SIPHON BOTTLE WITH GAS =.GENERAT OR Pierre Michel Eugene Deshayes, Paris, France Application December 7, 1951, Serial No. 260,506,

Claims priority, application France December 14, 195i) 4 Claims. (01. 2261-95121) The present invention relates to apparatuses for. gasifyingbeverages or other liquids; and the objects of the invention are to provide an apparatus improved with regard to the method of filling, the process of saturation with carbondioxide, the mannerofproducing and drawing off the gas, the preservation and fitting of the reagents for producing at the right moment the necessary amount of gas, and the composition, arrangement and location of the various parts of the apparatus.

Further features of the invention will be apparent in the ensuing description, reference being made to. the accompanying drawing given solely by way ofrexample.

Fig. l is an axialsection of a preferred form of a siphon bottle in accordance with the'invention.

Fig. 2 is aview thereof from below.

Fig. 3shows in axial section, a modification of the siphon bottle.

The apparatus as shown in Figs. 1 and 2 cornprises essentially a. container a of any convenient shape generally conical (as indicated) or cylindrical, ahead I), atube 0 depending from said headand a bottom :2, the latter being secured in a funnel h the open endof which is a short distance frormthe aforementioned tube 6, and a second tubea'jone endof which terminates near the bottom of the container.

Inside the generator ,1 is located a diffuserpunchdevice that comprises, punch element is of convenient shape and number, for instance arrow-headed rods, and a further punch device Z of different shape. The diffuser element of said diffuser-punch device may be for instance in the form of two superposedcircular plates m and m having a convenient number of holes of suitable size and shape. The aforementioned arrowheaded rods k are fixed to the plate in and the plate m. The punch device I isfixed to the plate in and is directed downward. Sufficient clearanceisleft betwe n t e plates nd and the inner-faceof the generator} to allow them to i 2 move freely longitudinally. A stop 0 is, provided to limit the inward travel of the plate. If desired, a filter, not shown in the, drawing, may be included between the opening; of the tube g in the generator f and the aforementioned diffuser elements;

As can be seen, the apparatus comprises two distinct capacities: a, container and a generator or reacting chamber entirely located inside said container and. communicating therewith only through the tubes 5/; and j. The chamber of the generator 1- is adapted to produce the correct amount of carbon dioxide gas-forsaturating the liquid in the container. by the reaction at the right moment in the presence of said liquid of suitable chemical products, preferably sodium bicarbonate and tartaricvor; citric acid.

The reagents may be introduced; mixed, and reacted in manydifferent; ways some of which are hereinafter described. In'this specific example, an intimatemixture of powdered and dry sodium bi carbonateand tartaric acid in proportions de-: pending on, the volume of the container is pre-,- paredin advance in a cylindrical water-tight cartridge y having a diameter slightly less than the generator). r T

The opening e may be closed by any suitable pressnreeresisting; water-tight seal. for instance a screw-plug, a-bayonet locking system combined with. a plug-Ora device comprising aplugp having a, packing q, fastening screw 1'; across-bar, t and hooks s, 3' (Figs. 1 and 2). The generator chamber may besealed in the same way. the plug 11' comprising, however in addition several small pushers stand a complementary punch devicelf The differentparts of the apparatus may be in any convenient material such as plastic or metal, and the. surfaces of all the internal parts are such as to, satisfy hygiene requirements.

The filling of the siphon bottle is performed in the following manner:

1 The bottleis held inverted in one hand-or on a suitable stand and the plugs 10 and p removed. After emptying and cleansing the, interior,a cartridge 21 containing the reagents is introduced 'intothe generator and by a gentle push the end 2.- thereof is pierced by the elements It fixed to the plate m. The piugp' is then placed intoposis tion, the pushers .9: thereof completing the perforation of the cartridge by'driving the cartridge still further along the arrow-headed rods is thereby causing said heads and the P1111011 ments .Z" to. pierce, the end 2', and thepunch elements Z, to piercethaupper end a, The described diffuser-p nch devices are so designed tha when the cartridge is inserted in the manner indicated practically noparticles of the reagents reach the liquid during the filling operation. To this end the holes relative to the plates m and m are in staggered relationship. After the plug 12' has been securely fixed, the liquid is poured through the tube piecee and passes through the funnel h and the tube g into the chamber of the generator f. The liquid also enters the container a through the space between the tube piece e and the funnel h, said space serving moreover as an air-outlet for the air escaping from the container during the filling operation. ,Therising level of the liquid progressively expels the air contained in the generator through the tube :i until the level of the end of said tube is attained. The liquid rises in the container up to the inner end of the tube piece 9 whereupon nofurther air is free to escape from the container and the filling operation is completed and the plug 1) is replaced. The

relative levels of the ends of the tubes 7' and e are .so arranged that the desired liquid-air ratio is obtained in the generator and in the container.

When the siphon bottle is returned to its nor mal upright position, the liquid contained in the generator passes downward, is diffused by the diffuser plates m and m, reaches the reagent cartridge, passes through the pierced holes on the side 2 and the tracks left in the reagents by the arrow-headed rods k and through. the open spaces between thepushers a: and thence through the pierced holes in the lower end .2. The gas is produced in abundance and rises in the nascent state through the tube :7, enters the container a and saturates the liquid. The diffuser plates m and m prevent any foam or liquid particles being carried upward by the gas.

To refill, the siphon'bottle is inverted, the plugs p and p removed, the generator emptied by tilting the bottle and allowing the diffuser-punch assembly to slide out carrying therewith the used cartridge that is detached and thrown away, the container and generator cleansed if necessary, and the procedure hereinbefore described is repeated.

The reagents contained in the cartridge may be mixed together in the solid state as hereinbefore referred to or entirely separate from each other, both in the solid state, or both in liquid solution (partially in suspension if desired), or one of them in the solid state and the other in liquid solution.

The apparatus may be constructed in such a way that the reacting liquid is directly poured into the generator, this may be so when the liquid to be saturated is not water but for instance wine, or water added to juices, syrups and the like.

Without departing from the scope of the invention, the reagents may be introduced into the generator in yet another manner, suitable devices being accordingly provided. For instance, the sodium bicarbonate and'the acid may be introduced separately in a single trough or in two separate troughs placed in the generator, or one of said products first poured into the liquid in the generator. Fig. 3 shows a generator comprising only the diffuser elements m and 111. without the punch devices, and a trough G in which the reagents are placed, said trough acting in the same manner as a perforated cartridge.

The siphon bottle in accordance with the invention possesses a considerable number of advantages over known types of siphon bottles.

Filling the bottle through the bottom avoidsunscrewing the head, taking off the depending tube and reassembling these parts. This construction may be of course employed in any kind of siphon bottle whatever be the saturating method and whether there be or not a reacting chamber. The bottle constructed in accordance with the invention is not only very easily filled but permits a perfect saturation of the liquid.

The generator position peculiar to this invention results in a siphon bottle in which the generator is fixed permanently and is entirely enclosed therein thus enabling the normal siphon bottle appearance to be preserved.

The correct amount of liquid is automatically introduced into the generator and container during the filling operation, as hereinbefore expiained, and requires no skill on the part of the user.

Another advantage is the use of an impervious cartridge which may be in any material easily punched, such as paper, metallic paper, a thin metal'tube (aluminium, tin-plated sheet, etc.), plastic, card board or a combination of said materials. This cartridge contains the correct proportion of reagents previously prepared, and the opening thereof at one end by means of the sealing plug and at the other by means of the diffuser punch device allows in combination with the action of the diffusers a regular downward flow of the liquid and upward passage of the gas produced. Owing to said device being freely slid able in the generator, the cartridge may be easily withdrawn by simply removing the plug p and allowing the cartridge to fall out. 7

It is obvious that a siphon bottle in accordance with the invention presents important advan+ tages over known apparatuses of the type in which saturation is obtained by means of individual charges, namely siphon bottles employing bulbs generally made in steel containing highly compressed liquefied gas, and generally adapted to be reloaded due to their high cost price. 1

In the siphon bottle in accordance with the invention there occurs a progressive saturation instead of a Wild discharge of highly compressed gas, thegas is chemically pure and exhibits the well-known characteristicsof the nascent state, as opposed to the preserved industrial 'carbon dioxide that has frequently an unpleasant taste. The inexpensive cartridge packing may be thrown away after use. There is no risk of the packing exploding as is the case with known 7 types of bulbs,neither is there the slightest risk r bulb charges. 1

The invention is not limited to details of construction hereinbefore set forth and illustrated, which have been given merely by way of example;
