I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
Southampton Buildings, 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:-
This invention relates to an improved receptacle for dry powders which are required
to be used from time to time in small quantities, and more especially for tooth powders.
It has for its object to provide a cheap, convenient case in which the powder may be
very closely packed or compressed into a nearly solid mass and from which it may be
readily discharged in small quantities and in loose form without removing the
covering lid and without danger of spilling; and also to provide a definite measure.
for the powder in combination with the lid and means whereby the loosened powder
may be readily transferred to a tooth brush, if desired, without affecting the mass.
It consists in the combination with a suitable cylindrical case, preferably made of
paper, of a metallic disc or follower fitting within the case to serve as a lid or
protecting cover for its contents, and which is perforated with one or more slits or
openings having cutting edges adapted to loosen the pulverulent material in the
box when revolved in contact therewith so that the material may drop through the
openings and in the combination with said disc of a receptacle formed thereon to
serve as a measure for the powder which works out through its perforations, and of
parallel plates projecting from the disc, to serve as ears by which to revolve it and
as guides between which a tooth-brush may be inserted to receive the powder
dropping therefrom.
It consists also in the combination with said case and its follower of an outer
auxiliary cover to fit over the end of the case and which is provided with internal
lugs or offsets to engage the ears projecting from the disc and thereby lock the

page_text: disc to the cover so that a revolution of the latter shall turn the former, and of a
receptacle within the cover into which the loose powder dropping from the revolving
disc of the follower may be collected in readiness for application to a tooth-brush
or for other purposes.
a tooth
It consists moreover in the combination with said outer or auxiliary cover of an
outer receptacle for soap, vaseline or other cosmetics and in the combination with the
body of the case of a loose encircling band provided with a clip for holding
brush and with an elastic cutter to cut off the superfluous end of the case as it becomes
emptied.
In the accompanying drawings.

powders, when made in its simplest form without auxiliary cover.
Figure 2 is a view in perspective of a cover for the same with combined soap,
pomade or vaseline receptacle.
Figure 3 is a central longitudinal section of the case and its auxiliary cover
combined.

illustrating a modification in form of the openings in bottom of the follower.
A represents the cylindrical case, which is preferably made of paper, card-board or
very thin metal to admit of being readily cut away and reduced in length as it is
gradually emptied, but which may also be made of celluloid or rubber or other stiff
material in more permanent form.
This case admits of being ornamented in various ways as good taste may suggest.
It is preferably encircled by a metallic band B. If the case be made of paper or
other comparatively weak material, this band is made loose enough to admit of
being moved along the case and is fitted with a lateral spring C terminating in a
cutting blade made to project over the upper edge of the band in position to admit
of being pressed inward against the periphery of the case. By pressing the blade
inward and revolving the band, the case will be cut apart circumferentially with a
clean cut.
.
A cup-shaped follower consisting of an annular plate D of a diameter small enough
to fit loosely within the case and whose inner end is closed by a disc E, is provided
to serve as a lid to cover the contents of the case. Preferably two circumferential
ribs or bands f, f, are formed upon the outer periphery of the follower at its upper
and lower edges to fit closely and accurately within the case the annular recess
between the bands serving to catch any material which may work past the inner
band in the use of the device, and to reduce friction between the follower and
the case.
This follower or movable lid for the case is designed to remain therein until the case
is emptied of its contents. To facilitate this end, one or more transverse openings
having cutting edges g, g, see Figures 3 and 4 are made in the disc E; or the disc is
perforated with holes h, h, h, see Figuro 5 laving ragged edges on the under side, the
function of said cutting or ragged edges being to scrape or stir up the under-lying
material whenever the disc is rotated and thereby promote a discharge thereof into the
follower through the apertures in the disc.
A central compartment is preferably formed within this cup-shaped lid or follower 1)
by means of two parallel partition plates 1, I, secured thereon at a distance apart
corresponding substantially to the width of a tooth-brush and which project beyond
the outer rim of the follower far enough to allow of the insertion of the head of a
tooth-brush between them. Where those plates are used, the openings in the disc E
are confined to the space included between said plates so that the discharge from the
case shall be made only into said compartment.
By making this compartment of a determinate size it can be used as a measure
of the quantity of material discharged therein from the case.
The projecting ends of the plates I, I, serve conveniently as ears or handles by
which to revolve the follower.

page_text: In the use of the device in its simple form as described the case A is closely packed
with tooth powder or other pulverulent material, leaving space enough only at the
outer end to permit of the insertion of the follower D so that its disc E shall rest upon
the surface of the powder and serve as a cover therefor.
By revolving the disc by means of the projecting plates I, I, the cutting edges of
the slits g, (or the equivalent ragged edges of the holes, h) will operate to scrape
or shear off more or less of the powder from the surface of the tightly packed mass in
the case, and the loosened powder will work up through the openings in disc between
the plates I, I, into the central compartment of the follower, so that, by inserting
tooth-brush between said plates and then reversing the case, the powder will fall upon
the brush.
EL
In this manner a sufficient quantity of powder may be neatly applied to a wet
brush without spilling it and without wetting the powder in the case, so that the same
case may be used in connection with different tooth-brushes without objection. As
the follower need not be removed from the case, the powder within the case is con-
stantly protected from the air and dust as well as from contact with the brush.
When, by the withdrawal of a quantity of powder, the follower passes so far down
as to render it inconvenient to fit a brush between the plates I, I, the band B is
slipped up so as to bring the cutting blade C into position near the outer end of the
case, whereupon by rotating the band and pressing in the cutter, a portion of the end
of the case may be neatly detached and removed.
When the case is used for medicinal or other powders, other than for the teeth, the
form of the plates 1, I may be modified and the central compartment, or the entire
interior of the follower, be used simply as a receptacle, and, if desired as a determinate
measure for the amount of powder to be taken from the case at any one time.
An outer cap K may be fitted over the end of the case to embrace the projecting
plates or ears I, I, and to serve as a cover for the follower.
The render the device more complete where an outer auxiliary cap or cover K. is
used, I form within said cover offsets or lugs L, L, to engage the ends of the ears or
plates I, I, projecting within the cover, so that by revolving the cover K, the
follower D will be made to revolve with it; and I form or secure also within said case
a central diametric receptacle M, adapted to fit neatly in over the central compart-
ment of the follower between the plates or ears I, I, when the cap is placed upon the
case. Hence by inverting the case as shown in figure 3 and then holding the cover K
and revolving the case, the powder loosened by the cutting edges g, g, will drop into
the receptacle M of the cover.
To prevent the follower from being drawn out by the suction produced in removing
the cover K, small air holes s, s, are pierced in the cover outside of its joint with the
case, as shown in Figure 3.
This receptacle M in the cover, when charged with a sufficient quantity of powder,
is admirably adapted to permit of dipping a tooth brush therein to take up the
powder. As the receptacle is readily emptied and cleaned after being thus used and
as readily freshly charged for use again, it may be used by different persons without
objection.
The device is rendered yet more complete by forming in the outer end of the cap
or cover a receptacle N, for toothsoap, vaseline, cosmetics or such other preparations
as may be desired, said receptacle being preferably closed by a cover O screwing
down therein as shown in Figure 3.
A ring P is attached to the band B by which to hang up the case and for tooth
powder cases a clip R is fixed to the opposite side of the band by which a tooth-
brush may be suspended from the case.
It is evident that the proportions and dimensions of the case A may be greatly
varied without departing from my invention.
Also that ears or arms for revolving the follower may be made to project from the
auxiliary cover to engage lugs or offsets upon the follower, as an equivalent for the
cars or plates I, I, projecting from the follower.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondents I declare that what I claim is :-
First. The combination, substantially as herein set forth, of the cylindrical case, a
perforated follower fitting within said case, and arms or plates projecting outwardly
from the follower to facilitate revolving the same.
Second. The combination, substantially as herein set forth, of the cylindrical case,
a perforated follower fitting within said case, arms or plates projecting outwardly from
the follower to facilitate revolving it, a band encircling the case and turning freely
thereon, and a spring cutter carried by the band and adapted to engage and cut the
case wlien pressed inward.
Third. The combination, substantially as herein set forth of the cylindrical case, a
follower fitting within said case, a receptacle upon the outer face thereof communi-
,cating with the interior of the case through one or more openings in the follower,
and parallel guide plates forming two sides of said receptacle and projecting out-
wardly substantially as set forth.
Fourth. The combination of the cylindrical case, a perforated follower fitted within
the same, a receptacle formed on the outer side of the follower to communicate
through its perforations with the interior of the case, an auxiliary cover fitting over
the outer end of the case, interposed arms or plates projecting from the one to engage
lugs or offsets on the other so that a revolution of the cover shall cause the follower
to revolve, and a receptacle in said cover made to register with the receptacle on the
follower, substantially in the manner and for the purpose herein set forth.
