Abstract

A portable container for liquids, such as drinks, has its own heat source. An inner vessel (2) is sealed inside an outer container (1) by welding to its bottom. A vent slot (A) communicates to atmosphere. The cartridge (3), containing the heat source, fits inside the inner vessel (2) and is provided with six gas holes. When pressure is applied at a marked spot, a chemical reaction occurs, heating the liquid in the surrounding outer container, which can then be poured out from the spout (4). The gases generated are exhausted through the base slot.

Description

       

  "Dispositif pour chauffer des liquides, plus particulièrement

  
des boissons, et récipient renfermant un tel dispositif"

  
 <EMI ID=1.1> 

  
pour chauffer des liquides, plus particulièrement des boissons,

  
et notamment du café. Ce récipient comprend un dispositif

  
intérieur assurant une réaction chimique, et il est désigné

  
dans son ensemble sur la figure annexée par la référence 1,

  
ce récipient étant destiné à contenir une dose assez concentrée

  
de café liquide sucré, prêt à être bu, ou d'autres boissons analogues, et se chauffant au moment de l'usage.

  
Ce dispositif est composé de tubes désignés sur la figure annexée par les références 2 et 3. Le tube 2 est au fond

  
fixé de manière étanche , par exemple soudé,/du récipient 1,

  
tout en laissant une petite fente de communication avec l'ex.,té-rieur pour le dégagement éventuel de gaz, cette fente étant désignée par la référence A. Le tube 2 contient à l'intérieur le tube correspondant 3, où sa produit la réaction entre substances chimiques qui réagissent à la suite de l'établissement d'une pression au point indiqué dans ce but sur l'extérieur du récipient.

  
Ce tube 3 est fermé aux deux extrémités et il est garni de six petits trous, dont trois d'un côté et trois de

  
 <EMI ID=2.1> 

  
les gaz qui ne réussissent pas à se condenser pendant la réaction pour passer ensuite dans le tube 2 et pour être évacués à l'extérieur par la petite fente A du fond, comme susdit, ce qui évite d'inutiles pressions internes.

  
Le dispositif de réaction est complètement isolé

  
du café qui reçoit seulement de la chaleur.

  
La présente invention a également pour objet un dispositif pour chauffer des liquides, en particulier des boissons, analogue au dispositif intérieur du récipient, décrit ci-dessus, mais considéré indépendamment, en vue de l'utiliser seul.

  
 <EMI ID=3.1> 

  
primer un instant le récipient de l'extérieur au point indiqué à cet effet sur le récipient et en quelques secondes le café est chauffé jusqu'à 60[deg.] et plus.

  
Les substances chimiques réactives sont de volume

  
et de poids insignifiants, inodores et tout à fait inoffensives, parce qu'elles sont à base de Al et de chlorure ferrique.

  
Les gaz qui se produisent se décomposent pendant la réaction et restent difficilement des résidus.

  
Pour pouvoir obtenir une fermeture hermétique du récipient décrit précédemment et pouvoir ouvrir facilement

  
ce dernier au moment de se servir, au sommet de l'ouverture, désigné par la référence 4, on a introduit une petite bande de tissu ou d'une autre matière poreuse et résistance, laquelle est comprimée et soudée à chaud sur environ 3 mm de hauteur.

  
De cette façon, la matière plastique fond à la chaleur et

  
est absorbée très fort entre les pores de la bande même,

  
ce qui produit une fermeture hermétique.

  
Tirée de l'extérieur, la bande précitée déchire facilement la matière plastique au point d'absorption, ce qui laisse le trou libre.

  
Il doit être entendu que la présente invention n'est en aucune façon limitée à la forme de réalisation décrite ci-dessus et que bien des modifications peuvent y être apportées sans sortir du cadre du présent brevet.

REVENDICATIONS

  
1. Récipient pour chauffer des liquides, plus particulièrement des boissons, caractérisé en ce qu'il comprend

  
un dispositif intérieur assurant une réaction chimique, en vue d'obtenir un chauffage régulier et rapide du liquide dans tout le volume du récipient, avec un meilleur fonctionnement et une productivité technologique très éconoroque.



  "Device for heating liquids, more particularly

  
drinks, and a container containing such a device "

  
 <EMI ID = 1.1>

  
for heating liquids, especially drinks,

  
and especially coffee. This container includes a device

  
interior ensuring a chemical reaction, and it is designated

  
as a whole in the figure appended by reference 1,

  
this container being intended to contain a fairly concentrated dose

  
sweetened liquid coffee, ready to be drunk, or other similar beverages, and heated at the time of use.

  
This device is composed of tubes designated in the accompanying figure by the references 2 and 3. The tube 2 is at the bottom

  
sealed, e.g. welded, / of the container 1,

  
while leaving a small communication slot with the ex., front for the possible release of gas, this slot being designated by the reference A. The tube 2 contains inside the corresponding tube 3, where its product reaction between chemicals which react as a result of the building up of pressure at the point indicated for this purpose on the outside of the container.

  
This tube 3 is closed at both ends and it is lined with six small holes, three of which on one side and three of

  
 <EMI ID = 2.1>

  
the gases which do not succeed in condensing during the reaction to then pass into the tube 2 and to be evacuated outside through the small slit A at the bottom, as aforesaid, which avoids unnecessary internal pressures.

  
The reaction device is completely isolated

  
coffee that receives only heat.

  
The present invention also relates to a device for heating liquids, in particular drinks, similar to the internal device of the container, described above, but considered independently, with a view to using it alone.

  
 <EMI ID = 3.1>

  
Prime the container for a moment from the outside at the point indicated for this purpose on the container and in a few seconds the coffee is heated to 60 [deg.] and more.

  
Reactive chemicals are bulk

  
and of insignificant weight, odorless and quite harmless, because they are based on Al and ferric chloride.

  
The gases produced decompose during the reaction and hardly remain residues.

  
To be able to obtain a hermetic closure of the container described above and to be able to open easily

  
the latter at the time of use, at the top of the opening, designated by the reference 4, a small strip of fabric or of another porous and resistant material has been introduced, which is compressed and heat-welded on approximately 3 mm height.

  
In this way, the plastic melts in the heat and

  
is absorbed very strongly between the pores of the same strip,

  
which produces an airtight seal.

  
Pulled from the outside, the aforementioned tape easily tears the plastic material at the point of absorption, leaving the hole free.

  
It should be understood that the present invention is in no way limited to the embodiment described above and that many modifications can be made to it without departing from the scope of the present patent.
