Definitions
- the invention relates to a capsule intended for use in the preparation of a hot drink by introducing water comprising a food substance such as coffee or similar.
- the invention relates more particularly to a capsule with improved opening and conservation.
- the emptying is done by breaking a pre-cut area to let an element of emptying in the form of a movable piston.
- the drink flows between the surface of the element and the circumference of item.
- the capsules do not have a long shelf life (around 2-3 months) due to the presence of the precut which can allow moisture or at least air to pass through.
- the capsule should be fully covered with a waterproof overwrap such as film sealed polymer. This adds to the cost of the capsule.
- the object of the present invention is to provide a simple, effective and inexpensive solution to these problems.
- the invention thus relates to a capsule comprising a portion of food substance for preparation a drink by mixing with a quantity of water comprising a body defining an enclosure for receive the substance characterized in that the body includes an opening suitable for the introduction of a element for emptying the capsule and in that the opening is sealed with a flexible membrane tearable and lower breaking strength by relation to the material of the body.
- the membrane comprises a metallic foil.
- the sheet must be tearable under the effect of introducing the drain element.
- the tear-off can be a function of the design of the drain element itself; this one can present a more or less cutting or piercing shape depending on the needs. However, the tear-off will be assessed relative to the non-tearable or low tearability of the body itself.
- the term "tearable” is therefore understood in its broad sense as encompassing any form of rupture such as cutting, tearing, puncturing, drilling, etc., except for those that can appear discrete pieces of material.
- the flexible membrane comprises a sheet of aluminum or aluminum alloy.
- Such material has the property of tearing itself clean and also that of being barrier to humidity and air thus making fully sealed opening.
- the membrane includes a thickness which allows a clean tear, freeing the opening of the body enough to create a suitable passage surface to the creation of foam and liquid flow and everything with a sufficient barrier effect. In this, the thickness is between 0.1 and 5 tenths of millimeters, preferably 1 and 3 tenths of a mm.
- the capsule body includes the capsule portion which defines the inner capacity to receive the substance to mix.
- the capsule is preferably made in formable material.
- formable material is meant a material that has the ability to take shape self-supporting defined.
- the material can be formed by different techniques such as injection, injection molding, hot compression, rotational molding, blowing, extrusion or any combination.
- the body must be resistant to internal pressure created. Such pressure can generally vary from 1 to 5 bars, more precisely from 1.5 to 2.5 bars.
- a formable capsule is by nature semi-rigid or rigid so that it can be put in place easily in a pressure chamber of a machine drink preparation. Such a machine is described in patent EP 0 125 215, the content of which is integrated in this application by reference. The capsule can so borrow different geometry and dimensions in depending on the capacity of the room to receive the capsule.
- the body is formed in a material selected from the group consisting of polypropylene, polyethylene, polyamide, polyester, polyvinylidene chloride, EVOH and combinations of one or more many of these plastics.
- the most material suitable seems to be polypropylene for its nutritional properties and the absence of salting out chemical.
- the body can have a thickness included between 0.5 and 3 mm, preferably 1 and 1.5 mm. Such a thickness is necessary to ensure a certain fit, resistance to pressure and sufficient barrier function to oxygen and humidity.
- the structure of the body can be variable. In general, it comprises a cup and a cover which is tightly attached to the edges of the cup.
- the cup is of sufficient size to receive the desired dose of substance; for example of the order of 1 to 25 grams of substance.
- the cup is closed on its open side by a cover.
- the cup has a bottom from which extends the opening adapted to the passage of the element for emptying the prepared mixture.
- the opening can take different forms depending on the shape of the drain element.
- the size of the opening is not critical as such. It can vary from 10 to 300 mm 2 .
- the opening and the drain element are of substantially complementary shape; the drain element being slightly smaller in size so as to create a passage surface for the flow of foam and then of the liquid mixture and also so as to avoid any significant mechanical interaction which can lead to the abrasion of parts of body material .
- the principle is that the emptying takes place between the surface of the element introduced into the opening and the opening itself or, alternatively, in conduits or channels formed in the element itself.
- the flexibility of the sealing membrane means that the emptying element can push back and release the membrane sufficiently towards the interior of the enclosure.
- the size of the passages determines the quality of the foam in the drink. Foam creation is also affected by speed of passage and internal pressure factors.
- the body cover can be provided with means allowing the passage of water in the capsule enclosure. These means may be holes allowing the passage of hot water.
- the external surface of the cover is provided with a peelable sealing means covering said passage means.
- the way sealing can be, for example, a sealed membrane or glued to the edges of the cover.
- the membrane can advantageously be identical in nature to that shuttering opening the cup.
- the substance in the capsule may be of a nature varied. It can be coffee, cocoa, tea, dairy product, ferments, soup, fruit or plants or any combination possible.
- the capsule of the prior art is visible in FIG. 1 through reference 10. It presents a part body 11 formed of a cup proper 12 and a cover 13 covering the cup. Both elements 12, 13 meet on peripheral edges 14 which can be connected by any suitable means of the mechanical type or by chemical adhesion or sealing or plastic.
- the cup contains a predetermined dose 15 of soluble substance such as coffee powder freeze-dried or atomized or a mixture of coffee and milk.
- the cover has holes 16, for example, two holes, for the passage of hot water under pressure when filling the internal cavity such as defined by the cover and the cup.
- the body 11 forms a substantially rigid or semi-rigid element able to take place in a preparation room waterproof whose shape is suitable for receiving said body.
- the cup On its lower surface or bottom, the cup comprises an opening means 17, such as a tablet non-waterproof precut, attached to the rest of the bottom of the cup.
- the tablet is broken at the precut areas by an element of piston type 20 at least part of which is introduced through the opening. The emptying is done by flow of the soluble mixture along the surface of item.
- an overpack can be planned to increase the conservation of the capsule.
- This overpack may include part of cup cover 18, part of cover of cover 19 which is assembled by sealing or other means level of a seal 20 located near the edges 14 of the body.
- Overpack is usually a material multi-layer polymer of type PS / EVOH / PE or the like.
- FIGS. 2 and 3 The identical references in FIG. 1 designate parties identical or equivalent. So, we find a body 11 formed by a cup 12 and a cover 19. In the case of the invention, the bottom of the cup is provided an opening 21 of shape adapted to the passage of a drain element 20. The opening is closed by a tear-away membrane 22 completely covering the opening tightly. The membrane is of sufficient size to overflow around the edge of the opening and reattach the edges of the opening by any means suitable connection such as sealing or adhesion by means an adhesive. The membrane can also be injected by over-injection on the body. The membrane can be placed either on the outer edges or on the inner edges of the opening.
- the membrane is designed to be of breaking strength lower than the strength of the body, especially from the bottom of the dome. Of even, the membrane is made of tearing material but does not not constituting discrete pieces separable from the part attached to the body. It is also so preferred to choose a means of membrane connection which has a higher breaking strength than the resistance of the membrane itself, so as to avoid the membrane to separate completely from the body.
- a peelable film 23 covering the cover 13.
- the film consists of airtight and moisture proof material such as aluminum or plastic, lined or not with a plastic film EVOH type or other.
- the film is sealed or stuck on the edges 14 of the capsule. In this case, we can plan an edge of sufficient width to allow sealing sufficient.
- Fig. 2 also shows a drain element 20 of beveled configuration allowing more tearing clean.
- the invention can avoid costly barrier overwrapping and not biodegradable completely covering the capsule.
- the user can simply delaminate the film 23 before use and place the capsule in the preparation chamber of a machine suitable for this use.
Abstract
Description
L'invention concerne une capsule prévue pour servir à la préparation d'une boisson chaude par introduction d'eau comprenant une substance alimentaire du type café ou similaire. L'invention se rapporte plus particulièrement à une capsule à ouverture et conservation améliorée.The invention relates to a capsule intended for use in the preparation of a hot drink by introducing water comprising a food substance such as coffee or similar. The invention relates more particularly to a capsule with improved opening and conservation.
Il est connu de préparer des boissons à partir de capsule jetables contenant une quantité prédosée de substance alimentaire. Il existe des systèmes utilisant la pression d'eau pour extraire une substance par percolation et extraction des arômes d'une substance non-entièrement soluble. C'est le cas notamment en partant de capsules contenant de la poudre de café torréfié-moulu. Il est nécessaire d'appliquer des pressions importantes de l'ordre de 10 bars et plus pour extraire correctement l'extrait de café. En général, la pression a pour effet d'ouvrir le fond de la capsule qui se déchire au contact de moyens en relief appropriés. Il existe aussi un système de préparation à partir de substances contenues dans la capsule qui se solubilisent au contact de l'eau et forment un mélange plus ou moins mousseux. Dans ce cas, une légère surpression suffit à créer le mélange. La vidange du mélange peut se faire par l'introduction d'un élément de vidange. La présente invention vise une amélioration de ce type de capsule.It is known to prepare drinks from capsules disposables containing a predosed amount of substance food. There are systems using pressure of water to extract a substance by percolation and extraction of aromas from a substance that is not entirely soluble. This is particularly the case starting from capsules containing roast-ground coffee powder. It is necessary to apply significant pressures of around 10 bars or more to extract correctly coffee extract. In general, pressure has the effect to open the bottom of the capsule which tears on contact appropriate relief means. There is also a system of preparation from contained substances in the capsule which dissolve on contact with water and form a more or less frothy mixture. In this In this case, a slight overpressure is enough to create the mixture. The emptying of the mixture can be done by the introduction of a drain element. The present invention relates to a improvement of this type of capsule.
Dans les capsules connues, la vidange se fait par cassure d'une zone prédécoupée pour laisser passer un élément de vidange sous forme de piston mobile. La boisson s'écoule entre la surface de l'élément et la circonférence de l'élément. L'un des problèmes rencontré vient de ce que la cassure peut engendrer la libération de petits morceaux de matière plastique qui se mélangent à la boisson.In known capsules, the emptying is done by breaking a pre-cut area to let an element of emptying in the form of a movable piston. The drink flows between the surface of the element and the circumference of item. One of the problems encountered is that breakage can lead to the release of small pieces of plastic that mix with the drink.
Un autre problème vient de ce que l'effet de cassure provoque une irrégularité de l'ouverture donc de la surface de passage alouée pour le mélange. Or, une telle irrégularité a tendance à affecter la qualité et la reproductibilité de la mousse qui est libérée en premier.Another problem is that the breaking effect causes an irregularity of the opening therefore of the passage surface allocated for mixing. Now, such irregularity tends to affect the quality and reproducibility of the foam which is released first.
Un autre problème vient: de ce que les capsules n'ont pas une grande durée de conservation (de l'ordre de 2-3 mois) en raison de la présence de la prédécoupe qui peut laisser passer l'humidité ou tout au moins l'air. Pour régler ce problème, la capsule doit être entièrement recouverte d'un suremballage étanche tel qu'un film polymère scellé. Ceci rajoute au coût de la capsule.Another problem is that the capsules do not have a long shelf life (around 2-3 months) due to the presence of the precut which can allow moisture or at least air to pass through. For fix this problem, the capsule should be fully covered with a waterproof overwrap such as film sealed polymer. This adds to the cost of the capsule.
Le but de la présente invention est d'apporter une solution simple, efficace et peu coûteuse à ces problèmes.The object of the present invention is to provide a simple, effective and inexpensive solution to these problems.
L'invention concerne ainsi une capsule comprenant une portion de substance alimentaire pour la préparation d'une boisson par mélange avec une quantité d'eau comprenant un corps définissant une enceinte pour recevoir la substance caractérisée en ce que le corps comprend une ouverture adaptée à l'introduction d'un élément de vidange de la capsule et en ce que l'ouverture est obturée de manière étanche par une membrane souple déchirable et de plus faible résistance à la rupture par rapport au matériau du corps.The invention thus relates to a capsule comprising a portion of food substance for preparation a drink by mixing with a quantity of water comprising a body defining an enclosure for receive the substance characterized in that the body includes an opening suitable for the introduction of a element for emptying the capsule and in that the opening is sealed with a flexible membrane tearable and lower breaking strength by relation to the material of the body.
On a constaté qu'une configuration de ce type apportait une solution satisfaisante à l'ensemble des problèmes posés. En particulier, on évite la formation de morceaux de matière dans la mesure où la fonction d'obturation de l'ouverture est traitée par un matériau de nature plus approprié par rapport au matériau constituant le corps de la capsule. On constate aussi une plus grande régularité de la surface de passage dégagée; ce qui permet un meilleur contrôle de la qualité et régularité de la mousse. De même, il n'est plus nécessaire d'emballer la capsule dans un suremballage coûteux et qui complique le procédé de fabrication de la capsule. En limitant l'emballage on réduit aussi avantageusement l'impact sur l'environnement.It has been found that a configuration of this type provides a satisfactory solution to all the problems posed. In particular, the formation of lumps is avoided matter as far as the shutter function of the opening is treated with a material of a more appropriate to the material of the body the capsule. There is also a greater regularity of the cleared passage surface; which allows a better quality control and regularity of foam. Likewise, it is no longer necessary to pack the capsule in an expensive overpack which complicates the method of manufacturing the capsule. Limiting packaging also advantageously reduces the impact on the environment.
De manière préférentielle, la membrane comprend une feuille métallique. La feuille doit être déchirable sous l'effet de l'introduction de l'élément de vidange. La déchirabilité peut être fonction de la conception de l'élément de vidange lui-même; celui-ci pouvant présenter une forme plus ou moins coupante ou perçante selon les besoins. Cependant, la déchirabilité s'appréciera relativement à la non-déchirabilité ou la faible déchirabilité du corps lui-même. Le terme "déchirable" s'entend donc dans son sens large comme englobant toute forme de rupture du type coupure, déchirure, crevaison, percement, etc., à l'exception de celles pouvant faire apparaítre des morceaux discrets de matière.Preferably, the membrane comprises a metallic foil. The sheet must be tearable under the effect of introducing the drain element. The tear-off can be a function of the design of the drain element itself; this one can present a more or less cutting or piercing shape depending on the needs. However, the tear-off will be assessed relative to the non-tearable or low tearability of the body itself. The term "tearable" is therefore understood in its broad sense as encompassing any form of rupture such as cutting, tearing, puncturing, drilling, etc., except for those that can appear discrete pieces of material.
De préférence, la membrane souple comprend une feuille en aluminium ou alliage d'aluminium. Un tel matériau a la propriété de se déchirer proprement et aussi celle d'être barrière à l'humidité et à l'air rendant ainsi l'ouverture totalement étanche. Toujours selon un aspect préféré, la membrane comprend une épaisseur qui permet une déchirure propre, dégageant l'ouverture du coprs suffisamment pour créer une surface de passage appropriée à la création de mousse et écoulement du liquide et tout en présentant un effet barrière suffisant. En cela, l'épaisseur est comprise entre 0.1 et 5 dixième de millimètres, de préférence, 1 et 3 dixièmes de mm.Preferably, the flexible membrane comprises a sheet of aluminum or aluminum alloy. Such material has the property of tearing itself clean and also that of being barrier to humidity and air thus making fully sealed opening. Always according to one aspect preferred, the membrane includes a thickness which allows a clean tear, freeing the opening of the body enough to create a suitable passage surface to the creation of foam and liquid flow and everything with a sufficient barrier effect. In this, the thickness is between 0.1 and 5 tenths of millimeters, preferably 1 and 3 tenths of a mm.
Le corps de la capsule comprend la partie de capsule qui définit la capacité intérieure pour recevoir la substance à mélanger. La capsule est de préférence réalisée en matériau formable. Par matériau "formable", on entend un matériau qui a la capacité de prendre une forme autoporteuse définie. Le matériau peut être formé par différentes techniques comme par injection, injection-moulage, compression à chaud, roto-moulage, soufflage, extrusion ou toutes combinaisons. Le corps doit être résistant à la pression interne créée. Une telle pression peut en général varier de 1 à 5 bars, plus précisément de 1.5 à 2.5 bars. Une capsule formable est par nature semi-rigide ou rigide de façon à pouvoir être mise en place facilement dans une chambre de pression d'une machine de préparation de boisson. Une telle machine est décrite dans le brevet EP 0 125 215 dont le contenu est intégré dans la présente demande par référence. La capsule peut ainsi emprunter différentes géométrie et dimensions en fonction de la capacité de la chambre à recevoir la capsule.The capsule body includes the capsule portion which defines the inner capacity to receive the substance to mix. The capsule is preferably made in formable material. By "formable" material is meant a material that has the ability to take shape self-supporting defined. The material can be formed by different techniques such as injection, injection molding, hot compression, rotational molding, blowing, extrusion or any combination. The body must be resistant to internal pressure created. Such pressure can generally vary from 1 to 5 bars, more precisely from 1.5 to 2.5 bars. A formable capsule is by nature semi-rigid or rigid so that it can be put in place easily in a pressure chamber of a machine drink preparation. Such a machine is described in patent EP 0 125 215, the content of which is integrated in this application by reference. The capsule can so borrow different geometry and dimensions in depending on the capacity of the room to receive the capsule.
A titre de mode préférentiel, le corps est formé dans un matériau sélectionné parmi le groupe consistant en polypropylène, polyéthylène, polyamide, polyester, polychlorure de vinylidène, EVOH et combinaisons d'un ou plusieurs de ces matières plastiques. Le matériau le plus approprié semble être le polypropylène pour ses propriétés alimentaires et l'absence de relargage chimique. Le corps peut avoir une épaisseur comprise entre 0.5 et 3 mm, de préférence 1 et 1.5 mm. Une telle épaisseur s'avère nécessaire pour assurer une certaine tenue en forme, une résistance à la pression et une fonction barrière suffisante à l'oxygène et l'humidité.As a preferred mode, the body is formed in a material selected from the group consisting of polypropylene, polyethylene, polyamide, polyester, polyvinylidene chloride, EVOH and combinations of one or more many of these plastics. The most material suitable seems to be polypropylene for its nutritional properties and the absence of salting out chemical. The body can have a thickness included between 0.5 and 3 mm, preferably 1 and 1.5 mm. Such a thickness is necessary to ensure a certain fit, resistance to pressure and sufficient barrier function to oxygen and humidity.
La structure du corps peut être variable. En général, il comporte une coupelle et un couvercle qui se rattache de manière étanche sur les bords de la coupelle. La coupelle est de taille suffisante pour recevoir la dose de substance désirée ; par exemple de l'ordre de 1 à 25 grammes de substance. La coupelle est fermée sur son côté ouvert par un couvercle. La coupelle possède un fond d'où s'étend l'ouverture adaptée au passage de l'élément de vidange du mélange préparé. L'ouverture peut prendre différentes formes en fonction de la forme de l'élément de vidange. La taille de l'ouverture n'est pas critique en tant que tel. Elle peut varier de 10 à 300 mm2. En général, l'ouverture et l'élément de vidange sont de forme sensiblement complémentaire; l'élément de vidange étant de taille légèrement inférieure de façon à créer une surface de passage pour l'écoulement de mousse puis du mélange liquide et aussi de façon à éviter toute interaction mécanique importante pouvant conduire à l'abrasion de parties de matière du corps. Le principe est que la vidange se fait entre la surface de l'élément introduit dans l'ouverture et l'ouverture elle-même ou, alternativement, dans des conduits ou canaux ménagés dans l'élément lui-même. La souplesse de la membrane d'obturation fait que l'élément de vidange peut repousser et dégager la membrane suffisamment vers l'intérieur de l'enceinte. La taille des passages détermine la qualité de la mousse dans la boisson. La création de mousse est aussi affectée par des facteurs de vitesse de passage et de pression interne. On a déterminé qu'une surface totale de passage comprise entre 5 et 15 mm2, de préférence 8-10 mm2 pour une pression de l'ordre de 2-3 bars est nécessaire pour créer une mousse de qualité pour la confection de café, cappuccinno, latte, chocolat ou boissons du même type.The structure of the body can be variable. In general, it comprises a cup and a cover which is tightly attached to the edges of the cup. The cup is of sufficient size to receive the desired dose of substance; for example of the order of 1 to 25 grams of substance. The cup is closed on its open side by a cover. The cup has a bottom from which extends the opening adapted to the passage of the element for emptying the prepared mixture. The opening can take different forms depending on the shape of the drain element. The size of the opening is not critical as such. It can vary from 10 to 300 mm 2 . In general, the opening and the drain element are of substantially complementary shape; the drain element being slightly smaller in size so as to create a passage surface for the flow of foam and then of the liquid mixture and also so as to avoid any significant mechanical interaction which can lead to the abrasion of parts of body material . The principle is that the emptying takes place between the surface of the element introduced into the opening and the opening itself or, alternatively, in conduits or channels formed in the element itself. The flexibility of the sealing membrane means that the emptying element can push back and release the membrane sufficiently towards the interior of the enclosure. The size of the passages determines the quality of the foam in the drink. Foam creation is also affected by speed of passage and internal pressure factors. It has been determined that a total passage surface of between 5 and 15 mm 2 , preferably 8-10 mm 2 for a pressure of the order of 2-3 bars is necessary to create a quality foam for making coffee. , cappuccinno, latte, chocolate or similar drinks.
Le couvercle du corps peut être muni de moyens permettant le passage d'eau dans l'enceinte de la capsule. Ces moyens peuvent être des trous permettant le passage de l'eau chaude. De préférence, la surface externe du couvercle est munie d'un moyen d'étanchéité pelable recouvrant lesdits moyens de passage. Le moyen d'étanchéité peut être, par exemple, une membrane scellée ou collée sur les bords du couvercle. La membrane peut être avantageusement de nature identique à celle obturant l'ouverture de la coupelle.The body cover can be provided with means allowing the passage of water in the capsule enclosure. These means may be holes allowing the passage of hot water. Preferably, the external surface of the cover is provided with a peelable sealing means covering said passage means. The way sealing can be, for example, a sealed membrane or glued to the edges of the cover. The membrane can advantageously be identical in nature to that shuttering opening the cup.
La substance contenue dans la capsule peut être de nature variée. Il peut s'agir de poudres de café, cacao, thé, produit laitier, ferments, potage, fruits ou plantes ou toute combinaison envisageable.The substance in the capsule may be of a nature varied. It can be coffee, cocoa, tea, dairy product, ferments, soup, fruit or plants or any combination possible.
La suite de la description est faite en référence aux
dessins dans lesquels :
La capsule de l'art antérieur est visible sur la Fig. 1
au travers de la référence 10. Elle présente une partie
de corps 11 formé d'une coupelle proprement dit 12 et
d'un couvercle 13 recouvrant la coupelle. Les deux
éléments 12, 13 se rejoignent sur des bords périphériques
14 qui peuvent être connecté par tout moyen approprié du
type mécanique ou par adhésion ou scellage chimique ou
plastique. La coupelle renferme une dose prédéterminée 15
de substance soluble tel que de la poudre de café
lyophilisé ou atomisé ou encore un mélange de poudre de
café et de lait. Le couvercle possède des trous 16, par
exemple, deux trous, pour le passage de l'eau chaude sous
pression lors du remplissage de la cavité interne telle
que définie par le couvercle et la coupelle. Le corps 11
forme un élément sensiblement rigide ou semi-rigide
capable de prendre place dans une chambre de préparation
étanche dont la forme est appropriée à recevoir ledit
corps. Sur sa surface inférieur ou fond, la coupelle
comprend un moyen d'ouverture 17, tel qu'une pastille
non-étanche prédécoupée, rattaché au reste du fond de la
coupelle. Lors du cycle de préparation, la pastille est
cassée au niveau des zones de prédécoupe par un élément
du type piston 20 dont une partie au moins est introduite
au travers de l'ouverture. La vidange se fait par
écoulement du mélange soluble le long de la surface de
l'élément. Comme le montre la figure, un suremballage
peut être prévu pour augmenter la conservation de la
capsule. Ce suremballage peut comprendre une partie de
couverture de coupelle 18, une partie de couverture de
couvercle 19 qui s'assemble par scellage ou autre au
niveau d'un joint 20 situé aux abords des bords 14 du
corps. Le suremballage est en général un matériau
polymère multi-couche du type PS/EVOH/PE ou similaire.The capsule of the prior art is visible in FIG. 1
through
L'invention est visible sur les Fig. 2 et 3. Les
références identiques à la Fig. 1 désignent des parties
identiques ou équivalentes. Ainsi, on retrouve un corps
11 formé d'une coupelle 12 et d'un couvercle 19. Dans le
cas de l'invention, le fond de la coupelle est munie
d'une ouverture 21 de forme adaptée au passage d'un
élément de vidange 20. L'ouverture est obturée par une
membrane 22 déchirable recouvrant entièrement l'ouverture
de manière étanche. La membrane est de taille suffisante
pour déborder sur le pourtour de l'ouverture et se
rattacher sur les bords de l'ouverture par tout moyen de
connexion approprié tel que scellage ou adhésion au moyen
d'un adhésif. La membrane peut aussi être injectée par
sur-injection sur le corps. La membrane peut être placée
soit sur les bords externes soit sur les bords internes
de l'ouverture. La membrane est conçue pour être de
résistance à la rupture inférieure à la résistance du
corps, notamment de la partie du fond de la coupole. De
même, la membrane est en matériau déchirant mais ne
constituant pas de morceaux discrets séparables de la
partie rattachées sur le corps. Il est ainsi aussi
préféré de choisir un moyen de connexion de la membrane
qui soit de résistance à la rupture supérieure à la
résistance de la membrane elle-même, de façon à éviter à
la membrane de se désolidariser entièrement du corps.The invention can be seen in FIGS. 2 and 3. The
