Description

       

  Emballage pour recevoir et atomiser de petites quantités

  
de liquide.

  
L'invention concerne un emballage formé de

  
deux sections de feuilles assemblées l'une avec l'autre

  
et destiné à contenir et atomiser de petites quantités

  
de liquide; cet emballage jonsiste en un récipient com-pressible, contenant le liquide, un système de canaux s'y raccordant pour son transport et un gicleur pour l'atomiser.

  
 <EMI ID=1.1> 

  
teux, des petits emballages à un coin desquels on forme un col dont l'extrémité libre est munie d'une manette pouvant s'enlever par une rotation, afin de faire apparaître l'embouchure irrégulière d'un canal avec des bavures et des saillies. Comme pour maintenir le petit emballage, on exerce une pression sur le récipient contenant le shampooing, il existe un risque de voir ce dernier s'échapper dès l'ouverture du canal. Pour empêcher dans une certaine mesure cet inconvénient, on sait aussi que l'on peut dégager, par sectionnement d'un coin) un système de canaux permettant d'expulser simultanément le liquide et l'air se trouvant à l'intérieur de l'emballage, pour obtenir ainsi un effet de jaillissement.

   Celui-ci ne se produit, toutefois, que si, au moment de la sortie du liquide, on maintient l'emballage dans une position déterminée dans laquelle des proportions d'air et de liquide aussi égales que possible sont distribuées. L'effet de jaillissement dépend en outre de la manière exactement prédéterminée dont la coupe est exécutée, car autrement, le système de canaux est muni d'une ou de plusieurs embouchures qui ne permettent absolument aucun effet de jaillissement ou ne permettent qu'un effet insuffisant. Ces deux conditions limitent considérablement la valeur d'utilisation des emballages connus. 

  
En revanche, le but de la présente invention est de créer un emballage pour recevoir et atomiser des petites quantités de liquide, qui puisse s'ouvrir de manière exactement prédéterminable, sans accessoires étrangers, uniquement par l'application d'une pression, par exemple.

  
Pour résoudre ce problème dans le cas de

  
 <EMI ID=2.1> 

  
l'invention propose d'associer au système de canaux

  
une barrière qui maintient le liquide dans le récipient, de conformer le système de canaux en vue de l'accélération du liquide, quand on applique une pression sur le récipient, et de le faire déboucher, en principe tangentiellement, dans au moins une chambre de tourbillonnement munie d'au moins une ouverture centrale de gicleur.

  
Ceci offre l'avantage que l'emballage peut être ouvert sans intervention d'un outil, tel que des ciseaux, par exemple. Le liquide est accumulé dans le récipient et quand l'ouverture du gicleur est fermée par une languette amovible, il est maintenu par l'air dans le système de canaux ou est séparé de ce système par

  
un point de rupture imposé s'ouvrant vers l'extérieur. Si on applique, par exemple, avec le pouce, une première pression sur le récipient, celui-ci s'ouvre au point de rupture imposé et une certaine quantité de liquide pénètre dans le système de canaux, de sorte que l'air se trouvant dans le système est expulsé par le gicleur tou-jours ouvert. Si on accentue la pression sur le récipient, celui-ci se vide dans le système de canaux dont

  
la section transversale diminue en direction de l'ouverture du gicleur, en vue d'accélérer le liquide. Dans la chambre de tourbillonnement, le liquide déjà accéléré

  
est entraîné dans un mouvement giratoir avant de sortir finement pulvérisé, de l'ouverture du gicleur. Il se 

  
forme ainsi un nuage conique de minuscules gouttelettes

  
de liquide. Il ne se produit aucune perte de liquide

  
et le cône de pulvérisation présente une forme toujours constante, d'autant plus que le système de canaux ne

  
doit pas être dégagé au moyen d'outils et qu'il est établi, la chambre de tourbillonnement comprise, avec le gicleur déjà ouvert et restant tel, même au cours du transport et de l'emmagasinage des emballages. La fabrication

  
de l'emballage est simplifiée du fait qu'il faut simplement emboutir la feuille pour obtenir le récipient avec

  
le systèrne de canaux et la chambre de tourbillonnement.

  
Le récipient est ensuite rempli et la feuille emboutie

  
est assemblée avec une autre feuille plane. En dernière phase, on peut séparer les emballages individuels, remplis, de la bande continue, ce qui peut se faire simultanément à l'assemblage des deux feuilles qui sont, de  préférence, soudées l'une à l'autre. 

  
L'emballage de l'invention convient pour

  
être employé une seule fois et pour les liquidas les

  
plus divers. On peut l'utiliser en premier lieu pour

  
les parfums, les eaux de toilette, les laques capillaires,  etc. On peut toutefois aussi l'appliquer pour l'atomisation de substances stérilisées ou stérilisantes dans le domaine de la médecine. L'emballage fermé peut éventuellement être stérilisé dans une autre enveloppe, au moyen d'un rayonnement ultra-violet, par exemple; dans la salle d'opération, on écarte l'enveloppe extérieure et, en exerçant une pression sur le récipient, le chirurgien ouvre celui-ci au point de rupture imposé

  
et peut alors stériliser immédiatement l'endroit à traiter. il est en outre avantageux que l'emballage ne contienne aucun propulseur et qu'aucun corps étranger

  
ne soit nécessaire pour sa fermeture ni pour son ouverture. L'emballage atomiseur peut aussi trouver son em-  ploi dans le domaine des produits alimentaires, pour 

  
i l'huile ou le vinaigre, par exemple; il peut avoir la forme d'un récipient mélangeur dans lequel une première pression écarte une c loison, ce qui permet le mélange  des liquides se trouvant à l'intérieur du récipient avant leur entrée dans le système de canaux et leur atomisation.

  
Le liquide peut aussi consister en une quantité déterminée de laque, pulvérisée, en vue d'une réparation, sur des pièces endommagées d'un véhicule automobile, par exemple.

  
L'emballage convient aussi pour l'atomisation d'autres liquides employés comme moyens de destruction de la vermine ou des mauvaises herbes. 

  
 <EMI ID=3.1> 

  
ou la pulvérisation, on prévoit en outre, entre le ré-  cipient et la chambre de tourbillonnement, deux canaux décalés d'un angle de 180[deg.] et débouchant tangentiellement  dans cette chambre. 

  
Quand le récipient compressible, les canaux

  
et la chambre de tourbillonnement sont formés d'une  feuille de polyéthylène emboutie, il est avantageux de  former l'ouverture du gicleur simultanémént à l'emboutis-  sage. Cette ouverture se trouve alors dans la paroi, de  forme stable, de la chambre de tourbillonnement, aussi insensible aux chocs que la paroi des canaux, car l'épais-  seur originelle de la feuille de polyéthylène est, en  principe, conservée . 

  
D'autres formes avantageuses de l'invention sont prévues.

  
On décrira ci-après, de façon plus détaillée, des exemples d'exécution de l'invention illustrés dans

  
les dessins annexés, où :
la figure 1 montre en plan la feuille emboutie; la figure 2 montre, dans une vue de profil, la feuille emboutie de la figure 1; la figure 3 montre la feuille plane vue de profil; la figure 4 montre, en plan, la feuille plane de la figure 3; la figure 5 montre, en plan, la feuille emboutie assemblée avec la feuille plane; la figure 6 montre, dans une vue de profil, la feuille emboutie de la figure 5, assemblée avec la feuille plane; la figure 7 montre l'emballage vu de profil, après formation du point de rupture imposé, selon une première forme d'exécution; la figure 8 montre l'emballage vu de profil; après formation du point de rupture imposé, selon une seconde forme d'exécution; la figure 9 montre, dans une vue en plan, l'emballage selon une troisième forme d'exécution;

   la figure 10 montre l'emballage de la figure 9, vu de profil, et la figure 11 montre, vu de profil, l'emballage selon une quatrième forme d'exécution.

  
Les figures 1 et 2 montrent une section d'une feuille 1 de polyéthylène emboutie, séparée d'une file ou d'une bande continue. Cette feuille 1 est avantageusement translucide. Elle présente une chambre de tourbillonnement 2 à laquelle se raccorde, par deux canaux

  
3 et 4, un récipient 5, compressible, destiné à recevoir, le liquide. Ce récipient 5 est plus profond que la chambre de tourbillonnement 2 et que les canaux 3 et 4, ce qui accélère le liquide se trouvant à l'intérieur de ces derniers. Dans le premier exemple d'exécution, une feuille plane 6, de préférence une feuille d'aluminium, présente une ouverture de gicleur 7. Au moment de l'as-semblage de la feuille emboutie 1 et de la feuille plane 

  
6, suivant les flèches entre les figures 2 et 3, l'ou-  verture 7 est alignée exac tement sur le centre de la 

  
chambre de tourbillonnement 2. Entre le récipient 5  et la chambre de tourbillonnement 2, sont prévus les

  
deux canaux 3 et 4, décalés d'un angle de 180[deg.] et débouchant tangentiellement dans la chambre 2. Les deux canaux peuvent présenter une certaine conicité et se  rétrécir depuis le récipient 5, en direction de la chambre 2 dont l'ouverture 7, selon la figure 6 est fermée

  
par une languette 27. Le liquide est retenu dans le récipient 5 par l'air se trouvant dans les deux canaux

  
3 et 4. Ces derniers ont des sections 9 parallèles, de section transversale en principe constante, dont les extrémités 10 sont coudées à peu près à angle droit, se rétrécissent fortement et débouchent tangentiellement

  
dans la chambre de tourbillonnement 2, en des points

  
de celle-ci diamétralement opposés.

  
Au lieu de la languette 27, on peut prévoir, entre les canaux 3 et 4 et le récipient 5, un point de  rupture imposé 8. Dans la région du point 8, on peut prévoir, à côté du récipient 5, une antichambre 11, en communication avec les deux canaux 3 et 4, mais séparée, toutefois, par le point de rupture imposé 8 du récipient

  
5, aussi longtemps que le liquide est enfermé dans

  
celui-ci. Pour faciliter la séparation au point 8, le récipient peut être chanfreiné, comme indiqué en 12, en vue d'obtenir un effet de coin à ce point 8, quand on applique une pression avec le doigt dans le sens de la flèche 13 de la figure 6, et de faciliter ainsi la séparation des feuilles 1 et 6.

  
Dans l'exemple d'exécution de la figure 7, le point de rupture imposé 8 revêt la forme d'un assemblage 14 où une cannelure 17 ménagée dans la feuille emboutie 1 est collée en un point 16 de la feuille plane
6.

  
Dans l'exemple de la figure 8, le point de rupture imposé 8 est obtenu en pratiquant un estampage profond 15 après ou pendant l'assamblage de la feuille emboutie 1 avec la feuille plane 6; il se forme ainsi, dans la feuille 6, une nervure 18 en saillie qui est en prise étanche avec une nervure 19, rentrante, de la feuille emboutie.

  
Dans l'exemple des figures 9 et 10, la feuille d'aluminium plane 6 est recouverte par une feuille thermoplastique 20 de faible épaisseur, une feuille de polyéthylène par exemple. Ces feuilles d'aluminium 6 et de polyéthylène 20 ne présentent aucune ouverture

  
et l'ouverture 7 du gicleur est formée en même temps que l'emboutissage dans le centre de la chambre de tourbillonnement 2. Après remplissage du récipient 5 par du liquide, la feuille de polyéthylène emboutie 1, ouverte vers le haut, est recouverte par la feuille d'aluminium 6, également revêtue d'une mince feuille

  
de polyéthylène 20, puis les feuilles sont soudées ensemble sous la chaleur et sous pression, de manière à obtenir un récipient fermé de tous cotés pour le liquide, tandis que tout le système de canaux 11, 9, 10 s'ouvre par l'ouverture 7 dans la chambre de tourbillonnement 2. L'assemblage de la mince feuille de polyéthylène 20

  
avec la feuille plane 6 d'alurninium est, tout au moins dans la région du point de rupture imposé 8, d'une résistance tellement faible qu'en exerçant une première pression dans le sens de la flèche 13 sur le récipient 5, la mince feuille de polyéthylène 20 se sépare de la feuille d'aluminium 6 et s'ouvre de telle façon qu'à proximité du biseau 12 et du point de rupture 8 ouvert, le liquide peut s'écouler librement dans les canaux

  
3 et 4.

  
Dans l'exemple de la figure 11, le récipient

  
5 comprend deux chambres dont l'une 21 est complètement remplie de liquide, tandis qu'une autre 22 contient encore de l'air en plus d'un autre liquide. Entre les deux chambres 21 et 22, se trouve une cloison 23 qui se brise quand on applique sur la chambre 21 la première pression dans le sens de la flèche 13. Les liquides des deux chambres 21 et 22 peuvent ainsi se mélanger à l'intérieur du récipient 5. Une autre pression ouvre ensuite le point de rupture 8 et en l'accentuant de façon continue, le mélange peut être atomisé en sortant de l'ouverture 7 du gicleur.

  
La feuille plane 6 peut aussi être en une matière synthétique tel que le PVC et être recouverte

  Packaging for receiving and atomizing small quantities

  
of liquid.

  
The invention relates to a package formed from

  
two sections of sheets assembled together

  
and intended to contain and atomize small amounts

  
liquid; this packaging jonsiste in a compressible container, containing the liquid, a system of channels connecting to it for its transport and a nozzle for atomizing it.

  
 <EMI ID = 1.1>

  
teux, small packages at one corner of which a neck is formed, the free end of which is provided with a handle which can be removed by rotation, in order to reveal the irregular mouth of a channel with burrs and protrusions . As to maintain the small package, pressure is exerted on the container containing the shampoo, there is a risk of the latter escaping as soon as the channel is opened. To prevent this drawback to a certain extent, it is also known that it is possible to release, by sectioning a corner) a system of channels making it possible to simultaneously expel the liquid and the air located inside the tube. packaging, thereby obtaining a spouting effect.

   This only occurs, however, if, at the moment of the liquid being released, the packaging is kept in a determined position in which as equal proportions of air and liquid as possible are distributed. The spouting effect further depends on the exactly predetermined way in which the cut is executed, because otherwise the channel system is provided with one or more mouthpieces which either allow absolutely no spouting effect or only allow an effect. insufficient. These two conditions considerably limit the value of use of known packaging.

  
On the other hand, the aim of the present invention is to create a package for receiving and atomizing small quantities of liquid, which can be opened in an exactly predetermined manner, without foreign accessories, only by the application of pressure, for example. .

  
To resolve this problem in the case of

  
 <EMI ID = 2.1>

  
the invention proposes to associate with the channel system

  
a barrier which maintains the liquid in the container, to shape the system of channels with a view to the acceleration of the liquid, when pressure is applied to the container, and to cause it to emerge, in principle tangentially, into at least one chamber of vortex with at least one central nozzle opening.

  
This offers the advantage that the package can be opened without the intervention of a tool, such as scissors, for example. The liquid is accumulated in the container and when the nozzle opening is closed by a removable tab, it is held by air in the channel system or is separated from this system by

  
an imposed breaking point opening outwards. If one applies, for example, with the thumb, a first pressure on the container, this one opens at the imposed breaking point and a certain quantity of liquid enters the system of channels, so that the air present in the system is expelled through the still open nozzle. If the pressure is increased on the container, it empties into the system of channels whose

  
the cross section decreases in the direction of the nozzle opening, in order to accelerate the liquid. In the swirl chamber, the already accelerated liquid

  
is driven in a rotating movement before coming out finely pulverized from the nozzle opening. It is

  
thus forms a conical cloud of tiny droplets

  
of liquid. There is no loss of fluid

  
and the spray cone has an always constant shape, especially since the channel system does not

  
must not be removed by means of tools and that it is established, including the swirl chamber, with the nozzle already open and remaining such, even during transport and storage of the packaging. The making

  
packaging is simplified by the fact that it is simply necessary to emboss the sheet to obtain the container with

  
the channel system and the swirl chamber.

  
The container is then filled and the foil stamped

  
is assembled with another flat sheet. In the final phase, the individual, filled packages can be separated from the continuous strip, which can be done simultaneously with the assembly of the two sheets which are preferably welded to one another.

  
The packaging of the invention is suitable for

  
be used only once and for liquidation

  
more diverse. It can be used primarily for

  
perfumes, colognes, hair lacquers, etc. However, it can also be applied for the atomization of sterilized or sterilizing substances in the field of medicine. The closed packaging can optionally be sterilized in another envelope, by means of ultra-violet radiation, for example; in the operating room, the outer casing is removed and, by exerting pressure on the container, the surgeon opens it at the imposed breaking point

  
and can then immediately sterilize the area to be treated. it is also advantageous that the packaging does not contain any propellant and that no foreign matter

  
is not necessary for its closing or for its opening. The atomizer packaging can also find its use in the field of food products, for

  
i oil or vinegar, for example; it may be in the form of a mixing vessel in which a first pressure pushes aside a c loion, which allows the liquids found inside the vessel to be mixed before they enter the channel system and their atomization.

  
The liquid can also consist of a determined quantity of lacquer, sprayed, with a view to repairing, on damaged parts of a motor vehicle, for example.

  
The packaging is also suitable for atomizing other liquids used as a means of destroying vermin or weeds.

  
 <EMI ID = 3.1>

  
or spraying, there are also provided, between the receptacle and the swirl chamber, two channels offset by an angle of 180 [deg.] and opening tangentially into this chamber.

  
When the compressible container, the channels

  
and the swirl chamber are formed from a stamped polyethylene sheet, it is advantageous to form the nozzle opening simultaneously with the stamping. This opening is then located in the wall, of stable form, of the swirl chamber, as insensitive to impacts as the wall of the channels, because the original thickness of the polyethylene sheet is, in principle, retained.

  
Other advantageous forms of the invention are provided.

  
Exemplary embodiments of the invention illustrated in

  
the accompanying drawings, where:
Figure 1 shows in plan the stamped sheet; Figure 2 shows, in a side view, the stamped sheet of Figure 1; FIG. 3 shows the planar sheet seen in profile; Figure 4 shows, in plan, the flat sheet of Figure 3; FIG. 5 shows, in plan, the stamped sheet assembled with the flat sheet; Figure 6 shows, in a side view, the stamped sheet of Figure 5, assembled with the flat sheet; FIG. 7 shows the packaging seen in profile, after formation of the imposed breaking point, according to a first embodiment; FIG. 8 shows the packaging seen in profile; after formation of the imposed breaking point, according to a second embodiment; FIG. 9 shows, in a plan view, the packaging according to a third embodiment;

   FIG. 10 shows the packaging of FIG. 9, seen in profile, and FIG. 11 shows, seen in profile, the packaging according to a fourth embodiment.

  
Figures 1 and 2 show a section of a sheet 1 of embossed polyethylene, separated from a row or a continuous strip. This sheet 1 is advantageously translucent. It has a swirl chamber 2 to which is connected, by two channels

  
3 and 4, a compressible container 5 intended to receive the liquid. This container 5 is deeper than the swirl chamber 2 and than the channels 3 and 4, which accelerates the liquid inside the latter. In the first embodiment, a flat sheet 6, preferably an aluminum sheet, has a nozzle opening 7. At the time of assembly of the stamped sheet 1 and the flat sheet

  
6, following the arrows between figures 2 and 3, the opening 7 is aligned exactly with the center of the

  
swirl chamber 2. Between the container 5 and the swirl chamber 2 are provided the

  
two channels 3 and 4, offset by an angle of 180 [deg.] and opening tangentially into the chamber 2. The two channels may have a certain taper and narrow from the container 5, towards the chamber 2, of which the opening 7, according to figure 6 is closed

  
by a tab 27. The liquid is retained in the receptacle 5 by the air in the two channels

  
3 and 4. The latter have parallel sections 9, of generally constant cross section, the ends 10 of which are bent at approximately right angles, narrow sharply and open out tangentially.

  
in swirl chamber 2, at points

  
diametrically opposed to it.

  
Instead of the tongue 27, one can provide, between the channels 3 and 4 and the container 5, an imposed breaking point 8. In the region of point 8, one can provide, next to the container 5, an antechamber 11, in communication with the two channels 3 and 4, but separated, however, by the imposed breaking point 8 of the container

  
5, as long as the liquid is locked in

  
this one. To facilitate the separation at point 8, the container can be chamfered, as indicated at 12, in order to obtain a wedge effect at this point 8, when pressure is applied with the finger in the direction of arrow 13 of the Figure 6, and thus facilitate the separation of sheets 1 and 6.

  
In the exemplary embodiment of FIG. 7, the imposed breaking point 8 takes the form of an assembly 14 where a groove 17 formed in the stamped sheet 1 is glued at a point 16 of the flat sheet
6.

  
In the example of FIG. 8, the imposed breaking point 8 is obtained by making a deep embossing 15 after or during the assembly of the stamped sheet 1 with the flat sheet 6; a projecting rib 18 is thus formed in the sheet 6 which is in leaktight engagement with a re-entrant rib 19 of the stamped sheet.

  
In the example of Figures 9 and 10, the flat aluminum sheet 6 is covered by a thermoplastic sheet 20 of low thickness, a polyethylene sheet for example. These sheets of aluminum 6 and polyethylene 20 have no openings

  
and the nozzle opening 7 is formed at the same time as the stamping in the center of the swirl chamber 2. After filling the container 5 with liquid, the stamped polyethylene sheet 1, open at the top, is covered by aluminum foil 6, also coated with a thin foil

  
polyethylene 20, then the sheets are welded together under heat and pressure, so as to obtain a container closed on all sides for the liquid, while the whole system of channels 11, 9, 10 opens through the opening 7 in the swirl chamber 2. The assembly of the thin polyethylene sheet 20

  
with the flat sheet 6 of aluminum is, at least in the region of the imposed breaking point 8, of such a low resistance that by exerting a first pressure in the direction of arrow 13 on the container 5, the thin polyethylene foil 20 separates from aluminum foil 6 and opens in such a way that near the bevel 12 and the open breaking point 8, liquid can flow freely through the channels

  
3 and 4.

  
In the example of figure 11, the container

  
5 comprises two chambers, one of which 21 is completely filled with liquid, while another 22 still contains air in addition to another liquid. Between the two chambers 21 and 22, there is a partition 23 which breaks when the first pressure is applied to the chamber 21 in the direction of the arrow 13. The liquids of the two chambers 21 and 22 can thus be mixed inside. of the container 5. Another pressure then opens the breaking point 8 and by increasing it continuously, the mixture can be atomized by leaving the opening 7 of the nozzle.

  
The flat sheet 6 can also be made of a synthetic material such as PVC and be covered

  
of the thin sheet of polyethylene 20. Alternatively, the stamped sheet 1 and the flat sheet 6 can

  
be in one piece and the two sections can

  
advantageously be assembled by folding an edge along one of the long sides. After filling the container 5, the flat sheet section 6 can be folded over the stamped section 1 of the sheet.

  
The two sheet sections are then welded together one

  
to each other tightly.
