Description

Patented J... 13, 1925.
JOHANNES FBENG AND EINAR BERGVE, OF CHRISTIANIA, NORWAY.
METHOD FOR PRODUCING A No Drawing.
To all whom it may concern:
Be it known that we, J OHANNES FRENG and EINAR BERGVE, both subjects of the King of Norway, and both residing at Christiania, Norway, have invented certain new and useful Improvements in Methods for Producing a Disinfecting or Cleansing Spray for Hygienic and Medical Purposes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
This invention has for its object the method of producing a liquid dentifrice. A characteristic feature of the invention is the impregnation of an aqueous solution that forms the base of the dentifrice with carbonic acid. The pressure should be at least three atmospheres.
It is known to effect the cleansing or disinfection of the teeth and of the month by means of atomiz ers. attained an extended use by dentists and physicians. In these known atomizers a liquid disinfectant is atomized by means of air under a pressure of about 5 atmospheres.
According to the present invention an improved effect of the liquid dentifrice is obtained by impregnating the cleansing or disinfecting liquid with carbonic acid immediately before it is applied. This impregnation is suitably brought about by atomizing the liquid by means of carbonic acid gas or gas rich in carbonic acid instead of using air for this purpose. To increase the carbonic acid content of the atomized liquid it may also be suitable to pass a current of gaseous carbonic acid under pressure through the liquid previously to its being atomized by the carbonic acid gas. The atomizing as well as the impregnation may be effected by means of pure carbonic acid or by means of a gas rich in carbonic acid; for instance, a mixture of carbonic acid and air containing 30 per cent' of CO has been found to be very suitable. Instead of using a mixture of carbonic acid andair it may be suitable in some instances to employ pure nitrogen or pure oxygen as an admixture.

Such atomizers have- DISINFECTING OR CLEANSING SPRAY FOR HYGIENIC AND MEDICAL PURPOSES.
1920. Serial No. 379,597.
The carbonic acid may be obtained from i any suitable source and the required pressure may be created therein by different means. Thus the carbonic acid may be produced by the action of an acid upon carbonate of lime or other carbonate.
Commercial liquid carbonic acid in steel flasks may also be employed. In this case it will be of advantage to fill .the liquid carbonic acid into small flasks of such a size as to allow of being easily carried by the hand. The flask may, for example contain about 2 to 5 kilogrammes. These flasks may then-be connected with the atomizer through pipes provided with pressure controlling means. As long as liquid carbonic acid is contained in the flask a constant pressure is maintained, viz., at ordinary temperature about 40-50 atmospheres. By the strong evaporation which takes place when the valve is opened solid carbonic acid may be produced which may obstruct the capillar boring of the atomizer nozzle. This di ficulty may be avoided by the insertion of an electric heat element. The atomizer nozzle employed may be constructed according I to known principles.
The cleansing or disinfecting liquid becomes atomized in the nozzle by the action of the compressed gas current and is mixed with air until the desired velocity is attained. In a usual dentifrice atomizer about 1 liter of carbonic acid gas (of atmospheric pressure) will be consumed to wash the Y teeth one time. When the concentration of} carbonic acid dissolved in the sprayed liquid is suificiently high the spray besides'having stances. Thus to dissolve this deposit thewhich thus comes to action in status nasdentifrice must show a suflicient acidity but at the same time the dentifrice must not act too strongly upon the mucous membranes of the mouth.
The applicants have now found that these requirements are fulfilled by the carbonic acid. It has been found however that to attain a sufficiently strong dissolving action the liquid to be atomized should be impregmated with carbonic acid under pressure before it is atomized so that a solution saturated with carbonic acid at a superatmospherical pressure is produced. This may be attained by placing the pipe, through which compressed carbonic acid is conveyed to the atomizer by means of two channels, in communication with the bottom and top portions of a bottle containing the liquid to be atomized so as to cause the carbonic acid gas to bubble through the liquid. To avoid a too rapid escapeof carbonic acid when the pressure is relieved the viscosity of the liquid may be increased by suitable additions such as for example glycerin.
hen liquid containing perborates is treated with carbonic acid under pressure as above described the carbonic acid will react upon the perborate so .as to produce hydrogen peroxide or oxygen respectively,

2. Method for the production of a cleansing and disinfecting spray which consists in impregnating a liquid dentifrice containing a perborate with carbonic acid gas, and thereupon atomizing the impregnated liquid by means of a high pressure carbonic acid as. i
3. Method for the production of a dental spray, which comprises spraying a liquid dentifrice capable of splitting off oxygen, by means of carbon di-oxide and also dissolved in the dentifrice to cause the solution of tartar and the liberation of oxygen as an antiseptic.
