This invention relates to paste dispensers espe- and includes substantially rectangular-shaped
\cially adapted for dispensing dental, shaving or end plates 9 connected by, rods l0 andv also having
facial creams without soiling the hands of the
user and-has for the primary object the pro5 vision of an efficient, durable and inexpensive
device of this character which will support and
journaled in openings thereof a shaft II, one
end of which extends through the slot 1. The
extended end of the shaft has a ?nger piece I2 6
secured thereto. The shape of the plates 9 of the

Referring in detail to the drawing, the numeral I indicates a casing having secured to its
rear wall one of the sections of a wall clamp
2 while the other section of the clamp is fas-
slightly larger than the interior diameter of the
sleeve 19 so that said sleeve tightly ?ts the ball
and thereby forms a valve closure for the neck
5 of the tube 6. The ball 20 is mounted on a 35
rod 2| and the latter is secured to the ?ange I8
of the sleeve I!) by a cross rod 22. When pres
sure is applied to the contents of the tube, the
contents expands the sleeve l9 and passes about

the casing will be supported in a vertical position. The bottom of the casing is in the form
of a removable closure 3 held on the casing by
soon as the pressure is released on the tube the
sleeve l9 contracts against the ball so as to close
the contents of the container against atmospheric

has an opening to permit a discharge neck 5 of
a collapsible tube 6 to extend therethrough when
said tube is arranged in the casing in an in;

A side wall of the casing has formed therein a
slot 1 which opens outwardly through the‘ lower
end of the casing and is normally closed at said

Figure 6, a type as Shown in Figure '7 may be 6m
ployed and consists of a valve housing 23 having
a bore 24 extending therethrough and a por

When either of the valves, as shown in Figures
6 and 7 is applied to the neck of the tube 6. it will
prevent said tube from becoming disarranged in
the casing I and provides a simple means which
will permit the easy removal and replacement'of
a tube in the casing when desired.
What is claimed is:
10
l. A' paste dispenser comprising a vertically
arranged casing having a removable bottom pro
vided with an opening to receive a neck of a
collapsible tube with the vlatter arranged in an‘
inverted position within said casing, a frame slid
15
able in said casing, said casing having a slot,
spaced cushion rollers carried by said frame
and receiving therebetween the tube, a shaft jour
naled in said frame and extending through the
slot and having a slot to receive one end of the
tube, a ?nger piece secured to said shaft where
by the tube may be wound on the shaft to bring
about expelling of the co tents of the tube by
the rollers, a valve housing threaded onto the.
25 ' neck and against the cover and having a seat, an
elastic sleeve extending out of said valve housing
and having a ?ange to engage the seat, and a
-
ball supported in the sleeve and of a diameter
slightly greater than the interior diameter of the
sleeve.
2. A paste dispenser comprising a vertically
arranged casing having a removable bottom pro
vided with an opening to receive a neck of a _ 5
collapsible tube with the latter arranged in an
inverted position within said casing, a frame
slidable in said casing, said casing having a slot, _
spaced cushion rollers carried by said frame and
receiving therebetween the tube, a shaft jour 10
naled in said frame and extending through the
slot and having a slot to receive one‘end of the
tube, a finger piece secured to said shaft where
by the tube may be wound on the shaft to bring
about expelling of the contents of the tube by
the rollers, a valve housing threaded onto the
neck and against the cover and having a seat,'
an elastic sleeve extending out of said valve
housing and having a ?ange to engage the seat, 20
a valve housing threaded on the neck against the
cover and having a bore therethrough, a valve
element for opening and closing the bore and
journaled in said valve housing, and a ?nger piece
secured‘to said valve element.
