Abstract

A double walled container has an outer wall made of resin coated fabric enclosing a smaller plastic sheet that ensures the container is fluid tight. An Independent claim is included for the manufacture of a container as above by coating a fabric onto a surface, covering it with the plastic sheet, placing a removable core on the sheet and then folding the fabric to enclose the sheet. Preferred Features: The plastic of the sheet becomes embedded in the fabric. The resin coated fabric does not contact the container contents.

Description

La présente invention se rapporte à des vases de différentes formes à double paroi de matières synthétiques ainsi que son procédé de fabrication.The present invention relates to vases of different double-walled shapes of synthetic materials as well as its manufacturing process.

On a déjà proposé et utilisé en pratique, dans le passé, divers types de vases à double paroi dont la paroi est composée de tissus, résiné ou non.Various types of double-walled vases have been proposed and used in practice in the past, the wall of which is made of fabrics, resinated or not.

Les vases à double paroi de la technique antérieure ont été fabriqué jusqu'à présent autour d'un récipient en verre ou en terre cuite, le récipient intérieur assurant la forme définitive du vase mais augmentant les coûts de matières premières, de transport et de fragilité. On peut ou on a proposé et utilisé en pratique un récipient ou contenant composé uniquement de tissu enduit de résine, l'inconvénient réside dans le contact entre toutes matières organiques destinées ou non à la consommation et la résine appliquée sur le tissu, les résines 100% alimentaires et résistantes à l'eau sont très onéreuses, d'où un surcoût de matières premières.The double-walled vases of the prior art have so far been manufactured around a glass or terracotta container, the inner container ensuring the final shape of the vase but increasing the costs of raw materials, transport and fragility . It is possible or has been proposed and used in practice a container or container composed solely of fabric coated with resin, the drawback lies in the contact between any organic material intended or not for consumption and the resin applied to the fabric, the resins 100 % food and water resistant are very expensive, hence an additional cost of raw materials.

Par conséquent, la présente invention a, notamment, pour but :
s de réaliser un récipient à double paroi dont la paroi intérieure assure l'étanchéité en épousant les formes de la paroi extérieure
in de réaliser un récipient à double paroi qui est moins onéreux que
les récipient connus
de construire un récipient à double paroi original par sa
réalisation et sa qualité esthétique
de construire un récipient à double paroi sans limitation de
formes, celles-ci étant conditionnées par celle du noyau intérieur
de proposer un procédé de fabrication d'un récipient à double
paroi comportant un noyau de modelage amovible
La présente invention se rapporte à des vases de différentes formes à double paroi comprenant en extérieur un tissu rigidifié par de la résine et une paroi intérieur la mme forme que la paroi extérieure mais de dimension plus petite et dont au moins la paroi latérale est fixée dans la paroi latérale formée par le tissu La paroi intérieure assurant l'étanchéité et le non contact de toutes matières contenues dans ce récipient avec le tissu.
Consequently, the aim of the present invention is, in particular:
s to produce a double-walled container, the inner wall of which seals by matching the shapes of the outer wall
in to make a double-walled container which is less expensive than
known containers
to build an original double-walled container by its
realization and its aesthetic quality
to build a double-walled container without limitation of
forms, these being conditioned by that of the inner core
to propose a method of manufacturing a double container
wall with a removable modeling core
The present invention relates to vases of different double-walled shapes comprising on the outside a fabric stiffened by resin and an inner wall the same shape as the outer wall but of smaller dimension and of which at least the side wall is fixed in the side wall formed by the fabric The interior wall ensuring the tightness and the non-contact of all materials contained in this container with the fabric.

La présente invention a également pour objet un procédé de fabrication de tels vases à double paroi dans lequel un tissu préalablement enduit de résine est posé sur une surface plate puis recouvert par une feuille de matière plastique étanche de dimensions plus petites, un noyau amovible est ensuite posé en son centre et le tissu est préalablement enduit de résine et la teille de matière plastique étanche sont formés autour de ce noyau pour en prendre la forme, des liens de serrage emprisonnant le tissu autour du noyau. Le tissu durci, la feuille de matière plastique étanche se retrouve prise dans ses plis et devient solidaire de l'ensemble, on retire le noyau et on obtient un vase dur et étanche limitant les coûts de fabrication et de transport.The present invention also relates to a method of manufacturing such double-walled vases in which a fabric previously coated with resin is placed on a flat surface and then covered by a sheet of waterproof plastic material of smaller dimensions, a removable core is then placed in its center and the fabric is previously coated with resin and the seal of waterproof plastic is formed around this core to take its shape, tightening ties trapping the fabric around the core. The hardened fabric, the waterproof plastic sheet is caught in its folds and becomes integral with the assembly, the core is removed and a hard, waterproof vase is obtained, limiting the manufacturing and transport costs.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, donnée à titre d'exemple non limitatif et en regard des dessins annexés, sur :
La figure 1 est une vue du dessus représentant la disposition et l'ordre chronologique à appliquer pour la réalisation d'un contenant à double paroi ou (1) le tissu préalablement imprégné de résine est recouvert par (2) une pellicule de matière plastique de plus petites dimensions et ou (3) le noyau est posé en leur centre (1) (2) et maintenu par (4) un axe de maintient
La figure 2 est une vue de coté des éléments (1) (2) (3) (4) de la figure 1 accompagné d'une surface plate (A) de plus grande dimension que la feuille de tissus résinée (1) permettant le maintien d'une potence (B) ou est fixé une planche de maintien (C) sous laquelle l'axe de maintien (4) du noyau amovible (3) se fixe. Des pinces (D) destinées à retenir le tissu y sont également fixées
