Gases.
I, HEINRICH KORRODI, Engineer, of 6, Archivstrasse, Berne, in the Republic
of Switzerland, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This invention relates to an improvement in capsules for compressed or liquified
gases, which are intended, after being perforated, to be introduced into a receptacle
containing liquid, in order that the liquid in the receptacle may be saturated
with gas. The invention consists in the combination with the capsule itself of
a pricker or perforating apparatus, by means of which, through pressure applied
from without to the outwardly projecting stem of the perforator a covering plate
of the case, which is made of some soft material, can be easily pierced through.
In the accompanying drawing two forms of this capsule, fitted with the new
apparatus, and intended for compressed, or liquified gases, are illustrated in
section.
The capsule a in Fig. 1 has an outer cover b, preferably made of some hard
metal, for example, of metal similar to the capsule itself, and an inner cover o
made of some soft material, such as sheet tin, sheet aluminium, or the like. Both
covers are tightly pressed by means of the turned in edge of the capsule neck,
against the inner shoulder d of such neck, the inner soft cover c serving at the
same time as a means of tightening. In a recess of the outer cover b, a suitably
formed perforator e is arranged, the stem of which is carried into the outer cover
and projects therefrom, so that, by means of pressure or of a blow applied to the
stem, the perforator e is caused to penetrate the inner soft cover c of the capsule a,
whereby the gas is enabled to pass through the hole thus formed. In order to
facilitate the escape of the gas through the outer cover b, small outlets f are
provided, or the hole in which the stem e is guided is made sufficiently wide
for the purpose.
In the form represented in Fig. 2, a further cover g made of some hard material
is placed below the soft inner cover c, and has a small hole h, which regulates
the outflow of the gases after the soft cover c has been perforated,

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
Improvement in capsules for compressed or liquified gases, to be introduced
into liquids, for saturating the same with gases, consisting in the arrangement
of a perforator, between the inner soft metal cover of the capsule and the outer
cover of the same, for the purpose of perforating the first-named cover, the stem
of which perforator is guided in the outer cover and projects therefrom, for the
purpose of effecting the perforation of the soft cover, by means of pressure, or
of a blow, applied to such stem, and thereby enabling the gas to pass out.
Dated this 19th day of September 1899.
