Abstract

A clip design for joining two panels of rigid thermoplastic material (I) comprises a combination of at thin-walled pocket in one panel and a stud on the other panel where the stud has projecting fins which locally deform the pocket to obtain a firm engagement. Suitable for fastening the lid of a plastic box to its base, e.g. for an egg pack of PVC with a wall thickness of 0.3-0.6 mm. Text characterises (I) by an elastic modulus of at least 60 000 N/sq. cm. Pref. the thin walled zone has a thickness less than 65% of that of the base panel, and adjacent zones retain at least 95% of their original thickness. To assist opening, each panel is shaped to expose one web for ease of manual grip adjacent to the clip. Opt. the pocket has no base, so that the head of the stud can be pressed out to release the clip.

Description

Assemblage dissociable de deux feuilles en inatiere thernioplastique rigide
La présente invention a pour objet un assemblage dissociable de deux feuilles en matière thermoplastique rigide, du type dans lequel un téton, solidaire d'une des feuilles est engage et coince de manière amovible dans un logement solidaire de l'autre feuille
Des assemblages de ce type ont deja ete proposes pour des bottes legeres constituees de deux feuilles en matière thermoplastique rigide, qui SOut superposees et conformees en sorte qu'elles forment respectivement le fond et le couvercle de la botte.Separable assembly of two sheets in rigid thernioplastic material
The present invention relates to a separable assembly of two sheets of rigid thermoplastic material, of the type in which a stud, integral with one of the sheets is engaged and removably wedges in a housing integral with the other sheet
Assemblies of this type have already been proposed for light boots consisting of two sheets of rigid thermoplastic material, which are superimposed and conform so that they respectively form the bottom and the cover of the boot.

Ces bottas légers sont habituellement destines a servir d'emballage protecteur pour des matières fragiles, telles que, par exemple, des oeufs, des fruits ou des articles de patisserie. These light bottas are usually intended to serve as protective packaging for fragile materials, such as, for example, eggs, fruit or baked goods.

A cet effet, l'assemblage du couvercle sur le fond doit respecter une serie de conditions imperatives. Il doit notamment etre capable de maintenir le couvercle dans une position fixe et précise sur le fond, pour conférer une rigidité suffisante à la botte en position fermee. Il doit aussi être suffisamment résistant pour s opposer à une separation intempestive du fond du couvercle pendant la manutention de la botte, mais il doit par ailleurs être simple et robuste pour que les utilisateurs de la botte puissent ouvrir ou refermer celle-ci aisement et a volonté, en dissociant le couvercle du fond ou en les associant à nouveau l'un à l'autre. L'assemblage doit en outre etre de conception simple, dont la fabrication soit bon marché.For this purpose, the assembly of the cover on the bottom must respect a series of imperative conditions. In particular, it must be able to hold the cover in a fixed and precise position on the bottom, to give sufficient rigidity to the boot in the closed position. It must also be strong enough to prevent untimely separation of the bottom of the cover during handling of the boot, but it must also be simple and robust so that users of the boot can open or close it easily and will, by dissociating the cover from the bottom or by associating them again one with the other. The assembly must also be of simple design, the manufacture of which is inexpensive.

Dans le brevet britannique t 245 596 déposé le 19 septembre 1968 au nom de I.S.A.P. S.p.a., on propose un mode d'exécution particulier d'un assemblage dissociable de deux feuilles en ratière thermoplas- tique rigide, conformées en sorte de orner respectivement le fond et le couvercle d'une botte. In British patent t 245,596 filed September 19, 1968 in the name of I.S.A.P. S.p.a., a particular embodiment is proposed of a separable assembly of two sheets in rigid thermoplastic dobby, shaped so as to adorn the bottom and the cover of a boot respectively.

Dans cet assemblage connu, les deux feuilles présentent chacune un ressaut tronconique, les deux ressauts étant dirigés l'un vers l'autre lorsque les feuilles sont assemblées. In this known assembly, the two sheets each have a frustoconical projection, the two projections being directed towards each other when the sheets are assembled.

Le ressaut de la feuille constituant le fond de la botte a sa paroi latérale qui est repliée en creux vers l'intérieur du ressaut; de manière à former dans celui-ci un loement tronconique. The projection of the sheet constituting the bottom of the boot has its side wall which is folded inward towards the interior of the projection; so as to form therein a frustoconical housing.

Le ressaut de la feuille conetiruant le couvercle de la botte 2 la forse d'un téton tronconique, conçu pour autre engagé dans le logement susdit lorsque les feuilles sont assemblées. Le téton comprend une paire de saillies latérales, qui sont destinées a entre pincées par la paroi latérale du logement formé dans l'autre ressauts
Cet assemblage connu prEseate le désavantage de manquer de rigidité, da fait que la retenue du téton dans le logement est assurer essentiellement par la paroi latérale amincie du logement dont la résistance a la flexion est faible. Ce désavantage est particulierement significatif dans le cas d'une botte, car il en résulte un risque accru que le contenu de celle-ci soit détérioré en cours de manipulation.The projection of the sheet conetiruant the cover of the boot 2 the formation of a frustoconical nipple, designed for another engaged in the aforementioned housing when the sheets are assembled. The nipple includes a pair of lateral projections, which are intended to be pinched between the lateral wall of the housing formed in the other projections
This known assembly prEseate the disadvantage of lacking rigidity, da that the retention of the stud in the housing is provided essentially by the thinned side wall of the housing whose flexural strength is low. This disadvantage is particularly significant in the case of a boot, since it results in an increased risk that the contents thereof will be damaged during handling.

Un désavantage supplémentaire de cet assemblage connu réside dans la configuration compliquée du ressaut comprenant le logement. An additional disadvantage of this known assembly lies in the complicated configuration of the projection comprising the housing.

dont la réalisation par déformation plastique de la feuille en matière thermoplastique rigide est de ce fait difficile.whose production by plastic deformation of the sheet of rigid thermoplastic material is therefore difficult.

De part sa configuration, ce ressaut est par ailleurs fragile, et se paroi risque facilement d'être plissée ou déchirée au cas où le téton ne serait pas engagé avec précision dans le logement.  Due to its configuration, this projection is moreover fragile, and is easily walled and may be folded or torn if the stud is not precisely engaged in the housing.

L'invention a pour objectif de remédier aux inconvénients précités, en fournissant un assemblage dissociable de deux feuilles en matière thermoplastique rigide l'une sur l'autre, qui présente une rigidité élevée et qui soit résistant, robuste et de conception simple. The invention aims to remedy the aforementioned drawbacks, by providing a separable assembly of two sheets of rigid thermoplastic material one on the other, which has a high rigidity and which is resistant, robust and of simple design.

L'invention concerne des lors un assemblage dissociable de deux feuilles en matiere thermoplastique rigide, l'une sur l'autre, la premiere feuille comprenant au moins un logement obtenu par déformation plastique de la feuille et la seconde feuille comprenant au moins un téton qui est obtenu par déformation plastique de la feuille, qui présente une saillie latérale et qui est agencé en sorte d'être engagé dans le logement; selon l'invention, le logement est formé de telle sorte que la première feuille présente une zone non amincie, calée entre la saillie et la seconde feuille. The invention therefore relates to a separable assembly of two sheets of rigid thermoplastic material, one on top of the other, the first sheet comprising at least one housing obtained by plastic deformation of the sheet and the second sheet comprising at least one stud which is obtained by plastic deformation of the sheet, which has a lateral projection and which is arranged so as to be engaged in the housing; according to the invention, the housing is formed so that the first sheet has an unthinned zone, wedged between the projection and the second sheet.

Dans l'assemblage selon l'invention, on entend désigner, par matière thermoplastique rigide, une matiere thermoplastique possédant un module d'élasticité supérieur à 60.000 /cl2, de préférence au moins égal a" 68.500 N/cm2 (Dictionnaire Technique des Matières Plastiques, A.M.Wittfoht, Carl Hanser Verlag, 1966,
Tome 3, p.370).In the assembly according to the invention, the term “rigid thermoplastic material” is intended to denote a thermoplastic material having a modulus of elasticity greater than 60,000 / cl2, preferably at least equal to "68,500 N / cm2 (Technical Dictionary of Plastics , AMWittfoht, Carl Hanser Verlag, 1966,
Volume 3, p.370).

Le choix de la matière thermoplastique et de l'épaisseur des feuilles dépend de la destination de l'assemblage; le choix optimum peut être aisément déterminé dans chaque cas particulier par l'utilisateur. The choice of the thermoplastic material and the thickness of the sheets depends on the destination of the assembly; the optimum choice can be easily determined in each particular case by the user.

Par exemple, dans le cas de feuilles conformées de manière à constituer respectivement le fond et le couvercle d'une botte légère pour l'emballage de produits fragiles tels que des oeufs, on peut avantageusement faire usage d'une matière thermoplastique transparente, à base de polychlorure de vinyle, dont ltepaisseur est sensiblement comprise entre 0,3 et 0,6 mm. For example, in the case of sheets shaped so as to respectively constitute the bottom and the cover of a light boot for packaging fragile products such as eggs, it is advantageous to use a transparent thermoplastic material, based polyvinyl chloride, the thickness of which is substantially between 0.3 and 0.6 mm.

Le téton et le logement sont obtenus par déformation plastique des feuilles. Celle-ci peut être un formage à froid où un thermoformage et elle peut être réalisée par exemple par emboutissage de la matiere où, de préférence, par étirage par soufflage ou sous vide.  The nipple and the housing are obtained by plastic deformation of the sheets. This can be cold forming or thermoforming and it can be carried out, for example, by stamping the material or, preferably, by stretching by blowing or under vacuum.

Le téton a de préférence une forme cylindrique ou tronconique, de section circulaire, ovale, carrée ou rectangulaire. The stud preferably has a cylindrical or frustoconical shape, of circular, oval, square or rectangular section.

La saillie latérale du téton a pour fonction de retenir le téton coincé dans le logement. Elle doit être conformée de manière a" pouvoir s'effacer provisoirement par déformation élastique du téton, pendant qu'on insère celui-ci dans le logement on l'en extrait. Elle peut par exemple consister en une aspérité locale protubérante de la paroi latérale du téton. The lateral projection of the nipple has the function of retaining the nipple stuck in the housing. It must be shaped so as to "be able to be temporarily removed by elastic deformation of the nipple, while the latter is inserted into the housing and extracted therefrom. It may for example consist of a protruding local asperity of the side wall nipple.

Selon l'invention, le logement est conçu de telle sorte que, lorsque le téton s'y trouve engagé, la première feuille, qui comprend ledit logement, présente une zone non amincie, qui est coincée entre la saillie du téton et la seconde feuille. According to the invention, the housing is designed so that, when the nipple is engaged therein, the first sheet, which comprises said housing, has an unthinned area, which is wedged between the projection of the nipple and the second sheet .

On entend désigner par zone non amincie de la première feuille, une zone de celle-ci dont l'épaisseur n'a pas diminué de plus de 10 Z par rapport l'épaisseur qu'elle avait avant la formation du logement. On choisit avantageusement une zone non amincie, dont l'épaisseur est au moins égale à 95 %, et de préférence à 98 Z, de l'épaisseur que la feuille possédait avant qu'elle ait été déformée plastiquement pour former le logement. The term “unthinned area” of the first sheet is intended to denote an area of the first sheet, the thickness of which has not decreased by more than 10% compared to the thickness it had before the formation of the housing. An unthinned zone is advantageously chosen, the thickness of which is at least equal to 95%, and preferably 98%, of the thickness that the sheet had before it was plastically deformed to form the housing.

La déformation plastique de la première feuille dans la zone de formation du logement doit par ailleurs être réglée de manière à provoquer un amincissement prononcé des parois du logement, pour les rendre aisément déformables élastiquement. The plastic deformation of the first sheet in the area of formation of the housing must also be adjusted so as to cause a pronounced thinning of the walls of the housing, to make them easily elastically deformable.

En règle générale, il est souhaitable de régler la déformation plastique de la première feuille pour que l'épaisseur des parois du logement soit au maximum égale 75 % de celle de la zone non amincie, et de préférence inférieure à 65 % de celle-ci. On obtient généralement de bons résultats lorsque l'épaisseur des parois du logement est comprise entre 10 et 60 % de celle de la zone non amincie, et plus spécialement entre 20 et 50 % de celle-ci. As a general rule, it is desirable to adjust the plastic deformation of the first sheet so that the thickness of the walls of the housing is at most equal to 75% of that of the unthinned zone, and preferably less than 65% thereof. . Generally, good results are obtained when the thickness of the walls of the housing is between 10 and 60% of that of the unthinned zone, and more especially between 20 and 50% thereof.

Dans l'assemblage selon l'invention, le logement est des lors délimité par une paroi latérale et éventuellement une paroi de fond, qui sont beaucoup plus minces, et donc beaucoup plus déformables élastiquement, que la zone non amincie précitée de la première feuille, et son ouverture est située dans cette zone non amincie.  In the assembly according to the invention, the housing is therefore delimited by a side wall and possibly a bottom wall, which are much thinner, and therefore much more elastically deformable, than the aforementioned unthinned zone of the first sheet, and its opening is located in this unthinned area.

Dans l'assemblage selon l'invention, la saillie du téton, qui est engagée dans le logement de la première feuille, déforme la paroi latéral mince du logement et prend appui sur la zone non amincie de la premiere feuille; il assure de la sorte une résistance efficace et calibrée à la dissociation des deux feuilles. In the assembly according to the invention, the projection of the stud, which is engaged in the housing of the first sheet, deforms the thin lateral wall of the housing and is supported on the unthinned area of the first sheet; it thus ensures an effective and calibrated resistance to the dissociation of the two sheets.

La zone non amincie de la première feuille oppose par ailleurs une résistance excessivement élevée à un déplacement latéral du téton et, par conséquent, à un glissement des feuilles l'une sur l'autre. The unthinned zone of the first sheet also opposes an excessively high resistance to a lateral displacement of the nipple and, consequently, to a sliding of the sheets one over the other.

Cette caractéristique de l'invention est particulièrement avantageuse dans le cas où les deux feuilles constituent respecti vement le fond et le couvercle d'une botte, car elle est de nature à conférer une rigidité élevée a la botte. This characteristic of the invention is particularly advantageous in the case where the two sheets respectively constitute the bottom and the cover of a boot, since it is capable of imparting high rigidity to the boot.

Dans une forme de réalisation préférée de l'invention, le téton présente deux saillies qui sont diamétralement opposées, et qui sont écartées l'une de l'autre d'une distance supérieure au diametre correspondant de l'ouverture du logement dans la zone non amincie de la premier feuille. In a preferred embodiment of the invention, the stud has two protrusions which are diametrically opposite, and which are spaced from each other by a distance greater than the corresponding diameter of the opening of the housing in the area not thinned out of the first leaf.

Cette rorme de réalisation de l'invention présente l'avantage de renforcer la résistance de ltassemblage à une dissociation des deux feuilles. This form of embodiment of the invention has the advantage of reinforcing the resistance of the assembly to dissociation of the two sheets.

Selon une autre forme de réalisation de l'inventlon, qui est particulirement aantgeuse, les feuilles présentent chacune une patte de préhension au voisinage du téton, respectivement du logement, les deux pattes étant disposees respectivement de part et d'autre du téton engagé dans le logement. According to another embodiment of the inventlon, which is particularly aantgeuse, the sheets each have a gripping tab in the vicinity of the stud, respectively of the housing, the two tabs being disposed respectively on either side of the stud engaged in the housing.

Cette forme de réalisation de l'invention est de nature à faciliter grandement l'extraction du téton hors du logement, lorsqu'on souhaite dissocier les deux feuilles. This embodiment of the invention is likely to greatly facilitate the extraction of the stud from the housing, when it is desired to dissociate the two sheets.

Selon une variante préférée de cette forme de réalisation de l'invention, chaque feuille présente une échancrure en regard de la patte de préhension de l'autre feuille. According to a preferred variant of this embodiment of the invention, each sheet has a notch opposite the gripping tab of the other sheet.

Cette variante de l'invention apporte l'avantage supplémentaire de permettre une diminution de l'encombrement de l'assemblage, sans nuire à la facilité d'accès aux pattes de préhension.  This variant of the invention provides the additional advantage of allowing a reduction in the size of the assembly, without affecting the ease of access to the gripping tabs.

Des particularités et détails de l'invention ressortiront de la description suivante des dessins annexes, qui représentent schématiquement une forme de réalisation préférée de l'assemblage selon l'invention. Special features and details of the invention will emerge from the following description of the accompanying drawings, which schematically represent a preferred embodiment of the assembly according to the invention.

Le long d'une zone marginale 4, respectivement 5, opposée la charniere 3, les fouilles 1 et 2 sont profilées en sorte qu on puisse, à volonté, les associer l'une à l'autre ou les dissocier l'une de l'autre, pour ouvrir ou fermer la botte. Along a marginal zone 4, respectively 5, opposite the hinge 3, the excavations 1 and 2 are profiled so that one can, as desired, associate them with one another or dissociate them from one other, to open or close the boot.

A cet effet, la feuille 1 présente, dans sa zone marginale 4, un logement 6 qui a été obtenu par déformation plastique d'une partie de la zone 4, par exemple par thermoformage sous vide. Le logement 6 est profilé en sorte de présenter une paroi cylindrique 7 s'étendant vers le haut à partir de la zone marginale 4 et une paroi de fond 8.  To this end, the sheet 1 has, in its marginal zone 4, a housing 6 which has been obtained by plastic deformation of part of the zone 4, for example by vacuum thermoforming. The housing 6 is profiled so as to present a cylindrical wall 7 extending upwards from the marginal zone 4 and a bottom wall 8.

Les parois 7 et 8 du logement présentent une épaisseur beaucoup plus faible que la zone marginale 4 qui lui est contiguë et qui constitue la zone non amincie précitée de la feuille 1. The walls 7 and 8 of the housing have a much smaller thickness than the marginal zone 4 which is contiguous to it and which constitutes the abovementioned unthinned zone of the sheet 1.

Par exemple, 11 épaisseur des parois 7 et 8 est égale approximativement à 30 % d l'épaisseur de la zone non amincie 4, et celle-ci a une épaisseur au moins égale à 97 % de celle qu'elle possédait avant la formation du logement.For example, the thickness of the walls 7 and 8 is approximately 30% of the thickness of the unthinned zone 4, and this has a thickness at least equal to 97% of that which it had before the formation of the housing.

La feuille 2 comprend, dans sa zone marginale 5, un téton 9 dirigé vers le haut, en regard du logement 6. Le téton 9 est obtenu par déformation plastique d'une partie de la zone marginale 5, par exemple par thermoformage sous vide. Il comprend une partie cylindrique 10 prolongée par une partie tronconique il destinée à faciliter son introduction dans le logement 6. The sheet 2 comprises, in its marginal zone 5, a stud 9 directed upwards, facing the housing 6. The stud 9 is obtained by plastic deformation of a part of the marginal zone 5, for example by vacuum thermoforming. It comprises a cylindrical part 10 extended by a frustoconical part it intended to facilitate its introduction into the housing 6.

Le téton 9 comprend par ailleurs deux saillies latérales 12, diamétralement opposées. The stud 9 also comprises two lateral projections 12, diametrically opposite.

Les dimensions du téton 9 sont agencées de telle sorte que le diamètre de sa partie cylindrique 10 soit inférieur à celui du logement 6, mais que la distance séparant les saillies 12 soit supérieure au diamètre du logement 6. The dimensions of the stud 9 are arranged such that the diameter of its cylindrical part 10 is less than that of the housing 6, but that the distance separating the projections 12 is greater than the diameter of the housing 6.

Les saillies 12 sont délimitées par des faces supérieures 13 et inférieures 14, qui sont inclinées pour faciliter l'introduction du téton 9 dans le logement 6 et son extraction hors de celui-ci. The projections 12 are delimited by upper 13 and lower 14 faces, which are inclined to facilitate the introduction of the stud 9 into the housing 6 and its extraction from the latter.

Pour associer les deux feuilles 1 et 2 et fermer la botte, on introduit le téton 9 dans le logement 6. Pendant l'introduction du téton dans le logement, les faces inclinées 13 des saillies coopèrent avec le rebord périphérique 15 de la zone non amincie 4 de la feuille 1, pour déformer élastiquement les parois du téton 9 et provoquer un effacement provisoire des saillies 12; celles-ci reprennent ensuite leur forme d'origine en repoussant et déformant élastiquement la paroi latérale cylindrique 7 du logement 6. To associate the two sheets 1 and 2 and close the boot, the stud 9 is introduced into the housing 6. During the introduction of the stud into the housing, the inclined faces 13 of the projections cooperate with the peripheral rim 15 of the unthinned zone. 4 of the sheet 1, to elastically deform the walls of the stud 9 and cause a temporary erasure of the projections 12; these then return to their original shape by pushing and elastically deforming the cylindrical side wall 7 of the housing 6.

Les figures 3 et 4 montrent le téton 9 engagé dans le logement 6. A la figure 4, on a omis de représenter la paroi de fond 8 du logement 6, afin de rendre le téton visible. Figures 3 and 4 show the stud 9 engaged in the housing 6. In Figure 4, we have omitted to represent the bottom wall 8 of the housing 6, in order to make the stud visible.

Dans cette position, les feuilles 1 et 2 sont assemblées, et
la feuille 1 a sa zone marginale non amincie 4 qui est coincée entre les saillies 12 du téton 9 et la feuille 2. Grâce à sa rigidité élevée, la zone non amincie 4 de la feuille l oppose une bonne résistance à l'extraction du téton 9 hors du logement 6.In this position, sheets 1 and 2 are assembled, and
the sheet 1 has its unthinned marginal zone 4 which is wedged between the projections 12 of the nipple 9 and the sheet 2. Thanks to its high rigidity, the unthinned zone 4 of the leaf l offers good resistance to the extraction of the nipple 9 outside the accommodation 6.

Cette résistance peut être calibrée facilement et avec précision, par un choix approprié du profil et des dimensions des saillies 12.This resistance can be easily and precisely calibrated by an appropriate choice of the profile and the dimensions of the projections 12.

La zone non amincie 4 de la feuille 1 exerce par ailleurs une résistance excessivement élevée à un glissement des feuilles 1 et 2 l'une sur l'autre. The unthinned zone 4 of the sheet 1 also exerts an excessively high resistance to sliding of the sheets 1 and 2 one on the other.

Pour faciliter l'insertion du téton 9 dans le logement 6 et surtout son extraction hors du logement, les zones marginales 4 et 5 présentent une échancrure 16, respectivement 17, au voisinage du logement 6, respectivement du téton 9. Les échancrures 16 et 17 sont ménagées de telle sorte qu'elles soient localisées respecti- vement de part et d'autre du téton 9 lorsque celui-ci est engagé dans le logement 6, comme représenté à la figure 4. Elles libèrent de la sorte deux pattes de préhension 18 et 19 sur les feuilles 1 et 2, sur lesquelles on peut agir avec les doigts de la main pour écarter les feuilles et extraire le téton du logement. To facilitate the insertion of the stud 9 in the housing 6 and especially its extraction from the housing, the marginal zones 4 and 5 have a notch 16, respectively 17, in the vicinity of the housing 6, respectively of the stud 9. The notches 16 and 17 are arranged so that they are respectively located on either side of the stud 9 when the latter is engaged in the housing 6, as shown in FIG. 4. They thus release two gripping tabs 18 and 19 on sheets 1 and 2, on which one can act with the fingers of the hand to spread the sheets and extract the stud from the housing.

Selon une variante, non représentée, de la forme d'exécution des figures 1 à 4, la paroi de fond 8 du logement 6 est supprimée, et la paroi latérale 7 est éventuellement raccourcie. Cette variante de l'invention permet d'exercer une poussée axiale sur le téton 9, par exemple avec un doigt de la main, pour l'expulser hors du logement 6. According to a variant, not shown, of the embodiment of Figures 1 to 4, the bottom wall 8 of the housing 6 is deleted, and the side wall 7 is optionally shortened. This variant of the invention makes it possible to exert an axial thrust on the nipple 9, for example with a finger of the hand, to expel it out of the housing 6.

Dans la forme de réalisation qui vient d'être décrite, en référence aux dessins annexés, on peut évidemment inverser les positions respectives du logement 6 et du téton 9, en prévoyant le logement 6 dans la zone marginale 5 de la feuille de fond 2 de la botte et le téton 9 dans la zone marginale 4 de la feuille de recouvrement 1 de la botte. In the embodiment which has just been described, with reference to the appended drawings, it is obviously possible to reverse the respective positions of the housing 6 and of the stud 9, by providing the housing 6 in the marginal zone 5 of the backsheet 2 of the boot and the stud 9 in the marginal zone 4 of the covering sheet 1 of the boot.

Le fond 2 et éventuellement le couvercle l peuvent avantageusement être conformés de manière à présenter des alvéoles contiguës, par exemple des alvéoles semi-ovoldes lorsque la botte est destinée à contenir des oeufs ou des objets de forme similaire.  The bottom 2 and possibly the cover l can advantageously be shaped so as to have contiguous cells, for example semi-oval cells when the boot is intended to contain eggs or objects of similar shape.

Bien que la description qui precede ait été appliquée spécif i- quement à un assemblage de feuilles constituant respectivement le couvercle et le fond d'une botte, il est évident que l'invention peut aussi avoir d'autres applications. Elle peut par exemple s 'appliquer aussi a un assemblage de feuilles profilées en forme de cageots superposés.  Although the above description has been applied specifically to an assembly of sheets constituting respectively the cover and the bottom of a boot, it is obvious that the invention can also have other applications. It can for example also be applied to an assembly of profiled sheets in the form of superimposed crates.
