that it can not be re?lled without distorting it.
The invention is illustrated in the accompany
ing drawing, in which Figure l is a side view of
a dispensing device made according to my in
20 vention. Figure 2 is a front view of. the dispens
ing device shown in Figure 1.‘ Figure 3 is a cen

2. Figure 4 is a section on line 4—4 in Figure 2.
Figure 5 is a detail section of the lower part of

it is returned to normal position by the spring 2|.
In operating this dispensing device it is held
in an upright position between thumb and mid
dle ?nger of the hand. The index ?nger is then 20
pressed down on the ?nger piece 20 and the
yielding support of the spring 2! is overcome.
The slide descends and carries the material con

The device is composed of a receptacle and a
tained in the cup Hi from the position shown in
Figure 3 to the position shown in Figure 5, where 25
it is discharged by gravity.
In Figure 6 is shown a dispensing device which
is non-re?llable. The rear part 26 of the slide
is provided with a slot 21. The headed screw or
rivet 28 is located ‘in the slot and as it is secured 30
slide, the receptacle being preferably made of
?rmly in the body of the device it acts to hold
material that is light in weight and that can be
the slide against removal and in addition it acts
to limit the movement of the slide.
Various changes can be made in the form and
molded, the b'akelite type being preferred. The
slide is preferably made of sheet metal.
35
The receptacle may be made of three pieces, a
body portion l0, and side pieces I I, all three held
together permanently by rivets I2.
The body portion is provided with a chamber
l3 for material M, the chamber being open at
40 the front and having an inclined bottom l5 to
direct material toward the front when the device
is held upright.
The side pieces II are provided each with a
groove I6 in line with the front of the‘ body por
45
tion I0. The slide l1 ?ts these opposed grooves
and forms the front of the chamber l3. The slide
‘ is normally ?ush at its bottom edge with the bot
tom of the chamber l3 and has a measuring cup
50 I8 of varying size and shape opening inwardly
into the chamber l3 and normally in position at
the bottom of the inclined bottom [5 of the cas
ing.
The casing has the ?at bottom face [9
across which the cup passes to wipe material
55 from the cup as it passes when pushed down thus
proportion of the parts without departing from 35
the scope of my invention.
I claim:
1. A dispensing device comprising a receptacle,
2. flat slide of sheet material forming the front
of the receptacle and slidable on the receptacle, 40
said slide bent over at the top, and a spring in
terposed between said top and the upper part of
the receptacle, the lower part of the slide having
a measuring cup open to the interior of the re
ceptacle when in normal position.
45
2. A dispensing device comprising a receptacle,
a slide of sheet material forming the front of
the receptacle and slidab-le on the receptacle, said
slide being bent over at the top, and then down
to engage the back of the receptacle to form a
50
housing, and a spring in said housing for yield
ingly holding the slide in normal position, said
slide having an inwardly opening measuring cup
positioned to be at the bottom of the interior of 55

the receptacle when the slide is in normal posi
tion.
3. A dispensing device comprising a receptacle
open at the front, a slide forming the front of
the receptacle and including a measuring cup
opening toward the receptacle, being normally
open to the interior of the receptacle and mov
able to a point beyond the receptacle, the slide
being bent over at the top to form a ?nger piece
10 and spaced from the receptacle to form a housing,
the receptacle having a recess in the back, the
end of the slide being bent into the recess to
form means for limiting the amount of move
ment of the slide, and a spring interposed be
15 tween the receptacle and the ?nger piece to
yieldingly hold the slide in normal position.
4. A dispensing device comprising a receptacle
having a body portion open at the front and hav
ing a bottom inclining toward the front, the body
portion having a recess on its back face, side
pieces secured to the body portion and extending
above the body portion and having grooves in line
with the front face of the body portion, a slide
in the grooves and forming the front of the re
ceptacle and having a cup opening into the re
ceptacle and normally at the bottom of the in
clined bottom of the receptacle, the slide being 10
bent over at the top and spaced from the body
portion and having its end bent into, the recess
of the body portion and a spring interposed be
tween the bent-over top of the slide and the top
of the body portion.
