CLOSURE FOE. CONTAINERS

Application February 11, 1937, Serial No. 125,202
'21 Claims.
The invention relates to improvements in clo
sures for containers as described in the present
speci?cation and shown in the accompanying
drawing that forms part of the same.
The invention particularly concerns a con
tainer for semi-liquid substances such as shaving
cream, and has for its object to provide an ef
?cient and reliable closure structure incorporat
ing a dispensing ori?ce controlled by a ?oating
10 or loose sealing member.
The closure preferably has a threaded connec
tion with the container, which may be a collap
sible tube, and the ori?ce is encircled by a seat
engaged by the sealing member in the closed po
15 sition of the closure. The sealing member is
shouldered against the container and is supplied
with passages leading to the seat.
The salient feature of this construction is that
by partially turning the closure in a screw-off di
20 rection, the compression of the tube causes the
contents to ?ow into the passages and to forcibly
unseat the sealing member so as to discharge
through the ori?ce. The tightening of the closure
seals off the outlet opening and the ejected ma
terial can be readily removed.
According to this invention it is not necessary
to remove the cap from the tube in order to dis
charge the contents. Furthermore, it is simple
to operate and easy to regulate in order to obtain
the desired quantity of material each time the
tube is used.
Referring to the accompanying drawing, Fig
ure 1 is a perspective view of a container em
(Cl. 221-450)
of a frustum of a cone, which terminates in the
discharge ori?ce l I.
The sealing member is substantially in the
shape of a frustum of a cone and has a face I2
engageable with the seat 10 so as to close the
ori?ce. In the preferred form shown in Figures
2 and 3, a reduced extension is provided as at
l3 for the purpose of constituting a guide.
The rear face l2’ of the sealing member abuts
the end face of the neck ‘I. The passages are 10
composed of the peripheral ?utes l4 communicat
ing with the interior of the tube and terminating
at the face l2. Any number of ?utes may be sup
plied.
In the modi?cation shown in Figures 4 and 5, 15
the extension I3 is dispensed with, and projec
tions as at l5 are furnished to fit into notches
as at It in order to preclude the sealing member
from turning. Additionally, the ?utes are re
placed by ducts ll consisting of small holes com 20
municating with the bore of the neck. The pe
riphery of the sealing member may be threaded
to screw into the cap with the neck.
'
In operation, when the cap is tightened, the
seat ill bears against the face l2 of the sealing 25
member and thus closes the ori?ce. By giving
the cap a partial turn from its closed position and
compressing the tube, the material is urged
through the passages and unseats the sealing
member. This provides a space I 8 through which 30
the material may ?ow to the ori?ce. It is im
portant that the passages communicate with the
seat l5), otherwise the sealing member will stick
in its closed position when the cap is loosened
bodying the present invention.

and a sealing member loosely mounted in the
bore thereof having a face engageable with said
seat to seal off the ori?ce, said sealing member

The collapsible tube 6 is of the conventional
construction, having an externally threaded neck

tainer having a dispensing ori?ce encompassed
by a threaded neck, said closure comprising a cap
threadedly engaged with the neck and having a
bore forming a seat encircling an: ori?ce, and a
opening.
The closure is in the form of a screw cap 8
having the rear portion of its bore internally
threaded as at 9 to threadedly engage the neck 1.
The threaded bore leads to a seat I 0 in the form
