CLOSURE FOR C‘OLLAPSIBLE TUBES
Adolph Heisman, New York, N. Y.
Application January 12, 1934, Serial No. ‘706,324
8 Claims. (01. 221-60)
This invention relates to new and useful im
provements in closures for tubular elements such
as collapsible tubes employed in the use of
powdered or pasty material such as dentifrice
5 altho the device may be employed with any con
tainer to control the discharge of material there
from.
An object of the invention is to provide a simple
slide means for controlling the opening and
10 closing of the entrance to the tube.
A further object is to provide a simple latch
means which acts as an operating element to
move the slide plate and provided with cooperat
ing means whereby its position in certain posi
15 tions of the slide plate is limited.
A further object of the invention is to provide
a simple, compact and durable unit which may be
manufactured separate from the tube if desired
H and applied thereto as a unit in any suitable
20 manner such as by welding, screwing, soldering
and the like.
Further and more speci?c objects, features and
advantages will more clearly appear from a con
sideration of the speci?cation hereinafter set
25 forth when taken in connection with the accom
panying drawings which form part of the speci
?cation and which illustrate present preferred
forms of the invention.
_ ‘
Brie?y and broadly considered, the invention
30 includes a base member which can be suitably
fastened on to the breast of a container such as
a tube of tooth paste. This base has an aper
tured neck and a lateral extension thereon.
The aperture in the neck is opened and closed
35‘ by means of a slide plate movable back and forth
in suitable grooves in the side walls of the base.
the tube.
In one form of the invention the latch
bar is one element on the cap plate or bar and in
another form of the invention the latch element
is formed by a plurality of ?ngers extending from
the rear of the cap plate or bar.

As shown in the drawings the invention is
adapted to be applied to the upper end of a
collapsible or other form of tube [0 which may 30
contain any material such as tooth paste or the
like. This tube maybe provided with a breast
ll.
'
The device comprising the invention herein has
a base or body portion comprising a neck [2 with 35
a lateral extension l2’. This neck has an aper
ture l3 therein disposed over the aperture [4 in
the breast ll, whereby the material in the tube
Ill may pass outward through these two apertures.
The sides of this neck and extension are pro- 40
vided with over-hung shoulders I5 and with a
depression IS on the top surface of the neck and
position to open the tube then the cap plate or bar 1 extension just back of the aperture I3.
A slide plate, I‘! rests on the top of the neck and
has to be ?rst swung up and back and then the
extension
and has outwardly extending over- 4!,
slide plate can be moved to open position. When
in this position the cap plate or bar cannot be turned edges 18 which pass around and under the
The slide plate is movable by contact of the ?ngers
of the operator with an operating bar or cap plate
, pivoted to the slide plate and adapted when the
‘10 slide plate is in closed position to be swung forward
to a closed position over the outer end of the
slide plate. When the slide plate is moved to the
4
swung to closed position because means such as
?ngers thereon lie close adjacent to walls of the
‘ base or a central overhanging latch or stop bar
50 to'preventthis premature movement of the cap
plate or bar.
The slide is also provided with suitable tits to
cooperate with recesses in the base to latch the
7 plate in its forward or closed position thus as
5
sisting in the- retention of the slide plate to close
shoulders or edges 15 so as to clamp‘ the slide
plate I‘! ?rmly and yet slidably in place on top of
the neck l2 and extension l2’. At the rear of the
plate I‘! are upwardly extending ears forming 50
journals I9 for a shaft 20. This shaft 20 acts as
a pivot for a cover plate 2| which has rearward
integral eyes 2|’ embracing the shaft 20. The
cover plate 2| has a forward face 22 which is
slightly bent to snap over the front edge of the 55
2
2,038,130
neck I 2 when in the closed position shown in Fig.
3. The cap plate 21 is also provided with a lining
10
15
20
25
30
of cork 23 or similar material to protect the cover
from the paste material which may issue from
the tube In.
The cover plate 2| also is provided with a cen
tral rearwardly extending latch ?nger or element
24 with its outer edge slightly bent as shown in
Figs. 3 and 4. When the cover plate 2| is in the
closed position shown in Fig. 3, this bent edge lies
just within and below the edge of the depression
16 and prevents the cover plate 2| from being
moved longitudinally rearward until it is swung
up and back to the position shown in Fig. 4. It
will be observed that when the cover plate 2| is
to be moved from the closed to the open position
the latch element 24 will swing downwardly into
the depression I6 and then will assume the posi
tion shown in Fig. 4. But when the slide plate I ‘I
is then pulled back to open the aperture l3 the
latch element 24 is then lying on top of the surface
of the neck l2 and extension l2’ and can not
be moved to its closed position at least until the
slide plate has been moved back to the position
shown in Fig. 4. This then provides a suflicient
and effective bar to the cover plate being closed
until the other parts are in the proper position
for such an action to take place. This device is
simple and economical to make and is ef?cient in
operation and of relatively few parts.
As shown in Figs. 5 to 8 the device comprising
this form of the invention has a base comprising
neck I2 with extension I 2’ which can be fastened
to the breast II in any desired manner. This
35 neck has an aperture I 3 therein disposed over the
that the rear under face of the slide plate I‘! is
provided with a tit 3| adapted, when the plate
is in its closed position to lie in a recess 32 in the
bottom wall of the neck I 2 so as to hold or latch
the plate in this closed position.
In the form shown in Fig. 9 the cap plate 28 is
omitted and the latch arm 29 is operated by means
of a simple arm or handle bar 33 which is, how
ever, pivotally connected to the slide plate I‘!
as above described for the cap plate 28.
10
In the form of the invention shown in Figs. 10
to 13, the rear of the slide plate I‘! is provided
with a sleeve-like journal element 34 to receive the
?ngers 35 on the rear of the cap plate 28. This
cap plate 28, instead of having the rearwardly 15
extending central latch arm 29 as in the forms
shown in Figs. 5 to 9 inclusive, has a pair of latch
arms such as 36, extending back from the rear of
the sides of the cap plate 28 and adapted when
the plate is in the position shown in Fig. 10 to lie
housed in a sort of recess such as 31 formed in
the side walls of the neck l2 and extension l2’.
When the slide plate I1 is drawn back and the
cap plate is in the position shown in Fig. 13, then
the latch arms 36 lie over the top of the side walls 25
of the neck [2 and extension I2’ and prevent the
cap plate from being swung up and over until
the slide plate IT is moved forwardly to the clos
ing position again.
It will thus be seen that the invention provides 30
a simple, eflicient and useful construction adapted
to cooperate with the neck of a tubular member
to control the discharge of material therefrom.
The closure means may be operated by the ?ngers
of the same hand that holds the tube of material.
aperture [4 in the breast l l whereby the material
To open the tube the ?nger merely ?ips back
in the tube may pass outward through these two
the cap plate or the cap bar or handle and then
apertures.
The upper side walls of the neck l2 and ex
40. tension l2’ in this form are provided with longi
tudinally extending slots such as 25, (see Figs. 8
and 9) adapted to act as guideways for a closure
plate I’! which slides back and forth therein. In
one position of this plate l'l it is disposed to close
45.
the opening l3 to prevent the discharge of material
and in another position thereof it acts to permit
the discharge of the material since it is then
drawn back so as not to cover the aperture 13.
The rear of the plate I‘! is provided with up
turned ears 2B in the form shown in Figs. 5 to 9
inclusive. These act as pivots or journals for the
inwardly turned ?ngers 2'! disposed on the rear
of the operating cap plate 28. By grasping this
55 cap plate, the slide plate I‘! can be moved back
and forth as desired. When the device is in
closed position the cap plate 28 is disposed in its
forwardly bent position as shown in Figs. 5 to 7,
50
and acts as an additional cover. When in this
60 forward position the cap plate 28 may be latched
therein by reason of the provision on the rear
edge thereof of the latch arm 29 which, as shown
in Fig. 7, is adapted to lie under the arm 30 ex
tending from the rear of the top of the neck [2
65 and extension 12' in a forward direction.
When the cap plate 28 is swung upward and
backward, then the slide plate I‘! can be moved
to the rear to expose the aperture l3 and permit
the discharge of the material. When in the rear
70 ward position as shown in Fig. 8, the cap plate
28 can not be swung over to its closed position
because then the latch arm 29 is lying closely over
the latch bar 30 which prevents such a movement
of the cap plate 28 which is really the operating
75 element for the device. It will also be noticed
pushes the slide plate backward until the aper
ture I3 is exposed whereupon the material can
be discharged either by spilling it from the tube 40
or by forcing it out by collapsing the tube if of
soft metal. When the cap plate or bar is turned
back and the slide plate is moved back, the cap
plate or the bar cannot be swung over to closed
position because of the ?ngers 36, or the latch bar
29, or the latch elements 24 depending upon which
form of the invention is being employed.
The operation and use of this device in connec
tion with tubes permits the material to be better
preserved and kept, from deleterious contact with
dirt dust and the air which would tend to dam
age it. It also avoids the condition where the
ordinary cap is lost and the neck of the tube
is left constantly open.
While the invention has been described in de
tail and with respect to a present preferred form
or forms thereof, it is not to be limited to such
details and forms since many changes and modi
?cations may be made in the invention without
departing from the spirit and scope of the inven
tion in its broadest aspects. Hence it is desired
to cover any and all forms and modi?cations of
the invention which may come within the lan
