Abstract
Soupape pour l'évacuation de la vapeur d'un contenant consistant en un film soupape (5) soudé à la surface interne de la feuille de couverture (15) du contenant de manière à se trouver exposé lorsqu'une portion de la feuille de couverture (15) est détachée suivant une ligne de rupture préétablie (1).Valve for evacuating the vapor from a container consisting of a valve film (5) welded to the internal surface of the cover sheet (15) of the container so as to be exposed when a portion of the cover sheet (15) is detached along a pre-established rupture line (1).
Description
L'invention concerne une soupape pour l'évacuation de la vapeur de contenants consistant en un film soupape (5) soudé à la surface interne de la feuille de couverture du contenant de manière à se trouver exposé lorsque la feuille de couverture (15) est détachée suivant une ligne de rupture préétablie (1).The invention relates to a valve for the evacuation of vapor from containers consisting of a valve film (5) welded to the internal surface of the cover sheet of the container so as to be exposed when the cover sheet (15) is detached along a pre-established breaking line (1).
L'invention concerne plus particulièrement une soupape telle qu'elle vient d'être définie, et caractérisée en ce que le film constituant cette soupape possède une structure microporeuse ou poreuse qui assure sa perméabilité aux gaz et à la vapeur, et une composition qui rend le film résistant à l'eau et imperméable aux liquides et aux colloïdes.The invention relates more particularly to a valve as it has just been defined, and characterized in that the film constituting this valve has a microporous or porous structure which ensures its permeability to gases and to vapor, and a composition which makes water resistant film impermeable to liquids and colloids.
L'objet de l'invention décrite ci-dessous est une soupape incluse dans la feuille de couverture d'un contenant qui permet aux vapeurs formées durant le réchauffement du contenu de s'échapper, et qui empêche le milieu utilisé pour le réchauffement (habituellement l'eau) de pénétrer dans le contenant.The object of the invention described below is a valve included in the cover sheet of a container which allows the vapors formed during the heating of the contents to escape, and which prevents the medium used for heating (usually water) from entering the container.
La dilatation du liquide et son évaporation lorsqu'un plat préparé mis dans un récipient semi-rigide est réchauffé produit une surpression qui provoque le jaillissement de liquide chaud.au moment de l'ouverture du récipient. Ceci peut amener des restrictions à l'emploi de plats préparés, qui par ailleurs sont très commodes.The expansion of the liquid and its evaporation when a prepared dish placed in a semi-rigid container is reheated produces an overpressure which causes the hot liquid to spurt out when the container is opened. This can lead to restrictions on the use of prepared meals, which, moreover, are very convenient.
L'invention décrite ci-dessous résoud ce problème en incluant une soupape dans la feuille de couverture qui est mise en état de fonctionner juste avant qu'on réchauffe le récipient et son contenu.The invention described below solves this problem by including a valve in the cover sheet which is put into working condition just before the container and its contents are heated.
- La Fig. 1 est une vue transversale de la feuille de couverture et de la soupape d'évacuation faisant l'objet de l'invention.Fig. 1 is a transverse view of the cover sheet and of the discharge valve forming the subject of the invention.
- La Fig. 2 est une vue transversale du système représsnte. sur la Fig. 1 après l'anlèvement de la feuille de protection.Fig. 2 is a transverse view of the system represented. in Fig. 1 after removal of the protective sheet.
- La Fig. 3 est une vue d'en haut de la soupape d'éveaouation faisant l'objet de l'invention.Fig. 3 is a top view of the discharge valve forming the subject of the invention.
- La Fig. 4 est un exemple de contenant muni d'une feuille de couverture détachatie pourvue de la soupape d'évacuation faisant l'objet de l'invention.Fig. 4 is an example of a container provided with a detachment cover sheet provided with the discharge valve forming the subject of the invention.
Dans cette invention. une ligne de déchirure (1) qui est totalement indépendante de la ligne de déchirure suivant laquelle le contenant est ouvert permet de soulever une portion de la feuil le de couverture (15) créant ainsi une ouverture qui reste toutefois fermée par un film (5) soudé sur la surface interne de la feuille de couverture.In this invention. a tear line (1) which is completely independent of the tear line along which the container is opened makes it possible to lift a portion of the cover sheet (15) thus creating an opening which remains however closed by a film (5) soldered to the inner surface of the cover sheet.
La feuille de couverture comprend trois composantes prin- eipales: un film externe à faible élasticité (2) recouvert d'une couche de plastique (3), cette couche de piastique (3) étant scellée à un film (4) ayant la même composition.The cover sheet comprises three main components: an external film with low elasticity (2) covered with a layer of plastic (3), this layer of piastic (3) being sealed with a film (4) having the same composition .
Lorsque le film (4) est un film composite à plusieurs couches, il est indispensable que la couche externe de ce film ait la même composition que la couche plastique (3).When the film (4) is a composite film with several layers, it is essential that the outer layer of this film has the same composition as the plastic layer (3).
La film soupape (5) faisant l'objet de la présente invention est constitué du même matériau que le film (4); ou la couche intérieure du film (4) et il est scellé hermétiquement à ce film par soudage au aiveau de la zone (7) caractérisée par un creux (6). Le tracé de la soudure est représenté par la zone pointilléeThe valve film (5) forming the subject of the present invention is made of the same material as the film (4); or the inner layer of the film (4) and it is hermetically sealed to this film by welding with the level of the zone (7) characterized by a recess (6). The weld line is represented by the dotted area
Le film soupape (5) est fait à partir de films microporaux bien connus résistant à la pénétration de l'eau.The valve film (5) is made from well known microporal films resistant to the penetration of water.
Pendant l'opération de fabrication de la feuille de couverture pour le contenant, une incision (1) constituant la ligne de rupture préétablie est faite à l'intérieur de la zone délimitée par la ligne (7) qui correspond à la ligne de soudure du film soupape. La ligne de soudure (8) suivant laquelle le film (2) est soudé au film (4) par l'intermédiaire de la couche plastique (3) - cette ligne de soudure (8) correspond à la zone de soudure (14) et au creux (9) de la vue transversale représentée-sur la Fig. 1 - coïncide avec la majeure partie du tracé de l'incision (l), exception faite de la languette d'ouverture, où la ligne de soudure (8) se termine en une pointe à laquelle la déchirure débute.During the manufacturing process of the hatch sheet For the container, an incision (1) constituting the pre-established rupture line is made inside the zone delimited by the line (7) which corresponds to the weld line of the valve film. The weld line (8) along which the film (2) is welded to the film (4) via the plastic layer (3) - this weld line (8) corresponds to the weld zone (14) and in the hollow (9) of the transverse view shown in FIG. 1 - coincides with most of the course of the incision (l), except for the opening tab, where the weld line (8) ends in a point at which the tearing begins.
Lorsque la languette de la feuille de couverture est détachée suivant l'incision (1) et la ligne de soudure (8), le film soupape (5) se trouve exposé, cette opération étant facilitée par l'incision (1).When the tab of the cover sheet is detached along the incision (1) and the weld line (8), the valve film (5) is exposed, this operation being facilitated by the incision (1).
Le film soupape (5) est exposé juste avant qu'on réchauffe le récipient et son contenu. Le film soupape (5) permet à la vapeur produite à l'intérieur du contenant durant son réchauffement de sortir, tout en empêchant le liquide de s'échapper, ou à l'eau utilisée pour le réchauffement de rentrer. La pression normalement produite pendant le réchauffement se trouve ainsi réduite, et le contenant peut être ouvert sans que ne se produisent des projections de liquide chaud.The valve film (5) is exposed just before the container and its contents are heated. The valve film (5) allows the vapor produced inside the container during heating to exit, while preventing the liquid from escaping, or the water used for heating to return. The pressure normally produced during reheating is thus reduced, and the container can be opened without splashing of hot liquid.
Le film externe (2) est constitué d'un matériau à faible élasticité comme l'aluminium, le papier, certains plastiques ou d'autres matériaux à faible élasticité. Le film (2) est pourvu d'une couche fine adhésive (3) constituée de la même substance thermoplastique que le film interne (4). Dans une opération préliminaire, une incision est faite dans le film (2) et la couche adhésive (3) dont le tracé correspond à la ligne de rupture préétablie (1) suivant laquelle la feuille sera déchirée.The outer film (2) is made of a material with low elasticity such as aluminum, paper, certain plastics or other materials with low elasticity. The film (2) is provided with a thin adhesive layer (3) made of the same thermoplastic substance as the internal film (4). In a preliminary operation, an incision is made in the film (2) and the adhesive layer (3), the line of which corresponds to the pre-breaking line. established (1) that the sheet will be torn.
Après cette opération d'incision, le film (2) est souoé au film (4) par l'intermdailaire de la couche adhésive (3). Comme c'est le cas de la majorité des films fabriqués par extrusion soufflage, le film (4) possède une orientation moléculaire biaxi- ale. Lors du soudage, le film thermoplastique est fondu, ce qui détruit en grande partie l'orientation moléculaire à laquelle le film doit pour l'essentiel sa résistance à la rupture.After this incision operation, the film (2) is subjected to the film (4) via the adhesive layer (3). As is the case with the majority of films produced by blow molding, the film (4) has a biaxial molecular orientation. During welding, the thermoplastic film is melted, which largely destroys the molecular orientation to which the film essentially owes its breaking strength.
La zone de soudure est encore affaiblie par le creux formé sous lTeffet de la pression exercée lors de l'opération de soudage. Des entailles produites par exemple par des arêtes ou par d'autres motifs de l'outil de soudage peuvent contribuer à augmenter encore la faiblesse de la ligne de soudure.The weld zone is further weakened by the hollow formed under the effect of pressure exerted T during the welding operation. Notches produced for example by edges or by other patterns of the welding tool can further increase the weakness of the weld line.
La languette de la feuille de couverture est détachée en l'agrippant avec les doigts. La déchirure débute à la pointe que forme la ligne de soudure (8) et se propage ensuite suivant la ligne de rupture préétablie (1) jusqu'à ce que toute la portion de feuille entourée par cette ligne soit détachée. Durant cette opération, le film (4) se déchire le long de la soudure en suivant la ligne de rupture (1).The tab of the cover sheet is detached by gripping it with your fingers. The tear begins at the tip formed by the weld line (8) and then propagates along the pre-established rupture line (1) until the entire portion of sheet surrounded by this line is detached. During this operation, the film (4) tears along the weld following the rupture line (1).
L'objet de l'invention est d'empêcher la surpression dans des contenants, et en particulier ceux remplis de produits alimentaires qui doivent être réchauffés avant leur consommation, géné- ralemet par immersion dans de l'eau bouillante. La soupape est hermétiquement soudée à la feuille de couverture avant l'utilisation; avant ou après que le contenant ait été réchauffé, la feuille de couverture est détachée, exposant ainsi la soupape. La soupape est constituée c'un film thermoplastique microporeux ou poreux scudé à la surface interne de la feuille de couverture. Le film de la soupape est perméable à la vapeur d'eau, mais imperméable à l'eau. Ceci empêche l'eau de réchauffement de se mélanger au contenu du récipient, et que ce contenu jaillisse au moment de l'ouverture.The object of the invention is to prevent overpressure in containers, and in particular those filled with food products which must be reheated before consumption, generally by immersion in boiling water. The valve is hermetically sealed to the cover sheet before use; before or after the container has been warmed, the cover sheet is peeled off, exposing the valve. The valve is made up of a microporous or porous thermoplastic film bonded to the internal surface of the cover sheet. The valve film is permeable to water vapor, but waterproof. This prevents the warming water from mixing with the contents of the container, and that this content gushes out upon opening.
