Improvements in Medicine Powder Packets.
A. communication to me from KONRAD TSCHANTER, of Beuthen, in the Empire
of Germany, Druggist.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, 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 and accompanying drawing, that is to say —
Paper packets or capsules are ordinarily used for the reception of small portions
of medicine powder of which the druggist has on hand always a number for
immediate use. In this state the capsule consists of a paper strip once folded
longitudinally which by folding the edges into one another is formed into a flat
paper packet open at the ends, as shewn in Figures 1 and 2 of the accompanying
drawing, which is in illustration of the invention.
a, a, is the folded edge of a paper strip and b, b, is the other edge, which is
formed by folding the edges into one another.
To fill a dose of medicinal powder into the paper, one end is closed by folding it
at the line c, c, against one side of the packet and is kept vertical by the fingers of
one hand, and the end above is opened by blowing into it or by using the finger
nails of the other hand.
Both methods have disadvantages, because blowing into the packet with warm
and damp breath, or touching the inside with the fingers militates against the
desirable hygienic and aesthetic condition. But by the present invention it is
possible to open the paper packet described without blowing or touching the inside
with the fingers. For this purpose the paper strip is folded in one or more places
in a longitudinal direction, which folds appear on the sides of the capsules after
the same are formed.
In Figures 3, 5, and 6, is represented a capsule with only one longitudinal side
fold d, d. By pressing the fingers against the flat packet at the sharp edges ca
and cb, the upper edges are separated as shewn in Figures 3 and 6. Through the
opening made in this way the powder is poured into the capsule, which is then
pressed flat and folded above in the same way as below, one end being then inserted
into the other. In this way the capsule containing the powder is finished
(Figure 8). Instead of a fold running the whole length of the capsule side a
short fold will be sufficient reaching from the upper end to a certain distance down
the side, as shewn in Figure 4, by the line d d¹. Both sides may be provided with
folds which may run from one end to the other, Figures 9 to 12, or one may
extend the full depth and the other only to a certain depth of the side, Figure 7,
or both folds may extend only to a certain depth of the side from above.
The folds are made in such manner that their hollow is inside the capsule and in
this way the sides belly out when both side edges ca, and c b, of the capsule are
pressed toward each other. If the folds described are omitted then by pressing
the side edges, the sides remain together in most cases, and the capsule is only bent
to one side, and the opening must then be effected by blowing, or with the finger
nails, as already described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
-
In medicine powder capsules the longitudinal folds on the side or sides, the

page_text: inner or hollow parts of which are on the inner side, so that by pressing the edges
together the sides above separate and bend outward, so that the capsule is thereby
opened, substantially as set forth and illustrated.
