amélioration du brevet français n 2.614.873. improvement of French Patent No. 2,614,873.
En effet la manière la plus évidente de réaliser un gobelet pliable est de partir d'une feuille semi rigide rectangulaire, de la plier en deux de manière à ce que les deux moitiés se superposent, de fixer entre eux les bords latéraux, et enfin de donner au fond du gobelet ainsi constitué une forme concave afin de maintenir le gobelet ouvert. La zone o l'on appuie les doigts naturellement, pour tenir le gobelet lorsqu'on le porte aux lèvres, correspond à la zone de plus grand écartement des parois du gobelet; cette zone concave est traversée par la ligne de pliage de la feuille de départ ainsi que par des lignes de pliage aléatoires qui peuvent se produire au moment de la formation du fond, surtout si l'opération est réalisée manuellement par une personne non avertie; toutes ces lignes de pliage constituent des zones de faiblesses, du verrouillage du fond concave, lorsqu'on tient le gobelet naturellement avec les doigts; et le gobelet a alors Indeed, the most obvious way to make a foldable cup is to start from a rectangular semi-rigid sheet, to fold it in two so that the two halves are superimposed, to fix between them the lateral edges, and finally to give the bottom of the cup thus formed a concave shape to keep the cup open. The zone where the fingers are naturally pressed, to hold the cup when it is held on the lips, corresponds to the zone of widest spacing of the walls of the cup; this concave zone is crossed by the fold line of the starting sheet as well as by random fold lines that can occur at the time of formation of the bottom, especially if the operation is performed manually by an uninformed person; all these fold lines constitute weak zones, concave bottom locking, when the cup is held naturally with the fingers; and the goblet then
tendance à retrouver sa forme initiale et à se collapser. tendency to return to its original form and to collapse.
On peut éviter le colapsage en tenant le gobelet par les bords latéraux o l'on a fixé ensembles les demi feuilles, mais ce n'est pas une position naturelle de la main. Le certificat d'addition français 2. 629.052 propose un mode de verrouillage, à l'aide des rabats de stabilisation décrits dans le brevet français n 2.614.873, qui est une solution efficace mais qui est complexe à mettre en oeuvre par l'utilisateur non averti. L'objet de l'invention est de proposer à l'utilisateur un gobelet dêpliable muni d'un fond ne comportant pas de lignes de pliage parasites qui sont la cause du collapsage des gobelets décrits dans les brevets cités; le déploiement du gobelet est rendu plus facile parce que le fond concave est formé en usine et ensuite plié de manière qu'une simple pression sur les arêtes latérales du gobelet plié permette l'ouverture de celui-ci. Dans ce qui Collapsing can be avoided by holding the cup by the side edges where the half-leaves are attached together, but this is not a natural position of the hand. The French addition certificate 2. 629.052 proposes a locking mode, using the stabilizing flaps described in French Patent No. 2,614,873, which is an effective solution but which is complex to implement by the user. not aware. The object of the invention is to provide the user with a removable cup provided with a bottom having no parasitic fold lines which are the cause of the collapse of the cups described in the cited patents; the deployment of the cup is made easier because the concave bottom is formed in the factory and then folded so that a simple pressure on the side edges of the bent cup allows the opening thereof. In what
suit, nous allons faire la description du formage du fond du following, we will do the description of the forming of the bottom of the
gobelet dans le cas du gobelet sans prendre en considération dans un premier temps l'existence éventuelle de rabats latéraux de stabilisation; en effet ces rabats font partie, au moment du pliage du fond, des bords latéraux du gobelet et leur présence ne modifie en rien la procédure de formage goblet in the case of the cup without first taking into consideration the possible existence of lateral stabilizing flaps; indeed these flaps are part, at the time of folding of the bottom, the side edges of the cup and their presence does not change the forming procedure

La Fig.9 représente le gobelet de la Fig.8 avec les rabats de stabilisation en place pour assurer l'équilibre de l'ensemble. Le gobelet selon l'invention est constitué à partir d'une feuille rectangulaire allongée Fig.1 constituée d'un matériau semi rigide; dans la partie centrale de la feuille Fig.1 on fait un rainage formant un losange (1) dont les angles des sommets opposés (2) situés au voisinage des cotés latéraux (3) sont aigus et placés, de préférence, sur la ligne médiane (4) de la feuille rectangulaire allongée; ce losange (1) délimite la surface du fond concave (5) du futur gobelet Fig.4 lorsqu'il est déployé. On superpose à ce premier losange (1) un deuxième rainage en forme de carré (6) ayant deux sommets (7) opposés confondus avec les sommets (2) du losange (1) situés sur la ligne médiane (4>; ce carré (6) est le fond du futur gobelet Fig.5 lorsqu'il est replié. Deux lignes (8) Fig.1 de rainage latérales parallèles aux plus grands côtés (3) de la feuille, et passant par les sommets communs (2) et (7) au carré (6) et au losange (1) délimitent la zone de fixation des bords latéraux (9) Fig.4 du gobelet entre eux. Une ligne de rainage centrale (10) Fig.1 parallèle aux grands cûtés (3) de la feuille passe par les autres sommets (11) et (12) du carré (6) et du losange (1); elle constitue notamment la Fig.9 shows the cup of Fig.8 with the stabilizing flaps in place to ensure the balance of all. The cup according to the invention consists of an elongated rectangular sheet Fig.1 made of a semi-rigid material; in the central part of the sheet Fig.1 is made a groove forming a rhombus (1) whose angles of the opposite peaks (2) located in the vicinity of the lateral sides (3) are acute and preferably placed on the center line (4) the elongate rectangular sheet; this rhombus (1) defines the surface of the concave bottom (5) of the future cup Fig.4 when it is deployed. This first rhombus (1) is superimposed on a second square-shaped crease (6) having two opposite peaks (7) coinciding with the vertices (2) of the rhombus (1) located on the center line (4>; 6) is the bottom of the future beaker Fig.5 when folded in. Two lines (8) Fig.1 of lateral scoring parallel to the longer sides (3) of the sheet, and passing through the common tops (2) and (7) squared (6) and rhombus (1) delimit the area of attachment of the lateral edges (9) Fig.4 of the cup between them.A central creasing line (10) Fig.1 parallel to the large cues (3). ) of the sheet passes through the other vertices (11) and (12) of the square (6) and the rhombus (1);
ligne de pliage du fond (5).folding line of the bottom (5).
Pour former le gobelet Fig.4 on plie progressivement la feuille Fig.1 suivant la ligne de rainage centrale (10) Fig.2 de manière à ce que la partie extérieure (13) du futur gobelet forme un creux; le fond (5) du futur gobelet qui était initialement un losange (1) Fig.1 se transforme en un dièdre formé de deux triangles isocèles (14) et (15) ayant leur base (16) commune et commence à constituer la concavité du fond (5); simultanément on appuie sur les zones (17) et (18) situées de part et d'autre du fond (5) jusqu'à ce que leur courbure s'inverse, par inversion du sens de pliage au niveau de la ligne de rainage centrale (10), et prennent une forme convexe formée de deux dièdres (21) et (22), avec une arete centrale (19) et (20), qui constitueront les faces latérales du gobelet Fig.4; en continuant le mouvement le fond concave (5) se creuse tandis que les bords (23) et (24) des dièdres convexes (21) et (22) situés de part et d'autre du fond concave (5), qui constituent les zones (9) Fig.4 de fixations des parois latérales entre elles, se rapprochent et viennent se superposer en fin de mouvement par repliage au niveau des rainages latéraux (8); il est possible alors de les fixer entre elles les parois latérales pour forme un To form the cup Fig.4 is gradually folded the sheet Fig.1 along the central creasing line (10) Fig.2 so that the outer portion (13) of the future cup forms a hollow; the bottom (5) of the future cup which was initially a rhombus (1) Fig.1 is transformed into a dihedron formed of two isosceles triangles (14) and (15) having their base (16) common and begins to constitute the concavity of the background (5); at the same time the zones (17) and (18) located on either side of the bottom (5) are pressed until their curvature is reversed, by inverting the folding direction at the level of the central creasing line (10), and take a convex shape formed of two dihedrons (21) and (22), with a central ridge (19) and (20), which will constitute the side faces of the cup Fig.4; continuing the movement the concave bottom (5) is hollowed out while the edges (23) and (24) of the convex dihedrals (21) and (22) located on either side of the concave bottom (5), which constitute the zones (9) Fig. 4 of attachments of the lateral walls to one another, approach each other and are superimposed at the end of the movement by folding at the level of the lateral creases (8); it is possible then to fix between them the side walls to form a
gobelet dont l'orifice supérieur a la forme d'un losange. cup whose upper orifice has the shape of a rhombus.
La zone du bord (25) Fig.6 qui sert à boire, se situe dans la zone o le bord (25) coupe la ligne centrale de pliage (10); la saisie du gobelet Fig.6 se fait naturellement au voisinage des extrémités (12) de la base commune (16) Fig.3 des deux triangles (14) et (15) formant le fond concave qui est constitué par un dièdre très résistant à la pression des doigts puisqu'il ne comporte pas de plis qui pourraient The zone of the edge (25) Fig.6 which serves to drink, is in the area where the edge (25) intersects the central fold line (10); the capture of the cup Fig.6 is naturally in the vicinity of the ends (12) of the common base (16) Fig.3 of the two triangles (14) and (15) forming the concave bottom which is constituted by a dihedron very resistant to finger pressure since it does not have any folds that could
constituer des amorces de flambage.constitute buckling primers.
Ensuite on appuie sur les arêtes (8> des zones (9) Fig.4 de raccordement des faces latérales (21) et (22), le fond concave (5) continue de se creuser, la zone (26) située entre ce qui était initialement le losange (1) Fig.1 représentant le fond (5) et le carré (6) se déforme progressivement; la ligne centrale de pliage (10) Fig.4 flambe dans cette zone (26) et cette surface devient progressivement, au fur et à mesure que les faces latérales (21) et (22) opposées se rapprochent, constituée de deux triangles rectangles isocèles (27) et (28), provenant du repliage du carré (6) Fig.1 sur lui-même, reliés par leur diagonale, qui est commune avec la base commune (16) Fig.2 des deux triangles (14) et (15) constituant le fond concave (5), et qui viennent se superposer Fig. 5. Le gobelet Fig.5 est alors replié avec les zones (9) de fixation des parois latérales opposées (21) et (22) situées dans la zone centrale du gobelet plié tandis que les arêtes (19) et (20) constituent maintenant les bords latéraux du gobelet plié, pour faciliter cette opération, on peut faire des rainages (29) Fig.1 formés de lignes parallèles entre elles et Then we press the edges (8> of the zones (9) Fig.4 connecting the side faces (21) and (22), the concave bottom (5) continues to widen, the area (26) located between what was initially the diamond (1) Fig.1 representing the bottom (5) and the square (6) is gradually deformed, the central line of folding (10) Fig.4 flames in this area (26) and this surface becomes progressively, as the opposite lateral faces (21) and (22) come together, consisting of two isosceles right triangles (27) and (28), coming from the folding of the square (6) Fig.1 on itself, connected by their diagonal, which is common with the common base (16) Fig.2 of the two triangles (14) and (15) constituting the concave bottom (5), and which are superimposed Fig. 5. The cup Fig.5 is then folded with the zones (9) for fixing the opposite side walls (21) and (22) located in the central zone of the folded cup while the ridges (19) and (20) constitute now the side edges of the bent cup, to facilitate this operation, it is possible to make creases (29) Fig.1 formed of parallel lines between them and
perpendiculaire à la ligne centrale de pliage (10). perpendicular to the central fold line (10).
Pour ouvrir le gobelet Fig.6, il suffit d'appuyer sur les bords latéraux (19) et (20) du gobelet plié Fig.5 et le mouvement inverse se produit jusqu'à ce que le fond concave (5) Fig.6 reprenne la forme initiale précédemment décrite Fig.4, formée de deux triangles (14) et (15) Fig.3 ayant un côté commun (16) qui est la petite diagonale du losange initial (1) Fig.1; quand on arrive dans cette position la dièdre formé par le fond concave (5) Fig.6 devient To open the cup Fig.6, just press the side edges (19) and (20) of the bent cup Fig.5 and the reverse movement occurs until the concave bottom (5) Fig.6 resumes the original form previously described Fig.4, formed of two triangles (14) and (15) Fig.3 having a common side (16) which is the small diagonal of the initial diamond (1) Fig.1; when one arrives in this position the dihedron formed by the concave bottom (5) Fig.6 becomes
résistant et le gobelet est en position dépliée. resistant and the cup is in the unfolded position.
La feuille rectangulaire initiale peut être prolongée des rabats (30) Fig.7 décrit dans le brevet cité avec une ligne de rainage (31) à leur base pour en permettre le pliage afin d'assurer la stabilité du gobelet Fig.9; à la fin du pliage du gobelet chaque rabat (30) est plié sur lui-même suivant son axe de symétrie qui est aussi le prolongement des bords latéraux (19) et (20); on déplie le gobelet Fig.8 comme précédemment décrit, les rabats (30) forment alors deux dièdres dont les arêtes (32) sont les prolongements des cûtés latéraux (19) et (20); on appuie sur les arêtes (32) au niveau des rainages (31) situés à la base des rabats (30) pour que les dièdres formés par les rabats (30) deviennent plans par simple déformation; il est alors possible de retourner les rabats (30) dont le sens de pliage s'inverse pour former un autre dièdre épousant la forme des parois latérales (21) et (22) Fig.9 du gobelet constituant ainsi des points d'appuis (33) rigides qui avec les appuis (34) d'extrémité des zones (9) de fixation des faces latérales (21) et (22) entre elles qui sont au voisinage des sommets The initial rectangular sheet may be extended flaps (30) Fig.7 described in the cited patent with a creasing line (31) at their base to allow folding to ensure the stability of the cup Fig.9; at the end of folding the cup each flap (30) is folded on itself along its axis of symmetry which is also the extension of the side edges (19) and (20); the cup FIG. 8 is unfolded as previously described, the flaps (30) then forming two dihedrons whose edges (32) are the extensions of the lateral sides (19) and (20); the edges (32) are pressed at the creases (31) at the base of the flaps (30) so that the dihedrons formed by the flaps (30) become flat by simple deformation; it is then possible to turn the flaps (30) whose folding direction reverses to form another dihedron matching the shape of the side walls (21) and (22) Fig.9 of the cup thus constituting bearing points ( 33) which with the end supports (34) of the zones (9) for fixing the lateral faces (21) and (22) between them which are in the vicinity of the vertices
