque la dimension du pot est importante et par exemple atteint une hauteur de 30 centimètres pour un diamètre d'ouverture de 30 centimètres, la quantité de terre végétale pouvant être contenue dans le pot représente une masse importante. Il en résulte que, lorsqu'il faut déplacer le pot, l'effort exercé manuellement sur le renflement de bordure peut entraíner la déformation du pot avec le risque de dépasser la limite élastique de sa matière constitutive et de provoquer une déformation permanente inesthétique.When the size of the pot is important and for example reached a height of 30 centimeters for an opening diameter of 30 centimeters, the quantity of topsoil that can be contained in the pot represents a significant mass. As a result, when the pot has to be moved, the force exerted manually on the border bulge can cause the deformation of the pot with the risk of exceeding the elastic limit of its constituent material and to cause an unsightly permanent deformation.

A cet inconvénient, s'ajoute celui résultant du mauvais contact entre la main humaine et le bord de l'ouverture qui, sans être tranchant, présente bien souvent des angles vifs blessants.To this disadvantage is added that resulting from poor contact between the human hand and the edge of the opening which, without being sharp, very often presents offensive sharp angles.

Dans certains pots à réserve d'eau, cet inconvénient est éliminé par la présence d'un second élément, lui-même en général en forme de pot, introduit dans l'enveloppe externe pour former une double paroi s'étendant du fond au sommet du pot et délimitant la réserve d'eau.In some water reserve pots, this drawback is eliminated by the presence of a second element, itself generally in the form of a pot, introduced into the outer envelope to form a double wall extending from bottom at the top of the pot and delimiting the water reserve.

Ce second élément donne de l'épaisseur à la partie supérieure du pot qui peut ainsi être saisi avec plus de prise et sans risque de blessure par des arêtes vives.This second element gives thickness to the upper part of the pot which can thus be grasped with more grip and without risk of injury by sharp edges.

En général, la liaison du bord du pot avec le bord du second élément est assurée par engagement d'une nervure de l'un des éléments dans une rainure de l'autre élément, cet engagement étant réalisé à chaud, ou à froid si le second élément comporte des moyens d'écartement élastique du bord de l'ouverture du pot.In general, the connection of the edge of the pot with the edge of the second element is ensured by engagement of a rib of one of the elements in a groove of the other element, this engagement being carried out hot, or at cold if the second element comprises means for elastic spacing of the edge of the jar opening.

A ce jour, il n'existe pas de moyens pour améliorer le contact et la prise du renflement de bordure d'un pot monoparoi, autres que de retourner vers l'intérieur la paroi du pot en fin d'extrusion soufflage. Cette technique de fabrication met en oeuvre des moules complexes dont l'amortissement intervient sur le coût de fabrication et ralentit les cadences.To date, there are no means to improve contact and grip the edge bulge of a single wall pot, other than turning inwards the wall of the pot at the end of blow molding. This technique of manufacturing uses complex molds whose amortization intervenes on the manufacturing cost and slows down the rates.

L'invention a pour objet de remédier à ces inconvénients en fournissant un pot monoparoi à bord de préhension renforcé.The object of the invention is to remedy these drawbacks by providing a single-walled pot with a reinforced gripping edge.

Pour cela, elle adapte le mode de liaison entre deux éléments qui est décrit dans le document U.S 3 847 494 mettant en oeuvre un premier élément en forme de pot et un second élément cylindrique s'engageant dans le premier et comportant, du bas vers le haut, des moyens d'écartement, élastique et temporaire de l'ouverture du premier élément, des moyens d'encliquetage complémentaires de ceux du pot et une collerette périphérique externe apte à venir en appui sur le bord du premier élément.For this, it adapts the mode of connection between two elements which is described in document U.S 3,847,494 implementing a first pot-shaped element and a second cylindrical element engaging in the first and comprising, from the bottom up, spacing means, elastic and temporary opening of the first element, means complementary to those of the pot and a peripheral flange external able to come to bear on the edge of the first element.

Dans le pot selon l'invention, le premier élément en forme de pot comporte une collerette interne saillant sensiblement radialement dans le pot et apte à recevoir l'appui d'une collerette du second élément, tandis que le second élément est constitué par un anneau dont la hauteur permet à son bord inférieur de prendre appui sur la face interne du renflement de bordure, quand les collerettes sont en contact et après encliquetage des moyens complémentaires d'encliquetage, pour former une ceinture de renforcement de ce renflement de bordure.In the pot according to the invention, the first element in the form of a pot has an internal collar projecting substantially radially in the pot and able to receive the support of a flange of the second element, while the second element is constituted by a ring whose height allows its edge lower to bear on the internal face of the border bulge, when the flanges are in contact and after snap-fastening of the means complementary latching, to form a reinforcement belt this border bulge.

Ainsi, en fin de réalisation par extrusion soufflage, et après découpage du bord de son ouverture pour enlever l'excédent de matière, le premier élément constituant le pot reçoit le second élément. En fin d'emmanchement, et alors même que la base du second élément vient en appui sur la face interne du renflement de bordure, les moyens d'encliquetage complémentaires des deux éléments s'encliquètent en formant un ensemble indémontable. Cet anneau donne de l'épaisseur au renflement de bordure en facilitant sa préhension manuelle et, lors de cette préhension, forme une sorte de ceinture résistante évitant toute déformation du renflement de bordure.Thus, at the end of production by blow molding, and after cutting the edge of its opening to remove excess material, the first element constituting the pot receives the second element. Finally fitting, and even as the base of the second element comes in support on the internal face of the border bulge, the latching means complementary of the two elements snap into a whole cannot be dismantled. This ring gives thickness to the bulge of border in facilitating its manual gripping and, during this gripping, forms a sort resistant belt preventing any deformation of the border bulge.

Dans une forme d'exécution préférée, la collerette externe du second élément en forme d'anneau est bordée par un retour coudé vers le bas lui donnant, en coupe, une forme de crochet, ce retour possédant une extrémité acérée dont seule l'arête peut venir en contact d'appui élastique sur la collerette du pot.In a preferred embodiment, the outer flange of the second ring-shaped element is bordered by a bent back down giving it, in section, a hook shape, this return having a sharp end of which only the edge can come into contact with elastic support on the collar of the pot.

Lors de l'introduction du second élément dans le pot, et plus précisément lors de l'encliquetage, ce retour coudé donne une élasticité facilitant cet encliquetage et garantissant, à la fin de celui-ci, le contact entre la collerette du second élément et la collerette du pot, c'est-à-dire améliorant la finition générale de ce pot.When introducing the second element into the pot, and more precisely when snapping in, this bent return gives elasticity facilitating this latching and guaranteeing, at the end of it, the contact between the collar of the second element and the collar of the pot, that is to say improving the general finish of this pot.

D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé.Other characteristics and advantages will emerge from the description which follows with reference to the attached schematic drawing.

Figures 1 et 2 sont des vues de côté en élévation avec coupe partielle, respectivement, du pot et du second élément, Figures 1 and 2 are side elevation views in section partial, respectively, of the pot and the second element,

Figure 3 est une vue partielle en perspective montrant, à échelle agrandie, un détail constructif du second élément,Figure 3 is a partial perspective view showing, to scale enlarged, a constructive detail of the second element,

Figure 4 est une vue de côté en élévation avec coupe partielle montrant les deux éléments lorsqu'ils sont assemblés,Figure 4 is a side view in elevation with partial section showing the two elements when assembled,

Figure 5 est une vue partielle en coupe montrant, à échelle agrandie, la collerette du second élément en forme d'anneau.Figure 5 is a partial sectional view showing, to scale enlarged, the collar of the second ring-shaped element.

Le pot, selon l'invention, est donc composé de deux éléments, à savoir un premier élément en forme de pot A et un second élément en forme d'anneau B.The pot, according to the invention, is therefore composed of two elements, to know a first pot-shaped element A and a second shaped element ring B.

Le premier élément A présente la forme générale d'un pot à fond plat 2 dont les bords évasés 3 sont munis d'un renflement de bordure 4 bordant l'ouverture 5 ménagée dans le pot. Le renflement 4 comporte, vu de l'extérieur, une partie concave inférieure 4a et une partie convexe supérieure 4b, cette dernière partie étant prolongée par une collerette interne 4c saillant sensiblement radialement vers l'intérieur du pot. Cet élément est réalisé par extrusion soufflage en matière plastique déformable élastiquement au moins à température ambiante, et par exemple en polychlorure de vinyle.The first element A has the general shape of a bottomed pot flat 2 whose flared edges 3 are provided with a border bulge 4 bordering the opening 5 made in the pot. The bulge 4 comprises, seen from the outside, a lower concave part 4a and an upper convex part 4b, this last part being extended by a protruding internal flange 4c substantially radially inward of the pot. This item is made by extrusion blow molding of elastically deformable plastic at least at room temperature, for example polyvinyl chloride.

La pièce obtenue par extrusion soufflage subit une opération d'usinage consistant à découper l'excédent de matière en formant l'ouverture 5. Cette opération étant réalisée avec positionnement du pot, les tolérances dimensionnelles de l'ouverture sont réduites, au même titre que ses tolérances de centrage par rapport au corps du pot.The part obtained by blow molding undergoes an operation machining consisting in cutting the excess material forming the opening 5. This operation being carried out with positioning of the pot, the tolerances dimensions of the opening are reduced, as are its tolerances centering with respect to the body of the pot.

Le second élément B est constitué par un anneau dont la hauteur H est déterminée pour que son bord inférieur 6 puisse venir en appui sur la face interne 4d de la partie 4a de la bordure.The second element B is constituted by a ring whose height H is determined so that its lower edge 6 can come to bear on the face internal 4d of part 4a of the border.

Dans la forme d'exécution représentée, cet anneau est tronconique en allant en se rétrécissant vers le bas, mais il est évident qu'il peut également être tubulaire à génératrices parallèles et être, de section cylindrique, rectangulaire, carrée et voire même polygonale.In the embodiment shown, this ring is frustoconical by going in narrowing down but it is obvious that it can also be tubular with parallel generators and be of cylindrical section, rectangular, square and even polygonal.

Cet anneau comporte en allant du bas vers le haut des moyens d'écartement 7, des moyens d'encliquetage 8 et une collerette périphérique externe 9.This ring comprises by going from the bottom to the top of the means spacer 7, latching means 8 and a peripheral flange external 9.

Les moyens d'écartement 7 sont constitués par des rampes verticales allant vers le haut en s'évasant vers l'extérieur du second élément. Comme montré figures 2 et 3, les rampes 7 sont regroupées par série, par exemple de quatre, renforcées par une nervure horizontale 10. Dans chaque série, les rampes sont espacées les unes des autres et chacune des séries est répartie angulairement avec un angle d'espacement constant sur la périphérie du second élément B. Chaque rampe 7 se termine par un redan 8 formant cran d'encliquetage. Ce cran est précédé par une pente d'engagement 8a dont l'utilité sera précisée plus loin.The spacing means 7 consist of ramps vertical going upwards widening towards the outside of the second element. As shown in Figures 2 and 3, the ramps 7 are grouped by series, by example of four, reinforced by a horizontal rib 10. In each series, the ramps are spaced from each other and each of the series is angularly distributed with a constant spacing angle on the periphery of the second element B. Each ramp 7 ends in a step 8 forming a notch latching. This notch is preceded by an engagement slope 8a of which the usefulness will be specified later.

Comme le montre plus en détails la figure 5, la collerette externe 9 du second élément B est bordée extérieurement par un retour 12 coudé vers le bas, à sensiblement 45° dans la forme d'exécution représentée. L'extrémité du retour 12 est acérée, c'est-à-dire présente une section transversale en forme de V dont seule l'arête 12a peut venir en contact avec la collerette 4c du premier élément, comme montré à la figure 5.As shown in more detail in FIG. 5, the external flange 9 of the second element B is bordered externally by a bent return 12 towards the low, at approximately 45 ° in the embodiment shown. The end of the back 12 is sharp, i.e. has a shaped cross section of V of which only the edge 12a can come into contact with the flange 4c of the first element, as shown in figure 5.

Ce second élément de renfort est réalisé par injection dans une matière plastique rigide à température ambiante, et par exemple, en polypropylène.This second reinforcing element is produced by injection into a rigid plastic at room temperature, for example, polypropylene.

Lorsque le pot A est réalisé avec son ouverture 5, le second élément de renfort B est engagé dans cette dernière jusqu'à ce que ses rampes 7 viennent en contact avec le bord de l'ouverture 5.When pot A is made with its opening 5, the second reinforcement element B is engaged in the latter until its ramps 7 come into contact with the edge of the opening 5.

En exerçant un effort vertical sur l'anneau B, les rampes 7 exercent sur l'ouverture 5, un effort d'écartement jusqu'à ce que la collerette 4c rencontre la rampe 8a et s'engage sous la collerette 9 en soulevant le retour coudé 12. Au même instant, le bord inférieur 6 de l'anneau vient en contact avec la face interne 4d du pot A.By exerting a vertical force on the ring B, the ramps 7 exert on the opening 5, a spacing force until the flange 4c meets the ramp 8a and engages under the flange 9 by lifting the return angled 12. At the same time, the lower edge 6 of the ring comes into contact with the inner face 4d of the pot A.

En fin d'engagement, le retour coudé 12 revient élastiquement à sa position initiale en assurant la parfaite finition de l'assemblage.At the end of engagement, the bent return 12 elastically returns to its initial position ensuring the perfect finish of the assembly.

Lorsque les deux éléments du pot sont assemblés, et comme montré figure 4, le second élément B forme une ceinture qui, non seulement, donne de l'épaisseur au renflement de bordure 4 en facilitant sa préhension manuelle, mais également renforce cette bordure. En effet, si l'effort de préhension tend à déplacer la bordure dans le sens de la flèche 11 de figure 4, la paroi tronconique du second élément en forme d'anneau B s'arc-boute sur la face 4d pour augmenter la rigidité de ce renflement, tandis que, si ce renflement de bordure est soumis à un effort dans le sens inverse de la flèche 11, c'est l'ensemble de l'anneau B qui forme un élément de rigidification s'opposant à la déformation vers l'extérieur du renflement.When the two elements of the pot are assembled, and as shown in Figure 4, the second element B forms a belt which not only gives thickness to the border bulge 4 by facilitating its gripping manual, but also reinforces this border. Indeed, if the effort of gripping tends to move the border in the direction of arrow 11 in FIG. 4, the frustoconical wall of the second ring-shaped element B arches on the face 4d to increase the rigidity of this bulge, while, if this border bulge is subjected to a force in the opposite direction to the arrow 11, it is the assembly of the ring B which forms a stiffening element opposing the outward deformation of the bulge.
